Introduction to Demographics Update Event Messages


This implementation guide outlines the structure and content of the following PDS Demographics Update event messages:

These event messages are constructed and published by the Spine when updates are made to the patient demographic information held by the Personal Demographics Service (PDS). The event messages will be published to the NEMS for the purpose of sharing updates with interested subscribers.


FHIR components specified within this site have been developed by NHS Digital and use CareConnect profiles created in collaboration with the INTEROPen community.

The INTEROPen vision is to create a library of nationally defined HL7® FHIR® resources and interaction patterns that implementers can adopt to simplify integration and interoperability within UK health and social care.

See CareConnect FHIR Profiles for further clarification on the use of CareConnect FHIR profiles within this Implementation Guide.
