Previous work in urology has shown that men have higher h-indices than women. However, the degree to which h-indices vary by gender within urological subspecialties has not been well defined. Herein, we assess gender differences in h-index among different subspecialties.
Demographics were recorded for academic urologists using residency program websites as of July 2021. Scopus was queried to identify h-indices. Gender differences in h-index were estimated from a linear mixed-effects regression model with fixed effects for gender, urological subspecialty, MD/PhD status, years since first publication, interactions of subspecialty with years since first publication, and interactions of subspecialty with gender and random effects for AUA section and institution nested within AUA section. The Holm method was used to adjust for multiplicity (7 hypothesis tests).
Of 1,694 academic urologists from 137 institutions, 308 were women (18%). Median years since first publication was 20 for men (IQR 13, 29) and 13 for women (IQR 8, 17). Among all academic urologists, the median h-index was 8 points higher for men (15 [IQR 7, 27]) vs women (7 [IQR 5, 12]). There was no significant gender difference in h-index for any of the subspecialties after adjusting for urologist experience and after applying the Holm method for multiplicity correction.
We were unable to demonstrate a gender difference in h-index after adjusting for urologist experience for any urological subspecialties. Future study is warranted as women become more senior members of the urological workforce.
