Ethics, consent & medicolegal

Overview and definition

The ethics, consent and medicolegal framework defines the moral and legal basis of the doctor–patient relationship, and the anaesthetist works at its sharpest edge. We render patients unconscious and helpless, administer drugs that can kill in seconds, place needles beside the spinal cord, and make rapid life-and-death decisions in emergencies — and we do much of this out of sight of the patient and their family. The patient's trust, the consent they gave before induction, the documentation we leave behind, and our honesty when things go wrong are the entire moral and legal scaffolding on which the specialty rests. [1]

The analytic foundation is principlism — the four-principle framework of Beauchamp and Childress (autonomy, beneficence, non-maleficence and justice) — which provides a shared vocabulary for reasoning through the conflicts that recur in anaesthetic practice: the competent adult who refuses life-saving blood; the child of Jehovah's Witness parents; the unconscious emergency patient; the patient who lacks capacity; the disclosure of an intraoperative error.[1]

The legal foundation, in the common-law jurisdictions most relevant to ANZCA, FRCA and ABA candidates, is built from a small number of landmark cases and statutes: Bolam v Friern Hospital Management Committee (1957), which set the standard of care by reference to a responsible body of medical opinion; Bolitho v City and Hackney Health Authority (1997), which required that body of opinion to be logically defensible; Gillick v West Norfolk and Wisbech AHA (1985), which established the competent minor's right to consent; the Mental Capacity Act 2005 (England and Wales), which codified the assessment of capacity and best-interests decision-making; and Montgomery v Lanarkshire Health Board (2015), which replaced the Bolam standard for the disclosure of risk with a patient-centred test of materiality. The medicolegal implications of these guidelines are increasingly examined in the anaesthesia literature.[11]

The four ethical principles (Beauchamp and Childress)

Principlism is the common analytic framework used across medical ethics and the one expected in anaesthesia vivas and SAQs. It posits four prima facie principles — each binding unless it conflicts with another, in which case the clinician must balance them in the specific context.[1]

• Autonomy is the respect for the patient's right to self-determination. The competent adult's informed choice governs: they may consent to or refuse any treatment, and paternalism (the historical "doctor knows best") is no longer defensible. Autonomy underwrites the entire doctrine of informed consent and the absolute right to refuse.
• Beneficence is the positive duty to act in the patient's best interests — to relieve pain, to correct physiology, to cure where possible. It is the principle that drives the anaesthetic plan, the choice of technique, and the perioperative optimisation.
• Non-maleficence (primum non nocere) is the negative duty to avoid harm. Every anaesthetic intervention carries risk, and non-maleficence is the weighing of that risk against the benefit — the reason we disclose material risks and the reason we use minimum effective doses, monitors and checks.
• Justice is the fair distribution of benefits, burdens and scarce resources. At the bedside it governs equitable access to theatre time, intensive care beds and donor organs; at the societal level it governs triage, resource allocation and the regulatory environment. [1]

The principles are not a hierarchy. They conflict routinely, and the ethical work is the balancing. The classic anaesthetic conflicts: [1]

[1]

Informed consent

Valid informed consent is a process of communication, not a signature on a form. The signed consent form is the documentation of that process, not the consent itself. The elements that make consent valid are capacity, disclosure, understanding, voluntariness, and the consent itself.[9]

[1]

• Capacity is decision-specific and time-specific — a patient may have capacity to consent to an elective hernia repair but lack capacity to make a complex decision about high-risk cardiac surgery, and capacity may be lost (and recovered) with acute illness, sedation, pain, infection or dementia. Capacity is PRESUMED in the adult; it is only formally assessed (under the Mental Capacity Act in the UK, or its equivalents) when doubt arises.
• Disclosure of risk was transformed by Montgomery v Lanarkshire Health Board (2015). Before Montgomery, the standard for risk disclosure in the UK was itself set by the Bolam test — a doctor had to disclose what a responsible body of doctors would disclose (the Sidaway 1985 application of Bolam). Montgomery replaced this with a patient-centred test: a clinician must disclose any material risk — one to which a reasonable person in the patient's position would attach significance, taking into account both the nature of the risk (its severity and likelihood) and the characteristics of the individual patient. Materiality is judged from the patient's perspective, not the doctor's.
• Understanding is the patient's actual comprehension, tested by asking the patient to recount the plan and the risks in their own words — the "teach-back" method. Disclosure without understanding is not informed consent.
• Voluntariness requires freedom from coercion — by family, by clinicians, by institutional pressure. The patient must be free to refuse.
• Consent is the agreement to the specific intervention proposed, given by a patient with capacity, after disclosure and with understanding, voluntarily. Consent may be withdrawn at any time, including immediately before induction. [1]

