Abstract
CONTEXT: In surgical education, traditional Halstedian training models have served well for over 100 years. However in recent years, competency‐based training has generated increasing interest. In many surgical disciplines, simulationbased training will form an essential part of this new paradigm. The successful integration of these new strategies will require establishment of educational curricula that are validated, reliable and can demonstrate learning not only in the laboratory, but also in transfer to the operating room (OR). This program has been designed to evaluate the effectiveness of a novel simulation‐training program in developing microsurgical skills for a cohort of neurosurgical residents.
METHODS: Using an evidence‐based approach, a microsurgical skills curriculum was devised using an established model. Beginning on inanimate objects and culminating in live vascular anastomosis on an anesthetized rat, three residents developed microsurgical skills including use of the microscope, handling of delicate tissue, hemostasis and microsurgical suturing. Performance assessment is underway, through blinded expert review of video‐recordings of the tasks using validated outcome measures. Upon completion of the program, participants will be evaluated on a live operative task (Carotid Endaterectomy) to determine skill transfer to the OR. Their performance will be compared with three control subjects.
RESULTS: All participants have successfully completed the training program and are now completing the operative task, with interim analysis underway. We hypothesize that a statistically significant improvement in skills will be observed within each resident over the course of the training program and when compared to controls on the operative task.
