Withdrawing Non-Beneficial Dialysis in a Patient Without Decision-Making Capacity
An 84-year-old man with end-stage kidney disease on hemodialysis three times weekly, heart failure (EF 25%), and a recent hip fracture has been hospitalized for 3 weeks. He now has delirium, is unable to participate in decisions, and has been declining functionally; he can no longer transfer and has pressure injuries. His documented advance directive states: 'If I am not able to recognize my family and have no reasonable chance of recovery, I do not want dialysis or machines to keep me alive.' His daughter (health care agent) says 'Dad would never want to live like this,' but his son insists 'we keep doing everything - he's a fighter.' The nephrologist is uncertain whether stopping dialysis constitutes 'withdrawing care.'
1. How should the team weigh the advance directive, the surrogate disagreement, and the concept of withdrawing versus withholding?

Ethical/legal reasoning:
- Ethically and legally, withdrawing a life-sustaining treatment (dialysis) is treated the same as withholding it. There is no moral or legal distinction that requires continuing a treatment once it is judged non-beneficial or inconsistent with the patient's values.
- The advance directive is applicable: it names a functional threshold (not recognizing family, no reasonable chance of recovery) that this patient arguably meets. Documented patient wishes carry more weight than surrogate preferences.
- Surrogate disagreement does not override a clear prior directive. The team's job is to interpret the directive faithfully, not to poll the family.
- The son's dissent should be heard and addressed, but 'we do everything' cannot compel a treatment the patient refused in advance.
Process: confirm capacity (delirium = no capacity), locate and validate the directive, hold a structured family meeting, and if conflict persists, involve the ethics committee and possibly palliative care mediation. Document the reasoning thoroughly.
2. Outline the clinical steps to discontinue dialysis compassionately and manage expected symptoms, and describe how you would handle the son's objection in the family meeting.

Clinical steps:
- Confirm the decision through the documented process (directive + agent consensus + ethics input if needed).
- Stop scheduled dialysis; do not stop comfort care. Transition goals explicitly to comfort.
- Anticipate symptoms of uremia over days to ~1–2 weeks: fatigue, nausea, pruritus, dyspnea from volume overload, and possible myoclonus/seizures.
- Pre-emptive orders: an opioid (e.g., morphine or hydromorphone) for dyspnea/pain, an antiemetic (e.g., haloperidol or metoclopramide), antipruritic measures, and a benzodiazepine for anxiety or seizure prophylaxis if indicated. Note: with dialysis stopped, renal clearance is absent - dose opioids cautiously and prefer agents with less problematic metabolites (e.g., fentanyl, hydromorphone at reduced doses).
- Reduce fluid intake to comfort; use mouth care for thirst.
- Engage hospice; ensure a Do-Not-Hospitalize plan if consistent with goals.
Handling the son: acknowledge his love and fear, explore what 'fighter' means to him, and reframe comfort as a form of care rather than giving up. Be explicit that we are not abandoning his father. Offer chaplain/social work and time; avoid debating him in front of others. Document his dissent and the team's rationale.
