Medical Ethics: A Comprehensive Overview

1. Historical Foundations

• The Essentials of Forensic Medicine and Toxicology, 36th edition, block 1

2. The Four Principles (Beauchamp and Childress)

1. Autonomy

• Informed consent - the process of ensuring a patient understands and freely agrees to treatment
• Confidentiality - protecting patient information
• Truth-telling - honesty in disclosing diagnoses and prognoses

"Every human being of adult years and sound mind has a right to determine what shall be done with his own body; and a surgeon who performs an operation without his patient's consent, commits an assault." - Justice Cardozo

• Scott-Brown's Otorhinolaryngology, block 4

• A persistent sense of self with personal values
• Sufficient understanding of available choices
• Ability to reflect on options and communicate a decision
• Adequate information (what would materially affect the patient's choice)

2. Beneficence

3. Non-Maleficence

• Risk-benefit analysis before procedures
• Medical futility decisions (withholding non-beneficial interventions)

4. Justice

• Distributive justice: equitable allocation of scarce resources
• Rights-based justice: respect for patient legal rights
• Procedural justice: fair processes in healthcare decisions

"The four principles of medical ethics that command wide consensus... provide an acceptable framework, although close scrutiny of many difficult dilemmas highlights limitations in these principles and apparent conflicts between them." - Emery's Elements of Medical Genetics and Genomics

3. Ethical Frameworks (Beyond Principlism)

4. Informed Consent

1. Disclosure - The clinician provides sufficient information (diagnosis, proposed treatment, risks, benefits, alternatives)
2. Capacity - The patient has decision-making capacity (ability to understand, reason, communicate a stable choice)
3. Voluntariness - The decision is made free from coercion

"The doctrine of informed consent operationalizes the duty to respect autonomy; it ensures that the patient is capable..." - Kaplan & Sadock's Comprehensive Textbook of Psychiatry, block 62

• Patients who lack capacity: Decision-making passes to a surrogate (usually next of kin or legal guardian), guided by advance directives or substituted judgment ("what would this patient have wanted?")
• Emergencies: Implied consent when a patient cannot consent and delay would cause harm
• Minors: Parental consent required; however, mature minors may give their own consent in many jurisdictions
• Refusal of treatment: A competent adult may refuse any treatment, including life-sustaining treatment - this must be respected

5. Confidentiality

• Public health duties: Notifiable/communicable diseases must be reported to health authorities
• Risk of serious harm to third parties: e.g., a patient with homicidal intent (Tarasoff principle)
• Legal requirements: Court orders, statutory duties
• Best interests: When a patient lacks capacity and disclosure serves their welfare

6. End-of-Life Ethics

Advance Directives

• Living will: Specifies which treatments to accept or refuse
• Do Not Resuscitate (DNR) orders: Instruction to withhold CPR
• Durable Power of Attorney for Healthcare: Names a surrogate decision-maker

Futility and Withholding Treatment

Euthanasia and Assisted Dying

7. Research Ethics

8. Special Ethical Domains

Confidentiality vs. Disclosure (the Tarasoff dilemma)

Genetics and Genomics Ethics

Resource Allocation (Justice)

Professionalism

9. Common Ethical Dilemmas and How to Approach Them

1. Gather facts - clinical details, patient values, social context
2. Identify the ethical conflict - which principles are in tension?
3. Assess decision-making capacity - is the patient competent?
4. Consult relevant parties - patient, family, team, ethics committee
5. Consider the legal framework - advance directives, relevant statutes
6. Make a reasoned judgment - document reasoning clearly
7. Review and learn - debrief after difficult cases

Key Declarations and Codes at a Glance

Medical Code of Ethics for MBBS Students

1. Historical Evolution of Medical Ethics Oaths

• The Essentials of Forensic Medicine and Toxicology, 36th edition

2. The Four Core Principles of Medical Ethics

🔵 1. Autonomy

• Respect for the patient's right to make their own decisions
• Requires informed consent: disclosure + understanding + voluntary choice
• Covers confidentiality, truth-telling, and the right to refuse treatment
• Decisional capacity must be assessed - if lacking, a surrogate decides

