Brief Summary

Neither the international nor the interregional variation in survival following OHCA is fully understood, but may rely on multiple factors such as: organization of the Emergency Medical Service (EMS) system bystander cardiopulmonary resuscitation (CPR), the use of Automatic External Defibrillators (AED's), response time, and which subgroups are included as the denominator, (i.e. obvious dead, withholding of resuscitation). Variation in denominators provide an obstacle when comparing outcome between different EMS-systems. Studies have found that Utstein factors explained half of the variation in survival to hospital discharge among different EMS agencies highlighting the importance of further research. Due to the high mortality rate of OHCA, the decision of withholding or withdrawing resuscitative efforts must be made frequently. We find that a description of the differences in initiation and termination of resuscitation of adult patients (\>18 years of age), suffering from non-traumatic OHCA could add an important perspective on the impact of differences in EMS systems across the World regarding the outcome following OHCA.
