Introduction: Multiple citizen responder (CR) programs worldwide which dispatch laypersons to out-of-hospital cardiac arrest (OHCA) to perform cardiopulmonary resuscitation (CPR) and use of automated external defibrillators (AEDs) were affected by the COVID-19 outbreak in 2020, but little is known about how the pandemic affected CR activation and initiation of bystander CPR and defibrillation. In Denmark, the CR program continued to run during lockdown but with the recommendation to perform chest-compression-only CPR in contrast to standard CPR including ventilations. We hypothesized that bystander interventions as CPR and AED usage decreased during the first COVID-19 lockdown in two regions of Denmark in the spring of 2020. Methods: All OHCAs from January 1, 2020 to June 30, 2020 with CR activation from the Danish Cardiac Arrest Registry and the National Citizen Responder database. Bystander CPR, AED usage, and CRs’ alarm acceptance rate during the national lockdown from March 11, 2020 to April 20, 2020 were compared with the non-lockdown period from January 1, 2020 to March 10, 2020 and from April 21 to June 30, 2020. Results: A total of 6,120 CRs were alerted in 443 (23/100.000 inhabitants) cases of presumed OHCA of which 256 (58%) were confirmed cardiac arrests. Bystander CPR remained equally high in the lockdown period compared with non-lockdown period (99% vs. 92%, p=0.07). Likewise, there was no change in bystander defibrillation (9% vs. 14%, p=0.4). There was a slight increase in the number of CRs who accepted an alarm (7 per alarm, IQR 4) during lockdown compared with non-lockdown period (6 per alarm, IQR 4), p=0.0001. The proportion of patients achieving return of spontaneous circulation at hospital arrival was also unchanged (lockdown 23% vs non-lockdown 23%, p=1.0) (Table 1). Conclusion: Bystander initiated resuscitation rates did not change during the first COVID-19 lockdown in Denmark for OHCAs where CRs were activated through a smartphone app.

Objective: In cardiac arrest cases, high quality cardiopulmonary resuscitation and effective chest compression are vital issues in improving survival with good neurological outcomes. In this study, we investigated the effect of mechanical chest compression devices on 30- day survival in out-of-hospital cardiac arrest. Materials and Methods: This retrospective case-control study was performed on patients who were over 18 years of age and admitted to the emergency department for cardiac arrest between January 1, 2016 and January 15, 2018. Manual chest compression was performed to the patients before January 15, 2017, and mechanical chest compression was performed after this date. Return of spontaneous circulation, hospital discharge, and 30-day survival rates were compared between the groups of patients in terms of chest compression type. In this study, the LUCAS-2 model piston-based mechanical chest compression device was used for mechanical chest compressions. Results: The rate of return of spontaneous circulation was significantly lower in the mechanical chest compression group (11.1% vs 33.1%; p < 0.001). The 30-day survival rate was higher in the manual chest compression group (6.8% vs 3.7%); however, this difference was not statistically significant (p = 0.542). Furthermore, 30-day survival was 0% in the trauma group and 0.6% in the patient group who underwent cardiopulmonary resuscitation for over 20 minutes. Conclusion: It can be seen that the effect of mechanical chest compression on survival is controversial; studies on this issue should continue and, furthermore, studies on the contribution of mechanical chest compression on labor loss should be conducted.

