The Role of Collaborative Observational Practice and Feedback-Discourse to Promote Remote Acquisition of Technical Surgical Skills.

Acquisition of technical skills remotely in a decentralized model requires an efficacious way of providing feedback. The primary objective was to test the efficacy of various forms of feedback on the acquisition of surgical skills by medical students. Forty volunteers were randomized to four experimental groups, differing from the nature of feedback (free text versus structured) and who provided the feedback (expert versus peer learners). They had to perform sutures and upload attempts on a learning management system to receive interactive feedback. The pretest and retention test performances were assessed. All groups significantly improved from pretests to retention tests; however, participants using checklist showed statistically lower improvements than the other groups, which did not differ from each other. Remote learners can acquire surgical skills, and most importantly, peers who provide feedback, are as effective as experts if they use open-ended comments and not checklists.
