First and last authorship by gender in emergency medicine publications- a comparison of 2008 vs. 2018.

Abstract

Recently, investigators reported that there remain substantial disparities in the proportion of women within emergency medicine (EM) who have achieved promotion to higher academic rankings, received grant funding, and attained departmental leadership positions. In 2007, women were first authors on 24% of EM-based peer-reviewed articles. Currently, 28% of the academic EM physician workforce is comprised of women. The goal of this study was to identify whether the proportion of female first authors of original research published in three U.S.-based EM journals increased in 2018 as compared to 2008. This was a retrospective review of published original research articles during 2008 and 2018 in the journals Academic Emergency Medicine (AEM), American Journal of Emergency Medicine (AJEM), and Annals of Emergency Medicine (Annals). Review articles, opinion pieces, consensus statements, practice recommendations based on current guidelines, and case reports were excluded from analysis. Investigators conducted a review of each article to identify the gender of the study's first and last authors. A study author blinded to the previous author's data abstraction reviewed a sample of 25 articles to assess for inter-rater reliability (kappa). Categorical data are presented as frequency of occurrence and analyzed by chi-square. Overall for the study journals, there were 368 original research articles published in 2008 vs. 580 in 2018. There were no significant differences noted for the proportion of female first author publications during 2008 vs 2018 overall (28% vs 30%; p=0.38), within AJEM (29% vs 28%; p=0.85), and observed at Annals (25% vs 24%; p=0.82) respectively. However, there was a significant increase in the number of first author publications by females between the two periods within AEM (28% vs 45%; p<0.01). There were no significant differences noted for the proportion of female last author publications during 2008 vs. 2018 overall (21% vs 22%; p=0.70) and within each respective journal: AEM 22%% vs 26% (p=0.51), AJEM 22% vs 19% (p=0.55), and Annals 19% vs 22% (p=0.20). Inter-rater reliability for author gender within the sample articles was excellent (0.83). While female physicians make up a disproportionate 28% of the academic workforce, we found that they were proportionally represented as first authors within several of the most prominent U.S.-based EM journals. Female resident physicians remain underrepresented as first authors and women remain underrepresented as last authors in the same journals.
