Background: Cognition, part of surgical competence, employs forward planning, error prevention, and orchestration of technical skills. Thus, an understanding of mental processes used by experts throughout patient care is essential to teaching such competencies. The authors' study aimed to analyze and compare mental models of two distinct procedures in plastic surgery-breast augmentation and flexor tendon repair-to develop a framework to define cognitive competencies in plastic surgery aided by a review of the literature.

Background: Efforts to improve surgical safety and outcomes have traditionally placed little emphasis on intraoperative performance, partly due to difficulties in measurement. Video-based assessment (VBA) provides an opportunity for blinded and unbiased appraisal of surgeon performance. Therefore, we aimed to systematically review the existing literature on the association between intraoperative technical performance, measured using VBA, and patient outcomes.
