    OBJECTIVE: To evaluate the cost-effectiveness of telehealth-delivered exercise and diet-plus-exercise programs within 12 months. METHODS: An economic evaluation within a 12-month, 3-arm, parallel randomized trial of two 6-month telehealth-delivered exercise programs, with and without a dietary component. A total of 415 people with knee osteoarthritis ages 45-80 years and body mass index of 28-40 kg/m2 were assigned to 1 of 2 telehealth-delivered exercise programs, 1 without (n = 172) and 1 with (n = 175) a dietary component (ketogenic very low calorie diet), or to an education control (n = 67), for 6 months, with 6 months follow-up. The primary economic outcomes were quality-adjusted life years (QALYs) and health system costs. Measured costs were the direct intervention (consultations, equipment/resources, and meal replacements) and health care use in 2020 Australian dollars ($AU1.5 = $US1). Secondary analysis included weight loss and work productivity gains. RESULTS: The clinical trial demonstrated greater improvements in pain and function compared to information only for individuals with knee osteoarthritis and overweight/obesity. We can be 88% confident that diet plus exercise is cost effective ($45,500 per QALY), 53% confident that exercise is cost-effective ($67,600 per QALY) compared to the control, and 86% confident that augmenting exercise with the diet program is cost effective ($21,100 per QALY). CONCLUSION: Telehealth-delivered programs targeting exercise with dietary intervention for people with knee osteoarthritis who have overweight/obesity are likely to be cost-effective, particularly if potential long-term gains from weight loss and work productivity are realized.
