Women in medicine: practice patterns and attitudes.

Increasing numbers of women are entering medicine in Canada. In 1959 women accounted for 6% of the medical school graduates, but by 1989 they accounted for 44%. Although there has been little systematic investigation of the impact of this increase on Canada's health care system, there are grounds for believing that female physicians bring with them distinctive values and interests, which may be reflected in the way they conduct their professional practices. We used data from a recent national survey of 2398 Canadian physicians to examine differences between women and men in their practices and their attitudes toward health care issues. Significant differences were found in the organization and management of the practices. Women preferred group over solo practice and were overrepresented in community health centres, health service organizations and centres locaux de services communautaires in Quebec. One-third of the women, as compared with half of the men, were in specialties. Even after adjusting for differences in workloads the incomes of the women were significantly lower than those of the men. Only minor differences were observed in the assessment of the health care system and alternative modes of organizing health care services. We believe that the differences were due to the double workload of women as professionals and family caregivers and the powerful socialization effects of medical education. As women overcome their minority status in the medical profession, differences between the sexes may become more apparent. Thus, the extent and effects of the progressive increase in the number of women in Canadian medicine should be assessed on an ongoing basis.

Do practice guidelines guide practice? The effect of a consensus statement on the practice of physicians.

Guidelines for medical practice can contribute to improved care only if they succeed in moving actual practice closer to the behaviors the guidelines recommend. To assess the effect of such guidelines, we surveyed hospitals and obstetricians in Ontario before and after the release of a widely distributed and nationally endorsed consensus statement recommending decreases in the use of cesarean sections. These surveys, along with discharge data from hospitals reflecting actual practice, revealed that most obstetricians (87 to 94 percent) were aware of the guidelines and that most (82.5 to 85 percent) agreed with them. Attitudes toward the use of cesarean section were congruent with the recommendations even before their release. One third of the hospitals and obstetricians reported changing their practice as a consequence of the guidelines, and obstetricians reported rates of cesarean section in women with a previous cesarean section that were significantly reduced, in keeping with the recommendations (from 72.2 percent to 61.1 percent; P less than 0.01). The surveys also showed, however, that knowledge of the content of the recommendations was poor (67 percent correct responses). Furthermore, data on actual practice after the publication of the guidelines showed that the rates of cesarean section were 15 to 49 percent higher than the rates reported by obstetricians, and they showed only a slight change from the previous upward trend. We conclude that guidelines for practice may predispose physicians to consider changing their behavior, but that unless there are other incentives or the removal of disincentives, guidelines may be unlikely to effect rapid change in actual practice. We believe that incentives should operate at the local level, although they may include system-wide economic changes.
