Ethical Issues for Human Subjects Research: Ethical Issues for Human Subjects Research Role of IRBs


I. Purpose of Human Subjects Research: I. Purpose of Human Subjects Research Understand Disease Validate New Therapies Understand Physiological Processes Study Human Behavior Evaluate Curricular Changes Evaluate New Teaching Methods


Ethical Issues in Research: Ethical Issues in Research When using humans or animals for research, important ethical issues must be addressed Historically, these issues were addressed by the professional code of ethics Codes of conduct have evolved and now have been codified into law.


Ethical Issues in Research: Ethical Issues in Research World War II—The Nuremburg Trial Joseph Mengele and unethical experiments performed by Nazi doctors


Ethical Issues in Research: Ethical Issues in Research World War II-The Nuremburg Trial 20 doctors were charged with War Crimes and Crimes against humanity Joseph Mengele fled and was not tried Lead to Nuremburg Code of 10 Principles


Nuremburg Code: Nuremburg Code Requires voluntary consent Experiments must be rational Experiments must be based on animal studies and knowledge of the disease Experiments should avoid suffering No experiment should involve excessive risks, except in those studies where physical experimental physicians also serve as subjects


Nuremburg Code: Nuremburg Code Degree of risks should be determined by importance of the problem Precautions should be taken to avoid against even remote possibilities of injury, disability, or death Experiment should be conducted only by scientifically qualified persons Subjects should be able to end experiment at any time The scientist in charge must be prepared to terminate the experiment at any stage, if they believe the experiment is likely to result in injury, disability, or death to the subject


Ethical Issues in Research: Ethical Issues in Research Unfortunately, codes were not always followed: Tuskegee Syphilis Study-USPHS-1930’s Not treated even after penicillin discovered Jewish Chronic Disease Hospital Patients injected with cancer cells Midgeville State Hospital Investigational drugs used without consent


Ethical Issues in Research: Ethical Issues in Research Willowbrook State Hospital-1970 Retarded injected with viral hepatitis US Department of Energy-1950s-60s Studies on radioactive fallout University of Iowa-1940s Research on stuttering in orphans home Johns Hopkins-2001 Asthma study with hexamethonium


National Research Act: National Research Act Increased Public concern led to congressional action and National Research Act of 1974 President Nixon then established National Commission for the Protection of Human Subjects of Biomedical and Behavioral research Commission charged to consider: Boundaries between practice and research Assessment of role of risk vs. benefit in research Guidelines for selection of subjects Informed Consent


Belmont Report: Belmont Report National Commission submitted the Belmont Report to President in 1979 Led to 1981 revision of 1974 guidance (45 CFR 46) for human research committees 45 CFR 46-has become the bible for reviewing research funded by DHHS Required appointment of Institutional Review Boards or IRB’s to review human subject studies Provided standards for appointment of IRBs, record-keeping and oversight in research


45 CFR 46: 45 CFR 46 Revised in 1983 and 1991 In 1991 revisions referred to as Common Rule Adopted by 15 federal agencies, not just DHHS Institutions with NIH funding must submit assurance of compliance to OHRP, DHHS After February 28, 2001-assurances must cover all research at institution, not just NIH


II. Institutional Review Boards: II. Institutional Review Boards Makeup of IRB At least 5 members Male/Female Professionals/laypersons External “non-affiliated” member Must represent community Lay person must be at meeting for reviews


II. Institutional Review Boards: II. Institutional Review Boards IRB’S must be guided by principles outlined in Belmont Report: Respect for persons: respect for patient autonomy Beneficence: maximize benefits and minimize harm Justice: Equitable distribution of research burdens and benefits


III. IRB Review of Research: III. IRB Review of Research Three categories of Review: Exempt Expedited Full Review


IRB Review of Research: IRB Review of Research Exempt-by Chair or Administrator Research in educational settings involving normal educational practices Instructional strategies Effectiveness of instructional techniques Comparison of techniques or curricula, etc.


