The below information and processes are taken directly from or guided by the regulatory requirements, state laws and institutional polices. If you do not find the answer to your question below, please contact an IRB Coordinator.
Getting Started with Institutional Review Board (IRB) Approval
Q. What types of projects require IRB approval?
In order for a project to require oversight by the IRB it must meet the regulatory definitions of research AND human subjects. Policy #3.001, “Investigational Activities Requiring IRB Review and Approval” defines activities that must be reviewed and approved by the IRB before the project begins (including recruitment).
- Research is “a systematic investigation, including research development, testing, and
evaluation, designed to develop or contribute to generalizable knowledge.”
- Human subject is “a living individual about whom an investigator (whether professional or student) conducting research obtains, 1) data through intervention or interaction with the individual, or 2) identifiable private information (including data or tissues)”
Q. Who can make the decision of whether I need to get IRB approval?
The decision of whether or not you are conducting human subjects research can be made by the Principal Investigator and whether or not an application for IRB review must be submitted. According to Policy #3.001 titled, “Investigational Activities Requiring IRB Review and Approval” section 3.3 specifies, “Any individual who is unsure whether or not a proposed activity constitutes “research involving human subjects” should contact the HRPP office for guidance.”
Q. What happens if I make the wrong decision?
If the wrong decision is made and IRB approval is required, it may not be granted if the research has already started or been conducted and the determination of IRB applicability was made incorrectly by the investigator.
If you are unsure whether your project requires approval, please review the definitions above or the Human Subject Regulations Decision Charts available through the Office of Human Research Protections.
If your project does require IRB approval, the decision charts may not be used for exemption determinations, expedited review, or continuing review. Certain state laws and institutional policies, not taken into account within the decision charts, may affect review categories and applicability.
Q. When am I required to submit an IRB application?
All proposed research projects involving the use of human participants conducted under the auspices of the University of Nebraska-Lincoln are to be submitted for IRB review BEFORE the research begins. This includes recruitment of study subjects.
Q. I am just doing a simple survey; do I need to submit to the IRB?
Yes, if the survey meets the definitions discussed above. UNL’s Assurance with the Department of Health and Human Services says all research conducted under the auspices of this institution will undergo the IRB review and approval process.
Q. I believe my protocol is exempt. Does it need to be reviewed?
Yes. It is the policy of the UNL IRB that all proposed exempt research is reviewed by the Human Research Protection Program (HRPP) staff for final determination of review level.
Q. I am not collecting any identifying information from a human subject; do I need to file for approval?
Yes. Federal regulations and UNL regulations require that ALL research obtaining information from human subjects either through interaction and/or intervention be submitted for review.
Q. I am only working with previously collected data; do I need to file for approval?
It depends. Federal regulations require that if the study will use either existing or to-be-collected data, documents, records, pathological specimens or diagnostic specimens from human subjects, must be submitted for review.
Q. My research is based on de-identified tissue samples; do I need to file for approval?
It depends. Research involving the study of existing pathological specimens from participants who cannot be identified, directly or through identifiers linked to the participants, may qualify for an exemption determination or may not be considered human subjects research. For it qualify for an exemption determination, all of the de-identified specimens must exist prior to the start of the research project for this to apply. These determinations can be complex, we encourage you to contact an IRB Coordinator at the earliest possibility to discuss your project.
Q. I will be collaborating with a researcher at another institution; do I need to file for IRB approval at both UNL and the other institution?
Investigators should contact an IRB staff person whenever collaborative or multi-institutional research is planned. Separate applications may be necessary, or an IRB Authorization Agreement may be reached with the other institution. However, this is the decision of the UNL Institutional Official. The Principal Investigator or study staff do not have the authority to enter into agreements or pledge IRB resources (including review) on behalf of the IRB with other institutions or collaborating researchers.
Q. Should I wait until my research proposal has been funded to submit a protocol for IRB approval?
You can wait, but it is best to submit your IRB application soon after your research proposal is submitted to the sponsor. Some sponsors provide only a small window of opportunity to provide the IRB approval materials and you will want to be as prepared as possible when your proposal is funded.
Before/During the Review Process …
Q. How do I submit my application for IRB approval?
All IRB protocols should be submitted through NUgrant. The NUgrant system is easy to use and leads you through the application process step-by-step. You may be asked to upload certain files to accompany your application, such as measures used in the study (surveys, questionnaires, interview questions, etc), recruitment materials (flyers, e-mails, letters, scripts, etc), informed consent/assent forms, grant proposals, approval letters, follow-up materials, etc.
Q. How long does it take to review an application for IRB approval?
Review times vary. The length of time depends on the IRB, the investigator and the review level or complexity of the project. At certain times of the year, a large volume of protocols appear in the reviewing queue. All forms are reviewed on a first-come-first serve basis. More complex protocols often take more time and could involve multiple offices outside of Research Compliance Services increasing additional time for final approval to occur.
Q. Who is required to complete the human participants (CITI) training?
All faculty, students, and staff proposing to use human participants in research under the auspices of UNL are required to complete the human participants training offered through CITI. IRB approvals of a proposed research project will be not be granted until this training has been completed and verified.
Q. What if I am only entering data? Do I have to take the whole CITI training?
A provision in the CITI curriculum allows limited research workers to take an abbreviated version to fulfill the training requirement. Limited research workers must meet ALL of the following conditions to be eligible for abbreviated training: 1) no responsibilities in project design; 2) not enrolled as a graduate student at UNL; 3) not UNL faculty; AND must meet at least ONE of the following conditions: 1) very limited independent decision-making in study implementation and data collection; and 2) no role in data collection, but may have access to participant identity and confidential data.
After Approval is Granted …
Q. When should I submit a request to modify an approved protocol?
All changes to an approved protocol are to be submitted for review and approval before you incorporate the changes into the research project except when an immediate change is necessary to eliminate a hazard to the participants as required under 45 CFR §46.103(b)(4).
Changes could include but not limited to, changing surveys/questionnaires, adding participants, sampling a different participant population, a title change, change in principal investigator, change of funding source, increased time for participant participation, etc.
More information about changes and how they are reviewed can be found in Policy #12.001, titled, “Request for Change.”
Q. What do I have to do if I need to amend my approved protocol?
All requests for changes must be made through NUgrant via submission of a change request application.
Q. Does approval of a modification for an approved protocol extend the original approval date?
No. The expiration date of the original approval is not changed by the review and approval of a modification.
Q. How do I renew my project for continued approval?
The principal investigator is responsible for ensuring the continued approval of research projects involving human participants. To remind you of this obligation, approximately two months before the approval expires, you will begin receiving notices via e-mail that you need to file for continuing review if you plan to continue this research beyond the one-year approval period.
Q. In the case of an adverse event, unanticipated problem or non-compliance, when am I expected to report this occurrence to the IRB?
The Principal Investigator should report any adverse events, unanticipated problems or non-compliance within 48 hours of when any of the research team members become aware of the incident. A comprehensive list of examples and definitions can be found in Policy #13.001 titled, “Unanticipated Problems Involving Risk and Adverse Events” and Policy #14.001, titled, “Non-compliance.”
Q. Can the IRB temporarily or permanently discontinue a research project as result of an adverse event, unanticipated problem or noncompliance?
Yes. If an adverse event, unanticipated problem, or non-compliance poses an unexpected risk to the participants, or creates an unmanageable issue related to human subjects protection, the IRB may temporarily discontinue a research project until a thorough investigation has been conducted. Depending on the results of the investigation, the IRB may request changes to a research project or permanently discontinue the research project.
