Key result
Age-adjusted D-dimer threshold safely reduces the need for CTPA in suspected PE.
Why the study?
This article evaluates whether an age-adjusted D-dimer threshold can safely reduce the need for CT pulmonary angiography in patients with suspected pulmonary embolism.
Does an age-adjusted D-dimer threshold safely reduce the need for CT pulmonary angiography in patients with suspected pulmonary embolism?
Does an age-adjusted D-dimer threshold safely reduce the need for CT pulmonary angiography in patients with suspected pulmonary embolism?
Using an age-adjusted D-dimer threshold safely reduces the need for CT pulmonary angiography in patients with suspected pulmonary embolism, decreasing unnecessary imaging, costs, and risks.
Answers are grounded in this paper and cite their sources.
May reduce unnecessary CTPA in suspected PE; leaves open need for prospective validation before practice change.
Evidence shows that an age-adjusted D-dimer threshold can safely reduce the need for CT pulmonary angiography in diagnosing PE, leading to fewer unnecessary imaging tests and related cost and risk benefits.
