Aim

To estimate the sick leave and disability pension trajectory in patients diagnosed with early RA 1999-2007

and the burden of sick leave and disability pension in prevalent patients with RA in 2007

Ver2011 07 13

Methods• Incident RA Cohort (n=3,029)

Individuals aged 19-59y diagnosed with early RA were identified in the Swedish Rheumatology Quality Register (1999-2007; mean age 47y; 73% women)

• Prevalent RA Cohort (n=25,922)19-64y old prevalent patients in 2007 were identified in the National Patient Register & Swedish Rheumatology Quality Register (mean age 52y; 73% women)

• OutcomeSick leave & disability pension data were retrieved from national registers

• Matched ComparatorsFor each patient, five age-, sex-, education-, and county-matched general population comparators were sampled (5 comparators available for 25,551 patients with RA)

Results1. Prevalent RA– Annual days of sick leave & disability pension in 2007– Economic burden

2. Incident RA: Development in relation to diagnosis– By month -12m to +12m– By year -4y to +4y– By calendar period

ConclusionDespite better drugs and improved treatment strategies, data from contemporary patients with early and established RA continue to indicate large unmet needs
