Hello Kirsten,

When updating a review in EPPI-Reviewer I would deal with the new references separately with respect to creating coding assignments rather than trying to include them in existing assignments.

You could have an administration codeset with codes to identify the new items. Once they are easily identifiable you can then create new allocation codes and new coding assignments that only contained the new items. This would avoid the issue of having to make any changes to any of your existing coding (such as marking them all as 'not complete').

There is a danger in marking all of your previous items as 'not complete' because if those items were double screened/coded you will not know which reviewers coding was the agreed version when you return them to 'complete'.

Best regards,

Jeff
