Chronic conditions and multimorbidity associated with institutionalization among Finnish community-dwelling older people: an 18-year population-based follow-up study

Abstract

<p>Key summary points</p><p>Aim The aim of the study is to assess the association of chronic conditions and multimorbidity with institutionalization in older people.</p><p>Findings Having dementia, mood or neurological disorder and/or five or more chronic conditions were associated with a higher risk of institutionalization.</p><p>Message These risk factors should be recognized in primary care when providing and targeting care and support for home-dwelling older people.</p><p>Purpose</p><p>The ageing population is increasingly multimorbid. This challenges health care and elderly services as multimorbidity is associated with institutionalization. Especially dementia increases with age and is the main risk factor for institutionalization. The aim of this study was to assess the association of chronic conditions and multimorbidity with institutionalization in home-dwelling older people, with and without dementia.</p><p>Methods</p><p>In this prospective study with 18-year follow-up, the data on participants' chronic conditions were gathered at the baseline examination, and of conditions acquired during the follow-up period from the municipality's electronic patient record system and national registers. Only participants institutionalized or deceased by the end of the follow-up period were included in this study. Different cut-off-points for multimorbidity were analyzed. Cox regression model was used in the analyses. Death was used as a competing factor.</p><p>Results</p><p>The mean age of the participants (n = 820) was 74.7 years (64.0-97.0). During the follow-up, 328 (40%) were institutionalized. Dementia, mood disorders, neurological disorders, and multimorbidity defined as five or more chronic conditions were associated with a higher risk of institutionalization in all the participants. In people without dementia, mood disorders and neurological disorders increased the risk of institutionalization.</p><p>Conclusion</p><p>Having dementia, mood or neurological disorder and/or five or more chronic conditions were associated with a higher risk of institutionalization. These risk factors should be recognized when providing and targeting care and support for older people still living at home.</p>
