A randomised control trial study on the efficacy of high-fidelity simulation in enhancing knowledge

Abstract

Introduction: The practice of high-fidelity simulation-based medical education has become a popular small-group teaching modality across all spheres of clinical medicine. High-fidelity simulation (HFS) is now being increasingly used in the context of undergraduate medical education, but its superiority over traditional teaching methods is still not established. The main objective of this study was to analyse the effectiveness of HFS-based teaching over video-assisted lecture (VAL)-based teaching in the enhancement of knowledge for the management of tension pneumothorax among undergraduate medical students. Methods: A cohort of 111 final-year undergraduate medical students were randomised for this study. The efficacy of HFS-based teaching (intervention group) and VAL-based teaching (control group), on the acquisition of knowledge, was assessed by single-best answer multiple choice questions (MCQ) tests in the first and eighth week of their surgery posting. Mean and standard deviation (SD) for the total score of MCQ assessments were used as outcome measures. ANCOVA was used to determine the difference in post-test MCQ marks between groups. The intragroup comparison of the pre-test and post-test MCQ scores was done by using paired t-test. The P-value was set at 0.05. Results: The mean of post-test MCQ scores were significantly higher than the mean of pre-test MCQ scores in both groups. The mean pre-test and post-test MCQ scores in the intervention group were slightly more than those of the control group but not statistically significant. Conclusion: There was a statistically significant enhancement of knowledge in both groups but the difference in knowledge enhancement between the groups was insignificant.
