项目摘要

Project Summary Pulmonary embolism (PE) is a leading cause of death in the United States. Risk stratification for acute PE treatment can reduce mortality. Risk scoring systems use clinical and laboratory electronic medical record (EMR) data. In addition, biomarkers on computed tomography imaging can identify which patients with PE are at high risk of death, independent of clinical data. Despite advances in clinical and image-driven scoring systems, improving outcomes in acute PE depends on implementation of patient-specific EMR and imaging data analytic prognostic models at the point of care. The promise of digital medicine stems in part from the hope that by digitizing health data, we can leverage computer information systems to understand and improve care. A method that can make use of these data to predict patient-specific outcomes could not only provide major benefits for patient safety and healthcare quality but also reduce healthcare costs. Unfortunately, most of this information is not yet included in predictive statistical models that clinicians use to improve care delivery. This is because traditional computational methods and techniques are insufficient at accurately analyzing such high volumes of heterogeneous data. The goal of this proposal is to develop an automated precision medicine approach to achieve point-of-care risk stratification for PE patient outcomes using a fusion deep learning strategy that can simultaneously analyze health records and imaging data. An ideal PE risk-scoring system would not only predict mortality, but also assess the risk for the many debilitating long-term consequences of acute PE. Such a system would, therefore, facilitate optimal management and would likely require intelligent use of clinical, laboratory, and imaging data together in order to provide accurate patient -specific risk scoring for multiple PE outcome measures. In order to build a robust model, we propose to apply distributed training of deep learning models across four large US healthcare institutions. By distributing the algorithm rather than the data, we avoid sharing individually identifiable patient information. If successful, this project will be the first endeavor to leverage diagnostic imaging (pixel) data in combination with structured and unstructured EMR data to predict outcomes. We have the ideal research team, experience, and methods to develop an automated risk-scoring system for acute PE patients. Using a powerful combination of clinical, laboratory, and imaging data, this system will provide patient-specific risk scoring for multiple PE outcome measures. Further, this project will foster multi- center collaborations, which will afford us the opportunity to investigate the generalizability of our approach to different populations of PE patients and to train, test, and ultimately deploy our automated predictive model in a variety of clinical environments.

项目摘要肺栓塞（PE）是美国死亡的主要原因。急性PE的风险分层治疗可以降低死亡率。风险评分系统使用临床和实验室电子病历（EMR）数据。此外，计算机断层扫描成像上的生物标志物可以识别哪些PE患者是死亡的高风险，独立于临床数据。尽管临床和图像驱动的得分进展系统，改善急性PE的预后取决于患者特异性EMR的实施数据分析预后模型在护理点。数字医学的承诺部分源于希望通过数字化健康数据，我们可以利用计算机信息系统以了解和改善护理。可以利用这些数据来预测特定于患者的结果不仅可以为患者安全和医疗保健质量带来重大好处但也降低医疗保健成本。不幸的是，大多数此信息尚未包含在预测中临床医生用来改善护理提供的统计模型。这是因为传统计算方法和技术不足以准确分析如此大量的异质数据。该建议的目的是开发一种自动精确医学方法来达到护理风险使用融合深度学习策略的PE患者结果分层，该策略可以同时分析健康记录和成像数据。理想的PE评分系统不仅可以预测死亡率，还可以预测评估急性PE的许多令人衰弱的长期后果的风险。这样的系统会，因此，促进最佳管理，可能需要明智地使用临床，实验室和一起成像数据，以便为多个PE结果提供准确的患者风险评分措施。为了建立一个强大的模型，我们建议应用深度学习模型的分布式培训在四家大型美国医疗机构中。通过分发算法而不是数据，我们避免共享单独识别的患者信息。如果成功，该项目将是第一个努力利用诊断成像（像素）数据与结构化和非结构化EMR数据结合使用以预测结果。我们拥有理想的研究团队，经验和方法，以开发一个自动化的风险评分系统急性PE患者。使用临床，实验室和成像数据的强大组合，该系统将为多种PE结果指标提供特定于患者的风险评分。此外，该项目将促进多中心合作，这将使我们有机会调查我们方法的普遍性 PE患者的不同种群，并在各种临床环境。
