University of Pennsylvania researchers have found that notable progress has not happened since 2009, when the Liaison Committee on Medical Education set forth new diversity accreditation guidelines. This is particularly true for Black, Hispanic and American Indian/Native Alaskan (AIAN) physicians. Absolute numbers of Black, Hispanic and AIAN physicians have increased but so have the number of all physicians. Therefore, the percentage of physicians in underrepresented groups has not increased appreciably. Read the Fortune magazine article or check out the research on JAMA Network Open.
