Business Model

This implementation guide is to support Ontario miCDR using the FHIR standard with the following purposes:

  • FHIR based platform (R4 and higher)
  • Exposes a patient’s longitudinal record though a set of FHIR APIs (both provider and patient access)
  • Abstracts the underlying clinical repositories
  • Uses a hybrid model of local and distributed clinical repositories
  • Long term goal is to collect once, reuse many times

MiCDR FHIR API will support an asynchronous data flow for data contribution. When contributors submit data, the FHIR resources will not be created right away, instead the interface will return an HTTP code 202 that indicates it intends to process it. The request is placed in an internal queue for processing. Contributor does not have to wait for further response before sending another request. When the resources are later processed and stored in MiCDR, an asynchronous response will be sent to the contributor.

This diagram shows the data flow between entities in miCDR.

Actors

There are three main actors involved in MiCDR data flow:

  • Data Contributors: miCDR contributors are organizations that contribute their MI data to miCDR using the FHIR interface. Examples of miCDR contributors are regional diagnostic imaging repositories that consolidate data from diagnostic imaging systems across Ontario. Ontario Health has historically funded three (3) regional DIRs at the core of diagnostic imaging services in Ontario, namely:

    • Hospital Diagnostic Imaging Repository Services (HDIRS) for Central Ontario
    • Northeastern Ontario Diagnostic Imaging Network (NEODIN)
    • Southwestern Ontario Diagnostic Imaging Network (SWODIN)

  • Data Consumers: miCDR data consumers are systems that provide users access to miCDR data through miCDR FHIR interface. They may be viewers who display the data to their users, or HICs who uses their system to query and store MI data from MiCDR

  • MiCDR: The miCDR Repository is an Ontario Health digital health asset that supports sharing of patient data among health care providers. The repository provides APIs to be used by authorized systems to submit, retrieve, and display miCDR data to/from the repository.
