Abstract
BACKGROUND: H-index distinguishes differences in scholarly output across faculty ranks in anaesthesiologists, but whether h-index also identifies differences in other aspects of productivity is unknown. We tested the hypothesis that h-index is an indicator of not only publication record, but also grant funding and mentoring in highly productive US academic anaesthesiologists. METHODS: We conducted an internet analysis of the Foundation for Anesthesia Education and Research Academy of Research Mentors in Anesthesiology (n = 43). Publications, citations, citations per publication, and h-index for each investigator were obtained using the Scopus(®) . Total grants, active grants, years of funding, and duration of longest funded grant were recorded using the US National Institutes of Health Research Portfolio Online Reporting Tools(®) . Members were surveyed to identify the number of their career trainees and those who obtained independent funding. RESULTS: The median [IRQ (Interquartile range)] h-index of members was 23 [17-32 (8-50)]. Members published 136 [100-225 (39-461)] papers with 3573 [1832-5090 (150-11,601)] citations and 21 [15-32 (4-59)] citations per publication. Members received four [3-7 (0-10)] grants and were funded for 29 [17-45 (0-115)] grant-years. Survey respondents (79%) mentored 40 [26-69 (15-191)] trainees, three [2-6 (0-20)] of which subsequently received funding. Members with h-indices greater than the median had more publications, citations, citations per publication, grants, and years of funding compared with their counterparts. H-index was associated with total citations, active grants, and the number of trainees. CONCLUSIONS: In addition to publication record, h-index sensitively indicates grant funding and mentoring in highly productive US academic anaesthesiologists. 2011 The Authors.
