Out-of-Hospital Cardiac Arrest Locations in a Rural Community: Where Should We Place AEDs?

Abstract

AbstractEarly defibrillation improves survival for patients suffering cardiac arrest from ventricular fibrillation (VF) or ventricular tachycardia (VT). Automated external defibrillators (AEDs) should be placed in locations in which there is a high incidence of out-of-hospital cardiac arrest (OOHCA). The study objective was to identify high-risk, rural locations that might benefit from AED placement. A retrospective review of OOHCA in a rural community during the past 5.5 years was conducted. The OOHCAs that occurred in non-residential areas were categorized based on location. Nine hundred, forty OOHCAs occurred during the study period of which 265 (28.2%) happened in non-residential areas. Of these, 127 (47.9%) occurred in healthcare-related locations, including 104 (39.2%) in extended care facilities. No location used in this study had more than two OOHCAs. Most (52.1%) non-residential OOHCAs occurred as isolated events in 146 different locations. Almost half of the OOHCAs that occurred in non-residential areas took place in healthcare-related facilities suggesting that patients at these locations may benefit from AED placement. First responders with AEDs are likely to have the greatest impact in a rural community.
