Background Little is known about whether cardiopulmonary resuscitation ( CPR ) training can increase bystander CPR in the community or the appropriate target number of CPR trainings. Herein, we aimed to demonstrate community-wide aggressive dissemination of CPR training and evaluate temporal trends in bystander CPR. Methods and Results We provided CPR training (45-minute chest compression-only CPR plus automated external defibrillator use training or the conventional CPR training), targeting 16% of residents. ⋯ The 1-year increment was associated with high-quality bystander CPR (adjusted odds ratio, 1.461; 95% CI, 1.055-2.024). Bystanders who previously experienced CPR training were 3.432 times (95% CI, 1.170-10.071) more likely to perform high-quality CPR than those who did not. Conclusions We trained 23.0% of the residents in the medium-sized city of Osaka, Japan, and demonstrated that the proportion of high-quality CPR performed on the scene increased gradually, whereas that of bystander CPR delivered overall remained stable.

Sex Differences in Receiving Layperson Cardiopulmonary Resuscitation in Pediatric Out-of-Hospital Cardiac Arrest: A Nationwide Cohort Study in Japan.
Background Layperson cardiopulmonary resuscitation ( CPR ) is a crucial intervention for patients with out-of-hospital cardiac arrest ( OHCA ). Although a sex disparity in receiving layperson CPR (ie, female patients were less likely to receive layperson CPR ) has been reported in adults, there are few data in the pediatric population, and we therefore investigated sex differences in receiving layperson CPR in pediatric patients with OHCA. Methods and Results From the All-Japan Utstein Registry, a prospective, nationwide, population-based OHCA database, we included pediatric patients (≤17 years) with layperson-witnessed OHCA from 2005 through 2015. ⋯ After adjustment for age, time of day of arrest, year, witnesses persons, and dispatcher CPR instruction, the sex difference in receiving layperson CPR was not significant (adjusted odds ratio for female subjects 1.14, 95% CI, 0.996-1.31). Conclusions In a pediatric population, female patients with layperson-witnessed OHCA received layperson CPR more often than male patients. After adjustment for covariates, there was no significant association between patient sex and receiving layperson CPR .
