Registration Links Amendments

All changes to demographic data via the Update Vision option on the PDS mismatch screen will automatically generate a registration links amendment message (AMS message). These messages will be sent to the NHAIS system along with any other amendments. You can monitor these outgoing amendments from the Daily Transactions section of the Transaction Management screen in the Registration Links module.

As part of the PDS update process, only those items that have changed will be transmitted to the PDS. Unchanged items will not be transmitted.

• If any elements of the address are changed, then the new address, in its entirety, will be transmitted to the PDS.
• The NHS Number is used as the key within PDS. Any local updates to the NHS Number break the link between the local record and the PDS record. Any updates which include a change to the NHS Number will not, therefore, be transmitted to the PDS. These changes will be resolved through the legacy Registration Links process.
