Background: While survival after in-hospital cardiac arrest (IHCA) has improved in recent years, it remains unknown whether this trend primarily applies to younger IHCA victims or extends to older patients as well. The aim of this study was to assess trends in survival to hospital discharge after adult IHCA across age groups from 2000 to 2016. Methods: This is an observational study of IHCA patients included in the Get With The Guidelines®-Resuscitation registry between January 2000 and December 2016. The primary outcome was survival to hospital discharge, while secondary outcomes included rates of return of spontaneous circulation (ROSC) and neurological outcome at discharge. Patients were stratified into five age groups: < 50 years, 50-59 years, 60-69 years, 70-79 years, and ≥80 years. Generalized linear regression was used to obtain absolute survival rates over time. Analyses of interaction were included to assess differences in survival trends between age groups. Results: A total of 234,767 IHCA patients were included for the analyses. The absolute increase in survival per calendar year was 0.8% (95%CI 0.7 - 1.0%, p < 0.001) for patients younger than 50 years, 0.6% (95%CI 0.4 - 0.7%, p < 0.001) for patients between 50 and 59 years, 0.5% (95%CI 0.4 - 0.6%, p < 0.001) for patients between 60 and 69 years, 0.5% (95%CI 0.4 - 0.6%, p < 0.001) for patients between 70 and 79 years, and 0.5% (95%CI 0.4 - 0.6%, p < 0.001) for patients older than 80 years. Further, a significant increase in both rates of ROSC and survival with a good neurological outcome was seen for all age groups. In both unadjusted and adjusted analyses of survival, we observed a significant interaction between calendar year and age group ( p < 0.001), indicating that the rate of improvement in survival over time was significantly different between age groups. Conclusions: For patients with IHCA, survival to discharge, ROSC, and survival to discharge with a good neurological outcome have improved significantly from 2000 to 2016 for all age groups.

Introduction: Agonal respiration has been shown to be commonly associated with witnessed events, ventricular fibrillation, and increased survival during out-of-hospital cardiac arrest. There is little information on incidence of gasping for in-hospital cardiac arrest (IHCA). Our “Rapid Response Team” (RRT) missions were monitored between December 2010 and March 2015, and the prevalence of gasping and survival data for IHCA were investigated. Methods: A standardized extended in-hospital Utstein data set of all RRT-interventions occurring at the University Hospital Basel, Switzerland, from December 13, 2010 until March 31, 2015 was consecutively collected and recorded in Microsoft Excel (Microsoft Corp., USA). Data were analyzed using IBM SPSS Statistics 22.0 (IBM Corp., USA), and are presented as descriptive statistics. Results: The RRT was activated for 636 patients, with 459 having a life-threatening status (72%; 33 missing). 270 patients (59%) suffered IHCA. Ventricular fibrillation or pulseless ventricular tachycardia occurred in 42 patients (16% of CA) and were associated with improved return of spontaneous circulation (ROSC) (36 (97%) vs. 143 (67%; p<0.001)), hospital discharge (25 (68%) vs. 48 (23%; p<0.001)), and discharge with good neurological outcome (Cerebral Performance Categories of 1 or 2 (CPC) (21 (55%) vs. 41 (19%; p<0.001)). Gasping was seen in 128 patients (57% of CA; 46 missing) and was associated with an overall improved ROSC (99 (78%) vs. 55 (59%; p=0.003)). In CAs occurring on the ward (154, 57% of all CAs), gasping was associated with a higher proportion of shockable rhythms (11 (16%) vs. 2 (3%; p=0.019)), improved ROSC (62 (90%) vs. 34 (55%; p<0.001)), and hospital discharge (21 (32%) vs. 7 (11%; p=0.006)). Gasping was not associated with neurological outcome. Conclusions: Gasping was frequently observed accompanying IHCA. The faster in-hospital patient access is probably the reason for the higher prevalence compared to the prehospital setting. For CA on the ward without continuous monitoring, gasping correlates with increased shockable rhythms, ROSC, and hospital discharge.

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.

