YR 2025 UL http://www.jabfm.org/content/early/2025/07/30/jabfm.2024.240302R2.abstract AB Introduction: This study evaluates participation in Wisconsin Medicaid’s Prenatal Care Coordination (PNCC) program and its association with children’s well-child visit (WCV) receipt.Study Design: Data came from linked Wisconsin birth records (2011 to 2015) and Medicaid claims and enrollment data (2010 to 2019). The sample comprised 113,347 children with Medicaid-paid births and continuous Medicaid enrollment ranging from 12 to 48 months post-birth. A sibling subsample comprised of 35,373 children. PNCC receipt in pregnancy was measured dichotomously (none; any) and categorically (none; assessment/care plan only; service uptake). Any WCV receipt and recommended WCV receipt (which varied by age) were measured during each year from age 0 up to 4 years old. Conventional logistic regressions and sibling fixed effects (FE) regressions estimated associations between PNCC receipt and WCV receipt.Results: Demographic-adjusted sibling FE regressions—which best control for unobserved confounding—indicated that any PNCC was positively associated with children receiving any WCVs at age 0 to <1 year-old (OR 1.48; 95% CI 1.05–2.08) and at age 1 to <2 years old (OR 1.24; 95% CI 1.03–1.50). In addition, adjusted sibling FE regressions found that PNCC service uptake was associated with children receiving the recommended number of WCVs at age 0 to <1 year-old (OR 1.35; 95% CI 1.18–1.55).Conclusions: PNCC may improve children’s WCV attendance in the first 2 years of life. Findings underscore the potential for obstetric care coordination programs to enhance the continuity of preventive care for participating families.
