Systematic Review of Factors Associated With Hearing Aid Use in People Living in the Community With Dementia and Age-Related Hearing Loss

ObjectivesTo investigate factors that influence hearing aid use according to the Theoretical Domains Framework (TDF). The TDF is a behavioral science framework that aids understanding of factors that influence behavior.DesignSystematic review.Setting and ParticipantsPeople living in the community with dementia and age-related hearing loss who have air conduction hearing aids.MethodsSystematic literature review following PRISMA guidelines. We searched for studies in 9 databases, including Ovid MEDLINE, Scopus, and OpenGrey. We undertook an interpretive data synthesis by mapping findings onto the TDF. We assessed confidence in the findings according to the GRADE-CERQual approach.ResultsTwelve studies (6 quantitative, 3 qualitative, and 3 mixed methods) were included in the review. The majority of these were rated low-moderate quality. We identified 27 component constructs (facilitators, barriers, or noncorrelates of hearing aid use) nested within the 14 domains of the TDF framework. Our GRADE-CERQual confidence rating was high for 5 findings. These suggest that hearing aid use for people living in the community with dementia and hearing loss is influenced by (1) degree of hearing aid handling proficiency, (2) positive experiential consequences, (3) degree of hearing aid comfort or fit, (4) person-environment interactions, and (5) social reinforcement.Conclusions and ImplicationsHearing aid interventions should adopt a multifaceted approach that optimizes the capabilities of people with dementia to handle and use hearing aids; addresses or capitalizes on their motivation; and ensures their primary support network is supportive and encouraging of hearing aid use. The findings also emphasize the need for further high-quality research that investigates optimal hearing aid use, influencing factors, and interventions that support hearing aid use.     

Hearing aid use in nursing homes. Part 1: Prevalence rates of hearing impairment and hearing aid use

Although hearing impairment is among the most common chronic ailments of older persons, the problem is even greater among those in nursing homes. It is estimated that 70% to 90% of elderly residents in long-term care facilities have some degree of hearing impairment. Despite this high prevalence, significant underuse of hearing aids or other assistive devices exists, especially among those with dementia. OBJECTIVES: The current study assessed rates of hearing impairment and hearing aid use among residents in a large, mid-Atlantic nursing home. SETTING AND DESIGN: In a cross-sectional survey, interviews were conducted at a large, mid-Atlantic nonprofit nursing home. PARTICIPANTS: Reports were obtained from 279 resident-caregiver dyads, as well as from the Minimum Data Set (MDS) and research assistants performing the structured interviews. MEASUREMENTS: Measures included the MDS and the Barriers to Hearing Aid Use Questionnaire, which was developed for this study. RESULTS: Results show an inconsistency in reports of both hearing impairment and hearing aid use by multiple sources, as well as the underuse of hearing aids. These inconsistencies suggest that gross hearing impairment is undetected in clinical practice in over half of the residents. CONCLUSION: The findings highlight the need for regular hearing assessments in the nursing home population. They also suggest the need for evaluation of institutional-level policies regarding screening and hearing aid management, as well as the need for further information regarding potential barriers to effective hearing aid use. These issues are addressed in part 2 of this study following this report.
