Introduction: Although studies have shown that bystander cardiopulmonary resuscitation (CPR) in witnessed out-of-hospital cardiac arrest (OHCA) is associated with better neurological prognosis, whether bystander and Emergency Medical Service (EMS) interventions are associated with prognosis in unwitnessed OHCA patients is not fully elucidated. We aimed to investigate the prognostic importance of bystander and EMS interventions among unwitnessed OHCA patients in Japan. Methods and Results: This study was a nation-wide population-based observational study of OHCA in Japan from 2011 to 2015 based on data from the All-Japan Utstein Registry. The outcome measures were neurological outcome and survival at 30-day. The neurologically favorable outcome was defined as Glasgow-Pittsburgh cerebral performance category score 1 or 2. First, to investigate the effectiveness of bystander interventions, we included 105,655 unwitnessed cardiogenic OHCA patients (aged 18-80 years). Of these, 1,614 (1.5%) showed neurologically favorable outcome and 3,273 (3.1%) survived at 30-day. Multivariate logistic regression analysis adjusting for age, sex, geographical region, year and EMS response time showed that bystander CPR was associated with neurologically favorable outcome (adjusted odds ratio [aOR] 1.49, 95% CI 1.35-1.65, P<0.001). Additionally, to investigate the effectiveness of EMS interventions for patients with non-shockable rhythm, we examined 43,342 patients who were performed public CPR and had the initial rhythm of pulseless electrical activity (PEA) or asystole. Of these, 101 (0.2%) showed neurologically favorable outcome and 453 (1.0%) were survival at 30-day. Advanced airway management by EMS was negatively associated with neurologically favorable outcome (aOR 0.55, 95% CI 0.37-0.81, P=0.003) and administration of epinephrine by EMS was associated with survival (aOR 2.35, 95% CI 1.89-2.92, P<0.001). Conclusions: Among unwitnessed OHCA patients, bystander CPR was associated with neurologically favorable prognosis. For unwitnessed OHCA patients with non-shockable rhythm, epinephrine administration was associated with survival, but advanced airway management was negatively associated with neurological outcome.

ObjectivesTo investigate the association of prehospital advanced airway management (AAM) on outcomes of emergency medical service (EMS)-witnessed out-of-hospital cardiac arrest (OHCA) according to the location of arrest.MethodsWe evaluated a Korean national OHCA database from 2012 to 2016. Adults with EMS-witnessed, non-traumatic OHCA were included. Patients were categorised into four groups according to whether prehospital AAM was conducted (yes/no) and location of arrest (‘at scene’ or ‘in the ambulance’). The primary outcome was discharge with good neurological recovery (cerebral performance category 1 or 2). Multivariable logistic regression analysis was conducted to evaluate the association between AAM and outcome according to the location of arrest.ResultsAmong 6620 cases, 1425 (21.5%) cases of arrest occurred ‘at the scene’, and 5195 (78.5%) cases of arrest occurred ‘in an ambulance’. Prehospital AAM was performed in 272 (19.1%) OHCAs occurring ‘at the scene’ and 645 (12.4%) OHCAs occurring ‘in an ambulance’. Patients with OHCA in the ambulance who had prehospital AAM showed the lowest good neurological recovery rate (6.0%) compared with OHCAs in the ambulance with no AAM (8.9%), OHCA at scene with AAM (10.7%) and OHCA at scene with no AAM (7.7%). For OHCAs occurring in the ambulance, the use of AAM had an adjusted OR of 0.67 (95% CI 0.45 to 0.98) for good neurological recovery.ConclusionOur data show no benefit of AAM in patients with EMS-witnessed OHCA. For patients with OHCA occurring in the ambulance, AAM was associated with worse clinical outcome.

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: Effective advanced life support is one of the important link in the chain of survival. In Japan, the emergency medical service (EMS) personnel can perform defibrillation, advanced airway management, intravenous access and administration of epinephrine as an advanced life support intervention for the treatment of out-of-hospital cardiac arrest (OHCA). However, whether these interventions performed by EMS improves neurological outcomes remains unclear. Objective: To evaluate predictors of favorable neurological outcome in patients suffering OHCA with ventricular fibrillation (VF) witnessed by an EMS personnel. Methods: The Fire and Disaster Management Agency (FDMA) of Japan developed a nationwide database of a prospective population-based cohort using an Utstein-style template for OHCA patients since January 2005. To evaluate data after the publication of Guideline2010, data from January 2011 to December 2015 of this database was used for the current analysis. A multivariate logistic-regression analysis was performed to assess factors associated with favorable neurological outcome (defined as Cerebral Performance Category 1 or 2) 1 month after cardiac arrest. Results: Of the 629,471 patients documented for the study period, 2,301 adult patients with an OHCA of cardiac origin and VF for the initial rhythm witnessed by an EMS personnel were included in the present analysis. The overall mortality was 49.6%. Rate of return of spontaneous circulation and favorable neurological outcome were 53.4% and 44.8%, respectively. High age (OR0.387, 95%CI0.316-0.472, p<0.001), delayed defibrillation (OR0.598, 95%CI0.493-0.723, p<0.001), advanced airway management (OR0.305, 95%CI0.223-0.413, p<0.001), administration of epinephrine (OR0.356, 95%CI0.213-0.585, p<0.001) and multiple attempts of defibrillation (OR0.484, 95%CI0.402-0.582, p<0.001) were negatively associated with favorable neurological outcome. Conclusion: In patients with VF witnessed by EMS personnel, resuscitation efforts should simply focus on early defibrillation and CPR without advanced interventions.

