DESCRIPTION (provided by applicant): Premature infants in the Neonatal ICU require hospitalization until they reach physiological maturity, an average of 60 days. While in the hospital, though, they are at risk of sub-acute potentially catastrophic illnesses such as infectio, respiratory decompensation leading to urgent unplanned intubation, and intracranial bleeding. These illnesses are common and deadly. In each case, early diagnosis has the promise to improve outcome through early intervention. The long-term goal of our group is to develop such novel predictive monitoring strategies as early warning systems through advanced mathematical and statistical analysis of waveforms and other informatics data from the bedside monitor. This kind of approach recently led the group and its colleagues at 7 other centers to complete a NICHD- sponsored randomized clinical trial in 3000 premature infants, the largest ever conducted in this population. The result was very important - simply showing the results of a predictive monitor to clinicians reduced the death rate by more than 20%. The overall conceptual framework is that some sub-acute potentially catastrophic illnesses have subclinical prodromes with abnormal physiologic signatures. This is based on ideas about the systemic inflammatory response syndrome and the cholinergic anti-inflammatory pathway that link inflammation to abnormal signal transduction and autonomic nervous system activity. The result is that illness, even in early stages, leads to uncoupling of organs and abnormal control of heart and respiratory rhythms that can be detected using mathematical algorithms tailored to clinical insights. Achieving our goals of predictive informatics monitoring requires a large database of relevant clinical information and monitor data from the University of Virginia NICU, including vita signs and waveforms. The team of clinicians and mathematicians - a collaboration of University of Virginia and Columbia University - will discover phenotypes of abnormal physiology and develop algorithms to detect them. The large-scale computing capability for this work is in daily use, and the group will be poised to undertake randomized clinical trials to test the impact of the new monitoring. This represents a paradigm shift in patient care - monitors that report trends of development of health and illness rather than fleeting values.

描述（由申请人提供）：新生儿ICU中的早产儿需要住院治疗，直到他们达到生理成熟，平均60天。然而，在住院期间，他们面临着亚急性潜在灾难性疾病的风险，如感染、呼吸失代偿导致紧急计划外插管和颅内出血。这些疾病是常见的和致命的。在每种情况下，早期诊断都有希望通过早期干预改善结果。我们小组的长期目标是通过对来自床边监护仪的波形和其他信息学数据进行先进的数学和统计分析，开发诸如早期预警系统之类的新型预测性监测策略。这种方法最近导致该小组及其在其他7个中心的同事完成了一项由NICHD赞助的3000名早产儿的随机临床试验，这是有史以来在这一人群中进行的最大规模的试验。结果非常重要--仅仅向临床医生展示预测监测的结果就可以将死亡率降低20%以上。总体概念框架是，一些亚急性潜在的灾难性疾病具有异常生理特征的亚临床表现。这是基于全身炎症反应综合征和胆碱能抗炎通路的想法，将炎症与异常信号转导和自主神经系统活动联系起来。其结果是，即使在早期阶段，疾病也会导致器官的分离以及心脏和呼吸节律的异常控制，这些都可以使用针对临床见解的数学算法来检测。实现我们的预测信息监测目标需要一个大型的相关临床信息数据库和来自弗吉尼亚大学NICU的监测数据，包括vita体征和波形。由临床医生和数学家组成的团队--由弗吉尼亚大学和哥伦比亚大学合作--将发现异常生理学的表型，并开发检测它们的算法。这项工作的大规模计算能力已在日常使用中，该小组将准备进行随机临床试验，以测试 新的监测。这代表了病人护理的范式转变-监测器报告健康和疾病的发展趋势，而不是短暂的价值观。
