Abstract

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.

Methods: Major databases (Medline, Embase, Cochrane Database, and Web of Science) were systematically searched for studies assessing the association of intraoperative technical performance measured by tools supported by validity evidence with short-term (≤ 30 days) and/or long-term postoperative outcomes. Study quality was assessed using the Newcastle-Ottawa Scale. Results were appraised descriptively as study heterogeneity precluded meta-analysis.

Results: A total of 11 observational studies were identified involving 8 different procedures in foregut/bariatric (n = 4), colorectal (n = 4), urologic (n = 2), and hepatobiliary surgery (n = 1). The number of surgeons assessed ranged from 1 to 34; patient sample size ranged from 47 to 10,242. High risk of bias was present in 5 of 8 studies assessing short-term outcomes and 2 of 6 studies assessing long-term outcomes. Short-term outcomes were reported in 8 studies (i.e., morbidity, mortality, and readmission), while 6 reported long-term outcomes (i.e., cancer outcomes, weight loss, and urinary continence). Better intraoperative performance was associated with fewer postoperative complications (6 of 7 studies), reoperations (3 of 4 studies), and readmissions (1 of 4 studies). Long-term outcomes were less commonly investigated, with mixed results.

Conclusion: Current evidence supports an association between superior intraoperative technical performance measured using surgical videos and improved short-term postoperative outcomes. Intraoperative performance analysis using video-based assessment represents a promising approach to surgical quality-improvement.
