Scientific titleA multicentre randomised trial comparing the effects of 2% chlorhexidine gluconate in 70% isopropyl alcohol as a skin, exit site and catheter hub cleansing agent versus other forms of chlorhexidine gluconate which are in routine use, on central venous catheter-related infections in haemodialysis patients
Study acronymCHG Trial
Study objectivesThere is no difference between 2% chlorhexidine gluconate in 70% alcohol and 0.05% aqueous chlorhexidine gluconate or 0.5% chlorhexidine gluconate in 70% alcohol in the reduction of central venous catheter (CVC) related infections in haemodialysis patients.

Please note that as of 21/01/2013, the following changes were made to the trial record:
1. The anticipated start date was updated from 01/09/2010 to 18/10/2010
2. The anticipated end date was updated from 05/09/2012 to 14/09/2012
Ethics approval(s)Ethical Approval was granted by the Joint St. James Hospital and Adelaide and Meath Hospital, incorporating The National Children's Hospital Research Ethics Committee, on the 12th of July 2010 (ref: 2010/27/03)
Health condition(s) or problem(s) studiedEnd stage renal disease; haemodialysis; central venous catheter infections
InterventionAll patients assigned to the 'experimental' group will receive 2% chlorhexidine gluconate in 70% alcohol cutaneous solution. Those patients assigned to the 'control' group will receive the chlorhexidine gluconate cutaneous solution that is the standard antiseptic agent used in the routine care of their CVC. There are two different types of routine care in use in the centres that will participate in the randomised trial: 0.5% chlorhexidine gluconate in 70% alcohol and 0.05% aqueous chlorhexidine gluconate. Patients whose routine care is 0.5% chlorhexidine gluconate in 70% alcohol will be randomised to receive either the experimental intervention of 2% chlorhexidine gluconate in 70% alcohol or the routine care of 0.5% chlorhexidine gluconate in 70% alcohol. Similarly, patients whose routine care is 0.05% aqueous chlorhexidine gluconate will be randomised to receive either the experimental intervention of 2% chlorhexidine gluconate in 70% alcohol or routine care of 0.05% aqueous chlorhexidine gluconate.

1. The experimental group will receive 2% chlorhexidine gluconate in 70% alcohol antiseptic cleansing agents in the form of:
1.1. ChloraPrep® with Tint 2% w/v/70%v/v cutaneous solution (3ml applicator) will be used to cleanse the skin and exit site of the central venous catheter when the catheter dressing is changed.
Duration of treatment: Subjects will receive this intervention every time the dressing is changed for a period of 12 months. Frequency of dressing change will be determined by local policy.
1.2. Sani Cloth CHG 2% medical device wipe will be used to cleanse the hubs of central venous catheters when connecting or disconnecting patients from dialysis.
Duration of treatment: every dialysis session (three times a week) for a period of 12 months

2. Patients allocated to the 'control' group will receive either:
2.1. 0.5% chlorhexidine gluconate in 70% alcohol cutaneous solution (Hydrex Pink) or
2.2. 0.05% aqueous chlorhexidine gluconate cutaneous solution (Unisept)
Duration of treatment will be 12 months. Control intervention will be used to cleanse the catheter hubs when connecting and disconnecting patients from dialysis (three times a week) for a period of 12 months. Control intervention will also be used when skin and exit site are cleansed every time the catheter dressing is changed for a period of 12 months. Frequency of dressing change will be determined by local policy.

Recruitment will take place over an eight month period. Each patient will be followed up for 12 months. Data capture will be completed in 20 months from the recruitment of the first patient. Patients who develop CVC-associated or related bloodstream infection will be withdrawn from the study.

Case definitions used in the trial protocol will be those set down by the Infectious Disease Society of America and the Centre for Disease Control and Disease.
Secondary outcome measures1. Time to development of first CVC-related infection
2. Patient mortality secondary to infection
3. CVC-related infection rates according to causative organism
4. Time to infection associated catheter removal
5. Episodes of hospitalisation
6. Incidence of adverse reactions
7. Economic Cost
8. Incidence and prevalence of arteriovenous fistula (AVF), arteriovenous graft (AVG) and CVC use in haemodialysis population
