Introduction: In patients diagnosed with Upper Digestive Bleeding (UDB), clinical guidelines recommend the administration of empirical medical treatment, according to its etiology. Objective: To develop a diagnostic test to predict the etiology of Upper Gastrointestinal Hemorrhage. Materials and methods: Analytical retrospective cohort study. Clinical records of patients over 18 years of age with HDA who attended the emergency service of the Cayetano Heredia Hospital (HCH) in Lima-Peru between 2019 and 2022 were reviewed. Demographic, laboratory and clinical data were collected; subsequently, predictive variables were identified by logistic regression, and a score was assigned to those that most likely predict HDAV, for the construction of a predictive scale. Results: 197 medical records of patients with UGIB were included, of which 127 patients (64%) had non-variceal bleeding, and 70 (36%), variceal. Logistic regression analysis identified four independent predictive factors: red vomit (OR: 4.192, IC 95%: 1.586-11.082), platelet count (OR: 3.786, IC 95%: 1.324-10.826), history of UGIB (OR: 2.634, IC 95%: 1.017-6.820), signs of chronic liver disease (OR: 11.244, IC 95%: 3.067-35.047).with which a predictive scale was constructed, with a cut-off point >7 and ≤7; which showed a sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative of 58.6%, 90.6%, 77.4%, 79.9%, 6.20, and 0.46 respectively. Conclusion: The predictive scale with a cut-off point >7 is useful for predicting the presence of HDAV in patients who come to the emergency room for UGIB.
