What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if an antiseptic body wash and nasal ointment can reduce the risk of infections at surgical sites after hospital discharge. Participants will use either a special antiseptic soap and antibiotic nasal ointment or a regular soap and placebo ointment. The study targets individuals who have recently undergone open colon or small bowel surgery and can care for themselves or have assistance with bathing. As a Phase 4 trial, this research seeks to understand how an already FDA-approved and effective treatment can benefit more patients.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you have an active infection requiring systemic antibacterial agents, you may be excluded from participating.

What is the safety track record for 2% Mupirocin and 4% Chlorhexidine Gluconate?

Research has shown that using a nasal antibiotic ointment called mupirocin with an antiseptic soap called chlorhexidine gluconate is generally safe for patients. Studies confirm that this combination effectively reduces infections at surgical sites. Mupirocin is safe when applied inside the nose twice a day for five days, and chlorhexidine is well-tolerated when used on the skin.

Some people might experience mild skin irritation or a burning sensation from these treatments, but serious side effects are rare. Hospitals often use this combination to prevent infections after surgery. It helps kill bacteria that can cause infections, making it a valuable tool for keeping surgical sites clean and reducing the risk of complications. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about this trial because it explores a promising approach to reducing surgical site infections through antiseptic decolonization. Unlike typical methods that rely on standard soap and regular nasal ointments, this trial combines a chlorhexidine body wash with nasal mupirocin, an antibiotic ointment. This combination targets harmful bacteria more effectively, potentially lowering infection rates and improving surgical outcomes. By addressing bacteria both on the skin and in the nasal passages, this approach could offer a more comprehensive infection prevention strategy than current standard care options.

What evidence suggests that this trial's treatments could be effective for reducing surgical site infections?

Research shows that using a chlorhexidine body wash and nasal mupirocin can help reduce infections after surgery. In this trial, participants in the Decolonization arm will use this combination. A review of several studies has found that cleaning the skin with chlorhexidine before surgery results in fewer infections compared to other methods. Studies also indicate that chlorhexidine lowers infection rates in various surgeries, including those with a higher risk of contamination. When used together, mupirocin and chlorhexidine further reduce infections in surgical patients. Moderate-quality evidence supports this combination for preventing infections after surgery. Participants in the Routine Care arm will use soap without antiseptic properties and a placebo nasal ointment. ^{3 6 7 8 9}

Trial Overview

The DECREASE SSI Trial is testing if bathing with chlorhexidine and using nasal mupirocin for 30 days after discharge can reduce infections compared to using regular soap (placebo) and placebo nasal ointment in patients who've undergone certain bowel surgeries.

How Is the Trial Designed?

Group I: Decolonization Active Control 2 Interventions

Participants randomized into this arm will perform decolonization using topical antiseptic soap (chlorhexidine body wash) and an antibiotic ointment (nasal mupirocin).

Group II: Routine Care Placebo Group 2 Interventions

Participants randomized into this arm will perform routine care using soap without antiseptic properties (placebo) and placebo nasal ointment.

Published Research Related to This Trial

Olanexidine gluconate demonstrated superior bactericidal efficacy compared to chlorhexidine and povidone-iodine when applied to blood-contaminated skin, making it a promising option for preoperative skin preparation.

In non-blood-contaminated conditions, olanexidine's effectiveness was comparable to that of established antiseptics, indicating its potential as a reliable antiseptic for surgical use.

In a study of 120 patients undergoing nasal surgery, the use of xylometazoline hydrochloride 0.1% nasal spray did not provide better symptom relief compared to sterile physiological saline aerosol.

Patients using xylometazoline reported significantly higher pain scores post-operatively, suggesting that it may not be a safe or effective option for managing symptoms after nasal surgery.

Nasal decolonization using mupirocin combined with chlorhexidine body wash significantly reduces the incidence of S. aureus-related surgical site infections in patients who are carriers, particularly in various surgical procedures, indicating its efficacy as a targeted intervention.

Universal nasal decolonization is more cost-effective than targeted approaches, potentially saving the healthcare system approximately $45.08 million over five years, while targeted decolonization may increase costs despite its benefits.

Implementing a comprehensive nasal decolonization protocol, which included a nonantibiotic alcohol-based antiseptic and chlorhexidine, significantly reduced surgical site infection rates in spine surgery patients by 81%.

The trial lasted 15 months and showed a decrease in infection rates from 1.76 to 0.33 per 100 surgeries, highlighting the effectiveness of this combined approach in improving patient safety.

Pre-operative decolonization with octenidine (OCT) did not significantly reduce overall surgical site infection (SSI) rates in patients undergoing elective coronary artery bypass graft (CABG) surgery, with rates of 15.4% in the control group and 13.3% in the intervention group.

However, the intervention significantly lowered the rate of harvest site SSIs (2.5% vs 0.5%) and organ/space sternal SSIs (1.9% vs 0.3%), indicating some targeted benefits of OCT in specific infection types.

Nasal decontamination significantly reduces the risk of surgical site infections (SSIs) in Staphylococcus aureus carriers, particularly in patients undergoing pulmonary surgeries, based on a review of 20 randomized controlled trials involving over 10,500 patients.

Chlorhexidine was found to be effective in decreasing SSI rates (RR = 0.474), while mupirocin did not show a significant benefit, indicating that the choice of decontamination method can impact surgical outcomes.

In a study involving 614 patients, mupirocin nasal ointment was highly effective in eradicating Staphylococcus aureus nasal carriage, achieving an eradication rate of 83.5% compared to 27.8% in the placebo group.

Despite the successful eradication of nasal carriage, mupirocin did not significantly reduce the overall rate of surgical site infections (SSIs) or the length of hospital stays, indicating that while it may help with nasal carriage, it does not necessarily prevent SSIs.

Many skin antiseptics used in healthcare settings are sold as nonsterile and can be contaminated with harmful microorganisms, potentially leading to healthcare-associated infections.

There is a need to include skin antiseptics in antibiotic stewardship programs to mitigate the risk of contamination and the development of antimicrobial resistance, especially in hospitalized patients.

In a study of 1989 patients, preoperative washing with chlorhexidine significantly reduced the overall incidence of postoperative wound infections to 9%, compared to 12.8% with bar soap and 11.7% with a placebo.

For 'clean' surgeries, chlorhexidine further decreased the infection rate to 7.2%, and specifically reduced Staphylococcus aureus infections to 3%, highlighting its efficacy in preventing infections compared to traditional washing methods.
