Evaluation of variation in special educational needs provision and its impact on health and education using administrative records for England: umbrella protocol for a mixed-methods research programme.

INTRODUCTION: One-third of children in England have special educational needs (SEN) provision recorded during their school career. The proportion of children with SEN provision varies between schools and demographic groups, which may reflect variation in need, inequitable provision and/or systemic factors. There is scant evidence on whether SEN provision improves health and education outcomes. METHODS: The Health Outcomes of young People in Education (HOPE) research programme uses administrative data from the Education and Child Health Insights from Linked Data-ECHILD-which contains data from all state schools, and contacts with National Health Service hospitals in England, to explore variation in SEN provision and its impact on health and education outcomes. This umbrella protocol sets out analyses across four work packages (WP). WP1 defined a range of 'health phenotypes', that is health conditions expected to need SEN provision in primary school. Next, we describe health and education outcomes (WP1) and individual, school-level and area-level factors affecting variation in SEN provision across different phenotypes (WP2). WP3 assesses the impact of SEN provision on health and education outcomes for specific health phenotypes using a range of causal inference methods to account for confounding factors and possible selection bias. In WP4 we review local policies and synthesise findings from surveys, interviews and focus groups of service users and providers to understand factors associated with variation in and experiences of identification, assessment and provision for SEN. Triangulation of findings on outcomes, variation and impact of SEN provision for different health phenotypes in ECHILD, with experiences of SEN provision will inform interpretation of findings for policy, practice and families and methods for future evaluation. ETHICS AND DISSEMINATION: Research ethics committees have approved the use of the ECHILD database and, separately, the survey, interviews and focus groups of young people, parents and service providers. These stakeholders will contribute to the design, interpretation and communication of findings.

The patient voice: More than a tick box exercise?

BACKGROUND: Patient and public involvement (PPI) in healthcare professional education is important, yet publications often provide insufficient detail about the types of involvement patients undertake and the level of autonomy that they have. This study details the factors that promote or hinder PPI within a university healthcare professional education setting and the types of activities members conducted. METHODS: PPI activities were described and mapped against a framework for PPI in healthcare professional education. Semi-structured interviews with PPI group members explored the motivators, enablers and barriers that influence involvement. FINDINGS: The framework highlighted that the PPI group were involved in a range of activities, yet they received limited training for their role and were infrequently involved in planning the activities. When interviewed, PPI members did not consider that these factors were the important promoters or barriers to involvement, instead emphasising five themes: (1) their individual characteristics, (2) factors relating to the university organisation, (3) relationships between themselves, faculty and students, (4) time in their role and (5) evidence of their impact. DISCUSSION AND CONCLUSION: Supporting PPI members whilst working, rather than provision of formal training was considered most empowering for group members. This was mediated through having enough time in their role to develop supportive relationships with faculty, which in turn promoted self-confidence and increased autonomy. This should be considered when making PPI appointments. Small changes in processes during education planning can make it easier for PPI members to bring their own agenda forward and promote equity during education decision making.

Higher Arm Versus Lower Arm Systolic Blood Pressure and Cardiovascular Outcomes: a Meta-Analysis of Individual Participant Data From the INTERPRESS-IPD Collaboration.

