HMN 2025: How Audiologist-fitted listening can outperform over-the-counter ones

Over-the-counter (OTC) listening to aids (HAs), during which audiologists present restricted providers, are efficient, however don’t obtain the identical outcomes as HAs fitted by audiologists (AUD service model), in line with a review published on-line May 15 in JAMA Otolaryngology-Head and Neck Surgery.

Yu-Hsiang Wu, M.D., Ph.D., from the University of Iowa in Iowa City, and colleagues carried out a randomized medical trial on the University of Iowa and Vanderbilt University Medical Center involving 245 adults aged older than 55 years with mild-to-moderate listening to loss and no earlier HA {experience}.

Participants had been randomly assigned to one in every of six teams representing factorial mixture of three service models and two know-how ranges. The service models had been AUD, during which prescription HAs had been fitted by audiologists following greatest practices; OTC+, during which audiologists offered restricted providers for OTC HAs; and independently used OTC HAs. Throughout the trial, two know-how ranges of prescription HAs had been used: a high-end HA with superior options and low-end HA.

The researchers discovered that the postintervention ecological momentary evaluation (EMA)-administered Glasgow Hearing Aid Benefit Profile (GHABP) was considerably increased for AUD than for OTC+ and OTC by 0.33 and 0.32 factors, respectively; after controlling for preintervention scores, the distinction between OTC+ and OTC was not important. EMA-GHABP world scores had been near 4 factors for OTC+ and OTC, indicating constructive outcomes. No important impact of know-how stage or interplay between service model and know-how stage was seen.

“This randomized medical trial discovered that the OTC+ and OTC service models had been efficient however didn’t obtain the identical outcomes because the AUD service model,” the authors write.
