Protocol for a systematic review of economic evaluations conducted on gender-transformative interventions aimed at preventing unintended pregnancy and promoting sexual health in adolescents

INTRODUCTION: In the context of family planning and reproductive health, a gender-transformative approach involves helping communities understand and challenge the social norms that perpetuate inequalities between men and women, and improving women’s access to key services. The purpose of this systematic review is to synthesise the best available evidence on economic evaluations of gender transformative interventions targeted at preventing unintended pregnancy and promoting sexual health in adolescents, assess the methodological quality of the economic evaluation studies and identify gaps in the evidence. METHODS AND ANALYSIS: We will search the following bibliographic databases for economic evaluations that meet our selection criteria; PubMed, Cochrane, National Health Service EE database, SCOPUS, CINHAL, Web of Science and Paediatric EE Database. We will additionally conduct a grey literature search. The search will be conducted for the period 1 January 1990 to 31 December 2021. Two independent reviewers will conduct the screening, data extraction and quality assessment. We will consider the following outcomes from economic evaluations; relative resource use, cost and incremental cost-effectiveness ratio, incremental net benefit ratio or net present value, quality-adjusted life-years and disability-adjusted life-years. Quality assessment will be conducted using the Consolidated Health Economic Evaluation Reporting Standards statement and the Consensus on Health Economic Criteria checklist. Results will be reported using summary tables and narratively. Attempts will be made to use the Joanna Briggs Institute three-by-three dominance ranking matrix tool to compare relevant cost-effectiveness studies. ETHICS AND DISSEMINATION: Ethics approval is not required because the review will not use individual patient data, instead publicly available economic evaluation research studies will be used. However, an ethics exemption was obtained from the Stellenbosch University Health Research Ethics Committee, Reference No: X21/05/012. The results of the systematic review will be published in a peer-reviewed journal and presented at a relevant scientific conference. PROSPERO REGISTRATION NUMBER: CRD42021264698.