[1]

The anaesthetic consent — specific risks and the ASA classification

The anaesthetic consent is a specific clinical encounter with its own characteristic risks and its own structured record. The Royal College of Anaesthetists, ANZCA and the ABA publish risk-disclosure guidance; the principle throughout is that disclosure should cover the risks a reasonable patient would want to know, weighted toward the common and the serious.[10][11]

[1]

The specific anaesthetic risks that must be discussed at consent, with the order of magnitude of their frequency: [1]

• Dental damage (chipped or avulsed teeth, lip laceration) — common, on the order of 1 in 100 to 1 in 1,000 intubations; the upper incisors are most often affected. Pre-existing dental work and the difficult airway increase the risk. Document the pre-induction dental inspection.
• Aspiration of gastric contents — rare in the elective fasted patient (around 1 in 2,000 to 1 in 4,000) but more common in the emergency, full-stomach, obstetric, and bowel-obstruction patient; the consequences (pneumonitis, ARDS) are serious. Discuss the rapid-sequence induction and the fasting guidance.
• Awareness under general anaesthesia (explicit recall of intraoperative events) — the AAGBI and NAP5 figure of around 1 in 19,000 in prospective reports rising to 1 in 4,000 in some high-risk groups (cardiac, caesarean, total intravenous anaesthesia without end-tidal monitoring, paralysed patients). Distressing awareness must be discussed when the risk is elevated, and an awareness plan documented.
• Post-operative nausea and vomiting (PONV) — the most common patient-reported morbidity (around 30% without prophylaxis), and a leading source of patient dissatisfaction. Discuss the risk and the prophylaxis strategy (Apfel score, multimodal antiemetic regimen).
• Nerve injury from regional anaesthesia — around 1 in 4,000 to 1 in 13,000 neuraxial and peripheral blocks; most resolve but some persist. Disclose for any regional technique.
• Death and brain injury — rare (on the order of 1 in 100,000 directly attributable to anaesthesia in the elective ASA 1 to 2 patient; higher in the emergency and ASA 3 to 5 patient). The patient must be told that anaesthesia carries a small but non-zero risk of catastrophic outcome. [1]

[1]

The ASA Physical Status Classification

The ASA Physical Status Classification (American Society of Anesthesiologists), assigned at the pre-anaesthesia consultation, summarises the patient's preoperative functional status and is the most widely used risk-stratification tool in anaesthesia. It is NOT a surgical or anaesthetic risk score, and it does not incorporate age, airway difficulty or surgical complexity — those are documented separately. The classification has been tracked across changing case-mix, with outcomes worsening as ASA class rises.[12]

[1]

The consent form

The consent form is the legal record that consent was sought. In the UK the PR form (procedure-specific) or the standard Consent Form 1 is used; in ANZ the institutional consent form; in the USA the institutional informed-consent document. The form documents the procedure, the material risks discussed, the alternatives (including no treatment), the clinician who took consent, and the patient's signature. Increasingly, shared decision-making is recognised as the gold standard for the consent conversation — the clinician brings the evidence, the patient brings their values and preferences, and the decision is reached collaboratively.[9]

Capacity assessment — the Mental Capacity Act 2005

When there is doubt about a patient's ability to consent, formal capacity assessment is required. In England and Wales this is governed by the Mental Capacity Act 2005; analogous statutes and common-law principles apply across Australasia (the Guardianship and Administration Acts and the common law), the USA, and most common-law jurisdictions. The Act's five guiding principles are exam-classic. [1]

[1]

