Quick Summary of Life-Prolonging Procedures

Life-prolonging procedures are medical interventions or treatments designed to extend a person’s life when their health is severely compromised or when they are facing a life-threatening condition. These procedures may include cardiopulmonary resuscitation (CPR), mechanical ventilation, dialysis, and other intensive care measures aimed at sustaining vital functions and preventing imminent death. The decision to undergo life-prolonging procedures often involves complex medical, ethical, and personal considerations, including the patient’s wishes, quality of life, prognosis, and potential risks and benefits of the intervention. Advanced directives, such as living wills and healthcare proxies, allow individuals to specify their preferences regarding life-prolonging treatments in advance, ensuring that their wishes are respected even if they are unable to communicate them later. Overall, the use of life-prolonging procedures is guided by a commitment to preserving life while also respecting patients’ autonomy, dignity, and values.

Full Definition Of Life-Prolonging Procedures

Life-prolonging procedures refer to medical interventions that extend the life of a patient who might otherwise die due to a terminal condition or a serious illness. These procedures often include mechanical ventilation, artificial nutrition and hydration, dialysis, and other advanced medical technologies. The legal framework governing these procedures in the UK is complex and involves principles of medical ethics, patient autonomy, and legal statutes. This overview explores the legal landscape, focusing on key legislation, case law, and ethical considerations relevant to life-prolonging procedures in the UK.

Legal Framework

The Human Rights Act 1998

The Human Rights Act 1998 incorporates the European Convention on Human Rights (ECHR) into UK law. Several articles of the ECHR are pertinent to life-prolonging procedures:

  • Article 2: Right to Life – This article obliges the state to protect the right to life. In the context of life-prolonging procedures, this has been interpreted to mean that there is a duty to take appropriate steps to safeguard life, though it does not necessarily mandate the provision of life-prolonging treatment in all circumstances.
  • Article 3: Prohibition of Torture – This article prohibits inhuman or degrading treatment. The prolongation of life against a patient’s wishes, or in a manner that causes significant suffering, may engage this right.
  • Article 8: Right to Respect for Private and Family Life – This article encompasses the right to make decisions about one’s own body and medical treatment, including the refusal of life-prolonging procedures.
The Mental Capacity Act 2005

The Mental Capacity Act 2005 (MCA) is crucial for decisions regarding life-prolonging treatment, especially for individuals who lack the capacity to make decisions for themselves. Key provisions include:

  • Section 1: Principles – This section establishes principles such as the presumption of capacity and the requirement to act in the best interests of the person lacking capacity.
  • Section 4: Best Interests – Decisions must be made in the best interests of the incapacitated person, considering their past and present wishes, feelings, beliefs, and values.
  • Section 5: Acts in Connection with Care or Treatment – Provides legal protection for those making decisions about treatment for incapacitated individuals, provided they act in the person’s best interests.
  • Section 9-14: Lasting Powers of Attorney – Allows individuals to appoint an attorney to make decisions about their health and welfare, including the refusal of life-prolonging treatment, if they lose capacity.
  • Section 24-26: Advance Decisions – Legally binding advance decisions to refuse treatment (including life-prolonging procedures) if specific conditions are met.
The Adults with Incapacity (Scotland) Act 2000

In Scotland, the Adults with Incapacity (Scotland) Act 2000 plays a similar role to the MCA, providing a framework for decision-making on behalf of incapacitated adults. It emphasizes the need to take into account the past and present wishes of the patient and to act in their best interests.

Case Law

Case law has significantly shaped the legal landscape concerning life-prolonging procedures. Some landmark cases include:

Airedale NHS Trust v Bland [1993] AC 789

Tony Bland was in a persistent vegetative state (PVS) following the Hillsborough disaster. The House of Lords ruled that life-prolonging treatment could be lawfully withdrawn if it was in the patient’s best interests. This case established that discontinuing treatment was not an act of euthanasia but rather allowing the patient to die naturally.

Re B (Adult: Refusal of Medical Treatment) [2002] 2 All ER 449

This case involved Ms. B, a tetraplegic patient who wished to discontinue artificial ventilation. The court upheld her right to refuse treatment, affirming the principle of patient autonomy and the right of competent adults to make their own medical decisions, even if it leads to their death.

NHS Trust v Y [2018] UKSC 46

The Supreme Court held that it was not necessary to seek court approval to withdraw clinically assisted nutrition and hydration from patients in PVS if both medical professionals and the patient’s family agreed it was in the patient’s best interests. This decision streamlined the process for making such decisions, reducing the legal and emotional burden on families and healthcare providers.

Ethical Considerations

Ethical considerations play a critical role in decisions regarding life-prolonging procedures. Key ethical principles include:

  • Autonomy: respecting the patient’s right to make informed decisions about their own care.
  • Beneficence: acting in the best interests of the patient to provide benefit and prevent harm.
  • Non-Maleficence: Avoiding the causation of harm. This includes not prolonging suffering through unnecessary medical intervention.
  • Justice: ensuring fair and equitable access to medical treatment and resources.

Decision-Making for Incapacitated Patients

For patients who lack capacity, decisions about life-prolonging treatment must be made following the framework set out in the MCA or the Adults with Incapacity (Scotland) Act. The primary consideration is the patient’s best interests, which includes:

  • Assessing the patient’s past and present wishes and feelings.
  • Consulting with family members and other relevant parties.
  • Considering the patient’s beliefs and values.

Advance Decisions and Lasting Powers of Attorney

Advance decisions (or “living wills”) allow individuals to refuse specific medical treatments in the future when they might lack capacity. For an advance decision to be legally binding, it must be:

  • Made by a person aged 18 or over who had capacity at the time.
  • Explicitly state the treatment to be refused and the circumstances under which it applies.
  • Written, signed, and witnessed if it relates to life-sustaining treatment.

Lasting Powers of Attorney (LPA) for health and welfare can also include decisions about life-prolonging procedures. The appointed attorney must act in the best interests of the donor, considering their wishes and beliefs.

The Role of Healthcare Professionals

Healthcare professionals have a duty to act in the best interests of their patients while respecting their rights and wishes. This involves:

  • Providing clear and comprehensive information about the potential benefits and burdens of life-prolonging treatments.
  • Ensuring that the patient (or their representative) makes an informed decision.
  • Respecting advance decisions and the authority of LPAs.
  • Engaging in shared decision-making with the patient and their family.

Ethical Dilemmas and Practical Challenges

Healthcare professionals often face ethical dilemmas and practical challenges when making decisions about life-prolonging procedures. These can include:

  • Disputes with Families: Families may disagree about what constitutes the patient’s best interests, especially if the patient’s wishes are not well-documented.
  • Resource Allocation: Balancing the needs of individual patients with the wider demands on healthcare resources.
  • Emotional Burden: The emotional toll on healthcare providers making end-of-life decisions.


The legal landscape governing life-prolonging procedures in the UK is shaped by a combination of statutory law, case law, and ethical principles. The Human Rights Act 1998, the Mental Capacity Act 2005, and relevant case law provide a framework for making these challenging decisions, prioritising patient autonomy and best interests. Healthcare professionals must navigate these legal and ethical considerations to ensure that patients receive care that aligns with their wishes and values, balancing the benefits and burdens of life-prolonging treatments. As medical technology advances, the legal and ethical framework will continue to evolve, requiring ongoing reflection and adaptation by all stakeholders involved in end-of-life care.
