Abstract

Background & Aim: An endoscopic classification of Diverticular Disease DD, called DICA Diverticular Inflammation and Complication Assessment is currently available. It scores severity of the disease as DICA 1, DICA 2 and DICA 3. Our aim was to assess the agreement levels for this classification among an endoscopist community setting. Methods: A total of 66 endoscopists independently scored a set of DD endoscopic videos. The percentages of overall agreement on the DICA score and a free-marginal multirater kappa κ coefficient were reported as statistical measures of the inter-rater agreement. Results: The overall agreement levels were: 70.2% for DICA 1, 70.5% for DICA 2, 81.3% for DICA 3. The free marginal κ was: 0.553 for DICA 1, 0.558 for DICA 2, 0.719 for DICA 3. The agreement levels among the expert group were: 78.8% for DICA 1, 80.2% for DICA 2, 88.5% for DICA 3. The free marginal κ among the expert group were: 0.682 for DICA 1, 0.712 for DICA 2, 0.828 for DICA 3. The agreement of expert raters on the single item of the DICA classification was superior to the agreement of the overall group. Conclusions: The overall inter-rater agreement for DICA score in this study ranges from moderate to good, with a significant improvement in the expert subgroup of raters. Diverticular Inflammation and Complication Assessment is a simple and reproducible endoscopic scoring system.
