The Wells score may refer to one of two clinical prediction rules in clinical medicine: Wells score for deep vein thrombosis; Wells' score for pulmonary embolism
While the Wells score is the predominant and most studied clinical prediction rule for DVT, [39] [115] it does have drawbacks. The Wells score requires a subjective assessment regarding the likelihood of an alternate diagnosis and performs less well in the elderly and those with a prior DVT. The Dutch Primary Care Rule has also been validated ...
The Wells score is a clinical prediction rule used to classify patients suspected of having pulmonary embolism (PE) into risk groups by quantifying the pre-test probability. It is different than Wells score for DVT (deep vein thrombosis).
The most commonly used method to predict clinical probability, the Wells score, is a clinical prediction rule, whose use is complicated by multiple versions being available. In 1995, Philip Steven Wells, initially developed a prediction rule (based on a literature search) to predict the likelihood of DVT, based on clinical criteria. [39]
An elevated D-dimer in the elderly population has no predictive value for deep venous thrombosis. Signs and symptoms of DVT in general are not sufficiently sensitive or specific to make a diagnosis, being helpful only to help determine the likelihood of a DVT (with the use of a clinical prediction rule such as the Wells score). [5]
In a prediction rule study, investigators identify a consecutive group of patients who are suspected of having a specific disease or outcome. The investigators then obtain a standard set of clinical observations on each patient and a test or clinical follow-up to define the true state of the patient.
DVT is a common cause. Thus, symptoms including leg pain, redness, and swelling can be present. [15] The likelihood of pulmonary embolism can be evaluated through various criteria. The Wells score is often calculated. It gives points based on these symptoms and patient risk factors. [13] [14]
The risk of deep vein thrombosis can be estimated by Wells score. Lower limbs venous ultrasonography is also indicated in cases of suspected pulmonary embolism where a CT pulmonary angiogram is negative but a high clinical suspicion of pulmonary embolism remains. [1] It may identify a deep vein thrombosis in up to 50% of people with pulmonary ...
