The old 'start dialysis early' practice (eGFR ~10-15 without symptoms) was tested and found to give NO benefit — so the pendulum moved to 'start when symptoms or complications demand it,' usually eGFR 6-10. Delaying past symptoms, though, is genuinely harmful.
The IDEAL trial randomized patients to early (eGFR 10-14) vs late (eGFR 5-7) dialysis starts — survival, quality of life, and costs were identical. 'Early starts' are no longer recommended; they risk dialysis without benefit.
The modern approach (KDIGO 2024): individualized start based on symptoms (nausea, fatigue, itching, fluid overload), not a number alone. Most start between eGFR 6-10.
The reverse error is also common: waiting until emergency complications (pulmonary edema, uremic encephalopathy, severe hyperkalemia) forces unplanned urgent dialysis — which has worse outcomes and misses elective access (fistula) planning.
The real determinant of outcomes is not the start number — it's starting with a MATURE vascular access (fistula/graft) rather than a catheter.
