The influence on applying the ABCDE-Approach using the a validated score by Peran et al 2020 (ABCDE cognitive aid tool in patient assessment -development and validation in a multicenter pilot simulation study. BMC Emerg Med. 2020;20(1)) and non technical skills using a validated score by Kim et al 2009 (Kim J, Neilipovitz D, Cardinal P, Chiu M.A comparison of global rating scale and checklist scores in the validation of an evaluation tool to assess performance in the resuscitation of critically ill patients during simulated emergencies (abbreviated as "CRM simulator study IB"). Simul Healthc. 2009;4(1):6-16)
2. The influence on the cource on the self- and external assessement of the participants using school marks
3. The influence on the professional safety using a web based survey in a longitudinal modality throughout the entire qualification curriculum of prehospital emergency medicine.
