On the "efficiency" of managed care plans.
The claim that managed care plans are more efficient than fee-for-service plans has been made so often that it has reached the status of folklore, but the evidence is inconclusive. The claim is usually based on one or both of the following errors: (1) lower medical care costs mean lower total costs (medical plus administrative costs) and (2) lower HMO premiums mean HMOs are more efficient than fee-for-service plans. The first assertion ignores evidence indicating that managed care has driven up administrative costs for both insurers and providers. The second ignores evidence that managed care plans have numerous methods of shifting costs that are unavailable or less available to fee-for-service plans. The lull in health care inflation during the mid-1990s is often cited as evidence that managed care is efficient. But the lull may have been caused not by the spread of managed care but by the near-simultaneous occurrence of four events: a downturn in the insurance underwriting cycle, the 1990-1991 recession, endorsement of managed competition by numerous politicians, and the merger fever triggered by those endorsements.
