InformaticsandCRNs

• Datadefinition(CDEs,CDMs)• Datacapture(distributedacrossrolesandintegratedintoworkflows)

• Dataquality(fromdocumentmodeltodatamodel- notchartingbyexception)

• UDI(andGUDID,AUDI)

Informatics,CRNsandOpportunities

THE Foundational Issue

Electronic health information

The Foundational Solution

Registries, CRNs

Procedure reporting systems

Electronic Health Records

Clinical contexts

Native, Interoperable Data Standardization
