Notes
  • The BASDAI is a measure of disease activity in patients with spondyloarthritis. Values of at least 4 (on a scale from 0 to 10) are consistent with high disease activity. A 2-point reduction in the score resulting from therapy is considered a significant response to treatment.
  • AS: ankylosing spondylitis.

 
Equations used
 
BASDAI = ((Q1 + Q2 + Q3 + Q4) + ((Q5 + Q6) / 2)) / 5

 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
