Project description:BackgroundHigh-quality leadership improves resuscitation for in-hospital cardiac arrest (IHCA), but experienced resuscitation leaders are unavailable in many settings.Research questionDoes real-time telemedical intensivist consultation improve resuscitation quality for IHCA?Study design and methodsIn this multicenter randomized controlled trial, standardized high-fidelity simulations of IHCA conducted between February 2017 and September 2018 on inpatient medicine and surgery units at seven hospitals were assigned randomly to consultation (intervention) or simulated observation (control) by a critical care physician via telemedicine. The primary outcome was the fraction of time without chest compressions (ie, no-flow fraction) during an approximately 4- to 6-min analysis window beginning with telemedicine activation. Secondary outcomes included other measures of chest compression quality, defibrillation and medication timing, resuscitation protocol adherence, nontechnical team performance, and participants' experience during resuscitation participation.ResultsNo-flow fraction did not differ between the 36 intervention group (0.22 ± 0.13) and the 35 control group (0.19 ± 0.10) resuscitation simulations included in the intention-to-treat analysis (P = .41). The etiology of the simulated cardiac arrest was identified more often during evaluable resuscitations supported by a telemedical intensivist consultant (22/32 [69%]) compared with control resuscitations (10/34 [29%]; P = .001), but other measures of resuscitation quality, resuscitation team performance, and participant experience did not differ between intervention groups. Problems with audio quality or the telemedicine connection affected 14 intervention group resuscitations (39%).InterpretationConsultation by a telemedical intensivist physician did not improve resuscitation quality during simulated ward-based IHCA.Trial registryClinicalTrials.gov; No.: NCT03000829; URL: www.Clinicaltrialsgov.

Project description:Cardiac arrest is a leading cause of death in developed countries. Although a majority of cardiac arrest patients die during the acute event, a substantial proportion of cardiac arrest deaths occur in patients following successful resuscitation and can be attributed to the development of post-cardiac arrest syndrome. There is growing recognition that integrated post-resuscitation care, which encompasses targeted temperature management (TTM), early coronary angiography and comprehensive critical care, can improve patient outcomes. TTM has been shown to improve survival and neurological outcome in patients who remain comatose especially following out-of-hospital cardiac arrest due to ventricular arrhythmias. Early coronary angiography and revascularisation if needed may also be beneficial during the post-resuscitation phase, based on data from observational studies. In addition, resuscitated patients usually require intensive care, which includes mechanical ventilator, haemodynamic support and close monitoring of blood gases, glucose, electrolytes, seizures and other disease-specific intervention. Efforts should be taken to avoid premature withdrawal of life-supporting treatment, especially in patients treated with TTM. Given that resources and personnel needed to provide high-quality post-resuscitation care may not exist at all hospitals, professional societies have recommended regionalisation of post-resuscitation care in specialised 'cardiac arrest centres' as a strategy to improve cardiac arrest outcomes. Finally, evidence for post-resuscitation care following in-hospital cardiac arrest is largely extrapolated from studies in patients with out-of-hospital cardiac arrest. Future studies need to examine the effectiveness of different post-resuscitation strategies, such as TTM, in patients with in-hospital cardiac arrest.

Project description:Background Although many hospitals have resuscitation champions, it is unknown if hospitals with very active physician or nonphysician champions have higher survival rates for in-hospital cardiac arrest (IHCA). Methods and Results We surveyed adult hospitals in Get With The Guidelines-Resuscitation about resuscitation practices, including about their resuscitation champion. Hospitals were categorized as having a very active physician champion, a very active nonphysician champion, or other (no champion or not very active champion). For each hospital, we calculated risk-standardized survival rates for IHCA during the period of 2016 to 2018 and categorized them into quintiles of risk-standardized survival rates. The association between a hospital's resuscitation champion type and their quintile of survival was evaluated using multivariable hierarchical proportional odds logistic regression. Overall, 192 hospitals (total of 44 477 IHCAs) comprised the study cohort. Risk-standardized survival rates for IHCA varied widely between hospitals (median: 24.7%; range: 9.2%-37.5%). Very active physician champions were present in 29 (15.1%) hospitals, 64 (33.3%) had very active nonphysician champions, and 99 (51.6%) did not have a very active champion. Compared with sites without a very active resuscitation champion, hospitals with a very active physician champion were 4 times more likely to be in a higher survival quintile, even after adjusting for resuscitation practices across hospital groups (adjusted odds ratio [OR], 3.90; 95% CI, 1.39-10.95). In contrast, there was no difference in survival between sites without very active champions and those with very active non-physician champions (adjusted OR, 1.28; 95% CI, 0.62-2.65). Conclusions The background and engagement level of a resuscitation champion is a critical factor in a hospital's survival outcomes for IHCA.

