MediMatrix: An Interface for Visualizing Learner-Generated Patient Case Collections in Postgraduate Medical Training

摘要

This paper presents a visualization approach to accessing and exploring the knowledge obtained from patient cases created by general practitioners in their medical practice during postgraduate practical training. Our application MediMatrix visualizes this knowledge base by displaying the patient cases in a matrix-based grid. It addresses domain specific challenges (broad spectrum of medical topics, isolation from peers during training, time pressure) and use cases (solving patient cases, learning for the exam) of the target group. In addressing these requirements MediMatrix focuses on supporting specific kinds of information tasks such as gaining a quick overview of a heterogeneous case collection, comparing a specific case with other cases and discovering topical cross-connections between cases. Through the provided visual modalities for explorative access of a learner-generated medical case collection physicians can easily discover patient cases relevant for their practice and share knowledge by discussing, working on and learning from the patient cases.
