Abstract
Hirsch-index (or h-index) is a bibliometric measure calculated for researchers based on number of publications and their citations. This study examined the h-index of board-certified plastic surgeons in Saudi Arabia and the different factors that may influence it. METHOD: In this cross-sectional study, an electronic questionnaire was sent to 156 board-certified plastic surgeons practicing in Saudi Arabia. Using their names, we conducted an online search on Scopus, Semantic scholar, and Google scholar to calculate their h-index. Bivariate and multiple regression analyses were conducted to determine the relationship of those factors with the index. RESULTS: A total of 84 surgeons participated in this study, of whom 83.3% were men. Our sample scored a mean index of 1.7 and published a mean of 5 articles. More publications and a higher academic rank predicted a higher h-index, (β = 0.79, P < 0.001) and (β = 0.14, P 0.017), respectively. On the other end of the spectrum, the country of residency training (P 0.33), the year of training completion (P 0.95), attaining fellowship training (P 0.95), the number of fellowships (P 0.20), interest in research (P 0.74), working in an academic hospital (P 0.44), or attaining a higher degree (P 0.61) were not significant independent predictors of the index. CONCLUSIONS: More publications and a higher rank predicted increased academic productivity among the plastic surgeons in Saudi Arabia. Despite its limitations, h-index is a useful measure that can be considered in promotions and applications to prestigious plastic surgery centers in adjunct to other factors.