The two-stage test of capacity

The Act's test for incapacity has two stages — a diagnostic stage and a functional stage. Both must be satisfied for a finding of incapacity.[1]

• Stage 1 — Diagnostic (the impairment of mind or brain). Is there an impairment of, or disturbance in the functioning of, the mind or brain? Acute confusional state, dementia, learning disability, psychosis, intoxication, sedation, head injury, the post-ictal state — any of these satisfies the diagnostic stage. If there is no such impairment, the patient has capacity and the test stops.
• Stage 2 — Functional (the inability to decide). If the diagnostic stage is satisfied, can the patient (a) understand the information relevant to the decision, (b) retain it long enough to decide, (c) use or weigh that information as part of the decision-making process, and (d) communicate the decision (by any means)? Failure of any one of the four functional limbs — in the context of an impairment of mind or brain — establishes incapacity for that specific decision at that time. [1]

The two cardinal features of the test: capacity is decision-specific (the patient may have capacity for a simple decision but not for a complex one) and time-specific (capacity lost through delirium may be recovered as the patient improves). Capacity should be re-assessed whenever the clinical state changes. [1]

Best-interests decision-making

When a patient lacks capacity, decisions are made in their best interests under section 4 of the Act. The decision-maker is the clinician providing the treatment (not, by default, the family). The best-interests checklist requires the decision-maker to: [1]

• consider whether the patient is likely to regain capacity and whether the decision can wait;
• so far as reasonably ascertainable, consider the patient's past and present wishes and feelings, any advance statement, and the beliefs and values that would be likely to influence the decision;
• consult, where practicable and appropriate, anyone named by the patient as someone to consult, anyone engaged in caring for the patient, any holder of a lasting power of attorney, and any deputy;
• avoid discrimination — the decision cannot be based merely on the patient's age, appearance or condition;
• apply the least restrictive option principle (the fifth guiding principle). [1]

For the unconscious emergency patient (trauma, cardiac arrest, the obtunded overdose), emergency treatment proceeds under the doctrine of necessity (implied consent — what the reasonable person would consent to) and in the patient's best interests. Restraint, sedation and deprivation of liberty have specific safeguards under the Act (sections 5 and 6, and the Deprivation of Liberty Safeguards / Liberty Protection Safeguards). [1]

Refusal of treatment — the competent adult's absolute right

A cornerstone of common-law autonomy, repeatedly affirmed, is that a competent adult has an absolute right to refuse any medical treatment, including life-saving treatment, for any reason or no reason, even where the refusal appears unwise or irrational. The right is absolute. To treat a competent adult who has refused is battery (the tort of trespass to the person), regardless of whether the treatment was clinically beneficial.[1]

The anaesthetic consequence is direct. The classic scenario is the Jehovah's Witness who, on religious grounds, refuses whole blood, packed red cells, platelets, fresh frozen plasma and (in most cases) pre-deposited autologous blood. The competent adult JW's refusal is binding, and the anaesthetist must respect it and plan a transfusion-free (bloodless) technique:[2][3][8]

[1]

The medico-legal aspects of transfusion-free care have been examined in detail — anaesthetists offering bloodless surgery must work within a structured programme with consent that explicitly documents which blood fractions and cell-salvage circuits the individual JW patient will and will not accept, because there is genuine individual variation in JW doctrine.[3] The recent successful bloodless combined heart–liver transplant in a JW patient shows the achievable extremes of the technique in major surgery.[8]

The Jehovah's Witness obstetric patient is a particularly high-stakes variant: the haemorrhage risk of the peripartum period, the rapid physiology, and the fact that there are two patients — mother and fetus. The literature review of the obstetric JW patient summarises the antenatal optimisation, the peripartum plan, and the medicolegal approach.[4] An advance refusal (a signed JW card or advance directive refusing blood) is binding while the patient has capacity for the refusal it represents, but in an emergency an unconscious patient's earlier clear and specific advance refusal must still be honoured.

