Withholding and Withdrawing Treatment

There is no ethical or legal distinction between withholding and withdrawing treatment, and both are permissible when continued treatment is no longer in the patient's best interests, is refused by a competent patient, or is considered futile.

Key Facts

No ethical or legal distinction between withholding and withdrawing treatment — both are permissible when treatment is not in the patient's best interests A competent patient can refuse any treatment, even if refusal leads to death (Airedale NHS Trust v Bland [1993]) Withdrawing treatment is NOT the same as euthanasia or assisted suicide — it is allowing the underlying disease to take its natural course Clinically assisted nutrition and hydration (CANH) is considered medical treatment and can be withdrawn (Bland [1993]) Court of Protection application for CANH withdrawal was previously required but Y v An NHS Trust (2018) confirmed this is not always necessary if clinical team and family agree The doctrine of double effect permits treatment that may hasten death if the primary intention is symptom relief GMC guidance: doctors should not provide treatments that are not clinically indicated or are not in the patient's best interests All decisions should be made through a best interests process when the patient lacks capacity

Overview

Key Facts

The decision to withhold or withdraw treatment is one of the most ethically and emotionally challenging in medicine. UK law is clear that there is no obligation to provide treatment that is futile or not in the patient's best interests, and that a competent refusal must be respected.

Legal Framework

  • Common law: no obligation to provide futile treatment; competent refusal is binding
  • Mental Capacity Act 2005: best interests framework for patients lacking capacity
  • Human Rights Act 1998: Article 2 (right to life — does not require futile treatment), Article 3 (prohibition of inhuman/degrading treatment), Article 8 (right to respect for private life)
  • Airedale NHS Trust v Bland (1993): landmark case; withdrawal of CANH from patient in persistent vegetative state lawful
  • Y v An NHS Trust (2018): Court of Protection application not always required for CANH withdrawal if medical team and family agree

Key Ethical Principles

  • Equivalence: withholding and withdrawing are ethically equivalent (though withdrawing may feel more difficult emotionally)
  • Acts vs omissions: allowing natural death by withdrawing treatment is not killing; the underlying disease causes death
  • Proportionality: balance burden of treatment against potential benefit
  • Doctrine of double effect: providing pain relief that may hasten death is permissible if primary intention is symptom relief
  • Patient autonomy: competent refusal of treatment must be respected

Clinical Presentation

Common Clinical Scenarios

  • Withdrawing mechanical ventilation in a patient with no prospect of recovery
  • Withdrawing CANH in persistent vegetative state or minimally conscious state
  • Not escalating to ICU for a patient with end-stage organ failure
  • Withdrawing dialysis for a patient who chooses conservative management
  • Not starting antibiotics for a patient in the terminal phase of illness
  • Stopping chemotherapy when disease has progressed despite treatment

Considerations

  • Is the treatment providing benefit to the patient?
  • Is the treatment achieving its intended goal?
  • What is the patient's prognosis with and without treatment?
  • What are the burdens of continued treatment?
  • What are the patient's wishes (current, past, advance decisions)?
  • What would the patient have wanted (if unable to express wishes)?
  • Have all reasonable treatment options been considered?

Red Flags

  • Withdrawing treatment without proper best interests process
  • Failing to involve family in decision-making
  • Withdrawing treatment as cost-saving measure rather than best interests
  • Not providing adequate palliative care alongside withdrawal
  • Confusion between withdrawal of treatment and euthanasia

Differential Diagnosis

Withdrawing treatment (best interests)LawfulTreatment no longer in patient's best interests
Respecting competent refusalLawful (and required)Patient autonomy
Euthanasia (intentional killing)Unlawful (murder)Illegal in UK
Assisted suicideUnlawful (Suicide Act 1961)Illegal in UK
Double effect (symptom relief hastening death)LawfulPrimary intention is symptom relief

Diagnosis / Investigation

Decision-Making Process

  1. Assess patient's capacity for the decision
  2. If capacity: discuss and respect their wishes
  3. If no capacity: best interests process (MCA 2005)
  4. Consult MDT, family/carers, IMCA if needed
  5. Consider: patient's past wishes, beliefs, values
  6. Consider: clinical prognosis, treatment burdens vs benefits
  7. Consider: ADRT, LPA, ReSPECT form
  8. Document decision, process, and those consulted
  9. Seek second clinical opinion if uncertain
  10. Court of Protection application if disputed or complex (CANH withdrawal in MCS)

Management

Withdrawal of Treatment

  • Ensure adequate symptom management (anticipatory medications)
  • Provide emotional support to family and staff
  • Maintain comfort and dignity
  • Withdraw non-beneficial treatments gradually where appropriate
  • Continue all comfort measures
  • Allow family to be present
  • Provide chaplaincy/spiritual care if requested

Specific Situations

CANH withdrawal:

  • Court of Protection application: not always required if medical team and family agree (Y v NHS Trust 2018)
  • But consider application if: disagreement between team and family, clinical uncertainty, novel case
  • BMA/RCP guidance provides framework

Ventilation withdrawal:

  • Ensure adequate sedation and analgesia before withdrawal
  • Opioids and benzodiazepines as anticipatory medications
  • Suction as needed for comfort
  • Family support and preparation

Referral Criteria

  • Disagreement with family: mediation, second opinion, Court of Protection
  • Complex ethical issues: clinical ethics committee
  • CANH withdrawal in minimally conscious state: consider Court of Protection
  • Paediatric cases: seek specialist and legal advice

Prognosis

  • Appropriate withholding/withdrawal of treatment enables dignified death
  • Most end-of-life deaths in hospitals involve some form of treatment limitation
  • Good communication reduces distress for families and staff
  • Legal framework is well-established but cases continue to clarify (e.g. Charlie Gard, Alfie Evans — paediatric cases)
  • Emotional impact on healthcare professionals significant; debrief and support should be offered

Other Relevant Information

Doctrine of Double Effect

ElementRequirement
The act itselfMust be good or morally neutral (e.g. giving pain relief)
IntentionMust be to relieve suffering (not to cause death)
Foreseen consequenceMay include hastening death
ProportionalityBenefit of symptom relief must outweigh risk of hastening death
