Michael Gibson, M.S., M.D. [2] Associate Editor(s)-in-Chief: Sadaf Sharfaei M.D.[3] ## Overview[edit | edit source] The HAS-BLED score is a therapeutic bleeding risk stratification score for those on oral anticoagulants in atrial fibrillation[1]. It is recommended by the new European Society of Cardiology guidelines and the Canadian guidelines on atrial fibrillation management.[2][3] This score would help as a potential practical tool in clinical decision making, rather than 'guessing' the bleeding risk. Also, the HAS-BLED score makes clinicians think about addressing any correctable bleeding risk factors (eg. uncontrolled hypertension, coadministration of NSAIDs or aspirin, etc). It is matched to the CHA2DS2-VASc score used for stroke risk stratification. In a recent article validating the score, diabetes and left ventricular dysfunction were identified as additional risk factors for bleeding.[4] ## HAS-BLED Score Calculator[edit | edit source] ### Calculation of the HAS-BLED Score for Bleeding[edit | edit source] Please check the boxes that apply to your patient to calculate the HAS-BLED score for bleeding: HAS-BLED Score Variable | Score Age ≥ 65 years | 1 | Hypertension (Systolic Blood Pressure ≥ 160mmHg) | 1 | Abnormal renal function | 1 | Abnormal liver function | 1 | Stroke in past | 1 | Bleeding | 1 | Labile INRs | 1 | Taking other drugs as well | 1 | Alcohol intake at the same time | 1 | HAS-BLED Score: Interpretation: ### Interpretation of the HAS-BLED Score for Bleeding[edit | edit source] * 0 Score: 1.13 bleeds per 100 patient-years * 1 Score: 1.02 bleeds per 100 patient-years * 2 Score: 1.88 bleeds per 100 patient-years * 3 Score: 3.74 bleeds per 100 patient-years * 4 Score: 8.70 bleeds per 100 patient-years * 5 to 9 Score: Insufficient data (high risk) ## References[edit | edit source] 1. ↑ Pisters R, Lane DA, Nieuwlaat R, de Vos CB, Crijns HJ, Lip GY.
