Description
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.
Calculator Inputs
This calculator does not use any default mappings, all items require manual input.
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 |
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 |
