Overview

Wells Score Calculator for PE

This handy calculator computes the pre-test probability of pulmonary embolism using Wells criteria.[1][2][3]

Check all boxes that apply to your patient:

Clinically suspected DVT (leg swelling, pain with palpation) 3
Alternative diagnosis is less likely than PE 3
Immobilization/surgery in previous four weeks 1.5

Interpretation

Shown below is the pretest probability of PE according to Wells criteria:

  • Score >6: High probability (Rate of PE: ~66.7%)
  • Score 2-6: Moderate probability (Rate of PE: ~20.5%)
  • Score <2: Low probability (Rate of PE: ~3.6%)
