Rank Equity Index: Measuring Parity in the Advancement of Underrepresented Populations in Academic Medicine

As educators, researchers, clinicians, and administrators, faculty serve pivotal roles in academic medical centers (AMCs). Thus, the quality of faculty members' experiences is inseparable from an AMC's success. In seeking new methods to assess equity in advancement in academic medicine, the authors developed the Rank Equity Index (REI)-adapted from the Executive Parity Index, a scale previously implemented within the business sector-to examine national data on gender and racial/ethnic equity across faculty ranks. The REI was employed on self-reported demographic data, collected by the Association of American Medical Colleges, from U.S. medical school faculty in 2017, to make pairwise rank comparisons of the professoriate by demographic characteristics and department. Overall results indicated that women did not attain parity at any pairwise rank comparison, while men were above parity at all ranks. Similar results were observed across all departments surveyed: women in the basic sciences had REIs closest to parity, women in pediatrics had the highest representation but had REIs that were further from parity than REIs in the basic sciences, and women in surgery demonstrated the lowest REIs. Nationally, REIs were below 1.00 for all racial/ethnic group rank comparisons except for White and, in one case, multiple-race non-Hispanic/Latinx. Across all analyzed departments, Black/African American, Asian, Hispanic/Latinx, and multiple-race Hispanic/Latinx faculty had REIs below parity at all ranks except in 2 cases. In a comparison of 2017 and 2007 data, REIs across both race/ethnicity and gender were lower in 2007 for nearly all groups. REI analyses can highlight inequities in faculty rank that may be masked when using aggregate faculty proportions, which do not account for rank. The REI provides AMCs with a new tool to better analyze institutional data to inform efforts to increase parity across all faculty ranks.
