    Background: The h-index is a commonly used bibliometric in academic medicine which enumerates the number of publications (h) that have been cited h times. Recent investigations have suggested that gender-based differences in h-index may exist among academic physicians. We systematically reviewed studies of academic surgeons’ h-index, hypothesizing that a significant difference would exist between the h-index of men and women at all academic ranks. Methods: Peer-reviewed journal articles authored by academic surgeons of any subspecialization in the United States between January 1, 2006, and November 20, 2017, were reviewed. We excluded studies of trainees or gender-based differences in funding without mention of h-index. Two reviewers assessed article quality using the Newcastle-Ottawa criteria. Pooled estimates of standard mean differences (SMD) in h-index between genders were calculated using random-effects meta-analyses. A subgroup analysis based on the academic rank was performed. Heterogeneity was assessed using the I 2 statistic. Sensitivity analyses determined the effect of study on h-index. Meta-regression identified whether surgical specialty contributed to heterogeneity. Results: Twelve articles comparing h-index between genders were selected from 7950. Men possessed higher h-indices than women (SMD, 0.547; P < 0.001; I 2 = 89.5%). Men exhibited higher h-indices at the assistant rank (SMD, 0.12; 95% confidence interval [CI], 0.01-0.24; P = 0.039) but not at the associate (SMD, 0.14; 95% CI, −0.06 to 0.33; P = 0.165) or full professor (SMD, 0.12; 95% CI, −0.08 to −0.31; P = 0.25) ranks. Conclusions: The h-index is higher for men than that for women in academic surgery overall but not at individual ranks. Further investigations are necessary to address limitations in h-index and to further characterize the relationship between h-index, gender, and promotion. © 2018 Elsevier Inc.

    Background: Terms such as “glass ceiling” and “sticky floor” are still commonly used to describe women’s role in academic surgery. Despite continued efforts to address disparities between men and women in the field, gender inequalities persist. Methods: In this investigation we highlight gender differences in published surgical literature by both quantity and impact. Websites for departments of surgery of three academic centers were reviewed to assess the bibliometrics of publications by gender over a two-week period. Results: A one-way ANOVA showed a significantly higher H-index for men than women (p > .05). Further, one-way ANOVA showed significantly more articles published by men than women (p = .019). These differences are most dramatic at the rank of associate professor where the H-index for men is three times that of the women. The rank of full professor showed men had double the number of articles published. Conclusions: These findings align with the previous research that shows a disparity between males and females as they climb the academic ladder. Conducting and publishing research is a vital part of advancement in academic medicine. This study suggests that publication productivity may be a factor that hinders women from advancing within surgery compared to men. Continuing to explore and identify reasons for this gender difference in academic surgery may highlight ways to address the imbalance. © 2017 The Author(s).

    OBJECTIVE. The purpose of this study is to determine whether academic achievement differs by gender among breast imaging radiologists. MATERIALS AND METHODS. We examined the gender disparity in academic breast radiology using several parameters, including the h-index, the number of publications, and the number of citations. We also inspected gender disparity in academic ranks and leadership ranks. RESULTS. The research productivity of female breast imagers was found to be significantly lower than that of male colleagues across all academic ranks (p < 0.001). In addition, no correlation was noted between female gender and leadership positions (p = 0.57), despite the fact that women dominate the specialty of breast imaging. CONCLUSION. The number of publications by female radiologists has risen steadily over time; however, a significant gender disparity is seen in scholarly productivity. �© American Roentgen Ray Society.

    Background: Gender disparities in academic promotion and leadership are well documented. Scholarly impact is essential for promotion. The Hirsch-index (h-index) is a measure of impact using number of publications and citations. We sought to (i) evaluate breast surgery fellowship faculty in North America by academic rank and research impact using the h-index, (ii) determine whether there is a gender difference in scholarly productivity, and (iii) determine the relationship between academic rank, h-index, and gender. Materials and Methods: A retrospective cross-sectional study of h-index and academic rank disparity in breast surgery faculty by gender was performed. We reviewed the faculty of Society of Surgical Oncology-accredited breast surgery fellowships in February 2019. Rank, gender, academic appointment, years in practice, program directorship, National Cancer Institute-designated cancer center association, size of the program, and h-index (via Scopus) were recorded. Univariate and multiple linear regression analyses were performed. Results: Fifty-two programs were identified, and 209 faculty had an h-index. Of them, 69.9% were women and 30.1% were men. h-index increased with academic rank although there was considerable overlap between ranks. Women were underrepresented at the professor level (46.4%), but accounted for the majority of assistant professors (91.5%, p < 0.001), and program directors (70.7%). Men professors had a significantly higher mean h-index than women professors, p < 0.001. However, women associate professors had a higher mean h-index than men, but this did not reach significance. Conclusions: Mean h-index increased with increasing rank among breast surgery faculty for both genders. Average h-index was significantly higher for men professors compared to women professors. No significant gender difference in h-index was found for assistant professors. For associate professors, h-index for women was higher than for men. Women are underrepresented at higher academic ranks despite forming the majority of breast surgical teaching faculty.

