Dementia Nursing Home Entry, Mortality

Background: Dementia is highly prevalent, but there are little consistent data about prognosis, with wide ranges of survival expectations. The most recent systematic reviews included studies from before 2012 and could not quantify the effects of factors, such as age and cause of dementia.

Objective: To summarize available evidence on time to nursing home admission and death among people with dementia, and to explore prognostic indicators. Design: Systematic review and meta-analysis.
