Human Subjects

The Human Subjects Committee (also known as the Institutional Review Board or IRB) assures that risks to human research subjects are minimized, consent is voluntary and informed, and confidentiality is protected. The Committee upholds the principles articulated in the Belmont Report and applies the regulations articulated in the Common Rule.

Amendment to the existing applications

If your research application is already approved in InfoReady and is still valid, you DO NOT need to submit a new application in Cayuse.

However, if your research application in InfoReady is expiring and needs an extension or amendment, you still need to submit a new INITIAL application in Cayuse at least 2 weeks before the expiration date.

The human subjects research records in InfoReady WILL NOT be transferred to Cayuse. To review your application, IRB reviewers need to review the full information to determine if your application can be approved.

Determine if you need IRB review:

To determine if your study, research or project requires Committee review, submit a request via Cayuse by clicking the Cayuse Human Ethics Log-In box above. The IRB Administrator will review the request to determine if the activity meets the definitions of ‘research’ and ‘human subjects’.

Once the IRB Administrator makes the determination, the determination form will be sent back to the requestor as official documentation.

*Renewal or Modification can be submitted only if the initial IRB application was approved in Cayuse. For all Renewals and Modifications to the initial IRB applications that were previously approved in InfoReady, please submit a New (Initial) Application/Protocol in Cayuse.


All researchers conducting human subjects research are required to complete training in the protection of human research participants via CITI Training. Review the CITI Training FAQs for any questions.

Report a problem

Researchers must report any incident that is unexpected (given the research procedures and population), may have been caused by the procedures involved in the research, and suggests that the research places subjects or others at a greater risk of harm (including physical, psychological, economic or social harm) than was previously known or recognized. In addition to adverse events/effects, you should also report any breaches of confidentiality and complaints about the study from subjects or staff.

If any such problem occurs, please take the following action:

  1. Attend to the safety and care of the research participant(s).
  2. Consider whether any more participants should be used in the research and consider immediately stopping the study until the occurrence is investigated.
  3. If the problem is serious (harmful, fatal or life threatening), report the event either orally or in writing to the Research Integrity and Compliance Officer within three days or call 605-688-5642

For all problems, submit the Incident-Complaint form through SDState InfoReady within 10 working days. The Research Integrity and Compliance Officer will review the report to follow up and take appropriate action.
