Annual Bleeding Risk by Score
| Score | Annual Bleeding Risk | Category |
|---|
| 0 | 0.9% | Low |
| 1 | 3.4% | Low |
| 2 | 4.1% | Moderate |
| 3 | 5.8% | High |
| 4 | 8.9% | High |
| ≥5 | 9.1%+ | Very High |
Score = H + A(renal) + A(liver) + S + B + L + E + D(drugs) + D(alcohol)
Range: 0–9 | ≥3 = High bleeding risk
Clinical Notes:
• High HAS-BLED does not contraindicate anticoagulation — address correctable factors
• Correctable factors: uncontrolled HTN, labile INR, drugs/alcohol use
• Use in conjunction with CHA₂DS₂-VASc — net clinical benefit usually favors anticoagulation
• Reassess score after modifying risk factors
