A therapeutic bleeding risk stratification score for those on oral anticoagulants in atrial fibrillation[1]. It is matched to the CHA2DS2-VASc score used for stroke risk stratification but has not as of 2010 been externally validated.
HAS-BLED score for bleeding risk on oral anticoagulation in atrial fibrillation Feature Score if present
| Hypertension (Systolic ≥ 160mmHg) | 1 |
| Abnormal renal function | 1 |
| Abnormal liver function | 1 |
| Age ≥ 65 years | 1 |
| Stroke in past | 1 |
| Bleeding | 1 |
| Labile INRs | 1 |
| Taking other drugs as well | 1 |
| Alcohol intake at same time | 1 |
A score of 3 or more indicates increased one year bleed risk on anticoagulation sufficient to justify caution or more regular review. The risk is for intracranial bleed, bleed requiring hospitalization or a haemoglobin drop > 2g/L or that needs transfusion.
