The ankylosing spondylitis disease activity score (ASDAS) is a measure of axial spondyloarthritis (SpA) disease activity endorsed by the Assessment of SpA International Society and Outcome Measures in Rheumatology. Accumulating evidence supports the utility of ASDAS in axial SpA. So, is it time to replace the Bath ankylosing spondylitis disease activity index (BASDAI)?
