The Outpatient Bleeding Risk Index of Beyth et al

Purpose: To evaluate an outpatient being treated with warfarin for the risk of major bleeding based on the Outpatient Bleeding Risk Index of Beyth et al.

Description

Beyth et al developed the Outpatient Bleeding Risk index to identify the risk of major bleeding in an outpatient treated with warfarin. This can help identify a patient who may require closer monitoring and tighter control on anticoagulant dosing. The authors are from Case Western Reserve University.


Parameters:

(1) age of the patient in years

(2) history of stroke

(3) history of gastrointestinal bleeding

(4) number of comorbid conditions

 

Comorbid conditions included:

(1) recent myocardial infarction

(2) anemia, with hematocrit < 30%

(3) renal impairment (serum creatinine > 1.5 mg/dL)

(4) diabetes mellitus
