People with all-cause dementia have high rates of suboptimal hospice use, but little is known about hospice use patterns in Lewy body disease, which includes both Parkinson disease (PD) and dementia with Lewy bodies (DLB).<\/jats:p><\/jats:sec>Objective<\/jats:title>To compare patient characteristics, hospice agency characteristics, and patterns of use for beneficiaries with PD and DLB vs Alzheimer disease (AD).<\/jats:p><\/jats:sec>Design, Setting, and Participants<\/jats:title>A retrospective cohort study including a 100% sample of national 2010-2020 calendar year Medicare data on hospice enrollees was performed.

People with PD were more likely to experience a long stay (odds ratio [OR], 1.15; 95% CI, 1.13-1.16) compared with AD, whereas the odds for those with DLB were not increased. However, people with either PD or DLB were less likely to be disenrolled for extended prognosis compared with AD (OR for DLB, 0.82; 95% CI, 0.79-0.85; OR for PD, 0.86; 95% CI, 0.85-0.88).
