Introduction: In out-of-hospital cardiac arrest (OHCA) patients during shockable rhythm, the epinephrine administration after second defibrillation is recommended by the 2015 ILCOR/CoSTR guidelines. However, there is insufficient evidence regarding the proper timing of epinephrine administration particularly in relation to defibrillation. Hypothesis: The timing of epinephrine after first defibrillation (D-E interval) was associated with clinical outcome in OHCA patients. Methods: Between 2011 and 2016, we enrolled 753,025 OHCA patients from nationwide prospective population-based registry in Japan. Following exclusion criteria, a total of 1,559 patients with witnessed by bystanders and shockable rhythm on the initial electrocardiogram who administrated epinephrine after defibrillation by emergency medical service personnel and obtained return of spontaneous circulation in prehospital setting were eligible for the study. We evaluated the association between D-E interval and favorable neurological outcome (cerebral performance category: 1 or 2) at 30 days. To evaluate predictor for better neurological outcome, study patients were categorized as every 2 minutes up to 20 minutes, and more than 20 minutes. Results: Patients with favorable neurological outcome were 22% (N=348). Patients with favorable neurological outcome had a shorter D-E interval than those with non-favorable neurological outcome (7.9±4.1vs 10.2±5.3 min, p<0.001). Multivariate logistic regression analysis showed that D-E interval at more than 10 minutes, when D-E interval at 2 to 3 minutes as defined reference, was a significant predictor for non-favorable neurological outcome ( Table ). Conclusion: Delayed epinephrine administration after first defibrillation (D-E interval >10 minutes) was significantly associated with non-favorable neurological outcome.

Background: The 2010 guidelines have stressed that systematic post-cardiac arrest care after return of spontaneous circulation (ROSC) can improve the likelihood of patient survival with good neurological outcome. However, the 2010 guidelines showed that induced therapeutic hypothermia may be considered for comatose adult patients with ROSC after out-of-hospital cardiac arrest (OHCA) with an initial rhythm of non-shockable (Class IIb). It is unknown whether the post-cardiac arrest care for patients with non-shockable cardiac arrest contributed to favorable neurological outcome. The aim of the present study was to clarify the effects of the 2010 guidelines in patients with ROSC after cardiac arrest due to non-shockable rhythm, using the data of the All-Japan Utstein Registry, a prospective, nationwide, population-based registry of OHCA. Methods: From the data of this registry between 2005 and 2015, we included adult patients with ROSC after out-of-hospital non-shockable cardiac arrest due to cardiac etiology. Study patients were divided into three groups based on the different CPR guidelines; the era of the 2000 guidelines (2000G), the era of the 2005 guidelines (2005G), and the era of the 2010 guidelines (2010G). The endpoint was favorable neurological outcome at 30 days after OHCA. Results: The 31,204 patients who met the inclusion criteria comprised 25,045 with ROSC before arrival at the hospital and 6,259 with ROSC after hospital arrival without prehospital ROSC. Figure showed favorable neurological outcome at 30 days in the three groups. Moreover, multivariable analysis showed that the 2010 guidelines were an independent predictor of favorable neurological outcome at 30 days after OHCA, respectively (Figure). Conclusion: In the patients with ROSC after out-of-hospital non-shockable cardiac arrest, the 2010 guidelines were superior to the 2005 guidelines and the 2000 guidelines, in terms of neurological benefits.

