The Demographics Batch Service (DBS) is a mechanism that allows NHS and other organisations to submit a file of patient information to the Spine for tracing against the Personal Demographics Service (PDS). 

The DBSB provides a mechanism for non-PDS compliant organisations to perform batch tracing of demographic records against the PDS and identify and return the NHS Number associated with these records.

The Bureau will take receipt of a properly formatted batch trace file and submit it for processing through DBS on behalf of the service user.

All data will be transmitted and managed with appropriate security through the end-to-end process.

More information about this service and how to access it can be found in DBSB – NHS Number Tracing.
