Bilateral Hearing Loss

Main objective: For a bimodal fitting (hearing aid (HA) + cochlear implant (CI)): Comparison of a tonotopy based fitting strategy (TFS4) to a default fitting strategy (FS4) for the speech recognition in noise. Secondary objectives: Comparison of TFS4 to FS4 for speech recognition in quiet. Comparison of TFS4 to FS4 for the auditory skills experienced by the subject.

This research study is evaluating two different methods of cochlear implant (CI) insertion - robotic-assisted insertion and manual insertion - to better understand how they affect hearing outcomes. Participants in this study will be randomly assigned to receive their cochlear implant using one of these two techniques. Both methods are performed in a standard operating room by qualified surgeons, and both are considered safe and approved for use. The main goal is to compare how well participants hear one year after surgery based on the insertion method used. The study will also look at things like surgical time, inner ear health, and how the hearing nerve responds. All participants will receive the same type of cochlear implant device and follow-up care. This study may help guide future surgical techniques and improve outcomes for individuals receiving cochlear implants.

Hearing loss is a major public health concern due to its negative association with emotional well-being, cognition, and physical ailments, such as diabetes. Access to audiologists and otolaryngologists in many regions across the US is poor or extremely limited. Rural populations are older, less educated, and have lower household incomes compared to populations in metropolitan areas. Also, with increasing age adults experience greater rates of hearing loss. Fortunately, the 2022 FDA Final Rule for Over-the-Counter Hearing Aids (OTC HAs) could revolutionize assess to hearing aids and hearing healthcare by allowing adults with perceived mild-to-moderate hearing loss to purchase these devices over the counter, without medical clearance or care from an audiologist. Pharmacies located in rural areas now have the option to provide OTC HAs, something previously not possible. Currently, however, there are no established guidelines for effective provision of these devices in pharmacies located in rural communities. Educating pharmacy technicians to provide basic hearing healthcare related to OTC HAs use could address a critical need and create a new care delivery model to ensure sustainable, long-term access to hearing healthcare. The long-term goal of this study is to create a sustainable interprofessional collaborative between audiologists and pharmacists for the development of a hearing healthcare model that improves access and affordability of care in rural regions across the country. The specific aims are to 1) Determine an effective approach for educating pharmacy technicians for the provision of OTC HAs in rural community pharmacies, and 2) Identify satisfaction of care provided by pharmacy technicians and initial performance with OTC HAs in adults with hearing loss living in rural communities. A stepped wedged clinical trial design will be used to study the effectiveness of a comprehensive educational training program for pharmacy technicians. Technicians from rural Alabama and Mississippi, placed within four different clusters, will participate in a multimodal training program for the purpose of developing basic clinical skills to assist adults with perceived mild-to-moderate hearing loss. Additionally, adults with hearing loss who receive clinical services from trained pharmacy technicians will be asked to report on the care they received and benefit from their OTC HAs. The central hypotheses are a) that pharmacy technician training will result in greater understanding of hearing healthcare concepts compared to no training, and b) the training will lead to successful provision of basic hearing healthcare to adults with hearing loss in rural communities. The expected outcome of this project will be the establishment of a multimodal education program, leveraging the increased access of OTC HAs, to support those with hearing loss in rural pharmacies across the county. The ability of pharmacy technicians to provide this support will dramatically increase the availability of hearing services in rural communities, which will positively impact the quality of life for those with hearing loss.
