Prenatal care utilization in Minnesota. Patterns of concern, areas for improvement.

We conducted an analysis of prenatal care utilization among Minnesota resident mothers for the years 1990 to 1991 to determine why this state ranks poorly in prenatal care use while its infant mortality rate is one of the lowest in the nation. We found that 6% of women began care in the first trimester yet did not receive an adequate number of visits. These women were more likely to deliver preterm, low birthweight infants than women who started care later. Fifteen percent of women had records missing important data, and these women also had higher rates of poor pregnancy outcomes. Our findings have implications for maternal outreach and follow-up efforts and suggest potential benefits from private and public health collaborations. In addition, efforts to improve the quality of data reporting should begin immediately.
