Study Notes
Ethics in Biomedical Engineering
- Biomedical engineers develop life-saving technologies (pacemakers, prosthetics, gene editing).
- Ethical decisions impact patient safety, equity, innovation, and public trust.
- Key considerations involve balancing cost, safety, accessibility, and privacy.
Bioengineering Research on Human Subjects
- Ethical dilemmas exist regarding research oversight. Lax rules harm patients; strict rules may delay lifesaving treatments.
Ethical Frameworks for Decision-Making
- Utilitarianism: prioritizes the greatest good for the greatest number of people.
- Deontology: focuses on duties and principles, regardless of outcomes.
Bioethical Principles
- Autonomy: respecting patients' right to make decisions regarding their own care.
- Non-Maleficence: avoiding harm.
- Beneficence: acting in the patient's best interest.
- Justice: ensuring fairness in distributing benefits and risks.
Historical Ethical Cases
Nazi Medical Experiments (WWII)
- Conducted on prisoners without consent.
- Key ethical violations: lacked informed consent, deliberately harmed, and exploited vulnerable populations.
- Led to the development of the Nuremberg Code (1947), establishing guidelines for ethical research (informed consent, minimizing risk).
Thalidomide Tragedy (1950s)
- Sedative caused birth defects in ~10,000-20,000 children due to insufficient safety testing before use.
- Key ethical violations: inadequate testing, poor public disclosure, and weak regulatory oversight.
- Resulted in stricter drug regulations (U.S. Kefauver-Harris Amendment).
Tuskegee Syphilis Study (1932-1972)
- Observed untreated syphilis in African American men without informing them or providing treatment.
- Key ethical violations: deception, lack of consent, racial exploitation, and medical racism.
- Led to the development of the Belmont Report (1979), establishing principles of respect for persons, beneficence, and justice.
Jesse Gelsinger Case (1999)
- Gene therapy trial participant died due to undisclosed risks and conflicts of interest.
- Key ethical violations: lack of full disclosure, and ethical compromise due to financial ties.
- Triggered stricter oversight of gene therapy trials and conflicts of interest.
Informed Consent and Research Oversight
- Informed Consent: participants must fully understand risks and benefits.
- The Common Rule (1991): outlines requirements for informed consent and research oversight, enhancing protections for vulnerable populations (pregnant women, fetuses, prisoners, children).
Key Ethical Considerations in Clinical Research
- Beneficence, Non-Maleficence, Autonomy, Justice are critical principles.
Justification
- Strong reasoning is important when confronting ethical dilemmas with few clear answers.
Lessons Learned
- Informed consent is essential for ethical research.
- Rigorous oversight prevents harm and builds trust.
- Transparency and accountability maintain public confidence.
