OBJECTIVE: Several mortality prediction scores are available for patients with 
upper gastrointestinal bleeding who visited the emergency department; however, 
most of the available scores include endoscopic data. Endoscopy is difficult or 
impossible to access for many emergencies departments worldwide. The aim of this 
study was to evaluate and compare the performance of the albumin, INR, 
alteration in mental status, systolic blood pressure and age 65 score and the 
Glasgow-Blatchford score in predicting mortality in patients with upper 
gastrointestinal bleeding who visited the emergency department and for which 
endoscopic data were not required.
METHODS: The data of patients with acute upper gastrointestinal bleeding who 
visited the emergency department during the study period were retrospectively 
analyzed. The data were obtained from the hospital automation system using the 
international classification of disease codes via computer registration. The 
prediction accuracy of AIMS65 and Glasgow-Blatchford score was compared using 
the area under the receiver operating characteristic curve method.
RESULTS: There were 422 patients in total; the mean age of these patients was 
68.5 while 62.6% were males. The mortality rate was 30 (7.1%). The AIMS65 score 
performed better with an AUC 0.706 [95%CI 0.660-0.749; p<0.001] compared with 
the Glasgow-Blatchford score (AUC 0.542; 95%CI 0.4693-0.576; p=0.11).
CONCLUSION: In this study, it was revealed that AIMS65, which is a score that 
can be easily calculated only with the data in the emergency department, 
outperformed Glasgow-Blatchford score in predicting mortality in patients with 
acute upper gastrointestinal bleeding who visited the emergency department.
