Introduction: Survival for victims of out-of-hospital cardiac arrest (OHCA) is typically between 8 and 12%. We sought to report the trends in survival in British Columbia (BC) over a 10-year period. Methods: The BC Resuscitation Outcomes Consortium prospectively collected detailed prehospital and hospital data on consecutive non-traumatic OHCAs from 2006 to 2016 within BC’s four metropolitan areas. We included EMS-treated adult patients without DNR orders. To describe baseline characteristics we organized patient characteristics in three time periods: 2006-09, 2010-13, and 2014-16 (first and last periods reported below). The primary and secondary endpoints were survival at hospital discharge and return of spontaneous circulation (ROSC). We tested the significance of year-by-year trends in baseline characteristics, and performed multivariable Poisson regression, using calendar year as an independent variable, to calculate risk-adjusted rates for survival. Results: Between January 1, 2006 and March 31, 2016 there were a total of 26 433 non-traumatic OHCAs, with 15 145 included in this study. There were significant decreases in the proportion with initial shockable cardiac rhythms (28% to 23%) and bystander witnessed arrests (42% to 39%), however significant increases in the proportion with bystander CPR (40% to 49%) and ALS treatment (86% to 97%), and the median chest compression fraction (0.81 to 0.87). There was a significant increase in the median time until termination of resuscitation in those who did not achieve ROSC (27 to 32 minutes), and a significant decrease in the proportion of patients who were transported in absence of ROSC (17% to 6.5%). There was a significant improvement in achieving ROSC (44% to 48%; adjusted rate ratio per year 1.02, 95% CI 1.01 to 1.02) and survival at hospital discharge (10% to 14%; adjusted rate ratio per year 1.05, 95% CI 1.04 to 1.06). Both subgroups of initial shockable (adjusted rate ratio per year 1.04, 95% CI 1.03 to 1.05) and non-shockable (adjusted rate ratio per year 1.08, 95% CI 1.06 to 1.12) cardiac rhythms demonstrated survival improvement. Conclusion: Despite a significant decrease in those with initial shockable rhythms, out-of-hospital cardiac arrest survival in BC’s metropolitan regions increased by approximately 40% over a 10-year period. During this time there were system changes and quality of care improvements as provided by bystanders and professionals.

Background: As pediatric out-of-hospital cardiac arrest (OHCA) occurs infrequently, little is known about survival outcomes in children. We examined whether OHCA survival in children differed by patients’ age, sex, and race, as well as recent survival trends. Methods: Within the Cardiac Arrest Registry to Enhance Survival (CARES), a prospective U.S. OHCA registry encompassing 64 million residents, we identified patients less than 18 years of age with an OHCA from October, 2005 to December, 2012. We examined whether survival differed by patients’ age (≤1 year, 1-8 years, >8 years), sex, race, and initial cardiac arrest rhythm, using modified Poisson regression, adjusted for patient characteristics. Similarly, we examined trends in survival, with years 2005-7 as the reference. Results: A total of 1,412 patients with an OHCA were identified, of which 67 (4.7%) were infants, 918 (65.0%) were younger children, and 427 (30.2%) older children. Sixty percent of the study population was male and 33.4% were black. The vast majority of arrests involved a non-shockable rhythm, with only 9.2% of patients having a first documented rhythm of ventricular tachycardia (VT) or ventricular fibrillation (VF). Overall, 103 (7.3%) patients survived to hospital discharge. Of those with non-shockable rhythms (asystole, pulseless electrical activity, and unknown, non-shockable rhythms), 4.4% survived to discharge compared with a survival of 36.2% in those with VT or VF (P<0.001). After adjustment for patient characteristics, children 1-8 years of age were less likely to survive to hospital discharge compared with children >8 years of age (rate ratio [RR]: 0.52; 95% confidence interval [CI]: 0.34, 0.82). In addition, OHCAs due to VT or VF were associated with improved survival (RR 6.67; 95% CI 4.35, 10.23). In contrast, there were no differences in survival by sex or race. Additionally, no temporal trends in survival were observed (p=0.47). Conclusion: In a large, national registry of pediatric OHCA, we found no disparities in survival by patients’ sex, race, or year of arrest, although survival was lower in young children and those with non-shockable cardiac arrest rhythms.

BackgroundA first step to improving outcomes after Out-of-hospital cardiac arrest is to measure the performance of the local ‘Chain of Survival’. Ambulance services routinely report the number of OHCA where resuscitation is attempted, but lack access to outcome data such as survival to hospital discharge. Our novel data linkage project has been developed to inform the implementation of UK’s strategy for OHCA and provide insight into both short- and long-term patient outcomes.MethodsScottish Ambulance Service data was used to identify OHCA incidents where resuscitation was attempted between 2011–2015. OHCA incidents were then probabilistically matched to a range of administrative datasets based on Community Health Index (CHI) linkage. The data were stored and accessed through a Safe Haven where it was used to determine baseline characteristics of the ‘Chain of Survival’ in UK.ResultsAround 3,000 OHCA cases per year were identified with around 6.2% survival to hospital discharge. Of all cases 73.2% could be linked with other datasets such as hospital data (SMR01 and intensive care data), deaths data and SPARRA (comorbidities). This resulted in a rich dataset including a range of demographics, survival and clinical performance measures. Logistic regression models showed that a higher age, male gender and living in a socially deprived area are associated with a higher risk of an OHCA. Higher age and living in a rural or socially deprived area are also associated with an increased mortality risk.ConclusionsOur data set the scene for the implementation of UK’s Strategy for OHCA providing insight into the performance of whole ‘Chain of Survival’. It offers the opportunity to identify priority areas for improvement and track impact of strategy implementation.

