Electronic health records have often been criticized for poor interaction design. One major problem is the 'display fragmentation problem' i.e. the fact that conventional EHRs require the user to view many screens and retain information in memory or external tools rather than being able to view all relevant information together, increasing cognitive load and the possibility of errors and inefficiency. We describe a method for evaluating and depicting the extent of display fragmentation and discuss its potential uses in comparing systems, identifying navigation pathways and information juxtaposition, and improving EHR interaction design.
电子健康记录常常因交互设计不佳而受到批评。一个主要问题是“显示碎片化问题”，即传统电子健康记录要求用户查看多个屏幕并在内存或外部工具中保留信息，而不是能够一起查看所有相关信息，这增加了认知负担以及出错和效率低下的可能性。我们描述了一种评估和描述显示碎片化程度的方法，并讨论了其在比较系统、识别导航路径和信息并列以及改进电子健康记录交互设计方面的潜在用途。
