A score of 3 or more indicates an increased one year risk of bleeding on anticoagulation. Caution and regular review are recommended, as well as efforts to correct the potentially reversible risk factors. A high HAS-BLED score per se should not be used to exclude patients from oral anticoagulation (OAC) therapy.
