IPDRA Mission
Help clinicians review patient data more effectively
before, during, and after patient encounters
Current Web application server
state-of-the-art Relational database
Source-oriented queries
Modest use of graphics
Limitations Time-consuming to query related patient
data from different parts of the database
.
Hard to mentally integrate data spanning
multiple pages and data sources

IPDRA Approach
Patient Present integrated, clinically-meaningful
data views subsets of each patient’s records
(by problem, body system, demographic).
Information- Compact, coordinated timelines and timedense displays series graphs with traditional text, tables.
Visual view Users specify view logic by drawing and
authoring configuring hierarchical flow charts.
Testing and Desktop application lets users test and
debugging debug view definitions and upload them to
the server.

Key Questions
Effectiveness How should we design patient views to
enable effective and efficient data review
by clinicians?
Feasibility What software tools and processes can
enable practical design and
development of large libraries of views?

IPDRA Status
• Prototyped IPDRA view server and
test/debug application
• Developed initial set of views using ICDB
• Evaluation and refinement of views planned
for fall 2004 using DoD M2 clinical database
• IPDRA subsystems released as products
• Java SimBionic visual authoring tool (Feb 2004)
