Data collection, in high intensity environments, poses several challenges including the ability to observe multiple streams of information. These problems are especially evident in critical care, where monitoring of the Advanced Trauma Life Support (ATLS) protocol provides an excellent opportunity to study the efficacy of applications that allow for the rapid capture of event information, providing theoretically-driven feedback using the data. Our goal was, (a) to design and implement a way to capture data on deviation from the standard practice based on the theoretical foundation of error classification from our past research, (b) to provide a means to meaningfully visualize the collected data, and (c) to provide a proof-of-concept for this implementation, using some understanding of user experience in clinical practice.
We present the design and development of a web application designed to be used primarily on mobile devices and a summary data viewer to allow clinicians to, (a) track their activities, (b) provide real-time feedback of deviations from guidelines and protocols, and (c) provide summary feedback highlighting decisions made. We used a framework previously developed to classify activities in trauma as the theoretical foundation of the rules designed to do the same algorithmically, in our application. Attending physicians at a Level 1 trauma center used the application in the clinical setting and provided feedback for iterative development. Informal interviews and surveys were used to gain some deeper understanding of the user experience using this application in-situ.
Activity visualizations were created highlighting decisions made during a trauma code as well as classification of tasks per the theoretical framework. The attendings reviewed the efficacy of the data visualizations as part of their interviews. We also conducted a proof-of-concept evaluation by way of usability questionnaire. Two attendings rated 4 out of the usability 6 categories highly (inter-rater reliability: R = 0.87; weighted kappa = 0.59). This could be attributed to the fact that they were able to fit the use of the application into their regular workflow during a trauma code relatively seamlessly. A deeper evaluation is required to answer explain this further.
Our application can be used to capture and present data to provide an accurate reflection of work activities in real-time in complex critical care environments, without any significant interruptions to workflow.
在高强度环境中进行数据收集面临诸多挑战,包括观察多信息流的能力。这些问题在重症监护中尤为明显,对高级创伤生命支持(ATLS)协议的监测为研究允许快速获取事件信息的应用程序的功效提供了绝佳机会,并利用这些数据提供理论驱动的反馈。我们的目标是:(a)基于我们过去研究中的错误分类理论基础,设计并实现一种方法来捕获偏离标准实践的数据;(b)提供一种有意义地可视化收集到的数据的手段;(c)利用对临床实践中用户体验的一些理解,为这种实现提供概念验证。
我们展示了一个主要设计用于移动设备的网络应用程序以及一个汇总数据查看器的设计与开发,使临床医生能够:(a)跟踪他们的活动;(b)提供与指南和协议偏差的实时反馈;(c)提供突出所做决策的汇总反馈。我们使用先前开发的一个将创伤中的活动进行分类的框架,作为我们应用程序中设计用于以算法方式执行相同操作的规则的理论基础。一级创伤中心的主治医生在临床环境中使用该应用程序,并为迭代开发提供反馈。通过非正式访谈和调查,以更深入地了解在现场使用此应用程序的用户体验。
创建了活动可视化,突出显示了创伤急救期间所做的决策以及根据理论框架对任务的分类。主治医生在访谈中审查了数据可视化的功效。我们还通过可用性问卷进行了概念验证评估。两名主治医生对可用性6个类别中的4个给予了高度评价(评分者间信度:R = 0.87;加权kappa = 0.59)。这可能归因于他们能够在创伤急救期间相对无缝地将应用程序的使用融入其常规工作流程。需要进行更深入的评估以进一步解释这一点。
我们的应用程序可用于捕获和呈现数据,以在复杂的重症监护环境中实时准确反映工作活动,且不会对工作流程造成任何重大干扰。
