[Primary care in Québec: a comparison between private practitioners and physicians working in public community health centers].

Since the early 1970s, there have been two primary care networks in Quebec: the traditional one characterized by fee-for-service; and the public one regrouping 10% of physicians and characterized by a salaried practice within publicly funded local institutions known as CLSCs. Using 1984 data collected on 616 Quebec generalists, 333 in private practice and 283 in CLSCs, we compared the physicians' profile in both networks. In contrast to their colleagues in private practice, CLSC physicians were younger, more often female and more involved in rural practice as well as in community health. They also differed in their attitudes and to some extent in their clinical practices. Overall, the study suggests that the introduction of a public primary care network has served to facilitate the emergence of a more comprehensive type of medical practice in the Quebec health care system.

Factors influencing physicians' preventive practices.

We used data on a stratified random sample of 809 Quebec physicians to determine the extent to which the integration of prevention into medical practice was related to physicians' sociodemographic background, area of specialization, medical practice characteristics, and professional attitudes. Among factors positively associated with physicians' preventive practices were favorable attitudes toward prevention, patient education and patient-oriented activities, being in primary care medicine or in a medical specialty such as cardiology, gastroenterology, or pneumology, practicing in a public community health center on a salary basis, working in a group practice, having an office-based practice, devoting time to research activities, being older, and being a woman. Specialization in neurology, hematology, dermatology, nephrology, obstetrics-gynecology, and most notably surgery was negatively associated with preventive practices, as was working in an emergency room. Overall, the study variables explained 33% of the variance in physicians' preventive practices. The study underlines the prevailing role of attitudes in predicting physicians' preventive practices.

The professional attitudes and practice characteristics of male and female specialists.

Using data obtained from a mail survey of 119 female and 140 male specialists conducted in Quebec in 1983-1984, we compared men and women on their attitudes and on the organizational, professional, and clinical characteristics of their medical practices. Analyses were performed separately for medical and surgical specialists. Gender differences in the clinical practice of medical specialists were found, with women reporting greater attention to the social, preventive, and human aspects of patient care than men. Among surgical specialists, women expressed more favorable attitudes toward the social component in health care than their male colleagues. They also differed from men on indicators measuring various practice characteristics. These findings may reflect gender differences in type of surgical specialty, since the majority of female surgeons were in ophthalmology. Overall, fewer women specialists reported that they had assumed administrative responsibilities. The implications of these results are discussed in the context of the increasing feminization of the medical profession.

[Climatologic parameters and myocardial infarction].

535 patients admitted to hospital with myocardium infarct which was confirmed in a determined period and within a 80 kilometers radius from a city of the East of France were compared to the meteorological parameters of the day when the infarct occurred and of the day preceding its occurrence. On one hand, climatic parameters were selected: atmospheric pressure, temperature of the air under shelter, relative humidity, wind speed and wind direction, hydrometeors and electrometeors; on the other hand, parameters of solar and planetary activity: daily flare index, AA index, Ap index or daily planetary index, phases of the moon. The analytic study concerning all acute vascular accidents (infarcts and cerebral accidents all together) enabled to us to notice a higher frequency of vascular accidents in various meteorological circumstances: atmospheric pressure lower than 990 mb, temperature lower than 12 degrees, wind of sector North to South-South West, hoar-frost with fog, rain, snow, first quarter of the moon, daily flare index lower than 530, magnetic activity lower than 6. A factorial analysis of correspondence enabled to us to understand the problem better and to determine "an infarct area" in which main meteorological factors appeared: low or decreasing atmospheric pressure, relative or increasing humidity, clear or increasing solar activity, steady magnetic activity; other factors could play an apparently less important role: low temperature, snow, decrease of wind speed, full moon, wind of sector East to North-East, South-South West. Consequently it appeared in that study that the occurrence of myocardium infarct corresponded to a climatic tendency corresponding to cold, bad or deteriorating weather.
