The Doris and Howard Hiatt Residency in Global Health Equity and Internal Medicine at Brigham and Women's Hospital provides global health training during residency, but little is known about its effect on participants' selection of a global health career. We assessed the perceptions of residency graduates from the first 7 classes to better understand the outcomes of this education program, and the challenges faced by participants. We interviewed 27 of 31 physicians (87%) who graduated from the program between 2003 and 2013 using a convergent mixed-methods design and a structured interview tool that included both open-ended and forced-choice questions. We independently coded and analyzed qualitative data using a case study design, and then wove together the qualitative and quantitative data at the interpretation phase using a parallel convergent mixed-methods design. Entering a career focused on social justice was cited as the most common motivator for selecting to train in global health. Most respondents (83%, 20 of 24) reported they were able to achieve this goal despite structural barriers, such as lower salaries compared with peers, a lack of mentors in the field, poorly structured and undersupported career pathways at their institutions, and unique work-life challenges. A majority of graduates from 1 dedicated residency program in global health and internal medicine reported they were able to continue to engage in global health activities after graduation and, despite identified challenges, reported that they planned long-term careers in global health.
