Content updates

Our clinical team are continuously broadening, updating, and refining the Concentric ontology (i.e. the treatment templates), and updates are released every few weeks.

Most healthcare organisations use the main (‘master’) version of the Concentric ontology – those using this version will see updates as per the below release notes. Deployments using a locally modified version of the Concentric ontology sometimes receive updates on different dates to the main version, and the content of the updates can be different – including further local modifications requested.

Release notes for the last 6 content updates are presented in reverse chronology (most recent first). Earlier release notes are available on request. All the treatment templates available within Concentric can be explored on our treatment templates page, searching by treatment name or 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, listing new treatment templates made available and reviews undertaken, but do not detail every change within a release. Our reviews involve a review of the existing template alongside clinician feedback received, a review of the published evidence-base, and insights gathered from real-world use of the template – for example patterns in terms of risks modified or added.

If you don’t currently have access to Concentric but would like to see the Concentric ontology in context within the application please contact us to request demo access.
