Rheumatoid arthritis (RA) is a chronic inflammatory disease with a profound impact on a person’s working life. Besides permanent work disability and sick leave, at-work productivity is often impacted by RA. It was shown that reduced at-work productivity has the greatest impact on costs for RA patients, followed by wage loss from stopping or changing jobs, decreased hours, and finally missed work days (absenteeism). At-work productivity decreases when a person is present at work, but is limited in meeting work demands. The Care for Work intervention program is a multidisciplinary intervention with the aim to improve at-work productivity. The intervention program consists of integrated care, coordinated by a clinical occupational physician, and a participatory workplace intervention, coordinated by an occupational therapist. The intervention was evaluated in a randomized controlled trial (RCT) which includes 113 participants. The ojectives of this study were to determine the effects of the intervention program on work productivity, work instability, and supervisor support after 6 months of follow up in workers with rheumatoid arthritis compared to usual care.


This study is an RCT. Participants were RA patients who are involved in paid work for at least 8 hours per week, recruited from outpatient clinics of rheumatology. Outcome measures were at-work productivity (measured with the Work Limitations Questionnaire, a higher score indicates more limitations at work), work instability (measured with the RAWIS, a higher score indicates more work instability), and supervisor support (measured with the subscale Supervisor Support of the Job Content Questionnaire, a higher score indicates more supervisor support). Data were analyzed using linear regression models according to the intention-to-treat principle.


The intervention program did not show an effect on at-work productivity (B: 0.328, 95% CI -0.560 – 1.217), work instability (B: -0.697, 95% CI -2.05 – 0.66), and supervisor support (B: 0.10, 95% CI -0.12 – 0.32).


The intervention program did not show beneficial effects on at-work productivity, work instability and supervisor support after 6 months.
