Evaluation of spondyloarthritis-specific health utility based on ASAS health index (U-ASAS-HI) among the disease subtypes: an ancillary analysis from the ASAS-PerSpA study.

ABSTRACT:

Objectives

To compare the spondyloarthritis (SpA) specific universal health utility estimation from the ASAS health index (U-ASAS-HI) with the generic EuroQol-5D-3L (EQ-5D-3L) utility among SpA subtypes and to understand the contribution of health-, personal- and country-level factors to the U-ASAS-HI.

Methods

Ancillary analysis of the ASAS-PERipheral involvement in SpondyloArthritis (PerSpA) study including patients who completed both ASAS-HI and EQ-5D-3L. Correlations between U-ASAS-HI and EQ-5D-3L were tested overall and by subtype (axial SpA, peripheral SpA and psoriatic arthritis (PsA)). Health and contextual determinants of U-ASAS-HI were evaluated using multivariable linear mixed-effects models with country as level.

Results

4158 patients were included, mean ag
