lists and definitions research ethics Flashcards
Vivisection (Lederer):
Cutting into live organism
Human vivisection (Lederer):
experiments on humans not to benefit the individual but to gain medical information (used up to 1930s)
Justification of human subjects research (Jonas)
- Access to goods research
- Justified by social contract theory
- Need for public good = duty (our only duty maintenance of current state)
Rule of Descending order (Jonas)
- Pts id with and are aware of the cause of research (med professional)
- Highly educated
- Least dependent
- Those serious illness always last
4 Stages of Research
- Toxicity
- Efficacy and safety small #
- Large number of participants
- Post-marketing surveillance trials
Good choice study (Wertheimer):
Person could probably participate for self-interested reasons because of expected benefits to herself
Bad choice study (Wertheimer):
Person can’t expect net positive benefits to herself, not in medical interest
Equipoise:
No reason to think on intervention is more efficacious than the other
Research:
Activity to test hypothesis, draw, conclude, contribute to generalizable knowledge
3 Principles govern human subjects research (Belmont Report)
- Respect for persons - autonomy, protection depends on degree of risk
- Beneficence
- Justice - burdens/benefits research on populations
Requirements from belmont report
- Informed consent (information, comprehension, voluntariness)
- Assessment of risks and benefits (nothing brutal, reduce risks, be more cautious as risks increase, more cautious on vulnerable population, include risks and benefits on forms)
- Selection of subjects (individual justice, all equal chance to participate, social justice, no group bears disproportionate burden
7 principles ensure research is ethical (Emanuel, Wendler, Grady)
- Social/scientific validity
- Scientific validity
- Fair subject selection
- Favorable risk-benefit ratio
- Independent review
- Informed consent
- Respect pts
4 Requirements informed consent
- Competent
- Voluntary
- Informed
- Comprehending
What Empirical research reveals about informed consent (Candilis)”
- Give info in parts
- Education improves dmc
- Written material and pics
- People can’t guess wishes of another person
- Physicians underestimate pt competence and satisfaction with informed consent
- People can’t understand risks, benefits, or standards
- Therapeutic misconception
3 Theories of autonomy (Beauchamp)
- Autonomous person theories - emphasize agent
- Autonomous action - acting intentionally with understanding
- Split level theories - consists of capacity to control - identify with one’s first order desires by means of second order desires
Theory of autonomy (Beauchamp)
- Intentional
- Understanding
- Voluntary
Consent Transaction (Wertheimer, Miller):
Interaction between 2 people allow A to do X to B, question is if consent creates moral transformation both parties
Lock and Key/Autonomous Authorization model (Wertheimer, Miller):
Valid consent is necessary and sufficient for moral transformation valid consent is key opens lock to moral transformation
Fair Transaction Model (Wertheimer, Miller):
A can proceed on basis of B’s consent if A has treated B fairly and responds reasonably to B’s expression of consent if consent is flawed but fair, it is allowable (authorizes consent even with therapeutic misconception)
2 Reasons to defend soft paternalism (Wertheimer)
- Depends on valid/reasonable judgment, decisional defect impair voluntary consent
- Numerous good reasons eschew paternalistic influence with competent adults even if decision-making is impaired
7 ethical requirements in clinical research (Emmanuel)
- Social value
- Scientific validity
- Far subject selection
- Favorable risk benefit
- Independent review
- Informed consent
- Respect subjects
Decisional deficits make difficult for competent adults protect interests
- Lack scientific/clinical knowledge
- Prospective subjects suffering from disease vulnerable therapeutic misconception
- Pt-subjects who desperate for chance medical benefit from access experimental treatment over estimate benefit
Soft paternalism:
Limits liberty on grounds person’s decision making is impaired
Hard Paternalism:
Limits liberty someone decision making NOT impaired
Direct Paternalism:
Limits liberty of person whose interest and we are trying to protect
Indirect Paternalism:
Limit liberty one person to offer choices to another to protect interests of latter
Types of Review
- Exempt
- Expedited (only 1 reviewer)
- Full Board (more than minimal risk research)
Types of Approval:
- Full approval
- Approval with contingencies (most)
- Tabled/deferred
- Disapproved
Sources Variability in IRBS (Pritchard)
- Local circumstances
- Members unaware some facts relevant to assessment
- Members differ in their application of regulatory provisions
- Varying levels support to IRB
- Legitimate differences in moral perspective
Rational choice theory (Pritchard):
People seek good and avoid bad
Risk Preference (Pritchard):
easily manipulated by language
Maximizers (Pritchard):
Review all possible options making a decision
Satisfiers (Pritchard):
Willing choose an option when looks ‘good enough’
Minimal Risk Research:
Probability and magnitude of harm/discomfort anticipated in research not greater than risks ordinary life
Signal Potential (Slovik):
People perceive things without statistical risk but large impact like nuclear power plants as riskier than everyday events that are statically risky like car travel
SERR (Systematic evaluation of research risks) (Rid, Emanuel, Wendler)
- ID potential harms
- Categorize magnitude each potential harm with their harm scale
- Estimate likelihood of potential harms
- Compare likelihood of potential harms from research with harm comparable activity, if likelihood comparable, risks of research may be acceptable
Reasons IRBs bad at balancing risks and benefits (Williams)
- Bias in favor of approval HHS guidelines
- Composition of IRBs - strong incentive institutional success
- Psychological effect of committee decisions, group polarization
