The term "usability" describes how effectively, efficiently, and with what level of user satisfaction an information system can be used to accomplish specific goals. Computerized critical care information systems (CCISs) with high usability increase quality of care and staff satisfaction, while reducing medication errors. Conversely, systems lacking usability can interrupt clinical workflow, facilitate errors, and increase charting time. The aim of this study was to investigate and compare usability across CCIS currently used in Germany.
In this study, German intensive care unit (ICU) nurses and physicians completed a specialized, previously validated, web-based questionnaire. The questionnaire assessed CCIS usability based on three rating models: an overall rating of the systems, a model rating technical usability, and a model rating task-specific usability.
We analyzed results from 535 survey participants and compared eight different CCIS commonly used in Germany. Our results showed that usability strongly differs across the compared systems. The system ICUData had the best overall rating and technical usability, followed by the platforms ICM and MetaVision. The same three systems performed best in the rating of task-specific usability without significant differences between each other. Across all systems, overall ratings were more dependent on ease-of-use aspects than on aspects of utility/functionality, and the general scope of the functions offered was rated better than how well the functions are realized.
Our results suggest that manufacturers should shift some of their effort away from the development of new features and focus more on improving the ease-of-use and quality of existing features.
“可用性”一词描述了信息系统在完成特定目标时的有效性、效率和用户满意度。具有高可用性的计算机化重症监护信息系统 (CCIS) 可以提高护理质量和员工满意度，同时减少用药错误。相反，缺乏可用性的系统会中断临床工作流程，促进错误，并增加图表时间。本研究旨在调查和比较德国目前使用的 CCIS 的可用性。
在这项研究中，德国重症监护病房 (ICU) 的护士和医生完成了一项专门的、先前经过验证的基于网络的问卷。该问卷根据三个评分模型评估 CCIS 的可用性：系统的整体评分、技术可用性评分模型和任务特定可用性评分模型。
我们分析了 535 名调查参与者的结果，并比较了德国常用的八种不同的 CCIS。我们的结果表明，可用性在比较的系统之间存在很大差异。系统 ICUData 的整体评分和技术可用性最好，其次是 ICM 和 MetaVision 平台。这三个相同的系统在特定任务的可用性评分中表现最好，彼此之间没有显着差异。在所有系统中，整体评分更依赖于易用性方面，而不是实用性/功能方面，并且提供的功能的总体范围比功能的实现情况要好。
我们的结果表明，制造商应将部分精力从开发新功能转移到改进现有功能的易用性和质量上。