[1]

Children and consent — Gillick, Fraser and parental responsibility

Consent for a child involves the interaction of the child's developing autonomy and the parental responsibility to act in the child's best interests. The framework is built on three pillars: parental responsibility, Gillick competence, and the role of the court as the ultimate safeguard of the child's welfare.[1]

Parental responsibility

Parental responsibility is the legal right, duty and authority to make decisions for a child. It is held by the child's mother automatically, by the father if he was married to the mother at the time of birth or acquired it (in the UK by being named on the birth certificate for births after 1 December 2003, by parental responsibility agreement, or by court order), and by adoptive parents, guardians and those with a residence or special guardianship order. A person with parental responsibility can give valid consent for the medical treatment of a child in their best interests. [1]

Gillick competence and the Fraser guidelines

Gillick competence (after the House of Lords decision in Gillick v West Norfolk and Wisbech AHA, 1985) is the principle that a child under 16 who has sufficient understanding and intelligence to understand fully what is proposed may give valid consent to treatment independently of their parents. The test is functionally the same as the test of adult capacity — the ability to understand, retain, use and weigh the information, and to communicate the decision — applied with appropriate care to a child. A Gillick-competent child's consent is sufficient and the parent's consent is not additionally required (though involving the family is good practice where the child agrees). [1]

The Fraser guidelines are a narrow subset of Gillick competence, named after Lord Fraser, and apply specifically to the provision of contraceptive advice and treatment to a young person under 16. The three Fraser criteria (the young person understands the advice, cannot be persuaded to inform the parents, is likely to continue having sexual intercourse, and that their physical or mental health will suffer without advice or treatment) allow a doctor to provide contraception without parental knowledge or consent. The Fraser guidelines are commonly confused with Gillick competence in the viva — Fraser is contraception-specific; Gillick is the general test of the competent minor. [1]

Children aged 16 and 17 are presumed to have capacity to consent to medical treatment in most jurisdictions (in the UK under the Family Law Reform Act 1969), and are treated for consent purposes much like adults. [1]

Refusal by the child or parent — the court's role

The asymmetry that examiners probe: a competent minor (or a parent) may CONSENT to treatment independently, but a REFUSAL of life-saving treatment by a child or by those with parental responsibility may be overridden by the court in the child's best interests. The court's inherent jurisdiction (wardship; the parens patriae jurisdiction) makes the child's welfare the paramount consideration. This is the legal architecture of the conflicted Jehovah's Witness child scenario discussed below. [1]

The conflicted Jehovah's Witness child

The conflicted JW child is the exam-classic synthesis of autonomy, beneficence, the limits of parental responsibility, and the role of the court. It binds together everything in this topic and is a frequent SAQ, viva and hot-case stimulus.[1]

The structure of the answer: [1]

[1]

The practical management of the conflicted JW child for elective or urgent surgery: [1]

1. Anticipate — identify the JW child at pre-assessment, involve the consultant anaesthetist, the surgeon, the haematology team, the hospital transfusion committee, the JW Hospital Liaison Committee, the ethics committee and (early) the hospital legal team.
2. Clarify — establish exactly which blood products, fractions and cell-salvage circuits the JW parents will and will not accept, in writing.
3. Optimise — maximise the haemoglobin with iron and erythropoietin, plan the bloodless surgical and anaesthetic technique, and time the surgery to minimise bleeding risk.
4. Plan the legal route — for an ELECTIVE case where the parents refuse potentially life-saving blood, obtain a court order (Specific Issue Order) BEFORE surgery authorising transfusion in the event of life-threatening haemorrhage. For an EMERGENCY, proceed under the doctrine of necessity and apply for an emergency court order.
5. Document the entire conversation, the optimisation, the legal opinion, and the agreed thresholds. [1]

Restraint and the anaesthetist

Restraint — the physical or chemical restraint of a patient — raises both ethical and legal issues, particularly in the patient who lacks capacity. Under the Mental Capacity Act 2005 (sections 5 and 6), a clinician may use proportionate and necessary restraint on a patient who lacks capacity, in the patient's best interests, where the clinician reasonably believes it is necessary to prevent harm to the patient. The restraint must be the least restrictive option consistent with the prevention of harm. [1]

