Blinded intraoperative skill evaluations avoid gender-based bias.

INTRODUCTION

Gender bias has been identified consistently in written performance evaluations. Qualitative tools may provide a standardized way to evaluate surgical skill and minimize gender bias. We hypothesized that there is no difference in operative time or GEARS scores in robotic hysterectomy for men vs women surgeons.

METHODS

Patients undergoing robotic hysterectomies performed between June 2019 and March 2020 at 8 hospitals within the same hospital system were captured into a prospective database. GEARS scores were assigned by crowd-sourced evaluators by a third party blinded to any surgeon- or patient-identifying information. One-way ANOVA was used to compare the mean operative time and GEARS scores for each group, and significant variables were included in a one-way ANCOVA to control for confounders. Two-tailed p-value < 0.05 was considered significant.

RESULTS

Seventeen women and 13 men performed a total of 188 hysterectomies; women performed 34 (18%) and men performed 153 (81%). Women surgeons had a higher mean operative time (133 ± 58 vs 86.3 ± 46 min, p = 0.024); after adjustment, there were no significant differences in operative time (p = 0.607). There was no significant difference between the genders in total GEARS score (20.0 ± 0.77 vs 20.2 ± 0.70, p = 0.415) or GEARS subcomponent scores: bimanual dexterity (3.98 ± 0.03 vs 4.00 ± 0.03, p = 0.705); depth perception (4.04 ± 0.04 vs 4.05 ± 0.02, p = 0.799); efficiency (3.79 ± 0.02 vs 3.82 ± 0.02, p = 0.437); force sensitivity (4.01 ± 0.04 vs 4.05 ± 0.05, p = 0.533); or robotic control (4.16 ± 0.03 vs 4.26 ± 0.01, p = 0.079).

CONCLUSION

There was no difference in GEARS score between men vs women surgeons performing robotic hysterectomies. Video-based blinded assessment of skills may minimize gender biases when evaluating surgical skill for competency evaluation and credentialing.
