Content release notes

Our clinical team are continuously broadening, updating, and refining the Concentric ontology (i.e. the treatment templates), and release updates every week or so.

Most of our deployments use the main version of the Concentric ontology, and therefore updates will reflect the updates below, but in some cases organsiations have a slightly altered version of the ontology, with updates not necessarily done at the same time as the main version.

These release notes are listed with the most recent first, and start from January 2023 when we began releasing content release information publicly. The list of all the treatment templates available within Concentric, presented by specialty, is maintained in our Concentric treatment template list. You can also click any of the specialty titles below to go to the relevant sheet for that specialty.

Each release goes through a thorough release process, as outlined within our release process page. These release notes highlight the recent areas of focus, and lists new treatment templates made available, but do not detail each change that is made within the ontology for each release.

If you don’t currently have access to Concentric but would like to see the Concentric ontology in context within the application please email us at
