OpenSpecimen allows users to add existing participants to another protocol using EMPI or MRN + MRN site or SSN.

E.g., Register a participant having eMPI ‘MPI18415’ (already present in CP ‘MES-PW’) to another CP ‘AQ - DO NOT TOUCH’.

Steps:

• Navigate to the 'Collection Protocols' list page → More → ‘Biospecimen Data’.

• Select 'Participant Registrations’ from the 'Select Records Type' dropdown and download the template file from UI.

• Add the existing EMPI of the participant under the respective column in the template file.
• Add a short title and PPID (if auto-generation is off) of another CP on which the user is going to register the participant in the columns ‘CPR#1#CP Short Title’ and ‘CPR#1#PPID’ respectively.

Example CSV: cprMultiple.csv

• Upload the file and select ‘Import Type’ as ‘Update’ → ‘Validate and Import’.

• The system will register the participant to another CP using the existing eMPI.