IRB Review of Research: IRB Review of Research Exempt-by Chair or Administrator Research involving educational tests (cognitive, diagnostic, aptitude) Unless Names or identifiers are recorded and Disclosure could put subject at risk of criminal liability or affect employability


IRB Review of Research: IRB Review of Research Exempt-by Chair or Administrator Survey research without identifiers; interviews, observation of public behavior Unless Names or identifiers are recorded and Disclosure could put subject at risk of criminal liability or affect employability


IRB Review of Research: IRB Review of Research Exempt-by Chair or Administrator Collection or study of existing data, documents, records, pathological or diagnostic specimens If the sources are publicly available, or If information is recorded so that the subject cannot be identified, directly or indirectly


IRB Review of Research: IRB Review of Research Exempt-by Chair or Administrator Research and demonstration projects conducted by or subject to approval by DHHS to study, evaluate or examine: Public benefit or service programs Procedures for obtaining benefits or services from these programs Other changes in these programs Taste and food quality evaluation and consumer acceptance studies


IRB Review of Research: IRB Review of Research Expedited Review Research activities reviewed by Chair or designee Two cautions however: Only for activities involving minimal risk-i.e., no more risks than those in everyday life Cannot be used if subject responses might pose civil or criminal risk to subject, unless Reasonable protections can be implemented so that risks related to invasion of privacy and breach of confidentiality are minimal


IRB Review of Research: IRB Review of Research Expedited Review-Categories eligible Some studies of approved drugs or devices Collection of blood from adults Not to exceed 550mL in 8 weeks Not more often than 2 times per week Collection of specimens by non-invasive means: sweat, excreta, amniotic fluid, hair, teeth, plaque


IRB Review of Research: IRB Review of Research Expedited Review-Categories eligible Collection of data through non-invasive means, excluding X-ray and microwave EKG, ECG, MRI, weighing, thermography, ultrasound, doppler blood flow, exercise, flexibility testing, etc. Research involving data, records, specimens collected, or that will be collected solely for non-research purposes Collection of voice, video, digital, or images made for research purposes


IRB Review of Research: IRB Review of Research Expedited Review-Categories eligible Research on individual or group characteristics or behavior including: Perception, cognition, motivation, identity, language, communication, beliefs or practices, etc. Research involving surveys, interview focus groups, program evaluations, or quality assurance methods Continuing reviews for previously approved projects Minor changes in previously approved research


IRB Review of Research: IRB Review of Research Full Review-Full Committee Investigational drugs, devices, invasive techniques (PET scan), implants, etc. Higher risk research NOTE-research not approved by IRB cannot be approved by higher authorities, however approved research may be disapproved by higher authorities


IV. IRB Approval: IV. IRB Approval To be approved: Risks must be minimized by sound research design Risks must be reasonable in relation to benefits Selection of subjects must be equitable Informed consent will be sought from each subject


IRB Approval: IRB Approval To be approved-continued: Informed consent will be appropriately documented When appropriate, research plan must ensure continued safety of subjects Where appropriate, provisions made to protect privacy of subjects and data When working with subjects vulnerable to coercion, must consider added safeguards


Continuing Review: Continuing Review For research continuing more than one year, an annual review is required New standards under review: Will probably require IRB monitoring of some clinical trials Constant assessment of conflict of interest of the investigators


Informed Consent: Informed Consent Not needed for exempt studies Required for Expedited Review-but may be simplified for low risk studies Rigorous consent for Full Review projects May be waived by IRB for emergency Medicine research-controversial issue


Informed Consent: Informed Consent Consent must address critical elements or points outlined by Federal Law Consent signed by subject or legal representative and investigator Subject must be given copy of consent No exculpatory language may be used in the written consent


Basic Elements of Consent: Basic Elements of Consent Explanation of purpose and duration Description of risks Description of benefits Disclosure of alternatives to participation


