Description
Summary:Objectives To assess differences in resource use and cost between older adults with and without mild cognitive impairment (MCI) over time. Design Multicenter, longitudinal study. Setting Sixty‐eight Alzheimer's Disease Cooperative Study (ADCS) sites in the United States. Participants Two hundred fifty‐nine individuals diagnosed with MCI and 107 cognitively normal elderly adults followed annually for 3 years. Measurements The Resource Use Instrument (RUI) was used to capture medical and nonmedical care use. Generalized linear latent and mixed models were used to estimate differences in resource use and costs in older adults with and without MCI after controlling for clinical and demographic characteristics. Results At baseline, average annual direct medical cost per person was substantially higher for participants with MCI ($6,499) than for those without ($2,969) P
