Why the study?
Does the C-PASS algorithm provide an objective, reproducible, and accurate assessment of surgical and endoscopic skills?
Does the C-PASS algorithm provide an objective, reproducible, and accurate assessment of surgical and endoscopic skills?
C-PASS provides an objective, reproducible, and accurate method for assessing surgical and endoscopic skills, which may improve skills acquisition and enable objective comparison of techniques.
May support objective surgical skills assessment; leaves open adoption in training pending prospective validation.
Historically, the performance of surgeons has been assessed subjectively by senior surgical staff in both training and operating environments. In this work, the position and motion of surgical instruments are analyzed through an objective process, denoted C-PASS, to measure surgeon performance of laparoscopic, endoscopic, and image-guided procedures. To develop C-PASS, clinically relevant performance characteristics were identified. Then measurement techniques for parameters that represented each characteristic were derived, and analytic techniques were implemented to transform these parameters into explicit, robust metrics. The metrics comprise the C-PASS performance assessment method, which has been validated over the last 3 years in studies of laparoscopy and endoscopy. These studies show that C-PASS is straightforward, reproducible, and accurate. It is sufficiently powerful to assess the efficiency of these complex processes. It is likely that C-PASS and similar approaches will improve skills acquisition and learning and also enable the objective comparison of systems and techniques.
