The paper presents results from a design research project of a user interface (UI) for a Computerised Clinical Decision Support System (CDSS). The ambition has been to design Human-Computer Interaction (HCI) that can minimise medication errors. Through an iterative design process a digital prototype for prescription of medicine has been developed. This paper presents results from the formative evaluation of the prototype conducted in a simulation laboratory with ten participating physicians. Data from the simulation is analysed by use of theory on how users perceive information. The conclusion is a model, which sum up four principles of interaction for design of CDSS. The four principles for design of user interfaces for CDSS are summarised as four A's: All in one, At a glance, At hand and Attention. The model emphasises integration of all four interaction principles in the design of user interfaces for CDSS, i.e. the model is an integrated model which we suggest as a guide for interaction design when working with preventing medication errors.
本文展示了一个针对计算机化临床决策支持系统（CDSS）用户界面（UI）的设计研究项目的成果。其目标是设计出能够将用药错误降至最低的人机交互（HCI）方式。通过迭代设计过程，开发出了一个用于药物处方的数字原型。本文展示了在模拟实验室中对该原型进行的形成性评估结果，有十位参与的医生参与了评估。利用关于用户如何感知信息的理论对模拟数据进行了分析。得出的结论是一个模型，该模型总结了CDSS设计的四个交互原则。CDSS用户界面设计的四个原则概括为四个“A”：一体化（All in one）、一目了然（At a glance）、随手可得（At hand）和引人注意（Attention）。该模型强调在CDSS用户界面设计中整合所有这四个交互原则，即该模型是一个综合模型，我们建议在致力于预防用药错误时将其作为交互设计的指南。
