DASH Prediction Score — VTE Recurrence Risk After Discontinuing Anticoagulation

Predicts the annual risk of recurrent venous thromboembolism (VTE) after first unprovoked VTE following anticoagulation discontinuation. DASH score identifies patients at low enough recurrence risk to safely discontinue anticoagulation after the minimum treatment period vs. those who should continue indefinite anticoagulation.
