【Abstract】Upper gastrointestinal bleeding (UGIB) is a common emergency,UGIB encompasses a wide range of minor bleeding that may not require intervention to hemorrhagic shock requiring emergency endoscopy or surgery.The international consensus guidelines recommend use risk scoring systems to early assessment patients with UGIB. Which may be useful to distinguish highrisks patients,who may need clinical intervention and hospitalization,from low risk patients with a lower chance of developing complications,in which management as outpatients can be considered.It is important to optimize care and allocate resources efficiently.This article will review and compare the characteristic of Rockall、GlasgowBlatchford（GBS）、AIMS65 scoring systems,which are widely used to evaluate the prognosis of patients with UGIB.
