Ethical Decision-Making in a Patient with Dementia and Refusal of Care
Mr. B is an 85-year-old man with moderate-to-severe dementia who resides in an assisted living facility. He has a history of hypertension, atrial fibrillation (on warfarin), and osteoarthritis. He has a living will stating he does not want life-sustaining treatment if he has an incurable condition, but he appointed his son as healthcare proxy. Recently, Mr. B has become increasingly agitated and refuses to take his medications, including warfarin. He also refuses to eat and has lost 8 lbs in 2 weeks. The staff reports he sometimes forgets who his son is and has episodes of aggression. His son insists that "everything be done" and wants the staff to force medications and consider a feeding tube. The staff is concerned about his quality of life and ethical appropriateness of forced treatment.
1. What ethical principles are in conflict in this situation, and how would you apply them?
Read the worked answer
Ethical principles in conflict:
- Autonomy: Mr. B's right to refuse treatment, but his decision-making capacity is impaired by dementia.
- Beneficence: The son's desire to do good by prolonging life and preventing stroke (warfarin) and malnutrition (feeding tube).
- Nonmaleficence: Forcing medications or feeding tube may cause harm, distress, and violate dignity.
- Justice: Fair allocation of resources and respect for the patient's previously expressed wishes.
Application:
- Assess Mr. B's decision-making capacity: likely lacks capacity due to dementia. His living will provides guidance but is vague ("incurable condition").
- The son as proxy should make decisions based on substituted judgment (what Mr. B would have wanted) and best interests. His living will suggests he valued comfort and avoiding life-sustaining treatment. Forcing warfarin (which increases bleeding risk) and feeding tube (which may not improve quality of life in severe dementia) may conflict with his wishes.
- Consider a ethics consultation to mediate conflict between son and staff. Explore son's concerns and provide education about dementia trajectory and risks/benefits of interventions. Aim for consensus, possibly with a time-limited trial of alternative strategies (e.g., liquid warfarin, appetite stimulants).
2. What practical steps would you take to manage his refusal of medications and food while respecting his dignity and the son's concerns?

- Assess for reversible causes: Evaluate for pain, constipation, infection, depression, or medication side effects causing agitation and anorexia. Treat any identified issues.
- Nonpharmacologic approaches: Offer medications with food or in liquid form; use a calm, consistent approach; involve familiar staff; try behavioral distraction. For meals, offer small, frequent, high-calorie snacks; respect food preferences; create a pleasant dining environment.
- Medication review: Reassess necessity of warfarin. Given his dementia and falls risk, consider whether anticoagulation is still appropriate. Discuss with son the risks of bleeding vs. stroke, and alternative options (e.g., DOAC if appropriate, though cost/coverage may be an issue).
- Feeding tube discussion: Explain that in advanced dementia, feeding tubes do not improve survival, quality of life, or prevent aspiration; they may increase agitation and need for restraints. Emphasize hand-feeding and comfort care.
- Family meeting: Involve the son, staff, and possibly a palliative care or ethics consultant. Use empathy, provide clear information, and explore his goals and fears. Document discussions.
- Advance care planning: Clarify the living will and consider updating it with specific guidance. If conflict persists, consult ethics committee or consider legal guardianship if son's decisions are not in Mr. B's best interest.
- Staff support: Debrief with staff, provide ethical framework, and ensure consistent care plan.
