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.

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

Graph

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

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)
