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 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
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.
A new prediction score for PE was created in 1998 [40] This prediction rule was revised by Wells et al. in 2000. [41] In the 2000 publication, Wells proposed two different scoring systems using cutoffs of 2 or 4 with the same prediction rule, and also included D-dimer testing in the rule-out of PE in low probability patients.

Medical calculators arose because modern medicine makes frequent use of scores and indices that put physicians' memory and calculation skills to the test. [2] The advent of personal computers, the Internet and Web, and more recently personal digital assistants (PDAs) have formed an environment conducive to their development, spread and use.
Philip Steven Wells is a Canadian hematologist and current chair and Chief of Medicine at the University of Ottawa and The Ottawa Hospital. [1] He is considered an expert in thromboembolic disorders and is known for developing the Wells risk score for pulmonary embolism and deep vein thrombosis .
The Geneva score is a clinical prediction rule used in determining the pre-test probability of pulmonary embolism (PE) based on a patient's risk factors and clinical findings. [1] It has been shown to be as accurate as the Wells Score, and is less reliant on the experience of the doctor applying the rule. [2]
ThroLy score has been validated by multiple studies and entered clinical practice in several medical centers. [ 3 ] [ 4 ] [ 5 ] However, multiple validation studies are ongoing and the results of additional studies may be needed before it can be fully applicable in clinical practice worldwide; several validation studies have been performed, and ...
