scoring systems to assess the risk of bleeding secondary to warfarin

Q: All of the following are the scoring systems to assess the risk of bleeding secondary to warfarin intake in atrial fibrillation patients except? 

 A) ATRIA 
 B) HAS-BLED 
 C) OBRI 
 D)HEMORR2HAGES 
E) CURB 65


Answer: E

Except for CURB 65 all other (choices A, B, C, D) are the scoring systems to assess the bleeding risk in patients receiving warfarin for atrial fibrillation.

CURB 65 is a severity score to estimate the mortality risk from community-acquired pneumonia and is utilized as a determination tool to decide between inpatient vs outpatient treatment.
