Introduction: Hand osteoarthritis (OA) is a common joint disorder in the adult population. No cure for hand OA is known yet, but treatment aims to reduce symptoms. Non-surgical and non-pharmacological therapy interventions can include splinting, patient education, and strengthening and range of movement exercises. However, it is still unclear which treatment is most beneficial for which patient. This study aims to identify subgroups of patients with hand OA that benefit most from the different non-surgical and non-pharmacological treatments., Methods and Analysis: We will conduct an individual patient data (IPD) meta-analysis by extracting IPD of eligible published randomised controlled trials (RCTs). A systematic literature search through Embase, Medline and Cochrane was performed on 8 February 2021. The primary outcome will be hand pain, and our secondary outcomes are objective and subjective hand physical functions. Subgroups include age, sex, body mass index, hypermobility and other comorbidities, pain medication, occupation, baseline pain, erosive OA, type and the number of hand joints involved, radiological severity of OA, and duration of symptoms. IPD of RCTs with homogeneous treatment interventions will be pooled and analysed using a two-stage approach to evaluate treatment effect on different subgroups., Ethics and Dissemination: No new data will be collected, so research ethical or governance approval is exempt. Findings will be disseminated via national and international conferences, publications in peer-reviewed journals, and summaries posted on websites accessed by the public and clinicians., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: Brace effectiveness for knee osteoarthritis (OA) remains unclear and international guidelines offer conflicting recommendations. Our trial will determine the clinical and cost-effectiveness of adding knee bracing (matched to patients' clinical and radiographic presentation and with adherence support) to a package of advice, written information and exercise instruction delivered by physiotherapists., Methods and Analysis: A multicentre, pragmatic, two-parallel group, single-blind, superiority, randomised controlled trial with internal pilot and nested qualitative study. 434 eligible participants with symptomatic knee OA identified from general practice, physiotherapy referrals and self-referral will be randomised 1:1 to advice, written information and exercise instruction and knee brace versus advice, written information and exercise instruction alone. The primary analysis will be intention-to-treat comparing treatment arms on the primary outcome (Knee Osteoarthritis Outcomes Score (KOOS)-5) (composite knee score) at the primary endpoint (6 months) adjusted for prespecified covariates. Secondary analysis of KOOS subscales (pain, other symptoms, activities of daily living, function in sport and recreation, knee-related quality of life), self-reported pain, instability (buckling), treatment response, physical activity, social participation, self-efficacy and treatment acceptability will occur at 3, 6, and 12 months postrandomisation. Analysis of covariance and logistic regression will model continuous and dichotomous outcomes, respectively. Treatment effect estimates will be presented as mean differences or ORs with 95% CIs. Economic evaluation will estimate cost-effectiveness. Semistructured interviews to explore acceptability and experiences of trial interventions will be conducted with participants and physiotherapists delivering interventions., Ethics and Dissemination: North West Preston Research Ethics Committee, the Health Research Authority and Health and Care Research in Wales approved the study (REC Reference: 19/NW/0183; IRAS Reference: 247370). This protocol has been coproduced with stakeholders including patients and public. Findings will be disseminated to patients and a range of stakeholders., Trial Registration Number: ISRCTN28555470., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Objective: Physiotherapists commonly provide non-surgical care for people with knee osteoarthritis (OA). It is unknown if patients are receiving high-quality physiotherapy care for their knee OA. This study aimed to explore the experiences of people who had recently received physiotherapy care for their knee OA in Australia and how these experiences aligned with the national Clinical Care Standard for knee OA., Design: Qualitative study using semistructured individual telephone interviews and thematic analysis, where themes/subthemes were inductively derived. Questions were informed by seven quality statements of the OA of the Knee Clinical Care Standard. Interview data were also deductively analysed according to the Standard., Setting: Participants were recruited from around Australia via Facebook and our research volunteer database., Participants: Interviews were conducted with 24 people with recent experience receiving physiotherapy care for their knee OA. They were required to be aged 45 years or above, had activity-related knee pain and any knee-related morning stiffness lasted no longer than 30 min. Participants were excluded if they had self-reported inflammatory arthritis and/or had undergone knee replacement surgery for the affected knee., Results: Six themes emerged: (1) presented with a pre-existing OA diagnosis (prior OA care from other health professionals; perception of adequate OA knowledge); (2) wide variation in access and provision of physiotherapy care (referral pathways; funding models; individual vs group sessions); (3) seeking physiotherapy care for pain and functional limitations (knee symptoms; functional problems); (4) physiotherapy management focused on function and exercise (assessment of