Burnout is a psychological syndrome involving prolonged stress that can occur in health care professionals. It is characterized by emotional exhaustion, depersonalization, and reduced personal accomplishment. Nurses experience higher rates of burnout than other health care workers due to stressful work environments like critical care units. Risk factors include high workload, lack of support, and personal characteristics. Left unchecked, burnout can negatively impact health and job performance. Treatment involves reducing stressors through organizational changes, developing coping strategies, and psychotherapy.
