Factors affecting the implementation of task-sharing interventions for perinatal depression in low- and middle-income countries: A systematic review and qualitative metasynthesis.

Background The vast majority of women with perinatal depression (PND) live in low- and middle-income countries (LMICs). Task sharing is an alternative delivery strategy to implement PND services. However, the exploration of influencing factors for task sharing in PND services is poor. Therefore, this study aimed to identify factors affecting LMICs to implement PND task-sharing interventions from the perspective of stakeholders and weigh their levels of evidence. Methods A comprehensive literature search was carried out through six English and Chinese databases on qualitative data. We used Critical Appraisal Skills Programme (CASP)/Meta Quality Appraisal Tool (MetaQAT) to appraise included studies, extracted data according to the Consolidated Framework for Implementation Research (CFIR), and assigned levels of confidence in the factors through Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual). Results 17 studies met the eligibility criteria, factors identified with high levels of evidence were coded to the CFIR constructs, including "Knowledge and Attitudes of Those Served by the Organization", "Available Resources", "Compatibility", "Access to knowledge and information", "Resources of Those Served by the Organization" and "Alignment". Conclusion This metasynthesis highlights task sharing in PND interventions is influenced by multiple factors. We synthesized and developed implementation recommendations for practice. Strategies must be actively developed to enable women and their families to enjoy the benefits of good perinatal mental health.
