Integrated care pathways (ICPs) define a chronological sequence of steps, most commonly diagnostic or treatment, to be followed in providing care for patients. Care pathways help to ensure quality standards are met and to reduce variation in practice. Although research on the computerisation of ICP progresses, there is still little knowledge on what are the requirements for designing user-friendly and usable electronic care pathways, or how users (normally health care professionals) interact with interfaces that support design, analysis and visualisation of ICPs. The purpose of the study reported in this paper was to address this gap by evaluating the usability of a novel web-based tool called COCPIT (Collaborative Online Care Pathway Investigation Tool). COCPIT supports the design, analysis and visualisation of ICPs at the population level. In order to address the aim of this study, an evaluation methodology was designed based on heuristic evaluations and a mixed method usability test. The results showed that modular visualisation and direct manipulation of information related to the design and analysis of ICPs is useful for engaging and stimulating users. However, designers should pay attention to issues related to the visibility of the system status and the match between the system and the real world, especially in relation to the display of statistical information about care pathways and the editing of clinical information within a care pathway. The paper concludes with recommendations for interface design.
综合护理路径 (ICPs) 定义了为患者提供护理时要遵循的时间顺序步骤，这些步骤通常是诊断或治疗。护理路径有助于确保满足质量标准，并减少实践中的差异。尽管 ICP 的计算机化研究不断取得进展，但对于设计用户友好且可用的电子护理路径的要求，以及用户（通常是医疗保健专业人员）如何与支持 ICP 设计、分析和可视化的界面进行交互，仍然知之甚少。本文报道的研究旨在通过评估一种名为 COCPIT（协作在线护理路径调查工具）的新型基于网络的工具的可用性来弥补这一空白。COCPIT 支持在人群水平上设计、分析和可视化 ICP。为了实现本研究的目的，设计了一种基于启发式评估和混合方法可用性测试的评估方法。结果表明，模块化可视化和直接操作与 ICP 设计和分析相关的信息对于吸引和激发用户很有用。但是，设计人员应该注意与系统状态可见性和系统与现实世界之间的匹配相关的问题，特别是在与护理路径的统计信息显示和护理路径内的临床信息编辑相关的问题。本文最后提出了界面设计的建议。
