Model of Spyropoulos et al for Identifying a Hospitalized Medical Patient at Risk for Venous Thromboembolism on Admission

Description

Spyropoulos et al evaluated hospitalized medical patients for the risk of venous thromboembolism (VTE). A simple model using 4 parameters can identify a patient at increased risk at the time of hospital admission. The study was performed by the International Medical Prevention Registry on Venous Thromboembolism (IMPROVE) investigators.

Parameters:

(1) age of the patient in years

(2) past history of thromboembolism

(3) known thrombophilia

(4) current cancer

Parameter	Finding	Points
age of the patient in years	<= 60 years of age	0
	> 60 years of age	1
history of thromboembolism	no	0
	yes	3
known thrombophilia	no	0
	yes	3
current cancer	no	0
	yes	1

total score =

= SUM(points for all 4 parameters)

Interpretation:

• minimum score: 0

• maximum score: 8

• The higher the score the greater the risk of venous thromboembolism within the next 3 months.

Score	Observed
0 or 1	<= 0.5%
2	1.2%
3 or 4	1.6 to 1.8%
5 to 8	8%