BACKGROUND: Guidelines recommend measuring blood pressure (BP) in both arms, adopting the higher arm readings for diagnosis and management. Data to support this recommendation are lacking. We evaluated associations of higher and lower arm systolic BPs with diagnostic and treatment thresholds, and prognosis in hypertension, using data from the Inter-arm Blood Pressure Difference-Individual Participant Data Collaboration. METHODS: One-stage multivariable Cox regression models, stratified by study, were used to examine associations of higher or lower reading arm BPs with cardiovascular mortality, all-cause mortality, and cardiovascular events, in individual participant data meta-analyses pooled from 23 cohorts. Cardiovascular events were modelled for Framingham and atherosclerotic cardiovascular disease risk scores. Model fit was compared throughout using Akaike information criteria. Proportions reclassified across guideline recommended intervention thresholds were also compared. RESULTS: We analyzed 53 172 participants: mean age 60 years; 48% female. Higher arm BP, compared with lower arm, reclassified 12% of participants at either 130 or 140 mm Hg systolic BP thresholds (both P<0.001). Higher arm BP models fitted better for all-cause mortality, cardiovascular mortality, and cardiovascular events (all P<0.001). Higher arm BP models better predicted cardiovascular events with Framingham and atherosclerotic cardiovascular disease risk scores (both P<0.001) and reclassified 4.6% and 3.5% of participants respectively to higher risk categories compared with lower arm BPs). CONCLUSIONS: Using BP from higher instead of lower reading arms reclassified 12% of people over thresholds used to diagnose hypertension. All prediction models performed better when using the higher arm BP. Both arms should be measured for accurate diagnosis and management of hypertension. REGISTRATION: URL: https://www.

Epistemic justice in public involvement and engagement: Creating conditions for impact.

INTRODUCTION: Patient and public involvement in research is anchored in moral and epistemological rationales. Moral rationales relate to the public having a right to influence how knowledge about them is generated. Epistemological rationales relate to how research design and implementation can improve when informed by experiential, as well as technical, knowledge. In other words, public involvement can increase the epistemological resources of researchers, and contribute to research that is fit for purpose and has high external validity. METHODS: This article presents an analysis of 3 meetings and 11 interviews with public collaborators and researchers in three UK-based health research studies. Data comprised transcripts of audio-recorded research meetings and interviews with public collaborators and researchers. Data were first analysed to develop a data-informed definition of experiential knowledge, then thematically to investigate how this experiential knowledge was considered and received within the research space. RESULTS: At meetings, public collaborators shared their experiential knowledge as stories, comments, questions, answers and when referring to their own roles. They were aware of crossing a boundary from everyday life, and some adapted their contributions to fit within the research space. Although researchers and public collaborators made efforts to create an inclusive climate, obstacles to impact were identified. CONCLUSIONS: Considering experiential knowledge as a boundary object highlights that this knowledge has a different form to other kinds of knowledge that contribute to research. To enable impact from experiential knowledge, researchers need to create a space where public collaborators experience epistemic justice. PATIENT AND PUBLIC CONTRIBUTION: The Peninsula Public Engagement Group (PenPEG) was involved in the planning and conceptualization of the study, including the development of the ethics application and the interview schedules. One member of this group (Richard Fitzgerald) and one from outside the group (Leon Farmer), were full members of the author team and were involved in the data analysis. Leon Farmer has since become a member of PenPEG. Richard Fitzgerald and Leon Farmer were not involved in the three research studies sampled for this study. Sadly Richard Fitzgerald died during the course of this study.

How common is patient and public involvement (PPI)? Cross-sectional analysis of frequency of PPI reporting in health research papers and associations with methods, funding sources and other factors.

OBJECTIVES: Patient and public involvement (PPI) in health research is required by some funders and publications but we know little about how common it is. In this study we estimated the frequency of PPI inclusion in health research papers and analysed how it varied in relation to research topics, methods, funding sources and geographical regions. DESIGN: Cross-sectional. METHODS: Our sample consisted of 3000 research papers published in 2020 in a general health-research journal (BMJ Open) that requires a statement on whether studies included PPI. We classified each paper as 'included PPI' or 'did not include PPI' and analysed the association of this classification with location (country or region of the world), methods used, research topic (journal section) and funding source. We used adjusted regression models to estimate incident rate ratios of PPI inclusion in relation to these differences. RESULTS: 618 (20.6%) of the papers in our sample included PPI. The proportion of papers including PPI varied in relation to location (from 44.5% (95% CI 40.8% to 48.5%) in papers from the UK to 3.4% (95% CI 1.5% to 5.3%) in papers from China), method (from 38.6% (95% CI 27.1% to 50.1%) of mixed-methods papers to 5.3% (95% CI -1.9% to 12.5%) of simulation papers), topic (from 36.9% (95% CI 29.1% to 44.7%) of papers on mental health to 3.4% (95% CI -1.3% to 8.2%) of papers on medical education and training, and funding source (from 57.2% (95% CI 51.8% to 62.6%) in papers that received funding from the UK's National Institute for Health Research to 3.4% (95% CI 0.7% to 6.0%) in papers that received funding from a Chinese state funder). CONCLUSIONS: Most research papers in our sample did not include PPI and PPI inclusion varied widely in relation to location, methods, topic and funding source.

