Does Simulation-Based Training Improve Procedural Skills of Beginners in Interventional Cardiology?-A Stratified Randomized Study.
OBJECTIVE: To assess whether mentored simulation-based-training can improve the procedural skills of beginners in coronary interventional procedures.
BACKGROUND: Simulation based-catheter training is a valuable tool to practice interventional procedures. Whether this type of training enhances the procedural skills of fellows learning percutaneous coronary interventions has never been studied.
METHODS: Eighteen cardiology fellows were randomized either into the simulation-based training (n = 9) or the control group (n = 9). The simulation group received 7.5 hours of virtual reality (VR) simulation training, whereas the control group attended 4.5 hours of lectures. Each participant had to perform a simple (pre-evaluation) and a more complex (post-evaluation) catheter intervention on a pulsatile coronary flow model in a catheterization laboratory. All procedures were videotaped, analyzed, and rated by 3 expert interventionalists, who were blinded to the randomization. To assess the individual performance level, a "skills score" was determined, comprising 14 performance characteristics (5-level Likert scale, maximum score of 70 points).
RESULTS: The "skills score" increased by 5.8 ± 6.1 points in the VR simulation group and decreased by 6.7 ± 8.4 in the control group (P = 0.003) from the simple stenosis at pre- to the more complex lesion at post-evaluation demonstrating the effectiveness of simulation-based training.
CONCLUSION: This pilot study suggests that curriculum-based mentored VR simulation training improves the performance level of cardiology fellows in coronary interventions. Further investigation to evaluate the effect on clinical outcomes is warranted.
