Background and Aim Acute variceal bleeding (AVB) is a fatal adverse event of cirrhosis, and endoscopic band ligation (EBL) is the standard treatment for AVB. We developed a novel bedside risk‐scoring model to predict the 6‐week mortality in cirrhotic patients undergoing EBL for AVB. Methods Cox regression analysis was used to assess the relationship of clinical, biological, and endoscopic variables with the 6‐week mortality risk after EBL in a derivation cohort ( n = 1373). The primary outcome was the predictive accuracy of the new model for the 6‐week mortality in the validation cohort. Moreover, we tested the adequacy of the mortality risk‐based stratification and the discriminative performance of our new model in comparison with the Child–Turcotte–Pugh (CTP) and the model for end‐stage liver disease scores in the validation cohort ( n = 200). Results On multivariate Cox regression analysis, five objective variables (use of beta‐blockers, hepatocellular carcinoma, CTP class C, hypovolemic shock at initial presentation, and history of hepatic encephalopathy) were scored to generate a 12‐point risk‐prediction model. The model stratified the 6‐week mortality risk in patients as low (3.5%), intermediate (21.1%), and high (53.4%) ( P < 0.001). Time‐dependent area under the receiver operating characteristic curve for 6‐week mortality showed that this model was a better prognostic indicator than the CTP class alone in the derivation ( P < 0.001) and validation ( P < 0.001) cohorts. Conclusions A simplified scoring model with high potential for generalization refines the prediction of 6‐week mortality in high‐risk cirrhotic patients, thereby aiding the targeting and individualization of treatment strategies for decreasing the mortality rate.
