Wells’ Criteria for DVT

Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use, so you may find the language more technical than the condition leaflets.

The Wells’ DVT Criteria can be used in the outpatient and emergency department setting. By risk stratifying to low risk (Wells’ Score <2) and a negative D-dimer, the clinician can exclude the need for ultrasound (US) to rule out DVT.

Go to the MDCalc Wells’ Criteria for DVT.

Notes

  • There is an overall low prevalence of DVT in patients where there is low (<25%) clinical suspicion.
  • The Wells' Score inherently incorporates clinical gestalt with a minus 2 score for alternative diagnosis more likely.
  • Sequelae from DVT include pulmonary embolism (PE) and pulmonary hypertension, which have an associated mortality of 1-8%.
  • Anticoagulation is the mainstay treatment for DVT with its own associated risks of bleeding.