Measuring the cost-effectiveness of treatments for people with multiple sclerosis: Beyond quality-adjusted life-years.

BACKGROUND: It is a familiar story. A promising multiple sclerosis (MS) treatment clears the three regulatory hurdles of safety, quality and efficacy, only to fall at the fourth: cost-effectiveness. This has led to concerns about the validity of the measures typically used to quantify treatment effects in cost-effectiveness analyses and in 2012, in the United Kingdom, the National Institute for Health and Care Excellence called for an improvement in the cost-effectiveness framework for assessing MS treatments. OBJECTIVE AND METHODS: This review describes what is meant by cost-effectiveness in health/social care funding decision-making, and usual practice for assessing treatment benefits. RESULTS: We detail the use of the quality-adjusted life-year (QALY) in resource allocation decisions, and set out limitations of this approach in the context of MS. CONCLUSION: We conclude by highlighting methodological and policy developments which should aid addressing these limitations.

Moving through Motherhood: Involving the Public in Research to Inform Physical Activity Promotion throughout Pregnancy and Beyond.

Information received by women regarding physical activity during and after pregnancy often lacks clarity and may be conflicting and confusing. Without clear, engaging, accessible guidance centred on the experiences of pregnancy and parenting, the benefits of physical activity can be lost. We describe a collaborative process to inform the design of evidence-based, user-centred physical activity resources which reflect diverse experiences of pregnancy and early parenthood. Two iterative, collaborative phases involving patient and public involvement (PPI) workshops, a scoping survey (n = 553) and stakeholder events engaged women and maternity, policy and physical activity stakeholders to inform pilot resource development. These activities shaped understanding of challenges experienced by maternity and physical activity service providers, pregnant women and new mothers in relation to supporting physical activity. Working collaboratively with women and stakeholders, we co-designed pilot resources and identified important considerations for future resource development. Outcomes and lessons learned from this process will inform further work to support physical activity during pregnancy and beyond, but also wider health research where such collaborative approaches are important. We hope that drawing on our experiences and sharing outcomes from this work provide useful information for researchers, healthcare professionals, policy makers and those involved in supporting physical activity behaviour.

Arm Based on LEg blood pressures (ABLE-BP): can systolic leg blood pressure measurements predict systolic brachial blood pressure? Protocol for an individual participant data meta-analysis from the INTERPRESS-IPD Collaboration.

INTRODUCTION: Blood pressure (BP) is normally measured on the upper arm, and guidelines for the diagnosis and treatment of high BP are based on such measurements. Leg BP measurement can be an alternative when brachial BP measurement is impractical, due to injury or disability. Limited data exist to guide interpretation of leg BP values for hypertension management; study-level systematic review findings suggest that systolic BP (SBP) is 17 mm Hg higher in the leg than the arm. However, uncertainty remains about the applicability of this figure in clinical practice due to substantial heterogeneity. AIMS: To examine the relationship between arm and leg SBP, develop and validate a multivariable model predicting arm SBP from leg SBP and investigate the prognostic association between leg SBP and cardiovascular disease and mortality. METHODS AND ANALYSIS: Individual participant data (IPD) meta-analyses using arm and leg SBP measurements for 33 710 individuals from 14 studies within the Inter-arm blood pressure difference IPD (INTERPRESS-IPD) Collaboration. We will explore cross-sectional relationships between arm and leg SBP using hierarchical linear regression with participants nested by study, in multivariable models. Prognostic models will be derived for all-cause and cardiovascular mortality and cardiovascular events. ETHICS AND DISSEMINATION: Data originate from studies with prior ethical approval and consent, and data sharing agreements are in place-no further approvals are required to undertake the secondary analyses proposed in this protocol. Findings will be published in peer-reviewed journal articles and presented at conferences. A comprehensive dissemination strategy is in place, integrated with patient and public involvement.

