Pulmonary Embolism (PE) Workup
PERC → Wells PE Score → Age-Adjusted D-Dimer
This pathway guides clinicians through the sequential evaluation of suspected pulmonary embolism in patients with low pre-test probability. It integrates the PERC rule, Wells PE scoring, and age-adjusted D-dimer interpretation — following American College of Emergency Physicians and European Society of Cardiology guidelines. Each step provides clinical context, a score, and a disposition recommendation before advancing to the next.
Pathway Steps
Pre-Test Probability Assessment
Required before applying the PERC rule
PERC Rule
Check each criterion that applies to the patient
Wells PE Score
Check each criterion that applies — note point values
Age-Adjusted D-Dimer
For low Wells PE probability — determine if D-dimer rules out PE

Always apply clinical judgment — no algorithm replaces bedside assessment.
