Ethics approval and consent to participate
: Formal approval of the institutional ethics committee was not requested. Participants were informed about the anonymized use of the test results and participation was voluntary. All our residents and fellows were informed about this educational program and adjacent study design prior to the start of the study. We gave them the opportunity to object against the use of their test results or data, whenever they wanted.The intervention was part of the educational sessions all residents and fellows attend during their employment at the ICU. We considered the online questionnaire as part of this, therefore we did not consult the ethics committee.
