Introduction Although the new generation of cardiac
troponin assays have revolutionised the diagnosis of
myocardial infarction (MI), their application in triaging
patients with suspected acute coronary syndrome
requires further investigation. The objectives of the current
systematic review are to evaluate the diagnostic accuracy
of contemporary and high-sensitivity cardiac troponin
assays used in serial testing, versus single-sample testing
as a comparator, to identify patients with non-ST-segmentelevation
MI in the emergency department.
Methods and analysis We will conduct systematic
searches of MEDLINE, EMBASE, Science Citation Index,
the Cochrane Database of Systematic Reviews and the
CENTRAL database covering the period from 1 January 2006
to present, with no restrictions on language or publication
status. Two review authors will independently screen studies
for inclusion, extract data from eligible studies and assess
their methodological quality using Quality Assessment
of Diagnostic Accuracy Studies version 2. Studies will be
included if they evaluate contemporary or high-sensitivity
cardiac troponin assays used in serial testing, in patients
presenting to the ED with suspicion of MI. Estimates of
sensitivity and specificity from each study will be presented
in forest plots and in the receiver-operating characteristics
space. If appropriate, we will pool the results using Bayesian
hierarchical models that allow correction for imperfect
reference standard. We will obtain summary estimates of
sensitivity and specificity of alternative testing protocols and
compare their accuracy. We will also investigate the impact
of prespecified sources of heterogeneity and methodological
quality items. If pooling of results is considered inappropriate,
we will present our findings in tables and diagrams and will
describe them narratively.
Ethics and dissemination No formal ethical approval will
be sought, but we will report on the ethical approval of the
included studies. Dissemination of findings will be through
publications in peer-reviewed journals, presentations at
conferences and the websites of the universities.

Inequalities within academia – and the research outputs of academic – are a widely acknowledged problem. This results in the reproduction of knowledge gaps within academic praxis. The current study presents a case study from an environment and human health research group, looking at the extent to which the research outputs mirror the wider knowledge gaps in the field. We use systematic review search methods to obtain publications for an environment and health research group since 2010. We use a combination of EndNote and VosViewer to analyse the frequency of key words and concepts in the titles, abstracts and keywords of these publications. We retrieved a total of 950 publications between 2010 and 2022. We find significant gaps with respect to key concepts appearing in the titles, abstracts and keywords of publications. We find that terms such as ‘colonisation’ and ‘racism’ are not mentioned at all. We reflect on the production process of academic research with respect to reproducing blind spots within environment and human health research. We discuss our results in the context of calls to make academic research more inclusive.

OBJECTIVES: to systematically review the accuracy of artificial intelligence (AI)-based systems for grading of fundus images in diabetic retinopathy (DR) screening. METHODS: We searched MEDLINE, EMBASE, the Cochrane Library and the ClinicalTrials.gov from 1st January 2000 to 27th August 2021. Accuracy studies published in English were included if they met the pre-specified inclusion criteria. Selection of studies for inclusion, data extraction and quality assessment were conducted by one author with a second reviewer independently screening and checking 20% of titles. Results were analysed narratively. RESULTS: Forty-three studies evaluating 15 deep learning (DL) and 4 machine learning (ML) systems were included. Nine systems were evaluated in a single study each. Most studies were judged to be at high or unclear risk of bias in at least one QUADAS-2 domain. Sensitivity for referable DR and higher grades was ≥85% while specificity varied and was

OBJECTIVE: the academic and scientific community has reacted at pace to gather evidence to help and inform about COVID-19. Concerns have been raised about the quality of this evidence. The aim of this review was to map the nature, scope and quality of evidence syntheses on COVID-19 and to explore the relationship between review quality and the extent of researcher, policy and media interest. DESIGN AND SETTING: a meta-research: systematic review of reviews. INFORMATION SOURCES: PubMed, Epistemonikos COVID-19 evidence, the Cochrane Library of Systematic Reviews, the Cochrane COVID-19 Study Register, EMBASE, CINAHL, Web of Science Core Collection and the WHO COVID-19 database, searched between 10 June 2020 and 15 June 2020. ELIGIBILITY CRITERIA: Any peer-reviewed article reported as a systematic review, rapid review, overview, meta-analysis or qualitative evidence synthesis in the title or abstract addressing a research question relating to COVID-19. Articles described as meta-analyses but not undertaken as part of a systematic or rapid review were excluded. STUDY SELECTION AND DATA EXTRACTION: Abstract and full text screening were undertaken by two independent reviewers. Descriptive information on review type, purpose, population, size, citation and attention metrics were extracted along with whether the review met the definition of a systematic review according to six key methodological criteria. For those meeting all criteria, additional data on methods and publication metrics were extracted. RISK OF BIAS: for articles meeting all six criteria required to meet the definition of a systematic review, AMSTAR-2 ((A MeaSurement Tool to Assess systematic Reviews, version 2.0) was used to assess the quality of the reported methods. RESULTS: 2334 articles were screened, resulting in 280 reviews being included: 232 systematic reviews, 46 rapid reviews and 2 overviews. Less than half reported undertaking critical appraisal and a third had no reproducible search strategy. There was considerable overlap in topics, with discordant findings. Eighty-eight of the 280 reviews met all six systematic review criteria. of these, just 3 were rated as of moderate or high quality on AMSTAR-2, with the majority having critical flaws: only a third reported registering a protocol, and less than one in five searched named COVID-19 databases. Review conduct and publication were rapid, with 52 of the 88 systematic reviews reported as being conducted within 3 weeks, and a half published within 3 weeks of submission. Researcher and media interest, as measured by altmetrics and citations, was high, and was not correlated with quality. DISCUSSION: This meta-research of early published COVID-19 evidence syntheses found low-quality reviews being published at pace, often with short publication turnarounds. Despite being of low quality and many lacking robust methods, the reviews received substantial attention across both academic and public platforms, and the attention was not related to the quality of review methods. INTERPRETATION: Flaws in systematic review methods limit the validity of a review and the generalisability of its findings. Yet, by being reported as 'systematic reviews', many readers may well regard them as high-quality evidence, irrespective of the actual methods undertaken. The challenge especially in times such as this pandemic is to provide indications of trustworthiness in evidence that is available in 'real time'. PROSPERO REGISTRATION NUMBER: CRD42020188822.

INTRODUCTION: Uncertainty is an inevitable part of medical practice. An ability to tolerate uncertainty is viewed as a key competency across many health-care systems. Poor uncertainty tolerance (UT) has been linked to negative outcomes including reduced psychological well-being in medical students. A variety of medical education interventions have been developed with the intention of increasing medical students' UT. However, there is no synthesis of these studies available to inform education and research practice. Our aim was to conduct a scoping review of medical education interventions that evaluate their impact on UT. METHODS: Medline, PsycInfo, Embase and ERIC databases were searched for articles published from inception to December 2020. An extensive supplementary search was conducted and both quantitative and qualitative evaluations were included. For each intervention, we categorised the stimulus of uncertainty (ambiguity, complexity and/or probability) and mapped the students' reported cognitive, behavioural, and/or emotional response(s) to uncertainty onto an existing conceptual framework. RESULTS: Twenty-two of 24 included studies reported a positive impact on medical student UT in at least one domain (cognitive, behavioural or emotional). Interventions included problem based learning-based curricula, medical humanities, simulation, reflection and assessment. We found in four studies that a negative response in the emotional domain was reported despite positive responses also being reported in the cognitive and/or behavioural domains. CONCLUSION: We identified a range of medical education interventions which report a positive impact on medical student UT. Further research is required to understand why a single intervention may stimulate a negative emotional response alongside a positive cognitive or behavioural response. In turn, this could support stakeholders such as policymakers and institutions to adapt the medical curriculum to better prepare their medical students for practice by enhancing their UT.

