Enhancing cosmetic suturing skill acquisition in surgical residents through spaced learning training: a randomized controlled trial.

Background: Previous research has strongly supported the utility of spaced learning in enhancing memory, but its effectiveness in complex surgical procedures has largely been unexplored. The main objective of this study was to evaluate whether, in comparison to concentrated learning, spaced learning improves the short-term acquisition and long-term retention of cosmetic suturing skills as outcomes of surgical resident training courses.

Methods: This randomized controlled trial was conducted from February 2023 to June 2023.
