In some situations, the IRB can waive the requirement that research subjects sign an Authorization Form. To qualify for a Waiver of Authorization, the research use of the health information should not represent more than a minimal risk to privacy, and the researcher should indicate that the research could not be done without the requested health information, that it would not be practical to obtain signed authorizations from the research subjects, and that the specific elements of health information that are requested are not more than the minimum necessary to accomplish the goals of the study.
Occasionally there are reasons to waive written consent or to alter the requirements of consent. Only the IRB can make the determination to waive some (written) or all (written and verbal) consent requirements. In order to qualify for a Waiver of Consent, the following conditions should be met: 1) that the research pose no more than minimal risk to subjects; 2) no adverse effects as a result of the waiver or alteration; 3) without the waiver or alteration the research in question could not be carried out; and 4) information will be provided after participation is completed, if appropriate.
