HCI Evaluation of Medication Use HITs in Pediatric Care

描述（由申请人提供）：基于药物的错误已成为医疗保健，特别是儿科护理的首要问题。在美国，这些基本上可以预防的错误每年导致数千人死亡，甚至更多的伤害，并发症和成本。因此，有相当大的兴趣在医疗信息技术（HIT）设计的药物管理实践。然而，这些系统中有许多在实践中失败了，这可以归因于这些系统没有被适当地设计成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）研究的主要焦点，它认识到考虑人类用户和IT系统之间交互的各个方面的重要性。与亚特兰大儿童医疗保健（CHOA）合作，本研究旨在研究影响用户与传统和移动的计算技术的交互的基于用户、设备和上下文的因素，同时在儿科护理中执行药物管理任务。本论文的研究提出了一项研究，将涉及90名临床参与者在医疗保健设置在CHOA执行基本的互动任务（例如，文本输入、项目选择、与控制交互）的药物管理过程（例如，患者记录访问、订单输入、临床文档）使用构建的HIT系统。将使用全析因设计（3x 3x 2）探索IT设备平台、用户类型和任务复杂性的变化对任务性能和用户体验指标的影响。本研究的结果将作为经验证据的基础，为明智的设计，开发和实施的HIT在大型儿科医院，这将有助于确保这些系统是可用的，有效的实践。本论文研究实现了AHRQ/DHHS的研究目标和优先人口计划，因为本研究的重点是改善儿科护理环境中的医疗错误/患者安全，以及TRIPP计划。

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.
