Chlorhexidine Caps for CLABSI Prevention in Hemodialysis: a Pilot Randomized Controlled Trial

The goal of this clinical trial is to compare a chlorhexidine antimicrobial barrier cap in patients requiring hemodialysis treatment to the standard hemodialysis caps currently used within the Metro North Kidney Health Service. The main questions to answer are: * Study Feasibility * Occurrence of infectious complications related to renal central venous catheters Participants will be randomly allocated to receive either of the below hemodialysis caps to cover their hemodialysis catheter hub: * The standard hemodialysis cap used at the Royal Brisbane and Women's Hospital, or * The intervention hemodialysis cap containing chlorhexidine inside it Researchers will compare standard and chlorhexidine hemodialysis caps to see if the presence of chlorhexidine improves the occurrance of infectious complications related to the hemodialysis catheter.
