title: Medicaid managed care in Chicago: changes in utilization.
abstract: In 1993, Illinois implemented Healthy Moms/Healthy Kids (HM/HK) in Chicago, a Medicaid managed care program for pregnant women and children. This study examines changes in immunizations for children (n = 134,072), prenatal care use for pregnant women (n = 5,151), and inpatient stays for mothers (n = 5,151) and newborns (n = 2,699) under the HM/HK program as compared with fee-for-service Medicaid in 1992 and 1993. HM/HK children were 10 percent more likely to receive any immunizations, and HM/HK pregnant women were 13 percent more likely to receive some prenatal care. Mothers' inpatient stays at delivery did not change under HM/HK. The length of newborn stays fell between 1992 and 1993, with both the HM/HK and the Medicaid 1993 comparison group deliveries associated with statistically shorter stays. During the early months of the program, improvements in the quantity of expected preventive care received were evident among children and women.
