Practice on an Augmented Reality/ Haptic Simulator and Library of Virtual Brains Improves Residents’ Ability to Perform a Ventriculostomy
16 neurosurgery residents’ live performance of a ventriculostomy was assessed and the rate of successful cannulation on the first pass was recorded. Six months later, 15 virtual brain cases, including normal, compressed, and shifted ventricles or “brain types”, were uploaded onto the vertebroplasty module of the ImmersiveTouch simulator. During a two-to-three hour practice session on the simulator, the same 16 neurosurgery residents were able to practice performing ventriculostomies on each brain type and made an average of three cannulation attempts on each brain type. One month later, the rate of successful cannulation on the first pass was again assessed on live vertebroplasties. Results showed that the success rate six months prior to the practice session was 12% while the success rate one month after the practice session was 32%, showing a significant improvement. These findings suggest the utilization of augmented reality as a practice modem can be beneficial to patient safety outcomes.
“Resident performance on the simulator was consistent with the ‘‘learning curve’’... intermediate-level residents, who perform the bulk of the live procedures in the hospital, outperformed novices and more experienced residents who are no longer routinely performing the procedure...Simulator practice, especially by novice residents, may accelerate learning and shorten the learning curve for this common procedure and thereby decrease morbidity and complications due to inexpert technique.”
