Abstract

BackgroundAlthough simulation training and evaluation have become increasingly popular for teaching minimally invasive surgery, tools to measure open surgical skills remain underdeveloped. As there is increasing demand for objective measures of technical competency at the completion of surgical training (postgraduate year [PGY]-6 and -7), this project was designed to assess the feasibility, reliability, and validity of a novel open surgical skills evaluation tool, the 8-min suture test (8MST).MethodsDuring an annual surgical skills laboratory session, fellows and residents were asked to complete a simulated end-to-end vascular anastomosis. They were limited to 8 min to perform the anastomosis between two 12-mm Dacron grafts mounted on a customized platform. Their real-time and video-recorded performance was scored by two blinded evaluators and compared with their faculty-rated technical performance on clinical rotations completed around the time of 8MST administration.ResultsPGY-6 and PGY-7 trainees were compared across several domains including 8MST total score (4.6 versus 5.5, P = 0.030), 8MST setup score (2.3 versus 2.4, P = 0.797), 8MST technical score (2.3 versus 3.1, P = 0.026), and clinical performance score (3.1 versus 3.6, P = 0.006). Comparison of 8MST total score to the clinical performance score identified a strong relationship with a Pearson r = 0.55 (P < 0.001) and r2 = 0.30. Additionally, 8MST displayed high inter-rater reliability and test–retest reliability.ConclusionsThe 8MST is a rapid, feasible, inexpensive, reliable, and valid test for assessment of surgical trainee technical abilities.
