Kt/V for Dialysis Adequacy

Measures adequacy of haemodialysis. Kt/V represents clearance (K) × time (t) / volume of distribution (V). Target: single-pool Kt/V ≥1.4 (KDOQI) or URR ≥65%.

Score interpretation

Inadequate Dialysis 0–1.19

Kt/V <1.2 — inadequate dialysis; associated with increased morbidity and mortality

→ Increase dialysis time or frequency; check vascular access flow; review blood flow rate; consider increasing Qb or Qd; dietitian review

Borderline Adequate 1.2–1.39

Kt/V 1.2–1.4 — borderline adequacy (minimum acceptable threshold)

→ Aim for higher Kt/V; consider extending session time; review access function

Adequate Dialysis 1.4–9

Kt/V ≥1.4 — adequate haemodialysis per KDOQI guidelines

→ Maintain current prescription; monitor monthly URR and Kt/V; nutritional monitoring

Interpretation bands for the Kt/V. Apply clinical judgement and local guidance.
