The Chief Residency in U.S. and Canadian Graduate Medical Education: A Scoping Review.

PHENOMENON:Despite the nearly universal presence of chief residents within U.S. and Canadian residency programs and their critical importance in graduate medical education, to our knowledge, a comprehensive synthesis of publications about chief residency does not exist. An understanding of the current state of the literature can be helpful to program leadership to make evidence-based improvements to the chief residency and for medical education researchers to recognize and fill gaps in the literature. APPROACH:We performed a scoping review of the literature about chief residency. We searched OVID Medline, PsycINFO, ERIC, and Web of Science databases through January 2023 for publications about chief residency. We included publications addressing chief residency in ACGME specialties in the U.S. and Canada and only those using the term "chief resident" to refer to additional responsibilities beyond the typical residency training. We excluded publications using chief residents as a convenience sample. We performed a topic analysis to identify common topics among studies. FINDINGS:We identified 2,064 publications. We performed title and abstract screening on 1,306 and full text review on 208, resulting in 146 included studies. Roughly half of the publications represented the specialties of Internal Medicine (n = 37, 25.3%) and Psychiatry (n = 30, 20.5%). Topic analysis revealed six major topics: (1) selection of chief residents (2) qualities of chief residents (3) training of chief residents (4) roles of chief residents (5) benefits/challenges of chief residency (6) outcomes after chief residency. INSIGHTS:After reviewing our topic analysis, we identified three key areas warranting increased attention with opportunity for future study: (1) addressing equity and bias in chief resident selection (2) establishment of structured expectations, mentorship, and training of chief residents and (3) increased attention to chief resident experience and career development, including potential downsides of the role.
