Medical ethics: four principles, consent, capacity, confidentiality and truth-telling
Medical ethics for FCPS Part 1: the four principles, valid consent, capacity, children, confidentiality, truth-telling and end-of-life care. Includes family requests to hide a diagnosis, Gillick competence, double effect, brainstem death and impaired colleagues.
The four principles
| Principle | Meaning | Example |
|---|---|---|
| Autonomy | Respect a capable person's right to decide for themselves | Accepting a capable patient's refusal of surgery |
| Beneficence | Act in the patient's best interests | Recommending effective treatment |
| Non-maleficence | Avoid harm; weigh risks against benefits | Stopping futile or harmful treatment |
| Justice | Fair treatment and fair distribution of limited resources | Triage by clinical need; no discrimination |
- Justice in practice means treating similar cases alike and allocating care by need, not by wealth, status or connections. Equity (fairness according to need) differs from equality (identical shares for all).
- Supporting duties: veracity (truthfulness), fidelity (keeping promises), confidentiality, respect for dignity, and probity (honesty in all professional dealings).
- Paternalism (overriding a capable person "for their own good") conflicts with autonomy.
- Ethical theories: duty-based (deontological) ethics judges the act itself; consequentialism (utilitarianism) judges outcomes, aiming at the greatest good for the greatest number; virtue ethics asks what a good doctor would do.
Doctrine of double effect
- An act with a good intended effect and a foreseen but unintended harmful effect is acceptable if the act itself is not wrong, the harm is not the means to the good, and the good outweighs the harm (proportionality).
- Example: increasing morphine to relieve severe pain in a dying patient is acceptable even if it might shorten life, because the intention is relief of suffering.
Valid consent
- Three requirements: capacity, adequate information and voluntariness (free choice without coercion). Consent is a continuing process and may be withdrawn at any time.
- Information: diagnosis, nature and purpose of the procedure, material risks (those a reasonable person in the patient's position would want to know, including rare serious ones), benefits, alternatives including doing nothing, and who will do it.
- Ideally the operator takes consent, or a colleague trained in the procedure. A signed form only records the discussion; it is not itself consent. Consent can be written, verbal or implied (offering an arm for blood).
- Emergency: if the patient lacks capacity and treatment cannot wait, give treatment that is immediately necessary in their best interests (doctrine of necessity).
- A valid and applicable advance refusal made while capable must be respected. A capable adult Jehovah's Witness may refuse blood even if death results; for a child, life-saving transfusion is given in the child's best interests, with legal authority sought where time allows.
Capacity
- Presume capacity. It is decision-specific and time-specific.
- A person has capacity if they can understand the relevant information, retain it long enough, use or weigh it, and communicate a decision.
- An unwise decision is not proof of incapacity. Mental illness, old age or disorientation do not by themselves remove capacity, but they prompt formal assessment.
- Help the person decide (interpreter, simple language, better timing, treat reversible confusion).
- If capacity is lacking: act in best interests, considering the person's past and present wishes, consulting family and carers, choosing the least restrictive option, and waiting if capacity may return and delay is safe.
- A disoriented elderly patient with acute appendicitis who refuses surgery: assess capacity first. If delirium removes capacity and surgery is urgent, proceed in his best interests after involving his wife and documenting the assessment; if he has capacity, his refusal stands.
Children and young people
- Parents consent for young children, but involve the child as far as possible.
- Gillick competence: a young person under 16 can consent if they have enough maturity and understanding of the proposed treatment.
- Fraser guidelines for contraception without parental knowledge: she understands the advice; cannot be persuaded to involve parents; is likely to have sex anyway; her health would suffer without it; it is in her best interests. So a 15-year-old who understands the risks and benefits can receive contraception after the doctor assesses her maturity, while encouraging parental involvement and checking for exploitation.
- Refusal of life-saving treatment by a minor may be overridden by parents or the courts. Local law (age of majority 18 in Pakistan) and hospital policy apply.
Truth-telling and family requests
- A capable patient is entitled to information about their own condition. If a relative asks you not to tell the patient:
- Explore the family's concerns (often fear of causing distress) and explain your duty to the patient.
- Ask the patient how much they want to know and who they want involved; some prefer not to know, and that wish is respected.
- If the patient asks directly, tell him honestly and sensitively. Deceiving a capable patient breaches autonomy and trust.
