Using Virtual Reality to teach ultrasound-guided needling skills for regional anaesthesia: A randomised controlled trial
Authors' conclusion
Novices trained using a hybrid, virtual reality-assisted teaching program showed no superiority to novices trained using a conventional teaching program, but with less burden on teaching resources.

Further findings
Inter-rater reliability of scoring between assessors
- Correlation coefficient, global rating scale
- 0.84 (95%CI 0.68-0.92)
- Correlation coefficient, composite error score checklist
- 0.87 (95%CI 0.73-0.93)
Realism of the virtual reality simulator (Presence Questionnaire)
- Similar to real-life, all components p > 0.79
Task workload (NASA-Task Load Index)
- Not statistically different between groups; average treatment effect (95%CI −3.51-13.54), p = 0.25
- 5.02
Human faculty involvement
- Results achieved in the virtual reality-assisted group with half the human faculty involvement
