Session Type: Poster Session (Sunday)
Session Time: 9:00AM-11:00AM
Background/Purpose: Axial spondyloarthritis (axSpA) usually affects young people and may lead to work disability(WD). We used the “Smart-phone SpondyloArthritis Management System”, an interactive mobile health tool to evaluate clinical characteristics and the status of work ability disorders, to determine the prevalence of axSpA unemployment due to illness and the loss of work efficiency, and to analyze the association between the clinical characteristics and WD in patients with axSpA.
Methods: 1187 patients with axSpA were included. WD was assessed with the Work Productivity and Impairment questionnaire (WPAI) reporting WD as the absenteeism, presenteeism, overall work impairment and activity impairment. Demographic properties, pharmacotherapy, co morbidities, disease activity (BASDAI and ASDAS), functionality (BASFI),spinal mobility (BASMI), C-reactive protein, erythrocyte sedimentation rate (ESR),nocturnal pain, total back pain, patient’s global assessment of disease activity and Assessment of Spondyloarthritis International Society health index (ASAS-HI) were investigated and compared in employed and un-employed patients. Logistic regressions were used to investigate the associations between work status and clinical characteristics. The relationships between WPAI scores and disease activity were assessed using Spearman correlation coefficients.
Results: Among them, 60(5.05%) participants were unemployed. 793 patients（66.81％）were employed. Absenteeism, presenteeism, overall work impairment and activity impairment in all employed patients were 7%, 24%, 29% and 27%, respectively. The predictive factors for not being employed were suffering from inflammatory bowel disease and higher ASAS HI scores (OR value was 0.431, 0.696, respectively). Factors significantly associated with a higher absenteeism, overall work impairment and activity impairment loss were BASDAI,BASFI,ASAS HI,ASDAS, nocturnal pain, total back pain and patient’s global assessment of disease activity (r >0.5), while NSAIDs treatment were significantly associated with a lower Absenteeism loss. A decrease in work productivity was related to an increase ASDAS score.
Conclusion: We determined that axSpA had a significant influence on the working conditions and the factors related to the disease had a significant correlation with work productivity using a Smart-Phone Management System.
