Objective: To perform a cost-effectiveness analysis of mud-bath therapy (MBT) in addition to usual treatment compared to usual treatment alone in patients with bilateral knee osteoarthritis (OA). METHODS: An economic evaluation alongside a randomized controlled trial was conducted. Patients were randomly assigned to receive either a 2 weeks cycle of MBT in addition to their usual treatment or to continue routine care alone. The European Quality-of-Life Questionnaire-5 Dimensions (EQ-5D) questionnaire was administered at baseline, 2 weeks, 3, 6, 9, and 12 months. Direct healthcare resource consumption data up until 12 months were derived from a daily diary given to patients and returned at prescheduled follow-up visits. RESULTS: A total of 103 patients were included (MBT = 53, control = 50). Overall, patients in the MBT group accrued on average 0.835 (± 0.10 standard deviation, SD) quality adjusted life years (QALYs) compared to 0.753 (± 0.11 SD) in the control group (p < 0.001). Average direct costs per patient (€303 vs €975, p < 0.001) were higher in the control group, primarily because of hospitalization for total knee replacement and use of intra-articular hyaluronic acid. Bootstrapping replications of costs and QALYs sample distributions consistently indicated that the MBT therapy combined with standard therapy represents a dominant strategy vis-à-vis standard therapy alone. The probability of MBT being cost-effective at standard cost-effectiveness thresholds (e.g. 20,000€/QALY) is 100%. CONCLUSION: The results of this cost-effectiveness analysis support the use of the mud bath therapy as mid-term complementary therapy in the management of knee OA.

Abstract
Objective: To perform a cost-effectiveness analysis of mud-bath therapy (MBT) in addition to usual treatment compared to usual treatment alone in patients with bilateral knee osteoarthritis (OA). METHODS: An economic evaluation alongside a randomized controlled trial was conducted. Patients were randomly assigned to receive either a 2 weeks cycle of MBT in addition to their usual treatment or to continue routine care alone. The European Quality-of-Life Questionnaire-5 Dimensions (EQ-5D) questionnaire was administered at baseline, 2 weeks, 3, 6, 9, and 12 months. Direct healthcare resource consumption data up until 12 months were derived from a daily diary given to patients and returned at prescheduled follow-up visits. RESULTS: A total of 103 patients were included (MBT = 53, control = 50). Overall, patients in the MBT group accrued on average 0.835 (± 0.10 standard deviation, SD) quality adjusted life years (QALYs) compared to 0.753 (± 0.11 SD) in the control group (p < 0.001).
