Simplified Wells Clinical Prediction Rule for Pulmonary Embolism see also - Wells DVT calculator and see also - Original Wells PE calculator and see also PERC score (useful for ruling out PE if Wells Risk is Low)
Clinical Features:
<-- Clinical symptoms of DVT?
<-- Other diagnosis less likely than PE?
<-- Heart rate greater than 100 beats per minute?
<-- Immobilization or surgery in the last 4 weeks?
<-- Previous DVT or PE?
<-- Hemoptysis?
<-- Malignancy?
Score: score=(DVT)+(Alternative)+(Rate)+(Immobilization)+(Previous)+(Hemoptysis)+(Malignancy) --> Interpretationscore=(DVT)+(Alternative)+(Rate)+(Immobilization)+(Previous)+(Hemoptysis)+(Malignancy);score>1?'Risk of PE is not low':'Risk of PE is low'