Abstract
. Approximately two-thirds of hospital admissions are older adults and almost half of these are likely to have some form of dementia. People with dementia are not only at an increased risk of adverse outcomes once admitted, but the unfamiliar environment and routinised practices of the wards and acute care can be particularly challenging for them, heightening their confusion, agitation and distress further impacting the ability to optimise their care. It is well established that a person-centred care approach helps alleviate some of the unfamiliar stress but how to embed this in the acute-care setting remains a challenge. In this article, we highlight the challenges that have been recognised in this area and put forward a set of evidence-based ‘pointers for service change’ to help organisations in the delivery of person-centred care. The DEMENTIA CARE pointers cover areas of: dementia awareness and understanding, education and training, modelling of person-centred care by clinical leaders, adapting the environment, teamwork (not being alone), taking the time to ‘get to know’, information sharing, access to necessary resources, communication, involving family (ask family), raising the profile of dementia care, and engaging volunteers. The pointers extend previous guidance, by recognising the importance of ward cultures that prioritise dementia care and institutional support that actively seeks to raise the profile of dementia care. The pointers provide a range of simple to more complex actions or areas for hospitals to help implement person-centred care approaches; however, embedding them within the organisational cultures of hospitals is the next challenge.

ObjectivesWe aimed to assess the diversity and practices of existing studies on several assays and algorithms for serial measurements of high-sensitivity cardiac troponin (hs-cTn) for risk stratification and the diagnosis of myocardial infarction (MI) and 30-day outcomes in patients suspected of having non-ST-segment elevation MI (NSTEMI).MethodsWe searched multiple databases including MEDLINE, EMBASE, Science Citation Index, the Cochrane Database of Systematic Reviews and the CENTRAL databases for studies published between January 2006 and November 2021. Studies that assessed the diagnostic accuracy of serial hs-cTn testing in patients suspected of having NSTEMI in the emergency department (ED) were eligible. Data were analysed using the scoping review method.ResultsWe included 86 publications, mainly from research centres in Europe, North America and Australasia. Two hs-cTn assays, manufactured by Abbott (43/86) and Roche (53/86), dominated the evaluations. The studies most commonly measured the concentrations of hs-cTn at two time points, at presentation and a few hours thereafter, to assess the two-strata or three-strata algorithm for diagnosing or ruling out MI. Although data from 83 studies (97%) were prospectively collected, 0%–90% of the eligible patients were excluded from the analysis due to missing blood samples or the lack of a final diagnosis in 53 studies (62%) that reported relevant data. Only 19 studies (22%) reported on head-to-head comparisons of alternative assays.ConclusionEvidence on the accuracy of serial hs-cTn testing was largely derived from selected research institutions and relied on two specific assays. The proportions of the eligible patients excluded from the study raise concerns about directly applying the study findings to clinical practice in frontline EDs.PROSPERO registration numberCRD42018106379.

AbstractBackgroundA challenge when using Google Search to identify studies for a systematic review is managing the high number of results, which can number in the hundreds of thousands or even more. Studies and guidance on web searching suggest limiting the screening process, e.g. to the first 100 results.ObjectivesOur objective in this case study is to demonstrate an alternative approach to screening the results retrieved by Google Search which is based on our experience that the viewable number of results is often far fewer than the estimated number calculated by the search engine.MethodsWe screened the results of three searches of Google Search using our approach, which involves increasing the number of results displayed per page from 10 to the maximum of 100. We then calculated the viewable number of results and compared this with the estimated number.ResultsThe mean of the estimated number of results for the three searches was 569,454,000. The mean of the viewable number results was 463 (0.00008% of the mean of the estimated number of results).ConclusionOur findings challenge the commonly reported view that the number of results retrieved when using Google Search is too high to screen in full.

Over the last decade, there has been a proliferation of published meta-ethnographies. Yet, strategies and techniques for updating have not received the same attention, rendering answers to important methodological questions still elusive. One such question has to do with who can perform an update. Although it is not uncommon for quantitative systematic reviews and statistical meta-analyses to be updated by different reviewers, qualitative synthesists might find themselves caught between a rock and a hard place. On the one hand, as meta-ethnography constitutes an interpretation three times removed from the lived experience of the participants in the original studies, it could be argued that an update by different reviewers might add an extra layer of interpretation. By comparison, updating by the same reviewers could give rise to concerns about the robustness of updated findings, as an implicit drive for making new data fit the original work might be difficult to control for. We recently reported the findings of our attempt to update an earlier meta-ethnography of primary care antibiotic prescribing, conducted by a different team of reviewers. In this article, we wish to contribute to the emerging debate on the necessity of promoting a culture of updating in qualitative evidence synthesis, by discussing some of the practical and methodological issues we considered at each stage of the process and offering lessons learnt from our experience.

Background: By 2030, the global population of people older than 60 years is expected to be higher than the number of children under 10 years, resulting in major health and social care system implications worldwide. Without a supportive environment, whether social or built, diminished functional ability may arise in older people. Functional ability comprises an individual's intrinsic capacity and people's interaction with their environment enabling them to be and do what they value. Objectives: This evidence and gap map aims to identify primary studies and systematic reviews of health and social support services as well as assistive devices designed to support functional ability among older adults living at home or in other places of residence. Search Methods: We systematically searched from inception to August 2018 in: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, CENTRAL, CINAHL, PsycINFO, AgeLine, Campbell Library, ASSIA, Social Science Citation Index and Social Policy & Practice. We conducted a focused search for grey literature and protocols of studies (e.g. ProQuest Theses and Dissertation Global, conference abstract databases, Help Age, PROSPERO, Cochrane and Campbell libraries and ClinicalTrials.gov). Selection Criteria: Screening and data extraction were performed independently in duplicate according to our intervention and outcome framework. We included completed and on-going systematic reviews and randomized controlled trials of effectiveness on health and social support services provided at home, assistive products and technology for personal indoor and outdoor mobility and transportation as well as design, construction and building products and technology of buildings for private use such as wheelchairs, and ramps. Data Collection and Analysis: We coded interventions and outcomes, and the number of studies that assessed health inequities across equity factors. We mapped outcomes based on the International Classification of Function, Disability and Health (ICF) adapted categories: intrinsic capacities (body function and structures) and functional abilities (activities). We assessed methodological quality of systematic reviews using the AMSTAR II checklist. Main Results: After de-duplication, 10,783 records were screened. The map includes 548 studies (120 systematic reviews and 428 randomized controlled trials). Interventions and outcomes were classified using domains from the International Classification of Function, Disability and Health (ICF) framework. Most systematic reviews (n = 71, 59%) were rated low or critically low for methodological quality. The most common interventions were home-based rehabilitation for older adults (n = 276) and home-based health services for disease prevention (n = 233), mostly delivered by visiting healthcare professionals (n = 474). There was a relative paucity of studies on personal mobility, building adaptations, family support, personal support and befriending or friendly visits. The most measured intrinsic capacity domains were mental function (n = 269) and neuromusculoskeletal function (n = 164). The most measured outcomes for functional ability were basic needs (n = 277) and mobility (n = 160). There were few studies which evaluated outcome domains of social participation, financial security, ability to maintain relationships and communication. There was a lack of studies in low- and middle-income countries (LMICs) and a gap in the assessment of health equity issues. Authors' Conclusions: There is substantial evidence for interventions to promote functional ability in older adults at home including mostly home-based rehabilitation for older adults and home-based health services for disease prevention. Remotely delivered home-based services are of greater importance to policy-makers and practitioners in the context of the COVID-19 pandemic. This map of studies published prior to the pandemic provides an initial resource to identify relevant home-based services which may be of interest for policy-makers and practitioners, such as home-based rehabilitation and social support, although these interventions would likely require further adaptation for online delivery during the COVID-19 pandemic. There is a need to strengthen assessment of social support and mobility interventions and outcomes related to making decisions, building relationships, financial security, and communication in future studies. More studies are needed to assess LMIC contexts and health equity issues.

This is the protocol for a Campbell review. The aim of this study is to comprehensively assess the quality and nature of the search methods and reporting across Campbell systematic reviews. The search methods used in systematic reviews provide the foundation for establishing the body of literature from which conclusions are drawn and recommendations made. Searches should be comprehensive and reporting of search methods should be transparent and reproducible. Campbell Collaboration systematic reviews strive to adhere to the best methodological guidance available for this type of searching. The current work aims to provide a comprehensive assessment of the quality of the search methods and reporting in Campbell Collaboration systematic reviews. Our specific objectives include the following: to examine how searches are currently conducted in Campbell systematic reviews. To identify any machine learning or automation methods used, or emerging and less commonly used approaches to web searching. To examine how search strategies, search methods and search reporting adhere to the Methodological Expectations of Campbell Collaboration Intervention Reviews (MECCIR) and PRISMA guidelines. The findings will be used to identify opportunities for advancing current practices in Campbell reviews through updated guidance, peer review processes and author training and support.

