过度使用抗生素是当今重症监护中的一个严重问题。由于临床数据呈现在分布式的、通常是独立的信息系统中，数据密集的环境使情况进一步复杂化。访问和解释所有数据是一项复杂且耗时的技术和认知挑战。我们建议以患者概述的形式进行整体集成可视化，以支持医生在重症监护病房使用抗生素的决策。特别强调分析工作流程以识别信息需求，开发基于集成数据模型的可视化工具，以及结合眼动追踪技术对该工具进行可用性测试。可视化工具在用户性能和偏好方面获得了很高的评价，对用户视觉模式的分析表明，根据要执行的任务，不同类型的数据可视化可能使专科医生和住院重症监护医生受益。一种高度互动的综合信息可视化工具可能会增加对患者感染状况的了解，并最终提高抗生素使用的决策。
Overuse of antibiotics is a critical problem in intensive care today. The situation is further complicated by the extremely data-intensive environment with clinical data presented in distributed, often stand-alone information systems. To access and interpret all data is a complex and time-consuming technical and cognitive challenge. We propose a holistic integrated visualization in the form of a patient overview to support physicians in decision making for use of antibiotics at intensive care units. Special emphasis is put on analysis of work processes to identify information needs, the development of a visualization tool based on an integrated data model, and usability testing of the tool in combination with an eye-tracking technology. The visualization tool was highly rated in terms of user performance and preferences, and the analysis of users' visual patterns showed that different types of data visualization may benefit specialist and resident intensive care physicians depending on the task to be performed. A highly interactive tool for integrated information visualization could potentially increase the understanding of a patient's infection status and ultimately enhance decision making for the use of antibiotics.
