A WHO-backed feasibility study in South Africa tested whether trained community health workers, supported by mHealth tools, can deliver hearing aid services in underserved communities. The program achieved high satisfaction and 94% device retention at six months. The study’s operational design—five days of training for community workers with digital support—suggests a scalable model for countries where audiology staffing is limited. The results also indicate the service can maintain adherence without requiring specialist-heavy deployment for every step. For the biotech and medtech ecosystem, the work provides evidence that delivery infrastructure can be as important as device performance in real-world adoption. The headline takeaway is that task-shifting plus digital workflow support can extend hearing technology access while sustaining patient retention.