BACKGROUND: Systematic reviews are comprehensive, robust, inclusive, transparent, and reproducible when bringing together the evidence to answer a research question. Various guidelines provide recommendations on the expertise required to conduct a systematic review, where and how to search for literature, and what should be reported in the published review. However, the finer details of the search results are not typically reported to allow the search methods or search efficiency to be evaluated. CASE PRESENTATION: This case study presents a search summary table, containing the details of which databases were searched, which supplementary search methods were used, and where the included articles were found. It was developed and published alongside a recent systematic review. This simple format can be used in future systematic reviews to improve search results reporting. CONCLUSIONS: Publishing a search summary table in all systematic reviews would add to the growing evidence base about information retrieval, which would help in determining which databases to search for which type of review (in terms of either topic or scope), what supplementary search methods are most effective, what type of literature is being included, and where it is found. It would also provide evidence for future searching and search methods research.

BACKGROUND: an increasingly high number of patients admitted to hospital have dementia. Hospital environments can be particularly confusing and challenging for people living with dementia (Plwd) impacting their wellbeing and the ability to optimize their care. Improving the experience of care in hospital has been recognized as a priority, and non-pharmacological interventions including activity interventions have been associated with improved wellbeing and behavioral outcomes for Plwd in other settings. This systematic review aimed at evaluating the effectiveness of activity interventions to improve experience of care for Plwd in hospital. METHODS: Systematic searches were conducted in 16 electronic databases up to October 2019. Reference lists of included studies and forward citation searching were also conducted. Quantitative studies reporting comparative data for activity interventions delivered to Plwd aiming to improve their experience of care in hospital were included. Screening for inclusion, data extraction and quality appraisal were performed independently by two reviewers with discrepancies resolved by discussion with a third where necessary. Standardized mean differences (SMDs) were calculated where possible to support narrative statements and aid interpretation. RESULTS: Six studies met the inclusion criteria (one randomized and five non-randomized uncontrolled studies) including 216 Plwd. Activity interventions evaluated music, art, social, psychotherapeutic, and combinations of tailored activities in relation to wellbeing outcomes. Although studies were generally underpowered, findings indicated beneficial effects of activity interventions with improved mood and engagement of Plwd while in hospital, and reduced levels of responsive behaviors. Calculated SMDs ranged from very small to large but were mostly statistically non-significant. CONCLUSIONS: the small number of identified studies indicate that activity-based interventions implemented in hospitals may be effective in improving aspects of the care experience for Plwd. Larger well-conducted studies are needed to fully evaluate the potential of this type of non-pharmacological intervention to improve experience of care in hospital settings, and whether any benefits extend to staff wellbeing and the wider ward environment.

BACKGROUND: the search for studies for a systematic review should be conducted systematically and reported transparently to facilitate reproduction. This study aimed to report on the conduct and reporting of backward citation searching (ie, checking reference lists) and forward citation searching in a cross section of Cochrane reviews. Citation searching uses the citation network surrounding a source study to identify additional studies. METHODS: Cochrane reviews were identified by searching the Cochrane Database of Systematic Reviews using the wildcard symbol and date limiting to the 3-month period November 2016 to January 2017. Cochrane reviews thus identified were screened for mention of citation searching. Descriptive detail on the conduct and reporting of citation searching was captured in data extraction forms and described and evaluated. RESULTS: Two hundred fifteen Cochrane reviews were identified. One hundred seventy-two reviews reported backward citation searching, and 18 reviews reported forward citation searching. Web of Science was the most frequently reported citation index. The studies used for backward citation searching consisted mainly of studies meeting the inclusion criteria. One-third of reviews that reported forward citation searching used selected studies of importance. Reporting of citation searching was compliant with the Methodological Expectations of Cochrane Intervention Reviews (MECIR) standards, but full transparency requires additional detail that only a minority of reviews reported. CONCLUSION: the conduct of backward citation searching was more uniform than forward citation searching. This might be due to lack of MECIR guidance for forward citation searching. Reporting was generally compliant with MECIR, but this is not always sufficient to ensure full transparency.

BACKGROUND: Medication mismanagement is a major cause of both hospital admission and nursing home placement of frail older adults. Medication reviews by community pharmacists aim to maximise therapeutic benefit but also minimise harm. Pharmacist-led medication reviews have been the focus of several systematic reviews, but none have focussed on the home setting. REVIEW METHODS: to determine the effectiveness of pharmacist home visits for individuals at risk of medication-related problems we undertook a systematic review and meta-analysis of randomised controlled trials (RCTs). Thirteen databases were searched from inception to December 2018. Forward and backward citation of included studies was also performed. Articles were screened for inclusion independently by two reviewers. Randomised controlled studies of home visits by pharmacists for individuals at risk of medication-related problems were eligible for inclusion. Data extraction and quality appraisal were performed by one reviewer and checked by a second. Random-effects meta-analyses were performed where sufficient data allowed and narrative synthesis summarised all remaining data. RESULTS: Twelve RCTs (reported in 15 articles), involving 3410 participants, were included in the review. The frequency, content and purpose of the home visit varied considerably. The data from eight trials were suitable for meta-analysis of the effects on hospital admissions and mortality, and from three trials for the effects on quality of life. Overall there was no evidence of reduction in hospital admissions (risk ratio (RR) of 1.01 (95%CI 0.86 to 1.20, I2 = 69.0%, p = 0.89; 8 studies, 2314 participants)), or mortality (RR of 1.01 (95%CI 0.81 to 1.26, I2 = 0%, p = 0.94; 8 studies, 2314 participants)). There was no consistent evidence of an effect on quality of life, medication adherence or knowledge. CONCLUSION: a systematic review of twelve RCTs assessing the impact of pharmacist home visits for individuals at risk of medication related problems found no evidence of effect on hospital admission or mortality rates, and limited evidence of effect on quality of life. Future studies should focus on using more robust methods to assess relevant outcomes.

OBJECTIVE: to identify and appraise published evidence of the measurement properties for epilepsy-specific patient-reported outcome measures (PROMs) of children's health-related quality of life (HRQoL). METHODS: We searched multiple databases for studies evaluating the measurement properties of English-language epilepsy-specific PROMs of children's HRQoL. We assessed the methodological quality using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidance. We extracted data about the content validity, construct validity, internal consistency, test-retest reliability, proxy reliability, responsiveness, and precision, and assessed the measurement properties with reference to standardized criteria. RESULTS: We identified 27 papers that evaluated 11 PROMs. Methodological quality was variable. Construct validity, test-retest reliability, and internal consistency were more commonly assessed. Quality of Life in Childhood Epilepsy (QoLCE) questionnaires are parent-reported and evaluated more than other PROMs; QoLCE-55 has good and replicated evidence for structural and construct validity and internal consistency. Health-Related Quality of Life Measure for Children with Epilepsy (CHEQoL) has both child and parent-reported versions and good evidence of content, structural, and construct validity. SIGNIFICANCE: This review identified two leading candidate epilepsy-specific PROMs for measuring health-related quality of life in children. Establishing evidence of the responsiveness of PROMs is a priority to help the interpretation of meaningful change scores.

