Introduction: Historically low, the proportion of female urology residents now exceeds 25% in recent years. Simulation of surgical skills is increasingly common in modern residency training and can allow for objective assessment of technical skills. The objective of this study was to identify gender differences in self-assessment of surgeons and trainees.
Methods: Medical students, residents, attending and retired surgeons completed simple interrupted (SIS) and running subcuticular suturing (RSC) tasks. Assessment was self-rated using previously tested visual analog motion scales. Tasks were video recorded and rated using identical motion scales by blinded expert surgeons who had undergone training to standardize their assessment.
Results: Female (n=17) and male (n=20) participants were equally distributed by level of training (medical students, n=10; residents, n=15; attending and retired surgeons, n=12), p=0.76. Five expert surgeons evaluated 220 30-second video segments of suturing tasks (mean 3.0 segments per task per participant). Self-assessment correlated well overall with expert rating for SIS, RSC tasks in the following domains, respectively: motion economy (p < 0.001, p < 0.001), motion fluidity (p=0.002, p < 0.001), coordination (p=0.001, p=0.764) and tissue handling (p=0.120, p=0.001). _x000D_
Mean individual difference of self-assessment and expert assessment scores (ï„ SAS-ERS) differed by gender in the domains of motion economy (-1.1ï‚±1.6 female vs -0.2ï‚±1.6 male, p=0.08 for RSC) and fluidity of motion (-1.2ï‚±1.6 female vs -0.1ï‚±1.8 male, p=0.04 for SIS). ï„ SAS-ERS was similar in the domains of tissue handling and coordination. ï„ SAS-ERS did not differ significantly in any domains across levels of training. Expert ratings did not differ significantly by gender for any domain.
Conclusions: Female surgeons and trainees under rate some technical skills on self-assessment when compared with expert ratings, while male surgeon and trainee self-ratings were concordant with experts. Further work is need to determine if these differences are accentuated across increasingly difficult tasks.
