INTRODUCTION: Rural General Practice (GP) surgeries often struggle to employ and retain multidisciplinary team members. Existing research into rural recruitment and retention issues is limited, and usually focussed on doctors. Rural practices often rely on income from dispensing medications; little is known about how maintaining dispensing services contributes to the recruitment and retention of staff. This study aimed to understand the barriers and facilitators to working and remaining in rural dispensing practices, and to explore how the primary care team value dispensing services. METHODS: We undertook semi-structured interviews with multidisciplinary team members of rural dispensing practices across England. Interviews were audio-recorded, transcribed and anonymised. Framework analysis was conducted using Nvivo 12. RESULTS: Seventeen staff members (including GPs, practice nurses, practice managers, dispensers and administrative staff) from 12 rural dispensing practices across England were interviewed. Personal and professional reasons for taking up a role in a rural dispensing practice included perceived career autonomy and development opportunities, and preference for working and living in a rural setting. Key factors impacting retention of staff included revenue generated by dispensing, opportunities for staff development, job satisfaction and the positive work environment. Perceived challenges to retention were the balancing of the required skillset of dispensing with the wages available for the role, lack of skilled job applicants, travel difficulties and negative perceptions of rural primary care practice. DISCUSSION: These findings will inform national policy and practice with the aim of providing further understanding of the drivers and challenges of working in rural dispensing primary care in England.

BACKGROUND: Physical activity and emotional self-management has the potential to enhance health-related quality of life (HRQoL), but few people with chronic kidney disease (CKD) have access to resources and support. The Kidney BEAM trial aims to evaluate whether an evidence-based physical activity and emotional wellbeing self-management programme (Kidney BEAM) leads to improvements in HRQoL in people with CKD. METHODS: This was a prospective, multicentre, randomised waitlist-controlled trial, with health economic analysis and nested qualitative studies. In total, three hundred and four adults with established CKD were recruited from 11 UK kidney units. Participants were randomly assigned to the intervention (Kidney BEAM) or a wait list control group (1:1). The primary outcome was the between-group difference in Kidney Disease Quality of Life (KDQoL) mental component summary score (MCS) at 12 weeks. Secondary outcomes included the KDQoL physical component summary score, kidney-specific scores, fatigue, life participation, depression and anxiety, physical function, clinical chemistry, healthcare utilisation and harms. All outcomes were measured at baseline and 12 weeks, with long-term HRQoL and adherence also collected at six months follow-up. A nested qualitative study explored experience and impact of using Kidney BEAM. RESULTS: 340 participants were randomised to Kidney BEAM (n = 173) and waiting list (n = 167) groups. There were 96 (55%) and 89 (53%) males in the intervention and waiting list groups respectively, and the mean (SD) age was 53 (14) years in both groups. Ethnicity, body mass, CKD stage, and history of diabetes and hypertension were comparable across groups. The mean (SD) of the MCS was similar in both groups, 44.7 (10.8) and 45.9 (10.6) in the intervention and waiting list groups respectively. CONCLUSION: Results from this trial will establish whether the Kidney BEAM self management programme is a cost-effective method of enhancing mental and physical wellbeing of people with CKD.

Abstract
. Background
. Electronic clinical decision support tools (eCDS) are increasingly available to assist General Practitioners (GP) with the diagnosis and management of a range of health conditions. It is unclear whether the use of eCDS tools has an impact on GP workload. This scoping review aimed to identify the available evidence on the use of eCDS tools by health professionals in general practice in relation to their impact on workload and workflow.
.
. Methods
. A scoping review was carried out using the Arksey and O’Malley methodological framework. The search strategy was developed iteratively, with three main aspects: general practice/primary care contexts, risk assessment/decision support tools, and workload-related factors. Three databases were searched in 2019, and updated in 2021, covering articles published since 2009: Medline (Ovid), HMIC (Ovid) and Web of Science (TR). Double screening was completed by two reviewers, and data extracted from included articles were analysed.
.
. Results
. The search resulted in 5,594 references, leading to 95 full articles, referring to 87 studies, after screening. of these, 36 studies were based in the USA, 21 in the UK and 11 in Australia. A further 18 originated from Canada or Europe, with the remaining studies conducted in New Zealand, South Africa and Malaysia. Studies examined the use of eCDS tools and reported some findings related to their impact on workload, including on consultation duration. Most studies were qualitative and exploratory in nature, reporting health professionals’ subjective perceptions of consultation duration as opposed to objectively-measured time spent using tools or consultation durations. Other workload-related findings included impacts on cognitive workload, “workflow” and dialogue with patients, and clinicians’ experience of “alert fatigue”.
.
. Conclusions
. The published literature on the impact of eCDS tools in general practice showed that limited efforts have focused on investigating the impact of such tools on workload and workflow. To gain an understanding of this area, further research, including quantitative measurement of consultation durations, would be useful to inform the future design and implementation of eCDS tools.

BACKGROUND: the e-coachER trial aimed to determine whether adding web-based behavioural support to exercise referral schemes (ERS) increased long-term device-measured physical activity (PA) for patients with chronic conditions, compared to ERS alone, within a randomised controlled trial. This study explores the mechanisms of action of the e-coachER intervention using measures of the behaviour change processes integral to the intervention's logic model. METHODS: Four hundred fifty adults with obesity, diabetes, hypertension, osteoarthritis or history of depression referred to an ERS were recruited in Plymouth, Birmingham and Glasgow. The e-coachER intervention comprising 7-Steps to Health was aligned with Self-Determination Theory and mapped against evidence-based behaviour change techniques (BCTs). Participants completed questionnaires at 0, 4, and 12 months to assess PA and self-reported offline engagement with core BCTs in day-to-day life (including action planning and self-monitoring) and beliefs relating to PA (including perceived importance, confidence, competence, autonomy and support). We compared groups at 4 and 12 months, controlling for baseline measures and other covariates. Mediation analysis using the product of coefficients method was used to determine if changes in process variables mediated intervention effects on moderate to vigorous physical activity (MVPA) recorded by accelerometer and self-report at 4- and 12-months. RESULTS: the internal reliability (Cronbach's alpha) for all multi-item scales was > 0.77. At 4-months, those randomised to e-coachER reported higher levels of PA beliefs relating to importance (1.01, 95% confidence interval (CI): 0.42 to 1.61, p = 0.001), confidence (1.28, 95% CI: 0.57 to 1.98, p 

. Background
. The use of web-based services within primary care (PC) in the National Health Service in England is increasing, with medically underserved populations being less likely to engage with web-based services than other patient groups. Digital facilitation—referring to a range of processes, procedures, and personnel that seek to support patients in the uptake and use of web-based services—may be a way of addressing these challenges. However, the models and impact of digital facilitation currently in use are unclear.
.
.
. Objective
. This study aimed to identify, characterize, and differentiate between different approaches to digital facilitation in PC; establish what is known about the effectiveness of different approaches; and understand the enablers of digital facilitation.
.
.
. Methods
. Adopting scoping review methodology, we searched academic databases (PubMed, EMBASE, CINAHL, Web of Science, and Cochrane Library) and gray literature published between 2015 and 2020. We conducted snowball searches of reference lists of included articles and articles identified during screening as relevant to digital facilitation, but which did not meet the inclusion criteria because of article type restrictions. Titles and abstracts were independently screened by 2 reviewers. Data from eligible studies were analyzed using a narrative synthesis approach.
.
.
. Results
. A total of 85 publications were included. Most (71/85, 84%) were concerned with digital facilitation approaches targeted at patients (promotion of services, training patients to improve their technical skills, or other guidance and support). Further identified approaches targeted PC staff to help patients (eg, improving staff knowledge of web-based services and enhancing their technical or communication skills). Qualitative evidence suggests that some digital facilitation may be effective in promoting the uptake and use of web-based services by patients (eg, recommendation of web-based services by practice staff and coaching). We found little evidence that providing patients with initial assistance in registering for or accessing web-based services leads to increased long-term use. Few studies have addressed the effects of digital facilitation on health care inequalities. Those that addressed this suggested that providing technical training for patients could be effective, at least in part, in reducing inequalities, although not entirely. Factors affecting the success of digital facilitation include perceptions of the usefulness of the web-based service, trust in the service, patients’ trust in providers, the capacity of PC staff, guidelines or regulations supporting facilitation efforts, and staff buy-in and motivation.
.
.
. Conclusions
. Digital facilitation has the potential to increase the uptake and use of web-based services by PC patients. Understanding the approaches that are most effective and cost-effective, for whom, and under what circumstances requires further research, including rigorous evaluations of longer-term impacts. As efforts continue to increase the use of web-based services in PC in England and elsewhere, we offer an early typology to inform conceptual development and evaluations.

BACKGROUND: Guidelines recommend measuring blood pressure (BP) in both arms, adopting the higher arm readings for diagnosis and management. Data to support this recommendation are lacking. We evaluated associations of higher and lower arm systolic BPs with diagnostic and treatment thresholds, and prognosis in hypertension, using data from the Inter-arm Blood Pressure Difference-Individual Participant Data Collaboration. METHODS: One-stage multivariable Cox regression models, stratified by study, were used to examine associations of higher or lower reading arm BPs with cardiovascular mortality, all-cause mortality, and cardiovascular events, in individual participant data meta-analyses pooled from 23 cohorts. Cardiovascular events were modelled for Framingham and atherosclerotic cardiovascular disease risk scores. Model fit was compared throughout using Akaike information criteria. Proportions reclassified across guideline recommended intervention thresholds were also compared. RESULTS: We analyzed 53 172 participants: mean age 60 years; 48% female. Higher arm BP, compared with lower arm, reclassified 12% of participants at either 130 or 140 mm Hg systolic BP thresholds (both P

BACKGROUND: Systolic inter-arm differences (IAD) in blood pressure (BP) contribute independently to cardiovascular risk estimates. This can be used to refine predicted risk and guide personalised interventions. AIM: to model the effect of accounting for IAD in cardiovascular risk estimation in a primary care population free of pre-existing cardiovascular disease. DESIGN & SETTING: a cross-sectional analysis of people aged 40-75 years attending NHS Health Checks in one general practice in England. METHOD: Simultaneous bilateral BP measurements were made during health checks. QRISK2, atherosclerotic cardiovascular disease (ASCVD), and Framingham cardiovascular risk scores were calculated before and after adjustment for IAD using previously published hazard ratios. Reclassification across guideline-recommended intervention thresholds was analysed. RESULTS: Data for 334 participants were analysed. Mean (standard deviation) QRISK2, ASCVD, and Framingham scores were 8.0 (6.9), 6.9 (6.5), and 10.7 (8.1), respectively, rising to 8.9 (7.7), 7.1 (6.7), and 11.2 (8.5) after adjustment for IAD. Thirteen (3.9%) participants were reclassified from below to above the 10% QRISK2 threshold, three (0.9%) for the ASCVD 10% threshold, and nine (2.7%) for the Framingham 15% threshold. CONCLUSION: Knowledge of IAD can be used to refine cardiovascular risk estimates in primary care. By accounting for IAD, recommendations of interventions for primary prevention of cardiovascular disease can be personalised and treatment offered to those at greater than average risk. When assessing elevated clinic BP readings, both arms should be measured to allow fuller estimation of cardiovascular risk.

Experiences of sexual violence, childhood sexual abuse, and sexual assault are common across all societies. These experiences damage physical and mental health, coping ability, and relationships with others. Given the breadth and magnitude of impacts, it is imperative that there are effective, accessible services to support victim-survivors, ease suffering, and empower people to cope, recover and thrive. Service provision for this population in the United Kingdom is complex and has been hit substantially by austerity. Since positive social support can buffer against negative impacts, peer support may be an effective approach. The aim of this exploratory study was to capture the views and perspectives of professional stakeholders concerning service provision for victim-survivors, particularly perceptions of peer support.In-depth semistructured interviews were conducted in the UK during 2018 with six professional stakeholders, highly experienced in the field of service provision for victim-survivors of sexual violence and abuse. An abductive approach to analysis was used, applying principles from thematic analysis. Our sample comprised four females and two males, and their roles included psychiatrist, general practitioner, service improvement facilitator, and senior positions within victim-survivor organizations.Interviews highlighted models of peer support for this population, good practice and safety considerations, and a lack of uniformity regarding quality and governance standards across the sector. Findings indicated that current funding models impact negatively on victim-survivor services, and that provision is fragmented and insufficient across statutory and not-for-profit sectors. The influence of the medical model upon service provision was evident, which resulted in apprehension around support delivered in less-usual forms-including peer support. Further research is needed to explore the potential of peer support for victim-survivors of sexual violence and abuse.

BACKGROUND: Difficult-to-treat depression (DTD) presents a substantial health care challenge, with around one-third of people diagnosed with a depressive episode in the UK finding that their symptoms persist following treatment. This study aimed to identify priority research questions (RQs) that could inform the development of new and improved treatments, interventions, and support for people with DTD. METHODS: Using an adapted Child Health and Nutrition Research Initiative (CHNRI) method, this national prioritisation exercise engaged 60 leading researchers and health care professionals in the UK, as well as 25 wider stakeholders with relevant lived experience to produce a ranked list of priority RQs in DTD. The final list of 99 distinct RQs was independently scored by 42 individuals against a list of five criteria: answerability, effectiveness, impact on health, deliverability, and equity. RESULTS: Highly ranked RQs covered a range of novel and existing treatments. The three highest scoring RQs included evaluation of psychological and pharmacological therapies (eg, behavioural activation, and augmentation therapies), as well as social interventions to reduce loneliness or increase support for people with DTD. CONCLUSIONS: This exercise identified and prioritised 99 RQs that could inform future research and funding decisions over the next five years. The results of this research could improve treatment and support for people affected by DTD. It also serves as an example of ways in which the CHNRI method can be adapted in a collaborative manner to provide a more active role for patients, carers, and health care professionals.

BACKGROUND: the English Cancer Patient Experience Survey (CPES) is a regularly conducted survey measuring the experience of cancer patients. We studied the survey's underlying structure using factor analysis to identify potential for improvements in reporting or questionnaire design. METHODS: Cancer Patient Experience Survey 2015 respondents (n = 71,186, response rate 66%) were split into two random subgroups. Using exploratory factor analysis (EFA) on the first subgroup, we identified the survey's latent structure. EFA was then applied to 12 sets of items. A first ("core") set was formed by questions that applied to all participants. The subsequent sets contained the "core set" plus questions corresponding to specific care pathways/patient groups. We used confirmatory factor analysis (CFA) on the second data subgroup for cross-validation. RESULTS: the EFA suggested that five latent factors underlie the survey's core questions. Analysis on the remaining 11 care pathway/patient group items also indicated the same five latent factors, although additional factors were present for questions applicable to patients with an overnight stay or those accessing specialist nursing. The five factors models had an excellent fit (comparative fit index = 0.95, root mean square error of approximation = 0.045 for core set of questions). Items loading on each factor generally corresponded to a specific section or subsection of the questionnaire. CFA findings were concordant with the EFA patterns. CONCLUSION: the findings suggest five coherent underlying sub-constructs relating to different aspects of cancer health care. The findings support the construction of evidence-based composite indicators for different domains of experience and provide options for survey re-design.

IntroductionBCG vaccination modulates immune responses to unrelated pathogens. This off-target effect could reduce the impact of emerging pathogens. As a readily available, inexpensive intervention that has a well-established safety profile, BCG is a good candidate for protecting healthcare workers (HCWs) and other vulnerable groups against COVID-19.Methods and analysisThis international multicentre phase III randomised controlled trial aims to determine if BCG vaccination reduces the incidence of symptomatic and severe COVID-19 at 6 months (co-primary outcomes) compared with no BCG vaccination. We plan to randomise 10 078 HCWs from Australia, the Netherlands, Spain, the UK and Brazil in a 1:1 ratio to BCG vaccination or no BCG (control group). The participants will be followed for 1 year with questionnaires and collection of blood samples. For any episode of illness, clinical details will be collected daily, and the participant will be tested for SARS-CoV-2 infection. The secondary objectives are to determine if BCG vaccination reduces the rate, incidence, and severity of any febrile or respiratory illness (including SARS-CoV-2), as well as work absenteeism. The safety of BCG vaccination in HCWs will also be evaluated. Immunological analyses will assess changes in the immune system following vaccination, and identify factors associated with susceptibility to or protection against SARS-CoV-2 and other infections.Ethics and disseminationEthical and governance approval will be obtained from participating sites. Results will be published in peer-reviewed open-access journals. The final cleaned and locked database will be deposited in a data sharing repository archiving system.Trial registrationClinicalTrials.gov NCT04327206

INTRODUCTION AND HYPOTHESIS: to determine whether primary care nurses with no prior experience can, after training, provide effective supervised pelvic floor muscle training (PFMT) by a three-group parallel randomized controlled trial (RCT): primary care nurse, urogynaecology nurse specialist and controls undertaken in 11 primary care/general practices, covering urban and rural settings in SW England. The sample consisted of 337 women with weak pelvic floor muscles (Modified Oxford Score 2 or less) in a randomly sampled survey. METHODS: Following detailed instruction and training, primary care nurses recruited patients who were randomized to PFMT provided by them, a urogynaecology nurse specialist or a 'no training' control group. The primary outcome measure to assess the effectiveness of training was pelvic floor muscle strength as measured by perineometry. RESULTS: Two hundred forty women aged 19 to 76 (median 49) years were recruited. After 3 months there was an increase in strength in both intervention groups compared with controls: median differences (95% CI) were 3.0 (0.3, 6.0) cmH2O higher for the primary care nurse group (n = 50) compared to the control group (n = 56; p = 0.02) and 4.3 (1.0, 7.3) cmH2O for the urogynaecology nurse specialist group (n = 53) compared to control (p 

BACKGROUND: the aim of this work was to show the feasibility of providing a comprehensive portrait of regional primary care performance. METHODS: the TRANSFORMATION study used a mixed-methods concurrent study design where we analyzed survey data and case studies. Data were collected in British Columbia, Ontario and Nova Scotia. Patient's Medical Home (PMH) pillar scores were created by calculating mean clinic-level scores across regions. Scores and qualitative themes were compared. RESULTS: Participation included 86 practices (n = 1,929 patients; n = 117 clinicians). Regions had differential attainment towards PMH orientation with respect to infrastructure; community adaptiveness and accountability; and patient and family partnered care. The lowest PMH attainment for all regions were observed in connected care; accessible care; measurement, continuous quality improvement and research; and training, education and continuing professional development. CONCLUSIONS: Comprehensive performance reporting that draws on multiple data sources in primary care is possible. Regional portraits highlighting many of the key pillars of a PMH approach to primary care show that despite differences in policy contexts, achieving a PMH remains elusive.

BackgroundClinical guidelines advise GPs in England which patients warrant an urgent referral for suspected cancer. This study assessed how often GPs follow the guidelines, whether certain patients are less likely to be referred, and how many patients were diagnosed with cancer within 1 year of non-referral.MethodsWe used linked primary care (Clinical Practice Research Datalink), secondary care (Hospital Episode Statistics) and cancer registration data. Patients presenting with haematuria, breast lump, dysphagia, iron-deficiency anaemia, post-menopausal or rectal bleeding for the first time during 2014–2015 were included (for ages where guidelines recommend urgent referral). Logistic regression was used to investigate whether receiving a referral was associated with feature type and patient characteristics. Cancer incidence (based on recorded diagnoses in cancer registry data within 1 year of presentation) was compared between those receiving and those not receiving referrals.Results48 715 patients were included, of which 40% (n=19 670) received an urgent referral within 14 days of presentation, varying by feature from 17% (dysphagia) to 68% (breast lump). Young patients (18–24 vs 55–64 years; adjusted OR 0.20, 95% CI 0.10 to 0.42, p<0.001) and those with comorbidities (4 vs 0 comorbidities; adjusted OR 0.87, 95% CI 0.80 to 0.94, p<0.001) were less likely to receive a referral. Associations between patient characteristics and referrals differed across features: among patients presenting with anaemia, breast lump or haematuria, those with multi-morbidity, and additionally for breast lump, more deprived patients were less likely to receive a referral. of 29 045 patients not receiving a referral, 3.6% (1047) were diagnosed with cancer within 1 year, ranging from 2.8% for rectal bleeding to 9.5% for anaemia.ConclusionsGuideline recommendations for action are not followed for the majority of patients presenting with common possible cancer features. A significant number of these patients developed cancer within 1 year of their consultation, indicating scope for improvement in the diagnostic process.

BACKGROUND: Most patients obtain medications from pharmacies by prescription, but rural general practices can dispense medications. The clinical implications of this difference in drug delivery are unknown. This study hypothesised that dispensing status may be associated with better medication adherence. This could impact intermediate clinical outcomes dependent on medication adherence in, for example, hypertension or diabetes. AIM: to investigate whether dispensing status is associated with differences in achievement of Quality and Outcomes Framework (QOF) indicators that rely on medication adherence. DESIGN AND SETTING: Cross-sectional analysis of QOF data for 7392 general practices in England. METHOD: QOF data from 1 April 2016 to 31 March 2017 linked to dispensing status for general practices with list sizes ≥1000 in England were analysed. QOF indicators were categorised according to whether their achievement depended on a record of prescribing only, medication adherence, or neither. Differences were estimated between dispensing and non-dispensing practices using mixed-effects logistic regression, adjusting for practice population age, sex, deprivation, list size, single-handed status, and rurality. RESULTS: Data existed for 7392 practices; 1014 (13.7%) could dispense. Achievement was better in dispensing practices than in non-dispensing practices for seven of nine QOF indicators dependent on adherence, including blood pressure targets. Only one of ten indicators dependent on prescribing but not adherence displayed better achievement; indicators unrelated to prescribing showed a trend towards higher achievement by dispensing practices. CONCLUSION: Dispensing practices may achieve better clinical outcomes than prescribing practices. Further work is required to explore underlying mechanisms for these observations and to directly study medication adherence rates.

. Background
. There is modest evidence that exercise referral schemes increase physical activity in inactive individuals with chronic health conditions. There is a need to identify additional ways to improve the effects of exercise referral schemes on long-term physical activity.
.
.
. Objectives
. To determine if adding the e-coachER intervention to exercise referral schemes is more clinically effective and cost-effective in increasing physical activity after 1 year than usual exercise referral schemes.
.
.
. Design
. A pragmatic, multicentre, two-arm randomised controlled trial, with a mixed-methods process evaluation and health economic analysis. Participants were allocated in a 1 : 1 ratio to either exercise referral schemes plus e-coachER (intervention) or exercise referral schemes alone (control).
.
.
. Setting
. Patients were referred to exercise referral schemes in Plymouth, Birmingham and Glasgow.
.
.
. Participants
. There were 450 participants aged 16–74 years, with a body mass index of 30–40 kg/m2, with hypertension, prediabetes, type 2 diabetes, lower limb osteoarthritis or a current/recent history of treatment for depression, who were also inactive, contactable via e-mail and internet users.
.
.
. Intervention
. e-coachER was designed to augment exercise referral schemes. Participants received a pedometer and fridge magnet with physical activity recording sheets, and a user guide to access the web-based support in the form of seven ‘steps to health’. e-coachER aimed to build the use of behavioural skills (e.g. self-monitoring) while strengthening favourable beliefs in the importance of physical activity, competence, autonomy in physical activity choices and relatedness. All participants were referred to a standard exercise referral scheme.
.
.
. Primary outcome measure
. Minutes of moderate and vigorous physical activity in ≥ 10-minute bouts measured by an accelerometer over 1 week at 12 months, worn ≥ 16 hours per day for ≥ 4 days including ≥ 1 weekend day.
.
.
. Secondary outcomes
. Other accelerometer-derived physical activity measures, self-reported physical activity, exercise referral scheme attendance and EuroQol-5 Dimensions, five-level version, and Hospital Anxiety and Depression Scale scores were collected at 4 and 12 months post randomisation.
.
.
. Results
. Participants had a mean body mass index of 32.6 (standard deviation) 4.4 kg/m2, were referred primarily for weight loss and were mostly confident self-rated information technology users. Primary outcome analysis involving those with usable data showed a weak indicative effect in favour of the intervention group (n = 108) compared with the control group (n = 124); 11.8 weekly minutes of moderate and vigorous physical activity (95% confidence interval –2.1 to 26.0 minutes; p = 0.10). Sixty-four per cent of intervention participants logged on at least once; they gave generally positive feedback on the web-based support. The intervention had no effect on other physical activity outcomes, exercise referral scheme attendance (78% in the control group vs. 75% in the intervention group) or EuroQol-5 Dimensions, five-level version, or Hospital Anxiety and Depression Scale scores, but did enhance a number of process outcomes (i.e. confidence, importance and competence) compared with the control group at 4 months, but not at 12 months. At 12 months, the intervention group incurred an additional mean cost of £439 (95% confidence interval –£182 to £1060) compared with the control group, but generated more quality-adjusted life-years (mean 0.026, 95% confidence interval 0.013 to 0.040), with an incremental cost-effectiveness ratio of an additional £16,885 per quality-adjusted life-year.
.
.
. Limitations
. A significant proportion (46%) of participants were not included in the primary analysis because of study withdrawal and insufficient device wear-time, so the results must be interpreted with caution. The regression model fit for the primary outcome was poor because of the considerable proportion of participants [142/243 (58%)] who recorded no instances of ≥ 10-minute bouts of moderate and vigorous physical activity at 12 months post randomisation.
.
.
. Future work
. The design and rigorous evaluation of cost-effective and scalable ways to increase exercise referral scheme uptake and maintenance of moderate and vigorous physical activity are needed among patients with chronic conditions.
.
.
. Conclusions
. Adding e-coachER to usual exercise referral schemes had only a weak indicative effect on long-term rigorously defined, objectively assessed moderate and vigorous physical activity. The provision of the e-coachER support package led to an additional cost and has a 63% probability of being cost-effective based on the UK threshold of £30,000 per quality-adjusted life-year. The intervention did improve some process outcomes as specified in our logic model.

BACKGROUND: General practices are required to provide online booking to patients in line with policy to digitise access. However, uptake of online booking by patients is currently low and there is little evidence about awareness and use by different patient groups. AIM: to examine variability in awareness and use of online appointment booking in general practice. METHOD: Secondary analysis of two questions from the GP Practice Survey data (2018) asking about awareness and use of online booking of appointments. Multivariable logistic regression was used to examine associations with age, gender, ethnicity, deprivation, the presence of a long-term condition, long-term sickness and being deaf. RESULTS: in total, 43.3% (277 278/647 064) of responders reported being aware of being able to book appointments online, while only 15% (93 671/641 073) reported doing so. There was evidence of variation by all factors considered, with strong deprivation gradients in both awareness and use (for example, most versus least deprived quintile OR for use: 0.63 (95% CI = 0.61 to 0.65). There was a reduction in awareness and use in patients >75 years of age. Patients with long-term conditions were more aware and more likely to use online booking. CONCLUSION: While over 40% of patients know that they can book appointment online, the number that actually do so is far lower. With the constant push for online services within the NHS and the roll out of the NHS app, practices should be aware that not all patient groups will book appointments online and that other routes of access need to be maintained to avoid widening health inequalities.

BackgroundThere are ambitious overseas recruitment targets to alleviate current GP shortages in the UK. GP training in European Economic Area (EEA) countries is recognised by the General Medical Council (GMC) as equivalent UK training; non-EEA GPs must obtain a Certificate of Eligibility for General Practice Registration (CEGPR), demonstrating equivalence to UK-trained GPs. The CEGPR may be a barrier to recruiting GPs from non-EEA countries. It is important to facilitate the most streamlined route into UK general practice while maintaining registration standards and patient safety.AimTo apply a previously published mapping methodology to four non-EEA countries: South Africa, US, Canada, and New Zealand.Design & settingDesk-based research was undertaken. This was supplemented with stakeholder interviews.MethodThe method consisted of: (1) a rapid review of 13 non-EEA countries using a structured mapping framework, and publicly available website content and country-based informant interviews; (2) mapping of five ‘domains’ of comparison between four overseas countries and the UK (healthcare context, training pathway, curriculum, assessment, and continuing professional development (CPD) and revalidation). Mapping of the domains involved desk-based research. A red, amber, or green (RAG) rating was applied to indicate the degree of alignment with the UK.ResultsAll four countries were rated ‘green’. Areas of differences that should be considered by regulatory authorities when designing streamlined CEGPR processes for these countries include: healthcare context (South Africa and US), CPD and revalidation (US, Canada, and South Africa), and assessments (New Zealand).ConclusionMapping these four non-EEA countries to the UK provides evidence of utility of the systematic method for comparing GP training between countries, and may support the UK’s ambitions to recruit more GPs to alleviate UK GP workforce pressures.

Introduction Performance measurement has been recognized as key to transforming primary care (PC). Yet, performance reporting in PC lags behind even though high-performing PC is foundational to an effective and efficient health care system. Objectives We used administrative data from three Canadian provinces, British Columbia, Ontario and Nova Scotia, to: 1) identify and develop a core set of PC performance indicators using administrative data and 2) examine their ability to capture PC performance. Methods Administrative data used included Physician Billings, Discharge Abstract Database, the National Ambulatory Care and Reporting System database, Census and Vital Statistics. Indicators were compiled based on a literature review of PC indicators previously developed with administrative data available in Canada (n=158). We engaged in iterative discussions to assess data conformity, completeness, and plausibility of results in all jurisdictions. Challenges to creating comparable algorithms were examined through content analysis and research team discussions, which included clinicians, analysts, and health services researchers familiar with PC. Results Our final list included 21 PC performance indicators pertaining to 1) technical care (n=4), 2) continuity of care (n=6), and 3) health services utilization (n=11). Establishing comparable algorithms across provinces was possible though time intensive. A major challenge was inconsistent data elements. Ease of data access, and a deep understanding of the data and practice context, was essential for selecting the most appropriate data elements. Conclusions This project is unique in creating algorithms to measure PC performance across provinces. It was essential to balance internal validity of the indicators within a province and external validity across provinces. The intuitive desire of having the exact same coding across provinces was infeasible due to lack of standardized PC data. Rather, a context-tailored definition was developed for each jurisdiction. This work serves as an example for developing comparable PC performance indicators across different provincial/territorial jurisdictions.

BACKGROUND: There is a lack of evidence to guide treatment of comorbid depression and anxiety. Preliminary evidence suggests mirtazapine may be effective in treating patients with both depression and anxiety symptoms. METHODS: We undertook a secondary analysis of mirtazapine (MIR): a placebo-controlled trial of the addition of mirtazapine to a selective serotonin reuptake inhibitor or serotonin-norepinephrine reuptake inhibitor in treatment-resistant depression (TRD) in primary care. We subdivided participants into three groups by baseline generalized anxiety disorder score (GAD-7): severe (GAD-7 ⩾ 16), moderate (GAD-7 = 11-15), no/mild (GAD-7 ⩽ 10). We used linear regression including likelihood-ratio testing of interaction terms to assess how baseline anxiety altered the response of participants to mirtazapine as measured by 12-week GAD-7 and Beck Depression Inventory II (BDI-II) scores. RESULTS: Baseline generalized anxiety moderated mirtazapine's effect as measured by GAD-7 (p = 0.041) and BDI-II (p = 0.088) at 12 weeks. Participants with severe generalized anxiety receiving mirtazapine had lower 12-week GAD-7 score (adjusted difference between means (ADM) -2.82, 95% confidence interval (CI) -0.69 to -4.95) and larger decreases in BDI-II score (ADM -6.36, 95% CI -1.60 to -10.84) than placebo. Conversely, there was no anxiolytic benefit (ADM 0.28, 95% CI -1.05 to 1.60) or antidepressant benefit (ADM -0.17, 95% CI -3.02 to 2.68) compared with placebo in those with no/mild generalized anxiety. CONCLUSIONS: These findings extend the evidence for the effectiveness of mirtazapine to reduce generalized anxiety in TRD in primary care. These results may inform targeted prescribing in depression based on concurrent anxiety symptoms, although these conclusions are constrained by the post-hoc nature of this analysis.

OBJECTIVE: to assess the effects of interventions aimed at involving older people with multimorbidity in decision-making about their healthcare during primary care consultations. METHODS: Cochrane methodological procedures were applied. Searches covered all relevant trial registries and databases. Randomised controlled trials were identified where interventions had been compared with usual care/ control/ another intervention. A narrative synthesis is presented; meta-analysis was not appropriate. RESULTS: 8160 abstracts and 54 full-text articles were screened. Three studies were included, involving 1879 patient participants. Interventions utilised behaviour change theory; cognitive-behavioural therapy and motivational interviewing; multidisciplinary, holistic patient review and organisational changes. No studies reported the primary outcome 'patient involvement in decision-making about their healthcare'. Patient involvement was evident in the theory underpinning interventions. Certainty of evidence (assessed using GRADE) was limited by small studies and inconsistency in secondary outcomes measured. CONCLUSION: the evidence base is currently too limited to interpret with certainty. Transparency in design and consistency in evaluation, using validated measures, is required for future interventions involving older patients with multimorbidity in decisions about their healthcare. PRACTICE IMPLICATIONS: There is a large gap between clinical guidelines for multimorbidity and an evidence base for implementation of their recommendations during primary care consultations with older people.

Background: There are current concerns about whether appropriate support is provided for sexual abuse and assault survivors. We reviewed the published evidence for peer-led groups in the care of survivors.Aims: to determine the health and wellbeing outcomes of peer-led, group-based interventions for adult survivors who have experienced sexual abuse and assault and describe the experiences of participants attending these groups.Method: Systematic review. The following databases were searched: Medline, PsycINFO, Embase, Cochrane Library, Web of Science, Sociological Abstracts, IBSS. Papers focusing on adults using any research methodology were included. Quality appraisal was completed using the Mixed Methods Appraisal Tool (MMAT). Thematic analysis was undertaken using methods of constant comparison.Results: Initial, and updated searches identified 16,724 potentially eligible articles. of these, eight were included. Thematic analysis revealed that peer-led group-based interventions have positive impact on participants' psychological, physical and interpersonal well-being. Participation also presents challenges for survivors. However, there is a mutuality and interconnected benefit between the triggering of difficult emotions due to participation and the healing experiences gained.Conclusions: Scientific evidence of peer-led, group-based, approaches for adult survivors of sexual abuse and assault is limited, although generally suggestive of benefits to such individuals.

BACKGROUND: the number of older people with multiple health problems is increasing worldwide. This creates a strain on clinicians and the health service when delivering clinical care to this patient group, who themselves carry a large treatment burden. Despite shared decision-making being acknowledged by healthcare organisations as a priority feature of clinical care, older patients with multimorbidity are less often involved in decision-making when compared with younger patients, with some evidence suggesting associated health inequalities. Interventions aimed at facilitating shared decision-making between doctors and patients are outdated in their assessments of today's older patient population who need support in prioritising complex care needs in order to maximise quality of life and day-to-day function. AIMS: to undertake feasibility testing of an intervention ('VOLITION') aimed at facilitating the involvement of older patients with more than one long-term health problem in shared decision-making about their healthcare during GP consultations.To inform the design of a fully powered trial to assess intervention effectiveness. METHODS: This study is a cluster randomised controlled feasibility trial with qualitative process evaluation interviews. Participants are patients, aged 65 years and above with more than one long-term health problem (multimorbidity), and the GPs that they consult with. This study aims to recruit 6 GP practices, 18 GPs and 180 patients. The intervention comprises two components: (i) a half-day training workshop for GPs in shared decision-making; and (ii) a leaflet for patients that facilitate their engagement with shared decision-making. Intervention implementation will take 2 weeks (to complete delivery of both patient and GP components), and follow-up duration will be 12 weeks (from index consultation and commencement of data collection to final case note review and process evaluation interview). The trial will run from 01/01/20 to 31/01/21; 1 year 31 days. DISCUSSION: Shared decision-making for older people with multimorbidity in general practice is under-researched. Emerging clinical guidelines advise a patient-centred approach, to reduce treatment burden and focus on quality of life alongside disease control. The systematic development, testing and evaluation of an intervention is warranted and timely. This study will test the feasibility of implementing a new intervention in UK general practice for future evaluation as a part of routine care.

BACKGROUND: Current funding arrangements for undergraduate medical student placements in general practice are widely regarded as outdated, inequitable, and in need of urgent review. AIM: to undertake a detailed costing exercise to inform the setting of a national English tariff for undergraduate medical student placements in general practice. DESIGN AND SETTING: a cost-collection survey in teaching practices across all regions of England between January 2017 and February 2017. METHOD: a cost-collection template was sent to 50 selected teaching practices across all 25 medical schools in England following the development of a cost-collection tool and an initial pilot study. Detailed guidance on completion was provided for practices. Data were analysed by the Department of Health and Social Care. RESULTS: a total of 49 practices submitted data. The mean cost per half-day student placement in general practice was 111 GBP, 95% confidence interval = 100 to 121 (146 USD), with small differences between students in different years of study. Based on 10 sessions per student per week this equated to around 1100 GBP (1460 USD) per student placement week. CONCLUSION: the costs of undergraduate placements in general practice are considerably greater than funding available at time of writing, and broadly comparable with secondary care funding in the same period. The actual cost of placing a medical student full time in general practice for a 37-week academic year is 40 700 GBP (53 640 USD) compared with the average payment rate of only 22 000 GBP (28 990 USD) per year at the time this study was undertaken.

OBJECTIVE: This study aimed to develop a risk prediction model identifying general practices at risk of workforce supply-demand imbalance. DESIGN: This is a secondary analysis of routine data on general practice workforce, patient experience and registered populations (2012 to 2016), combined with a census of general practitioners' (GPs') career intentions (2016). SETTING/PARTICIPANTS: a hybrid approach was used to develop a model to predict workforce supply-demand imbalance based on practice factors using historical data (2012-2016) on all general practices in England (with over 1000 registered patients n=6398). The model was applied to current data (2016) to explore future risk for practices in South West England (n=368). PRIMARY OUTCOME MEASURE: the primary outcome was a practice being in a state of workforce supply-demand imbalance operationally defined as being in the lowest third nationally of access scores according to the General Practice Patient Survey and the highest third nationally according to list size per full-time equivalent GP (weighted to the demographic distribution of registered patients and adjusted for deprivation). RESULTS: Based on historical data, the predictive model had fair to good discriminatory ability to predict which practices faced supply-demand imbalance (area under receiver operating characteristic curve=0.755). Predictions using current data suggested that, on average, practices at highest risk of future supply-demand imbalance are currently characterised by having larger patient lists, employing more nurses, serving more deprived and younger populations, and having considerably worse patient experience ratings when compared with other practices. Incorporating findings from a survey of GP's career intentions made little difference to predictions of future supply-demand risk status when compared with expected future workforce projections based only on routinely available data on GPs' gender and age. CONCLUSIONS: it is possible to make reasonable predictions of an individual general practice's future risk of undersupply of GP workforce with respect to its patient population. However, the predictions are inherently limited by the data available.

BACKGROUND: People increasingly communicate online, using visual communication mediums such as Skype and FaceTime. Growing demands on primary care services mean that new ways of providing patient care are being considered. Video consultation (VC) over the internet is one such mode. AIM: to explore patients' and clinicians' experiences of VC. DESIGN AND SETTING: Semi-structured interviews in UK primary care. METHOD: Primary care clinicians were provided with VC equipment. They invited patients requiring a follow-up consultation to an online VC using the Attend Anywhere web-based platform. Participating patients required a smartphone, tablet, or video-enabled computer. Following VCs, semi-structured interviews were conducted with patients (n = 21) and primary care clinicians (n = 13), followed by a thematic analysis. RESULTS: Participants reported positive experiences of VC, and stated that VC was particularly helpful for them as working people and people with mobility or mental health problems. VCs were considered superior to telephone consultations in providing visual cues and reassurance, building rapport, and improving communication. Technical problems, however, were common. Clinicians felt, for routine use, VCs must be more reliable and seamlessly integrated with appointment systems, which would require upgrading of current NHS IT systems. CONCLUSION: the visual component of VCs offers distinct advantages over telephone consultations. When integrated with current systems VCs can provide a time-saving alternative to face-to-face consultations when formal physical examination is not required, especially for people who work. Demand for VC services in primary care is likely to rise, but improved technical infrastructure is required to allow VC to become routine. However, for complex or sensitive problems face-to-face consultations remain preferable.

BACKGROUND: Growing demands on primary care services have led to policymakers promoting video consultations (VCs) to replace routine face-to-face consultations (FTFCs) in general practice. AIM: to explore the content, quality, and patient experience of VC, telephone (TC), and FTFCs in general practice. DESIGN AND SETTING: Comparison of audio-recordings of follow-up consultations in UK primary care. METHOD: Primary care clinicians were provided with video-consulting equipment. Participating patients required a smartphone, tablet, or computer with camera. Clinicians invited patients requiring a follow-up consultation to choose a VC, TC, or FTFC. Consultations were audio-recorded and analysed for content and quality. Participant experience was explored in post-consultation questionnaires. Case notes were reviewed for NHS resource use. RESULTS: of the recordings, 149/163 were suitable for analysis. VC recruits were younger, and more experienced in communicating online. FTFCs were longer than VCs (mean difference +3.7 minutes, 95% confidence interval [CI] = 2.1 to 5.2) or TCs (+4.1 minutes, 95% CI = 2.6 to 5.5). On average, patients raised fewer problems in VCs (mean 1.5, standard deviation [SD] 0.8) compared with FTFCs (mean 2.1, SD 1.1) and demonstrated fewer instances of information giving by clinicians and patients. FTFCs scored higher than VCs and TCs on consultation-quality items. CONCLUSION: VC may be suitable for simple problems not requiring physical examination. VC, in terms of consultation length, content, and quality, appeared similar to TC. Both approaches appeared less 'information rich' than FTFC. Technical problems were common and, though patients really liked VC, infrastructure issues would need to be addressed before the technology and approach can be mainstreamed in primary care.

BackgroundUK general practice faces a workforce crisis, with general practitioner (GP) shortages, organisational change, substantial pressures across the whole health-care system and an ageing population with increasingly complex health needs. GPs require lengthy training, so retaining the existing workforce is urgent and important.Objectives(1) to identify the key policies and strategies that might (i) facilitate the retention of experienced GPs in direct patient care or (ii) support the return of GPs following a career break. (2) to consider the feasibility of potentially implementing those policies and strategies.DesignThis was a comprehensive, mixed-methods study.SettingThis study took place in primary care in England.ParticipantsGeneral practitioners registered in south-west England were surveyed. Interviews were with purposively selected GPs and primary care stakeholders. A RAND/UCLA Appropriateness Method (RAM) panel comprised GP partners and GPs working in national stakeholder organisations. Stakeholder consultations included representatives from regional and national groups.Main outcome measuresSystematic review – factors affecting GPs’ decisions to quit and to take career breaks. Survey – proportion of GPs likely to quit, to take career breaks or to reduce hours spent in patient care within 5 years of being surveyed. Interviews – themes relating to GPs’ decision-making. RAM – a set of policies and strategies to support retention, assessed as ‘appropriate’ and ‘feasible’. Predictive risk modelling – predictive model to identify practices in south-west England at risk of workforce undersupply within 5 years. Stakeholder consultation – comments and key actions regarding implementing emergent policies and strategies from the research.ResultsPast research identified four job-related ‘push’ factors associated with leaving general practice: (1) workload, (2) job dissatisfaction, (3) work-related stress and (4) work–life balance. The survey, returned by 2248 out of 3370 GPs (67%) in the south-west of England, identified a high likelihood of quitting (37%), taking a career break (36%) or reducing hours (57%) within 5 years. Interviews highlighted three drivers of leaving general practice: (1) professional identity and value of the GP role, (2) fear and risk associated with service delivery and (3) career choices. The RAM panel deemed 24 out of 54 retention policies and strategies to be ‘appropriate’, with most also considered ‘feasible’, including identification of and targeted support for practices ‘at risk’ of workforce undersupply and the provision of formal career options for GPs wishing to undertake portfolio roles. Practices at highest risk of workforce undersupply within 5 years are those that have larger patient list sizes, employ more nurses, serve more deprived and younger populations, or have poor patient experience ratings. Actions for national organisations with an interest in workforce planning were identified. These included collection of data on the current scope of GPs’ portfolio roles, and the need for formal career pathways for key primary care professionals, such as practice managers.LimitationsThe survey, qualitative research and modelling were conducted in one UK region. The research took place within a rapidly changing policy environment, providing a challenge in informing emergent policy and practice.ConclusionsThis research identifies the basis for current concerns regarding UK GP workforce capacity, drawing on experiences in south-west England. Policies and strategies identified by expert stakeholders after considering these findings are likely to be of relevance in addressing GP retention in the UK. Collaborative, multidisciplinary research partnerships should investigate the effects of rolling out some of the policies and strategies described in this report.Study registrationThis study is registered as PROSPERO CRD42016033876 and UKCRN ID number 20700.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

OBJECTIVE: to explore regional primary care improvement strategies that are potentially determinants of primary care performance. DESIGN: Multiple comparative embedded case study. SETTING: Three regions in Canada: Fraser East, British Columbia; Eastern Ontario Health Unit, Ontario; Central Zone, Nova Scotia. DATA SOURCES: (1) In-depth interviews with purposively selected key informants (eg, primary care decision-makers, physician leads, regulatory agencies) and focus groups with patients and clinicians (n=68 participants) and (2) published and grey literature (n=205 documents). OUTCOME MEASURES: Variations in spread and uptake of primary care improvement strategies across the three study regions. NVivo (V.11) was used to manage data and perform content analysis to identify categories within and across cases. The coding structure was developed by researchers through iterative collaboration, using inductive and deductive processes. RESULTS: Six overarching primary care improvement strategies, differing in focus and spread, were implemented across the three study regions: interprofessional team-based approaches, provider skill mix expansion, physician groups and networks, information systems, remuneration and performance measurement and reporting infrastructure. CONCLUSION: the addition of information on regional improvement strategies to primary care performance reports could add important contextual insights into primary care performance results. This could help identify possible drivers of reported performance outcomes and levers for change in practice, regional and system-level settings.

BACKGROUND: NHS policy encourages general practices to introduce alternatives to the face-to-face consultation, such as telephone, email, e-consultation systems, or internet video. Most have been slow to adopt these, citing concerns about workload. This project builds on previous research by focusing on the experiences of patients and practitioners who have used one or more of these alternatives. AIM: to understand how, under what conditions, for which patients, and in what ways, alternatives to face-to-face consultations present benefits and challenges to patients and practitioners in general practice. DESIGN AND SETTING: Focused ethnographic case studies took place in eight UK general practices between June 2015 and March 2016. METHOD: Non-participant observation, informal conversations with staff, and semi-structured interviews with staff and patients were conducted. Practice documents and protocols were reviewed. Data were analysed through charting and the 'one sheet of paper' mind-map method to identify the line of argument in each thematic report. RESULTS: Case study practices had different rationales for offering alternatives to the face-to-face consultation. Beliefs varied about which patients and health issues were suitable. Co-workers were often unaware of each other's practice; for example, practice policies for use of e-consultations systems with patients were not known about or followed. Patients reported benefits including convenience and access. Staff and some patients regarded the face-to-face consultation as the ideal. CONCLUSION: Experience of implementing alternatives to the face-to-face consultation suggests that changes in patient access and staff workload may be both modest and gradual. Practices planning to implement them should consider carefully their reasons for doing so and involve the whole practice team.

BACKGROUND: Around 17% of people attending UK cardiac rehabilitation programmes have depression. Optimising psychological wellbeing is a rehabilitation goal, but provision of psychological care is limited. We developed and piloted an Enhanced Psychological Care (EPC) intervention embedded within cardiac rehabilitation, aiming to test key areas of uncertainty to inform the design of a definitive randomised controlled trial (RCT) and economic evaluation. METHODS: an external pilot randomised controlled trial (RCT) randomised eight cardiac rehabilitation teams (clusters) to either usual care of cardiac rehabilitation provision (UC), or EPC in addition to UC. EPC comprised mental health care coordination and patient-led behavioural activation with nurse support. Adults eligible for cardiac rehabilitation following an acute coronary syndrome and identified with new-onset depressive symptoms during an initial nurse assessment were eligible. Measures were performed at baseline and 5- and 8-month follow-ups and compared between EPC and UC. Team and participant recruitment and retention rates, and participant outcomes (clinical events, depression, anxiety, health-related quality of life, patient experiences, and resource use) were assessed. RESULTS: Eight out of twenty teams were recruited and randomised. of 614 patients screened, 55 were eligible and 29 took part (5%, 95% CI 3 to 7% of those screened), with 15 patient participants cluster randomised to EPC and 14 to UC. Nurse records revealed that 8/15 participants received the maximum number of EPC sessions offered; and 4/15 received no sessions. Seven out of fifteen EPC participants were referred to another NHS psychological service compared to none in UC. We followed up 27/29 participants at 5 months and 17/21 at 8 months. The mean difference (EPC minus UC) in depressive symptoms (Beck Depression Inventory) at follow-up (adjusting for baseline score) was 1.7 (95% CI - 3.8 to 7.3; N = 26) at 5 months and 4.4 (95% CI - 1.4 to 10.2; N = 17) at 8 months. DISCUSSION: While valued by patients and nurses, organisational and workload constraints are significant barriers to EPC implementation. There remains a need to develop and test new models of psychological care within cardiac rehabilitation. Our study offers important data to inform the design of future trials of similar interventions. TRIAL REGISTRATION: ISRCTN34701576. Registered on 29 May 2014.

BACKGROUND: Depression is usually managed in primary care and antidepressants are often the first-line treatment, but only half of those treated respond to a single antidepressant. OBJECTIVES: to investigate whether or not combining mirtazapine with serotonin-noradrenaline reuptake inhibitor (SNRI) or selective serotonin reuptake inhibitor (SSRI) antidepressants results in better patient outcomes and more efficient NHS care than SNRI or SSRI therapy alone in treatment-resistant depression (TRD). DESIGN: the MIR trial was a two-parallel-group, multicentre, pragmatic, placebo-controlled randomised trial with allocation at the level of the individual. SETTING: Participants were recruited from primary care in Bristol, Exeter, Hull/York and Manchester/Keele. PARTICIPANTS: Eligible participants were aged ≥ 18 years; were taking a SSRI or a SNRI antidepressant for at least 6 weeks at an adequate dose; scored ≥ 14 points on the Beck Depression Inventory-II (BDI-II); were adherent to medication; and met the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, criteria for depression. INTERVENTIONS: Participants were randomised using a computer-generated code to either oral mirtazapine or a matched placebo, starting at a dose of 15 mg daily for 2 weeks and increasing to 30 mg daily for up to 12 months, in addition to their usual antidepressant. Participants, their general practitioners (GPs) and the research team were blind to the allocation. MAIN OUTCOME MEASURES: the primary outcome was depression symptoms at 12 weeks post randomisation compared with baseline, measured as a continuous variable using the BDI-II. Secondary outcomes (at 12, 24 and 52 weeks) included response, remission of depression, change in anxiety symptoms, adverse events (AEs), quality of life, adherence to medication, health and social care use and cost-effectiveness. Outcomes were analysed on an intention-to-treat basis. A qualitative study explored patients' views and experiences of managing depression and GPs' views on prescribing a second antidepressant. RESULTS: There were 480 patients randomised to the trial (mirtazapine and usual care, n = 241; placebo and usual care, n = 239), of whom 431 patients (89.8%) were followed up at 12 weeks. BDI-II scores at 12 weeks were lower in the mirtazapine group than the placebo group after adjustment for baseline BDI-II score and minimisation and stratification variables [difference -1.83 points, 95% confidence interval (CI) -3.92 to 0.27 points; p = 0.087]. This was smaller than the minimum clinically important difference and the CI included the null. The difference became smaller at subsequent time points (24 weeks: -0.85 points, 95% CI -3.12 to 1.43 points; 12 months: 0.17 points, 95% CI -2.13 to 2.46 points). More participants in the mirtazapine group withdrew from the trial medication, citing mild AEs (46 vs. 9 participants). CONCLUSIONS: This study did not find convincing evidence of a clinically important benefit for mirtazapine in addition to a SSRI or a SNRI antidepressant over placebo in primary care patients with TRD. There was no evidence that the addition of mirtazapine was a cost-effective use of NHS resources. GPs and patients were concerned about adding an additional antidepressant. LIMITATIONS: Voluntary unblinding for participants after the primary outcome at 12 weeks made interpretation of longer-term outcomes more difficult. FUTURE WORK: Treatment-resistant depression remains an area of important, unmet need, with limited evidence of effective treatments. Promising interventions include augmentation with atypical antipsychotics and treatment using transcranial magnetic stimulation.

BACKGROUND: Around 19% of people screened by UK cardiac rehabilitation programmes report having moderate or severe symptoms of depression. These individuals are at an increased risk of cardiac mortality and morbidity, reduced quality of life and increased use of health resources compared with their non-depressed counterparts. Maximising psychological health is a goal of cardiac rehabilitation, but psychological care is patchy. OBJECTIVE(S): to examine the feasibility and acceptability of embedding enhanced psychological care (EPC) within cardiac rehabilitation, we tested the feasibility of developing/implementing EPC and documented the key uncertainties associated with undertaking a definitive evaluation. DESIGN: a two-stage multimethods study; a feasibility study and a qualitative evaluation, followed by an external pilot cluster randomised controlled trial (RCT) with a nested qualitative study. SETTING: UK comprehensive cardiac rehabilitation teams. PARTICIPANTS: Adults eligible for cardiac rehabilitation following an acute coronary syndrome with new-onset depressive symptoms on initial nurse assessment. Patients who had received treatment for depression in the preceding 6 months were excluded. INTERVENTIONS: the EPC intervention comprised nurse-led mental health-care co-ordination and behavioural activation within cardiac rehabilitation. The comparator was usual cardiac rehabilitation care. MAIN OUTCOME MEASURES: Measures at baseline, and at the 5- (feasibility and pilot) and 8-month follow-ups (pilot only). Process measures related to cardiac team and patient recruitment, and participant retention. Outcomes included depressive symptoms, cardiac mortality and morbidity, anxiety, health-related quality of life and service resource use. Interviews explored participant and nurses' views and experiences. RESULTS: Between September 2014 and May 2015, five nurses from four teams recruited participants into the feasibility study. of the 203 patients screened, 30 were eligible and nine took part (the target was 20 participants). At interview, participants and nurses gave valuable insights into the EPC intervention design and delivery. Although acceptable, the EPC delivery was challenging for nurses (e.g. the ability to allocate sufficient time within existing workloads) and the intervention was modified accordingly. Between December 2014 and February 2015, 8 out of 20 teams approached agreed to participate in the pilot RCT [five were randomised to the EPC arm and three were randomised to the usual-care (UC) arm]. of the 614 patients screened, 55 were eligible and 29 took part (the target was 43 participants). At baseline, the trial arms were well matched for sex and ethnicity, although the EPC arm participants were younger, from more deprived areas and had higher depression scores than the UC participants. A total of 27 out of 29 participants were followed up at 5 months. Interviews with 18 participants (12 in the EPC arm and six in the UC arm) and seven nurses who delivered EPC identified that both groups acknowledged the importance of receiving psychological support embedded within routine cardiac rehabilitation. For those experiencing/delivering EPC, the intervention was broadly acceptable, albeit challenging to deliver within existing care. LIMITATIONS: Both the feasibility and the pilot studies encountered significant challenges in recruiting patients, which limited the power of the pilot study analyses. CONCLUSIONS: Cardiac rehabilitation nurses can be trained to deliver EPC. Although valued by both patients and nurses, organisational and workload constraints were significant barriers to implementation in participating teams, suggesting that future research may require a modified approach to intervention delivery within current service arrangements. We obtained important data informing definitive research regarding participant recruitment and retention, and optimal methods of data collection. FUTURE RESEARCH: Consideration should be given to the delivery of EPC by dedicated mental health practitioners, working closely with cardiac rehabilitation services.

Objective the aim of this study was to undertake a contemporary review of the impact of exercise-based cardiac rehabilitation (CR) targeted at patients with atrial fibrillation (AF). Methods We conducted searches of PubMED, EMBASE and the Cochrane Library of Controlled Trials (up until 30 November 2017) using key terms related to exercise-based CR and AF. Randomised and non-randomised controlled trials were included if they compared the effects of an exercise-based CR intervention to a no exercise or usual care control group. Meta-analyses of outcomes were conducted where appropriate. Results the nine randomised trials included 959 (483 exercise-based CR vs 476 controls) patients with various types of AF. Compared with control, pooled analysis showed no difference in all-cause mortality (risk ratio (RR) 1.08, 95% CI 0.77 to 1.53, p=0.64) following exercise-based CR. However, there were improvements in health-related quality of life (mean SF-36 mental component score (MCS): 4.00, 95% CI 0.26 to 7.74; p=0.04 and mean SF-36 physical component score: 1.82, 95% CI 0.06 to 3.59; p=0.04) and exercise capacity (mean peak VO 2 : 1.59 ml/kg/min, 95% CI 0.11 to 3.08; p=0.04; mean 6 min walk test: 46.9 m, 95% CI 26.4 to 67.4; p

OBJECTIVES: to evaluate the feasibility, acceptability and effectiveness of webGP as piloted by six general practices. METHODS: Mixed-methods evaluation, including data extraction from practice databases, general practitioner (GP) completion of case reports, patient questionnaires and staff interviews. SETTING: General practices in NHS Northern, Eastern and Western Devon Clinical Commissioning Group's area approximately 6 months after implementing webGP (February-July 2016). PARTICIPANTS: Six practices provided consultations data; 20 GPs completed case reports (regarding 61 e-consults); 81 patients completed questionnaires; 5 GPs and 5 administrators were interviewed. OUTCOME MEASURES: Attitudes and experiences of practice staff and patients regarding webGP. RESULTS: WebGP uptake during the evaluation was small, showing no discernible impact on practice workload. The completeness of cross-sectional data on consultation workload varied between practices.GPs judged 41/61 (72%) of webGP requests to require a face-to-face or telephone consultation. Introducing webGP appeared to be associated with shifts in responsibility and workload between practice staff and between practices and patients.81/231 patients completed a postal survey (35.1% response rate). E-Consulters were somewhat younger and more likely to be employed than face-to-face respondents. WebGP appeared broadly acceptable to patients regarding timeliness and quality/experience of care provided. Similar problems were presented by all respondents. Both groups appeared equally familiar with other practice online services; e-consulters were somewhat more likely to have used them.From semistructured staff interviews, it appeared that, while largely acceptable within practice, introducing e-consults had potential for adverse interactions with pre-existing practice systems. CONCLUSIONS: There is potential to assess the impact of new systems on consultation patterns by extracting routine data from practice databases. Staff and patients noticed subtle changes to responsibilities associated with online options. Greater uptake requires good communication between practice and patients, and organisation of systems to avoid conflicts and misuse. Further research is required to evaluate the full potential of webGP in managing practice workload.

BACKGROUND: Offenders frequently have substantial healthcare needs and, like many other socially marginalised groups, often receive healthcare in inverse proportion to their needs. Improved continuity of healthcare over time could contribute to addressing these needs. General Practitioners need to be able to support people with complex social and medical problems, even in systems that are not specifically designed to manage individuals with such degrees of complexity. We aimed to examine offenders' perspectives on factors that contributed to, or worked against, creating and sustaining their access to healthcare. METHODS: from a sample of 200 participants serving community or prison sentences in South West (SW) and South East (SE) England, who were interviewed about their health care experiences as part of the Care for Offenders: Continuity of Access (COCOA) study, we purposively sampled 22 participants for this sub-study, based on service use. These interviews were transcribed verbatim. A thematic analytic approach initially applied 5 a priori codes based on access and different components of continuity. Data were then examined for factors that contributed to achieving and disrupting access and continuity. RESULTS: Participants described how their own life situations and behaviours contributed to their problems in accessing healthcare and also identified barriers created by existing access arrangements. They also highlighted how some General Practitioners used their initiative and skills to 'workaround' the system, and build positive relationships with them; feeling listened to and building trust were particularly valued, as was clear communication. Limitations faced by General Practitioners included a lack of appropriate services to refer people to, where the offender patients would meet the access criteria, and disagreements regarding medication prescriptions. CONCLUSIONS: General Practitioners can make a positive contribution to supporting access to healthcare for an under-served population by facilitating more flexible and less formal access arrangements, by using their relationship skills, and by problem-solving. General Practitioners should recognise their potential to transform people's experience of healthcare whilst working in imperfect systems, particularly with vulnerable and marginalised groups who have complex medical and social needs.

Objective: to study the relationships between the different domains of quality of primary health care for the evaluation of health system performance and for informing policy decision making. Data Sources: a total of 137 quality indicators collected from 7,607 English practices between 2011 and 2012. Study Design: Cross-sectional study at the practice level. Indicators were allocated to subdomains of processes of care (“quality assurance,” “education and training,” “medicine management,” “access,” “clinical management,” and “patient-centered care”), health outcomes (“intermediate outcomes” and “patient-reported health status”), and patient satisfaction. The relationships between the subdomains were hypothesized in a conceptual model and subsequently tested using structural equation modeling. Principal Findings: the model supported two independent paths. In the first path, “access” was associated with “patient-centered care” (β = 0.63), which in turn was strongly associated with “patient satisfaction” (β = 0.88). In the second path, “education and training” was associated with “clinical management” (β = 0.32), which in turn was associated with “intermediate outcomes” (β = 0.69). “Patient-reported health status” was weakly associated with “patient-centered care” (β = −0.05) and “patient satisfaction” (β = 0.09), and not associated with “clinical management” or “intermediate outcomes.”. Conclusions: This is the first empirical model to simultaneously provide evidence on the independence of intermediate health care outcomes, patient satisfaction, and health status. The explanatory paths via technical quality clinical management and patient centeredness offer specific opportunities for the development of quality improvement initiatives.

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: to explore the effectiveness of interventions delivered with the aim of involving older patients with multimorbidity in decision-making about their health care during primary care consultations.

BACKGROUND: Non-response to antidepressant medication is common in primary care. Little is known about how GPs manage patients with depression that does not respond to medication. AIM: to describe usual care for primary care patients with treatment-resistant depression (TRD). DESIGN AND SETTING: Mixed-methods study using data from a UK primary care multicentre randomised controlled trial. METHOD: in total, 235 patients with TRD randomised to continue with usual GP care were followed up at 3-month intervals for a year. Self-report data were collected on antidepressant medication, number of GP visits, and other treatments received. In addition, 14 semi-structured face-to-face interviews were conducted with a purposive sample after the 6-month follow-up and analysed thematically. RESULTS: Most patients continued on the same dose of a single antidepressant between baseline and 3 months (n = 147/186 at 3 months, 79% (95% confidence interval [CI] = 73 to 85%)). Figures were similar for later follow-ups (for example, 9-12 months: 72% (95% CI = 63 to 79%). Medication changes (increasing dose; switching to a different antidepressant; adding a second antidepressant) were uncommon. Participants described usual care mainly as taking antidepressants, with consultations focused on other (physical) health concerns. Few accessed other treatments or were referred to secondary care. CONCLUSION: Usual care in patients with TRD mainly entailed taking antidepressants, and medication changes were uncommon. The high prevalence of physical and psychological comorbidity means that, when these patients consult, their depression may not be discussed. Strategies are needed to ensure the active management of this large group of patients whose depression does not respond to antidepressant medication.

INTRODUCTION: Physical activity is recommended for improving health among people with common chronic conditions such as obesity, diabetes, hypertension, osteoarthritis and low mood. One approach to promote physical activity is via primary care exercise referral schemes (ERS). However, there is limited support for the effectiveness of ERS for increasing long-term physical activity and additional interventions are needed to help patients overcome barriers to ERS uptake and adherence.This study aims to determine whether augmenting usual ERS with web-based behavioural support, based on the LifeGuide platform, will increase long-term physical activity for patients with chronic physical and mental health conditions, and is cost-effective. METHODS AND ANALYSIS: a multicentre parallel two-group randomised controlled trial with 1:1 individual allocation to usual ERS alone (control) or usual ERS plus web-based behavioural support (intervention) with parallel economic and mixed methods process evaluations. Participants are low active adults with obesity, diabetes, hypertension, osteoarthritis or a history of depression, referred to an ERS from primary care in the UK.The primary outcome measure is the number of minutes of moderate-to-vigorous physical activity (MVPA) in ≥10 min bouts measured by accelerometer over 1 week at 12 months.We plan to recruit 413 participants, with 88% power at a two-sided alpha of 5%, assuming 20% attrition, to demonstrate a between-group difference of 36-39 min of MVPA per week at 12 months. An improvement of this magnitude represents an important change in physical activity, particularly for inactive participants with chronic conditions. ETHICS AND DISSEMINATION: Approved by North West Preston NHS Research Ethics Committee (15/NW/0347). Dissemination will include publication of findings for the stated outcomes, parallel process evaluation and economic evaluation in peer-reviewed journals.Results will be disseminated to ERS services, primary healthcare providers and trial participants. TRIAL REGISTRATION NUMBER: ISRCTN15644451; Pre-results.

INTRODUCTION: Multisource feedback is a questionnaire-based assessment tool that provides physicians with data about workplace behaviors and may combine numeric and narrative (free-text) comments. Little attention has been paid to wording of requests for comments, potentially limiting its utility to support physician performance. This study tested the phrasing of two different sets of questions. METHODS: Two sets of questions were tested with family physicians, medical and surgical specialists, and their medical colleague and coworker respondents. One set asked respondents to identify one thing the participant physician does well and one thing the physician could target for action. Set 2 questions asked what does the physician do well and what might the physician do to enhance practice. Resulting free-text comments provided by respondents were coded for polarity (positive, neutral, or negative), specificity (precision and detail), actionability (ability to use the feedback to direct future activity), and CanMEDS roles (competencies) and analyzed descriptively. RESULTS: Data for 222 physicians (111 physicians per set) were analyzed. A total of 1824 comments (8.2/physician) were submitted, with more comments from coworkers than medical colleagues. Set 1 yielded more comments and were more likely to be positive, semi specific, and very actionable than set 2. However, set 2 generated more very specific comments. Comments covered all CanMEDS roles with more comments for collaborator and leader roles. DISCUSSION: the wording of questions inviting free-text responses influences the volume and nature of the comments provided. Individuals designing multisource feedback tools should carefully consider wording of items soliciting narrative responses.

PURPOSE: Multimorbidity is associated with adverse outcomes, yet research on the determinants of its incidence is lacking. We investigated which sociodemographic, health, and individual lifestyle (eg, physical activity, smoking behavior, body mass index) characteristics predict new cases of multimorbidity. METHODS: We used data from 4,564 participants aged 50 years and older in the English Longitudinal Study of Aging that included a 10-year follow-up period. Discrete time-to-event (complementary log-log) models were constructed for exploring the associations of baseline characteristics with outcomes between 2002-2003 and 2012-2013 separately for participants with no initial conditions (n = 1,377) developing multimorbidity, any increase in conditions within 10 years regardless of initial conditions, and the impact of individual conditions on incident multimorbidity. RESULTS: the risks of developing multimorbidity were positively associated with age, and they were greater for the least wealthy, for participants who were obese, and for those who reported the lowest levels of physical activity or an external locus of control (believing that life events are outside of one's control) for all groups regardless of baseline conditions (all linear trends

Patient evaluations of physician communication are widely used, but we know little about how these relate to professionally agreed norms of communication quality. We report an investigation into the association between patient assessments of communication quality and an observer-rated measure of communication competence. Consent was obtained to video record consultations with Family Practitioners in England, following which patients rated the physician's communication skills. A sample of consultation videos was subsequently evaluated by trained clinical raters using an instrument derived from the Calgary-Cambridge guide to the medical interview. Consultations scored highly for communication by clinical raters were also scored highly by patients. However, when clinical raters judged communication to be of lower quality, patient scores ranged from "poor" to "very good." Some patients may be inhibited from rating poor communication negatively. Patient evaluations can be useful for measuring relative performance of physicians' communication skills, but absolute scores should be interpreted with caution.

BACKGROUND: the receptionist is pivotal to the smooth running of general practice in the UK, communicating with patients and booking appointments. AIM: the authors aimed to explore the role of the receptionist in the implementation of new approaches to consultations in primary care. DESIGN AND SETTING: the authors conducted a team-based focused ethnography. Three researchers observed eight general practices across England and Scotland between June 2015 and May 2016. METHOD: Interviews were conducted with 39 patients and 45 staff in the practices, all of which had adopted one or more methods (telephone, email, e-consultation, or internet video) for providing an alternative to face-to-face consultation. RESULTS: Receptionists have a key role in facilitating patient awareness regarding new approaches to consultations in primary care, while at the same time ensuring that patients receive a consultation appropriate to their needs. In this study, receptionists' involvement in implementation and planning for the introduction of alternative approaches to face-to-face consultations was minimal, despite the expectation that they would be involved in delivery. CONCLUSION: a shared understanding within practices of the potential difficulties and extra work that might ensue for reception staff was lacking. This might contribute to the low uptake by patients of potentially important innovations in service delivery. Involvement of the wider practice team in planning and piloting changes, supporting team members through service reconfiguration, and providing an opportunity to discuss and contribute to modifications of any new system would ensure that reception staff are suitably prepared to support the introduction of a new approach to consultations.

PURPOSE: to examine how family physicians', patients', and trained clinical raters' assessments of physician-patient communication compare by analysis of individual appointments. METHODS: Analysis of survey data from patients attending face-to-face appointments with 45 family physicians at 13 practices in England. Immediately post-appointment, patients and physicians independently completed a questionnaire including 7 items assessing communication quality. A sample of videotaped appointments was assessed by trained clinical raters, using the same 7 communication items. Patient, physician, and rater communication scores were compared using correlation coefficients. RESULTS: Included were 503 physician-patient pairs; of those, 55 appointments were also evaluated by trained clinical raters. Physicians scored themselves, on average, lower than patients (mean physician score 74.5; mean patient score 94.4); 63.4% (319) of patient-reported scores were the maximum of 100. The mean of rater scores from 55 appointments was 57.3. There was a near-zero correlation coefficient between physician-reported and patient-reported communication scores (0.009, P =. 854), and between physician-reported and trained rater-reported communication scores (-0.006, P =. 69). There was a moderate and statistically significant association, however, between patient and trained-rater scores (0.35, P =. 042). CONCLUSIONS: the lack of correlation between physician scores and those of others indicates that physicians' perceptions of good communication during their appointments may differ from those of external peer raters and patients. Physicians may not be aware of how patients experience their communication practices; peer assessment of communication skills is an important approach in identifying areas for improvement.

BackgroundThere is international interest in the potential role of different forms of communication technology to provide an alternative to face-to-face consultations in health care. There has been considerable rhetoric about the need for general practices to offer consultations by telephone, e-mail or internet video. However, little is understood about how, under what conditions, for which patients and in what ways these approaches may offer benefits to patients and practitioners in general practice.ObjectivesOur objectives were to review existing evidence about alternatives to face-to-face consultation; conduct a scoping exercise to identify the ways in which general practices currently provide these alternatives; recruit eight general practices as case studies for focused ethnographic research, exploring how practice context, patient characteristics, type of technology and the purpose of the consultation interact to determine the impact of these alternatives; and synthesise the findings in order to develop a website resource about the implementation of alternatives to face-to-face consultations and a framework for subsequent evaluation.DesignMixed-methods case study.SettingGeneral practices in England and Scotland with varied experience of implementing alternatives to face-to-face consultations.ParticipantsPatients and practice staff.InterventionsAlternatives to face-to-face consultations include telephone consultations, e-mail, e-consultations and internet video.Main outcome measuresHow context influenced the implementation and impact of alternatives to the face-to-face consultation; the rationale for practices to introduce alternatives; the use of different forms of consultation by different patient groups; and the intended benefits/outcomes.Review methodsThe conceptual review used an approach informed by realist review, a method for synthesising research evidence regarding complex interventions.ResultsAlternatives to the face-to-face consultation are not in mainstream use in general practice, with low uptake in our case study practices. We identified the underlying rationales for the use of these alternatives and have shown that different stakeholders have different perspectives on what they hope to achieve through the use of alternatives to the face-to-face consultation. Through the observation of real-life use of different forms of alternative, we have a clearer understanding of how, under what circumstances and for which patients alternatives might have a range of intended benefits and potential unintended adverse consequences. We have also developed a framework for future evaluation.LimitationsThe low uptake of alternatives to the face-to-face consultation means that our research participants might be deemed to be early adopters. The case study approach provides an in-depth examination of a small number of sites, each using alternatives in different ways. The findings are therefore hypothesis-generating, rather than hypothesis-testing.ConclusionsThe current low uptake of alternatives, lack of clarity about purpose and limited evidence of benefit may be at odds with current policy, which encourages the use of alternatives. We have highlighted key issues for practices and policy-makers to consider and have made recommendations about priorities for further research to be conducted, before or alongside the future roll-out of alternatives to the face-to-face consultation, such as telephone consulting, e-consultation, e-mail and video consulting.Future workWe have synthesised our findings to develop a framework and recommendations about future evaluation of the use of alternatives to face-to-face consultations.Funding detailsThe National Institute for Health Research Health Services and Delivery Research programme.

Objectives to examine patient consultation preferences for seeing or speaking to a general practitioner (GP) or nurse; to estimate associations between patient-reported experiences and the type of consultation patients actually received (phone or face-to-face, GP or nurse). Design Secondary analysis of data from the 2013 to 2014 General Practice Patient Survey. Setting and participants 870 085 patients from 8005 English general practices. Outcomes Patient ratings of communication and 'trust and confidence' with the clinician they saw. Results 77.7% of patients reported wanting to see or speak to a GP, while 14.5% reported asking to see or speak to a nurse the last time they tried to make an appointment (weighted percentages). Being unable to see or speak to the practitioner type of the patients' choice was associated with lower ratings of trust and confidence and patient-rated communication. Smaller differences were found if patients wanted a face-to-face consultation and received a phone consultation instead. The greatest difference was for patients who asked to see a GP and instead spoke to a nurse for whom the adjusted mean difference in confidence and trust compared with those who wanted to see a nurse and did see a nurse was 15.8 points (95% CI -17.6 to -14.0) for confidence and trust in the practitioner and -10.5 points (95% CI -11.7 to -9.3) for net communication score, both on a 0-100 scale. Conclusions Patients' evaluation of their care is worse if they do not receive the type of consultation they expect, especially if they prefer a doctor but are unable to see one. New models of care should consider the potential unintended consequences for patient experience of the widespread introduction of multidisciplinary teams in general practice.

OBJECTIVE: to identify factors influencing general practitioners' (GPs') decisions about whether or not to remain in direct patient care in general practice and what might help to retain them in that role. DESIGN: Qualitative, in-depth, individual interviews exploring factors related to GPs leaving, remaining in and returning to direct patient care. SETTING: South West England, UK. PARTICIPANTS: 41 GPs: 7 retired; 8 intending to take early retirement; 11 who were on or intending to take a career break; 9 aged under 50 years who had left or were intending to leave direct patient care and 6 who were not intending to leave or to take a career break. Plus 19 stakeholders from a range of primary care-related professional organisations and roles. RESULTS: Reasons for leaving direct patient care were complex and based on a range of job-related and individual factors. Three key themes underpinned the interviewed GPs' thinking and rationale: issues relating to their personal and professional identity and the perceived value of general practice-based care within the healthcare system; concerns regarding fear and risk, for example, in respect of medical litigation and managing administrative challenges within the context of increasingly complex care pathways and environments; and issues around choice and volition in respect of personal social, financial, domestic and professional considerations. These themes provide increased understanding of the lived experiences of working in today's National Health Service for this group of GPs. CONCLUSION: Future policies and strategies aimed at retaining GPs in direct patient care should clarify the role and expectations of general practice and align with GPs' perception of their own roles and identity; demonstrate to GPs that they are valued and listened to in planning delivery of the UK healthcare; target GPs' concerns regarding fear and risk, seeking to reduce these to manageable levels and give GPs viable options to support them to remain in direct patient care.

INTRODUCTION: Individual cohort studies in various populations and study-level meta-analyses have shown interarm differences (IAD) in blood pressure to be associated with increased cardiovascular and all-cause mortality. However, key questions remain, such as follows: (1) What is the additional contribution of IAD to prognostic risk estimation for cardiovascular and all-cause mortality? (2) What is the minimum cut-off value for IAD that defines elevated risk? (3) is there a prognostic value of IAD and do different methods of IAD measurement impact on the prognostic value of IAD? We aim to address these questions by conducting an individual patient data (IPD) meta-analysis. METHODS AND ANALYSIS: This study will identify prospective cohort studies that measured blood pressure in both arms during recruitment, and invite authors to contribute IPD datasets to this collaboration. All patient data received will be combined into a single dataset. Using one-stage meta-analysis, we will undertake multivariable time-to-event regression modelling, with the aim of developing a new prognostic model for cardiovascular risk estimation that includes IAD. We will explore variations in risk contribution of IAD across predefined population subgroups (eg, hypertensives, diabetics), establish the lower limit of IAD that is associated with additional cardiovascular risk and assess the impact of different methods of IAD measurement on risk prediction. ETHICS AND DISSEMINATION: This study will not include any patient identifiable data. Included datasets will already have ethical approval and consent from their sponsors. Findings will be presented to international conferences and published in peer reviewed journals, and we have a comprehensive dissemination strategy in place with integrated patient and public involvement.

Focused ethnography is an applied and pragmatic form of ethnography that explores a specific social phenomenon as it occurs in everyday life. Based on the literature a problem-focused research question is formulated before the data collection. The data generation process targets key informants and situations so that relevant results on the pre-defined topic can be obtained within a relatively short time-span. As part of a theory based evaluation of alternative forms of consultation (such as video, phone and email) in primary care we used the focused ethnographic method in a multisite study in general practice across the UK. To date there is a gap in the literature on using focused ethnography in healthcare research.The aim of the paper is to build on the various methodological approaches in health services research by presenting the challenges and benefits we encountered whilst conducing a focused ethnography in British primary care. Our considerations are clustered under three headings: constructing a shared understanding, dividing the tasks within the team, and the functioning of the focused ethnographers within the broader multi-disciplinary team.As a result of using this approach we experienced several advantages, like the ability to collect focused data in several settings simultaneously within in a short time-span. Also, the sharing of experiences and interpretations between the researchers contributed to a more holistic understanding of the research topic. However, mechanisms need to be in place to facilitate and synthesise the observations, guide the analysis, and to ensure that all researchers feel engaged. Reflection, trust and flexibility among the team members were crucial to successfully adopt a team focused ethnographic approach. When used for policy focussed applied healthcare research a team-based multi-sited focused ethnography can uncover practices and understandings that would not be apparent through surveys or interviews alone. If conducted with care, it can provide timely findings within the fast moving context of healthcare policy and research.

BACKGROUND: Patient experience surveys are increasingly important in the measurement of, and attempts to improve, health-care quality. To date, little research has focused upon doctors' attitudes to surveys which give them personalized feedback. AIM: This paper explores doctors' perceptions of patient experience surveys in primary and secondary care settings in order to deepen understandings of how doctors view the plausibility of such surveys. DESIGN, SETTING AND PARTICIPANTS: We conducted a qualitative study with doctors in two regions of England, involving in-depth semi-structured interviews with doctors working in primary care (n = 21) and secondary care (n = 20) settings. The doctors in both settings had recently received individualized feedback from patient experience surveys. FINDINGS: Doctors in both settings express strong personal commitments to incorporating patient feedback in quality improvement efforts. However, they also concurrently express strong negative views about the credibility of survey findings and patients' motivations and competence in providing feedback. Thus, individual doctors demonstrate contradictory views regarding the plausibility of patient surveys, leading to complex, varied and on balance negative engagements with patient feedback. DISCUSSION: Doctors' contradictory views towards patient experience surveys are likely to limit the impact of such surveys in quality improvement initiatives in primary and secondary care. We highlight the need for 'sensegiving' initiatives (i.e. attempts to influence perceptions by communicating particular ideas, narratives and visions) to engage with doctors regarding the plausibility of patient experience surveys. CONCLUSION: This study highlights the importance of engaging with doctors' views about patient experience surveys when developing quality improvement initiatives.

