Structured Support Improves OTC Hearing Aid Outcomes in Older Adults
Over-the-counter hearing aids may widen access to treatment for age-related hearing loss, but access alone does not guarantee benefit. In this multicenter randomized trial across ten community health centers in three Chinese cities, structured support consistently outperformed self-fitting among adults 50 years and older with untreated bilateral hearing loss.
The study enrolled 322 participants and assigned them in a 1:1:1 ratio to self-fitting, primary care physician support, or remote audiologist support. Outcome assessors and statisticians were masked, a design choice that strengthens confidence in the comparative results even in a pragmatic community setting. The primary endpoint was hearing-aid benefit on the Abbreviated Profile of Hearing Aid Benefit at 3 months, and both supported strategies produced larger gains than self-fitting alone.
Remote support delivered the largest adjusted mean difference, 12.20 points, with a 95% confidence interval of 7.18 to 17.22. Primary care physician support also improved outcomes, with an adjusted mean difference of 9.71 points and a 95% confidence interval of 4.74 to 14.67. The pattern is clinically meaningful because hearing aid use is not simply a device issue; success depends on fitting, expectation setting, troubleshooting, and adaptation during the first months of use. For older adults unfamiliar with amplification, even modest guidance can determine whether a device becomes part of daily life or ends up abandoned in a drawer.
One participant in the self-fitting group died of stroke.
No intervention-related serious adverse events occurred across the study arms, which matters because hearing-aid adoption often raises concerns about comfort, tolerability, and whether support services add procedural risk. Here, the safety profile was reassuring, while the efficacy signal favored structured care rather than unsupervised device use. In practical terms, the comparison was not between a medical procedure and no procedure; it was between two delivery models for a technology that already exists, but whose benefit depends on correct use.
Better Benefit, Better Use, Better Daily Function
The trial extended beyond a single questionnaire score. Hearing-related quality of life, satisfaction, speech recognition, and device use all favored the supported pathways, and those advantages persisted at 12 months. That durability is important because hearing rehabilitation is often judged too early or too narrowly. A user may tolerate a device for a few weeks, but persistent benefit requires sustained wear, ongoing adjustment, and enough perceived clarity to overcome the social and cognitive burden of hearing loss.
Age-related hearing loss carries consequences that reach far beyond decibel thresholds. Poor hearing can erode communication, reduce participation in family and community life, and make routine medical encounters less effective. In that context, structured support is more than a convenience feature. It likely reduces the friction created by fit problems, distorted sound, and confusion about how to adjust settings, which helps explain why remote and physician-supported care produced better speech recognition and greater device use than self-fitting alone.
The two supported models also differed in how they were delivered. Primary care physician support may lower the access barrier in community settings, while remote audiologist support introduces specialized expertise without requiring in-person specialty visits. Both approaches preserved the core advantage: the patient was not left alone to interpret the device’s performance. For hearing rehabilitation, that distinction can matter as much as the device itself.
Cost per Quality-Adjusted Life-Year Favors Both Supported Models
Economic findings reinforced the clinical data. At 12 months, incremental costs per quality-adjusted life-year gained were $167.16 for physician support and $361.17 for remote support. Those figures suggest that both strategies can be economically attractive, with physician support carrying the lower incremental cost in this comparison.
The mechanism behind the cost advantage is straightforward. When a lower-cost intervention improves adherence, satisfaction, and hearing-related function, the system avoids waste from underused devices and repeated remedial visits. Remote audiology support still adds value, particularly where specialist access is limited or community clinicians need backup, but the price of that expertise appears higher than physician-led support in this trial. For policy makers, the result frames support not as an optional add-on but as a service component that changes the value proposition of over-the-counter hearing rehabilitation.
What the Trial Means for Hearing Care Delivery
This trial places a clear marker in the debate over self-fitting hearing aids. Unassisted use did not match the outcomes achieved when older adults received either primary care physician support or remote audiologist support. The finding is especially relevant in settings where over-the-counter devices are intended to expand access quickly, because access without guidance may leave a substantial share of older users short of the benefit these devices can provide.
The Chinese Clinical Trial Registry entry identifies the study as ChiCTR2400086117, and the multicenter community design makes the findings more applicable to real-world care than a tightly controlled laboratory study would have been. Even so, the trial also raises pragmatic questions that future implementation work will need to answer: which patients can manage self-fitting successfully, which need hands-on support from the outset, and how health systems should balance specialist input with primary care delivery.
The answer on this evidence base is already visible in the outcome data. Structured support improved the effectiveness of over-the-counter hearing aids in older adults, and the gains held across patient-reported benefit, functional use, and economic value at one year.
