Background: Little is known about how to effectively increase bystander cardiopulmonary resuscitation (CPR), so we evaluated the 10-year trend of the proportion of bystander CPR in an area with wide dissemination of chest compression-only CPR (CCCPR) training combined with conventional CPR training.Methods and Results: We conducted a descriptive study after a community intervention, using a prospective cohort from September 2010 to December 2019. The intervention consisted of disseminating CCCPR training combined with conventional CPR training in Toyonaka City since 2010. We analyzed all non-traumatic out-of-hospital cardiac arrest (OHCA) patients resuscitated by emergency medical service personnel. The primary outcome was the trend of the proportion of bystander CPR. We conducted multivariate logistic regression models and assessed the adjusted odds ratio (AOR) using a 95% confidence interval (CI) to determine bystander CPR trends. Since 2010, we have trained 168,053 inhabitants (41.9% of the total population of Toyonaka City). A total of 1,508 OHCA patients were included in the analysis. The proportion of bystander CPR did not change from 2010 (43.3%) to 2019 (40.0%; 1-year incremental AOR 1.02 [95% CI: 0.98–1.05]).Conclusions: The proportion of bystander CPR did not increase even after wider dissemination of CPR training. In addition to continuing wider dissemination of CPR training, other strategies such as the use of technology are necessary to increase bystander CPR.

Background:Although bystanders’ performance is important to improve outcomes of patients after cardiac arrests, few studies have investigated the barriers of bystanders, including those who could not perform cardiopulmonary resuscitation or any other rescue actions in emergency situations. This study aimed to assess the relationship between the psychological barriers of laypersons who encountered emergency situations and their rescue actions.Methods and Results:A questionnaire survey was conducted and this included laypersons who had encountered emergency situations during the last 5 years. Six questions were about the psychological barriers and 8 questions were about the laypersons’ rescue actions. The primary outcome was any rescue actions performed by laypersons in an actual emergency situation. Overall, 7,827 (92.8%) of 8,430 laypersons responded; of them, 1,361 (16.1%) had encountered emergency situations during the last 5 years, and 1,220 (14.5%) were eligible for inclusion in the analyses. Of the 6 psychological barriers, “fear of approaching a collapsed person” (adjusted odds ratio [AOR] 0.50; 95% confidence interval [95% CI] 0.32–0.79) and “difficulties in judging whether to perform any rescue action” (AOR 0.63; 95% CI 0.40–0.99) were significantly associated with performing any rescue actions.Conclusions:The fear of approaching a collapsed person and difficulties in judging whether to take any actions were identified as the psychological barriers in performing any rescue actions by laypersons who encountered emergency situations.

Background: Outcomes after out-of-hospital cardiac arrests (OHCAs) might be worse during academic meetings because many medical professionals attend them.Methods: This nationwide population-based observation of all consecutively enrolled Japanese adult OHCA patients with resuscitation attempts from 2005 to 2012. The primary outcome was 1-month survival with a neurologically favorable outcome. Calendar days at three national meetings (Japanese Society of Intensive Care Medicine, Japanese Association for Acute Medicine, and Japanese Circulation Society) were obtained for each year during the study period, because medical professionals who belong to these academic societies play an important role in treating OHCA patients after hospital admission, and we identified two groups: the exposure group included OHCAs that occurred on meeting days, and the control group included OHCAs that occurred on the same days of the week 1 week before and after meetings. Multiple logistic regression analysis was used to adjust for confounding variables.Results: A total of 20 143 OHCAs that occurred during meeting days and 38 860 OHCAs that occurred during non-meeting days were eligible for our analyses. The proportion of patients with favorable neurologic outcomes after whole arrests did not differ during meeting and non-meeting days (1.6% [324/20 143] vs 1.5% [596/38 855]; adjusted odds ratio 1.02; 95% confidence interval, 0.88–1.19). Regarding bystander-witnessed ventricular fibrillation arrests of cardiac origin, the proportion of patients with favorable neurologic outcomes also did not differ between the groups.Conclusions: In this population, there were no significant differences in outcomes after OHCAs that occurred during national meetings of professional organizations related to OHCA care and those that occurred during non-meeting days.
