To determine the Rockall Preendoscopic scale has greater predictive capacity for the need for endoscopic therapy than the Glasgow Blatchford scale in patients with non-variceal upper gastrointestinal bleeding. Materials and methods: A retrospective, observational diagnostic test study conducted in the gastroenterology service of the Víctor Lazarte Echegaray Hospital with 92 patients with a diagnosis of non-variceal upper gastrointestinal bleeding. The sensitivity, specificity, PPV, NPV of each scale were calculated and the validity indexes and the positive and negative likelihood ratio were compared. Results: The preendoscopic Rockall scale has a sensitivity of 90%, a specificity of 19%, a positive predictive value of 23% and a negative predictive value of 87.5% The Glasgow scale has a sensitivity of 85%, a specificity of 11%, a value positive predictive of 20.9% and a negative predictive value of 72.7%. When comparing both scales, the Rockall scale had a validity index of 34.8%, a positive likelihood ratio of 1.12 and a negative likelihood ratio of 0.51 while the Glasgow Blatchford scale had a validity index of 27.2%, likelihood ratio positive of 0.97 and negative likelihood value of 1.35. Conclusions: The Rockall Preendoscopic scale has greater predictive capacity for the need for endoscopic therapy in patients with non-variceal upper gastrointestinal bleeding.
