Changes in Home Care Clients' Sensory Impairment Status and Its Association With Functioning Over 18 Months: A Longitudinal Register-Based Study.

We investigated the changes in home care clients' vision and hearing over 18 months and examined the role of sensory impairments in maintaining their functioning. We used data from the Finnish Resident Assessment Instrument (RAI) database (n = 7013). Sensory impairment status was categorized by type (single or dual) and severity (mild or moderate/severe). The association between sensory impairment and functioning over 18 months was examined using binary logistic regression analysis with generalized estimating equations. Of 7013 home care clients, 48% had sensory impairment at baseline. Over 18 months, sensory impairment improved in 7% (n = 482) and worsened in 23% (n = 1605) of the clients. Sensory impairments were associated with impaired physical, cognitive, and psychosocial functioning at baseline. Especially moderate to severe dual impairment was associated with increased impairment in cognitive and physical functioning over time. Sensory impairments should be considered as an integral part of maintaining home care clients' overall health and well-being.
