Efficacy and Safety of Local Application of Chlorhexidine Gluconate Versus Mupirocin Ointment in the Prevention of Peritoneal Dialysis-Related Infection: A Double-Blind, Stratified Randomized Controlled Trial

Peritoneal dialysis (PD) is one of renal replacement therapy used for end-stage renal disease. Since 2011, there has been increasing numbers of patients under "PD First" policy of the Thai government. The most common PD related complication is PD-related infection categorized PD-related peritonitis, and exit site and tunnel infection. Although possible to treat PD-related infection, the incidence of technical failure and death due to peritonitis are still high in Thailand. PD-related infections mainly caused by Staphylococcus aureus. To prevent PD-related infection, cleaning with aseptic solvents using aseptic technique and prevent infection by prescribing prophylactic antibiotics are recommended. The International Society for Peritoneal Dialysis (ISPD) has recommended position statement of the regular use of mupirocin ointment around the catheter exits point and apply in nasal cavity. However, there is rising concern of long term use of mupirocin for mupirocin resistance of S. aureus. CHG is antiseptic use in clinical practice. It can coat at least 12 hours on skin and has anti-bacterial covered in both grams negative and positive. Several meta-analysis studies showed effectiveness of CHG in the prevention of hospitals infection i.e. reduces catheter-related sepsis, postoperative infection, and microbial resistance. According to PD-related infection, CHG has very little evidence of its effectiveness. This pilot study aims to evaluate effectiveness, safety, and cost-utility of CHG-soaked cloths compares to mupirocin ointment and exit site usual care (normal saline and povidone-iodine) with aseptic technique in prevention of PD-related infections. It is a multicenter, double-blind, stratified randomized controlled trial. Participants will be randomized to three arms mupirocin, usual care, or CHG-soaked cloths. They will be followed up 24 months or completetion of PD. The primary outcome is PD-related infection (PD-related peritonitis or exit-site and tunnel infection). Secondary outcomes are infection-related catheter removal and technique failure, nasal and exit-site Staphylococcus aureus colonization, health-related quality of life, mental health, medication adherence, safety, adverse events related to treatments such as skin irritation, rash, etc. For cost-utility analysis, costs include providers and patients expenses. The Utility is assessed using EQ-5D-5L.
