UC-02 Query and Retrieve Document

1) A Health Care Provider, in any care setting, queries and retrieves a clinical document for use at the point of care

A patient schedules a visit with a health care provider, outside of their Medical Home, with symptoms including dizziness and an earache. The patient mentions that they have a regular health care provider, within their Medical Home, and experiences high blood pressure (hypertension) which is being monitored at home for now. The health care provider collects information from the patient and, using their Clinical Solution (e.g., EMR),  searches for clinical information (e.g., searches the network to locate clinical documentation created and shared by another Health Care Provider). Upon finding a clinical document(s) for their patient, the health care provider views and uses the information in support of providing care for this patient.

2) A Patient or Subject of Care accesses/views and can obtain a copy of their own personal health information.

A patient, or their designated caregiver, would like to access their personal health information (PHI) to stay up to date with their medical health information, empowering them to play an active role in their own care.

This section describes example triggers, pre-conditions & post-conditions related to the query and retrieval of clinical document(s) from the Clinical Data Repository. It is not inclusive of all potential workflow scenarios which may be implemented within Canadian jurisdictions.

Triggers

Scenario 1:

• • • Patient visits Health Care Provider for care.
    • Where applicable, HCP received a notification that new clinical information is available for the Patient to which they have subscribed to receive notifications.

Scenario 2:

• • • Patient, or their designated caregiver, chooses to view personal health information to stay informed of their medical information. 
    • Patient wants to obtain a copy of their personal health information to have on their person while travelling.
    • Patient wants to obtain a copy of their personal health information to share with another care provider.

Pre-conditions

Scenario 1:

• • • Health Care Provider is logged in to their Clinical Solution (e.g., EMR).
    • Health Care Provider's Clinical Solution is connected / part of the Clinical Data Repository network.

Scenario 2:

• • • In jurisdictions where a patient may have applied consent directives to their clinical information, HCP complies with local/jurisdictional privacy policies.
    • A jurisdictional clinical system with patient access is available. 
    • If applicable, patient has designated and authorized a designated caregiver to access their personal health record on their behalf.

Post-conditions

Scenario 1:

• • • Health Care Provider views and uses the clinical document(s) in support of Patient care.

Scenario 2:

• • • Patient, or their designated caregiver,  accessed/viewed, and optionally printed a copy of, their personal health information.
    • Patient, or their designated caregiver, presents their personal health information to another health care provider to support continuity of care.

Use Case - Primary Flow

The following provides a textual description corresponding to the use case diagram.

1. Participant (i.e., Health Care Provider or Patient / Subject of Care) determines need to view clinical information.
2. Participant requests access (i.e., queries) for clinical information via the clinical solution.
3. Clinical Data Repository applies applicable business/policy rules (e.g. validates requestors credentials).
4. Clinical Data Repository prepares and returns the FHIR bundle with corresponding clinical document(s).
5. Participant views/uses the clinical document(s) in support of care for the Patient or themselves.

Use Case - Alternate Flow

The following list provides possible alternate flows that may occur within this use case.

• Step 3: Patient Consent Services are not currently supported in the CA:FeX specifications. However, Patient consent is considered as a roadmap item and would be represented in a separate use case at that time where a Patient has identified consent directives requiring the Health Care Provider to address prior to accessing the Patient's clinical information. It is recognized that some jurisdictions may have existing Patient Consent Services implemented and should be considered when implementing with that jurisdiction.
