We present our experience controlling outbreaks of extended-spectrum beta-lactamase (ESBL)-producing bacteria in catheter-associated urinary tract infection and our measures for preventing recurrence of outbreaks. In June 2015, 9 out of 44 hospitalized patients in the same ward had positive urine culture with antibiotic-resistant bacteria, including ESBL-producing Klebsiella pneumoniae belonging to the same cluster, indicating a localized outbreak. The environmental tests detected resistant strains at 1,000 colony forming units/cm2 or more in 8 out of 10 tests...

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 (8) 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 FDA offered double-HLD as a possible response to address this concern. As a result, Providence Health & Services adopted double-HLD as standard procedure for DLE, but no rigorous clinical studies supported this practice. We undertook a quality improvement (QI) study to compare single-HLD versus double-HLD at 4 of our 34 hospitals...

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...

BACKGROUND: Traditionally, Clostridium difficile has been considered a typical healthcare-associated pathogen - transmitted within healthcare facilities and thus prevented by implementation of standard infection control measures. More recently, this concept has been challenged by studies suggesting a relevant role for community-acquisition of C. difficile. AIMS: To discusses the current literature, compiled during the last decade, reporting on sources of acquisition of C...

BACKGROUND: Outbreaks of infection associated with microbial biofilm in hospital hand washbasin U-bends are increasingly being reported. In a previous study the efficacy of a prototype automated U-bend decontamination method was demonstrated for a single non-hospital pattern washbasin. It used two electrochemically-activated solutions generated from brine; a catholyte with detergent properties and anolyte with disinfectant properties. AIM: To develop and test a large-scale automated ECA-treatment system to simultaneously decontaminate 10 hospital pattern washbasin U-bends in a busy hospital clinic...

BACKGROUND: Traditional medical device procurement criteria include efficacy and safety, ease of use and handling, and procurement costs. However, little information is available about life cycle environmental impacts of the production, use, and disposal of medical devices, or about costs incurred after purchase. Reusable and disposable laryngoscopes are of current interest to anesthesiologists. Facing mounting pressure to quickly meet or exceed conflicting infection prevention guidelines and oversight body recommendations, many institutions may be electively switching to single-use disposable (SUD) rigid laryngoscopes or overcleaning reusables, potentially increasing both costs and waste generation...

Recent studies suggest that floors may be an underappreciated source for transmission of health care-associated pathogens. However, there are limited data on the effectiveness of current cleaning and disinfection methods in reducing floor contamination. We demonstrated that manual postdischarge cleaning by environmental services personnel significantly reduced floor contamination, and an automated ultraviolet C room disinfection device was effective as an adjunct to manual cleaning.

Antimicrobial spray products are used by millions of people around the world for cleaning and disinfection of commonly touched surfaces. Influenza A is a pathogen of major concern, leading to up to 49,000 deaths and 114,000 hospitalizations per year in the United States alone. One of the recognized routes of transmission for influenza A is by transfer of viruses from surfaces to hands and subsequently to mucous membranes. Therefore, routine cleaning and disinfection of surfaces is an important part of the environmental management of influenza A...

It is highly difficult to perform safe surgery without sterile instruments, yet the capacity to adequately clean, disinfect and sterilise surgical instruments in low-income and middle-income countries is largely unknown. Sterile Processing Education Charitable Trust developed an assessment tool and, in partnership with Mercy Ships, evaluated the sterile processing capacity in 59 facilities in Madagascar, Benin and the Republic of Congo. This data-driven analysis paper illustrates how lack of sterile processing capacity acts as a barrier to safe surgical care...

Healthcare-acquired infections (HAI) impact on patient care and have cost implications for the Australian healthcare system. The management of HAI is exacerbated by rising rates of antimicrobial resistance (AMR). Health-care workers and a contaminated hospital environment are increasingly implicated in the transmission and persistence of multi-resistant organisms (MRO), as well as other pathogens, such as Clostridium difficile. This has resulted in a timely focus on a range of HAI prevention actions. Core components include antimicrobial stewardship, to reduce overuse and ensure evidence-based antimicrobial use; infection prevention strategies, to control MRO - particularly methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus spp...

Ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs) in hair are effective direct biomarkers of ethanol ingestion, whose analytical determination can be used to discriminate between chronic and occasional ethanol intake. Ethanol is a compound widely used in some workplaces (e.g., clinics, hospitals) and is present in considerable amounts in mouthwash for oral cleaning, medications, cosmetic products, hydro-alcoholic disinfectants and antiseptics for hands. This study examined the ethyl alcohol exposure derived from hand disinfectants (in gel form) by simulating the typical occupational situation of medical-health workers (healthcare workers, nurses, surgeons, etc...

The recent epidemic of Ebola virus disease (EVD) resulted in countries worldwide to prepare for the possibility of having an EVD patient. In this study, we estimate the costs of Ebola preparedness and response borne by the Dutch health system. An activity-based costing method was used, in which the cost of staff time spent in preparedness and response activities was calculated based on a time-recording system and interviews with key professionals at the healthcare organizations involved. In addition, the organizations provided cost information on patient days of hospitalization, laboratory tests, personal protective equipment (PPE), as well as the additional cleaning and disinfection required...

Background: Despite intensified efforts to reduce hospital-onset Clostridium difficile infection (C. difficile; HO-CDI), its clinical and economic impacts continue to worsen. Many institutions have adopted bundled interventions that vary considerably in composition, strength of evidence, and effectiveness. Considerable gaps remain in our knowledge of intervention effectiveness and disease transmission, which hinders HO-CDI prevention. Methods: We developed an agent-based model of C...