The anaesthetist encounters restraint in: the agitated patient who lacks capacity needing an emergency procedure; the patient with delirium or dementia refusing essential care; the paediatric patient requiring restraint for induction (where distraction and pharmacological anxiolysis have largely replaced physical restraint in modern paediatric anaesthesia); and the patient in intensive care needing sedation for treatment they cannot consent to. Deprivation of liberty (more than restraint — a continuous and complete deprivation) requires additional safeguards (the Deprivation of Liberty Safeguards in England and Wales, and analogous jurisdictional equivalents) and authorisation. [1]

Confidentiality, data protection and the Caldicott principles

The patient's information is confidential; the duty to protect it is both an ethical duty (a component of autonomy and trust) and a legal duty (under the common law of confidence, the General Data Protection Regulation and the Data Protection Act 2018 in the UK, the Privacy Act 1988 in Australia, and the Health Information Privacy Code in New Zealand).[5]

The Caldicott principles (first published 1997, updated 2013 and 2020) govern the handling of patient-identifiable information in the NHS and are widely adopted. The eight principles: (1) justify the purpose; (2) use the minimum necessary patient-identifiable information; (3) use the minimum necessary access; (4) respect the duty to confidentiality; (5) understand and comply with the law; (6) understand the duty to share information can be as important as the duty to protect confidentiality; (7) the duty to share information for individual direct care is as important as the duty to protect confidentiality; (8) inform patients and the public about how their information is used. [1]

The duty of confidentiality is not absolute. The recognised exceptions to the duty (when disclosure may be required or justified): [1]

• Consent of the patient to the disclosure.
• Statutory requirement — the law requires disclosure (e.g. notification of certain infectious diseases, gunshot wounds, knife wounds in some jurisdictions, child protection proceedings, court orders).
• Public interest — disclosure is justified to prevent a serious harm to others (the patient who is unfit to drive, the patient who has made a credible threat of serious violence, the patient who poses a risk of serious transmissible infection and is not modifying their behaviour).
• Safeguarding — disclosure to protect a child or vulnerable adult. [1]

The anaesthetist's particular confidentiality hazards: the corridor conversation about a patient within earshot of others; the teaching case discussed with the patient identifiable; the photo on a personal phone; the perioperative handover overheard; and the request for information about a patient from a relative or a third party without the patient's consent. [1]

The duty of candour and open disclosure

The duty of candour is the ethical and, increasingly, the statutory obligation to be open and honest with patients when something has gone wrong. The 2014 NHS contractual statutory duty of candour (regulated by the CQC in England, with analogous duties in the devolved nations and in ANZ under the Australian Open Disclosure Framework and the NZ Health and Disability Commissioner's guidance) requires the healthcare provider to inform the patient (or their representative) as soon as practicable after a notifiable safety incident — an unintended or unexpected incident that results in moderate or severe harm or death — to apologise, to explain what happened, to describe the action taken, and to provide support. Concealment is itself a regulatory offence and, in cases of deliberate concealment, a criminal offence.[5]

The elements of good open disclosure are timely, honest, empathic, apologetic and factual:[5][6]

• Timely — as soon as the patient is clinically able to receive the information; not weeks later.
• Honest — what is known, what is not known, and what is being done to find out.
• Empathic — recognising the patient's and family's experience; the patient and family experience of open disclosure shapes the trust and the litigation risk, and poor disclosure compounds the harm.
• Apolgetic — an apology is not an admission of liability in most jurisdictions and is explicitly protected from being treated as such in some.
• Factual — what happened, the consequences, the actions, the follow-up plan, the lessons learned. [1]

The anaesthetist is also a second victim of an adverse event — the clinician who made or witnessed the error suffers shock, self-doubt, shame and burnout. The duty of candour includes supporting colleagues, the structured debrief, and the institution's responsibility to the staff involved as well as to the patient. [1]

Medicolegal framework — negligence, Bolam, Bolitho and the expert witness

The tort of negligence is the most common legal action arising from anaesthetic practice. To succeed, the claimant (the patient) must establish four elements on the balance of probabilities:[11]

[1]

