Abstract
BackgroundCognitive impairment is common in older adults and negatively affects hearing aid use. Audiologists hold the opportunity to identify signs of undiagnosed cognitive impairment and tailor care to optimise hearing aid use.ObjectiveTo assess the feasibility of introducing a brief cognitive assessment in hearing aid appointments for older adults.MethodsProspective feasibility cohort study incorporating quantitative and observational data. Participants were patients aged ≥65 years, new or existing hearing aid users, attending an NHS community hospital hearing aid clinic. Clinical audiologists were trained to conduct the Ascertain Dementia 8 (AD8) and visually-adapted shortened version of the Montreal Cognitive Assessment (mini-MoCA). A research audiologist took informed consent, observed appointments recording outcomes and followed up participants at 3 months. Feasibility was assessed using the following outcome measures: practicality of implementation in a clinical setting and resource requirements; acceptability in terms of recruitment/completion rates; onward care; experiences through standardised intensity scoring of observed emotions and analysis of free-text observations of participant reactions, participants' comments and informal conversations with clinical audiologists.ResultsTwenty patients were recruited, average age 78.6 years, 14 (70%) attended alone. All completed cognitive assessment, average duration was 14 minutes. AD8 and mini-MoCA average scores were 2.4 (range: 0-7) and 12.8 (range: 8-15), respectively. Ten (50%) participants had AD8 scores and one (5%) a Mini-MoCA score indicating potential cognitive impairment. Four of those (40%) contacted their GP, three were referred for further cognitive evaluation, one was diagnosed with dementia, two were awaiting appointments.ConclusionsIntroducing cognitive assessment in hearing aid clinics seems feasible and may provide an opportunity for identifying cognitive impairment in older adults, though further research is needed to establish its clinical utility and impact on care pathways. There are considerable resource implications, highlighting the importance of involving professional organisations, healthcare funders and policy makers early in this discussion.
