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.

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.
