Abstract
Promotion in academia heavily relies on research productivity. The h-index is a standardized metric used to quantify research productivity at the individual level. We evaluated factors associated with h -index in dermatology across select Canadian academic centers with special focus on sex and academic rank. Medical academic centers throughout Canada with dermatology training programs were included. For each faculty member, we extracted the following data from public sources: sex, graduate degree, academic rank, years since the Fellow of the Royal College of Physicians and Surgeons of Canada (FRCPC) certification or equivalent, recent Canadian Institutes of Health Research (CIHR) funding and H-index (based on Scopus author profile). Log-linear univariate and multivariate regression analyses were performed to evaluate the association between h-index and these factors. An ordinal logistic regression was performed to explore sex differences in academic ranking. Our results showed that out of 300 faculty members across Canada, 155 were females (51.67%) and 145 were male (48.33%). H-index was available for 279 dermatologists. The average h-index was 8.35 (SD 11.53) and the median was 4.00 (1st quartile = 2.00, 3rd quartile = 10.00). Higher h-index was associated with more years since dermatology certification, successive academic rank, graduate degree and recent CIHR funding, but not with sex. In conclusion, h-index was not associated with sex when controlling for potential confounders. These results could reflect recent demographic changes in the field with an increase in newly appointed female dermatologists. Longitudinal assessment of academic productivity in dermatology is needed to assess the impact of continued efforts to promote equal opportunities in the field.
