Retrieve Document

This transaction can be used to retrieve documents from a SHR or document repository that stores health records. In addition, a vaccine verifier (point-of-care application or any authorized application outside of the HIE) can use this transaction to verify a Digital Documentation COVID Certificate (DDCC) Immunization event. This may include COVID immunizations and negative tests.

Workflow Maturity

Newly Defined

  • Workflow is defined by WHO and has OpenHIE ARB approval
  • Initial implementations are being considered.
Standards

Assumptions and Prerequisites

  • The appropriate trust agreements and processes have been put in place for the document requester or Verifier to receive the certificate.
  • The appropriate documents or meta data about the document have been stored. This may include saving a vaccine or a lab test event to a shared health record via Register / Store Document or Save Patient-level Clinical Data Workflow.
Actors

  • Document Requester or Verifier (External System) - External system or Point-of-care system requesting the document or vaccine status.
  • IOL - The interoperability layer that secures and orchestrates the exchange of information
  • SHR / Document Repository (or Electronic Vaccination Registry) - The shared health record that serves as a centralized data store for patients’ longitudinal health record and or health documents

Interaction Description

The Interaction Description is stored in the "Retrieve Health Certificate Reference" in the WHO FHIR IG.
