Insights
Competition proposals may not significantly reduce medical care costs by influencing physician behavior. Their value may lie in better aligning consumer needs with provider services, rather than direct cost reduction.
Area of Science:
- Health economics
- Medical practice management
Background:
- Competition proposals aim to reduce healthcare costs, often focusing on health insurance markets.
- The transmission mechanisms by which policies influence physician behavior remain unclear.
Purpose of the Study:
- To evaluate the potential of competition proposals to reduce medical care costs through physician behavior modification.
- To assess the role of physician groups in competitive healthcare models.
Main Methods:
- Analysis of existing literature and economic hypotheses regarding physician practice structures and competition.
- Examination of productivity and fee level differences between solo and group practices.
Main Results:
- The effect of competition on physician behavior is hypothesized to be uneven, with group practices concentrated in already competitive urban areas.
- Limited evidence exists for productivity or fee level differences between solo and group physicians.
- The value of group medical practices hinges on their potential to reduce the utilization of expensive medical services.
Conclusions:
- Competition proposals may offer limited promise for direct cost reduction in medical care.
- These proposals might be valuable for improving the alignment of consumer preferences with provider services compared to the current system.
Abstract:
If competition proposals are to reduce the cost of medical care, they must put forth a key role for physicians. Inasmuch as most proposals focus on the market for health insurance, the means by which policies that affect insurers are transmitted to influence the behavior of physicians are largely unknown. A larger role for competing groups of physicians is hypothesized, but the effect of competition is likely to be uneven, because group practice physicians are already in the most competitive areas of the country in terms of the density of physicians, and very few are in rural areas or in other particular regions of the country. Little evidence can be found in productivity or fee level differences between solo and group practice physicians. Thus the value of promoting group medical practices rests on their ability to reduce the use of expensive medical care. It is possible that competition proposals may not hold much promise for reducing costs. Nevertheless, they may still be worthwhile if they are better able than the present system to translate the wishes of consumers into the services of providers.
