Abstract	Introduction: prognostic scales have a wide use in the diagnosis, treatment and monitoring patients with non-variceal upper gastrointestinal bleeding. Objective: determine the predictive ability of clinical component elements of Blatchford modified scale to identify patients most likely to have stigmata of active or recent bleeding during emergency endoscopy. Methods: observational, analytical and prospective study. All patients were included, 188, assisted in the emergency unit at "Dr. Luis Díaz Soto" Central Military Hospital, from January 1 to December 31, 2012. An estimate risk for each scale components was performed. The predictive value using ROC curve was calculated. The sensitivity and specificity of cut off 1 was determined. Results: 61 (32.4 %) out of the patients studied had scars of active or recent bleeding. Stigmas are more likely found in cases with systolic blood pressure ≤ 90 mmHg (RR 7.53; 95 % CI 2.31 to 24.48; p= 0.001), heart rate ≥ 100 beats min (RR 5.49; 95 % CI 2.78 to 10.83; p= 0.001) and hemoglobin ≤ 10 g/dL (RR 4.39; 95% CI 2.17 to 8.89; p = 0.001). The predictive capacity of Blatchford scale was good (c= 0.729; 95 % CI: 0.652 to 0.807; p= .001). The cut point 1 showed a sensitivity of 11.81 % and a specificity of 98.36 %. Conclusions: the value of the Blatchford scale is confirmed abbreviated to predict the presence of stigmata of active or recent bleeding during endoscopic study in patients with non-variceal upper gastrointestinal bleeding.