🟢 2. Beneficence

• Act in the patient's best interest and actively do good
• Promote health, prevent disease, relieve suffering
• Underpins clinical duty of care

🔴 3. Non-Maleficence

• Primum non nocere - "first, do no harm"
• Every intervention carries risk; harm of action must be weighed against harm of inaction
• Basis for medical futility decisions and risk-benefit analysis

🟡 4. Justice

• Fairness in treatment and resource distribution
• Includes distributive justice (fair allocation of resources), patient rights, and non-discrimination
• No patient may be denied care on grounds of race, religion, gender, nationality, or social status

3. The Hippocratic Oath (Full Text)

"I will prescribe regimen for the good of my patients according to my ability and my judgment and never do harm to anyone. To please no one will I prescribe a deadly drug, nor give advice which may cause his death... In every house where I come I will enter only for the good of my patients, keeping myself far from all intentional ill-doing... All that may come to my knowledge in the exercise of my profession... I will keep secret and will never reveal. If I keep this oath faithfully, may I enjoy my life and practice my art, respected by all men and in all times."

• P.C. Dikshit Textbook of Forensic Medicine and Toxicology

4. The Declaration of Geneva (1948, Updated 2017)

"AS A MEMBER OF THE MEDICAL PROFESSION:

1. I SOLEMNLY PLEDGE to dedicate my life to the service of humanity
2. THE HEALTH AND WELL-BEING OF MY PATIENT will be my first consideration
3. I WILL RESPECT the autonomy and dignity of my patient
4. I WILL MAINTAIN the utmost respect for human life
5. I WILL NOT PERMIT considerations of age, disease or disability, creed, ethnic origin, gender, nationality, political affiliation, race, sexual orientation, or social standing to intervene between my duty and my patient
6. I WILL RESPECT the secrets that are confided in me, even after the patient has died
7. I WILL PRACTISE my profession with conscience and dignity and in accordance with good medical practice
8. I WILL FOSTER the honour and noble traditions of the medical profession
9. I WILL GIVE to my teachers, colleagues, and students the respect and gratitude that is their due
10. I WILL SHARE my medical knowledge for the benefit of the patient and the advancement of healthcare
11. I WILL ATTEND TO my own health, well-being, and abilities in order to provide care of the highest standard
12. I WILL NOT USE my medical knowledge to violate human rights and civil liberties, even under threat
13. I MAKE THESE PROMISES solemnly, freely, and upon my honour."**

5. Professional Misconduct - What MBBS Students Must Avoid

• P.C. Dikshit Textbook of Forensic Medicine and Toxicology

6. IMC Regulations 2002 - Key Salient Points (Now Under NMC)

1. Doctors may choose their patients but must not refuse emergency care
2. Refer only when absolutely necessary; avoid unnecessary investigations
3. Once a case is accepted, the patient must not be abandoned without notice
4. Fees and charges must be displayed clearly
5. No endorsement of medications or equipment for financial gain
6. Prescribe drugs by generic name as far as possible
7. No sex determination tests for feticide
8. Patients must not be subjected to trials except under ICMR guidelines
9. Maintain patient records for a minimum of 3 years for inpatients

7. Key WMA Declarations Every MBBS Student Should Know

• The Essentials of Forensic Medicine and Toxicology, 36th edition

8. Informed Consent - A Core Duty

• Emergencies - implied consent applies when delay would be harmful
• Minors - parental/guardian consent required; mature minors may consent in some jurisdictions
• Unconscious patients - surrogate/next-of-kin decides; advance directives are honored
• Refusal of treatment - a competent adult has the absolute right to refuse, even life-saving treatment

9. Quick Memory Aid for MBBS Exams

B - Beneficence       → Do Good
N - Non-maleficence   → Do No Harm
A - Autonomy          → Respect Patient's Choice
J - Justice           → Be Fair to All

"BNAJ" or remember as the "4 pillars" of bioethics - every clinical decision should be tested against all four.
