A 2007 clinical practice guideline from the American Academy of Family Physicians (AAFP) and the American College of Physicians (ACP) recommends that validated clinical prediction rules be used to estimate pretest probability of pulmonary embolism (PE) and to interpret test results. [4] The guideline, Current Diagnosis of Venous Thromboembolism in Primary Care, advocates use of the Wells prediction rule for this purpose but notes that the Wells rule performs better in younger patients without comorbidities or a history of venous thromboembolism (VTE) than in other patients.