Project description:ObjectivesTo assess trainees' performance in managing a patient with post-cardiac arrest complicated by status epilepticus.MethodsIn this prospective, observational, single-center simulation-based study, trainees ranging from sub interns to critical care fellows evaluated and managed a post cardiac arrest patient, complicated by status epilepticus. Critical action items were developed by a modified Delphi approach based on American Heart Association guidelines and the Neurocritical Care Society's Emergency Neurological Life Support protocols. The primary outcome measure was the critical action item sum score. We sought validity evidence to support our findings by including attending neurocritical care physicians and comparing performance across four levels of training.ResultsForty-nine participants completed the simulation. The mean sum of critical actions completed by trainees was 10/21 (49%). Eleven (22%) trainees verbalized a differential diagnosis for the arrest. Thirty-two (65%) reviewed the electrocardiogram, recognized it as abnormal, and consulted cardiology. Forty trainees (81%) independently decided to start temperature management, but only 20 (41%) insisted on it when asked to reconsider. There was an effect of level of training on critical action checklist sum scores (novice mean score [standard deviation (SD)] = 4.8(1.8) vs. intermediate mean score (SD) = 10.4(2.1) vs. advanced mean score (D) = 11.6(3.0) vs. expert mean score (SD) = 14.7(2.2)).ConclusionsHigh-fidelity manikin-based simulation holds promise as an assessment tool in the performance of post-cardiac arrest care.

Project description:BackgroundIn the setting of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, data from autopsy in subjects who died at home during lockdown are scarce. We here report the first forensic autopsy series of coronavirus disease 2019 (COVID-19)-related out-of-hospital cardiac arrest (OHCA).MethodsBetween March and April 2020, four COVID-19-related OHCA were autopsied at the Institute of Legal Medicine of the metropolitan area of Lyon (France) according safe recommended procedures.ResultsFour Caucasian individuals (3 men/1 woman; age: 56.8±2.1 years, body mass index: 29.5±7.4 kg/m2), presenting symptomatic COVID-19 were autopsied. Autopsies of 3 individuals reported natural death by acute respiratory failure implicating SARS-CoV-2 with typical COVID-19 pulmonary aspect of gross findings and pulmonary microscopy findings, i.e., diffusely congestive edematous lungs with peripheral thrombi and diffuse alveolar damage (DAD) at different stages of inflammatory reaction. For one individual, autopsy concluded of violent death due to suicidal acute alcohol intoxication in a patient that could no longer endure COVID-19 lockdown. No significant lesions were found in the heart.ConclusionsWe report here OHCAs of non-cardiac cause directly implicating COVID-19 at various stages of SARS-CoV-2-related DAD. Thus, autopsy remain of interest during this epidemic, both legally and medically to better understand the pathogenic processes of this emerging infectious disease.

Project description:BackgroundSome patients with out-of-hospital cardiac arrest (OHCA) assessed by emergency medical services (EMS) do not receive attempts at resuscitation on the basis of perceived futility.Aims1) To measure variability in the initiation of resuscitation attempts in EMS-assessed OHCA patients across EMS agencies, 2) to evaluate the association between selected EMS agency characteristics and the proportion of patients receiving resuscitation attempts, and 3) to evaluate the association between proportion receiving resuscitation attempts and survival.MethodsA retrospective cohort study using data from 129 EMS agencies participating in the Resuscitation Outcomes Consortium (ROC) epidemiologic registry (EPISTRY) - Cardiac Arrest from 12/01/2005 to 12/31/2010. We included non-traumatic OHCA patients assessed by EMS.ResultsWe included 86,912 OHCA patients. Overall, 54.8% had resuscitation attempted by EMS providers, varying from 23.9% to 100% (p=<0.001) across EMS agencies. The proportion of patients receiving a resuscitation attempt was 7.87% less (95% CI 3.73-12.0) among agencies with longer average response intervals (≥6min) compared with shorter average response intervals (<6min) and 16.9% less (95% CI 11.9-21.9) among agencies with higher levels of advanced life support (ALS) availability (≥50% of available units) compared with lower levels of ALS availability (<50% of available units). There was a moderate positive correlation between the proportion of patients with resuscitation attempts and survival to hospital discharge (r=0.54, p<0.001).ConclusionsThe proportion of patients with OHCA who receive resuscitation attempts is variable across EMS agencies and is associated with EMS response interval, ALS unit availability and geographic region. On average, survival was higher among EMS agencies more likely to initiate resuscitation.

