DASH Score (Recurrent VTE)

Weighted predictors sum to 0–9; interpret annual recurrence risk categories.

Calculator

Check each factor that applies after the index VTE event:

Abnormal D-dimer after anticoagulation stop (+2) Age <50 years at index event (+1) Male sex (+1) Hormone therapy (estrogen) at time of index VTE (+1) Active cancer at index event (+2) First unprovoked VTE (no major transient risk factor) (+2)

DASH score

How it works

The DASH score estimates risk of recurrent venous thromboembolism after stopping anticoagulation using readily available clinical variables.

Limits

Derived in selected cohorts; does not replace shared decision-making, imaging, or guideline-directed duration of anticoagulation.
