摘要
元数据标准是描述某类资源的具体对象时所有规则的集合,用来规范数据采集、存储、传输、计算和展示等过程,能有效提高数据处理效率和质量。本文从已有数据标准特点和应用等角度,对临床研究领域现有元数据标准情况进行整理,为进一步推进相关研究提供参考,以期促进临床研究规范化、疗效评价客观科学化。
A metadata standard is a high level document that establishes a common way of structuring and understanding data,and includes principles and implementation issues for utilizing the standard.It helps to record their collections and processes and to structure this information,and can be used to validate data integrity and quality.Metadata standards improve the quality and interoperability of information across information technology platforms by increasing compatibility,improving the consistency and efficiency of information collection,and reducing redundancy.This article introduced the progress and features of metadata standards of clinical research,and aimed to promote the standardization of clinical research and scientific process of therapeutic evaluation.
