Hearing Health Care Digital Therapeutics: Patient Satisfaction Evidence

A digital therapeutic is a software-based intervention for a disease and/or disorder and often includes a daily, interactive curriculum and exercises; online support from a professional versed in the treatment base; and an online support community, typically active as a social chat group. Recently, the Consumer Technology Association published revised standards for digital therapeutics (DTx) that stipulate that a DTx must be evidence based and founded in scientific evidence showing effectiveness and must be supported by evidence showing improved patient satisfaction and adherence to an intervention. The purpose of this study was to investigate whether a DTx could help older adults better adjust to their hearing loss and acclimate to new hearing aids.

Thirty older adults with mild or moderate hearing loss who had never used hearing aids participated. All hearing aids were fitted remotely. Participants used a hearing health care DTx (Amptify) for 4 weeks, either immediately following receipt of the hearing aids or 4 weeks after the fitting. A control condition was watching closed caption television. Participants completed a satisfaction questionnaire that queried about their impressions of the DTx, which had items that included both a rating scale of 1-7 and open-ended questions.

Ninety-six percent of the participants reported positive benefits, and one-half reported that the DTx helped them to adjust to their new hearing aids. They assigned a score of 5.8 to one of the questionnaire items that is similar to a Net Promoter Score Benefits, which included an enhanced ability to engage in conversation and increased listening confidence.

This investigation provides scientific evidence to support the use of a hearing health care DTx, paving the way for audiologists to be able to more easily and efficiently incorporate follow-up aural rehabilitation into their routine clinical services and to be able to provide services remotely.
