Disenrollment rates from Medicare man-aged care plans have been reported to thepublic as an indicator of health plan quali-ty.

patient care experiences. We hypoth-esized that disabled beneficiaries may beaffected differently than other beneficiariesby
competitive market factors, due to higherexpected expenditures and impaired mobili-ty. Findings suggest that disabled beneficia-ries
are more likely to experience multipleproblems with managed care.