Under-identification of mental health difficulties (MHD) in children and young people contributes to the significant unmet need for mental health care. School-based programmes have the potential to improve identification rates. This systematic review aimed to determine the feasibility of various models of school-based identification of MHD. We conducted systematic searches in Medline, Embase, PsycINFO, ERIC, British Education Index, and ASSIA using terms for mental health combined with terms for school-based identification. We included studies that assessed feasibility of school-based identification of students in formal education aged 3-18 with MHD, symptomatology of MHD, or exposed to risks for MHD. Feasibility was defined in terms of (1) intervention fit, (2) cost and resource implications, (3) intervention complexity, flexibility, manualisation, and time concerns, and (4) adverse events. Thirty-three studies met inclusion criteria. The majority focused on behavioural and socioemotional problems or suicide risk, examined universal screening models, and used cross-sectional designs. In general, school-based programmes for identifying MHD aligned with schools' priorities, but their appropriateness for students varied by condition. Time, resource, and cost concerns were the most common barriers to feasibility across models and conditions. The evidence base regarding feasibility is limited, and study heterogeneity prohibits definitive conclusions about the feasibility of different identification models. Education, health, and government agencies must determine how to allocate available resources to make the widespread adoption of school-based identification programmes more feasible. Furthermore, the definition and measurement of feasibility must be standardised to promote any future comparison between models and conditions.

BACKGROUND: Missed hospital outpatient appointments is a commonly reported problem in healthcare services around the world; for example, they cost the National Health Service (NHS) in the UK millions of pounds every year and can cause operation and scheduling difficulties worldwide. In 2002, the World Health Organization (WHO) published a report highlighting the need for a model of care that more readily meets the needs of people with chronic conditions. Patient-initiated appointment systems may be able to meet this need at the same time as improving the efficiency of hospital appointments. OBJECTIVES: to assess the effects of patient-initiated appointment systems compared with consultant-led appointment systems for people with chronic or recurrent conditions managed in secondary care. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and six other databases. We contacted authors of identified studies and conducted backwards and forwards citation searching. We searched for current/ongoing research in two trial registers. Searches were run on 13 March 2019. SELECTION CRITERIA: We included randomised trials, published and unpublished in any language that compared the use of patient-initiated appointment systems to consultant-led appointment systems for adults with chronic or recurrent conditions managed in secondary care if they reported one or more of the following outcomes: physical measures of health status or disease activity (including harms), quality of life, service utilisation or cost, adverse effects, patient or clinician satisfaction, or failures of the 'system'. DATA COLLECTION AND ANALYSIS: Two review authors independently screened all references at title/abstract stage and full-text stage using prespecified inclusion criteria. We resolved disagreements though discussion. Two review authors independently completed data extraction for all included studies. We discussed and resolved discrepancies with a third review author. Where needed, we contacted authors of included papers to provide more information. Two review authors independently assessed the risk of bias using the Cochrane Effective Practice and Organisation of Care 'Risk of bias' tool, resolving any discrepancies with a third review author. Two review authors independently assessed the certainty of the evidence using GRADE. MAIN RESULTS: the 17 included randomised trials (3854 participants; mean age 41 to 76 years; follow-up 12 to 72 months) covered six broad health conditions: cancer, rheumatoid arthritis, asthma, chronic obstructive pulmonary disease, psoriasis and inflammatory bowel disease. The certainty of the evidence using GRADE ratings was mainly low to very low. The results suggest that patient-initiated clinics may make little or no difference to anxiety (odds ratio (OR) 0.87, 95% confidence interval (CI) 0.68 to 1.12; 5 studies, 1019 participants; low-certainty evidence) or depression (OR 0.79 95% CI 0.51 to 1.23; 6 studies, 1835 participants; low-certainty evidence) compared to the consultant-led appointment system. The results also suggest that patient-initiated clinics may make little or no difference to quality of life (standardised mean difference (SMD) 0.12, 95% CI 0.00 to 0.25; 7 studies, 1486 participants; low-certainty evidence) compared to the consultant-led appointment system. Results for service utilisation (contacts) suggest there may be little or no difference in service utilisation in terms of contacts between the patient-initiated and consultant-led appointment groups; however, the effect is not certain as the rate ratio ranged from 0.68 to 3.83 across the studies (median rate ratio 1.11, interquartile (IQR) 0.93 to 1.37; 15 studies, 3348 participants; low-certainty evidence). It is uncertain if service utilisation (costs) are reduced in the patient-initiated compared to the consultant-led appointment groups (8 studies, 2235 participants; very low-certainty evidence). The results suggest that adverse events such as relapses in some conditions (inflammatory bowel disease and cancer) may have little or no reduction in the patient-initiated appointment group in comparison with the consultant-led appointment group (MD -0.20, 95% CI -0.54 to 0.14; 3 studies, 888 participants; low-certainty evidence). The results are unclear about any differences the intervention may make to patient satisfaction (SMD 0.05, 95% CI -0.41 to 0.52; 2 studies, 375 participants) because the certainty of the evidence is low, as each study used different questions to collect their data at different time points and across different health conditions. Some areas of risk of bias across all the included studies was consistently high (i.e. for blinding of participants and personnel and blinding of outcome assessment, other areas were largely of low risk of bias or were affected by poor reporting making the assessment unclear). AUTHORS' CONCLUSIONS: Patient-initiated appointment systems may have little or no effect on patient anxiety, depression and quality of life compared to consultant-led appointment systems. Other aspects of disease status and experience also appear to show little or no difference between patient-initiated and consultant-led appointment systems. Patient-initiated appointment systems may have little or no effect on service utilisation in terms of service contact and there is uncertainty about costs compared to consultant-led appointment systems. Patient-initiated appointment systems may have little or no effect on adverse events such as relapse or patient satisfaction compared to consultant-led appointment systems.

BACKGROUND: Forwards citation searching is a valuable method for finding relevant studies in reviews where concepts are not clearly defined. Scopus and Web of Science can both be used for forwards citation searching but there is little evidence comparing the resources for this purpose. METHOD: 104 source records relevant to a scoping review of implementation and dissemination strategies in dementia care were checked for inclusion on Web of Science and Scopus. The number of citing references was recorded. Where citing references appeared unique to one of the resources, they were checked for inclusion on the other resource to assess the performance of citation links. RESULTS: 1397 citing references were returned by Scopus and 1010 were returned by Web of Science. For the unique citing references returned by Web of Science (n = 52), 36 were subsequently found to be on Scopus but had failed to be picked up as citing a source record. of the unique citing references returned by Scopus (n = 355), 83 were found to be on Web of Science but had failed to be picked up as citing a source record. 26 additional relevant records were identified for the review by forwards citation searching. All were found on Scopus; six would have been missed by searching Web of Science alone. CONCLUSION: Citation searching using Scopus alone would have found all additional relevant studies for the review. Both Scopus and Web of Science failed to return all citing references from the source records, even where they were present on the database, indicating poor links between citations.

. We undertook three systematic reviews: (1) the experience of care in hospital, (2) the experience of interventions to improve care in hospital and (3) the effectiveness and cost-effectiveness of interventions to improve the experience of care. Reviews 1 and 2 sought primary qualitative studies and were analysed using meta-ethnography. Review 3 sought comparative studies and economic evaluations of interventions to improve experience of care. An interweaving approach to overarching synthesis was used to integrate the findings across the reviews.

. Data sources
. Sixteen electronic databases were searched. Forwards and backwards citation chasing, author contact and grey literature searches were undertaken. Screening of title and abstracts and full texts was performed by two reviewers independently. A quality appraisal of all included studies was undertaken.

.
. Results
. Sixty-three studies (reported in 82 papers) were included in review 1, 14 studies (reported in 16 papers) were included in review 2, and 25 studies (reported in 26 papers) were included in review 3. A synthesis of review 1 studies found that when staff were delivering more person-centred care, people living with dementia, carers and staff all experienced this as better care. The line of argument, which represents the conceptual findings as a whole, was that ‘a change of hospital culture is needed before person-centred care can become routine’. From reviews 2 and 3, there was some evidence of improvements in experience of care from activities, staff training, added capacity and inclusion of carers. In consultation with internal and external stakeholders, the findings from the three reviews and overarching synthesis were developed into 12 DEMENTIA CARE pointers for service change: key institutional and environmental practices and processes that could help improve experience of care for people living with dementia in hospital.
.
.
. Limitations
. Few of the studies explored experience from the perspectives of people living with dementia. The measurement of experience of care across the studies was not consistent. Methodological variability and the small number of intervention studies limited the ability to draw conclusions on effectiveness.
.
.
. Conclusions
. The evidence suggests that, to improve the experience of care in hospital for people living with dementia, a transformation of organisational and ward cultures is needed that supports person-centred care and values the status of dementia care. Changes need to cut across hierarchies and training systems to facilitate working patterns and interactions that enable both physical and emotional care of people living with dementia in hospital. Future research needs to identify how such changes can be implemented, and how they can be maintained in the long term. To do this, well-designed controlled studies with improved reporting of methods and intervention details to elevate the quality of available evidence and facilitate comparisons across different interventions are required.

