description
CareVis is an interactive visualization tool designed to support protocol-based care.

CareVis provides multiple views simultaneously on the screen of different aspects of the complex underlying data structure of treatment plans and patient data. It is designed for use, for example, during guideline execution. CareVis employs a visualization technique called AsbruFlow, based on the idea of a flowchart-like clinical algorithm. The concept has been extended to depict the characteristics of a treatment plan formulated in the plan specification language Asbru. CareVis supports navigation, provides annotations and helps maintain orientation by using focus+context techniques, thus increasing the flexibility in working with treatment plans and patient data.

CareVis provides three types of views (see figure 1 below):
  • The QuickView Panel displays the most important patient parameters and plan variables
  • The Logical View shows treatment plans in terms of their logical structure (hierarchical decomposition, plan elements, execution order, conditions).
  • The Temporal View naturally focuses on the temporal aspects of treatment plans and measured patient data as well as plan variables (temporal aspects of plan elements, temporal uncertainties, hierarchical decomposition). The temporal representation of treatment plans is based on the idea of LifeLines, a concept that has been extended to display hierarchical decomposition (LifeLines+)as well as the complex time annotations used in Asbru (PlanningLines).

" Currently, visualization support for patient data analysis is mostly limited to the representation of directly measured data. Contextual information on performed treatment steps is an important source for finding reasons and explanations for certain phenomena in the measured patient data. But this kind of information is mostly spared out in the analysis process. We describe the development of CareVis – interactive visualization methods to integrate and combine classical data visualization with the visualization of treatment information in terms of logic and temporal aspects. We provide multiple simultaneous views to cover different aspects of a complex underlying data structure of treatment plans and patient data. The tightly coupled views use visualization methods well-known to domain experts and are designed to facilitate users’ tasks. The views are based on the concepts of clinical algorithm maps and LifeLines which have been extended in order to cope with the powerful and expressive plan representation language Asbru. The user-centered development approach applied for these interactive visualization methods has been guided by user input gathered via a user study, design reviews, and prototype evaluations. "
