Clinical probability score and D‐dimer estimation lack utility in the diagnosis of childhood pulmonary embolism

BACKGROUND: Childhood pulmonary embolism (PE) causes significant mortality and evidence suggests that it is under-diagnosed. Clinical probability scores and D-dimer estimation to assess pre-test probability have not been studied in children with suspected PE. PATIENTS/METHODS: This retrospective cohort study evaluated Wells simplified probability score for PE in 50 children with PE and 25 PE negative control patients, and D-dimer values in 27 …
