简要总结
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.
详细描述
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.

盲法说明
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. 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.

研究组 & 干预措施
Audiology Best Practices (ABP)
This comparison group of adults with hearing loss will receive a hearing evaluation and over-the-counter hearing aid fitting and orientation. The aural rehabilitation program will not be provided initially. These participants will complete pre- and post-questionnaires and speech perception testing.
干预措施: Hearing Evaluation (Behavioral)
Audiology Best Practices plus Aural Rehabilitation (ABP+AR)
This experimental group will receive a hearing evaluation, an over-the-counter hearing aid fitting and orientation, and four-weeks of an aural rehabilitation program conducted by specially-trained community health workers. Additionally, these adults will complete pre- and post-questionnaires and speech perception testing.

Over-the-Counter Only (OTC-Only)
This comparison group of adults with hearing loss will receive a hearing evaluation. They will be provided with over-the-counter hearing aids but the audiologist will not assist with fitting the aids or providing an orientation. This arm mimics what would happen when a consumer privately purchases over-the-counter hearing aids. They will complete pre- and post-questionnaires and speech perception testing.

结局指标
主要结局
Measuring Change in the Hearing Handicap Inventory for Elderly (HHIE) Outcomes
时间窗: A baseline outcome will be obtained prior to over-the-counter hearing aid fitting. Outcomes will be measured at weeks 4 to 7 of intervention, during week 14 of the intervention, and through study completion, or 1 assessment each year.
Twenty-five questions of the Hearing Handicap Inventory for Elderly (HHIE) measure emotional and social/situational consequences of hearing loss, including feelings of embarrassment, social isolation, and frustration. Scores range from 0 to 100 with higher scores indicative of poorer performance.
Measuring Change in International Outcome Inventory for Hearing Aids (IOI-HA) Outcomes
时间窗: A baseline outcome will be obtained prior to over-the-counter hearing aid fitting. Outcomes will be measured at weeks 4 to 7 of intervention, during week 14 of the intervention, and through study completion, or 1 assessment each year.
The International Outcome Inventory for Hearing Aids (IOI-HA) is an eight-item inventory that assesses daily use of over-the-counter hearing aid use, over-the-counter hearing aid benefit, and activity limitations to name a few. This is a scaled qualitative measure that assesses outcomes over time.
