title: Blatchford scoring system is a useful scoring system for detecting patients with upper gastrointestinal bleeding who do not need endoscopic intervention.
abstract: OBJECTIVE
  Several scoring systems have been devised to identify patients with upper gastrointestinal (UGI) bleeding who are at a high risk of adverse outcomes. We retrospectively evaluated the accuracy of the Blatchford scoring system for assessing the need for clinical intervention in cases of UGI bleeding admitted to the emergency department (ED).
  
  
  METHODS
  This was a retrospective study conducted on patients who underwent emergency GI endoscopy at the ED of our hospital. Those who needed blood transfusion, operative or endoscopic interventions to control the hemorrhage were classified into the 'high risk' group.
  
  
  RESULTS
  Of the 93 enrolled patients, 70 (75.3%) were classified into the high risk group. The Blatchford score was significantly higher in the high risk group than in the low risk group. When a cut-off value of 2 was used, the sensitivity and specificity of the Blatchford scoring system were determined to be 100% and 13%, respectively. Thus, the Blatchford scoring system was deemed to be useful for distinguishing between the high risk group and the low risk group of patients with GI hemorrhage admitted to the ED.
  
  
  CONCLUSIONS
  The Blatchford scoring system is accurate for identifying definitively low-risk patients of GI hemorrhage, even prior to the performance of emergency UGI endoscopy at the ED.
