健康信息学 - 医疗信息服务架构 - 第2部分:信息观点

[中文适用范围]： 本文件规定了信息系统特定架构层（即服务架构）实现的信息模型的基本特征，以提供通用企业数据的全面集成存储并支持医疗保健组织的基本业务流程，如 ISO 12967-1 中定义。 本文件中指定的信息模型没有对各种目标场景中物理实现所采用的物理技术、工具或解决方案进行任何明确或隐含的假设。 然而，该规范是正式的、完整的和明确的，足以允许实施者在为物理实施选择的特定技术环境中导出系统的有效设计。 本文件并不旨在代表任何医疗保健企业的任何要求所需的所有可能数据的固定、完整的规范。 它仅根据整体组织和单个信息对象指定一组特征，这些特征被确定为所有医疗保健组织的基本和公共特征，并且由服务架构实现的信息模型满足。 为了保持与本文档规定的一致性，物理实现允许对标准信息模型进行扩展，以支持附加的和本地的需求。 扩展包括标准模型对象中附加属性的定义以及全新对象的实现。 此外，该文档规范可以根据适用标准化计划的发展随着时间的推移进行扩展。 扩展规范根据 ISO 12967-1:2020 第 7 条中定义的方法进行。 [外文原描述]： This document specifies the fundamental characteristics of the information model implemented by a specific architectural layer (i.e. the service architecture) of the information system to provide a comprehensive and integrated storage of the common enterprise data and to support the fundamental business processes of the healthcare organization, as defined in ISO 12967‑1. The information model is specified in this document without any explicit or implicit assumption on the physical technologies, tools or solutions to adopt for its physical implementation in the various target scenarios. The specification is nevertheless formal, complete and non-ambiguous enough to allow implementers to derive an efficient design of the system in the specific technological environment that will be selected for the physical implementation. This document does not aim at representing a fixed, complete, specification of all possible data that can be necessary for any requirement of any healthcare enterprise. It specifies only a set of characteristics, in terms of overall organization and individual information objects, identified as fundamental and common to all healthcare organizations, and that is satisfied by the information model implemented by the service architecture. Preserving consistency with the provisions of this document, physical implementations are allowed extensions to the standard information model in order to support additional and local requirements. Extensions include both the definition of additional attributes in the objects of the standard model, and the implementation of entirely new objects. Also, this document specification is extensible over time according to the evolution of the applicable standardization initiatives. The specification of extensions is carried out according to the methodology defined in ISO 12967-1:2020, Clause 7.