Involving Patients in Health Economics Research: "The PACTS Principles".

Discussion of public and patient involvement (PPI) in health economics (HE) research is growing. There is much literature on PPI principles and standards, but little specifically regarding involving patients in HE research. Here, we outline "PACTS", a set of principles, developed with a PPI group, for considering patient involvement in HE research. Planning: Involvement is best built in to research plans from the outset. This includes setting specific goals for involvement activities, and clearly communicating the background and purpose of involvement. Approach selection: We describe two main approaches to involvement-discussion-based and task-based. Discussion-based approaches are useful for generating broad insights and revealing "unknown unknowns". Task-based approaches offer a more focused means of shedding light on "known unknowns". Continuous involvement: Involving patients throughout the research process and across a range of projects helps build expertise for patients and insight for HE researchers. Team building: Meaningful involvement creates a shared sense of ownership of the research and, over time, helps to develop a team ethos, enhancing the positive impacts of involvement. Sensitivity: HE research can be perceived as technical and impersonal. Addressing this requires sensitivity, clarity, and an honest and open approach. There is increased recognition that patient contributors are experts at providing a "lived experience" perspective, in the way that clinicians are experts at providing an overview of conditions and HEs are experts in the methodology of their discipline. We hope these "PACTS Principles" complement existing PPI approaches and provide a useful foundation for health economists considering patient involvement.

Associations Between Systolic Interarm Differences in Blood Pressure and Cardiovascular Disease Outcomes and Mortality: Individual Participant Data Meta-Analysis, Development and Validation of a Prognostic Algorithm: The INTERPRESS-IPD Collaboration.

Systolic interarm differences in blood pressure have been associated with all-cause mortality and cardiovascular disease. We undertook individual participant data meta-analyses to (1) quantify independent associations of systolic interarm difference with mortality and cardiovascular events; (2) develop and validate prognostic models incorporating interarm difference, and (3) determine whether interarm difference remains associated with risk after adjustment for common cardiovascular risk scores. We searched for studies recording bilateral blood pressure and outcomes, established agreements with collaborating authors, and created a single international dataset: the Inter-arm Blood Pressure Difference - Individual Participant Data (INTERPRESS-IPD) Collaboration. Data were merged from 24 studies (53 827 participants). Systolic interarm difference was associated with all-cause and cardiovascular mortality: continuous hazard ratios 1.05 (95% CI, 1.02-1.08) and 1.06 (95% CI, 1.02-1.11), respectively, per 5 mm Hg systolic interarm difference. Hazard ratios for all-cause mortality increased with interarm difference magnitude from a ≥5 mm Hg threshold (hazard ratio, 1.07 [95% CI, 1.01-1.14]). Systolic interarm differences per 5 mm Hg were associated with cardiovascular events in people without preexisting disease, after adjustment for Atherosclerotic Cardiovascular Disease (hazard ratio, 1.04 [95% CI, 1.00-1.08]), Framingham (hazard ratio, 1.04 [95% CI, 1.01-1.08]), or QRISK cardiovascular disease risk algorithm version 2 (QRISK2) (hazard ratio, 1.12 [95% CI, 1.06-1.18]) cardiovascular risk scores. Our findings confirm that systolic interarm difference is associated with increased all-cause mortality, cardiovascular mortality, and cardiovascular events. Blood pressure should be measured in both arms during cardiovascular assessment. A systolic interarm difference of 10 mm Hg is proposed as the upper limit of normal.

