The domino effect: the impact of gender on operative self-efficacy

Studies suggest that there are key differences in operative experience based on a trainee's gender. A large-scale self-efficacy (SE) survey, distributed to general surgery residents after the American Board of Surgery In-Training Examination in 2020, found that female gender was associated with decreased SE in graduating PGY5 residents for all 4 laparoscopic procedures included on the survey (cholecystectomy, appendectomy, right hemicolectomy, and diagnostic laparoscopy). We sought to determine whether these differences were reflected at the case level when considering operative performance and supervision using an operative assessment tool (SIMPL OR).

Supervision and performance data reported through the SIMPL OR platform for the same 4 laparoscopic procedures included in the SE survey were aggregated for residents who were PGY5s in 2020. Independent t-tests and multiple linear regression were used to determine the relationship between trainee gender and supervision/performance ratings.

For laparoscopic cases in aggregate (n = 2708), male residents rated their performance higher than females (3.57 vs. 3.26, p < 0.001, 1 = critical deficiency, 5 = exceptional performance) and reported less supervision (3.15 vs. 2.85, p < 0.001, 1 = show and tell, 4 = supervision only); similar findings were seen when looking at attending reports of resident supervision and performance. A multiple linear regression model showed that attending gender did not significantly predict resident-reported supervision or performance levels, while case complexity and trainee gender significantly affected both supervision and performance (p < 0.001).

Female residents perceive themselves to be less self-efficacious at core laparoscopic procedures compared to their male colleagues. Comparison to more case-specific data confirm that female residents receive more supervision and lower performance ratings. This may create a domino effect in which female residents receive less operative independence, preventing the opportunity to establish SE. Further research should identify opportunities to break this cycle and consider gender identity beyond the male/female construct.
