Medical ethics Study Guide

📖 Core Concepts Medical Ethics – Applied branch of ethics that examines clinical practice and research. Four Core Values – Respect for autonomy, beneficence, non‑maleficence, and justice; none is ranked above the others. Informed Consent – Process requiring disclosure, comprehension, voluntariness, and competence. Confidentiality / HIPAA – Legal duty to protect patient information; limited exceptions (e.g., gunshot wounds, notifiable diseases). Historical Codes – Nuremberg Code (1947) and Declaration of Helsinki (1964) set foundational research‑ethics standards. Principle of Double Effect – One action can have both a intended beneficial effect and an unintended harmful effect; moral permissibility depends on intent and proportionality. Advance Directives & Capacity – Legal tools (living will, durable power of attorney) guide care when patients lack decision‑making capacity. Justice in Resource Allocation – Fair distribution of scarce resources (e.g., ICU beds, ventilators) especially highlighted during COVID‑19. --- 📌 Must Remember Autonomy = patient’s right to choose/decline after adequate information. Beneficence = act in the patient’s best interests. Non‑maleficence = “first, do no harm.” Justice = equitable access to care and resources. Informed Consent Elements: Disclosure, Comprehension, Voluntariness, Competence. HIPAA Exceptions: mandatory reporting (gunshot wounds, impaired drivers, certain communicable diseases). Nuremberg Code – First research ethics code; emphasizes voluntary consent. Declaration of Helsinki – Expands on consent, risk‑benefit analysis, protection of vulnerable groups. Double Effect Requirements: (1) the act itself is morally good or neutral, (2) the good effect is intended, (3) the bad effect is not the means to the good, (4) the good outweighs the bad. Conflict of Interest (COI) – Financial ties (gifts, speaker fees, self‑referral) can bias prescribing and increase costs; prohibited by professional ethics manuals. --- 🔄 Key Processes Obtaining Informed Consent Assess capacity → Explain nature, purpose, risks, benefits, alternatives → Check understanding → Ensure voluntary decision → Document consent (process, not just signature). Evaluating Decision‑Making Capacity Determine if patient can understand, appreciate, reason, and communicate a choice. If lacking → Apply substituted judgment using advance directives or surrogate decision‑maker. Ethical Triage (Justice in Crisis) Identify scarcity (e.g., ventilators). Apply objective criteria (likelihood of benefit, urgency, life‑years saved). Document decisions; involve ethics committee when possible. IRB / Ethics Committee Review Submit protocol → risk‑benefit analysis → informed‑consent plan → special protections for vulnerable groups → Receive approval before commencing research. Managing COI Disclose all financial relationships → Recuse from decisions where bias may exist → Follow institutional COI policies (e.g., no gifts > modest value). --- 🔍 Key Comparisons Nuremberg Code vs. Declaration of Helsinki Scope: Nuremberg – concise, fundamental principles; Helsinki – extensive, detailed commentary. Research focus: Nuremberg emphasizes voluntary consent; Helsinki adds risk‑benefit analysis and guidance for vulnerable populations. Autonomy vs. Beneficence Autonomy: patient‑driven choice; Beneficence: clinician‑driven best‑interest action. Conflict arises when a competent patient refuses a beneficial treatment. Advance Directive vs. Substituted Judgment Advance Directive: patient’s prior written wishes; Substituted Judgment: surrogate infers what patient would have wanted when no directive exists. --- ⚠️ Common Misunderstandings “Informed consent = signature” – Consent is a process; a signature alone does not guarantee comprehension or voluntariness. “Justice only means equality” – Justice involves fair distribution based on need and benefit, not identical treatment for all. “Physicians can always override patient wishes for beneficence” – Competent patient autonomy supersedes beneficence unless capacity is absent. “HIPAA prevents all information sharing” – Mandatory reporting laws create lawful exceptions. --- 🧠 Mental Models / Intuition “Four‑Quadrant Compass” – Visualize autonomy, beneficence, non‑maleficence, and justice as compass points; ethical decisions require checking each direction. “Risk‑Benefit Scale” – Imagine a balance: if benefit outweighs foreseeable harm and intent is good, the action may be permissible (double effect). “Capacity Ladder” – Ascend from no capacity → limited → full; the higher you climb, the more weight the patient’s own choices carry. --- 🚩 Exceptions & Edge Cases Emergency Exceptions to Consent – When patient is incapacitated and immediate treatment is required to prevent death or serious harm. Confidentiality Limits – Reporting of gunshot wounds, impaired drivers, certain infectious diseases, and court orders. Research on Online Communities – Must still obtain consent or ensure anonymity; IRB review required even for “public” forums. Cultural Practices vs. Patient Rights – Respect cultural beliefs unless they threaten patient safety or violate fundamental rights (e.g., forced treatment). --- 📍 When to Use Which Use Advance Directives → When patient lacks capacity and a written directive exists. Apply Substituted Judgment → No directive, but a known surrogate can infer patient’s prior preferences. Invoke Emergency Consent Exception → Life‑threatening situation, no time for formal consent, and patient is incapacitated. Choose IRB Review vs. Hospital Ethics Committee → IRB for research protocols; Ethics Committee for clinical dilemmas (e.g., end‑of‑life disputes). --- 👀 Patterns to Recognize “Capacity + Conflict” → Whenever a patient’s decision conflicts with clinician’s recommendation, first assess capacity before proceeding. “Scarcity → Justice” → In any resource‑limited scenario (pandemic, organ allocation), look for explicit justice criteria. “COI Red Flags” – Frequent gifts, speaker fees, or self‑referral patterns often signal a conflict that must be disclosed. “Double Effect Language” – Phrases like “intended benefit” vs. “foreseeable harm” signal the principle is in play. --- 🗂️ Exam Traps Distractor: “The physician must always follow the patient’s wishes, even if the patient lacks capacity.” – Wrong; capacity is prerequisite. Distractor: “HIPAA allows physicians to share any health information with family members.” – Wrong; only with patient consent or legal authority. Distractor: “The Nuremberg Code is more detailed than the Helsinki Declaration.” – Inverted; Helsinki is the more detailed document. Distractor: “Beneficence overrides autonomy in all cases.” – Incorrect; autonomy prevails when the patient is competent. Distractor: “Any financial gift from a pharma company is permissible if under \$50.” – Not a safe rule; any gift can create perceived bias and must be disclosed per COI policies. ---
