• To describe the characteristics of beneficiaries who disenrolled from these Medicare HMOs.
• To provide a preliminary analysis of the implications of Medicare HMO disenrollment.

Main Methods:

• Descriptive analysis of disenrollment data from 17 Medicare Competition Demonstration HMOs.
• Examination of beneficiary characteristics using data from two surveys conducted in early 1985 and 1986.
• Focus on a sample of Medicare beneficiaries.

Main Results:

• Preliminary identification of patterns in Medicare HMO disenrollment during the study period.
• Characterization of the demographic and other attributes of Medicare beneficiaries who disenrolled.
• Initial insights into the nature and potential consequences of disenrollment from Medicare HMOs.

Conclusions:
