BackgroundEnd-of-life care (EOLC) in the intensive care unit (ICU) is becoming increasingly more common but ethical standards are compromised by growing economic pressure. It was previously found that perception of non-beneficial treatment (NBT) was independently associated with the core burnout dimension of emotional exhaustion. It is unknown whether factors of the work environment also play a role in the context of EOLC.ObjectiveIs the working environment associated with perception of NBT or clinician burnout?Material And MethodsPhysicians and nursing personnel from 11 German ICUs who took part in an international, longitudinal prospective observational study on EOLC in 2015-2016 were surveyed using validated instruments. Risk factors were obtained by multivariate multilevel analysis.ResultsThe participation rate was 49.8% of personnel working in the ICU at the time of the survey. Overall, 325 nursing personnel, 91 residents and 26 consulting physicians participated. Nurses perceived NBT more frequently than physicians. Predictors for the perception of NBT were profession, collaboration in the EOLC context, excessively high workload (each p ≤ 0.001) and the numbers of weekend working days per month (p = 0.012). Protective factors against burnout included intensive care specialization (p = 0.001) and emotional support within the team (p ≤ 0.001), while emotional exhaustion through contact with relatives at the end of life and a high workload were both increased (each p ≤ 0.001).DiscussionUsing the example of EOLC, deficits in the work environment and stress factors were uncovered. Factors of the work environment are associated with perceived NBT. To reduce NBT and burnout, the quality of the work environment should be improved and intensive care specialization and emotional support within the team enhanced. Interprofessional decision-making among the ICU team and interprofessional collaboration should be improved by regular joint rounds and interprofessional case discussions. Mitigating stressful factors such as communication with relatives and high workload require allocation of respective resources.
