PROJECT SUMMARY More than one third of patients in the intensive care unit (ICU) develop ICU delirium, an acute, fluctuating form of cognitive dysfunction that is associated with increased mortality, and longer ICU lengths of stay and days of mechanical ventilation; and disproportionately increases the risk for long-term cognitive impairment. Disrupted sleep in the ICU is thought to contribute to development of ICU delirium, however the sleep-delirium relationship has not been rigorously investigated. Although ICU patients maintain adequate sleep duration per 24 hours, sleep architecture is severely disrupted. Namely, there is a marked decrease in rapid eye movement (REM) sleep compared to healthy adults. Insufficient REM sleep has been associated with neurodegenerative disease such as dementia, which has similar characteristics to ICU delirium. Less REM sleep has been observed in patients with, compared to without ICU delirium, although the temporality is unclear. To date, few studies have investigated sleep prior to development of ICU delirium, and no studies account for objective baseline sleep. We propose a novel approach to address these critical gaps by leveraging a population of thoracic surgery candidates with a planned post-operative ICU admission to enable baseline sleep evaluation. Research: The K99 phase study will evaluate clinical and demographic predictors of percentage of days with ICU delirium or coma (DoDC) in the acute ICU phase (days 1 up to 14) in a retrospective electronic health record study of thoracic surgery patients (N=4,849) at the University of Pennsylvania Health System (UPHS) from 2015-present. As sleep is not routinely assessed in the ICU, it is not possible to evaluate sleep from medical records. Therefore, we will first identify non-sleep predictors of ICU delirium to then be able to evaluate if sleep indices measured in future studies explains a substantial percentage of the variance in ICU delirium not accounted for by non-sleep predictors. The R00 phase study will evaluate the difference in mean minutes of REM sleep per night for patients with and without ICU delirium in a prospective observational cohort study of thoracic surgery candidates from UPHS (N=148). Sleep will be assessed using wireless electroencephalography at baseline (pre-ICU), and post-operatively in the ICU for 3 days each. In a subset of the R00 cohort (N=20), frequency of awakenings from sleep due to the ICU environment will be assessed. Results from these studies will be used to inform development of future sleep-promoting interventions. Training: To achieve overall career goals, the training plan will build upon the candidate’s background in critical care and sleep in healthy individuals by affording her in-depth training in learning about sleep in clinical and ICU populations, and training in ICU delirium mechanisms and development of predictive models. This training will also include advancing her scientific dissemination skills, as well as development of the skills needed to become a leader in the scientific community. A variety of approaches will be used to achieve these goals including formal coursework, hands-on training, and structured one-on-one mentorship.

项目摘要 重症监护公正（ICU）中有超过三分之一的患者发展为del妄，这是一种急性波动形式 与死亡率增加有关的认知功能障碍以及较长的ICU的住院时间和天数 机械通风和不动力增加了长期认知障碍的风险。 ICU中的睡眠被认为有助于ICU妄想的发展 尚未对关系进行严格研究。 24小时，睡眠结构被认为是迅速移动的明显下降 （REM）与健康的成年人相比睡眠。 诸如痴呆症之类的疾病，其特征与ICU del妄具有类似的特征。 与没有ICU妄想的患者相比，在迄今为止尚不清楚的患者中观察到 研究在开发ICU del妄之前已经调查了睡眠，没有任何研究解释客观 基线睡眠。 带有计划的术后ICU入院的胸外科手术候选物，以实现基线睡眠评估。 研究：K99阶段研究将评估临床和人口统计学预测因素 在回顾性电子健康中，急性ICU阶段（最多14天）中的ICU del妄或昏迷（DODC） 宾夕法尼亚大学卫生系统（UPHS）的胸外科手术患者（n = 4,849）的记录研究 从2015年至今，没有经常评估ICU的睡眠 因此，我们将首先要评估ICU 如果未来的研究中测量的睡眠指标解释了ICU deli妄差异的很大一部分 通过非睡眠预测指标，R00阶段研究将评估平均分钟的差异 在前瞻性观察队列研究中，每名患有和没有ICU del妄的患者的REM睡眠 UPHS的胸手术候选物（n = 148）。 基线的脑电图（Pref-ICU），并在ICU中进行3天。 R00队列（n = 20），将对ICU环境引起的睡眠觉醒的频率进行评估。 研究的结果将用于告知未来促进睡眠干预措施的发展。 培训：为了实现整体职业目标，培训计划将以候选人的背景为基础 健康个体的重症监护和睡眠，通过为临床中的雨夹雪提供深入的培训。 ICU Poptions以及ICU ir妄机制的培训和预测模型的发展 培训还将包括提高她的科学传播技巧以及发展技能 需要成为科学界的领导者。 目标包括正式课程，动手培训和结构化的一对一指导。
