我们评估了325名来自指定社区或长期护理机构的教学医院的老年患者谵妄的发生和持续时间。在研究参与者中，34人（10.5%）在初始评估时患有第三版《精神障碍诊断与统计手册》定义的谵妄；其余91例（31.3%）出现新发谵妄。另外110名患者也经历了谵妄的个别症状，但不符合全部标准。在社区样本中，先前存在的认知障碍和高龄与突发谵妄的风险增加有关，而在机构样本中则没有。谵妄与死亡风险增加无关，但在社区居住的老年人中，谵妄与住院时间延长和机构安置风险增加有关。只有5名患者（4%）在出院前所有谵妄新症状得到缓解，出院后3个月和6个月所有新症状得到缓解的分别只有20.8%和17.7%。这些数据表明，谵妄是一种常见的疾病，可能比目前认为的要短暂得多，而且该综合征的不完全表现可能很常见。
We evaluated the occurrence and persistence of delirium in 325 elderly patients admitted to a teaching hospital from either a defined community or a long-term care facility. Of the study participants, 34 (10.5%) had Diagnostic and Statistical Manual of Mental Disorders, Third Edition-defined delirium at initial evaluation; of the remaining patients, 91 (31.3%) developed new-onset delirium. An additional 110 patients also experienced individual symptoms of delirium without meeting full criteria. Preexisting cognitive impairment and advanced age were associated with increased risk of incident delirium in the community sample but not the institutional one. Delirium was not associated with an increased risk of mortality, but it was associated with a prolonged hospital stay and an increased risk of institutional placement among community-dwelling elderly. Only five patients (4%) experienced resolution of all new symptoms of delirium before hospital discharge, and only 20.8% and 17.7%, respectively, had resolution of all new symptoms by 3 and 6 months after hospital discharge. These data suggest that delirium is a common disorder that may be substantially less transient than currently believed and that incomplete manifestations of the syndrome may be frequent.
