Element: id
Until such time as there is an approved and adopted national identifier for NHS staff it is recommended that the logical id is a locally issued employee/user identifier.
Such an identifier must be unique across the domain of the Acute Trust and not re-used by another member of staff after someone leaves as this could invalidate historic records.
If no suitable local staff identifier exists then consider using a UUID.
