Individualized Deliberate Practice on a Virtual Reality Simulator
Training on simulated models in a surgical skills laboratory has been shown to improve technical performance in the operating room. Currently described simulation-based curricula consist of trainees practicing the same tasks until expert proficiency is reached. It has yet to be investigated whether individualized deliberate practice, where curricula tasks vary depending on prior levels of technical proficiency, would translate to the operating room.
This randomized controlled trial effectively demonstrates that deliberate practice on a virtual reality simulator results in an improvement in technical skills in a real clinical situation. This enhances the feasibility of implementing simulation-based curricula into residency training programs, and consequently has the potential to improve patient safety.

|Official Title:||Individualized Deliberate Practice on a Virtual Reality Simulator Improves Technical Performance of Surgical Novices in the Operating Room: A Randomized Controlled Trial|
- Technical skills [ Time Frame: 6 months ]Participants' technical skills will be assessed in the operating room as they perform a laparoscopic cholecystectomy under supervision. The procedure will be video-recorded and sent for assessment to a blinded evaluator. Technical skills will be assessed using a previously validated technical skills assessment tool (Objective Structured Assessment of Technical Skill - OSATS)
|Study Start Date:||January 2008|
|Study Completion Date:||January 2011|
|Primary Completion Date:||January 2011 (Final data collection date for primary outcome measure)|
Experimental: Deliberate Practice
Residents in the deliberate practice group received individualized feedback at the end of the initial assessment case. The staff surgeon supervising the case completed 3 previously validated technical skills assessment forms.
|Other: Deliberate Practice|
No Intervention: Conventional Feedback
Residents in the control group received informal feedback as they performed the initial laparoscopic cholecystectomy in the operating room. This was left up to the discretion of the staff surgeon supervising the operation. This corresponds to the routine teaching and feedback practices that occur during conventional surgical residency training
