OP66 Effect of pedometer-based walking interventions on long-term health outcomes: prospective 4-year follow-up of 2 randomised controlled trials using routine primary care data

Introduction: The use of link workers for social prescribing and health and social care coordination is increasing, but there is insufficient data to demonstrate their effectiveness or for whom they work best. Multimorbidity is increasing in prevalence and affects those living in deprived areas ten years earlier than affluent areas. This systematic review aims to examine the evidence for the effectiveness and costs of link workers in improving health outcomes. We will also look for evidence for the use of link workers specifically for people living with multimorbidity and in deprived areas. Methods: Databases of published and grey literature will be searched for randomised and non-randomised controlled trials examining use of link workers based in primary care for community dwelling adults compared to usual care. Primary outcomes will be health related quality of life and mental health. Data on costs will be extracted. Studies will be selected for inclusion by title and abstract review by two reviewers. A Preferred Reporting Items for Systematic Reviews (PRISMA) flow diagram will document the selection process. A standardised form will be used to extract data. Data quality will be assessed using the Cochrane Risk of Bias tool for randomised controlled trials, a narrative synthesis will be completed and the GRADE assessment tool used to comment on evidence quality. A meta-analysis of effect size of primary outcomes and subgroup analysis for multimorbidity and social deprivation will be performed if there are sufficient comparable data. Conclusion: This systematic review will give an important overview of the evidence for the use of link workers providing social prescribing and health and social care coordination in primary care. This will help inform intervention development and guide policy makers on whether these interventions are cost effective and which groups stand to benefit most.

Background In most trials and systematic reviews that evaluate exercise-based interventions in reducing depressive symptoms, it is difficult to separate treatment from prevention. Aims To evaluate the effectiveness of exercise-based interventions in reducing depressive symptoms in people without clinical depression. Method We searched PubMed, PsycINFO, Embase, WOS, SPORTDiscus, CENTRAL, OpenGrey and other sources up to 25 May 2020. We selected randomised controlled trials (RCTs) that compared exclusively exercise-based interventions with control groups, enrolling participants without clinical depression, as measured using validated instruments, and whose outcome was reduction of depressive symptoms and/or incidence of new cases of people with depression. Pooled standardised mean differences (SMDs) were calculated using random-effect models (registration at PROSPERO: CRD42017055726). Results A total of 14 RCTs (18 comparisons) evaluated 1737 adults without clinical depression from eight countries and four continents. The pooled SMD was −0.34 (95% CI −0.51 to −0.17; P < 0.001) and sensitivity analyses confirmed the robustness of this result. We found no statistical evidence of publication bias and heterogeneity was moderate (I2 = 54%; 95% CI 22–73%). Only two RCTs had an overall low risk of bias and three had long-term follow-up. Multivariate meta-regression found that a larger sample size, country (Asia) and selective prevention (i.e. people exposed to risk factors for depression) were associated with lower effectiveness, although only sample size remained significant when adjustment for multiple tests was considered. According to the Grading of Recommendations Assessment, Development and Evaluation tool, the quality of evidence was low. Conclusions Exercise-based interventions have a small effect on the reduction of depressive symptoms in people without clinical depression. It could be an alternative to or complement psychological programmes, although further higher-quality trials with larger samples and long-term follow-up are needed.

IntroductionLate preterm prelabour rupture of membranes (PROM between 34+0 and 36+6 weeks gestational age) is an important clinical dilemma. Previously, two large Dutch randomised controlled trials (RCTs) compared induction of labour (IoL) to expectant management (EM). Both trials showed that early delivery does not reduce the risk of neonatal sepsis as compared with EM, although prematurity-related risks might increase. An extensive, structured long-term follow-up of these children has never been performed.Methods and analysisThe PPROMEXIL Follow-up trial (NL6623 (NTR6953)) aims to assess long-term childhood outcomes of the PPROMEXIL (ISRCTN29313500) and PPROMEXIL-2 trial (ISRCTN05689407), two multicentre RCTs using the same protocol, conducted between 2007 and 2010 evaluating IoL versus EM in women with late preterm PROM. The PPROMEXIL Follow-up will analyse children of mothers with a singleton pregnancy (PPROMEXIL trial n=520, PPROMEXIL-2 trial n=191, total IoL n=359; total EM n=352). At 10–12 years of age all surviving children will be invited for a neurodevelopmental assessment using the Wechsler Intelligence Scale for Children-V, Color-Word Interference Test and the Movement Assessment Battery for Children-2. Parents will be asked to fill out questionnaires assessing behaviour, motor function, sensory processing, respiratory problems, general health and need for healthcare services. Teachers will fill out the Teacher Report Form and answer questions regarding school attainment. For all tests means with SDs will be compared, as well as predefined cut-off scores for abnormal outcome. Sensitivity analyses consisting of different imputation techniques will be used to deal with lost to follow-up.Ethics and disseminationThe study has been granted approval by the Medical Centre Amsterdam (MEC) of the AmsterdamUMC (MEC2016_217). Results will be disseminated through peer-reviewed journals and summaries shared with stakeholders. This protocol is published before analysis of the results.Trial registration numberNL6623 (NTR6953).
