To estimate the prevalence and correlates of cognitive impairment (CI) among the elderly in a general hospital.
A cross-sectional study, including 200 Brazilian inpatients aged 60 years or over, using the Mini Mental State Examination to evaluate CI (dependent variable), and the Geriatric Depression Scale and the Katz and Lawton Index to evaluate basic (BADL) and instrumental activities of daily living (IADL).
56% were women, 29% were dependent for BADL and 77.5% for IADL. The prevalence of CI was 29% and, in the logistic regression, it remained associated with higher age (>74 years old), number of previous hospitalizations (>3) and dependency for BADL (being dependent raised the odds of being cognitively impaired).
It is essential to train the hospital staff to properly assist these patients, and to orient and support their caregivers.
评估综合医院老年患者认知障碍（CI）的患病率及其相关因素。
这是一项横断面研究，纳入了 200 名年龄在 60 岁及以上的巴西住院患者，使用简易精神状态检查（MMSE）评估 CI（因变量），使用老年抑郁量表（GDS）和 Katz 及 Lawton 指数评估基本日常生活活动能力（BADL）和工具性日常生活活动能力（IADL）。
女性占 56%，29%的患者依赖 BADL，77.5%依赖 IADL。CI 的患病率为 29%，在逻辑回归中，它仍然与较高的年龄（>74 岁）、既往住院次数（>3 次）和 BADL 依赖（依赖性增加认知障碍的可能性）相关。
培训医院工作人员以正确帮助这些患者，并为其护理人员提供指导和支持至关重要。
