Core Tip

Core Tip: This study evaluates the real-world impact of varying computer-aided detection (CADe) usage frequency on colonoscopy quality metrics in a tertiary Australian endoscopy center. Endoscopists were stratified by CADe usage, revealing that even partial use (50%-99% of procedures) significantly improved adenoma detection rate (ADR). High-frequency users maintained high ADR, but total adenomas per procedure increased, highlighting additional quality benefits. The findings emphasize that CADe effectiveness depends not only on technology availability but also on endoscopist level of usage, offering insights into optimizing implementation and improving patient outcomes through enhanced polyp detection and risk stratification.
