Dangerous professions, such as aviation or the military, require extensive simulation-based training to limit the potential peril as a person gains experience and learns how to do the job. With advances in technology, simulation-based training is an option to improve skills in even more fields, including surgery. > An international research team leading a randomized controlled trial across 10 countries found that while simulation-based training did not statistically improve initial learning curves regarding surgeon's general proficiency, it did produce an increase of skills in more complex surgeries, with fewer total complications and ureteric injuries in the simulation group. The results were published in the journal European Urology.
