电子健康记录(EHR)数据已成为人口健康和临床研究的重要资源。人们已经做出了很大的努力来利用EHR数据进行研究;然而,考虑到数据安全问题和数据的复杂性,EHR数据通常难以访问和用于临床研究。我们描述了临床研究数据集市(CRDM)的发展,该数据集市的发展是为了向杜克大学的研究人员提供精心策划和易于访问的EHR数据。CRDM旨在(1)包含研究所需的大多数患者级数据元素;(2)可由进行统计分析的个人直接访问(包括生物统计学、流行病学和研究设计(BERD)核心成员);(3)通过基于代码的系统进行查询,以促进研究之间的重现性和一致性;以及(4)利用安全的受保护的分析工作空间,其中可以存储和分析敏感的EHR数据。中央档案数据库利用为太平洋共同体区域办事处网络数据网转换的数据,并增加了含有特定地点数据要素的额外数据表,以提供额外的背景信息。我们提供了理想用例的描述,并讨论了传播和评估方法,包括未来的工作,以扩大用户群和跟踪使用和影响的数据资源。CRDM利用作为临床和转化科学奖(CTSA)计划的一部分开发的资源,并可由其他具有CTSA的机构复制。
Electronic health record (EHR) data have emerged as an important resource for population health and clinical research. There have been significant efforts to leverage EHR data for research; however, given data security concerns and the complexity of the data, EHR data are frequently difficult to access and use for clinical studies. We describe the development of a Clinical Research Datamart (CRDM) that was developed to provide well-curated and easily accessible EHR data to Duke University investigators. The CRDM was designed to (1) contain most of the patient-level data elements needed for research studies; (2) be directly accessible by individuals conducting statistical analyses (including Biostatistics, Epidemiology, and Research Design (BERD) core members); (3) be queried via a code-based system to promote reproducibility and consistency across studies; and (4) utilize a secure protected analytic workspace in which sensitive EHR data can be stored and analyzed. The CRDM utilizes data transformed for the PCORnet data network, and was augmented with additional data tables containing site-specific data elements to provide additional contextual information. We provide descriptions of ideal use cases and discuss dissemination and evaluation methods, including future work to expand the user base and track the use and impact of this data resource. The CRDM utilizes resources developed as part of the Clinical and Translational Science Awards (CTSAs) program and could be replicated by other institutions with CTSAs.
