Active Work

  1. Write down Real World Integration Experiences (by Nov 23rd)
  2. Abstract Real World Integration experiences into generic interoperability workflows and user personas, we can build out technical workflows (by Dec 7th)
  3. Use them to figure out proposed architectures and use them to figure out a value proposition which includes user workflows
  4. Once we build out technical workflows, we can compare them against the existing OpenHIE workflows (roughly by the 15th of Dec)
  5. Then, we can identify FHIR specifications and begin make decisions on implementation details
  6. All CHIS can generate FHIR Patient resource
  7. All CHIS can generate FHIR Practitioner resource
  8. All CHIS can fetch ServiceRequest from HIE
  9. All CHIS can "claim" ServiceRequest from HIE
  10. All CHIS can initiate sending a task to CHWs based on the ServiceRequest
  11. All CHIS can send Encounter resource to HIE

TWG Workplan/Roadmap

Planned DateDescriptionNotes

Priority use cases and software identified

The Delphi Study was meant to help identify the priority use cases but there were some delays in the start of it. In the meantime, we have based the proof of concept on the Lost to Follow-Up use case. This only aligns well with some of the work being done in the Data Use Community and is also a use case that several consortium members have experience implementing in the field.

HL7 FHIR, HIE profiles and CQL for reference architecture reviewed

  • List of definitions of foundational resources
  • Gap analysis for CHIS related needs
  • Analysis of deployment options
The consortium has chosen to deploy the Proof of Concept using Instant OpenHIE. The prototype is being built with 4 key FHIR resources. 

Proposed reference architecture sketched out, software identified, and mapped to OpenHIE architecture

The Proof of Concept utilizes the Instant OpenHIE architecture.

Key CHIS capabilities and components mapped to WHO classifications

Pending Delphi study outputs.

 Shared concept library and associated concept map identified or developed

  • List of required concepts 
  • Selection of available libraries and tooling
  • Gap analysis 
  • Standardized HL7 FHIR artifacts
The initial proof of concept for the Lost to Follow-Up use case is being built around a minimal set of terminology/concepts. 

Proof-of concept built

Instant OpenHIE has been installed on shared infrastructure and a number of FHIR resources have been profiled and all three CHIS' are able to generate these resources and see them created in the HAPI FHIR server. The ServiceRequest workflow is still WIP. Information related to the proof of concept infrastructure can be found here
