The Maternal Infant Health Program (MIHP), a population-based home visiting program targeting all Medicaid-eligible pregnant women and infants up to age one, is the largest program dedicated to serving Medicaid pregnant women and children in the state. MIHP provides support to promote healthy pregnancies, positive birth outcomes, and healthy infants. In 2011 we proposed to the Michigan Department of Community Health a research plan for an evidence-based evaluation of MIHP effectiveness in promoting healthy pregnancies, positive birth outcomes, and healthy infants. A randomized trial was not feasible as Medicaid is an entitlement program and all insured pregnant women were eligible for MIHP. As a result, the research team proposed a quasi-experimental evaluation of the program. The objective of this study was to provide a quasi-experimental evaluation of MIHP effectiveness. The central hypothesis was that Medicaid-eligible pregnant women and infants enrolled in MIHP have better pregnancy, birth, and post-birth health outcomes than women and infants not enrolled in the program. Using data on the entire Michigan population of Medicaid-eligible pregnant women and infants we tested the hypothesis by comparing outcomes between MIHP participants and non-participants using a matched-group research design.
The MIHP Quasi-Experimental Evaluation program of research is ongoing. A first summary report is available. Peer-reviewed manuscripts were published in the American Journal of Preventive Medicine and in JAMA Pediatrics.
The continuation of this work is being directed by the Department of Obstetrics and Gynecology. For more information, contact LeeAnne Roman, MSN, PhD - Co - Primary Investigator.