Background: Cognitive Behavioural Therapy (CBT) aims to teach people skills to help them self-manage their depression. Trial evidence shows that CBT is an effective treatment for depression and individuals may experience benefits long-term. However, there is little research about individuals' continued use of CBT skills once treatment has finished. Aims: to explore whether individuals who had attended at least 12 sessions of CBT continued to use and value the CBT skills they had learnt during therapy. Method: Semi-structured interviews were held with participants from the CoBalT trial who had received CBT, approximately 4 years earlier. Interviews were audio-recorded, transcribed and analysed thematically. Results: 20 participants were interviewed. Analysis of the interviews suggested that individuals who viewed CBT as a learning process, at the time of treatment, recalled and used specific skills to manage their depression once treatment had finished. In contrast, individuals who viewed CBT only as an opportunity to talk about their problems did not appear to utilize any of the CBT skills they had been taught and reported struggling to manage their depression once treatment had ended. Conclusions: Our findings suggest individuals may value and use CBT skills if they engage with CBT as a learning opportunity at the time of treatment. Our findings underline the importance of the educational model in CBT and the need to emphasize this to individuals receiving treatment.

BACKGROUND: Guidelines recommend 10-day treatment courses for acute sore throat, but shorter courses may be used in practice. AIM: to determine whether antibiotic duration predicts adverse outcome of acute sore throat in adults in routine care. DESIGN AND SETTING: a secondary analysis of the DESCARTE (Decision rule for the Symptoms and Complications of Acute Red Throat in Everyday practice) prospective cohort study of 12 829 adults presenting in UK general practice with acute sore throat. METHOD: a brief clinical proforma was used to collect symptom severity and examination findings at presentation. Outcomes were collected by notes review, a sample also completed a symptom diary. The primary outcome was re-consultation with new/non-resolving symptoms within 1 month. The secondary outcome was 'global' poorer symptom control (longer than the median duration or higher than median severity). RESULTS: Antibiotics were prescribed for 62% (7872/12 677) of participants. The most commonly prescribed antibiotic was phenoxymethylpenicillin (76%, 5656/7474) and prescription durations were largely for 5 (20%), 7 (57%), or 10 (22%) days. Compared with 5-day courses, those receiving longer courses were less likely to re-consult with new or non-resolving symptoms (5 days 15.3%, 7 days 13.9%, 10 days 12.2%, 7-day course adjusted risk ratio (RR) 0.92 [95% confidence interval [CI] = 0.76 to 1.11] and 10-days RR 0.86 [95% CI = 0.59 to 1.23]) but these differences did not reach statistical significance. CONCLUSION: in adults prescribed antibiotics for sore throat, the authors cannot rule out a small advantage in terms of reduced re-consultation for a 10-day course of penicillin, but the effect is likely to be small.

OBJECTIVE: to examine concordance between responses to patient experience survey items evaluating doctors' interpersonal skills, and subsequent patient interview accounts of their experiences of care. DESIGN: Mixed methods study integrating data from patient questionnaires completed immediately after a video-recorded face-to-face consultation with a general practitioner (GP) and subsequent interviews with the same patients which included playback of the recording. SETTING: 12 general practices in rural, urban and inner city locations in six areas in England. PARTICIPANTS: 50 patients (66% female, aged 19-96�
years) consulting face-to-face with 32 participating GPs. MAIN OUTCOME MEASURES: Positive responses to interpersonal skills items in a postconsultation questionnaire ('good' and 'very good') were compared with experiences reported during subsequent video elicitation interview (categorised as positive, negative or neutral by independent clinical raters) when reviewing that aspect of care. RESULTS: We extracted 230 textual statements from 50 interview transcripts which related to the evaluation of GPs' interpersonal skills. Raters classified 70.9% (n=163) of these statements as positive, 19.6% (n=45) neutral and 9.6% (n=22) negative. Comments made by individual patients during interviews did not always express the same sentiment as their responses to the questionnaire. Where questionnaire responses indicated that interpersonal skills were 'very good', 84.6% of interview statements concerning that item were classified as positive. However, where patients rated interpersonal skills as 'good', only 41.9% of interview statements were classified as positive, and 18.9% as negative. CONCLUSIONS: Positive responses on patient experience questionnaires can mask important negative experiences which patients describe in subsequent interviews. The interpretation of absolute patient experience scores in feedback and public reporting should be done with caution, and clinicians should not be complacent following receipt of 'good' feedback. Relative scores are more easily interpretable when used to compare the performance of providers.

OBJECTIVE: to explore patients' and nurses' views on the feasibility and acceptability of providing psychological care within cardiac rehabilitation services. DESIGN: In-depth interviews analysed thematically. PARTICIPANTS: 18 patients and 7 cardiac nurses taking part in a pilot trial (CADENCE) of an enhanced psychological care intervention delivered within cardiac rehabilitation programmes by nurses to patients with symptoms of depression. SETTING: Cardiac services based in the South West of England and the East Midlands, UK. RESULTS: Patients and nurses viewed psychological support as central to good cardiac rehabilitation. Patients' accounts highlighted the significant and immediate adverse effect a cardiac event can have on an individual's mental well-being. They also showed that patients valued nurses attending to both their mental and physical health, and felt this was essential to their overall recovery. Nurses were committed to providing psychological support, believed it benefited patients, and advocated for this support to be delivered within cardiac rehabilitation programmes rather than within a parallel healthcare service. However, nurses were time-constrained and found it challenging to provide psychological care within their existing workloads. CONCLUSIONS: Both patients and nurses highly value psychological support being delivered within cardiac rehabilitation programmes but resource constraints raise barriers to implementation. Consideration, therefore, should be given to alternative forms of delivery which do not rely solely on nurses to enable patients to receive psychological support during cardiac rehabilitation. TRIAL REGISTRATION NUMBER: ISCTRN34701576.

BACKGROUND: There is growing interest in real-time feedback (RTF), which involves collecting and summarizing information about patient experience at the point of care with the aim of informing service improvement. OBJECTIVE: to investigate the feasibility and acceptability of RTF in UK general practice. DESIGN: Exploratory randomized trial. SETTING/PARTICIPANTS: Ten general practices in south-west England and Cambridgeshire. All patients attending surgeries were eligible to provide RTF. INTERVENTION: Touch screens were installed in waiting areas for 12 weeks with practice staff responsible for encouraging patients to provide RTF. All practices received fortnightly feedback summaries. Four teams attended a facilitated reflection session. OUTCOMES: RTF 'response rates' among consulting patients were estimated, and the representativeness of touch screen users were assessed. The frequency of staff-patient interactions about RTF (direct observation) and patient views of RTF (exit survey) were summarized. Associated costs were collated. RESULTS: About 2.5% consulting patients provided RTF (range 0.7-8.0% across practices), representing a mean of 194 responses per practice. Patients aged above 65 were under-represented among touch screen users. Receptionists rarely encouraged RTF but, when this did occur, 60% patients participated. Patients were largely positive about RTF but identified some barriers. Costs per practice for the twelve-week period ranged from £1125 (unfacilitated team-level feedback) to £1887 (facilitated team ± practitioner-level feedback). The main cost was the provision of touch screens. CONCLUSIONS: Response rates for RTF were lower than those of other survey modes, although the numbers of patients providing feedback to each practice were comparable to those achieved in the English national GP patient survey. More patients might engage with RTF if the opportunity were consistently highlighted to them.

BACKGROUND: UK general practice is experiencing a workload crisis. Pharmacists are the third largest healthcare profession in the UK; however, their skills are a currently underutilised and potentially highly valuable resource for primary health care. This study forms part of the evaluation of an innovative training programme for pharmacists who are interested in extended roles in primary care, advocated by a UK collaborative '10-point GP workforce action plan'. AIM: to explore pharmacists' perceptions of primary care roles including the potential for greater integration of their profession into general practice. DESIGN AND SETTING: a qualitative interview study in UK primary care carried out between October 2015 and July 2016. METHOD: Pharmacists were purposively sampled by level of experience, geographical location, and type of workplace. Two confidential semi-structured telephone interviews were conducted - one before and one after the training programme. A constant comparative, inductive approach to thematic analysis was used. RESULTS: Sixteen participants were interviewed. The themes related to: initial expectations of the general practice role, varying by participants' experience of primary care; the influence of the training course with respect to managing uncertainty, critical appraisal skills, and confidence for the role; and predictions for the future of this role. CONCLUSION: There is enthusiasm and willingness among pharmacists for new, extended roles in primary care, which could effectively relieve GP workload pressures. A definition of the role, with examples of the knowledge, skills, and attributes required, should be made available to pharmacists, primary care teams, and the public. Training should include clinical skills teaching, set in context through exposure to general practice, and delivered motivationally by primary care practitioners.

OBJECTIVE: Given recent concerns regarding general practitioner (GP) workforce capacity, we aimed to describe GPs' career intentions, especially those which might impact on GP workforce availability over the next 5 years. DESIGN: Census survey, conducted between April and June 2016 using postal and online responses , of all GPs on the National Health Service performers list and eligible to practise in primary care. Two reminders were used as necessary. SETTING: South West England (population 3.5  million), a region with low overall socioeconomic deprivation. PARTICIPANTS: Eligible GPs were 2248 out of 3370 (67 % response rate). MAIN OUTCOME MEASURES: Reported likelihood of permanently leaving or reducing hours spent in direct patient care or of taking a career break within the next 5 years and present morale weighted for non-response. RESULTS: Responders included 217 7 GPs engaged in patient care. of these, 863 (37% weighted, 95%  CI 35 % to 39 %) reported a high likelihood of quitting direct patient care within the next 5 years. Overall, 1535 (70% weighted, 95%  CI 68 % to 72 %) respondents reported a career intention that would negatively impact GP workforce capacity over the next 5 years, through permanently leaving or reducing hours spent in direct patient care, or through taking a career break. GP age was an important predictor of career intentions; sharp increases in the proportion of GPs intending to quit patient care were evident from 52 years. Only 305 (14% weighted, 95%  CI 13 % to 16 %) reported high morale, while 1195 ( 54 % weighted, 95%  CI 52 % to 56 %) reported low morale. Low morale was particularly common among GP partners. Current morale strongly predicted GPs' career intentions; those with very low morale were particularly likely to report intentions to quit patient care or to take a career break. CONCLUSIONS: a substantial majority of GPs in South West England report low morale. Many are considering career intentions which, if implemented, would adversely impact GP workforce capacity within a short time period. STUDY REGISTRATION: NIHR HS&DR - 14/196/02, UKCRN ID 20700.

BACKGROUND: a delayed or 'just in case' prescription has been identified as having potential to reduce antibiotic use in sore throat. AIM: to determine the symptomatic outcome of acute sore throat in adults according to antibiotic prescription strategy in routine care. DESIGN AND SETTING: a secondary analysis of the DESCARTE (Decision rule for the Symptoms and Complications of Acute Red Throat in Everyday practice) prospective cohort study comprising adults aged ≥16 years presenting with acute sore throat (≤2 weeks' duration) managed with treatment as usual in primary care in the UK. METHOD: a random sample of 2876 people from the full cohort were requested to complete a symptom diary. A brief clinical proforma was used to collect symptom severity and examination findings at presentation. Outcome details were collected by notes review and a detailed symptom diary. The primary outcome was poorer 'global' symptom control (defined as longer than the median duration or higher than median symptom severity). Analyses controlled for confounding by indication (propensity to prescribe antibiotics). RESULTS: a total of 1629/2876 (57%) of those requested returned a symptom diary, of whom 1512 had information on prescribing strategy. The proportion with poorer global symptom control was greater in those not prescribed antibiotics 398/587 (68%) compared with those prescribed immediate antibiotics 441/728 (61%) or delayed antibiotic prescription 116/197 59%); adjusted risk ratio (RR) (95% confidence intervals [CI]): immediate RR 0.87 (95% CI = 0.70 to 0.96), P = 0.006; delayed RR 0.88 (95% CI = 0.78 to 1.00), P = 0.042. CONCLUSION: in the routine care of adults with sore throat, a delayed antibiotic strategy confers similar symptomatic benefits to immediate antibiotics compared with no antibiotics. If a decision is made to prescribe an antibiotic, a delayed antibiotic strategy is likely to yield similar symptomatic benefit to immediate antibiotics.

Policy makers should reconsider their unequivocal support for these systems

BACKGROUND: Previous surveys identified a shift to nurse-led care in hypertension in 2010. In 2011 the National Institute for Health and Care Excellence (NICE) recommended ambulatory (ABPM) or home (HBPM) blood pressure (BP) monitoring for diagnosis of hypertension. AIM: to survey the organisation of hypertension care in 2016 to identify changes, and to assess uptake of NICE diagnostic guidelines. DESIGN AND SETTING: Questionnaires were distributed to all 305 general practices in South West England. METHOD: Responses were compared with previous rounds (2007 and 2010). Data from the 2015 Quality and Outcomes Framework (QOF) were used to compare responders with non-responders, and to explore associations of care organisation with QOF achievement. RESULTS: One-hundred-and-seventeen practices (38%) responded. Responders had larger list sizes and greater achievement of the QOF target BP ≤150/90 mmHg. Healthcare assistants (HCAs) now monitor BP in 70% of practices, compared with 37% in 2010 and 19% in 2007 (P

Reaching a decision about whether and when to visit the doctor can be a difficult process for the patient. An early visit may cause the doctor to wonder why the patient chose to consult when the disease was self-limiting and symptoms would have settled without medical input. A late visit may cause the doctor to express dismay that the patient waited so long before consulting. In the UK primary care context of constrained resources and government calls for cautious healthcare spending, there is all the more pressure on both doctor and patient to meet only when necessary. A tendency on the part of health professionals to judge patients' decisions to consult as appropriate or not is already described. What is less well explored is the patient's experience of such judgment. Drawing on data from 52 video-elicitation interviews conducted in the English primary care setting, the present paper examines how patients seek to legitimise their decision to consult, and their struggles in doing so. The concern over wasting the doctor's time is expressed repeatedly through patients' narratives. Referring to the sociological literature, the history of 'trivia' in defining the role of general practice is discussed, and current public discourses seeking to assist the patient in developing appropriate consulting behaviour are considered and problematised. Whilst the patient is expected to have sufficient insight to inform timely consulting behaviour, it becomes clear that any attempt on the part of doctor or patient to define legitimate help-seeking is in fact elusive. Despite this, a significant moral dimension to what is deemed appropriate consulting by doctors and patients remains. The notion of candidacy is suggested as a suitable framework and way forward for encompassing these struggles to negotiate eligibility for medical time.

INTRODUCTION: Economically disadvantaged smokers not intending to stop may benefit from interventions aimed at reducing their smoking. This study assessed the effects of a behavioral intervention promoting an increase in physical activity versus usual care in a pilot randomized controlled trial. METHODS: Disadvantaged smokers who wanted to reduce but not quit were randomized to either a counseling intervention of up to 12 weeks to support smoking reduction and increased physical activity (n = 49) or usual care (n = 50). Data at 16 weeks were collected for various smoking and physical activity outcomes. Primary analyses consisted of an intention to treat analysis based on complete case data. Secondary analyses explored the impact of handling missing data. RESULTS: Compared with controls, intervention smokers were more likely to initiate a quit attempt (36 vs. 10%; odds ratio 5.05, [95% CI: 1.10; 23.15]), and a greater proportion achieved at least 50% reduction in cigarettes smoked (63 vs. 32%; 4.21 [1.32; 13.39]). Postquit abstinence measured by exhaled carbon monoxide at 4-week follow-up showed promising differences between groups (23% vs. 6%; 4.91 [0.80; 30.24]). No benefit of intervention on physical activity was found. Secondary analyses suggested that the standard missing data assumption of "missing" being equivalent to "smoking" may be conservative resulting in a reduced intervention effect. CONCLUSIONS: a smoking reduction intervention for economically disadvantaged smokers which involved personal support to increase physical activity appears to be more effective than usual care in achieving reduction and may promote cessation. The effect does not appear to be influenced by an increase in physical activity.

Altered atmospheric circulation, reductions in Arctic sea ice, ocean warming, and changes in evaporation and transpiration are driving changes in the global hydrologic cycle. Precipitation isotopic (d 18 O and d 2 H) measurements can help provide a mechanistic understanding of hydrologic change at global and regional scales. To study the changing water cycle in the northeastern US, we examined the longest (1968-2010) record of precipitation isotope values, collected at the Hubbard Brook Experimental Forest in New Hampshire, US (43 o 56′N, 71 o 45′W). We found a significant reduction in d 18 O and d 2 H values over the 43-year record, coupled with a significant increase in d-excess values. This gradual reduction in d 18 O and d 2 H values unexpectedly occurred during a period of regional warming. We provide evidence that these changes are governed by the interactions among the Atlantic Multidecadal Oscillation, loss of Arctic sea ice, the fluctuating jet stream, and regular incursions of polar air into the northeastern US.

BACKGROUND: Around 17% of people eligible for UK cardiac rehabilitation programmes following an acute coronary syndrome report moderate or severe depressive symptoms. While maximising psychological health is a core goal of cardiac rehabilitation, psychological care can be fragmented and patchy. This study tests the feasibility and acceptability of embedding enhanced psychological care, composed of two management strategies of proven effectiveness in other settings (nurse-led mental health care coordination and behavioural activation), within the cardiac rehabilitation care pathway. METHODS/DESIGN: This study tests the uncertainties associated with a large-scale evaluation by conducting an external pilot trial with a nested qualitative study. We aim to recruit and randomise eight comprehensive cardiac rehabilitation teams (clusters) to intervention (embedding enhanced psychological care into routine cardiac rehabilitation programmes) or control (routine cardiac rehabilitation programmes alone) arms. Up to 64 patients (eight per team) identified with depressive symptoms upon initial assessment by the cardiac rehabilitation team will be recruited, and study measures will be administered at baseline (before starting rehabilitation) and at 5 months and 8 months post baseline. Outcomes include depressive symptoms, cardiac mortality and morbidity, anxiety, health-related quality of life and service resource use. Trial data on cardiac team and patient recruitment, and the retention and flow of patients through treatment will be used to assess intervention feasibility and acceptability. Qualitative interviews will be undertaken to explore trial participants' and cardiac rehabilitation nurses' views and experiences of the trial methods and intervention, and to identify reasons why patients declined to take part in the trial. Outcome data will inform a sample size calculation for a definitive trial. DISCUSSION: the pilot trial and qualitative study will inform the design of a fully powered cluster randomised controlled trial to evaluate the effectiveness and cost-effectiveness of the provision of enhanced psychological care within cardiac rehabilitation programmes. TRIAL REGISTRATION: ISRCTN34701576 (Registered 29 May 2014).

BACKGROUND: in recent years, hospitals have made use of new technologies, such as real-time feedback, to collect patient experience information. This approach is currently rarely used in primary care settings, but may provide practices with a useful tool that enables them to take prompt, focused action to improve their services. AIM: to identify the factors inhibiting and enabling the implementation of real-time feedback in general practices. DESIGN AND SETTING: Qualitative study embedded within an exploratory trial (July 2014 to February 2015) of a real-time feedback intervention targeting patient experience in general practices in south-west England and Cambridgeshire. METHOD: Semi-structured interviews (n = 22) and focus groups (n = 4, total of 28 attendees) with practice staff were audiorecorded, transcribed, and analysed thematically, using a framework based on constructs from normalisation process theory. RESULTS: Staff engagement with real-time feedback varied considerably, and staff made sense of real-time feedback by comparing it with more familiar feedback modalities. Effective within-team communication was associated with positive attitudes towards real-time feedback. Timing of requests for feedback was important in relation to patient engagement. Real-time feedback may offer potential as a means of informing practice development, perhaps as a component of a wider programme of capturing and responding to patients' comments. CONCLUSION: Successful implementation of real-time feedback requires effective communication across the practice team to engender thorough engagement. Feedback processes should be carefully introduced to fit with existing patient and practice routines. Future studies should consider making real-time feedback content relevant to specific practice needs, and support participation by all patient groups.

Objectives to inform the rational deployment of assessor resource in the evaluation of applications to the UK Advisory Committee on Clinical Excellence Awards (ACCEA). Setting ACCEA are responsible for a scheme to financially reward senior doctors in England and Wales who are assessed to be working over and above the standard expected of their role. Participants Anonymised applications of consultants and senior academic GPs for awards were considered by members of 14 regional subcommittees and 2 national assessing committees during the 2014-2015 round of applications. Design it involved secondary analysis of complete anonymised national data set. Primary and secondary outcome measures We analysed scores for each of 1916 applications for a clinical excellence award across 4 levels of award. Scores were provided by members of 16 subcommittees. We assessed the reliability of assessments and described the variance in the assessment of scores. Results Members of regional subcommittees assessed 1529 new applications and 387 renewal applications. Average scores increased with the level of application being made. On average, applications were assessed by 9.5 assessors. The highest contributions to the variance in individual assessors' assessments of applications were attributable to assessors or to residual variance. The applicant accounted for around a quarter of the variance in scores for new bronze applications, with this proportion decreasing for higher award levels. Reliability in excess of 0.7 can be attained where 4 assessors score bronze applications, with twice as many assessors being required for higher levels of application. Conclusions Assessment processes pertaining in the competitive allocation of public funds need to be credible and efficient. The present arrangements for assessing and scoring applications are defensible, depending on the level of reliability judged to be required in the assessment process. Some relatively minor reconfiguration in approaches to scoring might usefully be considered in future rounds of assessment.

BACKGROUND: a 2014 national audit used the English General Practice Patient Survey (GPPS) to compare service users' experience of out-of-hours general practitioner (GP) services, yet there is no published evidence on the validity of these GPPS items. OBJECTIVES: Establish the construct and concurrent validity of GPPS items evaluating service users' experience of GP out-of-hours care. METHODS: Cross-sectional postal survey of service users (n=1396) of six English out-of-hours providers. Participants reported on four GPPS items evaluating out-of-hours care (three items modified following cognitive interviews with service users), and 14 evaluative items from the Out-of-hours Patient Questionnaire (OPQ). Construct validity was assessed through correlations between any reliable (Cochran's α>0.7) scales, as suggested by a principal component analysis of the modified GPPS items, with the 'entry access' (four items) and 'consultation satisfaction' (10 items) OPQ subscales. Concurrent validity was determined by investigating whether each modified GPPS item was associated with thematically related items from the OPQ using linear regressions. RESULTS: the modified GPPS item-set formed a single scale (α=0.77), which summarised the two-component structure of the OPQ moderately well; explaining 39.7% of variation in the 'entry access' scores (r=0.63) and 44.0% of variation in the 'consultation satisfaction' scores (r=0.66), demonstrating acceptable construct validity. Concurrent validity was verified as each modified GPPS item was highly associated with a distinct set of related items from the OPQ. CONCLUSIONS: Minor modifications are required for the English GPPS items evaluating out-of-hours care to improve comprehension by service users. A modified question set was demonstrated to comprise a valid measure of service users' overall satisfaction with out-of-hours care received. This demonstrates the potential for the use of as few as four items in benchmarking providers and assisting services in identifying, implementing and assessing quality improvement initiatives.

BACKGROUND: Study attrition has the potential to compromise a trial's internal and external validity. The aim of the present study was to identify factors associated with participant attrition in a pilot trial of the effectiveness of a novel behavioural support intervention focused on increasing physical activity to reduce smoking, to inform the methods to reduce attrition in a definitive trial. METHODS: Disadvantaged smokers who wanted to reduce but not quit were randomised (N = 99), of whom 61 (62 %) completed follow-up assessments at 16 weeks. Univariable logistic regression was conducted to determine the effects of intervention arm, method of recruitment, and participant characteristics (sociodemographic factors, and lifestyle, behavioural and attitudinal characteristics) on attrition, followed by multivariable logistic regression on those factors found to be related to attrition. RESULTS: Participants with low confidence to quit, and who were undertaking less than 150 mins of moderate and vigorous physical activity per week at baseline were less likely to complete the 16-week follow-up assessment. Exploratory analysis revealed that those who were lost to follow-up early in the trial (i.e. by 4 weeks), compared with those completing the study, were younger, had smoked for fewer years and had lower confidence to quit in the next 6 months. Participants who recorded a higher expired air carbon monoxide reading at baseline were more likely to drop out late in the study, as were those recruited via follow-up telephone calls. Multivariable analyses showed that only completing less than 150 mins of physical activity retained any confidence in predicting attrition in the presence of other variables. CONCLUSIONS: the findings indicate that those who take more effort to be recruited, are younger, are heavier smokers, have less confidence to quit, and are less physically active are more likely to withdraw or be lost to follow-up.

BACKGROUND: Differences in blood pressure between arms are associated with increased cardiovascular mortality in cohorts with established vascular disease or substantially elevated cardiovascular risk. AIM: to explore the association of inter-arm difference (IAD) with mortality in a community-dwelling cohort that is free of cardiovascular disease. DESIGN AND SETTING: Cohort analysis of a randomised controlled trial in central Scotland, from April 1998 to October 2008. METHOD: Volunteers from Lanarkshire, Glasgow, and Edinburgh, free of pre-existing vascular disease and with an ankle-brachial index ≤0.95, had systolic blood pressure measured in both arms at recruitment. Inter-arm blood pressure differences were calculated and examined for cross-sectional associations and differences in prospective survival. Outcome measures were cardiovascular events and all-cause mortality during mean follow-up of 8.2 years. RESULTS: Based on a single pair of measurements, 60% of 3350 participants had a systolic IAD ≥5 mmHg and 38% ≥10 mmHg. An IAD ≥5 mmHg was associated with increased cardiovascular mortality (adjusted hazard ratio [HR] 1.91, 95% confidence interval [CI] = 1.19 to 3.07) and all-cause mortality (adjusted HR 1.44, 95% CI = 1.15 to 1.79). Within the subgroup of 764 participants who had hypertension, IADs of ≥5 mmHg or ≥10 mmHg were associated with both cardiovascular mortality (adjusted HR 2.63, 95% CI = 0.97 to 7.02, and adjusted HR 2.96, 95% CI = 1.27 to 6.88, respectively) and all-cause mortality (adjusted HR 1.67, 95% CI = 1.05 to 2.66, and adjusted HR 1.63, 95% CI = 1.06 to 2.50, respectively). IADs ≥15 mmHg were not associated with survival differences in this population. CONCLUSION: Systolic IADs in blood pressure are associated with increased risk of cardiovascular events, including mortality, in a large cohort of people free of pre-existing vascular disease.

BACKGROUND: GPs collect multisource feedback (MSF) about their professional practice and discuss it at appraisal. Appraisers use such information to identify concerns about a doctor's performance, and to guide the doctor's professional development plan (PDP). AIM: to investigate whether GP appraisers detect variation in doctors' MSF results, and the degree of consensus in appraisers' interpretations of this information. DESIGN AND SETTING: Online study of GP appraisers in north-east England. METHOD: GP appraisers were invited to review eight anonymised doctors' MSF reports, which represented different patterns of scores on the UK General Medical Council's Patient and Colleague Questionnaires. Participants provided a structured assessment of each doctor's report, and recommended actions for their PDP. Appraiser ratings of each report were summarised descriptively. An 'agreement score' was calculated for each appraiser to determine whether their assessments were more lenient than those of other participants. RESULTS: at least one report was assessed by 101/146 appraisers (69%). The pattern of appraisers' ratings suggested that they could detect variation in GPs' MSF results, and recommend reasonable actions for the doctors' PDP. Increasing appraiser age was associated with more favourable interpretations of MSF results. CONCLUSION: Although preliminary, the finding of broad consensus among GP appraisers in their assessment of MSF reports should be reassuring for GPs, appraisers, and employing organisations. However, if older appraisers are more lenient than younger appraisers in their interpretation of MSF and in the actions they suggest to their appraisees as a result, organisations need to consider what steps could be taken to address such differences.

BACKGROUND: Longer consultations in primary care have been linked with better quality of care and improved health-related outcomes. However, there is little evidence of any potential association between consultation length and patient experience. AIM: to examine the relationship between consultation length and patient-reported communication, trust and confidence in the doctor, and overall satisfaction. DESIGN AND SETTING: Analysis of 440 videorecorded consultations and associated patient experience questionnaires from 13 primary care practices in England. METHOD: Patients attending a face-to-face consultation with participating GPs consented to having their consultations videoed and completed a questionnaire. Consultation length was calculated from the videorecording. Linear regression (adjusting for patient and doctor demographics) was used to investigate associations between patient experience (overall communication, trust and confidence, and overall satisfaction) and consultation length. RESULTS: There was no evidence that consultation length was associated with any of the three measures of patient experience (P >0.3 for all). Adjusted changes on a 0-100 scale per additional minute of consultation were: communication score 0.02 (95% confidence interval [CI] = -0.20 to 0.25), trust and confidence in the doctor 0.07 (95% CI = -0.27 to 0.41), and satisfaction -0.14 (95% CI = -0.46 to 0.18). CONCLUSION: the authors found no association between patient experience measures of communication and consultation length, and patients may sometimes report good experiences from very short consultations. However, longer consultations may be required to achieve clinical effectiveness and patient safety: aspects also important for achieving high quality of care. Future research should continue to study the benefits of longer consultations, particularly for patients with complex multiple conditions.

BACKGROUND: People with depression are usually managed in primary care and antidepressants are often the first-line treatment, but only one third of patients respond fully to a single antidepressant. This paper describes the protocol for a randomised controlled trial (MIR) to investigate the extent to which the addition of the antidepressant mirtazapine is effective in reducing the symptoms of depression compared with placebo in patients who are still depressed after they have been treated with a selective serotonin reuptake inhibitor (SSRI) or serotonin and noradrenaline reuptake inhibitor (SNRI) for at least 6 weeks in primary care. METHODS/DESIGN: MIR is a two-parallel group, multi-centre, pragmatic, placebo controlled, randomised trial with allocation at the level of the individual. Eligible participants are those who: are aged 18 years or older; are currently taking an SSRI/SNRI antidepressant (for at least 6 weeks at an adequate dose); score ≥ 14 on the Beck Depression Inventory (BDI-II); have adhered to their medication; and meet ICD-10 criteria for depression (assessed using the Clinical Interview Schedule-Revised version). Participants who give written, informed consent, will be randomised to receive either oral mirtazapine or matched placebo, starting at 15 mg daily for 2 weeks and increasing to 30 mg daily thereafter, for up to 12 months (to be taken in addition to their usual antidepressant). Participants, their GPs, and the research team will all be blind to the allocation. The primary outcome will be depression symptoms at 12 weeks post randomisation, measured as a continuous variable using the BDI-II. Secondary outcomes (measured at 12, 24 and 52 weeks) include: response (reduction in depressive symptoms (BDI-II score) of at least 50% compared to baseline); remission of depression symptoms (BDI-II

Over three million people aged over 65 fall each year in the UK. Postural hypotension (PH) is a risk factor for falls. It is associated with excess mortality, and may affect cognition. PH is not routinely checked for in UK clinical practice. We studied the InCHIANTI dataset to derive and validate a simple prediction tool designed to facilitate identification of subjects to be checked for PH.InCHIANTI is a population-based study of ageing. It recruited subjects from population registries in Chianti, Italy in 1998 and they were followed up triennially. Blood pressure (BP) at recruitment was measured after resting supine, and one and three minutes after standing, using a mercury sphygmomanometer. Systolic PH was defined as a > = 20 mmHg fall in supine BP on standing. Subjects were randomised to derivation or validation cohorts; allocation was undertaken blinded to PH status and medical history. Candidate predictor variables identified from literature searches were tested for univariable cross sectional associations with PH using χ2 tests. Those with significant associations were entered into multivariable linear regression models, and used to derive simple and weighted prediction scores (DROP scores). DROP scores were tested in the validation cohort for prediction of PH, future falls, cognitive decline and mortality rates.PH was present in 56/726 (7.7%) of the derivation cohort and 45/727 (6.2%) of the validation cohort (p = 0.25). PH was associated with age > = 65, falls in the preceding year, diabetes, previous stroke, hypertension and Parkinson's disease. A simple score summing numbers of these variables performed equally well as weighted scores (AUROC 0.67 (0.59 to 0.74); p 

This study explored (1) the incidence of posttraumatic stress disorder (PTSD) resulting from past trauma among older patients with COPD and (2) whether PTSD and COPD severity would relate to psychiatric co-morbidity and health-related quality of life. Eighty-five older patients completed the Hospital Anxiety and Depression Scale, the Chronic Respiratory Questionnaire, the Posttraumatic Stress Diagnostic Scale and the Medical Outcomes Short Form 12. The results showed that 55, 39 and 6 % had no, partial and full-PTSD respectively. Partial least squares showed that PTSD was significantly correlated with COPD severity which in turn was significantly correlated with health-related quality of life and psychiatric co-morbidity. Mediational analysis showed that the emotional symptoms of COPD mediated between PTSD and the mental health functioning of health-related quality of life and between PTSD and depression. To conclude, PTSD from past trauma was related to the severity of COPD for older patients. In particular, it impacted on the elevated emotional arousal of COPD severity. In turn, COPD severity impacted on older patients’ general psychological well-being and depression.

BACKGROUND: Various prevalence figures have been reported for inter-arm differences in blood pressure (IAD); variation may be explained by differing population vascular risk and by measurement method. AIM: to review the literature to derive robust estimates of IAD prevalence relevant to community populations. DESIGN AND SETTING: Systematic review and meta-analysis. METHOD: MEDLINE, Embase, and CINAHL were searched for cross-sectional studies likely to represent general or primary care populations, reporting prevalence of IAD and employing a simultaneous method of measurement. Using study-level data, pooled estimates of mean prevalence of systolic IADs were calculated and compared using a random effects model. RESULTS: Eighty IAD studies were identified. Sixteen met inclusion criteria: pooled estimates of prevalence for systolic IAD ≥10 mmHg were 11.2% (95% confidence interval [CI] = 9.1 to 13.6) in hypertension, 7.4% (95% CI = 5.8 to 9.2) in diabetes, and 3.6% (95% CI = 2.3 to 5.0) for a general adult population (P

Objective: Primary care services form the foundation of modern healthcare systems, yet the breadth and complexity of services and diversity of patient populations may present challenges for creating comprehensive primary care information systems. Our objective is to develop regional-level information on the performance of primary care in Canada. Methods: a scoping review was conducted to identify existing initiatives in primary care performance measurement and reporting across 11 countries. The results of this review were used by our international team of primary care researchers and clinicians to propose an approach for regional-level primary care reporting. Results: We found a gap between conceptual primary care performance measurement frameworks in the peer-reviewed literature and real-world primary care performance measurement and reporting activities. We did not find a conceptual framework or analytic approach that could readily form the foundation of a regional-level primary care information system. Therefore, we propose an approach to reporting comprehensive and actionable performance information according to widely accepted core domains of primary care as well as different patient population groups. Conclusions: an approach that bridges the gap between conceptual frameworks and realworld performance measurement and reporting initiatives could address some of the potential pitfalls of existing ways of presenting performance information (i.e. by single diseases or by age). This approach could produce meaningful and actionable information on the quality of primary care services.

Purpose: the validity and reliability of various items on the GP Patient Survey (GPPS) survey have been reported, however stability of patient responses over time has not been tested. The purpose of this study was to determine the test–retest reliability of the core items from the GPPS. Methods: Patients who had recently consulted participating GPs in five general practices across the South West England were sent a postal questionnaire comprising of 54 items concerning their experience of their consultation and the care they received from the GP practice. Patients returning the questionnaire within 3 weeks of mail-out were sent a second identical (retest) questionnaire. Stability of responses was assessed by raw agreement rates and Cohen’s kappa (for categorical response items) and intraclass correlation coefficients and means (for ordinal response items). Results: 348 of 597 Patients returned a retest questionnaire (58.3 % response rate). In comparison to the test phase, patients responding to the retest phase were older and more likely to have white British ethnicity. Raw agreement rates for the 33 categorical items ranged from 66 to 100 % (mean 88 %) while the kappa coefficients ranged from 0.00 to 1.00 (mean 0.53). Intraclass correlation coefficients for the 21 ordinal items averaged 0.67 (range 0.44–0.77). Conclusions: Formal testing of items from the national GP patient survey examining patient experience in primary care highlighted their acceptable temporal stability several weeks following a GP consultation.

BACKGROUND: English National Quality Requirements mandate out-of-hours primary care services to routinely audit patient experience, but do not state how it should be done. OBJECTIVES: We explored how providers collect patient feedback data and use it to inform service provision. We also explored staff views on the utility of out-of-hours questions from the English General Practice Patient Survey (GPPS). METHODS: a qualitative study was conducted with 31 staff (comprising service managers, general practitioners and administrators) from 11 out-of-hours primary care providers in England, UK. Staff responsible for patient experience audits within their service were sampled and data collected via face-to-face semistructured interviews. RESULTS: Although most providers regularly audited their patients' experiences by using patient surveys, many participants expressed a strong preference for additional qualitative feedback. Staff provided examples of small changes to service delivery resulting from patient feedback, but service-wide changes were not instigated. Perceptions that patients lacked sufficient understanding of the urgent care system in which out-of-hours primary care services operate were common and a barrier to using feedback to enable change. Participants recognised the value of using patient experience feedback to benchmark services, but perceived weaknesses in the out-of-hours items from the GPPS led them to question the validity of using these data for benchmarking in its current form. CONCLUSIONS: the lack of clarity around how out-of-hours providers should audit patient experience hinders the utility of the National Quality Requirements. Although surveys were common, patient feedback data had only a limited role in service change. Data derived from the GPPS may be used to benchmark service providers, but refinement of the out-of-hours items is needed.

OBJECTIVES: in many countries, minority ethnic groups report poorer care in patient surveys. This could be because they get worse care or because they respond differently to such surveys. We conducted an experiment to determine whether South Asian people in England rate simulated GP consultations the same or differently from White British people. If these groups rate consultations similarly when viewing identical simulated consultations, it would be more likely that the lower scores reported by minority ethnic groups in real surveys reflect real differences in quality of care. DESIGN: Experimental vignette study. Trained fieldworkers completed computer-assisted personal interviews during which participants rated 3 video recordings of simulated GP-patient consultations, using 5 communication items from the English GP Patient Survey. Consultations were shown in a random order, selected from a pool of 16. SETTING: Geographically confined areas of ∼130 households (output areas) in England, selected using proportional systematic sampling. PARTICIPANTS: 564 White British and 564 Pakistani adults recruited using an in-home face-to-face approach. MAIN OUTCOME MEASURE: Mean differences in communication score (on a scale of 0-100) between White British and Pakistani participants, estimated from linear regression. RESULTS: Pakistani participants, on average, scored consultations 9.8 points higher than White British participants (95% CI 8.0 to 11.7, p

OBJECTIVE: to investigate the reasons behind intentions to quit direct patient care among experienced general practitioners (GPs) aged 50-60 years. DESIGN AND SETTING: Qualitative study based on semistructured interviews with GPs in the South West region of England. Transcribed interviews were analysed thematically. PARTICIPANTS: 23 GPs aged 50-60 years: 3 who had retired from direct patient care before age 60, and 20 who intended to quit direct patient care within the next 5 years. RESULTS: the analysis identified four key themes: early retirement is a viable option for many GPs; GPs have employment options other than undertaking direct patient care; GPs report feeling they are doing an (almost) undoable job; and GPs may have other aspirations that pull them away from practice. Findings from this study confirmed those from earlier research, with high workload, ageing and health, family and domestic life, and organisational change all influencing GPs' decisions about when to retire/quit direct patient care. However, in addition, GPs expressed feelings of insecurity and uncertainty regarding the future of general practice, low morale, and issues regarding accountability (appraisal and revalidation) and governance. Suggestions about how to help retain GPs within the active clinical workforce were offered, covering individual, practice and organisational levels. CONCLUSIONS: This research highlights aspects of the current professional climate for GPs that are having an impact on retirement decisions. Any future changes to policy or practice to help retain experienced GPs will benefit from this informed understanding of GPs' views. Key factors to take into account include: making the GP workload more manageable; managing change sympathetically; paying attention to GPs' own health; improving confidence in the future of general practice; and improving GP morale.

