HAS-BLED Score for Major Bleeding Risk of Anticoagulation in Atrial Fibrillation A clinical mnemonic to estimate the risk of major bleeding with anticoagulation in atrial fibrillation. A higher total score indicates a greater risk of major bleeding and argues against anticoagulation. H - Hypertension (uncontrolled) A - Abnormal renal or liver function (1 point each) S - Stroke B - Bleeding (prior major bleed) L - Labile INRs E - Elderly (Age > 65) D - Drugs (Medications predisposing to bleeding, NSAIDs, anti-platelets) or Alcohol (1 point each) HAS-BLED Score - Major Bleeding Risk 0 - 0.9 % 1 - 3.4 % 2 - 4.1 % 3 - 5.8 % 4 - 8.9 % 5 - 9.1 % ≥6 - > 10% Source: https://pubmed.ncbi.nlm.nih.gov/211 #HASBLED #Score #Risk #Bleed #Anticoagulation #AFib #BLEEDING #Mnemonic #Acronym #Diagnosis
