The HAS-BLED tool is often used to assess a patient’s bleeding risk before starting the use of anticoagulation – particularly in relation to atrial fibrillation.
It is often used in conjunction with the CHA₂DS₂-VASc score to weigh the risks and benefits of anticoagulation.
Each item is worth a single point
A score of ≥3 indicates “high risk” for bleeding if anticoagulation is used and it is recommended to either very closely follow-up the patient or consider alternatives to anticoagulation

H	Hypertension >160mmHg systolic
A	Abnormal renal or liver function
S	Previous history of stroke
B	Previous history of major bleeding
L	Labile INR
E	IV drug use (<60% of time in therapeutic range)
D	Drug and alcohol use – NSAIDs, anti-platelet agents, alcohol >8 weeks / week
