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.

Catheter-associated urinary tract infection, Clostridioides difficile colitis, central line-associated bloodstream infection, and methicillin-resistant Staphylococcus aureus.
This article provides summaries of the background, epidemiology, diagnosis, and treatment of central line-associated bloodstream infection, catheter-associated urinary tract infection, Clostridioides difficile, and methicillin-resistant Staphylococcus aureus colonization and infections. Additional prevention strategies, including those related to recent national interventions, are also reviewed.

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.
