Condition
Kidney failure/haemodialysis
Intervention
All patients were treated for 4 weeks with "4 hours of haemodialysis" three times per week for one month (the run-in period). Then all patients were randomised to receive each of the four noted treatments (below), for six weeks each, in a random order. There was no wash out period between each of the four treatment periods. The intention was that all patients would receive each of the four treatments. Total study time was 24 weeks, plus the 4 week run-in.
1. Standard haemodialysis: four hours of haemodialysis three times per week - haemodialysis was undertaken using a high flux, high efficiency polysulfone dialyser (i.e., F80A dialyser [Fresenius, Inc, Walnut Creek, CA] or equivalent), with a blood flow of 350 - 400 ml/min and a dialysate flow of 500 ml/min
2. Increased dialysate flow: patients received standard dialysis for four hours three times per week but the dialysate flow rate was 800 ml/min rather than 500 ml/min
3. Increased dialysis time: haemodialysis for 4.5 hours, three times per week
4. Double dialyser: patients received haemodialysis for four hours three times per week with two F80A dialysers connected by a Y-connector in a parallel configuration during each run using the method described by Powers et al. Dialysate flow was 800 ml/min

Primary outcome measure
'End-Stage Renal Disease (ESRD) symptoms' domain of the Kidney Disease Quality of Life Short Form (KDQOL-SF) measured at the end of each 6-week treatment session.
Secondary outcome measures
1. Health Utility Index mark 2 (HUI 2) utility score, evaluated during the last week of the treatment (i.e. during week 6 of each treatment period)
2. Exploratory measures of Health-Related Quality Of Life (HRQOL): other domains of the Kidney Disease Quality of Life (KDQOL) and 36-item Short Form health survey (SF-36), evaluated during the last week of the treatment (i.e. during week 6 of each treatment period)
