Nursing burnout is characterized by emotional exhaustion, depersonalization, and a low sense of personal accomplishment. It develops as a response to chronic emotional strain from caring for patients with serious problems. Nurses are especially susceptible due to the emotional demands of their profession. Burnout leads to deteriorated relationships and increased absenteeism and turnover among nurses, negatively impacting patient care. Contributing factors include the time spent caring for patients, workload, lack of support, and personality traits influencing stress resistance.
