Medical devices are essential to the practice of modern healthcare services. Their benefits will increase if clinical software applications can seamlessly acquire the medical device data. The need to represent medical device observations in a format that can be consumable by clinical applications has already been recognized by the industry. Yet, the solutions proposed involve bilateral mappings from the ISO/IEEE 11073 Domain Information Model (DIM) to specific message or document standards. Considering that there are many different types of clinical applications such as the electronic health record and the personal health record systems, the clinical workflows, and the clinical decision support systems each conforming to different standard interfaces, detailing a mapping mechanism for every one of them introduces significant work and, thus, limits the potential health benefits of medical devices. In this paper, to facilitate the interoperability of clinical applications and the medical device data, we use the ISO/IEEE 11073 DIM to derive an HL7 v3 Refined Message Information Model (RMIM) of the medical device domain from the HL7 v3 Reference Information Mode (RIM). This makes it possible to trace the medical device data back to a standard common denominator, that is, HL7 v3 RIM from which all the other medical domains under HL7 v3 are derived. Hence, once the medical device data are obtained in the RMIM format, it can easily be transformed into HL7-based standard interfaces through XML transformations because these interfaces all have their building blocks from the same RIM. To demonstrate this, we provide the mappings from the developed RMIM to some of the widely used HL7 v3-based standard interfaces.
医疗设备对于现代医疗服务的实践至关重要。如果临床软件应用程序能够无缝获取医疗设备数据,其益处将会增加。业界已经认识到需要以临床应用程序可使用的格式来表示医疗设备观测数据。然而,所提出的解决方案涉及从ISO/IEEE 11073领域信息模型(DIM)到特定消息或文档标准的双边映射。鉴于存在许多不同类型的临床应用程序,如电子健康记录和个人健康记录系统、临床工作流程以及临床决策支持系统,它们各自符合不同的标准接口,为每一个应用程序详细描述映射机制会带来大量工作,因此限制了医疗设备潜在的健康益处。在本文中,为促进临床应用程序与医疗设备数据的互操作性,我们使用ISO/IEEE 11073 DIM从HL7 v3参考信息模型(RIM)中导出医疗设备领域的HL7 v3精炼消息信息模型(RMIM)。这使得能够将医疗设备数据追溯到一个标准公分母,即HL7 v3 RIM,HL7 v3下的所有其他医疗领域均由此派生而来。因此,一旦以RMIM格式获取医疗设备数据,就可以通过XML转换轻松将其转换为基于HL7的标准接口,因为这些接口的构建块都来自同一个RIM。为证明这一点,我们提供了从所开发的RMIM到一些广泛使用的基于HL7 v3的标准接口的映射。
