Development of a National Ménière's Disease Registry: A Feasibility Study.

Ménière's disease is a disabling condition causing vertigo and hearing loss yet remains incompletely understood. Registry studies have the potential to answer important questions about phenotypes and natural history of clinical conditions. The aim of this study was to explore the feasibility of a patient-centered national Ménière's disease registry. This was an observational study carried out at 4 state-funded hospitals and 4 independent clinics, within 3 distinct urban and rural regions within the UK. Adults with Ménière's disease were eligible to participate. A range of patient reported data, questionnaire data and clinical data (audiometric, radiological, and specialist balance testing data) was inputted into a bespoke database. The study recruited 411 participants. The majority of participants chose online recruitment (73%) and 27% chose via paper-based methods for participation. A small majority (57%) of participants were female. 96% of participants were of white ethnicity. Data completeness from online or postal data collection was similar. Around 20% of participants had audiological evidence of bilateral Ménière's disease. This feasibility study has successfully piloted methods for recruitment of hundreds of participants diagnosed with Ménière's disease. Participants actively contributed their data to a robust and extensive data collection platform. The positive outcomes from this initial feasibility study are anticipated to serve as a foundation for the future expansion of the registry. This expansion holds the potential to address a broad spectrum of request, encompassing all aspects of the nature of Ménière's disease.
