Hospital Characteristics

Objective Hospital characteristics, such as hospital type and admission time, have been reported to be associated with survival in adult out-of-hospital cardiac arrest (OHCA) patients. However, findings regarding the effects of hospital types on pediatric OHCA patients have been limited. The aim of this study was to analyze the relationship between the hospital characteristics and the outcomes of pediatric OHCA patients. Methods This study was a retrospective secondary analysis of the Japanese Association for Acute Medicine-out-of-hospital cardiac arrest registry. The period of this study was from 1 June 2014 to 31 December 2015. We enrolled all pediatric patients (those 0–17 years of age) experiencing OHCA in this study. We enrolled all types of OHCA. The primary outcome of this study was 1-month survival after the onset of cardiac arrest. Results We analyzed 310 pediatric patients (those 0–17 years of age) with OHCA. In survivors, the rate of witnessed arrest and daytime admission was significantly higher than nonsurvivors (56% vs. 28%, p < 0.001: 49% vs. 31%; p = 0.03, respectively). The multiple logistic regression model showed that daytime admission was related to 1-month survival (odds ratio, OR: 95% confidence interval, CI, 3.64: 1.23–10.80) (p = 0.02). OHCA of presumed cardiac etiology and witnessed OHCA were associated with higher 1-month survival. (OR: 95% CI, 3.92: 1.23–12.47, and 6.25: 1.98–19.74, respectively). Further analyses based on the time of admission showed that there were no significant differences in the proportions of patients with witnessed arrest and who received bystander cardiopulmonary resuscitation and emergency medical service response time by admission time. Conclusion Pediatric OHCA patients who were admitted during the day had a higher 1-month survival rate after cardiac arrest than patients who were admitted at night.

Introduction: For pediatric patients with out-of-hospital cardiac arrest (OHCA) who do not achieve return of spontaneous circulation (ROSC), it remains unclear whether patients should be transported to a hospital with ongoing resuscitation or remain on-scene for further resuscitation. We therefore evaluated: (1) the association between intra-arrest transport, with reference to continued on-scene resuscitation, and survival to hospital discharge; and, (2) whether the association differs across the timing of intra-arrest transport. Methods: We conducted a secondary analysis of the Resuscitation Outcomes Consortium Epidemiologic Registry. We included pediatrics (<18 years) with emergency medical services (EMS)-treated OHCA between 2005 and 2015. Our exposure of interest was intra-arrest transport, defined as transport to a hospital prior to ROSC. Patients who had intra-arrest transport at any minute after EMS arrival underwent risk-set matching with patients who had continued on-scene resuscitation within the same minute using time-dependent propensity score calculated from patient demographics, arrest characteristics, and EMS interventions. We repeated the main analysis with 5-minute strata by the time of matching. Results: Of 2,854 included patients, the median age was 1 year (IQR, 0-9), 59.3% were male, 9.8% were public location, 22.1% were bystander witnessed, 6.0% had initial shockable rhythms, and 66.3% underwent intra-arrest transport at a median of 15 minutes (IQR 9-22) after EMS arrival. In the propensity-matched cohort including 2,080 patients, 5.5 % (57/1040) in intra-arrest transport group and 5.9% (61/1040) in continued on-scene resuscitation group had survival to hospital discharge (risk ratio [RR]=0.94, 95% CI 0.65-1.37). We did not detect an association within the time-based strata: 0-5 minutes (RR=0.74, 95% CI 0.19-2.85), 5-10 minutes (RR=0.52, 95% CI 0.23-1.16), 10-15 minutes (RR=1.13, 95% CI 0.58-2.22), 15-20 minutes, (RR=1.70, 95% CI 0.78-3.71), or >20 minutes (RR=0.73, 95% CI 0.32-1.63) after EMS arrival. Conclusions: Among pediatric patients with OHCA, intra-arrest transport was not associated with survival to hospital discharge. The findings persisted across the timing of intra-arrest transport.

High-quality cardiopulmonary resuscitation (CPR) is a key element in out-of-hospital cardiac arrest (OHCA) resuscitation. Mechanical CPR devices have been developed to provide uninterrupted and high-quality CPR. Although human studies have shown controversial results in favor of mechanical CPR devices, their application in pre-hospital settings continues to increase. There remains scant data on the pre-hospital use of mechanical CPR devices in Asia. Therefore, we conducted a retrospective cohort study between September 2018 and August 2020 in an urban city of Taiwan to analyze the effects of mechanical CPR devices on the outcomes of OHCA; the primary outcome was attainment of return of spontaneous circulation (ROSC). Of 552 patients with OHCA, 279 received mechanical CPR and 273 received manual CPR, before being transferred to the hospital. After multivariate adjustment for the influencing factors, mechanical CPR was independently associated with achievement of any ROSC (OR = 1.871; 95%CI:1.195–2.930) and sustained (≥24 h) ROSC (OR = 2.353; 95%CI:1.427–3.879). Subgroup analyses demonstrated that mechanical CPR is beneficial in shorter emergency medical service response time (≤4 min), witnessed cardiac arrest, and non-shockable cardiac rhythm. These findings support the importance of early EMS activation and high-quality CPR in OHCA resuscitation.

