Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects randomized to the Early dialysis initiation: commence dialysis as soon as possible with a target glomerular filtration rate (GFR) of 10-14 ml/min/1.73m^2.
Dialysis type and regimen used (haemodialysis or peritoneal dialysis) is determined by the caring renal physician.
Intervention code [1] 4077 0
Treatment: Devices
Comparator / control treatment
Subjects randomized to the Late dialysis initiation: delay the commencement of dialysis until their GFR is between 5-7 ml/min/1.73m^2.
Dialysis type and regimen used (haemodialysis or peritoneal dialysis) is determined by the caring renal physician.
Control group
Active

Outcomes
Primary outcome [1] 5463 0
All cause mortality
Timepoint [1] 5463 0
At the end of the trial. 800 patients will be followed every 3 months for a minimum of 3 years post randomization.
Secondary outcome [1] 9202 0
Quality of life as measured by using the following research tools:
Health Utilities Index III (HUI III), a multi-attribute generic instrument for measuring quality of life;
Assessment of Quality of Life (AQoL), another multi-attribute generic instrument for measuring quality of life;
Kidney Disease Quality of Life (KDQOL), a disease-specific instrument for measuring quality of life.
Timepoint [1] 9202 0
Health Utilities Index III (HUI III) is completed by each patient at baseline and every three months thereafter;
Assessment of Quality of Life (AQoL) is also completed by each patient at baseline and every three months thereafter;
Kidney Disease Quality of Life (KDQOL) is completed by each patient at baseline and every 12 months thereafter.
Secondary outcome [2] 9203 0
Cost of treatment:
Health Services Utilisation (HSU), an instrument used to collect data on use of hospital resources; and
Patient Diary, an instrument used to collect data on use of community resources.
A separate review of the cost of dialysis in Australia and New Zealand has also been performed and comparisons will also be made with other already published data.
Timepoint [2] 9203 0
Health Services Utilisation (HSU) is completed for each patient every 3 months after baseline (but not at baseline). This form is completed by the study nurse from the patient's hospital records; and
Patient Diary is completed by each patient each month.
Secondary outcome [3] 9204 0
Cardiac echo changes that will be studied include:
a) left ventricular mass;
b) systolic function;
c) diastolic function; and
d) myocardial fibrosis.
Timepoint [3] 9204 0
Cardiac echo changes will be reviewed in each subject at 0, 6 and 12 months and also just prior to the commencement of dialysis in patients randomized to the late start group.
Secondary outcome [4] 9205 0
Nutrition will be assessed using the following measures:
a) Total body nitrogen assessment using prompt neutron activation analysis;
b) Subjective global assessment: a clinical nutrition score;
c) Bioelectrical impedance monitoring; and
c) Serum albumin measurement.
Timepoint [4] 9205 0
At baseline and then every 12 months for 3 years.
