Gender bias has been described in the anesthesiology profession. Inequalities in compensation and career advancement have been reported. Gender-based assumptions, such as the perception of women as less agentic (associated with stereotypically masculine qualities such as independence and ambition) and more communal (associated with stereotypically feminine qualities such as gentleness and dependence), are a possible explanation for these gender-based discrepancies. We hypothesized that female anesthesia attendings are assigned at increased frequency to residents and produce less ASA units and less RVUs, compared to male colleagues.
