The impact of dementia-related psychosis on the US healthcare system


  • 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.
