Community-based interventions to prevent stroke in low-income and middle-income countries: a protocol for a systematic review and meta-analysis

Abstract

IntroductionStroke is the second leading cause of death and morbidity across the globe. In low-income and middle-income countries (LMICs), it has become an overwhelming burden over the past few decades. This burden is escalating at a much greater pace compared with that of high-income countries. It is considered the most frequent cause of adult disability that affects the quality of life. ‘Prevention’ is one of the key components to combating stroke. In this regard, community-based interventions can play a vital role in improving population-level health and well-being. Considering the escalating trend of stroke in LMICs, this systematic review aims to map the available community-based interventions in preventing stroke and to conduct further analysis regarding the effectiveness of the identified interventions.Methods and analysisWe have searched Medline, Web of Science and Scopus using a comprehensive search strategy in October 2021. Two reviewers will independently perform screening, data extraction and risk of bias (ROB) assessment. The ROB assessment and applicability of results of eligible studies will be performed using the Cochrane ROB tool for assessing randomised controlled trials and the ROBANS (Risk Of Bias Assessment tool for Non-randomised Studies) to assess non-randomised studies. A random-effect model meta-analysis will be used to calculate pooled results and to obtain weighted OR and risk ratio of incidence of stroke along with corresponding 95% CI.Ethics and disseminationThe results will be disseminated through publishing in a peer-reviewed journal and public presentations at relevant national and international conferences. Ethical approval is not required as this is a systematic review of publicly available data.PROSPERO registration numberCRD42021283670.
