Finally, 1813 intensivists participated in the survey. The participation rate was 90.7%. The prevalence of burnout and severe burnout was 82.1% (1489/1813) and 38.8% (704/1813), respectively. According to the logistic regressionanalysis, "difficulty in making treatment decisions" was independently associated with burnout [OR = 1.365, CI (1.060, 1.757)]. "Higher number of children" [OR = 0.714, CI (0.519, 0.981)] and higher "incomesatisfaction" [OR = 0.771, CI (0.619, 0.959)] were independent protective factors against severe burnout.
