Create FHIR-Connected Dashboards in Grafana



Connect to FHIR Data via CData Connect Cloud in Grafana and create custom business dashboards with real-time access to FHIR data.

Grafana is an open-source platform that allows users to analyze, monitor, and visualize telemetry from various data sources. When combined with CData Connect Cloud, you gain immediate access to FHIR data for business dashboards. This article outlines the process of connecting to FHIR using Connect Cloud and creating a basic dashboard from FHIR data within Grafana.

CData Connect Cloud offers a pure SQL Server, cloud-to-cloud interface for FHIR, enabling the creation of dashboards directly from live FHIR data within Grafana, all without the need for data replication to a native database. As you build visualizations, Grafana generates SQL queries to gather data. With its inherent optimized data processing capabilities, CData Connect Cloud efficiently channels all supported SQL operations, including filters and JOINs, directly to FHIR. This leverages server-side processing to swiftly deliver the requested FHIR data.

Configure FHIR Connectivity for Grafana

Connectivity to FHIR from Grafana is made possible through CData Connect Cloud. To work with FHIR data from Grafana, 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.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

  1. Click on your username at the top right of the Connect Cloud app and click User Profile.
  2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
  3. Give your PAT a name and click Create.
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to FHIR data from Grafana.

Visualize Live FHIR Data in Grafana

To establish a connection from Grafana to the CData Connect Cloud Virtual SQL Server API, follow these steps.

  1. If you have not already done so, download and install Grafana for your operating system from the Grafana Website. Once installed, access Grafana at http://localhost:3000/.
  2. Log in to Grafana with your username and password for Grafana. If this is your first time logging in, the username is admin and the password is admin.
  3. On the navigation menu, click Connections > Add new connection. On this page, you can search for Microsoft SQL Server and select it as your data source.
  4. Select Microsoft SQL Server and click Add new data source.
  5. Enter a name for the new data source and then enter the following connection settings:
    • Host: tds.cdata.com:14333
    • Database: enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, FHIR1).
    • Username: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected].
    • Password: enter the PAT you previously generated.
  6. Click Save & Test. A Database Connect OK message appears when you have a successful connection established.

Create a Dashboard

Once you create the data source for FHIR, you can start building dashboards on FHIR data. Start in the navigation menu and click Dashboards

  1. On the Dashboards page, click + Create dashboard, then click + Add visualization.
  2. This opens the Select data source window where you can select your created connection.
  3. After selecting your connection, you can choose the tables and columns that you want to query for your visualization. Then press Run Query to run the generated query.
  4. After running your query, the resulting data is populated above the query editor. Here you can select the visualization that you want to use to present your data on the dashboard panel.
  5. When you have finished editing your panel, you can click Save dashboard to save the changes made to your Dashboard.
