The factors advanced as casual agents of acute confusion span the full spectrum of human illnesses and are of physiologic, psychologic, sociologic, and environmental origins. Although it is generally agreed that acute confusion is the result of multiple factors interacting over time, most investigations into the causes of confusion, however, have utilized univariate, single-subject, or single-time designs. But, if the assumption is to be accepted that multiple interacting agents cause confusion, then studies must be of multivariate, multidimensional, and longitudinal designs. Thus, the purpose of the proposed study is to test a three-wave, longitudinal, causal model of confusion. The three waves, or time periods to be examined are: Time I--Admission to the hospital, Time 2--Onset of acute confusion; and Time 3--Resolution of acute confusion. To test the hypothesized causal/model, 1050 medically-ill patients 65 years of age or older will be interviewed and hospital records reviewed daily while hospitalized. These semi-structured interviews and their hospital record reviews will be used to obtain information about cerebral metabolism, neural and sensory structure and function, social dynamics, affective status, and aspects of the environment; all of which are factors considered casually related to acute confusion. These data will be analyzed within Levine's Conservation Model of Nursing in a three-wave longitudinal casual model using linear structural relationship modeling, or LISREL. Information necessary for developing appropriate and effective strategies for the nursing care relative to acute confusion (specifically detection, prevention, prediction, and intervention) of this patient population will be derived from the resultant model.

随着急性混乱的休闲代理的发展，这些因素跨越了 人类疾病的范围，具有生理，心理学， 社会学和环境起源。尽管人们普遍认为 急性混乱是多种因素随时间相互作用的结果， 但是，大多数对混乱原因的调查都使用了 单变量，单个主体或单时间设计。但是，如果假设 被认为多种相互作用剂会引起混乱，然后 研究必须具有多元，多维和纵向 设计。因此，拟议的研究的目的是测试三波， 纵向，因果混乱模型。三波或时间段 被检查的是：时间I-到医院，时间2- 急性混乱；时间3-急性混乱的解决方案。测试 假设的因果/型号，1050名医学界的患者65岁或 较旧的人将接受采访，医院记录每天审查 住院。这些半结构化访谈及其医院记录 评论将用于获取有关大脑代谢的信息， 神经和感觉结构和功能，社会动态，情感 地位和环境方面；所有这些都是考虑因素 随便与急性混乱有关。这些数据将在其中分析 莱文在三波纵向休闲中的护理保护模型 使用线性结构关系建模或Lisrel的模型。信息 为制定适当有效的策略所必需的 相对于急性混乱的护理保健（特别是检测， 该患者人群的预防，预测和干预将 从结果模型中得出。
