The Wells Score is designed to assess a patient’s probability of having deep vein thrombosis (DVT).
In those with suspected DVT, a clinical assessment of probability can be useful to determine which tests to perform.
Those with Wells scores of two or more have a 28% chance of having DVT, those with a lower score have 6% odds. Alternatively, Wells scores can be categorized as high if greater than two, moderate if one or two, and low if less than one, with likelihoods of 53%, 17%, and 5% respectively.
|Wells Score Criteria Description||Points|
|Active Cancer (treatment within last 6 months or palliative)||+1 point|
|Calf swelling ≥ 3 cm compared to asymptomatic calf (measured 10 cm below tibial tuberosity)||+1 point|
|Swollen unilateral superficial veins (non-varicose, in symptomatic leg)||+1 point|
|Unilateral pitting edema (in symptomatic leg)||+1 point|
|Previous documented DVT||+1 point|
|Swelling of entire leg||+1 point|
|Localized tenderness along the deep venous system||+1 point|
|Paralysis, paresis, or recent cast immobilization of lower extremities||+1 point|
|Recently bedridden ≥ 3 days, or major surgery requiring regional or general anesthetic in the past 12 weeks||+1 point|
|Alternative diagnosis at least as likely||−2 points|
