Up to 22% of patients survive to hospital admission following out-of-hospital cardiac arrest (OHCA). Post cardiac arrest is complex and requires a multidisciplinary approach. Our aim is to assess trainee’s performance in managing post-cardiac arrest care using a high-fidelity manikin-based simulation. We also sought to obtain evidence regarding the validity of our findings. Methods: In this prospective, observational, simulation based study, participants ranging from sub interns to attending physicians evaluated and managed a post cardiac arrest patient, complicated by refractory status epilepticus. Critical actions were developed by a modified Delphi approach based on relevant 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 comparing trainees’ performance across four levels of training. Results: Forty-nine participants completed the simulation. The mean sum of critical actions completed by participants was 10/21(49%). Eleven(22%) participants verbalized a differential diagnosis for the arrest. Thirty-two(65%) recognized the abnormal electrocardiography, and consulted cardiology. Forty trainees(81%) independently decided to start target temperature management (TTM), but only 20(41%) insisted on TTM 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 (SD) = 11.6 (3.0) vs. expert mean score (SD) = 14.7 (2.2) Conclusions: High-fidelity manikin-based simulation holds promise as an assessment tool in the performance of post-cardiac arrest care. Areas for further educational initiatives to improve performance include diagnostic work-up of OHCA and implementation of TTM.

Purpose: Target temperature management (TTM) and extracorporeal cardiopulmonary resuscitation (ECPR) have been established as important interventions during cardiopulmonary arrest. However, the impact of combined TTM and ECPR on clinical outcomes has not been studied in detail. Methods: We reviewed the records of 245 patients who received extracorporeal life support (ECLS) between January 2012 and June 2015. Exclusion criteria were as follows: Extracorporeal life support performed for reasons other than cardiac arrest, age less than 18 years, and death within 24 hours. A total of 101 patients were finally included in the study. Twenty-five patients underwent TTM, and 76 patients did not. Results: The patients’ mean age was 55 ± 16.7 years. The mean cardiac arrest time was 44.6 ± 33.5 minutes. There were 84 patients whose cardiac arrest was due to a cardiac cause (83.2%) and 79 patients with in-hospital cardiac arrest (78.2%). There was a significant difference in average body temperature during the first 24 hours following ECPR (33.4°C vs 35.6°C; P = .001). The overall favorable neurological outcome rate was 34% and hospital survival rate was 47%. There was no difference in favorable neurological outcomes and hospital survival between the TTM and non-TTM groups ( P = .91 and .84, respectively). On multivariate analysis of neurological outcomes and hospital survival, TTM was not a significant prognostic factor. Conclusion: We did not observe any benefits of TTM in patients undergoing ECPR. Natural hypothermia or normothermia related to ECLS may explain this result. Further research is needed to understand the role of TTM in ECPR.

Abstract Background Little is known about the effectiveness of surface cooling (SC) and endovascular cooling (EC) on the outcome of out-of-hospital cardiac arrest (OHCA) patients receiving target temperature management (TTM) according to their initial rhythm. Methods We retrospectively analysed data from the Japanese Association for Acute Medicine Out‐of‐Hospital Cardiac Arrest registry, a multicentre, prospective nationwide database in Japan. For our analysis, OHCA patients aged ≥ 18 years who were treated with TTM between June 2014 and December 2017 were included. The primary outcome was 30-day survival with favourable neurological outcome defined as a Glasgow–Pittsburgh cerebral performance category score of 1 or 2. Cooling methods were divided into the following groups: SC (ice packs, fans, air blankets, and surface gel pads) and EC (endovascular catheters and any dialysis technique). We investigated the efficacy of the two categories of cooling methods in two different patient groups divided according to their initially documented rhythm at the scene (shockable or non-shockable) using multivariable logistic regression analysis and propensity score analysis with inverse probability weighting (IPW). Results In the final analysis, 1082 patients were included. Of these, 513 (47.4%) had an initial shockable rhythm and 569 (52.6%) had an initial non-shockable rhythm. The proportion of patients with favourable neurological outcomes in SC and EC was 59.9% vs. 58.3% (264/441 vs. 42/72), and 11.8% (58/490) vs. 21.5% (17/79) in the initial shockable patients and the initial non-shockable patients, respectively. In the multivariable logistic regression analysis, differences between the two cooling methods were not observed among the initial shockable patients (adjusted odd ratio [AOR] 1.51, 95% CI 0.76–3.03), while EC was associated with better neurological outcome among the initial non-shockable patients (AOR 2.21, 95% CI 1.19–4.11). This association was constant in propensity score analysis with IPW (OR 1.40, 95% CI 0.83–2.36; OR 1.87, 95% CI 1.01–3.47 among the initial shockable and non-shockable patients, respectively). Conclusion We suggested that the use of EC was associated with better neurological outcomes in OHCA patients with initial non-shockable rhythm, but not in those with initial shockable rhythm. A TTM implementation strategy based on initial rhythm may be important.

