Abstract
(Occulus from Facebook, Facebook Inc., USA)) or mannequin-based (control) simulation for the same SE scenario. The control group participated in two mannequin-based simulation sessions while the intervention group had a VR session followed by a mannequin-based session. Sessions were one-one with an instructor and held three months apart. Performance was assessed by measuring the time-to-critical actions during the second session. Results Of 42 interns, 22 were in the intervention group and 20 in the control group. There was no statistical difference in time-to-critical actions for VR vs. standard groups; for example, VR times (in seconds) compared to standard times were 18.1 (SD 10.5) and 18.9 (SD 15.8) (p=.90) for oral suction, and 61.6 (SD 24.8) and 62.8 (SD 26.9) (p=.82) for IV lorazepam completion. Conclusion This pilot trial suggests that VR is feasible for clinical simulation. We did not find a significant difference between the two groups in learner performance. Larger studies are needed to corroborate our findings, investigate the best applications of VR in clinical training, and determine if it could lead to more rapid learning at a lower cost.
