Objective:
This study aims to assess the effectiveness of training medical students to perform two clinical procedures using unsupervised simulation with remote asynchronous feedback, compared to an intensive workshop with in-person feedback.
Design, Setting, And Participants:
Third-year medical students were recruited and randomized into 2 groups: Thoracentesis or paracentesis. Within each group, participants were further randomized into either unsupervised simulation with remote asynchronous feedback (experimental group; EG) or a 2-hour workshop (control group; CG). The EG underwent two unsupervised 20-minute training sessions and received remote asynchronous feedback. The CG had a 2-hour workshop where they received in-person feedback. After training, students were assessed using the objective structured assessment of technical skills (OSATS) scale. Twenty students in thoracentesis and 23 in paracentesis training completed the 2 training sessions with remote and asynchronous feedback, and 30 students for both thoracentesis and paracentesis groups completed the 2-hour workshop.
Results:
The EG achieved a significantly higher passing rate than the CG on both procedures (thoracentesis 80% vs. 43%, paracentesis 91% vs. 67%, p-value< 0.05).
Conclusion:
The asynchronous educational method allowed EG students to achieve higher performance than CG students. This novel modality allowed students and instructors to train and assess at their own pace.
