Public location and survival from out-of-hospital cardiac arrest in the public-access defibrillation era in Japan.

摘要: Abstract Background The use of public-access automated external defibrillators (AEDs) has become common in Japan. To provide a strategy for appropriate AED deployment, we assessed defibrillation (PAD) by laypersons and the outcomes following out-of-hospital cardiac arrest (OHCA) among adult patients location arrest. Methods From nationwide, prospective, population-based registry after OHCA Japan, enrolled with bystander-witnessed medical origin public locations between 2013 2015. primary outcome measure was one-month favorable neurological defined cerebral performance category 1 or 2. Factors associated ventricular fibrillation (VF) were multivariable logistic regression analysis. Results A total 20,970 OHCAs occurred locations. Of those, proportions PAD were: 13.1% (757/5761) areas, 15.9% (333/2089) at workplaces, 26.0% (544/2095) recreation/sports 36.1% (112/310) educational institutions, 5.8% (241/4151) on streets/highways. In analysis VF arrests, both bystander cardiopulmonary resuscitation [adjusted odds ratio (AOR), 1.78; 95% confidence interval (CI), 1.54–2.07] (AOR, 2.33; CI, 2.05–2.66), emergency service (EMS) response time 0.89; 0.87–0.90) improved outcomes. Earlier initiated bystanders before EMS arrival also better OHCA. Conclusions where AEDs are well-disseminated, program worked effectively occurring Notably, differed substantially according to specific
