A 25-Year Analysis of Diversity, Equity, and Inclusion Research in Orthopaedics Shows Majority Female Authorship and Increasing Gender Parity Research

INTRODUCTION: Orthopaedic surgery is one of the least diverse fields in medicine. In recent decades, there has been a concerted effort to increase diversity, equity, and inclusion (DEI) in the specialty, in addition to the institution of several organizations to establish the pipeline and facilitate underrepresented minority students into orthopaedic surgery. The aim of this study was to examine trends in orthopaedic surgery DEI research. METHODS: A search of DEI articles was conducted in orthopaedic surgery using PubMed, MEDLINE, EMBASE, Scopus, Cumulative Index to Nursing and Allied Health Literature, and Education Resources Information Center. The year of publication, article topic of focus, sex of the primary author, publishing journal, citation index, and primary contributing institution were recorded for each article. Sex of the primary author was predicted by the authors using an online image search of the author and institution. Articles were excluded if the research was conducted outside of the United States or if they were not specific to orthopaedic surgery. RESULTS: A total of 143 articles met the inclusion criteria. A total of 52.4% of authors (n = 75) were women and 44.1% (n = 63) were men. A total of 42.7% of the articles were written about sex (n = 61), 39.9% about race/ethnicity and sex (n = 57), and 11.9% about race/ethnicity (n = 17). A total of 10 articles were affiliated with Washington University in St. Louis while 51 other institutions wrote the remaining articles, with none having more than 4. Information could not be confirmed for 5 articles. In 2018, 5 articles were published, followed by 17 in 2019, 25 in 2020, 34 in 2021, and 30 in 2022. CONCLUSION: DEI research in orthopaedic surgery is a relatively new venture within the specialty and has room to grow, specifically in the examination of race/ethnicity and inclusion strategies. Leading journals and academic institutions in orthopaedic surgery should incentivize productivity and authorship in DEI research. LEVEL OF EVIDENCE: III.
