What is the purpose of the HAS-BLED score?
The HAS-BLED score is a tool used to assess the risk of major bleeding in anticoagulated patients with atrial fibrillation. It is composed of clinical, laboratory and demographic variables that are easily obtained and can be used to estimate the risk of major bleeding within the first year of anticoagulant therapy. The score has been found to have better prediction accuracy for major bleeding compared to other scores such as the CHADS2 and CHA2DS2-VASc scores.
