Automated external defibrillator use in public places: a study of acquisition time.

Abstract：

BACKGROUND:Sudden cardiac arrest (SCA) is a frequent cause of death in the developed world. Early defibrillation, preferably within the first minutes of the incident, significantly increases survival rates. Accessible automated external defibrillators (AED) in public areas have been promoted for many years, and several locations are equipped with these devices. AIM:The aim of the study was to assess the real-life availability of AEDs and assess possible sources of delay. METHODS:The study took place in the academic towns of Poznan, Lodz, and Warsaw, Poland. The researchers who were not aware of the exact location of the AED in the selected public locations had to deliver AED therapy in simulated SCA scenarios. For the purpose of the trial, we assumed that the SCA takes place at the main entrance to the public areas equipped with an AED. RESULTS:From approximately 200 locations that have AEDs, 78 sites were analysed. In most places, the AED was located on the ground floor and the median distance from the site of SCA to the nearest AED point was 15 m (interquartile range [IQR] 7-24; range: 2-163 m). The total time required to deliver the device was 96 s (IQR 52-144 s). The average time for discussion with the person responsible for the AED (security officer, staff, etc.) was 16 s (IQR 0-49). The AED was located in open access cabinets for unrestricted collection in 29 locations; in 10 cases an AED was delivered by the personnel, and in 29 cases AED utilisation required continuous personnel assistance. The mode of accessing the AED device was related to the longer discussion time (p < 0.001); however, this did not cause any significant delay in therapy (p = 0.132). The AED was clearly visible in 34 (43.6%) sites. The visibility of AED did not influence the total time of simulated AED implementation. CONCLUSIONS:We conclude that the access to AED is relatively fast in public places. In the majority of assessed locations, it meets the recommended time to early defibrillation of under 3 min from the onset of the cardiac arrest; however, there are several causes for possible delays. The AED signs indicating the location of the device should be larger. AEDs should also be displayed in unrestricted areas for easy access rather than being kept under staff care or in cabinets.
