Limitation
ROSC
A simulation can only try to reproduce the care practice as best as possible. Yet, a deviation from reality remains, and therefore, certain findings cannot be intuitively ascertained but require an inquiry. The study participants in both groups rated the realism of the scenario design as high. To allow a reproducible study performance, the supply time was limited to 10 min in both groups. This time interval is realistic for the prehospital setting before transport measures are undertaken. The teams (provider) were not involved in creating the design and content of the checklist. The checklist was only demonstrated as a concept in a short lecture to the participants. The medical content of the checklist (ROSC) was not taught; therefore, the findings of this study must be described as a minimal possible effect of checklist use. In reality, a structured implementation of the checklist with a detailed team training is recommended to maximize the benefit.The medical guideline referred to in the study is outdated. Valid guidelines reprioritized the relevance of TTM. Since the study had the focus on checklist use and not the medical content of the checklist results of the study are not diminished.