Background: The 2015 cardiopulmonary resuscitation (CPR) guidelines have stressed that high-quality CPR improves survival from cardiac arrest (CA). In particular, the guidelines recommended that it is reasonable for rescuers to perform chest compressions at a rate of 100 to 120/min in adult CA patients. However, it is unknown whether the 2015 guidelines contributed to favorable neurological outcome in adult CA patients. The present study aimed to clarify the effects of the 2015 guidelines in adult CA patients, using the data of the All-Japan Utstein Registry, a prospective, nationwide, population-based registry of out-of-hospital CA (OHCA). Methods: From the data of this registry between 2011 and 2016, we included adult witnessed OHCA patients due to cardiac etiology, who had non-shockable rhythm, PEA and asystole, as an initial rhythm. Study patients were divided into two groups based on the different CPR guidelines; the era of the 2010 guidelines (2010G), and the era of the 2015 guidelines (2015G). The endpoint was the favorable neurological outcome at 30 days after OHCA. Results: The 109,175 patients who met the inclusion criteria comprised 18,764 who received CPR based on 2015G and 90,411 who received CPR based on 2010G. The figure showed favorable neurological outcomes at 30 days in the two groups. In the multivariate analysis, the adjusted odds ratio for 30-day favorable neurological outcome in 2015G patients as compared to 2010G patients was 1.28 (95%CI 1.11-1.46, p<0.001). Conclusion: In the OHCA patients with non-shockable rhythm, the 2015 guidelines were superior to the 2010 guidelines, in terms of neurological benefits.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Out-of-hospital cardiac arrest (OHCA) is a major public health challenge and although rate of intrahospital survival increased over the last 40 years, it still remains poor (from 8,6% in 1976-1999 to 9,9% in 2000-2019). Different studies report that introduction of mild therapeutic hypothermia (TTM) improves survival and neurological outcome in comatose patients after OHCA.  Purpose The aim of this research was to evaluate influence of pre-hospital predictors related to cardiopulmonary resuscitation (CPR), neurological status and ECG changes at admission and early percutaneous coronary intervention (PCI) performed within 24h of admission on intrahospital survival and neurological outcome of OHCA patients. Methods The research was conducted as a retrospective cohort study of data taken from the hospital registry on OHCA from January 2007 until November 2019. The analyzed factors were: bystander CPR, duration of CPR until return of ROSC, initial rhythm, responsiveness upon admission defined as Glasgow Coma Score (GCS)&gt;8, presence of ST segment elevation (STEMI) on electrocardiography (ECG) and early PCI. The favorable neurological outcome was defined as a cerebral performance category scale (CPC)≤2. Results The research included 506 survivors of OHCA. Cardiac arrest was witnessed in 412 (81.4%), bystander CPR was performed in 197 (38.9%), CPR lasted ≤20min in 291 (57.5%), initial rhythm was shockable in 304 (60.1%) of patients. At admission 387 (76.5%) were comatose (GCS &lt; 8) and TTM was introduced in 177 (45.7%) of patients. ECG upon admission showed STEMI in 176 (34.8%) and early PCI was performed in 145 (28.6%) of patients. In-hospital mortality in our study group was 281 (55.5%) and 185 (36.6%) of patients had favorable neurological outcome. Multivariate regression analysis showed that initial shockable rhythm (OR 3.391 [2.310-4.977], p &lt; 0.0005), early PCI (OR 0.368 [0.226-0.599], p &lt; 0.0005), duration of CPR ≤20min (OR 4.249 [2.688-6.718], p &lt; 0.0005) and GCS &gt; 8 (OR 0.194 [0.110-0.343], p &lt; 0.0005) were independent predictors of in-hospital survival. Independent predictors of favorable neurological outcome were: initial shockable rhythm (OR 3.301 [2.002-5.441], p&lt; 0.0005), STEMI on ECG upon admission (OR 0.528 [0.326-0.853], p = 0.009), duration of CPR ≤20min (OR 5.144 [3.090-8.565], p&lt; 0.0005) and GCS &gt; 8 (OR 0.152 [0.088-0.260], p&lt; 0.0005). Introduction of TTM improved both intrahospital survival (54.1% vs. 24.4%; p &lt; 0.0005) and neurological outcome (33.5% vs. 11.6%; p &lt; 0.0005) in patients with initial shockable rhythm. Conclusion In our study group of OHCA patients of any origin, initial shockable rhythm, duration of CPR ≤20min and GCS &gt; 8 at admission influenced both intrahospital survival and favorable neurological outcome. Introduction of TTM significantly improved both survival and neurological outcome in comatose patients with initial shockable rhythm.

