With the rising use of patient-reported outcomes (PRO) in clinical practice, there is an increasing need to understand the data visualization needs of clinical teams to support their effective use of PRO data for both individual patient decision making and broader population health applications. A human-centered design (HCD) approach can optimize the visual design of an interactive PRO system.
Recent literature regarding the use of HCD to design and develop PRO visualizations demonstrates the benefits of iterative methods that engage representative users who are likely to use the system in the future. However, the literature has not explored the additive value of other HCD methods such as heuristic evaluation, which involves expert examination of the interface with respect to recognized usability principles, the heuristics.
Our experience in using heuristic evaluation to enhance the design of a PRO dashboard led to several recommendations to improve the display, accessibility, and interpretability of the dashboard's data. Heuristic evaluation can serve as a complement to HCD methods that directly engage users and thereby enhance usability.
随着患者报告结局（PRO）在临床实践中的使用日益增加，越来越需要了解临床团队的数据可视化需求，以支持他们有效地使用PRO数据进行个体患者决策和更广泛的人群健康应用。以人为本的设计（HCD）方法可以优化交互式PRO系统的视觉设计。
在HCD工具箱中纳入启发式评估：最近关于使用HCD设计和开发PRO可视化的文献表明了迭代方法的好处，这些方法让未来可能使用该系统的代表性用户参与进来。然而，文献尚未探讨其他HCD方法的附加价值，如启发式评估，它涉及根据公认的可用性原则（即启发式方法）对界面进行专家审查。
我们使用启发式评估来改进PRO仪表板设计的经验产生了一些建议，以改善仪表板数据的显示、可访问性和可解释性。启发式评估可以作为直接让用户参与的HCD方法的补充，从而提高可用性。
