Management of Uremic Encephalopathy in Patients Refusing Dialysis

Initial Approach to the Patient

The decision to initiate dialysis represents a joint decision by patient and physician, reflecting their mutual understanding of the compromises and uncertainties, as acknowledged by the American Journal of Kidney Diseases 1
Patients have the right to refuse dialysis, and this decision should be honored if they have decision-making capacity and are fully informed, according to the Journal of the American Society of Nephrology 2

Implement regular symptom screening using validated tools to identify and address the most bothersome symptoms, as recommended by clinical guidelines 3
Focus on managing symptoms that are most distressing to patients with uremic encephalopathy, including confusion, sleep disturbances, and fatigue, as suggested by clinical guidelines 3
Control phosphate intake through dietary modifications and appropriate use of phosphate binders, as recommended by clinical guidelines 3
Maintain appropriate protein intake to prevent malnutrition while avoiding excessive nitrogenous waste production, as recommended by clinical guidelines 3
Consider low-protein diets and ketoanalogs of essential amino acids to minimize uremic symptoms, as suggested by the American Journal of Kidney Diseases 4

Use loop diuretics and sodium polystyrene sulfonate to help maintain volume homeostasis and control electrolyte imbalances, as recommended by the American Journal of Kidney Diseases 4
Consider nitrogen-scavenging agents in cases of severe hyperammonemia contributing to encephalopathy, as suggested by clinical guidelines 5

Ensure the patient's decision to refuse dialysis is informed by discussing the natural course of uremic encephalopathy and the benefits and burdens of treatment, as recommended by the Journal of the American Society of Nephrology 2
Consider offering a time-limited trial of dialysis for patients with uncertain prognosis or when a consensus cannot be reached, as suggested by the Journal of the American Society of Nephrology 2

All patients who decide to forego dialysis should receive continued palliative care, as recommended by the Journal of the American Society of Nephrology 2
With the patient's consent, involve hospice healthcare professionals in managing the medical, psychosocial, and spiritual aspects of end-of-life care, as suggested by the Journal of the American Society of Nephrology 2

Be prepared to revisit the decision about dialysis if the patient's condition or wishes change, as recommended by the American Journal of Kidney Diseases 1

Avoid focusing solely on laboratory values when determining the severity of uremic encephalopathy; consider the whole patient including symptoms and quality of life, as recommended by clinical guidelines 3
Recognize that the evidence supporting specific medical therapies in managing uremic encephalopathy without dialysis is generally of low quality, as noted by clinical guidelines 3