Background: Although survival to hospital discharge after in-hospital cardiac arrest (IHCA) has improved over the last decade, it is unknown if these survival gains are sustained after hospital discharge. Accordingly, we evaluated temporal trends in 1-year survival after IHCA. Methods: We linked data from Get With The Guidelines-Resuscitation (a national IHCA registry) with Medicare files and evaluated temporal trends in 1-year survival after IHCA between 2000 and 2011, using multivariable Poisson regression models to account for patient factors, clinical factors, cardiac arrest characteristics (e.g. initial rhythm, location of arrest), and hospital site. We examined 1-year survival trends overall, and separately for shockable (ventricular fibrillation [VF] and pulseless ventricular tachycardia [VT]) and non-shockable rhythms (asystole and pulseless electrical activity [PEA]). Results: Of 45,567 patients with IHCA, the majority had a presenting rhythm of PEA (43.5%) or asystole (42.2%), and half (53.6%) occurred in an ICU. Overall 1-year survival was 9.4%, with higher survival each successive year (FIGURE). Risk-adjusted 1-year survival increased over time for all IHCA (adjusted rate ratio [RR] per year, 1.05; 95% confidence interval [CI], 1.04 to 1.06; P<0.001 for trend) and separately for VT/VF and PEA/asystole arrests (all p for trend <0.001). Compared with 2000-01, 1-year survival after IHCA in 2011 increased by 62% (adjusted RR, 1.62 [95% CI: 1.44-1.81]) (TABLE). Conclusions: Over the past decade, 1-year survival after IHCA has significantly improved each year.

Abstract Introduction This study is aimed to investigate the association of intraosseous (IO) versus intravenous (IV) route during cardiopulmonary resuscitation (CPR) with outcomes after out-of-hospital cardiac arrest (OHCA). Methods We systematically searched PubMed, Embase, Cochrane Library and Web of Science from the database inception through April 2020. Our search strings included designed keywords for two concepts, i.e. vascular access and cardiac arrest. There were no limitations implemented in the search strategy. We selected studies comparing IO versus IV access in neurological or survival outcomes after OHCA. Favourable neurological outcome at hospital discharge was pre-specified as the primary outcome. We pooled the effect estimates in random-effects models and quantified the heterogeneity by the I2 statistics. Time to intervention, defined as time interval from call for emergency medical services to establishing vascular access or administering medications, was hypothesized to be a potential outcome moderator and examined in subgroup analysis with meta-regression. Results Nine retrospective observational studies involving 111,746 adult OHCA patients were included. Most studies were rated as high quality according to Newcastle-Ottawa Scale. The pooled results demonstrated no significant association between types of vascular access and the primary outcome (odds ratio [OR], 0.60; 95% confidence interval [CI], 0.27–1.33; I2, 95%). In subgroup analysis, time to intervention was noted to be positively associated with the pooled OR of achieving the primary outcome (OR: 3.95, 95% CI, 1.42–11.02, p: 0.02). That is, when the studies not accounting for the variable of “time to intervention” in the statistical analysis were pooled together, the meta-analytic results between IO access and favourable outcomes would be biased toward inverse association. No obvious publication bias was detected by the funnel plot. Conclusions The meta-analysis revealed no significant association between types of vascular access and neurological outcomes at hospital discharge among OHCA patients. Time to intervention was identified to be an important outcome moderator in this meta-analysis of observation studies. These results call for the need for future clinical trials to investigate the unbiased effect of IO use on OHCA CPR.

AbstractIn Taiwan, the outcomes of acute limb ischemia have yet to be investigated in a standardized manner. In this study, we compared the safety, feasibility and outcomes of acute limb ischemia after surgical embolectomy or catheter-directed therapy in Taiwan. This study used data collected from the Taiwan’s National Health Insurance Database (NHID) and Cause of Death Data between the years 2000 and 2015. The rate ratio of all-cause in-hospital mortality and risk of amputation during the same period of hospital stay were estimated using Generalized linear models (GLM). There was no significant difference in mortality risk between CDT and surgical intervention (9.5% vs. 10.68%, adjusted rate ratio (95% CI): regression 1.0 [0.79–1.27], PS matching 0.92 [0.69–1.23]). The risk of amputation was also comparable between the two groups. (13.59% vs. 14.81%, adjusted rate ratio (95% CI): regression 0.84 [0.68–1.02], PS matching 0.92 [0.72–1.17]). Age (p < 0.001) and liver disease (p = 0.01) were associated with higher mortality risks. Heart failure (p = 0.03) and chronic or end-stage renal disease (p = 0.03) were associated with higher amputation risks. Prior antithrombotic agent use (p = 0.03) was associated with a reduced risk of amputation. Both surgical intervention and CDT are effective and feasible procedures for patients with ALI in Taiwan.