BACKGROUND: the ubiquitous use of communication technologies has led to an expectation that a similar approach should extend to health care. Despite considerable rhetoric about the need for general practices to offer alternatives to face-to-face consultations, such as telephone, email, and internet video consultations, the extent to which such technologies are actually used at present is unclear. AIM: the aim of the survey was to identify the frequency and range of ways in which general practices are providing (or planning) alternatives to face-to-face consultations. DESIGN AND SETTING: a postal survey of practices around Bristol, Oxford, Lothian, the Highlands, and the Western Isles of Scotland. METHOD: a postal questionnaire survey was sent to each of the GPs and practice managers of 421 practices between January and May 2015. RESULTS: a response was received from 319/421 practices (76%). Although the majority of the practices reported that they were conducting telephone consultations frequently (n = 211/318, 66%), fewer were implementing email consultations (n = 18/318, 6%), and most (n = 169/318, 53%) had no plans to introduce this. None were currently using internet video, and 86% (n = 273/318) had no plans to introduce internet video consultations. These findings were repeated in the reported use of alternatives to face-to-face consultations at an individual GP level. Optional free text responses were completed by 28% of responders, and offered an explanation for the (often perceived) barriers and incentives for implementation. CONCLUSION: Despite policy pressure to introduce consultations by email and internet video, there is a general reluctance among GPs to implement alternatives to face-to-face consultations. This identifies a substantial gap between rhetoric and reality in terms of the likelihood of certain alternatives (email, video) changing practice in the near future.

BACKGROUND: Doctor-patient communication is a key driver of overall satisfaction with primary care. Patients from minority ethnic backgrounds consistently report more negative experiences of doctor-patient communication. However, it is currently unknown whether these ethnic differences are concentrated in one gender or in particular age groups. AIM: to determine how reported GP-patient communication varies between patients from different ethnic groups, stratified by age and gender. DESIGN AND SETTING: Analysis of data from the English GP Patient Survey from 2012-2013 and 2013-2014, including 1,599,801 responders. METHOD: a composite score was created for doctor-patient communication from five survey items concerned with interpersonal aspects of care. Mixed-effect linear regression models were used to estimate age- and gender-specific differences between white British patients and patients of the same age and gender from each other ethnic group. RESULTS: There was strong evidence (P

OBJECTIVE: to investigate the experience of users of out of hours general practitioner services in England, UK. DESIGN: Population based cross sectional postal questionnaire survey. SETTING: General Practice Patient Survey 2012-13. MAIN OUTCOME MEASURES: Potential associations between sociodemographic factors (including ethnicity and ability to take time away from work during working hours to attend a healthcare consultation) and provider organisation type (not for profit, NHS, or commercial) and service users' experience of out of hours care (timeliness, confidence and trust in the out of hours clinician, and overall experience of the service), rated on a scale of 0-100. Which sociodemographic/provider characteristics were associated with service users' experience, the extent to which any observed differences could be because of clustering of service users of a particular sociodemographic group within poorer scoring providers, and the extent to which observed differences in experience varied across types of provider. RESULTS: the overall response rate was 35%; 971,232/2,750,000 patients returned surveys. Data from 902,170 individual service users were mapped through their registered practice to one of 86 providers of out of hours GP care with known organisation type. Commercial providers of out of hours GP care were associated with poorer reports of overall experience of care, with a mean difference of -3.13 (95% confidence interval -4.96 to -1.30) compared with not for profit providers. Asian service users reported lower scores for all three experience outcomes than white service users (mean difference for overall experience of care -3.62, -4.36 to -2.89), as did service users who were unable to take time away from work compared with service users who did not work (mean difference for overall experience of care -4.73, -5.29 to -4.17). CONCLUSIONS: Commercial providers of out of hours GP care were associated with poorer experience of care. Targeted interventions aimed at improving experience for patients from ethnic minorities and patients who are unable to take time away from work might be warranted.

BACKGROUND: There is limited evidence about the impact of specific patterns of multi-morbidity on health-related quality of life (HRQoL) from large samples of adult subjects. METHODS: We used data from the English General Practice Patient Survey 2011-2012. We defined multi-morbidity as the presence of two or more of 12 self-reported conditions or another (unspecified) long-term health problem. We investigated differences in HRQoL (EQ-5D scores) associated with combinations of these conditions after adjusting for age, gender, ethnicity, socio-economic deprivation and the presence of a recent illness or injury. Analyses were based on 831,537 responses from patients aged 18 years or older in 8,254 primary care practices in England. RESULTS: of respondents, 23 % reported two or more chronic conditions (ranging from 7 % of those under 45 years of age to 51 % of those 65 years or older). Multi-morbidity was more common among women, White individuals and respondents from socio-economically deprived areas. Neurological problems, mental health problems, arthritis and long-term back problem were associated with the greatest HRQoL deficits. The presence of three or more conditions was commonly associated with greater reduction in quality of life than that implied by the sum of the differences associated with the individual conditions. The decline in quality of life associated with an additional condition in people with two and three physical conditions was less for older people than for younger people. Multi-morbidity was associated with a substantially worse HRQoL in diabetes than in other long-term conditions. With the exception of neurological conditions, the presence of a comorbid mental health problem had a more adverse effect on HRQoL than any single comorbid physical condition. CONCLUSION: Patients with multi-morbid diabetes, arthritis, neurological, or long-term mental health problems have significantly lower quality of life than other people. People with long-term health conditions require integrated mental and physical healthcare services.

The ESTEEM trial was a randomised-controlled trial of telephone triage consultations in general practice. We conducted exploratory analyses on data from 9154 patients from 42 UK general practices who returned a questionnaire containing self-reported ratings of satisfaction with care following a request for a same-day consultation. Mode of care was identified through case notes review. There were seven main types: a GP face-to-face consultation, GP or nurse telephone triage consultation with no subsequent same day care, or a GP or nurse telephone triage consultation with a subsequent face-to-face consultation with a GP or a nurse. We investigated the contribution of mode of care to patient satisfaction and distance between the patient’s home and the practice as a potential moderating factor. There was no overall association between patient satisfaction and distance from practice. However, patients managed by a nurse telephone consultation showed lowest levels of satisfaction, and satisfaction for this group of patients increased the further they lived from the practice. There was no association between any of the other modes of management and distance from practice.

INTRODUCTION: it is believed that some patients are more likely to use out-of-hours primary care services because of difficulties in accessing in-hours care, but substantial evidence about any such association is missing. METHODS: We analysed data from 567,049 respondents to the 2011/2012 English General Practice Patient Survey who reported at least one in-hours primary care consultation in the preceding 6�
months. of those respondents, 7% also reported using out-of-hours primary care. We used logistic regression to explore associations between use of out-of-hours primary care and five measures of in-hours access (ease of getting through on the telephone, ability to see a preferred general practitioner, ability to get an urgent or routine appointment and convenience of opening hours). We illustrated the potential for reduction in use of out-of-hours primary care in a model where access to in-hours care was made optimal. RESULTS: Worse in-hours access was associated with greater use of out-of-hours primary care for each access factor. In multivariable analysis adjusting for access and patient characteristic variables, worse access was independently associated with increased out-of-hours use for all measures except ease of telephone access. Assuming these associations were causal, we estimated that an 11% relative reduction in use of out-of-hours primary care services in England could be achievable if access to in-hours care were optimal. CONCLUSIONS: This secondary quantitative analysis provides evidence for an association between difficulty in accessing in-hours care and use of out-of-hours primary care services. The findings can motivate the development of interventions to improve in-hour access.

Objective We compared the distribution by wealth of self-reported illness burden (estimated from validated scales, biomarker and reported symptoms) for angina, cataract, depression, diabetes and osteoarthritis, with the distribution of self-reported medical diagnosis and treatment. We aimed to determine if the greater illness burden borne by poorer participants was matched by appropriately higher levels of diagnosis and treatment.Design the English Longitudinal Study of Ageing, a panel study of 12�
765 participants aged 50�
years and older in four waves from 2004 to 2011, selected using a stratified random sample of households in England. Distribution of illness burden, diagnosis and treatment by wealth was estimated using regression analysis.Outcome measures the main outcome measures were ORs for the illness burden, diagnosis and treatment, respectively, adjusted for age, sex and wealth. We estimated the illness burden for angina with the Rose Angina scale, diabetes with fasting glycosylated haemoglobin, depression with the Centre for Epidemiologic Studies Depression Scale, osteoarthritis with self-reported pain and disability and cataract with self-reported poor vision. Medical diagnoses were self-reported for all conditions. Treatment was defined as β-blocker prescription for angina, surgery for osteoarthritis and cataract, and receipt of predefined effective interventions for diabetes and depression.Results Compared with the wealthiest, the least wealthy participant had substantially higher odds for illness burden from any of the five conditions at all four time points, with ORs ranging from 4.2 (95% CI 2.6 to 6.8) for diabetes to 15.1 (11.4 to 20.0) for osteoarthritis. The ORs for diagnosis and treatment were smaller in all five conditions, and ranged from 0.9 (0.5 to 1.4) for diabetes treatment to 4.5 (3.3 to 6.0) for angina diagnosis.Conclusions the substantially higher illness burden in less wealthy participants was not matched by appropriately higher levels of diagnosis and treatment.

OBJECTIVE: to evaluate two 5-item patient experience scales from the English General Practice (GP) Patient Survey for evidence of differential item functioning (DIF) given prior evidence of substantially worse reported health care experiences for South Asian compared with white British respondents. SETTING: a national survey of English patients' primary care experiences. METHOD: We used classic test and item response theory analysis to examine the possibility of DIF by patient ethnicity (South Asian, white British) after controlling for age, sex, health status, and quality of life in the English GP Patient Survey conducted in 2011/2012. RESULTS: Data were available for 873,051 respondents (818,219 white British/54,832 South Asian from 7795 English practices) who answered items relating to experiences of GP or nurses' care. Internal consistency reliability was high and similar for South Asian and white British patients. White British patients reported better average experiences than South Asians, but there was no evidence of DIF or different item response curves for white British and South Asian respondents, even in sensitivity analyses using matched samples. CONCLUSIONS: all communication items in the English GP Patient Survey showed similar South Asian versus white British differences, with no evidence of DIF. In contrast, differences due to scale use or expectations are typically variable rather than constant across scales. While other possibilities remain, these findings increase the likelihood that the observed negative responses of South Asian patients to this national survey reflect true differences in their experiences of care.

BACKGROUND: the ESTEEM trial was a cluster randomised controlled trial that compared two telephone triage management systems (general practitioner (GP) or a nurse supported by computer decision support software) with usual care, in response to a request for same-day consultation in general practice. AIM: to investigate associations between trial patients' demographic, health, and lifestyle characteristics, and their reported experiences of care. SETTING: Recruitment of 20�
990 patients occurred between May 2011 and December 2012 in 42 GP practices in England (13 GP triage, 15 nurse triage, 14 usual care). METHOD: Patients reported their experiences via a postal questionnaire issued 4�
weeks after their initial request for a same-day consultation. Overall satisfaction, ease of accessing medical help/advice, and convenience of care were analysed using linear hierarchical modelling. RESULTS: Questionnaires were returned by 12�
132 patients (58%). Older patients reported increased overall satisfaction compared with patients aged 25-59�
years, but patients aged 16-24�
years reported lower satisfaction. Compared with white patients, patients from ethnic minorities reported lower satisfaction in all three arms, although to a lesser degree in the GP triage arm. Patients from ethnic minorities reported higher satisfaction in the GP triage than in usual care, whereas white patients reported higher satisfaction with usual care. Patients unable to take time away from work or who could only do so with difficulty reported lower satisfaction across all three trial arms. CONCLUSIONS: Patient characteristics, such as age, ethnicity and ability to attend their practice during work hours, were associated with their experiences of care following a same-day consultation request in general practice. Telephone triage did not increase satisfaction among patients who were unable to attend their practice during working hours. TRIAL REGISTRATION NUMBER: ISCRTN20687662.

PURPOSE: the purpose of this study was to examine the association between the prevalence of both diabetes-concordant and diabetes-discordant conditions and the quality of diabetes care at the family practice level in England. We hypothesized that the prevalence of concordant (or discordant) conditions would be associated with better (or worse) quality of diabetes care. METHODS: We conducted a cross-sectional study using practice-level data (7,884 practices). We estimated the practice-level prevalence of diabetes and 15 other chronic conditions, which were classified as diabetes concordant (ie, with the same pathophysiologic risk profile and therefore more likely to be part of the same management plan) or diabetes discordant (ie, not directly related in either their pathogenesis or management). We measured quality of diabetes care with diabetes-specific indicators (8 processes and 3 intermediate outcomes of care). We used linear regression models to quantify the effect of the prevalence of the conditions on aggregate achievement rate for quality of diabetes care. RESULTS: Consistent with the proposed model, the prevalence rates of 4 of 7 concordant conditions (obesity, chronic kidney disease, atrial fibrillation, heart failure) were positively associated with quality of diabetes care. Similarly, negative associations were observed as predicted for 2 of the 8 discordant conditions (epilepsy, mental health). Observations for other concordant and discordant conditions did not match predictions in the hypothesized model. CONCLUSIONS: the quality of diabetes care provided in English family practices is associated with the prevalence of other major chronic conditions at the practice level. The nature and direction of the observed associations cannot be fully explained by the concordant-discordant model.

BACKGROUND: Telephone triage represents one strategy to manage demand for face-to-face GP appointments in primary care. However, limited evidence exists of the challenges GP practices face in implementing telephone triage. We conducted a qualitative process evaluation alongside a UK-based cluster randomised trial (ESTEEM) which compared the impact of GP-led and nurse-led telephone triage with usual care on primary care workload, cost, patient experience, and safety for patients requesting a same-day GP consultation. The aim of the process study was to provide insights into the observed effects of the ESTEEM trial from the perspectives of staff and patients, and to specify the circumstances under which triage is likely to be successfully implemented. Here we report perspectives of staff. METHODS: the intervention comprised implementation of either GP-led or nurse-led telephone triage for a period of 2-3 months. A qualitative evaluation was conducted using staff interviews recruited from eight general practices (4 GP triage, 4 Nurse triage) in the UK, implementing triage as part of the ESTEEM trial. Qualitative interviews were undertaken with 44 staff members in GP triage and nurse triage practices (16 GPs, 8 nurses, 7 practice managers, 13 administrative staff). RESULTS: Staff reported diverse experiences and perceptions regarding the implementation of telephone triage, its effects on workload, and on the benefits of triage. Such diversity were explained by the different ways triage was organised, the staffing models used to support triage, how the introduction of triage was communicated across practice staff, and by how staff roles were reconfigured as a result of implementing triage. CONCLUSION: the findings from the process evaluation offer insight into the range of ways GP practices participating in ESTEEM implemented telephone triage, and the circumstances under which telephone triage can be successfully implemented beyond the context of a clinical trial. Staff experiences and perceptions of telephone triage are shaped by the way practices communicate with staff, prepare for and sustain the changes required to implement triage effectively, as well as by existing practice culture, and staff and patient behaviour arising in response to the changes made.

© 2016 Wiles et al. Open Access article distributed under the terms of CC BY. Background: Cognitive behavioural therapy (CBT) is an effective treatment for people whose depression has not responded to antidepressants. However, the long-term outcome is unknown. In a long-term follow-up of the CoBalT trial, we examined the clinical and cost-effectiveness of cognitive behavioural therapy as an adjunct to usual care that included medication over 3-5 years in primary care patients with treatment-resistant depression. Methods: CoBalT was a randomised controlled trial done across 73 general practices in three UK centres. CoBalT recruited patients aged 18-75 years who had adhered to antidepressants for at least 6 weeks and had substantial depressive symptoms (Beck Depression Inventory [BDI-II] score ≥14 and met ICD-10 depression criteria). Participants were randomly assigned using a computer generated code, to receive either usual care or CBT in addition to usual care. Patients eligible for the long-term follow-up were those who had not withdrawn by the 12 month follow-up and had given their consent to being re-contacted. Those willing to participate were asked to return the postal questionnaire to the research team. One postal reminder was sent and non-responders were contacted by telephone to complete a brief questionnaire. Data were also collected from general practitioner notes. Follow-up took place at a variable interval after randomisation (3-5 years). The primary outcome was self-report of depressive symptoms assessed by BDI-II score (range 0-63), analysed by intention to treat. Cost-utility analysis compared health and social care costs with quality-adjusted life-years (QALYs). This study is registered with isrctn.com, number ISRCTN38231611. Findings: Between Nov 4, 2008, and Sept 30, 2010, 469 eligible participants were randomised into the CoBalT study. of these, 248 individuals completed a long-term follow-up questionnaire and provided data for the primary outcome (136 in the intervention group vs 112 in the usual care group). At follow-up (median 45·5 months [IQR 42·5-51·1]), the intervention group had a mean BDI-II score of 19·2 (SD 13·8) compared with a mean BDI-II score of 23·4 (SD 13·2) for the usual care group (repeated measures analysis over the 46 months: difference in means -4·7 [95% CI -6·4 to -3·0, p

BACKGROUND: Stratified medicine aims to improve clinical and cost-effectiveness by identifying moderators of treatment that indicate differential response to treatment. Cognitive behavioural therapy (CBT) is often offered as a 'next-step' for patients who have not responded to antidepressants, but no research has examined moderators of response to CBT in this population. We aimed, therefore, to identify moderators of response to CBT in treatment resistant depression. METHODS: We used linear regression to test for interactions between treatment effect and 14 putative moderator variables using data from the CoBalT randomised controlled trial. This trial examined the effectiveness of CBT given in addition to usual care (n=234) compared with usual care alone (n=235) for primary care patients with treatment resistant depression. RESULTS: Age was the only variable with evidence for effect modification (p Value for interaction term=0.012), with older patients benefiting the most from CBT. We found no evidence of effect modification by any other demographic, life, illness, personality trait, or cognitive variable (p≥0.2). CONCLUSIONS: Given the largely null findings, a stratified approach that might limit offering CBT is premature; CBT should be offered to all individuals where antidepressant medication has failed.

Suicide is common among offenders, who are at increased risk of homelessness, unemployment and mental illness and are prone to impulsivity. Release from prison is a particularly vulnerable time. This qualitative study investigated the views of 35 offenders in South-West England prior to and after release from prison, enquiring into their previous suicide attempts and how they saw their future. Semi-structured interviews were analysed thematically, comparing individuals who had made one, more than one, and no suicide attempts. Multiple attempters were often in despair and enmeshed in substance misuse, with little control over their lives. Most of those with one-off or no previous attempts portrayed themselves as having more mastery. One-off attempters described using particularly violent means. The role of different types of agency in pathways to and from suicide is discussed. Iterational agency, the selective reactivation of past patterns of behaviour, appeared to dominate in individuals who were choosing between further suicide attempts and substance use. Projective agency, having a more future orientation, appeared more prominent in some single attempters and in those individuals with plans to escape crime and social exclusion.

Aims
Diabetes complications are potentially avoidable, yet incomplete care is common. Little is known about patient characteristics that predict incomplete care.
Methods
English Longitudinal Study of Ageing participants aged 50 years or older with diabetes reported on four diabetes quality indicators (QIs) in 2008-9 and 2010-11. Annual checks for glycated haemoglobin (HbA1c), proteinuria and foot examination were assessed as a care bundle (n=907). A further QI
assessed whether participants with cardiac risk factors were offered ACE inhibitors/receptor blockers
(n=759). Individual's baseline (2008-9) socio-demographic, lifestyle and health characteristics,
diabetes self-management knowledge and health literacy, and previous QI achievement were assessed
with logistic regressions on outcomes in 2010-11.
Results
A third of participants (2008-9=32.8%; 2010-11=32.2%) did not receive all annual checks in the care
bundle. Nearly half of those eligible were not offered ACE inhibitors/receptor blockers (2008-
9=44.6%; 2010-11=44.5%). Odds of not receiving a complete care bundle were increased for
participants lacking diabetes self-management knowledge (OR=2.05), having poorer cognitive
performance (OR=1.78) or having previously received incomplete care (OR=3.32). Participants who
were single (OR=2.16), had with low health literacy (OR=1.50) and who had received incomplete care
previously (OR=6.94) were less likely to subsequently be offered ACE inhibitors/receptor blockers,
whereas trend test showed that being older (OR=0.76) and increased BMI categorisation (OR=0.70)
improved odds of receiving this aspect of care.
Conclusions
Quality improvement initiatives for diabetes might usefully target patients with characteristics shown
here to predict non-receipt of indicated care, such as poor knowledge of annual diabetes care
processes or previous receipt of incomplete care.

BACKGROUND: Telephone triage is proposed as a method of managing increasing demand for primary care. Previous studies have involved small samples in limited settings, and focused on nurse roles. Evidence is limited regarding the impact on primary care workload, costs, and patient safety and experience when triage is used to manage patients requesting same-day consultations in general practice. OBJECTIVES: in comparison with usual care (UC), to assess the impact of GP-led telephone triage (GPT) and nurse-led computer-supported telephone triage (NT) on primary care workload and cost, patient experience of care, and patient safety and health status for patients requesting same-day consultations in general practice. DESIGN: Pragmatic cluster randomised controlled trial, incorporating economic evaluation and qualitative process evaluation. SETTING: General practices (n = 42) in four regions of England, UK (Devon, Bristol/Somerset, Warwickshire/Coventry, Norfolk/Suffolk). PARTICIPANTS: Patients requesting same-day consultations. INTERVENTIONS: Practices were randomised to GPT, NT or UC. Data collection was not blinded; however, analysis was conducted by a statistician blinded to practice allocation. MAIN OUTCOME MEASURES: Primary - primary care contacts [general practice, out-of-hours primary care, accident and emergency (A&E) and walk-in centre attendances] in the 28 days following the index consultation request. Secondary - resource use and costs, patient safety (deaths and emergency hospital admissions within 7 days of index request, and A&E attendance within 28 days), health status and experience of care. RESULTS: of 20,990 eligible randomised patients (UC n = 7283; GPT n = 6695; NT n = 7012), primary outcome data were analysed for 16,211 patients (UC n = 5572; GPT n = 5171; NT n = 5468). Compared with UC, GPT and NT increased primary outcome contacts (over 28-day follow-up) by 33% [rate ratio (RR) 1.33, 95% confidence interval (CI) 1.30 to 1.36] and 48% (RR 1.48, 95% CI 1.44 to 1.52), respectively. Compared with GPT, NT was associated with a marginal increase in primary outcome contacts by 4% (RR 1.04, 95% CI 1.01 to 1.08). Triage was associated with a redistribution of primary care contacts. Although GPT, compared with UC, increased the rate of overall GP contacts (face to face and telephone) over the 28 days by 38% (RR 1.38, 95% CI 1.28 to 1.50), GP face-to-face contacts were reduced by 39% (RR 0.61, 95% CI 0.54 to 0.69). NT reduced the rate of overall GP contacts by 16% (RR 0.84, 95% CI 0.78 to 0.91) and GP face-to-face contacts by 20% (RR 0.80, 95% CI 0.71 to 0.90), whereas nurse contacts increased. The increased rate of primary care contacts in triage arms is largely attributable to increased telephone contacts. Estimated overall patient-clinician contact time on the index day increased in triage (GPT = 10.3 minutes; NT = 14.8 minutes; UC = 9.6 minutes), although patterns of clinician use varied between arms. Taking account of both the pattern and duration of primary outcome contacts, overall costs over the 28-day follow-up were similar in all three arms (approximately £75 per patient). Triage appeared safe, and no differences in patient health status were observed. NT was somewhat less acceptable to patients than GPT or UC. The process evaluation identified the complexity associated with introducing triage but found no consistency across practices about what works and what does not work when implementing it. CONCLUSIONS: Introducing GPT or NT was associated with a redistribution of primary care workload for patients requesting same-day consultations, and at similar cost to UC. Although triage seemed to be safe, investigation of the circumstances of a larger number of deaths or admissions after triage might be warranted, and monitoring of these events is necessary as triage is implemented.

BackgroundShortfalls in the receipt of recommended health care have been previously reported in England, leading to preventable poor health.ObjectivesTo assess changes over 6 years in the receipt of effective health-care interventions for people aged 50 years or over in England with cardiovascular disease, depression, diabetes or osteoarthritis; to identify how quality varied with participant characteristics; and to compare the distribution of illness burden in the population with the distributions of diagnosis and treatment.Setting and participantsInformation on health-care quality indicators and participant characteristics was collected using face-to-face structured interviews and nurse visits in participants’ homes by the English Longitudinal Study of Ageing in 2004–5, 2006–7, 2008–9 and 2010–11. A total of 16,773 participants aged 50 years or older were interviewed at least once and 5114 were interviewed in all four waves; 5404 reported diagnosis of one or more of four conditions in 2010–11.Main outcome measuresPercentage of indicated health care received by eligible participants for 19 quality indicators: seven for cardiovascular disease, three for depression, five for diabetes and four for osteoarthritis, and condition-level quality indicator achievement, including achievement of a bundle of three diabetes indicators.AnalysisChanges in quality indicator achievement over time and variations in quality with participant characteristics were tested with Pearson’s chi-squared test and logistic regression models. The size of inequality between the hypothetically wealthiest and poorest participants, for illness burden, diagnosis and treatment, was estimated using slope indices of wealth inequality.ResultsAchievement of indicators for cardiovascular disease was 82.7% [95% confidence interval (CI) 79.9% to 85.5%] in 2004–5 and 84.2% (95% CI 82.1% to 86.2%) in 2010–11, for depression 63.3% (95% CI 57.6% to 69.0%) and 59.8% (95% CI 52.4% to 64.3%), for diabetes 76.0% (95% CI 74.1% to 77.8%) and 76.5% (95% CI 74.8% to 78.1%), and for osteoarthritis 31.2% (95% CI 28.5% to 33.8%) and 35.6% (95% CI 34.2% to 37.1%). Achievement of the diabetes care bundle was 67.8% (95% CI 64.5% to 70.9%) in 2010–11. Variations in quality by participant characteristics were generally small. Diabetes indicator achievement was worse in participants with cognitive impairment [odds ratio (OR) 0.5, 95% CI 0.4 to 0.7] and better in those living alone (OR 1.7, 95% CI 1.3 to 2.0). Hypertension care was better for those aged over 74 years (vs. 50–64 years) (OR 3.2, 95% CI 2.0 to 5.3). Osteoarthritis care was better for those with severe (vs. mild) pain (OR 1.8, 95% CI 1.4 to 2.2), limiting illness (OR 1.8, 95% CI 1.5 to 2.1), and obesity (OR 1.6, 95% CI 1.2 to 2.0). Previous non-achievement of the diabetes care bundle was the biggest predictor of non-achievement 2 years later (OR 3.3, 95% CI 2.2 to 4.7). Poorer participants were always more likely than wealthier participants to have illness burden (statistically significant OR 3.9 to 16.0), but not always more likely to be diagnosed or receive treatment (0.2 to 5.3).ConclusionsShortfalls in quality of care for these four conditions have persisted over 6 years, with only half of the level of indicated health care achieved for osteoarthritis, compared with the other three conditions. Quality for osteoarthritis improved slightly over time but remains poor. The relatively high prevalence of specific illness burden in poorer participants was not matched by an equally high prevalence of diagnosis or treatment, suggesting that barriers to equity may exist at the stage at diagnosis. Further research is needed into the association between quality and health system characteristics at the level of clinicians, general practices or hospitals, and regions. Linkage to routinely collected data could provide information on health service characteristics at the individual patient level.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Telephone triage represents one strategy to manage demand for face-to-face GP appointments in primary care. Although computer decision-support software (CDSS) is increasingly used by nurses to triage patients, little is understood about how interaction is organized in this setting. Specifically any interactional dilemmas this computer-mediated setting invokes; and how these may be consequential for communication with patients. Using conversation analytic methods we undertook a multi-modal analysis of 22 audio-recorded telephone triage nurse-caller interactions from one GP practice in England, including 10 video-recordings of nurses' use of CDSS during triage. We draw on Goffman's theoretical notion of participation frameworks to make sense of these interactions, presenting 'telling cases' of interactional dilemmas nurses faced in meeting patient's needs and accurately documenting the patient's condition within the CDSS. Our findings highlight troubles in the 'interactional workability' of telephone triage exposing difficulties faced in aligning the proximal and wider distal context that structures CDSS-mediated interactions. Patients present with diverse symptoms, understanding of triage consultations, and communication skills which nurses need to negotiate turn-by-turn with CDSS requirements. Nurses therefore need to have sophisticated communication, technological and clinical skills to ensure patients' presenting problems are accurately captured within the CDSS to determine safe triage outcomes. Dilemmas around how nurses manage and record information, and the issues of professional accountability that may ensue, raise questions about the impact of CDSS and its use in supporting nurses to deliver safe and effective patient care.

BACKGROUND: Despite widespread adoption of patient feedback surveys in international health-care systems, including the English NHS, evidence of a demonstrable impact of surveys on service improvement is sparse. OBJECTIVE: to explore the views of primary care practice staff regarding the utility of patient experience surveys. DESIGN: Qualitative focus groups. SETTING AND PARTICIPANTS: Staff from 14 English general practices. RESULTS: Whilst participants engaged with feedback from patient experience surveys, they routinely questioned its validity and reliability. Participants identified surveys as having a number of useful functions: for patients, as a potentially therapeutic way of getting their voice heard; for practice staff, as a way of identifying areas of improvement; and for GPs, as a source of evidence for professional development and appraisal. Areas of potential change stimulated by survey feedback included redesigning front-line services, managing patient expectations and managing the performance of GPs. Despite this, practice staff struggled to identify and action changes based on survey feedback alone. DISCUSSION: Whilst surveys may be used to endorse existing high-quality service delivery, their use in informing changes in service delivery is more challenging for practice staff. Drawing on the Utility Index framework, we identified concerns relating to reliability and validity, cost and feasibility acceptability and educational impact, which combine to limit the utility of patient survey feedback. CONCLUSIONS: Feedback from patient experience surveys has great potential. However, without a specific and renewed focus on how to translate feedback into action, this potential will remain incompletely realized.

BACKGROUND: Open-ended questions eliciting free-text comments have been widely adopted in surveys of patient experience. Analysis of free text comments can provide deeper or new insight, identify areas for action, and initiate further investigation. Also, they may be a promising way to progress from documentation of patient experience to achieving quality improvement. The usual methods of analyzing free-text comments are known to be time and resource intensive. To efficiently deal with a large amount of free-text, new methods of rapidly summarizing and characterizing the text are being explored. OBJECTIVE: the aim of this study was to investigate the feasibility of using freely available Web-based text processing tools (text clouds, distinctive word extraction, key words in context) for extracting useful information from large amounts of free-text commentary about patient experience, as an alternative to more resource intensive analytic methods. METHODS: We collected free-text responses to a broad, open-ended question on patients' experience of primary care in a cross-sectional postal survey of patients recently consulting doctors in 25 English general practices. We encoded the responses to text files which were then uploaded to three Web-based textual processing tools. The tools we used were two text cloud creators: TagCrowd for unigrams, and Many Eyes for bigrams; and Voyant Tools, a Web-based reading tool that can extract distinctive words and perform Keyword in Context (KWIC) analysis. The association of patients' experience scores with the occurrence of certain words was tested with logistic regression analysis. KWIC analysis was also performed to gain insight into the use of a significant word. RESULTS: in total, 3426 free-text responses were received from 7721 patients (comment rate: 44.4%). The five most frequent words in the patients' comments were "doctor", "appointment", "surgery", "practice", and "time". The three most frequent two-word combinations were "reception staff", "excellent service", and "two weeks". The regression analysis showed that the occurrence of the word "excellent" in the comments was significantly associated with a better patient experience (OR=1.96, 95%CI=1.63-2.34), while "rude" was significantly associated with a worse experience (OR=0.53, 95%CI=0.46-0.60). The KWIC results revealed that 49 of the 78 (63%) occurrences of the word "rude" in the comments were related to receptionists and 17(22%) were related to doctors. CONCLUSIONS: Web-based text processing tools can extract useful information from free-text comments and the output may serve as a springboard for further investigation. Text clouds, distinctive words extraction and KWIC analysis show promise in quick evaluation of unstructured patient feedback. The results are easily understandable, but may require further probing such as KWIC analysis to establish the context. Future research should explore whether more sophisticated methods of textual analysis (eg, sentiment analysis, natural language processing) could add additional levels of understanding.

OBJECTIVES: to describe and explain the primary care experiences of people with multiple long-term conditions in England. DESIGN AND METHODS: Using questionnaire data from 906,578 responders to the English 2012 General Practice Patient Survey, we describe the primary care experiences of patients with long-term conditions, including 583,143 patients who reported one or more long-term conditions. We employed mixed effect logistic regressions to analyse data on six items covering three care domains (access, continuity and communication) and a single item on overall primary care experience. We controlled for sociodemographic characteristics, and for general practice using a random effect, and further, controlled for, and explored the importance of, health-related quality of life measured using the EuroQoL (EQ-5D) scale. RESULTS: Most patients with long-term conditions report a positive experience of care at their general practice (after adjusting for sociodemographic characteristics and general practice, range 74.0-93.1% reporting positive experience of care across seven questions) with only modest variation by type of condition. For all three domains of patient experience, an increasing number of comorbid conditions is associated with a reducing percentage of patients reporting a positive experience of care. For example, compared with respondents with no long-term condition, the OR for reporting a positive experience is 0.83 (95% CI 0.80 to 0.87) for respondents with four or more long-term conditions. However, this relationship is no longer observed after adjusting for health-related quality of life (OR (95% CI) single condition=1.23 (1.21 to 1.26); four or more conditions=1.31 (1.25 to 1.37)), with pain making the greatest difference among five quality of life variables included in the analysis. CONCLUSIONS: Patients with multiple long-term conditions more frequently report worse experiences in primary care. However, patient-centred measures of health-related quality of life, especially pain, are more important than the number of conditions in explaining why patients with multiple long-term conditions report worse experiences of care.

BACKGROUND: There have been few rigorous studies on the effects of behavioural support for helping smokers to reduce who do not immediately wish to quit. While reduction may not have the health benefits of quitting, it may lead smokers to want to quit. Physical activity (PA) helps to reduce cravings and withdrawal symptoms, and also reduces weight gain after quitting, but smokers may be less inclined to exercise. There is scope to develop and determine the effectiveness of interventions to support smoking reduction and increase physical activity, for those not ready to quit. OBJECTIVE: to conduct a pilot randomised controlled trial (RCT) [Exercise Assisted Reduction then Stop (EARS) smoking study] to (1) design and evaluate the feasibility and acceptability of a PA and smoking-reduction counselling intervention [for disadvantaged smokers who do not wish to quit but do want to reduce their smoking (to increase the likelihood of quitting)], and (2) to inform the design of a large RCT to determine the clinical effectiveness and cost-effectiveness of the intervention. DESIGN: a single-centre, pragmatic, pilot trial with follow-up up to 16 weeks. A mixed methods approach assessed the acceptability and feasibility of the intervention and trial methods. Smokers were individually randomised to intervention or control arms. SETTING: General practices, NHS buildings, community venues, and the Stop Smoking Service (SSS) within Plymouth, UK. PARTICIPANTS: Aged > 18 years, smoking ≥ 10 cigarettes per day (for ≥ 2 years) who wished to cut down. We excluded individuals who were contraindicated for moderate PA, posed a safety risk to the research team, wished to quit immediately or use Nicotine Replacement Therapy, not registered with a general practitioner, or did not converse in English. INTERVENTION: We designed a client-centred, counselling-based intervention designed to support smoking reduction and increases in PA. Support sessions were delivered by trained counsellors either face to face or by telephone. Both intervention and control arms were given information at baseline on specialist SSS support available should they have wished to quit. MAIN OUTCOME MEASURES: the primary outcome was 4-week post-quit expired air carbon monoxide (CO)-confirmed abstinence from smoking. Secondary outcomes included validated behavioural, cognitive and emotional/affective and health-related quality of life measures and treatment costs. RESULTS: the study randomised 99 participants, 49 to the intervention arm and 50 to the control arm, with a 62% follow-up rate at 16 weeks. In the intervention and control arms, 14% versus 4%, respectively [relative risk = 3.57; 95% confidence interval (CI) 0.78 to 16.35], had expired CO-confirmed abstinence at least 4 and up to 8 weeks after quit day; 22% versus 6% (relative risk = 3.74; 95% CI 1.11 to 12.60) made a quit attempt; 10% versus 4% (relative risk = 92.55; 95% CI 0.52 to 12.53) achieved point-prevalent abstinence at 16 weeks; and 39% versus 20% (relative risk = 1.94; 95% CI 1.01 to 3.74) achieved at least a 50% reduction in the number of cigarettes smoked daily. The percentage reporting using PA for controlling smoking in the intervention versus control arms was 55% versus 22%, respectively at 8 weeks and 37% versus 16%, respectively, at 16 weeks. The counsellors generally delivered the intervention as planned and participants responded with a variety of smoking reduction strategies, sometimes supported by changes in PA. The intervention costs were approximately £192 per participant. Exploratory cost-effectiveness modelling indicates that the intervention may be cost-effective. CONCLUSIONS: the study provided valuable information on the resources needed to improve study recruitment and retention. Offering support for smoking reduction and PA appears to have value in promoting reduction and cessation in disadvantaged smokers not currently motivated to quit. A large RCT is needed to assess the clinical effectiveness and cost-effectiveness of the intervention in this population. TRIAL REGISTRATION: ISRCTN 13837944.

Background: Acupuncture and related techniques are promoted as a treatment for smoking cessation in the belief that they may reduce nicotine withdrawal symptoms. Objectives: the objectives of this review are to determine the effectiveness of acupuncture and the related interventions of acupressure, laser therapy and electrostimulation in smoking cessation, in comparison with no intervention, sham treatment, or other interventions. Search methods: We searched the Cochrane Tobacco Addiction Group Specialized Register (which includes trials of smoking cessation interventions identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and PsycINFO) and AMED in October 2013. We also searched four Chinese databases in September 2013: Sino-Med, China National Knowledge Infrastructure, Wanfang Data and VIP. Selection criteria: Randomized trials comparing a form of acupuncture, acupressure, laser therapy or electrostimulation with either no intervention, sham treatment or another intervention for smoking cessation. Data collection and analysis: We extracted data in duplicate on the type of smokers recruited, the nature of the intervention and control procedures, the outcome measures, method of randomization, and completeness of follow-up. We assessed abstinence from smoking at the earliest time-point (before six weeks) and at the last measurement point between six months and one year. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. Those lost to follow-up were counted as continuing smokers. Where appropriate, we performed meta-analysis pooling risk ratios using a fixed-effect model. Main results: We included 38 studies. Based on three studies, acupuncture was not shown to be more effective than a waiting list control for long-term abstinence, with wide confidence intervals and evidence of heterogeneity (n = 393, risk ratio [RR] 1.79, 95% confidence interval [CI] 0.98 to 3.28, I2 = 57%). Compared with sham acupuncture, the RR for the short-term effect of acupuncture was 1.22 (95% CI 1.08 to 1.38), and for the long-term effect was 1.10 (95% CI 0.86 to 1.40). The studies were not judged to be free from bias, and there was evidence of funnel plot asymmetry with larger studies showing smaller effects. The heterogeneity between studies was not explained by the technique used. Acupuncture was less effective than nicotine replacement therapy (NRT). There was no evidence that acupuncture is superior to psychological interventions in the short- or long-term. There is limited evidence that acupressure is superior to sham acupressure for short-term outcomes (3 trials, n = 325, RR 2.54, 95% CI 1.27 to 5.08), but no trials reported long-term effects, the pooled estimate for studies testing an intervention that included continuous auricular stimulation suggested a short-term benefit compared to sham stimulation (14 trials, n = 1155, RR 1.69, 95% CI 1.32 to 2.16); subgroup analysis showed an effect for continuous acupressure (7 studies, n = 496, RR 2.73, 95% CI 1.78 to 4.18) but not acupuncture with indwelling needles (6 studies, n = 659, RR 1.24, 95% CI 0.91 to 1.69). At longer follow-up the CIs did not exclude no effect (5 trials, n = 570, RR 1.47, 95% CI 0.79 to 2.74). The evidence from two trials using laser stimulation was inconsistent and could not be combined. The combined evidence on electrostimulation suggests it is not superior to sham electrostimulation (short-term abstinence: 6 trials, n = 634, RR 1.13, 95% CI 0.87 to 1.46; long-term abstinence: 2 trials, n = 405, RR 0.87, 95% CI 0.61 to 1.23). Authors' conclusions: Although pooled estimates suggest possible short-term effects there is no consistent, bias-free evidence that acupuncture, acupressure, or laser therapy have a sustained benefit on smoking cessation for six months or more. However, lack of evidence and methodological problems mean that no firm conclusions can be drawn. Electrostimulation is not effective for smoking cessation. Well-designed research into acupuncture, acupressure and laser stimulation is justified since these are popular interventions and safe when correctly applied, though these interventions alone are likely to be less effective than evidence-based interventions.

