Common questions
What does Venous Thromboembolism Anticoagulation Duration Decision do?
Use to set anticoagulation duration: short course for major transient triggers, indefinite for cancer or recurrence, and bleeding-risk-dependent for unprovoked VTE.
How is the result calculated?
Major transient → 3 months. Minor transient → ≥ 3 months, individualized. Cancer → until inactive. Recurrent → extended/indefinite. Unprovoked → extended if low-moderate bleeding (reduced-dose DOAC), stop at 3 months if high bleeding.
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
