OBJECTIVES: To determine whether dementia increases medical expenditures, the probability of hospitalization, and potentially preventable hospitalization, controlling for variables including age and comorbidity.DESIGN: Cross-sectional analysis of 1 year of claims data comparing usage by patients with claims for dementia with usage by those without dementia.SETTING: A nationally representative 5% random sample of Medicare beneficiaries in 1999.PARTICIPANTS: Medicare beneficiaries aged 65 and older with fee-for-service Medicare Parts A and B coverage for 1999 (N=1,238,895; dementia patients n=103,512).MEASUREMENTS: Per capita expenditures, rate of all-cause hospitalization, rate of preventable hospitalization as defined using ambulatory-care sensitive condition (ACSC) admissions, and dementia identified using International Classification of Diseases, 9th Edition, codes 290, 294, and 331.RESULTS: Prevalence of dementia was 8.3%. In a model of expenditures in those who survived the year adjusting for age, sex, race, and comorbidity, dementia was associated with an incremental cost of $6,927, or 3.3 times greater total expenditures than in nondementia patients (P
