Investigators who conduct research with human subjects now have access to the Cayuse IRB system for protocol submission and tracking. 

The Purdue University Human Research Protection Program (HRPP) worked over the summer to implement a new approach to protocol submission and processing. Effective Aug. 19, investigators who conduct research with human subjects will utilize a cloud-based software system, Cayuse IRB, to submit new protocols for review (accessed via www.irb.purdue.edu). Cayuse streamlines protocol submission communications between investigators and HRPP, provides researchers with immediate access to all of their protocol materials in real time, and offers significant advantages over previous submission approaches:

  • Cayuse provides users with a dashboard to track an application through the entire review process. HRPP anticipates that this will eliminate nearly all questions about review status, timelines and document receipt.
  • All submissions will be made online via Cayuse, with the ability to save submitted information at any time for future editing or retrieval. Within Cayuse, IRB application questions are presented in short-answer and multiple-choice formats. Consistent with the widely used online exemption determination system (PROPEL), the user interfaces within Cayuse to follow the review logic that fits various study types. This should eliminate some inefficiencies that result from use of the previous essay-style application approach.
  • When working with HRPP staff and IRB members, researchers can make any needed changes within the body of their protocol application using in-line commenting and corrections within Cayuse. Revisions will appear in relevant sections of the protocol application rather than in separate documents, memos or e-mails. Use of this approach will create a more conversational dialogue between investigators and the HRPP/IRB.
  • CITI training certification status will be imported directly from CITI to Cayuse for all Purdue University investigators. This will help eliminate the need for continuous manual cross-checking and uploading of separate training verifications documents. However, this automated step will only detect those in the CITI system who have connected their CITI accounts to their Purdue University Career Account (i.e., Purdue email address). This is an opportune time to ensure that all CITI accounts are linked to a Purdue University Career Account. Please see www.irb.purdue.edu/training or contact the HRPP office for assistance with this, as needed.

The Purdue HRPP asks for your help and patience as we now work with you to develop best practices in using Cayuse. Please look for information and increased training outreach during the transition. Note that only new protocol applications will be accepted via Cayuse IRB at this time. Applications that were submitted or reviewed by IRB prior to today will be considered “legacy protocols” and will only be converted for use within Cayuse on an as-needed basis (e.g., if study modifications are requested or protocol renewals are required). The HRPP anticipates having a process in place to amend legacy protocols via Cayuse by the end of October 2019. Please know that HRPP staff remain ready to assist you. For one-on-one assistance, please feel free to schedule an appointment or attend walk-in hours, as you prefer: www.irb.purdue.edu/contact.
