Hospital-acquired legionnaires disease in a university hospital: impact of the copper-silver ionization system.
نویسندگان
چکیده
We evaluated the impact of the copper-silver ionization system in a hospital where hyperendemic nosocomial legionellosis and was present and all previous disinfection measures had failed. After implementation of the copper-silver ionization system, environmental colonization with Legionella species decreased significantly, and the incidence of nosocomial legionellosis decreased dramatically, from 2.45 to 0.18 cases per 1000 patient discharges.

BACKGROUND AND OBJECTIVES Hospital-acquired legionnaires' disease can be prevented by disinfection of hospital water systems. This study assessed the long-term efficacy of copper-silver ionization as a disinfection method in controlling Legionella in hospital water systems and reducing the incidence of hospital-acquired legionnaires' disease. A standardized, evidence-based approach to assist ho...

متن کاملLegionella control by chlorine dioxide in hospital water systems
egionnaires’ disease is caused by Legionella bacteria, which colonize 12–70% of hospital water systems (Lin et al, 1998b). Of the Legionnaires’ disease cases reported to the Centers for Disease Control and Prevention (CDC), 25–45% were hospital-acquired (Benin et al, 2002). Legionella and other opportunistic pathogens colonize water systems; cause pneumonia, wound, and bloodstream infections in...
متن کاملPrevention of hospital-acquired legionellosis.
PURPOSE OF REVIEW The incidence of hospital-acquired legionellosis appears to be increasing. Presence of Legionella in the hospital drinking water is the only risk factor known with certainty to be predictive of risk for contracting Legionnaires' disease. RECENT FINDINGS Given the high frequency of infection by nonpneumophila and nonserogroup 1 species, both Legionella respiratory culture on ...
متن کاملIntermittent use of copper-silver ionization for Legionella control in water distribution systems: a potential option in buildings housing individuals at low risk of infection.
One copper-silver ionization system was sequentially installed onto the hot-water recirculation lines of two hospital buildings colonized with Legionella pneumophila, serogroup 1. A third building with the same water supply and also colonized with Legionella served as a control. Four weeks after activation of the system, distal site positivity for Legionella in the first test building dropped t...
