Factors Affecting the Adoption and Use of Hearing Aids among Older Adults: A Systematic Review

The most effective modality for presbycusis is using hearing aids. However, the rate of adoption and use of hearing aids among the elderly is not in line with the expectations. This review investigates the current evidence to identify factors affecting the adoption and use of hearing aids among the elderly with hearing loss. This is a systematic review whose sample includes English articles published in peer-reviewed journals from January 2015 to October 2020. The search was conducted in PubMed, Web of Science, ProQuest, and Scopus electronic databases. Study selection, data extraction, and quality assessments were performed by two independent reviewers. In the 22 studies included in this review, a number of factors, including demographic status (economic status and level of education), auditory factors (hearing loss severity, presence of tinnitus, and the sound quality of hearing aids), attitudinal and psychosocial factors (self-perceived hearing problems, perceived self-efficacy, perceived benefit, support from significant others, and extrovert and ambivert personality types) were identified as variables potentially impacting the adoption and use of hearing aids. The results show that demographic, attitudinal, and psychosocial factors, as well as auditory factors, play an influential role in the adoption and use rate of hearing aids among older populations suffering from hearing loss. Therefore, it is necessary to consider these factors in order to formulate hearing healthcare policies and adopt targeted and appropriate interventions in the process of prescribing, adjusting, and evaluating hearing aids. The protocol of this systematic review was published in the International prospective register of systematic reviews (PROSPERO) with registration number: CRD42021227684 (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021227684)
