HAS-BLED Score for Major Bleeding Risk
Estimates risk of major bleeding for patients on anticoagulation to help determine risk-benefit in atrial fibrillation care.
Points are simply added, with 1 point for each question.
There are recommendations to use the HAS-BLED Score with the CHA2DS2-VASc Score to help determine if anticoagulation is in the best interest of a particular patient. "Major bleeding" was defined in the HAS-BLED study as "intracranial, [requiring] hospitalization, hemoglobin decrease > 2 g/L, and/or transfusion."
"HAS-BLED" is an acronym for:
- Hypertension
- Abnormal Liver/Renal Function
- Stroke History
- Bleeding Predisposition
- Labile INRs
- "Elderly" (Age >e; 65)
- Drugs/Alcohol Usage
