Modified Wells Score Calculator for PE

This handy calculator computes the pre-test probability of pulmonary embolism using modified Wells criteria.

Check all boxes that apply to your patient:

Pulmonary Embolism Modified Wells Score Calculator
Variable Score
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
Previous history of DVT or PE 1.5
Tachycardia (heart rate more than 100 bpm) 1.5
Hemoptysis 1
Malignancy (treatment for within 6 months, palliative) 1

Interpretation

Shown below is the pretest probability of PE according to modified Wells criteria:[1][2]
