HL7 to FHIR Server Sample Profile Workflow

The profile has the following routes:

This route receives an HL7 data file as an input, splits the file, and performs the corresponding operation on a FHIR server depending on the type of each split HL7 transaction (the route analyzes the HL7 Trigger Events: ADT 01 = CREATE, ADT 03 = UPDATE, ADT 08 = DELETE).

Route Components Description

Component Name Component Type Description
FS Inbound_HL7 FS Inbound Picks up an HL7 data file form the file system.
Validate and Split XE Native Validates and splits the incoming HL7 file into individual transactions. For each split transaction, extracts the HL7 Trigger Event value and sends this value further down the route as a property (messageType).
HL7 to FHIR Bundle Transl Translates each transaction to the FHIR Bundle format.
Router Router Splits the message flow for creation, update, or deletion based on the messageType property.
POST Bundle FHIR System Action POSTs a FHIR Bundle onto the FHIR server.
Groovy Groovy Prepares a FHIR Bundle for the POST operation. Sets the method to "PUT", creates ifNoneExist elements, and so on.
Delete by Patient Subroute Calls the route Delete by Patient to remove patient data from the FHIR server.
Status Router Checks the FHIR server operation status, and if the response from the FHIR server is other than 200 OK, directs the message further as failed.

This route deletes FHIR resources related to the same patient from the FHIR server. The route has several chained components FHIR System Action each responsible for removing particular FHIR resource type.

Route Components Description

Component Name Component Type Description
Parent Route Input Parent Route Input Receives FHIR Bundle from the route HL7 To FHIR.
JSON Value Extractor JSON Value Extractor Extracts patient identifier. The subsequent route components use this identifier to remove FHIR resources related to this patient.
Delete {ResourceName} FHIR System Action Each component removes the corresponding patient's resource from the FHIR server.
Parent Route Output Parent Route Output After the required resources have been removed, returns the resulting FHIR bundle back to the route HL7 To FHIR.
