Clinical Trial Summary
Exit site infection (ESI) is one of the major predisposing factors to peritoneal dialysis
(PD) related peritonitis. Chlorhexidine Gluconate (CHG) has been widely used for cutaneous
disinfection for half a century. TegadermTM CHG is a water-proof dressing with gel pads that
provide 2% CHG to the skin surface and effectively prevents catheter-related infections for
intravascular catheters. However, its use has not been accessed in patients with PD
catheters. We aim to evaluate the effectiveness of TegadermTM CHG dressing in preventing ESI
in PD patients.
Description:
Peritoneal Dialysis (PD) is one of the common therapies for patients with End Stage Renal
Failure (ESRF). As the global burden of chronic kidney disease continues to increase, so does
the need for a cost-effective renal replacement therapy (1). Patient outcomes with peritoneal
dialysis are comparable to or better than those with haemodialysis, and peritoneal dialysis
is also more cost-effective (1). It is reported that PD improves patient's well-being and has
greater personal freedom as compared to Hemodialysis through less restrictive life-style
changes (2). All dialysis treatments include a certain risk of infection because of the
decreased immune defenses of patients in established renal failure (ERF) and because dialysis
techniques increase the potential of microbial contamination (3).
PD is associated with a high risk of infection of the peritoneum, subcutaneous tunnel and
catheter exit site (4). ESI is diagnosed by the presence of purulent drainage, with or
without erythema of the skin at the catheter-epidermal interface (5). Exit site infection
(ESI) increases the possibility of developing PD peritonitis which demands careful attendance
to these problems. It is estimated that 12% of cases of ESI results in PD peritonitis (6). As
many as 15%-50% of ESRF patients are on PD, but recurrent or prolonged peritonitis may causes
technique failure in PD (3). The majority of catheter related problems are of an infection
nature - mainly represented by peritonitis (61%); ESI (23%); catheter obstruction,
dislocation and leakage making up the rest (3). Peritonitis can be associated with severe
pain leading to hospitalisation, catheter loss, and a risk of death; and it therefore
continues to be a serious complication for PD patients (7).
There are no recommendations what topical care of the PD catheter exit site is optimal.
Several methods including Povidone-Iodine, hydrogen peroxide, chlorhexidine, soap and water,
and topical creams such as gentamicin or mupirocin cream have been studied for exit site care
(8,9).
A number of topical cleansing agents have been studied for prevention of catheter-related
infections however no cleansing agent has shown to be superior with respect to preventing
catheter-related infections (5). The International Society for Peritoneal Dialysis (ISPD)
recommends the use of daily topical application of antibiotic cream or ointment to the
catheter exit site to prevent infection and exit site be cleansed at least twice weekly and
every time after a shower (5).
Appropriate care of the exit site will avoid loss of catheter and unnecessary dialysis
modality change. PD-related infection is the most common cause of technique failure.
Prevention and treatment of PD catheter related infection such as peritonitis and exit site
infections are important to maintain on PD therapy.
In Khoo Teck Puat Hospital (KTPH) we had been following the ISPD guidelines on the dressing
recommendation to use iodine as the preferred cleansing agent and application of Gentamicin
cream 0.1% as prophylaxis to prevent PD exit site infection. However, we had noticed an
increase in patient's risk of PD ESI from 2016 0.15/year at risk, 2017 0.19/year at risk and
2018 0.22/year at risk. Of which 40-55% were gram positive infections, 5-15% were gram
negative infections and the rest were having no bacterial cultures or fungal infections. We
evaluated on the infection episodes and reassessed on patients technique and home environment
and found that reasons of infection were due to poor compliance to dressing techniques,
frequency of change after shower, hand washing technique and home environment cleanliness.
Several research articles were reviewed and Chlorhexidine Gluconate (CHG) was found to be
used widely throughout the world for more than 50 years for cutaneous disinfection, hand
hygiene and oral hygiene, and the safety of CHG is well established (10).Clinically relevant
high-level bacterial resistance has been very rare (11).
TegadermTM CHG Dressing had a gel pad that provides 2% CHG to the skin surface. It was proven
to largely reduce catheter-related bloodstream infections (CRBSI) (from 1.21 to 0.28 per 1000
catheter days) and vascular catheter colonization (12). The CHG dressing is recommended to be
worn up to 7days and provide CHG antimicrobial protection, secure adhesion, gentle removal,
site visibility, breathability and patient comfort (13).
Unlike CRBSI, TegadermTM CHG Dressing was not evaluated for its effectiveness in prevention
of exit infection in PD patients. This would be the first study to evaluate the effectiveness
of TegadermTM CHG Dressing in reducing peritoneal dialysis catheter exit site infection. The
ease of application of the dressing will help to increase patients and caregivers' compliance
as the frequency of change was reduced from daily to once every 7 days. TegadermTM CHG
dressing also water-proof and it will helps in maintaining the exit site clean and dry. By
reducing the PD ESI rates, it will also helps in preventing secondary peritonitis and
prevents unnecessary dialysis modality changes.
This would be the first study to evaluate the effectiveness of Tegadermâ„¢ chlorhexidine
gluconate-gel (CHG) dressing for the prevention of exit site infection in patient receiving
peritoneal dialysis.
Participants will use Tegadermâ„¢ chlorhexidine gluconate-gel (CHG) dressing for a period of
4-6months. Results will be compared with historical data from 1st Nov 2016 to 31st Oct 2017.
Estimated 40 patient's historical data will be reviewed.
New Method:
Patients are taught to perform 7 steps handwashing, clean PD exit site with chlorhexidine
swab sticks, dry with gauze, and apply TegadermTM CHG Dressing. This has to be repeated every
7days or when the dressing is soiled.
Old Method:
Patients are taught to perform 7 steps handwashing, clean PD exit site with 3 swab sticks,
dry with gauze, apply Gentamicin cream 0.1% and cover with soft cloth dressing. This has to
be repeated daily after shower or when the dressing is soiled.
