This article discusses whether geriatric consultation is better than usual care for reducing delirium in patients with delirium superimposed on dementia. Studies were selected if they included data on patients with delirium superimposed on dementia, had a validated operational definition or measure of dementia and delirium, reported actual data on patients with delirium and dementia, and reported primary data. One randomized controlled trial comparing a geriatric consultation intervention with usual care showed that patients in the consultation group had greater reduction in delirium than did those in the usual care group. In a prospective observational study where more patients had delirium with dementia than delirium alone, 12-month mortality was higher in patients with delirium without dementia. Delirium has predicted 12-month mortality independent of dementia status and was associated with a 2-fold increase in mortality during the 12-month follow-up.
