This paper reports the process by which a personalized cancer treatment system was built, following a user-centered approach. We give some background on personalized cancer treatment, the particular tumor chemosensitivity assay supported by the system, as well as some quality and legal issues related to such health systems. We describe how Contextual Design was applied when building the system. Contextual design is a user-centered design technique involving seven steps. We also provide some details about the system implementation. Finally, we explain how the Think-Aloud protocol and Heuristic Evaluation methods were used to evaluate the system and report its results. A qualitative assessment from the users perspective is also provided. Results from the heuristic evaluation indicate that only one of ten heuristics was missing from the system, while five were partially covered and four were fully covered.
本文报告了一种以用户为中心的方法构建个性化癌症治疗系统的过程。我们介绍了个性化癌症治疗的一些背景、该系统支持的特定肿瘤化学敏感性测定，以及与这类健康系统相关的一些质量和法律问题。我们描述了在构建系统时如何应用情境设计。情境设计是一种以用户为中心的设计技术，包括七个步骤。我们还提供了有关系统实施的一些细节。最后，我们解释了如何使用出声思考协议和启发式评估方法来评估系统并报告其结果。还提供了从用户角度进行的定性评估。启发式评估的结果表明，该系统仅缺少十条启发式规则中的一条，五条部分涵盖，四条完全涵盖。
