Multi Institutional Experience with the GreenLight Simulator

The objective of this study was to evaluate the GreenLight Laser Sim TM for resident education in a multi institutional study using a structured curriculum. Materials and Methods: Residents from two tertiary care hospitals participated in this study. The curriculum included four SIM modules and four SIM cases on the GreenLight Laser Sim TM . Participants of various training levels were evaluated by grams of tissue vaporized in allotted time, average sweep speed, blood loss, and average laser-tissue distance throughout the study. Results: 20 residents, PGY1-PGY6, completed 331 trials on the simulator. Increased number of trials on the simulator was associated with a statistically significant increase in vaporization efficiency and reduced laser distance. No significant difference was noted between training level or simulator trial number when examining blood loss. Conclusions: This study demonstrates that use of the GreenLight Laser Sim TM is associated with improved vaporization efficiency. The simulator is a useful tool in resident education and instruction of important safety principles and procedural techniques and can help improve vaporization efficiency.
