Cost-Minimization Analysis of Deep-Brain Stimulation Using National Database of Japanese Health Insurance Claims

Objectives: A new rechargeable dual-channel deep brain stimulation (DBS) system has been introduced for the treatment of Parkinson's disease and other movement disorders. However, the clinical value of the device, which has a high cost, remains unclear. Materials and Methods: We conducted a cost-minimization analysis using a national database of health insurance claims in Japan. DBS-related costs were compared between rechargeable and non-rechargeable devices and estimated across a 20-year period. Results: Although the price of rechargeable DBS was higher than that of non-rechargeable DBS, we observed total cost-savings of 8.4 million yen across 20 years by considering costs related to implantation surgery, frequency of replacement, and risk of complications. Conclusions: In this study, real-world evidence indicated that rechargeable dual-channel DBS is a reasonable choice for saving total medical costs. Price revisions should consider cost-effectiveness findings for medical devices.
