The task of monitoring and managing the entire emergency department (ED) is becoming more important due to increasing pressure on the ED. Recently, dashboards have received the spotlight as health information technology to support these tasks.
This study aimed to describe the development of a real-time autonomous dashboard for the ED and to evaluate perspectives of clinical staff on its usability.
We developed a dashboard based on three principles-"anytime, anywhere, at a glance;" "minimal interruption to workflow;" and "protect patient privacy"-and 3 design features-"geographical layout," "patient-level alert," and "real-time summary data." Items to evaluate the dashboard were selected based on the throughput factor of the conceptual model of ED crowding. Moreover, ED physicians and nurses were surveyed using the system usability scale (SUS) and situation awareness index as well as a questionnaire we created on the basis of the construct of the Situation Awareness Rating Technique.
The first version of the ED dashboard was successfully launched in 2013, and it has undergone 3 major revisions since then because of geographical changes in ED and modifications to improve usability. A total of 52 ED staff members participated in the survey. The average SUS score of the dashboard was 67.6 points, which indicates "OK-to-Good" usability. The participants also reported that the dashboard provided efficient "concentration support" (4.15 points), "complexity representation" (4.02 points), "variability representation" (3.96 points), "information quality" (3.94 points), and "familiarity" (3.94 points). However, the "division of attention" was rated at 2.25 points.
We developed a real-time autonomous ED dashboard and successfully used it for 5 years with good evaluation from users.
由于急诊科压力不断增加，监测和管理整个急诊科的任务变得越发重要。近来，仪表板作为支持这些任务的健康信息技术受到了关注。
本研究旨在描述一种用于急诊科的实时自主仪表板的开发过程，并评估临床工作人员对其可用性的看法。
我们基于三条原则——“随时随地，一目了然”；“对工作流程干扰最小”；以及“保护患者隐私”——和三个设计特点——“地理布局”、“患者级警报”和“实时汇总数据”开发了一个仪表板。根据急诊科拥挤概念模型的吞吐量因素选择了评估仪表板的项目。此外，还使用系统可用性量表（SUS）、态势感知指数以及我们根据态势感知评级技术的结构创建的问卷对急诊科医生和护士进行了调查。
急诊科仪表板的第一个版本于2013年成功推出，此后由于急诊科的地理变化以及为提高可用性而进行的修改，它经历了3次重大修订。共有52名急诊科工作人员参与了调查。仪表板的平均SUS得分为67.6分，表明其可用性为“尚可至良好”。参与者还报告称，该仪表板提供了高效的“注意力支持”（4.15分）、“复杂性呈现”（4.02分）、“变异性呈现”（3.96分）、“信息质量”（3.94分）和“熟悉度”（3.94分）。然而，“注意力分散”的评分为2.25分。
我们开发了一种实时自主的急诊科仪表板，并成功使用了5年，得到了用户的良好评价。