Background and ObjectivesMultidisciplinary acute stroke teams improve acute ischemic stroke management but may hinder trainees’ education which in turn may contribute to poorer outcomes in community hospitals upon graduation. Our goal was to assess graduate neurology trainee performance independent of a multi-disciplinary stroke team in the management of acute ischemic stroke, tissue plasminogen activator (tPA)-related hemorrhage, and cerebral herniation syndrome.MethodsIn this prospective, observational, single-center simulation-based study, participants (sub-interns to attending physicians) managed a patient with acute ischemic stroke followed by tPA-related hemorrhagic conversion leading to cerebral herniation. Critical actions were developed by a modified Delphi approach based on relevant American Heart Association guidelines and the Neurocritical Care Society’s Emergency Neurological Life Support protocols. The primary outcome measure was graduate neurology trainees’ critical action item sum score. We sought validity evidence to support our findings by comparing trainees’ performance across four levels of training.ResultsFifty-three trainees (including 31 graduate neurology trainees) and five attending physicians completed the simulation. The mean sum of critical actions completed by graduate neurology trainees was 15/22 (68%). Ninety percent of graduate neurology trainees properly administered tPA, 84% immediately stopped tPA infusion following patient deterioration, but only 55% reversed tPA according to guidelines. There was a moderately strong effect of level of training on critical action sum score (level 1 mean score [standard deviation (SD)] = 7.2 (2.8) vs. level 2 mean score (SD) = 12.3 (2.6) vs. level 3 mean score (SD) = 13.3 (2.2) vs. level 4 mean score (SD) = 16.3 (2.4), p < .001, R2 = 0.54).DiscussionGraduate neurology trainees reassuringly perform well in initial management of acute ischemic stroke, but frequently make errors in the treatment of hemorrhagic transformation after thrombolysis, suggesting the need for more education surrounding this low frequency, high-acuity event. High-fidelity simulation holds promise as an assessment tool for acute stroke management performance.

Aim: We aimed to investigate the prognostic performance between serum NSE and cerebrospinal fluid (CSF) NSE for 6-month neurologic outcome in OHCA survivors underwent target temperature management (TTM). Hypothesis: We hypothesized that the NSE levels measured in the CSF would affect the change, earlier and more sensitively than serum, according to severity of hypoxic brain damage. Methods: This single-centre prospective observational study included out-of-hospital cardiac arrest (OHCA) patients underwent TTM. NSE levels were assessed in blood and CSF samples obtained immediately (Day 0), and 24 h (Day 1), 48 h (Day 2), and 72 h (Day 3) after return of spontaneous circulation (ROSC). The primary outcome was the 6-month neurological outcome. Results: We enrolled 34 patients (males, 24; 70.6%), 16 (47.1%) had a poor neurologic outcome. CSF NSE and serum NSE values were significantly higher in the poor outcome group compared to the good outcome group at each time point, except for serum Day 0. CSF NSE and serum NSE had area under curve (AUC) of 0.819-0.972 and 0.648-0.920, respectively. CSF NSE prognostic performances were significant higher than serum NSE at Day 1 and showed excellent AUC values (0.969; 95% Confidential Interval [CI] 0.844-0.999) and high sensitivity (93.8%; 95% CI 69.8-99.8) at 100% specificity. Conclusion: We found CSF NSE values were highly predictive and sensitive markers of 6-month poor neurological outcome in OHCA survivors treated with TTM at Day 1 after ROSC. Thus, CSF NSE level at day 1 after ROSC can be a useful early prognosticator in OHCA survivors.

Abstract Background: This study aimed to compare the day-specific association of blood–brain barrier (BBB) disruption with neurological outcomes in out-of-hospital cardiac arrest (OHCA) survivors treated with target temperature management (TTM).Methods: This retrospective single-center study included 68 OHCA survivors, who underwent TTM between April 2018 and December 2019. The albumin quotient (QA) was calculated as [albuminCSF] / [albuminserum] immediately (day 1), and at 24 h (day 2), 48 h (day 3), and 72 h (day 4) after return of spontaneous circulation (ROSC). The degree of BBB disruption was weighted using the following scoring system: 0.07 ≥ QA (normal), 0.01 ≥ QA > 0.007 (mild), 0.02 ≥ QA > 0.01 (moderate), and QA > 0.02 (severe). This system gave it 0 (normal), 1 (mild), 4 (moderate), and 9 (severe) points. Poor neurological outcome was determined at six months after ROSC and was defined as cerebral performance categories 3–5.Results: We enrolled 68 patients (males, 48; 71%); 37 (54%) of them had a poor neurological outcome. The distributions of this outcome at six months in patients with moderate and severe BBB disruption versus the other groups were 19/22 (80%) vs. 18/46 (50%) on day 1, 31/37 (79%) vs. 6/31 (32%) on day 2, 32/37 (81%) vs. 5/31 (30%) on day 3, and 32/39 (85%) vs. 5/29 (30%) on day 4 (P < 0.001). Using ROC analyses, the optimal cutoff values of QA levels for prediction of neurological outcomes were determined as: day 1, > 0.009 (sensitivity 56.8%, specificity 87.1%); day 2, > 0.012 (sensitivity 81.1%, specificity 87.1%); day 3, > 0.013 (sensitivity 83.8%, specificity 87.1%); day 4, > 0.013 (sensitivity 86.5%, specificity 87.1%); sum of all time points, > 0.039 (sensitivity 89.5%, specificity 79.4%); and scoring system, > 9 (sensitivity 91.9%, specificity 87.1%). Conclusions: Our results suggested that QA is a useful tool for predicting neurological outcomes in OHCA survivors treated with TTM. However, the prediction of poor neurological outcome using QA showed low sensitivity at 100% specificity. Thus, it could be used as part of a multimodal approach than as a single prognostic prediction tool.
