I do a lot of audits of investigator site files as part of site audits and consistently find the following issues:

1. Staff listed but not signed off as approved for the delgated tasks until after they have been working on the trial for a period of time (often several weeks)

2. Staff not listed at all, even though they have clearly performed study related tasks.

At close out meetings, these sites often ask me if I know of any systems they can out in place to ensure this doesn't happen in the future.

Has anyone come across any systems that stood out as an effective system for having control of these? If so, I would appreciate hearing of them. Thanks.
