Validation of the AUA BLUS Tasks

Purpose: Standardized assessment of laparoscopic skill in urology is lacking. We investigated whether the AUA (American Urological Association) BLUS (Basic Laparoscopic Urologic Skills) skill tasks are valid to address this need.Materials and Methods: This institutional review board approved study included 27 medical students, 42 urology residents, 18 fellows and 37 faculty urologists across 8 sites. Using the EDGE (Electronic Data Generation and Evaluation) device (Simulab, Seattle, Washington) 454 recordings were collected on peg transfer, pattern cutting, suturing and clip applying tasks, which together comprise the expert determined BLUS tasks. We collected synchronized video and tool motion data for each trial. For each task errors, time, path length, economy of motion, peak grasp force and EDGE score were collected. An expert panel of 5 faculty members performed GOALS (Global Objective Assessment of Laparoscopic Skills) evaluations on a representative subset of peg transfer and suturing skill tasks ...