Introduction: Evidence for the effectiveness of coronary angiography after out-of-hospital cardiac arrest (OHCA) is conflicting. Our objective was to evaluate the association between receiving coronary angiography within 72 hours of hospital arrival and survival with favorable neurologic outcome. Methods: This was a population-based retrospective cohort study of consecutive cases of adult OHCA transported to and treated at 28 hospitals in Southern Ontario between March 1, 2010 and December 31, 2014. We included patients with atraumatic OHCA, who achieved return of spontaneous circulation, and were alive 6 hours after hospital arrival. Multi-level logistic regression was used to measure the association between early coronary angiography and neurologically intact survival (Modified Rankin Score 0-2), while controlling for potential confounders and clustered data. We controlled for age, sex, initial cardiac rhythm, witness status, bystander resuscitation, EMS response time, prehospital return of spontaneous circulation, location of arrest, daytime presentation, neurologic status at hospital arrival, STEMI status, cardiac history, initiation of therapeutic hypothermia, hospital size and type, and hospital annual cardiac arrest volume. Results: During the period of study, 2678 consecutive OHCA patients met the inclusion criteria. The mean age was 66(±16), 31.7% were female, 54.1% had a bystander witnessed arrest, 35.2% received bystander CPR, 45.9% had a shockable initial rhythm, 30.1% had ST elevation on the first post arrest ECG, and 32.4% received coronary angiography. Receiving coronary angiography was strongly associated with neurologically intact survival (OR 2.30, CI95 1.69-3.15) and survival (OR 2.08, CI95 1.53-2.82). A similar association was observed in the subgroup of patients without STEMI (OR 3.24, CI95 2.16-4.87 and OR 2.66, CI95 1.78-3.99, respectively). Conclusions: Neurologically intact survival among post cardiac arrest patients may be improved with coronary angiography, particularly for patients without STEMI. This observation should be confirmed with future randomized controlled studies.

Background Despite a continued focus on improved cardiopulmonary resuscitation quality, survival remains low from in-hospital cardiac arrest. Advanced Resuscitation Training has been shown to improve survival to hospital discharge and survival with good neurological outcome following in-hospital cardiac arrest at its home institution. We sought to determine if Advanced Resuscitation Training implementation would improve patient outcomes and cardiopulmonary resuscitation quality at our institution. Methods This was a prospective, before–after study of adult in-hospital cardiac arrest victims who had cardiopulmonary resuscitation performed. During phase 1, standard institution cardiopulmonary resuscitation training was provided. During phase 2, providers received the same quantity of training, but with emphasis on Advanced Resuscitation Training principles. Primary outcomes were return of spontaneous circulation, survival to hospital discharge, and neurologically favorable survival. Secondary outcomes were cardiopulmonary resuscitation quality parameters. Results A total of 156 adult in-hospital cardiac arrests occurred during the study period. Rates of return of spontaneous circulation improved from 58.1 to 86.3% with an adjusted odds ratios of 5.31 (95% CI: 2.23–14.35, P < 0.001). Survival to discharge increased from 26.7 to 41.2%, adjusted odds ratios 2.17 (95% CI: 1.02–4.67, P < 0.05). Survival with a good neurological outcome increased from 24.8 to 35.3%, but was not statistically significant. Target chest compression rate increased from 30.4% of patients in P1 to 65.6% in P2, adjusted odds ratios 4.27 (95% CI: 1.72–11.12, P = 0.002), and target depth increased from 23.2% in P1 to 46.9% in P2, adjusted odds ratios 2.92 (95% CI: 1.16–7.54, P = 0.024). Conclusions After Advanced Resuscitation Training implementation, there were significant improvements in cardiopulmonary resuscitation quality and rates of return of spontaneous circulation and survival to discharge.

