A randomized control trial evaluating efficacy of antimicrobial impregnated hospital privacy curtains in an intensive...

Area of Science:

• Healthcare-associated infections
• Infection control
• Environmental hygiene

Background:

• Healthcare settings are vulnerable to pathogen transmission from previous occupants.
• Hospital privacy curtains are frequently contaminated with pathogenic bacteria.
• Antimicrobial-impregnated curtains offer a potential strategy to mitigate this contamination risk.

Purpose of the Study:

• To evaluate the efficacy of antimicrobial-impregnated curtains in reducing pathogenic bacterial contamination in intensive care unit (ICU) rooms.
• To assess the impact of supplementary hypochlorite spray on antimicrobial curtain effectiveness.

Main Methods:

• Intensive care unit rooms were randomized into three groups: standard curtains (SC), BioSmart curtains (BSC), and BSC with twice-weekly hypochlorite spray (BSC-pre and BSC-post).
• Pathogenic bacterial contamination was assessed through sample collection twice weekly for three weeks.
• Statistical analysis was performed to compare contamination levels between the groups.

Main Results:

• The likelihood of remaining uncontaminated was 38% for SC, 37% for BSC, and 60% for BSC-pre.
• No statistically significant difference in pathogenic contamination was found between SC, BSC, and BSC-pre groups (P=0.1921).
• Hypochlorite spray provided transient decontamination, with effects diminishing within 72 hours.

Conclusions:

• BioSmart curtains did not demonstrate a significant reduction in pathogenic contamination compared to standard curtains.
• Antimicrobial curtains show potential for reducing environmental contamination in healthcare settings.
• Further research is necessary to determine the long-term efficacy and impact of antimicrobial curtains in healthcare environments.
