Alzheimer’s disease and related dementias increase costs of comorbidities in managed Medicare

Abstract

In this study, prevalence rates for ADRD mirrored population estimates. Costs for patients with ADRD in this Medicare MCO varied considerably by comorbid condition and were substantially higher for patients with both AD and comorbid diseases commonly targeted for disease management, indicating that AD increases costs through effects on the management of comorbid illnesses. These findings indicate that better treatment and care management of AD could reduce the costs of comorbid illnesses commonly experienced by the frail elderly.
