Assessing Patient-Centred Outcomes in Lateral Elbow Tendinopathy: a Systematic Review and Standardised Comparison of English Language Clinical Rating Systems
© 2019, the Author(s). Background: Lateral elbow tendinopathy (LET) is a common condition affecting adults. Although a lack of treatment consensus continues to prompt numerous effectiveness studies, there is a paucity of clear guidance on the choice of outcome measure. Our aim was to undertake a standardised evaluation of the available clinical rating systems that report patient-centred outcomes in LET. Methods: a systematic review of studies reporting the development, assessment of metric properties and/or use of instruments aiming to quantify LET-specific patient-centred outcome measures was conducted in MEDLINE, Embase and CINAHL (inception-2017) adhering to PRISMA guidance. The evidence for each instrument was independently assessed by two reviewers using the standardised evaluating measures of patient-reported outcomes (EMPRO) method evaluating overall and attribute-specific instrument performance (metric properties and usability). EMPRO scores > 50/100 were considered indicative of high performance. Results: Out of 7261 references, we identified 105 articles reporting on 15 instruments for EMPRO analysis. Median performance score was 41.6 (range 21.6–72.5), with four instruments meeting high-performance criteria: quick Disabilities of the Arm Shoulder and Hand score (qDASH) (72.5), DASH (66.9), Oxford Elbow Score (OES) (66.6) and Patient-Rated Tennis Elbow Evaluation (PRTEE) (57.0). One hundred seventy-nine articles reported instrument use internationally with DASH as the most frequent (29.7% articles) followed by PRTEE (25.6%), MEPS (15.1%) and qDASH (8.1%). The correlation between frequency of use and performance was r = 0.35 (95%CI − 0.11; 0.83). Conclusions: This is the first study to provide standardised guidance on the choice of measures for LET. A large number of clinical rating systems are both available and being used for patients with LETs. Robust evidence is available for four measures, the DASH, QDASH, PRTEE and OES. The use of instruments in the literature is only in part explained by instrument performance.

Abstract:
Clinical rating systems in elbow research—a systematic review exploring trends and distributions of use
© 2018 Journal of Shoulder and Elbow Surgery Board of Trustees Background: Clinical rating systems are used as outcome measures in clinical trials and attempt to gauge the patient’s view of his or her own health. The choice of clinical rating system should be supported by its performance against established quality standards. Methods: a search strategy was developed to identify all studies that reported the use of clinical rating systems in the elbow literature. The strategy was run from inception in Medline Embase and CINHAL. Data extraction identified the date of publication, country of data collection, pathology assessed, and the outcome measure used. Results: We identified 980 studies that reported clinical rating system use. Seventy-two separate rating systems were identified. Forty-one percent of studies used ≥2 separate measures. Overall, 54% of studies used the Mayo Elbow Performance Score (MEPS). For arthroplasty, 82% used MEPS, 17% used Disabilities of Arm, Shoulder and Hand (DASH), and 7% used QuickDASH. For trauma, 66.7% used MEPS, 32% used DASH, and 23% used the Morrey Score. For tendinopathy, 31% used DASH, 23% used Patient-Rated Tennis Elbow Evaluation (PRTEE), and 13% used MEPS. Over time, there was an increased proportional use of the MEPS, DASH, QuickDASH, PRTEE, and the Oxford Elbow Score. Conclusions: This study identified a wide choice and usage of clinical rating systems in the elbow literature. Numerous studies reported measures without a history of either a specific pathology or cross-cultural validation. Interpretability and comparison of outcomes is dependent on the unification of outcome measure choice. This was not demonstrated currently.

Abstract:
General practitioner contributions to achieving sustained healthcare for offenders: a qualitative study.
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.

Abstract:
Personal well-being networks, social capital and severe mental illness: exploratory study.
BACKGROUND: Connectedness is a central dimension of personal recovery from severe mental illness (SMI). Research reports that people with SMI have lower social capital and poorer-quality social networks compared to the general population.AimsTo identify personal well-being network (PWN) types and explore additional insights from mapping connections to places and activities alongside social ties. METHOD: We carried out 150 interviews with individuals with SMI and mapped social ties, places and activities and their impact on well-being. PWN types were developed using social network analysis and hierarchical k-means clustering of this data. RESULTS: Three PWN types were identified: formal and sparse; family and stable; and diverse and active. Well-being and social capital varied within and among types. Place and activity data indicated important contextual differences within social connections that were not found by mapping social networks alone. CONCLUSIONS: Place locations and meaningful activities are important aspects of people's social worlds. Mapped alongside social networks, PWNs have important implications for person-centred recovery approaches through providing a broader understanding of individual's lives and resources.Declaration of interestNone.

Abstract:
Predicting Incident Multimorbidity.
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

Abstract:
Framework and guidance for implementing patient-reported outcomes in clinical practice: evidence, challenges and opportunities.
Patient-reported outcomes (PROs) are reports of the status of a patient's health condition that come directly from the patient. While PRO measures are a well-developed technology with robust standards in research, their use for informing healthcare decisions is still poorly understood. We review relevant examples of their application in the provision of healthcare and examine the challenges associated with implementing PROs in clinical settings. We evaluate evidence for their use and examine barriers to their uptake, and present an evidence-based framework for the successful implementation of PROs in clinical practice. We discuss current and future developments for the use of PROs in clinical practice, such as individualized measurement and computer-adaptive testing.

Abstract:
Routine provision of information on patient-reported outcome measures to healthcare providers and patients in clinical practice
This is the protocol for a review and there is no abstract. The objectives are as follows: to assess the impact of the routine use of patient-reported outcomes (PROs) in clinical practice on the process of care (including patient-physician communication, professionals awareness of patients' quality of life, diagnosis and recognition rates, treatment rates, health services and resource use, as well as patient behaviour); patients' and professionals' experiences of care; and health outcomes (both generic and disease-specific, using both routinely-used clinical measures and PROs).