Introduction: How long resuscitation attempts should be continued before termination of efforts is not clear in patients with out-of-hospital cardiac arrest (OHCA). We studied outcomes in patients with return of spontaneous circulation (ROSC) across quartiles of time from 9-1-1 call to ROSC. Hypothesis: Survival with favorable neurological outcome is seen in all time intervals from 9-1-1 call to ROSC. Methods: Using data from Resuscitation Outcomes Consortium (ROC) Prehospital Resuscitation clinical trials: IMpedance valve and an Early vs. Delayed analysis (PRIMED) available via National Institute of Health, patients with ROSC not witnessed by the emergency medical service (EMS) were identified and grouped by quartiles of time from 9-1-1 call to ROSC. We defined favorable neurological outcome as modified Rankin Scale (mRS) scores of ≤3. Results: Included were 3,431 OHCA patients with ROSC. Median time from 9-1-1 call to ROSC was 22.8 min (25%-75% 17 min–29.2 min); 953 (27.8%) survived to discharge (20.4% mRS ≤3). Significant survival and favorable neurological outcome were seen in each quartile (Figure). In patients who received bystander cardiopulmonary resuscitation (CPR), survival rates were 60.9%, 33.2%, 18.3% and 11.1% across quartiles of time to ROSC versus (vs.) 51.5%, 25.6%, 13.3% and 8.9% in patients without bystander CPR; corresponding rates of favorable neurological outcome were 50.7%, 23.8%, 12.2% and 9.1% vs. 40.1%, 16.6%, 8% and 4.8%. Correspondingly, survival rates in defibrillated patients were 70.1%, 45.9%, 25.5% and 16.4% vs. 36.3%, 9.5%, 6% and 3.4% in non-defibrillated patients; corresponding rates of favorable neurological outcome were 59.8%, 33.4%, 18.3% and 11.4% vs. 24.4%, 4.1%, 1.9% and 1.8%. Conclusions: Survival with favorable neurological outcome was seen in all quartiles of time to ROSC, even in cases without bystander CPR or shocks delivered. This suggests that EMS personnel should not terminate resuscitation efforts too early.

In out-of-hospital cardiac arrest (OHCA), the occurrence of temporary periods of return to spontaneous circulation (t-ROSC) has been found to be predictive of survival to hospital discharge. The relationship between the duration of t-ROSCs and OHCA outcome has not been explored yet. The aim of this prospective observational study was to analyze the duration of t-ROSCs during OHCA and its impact on outcome. Defibrillator-recorded OHCA events were analyzed via dedicated software. The number of t-ROSC episodes and their overall durations were recorded. The study endpoint was the good neurologic outcome at hospital discharge. Among 285 patients included in the study, 45 (15.8%) had one or more t-ROSCs. The likelihood of t-ROSC occurrence was higher in patients with a shockable rhythm (p = 0.009). The cumulative length of t-ROSC episodes was significantly higher for patients who achieved sustained ROSC (p < 0.001). The adjusted cumulative t-ROSC length was an independent predictor for good neurological outcome at hospital discharge (OR 1.588, 95% CI 1.017 to 2.481; p = 0.042). According to our findings and data from previous studies, t-ROSC episodes during OHCA should be considered as a favorable prognostic factor, encouraging continuing resuscitative efforts.

Introduction: One in nine (11.7%) people in Saskatchewan identifies as First Nations. In Canada, First Nations people experience a higher burden of cardiovascular disease when compared to the general population, but it is unknown whether they have different outcomes in out of hospital cardiac arrest (OHCA). Methods: We reviewed pre-hospital and inpatient records of patients sustaining an OHCA between January 1st, 2015 and December 31st, 2017. The population consisted of patients aged 18 years or older with OHCA of presumed cardiac origin occurring in the catchment area of Saskatoon's EMS service. Variables of interest included, age, gender, First Nations status (as identified by treaty number), EMS response times, bystander CPR, and shockable rhythm. Outcomes of interest included return of spontaneous circulation (ROSC), survival to hospital admission, and survival to hospital discharge. Results: In all, 372 patients sustained OHCA, of which 27 were identified as First Nations. First Nations patients with OHCA tended to be significantly younger (mean age 46 years vs. 65 years, p &lt; 0.0001) and had shorter EMS response times (median times 5.3 minutes vs. 6.2 minutes, p = 0.01). There were no differences between First Nations and non-First Nations patients in terms of incidence of shockable rhythms (24% vs. 26%, p = 0.80), ROSC (42% vs. 41%, p = 0.87), survival to admission (27% vs 33%, p = 0.53), and survival to hospital discharge (15% vs. 12%, p = 0.54). Conclusion: In Saskatoon, First Nations patients sustaining OHCA appear to have similar survival rates when compared with non-First Nations patients, suggesting similar baseline care. Interestingly, First Nations patients sustaining OHCA were significantly younger than their non-First Nations counterparts. This may reflect a higher burden of cardiovascular disease, suggesting a need improved prevention strategies.

