What proportion of patients presenting to the emergency department with chest pain undergo a formal workup for pulmonary embolism, and what factors are associated with this workup?
In patients presenting to the emergency department with chest pain, 30% undergo a formal pulmonary embolism workup, which is associated with specific clinical factors but yields a low diagnostic prevalence of 2.6%.
INTRODUCTION: Chest pain is a common main complaint in the emergency department. Among its associated differential diagnoses, pulmonary embolism remains a key concern for the clinician. There are no clear recommendations on which patients should have a formal workup for pulmonary embolism diagnosis. The objective of this study was to determine the proportion of patients with chest pain who were investigated for pulmonary embolism diagnosis and to determine the clinical profile of these patients. METHODS: This was a retrospective multicenter study conducted in three French Emergency Departments. We included all patients who presented to these centers for chest pain during a 2-month period. The primary outcome was the initiation of pulmonary embolism workup. We also aimed to find factors associated with this outcome. RESULTS: We included 881 patients with a main complaint of chest pain. Mean age was 50 years and 481 (56%) were men. A total of 263 patients (30%, 95% confidence interval 27-33%) had a formal pulmonary embolism workup, and pulmonary embolism was ultimately diagnosed in 7 cases (prevalence of 2.6%, 95% confidence interval 1.1-5.3%). Five factors were identified as independently associated with a workup for pulmonary embolism diagnosis: female sex, young age, no ischemic heart disease, recent flight and associated dyspnea. CONCLUSION: Among patients presenting to emergency department with chest pain, 30% had a workup for pulmonary embolism. We report five clinical variables independently associated with a higher probability of pulmonary embolism workup in our sample.
Lefevre-Scelles et al. (Sat,) conducted a observational in Chest pain (n=881). Emergency department presentation for chest pain was evaluated on Initiation of pulmonary embolism workup (95% CI 27-33). A formal pulmonary embolism workup was initiated in 30% (95% CI 27-33%) of emergency department patients presenting with chest pain, with a final diagnosis in 2.6%.
