To determine the prevalence of delirium and other alterations in mental status in older adults in the emergency department setting.
Prospective, cross-sectional study.
Private, nonprofit, academic medical center in a densely populated urban area.
One hundred eighty-eight adults 70 years or older who presented to the ED.
None.
Delirium and other alterations in mental status were present in 39.9% of the patients studied; 24% of these patients had delirium. Age and severity of illness were positively correlated with alteration in mental status. Patients with alterations in mental status were more likely to be admitted to an inpatient unit. Among those admitted from home, alterations in mental status in the ED were associated with a higher likelihood of institutionalization at discharge.
Alterations in mental status are prevalent in ED patients. Older adults with alterations in mental status, particularly alterations in consciousness and delirium, are at high risk for admission to an inpatient unit and institutionalization after discharge. Standardized mental status testing identified high-risk older adults in the ED.
确定急诊室环境中老年人谵妄及其他精神状态改变的患病率。
前瞻性横断面研究。
人口密集市区的私立非营利性学术医疗中心。
188名70岁及以上到急诊科就诊的成年人。
无。
在研究的患者中，39.9%存在谵妄及其他精神状态改变；其中24%的患者有谵妄。年龄和疾病严重程度与精神状态改变呈正相关。精神状态改变的患者更有可能被收入住院病房。在家中就诊后入院的患者中，急诊科的精神状态改变与出院后入住机构的可能性较高有关。
精神状态改变在急诊患者中很普遍。精神状态改变的老年人，尤其是意识改变和谵妄患者，住院和出院后入住机构的风险很高。标准化的精神状态测试可识别急诊室中的高危老年人。
