Specialist clinical pathways in audiology services for adults living with coexisting hearing loss and dementia: a scoping review protocol.

Introduction: Both hearing loss and dementia are associated with ageing, and it is thought that many individuals living with dementia also live with hearing loss. Despite the large comorbidity between these two disorders, there remains a clear lack of established guidelines in audiological services for assessing and managing patients living with dementia. This scoping review aims to examine whether specialist clinical pathways exist in audiology services for people living with coexisting hearing loss and dementia and to describe the specific components and features of these pathways. This review will provide up-to-date information on clinical practice, identifying any gaps in care and in the literature to inform future research hypotheses and best practice guidelines.

Methods And Analysis: The methods are reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. The following electronic databases will be searched: CINAHL, EMBASE, MEDLINE, PsycINFO, PubMed, Scopus and Web of Science. The eligibility criteria are defined according to the domains of the SPIDER (Sample, Phenomenon of Interest, Design, Evaluation and Research type) search strategy tool. Primary research studies and select grey literature sources (eg, practice guidelines) will be eligible if published within the last 15 years. Studies eligible for inclusion must contain adults living with suspected or confirmed dementia, their carers, or clinicians within audiology services. Initial searches were performed on 31 January 2024 and will be updated before completion and submission of the review. Article quality will be appraised using an established tool: the Mixed Methods Appraisal Tool. The results will be synthesised and reported in line with reflexive thematic analysis guidelines.

Ethics And Dissemination: No ethical issues are foreseen as the review will collect secondary data only. Findings will be reported by peer-reviewed publication and by national and international academic conferences.
