A therapeutic bleeding risk stratification score for those on oral anticoagulants in atrial fibrillation. It is matched to the CHA2DS2-VASc score used for stroke risk stratification but has not as of 2010 been externally validated.
|Feature||Score if present|
|Hypertension (Systolic ≥ 160mmHg)||1|
|Abnormal renal function||1|
|Abnormal liver function||1|
|Age ≥ 65 years||1|
|Stroke in past||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.
