Burnout, resilience, and the cost of learning in medical students: A scoping review informed by professional identity formation theory

Introduction Medical students routinely encounter emotionally and ethically demanding clinical situations that shape, and sometimes strain, their developing professional identities. This review extends the cost of caring constructs in clinicians to conceptualize the cost of learning in students and examine how it interacts with burnout, resilience, and grit within professional identity formation (PIF).Methods Using a theory-informed scoping review design and a constructivist, relativist lens, five databases (PubMed, Embase, Scopus, ERIC, and PsycINFO) were searched for English-language articles on medical students published between 1 January 2000 and 4 November 2024. The modified Systematic Evidence-Based Approach combined systematic searching, parallel thematic and directed content analyses, and AI-assisted coding. The Ring Theory of Personhood (RToP) provided the analytic lens for an interpretive synthesis examining how all these elements interact within PIF.Results Of 11,994 abstracts identified, 387 full-text articles were reviewed, and 63 studies met the inclusion criteria. Across studies, elements of the cost of learning, including moral distress, compassion fatigue, vicarious trauma, secondary traumatic stress, and associated cognitive, emotional, and psychosomatic sequelae, extended beyond core burnout components. Resilience was predominantly conceptualized as an individual trait inversely associated with burnout, though some studies highlighted relational and institutional determinants. Mapping the findings to the RToP indicated that the cost of learning and resilience operate across the Individual, Relational, and Societal Rings, while constructs associated with the Innate Ring were largely absent.Discussion Burnout in medical students is better understood as a signal that PIF is under strain than as an isolated symptom cluster. Here, the internal compass refers to the evolving sense of values, purpose, and professional self through which students make meaning of demanding clinical encounters and integrate them into a coherent identity. Supporting this internal compass requires coordinated strategies across the Innate, Individual, Relational, and Societal Rings of Personhood, implemented through curriculum, institutional structures, and faculty development. Practice pointsBurnout in medical students signals disrupted professional identity formation rather than an isolated symptom cluster; identifying a student experiencing burnout should prompt an upstream inquiry into the individual, relational, and institutional conditions that contributed to it.The cost of learning—comprising moral distress, compassion fatigue, vicarious trauma, and secondary traumatic stress—cannot be eliminated from clinical training but can be navigated more effectively when students are equipped with reflective and adaptive capacities developed through intentional curricular investment.Resilience develops through relational and institutional conditions, including longitudinal mentoring, peer networks that normalize distress, and psychologically safe learning environments; it cannot be adequately cultivated through individual-level interventions alone.Structured opportunities for students to reflect on meaning, purpose, and core values are a fundamental curricular investment in professional identity formation, not an optional enrichment activity.Faculty development is a precondition for effective implementation; educators who can navigate their own cost of caring are better positioned to support students in navigating theirs.
