Abstract
Background
Actual application of public-access automated external defibrillator (AED) pads to
patients with an out-of-hospital cardiac arrest (OHCA) by the public has been poorly
investigated.
Methods
AED applications, prehospital characteristics, and one-month outcomes of OHCAs occurring
in Osaka Prefecture from 2011 to 2012 were obtained from the Utstein Osaka Project
registry. Patients with a non-traumatic OHCA occurring before emergency medical service
attendance were enrolled. The proportion of AED pads that were applied to the patients’
chests by the public and one-month outcomes were analysed according to the location
of OHCA.
Results
In total, public-access AED pads were applied to 3.5% of OHCA patients (351/9978)
during the study period. In the multivariate analyses, OHCAs that occurred in public
places and received bystander-initiated cardiopulmonary resuscitation were associated
with significantly higher application of public-access AEDs. Among the patients for
whom public-access AED pads were applied, 29.6% (104/351) received public-access defibrillation.
One-month survival with a favourable neurological outcome was significantly higher
among patients who had an AED applied compared to those who did not (19.4% vs. 3.0%;
OR: 2.76 [95% CI: 1.92–3.97]).
Conclusion
The application of public-access AEDs leads to favourable outcomes after an OHCA,
but utilisation of available equipment remains insufficient, and varies considerably
according to the location of the OHCA event. Alongside disseminating public-access
AEDs, further strategic approaches for the deployment of AEDs at the scene, as well
as basic life support training for the public are required to improve survival rates
after OHCAs.
