An effective and automated approach for reducing infection risk from contaminated privacy curtains

Area of Science:

• Infection Control and Hospital Epidemiology
• Environmental Hygiene
• Antimicrobial Resistance

Background:

• Privacy curtains are significant reservoirs for multidrug-resistant organisms (MDROs) in healthcare settings.
• Existing methods for reducing curtain contamination and infection transmission risks are limited.
• Healthcare-associated infections (HAIs) pose a substantial burden on patient safety and healthcare systems.

Purpose of the Study:

• To evaluate the efficacy of continuous dry hydrogen peroxide (DHP) in reducing microbial contamination on privacy curtains.
• To assess the sustainability of DHP's antimicrobial effect over a 28-day period.
• To provide evidence for improved infection control strategies in tertiary care hospitals.

Main Methods:

• A prospective study was conducted across five units in a tertiary care hospital.
• Continuous dry hydrogen peroxide (DHP) disinfection was implemented for privacy curtains.
• Microbial sampling and analysis were performed to quantify bacterial load before and after DHP application.

Main Results:

• Continuous DHP application achieved a 99.47% reduction in microbial load on Day 1.
• Statistically significant reductions in microbial contamination were sustained throughout the 28-day study period.
• The DHP method demonstrated broad-spectrum antimicrobial activity against common hospital pathogens.

Conclusions:

• Continuous dry hydrogen peroxide (DHP) is a highly effective method for reducing privacy curtain contamination.
• DHP offers a sustainable and viable solution for enhancing environmental hygiene and reducing infection transmission risks.
• This intervention has the potential to significantly improve patient safety in healthcare facilities.
