The Clinical Emergency Data Registry (CEDR) is a qualified clinical data registry that collects data from participating emergency departments (EDs) in the United States for quality measurement, improvement, and reporting purposes. This article aims to provide an overview of the data collection and validation process, describe the existing data structure and elements, and explain the potential opportunities and limitations for ongoing and future research use. CEDR data are primarily collected for quality reporting purposes and are obtained from diverse sources, including electronic health records and billing data that are de-identified and stored in a secure, centralized database. The CEDR data structure is organized around clinical episodes, which contain multiple data elements that are standardized using common data elements and are mapped to established terminologies to enable interoperability and data sharing. The data elements include patient demographics, clinical characteristics, diagnostic and treatment procedures, and outcomes. Key limitations include the limited generalizability due to the selective nature of participating EDs and the limited validation and completeness of data elements not currently used for quality reporting purposes, including demographic data. Nonetheless, CEDR holds great potential for ongoing and future research in emergency medicine due to its large-volume, longitudinal, near real-time, clinical data. In 2021, the American College of Emergency Physicians authorized the transition from CEDR to the Emergency Medicine Data Institute, which will catalyze investments in improved data quality and completeness for research to advance emergency care.

临床紧急数据登记：结构、使用和研究限制


临床急诊数据登记处 (CEDR) 是一个合格的临床数据登记处，从美国参与的急诊科 (ED) 收集数据，用于质量测量、改进和报告目的。本文旨在概述数据收集和验证过程，描述现有的数据结构和元素，并解释正在进行和未来研究使用的潜在机会和限制。 CEDR 数据主要出于质量报告目的而收集，并从不同来源获取，包括去识别化并存储在安全的集中式数据库中的电子健康记录和账单数据。 CEDR 数据结构围绕临床事件进行组织，其中包含多个数据元素，这些数据元素使用通用数据元素进行标准化，并映射到已建立的术语以实现互操作性和数据共享。数据元素包括患者人口统计、临床特征、诊断和治疗程序以及结果。主要局限性包括由于参与的 ED 的选择性而导致的普遍性有限，以及目前未用于质量报告目的的数据元素（包括人口统计数据）的验证和完整性有限。尽管如此，CEDR 由于其大量、纵向、近实时的临床数据，对于正在进行和未来的急诊医学研究具有巨大潜力。 2021 年，美国急诊医师学会授权从 CEDR 过渡到急诊医学数据研究所，这将促进对提高研究数据质量和完整性的投资，以推进急诊护理。
