Methods. Three-hundred and twenty patients with early (1 year) RA were assessed at regular intervals. Clinical and laboratory data were collected and patients reported health-care utilization and number of days lost from work. At 3-month follow-up, patients were divided into two groups according to disease activity, using DAS-28 with a cut-off level at 3.2. Direct and indirect costs and EuroQol-5D over the following 4 years were compared between the groups. Multivariate regression models were used to control for possible covariates. Results. Three months after diagnosis, a DAS-28 level of epsilon 3.2 was associated with high direct and indirect costs over the following 4 years. Patients with DAS-28 epsilon 3.2 at 3-month follow-up had more visits to physician, physiotherapist, occupational therapist and nurse, higher drug costs, more days in hospital and more extensive surgery compared with patients with 3-month DAS-28 less than 3.2. Number of days lost from work due to sick leave and permanent work disability was also higher in this group. The effect of disease activity on health-related quality of life was highly significant. In regression models, DAS-28 at 3-month follow-up was significantly associated with costs over the following years. Conclusions. Three months after diagnosis, DAS-28 is an important prognostic marker regarding health-care utilization and costs. Achieving remission or low disease activity 3 months after diagnosis is likely to decrease morbidity, increase quality of life and save costs for the patient and for society over the following years.