Background: Data from trials suggest that antibiotics reduce the risk of complications of sore throat by at least 50%, but few trials for complications have been done in modern settings, and datasets of delayed antibiotic prescription are underpowered. Observational evidence is important in view of poor compliance with antibiotic treatment outside trials, but no prospective observational cohort studies have been done to date. Methods: We generated a large prospective cohort from the DESCARTE study, and the PRISM component of DESCARTE, of 12829 adults presenting with sore throat (≤2 weeks duration) in primary care. Our follow-up of the cohort was based on a detailed and structured review of routine medical records, and analysis of the comparison of three antibiotic prescription strategies (no antibiotic prescription, immediate antibiotic prescription, and delayed antibiotic prescription) to control for the propensity to prescribe antibiotics. Information about antibiotic prescription was recorded in 12677 individuals (4805 prescribed no antibiotics, 6088 prescribed antibiotics immediately, and 1784 prescribed delayed antibiotics). We documented by review of patients' notes (n=11950) the development of suppurative complications (eg, quinsy, impetigo and cellulitis, otitis media, and sinusitis) or reconsultation with new or non-resolving symptoms). We used multivariate analysis to control for variables significantly related to the propensity to prescribe antibiotics and for clustering by general practitioner. Findings: 164 (1·4%) of the 11950 patients with information available developed complications; otitis media and sinusitis were the most common complications (101 patients [62%]). Compared with no antibiotic prescription, immediate antibiotic prescription was associated with fewer complications (adjusted risk ratio [RR] 0·62, 95% CI 0·43-0·91, estimated number needed to treat [NNT 193) as was delayed prescription of antibiotics (0·58, 0·34-0·98; NNT 174). 1787 of the 11950 patients (15%) reconsulted with new or non-resolving symptoms; the risk of reconsultation was also reduced by immediate (0·83, 0·73-0·94; NNT 40) or delayed antibiotics (0·61, 0·50-0·74; NNT 18). Interpretation: Suppurative complications are not common in primary care and most are not serious. The risks of suppurative complications or reconsultation in adults are reduced by antibiotics, but not as much as the trial evidence suggests. In most cases, no antibiotic is needed, but a delayed prescription strategy is likely to provide similar benefits to an immediate antibiotic prescription.

Objectives: to investigate initial reliability of the Global Consultation Rating Scale (GCRS: an instrument to assess the effectiveness of communication across an entire doctor-patient consultation, based on the Calgary-Cambridge guide to the medical interview), in simulated patient consultations. Design: Multiple ratings of simulated general practitioner (GP)-patient consultations by trained GP evaluators. Setting: UK primary care. Participants: 21 GPs and six trained GP evaluators. Outcome measures: GCRS score. Methods: 6 GP raters used GCRS to rate randomly assigned video recordings of GP consultations with simulated patients. Each of the 42 consultations was rated separately by four raters. We considered whether a fixed difference between scores had the same meaning at all levels of performance. We then examined the reliability of GCRS using mixed linear regression models. We augmented our regression model to also examine whether there were systematic biases between the scores given by different raters and to look for possible order effects. Results: Assessing the communication quality of individual consultations, GCRS achieved a reliability of 0.73 (95% CI 0.44 to 0.79) for two raters, 0.80 (0.54 to 0.85) for three and 0.85 (0.61 to 0.88) for four. We found an average difference of 1.65 (on a 0-10 scale) in the scores given by the least and most generous raters: adjusting for this evaluator bias increased reliability to 0.78 (0.53 to 0.83) for two raters; 0.85 (0.63 to 0.88) for three and 0.88 (0.69 to 0.91) for four. There were considerable order effects, with later consultations (after 15-20 ratings) receiving, on average, scores more than one point higher on a 0-10 scale. Conclusions: GCRS shows good reliability with three raters assessing each consultation. We are currently developing the scale further by assessing a large sample of real-world consultations.

BACKGROUND: Only one-third of patients with depression respond fully to treatment with antidepressant medication. However, there is little robust evidence to guide the management of those whose symptoms are 'treatment resistant'. OBJECTIVE: the CoBalT trial examined the clinical effectiveness and cost-effectiveness of cognitive behavioural therapy (CBT) as an adjunct to usual care (including pharmacotherapy) for primary care patients with treatment-resistant depression (TRD) compared with usual care alone. DESIGN: Pragmatic, multicentre individually randomised controlled trial with follow-up at 3, 6, 9 and 12 months. A subset took part in a qualitative study investigating views and experiences of CBT, reasons for completing/not completing therapy, and usual care for TRD. SETTING: General practices in Bristol, Exeter and Glasgow, and surrounding areas. PARTICIPANTS: Patients aged 18-75 years who had TRD [on antidepressants for ≥ 6 weeks, had adhered to medication, Beck Depression Inventory, 2nd version (BDI-II) score of ≥ 14 and fulfilled the International Classification of Diseases and Related Health Problems, Tenth edition criteria for depression]. Individuals were excluded who (1) had bipolar disorder/psychosis or major alcohol/substance abuse problems; (2) were unable to complete the questionnaires; or (3) were pregnant, as were those currently receiving CBT/other psychotherapy/secondary care for depression, or who had received CBT in the past 3 years. INTERVENTIONS: Participants were randomised, using a computer-generated code, to usual care or CBT (12-18 sessions) in addition to usual care. MAIN OUTCOME MEASURES: the primary outcome was 'response', defined as ≥ 50% reduction in depressive symptoms (BDI-II score) at 6 months compared with baseline. Secondary outcomes included BDI-II score as a continuous variable, remission of symptoms (BDI-II score of < 10), quality of life, anxiety and antidepressant use at 6 and 12 months. Data on health and social care use, personal costs, and time off work were collected at 6 and 12 months. Costs from these three perspectives were reported using a cost-consequence analysis. A cost-utility analysis compared health and social care costs with quality adjusted life-years. RESULTS: a total of 469 patients were randomised (intervention: n = 234; usual care: n = 235), with 422 participants (90%) and 396 (84%) followed up at 6 and 12 months. Ninety-five participants (46.1%) in the intervention group met criteria for 'response' at 6 months compared with 46 (21.6%) in the usual-care group {odds ratio [OR] 3.26 [95% confidence interval (CI) 2.10 to 5.06], p < 0.001}. In repeated measures analyses using data from 6 and 12 months, the OR for 'response' was 2.89 (95% CI 2.03 to 4.10, p < 0.001) and for a secondary 'remission' outcome (BDI-II score of < 10) 2.74 (95% CI 1.82 to 4.13, p < 0.001). The mean cost of CBT per participant was £ 910, the incremental health and social care cost £ 850, the incremental QALY gain 0.057 and incremental cost-effectiveness ratio £ 14,911. Forty participants were interviewed. Patients described CBT as challenging but helping them to manage their depression; listed social, emotional and practical reasons for not completing treatment; and described usual care as mainly taking medication. CONCLUSIONS: Among patients who have not responded to antidepressants, augmenting usual care with CBT is effective in reducing depressive symptoms, and these effects, including outcomes reflecting remission, are maintained over 12 months. The intervention was cost-effective based on the National Institute for Health and Care Excellence threshold. Patients may experience CBT as difficult but effective. Further research should evaluate long-term effectiveness, as this would have major implications for the recommended treatment of depression. TRIAL REGISTRATION: Current Controlled Trials ISRCTN38231611.

BACKGROUND: Depression is expensive to treat, but providing ineffective treatment is more expensive. Such is the case for many patients who do not respond to antidepressant medication. AIMS: to assess the cost-effectiveness of cognitive-behavioural therapy (CBT) plus usual care for primary care patients with treatment-resistant depression compared with usual care alone. METHOD: Economic evaluation at 12 months alongside a randomised controlled trial. Cost-effectiveness assessed using a cost-consequences framework comparing cost to the health and social care provider, patients and society, with a range of outcomes. Cost-utility analysis comparing health and social care costs with quality-adjusted life-years (QALYs). RESULTS: the mean cost of CBT per participant was £910. The difference in QALY gain between the groups was 0.057, equivalent to 21 days a year of good health. The incremental cost-effectiveness ratio was £14 911 (representing a 74% probability of the intervention being cost-effective at the National Institute of Health and Care Excellence threshold of £20 000 per QALY). Loss of earnings and productivity costs were substantial but there was no evidence of a difference between intervention and control groups. CONCLUSIONS: the addition of CBT to usual care is cost-effective in patients who have not responded to antidepressants. Primary care physicians should therefore be encouraged to refer such individuals for CBT.

BACKGROUND: the magnitude of the 'white coat effect', the alerting rise in blood pressure, is greater for doctors than nurses. This could bias interpretation of studies on nurse-led care in hypertension, and risks overestimating or overtreating high blood pressure by doctors in clinical practice. AIM: to quantify differences between blood pressure measurements made by doctors and nurses. DESIGN AND SETTING: Systematic review and meta-analysis using searches of MEDLINE, CENTRAL, CINAHL, Embase, journal collections, and conference abstracts. METHOD: Studies in adults reporting mean blood pressures measured by doctors and nurses at the same visit were selected, and mean blood pressures extracted, by two reviewers. Study risk of bias was assessed using modified Cochrane criteria. Outcomes were pooled across studies using random effects meta-analysis. RESULTS: in total, 15 studies (11 hypertensive; four mixed hypertensive and normotensive populations) were included from 1899 unique citations. Compared with doctors' measurements, nurse-measured blood pressures were lower (weighted mean differences: systolic -7.0 [95% confidence interval {CI} = -4.7 to -9.2] mmHg, diastolic -3.8 [95% CI = -2.2 to -5.4] mmHg). For studies at low risk of bias, differences were lower: systolic -4.6 (95% CI = -1.9 to -7.3) mmHg; diastolic -1.7 (95% CI = -0.1 to -3.2) mmHg. White coat hypertension was diagnosed more frequently based on doctors' than on nurses' readings: relative risk 1.6 (95% CI =1.2 to 2.1). CONCLUSIONS: the white coat effect is smaller for blood pressure measurements made by nurses than by doctors. This systematic difference has implications for hypertension diagnosis and management. Caution is required in pooling data from studies using both nurse- and doctor-measured blood pressures.

Sedimentary rocks examined by the Curiosity rover at Yellowknife Bay, Mars, were derived from sources that evolved from an approximately average martian crustal composition to one influenced by alkaline basalts. No evidence of chemical weathering is preserved, indicating arid, possibly cold, paleoclimates and rapid erosion and deposition. The absence of predicted geochemical variations indicates that magnetite and phyllosilicates formed by diagenesis under low-temperature, circumneutral pH, rock-dominated aqueous conditions. Analyses of diagenetic features (including concretions, raised ridges, and fractures) at high spatial resolution indicate that they are composed of iron- and halogen-rich components, magnesium-iron-chlorine - rich components, and hydrated calcium sulfates, respectively. Composition of a cross-cutting dike-like feature is consistent with sedimentary intrusion. The geochemistry of these sedimentary rocks provides further evidence for diverse depositional and diagenetic sedimentary environments during the early history of Mars.

Background: Interventions promoting physical activity by General Practitioners (GPs) lack a strong evidence base. Recruiting participants to trials in primary care is challenging. We investigated the feasibility of (i) delivering three interventions to promote physical activity in inactive participants and (ii) different methods of participant recruitment and randomised allocation.Methods: We recruited general practices from Devon, Bristol and Coventry. We used a 2-by-2 factorial design for participant recruitment and randomisation. Recruitment strategies were either opportunistic (approaching patients attending their GP surgery) or systematic (selecting patients from practice lists and approaching them by letter). Randomisation strategies were either individual or by practice cluster. Feasibility outcomes included time taken to recruit the target number of participants within each practice. Participants were randomly allocated to one of three interventions: (i) written advice (control); (ii) brief GP advice (written advice plus GP advice on physical activity), and (iii) brief GP advice plus a pedometer to self-monitor physical activity during the trial. Participants allocated to written advice or brief advice each received a sealed pedometer to record their physical activity, and were instructed not to unseal the pedometer before the scheduled day of data collection. Participant level outcomes were reported descriptively and included the mean number of pedometer steps over a 7-day period, and European Quality of Life (EuroQoL)-5 dimensions (EQ-5D) scores, recorded at 12 weeks' follow-up.Results: We recruited 24 practices (12 using each recruitment method; 18 randomising by cluster, 6 randomising by individual participant), encompassing 131 participants. Opportunistic recruitment was associated with less time to target recruitment compared with systematic (mean difference (days) -54.9, 95% confidence interval (CI) -103.6; -6.2) but with greater loss to follow up (28.8% versus. 6.9%; mean difference 21.9% (95% CI 9.6%; 34.1%)). There were differences in the socio-demographic characteristics of participants according to recruitment method. There was no clear pattern of change in participant level outcomes from baseline to 12 weeks across the three arms.Conclusions: Delivering and trialling GP-led interventions to promote physical activity is feasible, but trial design influences time to participant recruitment, participant withdrawal, and possibly, the socio-demographic characteristics of participants.Trial registration number: ISRCTN73725618. © 2014 Warren et al.; licensee BioMed Central Ltd.

BACKGROUND: Older patients differ from younger patients in their perceptions of trust in doctors; their sense of shared decision making is particularly associated with their trust in the GP. Enhancing trust and improving shared decision making are thought to have positive health outcomes. Older patients are sometimes reported as being less frequently involved in decisions about their health care, however, and in having more unmet healthcare needs than younger patients. AIM: This study explored older patients' trust in their GPs and their perceptions of shared decision making. DESIGN AND SETTING: Qualitative methods were used. Systematic sampling identified 20 participants, aged ≥65 years, from three GP surgeries in Devon, UK. METHOD: a constant comparative approach was applied to thematic analysis of transcribed interviews. RESULTS: all participants valued feeling involved in decisions but differed regarding how they felt involved. Trust influenced preferences for shared decision making: a trusted GP 'ally', to competently manage participants' increasing health-information requirements throughout the vulnerable ageing process, was important. Trust was affected by factors contributing to the facilitation of involvement. GP characteristics, communication skills, consultation duration, and continuity of care were common themes. CONCLUSION: Although limited geographically and subsequently by ethnic group, the present sample allows for reasonable transferability of the study to other UK populations. A range of factors are highlighted for consideration when planning primary healthcare delivery: to facilitate the optimal involvement of older patients in decisions about their health care, while enhancing their trust in the GP; to help minimise potential health inequalities for this patient group.

Objective: to compare doctors' and nurses' communication with patients in primary care telephone triage consultations. Design: Qualitative comparative study of content and form of questions in 51 telephone triage encounters between practitioners (general practitioners (GPs)=29; nurses=22) and patients requesting a same-day appointment in primary care. Audio-recordings of nurse-led calls were synchronised with video recordings of nurse's use of computer decision support software (CDSS) during triage. Setting: 2 GP practices in Devon and Warwickshire, UK. Participants: 4 GPs and 29 patients; and 4 nurses and 22 patients requesting a same-day face-to-face appointment with a GP. Main outcome measure: Form and content of practitioner-initiated questions and patient responses during clinical assessment. Results: a total of 484 question-response sequences were coded (160 GP; 324 N). Despite average call lengths being similar (GP=4 min, 37 s, (SD=1 min, 26 s); N=4 min, 39 s, (SD=2 min, 22 s)), GPs and nurses differed in the average number (GP=5.51, (SD=4.66); N=14.72, (SD=6.42)), content and form of questions asked. A higher frequency of questioning in nurse-led triage was found to be due to nurses' use of CDSS to guide telephone triage. 89% of nurse questions were oriented to asking patients about their reported symptoms or to wider-information gathering, compared to 54% of GP questions. 43% of GP questions involved eliciting patient concerns or expectations, and obtaining details of medical history, compared to 11% of nurse questions. Nurses using CDSS frequently delivered questions designed as declarative statements requesting confirmation and which typically preferred a 'no problem' response. In contrast, GPs asked a higher proportion of interrogative questions designed to request information. Conclusions: Nurses and GPs emphasise different aspects of the clinical assessment process during telephone triage. These different styles of triage have implications for the type of information available following nurse-led or doctor-led triage, and for how patients experience triage.

BACKGROUND: little is known about changes in the quality of medical care for older adults over time. OBJECTIVE: to assess changes in technical quality of care over 6 years, and associations with participants' characteristics. DESIGN: a national cohort survey covering RAND Corporation-derived quality indicators (QIs) in face-to-face structured interviews in participants' households. PARTICIPANTS: a total of 5,114 people aged 50 or more in four waves of the English Longitudinal Study of Ageing. METHODS: the percentage achievement of 24 QIs in 10 general medical and geriatric clinical conditions was calculated for each time point, and associations with participants' characteristics were estimated using logistic regression. RESULTS: participants were eligible for 21,220 QIs. QI achievement for geriatric conditions (cataract, falls, osteoarthritis and osteoporosis) was 41% [95% confidence interval (CI): 38-44] in 2004-05 and 38% (36-39) in 2010-11. Achievement for general medical conditions (depression, diabetes mellitus, hypertension, ischaemic heart disease, pain and cerebrovascular disease) improved from 75% (73-77) in 2004-05 to 80% (79-82) in 2010-11. Achievement ranged from 89% for cerebrovascular disease to 34% for osteoarthritis. Overall achievement was lower for participants who were men, wealthier, infrequent alcohol drinkers, not obese and living alone. CONCLUSION: substantial system-level shortfalls in quality of care for geriatric conditions persisted over 6 years, with relatively small and inconsistent variations in quality by participants' characteristics. The relative lack of variation by participants' characteristics suggests that quality improvement interventions may be more effective when directed at healthcare delivery systems rather than individuals.

OBJECTIVES: to determine the extent to which practice level scores mask variation in individual performance between doctors within a practice. DESIGN: Analysis of postal survey of patients' experience of face-to-face consultations with individual general practitioners in a stratified quota sample of primary care practices. SETTING: Twenty five English general practices, selected to include a range of practice scores on doctor-patient communication items in the English national GP Patient Survey. PARTICIPANTS: 7721 of 15,172 patients (response rate 50.9%) who consulted with 105 general practitioners in 25 practices between October 2011 and June 2013. MAIN OUTCOME MEASURE: Score on doctor-patient communication items from post-consultation surveys of patients for each participating general practitioner. The amount of variance in each of six outcomes that was attributable to the practices, to the doctors, and to the patients and other residual sources of variation was calculated using hierarchical linear models. RESULTS: After control for differences in patients' age, sex, ethnicity, and health status, the proportion of variance in communication scores that was due to differences between doctors (6.4%) was considerably more than that due to practices (1.8%). The findings also suggest that higher performing practices usually contain only higher performing doctors. However, lower performing practices may contain doctors with a wide range of communication scores. CONCLUSIONS: Aggregating patients' ratings of doctors' communication skills at practice level can mask considerable variation in the performance of individual doctors, particularly in lower performing practices. Practice level surveys may be better used to "screen" for concerns about performance that require an individual level survey. Higher scoring practices are unlikely to include lower scoring doctors. However, lower scoring practices require further investigation at the level of the individual doctor to distinguish higher and lower scoring general practitioners.

H2O, CO2, SO2, O2, H 2, H2S, HCl, chlorinated hydrocarbons, NO, and other trace gases were evolved during pyrolysis of two mudstone samples acquired by the Curiosity rover at Yellowknife Bay within Gale crater, Mars. H 2O/OH-bearing phases included 2:1 phyllosilicate(s), bassanite, akaganeite, and amorphous materials. Thermal decomposition of carbonates and combustion of organic materials are candidate sources for the CO2. Concurrent evolution of O2 and chlorinated hydrocarbons suggests the presence of oxychlorine phase(s). Sulfides are likely sources for sulfur-bearing species. Higher abundances of chlorinated hydrocarbons in the mudstone compared with Rocknest windblown materials previously analyzed by Curiosity suggest that indigenous martian or meteoritic organic carbon sources may be preserved in the mudstone; however, the carbon source for the chlorinated hydrocarbons is not definitively of martian origin.

BACKGROUND: the role of GPs in recruiting or excluding participants critically underpins the feasibility, external validity and generalizability of primary care research. A better understanding of this role is needed. AIM: to investigate why GPs excluded potentially eligible participants from a large scale randomized controlled trial (RCT), to determine the proportion of patients excluded on account of trial eligibility compared with other reasons, and to explore the impact of such exclusions on the management and generalizability of RCTs. DESIGN AND SETTING: Secondary analysis of data from the CoBalT study, a multi-centre general-practice-based RCT investigating cognitive behavioural therapy as an adjunct to pharmacotherapy for treatment-resistant depression. METHOD: GPs were asked to screen patient lists generated from computerized record searches for trial eligibility and to provide narrative reasons for excluding patients. These reasons were coded independently by two researchers, with a third researcher resolving discrepancies. RESULTS: Thirty-one percent (4750/15,379) of patients were excluded at the GP screening stage, including 663 on patient lists that remained unscreened. of the 4087 actively excluded patients, 67% were excluded on account of trial exclusion criteria, 20% for other criteria (half of which were comorbid conditions) and 13% without reason. CONCLUSION: Clear, comprehensive criteria, particularly with regards to comorbidities, are required for GPs to confidently screen patients for potential participation in research. Future studies should promote inclusivity and encourage GPs to adopt a liberal approach when screening patient lists. This would enhance the validity and generalizability of primary care research and encourage greater patient autonomy.

Background Simulated patient, or so-called 'mystery-shopper', studies are a controversial, but potentially useful, approach to take when conducting health services research. Aim to investigate the construct validity of survey questions relating to access to primary care included in the English GP Patient Survey. Design and setting Observational study in 41 general practices in rural, urban, and inner-city settings in the UK. Method Between May 2010 and March 2011, researchers telephoned practices at monthly intervals, simulating patients requesting routine, but prompt, appointments. Seven measures of access and appointment availability, measured from the mystery-shopper contacts, were related to seven measures of practice performance from the GP Patient Survey. Results Practices with lower access scores in the GP Patient Survey had poorer access and appointment availability for five out of seven items measured directly, when compared with practices that had higher scores. Scores on items from the national survey that related to appointment availability were significantly associated with direct measures of appointment availability. Patient-satisfaction levels and the likelihood that patients would recommend their practice were related to the availability of appointments. Patients' reports of ease of telephone access in the national survey were unrelated to three out of four measures of practice call handling, but were related to the time taken to resolve an appointment request, suggesting responders' possible confusion in answering this question. Conclusion Items relating to the accessibility of care in a the English GP patient survey have construct validity. Patients' satisfaction with their practice is not related to practice call handling, but is related to appointment availability. © British Journal of General Practice.

Background the UK government has encouraged NHS services to obtain patient feedback to support the further development of patient-centred care. In 2009, the English GP Patient Survey included a sample of 5.5 million, but little is known about its potential utility in informing developments aimed at improving the quality of patients' experiences of primary care. Aim to investigate primary care providers' response to feedback on patient experience from a national survey. Design and setting Qualitative interview study in 10 general practices from four primary care trusts in England. Method Semi-structured interviews were conducted with GPs, practice nurses, and practice managers (n = 37). Transcripts were analysed thematically. Results Although some participants reported making changes to their practice in response to the survey data, many expressed doubts about the credibility of the results. Key issues included: concerns about practical aspects of the survey, such as the response rate and representativeness of the sample; the view that it gave insufficient detail to facilitate change and failed to address some salient issues; and unease about the influence of political influences underpinning its introduction and use. Conclusion Although, in general, primary care professionals have positive attitudes towards patient feedback, this study suggests a mismatch between the conventional demonstration of the objectivity of a questionnaire survey and the attitudes and experiences of those receiving the data. This is likely to prevent doctors from engaging constructively with the survey. These concerns may well militate against the potential of the survey to act as a simple means of capturing, and effectively using, feedback from patients. © British Journal of General Practice.

Background: Changing family practice (voluntary disenrollment) without changing address may indicate dissatisfaction with care. We investigate the potential to use voluntary disenrollment as a quality indicator for primary care. Methods. Data from the English national GP Patient Survey (2,169,718 respondents), the number of voluntary disenrollments without change of address, data relating to practice characteristics (ethnicity, deprivation, gender of patients, practice size and practice density) and doctor characteristics were obtained for all family practices in England (n = 8450). Poisson regression analyses examined associations between rates of voluntary disenrollment, patient experience, and practice and doctor characteristics. Results: Mean and median rates of annual voluntary disenrollment were 11.2 and 7.3 per 1000 patients respectively. Strongest associations with high rates of disenrollment were low practice scores for doctor-patient communication and confidence and trust in the doctor (rate ratios 4.63 and 4.85). In a fully adjusted model, overall satisfaction encompassed other measures of patient experience (rate ratio 3.46). Patients were more likely to move from small practices (single-handed doctors had 2.75 times the disenrollment rate of practices with 6-9 doctors) and where there were other local practices. After allowing for these, substantial unexplained variation remained in practice rates of voluntary disenrollment. Conclusion: Family practices with low levels of patient satisfaction, especially for doctor patient communication, are more likely to experience high rates of disenrollment. However substantial variation in disenrollment rates remains among practices with similar levels of patient satisfaction, limiting the utility of voluntary disenrollment as a performance indicator for primary care in England. © 2013 Nagraj et al.; licensee BioMed Central Ltd.

Background: the number of elderly people over the age of 65 commencing dialysis in NZ has increased by almost 400% in the past decade. Few data are available about health related outcomes and survival on dialysis in the elderly to help the individual, their family, clinicians and health planners with decision-making. Methods/design. This study will provide the first comprehensive longitudinal survey of health-related quality of life (HRQOL) and other patient centred outcomes for individuals aged ≥65 years on, or eligible for, dialysis therapy and will link these data to survival outcomes. Data collected by yearly structured interviews with participants will be linked to co-morbidity data, health service use, and laboratory information collected from health records, and analysed with respect to HRQOL and survival. The information obtained will inform the delivery of dialysis services in New Zealand and facilitate improved decision-making by individuals, their family and clinicians, about the appropriateness and impact of dialysis therapy on subsequent health and survival. Discussion. Results from this study will make possible more informed decision-making by future elderly patients and their families as they contemplate renal replacement therapy. Results will also allow health professionals to more accurately describe the impact of dialysis therapy on quality of life and outcomes for patients. Trial registration.

Background/objectives: to determine which aspects of primary care matter most to patients, we aim to identify those aspects of patient experience that show the strongest relationship with overall satisfaction and examine the extent to which these relationships vary by socio-demographic and health characteristics. Design/setting: Data from the 2009/10 English General Practice Patient Survey including 2 169 718 respondents registered with 8362 primary care practices. Measures/analyses: Linear mixed-effects regression models (fixed effects adjusting for age, gender, ethnicity, deprivation, self-reported health, self-reported mental health condition and random practice effect) predicting overall satisfaction from six items covering four domains of care: access, helpfulness of receptionists, doctor communication and nurse communication. Additional models using interactions tested whether associations between patient experience and satisfaction varied by socio-demographic group. Results: Doctor communication showed the strongest relationship with overall satisfaction (standardized coefficient 0.48, 95% CI = 0.48, 0.48), followed by the helpfulness of reception staff (standardized coefficient 0.22, 95% CI = 0.22, 0.22). Among six measures of patient experience, obtaining appointments in advance showed the weakest relationship with overall satisfaction (standardized coefficient 0.06, 95% CI = 0.05, 0.06). Interactions showed statistically significant but small variation in the importance of drivers across different patient groups. Conclusions: for all patient groups, communication with the doctor is the most important driver of overall satisfaction with primary care in England, along with the helpfulness of receptionists. In contrast, and despite being a policy priority for government, measures of access, including the ability to obtain appointments, were poorly related to overall satisfaction. © 2013 John Wiley & Sons Ltd.

Objectives: to update previous systematic reviews of interventions targeting asthma self-care in adults with asthma. To use meta-regression to examine the association between the use of specific behavior change techniques and intervention effectiveness.
Methods: Electronic bibliographies were searched systematically to identify randomized controlled trials of interventions targeting asthma self-care. Intervention content was coded using a published taxonomy of behavior change techniques. For trials with a low-to-moderate risk of bias, study outcomes were pooled using random effects meta-analysis. Associations between intervention content and effect size were explored using meta-regression.
Results: Meta-analysis of 38 trials (7883 patients) showed that interventions targeting asthma self-care reduced symptoms (Standardized mean difference (SMD))=-0.38;(-0.52,-0.24)) and unscheduled health care use (Odds ratio (OR))=0.71;(0.56 to 0.90)) and increased adherence to preventive medication (OR=2.55;(2.11 to 3.10)). Meta-regression analyses found that ‘active involvement of participants’ was associated with a reduction in unscheduled health care use (OR=0.50 vs. 0.79). Inclusion of ‘stress management’ techniques was associated with an increase in asthma symptoms (SMD= 0.01vs. -0.44). Existing recommendations about the ‘optimal’ content of asthma self-care interventions were tested, but were not supported by the data.
Conclusions: Interventions targeting asthma self-care are effective. Active involvement of participants is associated with increased intervention effectiveness, but the use of stress management techniques may be counter-productive. Taxonomy based systematic reviews using meta-regression have potential for identifying techniques associated with increased effectiveness in behavioral interventions.

Objectives: Patients' trust in general practitioners (GPs) is fundamental to effective clinical encounters. Associations between patients' trust and their perceptions of communication within the consultation have been identified, but the influence of patients' demographic characteristics on these associations is unknown. We aimed to investigate the relative contribution of the patient's age, gender and ethnicity in any association between patients' ratings of interpersonal aspects of the consultation and their confidence and trust in the doctor. Design: Secondary analysis of English national GP patient survey data (2009). Setting: Primary Care, England, UK. Participants: Data from year 3 of the GP patient survey: 5 660 217 questionnaires sent to patients aged 18 and over, registered with a GP in England for at least 6 months; overall response rate was 42% after adjustment for sampling design. Outcome measures: We used binary logistic regression analysis to investigate patients' reported confidence and trust in the GP, analysing ratings of 7 interpersonal aspects of the consultation, controlling for patients' sociodemographic characteristics. Further modelling examined moderating effects of age, gender and ethnicity on the relative importance of these 7 predictors. Results: Among 1.5 million respondents (adjusted response rate 42%), the sense of 'being taken seriously' had the strongest association with confidence and trust. The relative importance of the 7 interpersonal aspects of care was similar for men and women. Non-white patients accorded higher priority to being given enough time than did white patients. Involvement in decisions regarding their care was more strongly associated with reports of confidence and trust for older patients than for younger patients. Conclusions: Associations between patients' ratings of interpersonal aspects of care and their confidence and trust in their GP are influenced by patients' demographic characteristics. Taking account of these findings could inform patient-centred service design and delivery and potentially enhance patients' confidence and trust in their doctor.

Background: the General Practice Assessment Questionnaire (GPAQ) has been widely used to assess patient experience in general practice in the UK since 2004. In 2013, new regulations were introduced by the General Medical Council (GMC) requiring UK doctors to undertake periodic revalidation, which includes assessment of patient experience for individual doctors. We describe the development of a new version of GPAQ - GPAQ-R which addresses the GMC's requirements for revalidation as well as additional NHS requirements for surveys that GPs may need to carry out in their own practices. Methods. Questionnaires were given out by doctors or practice staff after routine consultations in line with the guidance given by the General Medical Council for surveys to be used for revalidation. Data analysis and practice reports were provided independently. Results: Data were analysed for questionnaires from 7258 patients relating to 164 GPs in 29 general practices. Levels of missing data were generally low (typically 4.5-6%). The number of returned questionnaires required to achieve reliability of 0.7 were around 35 for individual doctor communication items and 29 for a composite score based on doctor communication items. This suggests that the responses to GPAQ-R had similar reliability to the GMC's own questionnaire and we recommend 30 completed GPAQ-R questionnaires are sufficient for revalidation purposes. However, where an initial screen raises concern, the survey might be repeated with 50 completed questionnaires in order to increase reliability. Conclusions: GPAQ-R is a development of a well-established patient experience questionnaire used in general practice in the UK since 2004. This new version can be recommended for use in order to meet the UK General Medical Council's requirements for surveys to be used in revalidation of doctors. It also meets the needs of GPs to ask about patient experience relating to aspects of practice care that are not specific to individual general practitioners (e.g. receptionists, telephone access) which meet other survey requirements of the National Health Service in England. Use of GPAQ-R has the potential to reduce the number of surveys that GPs need to carry out in their practices to meet the various regulatory requirements which they face. © 2013 Roland et al.; licensee BioMed Central Ltd.

Global biomass burning generates 40 million to 250 million tons of charcoal every year, part of which is preserved for millennia in soils and sediments. We have quantified dissolution products of charcoal in a wide range of rivers worldwide and show that globally, a major portion of the annual charcoal production is lost from soils via dissolution and subsequent transport to the ocean. The global flux of soluble charcoal accounts to 26.5 ± 1.8 million tons per year, which is ∼10% of the global riverine flux of dissolved organic carbon (DOC). We suggest that the mobilization of charcoal and DOC out of soils is mechanistically coupled. This study closes a major gap in the global charcoal budget and provides critical information in the context of geoengineering.

Due to projected increases in winter air temperatures in the northeastern USA over the next 100 years, the snowpack is expected to decrease in depth and duration, thereby increasing soil exposure to freezing air temperatures. To evaluate the potential physiological responses of sugar maple (Acer saccharum Marsh.) to a reduced snowpack, we measured root injury, foliar cation and carbohydrate concentrations, woody shoot carbohydrate levels, and terminal woody shoot lengths of trees in a snow manipulation experiment in New Hampshire, USA. Snow was removed from treatment plots for the first 6 weeks of winter for two consecutive years, resulting in lower soil temperatures to a depth of 50 cm for both winters compared to reference plots with an undisturbed snowpack. Visibly uninjured roots from trees in the snow removal plots had significantly higher (but sub-lethal) levels of relative electrolyte leakage than trees in the reference plots. Foliar calcium: aluminum (Al) molar ratios were significantly lower, and Al concentrations were significantly higher, in trees from snow removal plots than trees from reference plots. Snow removal also reduced terminal shoot growth and increased foliar starch concentrations. Our results are consistent with previous research implicating soil freezing as a cause of soil acidification that leads to soil cation imbalances, but are the first to show that this translates into altered foliar cation pools, and changes in soluble and structural carbon pools in trees. Increased soil freezing due to a reduced snowpack could exacerbate soil cation imbalances already caused by acidic deposition, and have widespread implications for forest health in the northeastern USA. © 2012 Springer-Verlag (outside the USA).

Background.: Adequate recruitment and retention rates are vital to achieving a successful randomized controlled trial. Historically this has been particularly challenging in mental health research. Few researchers have explored patients' reasons for taking part and remaining in a depression trial. Objective.: to explore patients' reasons for taking part and remaining in a trial that aimed to assess the effectiveness of cognitive behavioural therapy (CBT) as an adjunct to usual care for primary care patients with treatment resistant depression. Method.: (i) Design: Patients completed a short exit questionnaire about their experiences of taking part in the CoBalT trial. In addition, 40 semi-structured telephone interviews were conducted with a purposive sample of these patients to further explore their experiences. (ii) Setting: General practices, England and Scotland. Results.: of 469 patients randomized into the trial, 302 (64.4%) completed an exit questionnaire. The most frequently rated reason for taking part in the study were 'I was willing to try anything that might help me feel better' (66%). Patients indicated in interviews why they preferred follow-up data to be collected on a face-to-face basis rather than over the telephone. Some patients reported that taking part in the trial gave them a sense of self-worth and accomplishment. Conclusion.: Patients felt they benefited from being in the trial because it enabled them to reflect on their feelings. For some, taking part increased their feelings of self-worth. These findings may be applicable to trials where feelings of inclusion and being valued are likely to promote continued participation. © the Author 2013. Published by Oxford University Press.

Objective to document whether elements of a structured history and examination predict adverse outcome of acute sore throat. Design Prospective clinical cohort. Setting Primary care. Participants 14 610 adults with acute sore throat (≤2 weeks' duration). Main outcome measures Common suppurative complications (quinsy or peritonsillar abscess, otitis media, sinusitis, impetigo or cellulitis) and reconsultation with new or unresolving symptoms within one month. Results Complications were assessed reliably (inter-rater κ=0.95). 1.3% (177/13 445) of participants developed complications overall and 14.2% (1889/13 288) reconsulted with new or unresolving symptoms. Independent predictors of complications were severe tonsillar inflammation (documented among 13.0% (1652/12 717); odds ratio 1.92, 95% confidence interval 1.28 to 2.89) and severe earache (5% (667/13 323); 3.02, 1.91 to 4.76), but the model including both variables had modest prognostic utility (bootstrapped area under the receiver operator curve 0.61, 0.57 to 0.65), and 70% of complications (124/177) occurred when neither was present. Clinical prediction rules for bacterial infection (Centor criteria and FeverPAIN) also predicted complications, but predictive values were also poor and most complications occurred with low scores (67% (118/175) scoring ≤2 for Centor; 126/173 (73%) scoring ≤2 for FeverPAIN). Previous medical problems, sex, temperature, and muscle aches were independently but weakly associated with reconsultation with new or unresolving symptoms. Conclusion Important suppurative complications after an episode of acute sore throat in primary care are uncommon. History and examination and scores to predict bacterial infection cannot usefully identify those who will develop complications. Clinicians will need to rely on strategies such as safety netting or delayed prescription in managing the uncertainty and low risk of complications.

Background: Antidepressants are often the first-line treatment for depression in primary care. However, not all patients respond to medication after an adequate dose and duration of treatment. Currently, there are no estimates of the prevalence of treatment-resistant depression (TRD) from UK primary care. Aim: to estimate the prevalence of TRD in UK primary care. Design and setting: Data were collected as part of a multicentre randomised controlled trial, from 73 general practices in UK primary care. Method: Potential participants (aged 18-75 years who had received repeated prescriptions for antidepressants) were identified from general practice records. Those who agreed to be contacted were mailed a questionnaire that included questions on depressive symptoms (Beck Depression Inventory [BDI-II]), and adherence to antidepressants. Those who scored ≥14 on the BDI-II and had taken antidepressants for at least 6 weeks at an adequate dose were defined as treatment resistant. Results: a total of 2439 patients completed the questionnaire (84% of those who agreed to be contacted), of whom 2129 had been prescribed an adequate dose of antidepressants for at least 6 weeks. Seventy-seven per cent (95% CI = 75% to 79%) had a BDI score of ≥14. Fifty-five per cent (95% CI = 53% to 58%) (n = 1177) met the study's definition of TRD, of whom 67% had taken their antidepressants for more than 12 months. Conclusion: the high prevalence of TRD is an important challenge facing clinicians in UK primary care. A more proactive approach to managing this patient population is required to improve outcome. ©British Journal of General Practice.

