Reduced ceftaroline susceptibility among invasive mrsa infections in children: a clinical and genomic investigation.
The purpose of this study was to assess the frequency of reduced susceptibility (RS) to ceftaroline among pediatric methicillin-resistant Staphylococcus aureus (MRSA) infections. The researchers evaluated MRSA isolates at a tertiary children's hospital for ceftaroline RS. Ceftaroline RS occurred only among health care associated infections in 2.9% of isolates, and were more often clindamycin-resistant.

Stakeholder engagement in a comparative effectiveness/implementation study to prevent Staphylococcus aureus infection recurrence: CA-MRSA Project (CAMP2).
The purpose of this study was to determine whether the presence and participation of a stakeholder committee would positively impact the effectiveness of the design and execution of a home-based Methicillin-resistant Staphylococcus aureus and methicillin-sensitive Staphylococcus aureus infection prevention intervention. The trial utilized community health workers to implement infection prevention protocols in participant’s homes, including home visits, sampling household surfaces at baseline and then three months, and obtaining surveillance cultures from index patients and household members. The study assembled and convened The Clinician and Patient Stakeholder Advisory Committee (CPSAC), comprised of New York-based federally qualified health centers (FQHCs) and community health emergency departments, laboratory and clinical researchers, clinicians, and patient stakeholders. The CPSAC was tasked with trial oversight and shared decision-making and troubleshooting, and convened both in person and remotely. The researchers concluded that the inclusion and engagement of the CPSAC during the trial design and implementation was highly effective in addressing and resolving challenges in both participant recruitment and home visits.

Current infection prevention and antibiotic stewardship program practices: a survey of the Society for Healthcare Epidemiology of America (SHEA) Research Network (SRN).
This survey compares results with a similar 2013 survey that characterizes contemporary infection prevention and antibiotic stewardship program practices across 64 healthcare facilities. There was decreased frequency of active surveillance for MRSA, frequent active surveillance for carbapenem-resistant Enterobacteriaceae, and increased support for antibiotic stewardship programs.

The SHIELD Orange County project: multidrug-resistant organism prevalence in 21 nursing homes and long-term acute care facilities in Southern California.
The authors reported baseline multidrug-resistant organism (MDRO) prevalence in 21 nursing homes (NHs) and long-term acute care facilities (LTACs). They found that prevalence of MDROs was 65% in NHs and 80% in LTACs. They concluded that the majority of NH residents and LTAC patients harbor MDROs, and that MDRO status is frequently unknown to the facility. The high MDRO prevalence highlights the need for prevention efforts in NHs/LTACs as part of regional efforts to control MDRO spread.

Increasing clindamycin and trimethoprim-sulfamethoxazole resistance in pediatric Staphylococcus aureus Infections.
This retrospective observational study looked at pediatric clinical cultures between 2005 and 2017 that grew Staphylococcus aureus culture and their trends in antibiotic resistance. Methicillin resistance declined but clindamycin and trimethoprim-sulfamethoxazole resistance increased significantly.

Emergency department environmental contamination with methicillin-Resistant Staphylococcus aureus after care of colonized patients.
This study examined transmission of Methicillin-resistant Staphylococcus aureus (MRSA) in emergency departments (EDs) after care of colonized patients. The effect of MRSA infected patients’ visits to emergency rooms was studied after patients’ discharge and before environmental disinfection. Cultures from 5 anatomic sites were obtained and also from ED rooms. Nineteen of the 25 ED rooms that were occupied by MRSA-colonized patients contained greater than or equal to 1 MRSA-contaminated environmental surface. The room was more likely to be contaminated if there was more than 1 body site colonized on a patient. The strain was matched with the patient in 16 of the 19 ED rooms where MRSA was recovered. This study emphasized the importance of environmental surface disinfection to reduce MRSA transmission in EDs.

A Bayesian model of acquisition and clearance of bacterial colonization incorporating within-host variation.
The authors present a Bayesian model that provides probabilities of whether two bacterial strains could be considered the same. This will help in predicting the spread of infections such as methicillin resistant Staphylococcus aureus (MRSA).

Interplay of personal, pet, and environmental colonization in households affected by community-associated methicillin-resistant Staphylococcus aureus.
In this study, the investigators sought to determine the prevalence, molecular epidemiology, and factors associated with Staphylococcus aureus environmental surface and pet colonization in households of children with community-associated methicillin-resistant S. aureus (CA-MRSA) infection. The investigators found that household environments and pet dogs and cats serve as reservoirs of MRSA. Household member MRSA colonization burden predicts environmental MRSA contamination. The authors indicated that longitudinal studies will inform the directionality of household transmission.

Geographic surveillance of community associated MRSA infections in children using electronic health record data.
This study conducted a geographic surveillance of community-associated methicillin resistant Staphylococcus aureas (CA-MRSA) incidence in children from 2000 to 2010 in the Atlanta Metropolitan area. Census tract data was filtered to create maps of antibiotic resistant and non-resistant forms of CA-MRSA infection. Black children and children under the age of 4 were found to have increased risk for CA-MRSA. Poverty also made a difference in the rate of CA-MRSA with neighborhoods with larger households having a higher rate.

Decolonization to reduce postdischarge infection risk among MRSA carriers.
This study compared postdischarge methicillin-resistant Staphylococcus aureus (MRSA) rates in study participant who received education alone versus decolonization and education. Decolonization was done with chlorhexidine mouthwash and showers, and nasal sprays. Decolonization with education resulted in a 30% reduction in MRSA infection versus education alone.

Development and validation of a clinical prediction rule to predict transmission of methicillin-resistant Staphylococcus aureus in nursing homes.
This study’s goal was to develop and validate a clinical prediction rule that can predict transmission of methicillin-resistant Staphylococcus aureus (MRSA) in nursing homes. The researchers wanted to identify residents who were most likely to transmit MRSA to health-care workers (HCWs) on their hands or clothing during clinical care. Demographic and clinical characteristic data was used from residents of community nursing homes in Maryland and Michigan from 2012 to 2014. The clinical prediction rule that was developed was then externally validated in a cohort of Department of Veterans Affairs nursing home residents from 7 states between 2012 and 2016. Variables in the prediction model included sex, race, resident dependency on care, the presence of any medical device, diabetes mellitus, and chronic skin breakdown. The prediction model showed good performance although it showed less utility in the validation cohort.
