Burnout is a pervasive and alarming issue for physicians-in-training (residents), as well as practicing physicians, with significant consequences for resident well-being, care quality, and patient safety. Efforts to address burnout have emphasized both organization-level factors that create more supportive environments and individual-level factors that enhance physician resilience in the face of challenges. However, residents primarily work in teams – delivering patient care with fellow trainees, faculty and interprofessional colleagues. Team practices and behaviors have been found to impact how individuals experience their work – yet, the relationship of these team-level factors to resident burnout is still largely unknown.
