Care Connect FHIR API standards
API standards using FHIR STU3 to create a unified approach to interoperability across England.
Important
The Care Connect FHIR API standards have been deprecated. They have been replaced by the Booking and Referral Standard (BaRS).
Overview
These API standards were developed by us along with the INTEROPen community to produce an England-wide FHIR STU3 set of profiles called CareConnect, which we published in November 2018.
The specification was published as a work in progress to support discussion and evaluation but not for implementation.
The FHIR standards work is continuing as FHIR UK Core using FHIR release 4 to create a unified approach to interoperability across England, Scotland, Wales and Northern Ireland. This is to enable consistent information flows across borders to improve health and care outcomes for all patients.
For queries and comments, email [email protected].
Status
These API standards are deprecated.
Reference server
We produced an open source reference implementation, based on the FHIR HAPI project, published as a set of Docker images. Using it, you can access:
- the open source code
- the design documentation
