Patient selection: adult taking low-dose aspirin therapy
Parameters:

(3) diabetes mellitus
(4) other antiplatelet drug use
(5) anticoagulant therapy

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 14 (15 in the paper, which is based on using all age points)
• A score of 0 to 1 is considered low risk for GI bleeding (less than 0.5%).
• The risk of bleeding increases as the score increases.
