The Adequacy of Prenatal Care Utilization Index (also known as the Kotelchuck Index) classifies prenatal care received by mothers into 1 of 4 categories: inadequate, intermediate, adequate, and adequate plus by combining information about the timing of prenatal care, the number of visits and the infant’s gestational age.  According to the Kotelchuck Index, 74.1 percent of mothers received adequate or adequate plus prenatal care, while 11.9 percent of mothers received inadequate prenatal care in 2000.
