In patients with dementia, psychosis more than doubled the risk of death and nearly 2.5x the risk of the need for long-term institutionalized care than patients without psychosis.
Why this matters
The projected growth of dementia is expected to increase with an ageing world population and understanding its clinical course and potential long-term outcomes is a major research priority.
No estimates of dementia-related psychosis (DRP) incidence derived from large administrative databases have been reported, nor have the potential implications (e.g. long-term institutionalized care and death) been quantified.
The results from this study provide important information for patients, healthcare professionals, payers and the public health community.
