标准范围

本文件规定了由信息系统的特定体系结构层（即服务体系结构）实现的计算模型的基本特征，以提供通用企业信息的全面集成接口，并支持ISO 12967-1中定义的医疗保健组织的基本业务流程。指定计算模型时，未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、不含糊的，足以允许实施者在特定的技术环境中得出系统的有效设计，该技术环境将被选择用于物理实施。本文件中规定的计算模型为确保不同工程和技术规范（包括编程语言和通信机制）之间的一致性提供了基础，因为它们旨在与相同的计算对象模型保持一致。这种一致性允许组件在最终实现中开放式交互工作和可移植性。本文档的目的不是为任何医疗保健企业的任何需求所需的所有可能接口提供一个固定、完整的规范。它只指定了一组特征——就整体组织和单个计算对象而言，这些特征被确定为所有医疗保健组织的基本特征和共同特征，并且由服务体系结构实现的计算模型满足这些特征。为了保持与本文件规定的一致性，本文件中规定的计算模型的物理实现可以允许扩展，以支持附加和本地需求。扩展可以包括本文档中指定的计算模型对象的附加属性的定义，以及全新对象的实现。此外，根据ISO 12967？1:2020第7条中定义的方法论，本文件中规定的计算模型可以根据适用标准化计划的演变随时间扩展，该方法论确定了一组医疗保健通用信息服务，描述了其背后的要求以及将使用这些服务的方法。本文件中规定的信息服务只是根据医疗保健企业确定的需求确定的最小集合，构成服务架构（即集成平台），作为医疗保健应用（如EHR或患者管理）的基础。

This document specifies the fundamental characteristics of the computational model implemented by a specific architectural layer of the information system (i.e. the service architecture) to provide a comprehensive and integrated interface to the common enterprise information and to support the fundamental business processes of the healthcare organization, as defined in ISO 12967？1. The computational model is specified without any explicit or implicit assumption about 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 which will be selected for the physical implementation.The computational model specified in this document provides the basis for ensuring consistency between different engineering and technology specifications (including programming languages and communication mechanisms) since they are intended to be consistent with the same computational object model. This consistency allows open inter-working and portability of components in the resulting implementation.This document does not aim at representing a fixed, complete, specification of all possible interfaces that might be necessary for any requirement of any healthcare enterprise. It specifies only a set of characteristics — in terms of overall organization and individual computational objects, identified as fundamental and common to all healthcare organizations, and that are satisfied by the computational model implemented by the service architecture.Preserving consistency with the provisions of this document, physical implementations of the computational model specified in this document can allow extensions in order to support additional and local requirements. Extensions can include both the definition of additional properties of the objects of the computational model specified in this document and the implementation of entirely new objects.Also, the computational model specified in this document can be extendable over time according to the evolution of the applicable standardization initiatives, in accordance to the methodology defined in ISO 12967？1:2020, Clause 7, which identifies a set of healthcare common information services, describing the requirements behind them and the methodology through which they will be used.The information services specified in this document are only the minimal set identifiable according to the identified requirements of the healthcare enterprise, and constituting the service architecture (i.e. the integration platform) to serve as the basis for healthcare applications, e.g. EHR or patient administration.
