ABSTRACT
BACKGROUND:
Assessment of mucosal visualization during esophagogastroduodenoscopy (EGD) can be improved with a standardized scoring system. To address this need, we created the Toronto Upper Gastrointestinal Cleaning Score (TUGCS).METHODS:
We developed the TUGCS using Delphi methodology, whereby an international group of endoscopy experts iteratively rated their agreement with proposed TUGCS items and anchors on a 5-point Likert scale. After each Delphi round, we analyzed responses and refined the TUGCS using an 80â% agreement threshold for consensus. We used the intraclass correlation coefficient (ICC) to assess inter-rater and test-retest reliability. We assessed internal consistency with Cronbach's alpha and item-total and inter-item correlations with Pearson's correlation coefficient. We compared TUGCS ratings with an independent endoscopist's global rating of mucosal visualization using Spearman's ρ.RESULTS:
We achieved consensus with 14 invited participants after three Delphi rounds. Inter-rater reliability was high at 0.79 (95â%CI 0.64-0.88). Test-retest reliability was excellent at 0.83 (95â%CI 0.77-0.87). Cronbach's α was 0.81, item-total correlation range was 0.52-0.70, and inter-item correlation range was 0.38-0.74.âThere was a positive correlation between TUGCS ratings and a global rating of visualization (râ=â0.41, Pâ=â0.002). TUGCS ratings for EGDs with global ratings of excellent were significantly higher than those for EGDs with global ratings of fair (Pâ=â0.01).CONCLUSION:
The TUGCS had strong evidence of validity in the clinical setting. The international group of assessors, broad variety of EGD indications, and minimal assessor training improves the potential for dissemination.
