FULL STORY ==========================================================================
A large-scale study has found that simulation-based surgical training
produced an increase of surgeons' skills for more complex surgeries.


========================================================================== Practice makes perfect, but what if the practice can be life-threatening? 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.

"To date, there have been limited data, mostly from small-scale studies conducted with medical students, assessing the transferability of surgical simulation," said one of the paper's authors, Takashige Abe, Associate Professor of Urology at Hokkaido University's Graduate School of Medicine
in Japan. "The aim of this multicenter international randomized controlled trial was to evaluate whether surgical residents who undergo additional simulation training are able to achieve proficiency sooner and with better patient outcomes when compared to standard operation room-based training."
The trial followed 65 participants in 10 countries for 18 months, or to a completion of 25 procedures. Split relatively evenly by location, a total
of 32 participants received simulation-based training and 33 received conventional apprenticeship-style training. Both remained supervised by
more experienced surgeons. Altogether, the participants performed a total
of 1,140 surgeries, either semi-rigid or flexible ureteroscopy to remove ureteral or renal stones, respectively, demonstrating "mixed results"
in proficiency.

"For our primary outcome measure, while we showed what might be deemed a clinically meaningful difference, it was not statistically significant,"
Abe said. "However, when stratified to each procedure type, there were
higher rates of proficiency in the simulation-based training group
when it came to the more technically challenging flexible ureteroscopy procedure." Abe also noted that those who underwent simulation-based
training outperformed the other group, scoring higher on a standard
assessment for each surgery.

"Simulation-based training led to higher overall proficiency scores
than for conventional training, and fewer procedures were required to
achieve proficiency in the complex form of the index procedure, with
fewer serious complications overall," Abe said. "It is expected that
the results of the trial will have a positive impact for advanced
procedural training beyond the fields of surgery and urology in
order to promote patients' safety as well as better surgical outcomes." ========================================================================== Story Source: Materials provided by Hokkaido_University. Note: Content
