Common questions
What does Pulmonary Embolism Pathway (Wells-PE + D-dimer) do?
Decide whether to exclude PE, order a D-dimer, or proceed to CTPA in a haemodynamically stable patient.
How is the result calculated?
Wells-PE (DVT signs 3, PE most likely 3, HR > 100 1.5, immobilisation/surgery 1.5, prior VTE 1.5, haemoptysis 1, malignancy 1); > 4 = PE likely. Age-adjusted D-dimer cut-off = age × 10 µg/L FEU for age > 50.
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
