IRB and regulatory oversight

IRB Fundamentals - The Research Guardians

• Mandate: Protect the rights, safety, and welfare of human research participants, ensuring ethical conduct.
• Core Functions:
  • Assesses risk-benefit ratio.
  • Ensures voluntary, informed consent.
  • Guarantees equitable subject selection.
• Review Levels:
  • Exempt: No-risk research (e.g., de-identified data).
  • Expedited: Not greater than minimal risk (e.g., blood draws, surveys).
  • Full Board: Greater than minimal risk or involves vulnerable populations.

⭐ IRB Composition: Must have at least 5 members, including one scientist, one non-scientist, and one member unaffiliated with the institution.

Ethical Principles - The Guiding Stars

• Beneficence & Non-maleficence: Maximize benefits and minimize harm. Research design must be sound, with risks justified by potential benefits. The guiding principle is primum non nocere (first, do no harm).
• Autonomy: Respect for persons. Individuals must be empowered to make informed, voluntary decisions about participation, free from coercion.
  • This is upheld through the process of informed consent.
  • Vulnerable populations (e.g., children, prisoners, pregnant women) require additional protections.
• Justice: Fair distribution of the burdens and benefits of research. Subject selection must be equitable, not targeting disadvantaged groups.

⭐ For research involving minors, parental permission is required, but the child's assent (affirmative agreement) should also be sought if they are capable (typically age >7).

IRB Review & Consent - The Permission Slip

An Institutional Review Board (IRB) ensures ethical conduct in human research, primarily by safeguarding participant rights and welfare.

• Informed Consent: An ongoing communication process, not just a form.
  • Requires Disclosure (risks, benefits, alternatives), Understanding, Capacity (competence), and Voluntariness.
  • Waiver is possible for minimal risk research.
• Special Populations: Children, prisoners, and pregnant women require additional protections.

⭐ For minors, parental permission is required, but the child's assent (agreement) must also be obtained if they are capable of understanding (typically age >7).

Vulnerable Populations - Handle With Care

• Groups with ↓ autonomy, susceptible to coercion or undue influence, requiring extra IRB protections.
• Key Populations & Safeguards:
  • Children/Minors: Require parental/guardian permission AND child's assent (if age-appropriate, typically >7 years).
  • Pregnant Women & Fetuses: Research must minimize risk and offer potential direct benefit to the woman or fetus.
  • Prisoners: IRB must include a prisoner representative. Avoid coercion; research should be relevant to prisoner health.
  • Decisionally Incapacitated: Require consent from a legally authorized representative (LAR).

⭐ Research on children with > minimal risk and no direct benefit requires approval from both parents/guardians.

High‑Yield Points - ⚡ Biggest Takeaways

• The Institutional Review Board (IRB)'s primary role is to protect the rights and welfare of human research subjects.
• Ethical guidance comes from the Belmont Report: respect for persons (autonomy), beneficence (do no harm), and justice (fairness).
• Informed consent is a mandatory process, not just a form, ensuring participants understand the study's purpose, risks, and benefits.
• Vulnerable populations (e.g., children, prisoners, pregnant women) require stricter protections.
• Research is categorized by risk into exempt, expedited, or full board review.