OBJECTIVE: Establishing a core set of outcomes to be evaluated and reported in intervention trials aims to improve the usefulness of health research. There is no established core outcome set (COS) for childhood epilepsies. The aim of this study was to select a COS to be used in evaluative research of interventions for children with rolandic epilepsy (RE). METHODS: We followed guidance from the COMET (Core Outcome Measures in Effectiveness Trials) Initiative. First, we identified outcomes that had been measured in research through a systematic review. Second, young people with RE, parents, and professionals were invited to take part in a Delphi survey in which participants rated the importance of candidate outcomes. Last, a face-to-face meeting was convened to seek consensus on which outcomes were critical to include and to ratify the final COS. RESULTS: from 37 eligible papers in the review, we identified and included 48 candidate outcomes in the survey. We sent invitations to 165 people registered to take part in the survey; of these, 102 (62%) completed Round 1, and 80 (78%) completed Round 2 (three young people, 16 parents, 61 professionals). In Round 2 we included four additional outcomes suggested by participants in Round 1. The consensus meeting included two young people, four parents, and nine professionals who were eligible to vote and ratified the COS as 39 outcomes across 10 domains. SIGNIFICANCE: Our methodology was a proportionate and pragmatic approach toward producing a COS for evaluating research on interventions aiming to improve the health of children with RE.

This is a protocol for a Campbell Evidence and Gap Map. The objectives are to identify and assess the available evidence on health, social care and technological interventions to improve functional ability among older adults.

Introduction: Sleep positioning systems are often prescribed as part of a 24-hour postural management programme for children and adults with neurodisabilities. In a search for evidence of effectiveness for children with cerebral palsy a recent Cochrane review found two randomised controlled trials. This review aims to appraise a broader set of studies including any neurological diagnosis and users of all ages to inform therapists about the quality of the evidence underlying practice. Method: a comprehensive search for all peer-reviewed studies that evaluated the use of sleep positioning systems was conducted in MEDLINE, EMBASE, CINAHL, Cochrane Library databases, BNI, HMIC, PEDro, OTSeeker and clinical trials registries. Disability organisations, manufacturers and colleagues worldwide were also contacted. Titles were screened for relevance by two reviewers. Data were extracted into bespoke quantitative or qualitative forms by one reviewer and checked by a second. Findings were analysed into simple themes. Results: a total of 14 studies were eligible for inclusion; all were small and most were of low quality. Inferences of benefits cannot be made from the literature but also no harm was found. Conclusions: the body of evidence supporting practice remains small and mostly of low quality. Therapists should remain cautious when presenting the benefits to families.

BackgroundReducing unnecessary prescribing remains a key priority for tackling the global rise of antibiotic-resistant infections.AimThe authors sought to update a 2011 qualitative synthesis of GPs’ experiences of antibiotic prescribing for acute respiratory tract infections (ARTIs), including their views of interventions aimed at more prudent prescribing. They expanded the original scope to encompass all primary care professionals (PCPs) who can prescribe or dispense antibiotics for ARTIs (for example, nurses and pharmacists).Design and settingSystematic review and meta-ethnography of qualitative studies.MethodA systematic search was conducted on MEDLINE, EMBASE, PsycINFO, CINAHL, ASSIA, and Web of Science. No date or language restrictions were used. Identified studies were grouped according to their thematic focus (usual care versus intervention), and two separate syntheses were performed.ResultsIn all, 53 articles reporting the experiences of >1200 PCPs were included. Analysis of usual-care studies showed that PCPs tend to assume multiple roles in the context of ARTI consultations (the expert self, the benevolent self, the practical self), depending on the range of intrapersonal, interpersonal, and contextual situations in which they find themselves. Analysis of intervention studies identified four possible ways in which PCPs may experience quality improvement interventions (compromise, ‘supportive aids’, source of distress, and unnecessary).ConclusionContrary to the original review, these results suggest that the use of the same intervention is experienced in a totally different way by different PCPs, and that the same elements that are perceived as benefits by some could be viewed as drawbacks by others. Acceptability of interventions is likely to increase if these are context sensitive and take into account PCPs’ varying roles and changing priorities.

OBJECTIVE: Children and young people (CYP) with cancer undergo painful and distressing procedures. We aimed to systematically review the effectiveness of nonpharmacological interventions to reduce procedural anxiety in CYP. METHODS: Extensive literature searches sought randomised controlled trials that quantified the effect of any nonpharmacological intervention for procedural anxiety in CYP with cancer aged 0 to 25. Study selection involved independent title and abstract screening and full text screening by two reviewers. Anxiety, distress, fear, and pain outcomes were extracted from included studies. Where similar intervention, comparator, and outcomes presented, meta-analysis was performed, producing pooled effect sizes (Cohen's d) and 95% confidence intervals (95% CI). All other data were narratively described. Quality and risk of bias appraisal was performed, based on the Cochrane risk of bias tool. RESULTS: Screening of 11 727 records yielded 56 relevant full texts. There were 15 included studies, eight trialling hypnosis, and seven nonhypnosis interventions. There were large, statistically significant reductions in anxiety and pain for hypnosis, particularly compared with treatment as usual (anxiety: d = 2.30; 95% CI, 1.30-3.30; P 

BACKGROUND: Qualitative research in dementia improves understanding of the experience of people affected by dementia. Searching databases for qualitative studies is problematic. Qualitative-specific search strategies might help with locating studies. OBJECTIVE: to examine the effectiveness (sensitivity and precision) of 5 qualitative strategies on locating qualitative research studies in dementia in 4 major databases (MEDLINE, EMBASE, PsycINFO, and CINAHL). METHODS: Qualitative dementia studies were checked for inclusion on MEDLINE, EMBASE, PsycINFO, and CINAHL. Five qualitative search strategies (subject headings, simple free-text terms, complex free-text terms, and 2 broad-based strategies) were tested for study retrieval. Specificity, precision and number needed to read were calculated. RESULTS: Two hundred fourteen qualitative studies in dementia were included. PsycINFO and CINAHL held the most qualitative studies out the 4 databases studied (N = 171 and 166, respectively) and both held unique records (N = 14 and 7, respectively). The controlled vocabulary strategy in CINAHL returned 96% (N = 192) of studies held; by contrast, controlled vocabulary in PsycINFO returned 7% (N = 13) of studies held. The broad-based strategies returned more studies (93-99%) than the other free-text strategies (22-82%). Precision ranged from 0.061 to 0.004 resulting in a number needed to read to obtain 1 relevant study ranging from 16 (simple free-text search in CINAHL) to 239 (broad-based search in EMBASE). CONCLUSION: Qualitative search strategies using 3 broad terms were more sensitive than long complex searches. The controlled vocabulary for qualitative research in CINAHL was particularly effective. Furthermore, results indicate that MEDLINE and EMBASE offer little benefit for locating qualitative dementia research if CINAHL and PSYCINFO are also searched.

BACKGROUND: There is increasing recognition that establishing a core set of outcomes to be evaluated and reported in trials of interventions for particular conditions will improve the usefulness of health research. There is no established core outcome set for childhood epilepsy. The aim of this work is to select a core outcome set to be used in evaluative research of interventions for children with rolandic epilepsy, as an exemplar of common childhood epilepsy syndromes. METHODS: First we will identify what outcomes should be measured; then we will decide how to measure those outcomes. We will engage relevant UK charities and health professional societies as partners, and convene advisory panels for young people with epilepsy and parents of children with epilepsy. We will identify candidate outcomes from a search for trials of interventions for childhood epilepsy, statutory guidance and consultation with our advisory panels. Families, charities and health, education and neuropsychology professionals will be invited to participate in a Delphi survey following recommended practices in the development of core outcome sets. Participants will be able to recommend additional outcome domains. Over three rounds of Delphi survey participants will rate the importance of candidate outcome domains and state the rationale for their decisions. Over the three rounds we will seek consensus across and between families and health professionals on the more important outcomes. A face-to-face meeting will be convened to ratify the core outcome set. We will then review and recommend ways to measure the shortlisted outcomes using clinical assessment and/or patient-reported outcome measures. DISCUSSION: Our methodology is a proportionate and pragmatic approach to expediently produce a core outcome set for evaluative research of interventions aiming to improve the health of children with epilepsy. A number of decisions have to be made when designing a study to develop a core outcome set including defining the scope, choosing which stakeholders to engage, most effective ways to elicit their views, especially children and a potential role for qualitative research.

