Introduction: In Denmark, survival after out-of-hospital cardiac arrest (OHCA) has increased markedly in the past years, from 3.9% in 2001 to 15.8% in 2019. Still, bystander defibrillation remains low, especially for OHCAs in residential areas. To improve bystander defibrillation, smartphone activated Citizen Responder (CR) Programs have expanded to nationwide coverage in Denmark during September 2017 to May 2020. Hypothesis: Implementation of CR programs in Denmark was associated with increased bystander CPR and defibrillation. Methods: We conducted an observational study of 15,308 OHCAs from the Danish Cardiac Arrest Registry from 2016-2019. App-based CR programs were implemented in four out of five Danish regions during the study period. All OHCAs were divided into two groups according to the date of CR implementation (“before” and “after CR” implementation). The groups were compared focusing on bystander defibrillation, bystander CPR and 30-day survival. Results: “Before CR” included 8,819 OHCAs and the “after CR” 6,489 OHCAs. The proportion of bystander CPR was 77.9% and 78.0% (p-value 0.91) for the before -and after CR implementation groups, respectively. The corresponding numbers for bystander defibrillation were 7.4% and 9.5% (p-value < 0.001), respectively. In residential OHCA, bystander defibrillation went from 4.0% to 6.3% (p-value<0.001) in the before -and after group respectively. In public, bystander defibrillation was 19.3% and 22.2% (p-value 0.05) in the groups respectively. 30-day survival was 12.7% before and 13.1% after CR implementation (p-value 0.49). Conclusion: We found no changes in bystander CPR or 30-day survival following implementation of CR programs in Denmark, but a significant increase in bystander defibrillation for all OHCAs. Importantly bystander defibrillation also increased significantly in residential locations, where the majority of OHCAs occur and where bystander defibrillation has remained low for decades.

Introduction: Out-of-hospital cardiac arrest (OOHCA) victims are increasing, but emergency medical service system (EMSS) is not ready for them in Korea. A previous randomized, controlled clinical trial has suggested that vasopressin followed epinephrine was superior to epinephrine in patients with asystole. According to the Korean national registry of OOHCA, patients with asystole were more than two thirds of them. In Korean EMSS, no drugs are permitted to administer in the prehospital phase by law. Thereafter epinephrine or vasopressin cannot be administered until patients are transported to emergency departments (EDs). This study was to evaluate whether the combined administration of vasopressin and epinephrine in ED for OOHCA patients would increase the return of spontaneous circulation (ROSC) and survival discharge. Methods: From October 2007 to May 2008, we changed the CPR protocol in adult, nontraumatic OOHCA that 40 U of vasopressin was administered as soon as possible after the first dose of epinephrine (the after group). Cardiac arrest data were collected using the Utstein template. Data from January to September 2007, when vasopressin has not been used, were also collected for comparative analysis (the before group). These two groups were compared in terms of ROSC, and survival discharge Results: There were 45 and 50 patients in the before and after groups, respectively. There was no significant differences in the initial ECG rhythm of asystole (67% vs 78%), witnessed arrest (73% vs 72%), bystander CPR (16% vs 10%), time from collapse to BLS time (6 min vs 8.5 min), and time from collapse to study drugs (23 min vs 26.5 min). The rate of sustained ROSC was similar between the before and after groups (53% vs 48%, P=0.604) as was the survival discharge (27% vs 14%, P=0.123). Conclusions: Vasopressin with administerd with epinephrine does not increase the rate of ROSC nor the survival discharge.

AbstractEarly defibrillation improves survival for patients suffering cardiac arrest from ventricular fibrillation (VF) or ventricular tachycardia (VT). Automated external defibrillators (AEDs) should be placed in locations in which there is a high incidence of out-of-hospital cardiac arrest (OOHCA). The study objective was to identify high-risk, rural locations that might benefit from AED placement. A retrospective review of OOHCA in a rural community during the past 5.5 years was conducted. The OOHCAs that occurred in non-residential areas were categorized based on location. Nine hundred, forty OOHCAs occurred during the study period of which 265 (28.2%) happened in non-residential areas. Of these, 127 (47.9%) occurred in healthcare-related locations, including 104 (39.2%) in extended care facilities. No location used in this study had more than two OOHCAs. Most (52.1%) non-residential OOHCAs occurred as isolated events in 146 different locations. Almost half of the OOHCAs that occurred in non-residential areas took place in healthcare-related facilities suggesting that patients at these locations may benefit from AED placement. First responders with AEDs are likely to have the greatest impact in a rural community.

