HAS-BLED score for bleeding risk on oral anticoagulation in atrial fibrillation |
Hypertension (Uncontrolled Systolic > 160mmHg) 1
Abnormal renal function (dialysis or creatinine over 200 mcg/L) +1
Abnormal liver function (ALP/AST/ALT > 3 times normal or bilirubin x2 normal or cirrhosis) +1
Age > 65 years +1
Stroke in past +1
Labile INRs +1
Taking other Drugs Predisposing to Bleeding (Antiplatelet agents, NSAIDs) +1
Alcohol intake at same time (over 8 units/wk) +1
|Score: Maximum possible score is 9|
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 a transfusion.
