Official title
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
Overview
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.
Primary outcome measures
- Number of patients who would not have required imaging if the PERC score and YEARS algorithm criteria had been applied [Time frame: Up to 12 months]
Eligibility criteria
Inclusion criteria
- Adult patient (≥18 years)
- Patient admitted to the adult emergency department of the Strasbourg University Hospital over a 6-month period (January to June 2024), for whom a D-dimer test and chest imaging (thoracic CT angiography or ventilation/perfusion scintigraphy) were performed
Exclusion criteria
\- No D-dimer test or test performed for another indication, no chest imaging (CT angiography or scintigraphy), long-term anticoagulant treatment.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
