Hearing help-seeking, hearing device uptake and hearing health outcomes in individuals with subclinical hearing loss: a systematic review

ObjectiveThis systematic review aims to examine the current literature on help-seeking, hearing device uptake, and hearing health outcomes in individuals with subclinical hearing loss.DesignSystematic review.Study SampleSearches of three databases (CINAHL, MEDLINE (PubMed), and Scopus) yielded nine studies meeting the inclusion criteria. The quality of the included studies was determined using the National Institute of Health quality assessment tool. The studies' level of evidence was determined according to the Centre for Evidence-Based Medicine.ResultsAll included studies involved adult participants. Three studies examined help-seeking. Self-reported difficulty, poor speech-in-noise performance, and emotional responses to the hearing difficulty were identified as factors influencing help-seeking. Six studies examined the use of hearing devices as an intervention, including hearing aids (n = 4), hearables (n = 1), and FM systems (n = 1). Using hearing devices improved self-perceived hearing difficulty, speech-in-noise understanding, and motivation to address hearing difficulties. No studies focused on hearing device uptake. The quality assessment indicated limited methodological rigour across the studies, with varying levels of evidence.ConclusionsCurrent evidence supports the use of hearing devices as an intervention for individuals with subclinical hearing loss. However, more research is essential, particularly focusing on help-seeking, diagnosis, treatment, and long-term outcomes using well-controlled study designs.
