Introduction:
The aim of this study was to characterize employment, work productivity, and biologic disease-modifying anti-rheumatic drug (bDMARD) treatment in a predominantly female population of axial spondyloarthritis (axSpA) patients in a real-world setting.
Methods:
This was a cross-sectional study of axSpA participants within the ArthritisPower registry. Outcomes were assessed with surveys (Work Productivity and Activity Impairment [WPAI], Bath Ankylosing Spondylitis Disease Activity Index [BASDAI], and Patient-Reported Outcomes Measurement Information System instruments) and compared between subgroups (employed vs. not employed; taking vs. not taking a bDMARD).
Results:
Among the 195 participants, 117 (60.0%) were employed and 78 (40.0%) were not employed entirely or partially due to axSpA. The mean age of the participants was 47.6 years and 86.7% were female. Current bDMARD use was reported by 57.4% of those surveyed (59.8% employed vs. 53.9% not employed; p = 0.408). Compared to not employed participants, employed participants had more favorable disease activity (BASDAI 6.0 vs. 7.6; p < 0.001) and overall health (self-rated health 2.5 vs. 1.8; p < 0.001). Employed participants, compared to not employed participants, were diagnosed at an earlier age (36.0 vs. 42.5 years, respectively) and experienced a shorter time between symptom onset and diagnosis (9.5 vs. 13.6 years, respectively). Employed participants reported missing on average 6.5 days of work and experienced a 52.7% impairment on work productivity due to axSpA over a 3-month period. Absenteeism and presenteeism were statistically similar between participants taking a bDMARD versus those not taking a bDMARD.
Conclusions:
Although bDMARD treatment rates were similar between employed and not employed participants, disease activity and overall health were better in employed than non-employed participants. Employed participants experienced substantial work productivity impairment due to axSpA.
