Abstract
Objectives: This study aimed to evaluate the cost-effectiveness of cochlear implants in older adults with hearing impairment 65 years or older in Japan. In addition, this study aimed to establish a basis for making recommendations for cochlear implants in clinical practice for suitable patients.
Design: We conducted a cost-utility analysis using the incremental cost-effectiveness ratio (ICER) to compare unilateral cochlear implants with hearing aids. The study involved participants 65 years or older with severe-to-profound hearing loss attending two cochlear implant surgery facilities in Japan. Costs were calculated from the participants' receipt data and standard clinical paths from medical care providers. Quality-adjusted life years (QALY) were assessed by patients using the Japanese version of the Health Utilities Index Mark 3 and by medical care providers using the visual analog scale (VAS). In addition, sensitivity analyses were performed by varying the utility value, discount rate, age at implantation, and costs to estimate the ICER under different scenarios.
Results: Responses were received from 26 cochlear implant users and 8 hearing aid users. After applying the survival and discount rates to the utility values and costs, the ICER was $44,533, which falls within the acceptable willingness-to-pay threshold in Japan. Sensitivity analysis showed that the ICER was the most sensitive to the utility value, followed by the discount rate.
Conclusions: The findings indicate that providing cochlear implants to older adults with hearing impairment is not only beneficial in terms of improved hearing performance but also economically efficient.
