Utrecht Bleeding Risk Score During Treatment of Acute Venous Thromboembolism

 

Parameters:

(1) WHO performance status (same as ECOG)

(2) history of bleeding

(3) history of recent trauma or surgery

(4) body surface area in square meters

 

Parameter	Finding	Points
WHO performance status	WHO grade 0 or 1	0
	WHO grade 2	1
	WHO grade 3 or 4	2
history of bleeding	absent	0
	present	2
recent trauma or surgery (< 2 months)	absent	0
	present	1
body surface area	< 1.7 square meters	2
	1.7 to 2.0 square meters	1
	> 2 square meters	0

 

where:

• The WHO performance status is the same as the ECOG scale.

• The body surface area is calculated using Mosteller's equation

 

body surface area in meter squared =

= square root ((height in cm) * (weight in kg) /3600))

 

Utrecht bleeding risk score =

= (points for WHO performance status) + (points for bleeding history) + (points for recent trauma) + (points for body surface area)

 

Interpretation:

• minimum score 0

• maximum score 7

• low risk for bleeding: <= 2 points

• middle risk for bleeding: 3 or 4 points

• high risk for bleeding: >= 5 points

 

Limitations:

• The score is not useful to identify patients at risk of minor bleeding.
