Randomized Trial of Telehealth vs Conventional Hearing Care Delivery in the ACHIEVE Study

PROJECT SUMMARY Hearing loss is a chronic condition prevalent in two-thirds of adults >70 years and may be a potentially modifiable risk factor for adverse health outcomes including dementia. However, uptake and sustained use of hearing aids in adults is low, with <20% of older adults with hearing loss reporting use, among whom up to 30- 40% may discontinue hearing aid use over time. These limitations may stem in part from the reliance of the current best-practice model of hearing healthcare (HHC) on clinic-based visits that requires multiple in-person sessions between an audiologist and a patient for all ongoing technical and self-management support services. Incorporation of asynchronous and synchronous telehealth into HHC to complement clinic-based visits would allow for routine troubleshooting of communication challenges, hearing aid technical issues, and reinforcement of self-management support strategies. Determining if a HHC model that incorporates audiological telehealth improves long-term hearing aid use and other patient-centered outcome measures has direct implications for both future clinical care standards and ongoing Medicare legislative bills pertaining to HHC coverage. Our interdisciplinary consortium of investigators has a singular opportunity to evaluate the potential benefits of a telehealth audiology model on long-term hearing aid use and other outcomes in a large cohort of racially- diverse, community-dwelling older adults who are existing hearing aid users. In the ongoing Aging & Cognitive Health Evaluation in Elders (ACHIEVE) randomized trial, we recruited 977 adults ages 70-84 with untreated mild-to-moderate hearing loss from January 2018 to October 2019 who were randomized 1:1 to a hearing intervention (i.e., conventional clinic-based delivery of hearing services and technologies) versus a successful aging education control intervention. Participants are now being followed for 3 years post-randomization at the four ACHIEVE field sites, and the goal of this NIA-funded multisite trial (R01AG055426) is to determine if hearing loss treatment versus an aging education control intervention reduces cognitive decline. From 2021- 2022, as participants in the hearing intervention group (n=490) complete their pre-specified three years of follow-up in the ACHIEVE trial, we propose to recruit these existing hearing aid users and randomize them to receive either continued conventional clinic-based delivery of hearing care services or a model that incorporates telehealth. At 1 year post-randomization, the primary outcome (hours of hearing aid use) will be contrasted between the two groups, and participants in the conventional HHC arm will then cross-over and also receive telehealth HHC. All participants will continue to be followed for 2 years post-randomization. Aim 1: To compare the effect of the telehealth versus conventional HHC delivery model on hours of hearing aid use (primary outcome) and other patient-centered hearing and communication outcomes at 1 year post- randomization. Aim 2: To compare the effect of the telehealth versus the conventional HHC delivery model on secondary outcomes of social, mental, physical, and cognitive functioning at 1 year post-randomization.
