Wells_DVT v.1
Wells’ Criteria for DVT are used for evaluating the pre-test probability for deep vein thrombosis (DVT). Utilization of the Wells’ DVT criteria can determine those patients who are overall unlikely to have a DVT. Two points or more indicate high probability for DVT.
For evaluating the pre-test probability for deep vein thrombosis (DVT). Utilization of the Wells’ DVT criteria can determine those patients who are overall unlikely to have a DVT.
The Wells’ DVT criteria can be used in outpatient as well as emergency department settings. They are only to be applied after a thorough history and physical examination resulting in a suspicion of DVT. A low risk score (<2) along with a negative test result for d-dimer excludes the need for further examination with ultrasound. The score is generated based on seven weighted criteria: - Active cancer - Paralysis, paresis, or recent plaster immobilisation of the legs - Bedridden recently ≥3 days or major surgery within 12 weeks - Localized tenderness along the deep venous system - Entire leg swollen - Calf swelling >3 cm compared to the other leg - Pitting oedema - Collateral (nonvaricose) superficial veins - Alternative diagnosis to DVT at least as likely The maximum score is 8p and a score of 2p or more suggests high probability of DVT.
Not to be used with any other formula or criteria for DVT risk stratification.
