Disciplined physicians were more likely to practice in psychiatry, child psychiatry, obstetrics and gynecology, and family and general practice than nondisciplined physicians and were older than the national physician population, but were no more or less likely to be board certified than all physicians in the country. The increased frequency of discipline for sex-related offenses over time found in our study is in agreement with a report by the Federation of State Medical Boards, which found that the percentage of actions that involved sexual misconduct had increased from 2.6% in 1990 to 3.9% in 1992.
