Summary

  • Examples are ventilation, dialysis, CPR and feeding through a tube.
  • An adult with capacity can refuse it, even if they will die as a result.
  • For a patient who lacks capacity, it can be withheld or withdrawn when continuing is not in their best interests.
  • When doctors and a family cannot agree, the dispute can be taken to a court.

Interview questions

  • Is there a moral difference between withholding a treatment and withdrawing it?
  • A family wants treatment continued and the doctors believe it is causing suffering. How should that be resolved?
  • Should feeding through a tube count as medical treatment?
