ObjectiveDespite the increasing representation of females in neurosurgical training, the fraction of female to male neurosurgeons decreases dramatically as faculty rank (Assistant, Associate, or Full Professor) increases. To assess this discrepancy, we quantified self-reported time-to-promotion trajectories for female and male neurosurgeons holding academic appointments.MethodsIn this cross-sectional institutional review board (IRB)-approved study, 147 female and 84 male neurosurgeons currently holding faculty positions in the US were contacted via email and invited to complete an anonymous, standardized survey. Respondents provided the calendar year of postgraduate training completion, promotion to different faculty ranks, geographic region of current practice (Western, Midwest, Southern, Northeast), and practice subspecialty.ResultsThe response rate was 44.2% for females and 59.5% for males, with 114 participants included (65 female, 49 male). On average, female neurosurgeons required 25% longer to become an Associate Professor (P = 0.017), 34% longer to become a Full Professor (P = 0.004), 37% longer for promotion from Assistant to Associate Professor (P < 0.001), and 32% longer from Assistant to Full Professor (P = 0.012). Promotion timelines did not vary by region or specialty among male and female cohorts. Linear regressions revealed that female neurosurgeons with more recent training completion experienced shorter time-to-promotion to Associate and Full Professor compared to females of earlier generations (P = 0.005 and 0.001, respectively), while male timelines remained stable.ConclusionsThis study identifies a significant delay in time-to-promotion for female neurosurgeons compared to their male counterparts. Investigation and standardization of promotion timelines are necessary to ensure meaningful representation gains from the increased number of women entering neurosurgical training.Copyright © 2023 Elsevier Inc.
