Ethical Conflict: Terminal Patient's Family Requests Aggressive Nutrition Support
An 84-year-old woman with advanced metastatic pancreatic cancer, cachexia (weight loss 15% over 3 months, BMI 17), and a prognosis of weeks is admitted with aspiration pneumonia. She has moderate dysphagia and is drowsy but intermittently lucid. She has an advance directive stating she does not want 'artificial feeding' if she is dying, and she appointed her daughter as healthcare proxy. The daughter insists that 'she would want to fight' and requests a percutaneous endoscopic gastrostomy (PEG) tube. The medical team is divided; one physician says 'we should do everything.' The patient, when briefly lucid, says she is 'tired' and 'wants to go home.'
1. Analyze the ethical principles at stake and how they apply to this situation.

Principles:
- Autonomy: The patient's advance directive and her lucid statements ('tired,' 'wants to go home') reflect her values. Her prior competent wishes should guide care. The daughter's proxy authority is to interpret the patient's wishes, not to substitute her own.
- Beneficence: Would a PEG benefit her? In advanced cancer with cachexia and aspiration pneumonia, PEG placement carries procedural risk and does not reverse cachexia or improve survival; it may increase aspiration risk and discomfort. The likely benefit is low.
- Non-maleficence: PEG insertion in a dying patient may cause harm (infection, bleeding, discomfort, restraint use).
- Justice: Resource allocation is secondary here but relevant in a public system.
- Futility: The intervention is unlikely to achieve its intended goal of meaningful recovery.
Application: The advance directive should be honored. The daughter's request, while emotionally understandable, conflicts with the patient's documented wishes. The team should not override the directive based on family pressure alone.
2. What is your role as the dietitian in this conflict, and what would you communicate to the family and team?

Role: I am not the decision-maker, but I provide clinical information and support the team's ethical process. I should:
- Clearly state the nutritional prognosis: in advanced cancer cachexia, artificial nutrition does not reverse cachexia or improve survival; it may cause fluid overload, aspiration, and discomfort.
- Correct misconceptions: 'feeding = comfort' is not always true; food and fluids can be symbolic, and families often equate feeding with caring.
- Offer alternatives: comfort-focused oral care, small pleasurable tastes if safe, and management of symptoms (pain, nausea, dysphagia).
- Support the daughter: acknowledge her distress, explore her fears ('I don't want her to starve'), and explain that anorexia-cachexia is part of the disease, not starvation.
- Recommend an ethics consult and palliative care involvement.
Communication with the team: Document the discussion, advocate for honoring the advance directive, and ensure the patient's lucid statements are recorded. Avoid unilateral decisions; work through the team and, if needed, the ethics committee.
3. How would you handle the situation if the daughter remains insistent and the patient's capacity fluctuates?
Read the worked answer
Process:
- Assess capacity formally - fluctuating capacity requires assessment at a lucid moment; document findings. If the patient lacks capacity at the time of decision, the advance directive and prior wishes govern.
- Follow the jurisdiction's legal framework - in many systems, a valid advance directive is binding; the proxy cannot override it. Escalate to the ethics committee and, if necessary, legal/risk management.
- Mediation: involve a palliative care physician or social worker to facilitate a family meeting. Explore the daughter's underlying fears and offer reassurance about comfort care.
- Do not abandon the family - continue to provide emotional support and information.
- Document everything - the patient's statements, the advance directive, the family's requests, and the team's reasoning.
Key point: The dietitian's role is to provide honest prognostic information and support the ethical process, not to make the final decision. The goal is to align care with the patient's values while supporting the family through grief.
