Prepare, Blend, and Analyze FHIR Data in Alteryx Designer

Alteryx is a software platform that allows people to work with data more easily. When paired with CData Connect Cloud, Alteryx provides instant access to FHIR data from your data automation processes. This article demonstrates how to connect to FHIR using Connect Cloud and work with FHIR data in Alteryx.

CData Connect Cloud offers a dedicated SQL Server interface for FHIR, facilitating data querying without the need for data replication to a native database. With built-in optimized data processing capabilities, CData Connect Cloud efficiently directs all supported SQL operations, including filters and JOINs, straight to FHIR. This harnesses server-side processing to rapidly retrieve the desired FHIR data.

Configure FHIR Connectivity for Alteryx

Connectivity to FHIR from Alteryx is made possible through CData Connect Cloud. To work with FHIR data from Alteryx, we start by creating and configuring a FHIR connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "FHIR" from the Add Connection panel
3. Enter the necessary authentication properties to connect to FHIR.

   Set URL to the Service Base URL of the FHIR server. This is the address where the resources are defined in the FHIR server you would like to connect to. Set ConnectionType to a supported connection type. Set ContentType to the format of your documents. Set AuthScheme based on the authentication requirements for your FHIR server.

   Generic, Azure-based, AWS-based, and Google-based FHIR server implementations are supported.

   Sample Service Base URLs

   • Generic: http://my_fhir_server/r4b/
   • Azure: https://MY_AZURE_FHIR.azurehealthcareapis.com/
   • AWS: https://healthlake.REGION.amazonaws.com/datastore/DATASTORE_ID/r4/
   • Google: https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/

   Generic FHIR Instances

   The product supports connections to custom instances of FHIR. Authentication to custom FHIR servers is handled via OAuth (read more about OAuth in the Help documentation. Before you can connect to custom FHIR instances, you must set ConnectionType to Generic.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add FHIR Connection page and update the User-based permissions.

Connect to FHIR from Alteryx

Once you establish a connection to FHIR in Connect Cloud, you are ready to work with FHIR data in Alteryx. To begin, download the ODBC Driver for CData Connect.

1. In the ODBC Driver for CData Connect, select OAuth and click Test Connection. Then enter your CData Connect Cloud Credentials and Sign in.
2. Open Alteryx Designer and create a new workflow.
3. Drag and drop a new input data tool onto the workflow.
4. Click the drop down under Connect a File or Database and select the Data sources tab.
5. Navigate to the end of the page and click on ODBC under Generic connection.
6. Select the DSN that you configured for use in Alteryx.
7. In the wizard that opens, drag and drop the table to be queried in the Query Builder box. Select the fields by checking the boxes that you wish to include in your query. Where possible, the complex queries generated by the filters and aggregations will be pushed down to your data source, while any unsupported operations (which can include SQL functions and JOIN operations) will be managed client-side by the CData SQL engine embedded in the connector.

To further customize the dataset, you can open the SQL Editor and modify the query manually, adding clauses, aggregations, and other operations to ensure that you are retrieving exactly the data desired.

With the query defined, you are ready to work with your data in Alteryx Designer.
