Study design	Randomised double blind controlled trial
Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	Not specified
Study type	Prevention
Scientific title
Study objectives	The null hypothesis to be tested is that antibiotic line locks will not reduce the incidence of catheter related blood stream infection compared with the standard practice of catheter filling with heparin alone.
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Haemodialysis catheter related sepsis
Intervention	Control group will receive usual heparin line locks between dialysis sessions. Intervention group will receive a line lock containing heparin, vancomycin and gentamicin.
Intervention type	Other
Primary outcome measure	The time in days from insertion of tunnelled haemodialysis catheter (THDC) to first catheter related infection (CRI). CRI will be diagnosed by a combination of clinical suspicion, raised temperature, blood tests (white cell count and inflammatory markers) and the results of blood cultures from the tunnelled haemodialysis catheter (THDC) and from a peripheral vein.
Secondary outcome measures	1. Mean haemoglobin concentration 2. Mean erythropoietin dose adjusted for body mass 3. Mean serum albumin concentration 4. Mean number of days in hospital per annum 5. Mean number of hospital admissions per annum
Overall study start date	01/08/2004
Completion date	01/08/2006

Participant type(s)	Patient
Age group	Adult
Sex	Both
Target number of participants	80
Key inclusion criteria	All patients requiring insertion of a tunnelled haemodialysis catheter (THDC) for haemodialysis.
Key exclusion criteria	1. Patients on prolonged courses of antibiotics (oral or parenteral) i.e. for greater than 2 weeks. (This may reduce the incidence of CRI and therefore confound the results). 2. Patients with a known allergy to vancomycin or gentamicin 3. Patients known to suffer from heparin induced thrombocytopenia 4. Patients who are pregnant or plan to become pregnant. (Vancomycin and gentamicin are potentially toxic to the fetus). 5. An inability to provide informed consent to participation in the study
