Clinical Overview

The HAS-BLED score is a widely used clinical tool designed to assess the 1-year risk of major bleeding in patients with atrial fibrillation receiving oral anticoagulation. It assists clinicians in identifying modifiable bleeding risk factors and scheduling closer follow-ups for high-risk individuals.

Clinical Pearl

A high HAS-BLED score (≥3) is NOT a contraindication to anticoagulation. The ischemic stroke risk usually outweighs the bleeding risk. The primary utility of this score is to identify and correct modifiable factors (e.g., uncontrolled hypertension, concomitant NSAID use, excessive alcohol intake).

Pitfalls & Warnings

  • The 'Labile INRs' criterion only applies to patients currently on a Vitamin K Antagonist (e.g., Warfarin); it should be scored 0 for those on DOACs or initiating therapy.
  • Subjective criteria like 'elderly (>65)' differ slightly from the CHA2DS2-VASc age cutoffs.
