About

Coen Klos is a surgical researcher dedicated to advancing the assessment and training of minimally invasive and robotic colorectal procedures. His work centers on developing objective, evidence-based tools to evaluate technical skill, with a focus on improving patient outcomes through rigorous simulation and validation. Klos’s most impactful contributions include pioneering the use of simulation for training advanced colorectal procedures and leading the collection of extrapolative validity evidence for the Anastomosis Objective Structured Assessment of Technical Skill (A-OSATS) in robotic ileocolic anastomosis. This latter work, published in 2024, provides critical evidence that the A-OSATS instrument can reliably distinguish between varying levels of surgical expertise, offering a standardized method for assessing performance of a complex side-to-side bowel anastomosis. With his recent publications already garnering citations, Klos is establishing a strong foundation for competency-based surgical education. His research directly addresses the pressing need for objective, reproducible metrics in robotic surgery training, positioning him as a key contributor to the future of surgical skills assessment.
