Patient-care items can serve as a source or reservoir for healthcare associated pathogens in hospitals. We reviewed healthcare-associated outbreaks from medical equipment and provided infection prevention recommendations. Multiple healthcare-associated outbreaks via a contaminated patient-care item were identified, including infections with multidrug-resistant organisms. The type of patient-care items implicated as a fomite causing healthcare-associated infections (HAI) has changed over time. Patient populations at risk were most commonly critically ill patients in adult and neonatal ICUs...

Worldwide, millions of patients are affected annually by healthcare-associated infection (HCAI), impacting up to 80,000 patients in European Hospitals on any given day. This represents not only public health risk, but also an economic burden. Complementing routine hand hygiene practices, cleaning and disinfection, antimicrobial coatings hold promise based, in essence, on the application of materials and chemicals with persistent bactericidal or -static properties onto surfaces or in textiles used in healthcare environments...

The emergence of bacterial resistance to carbapenem antibiotics is an urgent public health threat. Carbapenem drugs are a last resort treatment option for life-threatening infections. The frequent use of broad-spectrum antibiotics to treat hospitalized patients provides significant selection pressure favoring the emergence and dissemination of resistant organisms, including carbapenem-resistant Enterobacteriaceae (CRE). CREs have been reported in animal populations, but only rarely in horses. Our objective was to determine the prevalence of CRE in the environment of a referral equine specialty hospital...

We conducted a study using a face-to-face survey to assess knowledge, attitudes, and practices of environmental service workers (ESWs) concerning routine cleaning and disinfection at 3 tertiary hospitals in China. There were 115 (89.1%) respondents who agreed that environmental cleaning can contribute to keep patients safe, whereas 63 (48.8%) reported they were very willing to make cleaning practices better. Only 15 (11.6%) ESWs agreed they were in risk of nosocomial infections during daily cleaning. Our findings suggest that the level of ESWs' knowledge regarding cleaning practices was passable, but the awareness of occupational safety and health was weak...

Ultrasound equipment used in trans-abdominal (TA) and trans-vaginal (TV) examination may carry bacterial contamination and pose risks to infection control during ultrasound examination. We aimed to describe the prevalence of bacterial contamination on ultrasound probes, gel, machine keyboard and cords and examined the effectiveness of low- and high-level disinfection techniques. This study was performed at a public hospital and a private practice. A total of 171 swabs were analyzed and bacterial species were identified using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) analysis and polymerase chain reaction (PCR)...

Luisa Morales, César Rodríguez, María Del Mar Gamboa-Coronado
BACKGROUND: Hospital transmission of Clostridium difficile is fostered by contamination of surfaces and medical equipment with spores highly resistant to disinfectants and regular cleaning procedures. Despite the outbreaks and fatalities that C difficile causes, its epidemiology has not been studied in hospitals from middle- and low-income countries. To tackle this knowledge gap, the detection frequency of C difficile DNA on inert surfaces of a major Costa Rican hospital during and after an outbreak was compared...

BACKGROUND: The focus of nursing home infection control procedures has been on decreasing transmission between healthcare workers and residents. Less evidence is available regarding whether decontamination of high-touch environmental surfaces impacts infection rates or resident outcomes. The purpose of this study was to examine if ultraviolet disinfection is associated with changes in: 1) microbial counts and adenosine triphosphate counts on high-touch surfaces; and 2) facility wide nursing home acquired infection rates, and infection-related hospitalization...

BACKGROUND: Microorganisms can intraluminally access a central venous catheter via the catheter hub. The catheter hub should be appropriately disinfected to prevent central line-associated bloodstream infections (CLABSIs). However, compliance with the time-consuming manual disinfection process is low. An alternative is the use of an antiseptic barrier cap, which cleans the catheter hub by continuous passive disinfection. OBJECTIVE: To compare the effects of antiseptic barrier cap use and manual disinfection on the incidence of CLABSIs...

Environmental disinfection has become the new frontier in the ongoing battle to reduce the risk of health care-associated infections. Evidence demonstrating the persistent contamination of environmental surfaces despite traditional cleaning and disinfection methods has led to the widespread acceptance that there is both a need for reassessing traditional cleaning protocols and for using secondary disinfection technologies. Ultraviolet-C (UV-C) disinfection is one type of no-touch technology shown to be a successful adjunct to manual cleaning in reducing environmental bioburden...
