DHDR Conceptual Data Model

This model is linked to Ontario’s Electronic Health Record (EHR) Conceptual Information Model 2.0 (CIM 2.0). See: https://ehealthontario.on.ca/files/public/support/Architecture/Ontario_EHR_CIM_2.0.pdf

To support the use of structured data through the adoption of data content and health terminology standards in the solution, this CDM also includes high-level entity relationships and attributes discovered in versions of the FHIR R4.0.1 interoperability standard. The model does not repeat the structure of the messages laid out in FHIR. Links to FHIR specs are included for entity definitions and field code values. In any difference of meaning between cited FHIR elements and this model, FHIR is the authoritative voice. This model relies on the following specifications:

  • FHIR R4.0.1 - The current official version of FHIR as of the time this implementation guide was published

Conceptual Data Model ERDs and Metadata

Entity Relationship Diagrams (ERDs) follow. These include:

  • a conceptual high-level ERD for solution data structures, including metadata for each entity
  • an ERD for the Client & Provider subject area (including metadata for each entity) which is not called out as a FHIR Profile but is included because all other entities in the model are dependent on it,
  • two subject area ERDs, each Subject Area corresponds to a Profile and metadata is included for each attribute

DHDR Conceptual Data Model

The Conceptual Data Model that follows describes the concepts that are available via DHDR, but are general descriptions of the concept within the context of the broader health care system and an Electronic Health Record (EHR). The definitions of the entities are taken specifically from the EHR Conceptual Information Model and are meant to cover the broad spectrum of the data across the EHR. The information that is available via the DHDR interface may only contain a subset of the concepts described in the definition of the Entity. For information related to the specific concepts and data subsets available via the DHDR API, please see Information Available to Health Care Providers through the Digital Health Drug Repository, EHR Health Care Provider Guide and www.ontario.ca/mydruginfo.


Entity Name Description FHIR Resource Name
Healthcare Client An individual participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. (U.S. National Library of Medicine - Medical Subject Headings)
A natural person (i.e. a human being) who:
  • is eligible to receive health care services in Ontario, or
  • has received or is receiving health care services in the province of Ontario (i.e. a health care client).

This entity covers personal identifying information but not health information. It includes information about:
  • identity within the health system e.g. a Health Number; each care setting may have a separate unique ID. E.g. a research study may uniquely identify a health care client as a test subject.
  • administrative gender, e.g. Male, Female, undisclosed
  • adoption: whether or not the health care client was adopted
  • birth and death dates
  • official versus preferred name
  • whether or not the health care client would prefer to receive correspondence

The health care client's identity may be unknown e.g. for a protected person or if the identity of the health care client is unknown. A health care client may be a VIP whose identity must be omitted from reporting. A health care client may be identified by an alias. Health care client-identifying information could include a photograph. May be elated genetically or by physical co-location (e.g. residential, occupational, travel, etc.) to another person not necessarily a health care client. Depending on care setting, a health care client may be referred to as:
  • Patient (currently receiving care)
  • Participant (in a clinical study)
  • Resident (of a long term care facility)
  • Subject (in a public health case)
  • Client (in home care/community care cases/ settings)
