Self-Directed Virtual Reality-Based Training versus Traditional Physician-Led Teaching for Point-of-Care Cardiac Ultrasound: A Randomized Controlled Study
Authors' conclusion
Our study demonstrates that at 1 month post-training, self-directed VR training was noninferior to PL training.
Study context
- Population
- Medical students with no prior formal ultrasound training, tertiary university hospital in Singapore
- Participants
- 43 medical students
- Comparison
- Virtual-reality (VR) vs physician-led (PL)
Methodological detailssingle blinded (observer), noninferiority, parallel group, single-centre
- Single blinded (observer)
- Noninferiority
- Parallel group
- Single-centre
Primary result
As reported in the abstract
MCQ score change from baseline and practical skills scores · 1 month post-training
- Greater mean change from baseline multiple-choice question (MCQ) scores in PL vs VR, not statistically significant
- p = 0.12
- Higher practical scores in VR vs PL, not statistically significant
- p = 0.06
Further findings
Mean
| Outcome | VR | PL | P value |
|---|---|---|---|
| Baseline MCQ scores | 13.4 | 10.7 | |
| MCQ score improvement from baseline · immediately post-trainingGreater improvement in PL | P = 0.03 | ||
| Total practical scores · immediately post-trainingHigher in PL | P < 0.01 |
