Two Tier Wells Criteria[1]
- Score 0-4 = PE Unlikely (12.1% incidence of PE)
- Check D-dimer
- If D-dimer positive then obtain CTPA or V/Q scan
- If D-dimer negative, no further workup needed (0.5% incidence of PE at 3 month follow up)
- Check D-dimer
- Score >4 = PE Likely (37.1% incidence of PE)
- Obtain CT Pulmonary Angiography or V/Q Scan
