Abstract 14999: Functional Assessment of Community-Based Automated External Defibrillators
Introduction: The use of automated external defibrillators (AEDs) coupled with bystander CPR has been shown to significantly improve mortality for out-of-hospital cardiac arrest. However, ongoing maintenance of community-based devices is largely unregulated and the true risk for device failure is unknown. We sought to characterize AED functionality across a spectrum of community-based sites to better understand the risk of potential AED malfunction.
Methods: This study consisted of an on-site assessment of community-based AEDs by investigators. A community-based site was defined as a public, non-health related setting. AED location, registration, and component recalls were recorded when available. Each AED was tested according to the maintenance guidelines for the device manufacturer. Appropriate functionality for an AED was defined as having good pads and batteries, no outstanding recalls, and completing the self-test.
Results: A total of 108 AEDs at 85 unique sites were surveyed. Every site surveyed reported having employees or staff trained at the time of AED implementation. However, of 108 surveyed AEDs, 36 (33%) failed testing. Of the 36 AEDs with documented problems, 34 had expired pads and 12 (11%) had expired batteries. Each of those 12 failed to power on, representing a potential life threatening failure. AEDs were found in a variety of community settings, represented in Table 1. In our sample, improperly functioning AEDs were more likely to be found on college campuses than in other community settings. Only one of the sampled AEDs was registered nationally, while 22 were registered locally.
Conclusions: The percentage of community-based AEDs that fail testing is high, and the incidence of potentially life-threatening malfunction likely underreported. Based upon the results, we believe campaigns to enhance awareness and perhaps mandatory local AED registration and maintenance regulations should be considered.