The standard of care — Bolam and Bolitho

The standard of care in negligence was, for decades, set by Bolam v Friern Hospital Management Committee (1957) — the Bolam test. McNair J directed the jury that a doctor is not negligent if they act in accordance with a practice accepted as proper by a responsible body of medical men skilled in that particular art. The test was famously permissive — it was enough to find ONE responsible body of opinion supporting the doctor's practice, even if other bodies of opinion disagreed. Bolam was applied not just to treatment but, until Montgomery, to the disclosure of risk (the Sidaway 1985 application). [1]

The Bolam test was refined by Bolitho v City and Hackney Health Authority (1997). Lord Browne-Wilkinson held that the court is not bound to accept a doctor's evidence as to standard practice merely because some experts assert it — the court must be satisfied that the body of opinion is logically defensible: the experts must have reached a defensible conclusion, and the court is entitled to reject a body of opinion that is not capable of withstanding logical analysis. Bolitho thus returned to the judiciary the ultimate authority over the standard of care — the judge, not the expert, decides what is negligent. [1]

The trajectory of the law — from Bolam (the doctor's peers decide) through Bolitho (the court must be satisfied the peers are logical) to Montgomery (the patient's perspective governs disclosure) — is the central story of medical negligence in the UK and is the standard viva outline. [1]

The expert witness

In negligence cases the standard of care is established through the evidence of expert witnesses — senior clinicians in the same specialty instructed by the parties (or, increasingly, single joint experts). The expert's duty is to the court, not to the instructing party (the Civil Procedure Rules in England and Wales codify this). The expert explains the standard of care, whether the defendant met it, and whether the breach caused the harm — but, after Bolitho, the court retains the ultimate decision. The anaesthetist as expert witness must be objective, must confine opinion to their area of expertise, and must distinguish fact from opinion. [1]

Causation and the "but for" test

Causation is established on the "but for" test: but for the breach, would the harm have occurred? If the harm would have occurred anyway (e.g. the same nerve injury would have arisen from a recognised complication even with perfect technique), the breach did not cause the harm and the claim fails on causation. Causation is often the most contested element in anaesthetic negligence — particularly in awareness, nerve injury and death cases, where the defendant often concedes a breach (a poor consent, an inadequate record) but denies that the breach caused the specific harm. [1]

The coroner and anaesthetic deaths

Anaesthetic deaths are reportable to the coroner (or the procurator fiscal in Scotland, the coroner in ANZ jurisdictions, and the medical examiner in the USA) where the death is sudden, unexpected, occurs within 24 hours of an anaesthetic, is related to a surgical or anaesthetic procedure, or is otherwise of concern. The anaesthetist's role in the coronial process: to report the death (via the institution's governance team), to provide a written statement of the events, to attend the inquest if called, and to give honest, factual evidence. The coroner's court establishes the who, when, where and how of the death (the medical cause and the circumstances), not criminal or civil liability. Anaesthetic deaths frequently trigger a coronial inquest and may be referred onward to a criminal investigation or to the regulator. [1]

Critical incident reporting

Critical-incident reporting is the structured capture and analysis of adverse events and near-misses for organisational learning. The reporting systems (DATIX, RL Datix, CIMS in ANZ, the Anaesthetic Incident Reporting System, and the global WHO Patient Safety reporting) feed into governance, the root-cause analysis process, and the published literature. The Royal College of Anaesthetists' NAP (National Audit Projects) — most famously NAP5 on accidental awareness — are landmark syntheses of the anaesthetic critical-incident data. The maximising of learning from patient safety incidents, particularly in the emergency-care setting where reporting has historically been weakest, is itself the subject of published improvement work.[6]

The anaesthetist's duty is to report, to participate honestly in the investigation, and to translate the lessons into practice. Concealment is both a regulatory offence and a patient-safety failure — the unreported incident recurs in another patient. [1]

Professional regulation — GMC, ANZCA, MBA, AHPRA

The anaesthetist is a regulated professional on three layers: the medical regulator (registration, conduct, fitness to practise), the professional college (training, examinations, continuing professional development, professional standards), and the employer (clinical governance, appraisal, revalidation). [1]

