Data are utilized collected from the American Association of Health Plans, a trade association representing HMOs, to study differences in utilization patterns between Medicare beneficiaries enrolled in Medicare risk and cost contracts with health plans. Utilization is measured by the number of ambulatory procedures performed, outpatient and emergency room visits, and acute and nonacute discharges. Compared to elders enrolled in risk plans, those in cost arrangements appear to exhibit higher inpatient and outpatient use. Members of for‐profit plans experienced greater outpatient visits, accreditation did not appear to influence utilization, and IPA arrangements resulted in a decrease in outpatient utilization. Financial and policy issues are discussed.
