  • Research summary

    Adults with CF regularly receive anti-infective therapy that can result in impaired hearing. Recent studies have identified that up to 50% of adults with CF have hearing loss with resulting significant impact on quality of life. At present, however, there is no national recommendation to screen for hearing loss within adult CF.

    Formal hearing tests are costly, require specialist staff and equipment and require further outpatient visits resulting in significant impact on health, social and financial resource. A novel interactive Apple-iPad app-based audiometer is now available and CE marked (Shoebox MD, Clearwater Medical) that can be used by non-audiologists to test hearing in a standard outpatient setting. Furthermore a novel interactive web-based hearing app has recently been developed (3D Tune-In). This technology has not been used to date in an adult cohort such as people with cystic fibrosis.

    We propose to analyse over a 12 month period at two adult cystic fibrosis centres in London whether outpatient tablet based audiometry testing and web-based hearing apps are able to accurately screen for ototoxicity in adults with CF, and whether these methods of screening are acceptable. We will determine whether this technology is as reliable as formal hearing tests and better than standard questionnaire-based screening. We will examine whether this approach can be used within the existing CF outpatient clinic by non-specialist staff to enable streamlining of care. Through this project we will also determine the incidence and significance of certain genetic mutations in predisposition to hearing loss in CF to inform further studies.

    The results of this study will aim to streamline audiometry screening to improve detection rates, reduce cost of healthcare, enable equity in service delivery, and minimize disruption to the patient’s social and work-life using smart technology. The study is being sponsored by the NHS Darzi fellowship scheme and UK CF trust.
