NCT05583084

Brief Summary

The goal of this observational study is to investigate characteristics in out-of-hospital cardiac arrests (OHCA) related to sex differences. The main questions it aims to answer are:

  • are there possible differences in help provision by bystanders, cardiopulmonary resuscitation (CPR), pre-hospital treatment by emergency medical services (EMS)?
  • are there differences in the presence of shockable initial rhythm (SIR) and survival rates after OHCA at successive stages of treatment? Researchers will compare all emergency medical services treated resuscitations in Denmark between 2016 and 2021 to see if there are possible differences between sexes.
