Interactive Wells' Criteria for Pulmonary Embolism calculator. Requires the calculator gadget.

Usage: {{Wells PE Calculator}}

Wells' PE Score Calculator
Criteria	No	Points
Clinical signs and symptoms of DVT (leg swelling, pain with palpation)	1	+3.0
PE is #1 diagnosis OR equally likely	1	+3.0
Heart rate >100 bpm	1	+1.5
Immobilization (≥3 days) OR surgery in previous 4 weeks	1	+1.5
Previous objectively diagnosed PE or DVT	1	+1.5
Hemoptysis	1	+1.0
Malignancy (treatment within 6 months or palliative)	1	+1.0
Wells' Score	points

Three-Tier Model
0–1	Low Risk — 1.3% incidence of PE. Consider D-dimer to rule out. Consider PERC rule.
2–6	Moderate Risk — 16.2% incidence of PE. Consider high-sensitivity D-dimer or CTA.
>6	High Risk — 37.5% incidence of PE. Consider CTA. D-dimer not recommended.

Two-Tier Model (Preferred by guidelines)
0–4	PE Unlikely — 12.1% incidence. Consider high-sensitivity D-dimer; if negative, stop workup.
>4	PE Likely — 37.1% incidence. Consider CTA testing.
