Convert - CDA to FHIR (R4)

POST /convert/v1/cdatofhirr4/:patientID

This operation converts a CDA document into a FHIR R4 bundle.

Inputs and Outputs

The input for this operation is a single CDA document. Supported CDA formats/versions are:

• C-CDA R1.1/R2.1
• HITSP C32 CDAs

The output is a FHIR R4 Bundle containing the clinical data parsed out of the CDA, along with an OperationOutcome resource detailing the results (including warnings or errors) of the conversion process.

Data Format

The input for the CDA to FHIR conversion is XML, so be sure to specify content-type: application/xml in your request header.

You can specify either accept: application/json or accept: application/xml in your request header to get a response in either JSON or XML format.

Example

CDA documents and FHIR Bundles are verbose, so this just shows a small sample to illustrate how the data is structured. For a more complete example, try out the API in the Developer Portal Sandbox.

For example, a patient node in the CDA XML:

  <patient classCode="PSN" determinerCode="INSTANCE">
      <name>
          <given>John</given>
          <family>Smith</family>
      </name>
      ... 
  </patient>

would be converted to a Patient resource in the FHIR bundle:

  "resource": {
    "resourceType": "Patient",
    "id": "35b77437-425d-419c-90b5-af4bc433ebe9",
    "name": [
        {
            "use": "official",
            "family": "Smith",
            "given": [
                "John"
            ]
        }
    ],
    ...
  }
