Update study settings during the study conduct period

You can edit all study settings at any time, but use caution when changing the subject numbering fields, particularly if subjects have already been screened. Updating these fields could result in inconsistent subject numbers. This also applies to subjects who are enrolled in a rollover study and keep their original study ID. Changing their number might result in inconsistencies when it comes to subject numbers in your rollover study.

The subject numbering fields are:

• Include Hyphen in Subject Numbers
• Leading Zeros in First Subject Number
• First Subject Number
• Subject Numbering
  • If you change to a higher value mid-study, there will be a gap in the subject numbers.
  • If you change to a lower value mid-study, you don't have to worry about duplicate subject numbers because subject numbers are never reused.
