  1. GCPR Near-Term Solution System Design Review John Leslie PRC Health Informatics Systems & Services Chief Architect GCPR Project

  2. Purpose/Scope • The purpose is to pass certain medical records on a select group of Department of Defense (DoD) patients through the GCPR Framework to the Veterans Affairs (VA) to be used by the VA's clinicians who will read the records using the VA's CPRS. This will achieve partial fulfillment of Presidential Review Directive 5 (PRD 5). • The scope is to provide a bridging network between Agency Systems. The information, which is to be exchanged, is defined in a number of “Partitions” which are defined by the Information Model.

  3. Real Scope NTS • Discharged/Retired only • Batch messaging HL7 v2.2 • Limited set of information

  4. Information View • RIM/RTM • Initial delivery as GFI December ‘00 • UML • Clinical Records in “Templates” • Describe structure of data exposed by Framework • Represented internally as Graphs • NTS Templates • Laboratory (Chem, Micro, AP, BB) • Radiology Reports • Outpatient Medications • Person Identity • Positively Identify Persons • Locate Clinical Record

  5. GCPR NTS Datatypes

  6. NTS Lab Template

  7. NTS Rad Template

  8. NTS Meds Template

  9. Graph • Generic structure based on meta-classes • ‘Normalized’ representation inside Framework • Based on RIM • Each Graph represents records

  15. NTS HL7 Add/Update Existing Patient Records ORU

  16. NTS Deliver Patient Records

  17. transformer • Adapters/Connectors • Connectors provide support protocol (ie ftp, IIOP) • Adapters components translate from one representation to another (ie HL7 to RIM) • Graphs/GraphCollections/GraphCollectionMgr • ‘Generic’ internal representation of RIM • Independent of underlying persistence • IGraphcollection (CacheGraphCollection, PersonGraphCollection)

  23. Current Status • Loading files • Beta testing • San Diego • Alaska • El Paso • Washington DC • Support/minor enhancements

  24. Future • More robust set of info • Adverse Reactions • Discharge Summaries • Etc...
