Abstract
PURPOSE: To evaluate the association between the Hirsch index (a measure of publications and citations) and academic rank among hand surgeons. METHODS: This was a cross-sectional study of full-time academic hand surgeons within Accreditation Council for Graduate Medical Education-approved hand surgery fellowship programs in the United States and Canada. The study variables were classified as bibliometric (h-index, I-10 index, total number of publications, total number of citations, maximum number of citations for a single work) and demographics (gender, training factors). The outcome was academic rank (instructor, assistant professor, associate professor, professor, endowed professor). Descriptive, bivariate, and multiple regression statistics were computed. RESULTS: The sample was composed of 366 full-time academic hand surgeons; 86% were male and 98% had formal hand surgery fellowship training. The mean time since completion of surgical training was 17 ± 11 years. The distribution of primary faculty appointments was orthopedic surgery (70%) and plastic surgery (30%). Two hundred fifty surgeons (68%) were members of the American Society for Surgery of the Hand. The mean h-index was 10.2 ± 9.9 and was strongly correlated with academic rank. Gender was not associated with academic rank. Distribution of academic ranks was as follows: instructor (4%), assistant professor (28%), associate professor (40%), professor (22%), and endowed professor (5%). The h-index, years since completion of training, and American Society for Surgery of the Hand membership were associated with academic rank. The h-index had a high sensitivity and specificity for predicting academic rank. CONCLUSIONS: The h-index is a reliable tool for quantitatively assessing research productivity and should be considered for use in academic hand surgery. CLINICAL RELEVANCE: When evaluating candidates for academic promotion in hand surgery, the h-index is a potentially valuable tool for assessing research productivity and impact.