Public involvement in health research: what does 'good' look like in practice?

PLAIN ENGLISH SUMMARY: Background Patient and public involvement means researchers working with members of the public, patients or carers to jointly plan and carry out research.Aim This article is written by members of three involvement groups, and the university employees that they work with. We wanted to jointly reflect on what enables our collaborative work, and what the challenges are for everyone involved.What we did and how we did it We wanted to establish what the literature defines as 'good' public involvement and compare this with processes and practices in our involvement groups. We therefore carried out a literature review and each group met separately to discuss what characterises good involvement, and what the challenges are. From these discussions we developed a set of descriptions about each group. We compared the literature review findings with what came out of the discussions within the involvement groups.Findings Some of the involvement principles from the literature were similar to the priorities of the involvement groups. In addition, the groups identified characteristics of 'good' involvement practice that were not reported in the literature: passion and enthusiasm, informal and welcoming meeting spaces, and opportunities to share lived experiences. In this article we present examples of how principles for good involvement are practiced in these groups, and difficulties we have experienced. ABSTRACT: Background Patient and public involvement is important for producing relevant and accessible health research. Evidence of impact from involvement is growing, but there is also a need for research on how to create conditions for meaningful collaborations between researchers and public advisers.Objective We report on a co-produced self-reflective evaluation of involvement practices in three UK research programmes.Methods A structured review identified research-based principles for 'good' public involvement in research. In parallel, members of three involvement groups co-developed statements on how the groups work, and enablers and challenges to collaborative research. The author team analysed these statements using the findings from the review.Results We identified 11 international articles reporting research-based principles for involvement published between 2013 and 2017. We identified five 'values' and seven 'practice principles' for 'good' involvement. There was convergence between these principles and the priorities of the involvement groups. But the groups also identified additional good involvement practice that were not reported by the literature: passion, enthusiasm, informal and welcoming meeting spaces, and opportunities to share lived experiences. We present examples of how principles for good involvement are practiced in these groups, and highlight principles that have been challenging to implement.Conclusions Ongoing appraisal of public involvement is crucial. We present a process for self-evaluation, illuminate what 'good' means to researchers and public advisers involved in research, and identify areas for improvement. We conclude that provision of resources that enable support to public advisers in turn enable universities and research teams to implement other principles of good involvement.

"Are you doing your pelvic floor?" An ethnographic exploration of the interaction between women and midwives about pelvic floor muscle exercises (PFME) during pregnancy.

OBJECTIVE: Many women experience urinary incontinence (UI) during and after pregnancy. Pelvic floor muscle exercises (PFME) can prevent and reduce the symptoms of UI. The objective of the study was to explore challenges, opportunities and concerns for women and health care professionals (HCPs), related to the implementation of PFME training for women in current antenatal care. DESIGN: An ethnographic study design was used. Researchers also formed and collaborated with a public advisory group, consisting of seven women with recent experiences of pregnancy, throughout the study. PARTICIPANTS: Seventeen midwife-woman interactions were observed in antenatal clinics. In addition, 23 midwives and 15 pregnant women were interviewed. Repeat interviews were carried out with 12 of the women postnatally. Interviews were also carried out with other HCPs; four physiotherapists, a linkworker/translator and two consultant obstetricians. Additional data sources included field notes, photographs, leaflets, policy and other relevant documents. SETTING: Data were collected in three geographical areas of the UK spanning rural, urban and suburban areas. Data collection took place in antenatal clinics, in primary and secondary care settings, and the majority of women were interviewed in their homes. FINDINGS: Three broad and inter-related themes of "ideological commitment", "confidence" and "assumptions, stigma and normalisation" were identified. The challenges, opportunities and concerns regarding PFME implementation were explored within these themes. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Although HCPs and some women knew that PFME were important, they were not prioritised and the significant benefits of doing PFME may not have been communicated by midwives or recognised by women. There was a lack of confidence amongst midwives to teach PFME and manage UI within the antenatal care pathway and amongst women to ask about PFME or UI. A perceived lack of consistent guidelines and policy at local and national levels may have impeded clear communication and prioritisation of PFME. Furthermore, assumptions made by both women and midwives, for example, women regarding UI as a normal outcome of pregnancy, or midwives' perception that certain women were more likely to do PFME, may have exacerbated this situation. Training for midwives to help women in the antenatal period to engage in PFME could address challenges and concerns and to help prevent opportunities for women to learn about PFME from being missed.

