Meta Analysis
Delirium in elderly patients and the risk of postdischarge mortality, institutionalization, and dementia: a meta-analysis.
Delirium is a common and serious complication in elderly patients. Evidence suggests that delirium is associated with long-term poor outcome but delirium often occurs in individuals with more severe underlying disease. ⋯ This meta-analysis provides evidence that delirium in elderly patients is associated with poor outcome independent of important confounders, such as age, sex, comorbid illness or illness severity, and baseline dementia.
