It has been suggested that IRB: Ethics & Human Research be merged into this article. (Discuss) Proposed since November 2014. |
An institutional review board (IRB), also known as an independent ethics committee (IEC), ethical review board (ERB) or research ethics board (REB), is a committee that has been formally designated to approve, monitor, and review biomedical and behavioral research involving humans. They often conduct some form of risk-benefit analysis in an attempt to determine whether or not research should be done.[1]
The purpose of the review process is to assure, both in advance and by periodic review, that appropriate steps are taken to protect the rights and welfare of humans participating as subjects in a research study. A key goal of IRBs is to protect human subjects from physical or psychological harm, which they attempt to do by reviewing research protocols and related materials. The protocol review assesses the ethics of the research and its methods, promotes fully informed and voluntary participation by prospective subjects capable of making such choices (or, if that is not possible, informed permission given by a suitable proxy), and seeks to maximize the safety of subjects.
In the United States, the Food and Drug Administration (FDA) and Department of Health and Human Services (specifically Office for Human Research Protections) regulations have empowered IRBs to approve, require modifications in planned research prior to approval, or disapprove research. IRBs are responsible for critical oversight functions for research conducted on human subjects that are "scientific," "ethical," and "regulatory."
IRBs are most commonly used for studies in the fields of health and the social sciences, including anthropology, sociology, and psychology. Such studies may be clinical trials of new drugs or devices, studies of personal or social behavior, opinions or attitudes, or studies of how health care is delivered and might be improved.
The equivalent body responsible for overseeing U.S. federally funded research using animals is the Institutional Animal Care and Use Committee (IACUC).
Formal review procedures for institutional human subject studies were originally developed in direct response to research abuses in the 20th century. Among the most notorious of these abuses were the experiments of Nazi physicians, which became a focus of the post-World War II Doctors' Trial, the Tuskegee Syphilis Study, a long-term project conducted between 1932 and 1972 by the U.S. Public Health Service, and numerous human radiation experiments conducted during the Cold War. Other controversial U.S. projects undertaken during this era include the Milgram obedience experiment, the Stanford prison experiment, and Project MKULTRA, a series of classified mind control studies organized by the CIA.
The result of these abuses was the National Research Act of 1974 and the development of the Belmont Report, which outlined the primary ethical principles in human subjects review; these include "respect for persons", "beneficence", and "justice." An IRB may only approve research for which there is a bona fide informed consent process for participants, for which the risks to subjects are balanced by potential benefits to society, and for which the selection of subjects presents a fair or just distribution of risks and benefits to eligible participants.
In the United States, IRBs are governed by Title 45 Code of Federal Regulations Part 46.[2] These regulations define the rules and responsibilities for institutional review, which is required for all research that receives support, directly or indirectly, from the United States federal government. IRBs are themselves regulated by the Office for Human Research Protections (OHRP) within the Department of Health and Human Services (HHS). Additional requirements apply to IRBs that oversee clinical trials of drugs involved in new drug applications, or to studies that are supported by the United States Department of Defense.
In addition to registering its IRB with the OHRP, an institution is also required to obtain and maintain a Federalwide Assurance or FWA, before undertaking federally funded human research.[3] This is an agreement in which the institution commits to abiding by the regulations governing human research. A secondary supplement to the FWA is required when institutions are undertaking research supported by the U.S. Department of Defense.[4] This DoD Addendum includes further compliance requirements for studies using military personnel, or when the human research involves populations in conflict zones, foreign prisoners, etc.[5]
Numerous other countries have equivalent regulations or guidelines governing human subject studies and the ethics committees that oversee them. However, the organizational responsibilities and the scope of the oversight purview can differ substantially from one nation to another, especially in the domain of non-medical research. The U.S. Dept of Health and Human Services maintains a compilation of regulations and guidelines in 96 countries, as well as related standards from a number of international and regional organizations.[6]
Although "IRB" is a generic term used in the United States by the FDA and HHS, each institution that establishes such a board may use whatever name it chooses. Regardless of the name chosen, the IRB is subject to the FDA's IRB regulations when studies of FDA-regulated products are reviewed and approved. At one time such a committee was named the "Committee for the Protection of Human Subjects". Originally, IRBs were simply committees at academic institutions and medical facilities to monitor research studies involving human participants, primarily to minimize or avoid ethical problems. Today, some of these reviews are conducted by for-profit organizations known as 'independent' or 'commercial' IRBs. The responsibilities of these IRBs are identical to those based at academic or medical institutions, and they are governed by the same U.S. federal regulations.
