Patient Summary 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 FHIR interoperability standard for patient summary specifications. 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 - The current official version of FHIR as of the time this implementation guide was published.
  • International Patient Summary FHIR Implementation Guide - This specification is a key input into the design of the Ontario Patient Summary Implementation Guide.
  • Patient Summary - Canadian Edition Release 1 (PS-CA) - The Ontario Patient Summary is intended to be closely aligned to this Pan-Canadian Patient Summary initiative.

Conceptual Data Model ERDs and Metadata

Entity Relationship Diagrams (ERDs) follow. These include:

  1. a conceptual high-level ERD for solution data structures for the Release 1 solution, including metadata for each entity,
  2. 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,
  3. six subject area ERDs, one for each of the six Release 1 Patient Summary profile subject areas; each Subject Area corresponds to a Profile defined for the FHIR International Patient Summary (see http://hl7.org/fhir/uv/ips/ipsStructure.html ), and metadata is included for each attribute, and
  4. one non-clinical subject area ERD with metadata for each attribute, for Patient Summary document composition.

In the Patient Summary context, it is clinical problems or conditions that are currently being monitored for the patient. Used to provide a concise overview of active health conditions affecting the patient.
Procedure
Health Condition A mode or state of being, the state of being fit: the physical status of the body as a whole or of one of its parts usually used to indicate abnormality.
May include a descriptive narrative. Over time a health condition can change in nature or acuity, or split or merge. It includes all diseases and disorders, specifically to denote any illness, injury, disease, or complications from existing health conditions or treatment. A health condition may be contagious, having implications on health care client management. A health condition may be genetically based.
A health condition can also be positive, e.g. pregnancy, wellness. It can be physical, mental or emotional.
In the Patient Summary context, it is the historical information and events that the patient has previously encountered. To provide a comprehensive overview of a patient’s healthcare interactions that could improve clinical diagnosis, treatment, and condition management. Used to provide a comprehensive overview of a patient’s healthcare interactions that could improve clinical diagnosis, treatment, and condition management.

  • Resident (of a long term care facility)
  • Subject (in a public health case)
  • Client (in home care/community care cases/ settings)

Sensitivity A susceptibility to an agent or substance or category of substances, such that exposure to it is likely to result in a harmful physiological response rather than the expected (non-harmful, normal) physiological response AND where it has not been possible to determine whether the sensitivity is of the allergic type or not. (CHI)

AllergyIntolerance
Substance Intake - Immunization The administration of a substance into the body key to the management of a health care client's condition(s).
May be self-administered or administered by a Health Care Provider. May be administered by a device.
Intake can be medication or nutrition, e.g. daily consumption of food items, beverages, or oral medication, injected medication such as a pain killer or the topical application of a patch. It can be a meal type (e.g. breakfast), and can have a specific time or date associated with it. It can be PRN i.e. taken as needed, including adjustment of dosage to suit needs.
An example of an intake is an immunization: an application of a technique (e.g. vaccination), that induces immune resistance to a specific disease by exposing the individual to an antigen in order to raise the level of antibodies to that antigen. May record:
