Abstract

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.

Resumo

Resumo Introdução: O objetivo primário deste estudo foi comparar o efeito da simulação de alta-fidelidade versus autoestudo baseado em resolução de casos no computador, a aquisição de habilidades sobre hipertermia maligna em residentes de anestesiologia do primeiro ano. Métodos: Após a aprovação do Comitê de Ética institucional, 31 residentes de anestesiologia do primeiro ano foram inscritos neste estudo prospectivo, randômico e encoberto. Os participantes foram randomizados para um ambiente de simulação de alta-fidelidade (SAF) ou um estudo de caso (EC) em computador sobre hipertermia maligna. Após a intervenção, o desempenho de todos os indivíduos foi avaliado através de um ambiente de simulação de alta-fidelidade utilizando uma rubrica de avaliação previamente validada. Além disso, uma pesquisa de satisfação e testes de conhecimento foram aplicados. Por fim, uma entrevista semiestruturada foi realizada para avaliar a autopercepção do processo de raciocínio e da tomada de decisão. Resultados: Vinte e oito residentes do primeiro ano concluíram o estudo com sucesso. Os escores dos residentes na aquisição de habilidades no manejo da hipertermia maligna foram globalmente maiores no Grupo SAF que no Grupo EC, mas a significância foi em quatro dos oito elementos da rubrica de desempenho: reconhecer os sinais e sintomas (p = 0,025), priorizaras ações iniciais do manejo (p = 0,003), reconhecer complicações (p = 0,025) e comunicação (p = 0,025). As médias dos escores nos questionários de conhecimento pré- e pós-teste melhoraram de 74% para 85% no Grupo SAF e diminuíram de 78% para 75% no Grupo EC (p = 0,032). Em relação à análise qualitativa, não houve diferença nos fatores que influenciaram o processo de raciocínio e de tomada de decisão dos alunos com ambas as estratégias de ensino. Conclusão: O treinamento baseado em simulação com um ambiente de alta-fidelidade de hipertermia maligna foi superior ao estudo de caso em computador, melhorou o conhecimento e as habilidades no manejo de crises de hipertermia maligna, com um nível de satisfação muito bom entre os residentes de anestesia.
