No Quality Differences in Medicare Diabetes Care: Managed Care or Fee-for-Service

Research and policy experts often assume that growth in the market penetration of managed care organizations and the incentives they use to control costs have a "spillover" effect (i.e., an effect beyond the managed care market) on the health care received by Medicare fee-for-service beneficiaries.

From 2002 to 2003, investigators from the Mount Sinai School of Medicine of New York University tested whether this assumption is true for Medicare managed care patients with diabetes.

This project was part of the Robert Wood Johnson Foundation (RWJF) national program Changes in Health Care Financing and Organization (HCFO).

Key Findings

  • Researchers found little evidence to suggest such a spillover effect for the studied diabetes population.