Introduction: Prehospital variables associated with neurologically intact survival in elderly survivors after out-of-hospital cardiac arrest (OHCA) are unclear and could differ according to age. Methods: We evaluated 6,349 elderly patients with OHCA (age ≥ 65 years) of cardiac origin who achieved prehospital return of spontaneous circulation (ROSC) and survived for at least 1-month after OHCA. Data were obtained from the prospectively recorded All-Japan Utstein Registry between 2011 and 2016. Patients witnessed by emergency medical service providers were excluded. The primary outcome was 1-month neurologically intact survival, defined as a cerebral performance category (CPC) score of 1-2. Patients were divided into three groups by age (65-74, 75-89, or ≥ 90 years). The time from call receipt to ROSC was calculated. Results: The rates of 1-month CPC 1-2 in patients aged 65-74, 75-89, and ≥ 90 years were 66.5% (2,079/3,125), 52.9% (1,557/2,943), and 42.7% (120/281), respectively (p for trend < 0.001). In multivariate logistic regression analysis, initial shockable rhythm and witnessed arrest were significantly associated with 1-month CPC 1-2 for all age groups (Table). However, the presence of bystander cardiopulmonary resuscitation (CPR) was significantly associated with 1-month CPC 1-2 only for patients aged 65-74 years. Time from call receipt to ROSC was not associated with 1-month CPC 1-2 for patients aged ≥ 90 years. In recursive partitioning analysis, the best single predictor for 1-month CPC 1-2 was initial shockable rhythm for all age groups. The next predictor for patients aged 65-74 years with initial shockable rhythm was the presence of bystander CPR, whereas the witnessed arrest was the next predictor for patients aged 65-74 years with initial non-shockable rhythm and other age groups regardless of the initial rhythm. Conclusions: Prehospital variables associated with neurologically intact survival in elderly survivors after OHCA varied with age.

Background: The 2010 guidelines have stressed that systematic post-cardiac arrest care after return of spontaneous circulation (ROSC) can improve the likelihood of patient survival with good neurological outcome. Especially, the 2010 guidelines recommended that comatose adult patients with ROSC after out-of-hospital ventricular fibrillation (VF) cardiac arrest should be induced therapeutic hypothermia (Class I). However, it is unknown whether the post-cardiac arrest care which was recommended by the 2010 guidelines contributed to favorable neurological outcome. The aim of the present study was to clarify the effects of the 2010 guidelines in patients with ROSC after cardiac arrest due to shockable rhythm, using the data of the All-Japan Utstein Registry, a prospective, nationwide, population-based registry of out-of-hospital cardiac arrest (OHCA). Methods: From the data of this registry between 2005 and 2015, we included adult patients with ROSC after out-of-hospital shockable cardiac arrest due to cardiac etiology. Study patients were divided into three groups based on the different CPR guidelines; the era of the 2000 guidelines (2000G), the era of the 2005 guidelines (2005G), and the era of the 2010 guidelines (2010G). The primary endpoint was favorable neurological outcome at 30 days after OHCA. Results: The 30,518 patients who met the inclusion criteria comprised 24,729 with ROSC before arrival at the hospital and 5,789 with ROSC after hospital arrival without prehospital ROSC. Figure showed favorable neurological outcome at 30 days in the three groups. Moreover, multivariable analysis showed that the 2010 guidelines were an independent predictor of favorable neurological outcome at 30 days after OHCA, respectively (Figure). Conclusion: In the patients with ROSC after out-of-hospital shockable cardiac arrest, the 2010 guidelines were superior to the 2005 guidelines and the 2000 guidelines, in terms of neurological benefits.

