Self-Guided Immersive Virtual Reality Versus Mannequin-based Simulators to Teach the Ultrasound-Guided Supra-Inguinal Fascia Iliaca Block

This research project aims to see if using immersive virtual reality (iVR) is as good as using traditional mannequins to teach medical staff how to perform a specific nerve block called an ultrasound-guided supra-inguinal fascia iliaca (SIFI) block. This nerve block is important for managing pain in patients with hip fractures, as it can improve recovery, shorten hospital stays, and reduce healthcare costs. Currently, not enough eligible hip fracture patients receive these beneficial nerve blocks.

The study will recruit 36 staff and trainees from anesthesiology, emergency medicine, and orthopedic surgery at The Ottawa Hospital. Participants will be randomly assigned to one of two groups. One group will learn the SIFI block using a newly developed iVR simulator that uses real human anatomy and allows for practice of needling and injecting. The other group will use traditional mannequin-based simulators.

All participants will receive educational materials and videos before their training. Their skills will be tested before the training, immediately after, and again one month later using a hybrid simulator (a combination of a mannequin and a soft embalmed human cadaver part). The main thing being measured is their skill level using a standardized scoring system. The study also wants to see if the iVR simulator is well-tolerated by users. The overall goal is to improve care for hip fracture patients through better, more accessible training for medical staff.
