What is the Wells DVT prediction score for a patient with +4 cm calf pitting edema, a history of DVT, and localized tenderness?

The Wells DVT prediction score is a clinical tool used to estimate the probability of deep vein thrombosis (DVT) in a patient based on specific clinical criteria. In this case, the patient presents with calf pitting edema of greater than 4 cm, which can indicate swelling often associated with DVT.

Additionally, the presence of a history of DVT adds a significant weight to the score, as patients who have had a DVT previously are at increased risk for recurrence. Localized tenderness in the area of the swollen calf further supports the likelihood of a DVT, as this finding is often correlated with the condition.

According to the Wells scoring system, the criteria contributing to the score for this patient include:

• +4 cm calf edema (1 point)

• Previous DVT (1 point)

• Localized tenderness (1 point)

Overall, the criteria add up to a total score of 3 based on the information provided. However, if we take into consideration other potential elements from the Wells criteria, such as potential recent surgery, trauma, or immobility, the score could be elevated. If this patient presented with additional risk factors, such as having an active malignancy or being bedridden due to recent surgery or illness,