BACKGROUND: Research involving the public as partners often proves difficult to locate due to the variations in terms used to describe public involvement, and inability of medical databases to index this concept effectively. OBJECTIVE: to design a search filter to identify literature where patient and public involvement (PPI) was used in health research. METHODS: a reference standard of 172 PPI papers was formed. The references were divided into a development set and a test set. Search terms were identified from common words, phrases and synonyms in the development set. These terms were combined as a search strategy for medline via OvidSP, which was then tested for sensitivity against the test set. The resultant search filter was then assessed for sensitivity, specificity and precision using a previously published systematic review. RESULTS: the search filter was found to be highly sensitive 98.5% in initial testing. When tested against results generated by a 'real-life' systematic review, the filter had a specificity of 81%. However, sensitivity dropped to 58%. Adjustments to the population group of terms increased the sensitivity to 73%. CONCLUSION: the PPI filter designed for medline via OvidSP could aid information specialists and researchers trying to find literature specific to PPI.

BACKGROUND: the need to better understand implementing evidence-informed dementia care has been recognised in multiple priority-setting partnerships. The aim of this scoping review was to give an overview of the state of the evidence on implementation and dissemination of dementia care, and create a systematic evidence map. METHODS: We sought studies that addressed dissemination and implementation strategies or described barriers and facilitators to implementation across dementia stages and care settings. Twelve databases were searched from inception to October 2015 followed by forward citation and grey literature searches. Quantitative studies with a comparative research design and qualitative studies with recognised methods of data collection were included. Titles, abstracts and full texts were screened independently by two reviewers with discrepancies resolved by a third where necessary. Data extraction was performed by one reviewer and checked by a second. Strategies were mapped according to the ERIC compilation. RESULTS: Eighty-eight studies were included (30 quantitative, 34 qualitative and 24 mixed-methods studies). Approximately 60% of studies reported implementation strategies to improve practice: training and education of professionals (94%), promotion of stakeholder interrelationships (69%) and evaluative strategies (46%) were common; financial strategies were rare (15%). Nearly 70% of studies reported barriers or facilitators of care practices primarily within residential care settings. Organisational factors, including time constraints and increased workload, were recurrent barriers, whereas leadership and managerial support were often reported to promote implementation. Less is known about implementation activities in primary care and hospital settings, or the views and experiences of people with dementia and their family caregivers. CONCLUSION: This scoping review and mapping of the evidence reveals a paucity of robust evidence to inform the successful dissemination and implementation of evidence-based dementia care. Further exploration of the most appropriate methods to evaluate and report initiatives to bring about change and of the effectiveness of implementation strategies is necessary if we are to make changes in practice that improve dementia care.

This systematic review and synthesis of qualitative research explored contextual factors relevant to non-pharmacological interventions for Attention Deficit Hyperactivity Disorder (ADHD) in schools. We conducted meta-ethnography to synthesise 34 studies, using theories of stigma to further develop the synthesis. Studies suggested that the classroom context requiring pupils to sit still, be quiet and concentrate could trigger symptoms of ADHD, and that symptoms could then be exacerbated through informal/formal labelling and stigma, damaged self-perceptions and resulting poor relationships with staff and pupils. Influences of the school context on symptoms of ADHD were often invisible to teachers and pupils, with most attributions made to the individual pupil and/or the pupil's family. We theorise that this ‘invisibility’ is at least partly an artefact of stigma, and that the potential for stigma for ADHD to seem ‘natural and right’ in the context of schools needs to be taken into account when planning any intervention.

OBJECTIVES: to evaluate the effectiveness of behaviour changing interventions targeting ordering of thyroid function tests. DESIGN: Systematic review. DATA SOURCES: MEDLINE, EMBASE and the Cochrane Database up to May 2015. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included studies evaluating the effectiveness of behaviour change interventions aiming to reduce ordering of thyroid function tests. Randomised controlled trials (RCTs), non-randomised controlled studies and before and after studies were included. There were no language restrictions. STUDY APPRAISAL AND SYNTHESIS METHODS: 2 reviewers independently screened all records identified by the electronic searches and reviewed the full text of any deemed potentially relevant. Study details were extracted from the included papers and their methodological quality assessed independently using a validated tool. Disagreements were resolved through discussion and arbitration by a third reviewer. Meta-analysis was not used. RESULTS: 27 studies (28 papers) were included. They evaluated a range of interventions including guidelines/protocols, changes to funding policy, education, decision aids, reminders and audit/feedback; often intervention types were combined. The most common outcome measured was the rate of test ordering, but the effect on appropriateness, test ordering patterns and cost were also measured. 4 studies were RCTs. The majority of the studies were of poor or moderate methodological quality. The interventions were variable and poorly reported. Only 4 studies reported unsuccessful interventions but there was no clear pattern to link effect and intervention type or other characteristics. CONCLUSIONS: the results suggest that behaviour change interventions are effective particularly in reducing the volume of thyroid function tests. However, due to the poor methodological quality and reporting of the studies, the likely presence of publication bias and the questionable relevance of some interventions to current day practice, we are unable to draw strong conclusions or recommend the implementation of specific intervention types. Further research is thus justified. TRIAL REGISTRATION NUMBER: CRD42014006192.

© 2016 SEBDA School-based non-pharmacological interventions are an important part of the treatment of attention-deficit/hyperactivity disorder (ADHD). We aimed to systematically review qualitative literature relating to the experience of and attitudes towards school-based non-pharmacological interventions for ADHD. Systematic searches of 20 electronic databases were undertaken. Reviewers screened titles, abstracts and full reports of studies, before extracting data and critically appraising 33 included papers. Studies were synthesised using meta-ethnographic methods. Four-key interrelated themes were identified: (1) individualising interventions, (2) structure of interventions, (3) barriers to effectiveness, (4) perceived moderators and impact of interventions. The perceived effectiveness of interventions used in school settings is reported to vary. Therefore, flexible, tailored interventions ought to hold potential. However, highly individualised interventions may negatively affect children with ADHD. Findings point to the need for school-based interventions to take into account the wider school context, as well as core symptoms of ADHD.

BACKGROUND: Bibliographic databases are a day-to-day tool of the researcher: they offer the researcher easy and organised access to knowledge, but how much is actually known about the databases on offer? the focus of this paper is UK health and social care databases. These databases are often small, specialised by topic, and provide a complementary literature to the large, international databases. There is, however, good evidence that these databases are overlooked in systematic reviews, perhaps because little is known about what they can offer. OBJECTIVES: to systematically locate and map, published and unpublished literature on the key UK health and social care bibliographic databases. METHODS: Systematic searching and mapping. RESULTS: Two hundred and forty-two items were identified which specifically related to the 24 of the 34 databases under review. CONCLUSION: There is little published or unpublished literature specifically analysing the key UK health and social care databases. Since several UK databases have closed, others are at risk, and some are overlooked in reviews, better information is required to enhance our knowledge. Further research on UK health and social care databases is required. This paper suggests the need to develop the evidence base through a series of case studies on each of the databases.

Educational policy and the school effectiveness movement often involve rhetoric about the benefit of parent involvement in schools, but high quality relationships between parents and teachers are not always straightforwardly achieved, and this may be particularly true for parents of children presenting with academic problems and/or Social, Emotional and Behavioural Difficulties (SEBD). A systematic review of qualitative research was conducted to explore the school-related experiences of parents of pupils diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). Six studies reported in seven papers met the inclusion criteria. High quality parent—teacher relationships were found to be the exception, with mothers feeling silenced and criticised. Findings show commonalities with wider research about parents, but identify additional grounds for conflict resulting from parental blame for a pupils’ disruptive behaviour, and the ambivalent nature of the concept of ADHD.

