Session Type: ACR Poster Session B
Session Time: 9:00AM-11:00AM
Background/Purpose: Psoriatic Arthritis (PsA) is an inflammatory disease with an important impact on the quality of life and work productivity. Although the activity of the disease is better controlled by the new treatments, work disability remains a frequent problem. Our objectives were to identify associated factors with work disability and fatigue in Psoriatic Arthritis and to compare Work disability and productivity loss in patients with psoriatic arthritis and rheumatoid arthritis.
Methods: A cross-sectional and observational study was conducted. Consecutive patients older than 18 years old, with diagnosis of PsA (CASPAR criteria) and RA (ACR / EULAR 2010 criteria) from 3 centers of Argentina between June 2015 and May 2016 were included.
Variables: Demographic, socio-economics, clinimetric and treatment variables were measured.
Productivity loss was evaluated with Work productivity and Activity Impairment (WPAI) questionnaire and fatigue with the first question of BASDAI. All patients with disability certificate and / or disability benefit were considered ¨disabled¨.
Results: 97 patients (37 PsA and 60 RA) were included. PsA PATIENTS: Mean age 46 ± 7.6 years, 67% females. Mean disease duration at diagnosis 62.7 ± 26.2 months and mean age at diagnosis of 40.3 ± 3.3 years. The mean fatigue value was 6.7 ± 2.4. Seventy percent were unemployed (26/37) and 11 patients were working; 62% (23) of the patients had disability certificates and 38% disability benefits (14). The mean HAQ was significantly higher in the non-working group (1.4 vs 0.6, p = 0.002). In working patients group, the mean productivity loss was 46% and mean daily life activities (DLA) commitment was 58%.BASDAI correlated significantly with greater productivity loss and greater fatigue (R = 0.64 and R = 0.86 respectively).There was no correlation between productivity loss and DAS28.
RA PATIENTS: Mean age 48.4 ± 3.7 years, 85% females. Mean disease duration at diagnosis 15.4 ± 9.6 months and mean age at diagnosis of 37.7 ± 5.3 years; 80% (48/60) of the patients were unemployed, 71.6% (43) had a disability certificate and 53.3% (32) were receiving disability benefits. There were no differences in HAQ and DAS 28 among working and unemployed patients. The percentage of productivity loss was 29% and the commitment of DLA was 60%.Higher value of EQ5D correlated with lower productivity loss (r = -0.7). Age, HAQ, DAS 28, educational level and socioeconomic status were similar in RA and PsA groups. Mean disease duration at diagnosis was higher for APs (89.7 vs 33.8 months, p = 0.02).The frequency of patients with certificate of disability, unemployed and commitment of DLA were similar in both groups.
Conclusion: In PsA patients, disease activity correlated with higher productivity loss and greater fatigue. Work disability and productivity loss were similar between Rheumatoid Arthritis and Psoriasis Arthritis patients.
