Insufficient requirements analysis has recently been suggested as a problem in clinical decision-support systems development. Therefore, to explore knowledge, practices and attitudes, key professionals in the area from four countries were interviewed regarding the early phases in the development process. For data collection, semi-structured interviews were performed and video-taped. As reference, documentation of the Action Design requirements engineering methodology was used. Two separate qualitative analyses of the data were made. The first was to identify central concepts and attitudes related to requirements engineering. In the second analysis, concrete circumstances surrounding decisions to use requirements engineering methods were investigated. This paper reports the results of the analyses and discusses changes in the planning and management of clinical decision-support projects in general, and it comments on development methods, using Action Design as reference. It is concluded that studies are needed to further investigate the problems real decision-support projects have to deal with. This knowledge can then be used to develop methods and tools which support design practices where existing structural, procedural and, building on this, technical obstacles are overcome.
最近有人指出，临床决策支持系统开发中存在需求分析不足的问题。因此，为了探究知识、实践和态度，来自四个国家的该领域关键专业人士就开发过程的早期阶段接受了访谈。为了收集数据，进行了半结构化访谈并录像。作为参考，使用了行动设计需求工程方法的文档。对数据进行了两项独立的定性分析。第一项是确定与需求工程相关的核心概念和态度。在第二项分析中，调查了使用需求工程方法决策所围绕的具体情况。本文报告了分析结果，讨论了一般临床决策支持项目规划和管理中的变化，并以行动设计为参考对开发方法进行了评论。得出的结论是，需要开展研究以进一步调查实际决策支持项目必须应对的问题。然后，这些知识可用于开发方法和工具，以支持在克服现有结构、程序以及在此基础上的技术障碍的设计实践。