Introduction: The association between chest compression (CC) pause duration and pediatric in-hospital cardiac arrest (IHCA) survival outcomes is unknown. We hypothesized that longer maximum CC pause durations are associated with worse survival and neurological outcomes. Methods: Cohort study of all index pediatric IHCAs (<18 years of age) ≥1 min in the Pediatric Resuscitation Quality (PediRES-Q) Network from July 2015 through December 2019. We used multivariate logistic regression with mixed effects and robust standard errors to analyze association of 5-sec increments of longest CC pause duration with survival and neurologic outcomes. Favorable neurological outcome was defined as Pediatric Cerebral Performance Category (PCPC) at discharge ≤3 or no change from baseline. Results: We identified 371 index IHCAs: median [Q1,Q3] age 2.6 [0.6,9.4] years, female 46%, shockable rhythm 13%, CPR duration 23 [9,47] min. Median length of the longest pause was 17 [8,27] sec. Each 5 sec increase in longest CC pause duration was associated with 6% lower odds for survival with favorable neurological outcome, even after adjusting for age, defibrillation, intubation, extracorporeal CPR, illness category, hypotension as etiology for arrest, CC depth, and clustering by site (aOR 0.94 [95% CI:0.88-0.99], p=0.04). Analyses controlling for the same factors demonstrated an association of longest pause duration with lower odds for survival to hospital discharge (aOR 0.94 [95% CI: 0.90-0.99, p=0.02) and return of spontaneous circulation (aOR 0.91 [(95% CI: 0.86-0.96], p=0.001). Conclusions: Longest CC pause duration is associated with favorable neurological outcome, survival to hospital discharge, and return of spontaneous circulation following pediatric IHCA, even when controlling for known confounders and clustering by site. Each 5 sec. increment in longest CC pause duration was associated with 6% lower odds for survival with favorable neurological outcome.

Objectives: The purpose of this study was to analyze the effect of cardiac arrest recognition by emergency medical dispatch on the pre-hospital advanced cardiac life support and to investigate the outcome of out-of-hospital cardiac arrest. Method: This study was conducted to evaluate the out-of-hospital cardiac arrest patients over 18 years of age, excluding trauma and poisoning patients, from 1 August 2015 to 31 July 2016. We investigated whether it was a cardiac-arrest recognition at dispatch. We compared the pre-hospital return of spontaneous circulation, the rate of survival admission and discharge, good neurological outcome, and also analyzed the time of securing vein, time of first epinephrine administration, and arrival time of paramedics. Results: A total of 3695 out-of-hospital cardiac arrest patients occurred during the study period, and 1468 patients were included in the study. Resuscitation rate by caller was significantly higher in the recognition group. The arrival interval between the first and second emergency service unit was shorter as 5.1 min on average, and the connection rate of paramedics and physicians before the arrival was 32.3%, which was significantly higher than that of the unrecognized group. The mean time required to first epinephrine administration was 13.1 min, which was significantly faster in the recognition group. However, there was no statistically significant difference between the two groups in patients with good neurological outcome, and rather the rate of return of spontaneous circulation and survival discharge was significantly higher in the non-recognition group. Conclusion: Although the recognition of cardiac arrest at dispatch does not directly affect survival rate and good neurological outcome, the activation of pre-hospital advanced cardiac life support and the shortening the time of epinephrine administration can increase pre-hospital return of spontaneous circulation. Therefore, effort to increase recognition by dispatcher is needed.

