This was included in the e-service procurement as an optional element but it has not been taken up at this time. However, we believe that the e-service lays the ground as each user will be issued with a SHL ID. Where a service user attends a clinic, staff will be able to check if they have an e-service record and their SHL ID could be copied into the local clinic software for future reference. While this provides a London-wide identifier, it does not provide a London-wide patient record.
