How to Interpret
AIMS65 is a bedside score for patients admitted with upper gastrointestinal bleeding. It helps predict in-hospital mortality and need for higher-level care.
| AIMS65 score | Approx. mortality* | Risk |
|---|---|---|
| 0 | < 1% | Very low |
| 1 | ~1–3% | Low |
| 2 | ~4–6% | Intermediate (high-risk threshold) |
| 3 | ~10–17% | High |
| 4–5 | > 30% | Very high |
*Approximate ranges based on published cohorts; actual risk depends on population and comorbidities. Always use alongside full clinical assessment and local guidelines.
