    An Assessment of the Academic Impact of Shock Society Members
    (Wolters Kluwer, 2018-05) Milgrom, Daniel P.; Koniaris, Leonidas G.; Valsangkar, Nakul P.; Lad, Neha; Bell, Teresa M.; Wojcik, Brandon; Zimmers, Teresa A.; Surgery, School of Medicine
    Professional society membership enhances career development and productivity by offering opportunities for networking and learning about recent advances in the field. The quality and contribution of such societies can be measured in part through the academic productivity, career status, and funding success rates of their members. Here, using Scopus, NIH RePORTER, and departmental websites, we compare characteristics of the Shock Society membership to those of the top 55 NIH-funded American university and hospital-based departments of surgery. Shock Society members' mean number of publications, citations and H-indices were all significantly higher than those of non-members in surgery departments (P < 0.001). A higher percentage of members also have received funding from the NIH (42.5% vs. 18.5%, P < 0.001). Regression analysis indicated that members were more likely to have NIH funding compared with non-members (OR 1.46, 95% CI 1.12-1.916). Trauma surgeons belonging to the Shock Society had a higher number of publications and greater NIH funding than those who did not (130.4 vs. 42.7, P < 0.001; 40.4% vs. 8.5%, P < 0.001). Aggregate academic metrics from the Shock Society were superior to those of the Association for Academic Surgery and generally for the Society of University Surgeons as well. These data indicate that the Shock Society represents a highly academic and productive group of investigators. For surgery faculty, membership is associated with greater academic productivity and career advancement. While it is difficult to ascribe causation, certainly the Shock Society might positively influence careers for its members.

    Does the h-index and self-citation affect external funding of orthopedic surgery research? An analysis of fellowship directors and their subspecialties
    (Elsevier, 2020-01-22) Ernat, Justin J.; Yheulon, Christopher G.; Lopez, Andrew J.; Warth, Lucian C.; Orthopaedic Surgery, School of Medicine
    Purpose: Determine the impact of self-citation on external funding for orthopedic fellowship directors. Methods: The San Francisco Match's website identified directors encompassing 8 subspecialties. The Scopus database identified the number of publications, citations, and h-index for each director. H-index was assessed with/without self-citation. Results: Mean publications, citations, self-citation rate, and h-index for the 446 directors were 71.2, 1816, 3.86%, and 18.3, respectively. Excluding self-citations reduces mean h-index to 18.0; and h-index changed by ≤ 1 integer in 95% of directors. Conclusions: Self-citation has minimal impact among fellowship directors and should not be adjusted for when considering external funding.

    NIH Funding, Research Productivity, and Scientific Impact: a 20-Year Study
    (Springer, 2022) Agarwal, Rajiv; Tu, Wanzhu; Medicine, School of Medicine
    Background: The Research Project Grant (R01) is the oldest grant mechanism used by the National Institutes of Health (NIH). Receiving an R01 award is often taken as a sign of scientific success. We presented normative data on multiple productivity and impact metrics for a more objective assessment of funded grants' scientific success. Methods: All initial R01 grants awarded by NIH in the year 2000 were prospectively followed and evaluated using the numbers of publications and citations, as well as the h-indices at the grant level. We examined the variability, time trends, and relations among these metrics to better understand the funded projects' cumulative output and impact. Results: In the 20 years since initial funding, 4451 R01 grants generated a total of 55,053 publications. These publications were cumulatively cited 3,705,553 times over 736,811 citation years. The median number of publications was 8 (25th, 75th percentiles 4, 17) per grant for the entire 20-year duration. The median number of citations and the median h-index were 441 (25th, 75th percentiles 156, 1061) and 7 (25th, 75th percentiles 4, 13) per grant, respectively. The time courses of publication, citation, and accumulation of h-index were highly variable among the awarded grants. Although the metrics were correlated within an award, they reflected the grant's success in different domains. Conclusion: Numbers of publications, citations, and h-indices vary greatly among funded R01 grants. When used together, these metrics provide a more complete picture of the productivity and long-term impact of a funded grant.
