Employment-Based Health Insurance Is Failing: Now What?
A strategy, based on managed competition, to free employers from the health
care cost spiral and produce effective managed care.
By Alain C. Enthoven
There are two types of HMOs existing today. “Carrier HMOs” are insurance companies that offer a comprehensive benefit package, characteristic of HMOs, but deliver the services by contracting with independent doctors or medical groups whose main mode of payment remains fee-for-service (FFS). This is in contradistinction to “delivery system HMOs” that are based on their own dedicated medical groups and working mainly under per capita prepayment. The latter are a much more powerful lever for reshaping health care.
“Managed competition” is an alternative to… (current) employer policies. The idea is for the employer to increase competition by offering employees a wide choice of carriers and plan designs, a responsible choice (employees are fully responsible for premium differences), individual choice, informed choice, and multiple choices of delivery systems. If a critical mass of employers were to do this in a market, they could create conditions in which efficient delivery systems could enter, market their superior value for money, and achieve economies of scale. In managed competition, insurers need to be linked with specific, geographically overlapping delivery systems. (Six carrier HMOs, each offering practically every provider in town, would not be “competition” in this sense. The point is competition among delivery systems, not just carriers.)

Comment: In this article, Professor Enthoven identifies many of the problems inherent in the current employment-sponsored, managed care system. He continues to support his model of managed competition as the solution to our wasteful, dysfunctional system. But his model is dependent on the voluntary initiative of a “critical mass” of employers to create a market in which “geographically overlapping” delivery systems, with “economies of scale,” would compete.
Although perhaps an oversimplification, his model suggests that almost all physicians, hospitals, and other providers be placed in several Kaiser-type HMOs within the same community, without significant provider overlap. Even densely-populated urban regions would find difficulties supporting multiple, large, integrated delivery systems. And experience has shown that many suburban and almost all rural areas cannot support even a single integrated delivery system. This does not mean that integrated delivery systems should be excluded as a form of health care delivery, but they can never be relied on as the dominant model in all communities, unless as a universal, public health service model.
There are critical issues that must be addressed during our efforts to reform the funding of health care. Ensuring affordable access to comprehensive services for everyone must be our primary mission. A mission of establishing an artificial business model designed specifically to enhance marketplace competition, regardless of the negative impact on patients, misses our priorities for reform, and should be discarded as the inadequate and highly flawed concept that it is.
