Abstract

Hospital infections cost the lives of more than 100,000 people in the United States every year. Understanding how infections spread in hospitals is critical to reducing this problem. To help in this endeavor, we developed an interactive, multi-touch hospital contact-network visualization and disease spread simulation. The system visually animates healthcare workers as they move through a hospital building based on a very large, real world dataset of electronic medical record login sessions. Users control the visualization and infection spread simulation by direct manipulation using multi-touch interactions and on screen controls. Through our implementation, we explore how infection control experts might use visual analytics and multi-touch user interfaces to explore such large datasets. We share the feedback gathered from three domain experts, who tested our application and suggested additional use cases for similar systems or potential datasets.
