Abstract:
BACKGROUND/CONTEXT: Women represent a small minority of practicing orthopedic surgeons and neurosurgeons, with spine surgery having a disproportionately low representation relative to other subspecialties. Previous efforts have attempted to characterize gender patterns in authorship amongst select spine journals. However, no study to our knowledge has done a comprehensive assessment of the influence of gender on academic productivity, impact, and leadership amongst academic spine faculty. PURPOSE: To evaluate the impact of gender on academic productivity, promotion to leadership positions, and career advancement among academic spine faculty in the United States. STUDY DESIGN: Cross-sectional study. PATIENT SAMPLE: Academic spine faculty associated with orthopedic residency, North American Spine Society spine fellowship programs, and American Association of Neurological Surgeons spine fellowship programs. OUTCOME MEASURES: Academic productivity as measured by publications counts, h-index, authorship ranking as well as academic rank and leadership roles METHODS: We identified all spine faculty across orthopedic residency, orthopedic spine fellowship, and neurosurgical spine fellowship programs in the United States, and abstracted academic performance characteristics, cumulative h-index, and complete publication records for each individual faculty member. Proportions of men and women by specialty, academic rank, and leadership were compared with Fisher's exact testing, and comparison of mean h-index and publication counts compared with Wilcoxon rank-sum testing. Adjusted analyses on publication count and h-index were achieved with poisson regression analysis with gender as the primary predictor adjusting for specialty, degrees, academic rank, and seniority based on time since fellowship completion. RESULTS: The representation of women among spine faculty associated with orthopedic residency and North American Spine Society spine fellowship programs was 5.6%. On average, women had 40% fewer total publications (p=.025), h-indices approximately 5 units lower than men (p=.006), 40% fewer total high-impact publications (p=.030), half the senior author publications (p=.005), and half the high-impact senior author publications (p=.007) compared to men. After adjusting for seniority and academic rank, the number of publications in high impact journals no longer differed between men and women, although differences persisted for total publication count and the h-index. Men were significantly more likely to occupy higher academic ranks, with 25.6% of men and 9.5% of women holding the rank of full professor (p=.031), although there was no significant difference in the rate of appointment to leadership positions. Similar findings were encountered among American Association of Neurological Surgeons spine fellowship faculty. CONCLUSIONS: The present study details the low rate of women in academic spine surgery. Furthermore, gender disparities exist in publication volume, impact, and h-indices. A much lower proportion of women hold higher-ranking academic positions compared to men, though appointment to leadership positions was similar between genders. Differences in seniority and publication metrics may in part be due to the relatively younger cohort of women faculty. These findings underscore the need for active investment in diversity and pipeline efforts that facilitate recruitment and support academic productivity of women in spine surgery.