This literature review focuses on what matters to young adults when they access primary care services in the United Kingdom. Patients' access to and experience of primary care services differs across age groups. Existing research has largely focused on the needs and experiences of children, adolescents, and adults. There is some evidence to suggest the views of young adults (aged 18-25 years) that may differ from the views of other age groups, and research has not previously reported specifically on the views of this group of the population. The literature was reviewed to identify the views and priorities of young UK adults regarding primary healthcare provision, and furthermore, to identify those related topics that would benefit from further research. Relevant academic publications and grey literature published from 2000 onwards was reviewed and synthesised. We identified and reported emerging themes that were of importance to young adults in respect of the UK primary care provision. A total of 19 papers met our inclusion criteria. Young adults access primary care services less frequently than other age groups; this may be because of their experience of primary care throughout childhood and adolescence. Five aspects of primary care provision emerged as being of importance to young adults--the accessibility and availability of services, the confidentiality of health-related information, issues relating to communication with healthcare professionals, continuity of care, and behaviours and attitudes expressed towards young adults by healthcare professionals. There is a lack of focus of current research on the expectations, needs, and primary healthcare experiences of young adults. Young adults may hold views that are distinct from other age groups. Further research is needed to better understand the needs of a young adult population as their needs may impact the future use of services.

Sensor networks are revolutionizing environmental monitoring by producing massive quantities of data that are being made publically available in near real time. These data streams pose a challenge for ecologists because traditional approaches to quality assurance and quality control are no longer practical when confronted with the size of these data sets and the demands of real-time processing. Automated methods for rapidly identifying and (ideally) correcting problematic data are essential. However, advances in sensor hardware have outpaced those in software, creating a need for tools to implement automated quality assurance and quality control procedures, produce graphical and statistical summaries for review, and track the provenance of the data. Use of automated tools would enhance data integrity and reliability and would reduce delays in releasing data products. Development of community-wide standards for quality assurance and quality control would instill confidence in sensor data and would improve interoperability across environmental sensor networks. © 2013 by American Institute of Biological Sciences.

Purpose Clinical quality and patient experience are both widely used to evaluate the quality of health care, but the relationship between these 2 domains remains uncertain. The aim of this study was to examine this relationship using data from 2 established measures of quality in primary care in England. Methods: Practice-level analyses (N = 7,759 practices in England) were conducted on measures of patient experience from the national General Practice Patient Survey (GPPS), and measures of clinical quality from the national pay-forperformance scheme (Quality and Outcomes Framework). Spearman's rank correlation and multiple linear regression were used on practice-level estimates. Results: Although all the correlations between clinical quality summary scores and patient survey scores are positive, and most are statistically significant, the strength of the associations was weak, with the highest correlation coefficient reaching 0.18, and more than one-half were 0.11 or less. Correlations with clinical quality were highest for patient-reported access scores (telephone access 0.16, availability of urgent appointments 0.15, ability to book ahead 0.18, ability to see preferred doctor 0.17) and overall satisfaction (0.15). Conclusion: Although there are associations between clinical quality and measures of patient experience, the 2 domains of care quality remain predominantly distinct. The strongest correlations are observed between practice clinical quality and practice access, with very low correlations between clinical quality and interpersonal aspects of care. The quality of clinical care and the quality of interpersonal care should be considered separately to give an overall assessment of medical care.

Study question: Does facilitated physical activity provide an effective treatment for adults with depression presenting in primary care? Summary answer: Although trial participants receiving the physical activity intervention in addition to usual care reported increased physical activity compared with those receiving usual care alone, there was no evidence to suggest that the intervention brought about any improvement in depressive symptoms or reduction in antidepressant use. What is known and what this paper adds: Numerous studies have reported the positive effects of physical activity, but most of the current evidence originates from small non-clinical samples using interventions that are not practicable in a healthcare setting. Our results indicate that offering patients a facilitated physical activity intervention is not an effective strategy for reducing symptoms of depression, although it increased self reported physical activity and sustained this effect over 12 months.

INTRODUCTION: Multisource feedback (MSF) ratings provided by patients and colleagues are often poorly correlated with doctors' self-assessments. Doctors' reactions to feedback depend on its agreement with their own perceptions, but factors influencing self-other agreement in doctors' MSF ratings have received little attention. We aimed to identify the characteristics of doctors and their rater groups that affect self-other agreement in MSF ratings. METHODS: We invited 2454 doctors to obtain patient and colleague feedback using the UK General Medical Council's MSF questionnaires and to self-assess on core items from both patient (PQ) and colleague (CQ) questionnaires. Correlations and differences between doctor, patient and colleague mean feedback scores were examined. Regression analyses identified the characteristics of doctors and their rater groups that influenced self-other score agreement. RESULTS: 1065 (43%) doctors returned at least one questionnaire, of whom 773 (73%) provided self and patient PQ scores and 1026 (96%) provided self and colleague CQ scores. Most doctors rated themselves less favourably than they were rated by either their patients or their colleagues. This tendency to underrate performance in comparison to external feedback was influenced by the doctor's place of training, clinical specialty, ethnicity and the profile of his/her patient and colleague rater samples but, in contrast to studies undertaken in nonmedical settings, was unaffected by age or gender. DISCUSSION: Self-other agreement in MSF ratings is influenced by characteristics of both raters and ratees. Managers, appraisers, and others responsible for interpreting and reviewing feedback results with the doctor need to be aware of these influences.

BACKGROUND: Recent years have seen an increase in primary care workload, especially following the introduction of a new General Medical Services contract in 2004. Telephone triage and telephone consultation with patients seeking health care represent initiatives aimed at improving access to care. Some evidence suggests that such approaches may be feasible but conclusions regarding GP workload, cost, and patients' experience of care, safety, and health status are equivocal. The ESTEEM trial aims to assess the clinical- and cost-effectiveness of nurse-led computer-supported telephone triage and GP-led telephone triage, compared to usual care, for patients requesting same-day consultations in general practice. METHODS/DESIGN: ESTEEM is a pragmatic, multi-centre cluster randomised clinical trial with patients randomised at practice level to usual care, computer decision-supported nurse triage, or GP-led triage. Following triage of 350-550 patients per practice we anticipate estimating and comparing total primary care workload (volume and time), the economic cost to the NHS, and patient experience of care, safety, and health status in the 4-week period following the index same-day consultation request across the three trial conditions.We will recruit all patients seeking a non-emergency same-day appointment in primary care. Patients aged 12.0-15.9 years and temporary residents will be excluded from the study.The primary outcome is the number of healthcare contacts taking place in the 4-week period following (and including) the index same-day consultation request. A range of secondary outcomes will be examined including patient flow, primary care NHS resource use, patients' experience of care, safety, and health status.The estimated sample size required is 3,751 patients (11,253 total) in each of the three trial conditions, to detect a mean difference of 0.36 consultations per patient in the four week follow-up period between either intervention group and usual care 90% power, 5% alpha, and an estimated intracluster correlation coefficient ICC of 0.05. The primary analysis will be based on the intention-to-treat principle and take the form of a random effects regression analysis taking account of the hierarchical nature of the study design. Statistical models will allow for adjustment for practice level minimisation variables and patient-level baseline covariates shown to differ at baseline.

BACKGROUND: Young adulthood is an important transitional period during which there is a higher risk of individuals engaging in behaviours which could have a lasting impact on their health. Research has shown that young adults are the lowest responders to surveys about healthcare experiences and are also the least satisfied with the care they receive. However, the factors contributing to this reduced satisfaction are not clear. The focus of our research was to explore the needs and experiences of young adults around healthcare services with an aim of finding out possible reasons for lower satisfaction. METHODS: Twenty young adults were interviewed at GP surgeries and at a local young adult advice agency, exploring their experiences and use of primary care services. Interviews were analysed using thematic analysis. RESULTS: the use of primary care services varied amongst the young adult interviewees. Many interviewees reported positive experiences; those who did not linked their negative experiences to difficulties in negotiating their care with the health care system, and reported issues with trust, and communication difficulties. Most of the interviewees were unaware of the use of patient surveys to inform healthcare planning and delivery and were not inclined to take part, mainly because of the length of surveys and lack of interest in the topic area. CONCLUSIONS: in order to effectively address the health needs of young adults, young adults need to be educated about their rights as patients, and how to most efficiently use primary care services. GPs should be alert to effective means of approaching and handling the healthcare needs of young adults. A flexible, varied approach is needed to gathering high quality data from this group in order to provide services with information on the changes necessary for making primary care services more accessible for young adults.

Objective: the TREAting Depression with physical activity (TREAD) study investigated the cost-effectiveness of a physical activity intervention, in addition to usual general practitioner care, as a treatment for people with depression. Design: an individually randomised, pragmatic, multicentre randomised controlled trial with follow-up at 4, 8 and 12 months. A subset of participants took part in a qualitative study that investigated the acceptability and perceived benefits of the intervention. Setting: General practices in the Bristol and Exeter areas. Participants: Aged 18-69 years with an International Statistical Classification of Diseases and Related Health Problems, 10th Edition (ICD-10) diagnosis of depression and scoring ≥ 14 on the Beck Depression Inventory (BDI). Those who were unable to complete selfadministered questionnaires in English, with medical contraindications to physical activity or with psychosis, bipolar disorder or serious drug abuse were excluded. Interventions: We devised an intervention designed to encourage choice and autonomy in the adoption of physical activity. It consisted of up to three face-to-face and ten telephone contacts delivered by a trained physical activity facilitator over an 8-month period. Main outcome measures: the primary outcome was the BDI score measured at 4 months. Secondary outcomes included depressive symptoms over the 12 months and quality of life, antidepressant use and level of physical activity. Results: the study recruited 361 patients, with 182 randomised to the intervention arm and 179 to the usual care arm; there was 80% retention at the 4-month follow-up. The intervention group had a slightly lower BDI score at 4 months [-0.54, 95% confidence interval (CI) -3.06 to 1.99] but there was no evidence that the intervention improved outcome for depression. Neither was there any evidence to suggest a difference in the prescription of or self-reported use of antidepressants. However, the amount of physical activity undertaken by those who had received the intervention was increased (odds ratio 2.3, 95% CI 1.3 to 3.9) and was sustained beyond the end of the intervention. From a health-care perspective, the intervention group was more costly than the usual care group, with the cost of the intervention £220 per person on average. It is therefore extremely unlikely that the intervention is cost-effective as a treatment for depression using current willingness-to-pay thresholds. Conclusions: This physical activity intervention is very unlikely to lead to any clinical benefit in terms of depressive symptoms or to be a cost-effective treatment for depression. Previous research has reported some benefit and there are three possible reasons for this discrepancy: first, even though the intervention increased self-reported physical activity, the increase in activity was not sufficiently large to lead to a measurable influence; second, only more vigorous activity might be of benefit; and third, previous studies had recruited individuals with a pre-existing commitment to physical activity. Future research is needed to identify and explain the mechanisms by which depression might be effectively treated, including, in particular, specific guidance on the optimum type, intensity and duration of physical activity required to produce a therapeutic effect.

BACKGROUND: People with Parkinson's (PwP) experience frequent and recurrent falls. As these falls may have devastating consequences, there is an urgent need to identify cost-effective interventions with the potential to reduce falls in PwP. The purpose of this economic evaluation is to compare the costs and cost-effectiveness of a targeted exercise programme versus usual care for PwP who were at risk of falling. METHODS: One hundred and thirty participants were recruited through specialist clinics, primary care and Parkinson's support groups and randomised to either an exercise intervention or usual care. Health and social care utilisation and health-related quality of life (EQ-5D) were assessed over the 20 weeks of the study (ten-week intervention period and ten-week follow up period), and these data were complete for 93 participants. Incremental cost per quality adjusted life year (QALY) was estimated. The uncertainty around costs and QALYs was represented using cost-effectiveness acceptability curves. RESULTS: the mean cost of the intervention was £76 per participant. Although in direction of favour of exercise intervention, there was no statistically significant differences between groups in total healthcare (-£128, 95% CI: -734 to 478), combined health and social care costs (£-35, 95% CI: -817 to 746) or QALYs (0.03, 95% CI: -0.02 to 0.03) at 20 weeks. Nevertheless, exploration of the uncertainty surrounding these estimates suggests there is more than 80% probability that the exercise intervention is a cost-effective strategy relative to usual care. CONCLUSION: Whilst we found no difference between groups in total healthcare, total social care cost and QALYs, analyses indicate that there is high probability that the exercise intervention is cost-effective compared with usual care. These results require confirmation by larger trial-based economic evaluations and over the longer term.

Background: Only one-third of patients with depression respond fully to antidepressant medication but there is little evidence regarding the best ‘next step’ treatment for those whose symptoms are ‘treatment resistant’. The CoBalT trial examined the effectiveness of CBT as an adjunct to usual care (including pharmacotherapy) for primary care patients with treatment resistant depression (TRD) compared with usual care alone.
Methods:. This two parallel-group multi-centre randomised controlled trial recruited 469 patients with TRD (on antidepressants for ≥6 weeks, Beck Depression Inventory (BDI) score ≥14 and ICD-10 criteria for depression) from 73 UK general practices. Participants were randomised, using a computer generated code, to one of two groups: usual care (n = 235) or CBT in addition to usual care (n = 234), and were followed up for 12 months. The primary outcome was ‘response’, defined as ≥50% reduction in depressive symptoms (BDI score) at 6 months compared to baseline. Trial registration was ISRCTN38231611.
Findings: 422 participants (90%) were followed up at 6 months and 396 (84%) at 12 months. 95 participants (46.1%) in the intervention group met criteria for ‘response’ at 6 months compared with 46 (21.6%) in the usual care group (odds ratio (OR): 3.26 (95%CI: 2.10, 5.06) p

BACKGROUND: Antidepressants are often the first-line treatment for depression but only one third of patients respond fully to pharmacotherapy. This paper describes the protocol for a randomised controlled trial (RCT) designed to evaluate the clinical and cost effectiveness of cognitive behavioural therapy (CBT) as an adjunct to pharmacotherapy for patients with treatment resistant depression in primary care. METHODS/DESIGN: CoBalT is a two parallel group multi-centre pragmatic RCT. Eligible participants were those who: (i) were aged 18-75years; (ii) were currently taking antidepressant medication (for at least 6weeks at an adequate dose); (iii) scored ≥14 on the Beck Depression Inventory (BDI-II); (iv) had adhered to their medication; and (v) met ICD-10 criteria for depression (assessed using the Clinical Interview Schedule - revised version). Those who gave written informed consent were randomised to one of two treatment groups: usual care or usual care plus CBT. The primary outcome is depressive symptoms assessed using the BDI-II at 6months post-randomisation. Secondary outcomes measured at 6 and 12months include quality of life, antidepressant use and health care utilisation. Outcomes will be analysed on an intention-to-treat basis. DISCUSSION: the CoBalT trial will provide evidence on the clinical and cost effectiveness of CBT as an adjunct to antidepressant medication in the treatment of depression that has not responded to pharmacotherapy. Given the move to widen access to 'talking therapies', the results of this study will be timely.

Background: Interpersonal continuity of care is valued by patients, but there is concern that it has declined in recent years. Aim: to determine how often patients express preference for seeing a particular GP and the extent to which that preference is met. Design of study: Analysis of data from the 2009/2010 English GP Patient Survey. Setting: a stratified random sample of adult patients registered with 8362 general practices in England (response rate 39%, yielding 2 169 718 responses). Method: Weighted estimates were calculated of preference for and success in seeing a particular GP. Multilevel logistic regression was used to identify characteristics associated with these two outcomes. Results: Excluding practices with one GP, 62% of patients expressed a preference for seeing a particular GP. of these patients, 72% were successful in seeing their preferred GP most of the time. Certain patient groups were associated with more preference for and success in seeing a particular GP. These were older patients (preference odds ratio [OR] = 1.7, success OR = 1.8), those with chronic medical conditions (preference OR = 1.9, success OR = 1.3), those with chronic psychological conditions (preference OR = 1.6, success OR = 1.3), and those recently requesting only non-urgent versus urgent appointments (preference OR = 1.4, success OR = 1.6). Patient groups that had more frequent preference but less success in seeing a preferred GP were females (preference OR = 1.5, success OR = 0.9), patients in larger practices (preference OR = 1.3, success OR = 0.5), and those belonging to non-white ethnic groups. Conclusion: the majority of patients value interpersonal continuity, yet a large minority of patients and specific patient groups are not regularly able to see the GP they prefer. ©British Journal of General Practice.

Analyses of long-term records at 35 headwater basins in the United States and Canada indicate that climate change effects on streamflow are not as clear as might be expected, perhaps because of ecosystem processes and human influences. Evapotranspiration was higher than was predicted by temperature in water-surplus ecosystems and lower than was predicted in water-deficit ecosystems. Streamflow was correlated with climate variability indices (e.g. the El Niño-Southern Oscillation, the Pacific Decadal Oscillation, the North Atlantic Oscillation), especially in seasons when vegetation influences are limited. Air temperature increased significantly at 17 of the 19 sites with 20-to 60-year records, but streamflow trends were directly related to climate trends (through changes in ice and snow) at only 7 sites. Past and present human and natural disturbance, vegetation succession, and human water use can mimic, exacerbate, counteract, or mask the effects of climate change on streamflow, even in reference basins. Long-term ecological research sites are ideal places to disentangle these processes. © 2012 by American Institute of Biological Sciences. All rights reserved.

Objective: to investigate the effectiveness of facilitated physical activity as an adjunctive treatment for adults with depression presenting in primary care. Design: Pragmatic, multicentre, two arm parallel randomised controlled trial. Setting: General practices in Bristol and Exeter. Participants: 361 adults aged 18-69 who had recently consulted their general practitioner with symptoms of depression. All those randomised had a diagnosis of an episode of depression as assessed by the clinical interview schedule-revised and a Beck depression inventory score of 14 or more. Interventions: in addition to usual care, intervention participants were offered up to three face to face sessions and 10 telephone calls with a trained physical activity facilitator over eight months. The intervention was based on theory and aimed to provide individually tailored support and encouragement to engage in physical activity. Main outcome measures: the primary outcome was self reported symptoms of depression, assessed with the Beck depression inventory at four months post-randomisation. Secondary outcomes included use of antidepressants and physical activity at the four, eight, and 12 month follow-up points, and symptoms of depression at eight and 12 month follow-up. Results: There was no evidence that participants offered the physical activity intervention reported improvement in mood by the four month follow-up point compared with those in the usual care group; adjusted between group difference in mean Beck depression inventory score -0.54 (95% confidence interval -3.06 to 1.99; P=0.68). Similarly, there was no evidence that the intervention group reported a change in mood by the eight and 12 month follow-up points. Nor was there evidence that the intervention reduced antidepressant use compared with usual care (adjusted odds ratio 0.63, 95% confidence interval 0.19 to 2.06; P=0.44) over the duration of the trial. However, participants allocated to the intervention group reported more physical activity during the follow-up period than those allocated to the usual care group (adjusted odds ratio 2.27, 95% confidence interval 1.32 to 3.89; P=0.003). Conclusions: the addition of a facilitated physical activity intervention to usual care did not improve depression outcome or reduce use of antidepressants compared with usual care alone.

Objectives: Clinical guidance recommends physical activity for patients with persistent sub-threshold depressive symptoms or mild to moderate depression. However, little is known regarding how General Practitioners (GPs) view physical activity as a treatment for depression. This is the first study to explore GPs' views of physical activity, the extent of promotion of physical activity within the course of consultations, and awareness of evidence and clinical guidance for physical activity as a treatment for depression. Methods: Qualitative study using semi-structured interviews with 15 General Practitioners from practices participating in a randomised controlled trial of facilitated physical activity for depression in primary care. Results: Most GPs felt that physical activity could be an effective treatment for depression but referred to anecdotal rather than research evidence to support its promotion in primary care. Most GPs thought that physical activity was best promoted as an adjunct to antidepressant medication. GPs also stated that many patients were looking for alternative approaches to treating depression but were also aware of many barriers to physical activity. Conclusion: GPs are enthusiastic about promoting physical activity for the management of depression and may do so without reference to an evidence base. The findings have implications for clinical guidelines regarding the recommendation of physical activity for patients with depression. GPs should explore both patients' perceptions of physical activity as a treatment and their ability to engage with physical activity prior to recommending physical activity for the management of depressive symptoms in primary care. © 2012 Elsevier Ltd.

Legacy effects of past land use and disturbance are increasingly recognized, yet consistent definitions of and criteria for defining them do not exist. To address this gap in biological-and ecosystem-assessment frameworks, we propose a general metric for evaluating potential legacy effects, which are computed by normalizing altered system function persistence with duration of disturbance. We also propose two distinct legacy-effect categories: signal effects from lags in transport and structural effects from physical landscape changes. Using flux records for water, sediment, nitrogen, and carbon from long-term study sites in the eastern United States from 1500 to 2000, we identify gaps in our understanding of legacy effects and reveal that changes in basin sediment dynamics precede instrumented records. These sediment dynamics are not generally incorporated into interpretations of contemporary records, although their potential legacy effects are substantial. The identification of legacy effects may prove to be a fundamental component of landscape management and effective conservation and restoration practice. © 2012 by American Institute of Biological Sciences.

Background: the effectiveness of exercise referral schemes (ERS) is influenced by uptake and adherence to the scheme. The identification of factors influencing low uptake and adherence could lead to the refinement of schemes to optimise investment. Objectives: to quantify the levels of ERS uptake and adherence and to identify factors predictive of uptake and adherence. Methods: a systematic review and meta-analysis was undertaken. MEDLINE, EMBASE, PsycINFO, Cochrane Library, ISI WOS, SPORTDiscus and ongoing trial registries were searched (to October 2009) and included study references were checked. Included studies were required to report at least one of the following: (1) a numerical measure of ERS uptake or adherence and (2) an estimate of the statistical association between participant demographic or psychosocial factors (eg, level of motivation, self-efficacy) or programme factors and uptake or adherence to ERS. Results: Twenty studies met the inclusion criteria, six randomised controlled trials (RCTs) and 14 observational studies. The pooled level of uptake in ERS was 66% (95% CI 57% to 75%) across the observational studies and 81% (95% CI 68% to 94%) across the RCTs. The pooled level of ERS adherence was 49% (95% CI 40% to 59%) across the observational studies and 43% (95% CI 32% to 54%) across the RCTs. Few studies considered anything other than gender and age. Women were more likely to begin an ERS but were less likely to adhere to it than men. Older people were more likely to begin and adhere to an ERS. Limitations: Substantial heterogeneity was evident across the ERS studies. Without standardised definitions, the heterogeneity may have been reflective of differences in methods of defining uptake and adherence across studies. Conclusions: to enhance our understanding of the variation in uptake and adherence across ERS and how these variations might affect physical activity outcomes, future trials need to use quantitative and qualitative methods.

Evaluations of the local effects of global change are often confounded by the interactions of natural and anthropogenic factors that overshadow the effects of climate changes on ecosystems. Long-term watershed and natural elevation gradient studies at the Hubbard Brook Experimental Forest and in the surrounding region show surprising results demonstrating the effects of climate change on hydrologic variables (e.g. evapotranspiration, streamflow, soil moisture); the importance of changes in phenology on water, carbon, and nitrogen fluxes during critical seasonal transition periods; winter climate change effects on plant and animal community composition and ecosystem services; and the effects of anthropogenic disturbances and land-use history on plant community composition. These studies highlight the value of long-term integrated research for assessments of the subtle effects of changing climate on complex ecosystems. © 2012 by American Institute of Biological Sciences.

Purpose: Internationally, there is increasing interest in monitoring and evaluating doctors’ professional practice. Multisource feedback (MSF) offers one way of collecting information about a doctor’s performance. The authors investigated the psychometric properties of two questionnaires developed for this purpose, and explored the biases that may exist within data collected via such instruments.
Method: a cross-sectional study was conducted in 11 UK health care organisations during 2008-2011. Patients (n = 30,333) and colleagues (n = 17,012) rated the professional performance of 1,065 practising doctors, using the General Medical Council (GMC) Patient Questionnaire (PQ) and Colleague Questionnaire (CQ). The psychometric properties of the questionnaires were assessed and regression modelling was used to explore factors that influenced patient and colleague responses on the core questionnaire items.
Results: Although the questionnaires demonstrated satisfactory internal consistency, test-retest reliability, and convergent validity, patient and colleague ratings were highly skewed towards favourable impressions of doctor performance. At least 34 PQs and 15 CQs were required to achieve acceptable reliability (G > 0.70). Item ratings were influenced by characteristics of the patient and colleague respondents and the context in which their feedback was provided.
Conclusions: the PQ and CQ are acceptable for the provision of formative feedback on a doctor’s professional practice within an appraisal process. However, biases identified in the questionnaire data suggest that caution is required when interpreting and acting on this type of information. MSF derived from these questionnaires should not be used in isolation to inform decisions about a doctor’s fitness to practise medicine.

BACKGROUND: UK revalidation plans for doctors include obtaining multisource feedback from patient and colleague questionnaires as part of the supporting information for appraisal and revalidation. AIM: to investigate GPs' and appraisers' views of using multisource feedback data in appraisal, and of the emerging links between multisource feedback, appraisal, and revalidation. DESIGN AND SETTING: a qualitative study in UK general practice. METHOD: in total, 12 GPs who had recently completed the General Medical Council multisource feedback questionnaires and 12 appraisers undertook a semi-structured, telephone interview. A thematic analysis was performed. RESULTS: Participants supported multisource feedback for formative development, although most expressed concerns about some elements of its methodology (for example, 'self' selection of colleagues, or whether patients and colleagues can provide objective feedback). Some participants reported difficulties in understanding benchmark data and some were upset by their scores. Most accepted the links between appraisal and revalidation, and that multisource feedback could make a positive contribution. However, tensions between the formative processes of appraisal and the summative function of revalidation were identified. CONCLUSION: Participants valued multisource feedback as part of formative assessment and saw a role for it in appraisal. However, concerns about some elements of multisource feedback methodology may undermine its credibility as a tool for identifying poor performance. Proposals linking multisource feedback, appraisal, and revalidation may limit the use of multisource feedback and appraisal for learning and development by some doctors. Careful consideration is required with respect to promoting the accuracy and credibility of such feedback processes so that their use for learning and development, and for revalidation, is maximised.

Objectives: Uncertainties exist about when and how best to adjust performance measures for case mix. Our aims are to quantify the impact of case-mix adjustment on practice-level scores in a national survey of patient experience, to identify why and when it may be useful to adjust for case mix, and to discuss unresolved policy issues regarding the use of case-mix adjustment in performance measurement in health care. Design/setting: Secondary analysis of the 2009 English General Practice Patient Survey. Responses from 2 163 456 patients registered with 8267 primary care practices. Linear mixed effects models were used with practice included as a random effect and five case-mix variables (gender, age, race/ethnicity, deprivation, and self-reported health) as fixed effects. Main outcome measures: Primary outcome was the impact of case-mix adjustment on practice-level means (adjusted minus unadjusted) and changes in practice percentile ranks for questions measuring patient experience in three domains of primary care: access; interpersonal care; anticipatory care planning, and overall satisfaction with primary care services. Results: Depending on the survey measure selected, case-mix adjustment changed the rank of between 0.4% and 29.8% of practices by more than 10 percentile points. Adjusting for case-mix resulted in large increases in score for a small number of practices and small decreases in score for a larger number of practices. Practices with younger patients, more ethnic minority patients and patients living in more socio-economically deprived areas were more likely to gain from case-mix adjustment. Age and race/ethnicity were the most influential adjustors. Conclusions: While its effect is modest for most practices, case-mix adjustment corrects significant underestimation of scores for a small proportion of practices serving vulnerable patients and may reduce the risk that providers would 'cream-skim' by not enrolling patients from vulnerable socio-demographic groups.

OBJECTIVE: to determine whether a difference in systolic blood pressure readings between arms can predict a reduced event free survival after 10 years. DESIGN: Cohort study. SETTING: Rural general practice in Devon, United Kingdom. PARTICIPANTS: 230 people receiving treatment for hypertension in primary care. INTERVENTION: Bilateral blood pressure measurements recorded at three successive surgery attendances. MAIN OUTCOME MEASURES: Cardiovascular events and deaths from all causes during a median follow-up of 9.8 years. RESULTS: at recruitment 24% (55/230) of participants had a mean interarm difference in systolic blood pressure of 10 mm Hg or more and 9% (21/230) of 15 mm Hg or more; these differences were associated with an increased risk of all cause mortality (adjusted hazard ratio 3.6, 95% confidence interval 2.0 to 6.5 and 3.1, 1.6 to 6.0, respectively). The risk of death was also increased in 183 participants without pre-existing cardiovascular disease with an interarm difference in systolic blood pressure of 10 mm Hg or more or 15 mm Hg or more (2.6, 1.4 to 4.8 and 2.7, 1.3 to 5.4). An interarm difference in diastolic blood pressure of 10 mm Hg or more was weakly associated with an increased risk of cardiovascular events or death. CONCLUSIONS: Differences in systolic blood pressure between arms can predict an increased risk of cardiovascular events and all cause mortality over 10 years in people with hypertension. This difference could be a valuable indicator of increased cardiovascular risk. Bilateral blood pressure measurements should become a routine part of cardiovascular assessment in primary care.

The cryosphere-the portion of the Earth's surface where water is in solid form for at least one month of the year-has been shrinking in response to climate warming. The extents of sea ice, snow, and glaciers, for example, have been decreasing. In response, the ecosystems within the cryosphere and those that depend on the cryosphere have been changing. We identify two principal aspects of ecosystem-level responses to cryosphere loss: (1) trophodynamic alterations resulting from the loss of habitat and species loss or replacement and (2) changes in the rates and mechanisms of biogeochemical storage and cycling of carbon and nutrients, caused by changes in physical forcings or ecological community functioning. These changes affect biota in positive or negative ways, depending on how they interact with the cryosphere. The important outcome, however, is the change and the response the human social system (infrastructure, food, water, recreation) will have to that change. © 2012 by American Institute of Biological Sciences.

Background: Ethnic minorities and some other patient groups consistently report lower scores on patient surveys, but the reasons for this are unclear. This study examined whether low scores of ethnic minority and other socio-demographic groups reflect their concentration in poorly performing primary care practices, and whether any remaining differences are consistent across practices. Methods: Using data from the 2009 English General Practice Patient Survey (2 163 456 respondents from 8267 general practices) this study examined associations between patient socio-demographic characteristics and 11 measures of patient-reported experience. Findings: South Asian and Chinese patients, younger patients, and those in poor health reported a less positive primary care experience than White patients, older patients and those in better health. For doctor communication, about half of the overall difference associated with South Asian patients (ranging from -6 to -9 percentage points) could be explained by their concentration in practices with low scores, but the other half arose because they reported less positive experiences than White patients in the same practices. Practices varied considerably in the direction and extent of ethnic differences. In some practices ethnic minority patients reported better experience than White patients. Differences associated with gender, Black ethnicity and deprivation were small and inconsistent. Conclusion: Substantial ethnic differences in patient experience exist in a national healthcare system providing universal coverage. Improving the experience of patients in low-scoring practices would not only improve the quality of care provided to their White patients but it would also substantially reduce ethnic group differences in patient experience. There were large variations in the experiences reported by ethnic minority patients in different practices: practices with high patient experience scores from ethnic minority patients could be studied as models for quality improvement.

BACKGROUND: Social isolation affects a significant proportion of older people and is associated with poor health outcomes. The current evidence base regarding the effectiveness of interventions targeting social isolation is poor, and the potential utility of mentoring for this purpose has not previously been rigorously evaluated. The purpose of this study was to examine the effectiveness of a community-based mentoring service for improving mental health, social engagement and physical health for socially isolated older people. METHODS: This prospective controlled trial compared a sample of mentoring service clients (intervention group) with a matched control group recruited through general practice. One hundred and ninety five participants from each group were matched on mental wellbeing and social activity scores. Assessments were conducted at baseline and at six month follow-up. The primary outcome was the Short Form Health Survey v2 (SF-12) mental health component score (MCS). Secondary outcomes included the SF-12 physical health component score (PCS), EuroQol EQ-5D, Geriatric Depression Score (GDS-10), social activity, social support and morbidities. RESULTS: We found no evidence that mentoring was beneficial across a wide range of participant outcomes measuring health status, social activity and depression. No statistically significant between-group differences were observed at follow-up in the primary outcome (p = 0.48) and in most secondary outcomes. Identifying suitable matched pairs of intervention and control group participants proved challenging. CONCLUSIONS: the results of this trial provide no substantial evidence supporting the use of community mentoring as an effective means of alleviating social isolation in older people. Further evidence is needed on the effectiveness of community-based interventions targeting social isolation. When using non-randomised designs, there are considerable challenges in the recruitment of suitable matches from a community sample.

Objectives: to compare the effectiveness of an exercise programme with usual care in people with Parkinson's disease (PD) who have a history of falls. Design: Pragmatic randomised controlled trial. Setting: Recruitment was from three primary and four secondary care organisations, and PD support groups in South West England. The intervention was delivered in community settings. Participants: People with PD, with a history of two or more falls in the previous year, who were able to mobilise independently. Intervention: 10 week, physiotherapy led, group delivered strength and balance training programme with supplementary home exercises (intervention) or usual care (control). Main outcome measure: Number of falls during the (a) 10 week intervention period and (b) the 10 week followup period. Results: 130 people were recruited and randomised (64 to the intervention; 66 to usual care). Seven participants (5.4%) did not complete the study. The incidence rate ratio for falls was 0.68 (95% CI 0.43 to 1.07, p=0.10) during the intervention period and 0.74 (95% CI 0.41 to 1.33, p=0.31) during the follow-up period. Statistically significant between group differences were observed in Berg balance, Falls Efficacy Scale-International scores and recreational physical activity levels. Conclusions: the study did not demonstrate a statistically significant between group difference in falls although the difference could be considered clinically significant. However, a type 2 error cannot be ruled out. The findings from this trial add to the evidence base for physiotherapy and exercise in the management of people with PD.

Windblown and vehicle-raised dust from unvegetated mine tailings can be a human health risk. Airborne particles from As-rich abandoned Au mine tailings from Nova Scotia, Canada have been characterized in terms of particle size, As concentration, As oxidation state, mineral species and texture. Samples were collected in seven aerodynamically fractionated size ranges (0.5-16μm) using a cascade impactor deployed at three tailings fields. All three sites are used for recreational activities and off-road vehicles were racing on the tailings at two mines during sample collection. Total concentrations of As in the

AIM: to examine whether different methods of administration of a patient questionnaire (PQ) assessing a doctor's professional performance can influence the quality of data collected. BACKGROUND: Patient surveys are important information sources regarding a doctor's professional performance. Previous research across a range of patient outcomes suggests that the method of administration can influence response rates and ratings, although no data that explore how this might influence patients' assessments of a doctor's professional performance are available. METHODS: a volunteer sample of 13 UK doctors from primary care settings undertook a cross-sectional patient survey. Seven doctors distributed patient surveys using exit and touch-tone telephone administration, and six doctors used exit and postal administration. A consecutive sample of up to 40 patients per doctor completed each method of administration; postal and touch-tone surveys were administered retrospectively, whereas the exit surveys were administered prospectively. The GMC (General Medical Council) PQ included nine performance evaluation questions. We examined the response rates, item completion rates and response profiles of exit survey responses with those obtained from either postal or touch-tone telephone methods. RESULTS: the administration methods influence the quality and comparability of data obtained. The exit survey response rate was higher than touch-tone (82.1% versus 37.5%; P < 0.0001) or postal survey (no reminder) (76.7% versus 60.8%; P < 0.0001) administration, but comparable to the postal survey after one reminder (78.3% versus 75.0%; P = 0.39). Item completion rates were comparable for exit and touch-tone surveys (highest rates of missing data 4.1% and 4.6%, respectively), but exit surveys resulted in more missing values than postal surveys (10.3 to 11.7% versus 1.1 to 3.9%). Response profiles varied. Both touch-tone and postal surveys yielded significantly more critical ratings than the exit survey (three of nine items). CONCLUSION: Mixing administration methods requires caution when the data are used to create benchmarks against which a doctor's performance is assessed.

Objective: to assess the impact of exercise referral schemes on physical activity and health outcomes. Design: Systematic review and meta-analysis. Data sources: Medline, Embase, PsycINFO, Cochrane Library, ISI Web of Science, SPORTDiscus, and ongoing trial registries up to October 2009. We also checked study references. Study selection: Design: randomised controlled trials or non-randomised controlled (cluster or individual) studies published in peer review journals. Population: sedentary individuals with or without medical diagnosis. Exercise referral schemes defined as: clear referrals by primary care professionals to third party service providers to increase physical activity or exercise, physical activity or exercise programmes tailored to individuals, and initial assessment and monitoring throughout programmes. Comparators: usual care, no intervention, or alternative exercise referral schemes. Results: Eight randomised controlled trials met the inclusion criteria, comparing exercise referral schemes with usual care (six trials), alternative physical activity intervention (two), and an exercise referral scheme plus a self determination theory intervention (one). Compared with usual care, follow-up data for exercise referral schemes showed an increased number of participants who achieved 90-150 minutes of physical activity of at least moderate intensity per week (pooled relative risk 1.16, 95% confidence intervals 1.03 to 1.30) and a reduced level of depression (pooled standardised mean difference -0.82, -1.28 to -0.35). Evidence of a between group difference in physical activity of moderate or vigorous intensity or in other health outcomes was inconsistent at follow-up. We did not find any difference in outcomes between exercise referral schemes and the other two comparator groups. None of the included trials separately reported outcomes in individuals with specific medical diagnoses. Substantial heterogeneity in the quality and nature of the exercise referral schemes across studies might have contributed to the inconsistency in outcome findings. Conclusions: Considerable uncertainty remains as to the effectiveness of exercise referral schemes for increasing physical activity, fitness, or health indicators, or whether they are an efficient use of resources for sedentary people with or without a medical diagnosis.

Objectives: to investigate potential sources of systematic bias arising in the assessment of doctors' professionalism. Design: Linear regression modelling of cross sectional questionnaire survey data. Setting: 11 clinical practices in England and Wales. Participants: 1065 non-training grade doctors from various clinical specialties and settings, 17 031 of their colleagues, and 30 333 of their patients. Main outcome measures: Two measures of a doctor's professional performance using patient and colleague questionnaires from the United Kingdom's General Medical Council (GMC). We selected potential predictor variables from the characteristics of the doctors and of their patient and colleague assessors. Results: After we adjusted for characteristics of the doctor as well as characteristics of the patient sample, less favourable scores from patient feedback were independently predicted by doctors having obtained their primary medical degree from any non-European country; doctors practising as a psychiatrist; lower proportions of white patients providing feedback; lower proportions of patients rating their consultation as being very important; and lower proportions of patients reporting that they were seeing their usual doctor. Lower scores from colleague feedback were independently predicted by doctors having obtained their primary medical degree from countries outside the UK and South Asia; currently employed in a locum capacity; working as a general practitioner or psychiatrist; being employed in a staff grade, associate specialist, or other equivalent role; and with a lower proportion of colleagues reporting they had daily or weekly professional contact with the doctor. In fully adjusted models, the doctor's age, sex, and ethnic group were not independent predictors of patient or colleague feedback. Neither the age or sex profiles of the patient or colleague samples were independent predictors of doctors' feedback scores, and nor was the ethnic group of colleague samples. Conclusions: Caution is necessary when considering patient and colleague feedback regarding doctors' professionalism. Multisource feedback undertaken for revalidation using the GMC patient and colleague questionnaires should, at least initially, be principally formative in nature.

Patient experience is increasingly used to assess organizational performance, for example in public reporting or pay-for-performance schemes. Conventional approaches using 95% confidence intervals are commonly used to determine required survey samples or to report performance but these may result in unreliable organizational comparisons.

