Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: Prior to the hearing evaluation, participants will be randomly placed in one of three groups. The three groups include those who will receive the current best practices care from an audiologist (ABP), those who will receive the ABP plus an aural rehabilitation program (ABP+AR), and finally, those who will receive only an OTC HA without assistance from an audiologist for providing programming, maintenance or care information (OTC-only). The AR programming will be provided by trained Community Health Advisors (CHAs). Both the ABP and OTC-only groups initially will attend general health information sessions in-place of the AR program. Once the ABP+AR groups have completed their AR sessions, the ABP and the OTC-only groups will attend the AR programming sessions. By using this service-delivery model, it will be possible to analyze the effectiveness of the AR programming, separate from any benefits that might occur simply by meeting with others in a group setting.
Primary purpose: TREATMENT

Brief summary: This project will address quality of care issues associated with hearing loss in adults who have mild-to-moderate hearing loss and who have no access to hearing healthcare. Through the use of three different interventions involving over-the-counter hearing aids, it will lead to options that will increase access and affordability of hearing healthcare for adults with mild-to-moderate hearing loss.

Detailed description: The design for this study is outlined below according to each Aim.

Aim 1: To identify the effectiveness of over-the-counter hearing aids (OTC HAs) for decreasing hearing handicap and improving speech perception in adults with no access to hearing health care.

Aim 2: To implement an adult aural rehabilitation (AR) program for those without access to hearing health care to improve OTC HA benefit, promote OTC HA use and lead to increased quality of life (QOL).

Aim 1 will assess the effectiveness of OTC HAs for our participant population and Aim 2 will implement an AR program. With Aim 1, hearing loss will be assessed and an OTC HA will be provided. Prior to the hearing evaluation, participants will be randomly placed in one of three groups to assess the effectiveness of the AR program (Aim 2). The three groups include those who will receive the current best practices care from an audiologist (ABP), those who will receive the ABP plus an aural rehabilitation program (ABP+AR), and finally, those who will receive only an OTC HA without assistance from an audiologist for providing programming, maintenance or care information (OTC-only). Both the ABP and OTC-only groups initially will attend general health information sessions in-place of the AR program. Local health care providers who have training in general health areas such as nutrition, diabetes, obesity, and heart health to name a few, will provide the General Health and Wellness programming. Once the ABP+AR groups have completed their AR sessions, the ABP and the OTC-only groups will attend the AR programming sessions. This testing layout and schedule is provided in the table below.

Randomization will occur for each county visited and for the participants. Specifically, five counties will each receive a code and these codes will be randomized to determine when the study will take place in that area. All five regions will be included over a one-year period. Participant randomization will occur by generating three groups of random participant numbers and then assigning each participant to their designated group. Only the PI and the project manager will have access to the randomization lists. The PI will generate the randomization lists and the Project Manager will assign the participants accordingly to each group. The randomization lists will be kept on a password-protected computer and only accessible by the PI or Project Manager.

Audiologists will be blinded to the intervention condition for participants. Specifically, two audiologists (A1 and A2) will conduct the initial hearing evaluations. A2 will perform the OTC HA settings and orientations and a third audiologist (A3) will perform the follow-up speech perception testing in weeks 8 - 9. A second post-speech perception testing for all participants in week 14 will be conducted by A1.

The entire program will take place over a 14-week period for one county at a time. County 1 will begin at Week 1 and the remaining four regions will be stratified such that testing will begin at Week 9, 10 or 11 consecutively for each region. The stratification will be done to ensure that testing takes place in each area over a one-year period, and also, to avoid simultaneous testing at two sites. Finally, all participants who complete the study in years 1 and 2 will be invited back to complete speech perception testing and the AR surveys one year after they complete the study.
