Tool for Assessing Bleeding Risk with Anticoagulants from The AnTicoagulation and Risk Factors In Atrial Fibrillation (ATRIA) Study
[select name="Q1" value="no (0 points)=0|YES (1 point)=1"] <-- Prior bleeding
[select name="Q2" value="no (0 points)=0|YES (2 points)=2"] <-- Age greater than 75 years
