Minnesota Heart Safe Communities: Are community-based initiatives increasing pre-ambulance CPR and AED use?

Implementation research that describes how successfully resuscitation guidelines are translated into practice are lacking. We examined whether recent community-based initiatives being conducted as part of the Minnesota Heart Safe (HS) Communities program increase the delivery of CPR and use of automated external defibrillators (AED) by bystanders and first responders prior to ambulance arrival. Methods Non-EMS witnessed out-of-hospital cardiac arrests (OHCA) with presumed cardiac etiology treated by a single ambulance service in 2013–2015 were studied. Data were obtained from the Minnesota HS program and the Cardiac Arrest Registry to Enhance Survival (CARES) Surveillance Registry. Pre-ambulance CPR and AED use within HS communities before and after completion of the program were compared. Results As of July 2016, 17 Minnesota communities within the ambulance service area had achieved HS designation and 294 OHCAs that occurred in these communities met inclusion criteria for analysis (120 before HS designation, 174 after). CPR was initiated by bystanders or first responders prior to ambulance arrival in 83% of OHCA events that occurred before HS designation and in 95% of events that occurred after designation (OR=4.23 [1.80–9.98]). Pre-ambulance AED use increased from 63% to 77% after the community intervention (OR=1.94 [1.16–3.24]). Overall unadjusted survival to hospital discharge increased slightly after HS designation, but this difference was not statistically significant (17% vs 20%, p=0.32). Conclusion Implementation of the Heart Safe program in communities within our ambulance service area in Minnesota has increased use of CPR and AEDs by bystanders and first responders prior to ambulance arrival.