Abstract Background: Futile resuscitation for out-of-hospital cardiac arrest (OHCA) patients in the coronavirus disease (COVID)-19 era can lead to risk of disease transmission and unnecessary transport. Various existing basic or advanced life support (BLS or ALS, respectively) rules for the termination of resuscitation (TOR) have been derived and validated in North America and Asian countries. This study aimed to evaluate the external validation of these rules in predicting the survival outcomes of OHCA patients in the COVID-19 era.Methods: This was a multicenter observational study using the WinCOVID-19 Daegu registry data collected during February 18–March 31, 2020. The subjects were patients who showed cardiac arrest of presumed cardiac etiology. The outcomes of each rule were compared to the actual patient survival outcomes. The sensitivity, specificity, false positive value (FPV), and positive predictive value (PPV) of each TOR rule were evaluated. Results: In total, 170 of the 184 OHCA patients were eligible and evaluated. TOR was recommended for 122 patients based on the international basic life support termination of resuscitation (BLS-TOR) rule, which showed 85% specificity, 74% sensitivity, 0.8% FPV, and 99% PPV for predicting unfavorable survival outcomes. When the traditional BLS-TOR rules and KoCARC TOR rule II were applied to our registry, one patient met the TOR criteria but survived at hospital discharge. With regard to the FPV (upper limit of 95% confidence interval <5%), specificity (100%), and PPV (>99%) criteria, only the KoCARC TOR rule I, which included a combination of three factors including not being witnessed by emergency medical technicians, presenting with an asystole at the scene, and not experiencing prehospital shock delivery or return of spontaneous circulation, was found to be superior to all other TOR rules. Conclusion: Among the previous nine BLS and ALS TOR rules, KoCARC TOR rule I was most suitable for predicting poor survival outcomes and showed improved diagnostic performance. Further research on variations in resources and treatment protocols among facilities, regions, and cultures will be useful in determining the feasibility of TOR rules for COVID-19 patients worldwide.

Background Bystander cardiopulmonary resuscitation (CPR) is a critical intervention to improve survival following out‐of‐hospital cardiac arrest. We evaluated the quality of bystander CPR and whether performance varied according to the number of bystanders or provision of telecommunicator CPR (TCPR). Methods and Results We investigated non‐traumatic out‐of‐hospital cardiac arrest occurring in a large metropolitan emergency medical system during a 6‐month period. Information about bystander care was ascertained through review of the 9‐1‐1 recordings in addition to emergency medical system and hospital records to determine bystander CPR status (none versus TCPR versus unassisted), the number of bystanders on‐scene, and CPR performance metrics of compression fraction and compression rate. Of the 428 eligible out‐of‐hospital cardiac arrest, 76.4% received bystander CPR including 43.7% unassisted CPR and 56.3% TCPR; 35.2% had one bystander, 33.3% had 2 bystanders, and 31.5% had ≥3 bystanders. Overall compression fraction was 59% with a compression rate of 88 per minute. CPR differed according to TCPR status (fraction=52%, rate=87 per minute for TCPR versus fraction=69%, rate=102 for unassisted CPR, P <0.05 for each comparison) and the number of bystanders (fraction=55%, rate=87 per minute for 1 bystander, fraction=59%, rate=89 for 2 bystanders, fraction=65%, rate=97 for ≥3 bystanders, test for trend P <0.05 for each metric). Additional bystander actions were uncommon to include rotation of compressors (3.1%) or application of an automated external defibrillator (8.0%). Conclusions Bystander CPR quality as gauged by compression fraction and rate approached guideline goals though performance depended upon the type of CPR and number of bystanders.

Introduction: It is unclear whether prehospital advanced airway management (AAM: endotracheal intubation and supraglottic airway device placement) for pediatric patients with out-of-hospital cardiac arrest (OHCA) improves patient outcomes. Objective: To test the hypothesis that prehospital advanced airway management during pediatric OHCA is associated with patient outcomes. Methods: We conducted a secondary analysis of a nationwide, prospective, population-based OHCA registry in Japan. We included pediatric patients (<18 years) with OHCA in whom emergency medical services (EMS) personnel resuscitated and transported to medical institutions during 2014 and 2015. The primary outcome was one-month survival. Secondary outcome was one-month survival with favorable functional outcome, defined as cerebral performance category score 1 or 2. Patients who received AAM during cardiopulmonary resuscitation by EMS personnel at any given minute were sequentially matched with patients at risk of receiving AAM within the same minutes based on time-dependent propensity score calculated from a competing risk regression model in which we treated prehospital return of spontaneous circulation as a competing risk event. Results: We included 2,548 patients; 1,017 (39.9%) were infants (<1 year), 839 (32.9%) were children (1 year to 12 years), and 692 (27.2%) were adolescents. Of the 2,548, included patients, 336 (13.2%) underwent prehospital AAM during cardiac arrest. In the time-dependent propensity score matched cohort (n = 642), there were no significant differences in one-month survival (AAM: 32/321 [10.0%] vs. no AAM: 27/321 [8.4%]; odds ratio, 1.33 [95% CI, 0.80 to 2.21]) and one-month survival with favorable functional outcome (AAM: 6/321 [1.9%] vs. no AAM: 5/321 [1.6%]; odds ratio, 1.48 [95% CI, 0.41 to 5.40]). Conclusions: Among pediatric patients with OHCA, we found no associations between prehospital AAM and favorable patient outcomes.
