Health economic evaluation evidence of interventions for peripartum depression: a scoping review

This scoping review provides a broad overview of the existing literature on economic evaluations of preventive, screening, and treatment programmes for peripartum depression (PPD). PPD is one of the leading causes of disease-related disability among women. However, PPD often goes undiagnosed and untreated, with as many as half of cases not being identified. We followed the PICO-P (publication type) structure. Databases were searched from inception until 30 June 2023. The intervention stage in the studies was classified as prevention, screening, treatment, screening and treatment, and prevention and treatment. The health economics methods of the studies were divided into cost-effectiveness analysis, cost-utility analysis, cost-benefit analysis, cost-minimisation analysis, return of investment, and multiple. Ultimately, 38 studies were included for extraction and evaluation. Several interventions for PPD may be cost effective, including peer support, psychological therapies, and screening strategies using tools like the Edinburgh Postnatal Depression Scale (EPDS). However, study limitations include heterogeneity across studies, methodological limitations, and limited generalisability to diverse populations. The cost-effectiveness results of PPD interventions may differ across different health systems, partly due to differences in the amount and distribution of resources available. By implementing suggested policy recommendations, policymakers can significantly improve the identification, treatment, and prevention of PPD, ultimately improving the health and well-being of mothers, children, and families.
