Geneva score

The Geneva score, similarly to the Wells score, is a clinical stratifying system to estimate the probability of pulmonary embolism (PE) in patients in which this diagnosis was considered. The criteria were originally published by the clinical team of the Geneva University Hospital in 2001 1, and revised and simplified in 2006 2

Original Geneva score

It ranges from 0 to 16 points and results in 3 clinical probability categories: low, intermediate, and high risk 1.  

  • age
    • 60–79 years = 1
    • 80+ years = 2
  • history of previous venous thromboembolism: DVT or PE = 2
  • recent surgery within 4 weeks = 3
  • heart rate
    • >100 bpm = 1
  • PaCO2 (partial pressure of CO2 in arterial blood)
    • <35mmHg = 2
    • 35-39mmHg = 1
  • PaO2 (partial pressure of O2 in arterial blood)
    • <49mmHg = 4
    • 49-59mmHg = 3
    • 60-71mmHg = 2
    • 72-82mmHg = 1
  • chest X-ray
    • band atelectasis = 1
    • elevation of hemidiaphragm = 1

Probability of pulmonary embolism: 

  • low probability < 5 points
  • intermediate probability 5 - 8 points
  • high probability >8 points
Revised Geneva score  

It does not include any more arterial blood gas samples parameters, ranging now from 0 to 22 points and results in 3 clinical probability categories: low, intermediate, and high risk 2

  • age 65 years or over = 1
  • history of previous venous thromboembolism: DVT or PE = 3
  • recent surgery or fracture within 1 month = 2
  • active malignant condition = 2
  • unilateral lower limb pain = 3
  • pain on deep palpation of the lower limb and unilateral oedema = 4
  • haemoptysis = 2
  • heart rate
    • 75 - 94 bpm = 3
    • 95 bpm or more = 5

Probability of pulmonary embolism: 

  • low probability 0-3 points
  • intermediate probability 4-10 points
  • high probability >10 points
