“…Fourth, we only conducted electronic searches and did not handsearch journals. It is possible that we may have missed articles that were not properly indexed on the electronic databases, or where indexing was delayed–for example, a potentially relevant review on the prevalence of DSI [ 118 ] published in January 2022 was not indexed by the time of our searches in April 2022. However, the findings are consistent with the findings of our scoping review–that prevalence increases by age, and the findings across studies were often not comparable.…”

Hearing and vision impairments are common globally. They are often considered separately in research, and in planning and delivering services. However, they can occur concurrently, termed dual sensory impairment (DSI). The prevalence and impact of hearing and vision impairment have been well-examined, but there has been much less consideration of DSI. The aim of this scoping review was to determine the nature and extent of the evidence on prevalence and impact of DSI. Three databases were searched: MEDLINE, Embase and Global Health (April 2022). We included primary studies and systematic reviews reporting the prevalence or impact of DSI. No limits were placed on age, publication dates, or country. Only studies where the full text was available in English were included. Two reviewers independently screened titles, abstract, full texts. Data were charted by two reviewers independently using a pre-piloted form. The review identified 183 reports of 153 unique primary studies and 14 review articles. Most evidence came from high-income countries (86% of reports). Prevalence varied across reports, as did age groups of participants and definitions used. The prevalence of DSI increased with age. Impact was examined across three broad groups of outcomes—psychosocial, participation, and physical health. There was a strong trend towards poorer outcomes for people with DSI across all categories compared to people with one or neither impairment, including activities of daily living (worse for people with DSI in 78% of reports) and depression (68%). This scoping review highlights that DSI is a relatively common condition with substantial impact, particularly among older adults. There is a gap in evidence from low and middle-income countries. There is a pressing need for a consensus position on the definition(s) of DSI and standardisation of reporting age groups to enable reliable estimates to be ascertained and compared and responsive services developed.

“…Our review is a first attempt to synthesize the evidence on this topic to directly inform clinical practice, examining scientific articles from seven research databases and three clinical trial registries since their inception. Even though the number of older adults with DSI is projected to increase with age worldwide ( Minhas et al, 2022 ), the most intriguing finding was that there are only a few tools and strategies that have been developed, tested, or used to ensure that older adults with DSI receive proper screening, diagnosis, clinical or lab assessments, and interventions. Another important point to consider is whether these existing tools and strategies are even known among clinical care providers.…”

“…The prevalence of DSI increases with advancing age and is projected to continue to rise over the next decade, particularly in high- and middle-income countries ( Guthrie et al, 2016 ; Minhas et al, 2022 ). For older adults above 80 years, the prevalence of DSI was reported to be 11.3% in the United States ( Swenor et al, 2013 ) and 26.8% in Australia ( Schneider et al, 2011 ).…”

Background and Objectives A global report estimates up to 2% of the world population experience concurrent hearing and vision impairment (dual sensory impairment/DSI). Older adults with DSI are often frequent users of healthcare, yet the evidence is limited to inform care delivery for this population. This systematic review aimed to synthesize evidence on tools and strategies for screening, assessment, and interventions that promote a continuum of care for older adults with DSI. Research Design and Methods The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews. Electronic databases (CINAHL, Embase, MEDLINE, PsycINFO, Cochrane Library, Global Health, and Web of Science) and clinical trial registries (ISRCTN Registry, WHO ICTRP, and ClinicalTrials.gov) were searched. The quality appraisal was performed using the Mixed Methods Appraisal Tool. Results Of 4775 identified references, 28 records were selected. The review identified seven tools and seven strategies for DSI-specific screening, assessments and/or interventions. Some of the most promising tools were the interRAI Community Health Assessment (CHA) with deafblind supplement, adapted Montreal Cognitive Assessment (MoCA) and Severe Dual Sensory Loss (SDSL) screening tool. Useful strategies included the use of alternative forms of communication, assistive devices or technology, education and training for service providers, and training of older adults on the use and maintenance of assistive aids/technology. However, quality appraisal indicated a need for more robust evidence to inform clinical practice. Discussion and Implications Reviewed evidence pinpointed the need for training for healthcare providers on DSI-specific challenges and supports and the use of integrated multidisciplinary care for older adults. Future studies need to explore the development and evaluation of tools and interventions to improve the continuum of care for this group.

“…Noviji podaci koji se tiču učestalosti na globalnom nivou značajno su alarmantniji i upozoravaju da od 0.2 do 2% populacije živi sa nekim oblikom slepogluvoće, pri čemu se očekuje da je stvarni broj mnogo veći, jer ovaj vid invalidnosti nije dovoljno proučen i često se pogrešno dijagnostikuje (Paramasivam et al, 2021). Na osnovu analize 19 radova objavljenih od 2000. do 2020. godine, u kojima su diskutovani podaci o prevalenciji slepogluvoće u 18 zemalja, zaključeno je da postoje različiti rasponi učestalosti, povezani sa starošću i tipom slepogluvoće, kao i da se prevalencija dvostrukog senzornog oštećenja povećava sa godinama (Minhas et al, 2022).…”

Introduction. Deaf-blindness is a dual sensory impairment and adversely affects different areas of a person's functioning. Thus, there is a need for an individualized approach to education and rehabilitation, as well as specific services that facilitate learning, participation, and social inclusion. The study of this phenomenon is accompanied by challenges arising from the lack of consensus on the definition of deaf-blindness, the heterogeneity of the population, and the lack of reliable tests and tools for assessment. Furthermore, the use of traditional procedures that are often based only on the determination of sensory functioning, as well as insufficiently efficient and untested working methods, hinder the development of communication with a person who is deafblind. Objectives. The aim of this paper was to analyze the specific communication methods of people with deaf-blindness and, in particular, to analyze and describe tactile sign language. Methods. The service of the Consortium of Libraries of Serbia for unified acquisition - KOBSON and Google Scholar Advanced Search were used for the search and analysis of relevant studies. Searches were performed using the following services/ aggregators: Ebsco host, ScienceDirect, and Wiley Inter Science. Results. Communication of people with deaf-blindness can occur through a variety of modalities: speech, sign language, finger alphabet/alphabet, manual alphabet/manual alphabet, Lorm's alphabet, palm writing, Tadoma method, written language, Braille, enlarged print, tactile sign language. In recent studies, authors emphasize the need to develop a unique tactile sign language as a natural language of persons who are deafblind from birth.