BACKGROUND: Targeting social isolation in older people is a growing public health concern. The proportion of older people in society has increased in recent decades, and it is estimated that approximately 25% of the population will be aged 60 or above within the next 20 to 40 years. Social isolation is prevalent amongst older people and evidence indicates the detrimental effect that it can have on health and wellbeing. The aim of this review was to assess the effectiveness of interventions designed to alleviate social isolation and loneliness in older people. METHODS: Relevant electronic databases (MEDLINE, EMBASE, ASSIA, IBSS, PsycINFO, PubMed, DARE, Social Care Online, the Cochrane Library and CINAHL) were systematically searched using an extensive search strategy, for randomised controlled trials and quasi-experimental studies published in English before May 2009. Additional articles were identified through citation tracking. Studies were included if they related to older people, if the intervention aimed to alleviate social isolation and loneliness, if intervention participants were compared against inactive controls and, if treatment effects were reported. Two independent reviewers extracted data using a standardised form. Narrative synthesis and vote-counting methods were used to summarise and interpret study data. RESULTS: Thirty two studies were included in the review. There was evidence of substantial heterogeneity in the interventions delivered and the overall quality of included studies indicated a medium to high risk of bias. Across the three domains of social, mental and physical health, 79% of group-based interventions and 55% of one-to-one interventions reported at least one improved participant outcome. Over 80% of participatory interventions produced beneficial effects across the same domains, compared with 44% of those categorised as non-participatory. of interventions categorised as having a theoretical basis, 87% reported beneficial effects across the three domains compared with 59% of interventions with no evident theoretical foundation. Regarding intervention type, 86% of those providing activities and 80% of those providing support resulted in improved participant outcomes, compared with 60% of home visiting and 25% of internet training interventions. Fifty eight percent of interventions that explicitly targeted socially isolated or lonely older people reported positive outcomes, compared with 80% of studies with no explicit targeting. CONCLUSIONS: More, well-conducted studies of the effectiveness of social interventions for alleviating social isolation are needed to improve the evidence base. However, it appeared that common characteristics of effective interventions were those developed within the context of a theoretical basis, and those offering social activity and/or support within a group format. Interventions in which older people are active participants also appeared more likely to be effective. Future interventions incorporating all of these characteristics may therefore be more successful in targeting social isolation in older people.

BACKGROUND: Previous reviews demonstrate uncertainty about the effectiveness of nurse-led interventions in the management of hypertension. No specific reviews in diabetes have been identified. We have systematically reviewed the evidence for effectiveness of nurse-led interventions for people with diabetes mellitus. METHODS: in this systematic review and meta-analysis, searches of Medline, Embase, CINAHL and the Cochrane Central Trials register were undertaken to identify studies comparing any intervention conducted by nurses in managing hypertension in diabetes with usual doctor-led care. Additional citations were identified from papers retrieved and correspondence with authors. Outcome measures were absolute systolic and diastolic blood pressure, change in blood pressure, proportions achieving study target blood pressure and proportions prescribed anti-hypertensive medication. RESULTS:   Eleven studies were identified. Interventions included adoption of treatment algorithms, nurse-led clinics and nurse prescribing. Meta-analysis showed greater reductions in blood pressure in favour of any nurse-led interventions (systolic weighted mean difference -5.8 mmHg, 95% CI -9.6 to -2.0; diastolic weighted mean difference -4.2 mmHg, 95% CI -7.6 to -0.7) compared with usual doctor-led care. No overall superiority in achievement of study targets or in the use of medication was evident for any nurse-based interventions over doctor-led care. CONCLUSIONS: There is some evidence for improved blood pressure outcomes with nurse-led interventions for hypertension in people with diabetes compared with doctor-led care. Nurse-based interventions require an algorithm to structure care and there is some preliminary evidence for better outcomes with nurse prescribing. Further work is needed to elucidate which nurse-led interventions are most effective.

Background.
Clinical guidance recommends physical activity as a means of managing patients with persistent sub-threshold depressive symptoms or mild to moderate depression. However, little is known regarding the acceptability of physical activity as a treatment for depression from the patients’ perspective.

Aim.
To explore patients’ views of physical activity for the treatment of depression in the context of primary care.

Design.
In-depth interviews were held with 33 participants taking part in a RCT assessing the effectiveness of physical activity for the management of depression.

Setting.
Primary care
Results.
Most participants perceived physical activity to be an acceptable treatment for depression. The mechanisms by which physical activity could enhance mood were attributed to a number of subjective benefits including biochemical pathways, providing a source of distraction from negative thoughts and a sense of purpose. Participants reporting a belief in biochemical mechanisms thought activity that ‘raised the heartbeat’ was most beneficial, while those reporting distraction tended to state the benefits of less aerobic activities such as walking. However, many participants reported low motivation and a lack of confidence as barriers to undertaking physical activity. These patients suggested that medication could be helpful for initiating and maintaining activity.







Conclusion.
Patients’ view physical activity as an effective treatment for depression. However, they vary in their views about how physical activity might impact on depression, what intensity and form of activity is necessary to enhance mood and the barriers to undertaking activity. This variation suggests the need for GPs to elicit patients’ views on physical activity as a treatment and offer interventions that are tailored to the needs and expectations of individual patients.

Objective: to compare the volume and quality of original research in primary care published by researchers from primary care in the United Kingdom against five countries with well established academic primary care. Design: Bibliometric analysis. Setting: United Kingdom, United States, Australia, Canada, Germany, and the Netherlands. Studies reviewed: Research publications relevant to comprehensive primary care and authored by researchers from primary care, recorded in Medline and Embase, with publication dates 2001-7 inclusive. Main outcome measures: Volume of published activity of generalist primary care researchers and the quality of the research output by those publishing the most using citation metrics: numbers of cited papers, proportion of cited papers, and mean citation scores. Results: 82 169 papers published between 2001 and 2007 in the six countries were classified as research on primary care. In a 15% pragmatic random sample of these records, 40% of research on primary care from the United Kingdom and 46% from the Netherlands was authored by researchers employed in a primary care setting or employed in academic departments of primary care. The 141 researchers with the highest volume of publications reporting research findings published between 2001 and 2007 (inclusive) authored or part authored 8.3% of the total sample of papers. For authors with the highest proportion of publications cited at least five times, the best performers came from the United States (n=5), United Kingdom (n=4), and the Netherlands (n=2). In the top 10 of authors with the highest proportions of publications achieving 20 or more citations, six were from the United Kingdom and four from the United States. The mean Hirsch index (measure of a researcher's productivity and impact of the published work) was 14 for the Netherlands, 13 for the United Kingdom, 12 for the United States, 7 for Canada, 4 for Australia, and 3 for Germany. Conclusion: This international comparison of the volume and citation rates of papers by researchers from primary care consistently placed UK researchers among the best performers internationally.

This paper reflects on Eleanor Ostrom's classic book, Governing the Commons, and much work in sociology, political science and organization studies that has appeared since its publication. We do so in order to expand our understanding of the conditions under which cooperation occurs resulting in the production of collective goods. We explore two issues that were underdeveloped in her book that have subsequently received much attention. First, we discuss how states can facilitate cooperative behavior short of coercively imposing it on actors. Second, we discuss how social capital can facilitate or undermine cooperative behavior. In both cases we focus on the important mechanisms by which each one contributes to the development of cooperative behavior and collective goods. We conclude by extending our arguments to a brief analysis of one of the world's newest and largest collective goods-the Internet.

BACKGROUND: Exercise referral schemes (ERS) aim to identify inactive adults in the primary-care setting. The GP or health-care professional then refers the patient to a third-party service, with this service taking responsibility for prescribing and monitoring an exercise programme tailored to the needs of the individual. OBJECTIVE: to assess the clinical effectiveness and cost-effectiveness of ERS for people with a diagnosed medical condition known to benefit from physical activity (PA). The scope of this report was broadened to consider individuals without a diagnosed condition who are sedentary. DATA SOURCES: MEDLINE; EMBASE; PsycINFO; the Cochrane Library, ISI Web of Science; SPORTDiscus and ongoing trial registries were searched (from 1990 to October 2009) and included study references were checked. METHODS: Systematic reviews: the effectiveness of ERS, predictors of ERS uptake and adherence, and the cost-effectiveness of ERS; and the development of a decision-analytic economic model to assess cost-effectiveness of ERS. RESULTS: Seven randomised controlled trials (UK, n = 5; non-UK, n = 2) met the effectiveness inclusion criteria, five comparing ERS with usual care, two compared ERS with an alternative PA intervention, and one to an ERS plus a self-determination theory (SDT) intervention. In intention-to-treat analysis, compared with usual care, there was weak evidence of an increase in the number of ERS participants who achieved a self-reported 90-150 minutes of at least moderate-intensity PA per week at 6-12 months' follow-up [pooled relative risk (RR) 1.11, 95% confidence interval 0.99 to 1.25]. There was no consistent evidence of a difference between ERS and usual care in the duration of moderate/vigorous intensity and total PA or other outcomes, for example physical fitness, serum lipids, health-related quality of life (HRQoL). There was no between-group difference in outcomes between ERS and alternative PA interventions or ERS plus a SDT intervention. None of the included trials separately reported outcomes in individuals with medical diagnoses. Fourteen observational studies and five randomised controlled trials provided a numerical assessment of ERS uptake and adherence (UK, n = 16; non-UK, n = 3). Women and older people were more likely to take up ERS but women, when compared with men, were less likely to adhere. The four previous economic evaluations identified suggest ERS to be a cost-effective intervention. Indicative incremental cost per quality-adjusted life-year (QALY) estimates for ERS for various scenarios were based on a de novo model-based economic evaluation. Compared with usual care, the mean incremental cost for ERS was £169 and the mean incremental QALY was 0.008, with the base-case incremental cost-effectiveness ratio at £20,876 per QALY in sedentary people without a medical condition and a cost per QALY of £14,618 in sedentary obese individuals, £12,834 in sedentary hypertensive patients, and £8414 for sedentary individuals with depression. Estimates of cost-effectiveness were highly sensitive to plausible variations in the RR for change in PA and cost of ERS. LIMITATIONS: We found very limited evidence of the effectiveness of ERS. The estimates of the cost-effectiveness of ERS are based on a simple analytical framework. The economic evaluation reports small differences in costs and effects, and findings highlight the wide range of uncertainty associated with the estimates of effectiveness and the impact of effectiveness on HRQoL. No data were identified as part of the effectiveness review to allow for adjustment of the effect of ERS in different populations. CONCLUSIONS: There remains considerable uncertainty as to the effectiveness of ERS for increasing activity, fitness or health indicators or whether they are an efficient use of resources in sedentary people without a medical diagnosis. We failed to identify any trial-based evidence of the effectiveness of ERS in those with a medical diagnosis. Future work should include randomised controlled trials assessing the cinical effectiveness and cost-effectivenesss of ERS in disease groups that may benefit from PA.

AIM: to systematically review studies reporting the effectiveness of various models of follow-up in primary care on a range of outcomes (physical, psychological, social functioning, or quality of life) for survivors of stroke and their caregivers. BACKGROUND: Stroke is a major cause of disability globally. Current UK policy calls for a primary care-based review of healthcare and social-care needs at six weeks and six months after hospital discharge and then annually. METHODS: Trials meeting the pre-defined inclusion criteria were identified by the systematic searching of electronic databases. Data were extracted by two independent researchers. Studies were rated using the McMaster University Quality Assessment Tool. FINDINGS: Nine randomised controlled trials that met the inclusion criteria were identified. These studies included interventions using stroke support workers, care coordinators or case managers. The methodological quality of the studies was variable, and models of care demonstrated inconsistent working relationships with general practitioners. Patients and caregivers receiving formal primary care-based follow-up did not show any gains in physical function, mood, or quality of life when compared with those who did not. Patients and caregivers receiving follow-up were generally more satisfied with some aspects of communication, and had a greater knowledge of stroke. CONCLUSIONS: the limited quality of these studies and the lack of a sound theoretical basis for the development of interventions together highlight the urgent need for high-quality research studies in this area.

AIM: to explore the experiences of people with advanced cancer and/or their caregivers accessing out-of-hours care. BACKGROUND: the organisation and delivery of out-of-hours in the United Kingdom has undergone major reforms over the past three decades culminating in the new General Medical Service contract in 2004. There are concerns around continuity of care for patients with complex needs under the new arrangements. DESIGN: a qualitative interview study was undertaken recruiting patients from two primary care trusts in Southwest England. Semi-structured interviews were conducted with 28 people with advanced cancer and/or their caregivers who had recently requested out-of-hours care. Interviews were recorded, transcribed and analysed thematically. FINDINGS: Two main themes were identified including the legitimacy of seeking help and continuities of care. Most participants were reluctant to seek help, finding it difficult to decide whether their needs were sufficient to contact services. The degree to which services legitimised participants' requests mediated their experiences. Distress arose when services were dismissive of their needs, whereas respondents were appreciative of clinicians who provided them with reassurance. Participants reported a lack of relational and informational continuity of care. Consulting with an unfamiliar clinician out-of-hours raised doubts in some participants' minds about the quality of care. Some participants recounted episodes in which there were problems with pain management. While the themes suggest that the delivery of out-of-hours care as a whole was not always perfect, around-the-clock access to professional sources of support and reassurance was highly valued. However, the transfer of information to out-of-hours providers remains a key challenge; participants did not understand why out-of-hours providers could not access more information on their medical histories given the level of computerisation within the National Health Service. The findings highlight the need to improve continuity between in-hours and out-of-hours services for patients with complex needs.

PURPOSE: to investigate for socially isolated older people, and older people at risk of social isolation: (1) health status and health-related quality of life (HRQL); (2) the relationship between social isolation and health status/HRQL; (3) the relationship between two alternative measures of health status/HRQL. METHODS: Older people at risk of social isolation (n = 393) completed the EQ-5D and the SF-12. Multiple regression analyses were performed to examine the relationship between levels of social isolation and health status/HRQL, controlling for demographic/clinical characteristics. The agreement between EQ-5D and SF-6D (SF-12) scores was explored using descriptive psychometric techniques. RESULTS: Health status and health state values were much lower than UK general population age-matched norms. After controlling for depression, physical co-morbidities, age, gender, living alone status, employment and accommodation, social isolation was significantly associated, to a degree that was clinically relevant, with EQ-5D DSI, SF-6D (SF-12) and SF-12 MCS scores. The potential for ceiling effects on the EQ-5D with this population was identified. CONCLUSION: This work highlights the burden that social isolation may have on the health and well-being of older people. The potential HRQL gains from addressing social isolation may be considerable, with those at risk of social isolation also a key target group.

BACKGROUND: to explore how chronic musculoskeletal pain is managed in multidisciplinary pain clinics for patients for whom physical interventions are inappropriate or ineffective. METHODS: a qualitative study was undertaken using semi-structured interviews with twenty five members of the pain management team drawn from seven pain clinics and one pain management unit located across the UK. RESULTS: all clinics reported using a multidisciplinary bio-psychosocial model. However the chronic pain management strategy actually focussed on psychological approaches in preference to physical approaches. These approaches were utilised by all practitioners irrespective of their discipline. Consideration of social elements such as access to social support networks to support patients in managing their chronic pain was conspicuously absent from the approaches used. CONCLUSION: Pain clinic practitioners readily embraced cognitive/behavioural based management strategies but relatively little consideration to the impact social factors played in managing chronic pain was reported. Consequently multidisciplinary pain clinics espousing a bio-psychosocial model of pain management may not be achieving their maximum potential.

To determine the preferred means by which participants in a study of cardiac rehabilitation wish to be informed of the study's results. Postal questionnaire survey of participants in a randomized controlled trial. Cornwall, southwest England. Patients recruited to the Cornwall Heart Attack Rehabilitation Management Study (CHARMS). Participants recruited to CHARMS who were alive 3 years and 9 months after the trial was completed were contacted by letter and invited to return a reply slip with four short questions indicating how they would prefer to be informed about the published results of the study. In March 2008, 191/230 participants originally recruited to CHARMS were still alive. General practitioners deemed 166/191 (88%) survivors medically appropriate to be contacted through a postal survey, and 154/166 (93%) participants responded to the invitation to participate in the follow-up survey. 86% (143/166) of participants indicated that they wished to be informed about the results: 115 (80%) of these elected to receive information by letter and 25 (18%) of these preferred to attend a meeting. Men older than 65 years predominated in this latter group. Women respondents preferred to receive the study results by letter; none preferred communication by email or the web. Survivors of acute myocardial infarction who participated in a RCT of cardiac rehabilitation wanted to receive a summary of the aggregate study results. Participants had preferences regarding how they would wish to be informed about the results of the study. Most participants preferred to be informed by letter or email, but some preferred the interaction of a group or a meeting.

Objectives There is growing interest in multi-source, multi-level feedback for measuring the performance of health care professionals. However, data are often unbalanced (e.g. there are different numbers of raters for each doctor), uncrossed (e.g. raters rate the doctor on only one occasion) and fully nested (e.g. raters for a doctor are unique to that doctor). Estimating the true score variance among doctors under these circumstances is proving a challenge. Methods Extensions to reliability and generalisability (G) formulae are introduced to handle unbalanced, uncrossed and fully nested data to produce coefficients that take into account variances among raters, ratees and questionnaire items at different levels of analysis. Decision (D) formulae are developed to handle predictions of minimum numbers of raters for unbalanced studies. An artificial dataset and two real-world datasets consisting of colleague and patient evaluations of doctors are analysed to demonstrate the feasibility and relevance of the formulae. Another independent dataset is used for validating D predictions of G coefficients for varying numbers of raters against actual G coefficients. A combined G coefficient formula is introduced for estimating multi-sourced reliability. Results the results from the formulae indicate that it is possible to estimate reliability and generalisability in unbalanced, fully nested and uncrossed studies, and to identify extraneous variance that can be removed to estimate true score variance among doctors. The validation results show that it is possible to predict the minimum numbers of raters even if the study is unbalanced. Discussion Calculating G and D coefficients for psychometric data based on feedback on doctor performance is possible even when the data are unbalanced, uncrossed and fully nested, provided that: (i) variances are separated at the rater and ratee levels, and (ii) the average number of raters per ratee is used in calculations for deriving these coefficients. © 2010 Blackwell Publishing Ltd.

Clinicians claim that myofascial trigger points (MTrPs) are a primary cause of pain in whiplash injured patients. Pain from MTrPs is often treated by needling, with or without injection. We conducted a placebo controlled study to test the feasibility of a phase III randomised controlled trial investigating the efficacy of MTrP needling in patients with whiplash associated pain. Forty-one patients referred for physiotherapy with a recent whiplash injury, were recruited. Patients were randomised to receive standardised physiotherapy plus either acupuncture or a sham needle control. A trial was judged feasible if: i) the majority of eligible patients were willing to participate; ii) the majority of patients had MTrPs; iii) at least 75% of patients provided completed self-assessment data; iv) no serious adverse events were reported and v) the end of treatment attrition rate was less than 20%. 70% of those patients eligible to participate volunteered to do so; all participants had clinically identified MTrPs; a 100% completion rate was achieved for recorded self-assessment data; no serious adverse events were reported as a result of either intervention; and the end of treatment attrition rate was 17%. A phase III study is both feasible and clinically relevant. This study is currently being planned.

Objective: to review trials of nurse led interventions for hypertension in primary care to clarify the evidence base, establish whether nurse prescribing is an important intervention, and identify areas requiring further study. Design: Systematic review and meta-analysis. Data sources: Ovid Medline, Cochrane Central Register of Controlled Trials, British Nursing Index, Cinahl, Embase, Database of Abstracts of Reviews of Effects, and the NHS Economic Evaluation Database. Study selection: Randomised controlled trials of nursing interventions for hypertension compared with usual care in adults. Data extraction: Systolic and diastolic blood pressure, percentages reaching target blood pressure, and percentages taking antihypertensive drugs. Intervention effects were calculated as relative risks or weighted mean differences, as appropriate, and sensitivity analysis by study quality was undertaken. Data synthesis: Compared with usual care, interventions that included a stepped treatment algorithm showed greater reductions in systolic blood pressure (weighted mean difference -8.2 mm Hg, 95% confidence interval -11.5 to -4.9), nurse prescribing showed greater reductions in blood pressure (systolic -8.9 mm Hg, -12.5 to -5.3 and diastolic -4.0 mm Hg, -5.3 to -2.7), telephone monitoring showed higher achievement of blood pressure targets (relative risk 1.24, 95% confidence interval 1.08 to 1.43), and community monitoring showed greater reductions in blood pressure (weighted mean difference, systolic -4.8 mm Hg, 95% confidence interval -7.0 to -2.7 and diastolic -3.5 mm Hg, -4.5 to -2.5). Conclusions: Nurse led interventions for hypertension require an algorithm to structure care. Evidence was found of improved outcomes with nurse prescribers from non-UK healthcare settings. Good quality evidence from UK primary health care is insufficient to support widespread employment of nurses in the management of hypertension within such healthcare systems.

Background: Depression is one of the most common reasons for consulting a General Practitioner (GP) within the UK. Whilst antidepressants have been shown to be clinically effective, many patients and healthcare professionals
would like to access other forms of treatment as an alternative or adjunct to drug therapy for depression. A recent
systematic review presented some evidence that physical activity could offer one such option, although further
investigation is needed to test its effectiveness within the context of the National Health Service.
The aim of this paper is to describe the protocol for a randomised, controlled trial (RCT) designed to evaluate an
intervention developed to increase physical activity as a treatment for depression within primary care.
Methods/design: the TREAD study is a pragmatic, multi-centre, two-arm RCT which targets patients presenting
with a new episode of depression. Patients were approached if they were aged 18-69, had recently consulted their
GP for depression and, where appropriate, had been taking antidepressants for less than one month. Only those
patients with a confirmed diagnosis of a depressive episode as assessed by the Clinical Interview Schedule-Revised
(CIS-R), a Beck Depression Inventory (BDI) score of at least 14 and informed written consent were included in the
study. Eligible patients were individually randomised to one of two treatment groups; usual GP care or usual GP
care plus facilitated physical activity. The primary outcome of the trial is clinical symptoms of depression assessed
using the BDI four months after randomisation. A number of secondary outcomes are also measured at the 4-, 8-
and 12-month follow-up points including quality of life, attitude to and involvement in physical activity and
antidepressant use/adherence. Outcomes will be analysed on an intention-to-treat (ITT) basis and will use linear
and logistic regression models to compare treatments.
Discussion: the results of the trial will provide information about the effectiveness of physical activity as a
treatment for depression. Given the current prevalence of depression and its associated economic burden, it is
hoped that TREAD will provide a timely contribution to the evidence on treatment options for patients, clinicians
and policy-makers.

AIM: to determine the feasibility of recruiting patients with early chronic obstructive pulmonary disease (COPD) to the Health Enhancing Activity in Lung THerapy (HEALTH) exercise and education programme. METHODS: Patients with early COPD were identified from general practices. Those meeting the study inclusion criteria were administered tiotropium throughout the study period. Participants were randomised to either an eight-week health enhancing and physical activity (HEPA) programme, or to a control group (usual care). Behavioural, physiological and psychosocial outcome measures were reported preand post-intervention. RESULTS: Out of 27 practices approached, 16 (59.3%) agreed to participate. of 215 potentially eligible patients contacted, 60 (27.9%) replied. Twenty (33.3%) were randomised to either HEPA intervention (n=10) or usual care (n=10). Fourteen patients attended a postintervention assessment. CONCLUSION: This study provides valuable information on the feasibility of conducting such a trial involving a physical activity intervention.

Feedback from colleagues and patients is a core element of the revalidation process being developed by the General Medical Council. However, there are few feedback tools which have been specifically developed and validated for doctors in primary care. This paper presents data demonstrating the reliability and validity of one such tool. The CFEP360 tool combines feedback from the Colleague Feedback Evaluation Tool (CFET) and the Doctor's Interpersonal Skills Questionnaire (DISQ). The analysis of over 10 000 completed questionnaires presented here identifies that colleague feedback is essentially two-dimensional (i.e. clinical and non-clinical skills) and that patient feedback is one-dimensional. However, items from both scales also effectively predict combined global ratings, indicating that colleagues and patients are identifying similar levels of performance as accessed by the feedback. Doctors who receive low feedback scores may require further attention, meaning the feedback potentially has diagnostic value. Reliable feedback on this tool, as indicated by this analysis, requires 14 colleague responses and 25 patient responses, figures comparable to other MSF tools if CFEP360 is to be used for a high stakes performance evaluation and possible revalidation (generalisability statistic G> or =0.80). For lower stakes performance evaluations, such as personal development, responses from 11 colleagues and 16 patients will still return reliable results (G> or =0.70).

CONTEXT: Colleague surveys are important sources of information on a doctor's professional performance in UK revalidation plans. Colleague surveys are analysed by deriving quantitative measures from rating scales. As free-text comments are also recorded, we explored the utility of a mixed-methods approach to their analysis. METHODS: a volunteer sample of practising UK doctors (from acute, primary and other care settings) undertook a General Medical Council (GMC) colleague survey. Up to 20 colleagues per doctor completed an online Colleague Questionnaire (CQ), which included 18 performance evaluation items and an optional comment box. The polarity of each comment was noted and a qualitative content analysis undertaken. Emerging themes were mapped onto existing items to identify areas not previously captured. We then quantitatively analysed the associations between the polarity of comments (positive/adverse) and their related item scale scores. RESULTS: a total of 1636 of 4269 (38.3%) colleagues recorded free-text comments (median = 14 per doctor) and most were unequivocally positive; only 127 of 1636 (7.8%) recorded negative statements and these were clustered on a subset comprising 80 of 302 (26.5%) doctors. Doctors' overall mean CQ performance scores were significantly correlated with the numbers of colleagues recording positive (r = 0.35; P < 0.0001) and adverse (r = - 0.40; P = 0.0003) comments. In total, 1224 of 1636 (74.8%) comments included statements that mapped on CQ items, and statistically significant associations (P < 0.05) were observed for 14 of 15 items. Five global themes (innovativeness, interpersonal skills, popularity, professionalism, respect) were identified in 904 of 1636 (73.9%) comments. CONCLUSIONS: There is an inevitable trade-off between the capturing of indicators of problematic performance (i.e. adverse statements which contradict a positive scale rating) and the ease with which such statements can be identified. Our data suggest there is little benefit in routinely analysing narrative comments for the purposes of revalidation.

Pain from myofascial trigger points is often treated by needling, with or without injection, although evidence is inconclusive on whether this is effective. We aimed to review the current evidence on needling without injection, by conducting a systematic literature review. We searched electronic databases to identify relevant randomised controlled trials, and included studies where at least one group were treated by needling directly into the myofascial trigger points, and where the control was either no treatment, or usual care; indirect local dry needling or some form of placebo intervention. We extracted data on pain, using VAS scores as the standard. Seven studies were included. One study concluded that direct dry needling was superior to no intervention. Two studies, comparing direct dry needling to needling elsewhere in the muscle, produced contradictory results. Four studies used a placebo control and were included in a meta-analysis. Combining these studies (n=134), needling was not found to be significantly superior to placebo (standardised mean difference, 14.9 [95%CI, -5.81 to 33.99]), however marked statistical heterogeneity was present (I(2)=88%). In conclusion, there is limited evidence deriving from one study that deep needling directly into myofascial trigger points has an overall treatment effect when compared with standardised care. Whilst the result of the meta-analysis of needling compared with placebo controls does not attain statistically significant, the overall direction could be compatible with a treatment effect of dry needling on myofascial trigger point pain. However, the limited sample size and poor quality of these studies highlights and supports the need for large scale, good quality placebo controlled trials in this area.

OBJECTIVES: to develop a sham needle device and test its credibility as a control for acupuncture when used in a randomised controlled trial of myofascial trigger point needling in patients with whiplash associated pain. METHODS: sham needles were developed by blunting true acupuncture needles. Whiplash injured patients (

BACKGROUND: Headache is the most frequent neurological symptom and the most common manifestation of pain in childhood. Estimates of the prevalence of headache in children and adolescents vary widely (depending on the setting, methodology, and diagnostic criteria applied) and the impact is not well understood. AIM: to quantify the impact of headache in a school population. DESIGN OF STUDY: a questionnaire survey. SETTING: Exeter schools. METHOD: a total of 1037 school children between the ages of 12 and 15 years were surveyed, of whom 49% were female. Main outcome measures were headache frequency, disease-specific impact using the Pediatric Migraine Disability Assessment Score (PedMIDAS), and generic quality of life impact using the Pediatric Quality of Life Inventory (PedsQL4). RESULTS: Twenty per cent of the study population had headache one or more times a week, with an average PedMIDAS score of over 12.1 (and an impact on over 12 days in a 3-month period). Ten per cent of the population had a PedMIDAS score of 16.8 and a PedsQL4 generic quality of life score of 70.1, indicating a poorer quality of life than that of children with asthma, diabetes, or cancer. An average of 0.6 days of school was lost in a 3-month period across all school children. CONCLUSION: There is a significant impact of headache on the quality of life of children. This impact is both unrecognised and unmet. GPs have an important role in identification and management of this problem.

BACKGROUND: Previous studies have identified a substantial prevalence of a blood pressure difference between arms in various populations, but not patients with type 2 diabetes. Recognition of such a difference would be important as a potential cause of underestimation of blood pressure. AIM: to measure prevalence of an inter-arm blood pressure difference in patients with type 2 diabetes, and to estimate how frequently blood pressure measurements could be erroneously underestimated if an inter-arm difference is unrecognised. DESIGN OF STUDY: Cross-sectional study. SETTING: Five surgeries covered by three general practices, Devon, England. METHOD: Patients with type 2 diabetes underwent bilateral simultaneous blood pressure measurements using a validated protocol. Mean blood pressures were calculated for each arm to derive mean systolic and diastolic differences, and to estimate point prevalence of predefined magnitudes of difference. RESULTS: a total of 101 participants were recruited. Mean age was 66 years (standard deviation [SD] = 13.9 years); 59% were male, and mean blood pressure was 138/79 mmHg (SD = 15/10 mmHg). Ten participants (10%; 95% confidence interval [CI] = 4 to 16) had a systolic inter-arm difference > or =10 mmHg; 29 (29%; 95% CI = 20 to 38) had a diastolic difference >/=5 mmHg; and three (3%; 95% CI = 0 to 6) a diastolic difference > or =10 mmHg. No confounding variable was observed to account for the magnitude of an inter-arm difference. CONCLUSION: a systolic inter-arm difference > or =10 mmHg was observed in 10% of patients with diabetes. Failure to recognise this would misclassify half of these as normotensive rather than hypertensive using the lower-reading arm. New patients with type 2 diabetes should be screened for an inter-arm blood pressure difference.

Headache is the most frequent neurological symptom and commonest manifestation of pain in childhood. Measuring the impact of headache in terms of health status, functioning and quality of life can inform the prioritization of competing resource claims, screen for unmet need, improve communication between patient and physician and monitor response to treatment. We undertook a critical review of the literature measuring the impact of headache in children and identified 33 papers that contained relevant information. Findings reflected a wide range of settings, age groups, methodologies and outcome measures. Considerable methodological limitations affected all studies, including inadequate description of study design, methodology and data analysis. Nevertheless, although we found the existing literature to be of inconsistent quality, the impact of headache in children and adolescents is substantial. Rigorous studies are required to quantify this burden using measures that are valid and reliable and whose development has been informed by both theoretical and practical perspectives.

Objective: to assess the robustness of patient responses to a new national survey of patient experience as a basis for providing financial incentives to doctors. Design: Analysis of the representativeness of the respondents to the GP Patient Survey compared with those who were sampled (5.5 million patients registered with 8273 general practices in England in January 2009) and with the general population. Analysis of non-response bias looked at the relation between practice response rates and scores on the survey. Analysis of the reliability of the survey estimated the proportion of the variance of practice scores attributable to true differences between practices. Results: the overall response rate was 38.2% (2.2 million responses), which is comparable to that in surveys using similar methodology in the UK. Men, young adults, and people living in deprived areas were under-represented among respondents. However, for questions related to pay for performance, there was no systematic association between response rates and questionnaire scores. Two questions which triggered payments to general practitioners were reliable measures of practice performance, with average practice-level reliability coefficients of 93.2% and 95.0%. Less than 3% and 0.5% of practices had fewer than the number of responses required to achieve conventional reliability levels of 90% and 70%. A change to the payment formula in 2009 resulted in an increase in the average impact of random variation in patient scores on payments to general practitioners compared with payments made in 2007 and 2008. Conclusions: There is little evidence to support the concern of some general practitioners that low response rates and selective non-response bias have led to systematic unfairness in payments attached to questionnaire scores. The study raises issues relating to the validity and reliability of payments based on patient surveys and provides lessons for the UK and for other countries considering the use of patient experience as part of pay for performance schemes.

To gain insight into factors affecting patient and practitioner satisfaction with access to healthcare in a remote rural island community. General practice based primary care is the focus of health service delivery in rural areas of the UK. Individuals from rural populations have reported inequalities in access to healthcare. User satisfaction with service performance is recognised as an important outcome of healthcare. Further investigation into factors underpinning patient and practitioner satisfaction with access to rural healthcare is required. Qualitative interviews with patients and primary healthcare practitioners. Isles of Scilly, Cornwall, UK. A topic guide was developed following review of the literature. In-depth, semi-structured interviews with a purposive sample of 23 participants were conducted with individuals from all inhabited islands. Detailed field notes were kept, and interview content was partially transcribed and analysed thematically. Principal themes identified were common to patient and practitioner participants. These were: concerns expressed regarding the equitable provision of services; obstacles to using health services; and the outlook of patients and professionals, including expectations, choice, patient–practitioner relationships and community cohesiveness. Emerging themes gave insight into a range of factors affecting satisfaction with access to healthcare. Despite numerous policy initiatives aimed at reducing inequities in health service provision, problems with access and uptake of health services persist amongst individuals from remote rural populations. If implemented, recent National Health Service proposals may address some of the challenges identified by participants. Service developments need to take account of local priorities, expectations, geography and demography to achieve favourable outcomes. © 2009, Cambridge University Press. All rights reserved.

BACKGROUND: the UK National GP Patient Survey is one of the largest ever survey programmes of patients registered to receive primary health care, inviting five million respondents to report their experience of NHS primary healthcare. The third such annual survey (2008/9) involved the development of a new survey instrument. We describe the process of that development, and the findings of an extensive pilot survey in UK primary healthcare. METHODS: the survey was developed following recognised guidelines and involved expert and stakeholder advice, cognitive testing of early versions of the survey instrument, and piloting of the questionnaire in a cross sectional pilot survey of 1,500 randomly selected individuals from the UK electoral register with two reminders to non-respondents. RESULTS: the questionnaire comprises 66 items addressing a range of aspects of UK primary healthcare. A response rate of 590/1500 (39.3%) was obtained. Non response to individual items ranged from 0.8% to 15.3% (median 5.2%). Participants did not always follow internal branching instructions in the questionnaire although electronic controls allow for correction of this problem in analysis. There was marked skew in the distribution of responses to a number of items indicating an overall favourable impression of care. Principal components analysis of 23 items offering evaluation of various aspects of primary care identified three components (relating to doctor or nurse care, or addressing access to care) accounting for 68.3% of the variance in the sample. CONCLUSION: the GP Patient Survey has been carefully developed and pilot-tested. Survey findings, aggregated at practice level, will be used to inform the distribution of pound sterling 65 million ($107 million) of UK NHS resource in 2008/9 and this offers the opportunity for NHS service planners and providers to take account of users' experiences of health care in planning and delivering primary healthcare in the UK.

PURPOSE: Posttraumatic stress disorder (PTSD) is a common serious condition, which, although treatable, is often undetected. We investigated the prevalence of PTSD in patients with chronic obstructive pulmonary disease (COPD) referred to pulmonary rehabilitation and the impact of rehabilitation on PTSD symptoms. METHODS: Patients with COPD attending pulmonary rehabilitation programs in South West England completed cross-sectional and longitudinal surveys. Outcome measures included the Posttraumatic Diagnostic Scale, Impact of Events scale, Incremental Shuttle Walking Test, Medical Outcomes Short Form 12, Hospital Anxiety and Depression scale (HADS), and Chronic Respiratory Questionnaire. Questionnaires were completed at face-to-face interviews with participants 1 week before commencing pulmonary rehabilitation and at the end of the program. RESULTS: Patients (N = 100), mean age 68 years, 65% men, served as subjects. Seventy-four participants reported traumatic experiences (37 related to lung disease) and 70 completed the pulmonary rehabilitation program. Eight of 100 participants met diagnostic criteria for PTSD. Participants with PTSD reported worse health status than those without PTSD. After pulmonary rehabilitation, exercise capacity and quality of life scores improved significantly, but PTSD symptom severity did not change. CONCLUSIONS: PTSD was present in 8% of COPD patients referred for pulmonary rehabilitation. After rehabilitation, participants with PTSD improved more in respect to anxiety and disease-specific health status than those without PTSD. PTSD symptoms did not improve following rehabilitation, despite its positive effects on HADS scores, exercise, and health status in this cohort.

BACKGROUND: National standards for delivery of out-of-hours services have been refined. Health service users' preferences, reports, and evaluations of care are of importance in a service that aims to be responsive to their needs. AIM: to investigate NHS service users' reports and evaluations of out-of-hours care in the light of UK national service quality requirements. DESIGN: Cross sectional survey. SETTING: Three areas (Devon, Cornwall, Sheffield) of England, UK. METHOD: Participants were 1249 recent users of UK out-of-hours medical services. Main outcome measures were: users' reports and evaluations of out-of-hours services in respect of the time waiting for their telephone call to the service to be answered; the length of time from the end of the initial call to the start of definitive clinical assessment ('call back time'); the time waiting for a home visit; and the waiting time at a treatment centre. RESULTS: UK national quality requirements were reported as being met by two-thirds of responders. Even when responders reported that they had received the most rapid response option for home visiting (waiting time of 'up to an hour'), only one-third of users reported this as 'excellent'. Adverse evaluations of care were consistently related to delays encountered in receiving care and (for two out of four measures) sex of patient. For 50% of users to evaluate their care as 'excellent', this would require calls to be answered within 30 seconds, call-back within 20 minutes, time spent waiting for home visits of significantly less than 1 hour, and treatment centre waiting times of less than 20 minutes. CONCLUSION: Users have high expectations of UK out-of-hours healthcare services. Service provision that meets nationally designated targets is currently judged as being of 'good' quality by service users. Attaining 'excellent' levels of service provision would prove challenging, and potentially costly. Delivering services that result in high levels of user satisfaction with care needs to take account of users' expectations as well as their experience of care.

The aim was to describe the consulting behaviour and clinical outcomes of children presenting with headache in primary care. This was a historical cohort study using data from the UK General Practitioner Research Database. Cases were children aged 5-17 years who presented to primary care with primary headache (migraine, tension-type headache, cluster headache) or undifferentiated headache (no further descriptor). Controls were age, sex and practice matched. Their records were examined for consultations, referrals, relevant treatments and specific diseases in the subsequent year. Children with headache (n = 48 575) were identified and matched to controls. At presentation, 9321 (19.2%) of headaches were labelled primary, 549 (1.1%) secondary and 38 705 (79.7%) received no formal diagnosis. of the latter group, 2084 (5.4%) received a primary headache diagnosis in the subsequent year. Following a diagnosis of migraine, 258 (3.5%) had received a triptan and 1598 (21%) were using propranolol or pizotifen. Total consultations were higher in cases than in controls in the year before the headache: cases ages 5-8 years, mean (s.d.) 5.0 (4.0) consultations; controls 4.0 (3.5) consultations. In 1 year controls had 43 430 consultations, of which 256 (0.6%) were for headache, of whom 64 (25%) were referred to secondary care. Headache was a risk factor for benign and malignant tumours, cerebrovascular disease, primary disorders of raised intracranial pressure and depression. This risk was reduced if a diagnosis of a primary headache disorder could be made. Although there is an increased likelihood of a serious pathology with headache presentations, the risk is small particularly if a diagnosis of a primary headache is made. General practitioners are likely to be underdiagnosing migraine. This study can inform management guidelines for new presentations of headache in primary care, particularly when a secondary pathology is suspected.

