Abstract

Purpose: To provide an example of the Medical Research Council’s (MRC’s) guidelines for evaluating complex healthcare interventions in the context of Smartphone-connected listening devices in adults with hearing loss.
Method: Twenty existing hearing aid users trialed one of the following Smartphone-connected listening devices: made-for- Smartphone hearing aids, a personal sound amplification product, and a Smartphone ‘hearing aid’ application used with either wireless or wired earphones. Following two-weeks of use in their everyday lives, participants completed self-report outcome measures.
Results: Relative to conventional hearing aids, self-reported use, benefit, and satisfaction were higher, and residual disability lower, for made-for-Smartphone hearing aids. The converse was found for the other Smartphone-connected listening devices trialed. Similarly, overall usability was judged to be ‘above average’ for the made-for-Smartphone hearing aids, but ‘below average’ for the remaining devices.
Conclusion: This developmental work, guided by the MRC’s framework, lays the foundation for feasibility and pilot studies, leading to high-quality research assessing the effectiveness of
Smartphone-connected listening devices. This future evidence is necessary to guide healthcare commissioners and policymakers when considering new service delivery models for adults living with hearing loss.
