The prevalence of burnout is much higher in physicians than in other occupations. Academic physicians serve important functions, training future physicians and advancing medical research in addition to doing clinical work. However, they are particularly vulnerable to burnout for reasons including low compensation for teaching, pressure to publish despite a lack of time and declining research funds, and a redistribution of clinical workload due to restrictions on trainee work hours. Junior faculty, women, and marginalized groups are the most affected. Beyond poor physician health and worse patient outcomes, burnout is strongly associated with reduced work effort and an intent to leave the profession. Moreover, physicians are leaving the workforce in record numbers, further increasing the stress on remaining physicians. Combined with a worsening of quality of patient care, this increased rate of physician burnout threatens the viability of health care organizations. This review discusses the causes and consequences of faculty burnout, as well as interventions undertaken for its mitigation.
