PE Workup Calculator
Age, Pregnancy, YEARS? → Wells → PERC if eligible → D-dimer → Recommendation
Step 1 — Patient basics
Minimum 18. PERC requires age < 50.
PERC is not applied in pregnancy; D-dimer pathway is used.
YEARS ON → threshold 1000/500 ng/mL FEU (0 vs ≥1 YEARS items). YEARS OFF (non-pregnant) → age×10 if ≥50 (else 500).
