Two Siblings, One Proxy Form, and Advanced Dementia
Mrs. T, 84, has advanced Alzheimer disease; she is chair-bound, speaks fewer than six words, and is dependent for all ADLs. She has been admitted twice in six months with aspiration pneumonia and has lost 12 lb in three months; a bedside swallow evaluation shows silent aspiration with thin liquids. She has no written advance directive and lacks decision-making capacity. Her daughter, who is her health care agent under a state proxy form, insists on 'full code, and put in a feeding tube - she's a fighter.' Her son, who lives out of state, says their mother told him repeatedly after their father's death that she never wanted 'tubes or machines.' The team asks you to lead a family meeting.
1. Who is the decision-maker, and by what standard? How do you handle the conflict between the two siblings, and what would you refuse to do?
Read the worked answer
Confirm capacity first, and document it. She cannot understand the options, weigh them, or communicate a choice - she lacks decision-making capacity for this decision. That is a specific, decision-specific finding, not a global label of 'incompetent.'
Who decides. The daughter holds the legal authority under the state proxy form. She is the surrogate. But a surrogate is not a free agent: she is obligated to use substituted judgment - what would Mrs. T have chosen - and only falls back on best interests if the patient's wishes are genuinely unknown.
How the son's information fits. His report that she repeatedly said she never wanted 'tubes or machines' is not a competing vote; it is evidence of the patient's own values, and it is arguably the best evidence available, since it is a specific statement about exactly this situation. It must be taken seriously, documented verbatim, and put to the daughter. The son does not outrank the daughter, and the daughter does not get to ignore her mother's stated wishes.
What I would refuse to do
- I would not write a DNR or a comfort-only plan unilaterally, over the objection of the legal surrogate, no matter how clinically sensible it seems. That is the fastest way to convert a disagreement into a lawsuit and a family into an enemy.
- Nor would I let the daughter's preference be recorded as the patient's wish without examining it. 'She's a fighter' is a statement about the daughter, not about the patient.
The move that resolves most of these: separate emotion from decision. Explore why the daughter is insisting - guilt, a fear that agreeing to comfort care means she 'killed her mother,' religious belief, or a prior experience of a relative who died after a DNR. Name it. Then ask her directly: 'If your mother could sit up and tell us what she wants, what do you think she would say?' Most surrogates, given room, answer honestly.
If the conflict remains irreconcilable: ethics consultation, and follow the state's dispute-resolution mechanism (which may involve an ethics committee opinion, a second physician, or a court-appointed guardian). Do not shortcut this.
2. What evidence do you present at the meeting about feeding tubes and about CPR in advanced dementia, and how do you frame it without lecturing?
Read the worked answer
Frame the goals before the interventions. Open with: 'Before we talk about any specific machine or tube, tell me what you want for your mother. Is it more time, or is it comfort and being left in peace?' Decisions made inside a stated goal are far more stable than decisions made intervention by intervention.
Feeding tube - what the evidence actually shows in advanced dementia
- It does not prolong survival in this population.
- It does not reduce aspiration pneumonia; observational data suggest tube feeding does not prevent aspiration and may increase aspiration of gastric contents. Her aspiration is from oropharyngeal dysphagia and silent aspiration - a tube does not fix the swallowing problem.
- It does not heal or prevent pressure ulcers.
- It does carry procedural and tube-related complications, and often leads to restraints and reduced human contact.
- Hand feeding with a comfort-feeding approach - small bites, preferred foods, upright positioning, oral care - is the guideline-endorsed alternative and preserves both nutrition-by-mouth pleasure and dignity. This is supported by geriatrics and palliative care societies.
CPR
- For a patient with advanced dementia and poor functional status, survival to discharge after in-hospital cardiac arrest is low - on the order of 10% or less in most series - and survivors frequently have worse functional status than before the arrest.
- Intubation and ICU care in this setting often produces a prolonged dying process in an unfamiliar environment rather than a meaningful recovery.
- Say this as ranges and uncertainty, not as a guarantee. 'I cannot tell you she will die if we do this. I can tell you it rarely works, and when it does, it usually does not give back the person you knew.'
Tone matters more than the data. Do not deliver a lecture on the evidence. Ask what her mother valued, reflect it back, offer a recommendation ('If she were my mother, I would focus on comfort - here is why'), and give the family time. Silence is a tool; use it.
Practical sequencing: discuss the feeding tube and code status in separate conversations if the daughter is overwhelmed. A surrogate who cannot yet say 'DNR' may still be able to say 'no feeding tube.' Take the yes you can get, and revisit.
3. Assume the family reaches a comfort-focused consensus. What orders, documentation, and coordination must be in place before you leave the unit, and what do you do if the daughter changes her mind at 2 a.m.?
Read the worked answer
Document the process, not just the outcome. The note must contain: the capacity determination; who holds proxy authority; direct quotations of the patient's prior statements as reported by the son; what the daughter said and the concerns behind it; the options and likely outcomes as explained; the recommendation offered; and the decision reached, with who agreed. A comfort-care plan without a documented conversation is indefensible at 2 a.m. and in court.
Orders to write before leaving
- Code status: DNR/DNI, obtained through surrogate consent in whatever form the state and hospital require. Do not enter a unilateral DNR.
- Discontinue non-beneficial interventions: routine labs, fingersticks, telemetry, unnecessary medications (statins, bisphosphonates, glycemic agents, preventive agents), and antibiotics whose only purpose is prolonging the dying process.
- Symptom management: opioids titrated for dyspnea and pain (dyspnea is treated with opioids, not with oxygen alone), anxiolytics for agitation, anticholinergics for secretions, scheduled oral care, bowel and bladder care, skin care, positioning.
- Comfort feeding order written explicitly: hand feeding, aspiration precautions, preferred foods, no restrictive diets, family may feed, stop if she shows distress. This prevents a well-meaning night nurse from putting in a nasogastric tube 'because she was ordered nothing by mouth.'
Coordination
- Notify nursing and the covering clinician in person and in writing.
- Palliative care consult at the bedside; hospice referral is appropriate given the trajectory (recurrent aspiration, weight loss, FAST stage consistent with severe dementia, prognosis likely under six months).
- Review the plan with the primary care clinician and the nursing home or home caregiver, and send the documented goals of care with her.
If the daughter changes her mind at 2 a.m.: honor the surrogate's authority. Reversible comfort measures continue; CPR and transfer to the ICU can be reinstated while the team re-discusses in daylight. Do not treat a change of heart as a betrayal of the plan - grief oscillates, and the correct response is to reconvene the family meeting, involve palliative care, and consider a time-limited trial with explicit criteria for stopping. Reaffirm the patient's own stated wishes as the anchor, document the new discussion, and never make the family feel punished for ambivalence.
