Clinical Observation Interoperability March 18, 2008 BRIDG Overview Clinical Observation Interoperability March 18, 2008
BRIDG Background Stakeholders: HL7, CDISC, NCI/caBIG, FDA Goals: shared semantics Domain of Interest: protocol driven research Project Organization: BAB, THC
BRIDG Content CDISC SDTM – Submission Data Tabulation Model HL7 CDA – Clinical Document Architecture NCI/HL7/CDISC caXChange/LabHub HL7 RPS – Regulated Product Submission CDISC TDM – Trial Design Model NCI PSC – Patient Study Calendar NCI CTOM – Cancer Trial Object Model NCI/? AE – Adverse Events NCI C3PR – Cancer Central Clinical Participant Registry
BRIDG Components UML (Unified Modeling Language) Static Model: Class diagram, Object diagram Dynamic Models: Activity diagrams, State diagrams, Sequence diagrams Abstract Data Types (HL7) Binding to Terminologies (NCI) Mapping to application models Mapping to HL7 RIM
Binding to Terminologies specifies the shared semantics at a comprehensive level at attribute level to both local and global terminologies occurs in context of run-time instances must remain implementation independent caBIG™ Cancer Data Standards Repository (caDSR) Enterprise Vocabulary Service (EVS) the BRIDG Model can be “implementation independent” in the sense that it should not specify structures like primary or foreign database keys, but it cannot remain implementation independent in the sense of ignoring run-time terminology bindings.
