Arden Syntax is a widely recognized standard for representing clinical and scientific knowledge in an executable format. It has a history that reaches back until 1989 and is currently maintained by the Health Level 7 (HL7) organization. We created a production-ready development environment, compiler, rule engine and application server for Arden Syntax. Over the course of several years, we have applied this Arden - Syntax - based CDS system in a wide variety of clinical problem domains, such as hepatitis serology interpretation, monitoring of nosocomial infections or the prediction of metastatic events in melanoma patients. We found the Arden Syntax standard to be very suitable for the practical implementation of CDS systems. Among the advantages of Arden Syntax are its status as an actively developed HL7 standard, the readability of the syntax, and various syntactic features such as flexible list handling. A major challenge we encountered was the technical integration of our CDS systems in existing, heterogeneous health information systems. To address this issue, we are currently working on incorporating the HL7 standard GELLO, which provides a standardized interface and query language for accessing data in health information systems. We hope that these planned extensions of the Arden Syntax might eventually help in realizing the vision of a global, interoperable and shared library of clinical decision support knowledge.
Arden 语法是一种广泛认可的标准，用于以可执行格式表示临床和科学知识。它的历史可以追溯到 1989 年，目前由健康水平 7（HL7）组织维护。我们为 Arden 语法创建了一个生产就绪的开发环境、编译器、规则引擎和应用服务器。几年来，我们已经在各种临床问题领域（如肝炎血清学解释、医院感染监测或黑色素瘤患者转移事件预测）中应用了这个基于 Arden 语法的 CDS 系统。我们发现 Arden 语法标准非常适合实用的 CDS 系统实现。Arden 语法的优点包括它作为一个活跃开发的 HL7 标准的地位、语法的可读性，以及灵活的列表处理等各种语法特性。我们遇到的一个主要挑战是在现有的异构健康信息系统中技术集成我们的 CDS 系统。为了解决这个问题，我们目前正在努力整合 HL7 标准 GELLO，它为访问健康信息系统中的数据提供了标准化的接口和查询语言。我们希望 Arden 语法的这些计划扩展最终有助于实现全球、互操作和共享临床决策支持知识库的愿景。
