Acquiring skills in malignant hyperthermia crisis management: comparison of high‐fidelity simulation versus computer‐based case study

Abstract

Introduction: The primary purpose of this study was to compare the effect of high fidelity simulation versus a computer‐based case solving self‐study, in skills acquisition about malignant hyperthermia on first year anesthesiology residents. Methods: After institutional ethical committee approval, 31 first year anesthesiology residents were enrolled in this prospective randomized single‐blinded study. Participants were randomized to either a High Fidelity Simulation Scenario or a computer‐based Case Study about malignant hyperthermia. After the intervention, all subjects’ performance in was assessed through a high fidelity simulation scenario using a previously validated assessment rubric. Additionally, knowledge tests and a satisfaction survey were applied. Finally, a semi‐structured interview was done to assess self‐perception of reasoning process and decision‐making. Results: 28 first year residents finished successfully the study. Resident's management skill scores were globally higher in High Fidelity Simulation versus Case Study, however they were significant in 4 of the 8 performance rubric elements: recognize signs and symptoms (p = 0.025), prioritization of initial actions of management (p = 0.003), recognize complications (p = 0.025) and communication (p = 0.025). Average scores from pre‐ and post‐test knowledge questionnaires improved from 74% to 85% in the High Fidelity Simulation group, and decreased from 78% to 75% in the Case Study group (p = 0.032). Regarding the qualitative analysis, there was no difference in factors influencing the student's process of reasoning and decision‐making with both teaching strategies. Conclusion: Simulation‐based training with a malignant hyperthermia high‐fidelity scenario was superior to computer‐based case study, improving knowledge and skills in malignant hyperthermia crisis management, with a very good satisfaction level in anesthesia residents.
