About this tool

The Ankylosing Spondylitis Disease Activity Score (ASDAS) is an index to assess disease activity in Ankylosing Spondylitis (AS).

The prefered score uses CRP, rather than ESR.

ASDAS-CRP =0.12 x Back Pain + 0.06 x Duration of Morning Stiffness + 0.11 x Patient Global + 0.07 x Peripheral Pain/Swelling + 0.58 x Ln(CRP+1)

ASDAS-ESR = 0.08 x Back Pain + 0.07 x Duration of Morning Stiffness + 0.11 x Patient Global + 0.09 x Peripheral Pain/Swelling + 0.29 x â(ESR)

Back pain, patient global assessment, duration of morning stiffness and peripheral pain/swelling are all assessed on a numerical rating scale (from 0 to 10).

The 3 cut-offs selected to separate these states (figure 1) were: <1.3 between "inactive disease" and "moderate disease activity", <2.1 between "moderate disease activity" and "high disease activity", and >3.5 between "high disease activity" and "very high disease activity".

Cut-offs for improvement scores were: a change ≥1.1 units for "clinically important improvement" and a change ≥2.0 units for "major improvement".
