Table 6 Secondary outcomes on the students’ experiences with self-perceived learning outcomes and perceived usability of simulation methods. Numbers (%) of participants for each group and difference in percentage points with a two-sided 95% confidence interval (95% CI) between groups
Outcome measures | VR group N = 86 | TP group N = 87 | Absolute diff. in % points (95% CI) | P-value |
|---|---|---|---|---|
| Â | N (%) | N (%) | Mean (SD) | Â |
Number of participants who reported (%): | Â | Â | Â | Â |
 - Enough training from the ISBAR video before practicing | 67 (77.7) | 66 (76.7) | 0.3 (−12.2 to 12.8) | 0.750 |
 - Had enough time to practice | 67 (77) | 66 (76.7) | 0.3 (−12.2 to 12.8) | 0.750 |
 - The practice method was likable | 75 (86.2) | 56 (66.7) | 19.5 (6.9 to 31.6) | 0.003* |
 - Training and practice were good ways to learn the ISBAR approach | 74 (86) | 63 (75.9) | 10.1 (−1.7 to 21.9) | 0.110 |
 - Were confident communicating with the ISBAR approach | 50 (57.5) | 37 (44) | 13.4 (−1.5 to 27.6) | 0.056 |
Perceived usability of the simulation method:  - System Usability Scale (range 0–100, higher better) mean score (standard deviation SD) | Mean 78.6 (SD 14.2) | Mean 76.3 (SD 18.4)** | Mean diff. 2.3 (−1.8 to 6.4) | 0.272 |