Abstract Background Mechanical circulatory support (MCS) with either extracorporeal membrane oxygenation or Impella has shown potential as a salvage therapy for patients with refractory out-of-hospital cardiac arrest (OHCA). The objective of this study was to describe the gradual implementation, survival and adherence to the national consensus with respect to use of MCS for OHCA in Denmark, and to identify factors associated with outcome. Methods This retrospective, observational cohort study included patients receiving MCS for OHCA at all tertiary cardiac arrest centers (n = 4) in Denmark between July 2011 and December 2020. Logistic regression and Kaplan–Meier survival analysis were used to determine association with outcome. Outcome was presented as survival to hospital discharge with good neurological outcome, 30-day survival and predictors of 30-day mortality. Results A total of 259 patients were included in the study. Thirty-day survival was 26%. Sixty-five (25%) survived to hospital discharge and a good neurological outcome (Glasgow–Pittsburgh Cerebral Performance Categories 1–2) was observed in 94% of these patients. Strict adherence to the national consensus showed a 30-day survival rate of 30% compared with 22% in patients violating one or more criteria. Adding criteria to the national consensus such as signs of life during cardiopulmonary resuscitation (CPR), pre-hospital low-flow < 100 min, pH > 6.8 and lactate < 15 mmol/L increased the survival rate to 48%, but would exclude 58% of the survivors from the current cohort. Logistic regression identified asystole (RR 1.36, 95% CI 1.18–1.57), pulseless electrical activity (RR 1.20, 95% CI 1.03–1.41), initial pH < 6.8 (RR 1.28, 95% CI 1.12–1.46) and lactate levels > 15 mmol/L (RR 1.16, 95% CI 1.16–1.53) as factors associated with increased risk of 30-day mortality. Patients presenting signs of life during CPR had reduced risk of 30-day mortality (RR 0.63, 95% CI 0.52–0.76). Conclusions A high survival rate with a good neurological outcome was observed in this Danish population of patients treated with MCS for OHCA. Stringent patient selection for MCS may produce higher survival rates but potentially withholds life-saving treatment in a significant proportion of survivors.

Purpose: Targeted temperature management (TTM) is a standard of care in patients after cardiac arrest for neuroprotection. Currently, the effectiveness and efficacy of TTM after extracorporeal cardiopulmonary resuscitation (ECPR) is unknown. We aimed to compare neurological and survival outcomes between TTM vs non-TTM in patients undergoing ECPR for refractory cardiac arrest. Methods: We searched PubMed and 5 other databases for randomized controlled trials and observational studies reporting neurological outcomes or survival in adult patients undergoing ECPR with or without TTM. Good neurological outcome was defined as cerebral performance category <3. Two independent reviewers extracted the data. Random-effects meta-analyses were used to pool data. Results: We included 35 studies (n = 2,643) with the median age of 56 years (interquartile range [IQR]: 52-59). The median time from collapse to ECMO cannulation was 58 minutes (IQR: 49-82) and the median ECMO duration was 3 days (IQR: 2.0-4.1). Of 2,643, 1,329 (50.3%) patients received TTM and 1,314 (49.7%) did not. There was no difference in the frequency of good neurological outcome at any time between TTM (29%, 95% confidence interval [CI]: 23%-36%) vs. without TTM (19%, 95% CI: 9%-31%) in patients with ECPR ( P = 0.09). Similarly, there was no difference in overall survival between patients with TTM (30%, 95% CI: 22%-39%) vs. without TTM (24%, 95% CI: 14%-34%) ( P = 0.31). A cumulative meta-analysis by publication year showed improved neurological and survival outcomes over time. Conclusions: Among ECPR patients, survival and neurological outcome were not different between those with TTM vs. without TTM. Our study suggests that neurological and survival outcome are improving over time as ECPR therapy is more widely used. Our results were limited by the heterogeneity of included studies and further research with granular temperature data is necessary to assess the benefit and risk of TTM in ECPR population.
