Community-based assessment and rehabilitation of hearing loss: A scoping review

Although the World Health Organization (WHO) recommends the use of a Community-Based Rehabilitation (CBR) model, little is known about how CBR has been applied in the hearing healthcare setting. The purpose of this scoping review was to identify and describe studies on Community-Based Hearing Rehabilitation (CBHR) programs within the applied context. The review was conducted in September 2020 with updated searches in November 2021 according to the Joanna Briggs Institute (JBI) methodology and reported using the guidelines and checklist for Preferred Reporting Items for Systematic Reviews and Meta Analyses-Extension for Scoping Reviews (PRISMA-ScR). Fifty-nine peer-reviewed research articles were included in the review. A narrative synthesis was conducted to map out the types of CBHR programs. Studies were classified into audiological themes: awareness, screening and assessment of hearing in newborn/infants, children and adults, training of community health workers, rehabilitation, cost-effectiveness and describing the service delivery models. Further categorisation was made based on CBR aspect matrices for each study. Most of the studies come from high-income countries in North America and Europe. CBHR studies predominantly focused on creating awareness, training and hearing screenings and/or assessments in communities and evaluating effectiveness in providing knowledge and access to hearing health services in rural or underserved communities. Further work is needed to examine the outcomes and effectiveness of CBHR using controlled studies. Moreover, more work is needed in low- and middle-income countries where the application of CBHR is critical for increased access and affordability.
