Electronic Patient Records
Where can we be? – A Technical Perspective

CERC, West Virginia University
The Holy Grail
Secure, Survivable, Scalable, Distributed, Heterogeneous, Legacy-aware
Available – on demand and just-in-time, adapt to the device at hand
Integrate with workflow
Economically justifiable and legally compliant
The Health Care World
The Web Sparks the Imagination
ABC News Report -1996
The Problems - Then
Stateless Web
Creating Dynamic Webpages
We have come a long way since 1996
But only technically speaking….
Partial implementations only in the top 100 medical facilities (recent wall Street Journal report)
Pharmacies have embraced the technology
Economic Incentive
XML
The new favorite technology that is a solution for any problem!!
Why XML?
We can make the  Web information “understandable” to programs (or “agents”)
“Semantic Web” is now feasible
Just one small detail – we need to develop the complete ontology
There is now a plethora of XML derivatives (xXML)
Voice XML
Can render pre-recorded speech  or convert text to speech
Voice Gateways (e.g. bevocal)
When hands and eyes are occupied
V-Architecture
VoiceXML Architecture
Wireless XML
Can render patient records on hand-held devices
Now ubiquitous wireless phone can become the interface device
WfXML
Integration of workflow with patient records
An “instant message” can be set to trigger a series of predefined activities (e.g. scheduling appointments)
DOM
Document Object Model
Patient Record as a special document
New Capabilities (e.g. event triggering – lab result filling will trigger notification)
Ad Hoc Networking
Wireless “hot spots” provides ubiquitous access to web based information
Enterprise/Campus wide access
Unification of Distributed Sources
JSP/ASP to create unified pages from diverse sources
RMI/CORBA/JINI support distributed computing model
Example – virtual unification of pharmacies with hospital data
Mobile Services
Mobile Computing
Location based services
Provider can receive customized information depending on location
Supporting mobility of patient and provider (e.g. mobile patient sending periodic readings…)
Searchable  Distributed Patient Record
All sources are accessed transparently and isomorphously
Access to paper based records are mediated by a person – on demand
Embedded language mapping ( with intervention!)
San and Nas
Storage Area Nets & Network Attached Storage Technologies
Contributing to Survivability
Conclusion
The revolution technology promises hasn’t come yet.
Economic incentive is the most potent driver
Learn from legislation driven advancements such as CAFÉ in Auto Industry
Make the Impossible Possible!!!
