Design: Prospective randomised cross-over study. Fifty-two eligible patients will be randomised to a treatment time of either 6 hours or 4 hours for a period of 24 weeks and following a washout period of 4 weeks, switch to the alternative treatment time for an additional 24 weeks.

Aims: To examine the feasibility and effect of extended dialysis treatment time, 6 hours thrice weekly, versus the standard, 4 hours thrice weekly, comparing the differences from baseline in outcome measures over a total 12-month period.

Primary outcome measure

1]Serum albumin

Secondary outcome measures Nutritional status

  1. Malnutrition-inflammation score
  2. Dietary intake
  3. Hand-Grip strength
  4. Energy expenditure

Quality of life

  1. Patient reported quality of life and
  2. time to recovery from dialysis

Serum biomarkers

  1. BNP
  2. Troponin
  3. MCP-1

Others 24- hour Ambulatory blood pressure 24-hour accelerometer