function; various types of exercises prescribed; surgery, medications and injections are for doctors; adjunctive treatments); (5) professional and personalised care (trust and/or confidence; personalised care) and (6) physiotherapy to postpone or prepare for surgery., Conclusion: Patients' experiences with receiving physiotherapy care for their knee OA were partly aligned with the standard, particularly regarding comprehensive assessment, self-management, and exercise., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Introduction: There is a significant treatment gap, with only a few community-based services for people with schizophrenia in low-income and middle-income countries. Poor treatment adherence in schizophrenia is associated with poorer health outcomes, suicide attempts and death. We previously reported the effectiveness of supervised treatment in outpatients for schizophrenia (STOPS) for improving treatment adherence in patients with schizophrenia. However, STOPS was evaluated in a tertiary care setting with no primary care involvement, limiting its generalisability to the wider at-risk population. We aim to evaluate the effectiveness of STOPS+ in scaling up the primary care treatment of schizophrenia to a real-world setting., Methods and Analysis: The effectiveness of the STOPS+ intervention in improving the level of functioning and medication adherence in patients with schizophrenia in Pakistan will be evaluated using a cluster randomised controlled trial design. We aim to recruit 526 participants from 24 primary healthcare centres randomly allocated in 1:1 ratio to STOPS+ intervention and enhanced treatment as usual arms. Participants will be followed-up for 12 months postrecruitment. The sample size is estimated for two outcomes (1) the primary clinical outcome is level of functioning, measured using the Global Assessment of Functioning scale and (2) the primary process outcome is adherence to treatment regimen measured using a validated measure. An intention-to-treat approach will be used for the primary analysis., Ethics and Dissemination: Ethical approval has been obtained from Keele University Ethical Review Panel (ref: MH-190017) and Khyber Medical University Ethical Review Board (ref: DIR-KMU-EB/ST/000648). The results of the STOPS+ trial will be reported in peer-reviewed journals and academic conferences and disseminated to local stakeholders and policymakers., Trial Registration Number: ISRCTN93243890., Competing Interests: Competing interests: SF in the past 3 years has received honoraria and speaker’s fees from Otsuka, Lundbeck and Sunovian pharma and also research funding from Sunovian Pharmaceutical. MU-H and MFK received funding from different pharmaceuticals to attend scientific meetings., (© Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY. Published by BMJ.)

Introduction: The economic cost of osteoarthritis (OA) is high. At least 4.4 million people have hand OA in the UK. Symptomatic thumb base OA affects 20% of people over 55 years, causing more pain, work and functional disability than OA elsewhere in the hand. Most evidence-based guidelines recommend splinting for hand OA. Splints that support or immobilise the thumb base are routinely used despite there being limited evidence on their effectiveness. The potential effects of placebo interventions in OA are acknowledged, but few studies investigate the clinical efficacy of rehabilitation interventions nor the impact of any placebo effects associated with splints., Methods and Analysis: Participants aged 30 years and over with symptomatic thumb base OA will be recruited into the trial from secondary care occupational therapy and physiotherapy centres. Following informed consent, participants will complete a baseline questionnaire and then be randomised into one of three treatment arms: a self-management programme, a self-management programme plus a verum thumb splint or a self-management programme plus a placebo thumb splint. The primary outcome is the Australian Canadian Osteoarthritis Hand Index (AUSCAN) hand pain scale. The study endpoint is 8 weeks after baseline. Baseline assessments will be carried out prior to randomisation and outcomes collected at 4, 8 and 12 weeks. Cost-effectiveness analysis will be conducted and individual qualitative interviews conducted with up to 40 participants after 8 weeks to explore perceptions and outcome expectations of verum and placebo splints and exercise., Ethics and Dissemination: South Central-Oxford C Research Ethics Committee approved this study (16/SC/0188). The findings will be disseminated to health professional conferences, journals and lay publications for patient organisations. The research will contribute to improving the management of thumb base OA and help clinicians and patients make informed decisions about the value of different interventions., Trial Registration Number: ISRCTN54744256., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Introduction: Worldwide, 10%-20% of children and adolescents experience mental health conditions. However, most such disorders remain undiagnosed until adolescence or adulthood. Little is known about the factors that influence mental health in children and adolescents, especially in low and middle-income countries (LMIC), where environmental threats, such as poverty and war, may affect optimal neurodevelopment. Cohort studies provide important information on risks and resilience across the life course by enabling tracking of the effects of early life environment on health during childhood and beyond. Large birth cohort studies, including twin cohorts that can be aetiologically informative, have been conducted within high-income countries but are not generalisable to LMIC. There are limited longitudinal