Title
Training in Soft-Tissue Resection Using Real-Time Visual Computer Navigation Feedback from Surgery Tutor: A Randomized Controlled Trial
Length of Presentation
Background/Purpose
In competency-based medical education (CBME), surgery trainees are often required to learn procedural skills in a simulated setting before proceeding to the clinical environment. The Surgery Tutor computer navigation platform allows for real-time proctorless assessment of open soft-tissue resection skills; however, the use of this platform as an aid in acquisition of procedural skills is yet to be explored.
Methods
In this prospective randomized controlled trial, 20 final year medical students were randomized to receive either real-time computer navigation feedback (Intervention, n=10) or conventional simulation training (Control, n=10) during simulated non-palpable soft-tissue tumor resections. Real-time computer navigation allowed participants to see the position of their scalpel relative to the tumor. Each participant performed 7 resections. The Surgery Tutor platform collected assessment metrics for each resection.
Results
Training with real-time computer navigation feedback resulted in a 0% positive margin rate as compared to 30% with conventional simulation training (p = 0.06). Participants in the Intervention group also performed resections with less excised tissue [12.1(10.5-15.4) vs. 20.3(15.6-22.9) g; p = 0.005], shorter distance moved by the scalpel [8.95(7.84-11.0) vs. 11.6(10.3-12.4) m; p=0.02] and fewer scalpel motions [163(139-212) vs. 226(213-254); p=0.01] as compared to the Control group. After removal of computer navigation feedback, the Intervention group maintained a 0% positive margin rate indicating retention of learned skills.
Conclusion
Real-time visual computer navigation feedback from Surgery Tutor resulted in superior acquisition and retention of procedural skills as compared to conventional simulation training.
