Description
Jorge Espinoza-Ríos and colleagues published a 2026 validation study of the C-WATCH score, a simplified severity tool for upper digestive tract bleeding, at a public hospital in Lima, Peru. Such bleeding kills up to 14 percent of patients in some settings. In a prospective study of 235 patients, the team compared C-WATCH with the AIMS65, Glasgow-Blatchford, and Rockall scores for predicting death within thirty days, transfusion need, and rebleeding.
Thirty-day mortality was 4.7 percent, with gastric ulcers the commonest cause. For mortality, C-WATCH posted the highest discrimination at 0.83, narrowly ahead of AIMS65 and the post-endoscopy Rockall score, yet pairwise testing found no significant advantage over any rival after correction. Results for transfusion need were similar, and every score performed poorly at predicting rebleeding. The authors conclude the simpler C-WATCH performs comparably in this population, supporting its use where a quick score is valued.
