Objective: Access to hearing care is challenging in low- and middle-income countries, where the burden of hearing loss is greatest. This study investigated a community-based hearing screening programme using smartphone testing by community care workers (CCWs) in vulnerable populations infected or affected by HIV. Experiences of CCWs were also surveyed. Design: The study comprised two phases. Phase one employed a cross-sectional research design to describe the community-based programme. Phase two was a survey design to describe CCW's knowledge and experiences. Study Sample: Fifteen trained CCWs administered hearing screenings on 511 participants during home-based visits using a validated smartphone application (hearScreen™) during phase one. Diagnostic follow-up assessments included evaluation using the smartphone test (hearTest™), otoscopy and tympanometry. Phase two surveyed the 15 CCW screening experiences. Results: Referral rates for adults and children were 5.0% and 4.2%, respectively. 75.0% of referred participants returned for follow-up diagnostic assessments, 33.3% were diagnosed with hearing loss and referred for further intervention. All 15 CCWs agreed that communities needed hearing services and only 6.6% did not want to continue providing hearing screening. Conclusion: Trained CCWs can decentralise hearing services to vulnerable communities using smartphone screening incorporating automated testing and measures of quality control.
