Alterations or Waiver of Informed Consent

version February 2025

Waiver of one or more elements of consent is permitted provided that the research is no more than minimal risk and meets specific criteria. Waiver of an element of consent appropriate if one or more of the required elements is not relevant to the research activity. Complete waiver of consent is also permitted; this is most frequently granted for retrospective research but is also possible for some types of prospective research.


PER 45 CFR 46.116(d)

An IRB may approve a consent procedure which does not include, or which alters, some or all of the elements of informed consent set forth in this section, or waive the requirement to obtain informed consent provided the IRB finds and

documents that:


*The research involves no more than minimal risk to the subjects;

*The waiver or alteration will not adversely affect the rights and welfare of the subjects;

*The research could not practicably be carried out without the waiver or alteration; and

*Whenever appropriate, the subjects will be provided with additional pertinent information after participation.
