摘要：OBJECTIVES: This study evaluated New York City's voluntary Medicaid managed care program in terms of health care use and access. METHODS: A survey of adults in Medicaid managed care and fee-for-service programs during 1996-1997 was analyzed. RESULTS: Responses showed significant favorable risk selection into managed care but little difference in use of health care services. Although some measures of access favored managed care, many others showed no difference between the study groups. CONCLUSIONS: The early impact of mandatory enrollment will probably include an increase in the average risk of managed care enrollees with little change in beneficiary use and access to care.
