Almost half of critical care physicians report symptoms of severe burnout associated with their ICU work, according to a report and "call to action" from the Critical Care Societies Collaborative (CCSC). Symptoms of severe burnout were highest among pediatric critical care specialists, while 45% of intensivists caring for adults acknowledged severe burnout. Burnout symptoms include exhaustion, depersonalization, and low feelings of personal accomplishment. Almost 90% of ICU nurses had at least one burnout symptom. With 10,000 critical care physicians and 500,000 critical care nurses in the U.S. at risk for burnout, policymakers and health administrators should give the issue high priority, the collaborative argued in its report. The Critical Care Societies Collaborative (CCSC) includes the major professional societies in critical care: the American Thoracic Society, the American College of Chest Physicians, the Society of Critical Care Medicine, and the American Association of Critical-Care Nurses (AACN). The collaborative simultaneously published the ICU burnout report in all four societies' journals.
