Wells Score Model

The Wells Score is a widely recognized clinical tool designed to assess a patient’s risk of DVT. Developed by Dr. Philip Wells, this score incorporates specific clinical criteria, with quantitative values assigned to each criterion. The concept is straightforward: the higher the score, the greater the likelihood of DVT.

The criteria include:

Active cancer (treatment ongoing, within 6 months, or palliative)
Paralysis, paresis, or recent plaster immobilization of the lower limb
Recently bedridden for 3 days or more, or major surgery
Localized tenderness along the distribution of the deep venous system
Entire leg swelling
Calf swelling of 3 cm or more than the other leg
Pitting edema confined to one leg
Previous documented DVT
Alternative diagnosis at least as likely as DVT

Each criterion contributes to the total score, which classifies patients into three risk categories: low, moderate, and high. This categorization aids in determining the next steps in management, including whether to proceed with imaging studies.

The Wells Score is a beneficial model for its simplicity and accessibility. However, while it provides valuable guidance, clinicians should use it as part of a holistic assessment that includes individual clinical judgment and additional testing where indicated.

Caprini Risk Assessment Model

The Caprini Risk Assessment Model is another pivotal tool in evaluating DVT risk. This model expands on the Wells Score by incorporating a broader range of risk factors, which enhances its utility in clinical settings.
