View Full Version : FDA 21 CFR Part 11 - Electronic Signatures and Gait Files

Dear All

I have an intriguing problem with which you may be able to help.

I need to inlcude some of our gait files in a study to be submitted at
sometime in the future to the FDA - and being a 'computerised system' the
files need to have electronic signatures.

The guidance is clear that I need to run a system that requests the
signature BEFORE the data capture. But the system we run has no such
facility.

I was proposing to encrypt the files immediately AFTER capture -
appropriately signed and time-stamped but our QA people say that is too
late.

Has anyone had to face this problem?

If so, how have you added electronic signatures 'retrospectively'?

Many thanks
