DASH Score


The DASH score is used to calculate the risk of recurrent VTE in an individual with a recent VTE event and who has completed a 3-6 month course of anticoagulation.  The DASH score was developed based upon individuals who had received treatment with a Vitamin K Antagonist [e.g. warfarin] rather than a DOAC.

Individuals with a DASH score of ≤1 have a low risk of annual recurrence whilst those with a DASH score of ≥ 2 have an increased risk of VTED and this may be an indication for indefinite anticoagulation.
