Mental illness and brain disorders such as dementia are commonly encountered in patients with cognitive impairment in urology. In this cohort study, we assessed the prevalence and outcomes of inpatient admissions for stone disease in patients with cognitive impairment. Using the National Inpatient Sample database, we identified adults (>18 years) with stone disease between 2015 and 2019. The patients were dichotomized based on the presence or absence of cognitive impairment. The groups were compared for baseline differences in inpatient admissions and hospital complications. We evaluated the independent factors associated with urinary complications in the population using multivariate logistic regression. We identified 223,072 patients with stone disease. Patients with cognitive impairment were significantly (P<0.001) older (68 vs. 62 years), female (55.7% vs. 47.4%), had government-issued insurance (77.5% vs. 64.4%), and were discharged to a nursing facility (31.7% vs. 14.2%). Patients with cognitive impairment had significantly higher rates of urinary tract infection (29.7% vs. 21.5%, P<0.001), pneumonia (5.6% vs. 4.6%, P<0.001), systemic sepsis (4.3% vs. 3.8%, P<0.001), and acute renal failure (0.9% vs. 0.7%, P = 0.008). Female sex, low income, and cognitive impairment were all independently more likely to experience a urinary complication, with significant differences (P<0.001). Patients with cognitive impairment have a higher prevalence of stone disease and urinary complications associated with inpatient admissions than the rest of the population. Health care inequities among cognitively impaired patients should be a topic of further study.
