Effective Date: December 9, 2022
Case Report: For IRB purposes, a single case report is a retrospective analysis of one, two, or three clinical cases.
Investigator: Department of Health and Human Services (HHS) guidance uses the term “investigator” to refer to an individual performing various tasks related to the conduct of human subjects research activities, such as obtaining informed consent from subjects, interacting with subjects, and/or studying, interpreting, or analyzing identifiable subject data.
Principal Investigator (PI): The “principal investigator” holds overall responsibility for the study. The Principal Investigator is responsible for the submittal of the proposed protocol, ethical design and conduct of protocol activities, and supervision of all study personnel.
A single retrospective case report is a medical and/or educational activity and does not meet the Federal Policy for the Protection of Human Subjects definition of "research." HHS regulations define research as “a systematic investigation, including research development, testing and evaluation, designed to develop or contribute to generalizable knowledge.”
Case reports involving one, two, or three participants, with no prior research intent typically do not require SIUC Institutional Review Board (IRB) review. A protocol may require IRB review if it meets any of the following criteria:
Formal determinations can only be issued if the investigator submits an IRB application. Upon review, if a retrospective analysis of one, two, or three case reports does not meet the criteria outlined in the policy, the IRB will issue a formal determination classifying the project as a case report. If, upon review, the project meets any of the above criteria, the IRB will review the submission as human subjects research. Investigators are encouraged to contact the IRB with any questions about whether a project requires review.
