Geneva rule in the clinical prediction of pulmonary embolus (PE)

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Authoring team

Wells et al developed a simple clinical model which was able to predict the possibility of a patient having a PE.

It contained 7 variables with a total score of 12.5 points

  • predisposing factors
    • previous DVT or PE - 1.5 points
    • recent surgery or immobilization - 1.5 points
    • cancer - 1 point
  • symptoms
    • haemoptysis - 1 point
  • clinical signs
    • heart rate >100 beats/min - 1.5 points
    • clinical signs of DVT - 3 points
  • clinical judgement
    • alternative diagnosis less likely than PE - 3 points

The clinical probability can be divided according to the points scored into:

  • three-category scheme
    • low 0-1 points
    • intermediate 2-6 points
    • high 7 or more points
  • two-category scheme
    • PE unlikely 0-4 points
    • PE likely >4 points
