HCI Evaluation of Medication Use HITs in Pediatric Care

描述(由申请人提供)：基于药物的差错已经成为医疗保健，特别是儿科护理中的首要问题。这些基本上可以预防的错误每年在美国导致数千人死亡，甚至更多的受伤、并发症和成本。因此，人们对用于药物管理实践的健康信息技术(HITS)产生了相当大的兴趣。然而，这些系统中的许多在实践中都失败了，这可以归因于这些系统没有适当地设计来支持用户在考虑其工作环境的情况下执行其实际工作。这些问题代表了人机交互(HCI)研究的主要重点，它认识到考虑人类用户和IT系统之间交互的所有方面的重要性。这项研究与亚特兰大儿童保健(Choa)合作，旨在研究在儿科护理中执行药物管理任务时，影响用户与传统和移动计算技术交互的基于用户、设备和环境的因素。这篇论文研究提出了一项研究，将包括90名临床参与者在Choa的医疗保健环境中使用构建的HIT系统执行药物管理过程(例如，患者记录访问、订单输入、临床文档)的基本交互任务(例如，文本输入、项目选择、与控制交互)。将使用完全析因设计(3x3x2)来探索IT设备平台、用户类型和任务复杂性的变化对任务绩效和用户体验测量的影响。这项研究的结果将作为在大型儿科医院明智地设计、开发和实施HITS的经验证据基础，这将有助于确保这些系统在实践中可用和有效。这项研究实现了AHRQ/DHHS的研究目标和优先人群倡议，因为这项研究侧重于改善儿科护理环境中的医疗差错/患者安全，以及TRIPP倡议。

DESCRIPTION (provided by applicant): Medication-based errors have become a paramount issue in health care, especially pediatric care. These largely preventable errors result in thousands of deaths, and even more injuries, complications and costs, in the United States each year. As a result, there has been considerable interest in health information technologies (HITs) designed for medication management practices. However, many of these systems have failed in practice, which can be attributed to these systems not being appropriately designed to support users performing their actual work with considerations for their working context of work. These issues represent a primary focus of research in human-computer interaction (HCI), which recognizes the importance of considering all facets of interaction between human users and IT systems. In collaboration with Children's Healthcare of Atlanta (CHOA), this research aims to examine user-, device- and context-based factors that affect user interaction with traditional and mobile computing technologies while performing medication management tasks in pediatric care. This dissertation research proposes a study that will involve 90 clinical participants in a healthcare setting at CHOA performing fundamental interaction tasks (e.g., text entry, item selection, interacting with controls) of medication management processes (e.g., patient record access, order entry, clinical documentation) using a constructed HIT system. A full factorial design (3x3x2) will be used to explore the impact of changes in IT device platform, user type, and task complexity on measures of task performance and user experience. The results of this study will serve as a foundation of empirical evidence for the judicious design, development and implementation of HITs in large-scale pediatric hospitals, which will help ensure that these systems are usable and effective in practice. This dissertation research fulfills the research objectives and priority population initiatives of AHRQ/DHHS, as this study focuses on improving medical errors/patient safety in pediatric care environments, as well as the TRIPP initiative.
