Prevalence of cognitive impairment in Chinese older inpatients and its relationship with 1-year adverse health outcomes: A multicenter cohort study

Previous studies on the relationship between cognitive impairment and adverse outcomes among geriatric inpatients are not representative of older inpatients in China because of insufficient sample sizes or singlecenter study designs. The purpose of our study was to examine the prevalence of cognitive impairment and the relationship between cognitive impairment and 1-year adverse health outcomes in older inpatients.
