Cocreators' experiences and effectiveness of cocreated interventions in improving health behaviours of adults with non-communicable diseases: a systematic review protocol

IntroductionImproved health behaviours and help-seeking behaviour reduce morbidity and mortality from non-communicable diseases (NCDs). Compliance with the recommendations of lifestyle changes for the management of NCDs has been challenging, as patients find it difficult to change and sustain lifestyle behaviours for a long period of time. Studies have reported that cocreated interventions are promising in addressing negative health behaviours and improving health outcomes in people with NCDs; however, no conclusive evidence exists. Therefore, this review aims to evaluate cocreators' experiences and the effectiveness of cocreated interventions in improving the health behaviours of individuals with NCDs.Methods and analysisThis review will follow the recommendations described in the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline and the Enhancing Transparency in Reporting the Synthesis of Qualitative Research statement for the synthesis of qualitative data. The following databases: Co-creation Database (https://zenodo.org/record/6773028%23.Y9h2sezP1pg), MEDLINE (via OVID), Cumulative Index to Nursing and Allied Health Literature (via EBSCO Host), EMBASE (via OVID), PsycINFO (via OVID), Scopus, Web of Science, Cochrane Library and grey literature will be searched. The identified studies will be independently screened by two reviewers to determine their eligibility. The review will target to include studies that investigated the experiences of cocreators and/or the effectiveness of cocreated interventions on the health behaviour and/or health outcomes of adults with NCDs. Two independent reviewers will also appraise the quality of the included studies, as well as data extraction. A narrative synthesis will be used to summarise the findings. Thematic synthesis and meta-analysis will be conducted for the qualitative and quantitative data, respectively. The qualitative and quantitative findings will be integrated using the parallel result convergent synthesis.Ethics and disseminationEthics approval is not applicable because the review will only use data from the published studies. The findings will be disseminated through publication in peer-reviewed journals and conference presentations.PROSPERO registration numberCRD42023391746.
