Calculate Wells Score for DVT

Active cancer (treatment ongoing, within 6 months, or palliative)

Paralysis, paresis or recent plaster immobilisation of the lower extremities

Recently bedridden for 3 days or major surgery within 12 weeks

Localized tenderness along the distribution of the deep venous system

Entire leg swollen

Calf swelling >3 cm larger than asymptomatic side

Pitting edema confined to the symptomatic leg

Collateral superficial veins (non-varicose)

Alternative diagnosis as likely or greater than that of DVT

Understanding Wells Score for DVT

The Wells Score is a validated clinical prediction rule used to assess the probability of deep vein thrombosis (DVT). It helps clinicians determine the need for further diagnostic testing.

Clinical Assessment

Combine Wells Score with D-dimer testing and clinical judgment for optimal diagnostic accuracy.

Risk Stratification

Use score to determine pre-test probability and guide further testing.

Clinical Applications

Initial Assessment

Screen patients with suspected DVT

Risk Stratification

Guide diagnostic approach

Documentation

Standardize clinical assessment

Latest Research Insights

Validation Studies

Multiple studies confirm reliability across different patient populations.

Combined Approach

Integration with D-dimer testing improves diagnostic accuracy.

Cost-Effectiveness

Reduces unnecessary imaging in low-risk patients.

Best Practices

Complete Assessment

Evaluate all criteria thoroughly

Documentation

Record findings for each criterion

Follow-up

Plan appropriate diagnostic testing

The Wells Score is a clinical prediction tool and should be used in conjunction with clinical judgment and appropriate diagnostic testing.
