Abstract
The emergence of multiresistant bacterial strains as agents of healthcare-related infection in hospitals has prompted a review of the control techniques, with an added emphasis on preventive measures, namely good clinical practices, antimicrobial stewardship, and appropriate environmental cleaning. The latter item is about the choice of an appropriate disinfectant as a critical role due to the difficulties often encountered in obtaining a complete eradication of environmental contaminations and reservoirs of pathogens. The present review is focused on the effectiveness of hydrogen peroxide vapor, among the new environmental disinfectants that have been adopted. The method is based on a critical review of the available literature on this topic
Highlights
The disinfection of hospital surfaces is a complex operation aimed at reducing the pathogenic microorganism load
The aim of this review is to evaluate the main studies performed on Hydrogen peroxide in the vaporized form (HPV) activity for multidrug-resistant bacteria (MDR)
This study demonstrated the effectiveness of HPV on porous surfaces a result that was not always guaranteed by disinfectants [28]
Summary
The disinfection of hospital surfaces is a complex operation aimed at reducing the pathogenic microorganism load. The aim of this review is to evaluate the main studies performed on HPV activity for MDR prevention in vitro and in hospital settings [21]. Further studies [26,27] evaluated the HPV disinfection activity under similar conditions to those of the hospital environment, by using experimental technologies for environmental decontamination through aerosolization. Starting from data obtained from a previous study (Boyce), which highlighted the ability of HPV in spores’ inactivation of a wide range of Clostridium difficile strains present on metal disks, the Hospital Saint-Antoine group [37] tested the in vitro activity of 30% HPV. A similar work was carried out in 2005 by an American group [38], who tested the activity of HPV on different Bacillus spp. spores.