OBJECTIVE: to obtain summary estimates of the accuracy of a single baseline measurement of the Elecsys Troponin T high-sensitive assay (Roche Diagnostics) for the diagnosis of acute myocardial infarction in patients presenting to the emergency department. DESIGN: Systematic review and meta-analysis of diagnostic test accuracy studies. DATA SOURCES: Medline, Embase, and other relevant electronic databases were searched for papers published between January 2006 and December 2013. STUDY SELECTION: Studies were included if they evaluated the diagnostic accuracy of a single baseline measurement of Elecsys Troponin T high-sensitive assay for the diagnosis of acute myocardial infarction in patients presenting to the emergency department with suspected acute coronary syndrome. STUDY APPRAISAL AND DATA SYNTHESIS: the first author screened all titles and abstracts identified through the searches and selected all potentially relevant papers. The screening of the full texts, the data extraction, and the methodological quality assessment, using the adapted QUADAS-2 tool, were conducted independently by two reviewers with disagreements being resolved through discussion or arbitration. If appropriate, meta-analysis was conducted using the hierarchical bivariate model. RESULTS: Twenty three studies reported the performance of the evaluated assay at presentation. The results for 14 ng/L and 3-5 ng/L cut-off values were pooled separately. At 14 ng/L (20 papers), the summary sensitivity was 89.5% (95% confidence interval 86.3% to 92.1%) and the summary specificity was 77.1% (68.7% to 83.7%). At 3-5 ng/L (six papers), the summary sensitivity was 97.4% (94.9% to 98.7%) and the summary specificity was 42.4% (31.2% to 54.5%). This means that if 21 of 100 consecutive patients have the target condition (21%, the median prevalence across the studies), 2 (95% confidence interval 2 to 3) of 21 patients with acute myocardial infarction will be missed (false negatives) if 14 ng/L is used as a cut-off value and 18 (13 to 25) of 79 patients without acute myocardial infarction will test positive (false positives). If the 3-5 ng/L cut-off value is used,

Background
Health services are increasingly focused on measuring and monitoring outcomes, particularly those that reflect patients’ priorities. To be meaningful, outcomes measured should be valued by patients and carers, be consistent with what health professionals seek to achieve, and be robust in terms of measurement properties.

The aim of this study was (i) to seek a shared vision between families and clinicians regarding key aspects of health as outcomes, beyond mortality and morbidity, for children with neurodisability, and (ii) to appraise which multidimensional patient reported outcome measures (PROMs) could be used to assess salient health domains.

Methods
Relevant outcomes were identified from (i) qualitative research with children and young people with neurodisability and parent carers, (ii) Delphi survey with health professionals, and (iii) systematic review of PROMs. The International Classification of Functioning Disability and Health provided a common language to code aspects of health. A subset of stakeholders participated in a prioritisation meeting incorporating a Q-sorting task to discuss and rank aspects of health.

Results
A total of 33 pertinent aspects of health were identified. Fifteen stakeholders from the qualitative and Delphi studies participated in the prioritisation meeting: 3 young people, 5 parent carers, and 7 health professionals. Aspects of health that emerged as more important for families and targets for health professionals were: communication, emotional wellbeing, pain, sleep, mobility, self-care, independence, mental health, community and social life, behaviour, toileting and safety. Whilst available PROMs measure many aspects of health in the ICF, no single PROM captures all the key domains prioritised as for children and young people with neurodisability. The paucity of scales for assessing communication was notable.

Conclusions
We propose a core suite of key outcome domains for children with neurodisability that could be used in evaluative research, audit and as health service performance indicators. Future work could appraise domain-specific PROMs for these aspects of health; a single measure assessing the key aspects of health that could be applied across paediatric neurodisability remains to be developed.

Objective: This overarching synthesis brings together the findings of four systematic reviews including 138 studies focused on non-pharmacological interventions for ADHD used in school settings. These reviews considered the effectiveness of school-based interventions for ADHD, attitudes towards and experience of school-based interventions for ADHD, and the experience of ADHD in school settings. Method: We developed novel methods to compare the findings across these reviews inductively and deductively. Results: Key contextual issues that may influence the effectiveness and implementation of interventions include the relationships that pupils with ADHD have with their teachers and peers, the attributions individuals make about the etiology of ADHD, and stigma related to ADHD or intervention attendance. Conclusion: Although we found some positive effects for some outcomes and intervention categories, heterogeneity in effect size estimates and research evidence suggests a range of diverse contextual factors potentially moderate the implementation and effectiveness of school based interventions for ADHD.

BACKGROUND: Systematic reviews require literature searches that are precise, sensitive and often complex. Database-hosting platforms need to facilitate this type of searching in order to minimise errors and the risk of bias in the results. OBJECTIVES: the main objective of the study was to create a generic checklist of criteria to assess the ability of host platforms to cope with complex searching, for example, for systematic reviews, and to test the checklist against three host platforms (EBSCOhost, OvidSP and ProQuest). METHOD: the checklist was developed as usual review work was carried out and through discussion between the two authors. Attributes on the checklist were designated as 'desirable' or 'essential'. The authors tested the checklist independently against three host platforms and graded their performance from 1 (insufficient) to 3 (performs well). RESULTS: Fifty-five desirable or essential attributes were identified for the checklist. None of the platforms performed well for all of the attributes on the checklist. CONCLUSIONS: Not all database-hosting platforms are designed for complex searching. Librarians and other decision-makers who work in health research settings need to be aware of the different limitations of host platforms for complex searching when they are making purchasing decisions or training others.

OBJECTIVE: Elderly residents with dementia commonly exhibit increased agitation at mealtimes. This interferes with eating and can be distressing for both the individual and fellow residents. This review examines the effectiveness of mealtime interventions aimed at improving behavioral symptoms in elderly people living with dementia in residential care. DESIGN: Systematic review. DATA SOURCES: Medline, PsycINFO, Embase, HMIC, AMED (OvidSP); CDSR, CENTRAL, DARE (Cochrane Library, Wiley); CINAHL (EBSCOhost); British Nursing Index (NHS Evidence); ASSIA (ProQuest); Social Science Citation Index (Web of Knowledge); EThOS (British Library); Social Care Online and OpenGrey from inception to November 2012. Forward and backward citation chases, hand searches of other review articles identified in the search, and key journals. TYPES OF STUDY: all comparative studies were included. Articles were screened for inclusion independently by 2 reviewers. Data extraction and quality appraisal were performed by one reviewer and checked by a second with discrepancies resolved by discussion with a third if necessary. Data were not suitable for meta-analysis so narrative synthesis was carried out. RESULTS: a total of 6118 articles were identified in the original search. Eleven articles were finally included. Mealtime interventions were categorized into 4 types: music, changes to food service, dining environment alteration, and group conversation. Study quality was poor, making it difficult to reach firm conclusions. Although all studies showed a trend in favor of the intervention, only 6 reported a statistically significant improvement in behavioral symptoms. Four studies suggest cumulative or lingering effects of music on agitated and aggressive behaviors. CONCLUSION: There is some evidence to suggest that mealtime interventions improve behavioral symptoms in elderly people with dementia living in residential care, although weak study designs limit the generalizability of the findings. Well designed, controlled trials are needed to further understand the utility of mealtime interventions in this setting.

