Prevalence of Hearing, Vision and Cognitive Impairment and Impact in Older Adults in Home Care: A Study Protocol

Hearing, vision and cognitive impairments are common yet frequently underrecognized among older adults. Although these impairments affect quality of life, functional independence and psychological well-being, there are no published data on the prevalence and consequences of these impairments in relation to Australian home care populations. This protocol outlines a cross-sectional investigation into the prevalence of hearing, vision and cognitive impairments and their associations with quality of life, functional ability and psychosocial well-being among older Australians receiving home care services.

A total of 369 participants aged 65 years and older will be recruited from home care services across Australia. Standardized assessment tools will be used to assess hearing, vision and cognitive function, quality of life, daily living activities, mental health and social participation. Multi-variable regression models will explore the impact of sensory and cognitive impairments on health and well-being outcomes.

With ageing populations, it is increasingly important to support older people to live independently in their own homes rather than needing to move into residential aged care. This study will facilitate understanding of the prevalence and impact of sensory and cognitive impairments among the older Australian home care population. Findings may inform strategies to support health ageing in place, including service planning, care coordination and workforce training.

Older adults receiving home care services and individuals with lived experience of sensory and cognitive impairments contributed to the study design. A Patient and Public Involvement advisory group and a stakeholder steering group will guide study implementation.
