Does the sponsor need to know the individual who they are approving access rights for (e.g. would a pharmacist sponsor need to know the technician they are sponsoring)?
No. It is not necessary for the sponsor to know the individual they are approving access rights for. The sponsor must reassure themselves that the user requires the level of access requested; therefore if they do not know the individual, they may need to contact the pharmacist in charge of the pharmacy to confirm with them that the individual requires the requested level of access.