Introduction: We have reported previously a favorable neurological outcome by extracorporeal cardiopulmonary resuscitation (ECPR) for out of hospital cardiac arrest. However, effects of ECPR on patients with prolonged pulseless electrical activity (PEA) are unclear. We analyzed etiology of patients with favorable neurological outcomes after ECPR for PEA with witness. Methods: In this single center retrospective study, from January 2007 to May 2018, we identified 68 patients who underwent ECPR for PEA with witness. Of these, 13 patients (19%) had good neurological outcome at 1 month (Glasgow-Pittsburgh Cerebral Performance Category (CPC):1-2, Group G), and 55 patients (81%) had unfavorable neurological outcome (CPC:3-5, Group B). We compared courses of treatment and causes/places of arrests between two groups. Results are expressed as mean ± SD. Results: Patient characteristics were not different between the two groups. Time intervals from collapse to induction of V-A ECMO were also not significantly different (Group G; 46.1 ± 20.2 min vs Group B; 46.8 ± 21.7 min, p=0.92). Ten patients achieved favorable neurological outcome among 39 (26%) with non-cardiac etiology. In cardiac etiology, only 3 of 29 patients (9%) had a good outcome at 1 month (p=0.08). In particular, 5 patients of 10 pulmonary embolism, and 4 of 4 accidental hypothermia responded well to ECPR with a favorable neurological outcome. Additionally, 6 of 13 (46%), who had in hospital cardiac arrest, had good outcome, whereas 7 of 55 (15%) who had out of hospital cardiac arrest, had good outcome (p=0.02). Conclusions: In our small cohort of cardiac arrest patients with pulmonary embolism or accidental hypothermia and PEA with witness, EPCR contributed to favorable neurological outcomes at 1 month.

AimsThe purpose of this study was to develop a practical risk−score to predict poor neurological outcome after out−of−hospital cardiac arrest (OOHCA) for use on arrival to a Heart Attack Centre.Methods and ResultsBetween May 2012 and December 2017, 1055 patients had OOHCA in our region, of whom 373 patients were included in the King's Out of Hospital Cardiac Arrest Registry (KOCAR). We performed prediction modelling with multi-variable logistic regression to identify factors independently predictive of the primary outcome in order to derive a risk score. This was externally validated in two independent cohorts comprising 474 patients. The primary outcome was poor neurological function at 6−month follow−up (Cerebral Performance Category 3-−). Seven independent variables for prediction of outcome were identified: Missed (Unwitnessed) arrest, Initial non-shockable rhythm, non-Reactivity of pupils, Age, Changing intra-arrest rhythms, Low pH<;7.20 and Epinephrine administration. From these variables, the MIRA2CLE2 score was developed which had an AUC of 0.90 in the development and 0.85 and 0.89 in the validation cohorts. 3 risk groups of the MIRA2CLE2 were defined − Low risk (≤2−5.6% risk of poor outcome; Intermediate risk (3−4−55.4% of poor outcome) and high risk (≥5−92.3% risk of poor outcome). The risk-score performance was equivalent in a sub-group of patients referred for early angiography and revascularisation where appropriate.ConclusionsThe MIRA2CLE2 score is a practical risk score for early accurate prediction of poor neurological outcome after OOHCA, which has been developed for simplicity of use on admission to a Heart Attack Centre.

Backgrounds: The population of elderly people aged 65 years or older in 2014 is 33 million, and the aging rate (proportion of the total population) is 26.0% in Japan. Victims facing to out of hospital cardiac arrest (OHCA) are getting older and older. Emergency medical system (EMS) in Japan must do the same resuscitation protocols once called to the patient with OHCA, even when he or she is very old and activity of daily life is very low. We need to clarify whether same resuscitation protocols are required to very highly aged patients with OHCA or not. Methods and Results: From January 2005 through December 2014, we conducted a prospective, population-based, observational study involving the consecutive patients across Japan who had OHCA (n= 1,299,784). The percentage of patients with OHCA aged more than 80 years old was increasing from 37.1% in 2005 to 47.8% in 2014 by 1% each year. Survival at one month after OHCA with cerebral performance category (CPC) scale 1 or 2 were 4,368 out of total 318,590 OHCA (1.4%) in 80’s, 1043 out of 126,546 (0.8%) in 90’s, and 35 out of 5,544 (0.6%) in aged more than 100 (from 100 to 114). Survival at one month after OHCA with CPC scale 1 or 2 was 11.084 out of 234,366 (4.7%) in 50- 60’s. Patients with witnessed OHCA with shockable rhythm and by-stander CPR survived to CPC 1 or 2 at one month after OHCA were 8.0% in 80’s, 4.1% in 90’s, 0 in aged more than 100, and 22.2% in 50-60’s respectably. Conclusion: Number of survivors with CPC 1 or 2 were very few in patients with OHCA aged more than 80 years old, but still existed. Although the same resuscitation protocols are needed for highly aged victims with OHCA, another system which arrow EMS to stop resuscitation should be established in the highly aging society.

