GCPR Near-Term Solution System Design Review

GCPR Near-Term Solution System Design Review

John Leslie

PRC Health Informatics Systems & Services

Chief Architect GCPR Project

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

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
