Delirium in a patient with preexisting dementia is a common problem that may have serious complications and poor prognostic implications. The purpose of this paper was to conduct a systematic review of the medical literature on delirium superimposed on dementia, specifically to review studies on prevalence, associated features, outcomes, and management. Areas of controversy and gaps in our knowledge of this problem are highlighted. ⋯ The prevalence of delirium superimposed on dementia ranged from 22% to 89% of hospitalized and community populations aged 65 and older with dementia. To date, only one reported study systematically identified associated factors and interventions for delirium superimposed on dementia, but several studies examining outcomes have found that adverse events are associated with delirium in persons with dementia, including accelerated and long-term cognitive and functional decline, need for institutionalization, rehospitalization, and increased mortality. This paper highlights the dearth of research on delirium superimposed on dementia and stresses the importance of early recognition and prevention of delirium in persons with dementia.

To estimate the billed charges generated for the university hospital (UH) by patients seen in a UH outpatient senior clinic over a 6-month period. To estimate the average billed charges per geriatric patient generated for the UH over the same 6-month period. ⋯ This study provides a reasonable estimate of the substantial multiplier, or "flow-through," effect of a senior clinic on its parent medical center. Although senior clinics may be a cost center when viewed in isolation, these clinics are actually revenue generators when viewed from the perspective of the entire health system.
