摘要

背景:icu常规收集的数据量不断增加,给临床医生带来了挑战,而持续肾脏替代疗法(CKRT)等数据繁重的治疗方法则加剧了这一挑战。我们开发了CKRT支持软件原型(CKRT- ssp),这是一个用于CKRT之前,期间和之后的临床决策支持系统。这项用户体验(UX)研究的目的是前瞻性地评估CKRT-SSP在模拟ICU环境下的可用性、用户体验和工作量。方法:我们在ICU设备齐全的单人病房模拟CKRT治疗,并使用有效的问卷:系统可用性量表(SUS)和用户体验问卷(UEQ)评估CKRT- ssp。此外,采用改进的NASA-TLX(任务负荷指数)比较了使用CKRT-SSP前后的工作负荷。12名临床医生和护士参与了这项研究。结果:CKRT-SSP的SUS达到了87.5的中位值,反映了良好的可用性。在UEQ中,CKRT-SSP在吸引力维度和三个与任务相关的维度(清晰度、效率和可靠性)上得分明显为正(95% CI完全为0.0.8)。对于非任务相关的两个维度,刺激和新颖性,有积极的趋势(平均> 0.8,95% CI下限)。结论:CKRT- ssp是改善icu工作量和CKRT具体应用的有希望的工具。我们获得了进一步以用户为中心的开发的宝贵见解。

User experience study to evaluate a clinical decision support system prototype supporting continuous kidney replacement therapy in a simulated ICU environment.

User experience study to evaluate a clinical decision support system prototype supporting continuous kidney replacement therapy in a simulated ICU environment.

Background: The increasing amount of data routinely collected on ICUs poses a challenge for clinicians which is aggravated with data-heavy therapies like Continuous Kidney Replacement Therapy (CKRT). We developed the CKRT Supporting Software Prototype (CKRT-SSP), a clinical decision support system for use before, during and after CKRT. The aim of this user experience (UX) study was to prospectively evaluate CKRT-SSP in terms of usability, user experience, and workload in a simulated ICU setting.

Methods: We simulated CKRT treatments in a fully equipped single patient room in the ICU and evaluated CKRT-SSP using validated questionnaires: System Usability Scale (SUS) and User Experience Questionnaire (UEQ). Furthermore, a modified NASA-TLX (task load index) compared the workload before and after using CKRT-SSP. Twelve clinicians and nurses participated in this study.

Results: The SUS reached a median value of 87.5 for CKRT-SSP, reflecting excellent usability. In the UEQ, CKRT-SSP scored clearly positive in the attractiveness dimension and the three task-related dimensions of clarity, efficiency, and dependability (95% CI fully > 0.8). For the two non-task-related dimensions, stimulation and novelty, there was a positive trend (mean > 0.8, lower limit of 95% CI < 0.8). The modified NASA-TLX suggests a trend to less total workload with CKRT-SSP which mainly is attributable to less physical demand and less effort.

Conclusion: CKRT-SSP is a promising tool for improving the workload in ICUs and the specific application of CKRT. We obtained valuable insights for further user-centric development.
