Comparison of Self Versus Expert-assisted Feedback for Cricothyroidotomy Training

Abstract

The self-video feedback method may have the potential to provide a low-cost alternative to physician-driven simulation-based training. This study aimed to assess the utility of video feedback by comparing the improvement in procedural performance when trainees received self-video feedback (trainees review their performance alone) and expert-assısted video feedback (trainees review their performance while an emergency physician provides additional feedback). This study was performed at a university simulation center with 89 final-year medical students and used a cricothyroidotomy simulation model. Following the educational presentation and the best practice video, trainees were randomized into two groups (self video-feedback and expert assisted video-feedback). They performed the cricothyroidotomy before and after the feedback, The procedures were recorded and scored. Scoring were made using a pre-defıned checklist. Mann Whitney U test and Wilcoxon test were used to analyze non-normally distributed data. For the analysis of normally distributed data, Student t-test and Paired Samples t-test were used. Results demonstrated significant improvement in cricothyroidotomy performance with both types of video feedback. The improvement was significantly greater in the expert-assisted video feedback group. We think that simulation-based training is effective with self video feedback.
