Data Consumption Use Cases – Provider (User) Queries
The use cases below provide a basic illustration of how actors interact with MiCDR using the Provider Query.
UC-Q1 – Provider requests a list of Patient's MI Information (reports, and/or orders, and/or imaging studies) – Information successfully returned
Provider requests a list of MI information via provider application with a specific date range and patient identifier. The record(s) for the patient's identifier is found in MiCDR. Information (MI report(s), and/or order(s), and/or imaging study(s) information) is successfully returned by MiCDR via the Provider Gateway.
Steps:
- Provider enters search criteria in Provider Application.
- Provider Application formulates the search request and submits a DocumentReference search request to the Provider Gateway
- Provider Gateway authorizes and validates the requests and forwards a request to MiCDR.
- MiCDR uses patient identifiers provided and makes two calls to PCR and CMTA.
- PCR validates patient identity using health card number and DOB.
- CMTA validates that no consent block is in place.
- All identifiers associated with the patient (e.g., multiple MRNs) are retrieved from PCR.
- Searches MiCDR using patient identifiers.
- Information is found in MiCDR.
- MiCDR returns information (DocumentReference resources) from MiCDR for the specified patient to a provider application via the Provider Gateway.
- Provider Gateway forwards response to Provider Application.
- Provider Application displays the relevant information received from the Provider Gateway to a provider.
Alternate Workflow:
- No records found
- MiCDR returns a message indicating that no records were found for the provided search parameters.
UC-Q2 – Provider requests details of a specific MiCDR record
After successful return of MiCDR records, a provider requests details of a specific MiCDR record (e.g., selects one record from the list of records); follows completion of UC-Q3.
Steps:
- Provider performs an action in Provider Application to view details of a specific MiCDR record.
- Provider Application formulates the request (this triggers an HTTP GET to the URI of the MI record in the list) and submits it to the Provider Gateway.
- Provider Gateway authorizes and validates the request and forwards to MiCDR.
- MiCDR returns information from MiCDR to a provider application via the Provider Gateway.
- Provider Gateway forwards response to Provider Application.
