Abstract

Purpose: Impacting 1 in 1000 women, untreated postpartum psychosis is associated with a 4% infanticide rate. This systematic review aims to identify factors that are associated with infanticide resulting from psychosis in the puerperal period and pinpoint areas of missed opportunity for intervention. Methods: A systematic literature review was conducted in accordance with PRISMA guidelines to identify and synthesize cases of maternal infanticide among perinatal females with evidence of postpartum psychosis. Four independent reviewers screened 231 articles identified in searches of three databases (PsycInfo, PubMed, and Web of Science) for studies conducted from 2013 to 2023. Results: Twelve studies were included in the final review. Findings indicate that those experiencing puerperal psychosis have increased incidence of infanticide suggesting missed opportunities for intervention and treatment. Common factors in mothers who committed infanticide as a result of delusions and/or hallucinations associated with PMADs were identified, including lack of standardized screening tools, preference for traditional and/or cultural healing practices, and access to care. Conclusion: The current body of evidence supports developing and evaluating clinical interventions aimed at improving maternal mental health outcomes and infant outcomes in perinatal women experiencing puerperal psychosis.
