| Variable | Score[1] |
| Active gastric or duodenal ulcer | 4.5 |
| Prior bleeding within the last 3 months | 4 |
| Thrombocytopenia (<50x109/L) | 4 |
| Age ≥ 85 years | 3.5 |
| Liver failure (INR>1.5) | 2.5 |
| Severe kidney failure (GFR< 30 mL/min/m2) | 2.5 |
| Admission to ICU or CCU | 2.5 |
| Central venous catheter | 2 |
| Rheumatic disease | 2 |
| Active malignancy | 2 |
| Age: 40-84 years | 1.5 |
| Male | 1 |
| Moderate kidney failure (GFR: 30-59 mL/min/m2) | 1 |
Interpretation of the IMPROVE Bleeding Risk Score

- Score ≥7: Elevated risk of bleeding
- Score <7: Not elevated risk of bleeding
