Patient safety, competency, and the future of surgical simulation.

Despite its relatively short track record, simulation has been successfully introduced into the surgical arena in an effort to augment training. Initially a fringe endeavor at isolated centers, simulation has now become a mainstream component of surgical education. The surgical community is now aware that the old adage, "see one, do one, and teach one" is no longer acceptable from the ethical standpoint of practicing procedures on patients. Moreover, financial and time constraints have made teaching outside of the operating room an attractive proposition. Coupled with the growing body of validation, new procedures can now be practiced and proficiency can be acquired on a multitude of simulation platforms. Importantly, simulation standards are being established and there is an unprecedented national acceptance and endorsement of simulation as an invaluable educational tool; in fact, simulation is being mandated for surgical residency programs. Team training will likely expand the impact of surgical simulation considerably and help assure multidimensional competency verification. For both surgery residents and surgeons in practice, simulation holds great promise as a safe, effective, and efficient means of acquiring new skills.
