The Wells Criteria for Deep Vein Thrombosis (DVT) is a clinical prediction rule used to assess the probability of deep vein thrombosis (DVT) in patients presenting with symptoms suggestive of DVT. Deep vein thrombosis is a condition in which a blood clot forms in one of the deep veins, most commonly in the legs. It can lead to serious complications, including pulmonary embolism (PE), if the clot travels to the lungs.

Use Cases Limitations Evidence Owner's Insight

The Wells DVT Criteria can be applied in outpatient and emergency settings. By categorizing patients as low risk and confirming a negative d-dimer, clinicians can skip the ultrasound (US) examination to exclude the possibility of DVT.

The Wells Score is of limited utility in patients who are already admitted to the hospital.

Based on the paper: https://pubmed.ncbi.nlm.nih.gov/7752753/

Conventional DVT testing involved multiple leg ultrasounds, consuming time and costs. Wells DVT criteria can identify patients unlikely to have DVT. Additional d-dimer testing can safely rule out DVT without ultrasound.