    Introduction: Research productivity is one of the few quintessential gauges that North American academic radiology departments implement to determine career progression. The rationale of this study is to quantify the relationship of gender, research productivity, and academic advancements in the musculoskeletal (MSK) radiology to account for emerging trends in workforce diversity. Methods: Radiology residency programs enlisted in the Fellowship and Residency Electronic Interactive Database (FREIDA), Canadian Resident Matching Service (CaRMS) and International Skeletal Society (ISS) were searched for academic faculty to generate the database for gender and academic profiles of MSK radiologists. Bibliometric data was collected using Elsevier’s SCOPUS archives, and analyzed using Stata version 14.2. Results: Among 274 MSK radiologists in North America, 190 (69.34%) were men and 84 (30.66%) were women, indicating a statistically significant difference (χ2 = 6.34; p value = 0.042). The available number of female assistant professors (n = 50) was more than half of the male assistant professors (n = 88), this ratio however, plummeted at higher academic ranks, with only one-fourth of women (n = 11) professors compared to men (n = 45). The male MSK radiologist had 1.31 times the odds of having a higher h-index, keeping all other variables constant. Conclusions: The trend of gender disparity exists in MSK radiology with significant underrepresentation of women in top tiers of academic hierarchy. Even with comparable h-indices, at the lower academic ranks, a lesser number of women are promoted relative to their male colleagues. Further studies are needed to investigate the degree of influence research productivity has, in determining academic advancement of MSK radiologists. © 2017, ISS.

    Background Women physicians continue to comprise the minority of leadership roles in Academic Family Medicine (AFM) faculty across North American medical schools. Our study quantified the current state of gender disparity by analyzing academic position, leadership ranking, and research productivity. Methods We generated a database for 6,746 AFM faculty members. Gender and academic profiles were obtained for 2,892 academic ranks and 1,706 leadership roles by searching faculty listings enlisted in Fellowship and Residency Electronic Interactive Database (FREIDA) and Canadian Resident Matching Service (CaRMS). To measure research productivity, we obtained bibliometric data: h-index, citations, and tenure from 2,383 faculty members using Elsevier's SCOPUS archives. Data analysis and h-index were formulated using Stata version 14.2 (StataCorp LP, College Station, TX). Results Our results indicated that women hold 46.11% (3,110/6,746) of faculty positions. The proportional composition decreased with increasing academic ranking (49.84% assistant, 46.78% associate, and 41.5% full professor). The same decreasing trend was demonstrated with leadership rank (57.14% minor leadership, 47.65% second-in-command, and 36.61 first-in-command). Compared to their gender counterparts, women in AFM demonstrated lower publication productivity as measured by citation number (p=0.04) and years of study (p=0.008). The final prediction equation model after multivariable analyses included gender, publications, citations, country of graduation, and years of active research (p<0.05). Conclusions The composition of academic family medicine faculty members included in this study demonstrated gender disparity. Inclusivity initiatives and policies to tackle the issue of female retention, promotion, and recruitment need to be further explored.

    Many studies demonstrate differences in the coverage of citing publications in Google Scholar (GS) and Web of Science (WoS). Here, we examine to what extent citation data from the two databases reflect the scholarly impact of women and men differently. Our conjecture is that WoS carries an indirect gender bias in its selection criteria for citation sources that GS avoids due to criteria that are more inclusive. Using a sample of 1250 U.S. researchers in Sociology, Political Science, Economics, Cardiology and Chemistry, we examine gender differences in the average citation coverage of the two databases. We also calculate database-specific h-indices for all authors in the sample. In repeated simulations of hiring scenarios, we use these indices to examine whether women's appointment rates increase if hiring decisions rely on data from GS in lieu of WoS. We find no systematic gender differences in the citation coverage of the two databases. Further, our results indicate marginal to non-existing effects of database selection on women's success-rates in the simulations. In line with the existing literature, we find the citation coverage in WoS to be largest in Cardiology and Chemistry and smallest in Political Science and Sociology. The concordance between author-based h-indices measured by GS and WoS is largest for Chemistry followed by Cardiology, Political Science, Sociology and Economics. © 2018 Elsevier Ltd.
