The development of the N3 based interface approach is influenced by RESTful service interfaces and the emerging HL7 FHIR (Fast Healthcare Interoperability Resources) standard. The e-RS roadmap shows the timetable of planned system enhancements.
API integration phase 1
This has provided the foundation to support initial clinical system integration. The initial Clinical Referral Information (CRI) APIs are being evaluated with pilot suppliers and will support the transfer of clinical documents within hospital clinical systems. The CRI API can also potentially be used by providers who have Referral Assessment Services (RAS) on e-RS to support the patient registration process. Find out more about the guidance on using APIs with RAS.
API integration phase 2
This is now represented at a more detailed level within the new Integration Roadmap for the 2017/18 financial year. This will enhance the API tools to support referral system integration and provide improved clinical triage functionality to allow clinical system providers to integrate with the Service.
The ecosystem to support partner's API consumption is being finalised. This will provide user information and documentation on the engagement process, API architecture, test environments, FHIR resources and other development resources. The ecosystem is available through The Health Developer Network.
