Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
3 mL intravenous 70% ethanol is instilled into each lumen of the tunnelled intravenous catheter as a lock, at the end of the haemodialysis treatment, once weekly. The ethanol is withdrawn before the next dialysis session, 48 hours later. The patient remains on the study until the catheter is removed.
Intervention code [1] 236731 0
Treatment: Drugs
Comparator / control treatment
Three times weekly, as per usual practice, Heparin (5000 units per mL) is instilled into each lumen of the tunnelled intravenous catheter as a lock (volume as per lumen instructions - this amount is variable depending on the brand of catheter/size of lumen), at the end of the haemodialysis treatment and withdrawn before the next dialysis session, 48 hours later. The patient remains on the study until the catheter is removed.
Control group
Active

Outcomes
Primary outcome [1] 238113 0
Time to catheter removal, due to sepsis, bacteraemia or if it is no longer needed.
Timepoint [1] 238113 0
Following randomisation and weekly Ethanol treatment, the time to catheter removal is monitored continuously.
Secondary outcome [1] 242326 0
Time to the first episode of catheter-related bacteraemia. This is assessed by medical examination and blood culture results.
Timepoint [1] 242326 0
Following randomisation and weekly Ethanol / Heparin treatment, time to the first episode of catheter-related bacteraemia is monitored continuously until the catheter is removed.
Secondary outcome [2] 242447 0
Incidence of catheter-related bacteraemia caused by different pathogens.
Timepoint [2] 242447 0
Blood cultures will be taken if clinically indicated as assessed by medical staff.
Secondary outcome [3] 242463 0
Time to infection-related catheter removal
Timepoint [3] 242463 0
Assessed by medical examination and blood culture results, necessitating catheter removal.
Secondary outcome [4] 242464 0
Adverse reactions such as problems with dialysis flow, lumen and dialysis clotting.
Timepoint [4] 242464 0
Assessed by medical and nursing staff at each dialysis session by examination. A trial safety committee is set up to allow external evaluation of catheter-related problems at 6 months and annually after that period.
Secondary outcome [5] 242465 0
Time to exit site infection
Timepoint [5] 242465 0
Assessed by medical and nursing staff at each dialysis session and microbiological results of exit site wound swabs.
Secondary outcome [6] 242471 0
Quality of life
Timepoint [6] 242471 0
Patients will be assessed for Quality of Life, using the EQ-5D questionnaire, on a monthly basis.
Secondary outcome [7] 242474 0
Economic cost
Timepoint [7] 242474 0
Hospital-associated costs (length of stay of hospital admissions, pharmacy costs, laboratory/radiology costs) plus other healthcare service costs (General Practitioner (GP) visits)

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects are identified, recruited, consented and randomised by study staff. Stratification will occur for Incident versus Prevelent catheters. Central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Allocation concealment is assured using a centralised computer-generated block randomisation procedure.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Outcome assessment based on standardised and objective criteria will be performed blinded to treatment allocation.
