Risk profiles for institutionalization in a cohort of elderly people with dementia or depression.

Seventy-five elderly persons with dementia or depression, served by a nursing outreach assessment and case management service in Belgium, were entered in a risk profiling study. Cluster analysis yielded three clusters, each presenting a different risk profile for institutionalization: (1) High Risk Profile, with subjects of moderately advanced age, highly dependent for activities of daily living (ADL), with severe cognitive impairment, poor communication skills, and behavioral problems; (2) Moderate Risk Profile, with subjects of advanced age, limited ADL-dependency, yet high care demands for Instrumental ADL (IADL), moderate to severe cognitive impairment, adequate communication competency, and some behavioral problems; and (3) Low Risk Profile, consisting of relatively young elderly, partially ADL and IADL-dependent, mild or no cognitive impairment, good communication abilities, and no particular behavioral problems.
