Effective medical care depends on well-designed user interfaces that enable clinicians and medical researchers to apply novel strategies in information visualization to explore Electronic Health Records (EHRs).  in systematic yet flexible ways, so as to derive insights and make discoveries.

This talk reviews more than a decade of research on visualizing and exploring We begin with LifeLines (www.cs.umd.edu/hcil/lifelines) for viewing a single patient history and then show LifeLines2  (www.cs.umd.edu/hcil/lifelines2) to view compact summaries of thousands of patient histories represented as time-stamped events, such as strokes, vaccinations, or admission to an emergency room.  Our current work on EventFlow (www.cs.umd.edu/hcil/eventflow) also supports interval events such as medication episodes or long hospitalizations. Demonstrations cover visual interfaces to support clinicians in making treatment decisions and hospital quality control researchers who study treatment patterns that lead to successful outcomes. Finally, we show how EventFlow can be applied to other domains such as web log analysis and sports team performance.
