AIM: To evaluate the applicability of AIMS65 scores in predicting outcomes of 
peptic ulcer bleeding.
METHODS: This was a retrospective study in a single center between January 2006 
and December 2011. We enrolled 522 patients with upper gastrointestinal 
haemorrhage who visited the emergency room. High-risk patients were regarded as 
those who had re-bleeding within 30 d from the first endoscopy as well as those 
who died within 30 d of visiting the Emergency room. A total of 149 patients 
with peptic ulcer bleeding were analysed, and the AIMS65 score was used to 
retrospectively predict the high-risk patients.
RESULTS: A total of 149 patients with peptic ulcer bleeding were analysed. The 
poor outcome group comprised 28 patients [male: 23 (82.1%) vs female: 5 (10.7%)] 
while the good outcome group included 121 patients [male: 93 (76.9%) vs female: 
28 (23.1%)]. The mean age in each group was not significantly different. The 
mean serum albumin levels in the poor outcome group were slightly lower than 
those in the good outcome group (P = 0.072). For the prediction of poor outcome, 
the AIMS65 score had a sensitivity of 35.5% (95%CI: 27.0-44.8) and a specificity 
of 82.1% (95%CI: 63.1-93.9) at a score of 0. The AIMS65 score was insufficient 
for predicting outcomes in peptic ulcer bleeding (area under curve = 0.571; 
95%CI: 0.49-0.65).
CONCLUSION: The AIMS65 score may therefore not be suitable for predicting 
clinical outcomes in peptic ulcer bleeding. Low albumin levels may be a risk 
factor associated with high mortality in peptic ulcer bleeding.
