Indications for Dialysis in Patients with Impaired Renal Function

Clinical Indications

• The American Journal of Kidney Diseases recommends that dialysis should be initiated based on clinical symptoms and complications of kidney failure, including serositis, refractory acid-base or electrolyte abnormalities, pruritus, inability to control volume status or blood pressure, progressive deterioration in nutritional status despite dietary intervention, or cognitive impairment, typically occurring when GFR is between 5-10 mL/min/1.73 m² 3, 4
• The National Kidney Foundation suggests that uremic complications such as pericarditis, encephalopathy, seizures, or uremic neuropathy are absolute indications for urgent/emerget dialysis 3, 5
• Refractory volume overload unresponsive to diuretic therapy is a critical indication for dialysis initiation 6, 7
• Severe metabolic acidosis that cannot be controlled medically is a significant indication for dialysis 6, 7
• Progressive hyperphosphatemia with risk of calcium-phosphate precipitation is a critical consideration for dialysis initiation 7

GFR Considerations

• The American Journal of Kidney Diseases states that a GFR of 5-10 mL/min/1.73 m² is typically associated with the development of uremic symptoms, but timing of dialysis initiation should be individualized based on symptom burden 3, 4
• A GFR of less than 15 mL/min/1.73 m² is defined as kidney failure, with approximately 98% of US patients beginning dialysis below this threshold 8
• The American Journal of Kidney Diseases recommends considering preemptive living donor kidney transplantation for patients with a GFR of less than 20 mL/min/1.73 m² and progressive, irreversible CKD over 6-12 months 3, 4

Special Populations

• The American Journal of Kidney Diseases suggests that older adults with diabetes and hypertension have higher competing mortality risks, and dialysis initiation should weigh potential benefits against burdens 3
• Conservative management with comprehensive palliative care is a reasonable alternative for older adults with limited life expectancy or who wish to avoid medical interventions 4

Pre-Dialysis Preparation

• The American Journal of Kidney Diseases recommends that patients with progressive CKD should be managed in a multidisciplinary setting with access to dietary counseling, education about different renal replacement therapy modalities, vascular access planning and placement, and psychological and social support 3, 4, 5
• The American Journal of Kidney Diseases suggests that preserving peripheral veins in patients with stage III-V CKD can facilitate future hemodialysis access 3
