| 摘 要： | 在参考临床研究的相关数据标准和电子病历相关数据标准基础上,构建前瞻性临床研究元数据的宏观框架、中观类组和微观属性等三个层面的元数据语义架构体系(openPCR)。openPCR的宏观框架结构包括临床研究、公用元数据、内部元数据和研究数据集4个部分;中观类组结构是对公用元数据、内部元数据和研究数据集进一步细化后形成的结构;微观属性结构从标识类、定义类、管理类、关系类和表示类来详细描述各级元数据。openPCR成为建立前瞻性临床研究数据库的语义结构体系,为前瞻性临床研究的数据标准化、数据交换与共享以及与电子病历系统的兼容奠定基础。

| Abstract: | Based on the related clinical data standards and Electronic Health Record(EHR) standards, the authors construct a three-level semantic system for prospective clinical research (openPCR),which includes a framework structure,a medium level structure and a data attribute structure. For its framework structure,it covers clinical research design,clinical research header and clinical research body,and data group of clinical research body. For its medium level structure,it extends into data elements of name,status,beginning time,end time,results and other qualifiers. For its data attribute structure,it is further composed of identifier,definition,administration,relationship and representation. As a semantic system for the prospective clinical research,openPCR lays the foundation for the data standardization,exchange and sharing of prospective clinical research,and for its compatibility with EHR system. |
