Comparative Study on Rockall and Blatchford Scoring System for Risk Assessment of Acute Nonvariceal Upper Gastrointestinal Bleeding / 胃肠病学

ABSTRACT

Acute nonvariceal upper gastrointestinal bleeding (ANVUGIB)is a commonly seen gastrointestinal emergency.Rockall and Blatchford scoring system are commonly used for risk stratification in ANVUGIB.Aims:To investigate the predictive values of Rockall and Blatchford scoring system for assessing the risk of blood transfusion,surgical intervention and mortality in patients with ANVUGIB.Methods:Five hundred and ninety hospitalized patients with ANVUGIB were scored by Rockall and Blatchford scoring system,respectively.Predictive values of these two scoring systems for assessing the risk of blood transfusion,surgical intervention and mortality were assessed by area under the receiver operating characteristic (ROC)curve (AUC).Results:Rockall and Blatchford scores in patients with blood transfusion,surgical intervention and died were significantly higher than those in patients without blood transfusion,surgical intervention and survived (P <0.01 ).The AUC of Rockall scoring system for predicting blood transfusion,surgical intervention and mortality were 0.785 (95% CI0.743-0.828,P=0.000),0.765 (95% CI0.693-0.837,P=0.000),0.835 (95% CI0.703-0.966,P=0.005),respectively.The AUC of Blatchford scoring system for predicting blood transfusion,surgical intervention and mortality were 0.812 (95%CI0.775-0.848,P=0.000),0.870 (95%CI0.811-0.930,P=0.000),0.784 (95% CI0.614-0.954,P=0.017),respectively.Conclusions:Rockall and Blatchford scoring system have high predictive value for blood transfusion,surgical intervention and mortality in patients with ANVUGIB.Rockall scoring system is better for predicting mortality,while Blatchford scoring system is better for predicting blood transfusion and surgical intervention.
