Objective: To compare the values of the YEARS algorithm and the simplified Wells combined with age-adjusted D-dimer (sWells-Age) algorithm in the evaluation of patients with suspected acute pulmonary embolism (APE). Methods: Patients with suspected APE receiving CT pulmonary angiography (CTPA) were enrolled from 2016 to 2017. With CTPA results as the gold standard, we evaluated and compared the performance of the two algorithms in the whole population and in symptom-onset site (in-hospital, out-of-hospital) subgroups. ⋯ Conclusions: The YEARS algorithm and the sWells-Age algorithm had a good diagnostic agreement and low failure rates and both could safely rule out APE. More patients with suspected APE could be safely excluded by the YEARS algorithm than the sWells-Age algorithm, especially in those suspected APE patients with out-of-hospital symptom-onset. However, both two algorithms were not applicable to suspected APE patients with in-hospital symptom-onset.
