Information Visualization Compact graphical presentation and user interface for manipulating large numbers of items (102 - 106), Enables users to make discoveries, decisions, or explanations about patterns or groups of items Visual bandwidth is enormousHuman perceptual skills are remarkable
Spotfire: e.g. Retinol’s role in embryos & vision Revealed the previously unknown involvement of the retinol binding protein RBP1 in cell cycle control.(Stubbs S, & Thomas N. 2006 Methods in Enzymology; 414:1-21.)

e.g. NCHS data Size = #Deaths per 100 000, in 1998 Color = Rate of change compared to 1981

Lifelines2 • Introduce powerful combination of simple operatorsAlign, Rank, Filter, and Summarize • Multiple records simultaneously visible • Align by key events • Rank by frequency • Filter by events sequences • Provide summaries Integrated in i2b2 and BTRIS Open source The work of Dave Wang [Wang et al. 2008, 2009] - www.cs.umd.edu/hcil/lifelines2

Twinlist Facilitating Medication Reconciliationwith Animation and Spatial Layout
Medication reconciliation • Develop list of current medications • Develop list of medications to be prescribed • Compare lists • Make clinical decision based on comparison • Communicate the new list to appropriate caregivers and to patient One definition from: http://www.ihs.gov/cio/ehr/index.cfm?module=medication_reconciliation
Medication reconciliationScenario: Hospital discharge • Intake Hospital • What’s unique? • What’s identical? • What’s equivalent?
Levels of equivalences “Automated medication reconciliation and complexity of care transitions”Bozzo Silva, Bernstam, Markowitz, Johnson, Zhang and Herskovic, AMIA 2011
