The economic consequences of rheumatoid arthritis: analysis of Medical Expenditure Panel Survey 2004, 2005, and 2006 data.
OBJECTIVE
Determine the prevalence and costs of rheumatoid arthritis (RA) during three consecutive years: 2004, 2005, and 2006.


METHODS
Medical Expenditure Panel Survey was used for persons with RA. Regressions estimate health care costs and income loss. Absenteeism and age-adjusted workforce participation compared means and rates.


RESULTS
The prevalence of RA was 0.40% in 2004, 0.44% in 2005, and 0.43% in 2006. Health care cost associated with RA was $4422, $2902, and $1882 (all P < 0.01) in 2004, 2005, and 2006, respectively. Rheumatoid arthritis sufferers were employed, 36.8%, 39.5%, and 44% compared with 70.5%, 69.8%, and 71%. Individuals with RA also missed more days of work, 4.86 in 2004 (P = 0.04), 1.70 in 2005 (P = 0.22), and 2.99 in 2006 (P = 0.04). Rheumatoid arthritis reduced income by $2404 (P = 0.03), $2207 (P < 0.001), and $1212 (P = 0.002).


CONCLUSIONS
Costs of RA are considerable.
