Cardiac arrest & resuscitation
Do not attempt resuscitation orders at out-of-hospital cardiac arrest in Denmark
Authors' conclusion
Between 2016 and 2023, in Denmark, there has been a significant increasing trend in the number of OHCAs treated despite DNAR orders. DNAR orders were most frequently observed among older patients, and the prevalence increased progressively with age. National OHCA survival rates are somewhat underestimated, as the inclusion of patients with DNAR orders lowers the reported figures; excluding these cases would yield higher survival estimates.
