Female representation in the Canadian physician anesthesia workforce: a historical analysis.

Abstract

Purpose: According to an analysis of data from the Canadian Institutes for Health Information (CIHI) National Physician Database, the proportion of female anesthesia physicians is substantially lower than the proportion of female physicians in the total physician population. The goal of this study was to identify trends in female representation in the major subgroups of anesthesia providers, including specialists certified by the Royal College of Physician and Surgeons of Canada (RCPSC), international medical graduates, and family physician anesthetists (FPAs).

Methods: We examined the sex distribution of the existing physician workforce, including anesthesia providers working in urban and rural Canada, using the CIHI National Physician Database (1996-2018). We also examined the sex distribution of physicians entering the workforce using the Canadian Post-MD Education Registry database and calculated descriptive statistics.

Results: The proportion of female physicians increased steadily over time in all groups; nevertheless, the numbers of female FPAs and rural anesthesia providers continued to lag relative to all Canadian physicians (9.4%, 9.4%, and 26.7%, respectively, in 1996; 18.7%, 21.1%, and 42.1%, respectively, in 2018). Of the graduates from RCPSC training programs in 1996, 28% were female, whereas by 2018, 33.5% of graduates were female.

Conclusions: Female physicians were underrepresented in all subgroups, but the proportions were lowest among FPAs and rural physicians. Given that greater sex diversity in clinical teams is associated with better outcomes, and in light of ongoing workforce shortages, the barriers that prevent female physicians from entering and/or remaining in the anesthesia workforce need to be understood and ameliorated.
