Medicare expenditures associated with Alzheimer disease

This study uses 4 years of data from the Medicare Current Beneficiary Survey to compare the use of Medicare covered services for persons who report having a diagnosis or dementia ol Alzheimer disease with those who do not, adjusting for the prevalence of comorbidities and functional limitations. Although overall rates of Medicare spending are higher for demented persons, when other factors such as functional status are included in the predictive model, there is no consistent relation between the presence of dementia and higher Medicare spending. In some years, dementia was associated with higher adjusted expenditures for community living persons, whereas nursing home residents with Alzheimer disease have lower Medicare expenditures.
