Abstract Background Urinary tract infections (UTIs) are common complications among hospitalized patients with Parkinson's disease (PD) and are associated with delirium and prolonged hospitalization. Objectives To determine the prevalence of UTI, identify modifiable risk factors, and evaluate associated outcomes among hospitalized patients with PD. Methods We conducted a retrospective cohort study using the PINC‐AI Healthcare Database including PD‐related hospitalizations from 2019 to 2023. UTIs diagnosed on admission or during hospitalization were identified, and multivariable analyses were performed. Results Among more than 321,000 PD hospitalizations, 18.9% were associated with UTI. Emergent admission, inter‐facility transfer, dementia, and indwelling urinary catheter use were independently associated with UTI, whereas male sex was protective. UTI was associated with prolonged length of stay and delirium. Conclusions UTIs are frequent among hospitalized patients with PD and are associated with several modifiable risk factors. These findings may inform PD‐specific inpatient strategies for UTI prevention and risk stratification.