• General Medical Council (GMC) (UK) — the statutory regulator of all doctors in the UK; sets Good Medical Practice, holds the medical register, and adjudicates fitness-to-practise concerns. Revalidation (every five years, based on annual appraisal) is the mechanism by which GMC licence to practise is maintained. The Australian equivalents are the Medical Board of Australia (MBA) and AHPRA (the Australian Health Practitioner Regulation Agency); the New Zealand equivalent is the Medical Council of New Zealand. The FRCA is awarded by the Royal College of Anaesthetists (RCoA).
• Australian and New Zealand College of Anaesthetists (ANZCA) — the specialist college for anaesthesia and pain medicine in ANZ, setting the training curriculum (the Primary and Final examinations), the continuing professional development (CPD) program, and the professional documents (the PS series) that codify standards of anaesthetic practice. ANZCA fellows must maintain CPD and comply with the ANZCA professional documents.
• Other regulators — the General Pharmaceutical Council, the Nursing and Midwifery Council, and the Care Quality Commission (CQC) regulate the wider team and the institutions. [1]

The impaired anaesthetist (the substance-use, the physical or mental health impairment) is managed through dedicated health-program pathways (the Practitioner Health Programme in the UK, the doctors' health programs of the AMA and NZMC in ANZ) — the principle is that early, confidential, supportive referral serves both the impaired doctor and patient safety better than late disciplinary action. [1]

End-of-life decisions, advance directives and DNACPR

End-of-life decisions bring the four principles into sharp conflict — autonomy (the patient's right to refuse), beneficence (the duty to act in their interests), non-maleficence (the duty not to prolong dying), and the question of futility (treatment that cannot achieve its physiological goal or produce a meaningful benefit).[7]

The advance directive (the "living will", the advance decision in England and Wales under the Mental Capacity Act sections 24 to 26) is the patient's prior statement of treatment preferences for a future state of incapacity. An advance decision REFUSING a specific treatment (e.g. no CPR, no ventilation, no blood, no artificial nutrition) is binding if it is valid and applicable — the patient had capacity when they made it, it clearly refers to the treatment now proposed, and there is no reasonable doubt it has been superseded. A Lasting Power of Attorney for Health and Welfare (in England and Wales) appoints a surrogate to make best-interests decisions on the patient's behalf when they lack capacity. [1]

The DNACPR (do-not-attempt-cardiopulmonary-resuscitation) decision balances the likelihood of CPR success (low in advanced disease, in the frail elderly, and in metastatic cancer), the patient's wishes, the quality of life, and the question of futility. The decision must involve the patient (if they have capacity) or those close to them, must be documented, and must be communicated to all who need to know. The Tracey judgment (2014) confirmed that there is a duty to consult the patient or family about a DNACPR decision unless the consultation would cause harm. The anaesthetist encountering a DNACPR patient for elective or emergency surgery must clarify the perioperative resuscitation status — whether the DNACPR is suspended for the perioperative period (a common position, given the reversible intraoperative causes of arrest such as vagal-mediated arrest, anaphylaxis, hypoxia and hypovolaemia) — and document the agreed plan. [1]

Research ethics and conflicts of interest

Clinical research is governed by an additional ethical framework: the Declaration of Helsinki (the World Medical Association's foundational document on human research ethics), the requirement for research ethics committee approval, the requirement for informed consent to participation (with specific protections for vulnerable subjects and those lacking capacity), the principle of equipoise (genuine uncertainty as to which arm of a trial is superior), the registration of trials, and the integrity of publication. Conflicts of interest (financial, intellectual) must be declared and managed. Anaesthesia research and trials operate within this framework. [1]

Documentation — the medicolegal record

The documentation is the legal record and the defence. The anaesthetic record (the preoperative assessment, the consent, the induction, the maintenance, the events, the monitoring, the drugs, the fluid, the emergence, the recovery), the consent form, the operation note, and the incident reports together form the contemporaneous record. The principles: accurate, contemporaneous, legible, signed and dated. The maxim "if it isn't documented, it wasn't done" holds in court. The defensive extremes are both errors — the over-documentation that obscures the record, and the omission that leaves the defence exposed. The accurate, honest, contemporaneous record is both the patient's record and the clinician's defence.[6]
