About This Page
This is a clinician-written, evidence-based summary aligned to the 2026 MLA Content Map. It is intended for medical students and junior doctors preparing for the UKMLA. Always cross-reference with NICE guidance, local protocols, and clinical judgement.
Key points
- Withdrawal/withholding treatment: legally and ethically permissible when treatment is no longer in the patient's best interests or is futile. Not the same as killing
- Doctrine of double effect: giving medication (e.g. morphine) to relieve suffering is lawful even if it may hasten death, provided the PRIMARY INTENTION is symptom relief and the dose is proportionate
- Euthanasia (active killing): ILLEGAL in the UK — both voluntary and involuntary. A doctor who intentionally causes death commits murder/manslaughter
- Assisted suicide: illegal in the UK under the Suicide Act 1961 (section 2). Travelling abroad for assisted dying (e.g. Dignitas) is not directly an offence for the person seeking it, but assisting may be prosecuted
- Airedale NHS Trust v Bland (1993): landmark case — withdrawal of CANH from a patient in PVS is lawful if it is not in their best interests to continue treatment. This is NOT euthanasia
Overview
End-of-life care raises complex ethical questions at the intersection of medicine, law, and personal values. Key principles include: the sanctity of life (but not an absolute obligation to prolong life at all costs), respect for patient autonomy (including the right to refuse life-sustaining treatment), the best interests framework for patients who lack capacity, and the doctrine of double effect (permitting symptom relief even if it may shorten life). UK law draws a clear distinction between lawful withdrawal/withholding of treatment (letting die) and unlawful active killing (euthanasia). NICE NG31 (Care of dying adults in the last days of life) and NG142 (End of life care for adults) provide clinical guidance.
Epidemiology
Approximately 550,000 people die in England and Wales each year. Around 75% of deaths are expected, and the majority could benefit from palliative care. However, only about 50% of people who would benefit currently receive specialist palliative care input. End-of-life ethical dilemmas are among the most commonly tested topics in the UKMLA. Assisted dying is one of the most debated topics in UK medical ethics — the BMA moved to a neutral position in 2021 but returned to opposing a change in the law in 2023. The Terminally Ill Adults (End of Life) Bill was introduced to Parliament in 2024.
Key Ethical Concepts
Symptoms
Withdrawal of treatment: stopping a treatment that is no longer providing benefit (e.g. stopping dialysis, removing ventilation). Legally equivalent to withholding — both are permissible when treatment is not in best interests
Doctrine of double effect: an action with a good primary intention (relieve pain) that has a foreseeable but unintended bad consequence (hasten death) is ethically and legally permissible
Active euthanasia: deliberately causing death with the intention of ending suffering. ILLEGAL in the UK regardless of patient's wishes
Assisted suicide: helping someone to take their own life (e.g. providing lethal medication). Illegal under Suicide Act 1961. DPP Prosecution Policy (2010) provides factors for and against prosecution
Palliative sedation: reducing consciousness to relieve otherwise refractory symptoms at end of life. Legal and ethical if proportionate and with appropriate intent
Clinically assisted nutrition and hydration (CANH): considered a medical treatment (not basic care) — can be withdrawn if not in patient's best interests (Bland case)
Signs
A competent adult can refuse any treatment including life-sustaining treatment — even if death will result. This is NOT suicide or euthanasia
Nobody — patient, family, or court — can DEMAND treatment that a doctor considers futile or not in the patient's best interests
Legal Framework
First-line
Bland case (1993)Airedale NHS Trust v Bland: withdrawal of CANH from a patient in persistent vegetative state is lawful if treatment is not in their best interests. Treatment can be withdrawn but the patient must not be actively killed. Court authorisation was required — now only needed for disputed or novel cases
Pretty case (2002)R (Pretty) v DPP: confirmed that assisted suicide is illegal and there is no right to die under the Human Rights Act. Article 2 (right to life) does not include a right to death
Second-line
DPP Prosecution Policy on Assisted Suicide (2010)Lists factors for/against prosecution: compassion and genuine wishes of the person favour no prosecution; financial gain, pressure, or the suspect being a healthcare professional favour prosecution
Burke case (2005)R (Burke) v GMC: confirmed that patients cannot demand treatment — a doctor is not obliged to provide treatment they consider futile or not clinically indicated
Specialist
Court of ProtectionFor disputed cases involving withdrawal of CANH or life-sustaining treatment in patients who lack capacity and there is no agreement between clinical team and family
1
Principles of end-of-life care
- Patient autonomy: respect the wishes of competent patients, including refusal of treatment
- If patient lacks capacity: act in best interests, considering advance decisions, LPA, known wishes
- Good palliative care: manage pain, breathlessness, nausea, anxiety, spiritual needs
- Anticipatory prescribing: prescribe as-needed medications for common symptoms in last days (pain, agitation, secretions, nausea)
2
Withdrawal of treatment
- Withdrawal is lawful when treatment no longer provides net benefit or is not in patient's best interests
- Discuss with patient (if has capacity), family, and clinical team
- If disagreement → seek second opinion, clinical ethics committee, or court
- Ensure patient comfort throughout — palliate symptoms actively
3
What doctors MUST NOT do
- Must not intend to cause or hasten death
- Must not administer a lethal dose with the intention of ending life
- Must not assist a patient to end their own life
- Must not abandon a patient — even if the patient is dying, the doctor has a duty to provide comfort and dignity
Complications
- Moral distress: Healthcare professionals may experience significant ethical distress in end-of-life decisions
- Family conflict: Disagreements about withdrawal of treatment are common and emotionally charged
- Legal risk: If the line between lawful palliation and unlawful killing is blurred, there is risk of criminal investigation
- Under-treatment of symptoms: Fear of hastening death leading to inadequate pain relief — the doctrine of double effect exists precisely to prevent this
UKMLA Exam Tips
- 1Withdrawing futile treatment is NOT euthanasia — it is good medical practice. The law treats withholding and withdrawing equivalently
- 2Doctrine of double effect: intention matters. If intent is to relieve pain and the dose is proportionate → lawful, even if death may be hastened
- 3Euthanasia is ILLEGAL in the UK regardless of consent. Assisted suicide is also illegal under the Suicide Act 1961
- 4CANH is a medical treatment (Bland case) — not basic care. It can be withdrawn like any other treatment if not in best interests
- 5A patient CAN refuse life-sustaining treatment — even if they will die. This is autonomy, not suicide
- 6Nobody can DEMAND treatment that a doctor considers futile (Burke case)
- 7Know the key cases: Bland (CANH withdrawal), Pretty (no right to die), Burke (no right to demand treatment)