Parent-to-parent support interventions for parents of babies cared for in a neonatal unit-protocol of a systematic review of qualitative and quantitative evidence.

BACKGROUND: Parents of babies admitted to neonatal units experience an arduous emotional journey. Feelings of helplessness, fear, sadness, guilt, grief and anger are common. These feelings can lead to anxiety, depression and post-traumatic stress which may persist long after discharge from the unit. Support from a parent with first-hand experience able to empathise with problems and challenges may help. This systematic review will identify quantitative and qualitative evidence to address the role of parent-to-parent support interventions for families of babies cared for in neonatal units, and combine the findings in an integrated synthesis. METHODS: We are working in collaboration with a study-specific Parent Advisory Group (PAG) of parents who have relevant and varied lived experience of having a baby in neonatal care and those who have been involved in providing peer support. With the PAG, we will carry out a systematic review bringing together all existing research on parent-to-parent support for parents of babies cared for in neonatal units. This will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The protocol has been produced in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol extension (PRISMA-P). We have co-produced a plain language protocol summary with the PAG which details the different stages of the project, and this is available via our website ( http://clahrc-peninsula.nihr.ac.uk/research/parent-to-parent-support ) for anyone interested in learning more about the detail of the project. DISCUSSION: All outputs will be available on the NIHR CLAHRC South West Peninsula (PenCLAHRC) website and promoted via PenCLAHRC networks as well as organisations that have been contacted throughout the project. PAG members will be involved in writing and reviewing the academic paper and final report and in co-producing dissemination products such as plain language summaries. The PAG will influence the main conclusions of the systematic review, aid interpretation and help to communicate results in the most appropriate ways. We will hold an impact conference with representatives from neonatal units, national neonatal networks, commissioners of services and parents to discuss what the findings mean for clinical practice and service provision.

Involving Members of the Public in Health Economics Research: Insights from Selecting Health States for Valuation to Estimate Quality-Adjusted Life-Year (QALY) Weights.

Over recent years, public involvement in health research has expanded considerably. However, public involvement in designing and conducting health economics research is seldom reported. Here we describe the development, delivery and assessment of an approach for involving people in a clearly defined piece of health economics research: selecting health states for valuation in estimating quality-adjusted life-years (QALYs). This involvement formed part of a study to develop a condition-specific preference-based measure of health-related quality of life, the Multiple Sclerosis Impact Scale (MSIS-8D), and the work reported here relates to the identification of plausible, or realistic, health states for valuation. An Expert Panel of three people with multiple sclerosis (MS) was recruited from a local involvement network, and two health economists designed an interactive task that enabled the Panel to identify health states that were implausible, or unlikely to be experienced. Following some initial confusion over terminology, which was resolved by discussion with the Panel, the task worked well and can be adapted to select health states for valuation in the development of any preference-based measure. As part of the involvement process, five themes were identified by the Panel members and the researchers which summarised our experiences of public involvement in this health economics research example: proportionality, task design, prior involvement, protectiveness and partnerships. These are described in the paper, along with their practical implications for involving members of the public in health economics research. Our experience demonstrates how members of the public and health economists can work together to improve the validity of health economics research. Plain Language Summary It has become commonplace to involve members of the public in health service research. However, published reports of involving people in designing health economics research are rare. We describe how we designed a way of involving people in a particular piece of health economics research.The aim of the work was to produce descriptions of different states of health experienced by people with multiple sclerosis (MS). These descriptions have since been rated in terms of how good or bad they are in a way that can be used by the National Institute for Health and Care Excellence (NICE) to make decisions about what services to fund on the NHS.We formed a panel of three people with MS, and designed a task to help the group produce health descriptions likely to be experienced by people with MS. After discussion about jargon, and working together to find more layman's terms, the task worked well, and can be adapted to produce health descriptions for any condition.We identified some key themes about working together that give insights into how members of the public can be involved in health economics research, and show the importance of their involvement in improving the relevance of this research.

