To describe nurses' preferences for the design of a probability-based clinical decision support (PB-CDS) tool for in-hospital clinical deterioration.
A convenience sample of bedside nurses, charge nurses, and rapid response nurses (n = 20) from adult and pediatric hospitals completed participatory design sessions with researchers in a simulation laboratory to elicit preferred design considerations for a PB-CDS tool. Following theme-based content analysis, we shared findings with user interface designers and created a low-fidelity prototype.
Three major themes and several considerations for design elements of a PB-CDS tool surfaced from end users. Themes focused on "painting a picture" of the patient condition over time, promoting empowerment, and aligning probability information with what a nurse already believes about the patient. The most notable design element consideration included visualizing a temporal trend of the predicted probability of the outcome along with user-selected overlapping depictions of vital signs, laboratory values, and outcome-related treatments and interventions. Participants expressed that the prototype adequately operationalized requests from the design sessions.
Participatory design served as a valuable method in taking the first step toward developing PB-CDS tools for nurses. This information about preferred design elements of tools that support, rather than interrupt, nurses' cognitive workflows can benefit future studies in this field as well as nurses' practice.
描述护士对于用于医院内临床病情恶化的基于概率的临床决策支持(PB-CDS)工具设计的偏好。
从成人及儿科医院抽取的包括床边护士、护士长和快速反应护士在内的便利样本(n = 20),与研究人员在模拟实验室完成了参与式设计环节,以得出PB-CDS工具的首选设计考量因素。在进行基于主题的内容分析后,我们与用户界面设计师分享了研究结果,并创建了一个低保真原型。
终端用户提出了PB-CDS工具设计元素的三大主要主题及若干考量因素。这些主题聚焦于随时间“描绘”患者病情状况、促进自主性以及使概率信息与护士对患者已有的认知相一致。最值得注意的设计元素考量包括可视化结果预测概率的时间趋势,以及用户选择的生命体征、实验室值和与结果相关的治疗及干预措施的重叠描绘。参与者表示该原型充分实现了设计环节提出的要求。
参与式设计是朝着为护士开发PB-CDS工具迈出第一步的宝贵方法。这些关于支持而非打断护士认知工作流程的工具首选设计元素的信息,可使该领域未来的研究以及护士的实践受益。