Project description:IntroductionHyperoxia has recently been reported as an independent risk factor for mortality in patients resuscitated from cardiac arrest. We examined the independent relationship between hyperoxia and outcomes in such patients.MethodsWe divided patients resuscitated from nontraumatic cardiac arrest from 125 intensive care units (ICUs) into three groups according to worst PaO2 level or alveolar-arterial O2 gradient in the first 24 hours after admission. We defined 'hyperoxia' as PaO2 of 300 mmHg or greater, 'hypoxia/poor O2 transfer' as either PaO2 < 60 mmHg or ratio of PaO2 to fraction of inspired oxygen (FiO2 ) < 300, 'normoxia' as any value between hypoxia and hyperoxia and 'isolated hypoxemia' as PaO2 < 60 mmHg regardless of FiO2. Mortality at hospital discharge was the main outcome measure.ResultsOf 12,108 total patients, 1,285 (10.6%) had hyperoxia, 8,904 (73.5%) had hypoxia/poor O2 transfer, 1,919 (15.9%) had normoxia and 1,168 (9.7%) had isolated hypoxemia (PaO2 < 60 mmHg). The hyperoxia group had higher mortality (754 (59%) of 1,285 patients; 95% confidence interval (95% CI), 56% to 61%) than the normoxia group (911 (47%) of 1,919 patients; 95% CI, 45% to 50%) with a proportional difference of 11% (95% CI, 8% to 15%), but not higher than the hypoxia group (5,303 (60%) of 8,904 patients; 95% CI, 59% to 61%). In a multivariable model controlling for some potential confounders, including illness severity, hyperoxia had an odds ratio for hospital death of 1.2 (95% CI, 1.1 to 1.6). However, once we applied Cox proportional hazards modelling of survival, sensitivity analyses using deciles of hypoxemia, time period matching and hyperoxia defined as PaO2 > 400 mmHg, hyperoxia had no independent association with mortality. Importantly, after adjustment for FiO2 and the relevant covariates, PaO2 was no longer predictive of hospital mortality (P = 0.21).ConclusionsAmong patients admitted to the ICU after cardiac arrest, hyperoxia did not have a robust or consistently reproducible association with mortality. We urge caution in implementing policies of deliberate decreases in FiO2 in these patients.

Project description:IntroductionIn-situ simulation (ISS) is a method to evaluate the performance of hospital units in performing cardiopulmonary resuscitation (CPR). It is conducted by placing a high-fidelity mannequin at hospital units with simulated scenarios and having each unit's performance evaluated. However, little is known about its impact on actual patient outcomes. Therefore, we aimed to evaluate the association between the ISS results and actual outcomes of patients with in-hospital cardiac arrest (IHCA).MethodsThis retrospective study was conducted by reviewing Siriraj Hospital's CPR ISS results in association with the data of IHCA patients between January 2012 and January 2019. Actual outcomes were determined by patients' outcomes (sustained return of spontaneous circulation (ROSC) and survival to hospital discharge) and arrest performance indicators (time-to-first-epinephrine and time-to-defibrillation). These outcomes were investigated for association with the ISS scores in multilevel regression models with hospital units as clusters.ResultsThere were 2146 cardiac arrests included with sustained ROSC rate of 65.3% and survival to hospital discharge rate of 12.9%. Higher ISS scores were significantly associated with improved sustained ROSC rate (adjusted odds ratio 1.32 (95%CI 1.04, 1.67); p = 0.01) and a decrease in time-to-defibrillation (-0.42 (95%CI -0.73, -0.11); p = 0.009). Although higher scores were also associated with better survival to hospital discharge and a decrease in time-to-first-epinephrine, most models for these outcomes failed to reach statistical significance.ConclusionCPR ISS results were associated with some important patient outcomes and arrest performance indicators. Therefore, it may be an appropriate performance evaluation method that can guide the direction of improvement.

Project description:Extracorporeal cardiopulmonary resuscitation (ECPR) followed by targeted temperature management has been demonstrated to significantly improve the outcomes of out-of-hospital cardiac arrest (OHCA) in adult patients. Although recent narrative and systematic reviews on extracorporeal life support in the emergency department are available in the literature, they are focused on the efficacy of ECPR, and no comprehensively summarized review on ECPR for OHCA in adult patients is available. In this review, we aimed to clarify the prevalence, pathophysiology, predictors, management, and details of the complications of ECPR for OHCA, all of which have not been reviewed in previous literature, with the aim of facilitating understanding among acute care physicians. The leading countries in the field of ECPR are those in East Asia followed by those in Europe and the United States. ECPR may reduce the risks of reperfusion injury and deterioration to secondary brain injury. Unlike conventional cardiopulmonary resuscitation, however, no clear prognostic markers have been identified for ECPR for OHCA. Bleeding was identified as the most common complication of ECPR in patients with OHCA. Future studies should combine ECPR with intra-aortic balloon pump, extracorporeal membrane oxygenation flow, target blood pressure, and seizure management in ECPR.
