Wicki et al developed a simple clinical score to help identify patients with a pulmonary embolism in the Emergency Department. The authors are from Geneva University Hospital in Switzerland.
(1) age of the patient in years
(2) history of pulmonary embolus (PE) or deep vein thrombosis (DVT)
(3) history of recent surgery (within past 4 weeks)
(4) pulse in beats per minute
(5) PaCO2 in kPa
(6) PaO2 in kPa
(7) chest X-ray showing plate-like atelectasis
(8) chest X-ray showing elevation of the hemidiaphragm
age of the patient
< 60 years
>= 80 years
history of PE or DVT
history of recent surgery
> 100 beats per minute
<= 100 beats per minute
< 4.8 kPa
>= 5.2 kPa
< 6.5 kPa
>= 11.0 kPa
plate-like atelectasis on chest X-ray
elevation of hemidiaphragm on chest X-ray
total score =
= SUM(points for all 8 parameters)
• minimum score: 0
• maximum score: 16
• The higher the score the more likely a pulmonary embolus is present.

Purpose: To evaluate a patient in the Emergency Department for the likelihood of a pulmonary embolus using the Geneva score of Wicki et al.
Objective: risk factors, criteria for diagnosis, severity, prognosis, stage, complications