Low Exposure

Objectives: The exposure of emergency medical service personnel (paramedics) to out-of-hospital cardiac arrest (OHCA) and resuscitation procedures could be an important factor in skill maintenance and quality of care. This study aims to describe paramedic exposure to OHCA resuscitation in the state of Victoria, Australia (population 5.8 million). Methods: We extracted and linked data from the Victorian Ambulance Cardiac Arrest Registry (VACAR) and Ambulance Victoria’s employment dataset for the period 2003-2012. Paramedics were considered to have ‘exposure’ to OHCA if they attended a case where resuscitation was attempted. Individual rates were calculated for annual exposure (number of OHCA exposures for each paramedic/years employed in study period) and days between exposures (total paramedic days/total number of exposures). Results: Over the 10-year period, there were 49,107 OHCAs and 5,673 paramedics employed. Resuscitation was attempted in 44% of patients. An average of 3.2 (SD±1.1) paramedics attended each case. The median average exposure of paramedics was 2.2 (IQR=1.2-3.5) OHCAs/year. The proportion with no exposures in a year increased from 39% in 2003 to 43% in 2012 ( p =0.036). OHCA exposure was significantly less in those employed part-time or casual ( p <0.001), in a rural area ( p <0.001) or with a lower qualification ( p <0.001) (Table). Annual exposure to pediatric and traumatic OHCAs was particularly low (Table). Paramedics were exposed to an average of 0.006 OHCAs/day, meaning it would take an average of 163 days be exposed to OHCA and up to 12.5 years for rare cases, such as pediatric OHCAs. Conclusion: Our study identified paramedic exposure to resuscitation is low and has decreased over time. This highlights the importance of supplementing paramedic exposure with other methods, such as simulation, to maintain resuscitation skills. This may be particularly important to paramedics with low exposure and for rare case types, such as pediatric OHCA.

Introduction: In Japan, emergency medical service (EMS) providers are prohibited from cardiopulmonary resuscitation (CPR) termination in the field and must transport all out-of-hospital cardiac arrest (OHCA) patients to a hospital, regardless of the return of spontaneous circulation (ROSC). We previously developed a termination of resuscitation (TOR) rule for emergency department physicians (ED-TOR) treating OHCA patients using data from the All-Japan Utstein Registry between 2005 and 2009, when CPR was performed according to the 2005 guidelines. The ED-TOR rule recommends CPR termination when patients in the emergency department meet all of the following criteria: initial unshockable rhythm, arrest unwitnessed by bystanders and no prehospital ROSC. Hypothesis: We aimed to validate the ED-TOR rule using more recent data, where CPR was performed according to the 2010 and 2015 guidelines, comparing the relevance of the ED-TOR rule with the universal basic life support TOR (BLS-TOR) rule, which consists of the following criteria: no prehospital ROSC, unwitnessed arrest by EMS providers and no shock received. Methods: We analysed 552,554 OHCA patients (age ≥ 18 years) treated by EMS providers. OHCA patients witnessed by EMS providers were excluded. Data were obtained from a prospectively recorded All-Japan Utstein Registry from 2013 to 2017. The study endpoints were specificity and a positive predictive value (PPV) for predicting 1-month mortality after OHCA with the ED-TOR and BLS-TOR rules. Results: The overall 1-month survival rate was 4.3% (23,733/552,554). The proportions of OHCA patients who fulfilled the ED-TOR and BLS-TOR criteria were 59.6% and 83.8%, respectively. The specificity and PPV of the ED-TOR and BLS-TOR rules for predicting 1-month mortality were 93.2% (95% confidence interval [CI], 92.8%-93.5%) and 99.5% (95% CI, 99.5%-99.5%) and 82.6% (95% CI, 82.1%-83.1%) and 99.1% (95% CI, 99.1%-99.1%), respectively. Conclusions: The ED-TOR rule was successfully validated using more recent data from a Japanese registry where CPR was performed according to the 2010 and 2015 guidelines. The ED-TOR rule was slightly superior to the BLS-TOR rule in Japanese EMS systems showing high specificity and PPV for predicting 1-month mortality.
