[Retrospective Study: Comparison of AIMS65, Rockall and Glasgow Blatchford Scores for Upper Gastrointestinal Bleeding].

Introduction: Upper gastrointestinal bleeding constitutes a primary emergency for emergency services world wide. It has varied etiology and broadther apeutics, so the use of prognostic scalesis necessary to establish the patient's risk. Objectives: . Determine which of the four scales studied has a greater capacity to discriminate between cases of low and high risk for rebleeding, need for blood transfusion and death. Materials and methods: . A retrospective cohort study was carried out using the data base of the Guasmo Sur General Hospital from 2020 to 2022, comparing scores obtained by applying the scales to patients diagnosed with upper gastrointestinal bleeding and the irevolution to know their potential prognosis. Results: . In predicting mortality, the following had better AUC: pre-endoscopic Rockall and AIMS65 with 0.701 and 0.689, respectively; the most useful are Rockall and pre-endoscopic Rockall with sensitivity 95% and NPV 98.3%, with cut-off points of 4 and 3, respectively. In predicting rebleeding, the score with the best AUC was GBS with 0.700, at a cut-off point of 9, it had a sensitivity of 92.3% and a NPV of 95.1%. In predicting the need for transfusion, the one with the best AUC was GBS with 0.766, and a cut-off point of 5, it is the most useful with sensitivity 97.1% and NPV 82.6%. Conclusion: . The most useful scales for the different outcomes measured were Rockall, pre-endoscopic Rockall and GBS.