- Withholding information is justified only if disclosure would cause serious harm (not merely upset), which is rare.
Confidentiality
- The duty continues after death. Sharing with the direct care team is acceptable on implied consent; audit and research need anonymised data or consent.
| Ground for disclosure | Example |
|---|---|
| Consent | Patient agrees to a report to an employer or insurer |
| Required by law | Notifiable diseases, court order, statutory reporting |
| Public interest (serious harm to others) | Driver or pilot with uncontrolled epilepsy who keeps working; credible threat of violence; serious crime |
| Safeguarding | Suspected abuse of a child or vulnerable adult |
- Disclose only the minimum necessary to the appropriate authority, tell the patient first where safe, and record the reasons.
- Epileptic pilot or driver asking for secrecy: explain the danger and advise him to stop and inform the licensing or aviation authority. If he refuses and continues, the doctor may disclose to that authority, after telling him.
- HIV and partner notification: encourage the patient to tell partners; disclosure to a partner at serious risk can be justified if the patient refuses.
- A psychiatrist who does not share a patient's details with relatives without consent is upholding confidentiality.
End of life and brainstem death
- Euthanasia and assisted suicide are illegal in Pakistan and the UK. Withholding and withdrawing futile treatment are ethically equivalent. DNACPR is a clinical decision discussed with the patient and family.
- Brainstem death (before organ donation) requires preconditions (deep apnoeic coma of known irreversible cause, with drugs, hypothermia and metabolic or endocrine causes excluded), then testing by two experienced doctors on two occasions:
| Test | Expected result |
|---|---|
| Pupils | Fixed, not reactive to light |
| Corneal reflex | Absent |
| Vestibulo-ocular (caloric) | No eye movement |
| Cranial motor response to pain | Absent |
| Gag and cough | Absent |
| Apnoea test | No breathing despite raised PaCO2 (at least 6.0 kPa, pH below 7.40) |
- Spinal reflexes may persist and do not exclude brainstem death.
Probity and professional conduct
- Medical certificates and reports must be true: refuse to write a sick note for days the patient was not ill.
- Impaired or unsafe colleague (for example operating while smelling of alcohol): patient safety comes first. Act promptly through proper channels, speaking to the clinical lead or medical director, and to the regulator (PMDC or GMC) if needed; do not ignore it or gossip.
- Duty of candour after errors; no relationships with patients; declare conflicts of interest; careful use of social media.
- Negligence needs duty of care, breach, causation and harm. The Bolam test asks whether a responsible body of medical opinion would support the practice; Bolitho adds that the opinion must be logical.
Research ethics
- Nuremberg Code (voluntary consent), Declaration of Helsinki, Belmont Report (respect for persons, beneficence, justice).
- Ethics committee approval, informed consent with the right to withdraw, confidentiality, equipoise, protection of vulnerable groups. Misconduct: fabrication, falsification, plagiarism.
Remember Valid consent needs capacity, information and free choice; an unwise decision is still the patient's decision.
Exam trap Family members cannot veto what a capable patient is told: explore their worry, then ask the patient what he wants to know.
Exam trap Breach confidentiality only for consent, law or serious risk to others, and disclose the minimum.
How FCPS asks about this
- Requirements of valid consent: capacity, adequate information and voluntariness.
- Brother asks you to hide cancer; capable patient asks what is wrong: tell him honestly and sensitively.
- 15-year-old wants contraception and understands: assess maturity (Gillick, Fraser); she can consent.
- Epileptic pilot asks for secrecy: advise him to inform the authority; disclose if he refuses, telling him first.
- Morphine that may hasten death in terminal pain: doctrine of double effect; foreseen harm accepted if proportionate.
- Brainstem death: absent brainstem reflexes and a positive apnoea test, with reversible causes excluded.
- Colleague operating under the influence of alcohol: raise it through proper channels.
Test yourself on this topic
5 of the 26 questions in our bank on this topic. Choose an answer to see why every option is right or wrong.
A bus driver with uncontrolled epilepsy refuses to stop driving or to inform the licensing authority despite repeated advice. What should the doctor do?
