Role of Doulas in Improving Maternal Health and Health Equity Among Medicaid Enrollees, 2014‒2023.

Objectives. To assess the relationship between doula utilization and health outcomes of females enrolled in Medicaid-affiliated plans in the United States. Methods. In this retrospective, observational cohort study, we used Medicaid claims data from a national health insurer to compare health outcomes between females who used and who did not use a doula (2014-2023). We conducted propensity score matching using a 1:1 case‒control match, without replacement, and fit logistic regressions to analyze the relative risks for maternal health outcomes. Results. The study population included 722 matched pairs with and without a doula. Results indicate females with doulas had a 47% lower risk of cesarean delivery and a 29% lower risk of preterm birth, and were 46% more likely to attend a postpartum checkup (all differences P < .05). Conclusions. Doula care is associated with improved health outcomes among Medicaid enrollees. Public Health Implications. Doulas have garnered increasing interest from policymakers as a strategy to address increasing trends in maternal morbidity and persistent health disparities. This study provides evidence from Medicaid enrollees across the United States that doula care can improve maternal health.
