IT and Health Care

Health care is an information- and knowledge-intensive enterprise. In the future, care providers will need to rely increasingly on information technology (IT) to acquire, manage, analyze, and disseminate health care information and knowledge.

TRUST Strategy

Community view: What matters is clinical performance and not the insertion of IT per se.

– Building experimental systems is essential. – Strategic partnership and extensive collaboration with major medical informatics research partners is required (Vanderbilt Medical School, EU Medical Informatics Programs).– Focus on specific research projects addressing key challenges

o Privacy Modeling and Analysiso Architectures for Trustworthy Health Information Systems o In-home patient monitoring

– Collaboration among TRUST partners and with external organizations to complement our resources.– Integrating research results into an experimental platform that is field tested and presented to industry for transitioning.

Architectures for Trustworthy Health Information Systems (THIS)

Vanderbilt (Ledeczi, Lee, Sztipanovits) investigates a formalized design approach to model-based development of Health Information Systems.

• Formal system modeling

• Formal policy modeling

• Model verification for security and privacy properties of the modeled architecture

• Model-based generation of run-time components

• Model-based system integration
