尽管图形用户界面(GUI)在医疗保健中被普遍采用，但很少有经验数据记录这一举措对系统用户的影响。本研究比较了两种截然不同的用户界面，传统的基于文本的界面和原型图形界面，比较了在执行计算机化护理订单任务时护士的反应时间(RT)、错误和满意度的差异。在美国东海岸的一家医疗中心，98名随机选择的男女护士分别使用每个界面完成了40项任务。护士完成了四种不同类型的订单任务(创建、激活、修改和终止)。使用重复测量和拉丁方设计，这项研究在任务、界面类型和试验区块方面取得了平衡。总体而言，护士使用原型图形用户界面的反应时间(P<；0.0001)和错误(P<；0.0001)明显快于基于文本的界面。图形用户界面的满意度也明显高于文本系统，而且学习起来更快(P<；0.0001)。因此，结果表明，使用护理订单的原型图形用户界面显著提高了用户性能和满意度。应该考虑重新设计旧的用户界面，通过使用人的因素、原则和来自以用户为中心的焦点小组的意见来创建更现代的用户界面。未来的工作应该检查基于计算机的患者记录中高度复杂的交互作用的预期护理界面，详细说明在线错误的严重性，并探索优化生命关键系统中交互作用的设计。
Despite the general adoption of graphical users interfaces (GUIs) in health care, few empirical data document the impact of this move on system users. This study compares two distinctly different user interfaces, a legacy text-based interface and a prototype graphical interface, for differences in nurses' response time (RT), errors, and satisfaction when the interfaces are used in the performance of computerized nursing order tasks. In a medical center on the East Coast of the United States, 98 randomly selected male and female nurses completed 40 tasks using each interface. Nurses completed four different types of order tasks (create, activate, modify, and discontinue). Using a repeated-measures and Latin square design, the study was counterbalanced for tasks, interface types, and blocks of trials. Overall, nurses had significantly faster response times (P < 0.0001) and fewer errors (P < 0.0001) using the prototype GUI than the text-based interface. The GUI was also rated significantly higher for satisfaction than the text system, and the GUI was faster to leam (P < 0.0001). Therefore, the results indicated that the use of a prototype GUI for nursing orders significantly enhances user performance and satisfaction. Consideration should be given to redesigning older user interfaces to create more modern ones by using human factors principles and input from user-centered focus groups. Future work should examine prospective nursing interfaces for highly complex interactions in computer-based patient records, detail the severity of errors made on line, and explore designs to optimize interactions in life-critical systems.
