Do health maintenance organizations work for Medicare?

Area of Science:

• Health Services Research
• Health Economics
• Public Health Policy

Background:

• The Health Care Financing Administration (HCFA) has promoted health maintenance organizations (HMOs) for Medicare coverage since 1985.
• HMOs operate on a capitation model, receiving fixed prepaid premiums for providing care to enrolled beneficiaries.

Purpose of the Study:

• To evaluate the effectiveness of the Medicare risk program involving HMOs.
• To assess whether HMOs meet the goals set by the HCFA in terms of quality, resource utilization, and cost savings for Medicare.

Main Methods:

• Comparative analysis of healthcare quality and resource use between HMOs and traditional free-for-service (FFS) providers.
• Evaluation of out-of-pocket costs and coverage for enrollees in HMOs.
• Assessment of the program's financial impact on Medicare, considering enrollee health status.

Main Results:

• HMOs deliver care of comparable quality to FFS providers while utilizing fewer healthcare resources.
• Medicare enrollees in HMOs report significantly lower out-of-pocket expenses and broader coverage.
• The capitation system does not result in Medicare savings, as it fails to adjust for the healthier population enrolling in HMOs.

Conclusions:

• HMOs provide valuable benefits to Medicare beneficiaries, including comparable quality care, reduced personal costs, and enhanced coverage.
• The current Medicare risk program structure, reliant on capitation without risk adjustment for health status, does not achieve cost savings for Medicare.
• Policy adjustments are needed to ensure the financial viability of the program for Medicare while maintaining enrollee benefits.