BACKGROUND: Antipsychotic medications are commonly used to manage the behavioral and psychological symptoms of dementia. Several large studies have demonstrated an association between treatment with antipsychotics and increased morbidity and mortality in people with dementia. AIMS: to assess the effectiveness of interventions used to reduce inappropriate prescribing of antipsychotics to the elderly with dementia in residential care. METHOD: Systematic searches were conducted in 12 electronic databases. Reference lists of all included studies and forward citation searching using Web of Science were also conducted. All quantitative studies with a comparative research design and studies in which recognized methods of qualitative data collection were used were included. Articles were screened for inclusion independently by 2 reviewers. Data extraction and quality appraisal were performed by 1 reviewer and checked by a second with discrepancies resolved by discussion with a third if necessary. RESULTS: Twenty-two quantitative studies (reported in 23 articles) were included evaluating the effectiveness of educational programs (n = 11), in-reach services (n = 2), medication review (n = 4), and multicomponent interventions (n = 5). No qualitative studies meeting our inclusion criteria were identified. Eleven studies were randomized or controlled in design; the remainder were uncontrolled before and after studies. Beneficial effects were seen in 9 of the 11 studies with the most robust study design with reductions in antipsychotic prescribing levels of between 12% and 20%. Little empirical information was provided on the sustainability of interventions. CONCLUSION: Interventions to reduce inappropriate prescribing of antipsychotic medications to people with dementia resident in care homes may be effective in the short term, but longer more robust studies are needed. For prescribing levels to be reduced in the long term, the culture and nature of care settings and the availability and feasibility of nondrug alternatives needs to be addressed.

The need to improve the nutrition of the elderly living in long term care has long been recognised, but how this can best be achieved, and whether (and which) intervention is successful in reducing morbidity is less well understood. The aim of this systematic review was to determine the effectiveness of mealtime interventions for the elderly living in residential care. Mealtime interventions were considered as those that aimed to change/improve the mealtime routine, practice, experience or environment. Following comprehensive searches, review and appraisal, 37 articles were included. Inadequate reporting in over half of the articles limited data quality appraisal. Mealtime interventions were categorised into five types: changes to food service, food improvement, dining environment alteration, staff training and feeding assistance. Meta-analysis found inconsistent evidence of effects on body weight of changes to food service (0.5 kg; 95% CI: -1.1 to 2.2; p=0.51), food improvement interventions (0.4 kg; 95% CI: -0.8 to 1.7; p=0.50) or alterations to dining environment (1.5 kg; 95% CI: -0.7 to 2.8; p=0.23). Findings from observational studies within these intervention types were mixed, but generally positive. Observational studies also found positive effects on food/caloric intake across all intervention types, though meta-analyses of randomised studies showed little evidence of any effects on food/caloric intake in food improvement studies (-5 kcal; 95% CI: -36 to 26; p=0.74). There was some evidence of an effect on daily energy intakes within dining environment studies (181 kcal/day, 95% CI: -5 to 367, p=0.06). The need to improve the nutrition of the elderly living in residential long term care is well recognised. This review found some evidence that simple intervention around various aspects of mealtime practices and the mealtime environment can result in favourable nutritional outcomes. Further large scale pragmatic trials, however, are still required to establish full efficacy of such interventions.

Background
Volunteering has been advocated by the United Nations, and American and European governments as a way to engage people in their local communities and improve social capital, with the potential for public health benefits such as improving wellbeing and decreasing health inequalities. Furthermore, the US Corporation for National and Community Service Strategic Plan for 2011–2015 focused on increasing the impact of national service on community needs, supporting volunteers’ wellbeing, and prioritising recruitment and engagement of underrepresented populations. The aims of this review were to examine the effect of formal volunteering on volunteers’ physical and mental health and survival, and to explore the influence of volunteering type and intensity on health outcomes.

Methods
Experimental and cohort studies comparing the physical and mental health outcomes and mortality of a volunteering group to a non-volunteering group were identified from twelve electronic databases (Cochrane Library, Medline, Embase, PsychINFO, CINAHL, ERIC, HMIC, SSCI, ASSIA, Social Care Online, Social Policy and Practice) and citation tracking in January 2013. No language, country or date restrictions were applied. Data synthesis was based on vote counting and random effects meta-analysis of mortality risk ratios.

Results
Forty papers were selected: five randomised controlled trials (RCTs, seven papers); four non-RCTs; and 17 cohort studies (29 papers). Cohort studies showed volunteering had favourable effects on depression, life satisfaction, wellbeing but not on physical health. These findings were not confirmed by experimental studies. Meta-analysis of five cohort studies found volunteers to be at lower risk of mortality (risk ratio: 0.78; 95% CI: 0.66, 0.90). There was insufficient evidence to demonstrate a consistent influence of volunteering type or intensity on outcomes.

Conclusion
Observational evidence suggested that volunteering may benefit mental health and survival although the causal mechanisms remain unclear. Consequently, there was limited robustly designed research to guide the development of volunteering as a public health promotion intervention. Future studies should explicitly map intervention design to clear health outcomes as well as use pragmatic RCT methodology to test effects.

This is the protocol for a review and there is no abstract. The objectives are as follows: to assess the effects of patient-initiated appointment systems compared with usual care in people with chronic or recurrent conditions managed in the secondary care setting. In particular, we are interested in whether these appointment systems can effectively manage disease without causing harm to patients and whether costs related to the provision of the service can be reduced compared with usual care.

AIM: to review the qualitative and quantitative evidence of the benefits of peer support for parents of children with disabling conditions in the context of health, well-being, impact on family, and economic and service implications. METHOD: We comprehensively searched multiple databases. Eligible studies evaluated parent-to-parent support and reported on the psychological health and experience of giving or receiving support. There were no limits on the child's condition, study design, language, date, or setting. We sought to aggregate quantitative data; findings of qualitative studies were combined using thematic analysis. Qualitative and quantitative data were brought together in a narrative synthesis. RESULTS: Seventeen papers were included: nine qualitative studies, seven quantitative studies, and one mixed-methods evaluation. Four themes were identified from qualitative studies: (1) shared social identity, (2) learning from the experiences of others, (3) personal growth, and (4) supporting others. Some quantitative studies reported a positive effect of peer support on psychological health and other outcomes; however, this was not consistently confirmed. It was not possible to aggregate data across studies. No costing data were identified. CONCLUSION: Qualitative studies strongly suggest that parents perceive benefit from peer support programmes, an effect seen across different types of support and conditions. However, quantitative studies provide inconsistent evidence of positive effects. Further research should explore whether this dissonance is substantive or an artefact of how outcomes have been measured.

INTRODUCTION: This protocol covers the first part of a two-part project funded by the Health Libraries Group and the University Health and Medical Librarians Group. It details the proposed methodology for a systematic map of the literature relating to UK bibliographic databases in the fields of health and social care. The aim of this mapping exercise is to consider ways in which UK bibliographic databases are described, considered and discussed in the published and unpublished literature. In doing so, we hope to gain a clearer sense of the ways in which UK bibliographic databases are used and viewed by the research community. It also enables the identification of any gaps in the literature for further research and discussion. This topic is important because UK databases are generally underused by researchers in the UK context and some databases are at risk of closure. A lack of access to UK databases means that researchers may miss relevant UK evidence when identifying an evidence base. METHOD: Systematic Map. ANALYSIS: the authors will present a narrative description of the literature relating to UK bibliographic databases in the fields of health and social care. They will use tables to present descriptive information about the literature (eg, frequency tables) and use cross-tabulations to demonstrate intersecting themes. Separately, guidance on how to use the resources (eg, areas of unique content, updating frequencies, unique truncation symbols) will be sought from stakeholders and reported alongside the report narrative as a guide to usage.

Disabled children are a broad group that includes those with complex, special or additional health needs as a result of chronic physical, cognitive, communication or behavioural problems. These children are more frequently admitted to hospital than other children; however, there appears to be relatively little research on their experience as inpatients. The aim of this structured review and synthesis was to integrate findings from qualitative studies reporting the experience of disabled children when they are hospital inpatients. Inclusion criteria were: qualitative studies that focused on the experience of children less than 18 years old, with a chronic health condition or neurodisability, during an inpatient stay. Studies of outpatient episodes or intensive care units were excluded. A systematic search identified relevant abstracts, selected papers were reviewed and data were extracted. The synthesis involved elucidating and integrating common themes. Eight relevant papers were identified; data were gathered from children, parents and staff. Communication between children and staff was a dominant theme and comprised giving the child information about their condition and appropriate involvement of the child/young person in discussions and decision making that affected them. Also important was communication between parents and staff, particularly around the division of care for their child. Other themes included emotions, particularly fears, the ward environment and confidence in staff. The review suggests that disabled children's experience as inpatients is not always optimal. Improving the communication skills of ward staff and providing information to disabled children and their families would improve disabled children's experience when they are inpatients. © 2012 Blackwell Publishing Ltd.
