OBJECTIVE: To evaluate the cost-effectiveness of telephone intervention for patients with osteoarthritis. METHODS: Randomized, controlled trial. RESULTS: The intervention did not significantly increase health care costs. The annual costs for a 1-unit improvement in physical functioning and in pain, as measured by the Arthritis Impact Measurement Scales, were 70. 86 and 31. 00, respectively. CONCLUSION: Telephone contact is a potentially cost-effective intervention in osteoarthritis.
