The HAS-BLED score was developed as a practical risk score to estimate the 1-year risk for major bleeding in patients with atrial fibrillation.

Major bleeding defined as any bleeding requiring hospitalization, and/or causing a decrease in hemoglobin level > 2 g/L, and/or requiring blood transfusion that was not hemorrhagic stroke.

Consider using the HAS-BLED score as a tool to potentially guide the decision to start anticoagulation in patients with atrial fibrillation.Consider comparing the risk for major bleeding as calculated by the HAS-BLED score to the risk for thromboembolic events by the CHADS2 or CHA2DS2-VASc to determine if the benefit of anti-coagulation outweighs the risk.
