Female authorship trends in the field of colorectal surgery: A retrospective bibliometric study

BACKGROUND: Gender disparity and hidden discrimination remained in the surgical subspecialties. This study aimed to explore the authorship gender composition in four high-impact colorectal surgery journals over the past two decades. METHOD: This cross-sectional study queried the Web of Science Core Collection database and PubMed (MEDLINE) for articles published in four high-impact colorectal surgery specialty journals between 2000 and 2021 (Database accessed at July 2022). Extracted data included authors' full names, institutions, year of publication and total citation numbers. Authors’ genders were assigned via gendrize.io, a third-party name predictor tool. RESULTS: 100,325 authorship records were included in the final analysis. 21.8% of writers were identified as female, an increase from 11.4% (95% CI, 9.4%–13.3%) in 2000 to 26.5% (95% CI, 25.6%–27.4%) in 2021. Female authorship has risen in all authorship types, but women physicians were less likely to be the last authors than the first (OR, 0.63; 95%CI, 0.6–0.67) or middle authors (OR, 0.57; 95%CI, 0.55–0.60). Female authorship has also increased substantially in different document types, but female authorships were less likely in editorials than original articles (OR, 0.76; 95%CI, 0.7–0.83) and reviews (OR, 0.83; 95%CI, 0.74–0.94). Compared with male physicians, females were more likely to author in publications with reportable funding, either as first authors (OR, 1.46; 95%CI, 1.12–1.78) or last authors (OR, 1.51; 95%CI, 1.22–1.89). Authorship varied geographically, and countries with the highest female authorship percentage were mainly in Europe and North America. CONCLUSION: Female authorship has grown substantially in colorectal surgery literature. However, female physicians were still underrepresented and less likely to assume senior or leading authorship roles.
