Our aim was to develop a reference functional model for electric health record systems (RFM). Such a RFM is built from functions using functional descriptive elements (FDEs) and represents the static relationships between them. This paper presents a new format for describing electric health record (EHR) system functions.
Questionnaire and field interview survey was conducted in five hospitals in Japan and one in the USA, to collect data on EHR system functions. Based on survey results, a reference functional list (RFL) was created, in which each EHR system function was listed and divided into 13 FDE types. By analyzing the RFL, we built the meta-functional model and the functional model using UML class diagrams. The former defines language for expressing the functional model, while the latter represents functions, FDEs and their static relationships.
A total of 385 functions were represented in the RFL. Six patterns were found for the relationships between functions. The meta-functional model was created as a new format for describing functions. Examples of the functional model, which included the six patterns in the relationships between functions and 11 verbs, were created.
We present the meta-functional model, which is a new description format for the functional structure and relationships. Although a more detailed description is required to apply the RFM to the semiautomatic generation of functional specification documents, our RFM can visualize functional structures and functional relationships, classify functions using multiple axes and identify the similarities and differences between functions. The RFM will promote not only the standardization of EHR systems, but also communications between system developers and healthcare providers in the EHR system-design processes.
我们的目标是开发一个电子健康记录系统（RFM）的参考功能模型。这样的RFM是由使用功能描述元素（FDE）的功能构建而成的，并表示它们之间的静态关系。本文提出了一种描述电子健康记录（EHR）系统功能的新格式。
在日本的五家医院和美国的一家医院进行了问卷调查和实地访谈，以收集有关EHR系统功能的数据。根据调查结果，创建了一个参考功能列表（RFL），其中列出了每个EHR系统功能，并将其分为13种FDE类型。通过分析RFL，我们使用UML类图构建了元功能模型和功能模型。前者定义了用于表达功能模型的语言，而后者表示功能、FDE及其静态关系。
RFL中总共表示了385个功能。发现了功能之间关系的六种模式。创建了元功能模型作为描述功能的新格式。创建了功能模型的示例，其中包括功能之间关系的六种模式和11个动词。
我们提出了元功能模型，它是功能结构和关系的一种新的描述格式。尽管要将RFM应用于功能规范文档的半自动生成还需要更详细的描述，但我们的RFM可以可视化功能结构和功能关系，使用多个轴对功能进行分类，并识别功能之间的异同。RFM不仅将促进EHR系统的标准化，还将促进EHR系统设计过程中系统开发人员与医疗保健提供者之间的沟通。