Background: Prolonged conventional cardiopulmonary resuscitation (C-CPR) is associated with a poor prognosis in out-of-hospital cardiac arrest (OHCA) patients. Extracorporeal cardiopulmonary resuscitation (E-CPR) has been utilized as a rescue strategy for patients with cardiac arrest unresponsive to C-CPR. However, the indication and optimal duration to switch from C-CPR to E-CPR are not well established. In addition, the opportunities to develop teamwork skills and expertise to mitigate risks are few. We thus developed the implementation protocol for the E-CPR simulation program, and investigated whether the faster deployment of extracorporeal membrane oxygenation (ECMO) improves the neurological outcome in patients with refractory OHCA. Methods: A total of 42 consecutive patients (age 58±16 years, male ratio 90%, and initial shockable rhythm 64%) received E-CPR (3% of OHCA) during the study period. Among them, 32 (76%) were deployed ECMO during the pre-intervention time period (Pre: from January 2012 to September 2017), whereas 10 (24%) were deployed during the post-intervention time period (Post: October 2017 to May 2019). We compared the door to E-CPR time, collapse to E-CPR time, 30-day mortality, and favorable neurological outcome (Cerebral Performance Categories 1, 2) between the two periods. Results: There was no significant difference in age, the rates of male sex and shockable rhythm, and the time form collapse to emergency room admission between the two periods. The door to E-CPR time and the collapse to E-CPR time were significantly shorter in the post-intervention period compared to the pre-intervention period (Pre: 39 min [IQR; 30-50] vs. Post: 29 min [IQR; 22-31]; P=0.007, Pre: 76 min [IQR; 58-87] vs. Post: 59 min [IQR; 44-68]; P=0.02, respectively). The 30-day mortality was similar between the two periods (Pre: 88% vs. Post: 80%; P=0.6). In contrast, the rate of favorable neurological outcome at the time of discharge was significantly higher in post-intervention period (Pre: 0% vs. Post: 20%; P=0.01) compared to the pre-intervention period. Conclusion: A comprehensive simulation-based training for E-CPR seems to improve the neurological outcome in patients with refractory OHCA patients.

Background: Delay in administration of the first epinephrine dose has been shown to be associated with a lower chance of good outcome in adult, in-hospital, non-shockable cardiac arrest. Whether this association is true in pediatric in-hospital non-shockable cardiac arrest remains unknown. Methods: We utilized the Get With the Guidelines - Resuscitation national registry to identify pediatric patients (age < 18 years) with an in-hospital cardiac arrest between 2000 and 2010. We included patients with an initial non-shockable rhythm who received at least one dose of epinephrine. To assess the association between time to epinephrine administration and survival to discharge we used multivariate logistic regression models with adjustment for multiple predetermined variables including age, gender, illness category, pre-existing mechanical ventilation, monitored, witnessed, location, time of the day/week, year of arrest, insertion of an airway, initial rhythm, time to initiation of cardiopulmonary resuscitation, hospital type and hospital teaching status. Secondary outcomes included return of spontaneous circulation (ROSC) and neurological outcome. Results: 1,131 patients were included. Median age was 9 months (quartiles: 21 days - 6 years) and 46% were female. Overall survival to hospital discharge was 29%. Longer time to epinephrine was negatively associated with survival to discharge in multivariate analysis (OR: 0.94 [95%CI: 0.90 - 0.98], per minute delay). Longer time to epinephrine was negatively associated with ROSC (OR: 0.93 [95%CI: 0.90 - 0.97], per minute delay) but was not statistically significantly associated with survival with good neurological outcome (OR: 0.95 [95%CI: 0.89 - 1.03], per minute delay). Conclusions: Delay in administration of epinephrine during pediatric in-hospital cardiac arrest with a non-shockable rhythm is associated with a lower chance of ROSC and lower survival to hospital discharge.
