Determining Transfer Effectiveness of Immersive Virtual Reality Skills Training: A Randomized, Intervention-controlled Trial
Description
In this presentation, Ryan Lohre discusses a randomized controlled trial aimed at evaluating the effectiveness of immersive virtual reality (IVR) skills training for orthopedic surgery, specifically in reverse shoulder arthroplasty. Traditional training methods, relying on textbooks and observational learning from experienced surgeons, often limit the opportunity for trainees to practice and learn from their mistakes. In contrast, IVR technology is proposed as a contemporary solution to enhance training efficiency.
The study involves senior orthopedic residents who are randomly assigned to either a control group, which receives technical video training, or an intervention group using the Precision OS IVR module. The trial evaluates various outcomes, including technical skill acquisition via the Objective Structured Assessment of Technical Skills (OSATS), cognitive performance, and efficiency metrics such as completion time and error rates.
Results indicate that the IVR-trained group outperformed the control group in both overall cumulative OSATS scores and verbal knowledge assessments, demonstrating notable efficiencies in training time. The analysis suggests a transfer effectiveness ratio indicating that every hour spent training on the simulator can significantly reduce equivalent real-world training time. Furthermore, the IVR simulator proves to be cost-effective, offering substantial savings over traditional cadaver-based training setups.
Despite certain limitations, including the lack of longitudinal retention study and potential sampling biases, findings support the potential of IVR training in surgical education. The use of skill transfer ratios is recommended for future evaluations, emphasizing improved learning outcomes and cost efficiency in surgical training regimes.
