Room Disinfection

Hydrogen peroxide room disinfection – ready for prime time?

Non-manual techniques for terminal disinfection of hospital rooms have gained increasing interest in recent years as means to reduce transmission of multidrug-resistant organisms (MDROs). A prospective crossover study by Blazejewski and colleagues in five ICUs of a French academic hospital with a high prevalence of MDRO carriers showed that two different hydrogen peroxide (H2O2)-based non-touch...

Ultraviolet in-room air disinfection and recirculation greatly reduces viable airborne particle concentrations in the operating room setting

Objective. To evaluate the effectiveness of a novel in-room air disinfection technology through the use of real-time viable airborne particulate counting. Methods. Using laser particle fluorescence techniques in real time, airborne viable particle concentrations were obtained before and after air treatment with the in-room C-UVC device in an active hospital operating room setting. Results. A la...

Safety of upper-room ultraviolet germicidal air disinfection for room occupants: results from the Tuberculosis Ultraviolet Shelter Study.

OBJECTIVES We evaluated the safety of room occupants in the Tuberculosis Ultraviolet Shelter Study (TUSS), a double-blind, placebo-controlled field trial of upper-room ultraviolet germicidal irradiation (UVGI) at 14 homeless shelters in six U.S. cities from 1997 to 2004. METHODS Data collection involved administering questionnaires regarding eye and skin irritation to a total of 3,611 staff a...

Efficacy, efficiency and safety aspects of hydrogen peroxide vapour and aerosolized hydrogen peroxide room disinfection systems.

BACKGROUND This was a head-to-head comparison of two hydrogen-peroxide-based room decontamination systems. AIM To compare the efficacy, efficiency and safety of hydrogen peroxide vapour (HPV; Clarus R, Bioquell, Andover, U.K.) and aerosolized hydrogen peroxide (aHP; SR2, Sterinis, now supplied as Glosair, Advanced Sterilization Products (ASP), Johnson & Johnson Medical Ltd, Wokingham, U.K.) r...
