The Massachusetts General Hospital (MGH) is merging its older endoscope processing facilities into a single new facility that will enable high-level disinfection of endoscopes for both the ORs and Endoscopy Suite, leveraging economies of scale for improved patient care and optimal use of resources. Finalized resource planning was necessary for the merging of facilities to optimize staffing and make final equipment selections to support the nearly 33,000 annual endoscopy cases. To accomplish this, we employed operations management methodologies, analyzing the physical process flow of scopes throughout the existing Endoscopy Suite and ORs and mapping the future state capacity of the new reprocessing facility...

Lysostaphin (Lst) is a potent bacteriolytic enzyme that kills Staphylococcus aureus , a common bacterial pathogen of humans and animals. With high activity against both planktonic cells and biofilms, Lst has the potential to be used in industrial products, such as commercial cleansers, for decontamination. However, Lst is inhibited in the presence of monoethanolamine (MEA), a chemical widely used in cleaning solutions and pharmaceuticals, and the underlying mechanism remains unknown. In this study, we examined the cell binding and killing capabilities of Lst against S...

High mortality and hospitalization rates have seen Listeria monocytogenes as a foodborne pathogen of public health importance for many years and of particular concern for high-risk population groups. Food manufactures face an ongoing challenge in preventing the entry of L. monocytogenes into food production environments (FPEs) due to its ubiquitous nature. In addition to this, the capacity of L. monocytogenes strains to colonize FPEs can lead to repeated identification of L. monocytogenes in FPE surveillance...

BACKGROUND: Manual cleaning and disinfection of the operating room (OR) environment may be inadequate due to human error. No-touch technologies, such as pulsed-xenon ultraviolet light (PX-UV), can be used as an adjunct to manual cleaning processes to reduce surface contamination in the OR. This article reports the cumulative results from 23 hospitals across the United States that performed microbiologic validation of PX-UV disinfection after manual cleaning. METHODS: We obtained samples from 732 high-touch surfaces in 136 ORs at 23 hospitals, after manual terminal cleaning, and again after PX-UV disinfection (n = 1464 surface samples)...

Recognized issues with poor hand hygiene compliance among healthcare workers, and reports of re-contamination of previously chemically disinfected surfaces through hand contact, emphasize need for novel hygiene methods in addition to those currently available. One such approach involves antimicrobial (nano)-coatings (AMC), whereby integrated active ingredients are responsible for elimination of microorganisms that come into contact with treated surfaces. While widely studied under laboratory conditions with promising results, studies under real life healthcare conditions are scarce...

We present our experience with controlling an outbreak of extended-spectrum beta-lactamase (ESBL)-producing bacteria in catheter-associated urinary tract infection and the measures taken to prevent future outbreaks. In June 2015, 9 out of 44 hospitalized patients in the same ward tested positive for antibiotic-resistant bacteria in urine cultures, including ESBL-producing Klebsiella pneumoniae. Since these bacteria belonged to the same cluster, we concluded this was a localized outbreak. Seven out of 10 environmental tests detected resistant strains at 1,000 colony forming units/cm2 or more...

Background: Hospital-acquired infections (HAIs) are infections that patients contract while in the hospital that were neither present nor developing at the time of admission. In Canada an estimated 10% of adults with short-term hospitalization have HAIs. According to 2003 Canadian data, between 4% and 6% of these patients die from these infections. The most common HAIs in Ontario are caused by Clostridium difficile . The standard method of reducing and preventing these infections is decontamination of patient rooms through manual cleaning and disinfection...

BACKGROUND AND AIMS: In a pilot study, we demonstrated that current guidelines for duodenoscope and linear echoendoscope (DLE) reprocessing using a single cycle of high-level disinfection (HLD) in an automated reprocessor may be inadequate. In August 2015, the U.S. Food and Drug Administration offered double HLD as a possible response to address this concern. As a result, Providence Health and Services adopted double HLD as standard procedure for DLEs, but no rigorous clinical studies supported this practice...

Ricky Dippenaar, Johan Smith
BACKGROUND: Expressed human milk (EHM) feed preparation areas represent a potential source of unintentional nosocomial infection. Daily disinfection of environmental surfaces remains an essential intervention to mitigate nosocomial infections. The inefficiency of conventional cleaning and disinfection contributes to an increased risk for the acquisition of multi-drug resistant pathogens. "Non touch" technologies such as the pulsed xenon ultraviolet (PX-UVD) light device have documented sustained reduction in surface bacterial colonization and reduced cross contamination...