Does funded research reflect the priorities of people living with type 1 diabetes? A secondary analysis of research questions.

OBJECTIVES: This study explored the divergence and convergence between funded research about type 1 diabetes and the research agenda of people living with the condition and their carers. DESIGN, METHOD, SETTING: A secondary analysis was undertaken of existing data from two UK organisations who regularly work with patients and carers to identify research priorities. The research ideas of people with diabetes were identified in two ways: in 15 research question generation workshops involving approximately 100 patients and carers, and in a James Lind Alliance Type 1 Diabetes Priority Setting Partnership with approximately 580 patients, carers and clinicians (clinician question submissions were excluded from analysis). A total of 859 individual research questions were collected from patients and carers. Diabetes research funding activity was identified through extensive online searches which provided a total of 172 relevant research projects for analysis. RESULTS: The data were thematically analysed and areas of priority for research identified and compared between the patient and funded research agendas. The overall finding of this study is that there is substantial convergence between the two research agendas, alongside some important areas of divergence. The key areas of divergence were found in care delivery, injection issues, psychosocial impacts and women's health. We also demonstrate how an apparently convergent priority can host significant differences in emphasis between patient-generated and funded research agendas. CONCLUSIONS: We offer a comparison of a funded research agenda with one that has been derived directly from people with type 1 diabetes without initial framing by researchers. This provided a rare opportunity to explore the viewpoints of the end-users of research and compare them to realised research as determined by researchers and research organisations.

Associations between interarm differences in blood pressure and cardiovascular disease outcomes: protocol for an individual patient data meta-analysis and development of a prognostic algorithm.

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

Development and testing of a medline search filter for identifying patient and public involvement in health 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.

Motivators for uptake and maintenance of exercise: perceptions of long-term stroke survivors and implications for design of exercise programmes.

PURPOSE: Exercise-after-stroke programmes are increasingly being provided to encourage more physical exercise among stroke survivors, but little is known about what motivates people with stroke to participate in them. This research aimed to identify factors that motivate long-term stroke survivors to exercise, and the implications for programme design. METHODS: In two separate studies, focus groups and individual interviews were used to investigate the views of long-term stroke survivors on exercise and participating in exercise programmes. Their data were analysed thematically, and the findings of the studies were synthesised. RESULTS: Eleven stroke survivors and two partners took part in two focus groups; six other stroke survivors (one with a partner) were interviewed individually. Factors reported to influence motivation were the psychological benefits of exercise, a desire to move away from a medicalised approach to exercise, beliefs about stroke recovery, and on-going support to sustain commitment. A number of potential implications of these themes for exercise programme design were identified. CONCLUSIONS: A range of personal beliefs and attitudes and external factors may affect the motivation to exercise, and these vary between individuals. Addressing these factors in the design of exercise programmes for long-term stroke survivors may enhance their appeal and so encourage greater engagement in exercise. IMPLICATIONS FOR REHABILITATION: Exercise programmes may be more attractive to long-term stroke survivors if the psychological well-being benefits of participation are emphasised in their promotion. Some participants will be more attracted by programmes that are de-medicalised, for example, by being located away from clinical settings, and led by or involving suitably-trained non-clinicians. Programmes offered in different formats may attract stroke survivors with different beliefs about the value of exercise in stroke recovery. Programmes should provide explicit support strategies for on-going engagement in exercise.
