Modifies the pregnancy-associated mortality review board

HB 3269 updates Missouri's Pregnancy-Associated Mortality Review Board to improve data collection and analysis of maternal deaths. The bill expands the board to 22 members with mandatory diversity requirements, including representation from each congressional district and across racial, ethnic, and rural/urban groups. It requires the board to review all maternal deaths (defined as deaths during pregnancy or within one year postpartum, regardless of cause), identify factors like racial disparities and "maternity care deserts" (counties lacking adequate maternity services), and collect specific data on prenatal/postnatal care. The board must produce annual reports with disaggregated data by race, ethnicity, and location, and share recommendations to reduce maternal mortality with policymakers and the public.
