Global contribution of suicide to maternal mortality: a systematic review protocol.

Maternal suicide is a significant contributor to maternal mortality with devastating consequences for women, families and society. Maternal mortality reporting systems differ across countries and there is no up-to-date overview of maternal suicide deaths globally. This systematic review aims to synthesise the evidence on maternal suicide. The primary objective is to determine the contribution of suicide towards maternal mortality globally and explore differences between geographical regions. The secondary objectives are to summarise the availability and quality of data globally and to describe how suicide deaths are classified across different countries. This protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. Medline, Embase, PsycINFO, Global Health and CINAHL databases and the grey literature were searched with no date or language restrictions. Observational studies, national surveys and reports that present data on maternal deaths due to suicide occurring during pregnancy, intrapartum and in the postpartum period will be included. Screening, data extraction and quality assessment will be conducted independently by two reviewers. Results will be summarised narratively. If sufficient outcome data are available, random-effects meta-analyses will be conducted to determine global pooled estimates of suicide-related maternal mortality rates and the proportion of maternal deaths attributable to suicide. Ethical approval is not required for this systematic review. Results will be written up for publication in a peer-reviewed journal and findings will be shared at national and international conferences. CRD42023429072.
