A Virtual Medical Record (vMR) is a data model, based on the HL7 RIM format, for representing clinical information inputs and outputs to/from clinical decision support services. Data is exchanged with local clinical information systems at the point of care, through a software middleware layer that translates the data into a standardized vMR format. vMR Project Scope HL7 Atlanta – 9/07 Virtual Medical Record (vMR) for Clinical Decision Support (CDS) 3

The goal of this project is to create an HL7 vMR data model recommendation and implementation guide, based on the HL7 V. 3 RIM, which is capable of supporting clinical decision support (CDS) for chronic disease management at the point of care. vMR Project Goal HL7 Atlanta – 9/07 Virtual Medical Record (vMR) for Clinical Decision Support (CDS) 5
vMR Project Deliverables & Timeline HL7 Atlanta – 9/07 Virtual Medical Record (vMR) for Clinical Decision Support (CDS) 6 DeliverablesTimeline Clinical Decision Support (CDS) Storyboards for: 1.Breast Cancer screening and treatment, including family history and genomics. 2.Type 2 Diabetes. 3.Asymptomatic Unruptured Cerebral Aneurysms, Risk Assessment & Management. 4.Hypertension. Others TBD Summer-Winter 2007 For each of the above storyboards, develop a set of HL7 Project technical materials, including: - Activity Diagrams. - Use Case Models. - Specification models. - Gap analysis between existing HL7 standards specifications and requirements for CDS use cases.
vMR Project Timeline HL7 Atlanta – 9/07 Virtual Medical Record (vMR) for Clinical Decision Support (CDS) 7 DeliverablesTimeline Recommendations to other HL7 Technical Committees for revisions to existing HL7 data models and identification of new elements required for computer-enabled clinical decision support. Spring – Summer 2008 CDS recommendation on an HL7 vMR (V.3) meta-model for clinical decision support representation and information exchange. Testing of this recommendation within two European Union projects – and Cocoon Projects. Both projects requiring the vMR recommendation to be comprehensive enough to support computer- enabled clinical decision support. HL7 vMR (V.3) Implementation Guide to enable implementers to develop the infrastructure necessary for using computer-enabled clinical decision support.
vMR Project Outreach HL7 Atlanta – 9/07 Virtual Medical Record (vMR) for Clinical Decision Support (CDS) 8 Extensive outreach done prior to finalizing project scope. HL7 Board Members, Technical Steering Committee, Infrastructure & Modeling, RCRIM, UK Affiliate, Patient Care. AHRQ, CDISC, DoD, NCI, VA. Will continue to provide periodic updates to interested parties who cannot attend HL7.
vMR Project Alignments Identified to Date HL7 Atlanta – 9/07 Virtual Medical Record (vMR) for Clinical Decision Support (CDS) 9 HL7 TCs & SIGsProjects Clinical Decision Support TC TC Sponsor Clinical Genomics SIG Template SIG EHR TC Patient Care TC Clinical Interoperability Clinical Documents European Union & Cocoon projects to deliver computer-enabled CDS to PoC. Harvard/Partners – Clinical Genomics Patient Profile for EHR. US HITSP ONC – Personalized Healthcare. HL7 RCRIM/CDISC – Aspire Project to deliver clinical trial patient eligibility criteria.
HL7 vMR Project Approvals HL7 Atlanta – 9/07 Virtual Medical Record (vMR) for Clinical Decision Support (CDS) 10 HL7 Project Management Office (PMO). HL7 Architectural Review Board (ARB).
vMR Business Use Cases HL7 Atlanta – 9/07 Virtual Medical Record (vMR) for Clinical Decision Support (CDS) 11 The project team will define 4 initial business use cases, including storyboard, activity diagram, and specification model: 1.Breast Cancer with Genetic Extension (in progress) 2.Diabetes Type 2 (in progress) 3.Asymptomatic Brain Aneurism 4.Hypertension Other business use cases will be developed with approval of CDS work group and if resources are available to develop required HL7 project materials.

vMR BUC Issues How to represent CDS Service Determination pros and cons; both encoded and narrative text. Re-interpretation of patient genetic profile as data elements are updated in EHR, including how re-interpretation will be initiated: auto-generated via EHR or CDS Service, or person- initiated via EHR; and how patient consent will be obtained. Need for knowledge databases of: DNA variations (or variant combinations). Coded clinical significance: Unknown Significance to Pathogenic or Benign. The system receiving notification of the change might then propagate this information, flagging records for re- evaluation.

vMR Project - Next Steps Set up more formal lines of communication to aligned HL7 TCs and SIGs. Evaluate alignment to other projects. i.e. US HIT ONC Personalized Health & HL7 RCRIM/CDISC ASPIRE Project. Evaluate alignment to CEN vMR. Continue business use case development.
