Novel classification for adverse events in GI endoscopy: the AGREE classification

Post written by Paul Fockens, MD, PhD, from the Department of Gastroenterology and Hepatology, Research Institute Amsterdam Gastroenterology & Metabolism, Amsterdam University Medical Center, Amsterdam, The Netherlands.


Our research showed that there is no commonly used classification for adverse events in GI endoscopy (AGREE). We developed and tested a new classification based on a universally used surgical classification (Clavien-Dindo).

This new AGREE classification was shown to be simple and reproducible and will hopefully be implemented by many GI endoscopy societies across the world.

Broad implementation of the AGREE classification may facilitate the evaluation of adverse events (AEs) across different endoscopists, disciplines, endoscopy services, and regions. This standardization of AE reporting will support improved quality assurance in GI endoscopy.

The perception of endoscopists, endoscopy nurses, and patients corresponded with the severity grading of the AGREE classification in 80% of cases. Fifty-seven of 84 experts (68%) completed a questionnaire regarding the acceptability of the AGREE classification. The experts consulted considered the AGREE classification simple (86%), reproducible (98%), logical (98%), and useful (96%).