birth cohort studies in LMIC., Methods: We sought to enhance the volume of impactful research in Sri Lanka by establishing a Centre of Excellence for cohort studies. The aim is to establish a register of infant, child and adolescent twins, including mothers pregnant with twins, starting in the districts of Colombo (Western Province) and Vavuniya (Northern Province). We will gain consent from twins or parents for future research projects. This register will provide the platform to investigate the aetiology of mental illness and the impact of challenges to early brain development on future mental health. Using this register, we will be able to conduct research that will (1) expand existing research capacity on child and adolescent mental health and twin methods; (2) further consolidate existing partnerships and (3) establish new collaborations. The initiative is underpinned by three pillars: high-quality research, ethics, and patient and public involvement and engagement (PPIE)., Ethics and Dissemination: Ethical approval for this study was obtained from the Ethics Review Committee of Sri Lanka Medical Association and Keele University's Ethical Review Panel. In addition to journal publications, a range of PPIE activities have been conducted., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Introduction: Knee and hip osteoarthritis (OA) is a leading cause of disability worldwide. Therapeutic exercise is a recommended core treatment for people with knee and hip OA, however, the observed effect sizes for reducing pain and improving physical function are small to moderate. This may be due to insufficient targeting of exercise to subgroups of people who are most likely to respond and/or suboptimal content of exercise programmes. This study aims to identify: (1) subgroups of people with knee and hip OA that do/do not respond to therapeutic exercise and to different types of exercise and (2) mediators of the effect of therapeutic exercise for reducing pain and improving physical function. This will enable optimal targeting and refining the content of future exercise interventions., Methods and Analysis: Systematic review and individual participant data meta-analyses. A previous comprehensive systematic review will be updated to identify randomised controlled trials that compare the effects of therapeutic exercise for people with knee and hip OA on pain and physical function to a non-exercise control. Lead authors of eligible trials will be invited to share individual participant data. Trial-level and participant-level characteristics (for baseline variables and outcomes) of included studies will be summarised. Meta-analyses will use a two-stage approach, where effect estimates are obtained for each trial and then synthesised using a random effects model (to account for heterogeneity). All analyses will be on an intention-to-treat principle and all summary meta-analysis estimates will be reported as standardised mean differences with 95% CI., Ethics and Dissemination: Research ethical or governance approval is exempt as no new data are being collected and no identifiable participant information will be shared. Findings will be disseminated via national and international conferences, publication in peer-reviewed journals and summaries posted on websites accessed by the public and clinicians., Prospero Registration Number: CRD42017054049., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Objective: To identify, summarise and synthesise available literature on the effectiveness of implementation strategies for optimising implementation of complex interventions in primary care., Design: Systematic review of reviews., Data Sources: MEDLINE, EMBASE, CINAHL, Cochrane Library and PsychINFO were searched, from first publication until December 2013; the bibliographies of relevant articles were screened for additional reports., Eligibility Criteria for Selecting Studies: Eligible reviews had to (1) examine effectiveness of single or multifaceted implementation strategies, (2) measure health professional practice or process outcomes and (3) include studies from predominantly primary care in developed countries. Two reviewers independently screened titles/abstracts and full-text articles of potentially eligible reviews for inclusion., Data Synthesis: Extracted data were synthesised using a narrative approach., Results: 91 reviews were included. The most commonly evaluated strategies were those targeted at the level of individual professionals, rather than those targeting organisations or context. These strategies (eg, audit and feedback, educational meetings, educational outreach, reminders) on their own demonstrated a small to modest improvement (2-9%) in professional practice or behaviour with considerable variability in the observed effects. The effects of multifaceted strategies targeted at professionals were mixed and not necessarily more effective than single strategies alone. There was relatively little review evidence on implementation strategies at the levels of organisation and wider context. Evidence on cost-effectiveness was limited and data on costs of different strategies were scarce and/or of low quality., Conclusions: There is a substantial literature on implementation strategies aimed at changing professional practices or behaviour. It remains unclear which implementation strategies are more likely to be effective than others and under what conditions. Future research should focus on identifying and assessing the effectiveness of strategies targeted at the wider context and organisational levels and examining the costs and cost-effectiveness of implementation strategies., Prospero Registration Number: CRD42014009410., (Published by the BMJ Publishing Group Limited.
