Multicenter Study
Global Assessment of Gastrointestinal Endoscopic Skills (GAGES): a valid measurement tool for technical skills in flexible endoscopy.
Simulators may improve the efficiency, safety, and quality of endoscopic training. However, no objective, reliable, and valid tool exists to assess clinical endoscopic skills. Such a tool to measure the outcomes of educational strategies is a necessity. This multicenter, multidisciplinary trial aimed to develop instruments for evaluating basic flexible endoscopic skills and to demonstrate their reliability and validity. ⋯ The GAGES-UE and GAGES-C are easy to administer and consistent and meet high standards of reliability and validity. They can be used to measure the effectiveness of simulator training and to provide specific feedback. The GAGES results can be generalized to North American and European endoscopists and may contribute to the definition of technical proficiency in endoscopy.
