The impact of underrepresented minority or marginalized identity status on training outcomes of MD-PhD students

Dual-degree MD-PhD programs have historically lacked diversity of race, ethnicity, gender, sexual orientation, and other facets of identity. Like MD- and PhD-granting programs, MD-PhD program training environments are also marked by structural barriers that negatively impact measurable academic outcomes of underrepresented and/or marginalized students in academic medicine (racial and ethnic minority groups considered underrepresented by the National Institute of Health, sexual and gender minorities, individuals with disabilities, and individuals of low socioeconomic status). In this article, we review the existing literature on MD-PhD program disparities affecting students from these groups and provide recommendations grounded on the reviewed evidence. Our literature review identified four generalizable barriers that can impact the training outcomes of students from these marginalized and/or underrepresented groups: 1) discrimination and bias, 2) impostor syndrome and stereotype threat, 3) lack of identity-similar mentors, and 4) suboptimal institutional policies and procedures. We propose goal-oriented interventions that may begin to ameliorate the disparities present in MD-PhD program training environments that affect students from marginalized and/or underrepresented groups in academic medicine.