Abstract Background The COVID-19 outbreak requires a permanent adaptation of practices. Cardiopulmonary resuscitation (CPR) is also involved and we evaluated these changes in the management of out-of-hospital cardiac arrest (OHCA). Methods OHCA of medical origins identified from the French National Cardiac Arrest Registry between March 1st and April 31st 2020 (COVID-19 period), were analysed. Different resuscitation characteristics were compared with the same period from the previous year (non-COVID-19 period). Results Overall, 1005 OHCA during the COVID-19 period and 1620 during the non-COVID-19 period were compared. During the COVID-19 period, bystanders and first aid providers initiated CPR less frequently (49.8% versus 54.9%; difference, − 5.1 percentage points [95% CI, − 9.1 to − 1.2]; and 84.3% vs. 88.7%; difference, − 4.4 percentage points [95% CI, − 7.1 to − 1.6]; respectively) as did mobile medical teams (67.3% vs. 75.0%; difference, − 7.7 percentage points [95% CI, − 11.3 to − 4.1]). First aid providers used defibrillators less often (66.0% vs. 74.1%; difference, − 8.2 percentage points [95% CI, − 11.8 to − 4.6]). Return of spontaneous circulation (ROSC) and D30 survival were lower during the COVID-19 period (19.5% vs. 25.3%; difference, − 5.8 percentage points [95% CI, − 9.0 to − 2.5]; and 2.8% vs. 6.4%; difference, − 3.6 percentage points [95% CI, − 5.2 to − 1.9]; respectively). Conclusions During the COVID-19 period, we observed a decrease in CPR initiation regardless of whether patients were suspected of SARS-CoV-2 infection or not. In the current atmosphere, it is important to communicate good resuscitation practices to avoid drastic and lasting reductions in survival rates after an OHCA.

Abstract A retrospective patient record analysis of the Emergency Medial Service’s Rîga City Regional Centre was provided from January 2012 through December 2013. 1359 adult patients were CPR treated for out-of-hospital cardiac arrest according to ERC Guidelines 2010. A total of 490 patients were excluded from the study. The main outcome measure was survival to hospital admission. Of 869 CPR-treated patients, 60% (n = 521) were men. The mean age of patients was 66.68 ± 15.28 years. The survival rate to hospital admission was 12.9% (n = 112). 54 of survived patients were women. Mean patient age of successful CPR was 63.22 ± 16.21 and unsuccessful CPR 67.20 ± 15.09. At least one related illness was recorded with 63.4% (n = 551) patients. There were 61 survivors in bystander witnessed OHCA and nine survivors in unwitnessed OHCA. The rate of bystander CPR when CA (cardiac arrest) was witnessed was 24.8%. Ventricular fibrillation (VF) as initial heart rhythm was significantly associated with survival to hospital admission in 54 cases (p < 0.0001). Age and gender affected return of spontaneous circulation. Survival to hospital admission had rhythm-specific outcome. Presence of OHCA witnesses improved outcome compared to bystander CPR. The objective of this study was to report patient characteristics, the role of witnesses in out-of-hospital cardiac arrest (OHCA) and outcome of adult cardiopulmonary resuscitation

Purpose: Survival rates after non-shockable out-of-hospital cardiac arrest (OHCA) remain low despite advances in resuscitation. Cardiopulmonary resuscitation (CPR) process measures may inform treatment strategies. We hypothesized that CPR process measures would be associated with return of spontaneous circulation (ROSC) and patient electrocardiogram (ECG) transitions. Methods: We obtained defibrillator monitor data for emergency medical service (EMS)-treated non-shockable OHCA from the Resuscitation Outcomes Consortium (ROC), an OHCA research network (U.S./Canada). We extracted ECG data from EMS defibrillator files and parsed cases into compression-free analyzable segments using custom MATLAB software. Two data abstractors classified segment rhythms as PEA, asystole, ventricular fibrillation (VF), pulseless ventricular tachycardia (PVT), or ROSC. We calculated CPR process measures (average rate, depth, duration, leaning proportion, chest compression fraction, and duty cycle) for CPR bouts preceding every ECG segment. We used mixed effects models controlling for subject to test associations between individual CPR process measures and the bout-level outcomes ROSC and shockable rhythm. Results: We analyzed 1893 cases consisting of 7981 CPR bouts. Case initial rhythms were asystole (68.2%), PEA (24.9%), or NSA-AED (6.9%). Segment rhythm classifications were asystole (78.1%), PEA (20.4%), ROSC (5.5%), VF (1.4%), and PVT (0.07%). Regression model results are shown in Table 1. Chest compression fraction was most strongly associated with ROSC and shockable rhythm. Depth was also associated with shockable rhythm. Leaning proportion and duty cycle were not associated with either outcome. Conclusions: In cases of non-shockable OHCA, CPR quality measures were associated with ROSC and transition to a shockable rhythm at the bout level.

