Pharmacoeconomics of drug therapy for rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic inflammatory disease that results in progressive functional limitation, physical disability and premature death. RA extracts a considerable economic toll, particularly in terms of indirect costs related to lost productivity and premature mortality. Given these considerations, any therapy for RA that slows or prevents disability would be expected to confer economic benefit. Determination of drug efficacy does not automatically imply economic benefit, however. Establishment of economic benefit requires a rigorous analysis of both the benefits and the total costs of a given therapy The cost of drug therapy, including treatment of side-effects, currently constitutes only 15% of the total direct cost of RA, so it is important to assess other costs in any economic analysis. Common guidelines with regard to methods, units and data treatment are necessary to permit comparison of the economic benefit of different therapies within and across disease states. Such guidelines are being established for economic evaluations of medical interventions in RA. Application of these guidelines to future pharmacoeconomic studies of RA therapy will permit more accurate assessment of the economic benefit of such treatments. Given the current fiscal constraints on health care, demonstration of economic benefit will become an increasingly important factor for drug acceptance.
