Some advocate using the Wells’ score over clinician gestalt to predict who is low-risk and then applying the PERC rule to stop workup for PE. As with all clinical decision aids, the physician must first have a suspicion of the diagnosis before attempting to apply the Wells criteria.
The principal investigators of the study request that you use the official version of the modified score here. Wells’ Criteria for DVT Calculates Wells’ Score for risk of DVT.
Dec 28, 2018 · Modified Wells Scoring System. The AAFP/ACP guideline advocates use of the Modified Wells prediction rule for the above-specified estimation and interpretation requirements (see Table 1, below). However, the guideline notes that the Wells rule performs better in younger patients without comorbidities or a history of venous thromboembolism.
Scoring. A score of 0 or lower → minimal risk – DVT prevalence of 5%. D-dimer testing is safe in this group – negative d-dimer decreases the probability of disease to <1% allowing an ultrasound to be deferred. A score of 1-2 → moderate risk – DVT prevalence of 17%. D-dimer testing still effective and a negative test decreases post-test
The Wells criteria for pulmonary embolism is a risk stratification score and clinical decision rule to estimate the probability for acute pulmonary embolism (PE) in patients in which history and examination suggests acute PE is a diagnostic possibility.
The Wells score is a number that reflects your risk of developing deep vein thrombosis (DVT). DVT happens when a blood clot forms in a vein that’s deep inside your body, usually in your leg.
Wells Criteria and Modified Wells Criteria: Assessment for Pulmonary Embolism. Heart rate >100 1.5 Immobilization (≥3 days) or surgery in the previous four weeks 1.5 Previous DVT/PE (objectively diagnosed) 1.5 Moderate 2.0 to 6.0 PE unlikely ≤4.0 DVT: deep vein thrombosis; PE: pulmonary embolism. Hemoptysis = coughing up of blood or blood-stained mucus from the bronchi, larynx, …
Wells clinical prediction rule for PE produces a point score based on clinical features and the likelihood of diagnoses other than PE.
The modified (eg, dichotomous) Wells score was retrospectively calculated by reviewing each patient’s record. Requesting a D-dimer was taken to mean that alternate diagnoses were of equal or greater likelihood than acute PE.

Wells score. Jump to navigation Jump to search. The Well’s score or Well’s criteria can refer to one of two clinical prediction rules in clinical medicine. DVT probability scoring for diagnosing deep vein thrombosis. Pulmonary embolism probability scoring for diagnosing pulmonary embolism.
wells score for pulmonary embolism, Prediction scoring systems such as the Wells criteria or the modified Wells can be used to reduce the number of unnecessary ultrasound scans as well as to guide management when scans are nondiagnostic Although use of Wells, Modified Wells,
This Wells criteria for pulmonary embolism calculator predicts the probability of PE before testing or CT angiography based on clinical signs from Wells score and awards a risk percentage. You can read more on the criteria employed, the risk factors and result interpretation below the form.
