Abstract
To evaluate health care utilization in veterans with Alzheimer disease (AD) in the Veterans Affairs health system (VAHS).
This retrospective analysis identified veterans with AD using clinical notes extracted from the VAHS electronic health record from fiscal years 2010 to 2019.
The first note identifying AD was the index date. Health care utilization in veterans with AD and a 1:1 matched comparison group without AD was evaluated at 2 years preindex, 1 year preindex, 1 year post index, and 2 years post index.
From clinical notes, we identified 571,671 veterans with AD and 571,671 for the comparison group (overall: mean age, 74 years; 96% male; 75% White). In those with AD, outpatient visits per patient per year peaked 1 year post index at 67 and remained elevated 2 years post index at 57; without AD, the rate was approximately 19 at all time points. Hospitalization rates peaked at 1 year post index with AD but were lower and generally stable without AD. Nursing home utilization was relatively low overall. Veterans meeting the 2-code criteria (n = 56,305), defined as having 2 diagnostic codes for AD recorded at least 30 days apart, had consistently higher utilization than veterans without AD (especially post index).
Veterans with AD have higher health care utilization than veterans without AD, especially around the time of AD diagnosis.