Aims/Objectives/BackgroundOut-of-hospital cardiac arrest (OHCA) is prevalent in the UK. Reported survival is lower than in countries with comparable healthcare systems; a better understanding of outcome determinants may identify areas for improvement. Aim: to compare differential determinants of survival to hospital admission and survival to hospital discharge for traumatic (TCA) and non-traumatic cardiac arrest (NCTA).Methods/DesignAn analysis of 9109 OHCA in East of England between 1 January 2015 and 31 July 2017. Univariate descriptives and multivariable analysis were used to understand the determinants of survival for NTCA and TCA. Two Utstein outcome variables were used: survival to hospital admission and hospital discharge. Data reported as number (percentage), number (percentage (95% CI)) and median (IQR) as appropriate. Continuous data have been analysed with a Mann-Whitney U test, and categorical data have been analysed with a χ2 test. Analyses were performed using the R statistical programming language.Results/ConclusionsThe incidence of OHCA was 55.1 per 100 000 population/year. The overall survival to hospital admission was 27.6% (95%CI 26.7% to 28.6%) and the overall survival to discharge was 7.9% (95%CI 7.3% to 8.5%). Survival to hospital admission and survival to hospital discharge were both greater in the NTCA group compared with the TCA group: 27.9% vs 19.3% p=0.001, and 8.0% vs 3.8% p=0.012 respectively.Determinants of NTCA and TCA survival were different, and varied according to the outcome examined. In NTCA, bystander cardiopulmonary resuscitation (CPR) was associated with survival at discharge but not at admission, and the likelihood of bystander-CPR was dependent on geographical socioeconomic status.NTCA and TCA are clinically distinct entities with different predictors for outcome and should be reported separately. Determinants of survival to hospital admission and discharge differ in a way that likely reflects the determinants of neurological injury. Bystander CPR public engagement may be best focused in more deprived areas.

ObjectiveThe purpose of this study was to assess the trends in outcomes of out-of-hospital cardiac arrest (OHCA) in Beijing over 5 years.DesignCross-sectional study.MethodsAdult patients with OHCA of all aetiologies who were treated by the Beijing emergency medical service (EMS) between January 2013 and December 2017 were analysed. Data were collected using the Utstein Style. Cases were followed up for 1 year. Descriptive statistics were used to characterise the sample and logistic regression was performed.ResultsOverall, 5016 patients with OHCA underwent attempted resuscitation by the EMS in urban areas of Beijing during the study period. Survival to hospital discharge was 1.2% in 2013 and 1.6% in 2017 (adjusted rate ratio=1.0, p for trend=0.60). Survival to admission and neurological outcome at discharge did not significantly improve from 2013 to 2017. Patient characteristics and the aetiology and location of cardiac arrest were consistent, but there was a decrease in the initial shockable rhythm (from 6.5% to 5.6%) over the 5 years. The rate of bystander cardiopulmonary resuscitation (CPR) increased steadily over the years (from 10.4% to 19.4%).ConclusionSurvival after OHCA in urban areas of Beijing did not improve significantly over 5 years, with long-term survival being unchanged, although the rate of bystander CPR increased steadily, which enhanced the outcomes of patients who underwent bystander CPR.

Introduction: It is well established that AEDs improve outcome in shockable out-of-hospital cardiac arrest (OHCA). An increasing proportion (now the majority) of OHCAs present with non-shockable rhythms. Survival from non-shockable OHCA depends on high-quality CPR in transit to definitive care. Studies of AED use in non-shockable in-hospital arrest (as opposed to OHCA) have shown reduced survival with AED application possibly due to CPR interruptions to apply pads and perform rhythm analysis. We sought to determine whether AED application in non-shockable public, witnessed OHCA has a significant association with survival to discharge. Methods: This is a retrospective analysis of OHCA from 2010-2015 at 10 Resuscitation Outcomes Consortium centers. All adult, public, witnessed non-shockable OHCAs were included. Non-shockable arrest was defined as no shock delivered by the AED or by review of defibrillator tracings (10%). The initial rhythm on EMS arrival was used to confirm the rhythm. The primary outcome was survival to hospital discharge with favorable neurological status (modified rankin score <3). The OR was adjusted for the Utstein variables. Results: During the study period there were 1,597 non-shockable public, witnessed OHCA, 9.8% of which had an AED applied. The initial rhythm on EMS arrival was PEA or asystole in 86% of cases. Significantly more OHCA in the AED applied group had CPR performed. 6.5% of those without an AED applied survived with favorable neurologic status compared to 9% with an AED. After adjustment for the Utstein variables including bystander CPR, the aOR for survival with favorable neurologic outcome was 1.38 (95% CI:0.72-2.65). Conclusion: After adjusting for patient characteristics and bystander CPR, the application of an AED in non-shockable public witnessed OHCA had no significant association with survival or neurological outcome supporting the relative safety and potential benefit of AED application in non-shockable OHCA.
