Medicaid home visitation and maternal and infant healthcare utilization.
BACKGROUND
The Michigan Maternal and Infant Health Program (MIHP) is a population-based home-visitation program providing care coordination, referrals, and visits based on a plan of care. MIHP is available to all Medicaid-eligible pregnant women and infants aged ≤1 year in Michigan.


OBJECTIVE
To assess the effects of MIHP participation on maternal and infant healthcare utilization.


METHODS
Propensity-score matching methods were used to assess differences in healthcare utilization between MIHP participants and nonparticipants using 2009-2010 Medicaid claims and administrative data obtained from the Michigan Department of Community Health. Data were analyzed between October 2011 and March 2013.


RESULTS
MIHP participants had higher odds of receiving any prenatal care compared to matched women not participating in MIHP (OR=2.94, 95% CI=2.43, 3.60) and higher odds of receiving adequate prenatal care (OR=1.06, 95% CI=1.01, 1.11). MIHP participants had higher odds of receiving an appropriately timed postnatal visit (OR=1.50, 95% CI=1.43, 1.57). Infants participating in MIHP had higher odds of receiving any well-child visits over the first year of life (OR=1.70, 95% CI=1.51, 1.93) and higher odds of receiving the appropriate number of well-child visits over their first year of life (OR=1.47, 95% CI=1.35, 1.60) compared to matched nonparticipant infants.


CONCLUSIONS
The results from Michigan provide strong evidence for the effectiveness of a Medicaid-sponsored population-based home-visitation program in improving maternal prenatal and postnatal care and infant care. This evidence is important to consider as the federal healthcare reform is implemented and states are making decisions on the expansion of the Medicaid program.
