Bleeding Risk Score of Adam et al for a Patient with Atrial Fibrillation on Oral Anticoagulants

Description

Adam et al reported a bleeding risk score for patients with atrial fibrillation who are taking an oral anticoagulant. This can help to identify a patient at greater risk for bleeding. The authors are from multiple institutions in Europe and North America.

Patient selection: atrial fibrillation, receiving an oral anticoagulant

Parameters:

(1) age in years

(2) hypertension

(3) history of cancer

(4) prior major bleed

Parameter	Finding	Points
age in years	< 75 years	0
	>= 75 years	1.5
hypertension	no	0
	yes	1.5
history of cancer	no	0
	yes	1
prior major bleed	no	0
	yes	2

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 6

Total Points	Bleeding Risk	Bleeding per 100 Patient Years
0 or 1	low	2.5
1.5 to 3	moderate	5.9
3.5 to 6	high	12.9

Performance:

• The area under the ROC curve is 0.64 (adjusted for optimism).
