Dementia, which is prevalent in geriatric THA recipients, is correlated with several adverse outcomes.

The Wilcoxon rank test (for continuous data) and Chi\u2012square test (for categorical data) were used to assess demographic characteristics, comorbidities, LOS, total hospital costs, and in-hospital mortality; logistic regression analysis was employed to determine the influence of dementia on adverse outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>376\u00a0323 elective geriatric THA patient samples from the NIS database were included, with an overall dementia prevalence of 2.05%.
