Description

Ruiz-Gimenez et al developed a simple score for identifying a patient at risk for major bleeding associated with anticoagulation therapy for acute venous thromboembolism. The authors are participating in the RIETE Registry (Spain, Italy, France, Argentina, Israel)..


 

Patient selection: acute venous thromboembolism with anticoagulation therapy (initially LMW or unfractioning heparin, long-term LMWH or anti-vitamin K drug)

 

Outcome: bleeding within 3 months of starting anticoagulation therapy.

 

Parameters:

(1) age in years

(2) history of recent major bleeding

(3) serum creatinine in mg/dL

(4) anemia

(5) cancer

(6) clinically overt pulmonary embolism (PE)

= SUM(points for all 6 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 8

• The higher the score the greater the risk of major bleeding.
