Equity, Diversity, and Inclusion in Radiation Oncology: A Bibliometric Analysis and Critical Review

Abstract

The promotion of equity, diversity, and inclusion (EDI) is being increasingly pursued in health care, both in general and within radiation oncology. Because bibliometrics is a powerful tool to reveal the scientific literature on a specific topic during a certain timespan, a systematic bibliometric analysis of the documents published on EDI in radiation oncology was performed, aiming at exploring common patterns in research and emerging trends, tracking collaborations and networks, and anticipating future directions in clinical research. Standard descriptive statistics and bibliometric techniques were used in the analysis. A collaboration network and thematic map were generated from the data. Four domains were represented: (1) motor themes, including themes well developed and important for the structuring of the research field; (2) niche themes, representing the isolated topics that do not share important external links with other themes; (3) emerging themes, referring to still weakly developed topics; and (4) basic themes, including the essential topics. EDI in the profession of radiation oncology is essential to ensure that the workforce delivering radiation oncology care both draws from the full talent pool of human capital and delivers the highest quality science and clinical care to all patients. The burgeoning literature on EDI in radiation oncology suggests that a large and growing cohort of scholars within radiation oncology are dedicated to addressing these important challenges.
