RESUMO
Objectives: To assess trainees' performance in managing a patient with post-cardiac arrest complicated by status epilepticus. Methods: In 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. Results: Forty-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)). Conclusions: High-fidelity manikin-based simulation holds promise as an assessment tool in the performance of post-cardiac arrest care.
RESUMO
BACKGROUND AND OBJECTIVES: Multidisciplinary acute stroke teams improve acute ischemic stroke management but may hinder trainees' education, which in turn may contribute to poorer outcomes in community hospitals on graduation. Our goal was to assess graduate neurology trainee performance independently of a multidisciplinary stroke team in the management of acute ischemic stroke, tissue plasminogen activator (tPA)-related hemorrhage, and cerebral herniation syndrome. METHODS: In this prospective, observational, single-center simulation-based study, participants (subinterns 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 Neurologic 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 performance across 4 levels of training. RESULTS: Fifty-three trainees (including 31 graduate neurology trainees) and 5 attending physicians completed the simulation. The mean sum of critical actions completed by graduate neurology trainees was 15 of 22 (68%). Ninety percent of graduate neurology trainees properly administered tPA; 84% immediately stopped tPA infusion after 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 [SD] score 7.2 [2.8] vs level 2 mean [SD] score 12.3 [2.6] vs level 3 mean [SD] score 13.3 [2.2] vs level 4 mean [SD] score 16.3 [2.4], p < 0.001, R 2 = 0.54). DISCUSSION: Graduate 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.
