The QRISK3 score calculates a person's risk of developing a heart attack or stroke over the next 10 years. Statin treatment is typically offered as primary cardiovascular disease prevention for individuals with a QRISK3 score of 10% or more. This tool would not be useful in the diagnosis of DVT.

The FEVERPAIN score is used to predict the likelihood of the presence of a strep throat infection and thus the need for antibiotics in its treatment. It would not be useful in the diagnosis of DVT.

Well's score lists a number of criteria which are used to determine the pretest clinical probability of a deep vein thrombosis (DVT). Zero points corresponds to a low DVT probability, and advises a D-dimer which, if negative, can reliably rule out the diagnosis. One to two points is classed as an intermediate probability, and the patient should be treated as having a DVT, and a compression USS should be performed. Scores above two are high probability and should be treated as a DVT, with a compression USS performed to confirm the diagnosis. An adapted Well's score also exists for pulmonary embolism.

The ORBIT score is used to predict the bleeding risk in patients started on anticoagulation for atrial fibrillation. It would not be used in this case as there is no sign the patient suffers from atrial fibrillation and would not aid in the diagnosis of DVT.
