Session Type: ACR Poster Session B
Session Time: 9:00AM-11:00AM
Background/Purpose: Inflammatory diseases such as rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA), including ankylosing spondylitis (AS) and non-radiographic axSpA (nr-axSpA), can impact significantly on patients’ (pts’) ability to perform work-related tasks in both paid employment and the household.1,2 Previous results show improvements in work and household productivity with certolizumab pegol (CZP) in pts with established RA,3,4 PsA5 and axSpA.6 We examined the comparative economic burden of RA, PsA and axSpA and the impact of CZP on productivity after 1 year (yr) in pts of working age.
Methods: Baseline (BL) and 1 yr data from: RA: PREDICT (NCT01255761),3 RAPID 1 (NCT00152386),4 RAPID 2 (BL data only, NCT00160602);4 PsA: RAPID-PsA (NCT01087788);5 axSpA: RAPID-axSpA (NCT01087762).6 Pts received CZP loading dose (400 mg at Weeks [Wks] 0, 2, 4), followed by 200 mg Q2W+MTX (RA), or 200 mg Q2W or 400 mg Q4W (PsA/axSpA). The arthritis-specific Work Productivity Survey (WPS),7 administered Q4W from BL, assessed the impact of disease on workplace and household productivity. Disease burden at BL and WPS responses (LOCF imputation) over 52 wks (RA) and 48 wks (PsA/axSpA), in CZP-treated pts stratified by age and employment status, are summarized descriptively.
Results: At BL, 582/1372 (42%) RA pts, 166/273 (61%) PsA pts, and 157/218 (72%) axSpA pts were employed outside the home. BL demographics were typical of each disease population; mean age of employed pts and pts unemployed due to arthritis/other conditions was similar (Table). Employed pts reported similarly high disease burden at BL across RA, PsA and axSpA (Table); by age, highest absenteeism was in pts aged 35–45 yrs (mean days/month: 3.1 [RA], 2.3 [PsA]) and 25–35 yrs (mean days/month: 2.4 [axSpA]) and presenteeism in pts under 35 yrs (mean days/month: 7.7 [RA], 6.5 [PsA], 7.1 [axSpA]). Compared to employed pts, unemployed pts reported a higher burden on household work and social activities, with highest burden in pts unemployed due to arthritis (Table). Similar improvements were seen in work and household productivity after 1 yr of CZP treatment, regardless of employment status, across all diseases (Table).
Conclusion: RA, PsA and axSpA pts of working age reported comparably high burden of disease on work and household productivity at BL; household burden was greater in disease-disabled pts. CZP treatment leads to comparable improvements in work and household productivity over 1 yr across RA, PsA and axSpA employed and disease-disabled pts. References: 1. Mau W.
