公共卫生信息分类与编码研究

Study on classification and coding for public health information

目的建立公共卫生数据集分类框架与编码体系,实现对公共卫生数据集信息的统一描述、标识、查询和管理。方法以公共卫生领域各项业务、科研和管理活动中产生的能够通过信息系统进行处理的基本数据集为分类对象,采用线分类与面分类法相结合的方法,按小类、子类、主类、主题域4个层级构建分类框架,并依次对具有共同主题特征的公共卫生数据集进行逐级抽象与归并,生成各层级类目,再应用组配技术对数据集进行系统编码。结果(1)建立了包括疾病预防控制、公共卫生服务、公共卫生管理和卫生监督4个主题域,18个主类,49个子类,205个小类的公共卫生信息分类框架;(2)设计了由7位主分类代码和包括地区代码、组织机构代码、疾病分类代码和学科分类代码4段30位复分类代码组成的编码体系。应用公共卫生9个业务领域提供的50个基本数据集进行分类归入效能检验和编码检索测试,均达到预期目标。结论认为这种分类与编码方法适用于公共卫生领域信息资源交换的分类与编码实践。

Objective To improve data unified descriptions, identification, query and management in public health service by means of establishing public health information classification framework and coding system. Methods Data sets created from all fields in publich health, scientific research, health management were classified into four layers of framworks primary class, sub-class, main class and subject areas by means of integration of vertical with horizontal classifications. All these classes were further abstracted, merged and coded by individual characteristics in public health systems. Results （ 1 ）4 subject areas in diseases control and prevention, public health service, public health management and sanitation surveillance were established including a total of 18 main classes, 49 sub-classes and 205 primary classes. （2） 7 digits and 4 segments （ area code, code, disease classification code ） were designed including a total of 30 digits multi-classification codes. The purpose of data effectively classifying and coding by application of 50 basic data sets in 9 areas fo public health has been realized. Conclusion We believe that this method is of efficiency in data classification and code for public health information communication.
