Simple clinical predictors may obviate urgent endoscopy in selected patients with nonvariceal upper gastrointestinal tract bleeding

Abstract

Background: The validated Blatchford risk score (BRS) predicts outcomes in patients with nonvariceal upper gastrointestinal tract bleeding, before endoscopy; completion of the Rockall score requires endoscopy. The aims of this study were to predict whether the modified BRS (mBRS) can predict (1) endoscopic high-risk stigmata (HRS) and (2) rebleeding and mortality. Methods: Clinical and demographic characteristics on 1869 patients from 6 Canadian provinces were prospectively entered into the Registry for Upper GI Bleeding and Endoscopy database, recording 30-day rebleeding and mortality. The Rockall score and mBRS (hemoglobin level, hemodynamic instability, and presence of melena, liver disease, or cardiac failure; urea and syncope were not recorded) were calculated. Logistic regression was used to assess the association between an mBRS of 1 or less with HRS and with rebleeding and mortality. Results: The mean (SD) age of the patients was 66 (17) years, with 62% men and a mean of 2.5 comorbidities. Of the 1860 patients with 30-day rebleeding data, 334 (18.0%) rebled; 5.3% died. The mBRS was 0 in 3% and 1 or less in 9.8% of patients; HRS were seen in 31.0% of patients. An mBRS of 1 or less was associated with lower rebleeding (5% vs 19%; P