Answer: Tell him you will inform the authority, then do so
Confidentiality is not absolute. It may be broken in the public interest when there is a serious risk of harm to others, such as a driver with uncontrolled seizures. The doctor should first explain the risk and encourage the patient to stop driving and inform the authority himself. If he refuses, the doctor should tell him that the authority will be informed, disclose only the minimum necessary information to the appropriate body, and record the reasons. Disclosing widely to employers or family is not justified.
Public interest disclosure
- Confidentiality is not absolute
- Breach when serious risk to others
- First persuade; then tell him you will disclose
- Disclose minimum, to the right body, and record
Remember Persuade, warn, then disclose the minimum.
Exam trap Disclosure goes to the authority that needs it, not to everyone.
Why the other options are wrong
- Keep it confidential in all circumstances Confidentiality can be breached when others are at serious risk.
- Inform his employer and family without telling him Disclosure should go to the appropriate authority, not widely.
- Report him to the police immediately The licensing authority, not the police, is the appropriate body.
- Stop treating him Abandoning the patient is not appropriate.
A house officer posts a photo of an interesting X-ray with the patient's name visible on a WhatsApp group. What is the main problem?
Answer: Breach of confidentiality
Sharing identifiable patient information (name, MR number, face, unique features) without consent breaches confidentiality, even among colleagues. Images for teaching must be anonymised and consented, and shared only through approved channels.
Confidentiality online
- No identifiers without consent
- Anonymise teaching images
- Use approved channels
Remember If they could be recognised, don't post it.
Why the other options are wrong
- None, if the group is doctors Still a breach.
- Only a copyright issue Confidentiality is the issue.
- Acceptable for teaching Must be anonymised and consented.
- Only if the patient complains The breach exists regardless.
A resident copies paragraphs from a published paper into his thesis without citation. What is this?
Answer: Plagiarism
Research misconduct includes fabrication (inventing data), falsification (manipulating data or results) and plagiarism (using others' words or ideas without credit). All are serious professional breaches; CPSP and the HEC use similarity checks for dissertations.
Research misconduct
- Fabrication: invented data
- Falsification: altered data
- Plagiarism: uncredited copying
Remember FFP: fabrication, falsification, plagiarism.
Why the other options are wrong
- Fabrication Inventing data.
- Falsification Altering data.
- Acceptable paraphrasing Copying without citation is not acceptable.
- Conflict of interest Financial or personal competing interest.
One ICU bed is free, and it is given to the patient most likely to benefit rather than the one with more influence. Which ethical principle is being applied?
Answer: Justice
Justice concerns fair distribution of limited health resources, treating like cases alike and allocating by need and benefit rather than wealth or status. Autonomy is respecting a competent person's choices, beneficence acting in the patient's best interest, and non-maleficence avoiding harm. Veracity is telling the truth.
Four principles
- Autonomy: respect choices
- Beneficence: do good
- Non-maleficence: do no harm
- Justice: fair allocation
Remember Sharing scarce care fairly is justice.
Exam trap Beneficence is about one patient's good; justice is about fairness between patients.
Why the other options are wrong
- Autonomy Respect for the patient's own choices.
- Beneficence Doing good for an individual patient.
- Non-maleficence Avoiding harm.
- Veracity Truth-telling.
A 45-year-old man has a single clinic blood pressure of 152/96 mmHg. He has no symptoms or organ damage. What should be done before diagnosing hypertension?
Answer: Confirm with ambulatory or repeated readings
Blood pressure varies and is often raised in the clinic (white coat effect). Hypertension is confirmed by repeated readings on separate occasions, or preferably by ambulatory or home monitoring, before starting long-term drugs. Exceptions are very high readings (for example 180/120 mmHg or above) or signs of organ damage, which need prompt treatment. Measurement should use a correct cuff size, with the patient seated and rested.
Diagnosing hypertension
- Confirm with ABPM / home readings
- Or repeated clinic readings on separate days
- Exclude white coat effect
- Treat at once if very high or organ damage
Remember One high reading is not hypertension.
Exam trap Very high pressure with organ damage is the exception that needs treatment straight away.
Why the other options are wrong
- Start two drugs immediately Two drugs at once are not needed at this level without confirmation.
- Diagnose hypertension from this reading One reading is not enough for a lifelong diagnosis.
- Refer urgently to cardiology Urgent referral is not needed without very high readings or damage.
- Order an echocardiogram first Echocardiography is not the first step.
