Abstract
The coronavirus disease 2019 (COVID-19) pandemic has served as a stark reminder of the importance of foundational public health training for all physicians. However, the most effective way to incorporate these concepts into undergraduate medical education remains unclear. Here, we characterize the literature regarding the effectiveness of public health integration into undergraduate medical education in North America. We systematically searched MEDLINE, Embase, Cochrane Central, and Education Resources Information Center (ERIC) in accordance with preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines for North American peer-reviewed literature, published from 01/01/2000 to 30/08/2021, that described outcomes of integrating public health training within an undergraduate medical curriculum. Results were qualitatively synthesized into key themes. A total of 38 studies, involving interventions across 43 medical schools, were included. Studies reported on a combination of public (n=13), global (n=9), population (n=9), community (n=6), and epidemiological (n=1) health interventions, and either implemented one-off workshops, electives, or international experiences (n=19); a longitudinal theme or long-term enrichment pathway (n=14); or a case-based learning curriculum (n=8). The majority (81.5%, 31/38) of integrations were self-described as successful and, of studies reporting on feasibility, most (94.1%, 16/17) were indicated as feasible. The definition of what constituted such success, however, was unclear. Innovative examples included the use of simulation workshops and mobile-optimized media content. Key challenges were noted, however, in securing adequate funding and buy-in from administrative leadership. Robust community partnerships and iterative cycles of implementation of the intervention were critical factors to success. In summary, foundational public health components can be effectively integrated into medical school curricula and would benefit from adequate resourcing, innovation, community partnerships, and continuous improvement.