The regulations set out the board's membership and composition requirements, with provisions for diversity in experience, expertise, and institutional affiliation. For example, the minimum number of members is five, and they must include both men and women, at least one scientist, and at least one non-scientist. The full requirements are set out in 21 CFR 56.107.[7]
Unless a research proposal is determined to be exempt (see below), the IRB undertakes its work either in a convened meeting (a "full" review) or by using an expedited review procedure.[8] When a full review is required, a majority of the IRB members must be present at the meeting, at least one of whom has primary concern for the nonscientific aspects of the research.[8] The research can be approved if a majority of those present are in favor.[8]
An expedited review may be carried out if the research involves no more than minimal risk to subjects, or where minor changes are being made to previously approved research.[9] The regulations provide a list of research categories that may be reviewed in this manner.[9] An expedited review is carried out by the IRB chair, or by their designee(s) from the board membership. Research activity cannot be disapproved by expedited review.[9]
The International Conference on Harmonisation sets out guidelines for registration of pharmaceuticals in multiple countries. It defines Good Clinical Practice, which is an agreed quality standard that governments can transpose into regulations for clinical trials involving human subjects.[10]
Here is a summary of several key regulatory guidelines for oversight of clinical trials:
The reviewers may also request that more information be given to subjects when, in their judgment, the additional information would add meaningfully to the protection of the rights, safety and/or well-being of the subjects. When a non-therapeutic trial is to be carried out with the consent of the subject's legally acceptable representative, reviewers should determine that the proposed protocol and/or other document(s) adequately address relevant ethical concerns and meets applicable regulatory requirements for such trials. Where the protocol indicates prior consent of the trial subject or the subject's legally acceptable representative is not possible, the review should determine that the proposed protocol and/or other document(s) adequately addresses relevant ethical concerns and meets applicable regulatory requirements for such trials (i.e., in emergency situations).
U.S. regulations identify several research categories that are considered exempt from IRB oversight. These categories include:
Generally, human research ethics guidelines require that decisions about exemption are made by an IRB representative, not by the investigators themselves.[12]
While the Belmont principles and U.S. federal regulations were formulated with biomedical and social-behavioral research in mind, the enforcement of the regulations, the examples used in typical presentations regarding the history of the regulatory requirements, and the extensiveness of written guidance have been predominantly focused on biomedical research.
Numerous complaints by investigators about the fit between the federal regulations and its IRB review requirements as they relate to social science research have been received. Broad complaints range from the legitimacy of IRB review, the applicability of the concepts of risk as it pertains to social science (e.g., possibly unneeded, over-burdensome requirements), and the requirements for the documentation of participants' consent, i.e., consent forms). Social scientists have criticized biomedical IRBs for failing to adequately understand their research methods (such as ethnography). In 2003, the Office for Human Research Protections (OHRP), in conjunction with the Oral History Association and American Historical Association, issued a formal statement that taking oral histories, unstructured interviews (as if for a piece of journalism), collecting anecdotes, and similar free speech activities often do not constitute "human subject research" as defined in the regulations and were never intended to be covered by clinical research rules.[13]
Other federal agencies supporting social science have attempted to provide guidance in this area, especially the National Science Foundation. In general, the NSF guidelines assure IRBs that the regulations have some flexibility and rely on the common sense of the IRB to focus on limiting harm, maximizing informed consent, and limiting bureaucratic limitations of valid research.[14]
While the IRB approval and oversight process is designed to protect the rights and welfare of the research subjects, it has been the subject of criticism, by bioethicists and others, for conflicts of interest resulting in lax oversight.[15][16] In 2005, the for-profit Western Institutional Review Board claimed to conduct the majority of reviews for new drug submissions to the FDA.[17] In a 2006 study of 575 IRB members at university medical centers, over one-third reported industry financial ties and over one-third admitted they "rarely or never" disclosed conflicts of interest to other board members.[18] A 2009 sting operation by the Government Accountability Office led Coast IRB to shut down after approving the fake product "Adhesiabloc", called "the riskiest thing I’ve ever seen on this board" by one of the IRBs not approving the fake product.[19][20][21][22][23]
