Purpose. To describe healthcare consumption and costs prior to, during, and after multidisciplinary rehabilitation due to arthritis. Methods. 306 patients (age 18-75 years) with arthritis scheduled for multidisciplinary rehabilitation care in 9 rehabilitation centres and 4 rheumatology hospital departments were included and followed for 6 months. Costs were estimated in Euros (€) for the total sample and five clinical subgroups. Results. Healthcare costs ranged from €3,033 to €91,336 and were significantly higher at hospital departments compared to rehabilitation centres: €9,722 (SD 5,406) and €4,250 (SD 1,040). While total costs prior to and after rehabilitation were stable for those receiving rehabilitation at a hospital, there was a significant increase in costs for those being at a rehabilitation centre. Total mean costs were more than doubled when including social costs: from €32,410 (95% CI 20,074-37,017) to €51,491 (95% CI 49,055-61,657). Conclusions. Healthcare and social costs for arthritis rehabilitation were substantial both before and after a rehabilitation stay. It is important to explore methods to reduce the length of rehabilitation stay and production loss connected to rehabilitation of patients with rheumatic disease.
