- How do I download all my project files from IRBNet to prepare for this transition to Cayuse?
-
In IRBNet, there is no shortcut to download all project documents at once. If you need to download all of a project documents, you may download them individually by navigating to the Designer page, using the blue, downward-facing arrow at the top of the page to open the Package Navigator, selecting All Documents, then downloading each document using the white piece of paper icon. You may wish to click the "Show All Versions" link if you need to download all versions of each document, rather than just the most recent version of each document. You can also view all project documents from the Submission Detail page by clicking on the All Project Documents; link above the "New and Revised Documents in this Package" table. Again, you may wish to toggle to the "Show All Versions" view, depending on which versions you'd like to download.
- I want to submit a modification/renewal/incident report/closure for a study that was approved in IRBNet. How do I transfer my approved protocols from IRBNet to Cayuse?
-
All approved IRBNet protocols have been transferred over as a "Legacy" study, which is a protocol shell that only includes the PI's name, study title, approval date, and expiration date. The PI is the only person who has access to the Legacy study, and it is the PI's responsibility to complete the Legacy submission with the approved study information. Please note that the information entered into the legacy submission must match the last IRB approved protocol that was submitted in IRBNet.
After the PI completes the Legacy submission, they will then have the ability to create a Modification, Renewal, Incident Report, or Closure submission. Primary contacts need to be added after the legacy submission is complete via a modification or renewal submission.
