PROJECT SUMMARY Sepsis is a major health challenge worldwide that is associated with a significant risk of mortality. The key to improved outcomes in sepsis is earlier treatment once diagnosed, with delays in therapy being associated with worse outcomes. Sepsis is a heterogenous disease, and thus despite decades of research focused on various aspects of sepsis, there still remains much to be learned about the underlying mechanisms that result in differences in outcomes. The utilization of biorepositories gives investigators the opportunity to study different mechanisms of disease; however, it is imperative that we collect biospecimens early on in disease and at different time point in order to understand disease trajectory. Furthermore, there are opportunities within critical care research to diversify the patient population enrolled in studies in order to investigate disparities that occur in sepsis. Thus, the need to develop best practices and standard operation procedures are required that may serve as templates for establishing scalable and generalizable sepsis biorepositories. This proposal aims to 1) develop an integrated multi-modal clinical, physiologic, volatilomic, and multi-omic biorepository profile driven by a semi-autonomous screening algorithm to enrich sepsis phenotypes; 2)design and test novel methods of biospecimen collection among enriched sepsis populations in both ambulance and acute care hospital environments ; and 3)develop novel approaches to biorepository consent that match the clinical context of sepsis, maximize representativeness among patients, and enhance trust and engagement among patients and surrogate decision-makers.

项目概要 脓毒症是世界范围内的一项重大健康挑战，与重大死亡风险相关。关键是 脓毒症预后的改善在于诊断后尽早治疗，治疗延迟与以下因素有关： 更糟糕的结果。脓毒症是一种异质性疾病，因此尽管数十年的研究集中于各种 脓毒症的各个方面，关于导致脓毒症的潜在机制仍有很多需要了解 结果的差异。生物样本库的利用使研究人员有机会研究不同的 疾病机制；然而，我们必须在疾病早期和早期收集生物样本 不同时间点以了解疾病轨迹。此外，内部还有机会 重症监护研究使参与研究的患者群体多样化，以调查以下差异： 发生于败血症。因此，需要制定最佳实践和标准操作程序 这可以作为建立可扩展和通用的脓毒症生物库的模板。这个提议 目标是 1) 开发一个集成的多模式临床、生理、挥发性和多组学生物样本库 由半自主筛选算法驱动的概况，以丰富脓毒症表型； 2）设计和测试新颖 在救护车和急症护理中丰富的脓毒症人群中采集生物样本的方法 医院环境； 3）开发符合临床的生物样本库同意新方法 败血症的背景下，最大限度地提高患者的代表性，并增强患者之间的信任和参与 患者和代理决策者。