Background: The reporting and analysing of data of out-of-hospital cardiac arrests encourages the quality improvement of the emergency medical services. For this reason, the establishment of a sufficiently large patient database is intended to allow analysis of resuscitation treatments for out-of-hospital cardiac arrests and performances of different emergency medical services. Aims: The aim of this study was to describe the demographics, characteristics, outcomes and determinant factors of survival for patients who suffered an out-of-hospital cardiac arrest. Methods: this was a retrospective study including all out-of-hospital cardiac arrest cases treated by the emergency medical service in the district of Udine (Italy) from 1 January 2010–31 December 2014. Results: A total of 1105 out-of-hospital cardiac arrest patients were attended by the emergency medical service. Of these, 489 (44.2%) underwent cardiopulmonary resuscitation, and return of spontaneous circulation was achieved in 142 patients (29%). There was a male predominance overall, and the main age was 72.6 years (standard deviation 17.9). Cardiopulmonary resuscitation before emergency medical service arrival was performed on 62 cases (44%) in the return of spontaneous circulation group, and on 115 cases (33%) in the no return of spontaneous circulation group ( p<0.024). Among the 142 cases of return of spontaneous circulation, 29 (5.9%) survived to hospital discharge. There was a smaller likelihood of return of spontaneous circulation when patients were female (odds ratio 0.61, 0.40–0.93). Patients who had an out-of-hospital cardiac arrest with an initial shockable rhythm (odds ratio 6.33, 3.86–10.39) or an age <60 years (odds ratio 2.91, 1.86–4.57) had a greater likelihood of return of spontaneous circulation. In addition, bystander cardiopulmonary resuscitation (odds ratio 1.56, 1.04–2.33) was associated with an increased chance of return of spontaneous circulation. Conclusion: The incidence of out-of-hospital cardiac arrest and survival rate lies within the known range. A wider database is necessary to achieve a better knowledge of out-of-hospital cardiac arrest and to drive future investments in the healthcare system.

Background: In-hospital cardiac arrest is a major cause of death in European countries, and survival of patients remains low ranging from 20% to 25%. Aims: The purpose of this study was to assess healthcare professionals’ knowledge on cardiopulmonary resuscitation among university hospitals in 12 European countries and correlate it with the return of spontaneous circulation rates of their patients after in-hospital cardiac arrest. Methods and results: A total of 570 healthcare professionals from cardiology, anaesthesiology and intensive care medicine departments of European university hospitals in Italy, Poland, Hungary, Belgium, Spain, Slovakia, Germany, Finland, The Netherlands, Switzerland, France and Greece completed a questionnaire. The questionnaire consisted of 12 questions based on epidemiology data and cardiopulmonary resuscitation training and 26 multiple choice questions on cardiopulmonary resuscitation knowledge. Hospitals in Switzerland scored highest on basic life support ( P=0.005) while Belgium hospitals scored highest on advanced life support ( P<0.001) and total score in cardiopulmonary resuscitation knowledge ( P=0.01). The Swiss hospitals scored highest in cardiopulmonary resuscitation training ( P<0.001). Correlation between cardiopulmonary resuscitation knowledge and return of spontaneous circulation rates of patients with in-hospital cardiac arrest demonstrated that each additional correct answer on the advanced life support score results in a further increase in return of spontaneous circulation rates (odds ratio 3.94; 95% confidence interval 2.78 to 5.57; P<0.001). Conclusion: Differences in knowledge about resuscitation and course attendance were found between university hospitals in 12 European countries. Education in cardiopulmonary resuscitation is considered to be vital for patients’ return of spontaneous circulation rates after in-hospital cardiac arrest. A higher level of knowledge in advanced life support results in higher return of spontaneous circulation rates.
