Cost-utility analysis of treatment strategies in patients with recent-onset rheumatoid arthritis.

OBJECTIVE: To evaluate societal costs and quality-adjusted life years (QALYs) of treatment strategies for patients with recent-onset active rheumatoid arthritis (RA). METHODS: Patients (n = 508) were randomly allocated to 1 of 4 treatment strategy groups: sequential monotherapy, step-up combination therapy, initial combination therapy with prednisone, or initial combination therapy with infliximab. For 2 years, patients reported cost and utility measures. RESULTS: Average QALYs (ideally 2.00) for groups 1-4 were 1.29, 1.31, 1.32, and 1.41, respectively, for the British EuroQol (P
