Impact of a Mandatory Medicaid Case Management Program on Prenatal Care and Birth Outcomes

Abstract

This study examined the impact of Philadelphia's mandatory Medicaid case management program (HealthPASS) on adequacy of prenatal care and birth outcomes among enrollees. A sample of 217 deliveries for HealthPASS patients at the Hospital of the University of Pennsylvania (HUP) during 1988 was compared with a matched sample of 1988 deliveries at HUP for whom the payor was Pennsylvania's traditional fee-for-service Medicaid program. Inpatient charts for all 434 subjects were abstracted for information on sociodemographic characteristics, substance use during pregnancy (cigarettes, alcohol, and drugs), course and extent of prenatal care, and birth outcomes including birth weight, gestational age, and mortality. No significant differences were detected between the HealthPASS and Medicaid groups, suggesting that the mandatory managed care program neither improved nor impeded access to needed services. These results were not surprising in view of the fact that HealthPASS actually did little to change provider or patient behavior with respect to obstetrical care. Both the HealthPASS and Medicaid groups experienced low rates of adequate prenatal care (39%) and high rates of low birth weight (20%). Also disturbing was the finding that at least 46% of women smoked during pregnancy, at least 20% drank alcohol, and at least 17% used cocaine. These findings support the need for continued efforts to improve both access to, and content of, prenatal care for the urban poor.
