BACKGROUND: Infection control is critical to providing high-quality patient care. Many veterinary teaching hospitals (VTHs) utilize footbaths or footmats at entrances and key control points throughout the facility to decrease trafficking of pathogenic microorganism on contaminated footwear. HYPOTHESIS/OBJECTIVES: To compare efficacy of 4 disinfectants used in footmats for decreasing bacterial contamination of footwear in a large animal hospital. ANIMALS: A single adult dairy cow was housed in a stall for 4 days to facilitate stall contamination with fecal material...

OBJECTIVE To evaluate the impact of no-touch terminal room no-touch disinfection using ultraviolet wavelength C germicidal irradiation (UVGI) on C. difficile infection (CDI) rates on inpatient units with persistently high rates of CDI despite infection control measures. DESIGN Interrupted time-series analysis with a comparison arm. SETTING 3 adult hematology-oncology units in a large, tertiary-care hospital. METHODS We conducted a 12-month prospective valuation of UVGI. Rooms of patients with CDI or on contact precautions were targeted for UVGI upon discharge using an electronic patient flow system...

In this study, we used an online survey to assess knowledge, attitudes, and practices related to environmental cleaning and other infection prevention strategies among environmental services workers (ESWs) at 5 hospitals. Our findings suggest that ESWs could benefit from additional education and feedback as well as new strategies to address workflow challenges. Infect Control Hosp Epidemiol 2016;1-4.

BACKGROUND: Infants admitted to the neonatal intensive care unit (NICU) are more susceptible to infections due to immature immune systems or invasive procedures that compromise protection from bacteria. These infants may stay in the NICU for extended periods of time, are exposed to many caregivers, and may be exposed to other infections. Cell phone use by both family and staff introduce unwanted bacteria into the NICU environment, thereby becoming a threat to this high-risk population...

BACKGROUND: Washbasin U-bends are reservoirs of microbial contamination in healthcare environments. U-Bends are constantly full of water and harbour microbial biofilm. AIM: To develop an effective automated cleaning and disinfection system for U-bends using two solutions generated by electrochemical activation of brine including the disinfectant anolyte (predominantly hypochlorous acid) and catholyte (predominantly sodium hydroxide) with detergent properties. METHODS: Initially three washbasin U-bends were manually filled with catholyte followed by anolyte for 5min each once weekly for five weeks...

OBJECTIVE: To investigate an outbreak of extended-spectrum beta-lactamase (ESBL) producing Enterobacter cloacae that occurred in the Hematology ward (24-bed unit) of the François Mitterrand University Hospital (Dijon, France) between January 2011 and December 2013. The outbreak involved 43 patients (10 infected and 33 colonized). DESIGN: We performed environmental analysis to detect multiresistant E. cloacae for comparison with clinical isolates (genotyping by pulsed-field gel electrophoresis and MLST as well as ESBL-typing) and determined the MICs of the quaternary ammonium compounds (QACs) alkyldimethylbenzylammonium chloride (ADBAC) and didecyldimethylammonium chloride (DDAC)...

In April 2014, pulmonary Pseudomonas aeruginosa and Stenotrophomonas maltophilia co-infections potentially related to bronchoscopic procedures were identified in the intensive care units of a university hospital in Lyon, France. A retrospective cohort of 157 patients exposed to bronchoscopes from 1 December 2013 to 17 June 2014 was analysed. Environmental samples of suspected endoscopes were cultured. Bronchoscope disinfection was reviewed. Ten cases of pulmonary P. aeruginosa/S. maltophilia co-infections were identified, including two patients with secondary pneumonia...

OBJECTIVE: to characterize the moments when there is a need for hand hygiene (HH) by employees who work in Material and Sterilization Center (MSC). METHOD: we conducted a descriptive cross-sectional study in the MSC of a large hospital, from July to November 2012, in Goiânia, state of Goiás, Brazil. Data obtained through observation of workers, following a previously evaluated and tested checklist. RESULTS: to the dirty area, standardized moments of HH were enough...

Hand hygiene, cleaning and disinfection are pre-requirements for hygiene management in hospital settings and the food industry. In order to facilitate risk management, different contamination scenarios and interventions need to be evaluated. In the present study data on transfer rates and reductions of Staphylococcus aureus were provided in an experimental set-up using artificial skin. Using this methodology, test persons were not exposed with pathogenic bacteria. An exposure assessment model was developed and applied to evaluate different contamination routes and hygiene interventions...

PURPOSE OF REVIEW: This article reviews 'no touch' methods for disinfection of the contaminated surface environment of hospitalized patients' rooms. The focus is on studies that assessed the effectiveness of ultraviolet (UV) light devices, hydrogen peroxide systems, and self-disinfecting surfaces to reduce healthcare-associated infections (HAIs). RECENT FINDINGS: The contaminated surface environment in hospitals plays an important role in the transmission of several key nosocomial pathogens including methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus spp...

BACKGROUND: Extensively drug-resistant Acinetobacter baumannii (XDRAB) is a great threat in intensive care units (ICUs). The aim of this study was to describe an XDRAB outbreak which was cross-transmitted in the ICU and respiratory intensive care unit (RICU) in a tertiary care hospital from January-March 2013. METHODS: Patient and environmental surveillances were performed. Isolates were tested for antimicrobial susceptibility. Genotypes were analyzed by multilocus sequence typing (MLST)...

In 2010, 81 confirmed cases of Salmonella Typhimurium DT8 were reported across England and Northern Ireland - an increase of 26% from 2009 and 41% since 2008. Five cases were hospitalized and one death reported, with a strong association found between cases and the consumption of duck eggs. Once present on farms, Salmonella may become persistent and can survive for long periods of time in residual organic matter, increasing risk of infection for follow-on flocks if cleaning and disinfection is not carried out effectively...

BACKGROUND: Cleaning, disinfection, and sterilization (CDS) of medical devices are intended to help prevent health care-associated infections (HAIs), a significant cause of mortality and morbidity. In February 2013 the Johns Hopkins Health System (JHHS; Baltimore) formed a clinical community of experts and stakeholders--physicians, nurses, administrators, infection control practitioners, risk managers, and regulatory staff--to assess CDS practices across facilities. METHODS: A survey administered to leadership indicated endoscopy areas of risk...

BACKGROUND: The main objective of hospital hygiene and infection prevention is to protect patients from preventable nosocomial infections. It was recently stated that the proper goal should be for zero infection rates in sterile surgical procedures. In this article, we attempt to determine whether this demand is supported by the available literature. METHODS: We systematically searched the Medline and EMBASE databases for studies published in the last 10 years on the efficacy of infection control measures and carried out a meta-analysis according to the PRISMA tool...

BACKGROUND: Dry hospital environments are contaminated with pathogenic bacteria in biofilms, which suggests that current cleaning practices and disinfectants are failing. AIM: To test the efficacy of sodium hypochlorite solution against Staphylococcus aureus dry-surface biofilms. METHODS: The Centers for Disease Control and Prevention Biofilm Reactor was adapted to create a dry-surface biofilm, containing 1.36 × 10(7)S. aureus/coupon, by alternating cycles of growth and dehydration over 12 days...
