ObjectiveTo assess the prevalence of and factors associated with Burnout syndrome among intensive care unit professionals.MethodsIn this cross-sectional population-based study, a questionnaire assessing sociodemographic, behavioral, and occupational data was administered to 241 nurses and physicians working in 17 public intensive care units in São Luis (MA), Brazil. The Maslach Burnout Inventory - Human Services Survey was used to identify Burnout syndrome based on Maslach's and Grunfeld's criteria. The prevalence of each dimension of the syndrome was estimated with a 95% confidence interval. Associations were estimated by the odds ratios via multiple logistic regression analyses (α = 5%).ResultsThe prevalence of Burnout syndrome was 0.41% (0.01 - 2.29) according to Maslach's criteria and 36.9% (30.82 - 43.36) according to Grunfeld's criteria. Infant intensive care unit professionals were more likely to develop emotional exhaustion than other intensive care professionals (OR = 3.16). Respondents over the age of 35 were less likely to develop emotional exhaustion (OR = 0.32) and depersonalization (OR = 0.06). Longer working hours in intensive care units were associated with a reduced sense of personal accomplishment (OR = 1.13). Among nurses, males had a lower sense of professional accomplishment, and not exercising regularly was associated with more emotional exhaustion and less depersonalization. Among physicians, working in infant and cardiology intensive care units made them less likely to have a reduced sense of personal accomplishment, and physicians without a postgraduate degree who worked in intensive care units had a higher chance of having a lower sense of personal accomplishment.ConclusionThis study demonstrated the low prevalence of Burnout syndrome. Most of the professionals reported low levels for each dimension of Burnout, including low levels of emotional exhaustion, low levels of depersonalization, and a lower likelihood of having a reduced sense of personal accomplishment. Nurses and physicians have different characteristics associated with Burnout syndrome.