Basic Elements of Consent: Basic Elements of Consent Explanation of Confidentiality of Records Who to contact regarding patient rights For research with more than minimal risks, comment on compensation and care for injury Right to withdraw without prejudice Statement regarding unforeseen risks, especially to unborn child


Additional Elements for Consent: Additional Elements for Consent Statement that investigator may terminate patient participation Information regarding any costs Statement regarding consequences of withdrawing-especially for drug studies Number of subjects in study


Special Populations-Children: Special Populations-Children Special Considerations Children are persons who have not attained the legal age for consent to treatments or procedures involved in research Research not involving greater than minimal risk may be approved: With assent of the child and permission of parents


Special Populations-Children: Special Populations-Children Special Considerations Research involving greater than minimal risk and the prospect of direct benefit to the child may be approved: If the risk is justified by the anticipated benefit The relation of the benefit to risk is at least as favorable to subjects as the alternative approaches With assent of the child and permission of parents


Special Populations-Children: Special Populations-Children Special Considerations Research involving greater than minimal risk and no prospect of direct benefit to the child may be approved: If the risk represents a minor risk over minimal risk If the intervention presents experiences that are reasonably similar to those in actual medical, dental, social, psychological, or educational situations If the intervention is likely to yield generalizeable knowledge about the disorder or condition With assent of the child and permission of parents


Special Populations-Children: Special Populations-Children Special Considerations Assent of the child Usually verbal-confirmed by parents “Assent” cam usually be provided by children over six years of age-but varies based on maturity and psychological state Failure to object should not, absent affirmative agreement, be construed as assent


Special Populations-Prisoners: Special Populations-Prisoners Special Considerations IRB membership Majority of members must have no association with the prison Must include a prisoner, or prisoner representative with experience to serve in this capacity


Special Populations-Prisoners: Special Populations-Prisoners Special Considerations The research may be approved if: The advantages of participation are not “enticing” or prohibit good judgment Risks are similar to those for non-prisoner research Consent is understandable to prison population Decision to participate will not affect parole


Special Populations-Prisoners: Special Populations-Prisoners Special Considerations Permitted Research: Study of causes, effects, or processes involving incarceration Study of prisons as institutional structures or of prisoners as incarcerated persons Study of conditions affecting prisoners as a class Vaccine trials for diseases prevalent in prisons Study of social behavior of prison population

Nuremburg Code: Nuremburg Code The voluntary consent of the human subject is absolutely essential The experiment should be such as to yield fruitful results for the good of society, unprocurable by other methods or means of study, and not random and unnecessary in nature. The experiment should be so designed and based on the results of animal experimentation and a knowledge of the natural history of the disease or other problem under study, that the anticipated results will justify the performance of the experiment. The experiment should be so conducted as to avoid all unnecessary physical and mental suffering and injury.


Nuremburg Code: Nuremburg Code No experiment should be conducted, where there is an a priori reason to believe that death or disabling injury will occur; except, perhaps, in those experiments where the experimental physicians also serve as subjects. The degree of risk to be taken should never exceed that determined by the humanitarian importance of the problem to be solved by the experiment. Proper preparations should be made and adequate facilities provided to protect the experimental subject against even remote possibilities of injury, disability, or death.


Nuremburg Code: Nuremburg Code The experiment should be conducted only by scientifically qualified persons. The highest degree of skill and care should be required through all stages of the experiment of those who conduct or engage in the experiment. During the course of the experiment, the human subject should be at liberty to bring the experiment to an end, if he has reached the physical or mental state, where continuation of the experiment seemed to him to be impossible. During the course of the experiment, the scientist in charge must be prepared to terminate the experiment at any stage, if he has probable cause to believe, in the exercise of the good faith, superior skill and careful judgment required of him, that a continuation of the experiment is likely to result in injury, disability, or death to the experimental subject.
