AIMS65 Score for Upper GI Bleeding Mortality
Determines risk of in-hospital mortality from upper GI bleeding
Altered mental status is defined as Glasgow Coma Scale (GCS) score <14 or a physician designation of “disoriented,” “lethargy,” “stupor,” or “coma.”
Reference
Summary
Usage
Summary
The AIMS65 score was designed to predict mortality in adults presenting with acute upper GI bleeding (Saltzman, 2011).
- Simple calculation
- Does not rely on endoscopic data
- Highly predictive of mortality, cost and length of stay
Summary
AIMS65 Score
- Designed to predict mortality in adults presenting with acute upper GI bleeding.
- Does not rely on endoscopic data
Criteria
There are 5 equally weighted risk factors that cumulatively predict severity of upper GI bleeding.
- Albumin <3 g/dL (30 g/L)
- INR > 1.5
- Alteration in mental status
- sBP ≤ 90 mm Hg
- Age ≥ 65 years
Rules
| AIMS65 Score | In-hospital Mortality Rate |
| 0 | 0.3% |
| 1 | 1.2% |
| 2 | 5.3% |
| 3 | 10.3% |
| 4 | 16.5% |
| 5 | 24.5% |
Notes
- Validations studies demonstrate that AIMS65 is superior to the Glasgow-Blatchford Score (GBS) and the Pre-endoscopy Rockall Score for predicting in-hospital mortality, ICU admission, and Length of Stay (Robertson, 2016).
- For low risk bleeding, a low AIMS65 score should not be used to dictate discharge (Yaka, 2015). The GBS has shown greater sensitivity and negative predictive value for low bleed risk.
- GBS may be superior to the AIMS65 in predicting need for intervention or rebleeding (Stanley, 2017)
- Albumin is the single most predictive factor of mortality of the 5 criteria.
