Burden of perianal Staphylococcus aureus colonization in nursing home residents increases transmission to healthcare worker gowns and gloves.
Transmission of Staphylococcus aureus (S. aureus) to health care workers (HCWs) on gowns and gloves has been an issue in nursing homes. This study evaluated the effect of the burden in 13 community-based nursing homes in Maryland and Michigan. Residents were cultured for S. aureus at the perianal skin and the anterior nares areas. A total of 403 residents were enrolled, with 169 colonized with methicillin-resistant S. aureus (MRSA) or methicillin-sensitive S. aureus (MSSA). Transmission to HCW gowns and gloves was greater from those colonized with greater quantities of S. aureus on the perianal skin. These findings inform future infection control practices for both MRSA and MSSA in nursing homes.

High prevalence of multidrug-resistant organism colonization in 28 nursing homes: an "iceberg effect."
The objective of this study was to determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus spp. (VRE), extended-spectrum beta-lactamase producing organisms (ESBLs), and carbapenem-resistant Enterobacteriaceae (CRE) among residents and in the environment of nursing homes (NHs). The investigators concluded that in more than half of the NHs, more than 50% of residents were colonized with MDROs of clinical and public health significance, most commonly MRSA and ESBL. Additionally, the vast majority of resident rooms and common areas were MDRO contaminated.

Chlorhexidine bathing strategies for multidrug-resistant organisms: a summary of recent evidence.
This systematic literature review investigated the latest evidence for patient bathing with a 2%-4% chlorhexidine gluconate solution to reduce multidrug-resistant organism (MDRO) transmission and infection. Three databases were searched for articles from 2008 through 2018, as well as any key articles published after 2018. Findings focused on health care-associated infections (HAIs) and 3 categories of MDROs: methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE), and carbapenem-resistant Enterobacteriaceae (CRE). Chlorhexidine reduced MRSA acquisition and carriage, but no studies found significant reductions in infections. Several studies found that chlorhexidine bathing reduced VRE acquisition and carriage. Two very large studies found bathing significantly reduced HAIs, but these reductions may be smaller when HAIs are already controlled with other anti-infection measures.

Environmental methicillin-resistant Staphylococcus aureus contamination, persistent colonization, and subsequent skin and soft tissue infection.
This 12-month prospective cohort study examined households contaminated with methicillin-resistant Staphylococcus aureus (MRSA), persistent colonization, and subsequent soft tissue infection (SSTI). Households in St. Louis who had members with community-acquired MRSA SSTI were longitudinally tracked from 2012 to 2015. A baseline visit was conducted at the index patient’s primary home, followed by four quarterly visits over 12 months. With each visit, an interview and serial cultures were collected. Of the 692 participants in 150 households, including 150 children, who completed all 5 samplings; 213 (39%) showed persistent colonization with S. aureus, particularly in the nose. Nine pets (8%) were persistently colonized with S. aureus. Interval SSTI was also associated with MRSA in 76 index patients (53%) and 101 household contacts (19%).

Longitudinal, strain-specific Staphylococcus aureus introduction and transmission events in households of children with community-associated meticillin-resistant S aureus skin and soft tissue infection: a prospective cohort study.
This prospective cohort study examined methods of transmission for methicillin-resistant Staphylococcus aureus (MRSA) in households with otherwise healthy children who have a MRSA infection. From 2012-2015 households in St. Louis with children who had a community-acquired MRSA skin and soft-tissue infection were longitudinally tracked. Children with other health issues were excluded. A baseline visit was conducted at the index patient’s primary home, followed by four quarterly visits over 12 months. With each visit, an interview and serial cultures were collected. Molecular typing was done of those samples to determine the distinct S aureus strain. MRSA recipients were most likely to live in a rental situation, and were more likely to share a bedroom with a strain-colonised individual. The most likely transmission source was shared bath towels. Pets were often recipients, but rarely the sole transmission source. Frequent handwashing decreased the likelihood of novel strains being introduced into the house and emphasizes the importance of hand hygiene.

Bacterial infections in neonates following mupirocin-based MRSA decolonization: a multicenter cohort study.
This study characterized the risk of infection after MRSA decolonization with intranasal mupirocin. It concluded that in a multicentered cohort of MRSA-colonized neonates, mupirocin-based decolonization treatment appeared to decrease the risk of infection with select gram-positive organisms as intended, and the treatment was not significantly associated with risk of subsequent infections with organisms not covered by mupirocin's spectrum of activity.

Are hospital floors an underappreciated reservoir for transmission of health care-associated pathogens?
In a survey of 5 hospitals, the researchers found that floors in patient rooms were frequently contaminated with pathogens and high-touch objects such as blood pressure cuffs and call buttons were often in contact with the floor. Contact with objects on floors frequently resulted in transfer of pathogens to hands.

Enhanced terminal room disinfection and acquisition and infection caused by multidrug-resistant organisms and Clostridium difficile (the Benefits of Enhanced Terminal Room Disinfection study): a cluster-randomised, multicentre, crossover study.
The researchers determined the effects of three enhanced strategies for terminal room disinfection (disinfection of a room between occupying patients) on acquisition and infection due to methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, C difficile, and multidrug-resistant Acinetobacter. They found that the incidence of target organisms among exposed patients was significantly lower after adding UV (quaternary ammonium disinfectant and disinfecting ultraviolet [UV-C]) light to standard cleaning strategies.

Methicillin-resistant staphylococcus aureus pneumonia in critically ill trauma and burn patients: a retrospective cohort study.
The authors sought to determine the incidence of MRSA pneumonia in early-onset and late-onset pneumonia and to identify risk factors for MRSA in the trauma-burn intensive care unit (ICU). They found that the 11.4% overall incidence of MRSA pneumonia in the studied trauma-burn cohort was similar to what has been reported in other trauma populations, although MRSA was equally likely to be identified in early- and late-onset pneumonia. They suggested that risk factors other than duration of hospitalization may be important considerations in the decision to initiate MRSA-active empiric therapy for pneumonia in the trauma-burn ICU.

Perceptions of gown and glove use to prevent methicillin-resistant staphylococcus aureus transmission in nursing homes.
This qualitative study explored current use and perceptions of glove and gown use in nursing homes. Analysis of recordings of three focus group discussions revealed that direct care staff reported using gowns and gloves primarily as self-protection against contact with bodily fluids, not to prevent MRSA transmission. Glove use was described as common and more acceptable to staff and residents than gown use.

Risk of skin and soft tissue infections among children found to be staphylococcus aureus MRSA USA300 carriers.
The purpose of this study conducted in a pediatric emergency department was to examine community-associated methicillin resistant Staphylococcus aureus (CA-MRSA) carriage and infections and determine risk factors associated specifically with MRSA USA300. It found that children younger than two years were at highest risk for MRSA USA300 carriage. Lower income, recent antibiotic use, and previous or family history of skin and soft tissue infections were risk factors for MRSA USA300 carriage.

Meticillin-resistant Staphylococcus aureus (MRSA) acquisition risk in an endemic neonatal intensive care unit with an active surveillance culture and decolonization programme.
The researchers measured the association between colonization pressure from decolonized and non-decolonized neonates and methicillin-resistant staphylococcus aureus (MRSA) and MRSA acquisition to inform use of this strategy for control of endemic MRSA. They concluded that untreated MRSA carriers were an important reservoir for transmission. Decolonized patients on contact isolation posed no detectable transmission threat, supporting the hypothesis that decolonization may reduce patient-to-patient transmission.
