Does management by community volunteers with AED-only training improve survival in out-of-hospital cardiac arrest compared to standard EMS?
A community-based AED-only training program for volunteers significantly improved survival rates and neurological outcomes for out-of-hospital cardiac arrest compared to standard EMS response.
Absolute Event Rate: 46.2% vs 2.9%
Abstract Out-of-hospital cardiac arrest (OHCA) is a significant public health challenge. Early defibrillation is crucial to manage fatal arrhythmias. The use of automated external defibrillators (AEDs) is a promising tool in enhancing survival. Progetto Vita (PV) in our city pioneered the first community-based AED project in Europe. We present survival data spanning 23 years for all OHCA cases. A total of 6996 OHCAs were recorded. Among these, 156 case were managed by PV volunteers (PV-group). The PV-group managed a significantly higher proportion of shockable rhythms than the EMS group (69.9% vs. 10.9%). Mean time to arrival was shorter (5.7 vs. 10.2 minutes), and survival rates better (46.2% vs. 2.9%, overall). Survival rates declined with time. However, a higher proportion of patients in the PV-group demonstrated favorable neurological outcomes, even up to 9 minutes from the call. Over the study period, the increasing number of AEDs in fixed public places coincided with a substantial rise in ventricular fibrillation survival in the PV-group patients (22% for 2003–2012 to 73% for 2013–2022, p0.001). Table 2 shows independent predictors of survival. In conclusion our simplified AED-focused training has shown higher survival rates and emerges as a highly successful strategy in a small city.Figure 1 Independent predictors of survival
Aschieri et al. (Sat,) conducted a cohort in Out-of-hospital cardiac arrest (OHCA) (n=6,996). Management by PV volunteers (community-based AED project) vs. EMS group was evaluated on Overall survival. Management of out-of-hospital cardiac arrest by community volunteers with AED-only training was associated with higher overall survival compared to standard EMS (46.2% vs. 2.9%).
