Patient order management (POM) is a mission-critical task for perioperative workflow. Interface complexity within different EHR systems result in poor usability, increasing documentation burden. POM interfaces were compared across two systems prior to (Cerner SurgiNet) and subsequent to an EHR conversion (Epic). Here we employ a navigational complexity framework useful for examining differences in EHR interface systems. The methodological approach includes 1) expert-based methods-specifically, functional analysis, keystroke level model (KLM) and cognitive walkthrough, and 2) quantitative analysis of observed interactive user behaviors. We found differences in relation to navigational complexity with the SurgiNet interface displaying a higher number of unused POM functions, with 12 in total whereas Epic displayed 7 total functions. As reflected in all measures, Epic facilitated a more streamlined task-focused user experience. The approach enabled us to scrutinize the impact of different EHR interfaces on task performance and usability barriers subsequent to system implementation.
患者医嘱管理（POM）是围手术期工作流程中的一项关键任务。不同电子健康记录（EHR）系统之间的接口复杂性导致可用性差，增加了文档负担。在电子健康记录转换之前（Cerner SurgiNet）和之后（Epic），对两个系统的POM接口进行了比较。在这里，我们采用了一个导航复杂性框架，该框架有助于检查电子健康记录接口系统中的差异。方法包括：1）基于专家的方法，具体来说是功能分析、按键级模型（KLM）和认知走查；2）对观察到的用户交互行为进行定量分析。我们发现，在导航复杂性方面存在差异，SurgiNet接口显示出更多未使用的POM功能，总共12个，而Epic总共显示7个功能。正如所有指标所反映的那样，Epic提供了更简化的以任务为中心的用户体验。该方法使我们能够在系统实施后仔细审查不同电子健康记录接口对任务性能和可用性障碍的影响。
