Assessing cost-effectiveness analyses in rheumatoid arthritis and osteoarthritis.

Economic considerations are now a source of great concern to clinicians and policy analysts. Many cost-effectiveness analyses have been published in the area of arthritis, most with substantial methodologic deficiencies. The goal of this article is to outline a method for evaluating cost-effectiveness assessment within the field of rheumatology. We do so by critically evaluating 6 cost-effectiveness analyses--2 in rheumatoid arthritis and 4 in osteoarthritis--as a basis for appraising the literature and developing future studies.
