Outline of Final Research Achievements

The aim of this study conducted multiphasic analyses on factors associated with the effective use of public-access automated external defibrillations (AEDs) as well as the quality of cardiopulmonary resuscitation (CPR). We collected approximately 56000 OHCA patients in Osaka Prefecture, Japan between 2005 and 2012. Public-access AED pads were applied to 3.5% of OHCA patients (351/9978) between 2011 and 2012. Arrests in public places, witness by bystanders, and bystander-initiated CPR were significantly associated with high proportion of public-access AED pad application. Between 2005 and 2012, the chest compression-only CPR (CCCPR) instruction group received bystander CPR more frequently than conventional CPR instruction group (70.0% versus 62.1%, p<0.001). In the multivariable analysis, CCCPR dispatcher instruction was significantly associated with provision of bystander CPR compared with conventional CPR instruction (adjusted odds ratio 1.44, 95% CI 1.34-1.55).
