  Clinical Calculators - Wells Score for Probability of PE (Pulmonary Embolism)  
     
 

The Wells score for the probability of PE (pulmonary embolism) is a clinical prediction tool that estimates the probability of a patient with a suspected pulmonary embolism (PE) actually having a PE.

You must give information about all nine criteria in order to achieve a Wells score for probability of PE...

  Symptoms of DVT:      
    Yes  
    No  
         
  No alternative diagnosis better explains the illness:      
    Yes  
    No  
         
  Tachycardia (pulse >100):      
    Yes  
    No  
         
  Immobilization (>2 days) or surgery in the previous four weeks:      
    Yes  
    No  
         
  Previous history of DVT or PE:      
    Yes  
    No  
         
  Presence of haemoptysis:      
    Yes  
    No  
         
  Presence of malignancy:      
    Yes  
    No
