Mental Health & Addictions 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.pdfTo 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 for the Release 1 solution, 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,
- three other subject area ERDs, one for each of the three Release 1 Mental Health & Addiction profile subject areas, and metadata is included for each attribute

---|---|---|
Health Care Encounter (Appointment) | An event occurring at a given time and place, where one or more services or products are provided to assess, maintain or improve the health of the health care client.
Types of encounter include: inpatient, outpatient, emergency, ambulatory, telehealth, community care, long-term care etc. Could be unplanned (e.g. ER visit) or planned (e.g. doctor’s appointment). A self-care encounter is self-provided, e.g. glucometer reading, treatment of a wound, non-prescription medication. An encounter may be a step in a larger care process. The status of the care process may be noted by the provider as part of the encounter. Also includes phone calls and email correspondences between health care clients and health care providers. Encounter information should be categorized to support functionality to consolidate diverse, high-volume encounter information gathered over an extended period. May have an encounter-level outcome (as distinct from an Episode of Care Outcome) with information details such as:
Encounters can also be for individual health care clients or for groups of health care clients. If it is a group encounter then the EHR should document the fact that it is a group and group characteristics such as name of group, size of group, health care professionals conducting the group should be included. In this context (i.e. appointment), Encounter represents a booking of a healthcare event among patient(s), practitioner(s), related person(s) and/or device(s) for a specific date/time. This may result in one or more Encounter(s). It is realized in this specification as an Appointment. |
Appointment |
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. For Mental Health & Additions, Health Condition represents a condition the patient suffered in the past. |
Condition |
Health Care Provider | Describes a health care provider involved in the delivery of healthcare services. Encompasses both professional and non-professional members. Has professions, areas of practice for which the provider is qualified. May have information on clinician credentialing and privileging as defined by the applicable professional and governing organizations. This includes remote participation (e.g., via tele-health activities such as tele-consultation, home health monitoring.) Includes any information about licensing status and license suspension. May be an author, authenticator or scribe/transcriber of clinical documentation. Has a Unique Provider Identifier, a key assigned by eHealth to uniquely identify each Provider. May have a health system universal ID. May have a license number or national provider identifier (U.S.). May have multiple unique identifiers. | N/A |

If it is a group encounter then the EHR should document the fact that it is a group and group characteristics such as name of group, size of group, health care professionals conducting the group should be included. In this context, the Encounter represents the Health Care Encounter information as captured during the encounter between the Health Care Provider and Health Care Client (e.g. fulfilling the appointment). |
Encounter |
Provider Episode of Care | A series of Health Care Encounters to address one Health Condition by the same Provider Person.
An episode of care starts with the first contact with the provider for the health issue and it ends after the last encounter with the provider for the Health Condition. A hospital stay is represented by a Provider Episode of Care for the Most Responsible Physician. An episode of care for a home care referral may include different provider persons. An association between a patient and an organization / healthcare provider(s) during which time encounters may occur. The managing organization assumes a level of responsibility for the patient during this time. |
Episode of Care |
Client Supporter | Legal entity (i.e. either an individual or an organization) holding rights and responsibilities for a health care client with respect to health care. A health care client managing his or her own care acts as the health client. Where care of a health care client is legally managed by another person, that person is the health client. Includes power of attorney and substitute decision maker. Includes personal representative, advocate, healthcare proxy, legal representative, financially responsible entity. It includes information about contact method e.g. geographic or virtual address, telephone number. | Patient.Contact(Contact element within Patient Resource) |

Examples:
May include expected turnaround time for service delivery, e.g., the time from when a lab receives a specimen to when test results are available. |
Healthcare Service |
Health Care Provider Product Location | An address or other identifiable locale at which health products have been provided to an individual health care client in a Health Care Encounter, often by a particular provider playing a particular role.
It may also be:
Locations and contact information may refer to the location of the provider within a health care facility's premises e.g. a hospital unit. Products and services can be provided by non-licensed providers e.g. caregivers. In this context, the Health Care Provider Product Location provides details and position information for a physical place where services are provided and resources and participants may be stored, found, contained, or accommodated. | Location |
Observation |
Information derived from performance of a health related activity.
An observation may be clinical i.e. made during an Encounter, or it may be made during a laboratory test. These are distinct types of observations. Observations often involve measurement or other elaborate methods of investigation, but may also be simply assertive statements, findings, symptoms, conclusions, etc. e.g. triage disposition or acuity or severity of a condition. An Observation may be a self-observation made by a health care client, e.g. blood pressure, photograph, pulse. These may be annotated by an authorized health care provider. May be broken down into several types:
An alternate classification based on the nature of an observation:
May include annotations. May be preliminary or final. May be from any care setting e.g. hospital, lab, EMS. May be measurement from an ancillary system or external device. Information may be from telemetry i.e. a real-time or near-real-time feed. May be provided by non-medical devices (e.g., digital camera or sound recorder). May be a recorded audio narrative e.g. from EMS. May include the following attributes, if applicable:
