Popis: Introduction: High density of citizen responders (CR) and automated external defibrillators (AEDs) may increase chances for early bystander defibrillation in out-of-hospital cardiac arrest (OHCA). We aimed to assess coverage using current CR and AED positions applied on historical OHCAs in Denmark. Methods: Non-EMS witnessed OHCAs from the Danish cardiac arrest registry with known location (2016-2019) and AEDs registered with the Danish AED network (November 2020) were included. Locations of all CRs registered with the national CR program were identified (Wed, December 2, 2020) at 12pm (noon) and 12am (midnight). Since pilot data showed 25% of alerted CRs accepted the alarm, we investigated OHCA CR coverage defined ≥4 CR within Results: A total of 18,128 OHCAs (median age 73 years, 63.4% male) were included. A total of 22,418 AEDs (386/100,000 inhabitants) were available at 12pm, 65% were accessible 24/7. A total of 34,033 CR (586 CR/100,000 inhabitants) were available at 12am and 33,938 were available at12pm. During daytime, a median of 29 AEDs and 37 CRs were Conclusion: Following the implementation of a nationwide AED network and a citizen responder program, most historical OHCAs (85%) were < 1800m of CRs and AEDs at midnight with a slight decrease during daytime (82%). A decrease in CR and AED coverage were observed for 500m (59%) and 200 m (14%), with little difference according to time of day. During daytime a median of 29 AEDs and 37 CRs were < 1800m of historical OHCAs. Our results indicate successful implementation of a national AED registry and CR program with great potential for improving bystander defibrillation.
