HAS-BLED Score

HAS-BLED Score — Bleeding Risk
Criteria No (0) Yes (+1)
HHypertension (uncontrolled SBP >160) 1
A — Abnormal renal function (dialysis, transplant, Cr >2.26) and/or liver function (cirrhosis, bilirubin >2×, AST/ALT/ALP >3×) 1 (+1 each, max 2)
S — Prior stroke 1
BBleeding history/predisposition 1
LLabile INR (unstable/high, TTR <60%) 1
EElderly (age >65) 1
DDrugs (antiplatelets, NSAIDs) and/or alcohol (≥8 drinks/week) 1 (+1 each, max 2)
HAS-BLED Score / 9
Interpretation
0–2 Low-moderate risk — Relatively low bleeding risk. Anticoagulation generally recommended if indicated.
≥3 High risk — Consider modifiable risk factors (HTN, labile INR, drugs/alcohol). Score ≥3 does NOT contraindicate anticoagulation but warrants closer monitoring.