AimsA short awareness time interval (ATI, time from witnessing the arrest to calling for help) and bystander cardiopulmonary resuscitation (CPR) are important factors affecting neurological recovery after out-of-hospital cardiac arrest (OHCA). This study investigated the association of the location of OHCA with the length of ATI and bystander CPR.MethodsThis population-based observational study used the nationwide Korea OHCA database and included all adults with layperson-witnessed OHCA with presumed cardiac aetiology between 2013 and 2017. The exposure was the location of OHCA (public places, private housing and nursing facilities). The primary outcome was short ATI, defined as <4 min from witnessing to calling for emergency medical service (EMS). The secondary outcome was the frequency of provision of bystander CPR. Multivariable logistic regression analysis was performed to evaluate the association of location of OHCA with study outcomes.ResultsOf 30 373 eligible OHCAs, 66.6% occurred in private housing, 24.0% occurred in public places and 9.4% occurred in nursing facilities. In 67.3% of the cases, EMS was activated within 4 min of collapse, most frequently in public places (public places 77.0%, private housing 64.2% and nursing facilities 64.8%; p<0.01). The overall rate of bystander CPR was 65.5% with highest in nursing facilities (77.0%), followed by public places (70.1%) and private housing 62.3%; p<0.01). Compared with public places, the adjusted ORs (AORs) (95% CIs) for a short ATI were 0.58 (0.54 to 0.62) in private housing and 0.62 (0.56 to 0.69) in nursing facilities. The AORs (95% CIs) for bystander CPR were 0.75 (0.71 to 0.80) in private housing and 1.57 (1.41 to 1.75) in nursing facilities.ConclusionOHCAs in private housing and nursing facilities were less likely to have immediate EMS activation after collapse than in public places. A public education is needed to increase the awareness of necessity of prompt EMS activation.

Abstract Background Sudden cardiac death remains a leading cause of mortality in Canada, resulting in more than 35,000 deaths annually. Most cardiac arrest victims collapse in their own home (85% of the time) and 50% are witnessed by a family member or bystander. Survivors have a quality of life similar to the general population, but the overall survival rate for out-of-hospital cardiac arrest (OHCA) rarely exceeds 8%. Victims are almost four times more likely to survive when receiving bystander CPR, but bystander CPR rates have remained low in Canada over the past decade, not exceeding 15–25% until recently. Telecommunication-assisted CPR instructions have been shown to significantly increase bystander CPR rates, but agonal breathing may be misinterpreted as a sign of life by 9–1-1 callers and telecommunicators, and is responsible for as much as 50% of missed OHCA diagnoses. We sought to improve the ability and speed with which ambulance telecommunicators can recognize OHCA over the phone, initiate timely CPR instructions, and improve survival. Methods In this multi-center national study, we will implement and evaluate an educational program developed for ambulance telecommunicators using a multiple baseline interrupted time-series design. We will compare outcomes 12 months before and after the implementation of a 20-min theory-based educational video addressing barriers to recognition of OHCA while in the presence of agonal breathing. Participating Canadian sites demonstrated prior ability to collect standardized data on OHCA. Data will be collected from eligible 9–1-1 recordings, paramedic documentation and hospital medical records. Eligible cases will include suspected or confirmed OHCA of presumed cardiac origin in patients of any age with attempted resuscitation. Discussion The ability of telecommunication-assisted CPR instructions to improve bystander CPR and survival rates for OHCA victims is undeniable. The ability of telecommunicators to recognize OHCA over the phone is unequivocally impeded by relative lack of training on agonal breathing, and reluctance to initiate CPR instructions when in doubt. Our pilot data suggests the potential impact of this project will be to increase absolute OHCA recognition and bystander CPR rates by at least 10%, and absolute out-of-hospital cardiac arrest survival by 5% or more.

