Competition and medical groups. A survivor analysis.

This paper extends the survivor analysis of medical practice provided by Frech and Ginsburg (1974). Changes in the distribution of medical practice sizes are examined for the periods 1965-69, 1969-75, and 1975-80. Through 1975, we find that, almost uniformly, all sizes of medical groups were found to be optimal. In particular, the optimality of large (100 or more physicians) multi-specialty groups was strongly confirmed. Later data, however, suggest that the equilibrium size distribution may have shifted. For the 1975-80 period only large multi-specialty groups continue to be in the optimal size range. In addition, we find some evidence that suggests that solo practices may be optimal in some geographic regions.

Physician practice patterns under hospital rate-setting programs.

Earlier studies of hospital rate-setting programs have focused primarily on their ability to contain the growth in hospital utilization and expenditures. While most analysts recognize the central role physicians play in influencing health care utilization and expenditures, regulatory programs have been directed primarily at the hospital. At this time, it is unclear what impact, if any, these programs have had on physicians. Our study presents a preliminary analysis of this issue based on data from 1978 to 1982. When we compared average incomes, fees, and utilization of physician services in states with hospital rate regulations with those in states without such programs, we found significant differences. Average net incomes grew at a 1.9% slower annual rate in states with strict hospital regulatory programs. If hospital regulation is having some impact on physicians, both the physician and hospital sector should be considered when evaluating the ability of these programs to contain health care costs.

Variation in the growth and incidence of medical malpractice claims.

This study analyzes the incidence of medical malpractice claims since 1976, using data drawn from the 1982 core survey of the American Medical Association's Socioeconomic Monitoring System. The data show that, on average, physicians incurred twice as many claims per year in the years 1976 to 1981 as they did during their careers prior to that period. Using Tobit analysis, we find the annual frequency of claims to be greater among surgeons, obstetricians and gynecologists (OBGs), physicians in group practice, and physicians in states which apply the legal doctrine of informed consent. In addition, we find that the number of years since medical residency is positively related to physicians' claims incidence during the first 27 years of practice, and that OBGs and medical specialists who spend more time with their patients per office visit incur fewer claims.
