Evaluation of the PERC Score and the YEARS Algorithm in the Diagnosis of Pulmonary Embolism in the Emergency Department (EP)

December 17, 2025 updated by: University Hospital, Strasbourg, France

Evaluation of the PERC Score and the YEARS Algorithm in the Diagnosis of Pulmonary Embolism in the Emergency Department: a Retrospective Observational Study in the Emergency Department of the Strasbourg University Hospital

The current diagnostic strategy for pulmonary embolism relies on clinical evaluation, followed by D-dimer testing and chest CT angiography. However, this approach leads to overuse of CT angiography. Diagnosis remains complex, with nonspecific clinical signs. Recent studies have explored new algorithms, such as the YEARS algorithm and the PERC score, which aim to support the diagnosis and reduce the need for imaging examinations. Their use could decrease waiting times in the emergency department and limit the need for additional investigations.
