Advanced Dementia, a Proxy's Demand for a PEG, and a Documentation Request
You are the dietitian on a palliative care unit. Mrs. L is an 84-year-old woman with advanced Alzheimer's disease, a Mini-Mental State Examination score of 8/30, and a 6-month history of progressive dysphagia. She now takes only a few teaspoons of pureed food per meal and has lost 7 kg in 5 months (current weight 45 kg, height 1.55 m). Two years ago, while still cognitively intact, she completed an advance directive stating that she did not want 'tube feeding or machines to keep me alive' if she could no longer recognize her family. Her daughter, who is the health care proxy, insists that a percutaneous endoscopic gastrostomy (PEG) tube be placed and says the team is 'starving her mother.' The daughter also asks you to document that a specific oral nutrition supplement is 'medically necessary' so that her mother's insurance will cover it, although the product is not indicated for her. The attending physician asks for your recommendation.
1. Set out the ethical reasoning and give your recommendation about the PEG.

Ethical framework. Respect for autonomy is expressed through Mrs. L's prior advance directive, made when she had capacity. The daughter is proxy, not decision-maker in her own right; her role is substituted judgment-what her mother would have chosen.
Beneficence and nonmaleficence. In advanced dementia, PEG feeding has not been shown to prolong survival, improve quality of life, reduce aspiration pneumonia, or heal pressure ulcers; it can increase restraint use, edema, and aspiration of secretions. Hand feeding with comfort measures is the appropriate intervention. The directive and the clinical evidence point the same way.
Recommendation. Recommend no PEG; continue comfort-focused hand feeding, oral care, and speech-language pathology-guided texture modification. Acknowledge the daughter's distress and offer a palliative care or ethics consult. If conflict persists, follow institutional dispute-resolution policy. Document capacity assessment, the directive, and the process. Do not frame it as 'starving'-explain that the disease is causing progressive swallowing failure and that comfort feeding is active care.
2. How would you communicate with the daughter in the next conversation? Give concrete language and a structure.

Start by naming her experience: 'You are trying to do right by your mother, and this is frightening.' Ask what she has seen-perhaps her mother eating less-and what she believes a tube will achieve. Then explain, in plain language, what the evidence shows and what hand feeding can offer: pleasure, taste, contact, and comfort, without the burdens of a tube.
Use substituted judgment: 'If she could tell us now, what would she say?' Remind her gently of the directive without shaming her. Offer a time-limited trial of intensive comfort feeding with clear goals and a review date, rather than an immediate yes or no. Bring in palliative care and, if needed, ethics. Provide written information and allow silence. The goal is a shared plan that honors the patient, not winning the argument.
3. The daughter asks you to document the supplement as 'medically necessary' when it is not indicated. What do you do?

I cannot document that a product is 'medically necessary' if it is not indicated; that is a false statement and a billing-integrity issue. I would explain this clearly but kindly, then offer legitimate paths: review the insurer's criteria, check whether a covered product meets her needs, or document the clinical rationale accurately if there is a genuine indication.
If the supplement is not indicated, the answer is no. Offer alternatives-food fortification or a covered oral nutrition supplement based on actual need. Document the request and my response factually. If a colleague pressures me, I would involve my supervisor or compliance. The therapeutic relationship with the daughter can survive a clear boundary; it is damaged more by collusion that later unravels.