Abstract Background Out-of-hospital cardiac arrest (OHCA), a global health problem with a survival rate ranging from 2 to 22% across different countries, has been a leading cause of premature death for decades. The aim of this study was to evaluate the trends of survival after OHCA over time and its relationship with bystander cardiopulmonary resuscitation (CPR), initial shockable rhythm, return of spontaneous circulation (ROSC), and survived event. Methods In this prospective observational study, data of OHCA patients were collected following the “Utstein style” by the Beijing, China, Emergency Medical Service (EMS) from January 2011 (data from February to June in 2011 was not collected) to October 2016. Patients who had a cardiac arrest and for whom an ambulance was dispatched were included in this study. All cases were followed up to determine hospital discharge or death. The trend of OHCA survival was analyzed using the Chi-square test. The relationship among bystander CPR, initial shockable rhythm, ROSC, survived event, and OHCA survival rate was analyzed using multivariate path analyses with maximum standard likelihood estimation. Results A total of 25,421 cases were transferred by the Beijing EMS; among them, 5042 (19.8%) were OHCA (median age: 78 years, interquartile range: 63–85, 60.1% male), and 484 (9.6%) received bystander CPR. The survival rate was 0.6%, which did not improve from 2012 to 2015 (P = 0.569). Overall, bystander CPR was indirectly associated with an 8.0% (β = 0.080, 95% confidence interval [CI] = 0.064–0.095, P = 0.002) increase in survival rate. The indirect effect of bystander CPR on survival rate through survived event was 6.6% (β = 0.066, 95% CI = 0.051–0.081, P = 0.002), which accounted for 82.5% (0.066 of 0.080) of the total indirect effect. With every 1 increase in survived event, the possibility of survival rate will directly increase by 53.5% (β = 0.535, 95% CI = 0.512–0.554, P = 0.003). Conclusions The survival rate after OHCA was low in Beijing which has not improved between 2012 and 2015. The effect of bystander CPR on survival rate was mainly mediated by survived event.

Abstract Background Knowledge about the effect of bystander cardiopulmonary resuscitation (CPR) in out-of-hospital cardiac arrest (OHCA) of non-cardiac origin is lacking. We aimed to investigate the association between bystander CPR and survival in OHCA of presumed non-cardiac origin. Methods From the Danish Cardiac Arrest Registry and through linkage with national Danish healthcare registries we identified all adult patients with OHCA of presumed non-cardiac origin in Denmark (2001–2014). These were categorized further into OHCA of medical and non-medical cause. We analyzed temporal trends in bystander CPR and 30-day survival during the study period. Multiple logistic regression was used to examine the association between bystander CPR and 30-day survival and reported as standardized 30-day survival chances with versus without bystander CPR standardized to the prehospital OHCA-factors and patient characteristics of all patients in the study population. Results We identified 10,761 OHCAs of presumed non-cardiac origin. Bystander CPR was associated with an increased 30-day survival chance of 3.4% (95% confidence interval [CI]: 2.9–3.9) versus 1.8% (95% CI: 1.4–2.2) with no bystander CPR, corresponding to a significant difference of 1.6% (95% CI: 0.9–2.3). During the study period, the overall bystander CPR rates increased from 13.6% (95% CI: 11.2–16.5) to 62.7% (95% CI: 60.2–65.2). 30-day survival increased overall from 1.3% (95% CI: 0.7–2.6) to 4.0% (95% CI: 3.1–5.2). Similar findings were observed in subgroups of medical and non-medical OHCA. Table 1. Patient and arrest characteristics according to cause of out-of-hospital cardiac arrest Overall Medical OHCA Non-medical OHCA Patient characteristics   Total patients 10761 7625 3136   Median age,y 67 70 50   Male, n (%) 6357 (59.1) 4154 (54.5) 2204 (70.4) OHCA factors   Witnessed arrest, n (%) 4306 (40.0) 3574 (46.9) 732 (23.3)   Public location, n (%) 6979 (64.9) 5494 (72.1) 1485 (47.4) OHCA, out-of-hospital cardiac arrest; CPR, cardiopulmonary resuscitation. Figure 1. Temporal trends Conclusion Bystander CPR was associated with a higher chance of 30-day survival among OHCA of presumed non-cardiac origin regardless of the underlying cause (medical/non-medical). Rates of bystander CPR and 30-day survival improved during the study period.
