本研究的目的是评估ICU护士使用综合图形信息显示（IGID）与传统表格ICU患者信息显示（即电子图表）检测患者变化的能力。使用来自两个不同地点的参与者，我们进行了一项基于重复测量模拟器的实验，以评估ICU护士使用新型IGID与传统表格信息显示检测异常患者变量的能力。患者场景和显示演示完全平衡。我们测量了异常患者变量、护士感知工作量（NASA-TLX）和显示可用性评分的正确率。32名ICU护士（87%为女性，中位年龄29岁，中位ICU工作经验2.5年）使用IGID检测到的异常变量多于表格显示[F (1,119)=13.0, p < 0.05]。场地的主效应显著[F(1,119)=14.2]，开发场地的参与者表现更好。护士的感知工作量无显著差异。IGID显示器被评为比传统显示器更有用，[F(1,60)=31.7]。总体而言，与表格显示相比，护士报告了更重要的生理信息。此外，场地差异的发现可能反映了工作实践中的地方影响和参与迭代展示设计方法。使用以用户为中心的设计开发的信息显示应该适应不同使用站点的预期用户群体的全部多样性。
The purpose of this study was to evaluate ICU nurses’ ability to detect patient change using an integrated graphical information display (IGID) versus a conventional tabular ICU patient information display (i.e. electronic chart). Using participants from two different sites, we conducted a repeated measures simulator-based experiment to assess ICU nurses’ ability to detect abnormal patient variables using a novel IGID versus a conventional tabular information display. Patient scenarios and display presentations were fully counterbalanced. We measured percent correct detection of abnormal patient variables, nurses’ perceived workload (NASA-TLX), and display usability ratings. 32 ICU nurses (87% female, median age of 29 years, and median ICU experience of 2.5 years) using the IGID detected more abnormal variables compared to the tabular display [F (1,119)=13.0, p < 0.05]. There was a significant main effect of site [F (1, 119)=14.2], with development site participants doing better. There were no significant differences in nurses’ perceived workload. The IGID display was rated as more usable than the conventional display, [F (1, 60)=31.7]. Overall, nurses reported more important physiological information with the novel IGID than tabular display. Moreover, the finding of site differences may reflect local influences in work practice and involvement in iterative display design methodology. Information displays developed using user-centered design should accommodate the full diversity of the intended user population across use sites.
