We explore relationships between barriers and facilitators experienced by users to understand dynamic interactions in sociotechnical systems and improve a mobile phone-based augmented reality application that teaches users about the contents of a standardized pediatric code cart.
Understanding interactions between performance obstacles and facilitators can provide guidance to (re)designing sociotechnical systems to improve system outcomes. Clinicians should know about contents and organization of code carts, and an augmented reality mobile application may improve that knowledge but changes the sociotechnical system in which they learn. Prior work identified barriers and facilitators impacting the use of this application-participants described dimensions together, indicating interactions that are explored in the current study.
We conducted four focus groups (number of clinicians = 18) and two interviews with clinicians who used the application. We performed a secondary analysis of focus group data exploring interactions between previously identified barriers and facilitators to application use. We used epistemic network analysis to visualize these interactions.
Work system barriers interacted with barriers and facilitators interacted with facilitators to amplify cumulative negative or positive impact, respectively. Facilitators balanced barriers, mitigating negative impact. Facilitators also exacerbated barriers, worsening negative impact.
Barriers and facilitators interact and can amplify, balance, and exacerbate each other-notably, positives are not always positive. To obtain desired outcomes, interactions must be further considered in sociotechnical system design, for example, the potential improvements to the application we identified.
我们探讨用户所经历的障碍与促进因素之间的关系,以了解社会技术系统中的动态交互,并改进一款基于手机的增强现实应用程序,该程序用于向用户传授标准化儿科急救推车的内容。
了解性能障碍与促进因素之间的相互作用可为(重新)设计社会技术系统以改善系统结果提供指导。临床医生应了解急救推车的内容和组织情况,而一款增强现实移动应用程序可能会提高这方面的知识,但会改变他们学习的社会技术系统。先前的研究确定了影响该应用程序使用的障碍和促进因素——参与者共同描述了各个维度,表明了当前研究中所探讨的相互作用。
我们进行了四个焦点小组讨论(临床医生数量 = 18),并对使用该应用程序的临床医生进行了两次访谈。我们对焦点小组数据进行了二次分析,探讨先前确定的应用程序使用障碍与促进因素之间的相互作用。我们使用认知网络分析来可视化这些相互作用。
工作系统障碍与障碍相互作用,促进因素与促进因素相互作用,分别放大累积的负面影响或正面影响。促进因素平衡了障碍,减轻了负面影响。促进因素也加剧了障碍,使负面影响恶化。
障碍和促进因素相互作用,且可以相互放大、平衡和加剧——值得注意的是,积极因素并不总是积极的。为了获得期望的结果,在社会技术系统设计中必须进一步考虑相互作用,例如,我们所确定的对该应用程序的潜在改进。