BACKGROUND: There is widespread concern that the quality of out-of-hours primary care for patients with complex needs may be at risk now that the new general medical services contract (GMS) has been implemented. AIM: to explore changes in the use of out-of-hours services around the time of implementation of the new contract for patients with complex needs, using patients with cancer as an example. DESIGN OF STUDY: Longitudinal observational study. SETTING: Out-of-hours primary care provider covering Devon (adult population 900,000), UK. METHOD: Two, 1-year periods corresponding to pre- (April 2003 to March 2004) and post-contract implementation (October 2004 to September 2005) were sampled. Call rates per 1000 of the adult population (age>or=16 years) were calculated for all calls (any cause) and cancer-related calls. Anonymised outcome and process measures data were extracted. RESULTS: Although overall call rates per 1000 population had increased by 26% (185 pre-contract to 233 post-contract), the proportion of cancer-related calls remained relatively constant (2.08% versus 1.96%). Around half (56%) of these callers had advanced cancer needs (including palliative care). By post-contract, the time taken to triage had significantly increased (P

OBJECTIVE: to investigate the utility of the GMC patient and colleague questionnaires in assessing the professional performance of a large sample of UK doctors. DESIGN: Cross-sectional questionnaire surveys. SETTING: Range of UK clinical practice settings. PARTICIPANTS: 541 doctors gave preliminary agreement to take part in the study. Responses were received from 13 754 patients attending one of 380 participant doctors, and from 4269 colleagues of 309 participant doctors. MAIN OUTCOME MEASURES: Questionnaire performance and standardised scores for each doctor derived from patient and colleague responses. RESULTS: Participant doctors were similar to non-participants in respect of age and gender. The patient and colleague questionnaires were acceptable to participants as evidenced by low levels of missing data. One patient questionnaire item seemed to cause confusion for respondents and requires rewording. Both patient and colleague responses were highly skewed towards favourable impressions of doctor performance, with high internal consistency. To achieve acceptable levels of reliability, a minimum of 8 colleague questionnaires and 22 patient questionnaires are required. G coefficients for both questionnaires were comparable with internationally recognised survey instruments of broadly similar intent. Patient and colleague assessments provided complementary perspectives of doctors' performance. Older doctors had lower patient-derived and colleague-derived scores than younger doctors. Doctors from a mental health trust and doctors providing care in a variety of non-NHS settings had lower patient scores compared with doctors providing care in acute or primary care trust settings. CONCLUSIONS: the GMC patient and colleague questionnaires offer a reliable basis for the assessment of professionalism among UK doctors. If used in the revalidation of doctors' registration, they would be capable of discriminating a range of professional performance among doctors, and potentially identifying a minority whose practice should to subjected to further scrutiny.

BACKGROUND: Non-pharmacological interventions for chronic knee pain are increasingly requested by patients and are recommended in current treatment guidelines. An intervention that has been used for many years for pain relief is nettle sting. OBJECTIVES: to explore the feasibility of a definitive RCT of nettle sting for chronic knee pain, in particular the acceptability of the research to GPs and patients, and the optimal methods for recruitment and outcome measurement. METHODS: Patient blinded pilot RCT, set in two inner city primary care practices in Plymouth, UK. Potential participants were identified from practice computerised databases using three different approaches: age and analgesic use, age and appropriate Read code, or age alone. Patients had to be aged between 55 and 80 years with knee pain and a presumptive clinical diagnosis of OA knee, with a baseline WOMAC pain subscale score of more than 4. They were randomised to receive either treatment with Urtica dioica, or placebo intervention with Urtica galeopsifolia daily for 1 week. The main outcome measure for the treatment effect was the WOMAC pain subscale; other outcomes included quantitative and qualitative data to inform the design of a future study. RESULTS: Out of 45 patients who were eligible, 42 were recruited. Invitations targeted at patients who were both currently receiving repeat prescriptions for non-steroidal or analgesic drugs and had relevant Read codes proved most efficient for recruitment. Mean baseline WOMAC pain subscale scores were 9.2 (S.D. 3.4) and 7.9 (2.3) in the two groups. The mean reduction in pain score at the end of treatment in the nettles group was 1.7 (95% confidence interval 0.6, 2.9) and in the controls 1.6 (CI 0.5, 2.7). All GP practices, and all patients approached, were willing to be involved in the research. Patients liked the treatment mostly because it was 'natural'. The sting was acceptable and viewed as a minor irritation. CONCLUSION: Research into nettle sting is acceptable to patients and GPs, and patients do not find the treatment more than a minor irritation. Larger rigorous studies are justified to determine the effectiveness of this ancient therapy.

Background. Patients who have had one stroke are at increased risk of another. Secondary prevention strategies that address medical risk factors and promote healthy lifestyles can reduce the risk. However, concordance with secondary prevention strategies is poor and there has been little research into patient and carer views.Objectives. To explore the experiences of patients and carers of receiving secondary prevention advice and use these to inform the development of an educational resource.Methods. A total of 38 participants (25 patients and 13 carers) took part in the study which used an action research approach. Focus groups and interviews were undertaken with patients and carers who had been discharged from hospital after stroke (between 3 and 24 months previously). Framework analysis was used to examine the data and elicit action points to develop an educational resource.Results. Participants' main concern was their desire for early access to information. They commented on their priorities for what information or support they needed, the difficulty of absorbing complex information whilst still an in-patient and how health professionals' use of language was often a barrier to understanding. They discussed the facilitators and barriers to making lifestyle changes. The educational resource was developed to include specific advice for medical and lifestyle risk factors and an individual action plan.Conclusion. An educational resource for secondary prevention of stroke was developed using a participatory methodology. Our findings suggest that this resource is best delivered in a one-to-one manner, but further work is needed to identify its potential utility.

Parkinson's disease (PD) is a neurodegenerative disorder affecting the physical, psychological, social, and functional status of individuals. Exercise programs may be an effective strategy to delay or reverse functional decline for people with PD and a large body of empirical evidence has emerged in recent years. The objective is to systematically review randomized controlled trials (RCTs) reporting on the effectiveness of exercise interventions on outcomes (physical, psychological or social functioning, or quality of life) for people with PD. RCTs meeting the inclusion criteria were identified by systematic searching of electronic databases. Key data were extracted by two independent researchers. A mixed methods approach was undertaken using narrative, vote counting, and random effects meta-analysis methods. Fourteen RCTs were included and the methodological quality of most studies was moderate. Evidence supported exercise as being beneficial with regards to physical functioning, health-related quality of life, strength, balance and gait speed for people with PD. There was insufficient evidence support or refute the value of exercise in reducing falls or depression. This review found evidence of the potential benefits of exercise for people with PD, although further good quality research is needed. Questions remain around the optimal content of exercise interventions (dosing, component exercises) at different stages of the disease.

AIM: to investigate patients' perspectives of sleep in COPD. METHOD: Patients with moderate to severe COPD underwent semi-structured interviews about their sleep experiences. Contextual questionnaire data were collected. RESULTS: Ten patients were studied. Six reported bad sleep, but all described some sleep problems. Nocturnal anxiety and fears of breathlessness and dying were common features; these impacted on existing sleep problems related to exacerbations, medications, and habitual behaviours that can disrupt sleep. Poor sleep was associated with poorer health status. Patients reported a lack of support from their GPs and few had received advice for sleep problems. CONCLUSION: Anxiety about breathlessness affects the sleep experience of patients with COPD, and sleep quality impacts on physical and emotional functioning. Education about behaviours that can disrupt sleep offers potential benefits to the patient. COPD patients' sleep issues are complex and should be addressed at the clinical consultation.

Reported prevalence of myocardial infarction-related post-traumatic stress disorder (PTSD) varies from 0 to 25%. PTSD after myocardial Infarction may affect quality of life, cardiovascular outcomes, and health service usage. of 164 patients with previous myocardial infarction, 111 participated in the study and 36 had PTSD, giving a prevalence of 32%; the lowest possible estimate being 22%. PTSD was associated with significantly worse general health than that of individuals without PTSD. Prevalence of PTSD did not vary with time since myocardial infarction. PTSD was not associated with adverse risk factors for future myocardial infarction, such as smoking, high blood pressure, and poor compliance with medication. PTSD after myocardial infarction may be a common, persistent and overlooked cause of psychological morbidity. © British Journal of General Practice 2007.

BACKGROUND: Tobacco smoking is a serious risk to health: several therapies are available to assist those who wish to stop. Smokers who approach publicly funded stop-smoking clinics in the UK are currently offered nicotine replacement therapy (NRT) or bupropion, and group behaviour therapy, for which there is evidence of effectiveness. Acupuncture and acupressure are also used to help smokers, though a systematic review of the evidence of their effectiveness was inconclusive. The aim of this pilot project was to determine the feasibility of a study to test acupressure as an adjunct to one anti-smoking treatment currently offered, and to inform the design of the study. METHODS: an open randomised controlled pilot study was conducted within the six week group programme offered by the Smoking Advice Service in Plymouth, UK. All participants received the usual treatment with NRT and group behavioural therapy, and were randomised into three groups: group a with two auricular acupressure beads, group B with one bead, and group C with no additional therapy. Participants were taught to press the beads when they experienced cravings. Beads were worn in one ear for four weeks, being replaced as necessary. The main outcome measures assessed in the pilot were success at quitting (expired CO < or = 9 ppm), the dose of NRT used, and the rating of withdrawal symptoms using the Mood and Symptoms Scale. RESULTS: from 49 smokers attending four clinics, 24 volunteered to participate, 19 attended at least once after quitting, and seven remained to the final week. Participants who dropped out reported significantly fewer previous quit attempts, but no other significant differences. Participants reported stimulating the beads as expected during the initial days after quitting, but most soon reduced the frequency of stimulation. The discomfort caused by the beads was minor, and there were no significant side effects. There were technical problems with adhesiveness of the dressing. Reporting of NRT consumption was poor, with much missing data, but reporting of ratings of withdrawal symptom scores was nearly complete. However, these showed no significant changes or differences between groups for any week. CONCLUSION: Any effects of acupressure on smoking withdrawal, as an adjunct to the use of NRT and behavioural intervention, are unlikely to be detectable by the methods used here and further preliminary studies are required before the hypothesis can be tested.

AIMS: to develop and pilot a survey instrument assessing general practitioners' (GP) attitudes to the diagnosis and management of one form of pre-diabetes, impaired glucose tolerance (IGT) and to assess the performance of the questionnaire. METHODS: Qualitative data together with an audit were used to generate questionnaire items, which were then subjected to a process of pre-piloting and piloting to generate a finalised item list. The pilot questionnaire was sent to 222 principal GPs in three PCTs in South West England. The first fifty responders were asked to complete the questionnaire again 2 weeks later. Principal components analysis with a Varimax rotation was used to detect latent factors within the data that may help to explain the attitudes of GPs. RESULTS: the response rate after one reminder was 54.1%. Four robust factors were identified which were internally consistent (range of Cronbach's alpha=0.79-0.65), homogeneous (item-total correlations=0.60-0.21), and stable (test-retest correlation=0.74-0.58) accounting for 31.1% of the variance. The predictive validity of the item list was assessed (P=0.02 for factor 1). CONCLUSIONS: the PAtH questionnaire identifies four factors that help to describe GPs attitudes to the diagnosis and management of IGT.

Background and objective: Provision of out- of- hours care in the UK National Health Service ( NHS) has changed in recent years with new models of provision and the introduction of national quality requirements. Existing survey instruments tend to focus on users' satisfaction with service provision; most were developed without undertaking supporting qualitative fieldwork. In this study, a survey instrument was developed taking account of these changes in service provision and undertaking supporting qualitative fieldwork. This paper reports on the development and psychometric properties of the new survey instrument, the Out- of- hours Patient Questionnaire ( OPQ), which aims to capture information on the entirety of users' experiences of out-of-hours care, from the decision to make contact through to completion of their care management. Methods: an iterative approach was undertaken to develop the new instrument which was then tested in users of out- of- hours services in three geographically distributed UK settings. For the purposes of this study, " service users'' were defined as `` individuals about whom contact was made with an out- of- hours primary care medical service'', whether that contact was made by the user themselves, or via a third party. Analysis was undertaken of the acceptability, reliability and validity of the survey instrument. Results: the OPQ tested is a 56- item questionnaire, which was distributed to 1250 service users. Respondents were similar in respect of gender, but were older and more affluent ( using a proxy measure) than non-respondents. Item completion rates were acceptable. Respondents sometimes completed sections of the questionnaire which did not equate to their principal mode of management as recorded in the record of the contact. Preliminary evidence suggests the OPQ is a valid and reliable instrument which contains within it two discrete scales - a consultation satisfaction scale ( nine items) and an `` entry- access'' scale ( four items). Further work is required to determine the generalisability of findings obtained following use of the OPQ, especially to non- white user populations. Conclusion: the OPQ is an acceptable instrument for capturing information on users' experiences of out- ofhours care. Preliminary evidence suggests it is both valid and reliable in use. Further work will report on its utility in informing out- of- hours service planning and configuration and standard- setting in relation to UK national quality requirements.

AIMS: to identify key messages about pre-diabetes and to design, develop and pilot an educational toolkit to address the information needs of patients and health professionals. METHODS: Mixed qualitative methodology within an action research framework. Focus group interviews with patients and health professionals and discussion with an expert reference group aimed to identify the important messages and produce a draft toolkit. Two action research cycles were then conducted in two general practices, during which the draft toolkit was used and video-taped consultations and follow-up patient interviews provided further data. Framework analysis techniques were used to examine the data and to elicit action points for improving the toolkit. RESULTS: the key messages about pre-diabetes concerned the seriousness of the condition, the preventability of progression to diabetes, and the need for lifestyle change. As well as feedback on the acceptability and use of the toolkit, four main themes were identified in the data: knowledge and education needs (of both patients and health professionals); communicating knowledge and motivating change; redesign of practice systems to support pre-diabetes management and the role of the health professional. The toolkit we developed was found to be an acceptable and useful resource for both patients and health practitioners. CONCLUSIONS: Three key messages about pre-diabetes were identified. A toolkit of information materials for patients with pre-diabetes and the health professionals and ideas for improving practice systems for managing pre-diabetes were developed and successfully piloted. Further work is needed to establish the best mode of delivery of the WAKEUP toolkit.

Provision of welfare benefits advice to maximise financial benefit uptake is a shared goal for social and health policy in the UK. The study was designed to explore the wider impact on elderly people provided with specialist welfare benefits advice, in terms of their health and quality of life. This paper reports on a longitudinal postal survey of community dwellers aged 60 and over referred for specialist welfare benefits advice within social services and who were followed up at 5 months (over 2003-2004). Outcome measures included the Short Form-36 (SF-36), the General Health Questionnaire-12 (GHQ-12) and the Barthel Index (postal version), along with questions relating to chronic illness. We also report on the methodological issues that arise from conducting research of this nature. Out of 233 elderly people sent questionnaires, 77 (33%) returned a completed baseline questionnaire. of the 156 who did not return questionnaires, 35 (22%) gave reasons of being 'too unwell' to participate. Between baseline and follow-up, 8 (10%) of the 77 respondents died; 52 of the 69 (75%) remaining participants completed follow-up questionnaires. Although low, these response rates are comparable with other similar questionnaire surveys examining the outcome of providing benefits advice to individuals. Elderly people (mean age = 80.3, SD = 8.6 years) receiving welfare benefits advice usually reported the presence of a longstanding illness or disability, and the use of healthcare services. Baseline SF-36 scores were extremely low and remained largely unchanged at follow-up; however, there were significant improvements in GHQ-12 scores (mean difference = -1.45, 95% CI = -2.63 to -0.27, P = 0.017). Significant increases in benefit income were identified in 65% of respondents with complete financial data sets (mean increase = pound14.73 per week; 95% CI = 5.27-24.18, d.f. = 39, P = 0.003). Participants were very vulnerable in their health status (compared with normative data for elderly people), and this may have contributed to the difficulty in engaging them in the research. There are methodological issues around establishing cause and effect in this type of study, which cannot be readily designed out on account of ethical issues. Extraction and analysis of financial status and benefit eligibility with a view to determining absolute changes in the material well-being of vulnerable individuals over time is a complex and challenging task. Use of suitable measures is essential. Innovative strategies are necessary to maximise survey response rates amongst the vulnerable elderly population.

BACKGROUND: Since 2000, out-of-hours primary medical care services in the UK have undergone major changes in the organisation and delivery of services in response to recommendations by the Carson Review and more recently, through the new General Medical Services Contract (GMS2). People calling their general practice in the evening or at weekends are redirected to the out-of-hours service which may offer telephone advice, a home visit or a visit to a treatment centre. Little is known about users' experiences under the new arrangements. AIM: to explore users' experiences of out-of-hours primary medical care. DESIGN OF STUDY: a qualitative study employing focus groups and telephone interviews. SETTING: Three out-of-hours primary medical care service providers in England. METHODS: Focus groups and telephone interviews were conducted with 27 recent users of out-of-hours services. RESULTS: Key areas of concern included the urgency with which cases are handled, and delays when waiting for a call back or home visit. Users felt that providers were reluctant to do home visits. The service was regarded as under-resourced and frequently misused. Many expressed anxiety about calling, feeling unsure about how appropriate their call was and many were uncertain about how the service operated. CONCLUSIONS: Service users need clear information on how current out-of-hours services operate and how it should be used. Problems with triaging need to be addressed, users should be kept informed of any delays, and care needs to be taken to ensure that the new arrangements do not alienate older people or individuals with complex health needs.

BACKGROUND: Home-based cardiac rehabilitation offers an alternative to traditional, hospital-based cardiac rehabilitation. AIM: to compare the cost effectiveness of home-based cardiac rehabilitation and hospital-based cardiac rehabilitation. METHODS: 104 patients with an uncomplicated acute myocardial infarction and without major comorbidity were randomized to receive home-based rehabilitation (n=60) i.e. nurse facilitated, self-help package of 6 weeks' duration (the Heart Manual) or hospital-based rehabilitation for 8-10 weeks (n=44). Complete economic data were available in 80 patients (48 who received home-based rehabilitation and 32 who received hospital-based rehabilitation). Healthcare costs, patient costs, and quality of life (EQ-5D4.13) were assessed over the 9 months of the study. RESULTS: the cost of running the home-based rehabilitation programme was slightly lower than that of the hospital-based programme (mean (95% confidence interval) difference - 30 pounds sterling (- 45 pounds sterling to - 12 pounds sterling) [-44 euro, -67 euro to -18 euro] per patient. The cost difference was largely the result of reduced personnel costs. Over the 9 months of the study, no significant difference was seen between the two groups in overall healthcare costs (78 pounds sterling, - 1102 pounds sterling to 1191 pounds sterling [-115 euro, -1631 euro to -1763 euro] per patient) or quality adjusted life-years (-0.06 (-0.15 to 0.02)). The lack of significant difference between home-based rehabilitation and hospital-based rehabilitation did not alter when different costs and different methods of analysis were used. CONCLUSIONS: the health gain and total healthcare costs of the present hospital-based and home-based cardiac rehabilitation programmes for patients after myocardial infarction appear to be similar. These initial results require affirmation by further economic evaluations of cardiac rehabilitation in different settings.

BACKGROUND: Participation in cardiac rehabilitation after acute myocardial infarction is sub-optimal. Offering home-based rehabilitation may improve uptake. We report the first randomized study of cardiac rehabilitation to include patient preference. AIM: to compare the clinical effectiveness of a home-based rehabilitation with hospital-based rehabilitation after myocardial infarction and to determine whether patient choice affects clinical outcomes. DESIGN: Pragmatic randomized controlled trial with patient preference arms. SETTING: Rural South West England. METHODS: Patients admitted with uncomplicated myocardial infarction were offered hospital-based rehabilitation classes over 8-10 weeks or a self-help package of six weeks' duration (the Heart Manual) supported by a nurse. Primary outcomes at 9 months were mean depression and anxiety scores on the Hospital Anxiety Depression scale, quality of life after myocardial infarction (MacNew) score and serum total cholesterol. RESULTS: of the 230 patients who agreed to participate, 104 (45%) consented to randomization and 126 (55%) chose their rehabilitation programme. Nine month follow-up data were available for 84/104 (81%) randomized and 100/126 (79%) preference patients. At follow-up no difference was seen in the change in mean depression scores between the randomized home and hospital-based groups (mean difference: 0; 95% confidence interval, -1.12 to 1.12) nor mean anxiety score (-0.07; -1.42 to 1.28), mean global MacNew score (0.14; -0.35 to 0.62) and mean total cholesterol levels (-0.18; -0.62 to 0.27). Neither were there any significant differences in outcomes between the preference groups. CONCLUSIONS: Home-based cardiac rehabilitation with the Heart Manual was as effective as hospital-based rehabilitation for patients after myocardial infarction. Choosing a rehabilitation programme did not significantly affect clinical outcomes.

BACKGROUND: Patients with asthma are particularly susceptible to serious complications from influenza. The Chief Medical Officer recommends annual influenza vaccination for adult patients with asthma. The uptake of influenza vaccination by patients with asthma is only 40% and, unlike other high-risk groups, has failed to increase in recent years. AIM: to investigate the contribution of sociodemographic factors, asthma morbidity, and health beliefs to influenza vaccination uptake in patients with asthma. DESIGN OF STUDY: Cross-sectional questionnaire study. SETTING: Single urban British general practice, Exeter, UK. METHOD: a questionnaire survey was sent to adult patients with asthma. Participants were aged 16-65 years, were receiving beta(2) agonists and inhaled steroids, and had been invited for influenza vaccination in September 2003. Data were examined using univariate analysis and logistic regression. RESULTS: a total of 136/204 (66.7%) patients responded to the survey. Influenza vaccination uptake in the study population was 40%. Younger patients were less likely to have undergone vaccination than older patients. There was no difference in vaccination uptake rates between groups of patients defined by other sociodemographic factors. Asthma morbidity was similar in vaccinated and non-vaccinated groups of patients. Vaccinated individuals had a greater belief in the efficacy of the vaccination and medical advice regarding the vaccination, and felt more susceptible to influenza and its complications when compared with non-vaccinated individuals. A fear of side-effects was associated with declining the invitation for vaccination. These health beliefs were the only independent predictors of uptake of influenza vaccination among this group of patients with asthma. CONCLUSION: Improving vaccination uptake in patients with asthma is unlikely unless individual health beliefs are taken into account.

BACKGROUND: UK and US policy initiatives have suggested that, in the future, patients and clinicians in mainstream medicine could use genetic information to prevent common illnesses. There are no studies on patients' experience and understanding of the process of testing for common genetic susceptibilities in mainstream medicine. METHODS: Qualitative interviews with 42 individuals who had undergone testing for a genetic susceptibility for deep vein thrombosis in primary and secondary care in the UK. RESULTS: Some participants, often from higher social classes, had a good understanding of the test and its implications. They had often sought additional information on thrombophilia from relatives and from the Internet. Others, often from less privileged backgrounds, had a poorer understanding of the test--seven individuals were unaware of having had the genetic test. Features of genetic information led to misunderstandings: (i) at referral, (ii) when communicating results, and (iii) when making sense of the implications of testing. Participants' accounts indicated that non-specialist doctors may feel obliged to refer a patient for a genetic test they know little about, because a patient requests it after a relative had tested positive. Sometimes a referral for a genetic test was lost under information overload when multiple tests and issues were considered. The inconsistent and informal ways of communicating test results--for example by phone--in mainstream medicine also led to confusion. Participants did not generally overestimate their risk, but some were uncertain about whether they were taking the right preventive actions and/or whether their children were at risk. Information about genetic susceptibilities was difficult to make sense of, as it related to ambiguous risks for participants and family members, complicated and unfamiliar terminology and multiple genes and preventive strategies. CONCLUSION: Policy visions of clinicians and patients in mainstream medicine seeking and using genetic information at their own initiative may not be realistic. Patients need more direct support in making sense of genetic information, if this information is to bring the anticipated health benefits, and not fuel health inequalities or create ethical problems. Clinicians in secondary and primary care need guidance to help them introduce genetic tests, communicate their results and explain their implications.

There is both a clear need and a political will to improve self-care in long-term conditions: demand for self-care support interventions is rising. This article discusses current approaches to supporting self-care in primary care, evidence in favour of self-care support, and issues for GPs to consider in planning self-care support systems. In planning care pathways, important choices need to be made about whether to use individual or group-based approaches and what intensity of intervention is appropriate to match patient needs. Investment may also be needed in both health professional competences and practice systems to optimise their ability to support patient self-care. Self-care support is a key approach for the future of UK health care. Practices that are well trained and well organised to support self-care will respond better to the complex challenges of achieving improvements in the outcomes of long-term conditions.

BACKGROUND: a blood pressure (BP) difference between the upper limbs is often encountered in primary care. Knowledge of its prevalence and importance in the accurate measurement of BP is poor, representing a source of error. Current hypertension guidelines do not emphasize this. OBJECTIVES: to establish the prevalence of an inter-arm blood pressure difference (IAD) and explore its association with other indicators of peripheral vascular disease (PVD) in a hypertensive primary care population. METHODS: This was a cross-sectional study. Primary care, one rural general practice, was the setting of the study. The methods were controlled simultaneous measurement of brachial BPs, ankle-brachial pressure index (ABPI) and tiptoe stress testing in 94 subjects. RESULTS: in all, 18 of 94 [19%, 95% confidence interval (CI) 11-27%] subjects had mean systolic inter-arm difference (sIAD) > or =10 mmHg and seven of 94 (7%, 95% CI 2-12%) had mean diastolic inter-arm difference (dIAD) > or =10 mmHg. Nineteen of 91 (20%, 95% CI 12-28%) had a reduced ABPI. or =20%. CONCLUSIONS: an IAD and asymptomatic PVD are common in a primary care hypertensive population. Magnitude of the IAD is inversely correlated with ABPI, supporting the hypotheses that IADs are causally linked to PVD, and that IAD is a useful marker for the presence of PVD. Consequently, detection of an IAD should prompt the clinician to screen subjects for other signs of vascular disease and target them for aggressive cardiovascular risk factor modification.

Objectives of this study were to measure the prevalence of a difference in blood pressure (BP) between arms and determine whether a difference is associated with increased risk of cardiovascular events or death. A prospective cohort study of 247 patients with hypertension was undertaken in one rural general practice in England. The main outcome measures were mean difference in BP between arms and new episodes of myocardial infarction, cerebrovascular event, onset of angina or peripheral vascular disease or death. A total of 57/247 (23%) patients had a mean difference in systolic BP between arms of >or=10 mm Hg and 8/247 (3%) had a mean difference of >or=20 mm Hg. A total of 15/247 (6%) patients had a mean difference in diastolic BP between arms of >or=10 mm Hg. Survival analysis after 4.7 years (range 3.3-5.9) showed a shorter mean survival time without event or death for patients with a difference in systolic BP of >or=10 mm Hg compared with a difference of

OBJECTIVES: the aim of the literature review was to investigate the criteria adopted by "experts" to diagnose myofascial trigger point (MTrP) pain syndrome. Experts were defined as being either researchers investigating MTrP pain syndrome or the "authority" the researchers cited as a source of reference for MTrP pain syndrome diagnosis. METHODS: We searched electronic databases to identify relevant empirical research (excluding studies not in English and those relating to dental pathology). of 607 possibly relevant publications 93 met our inclusion criteria. We recorded (1) the individual criterion and criteria combinations used to diagnose MTrP pain syndrome; (2) the cited "authoritative" publications and (3) the criteria recommended by the authoritative publications as being essential for MTrP pain syndrome diagnosis. RESULTS: the review identified 19 different diagnostic criteria. The 4 most commonly applied criteria were: "tender spot in a taut band" of skeletal muscle, "patient pain recognition," "predicted pain referral pattern," and "local twitch response." There was no consistent pattern to the choice of specific diagnostic criteria or their combinations. However, one pair of criteria "tender point in a taut band" and "predicted or recognized pain referral" were used by over half the studies. The great majority of studies cited publications by Travell and more recently Simons as a principal authoritative source for MTrP pain syndrome diagnosis, yet most of these studies failed to apply the diagnostic criteria as described by these authorities. DISCUSSION: We conclude that there is as yet limited consensus on case definition in respect of MTrP pain syndrome. Further research is needed to test the reliability and validity of diagnostic criteria. Until reliable diagnostic criteria have been established, there is a need for greater transparency in research papers on how a case of MTrP pain syndrome is defined, and claims for effective interventions in treating the condition should be viewed with caution.

Background: Acupuncture and related techniques are promoted as a treatment for smoking cessation in the belief that they may reduce nicotine withdrawal symptoms. Objectives: the objectives of this review are to determine the effectiveness of acupuncture and the related interventions of acupressure, laser therapy and electrostimulation, in smoking cessation in comparison with no intervention, sham treatment, or other interventions. Search strategy: We searched the Cochrane Tobacco Addiction Group specialized register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, BIOSIS Previews, PsycINFO, Science and Social Sciences Citation Index, AMED and CISCOM. Date of last search January 2005. Selection criteria: Randomized trials comparing a form of acupuncture, acupressure, laser therapy or electrostimulation with either no intervention, sham treatment or another intervention for smoking cessation. Data collection and analysis: We extracted data in duplicate on the type of smokers recruited, the nature of the acupuncture and control procedures, the outcome measures, method of randomization, and completeness of follow up. We assessed abstinence fromsmoking at the earliest time-point (before six weeks), and at the lastmeasurement point between sixmonths and one year. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. Those lost to follow up were counted as continuing smokers. Where appropriate, we performed meta-analysis using a fixed-effect model. Main results: We identified 24 reports of studies. The only comparison for which there were sufficient studies to combine meaningfully was acupuncture compared with sham acupuncture. The fixed-effect odds ratio (OR) for the short-term effect was 1.36 (95% confidence interval 1.07 to 1.72), but the studies are heterogeneous and the result is strongly influenced by one individual positive study. The significant short-term effect was lost with the random-effects model for pooling, or by removing the outlying study that led to heterogeneity. The long-term result shows no effect of acupuncture compared with sham acupuncture. There was no consistent evidence that acupuncture is superior to no treatment, and no evidence that the effect of acupuncture was different from that of other anti-smoking interventions, or that any particular acupuncture technique is superior to other techniques. Authors' conclusions: There is no consistent evidence that acupuncture, acupressure, laser therapy or electrostimulation are effective for smoking cessation, but methodological problems mean that no firm conclusions can be drawn. Further research using frequent or continuous stimulation is justified. Copyright © 2006 the Cochrane Collaboration. Published by John Wiley & Sons, Ltd.

A blood pressure (BP) difference between arms was first reported over 100 years ago. Knowledge of its prevalence and relevance to the accurate measurement of BP remains poor. Current hypertension guidelines do not emphasise it. The objectives of this study were to establish the best estimate of prevalence of the inter-arm difference (IAD) in the population, to consider its implications for accurate BP measurement and treatment, and to discuss its aetiology and potential as a risk marker for cardiovascular disease. Systematic literature review was carried out. The data sources were Medline EMBASE and CINAHL databases, and Index of Theses. Studies reporting prevalence rates of IAD were retrieved and considered for inclusion against explicit methodological criteria. Point prevalence rates were extracted and weighted mean prevalence rates calculated. The main outcome measures were weighted mean prevalences of systolic IAD > or =10 and > or =20 mm Hg and of diastolic IAD > or =10 mm Hg. Thirty-one studies were identified. Most had methodological weaknesses; only four met the inclusion criteria. Pooled prevalences of the IAD from these four studies were 19.6% systolic > or =10 mm Hg (95% CI 18.0-21.3%), 4.2% systolic > or =20 mm Hg (95% CI 3.4-5.1%) and 8.1% diastolic > or =10 mm Hg (95%CI 6.9-9.2%). In conclusion, an IAD is present in a substantial number of patients and should be looked for whenever diagnosis and treatment depend on accurate measurements of BP. The importance of an IAD should be better emphasised in current hypertension management guidelines. There is evidence associating an IAD with peripheral vascular disease, raising the possibility that its presence may predict cardiovascular events.

BACKGROUND: the government has proposed a 48-hour target for GP availability. Although many practices are moving towards delivering that goal, recent national patient surveys have reported a deterioration in patients' reports of doctor availability. What practice factors contribute to patients' perceptions of doctor availability? METHOD: a cross sectional patient survey (11,000 patients from 54 inner London practices, 7247 (66%) respondents) using the General Practice Assessment Survey. We asked patients how soon they could be seen in their practice following non-urgent consultation requests and related their aggregated responses to the characteristics of their practice. RESULTS: Three factors relating to practice administration and appointments systems operation independently predicted patients' reports of doctor availability. These were the proportion of patients asked to attend the surgery and wait to be seen, the proportion of patients seen using an emergency surgery arrangement, and the extent of practice computerization. CONCLUSION: Some practices may have difficulty in meeting the target for GP availability. Meeting the target will involve careful review of practice administrative procedures.

AIM: to determine if medical practitioners with congenital colour vision deficiencies (CCVD) are less able to identify and delineate the extent of coloured abnormal signs than those with normal colour vision. METHOD: Twenty-two medical practitioners with CCVD and 17 with normal colour vision, matched for age and gender, were shown 10 photographs. They were asked to identify and outline the extent of the clinical sign in eight that were of vomit or stool (six of these showing fresh blood), one of a skin rash and for one to mark the position of bacilli in sputum stained by the Ziehl-Neelsen method. RESULTS: There were statistically significant differences between the CCVD practitioners and those with normal colour vision in their ability to outline abnormalities in five of the six photographs that showed fresh blood, in the photograph of a rash and in marking the position of bacilli in the photograph of a stained slide. CONCLUSION: Medical practitioners with CCVD are handicapped in their evaluation of the presence and extent of coloured clinical signs. Medical schools should ensure that students with CCVD are aware of their deficiency and know its severity, so they can take special care in clinical practice.

Purpose: the goal of this study was to describe bathing, toileting, and mouth care habits and preferences of older persons, as well as the importance of such habits. Design and Methods: Fifty-eight community-dwelling older persons were administered the Self-maintenance Habits and Preferences in Elderly questionnaire (SHAPE) during a one-on-one interview with a research assistant. Preferences were described by frequency distributions and mean importance for each item was calculated. Gender differences in preferences were examined using χ2 analyses, t tests were used to compare importance levels. Results: Women reported spending a longer time bathing, they were more likely to have privacy while bathing, to use a washcloth, a regular size towel, and less likely to use a large towel than were men. One-third of the women reported using some type of absorbent undergarment, while no men did so. Mouth care was the category that received the highest importance ratings. Although order of importance of items was similar across genders, women assigned higher levels of importance to these items than did men. Importance ratings given to atypical habits, such as unusually long or more than 1 bath/day, were higher than those attributed to more usual habits. Implications: Knowledge of the range and importance of such self-care practices can provide information useful in the development of programs and for individualized care. Copyright © 2005 S.

BACKGROUND: in 2003, the National Health Service in England and Wales, despite its large investment in information and communication technology, had not set a national research agenda. The National Health Service has three main research and development programs: one is the Service Delivery and Organisation program, commissioned in 2003, and the others are two parallel "scoping exercises" to help set a research agenda. This paper reports on one of those projects. A parallel literature review was carried out by others and has been reported elsewhere. OBJECTIVE: the objective was to explore the concerns of stakeholders and to review relevant policy in order to produce recommendations and a conceptual map of eHealth research. METHODS: There were two parallel strands. For the stakeholder consultation, 37 professionals representing 12 "stakeholder" groups participated in focus groups or interviews. Discussion was prompted by eHealth "scenarios" and analyzed using thematic content analysis. Subsequently, 17 lay participants, in three focus groups, discussed and prioritized these themes. For the policy review, 26 policy makers were interviewed, and 95 policy documents were reviewed. Recommendations were subsequently reviewed in a conference workshop. Recommendations for research from both strands were combined into a conceptual map. RESULTS: Themes from stakeholder consultation and policy review were combined as 43 recommendations under six headings. Four of these headings (using, processing, sharing, and controlling information) describe the scope of eHealth research. The other two relate to how research should be carried out (ensuring best practice is first identified and disseminated) and to the values considered important by stakeholders (in particular, measuring improvement in health). CONCLUSIONS: the scope of eHealth research (using, processing, sharing, controlling information) derived empirically from this study corresponds with "textbook" descriptions of informatics. Stakeholders would like eHealth research to include outcomes such as improved health or quality of life, but such research may be long term while changes in information technology are rapid. Longer-term research questions need to be concerned with human behavior and our use of information, rather than particular technologies. In some cases, "modelling" longer-term costs and benefits (in terms of health) may be desirable.

Previous research has suggested that progress towards suicide reduction targets may be achieved by improving the ability of general practitioners to recognise and treat mental illness. Using data from a study of suicide completers who were not in contact with specialist mental health services, we found that the rate of detection and treatment of mental health problems in primary care was high. The major barrier to receipt of care for mental health problems prior to suicide was non-consultation. The study also shows that detection and management in primary care does not necessarily result in prevention of suicide. Implications for public education, access to primary care services and the potential for suicide prevention are considered.

Primary care has a key role in improving the health of patients who have had a myocardial infarction

BACKGROUND: Physicians with congenital colour vision deficiency (CCVD) have reported difficulties recognising certain physical signs of illness, for example, jaundice, red rashes and pallor, and interpreting coloured charts, diagrams and slide projections. However, there has been little study of the effects of CCVD on the performance of medical practitioners. AIM: the aim of this study was to look for evidence of the effect of CCVD on the ability of physicians to recognise and describe physical signs of illness that have colour as either the main or an important feature. METHOD: Twenty-three general practitioners with CCVD were shown 11 colour photographs depicting colour signs of illness and were asked to describe the signs they saw and rate their confidence in making their descriptions. Their responses were compared to those of 23 age-matched general practitioners with normal colour vision. RESULT: General practitioners with CCVD compared to those with normal colour vision had less ability and confidence in detecting physical signs in the photographs and naming the colours. CONCLUSIONS: the results of this study support other evidence that physicians with CCVD have difficulties detecting some colour signs of illness and naming the colours. Because of the use of photographs the extent of the problem in clinical practice is unknown but medical practitioners with CCVD should be aware of the possibility of failing to detect or correctly assess physical signs that are characterised by colour.

For the management of a condition such as asthma, patients should feel confident with their medication, feel that the treatment is adequate in controlling symptoms and that side-effects of the treatment are minimal. As no comprehensive instrument to measure patient satisfaction with inhaled asthma medication existed, the Satisfaction with Asthma Treatment Questionnaire was developed. The procedures that were used are described, and the initial validation and reliability tests are reported. The study involved focus group meetings, development, testing and modification of a preliminary instrument, and testing of the revised instrument using different samples of patients with asthma. Factor analysis of the 26-item questionnaire identified four domains reflecting four aspects of satisfaction: effectiveness of treatment, ease of use, medication burden, and side-effects and worries. Cronbach's alpha showed evidence of internal consistency reliability. Test/retest reliability ranged from 0.66-0.74. Interscale correlations were moderate-to-high. Significant correlations were found between domain and overall scale scores and patients' overall level of satisfaction. The Satisfaction with Asthma Treatment Questionnaire is potentially a useful instrument for gaining insight into patient satisfaction with inhaled treatment for asthma.

Objectives: to examine patients' views on access and continuity in general practice to derive quality standards. Design: Secondary analysis of data from general practice research studies and routine quality assessment activities undertaken by practices and primary care trusts. Setting: General practice. Participants: General practice patients. Results: Satisfactory standards of access were next day appointments with general practitioners and a 6-10 minute wait for consultations to begin. A satisfactory level of continuity was seeing the same general practitioner "a lot of the time." Standards varied with the analytic method used and by sociodemographic group. Conclusions: Standards expected by patients in primary care can be derived from linked report-assessment pairs. Patients may have expectations of access that are in excess of government targets. Patients also have high expectations of continuity of care. It is unclear the degree to which such standards are reliable or valid, how conflicts between access and continuity should be resolved, or how these standards relate to other priorities of patients such as high quality interpersonal care.

Primary care in the NHS changed substantially during the 1990s. In recent years, structural changes, most notably the introduction of primary care groups as an administrative centre for planning, have added impetus to the need for adopting meaningful measures of quality of the primary care service. This qualitative study reports the views of a sample of general practitioners, primary care nurses, and practice managers on the development and refinement of current performance indicators. Seven themes were identified as key areas for development of indicators of performance: patient experience, clinical activity, service development and innovation, access, health promotion, cost effectiveness, and quality of life outcomes. These themes are incorporated into a dynamic framework for development where improved outcomes (including quality of life measures) are seen as central to the evaluation of quality, and inter-professional collaboration in the delivery and evaluation of quality of the new primary care is called for. © MCB University Press.
