Embracing errors in simulation-based training: the effect of error training on retention and transfer of central venous catheter skills.
This study suggests that incorporating error training into curricula may result in better skill retention. Surgical interns were exposed to either a video showing only correct placement of central venous catheters, or one showing both correct placement and errors. Trainees performed similarly on immediate postcourse tests, but the group that included error training performed significantly better one month later.
