Attributable cost of healthcare-associated methicillin-resistant Staphylococcus aureus infection in a long-term care center.
The purpose of this study was to estimate the attributable cost of methicillin-resistant Staphylococcus aureus (MRSA) healthcare-associated infections in long-term care centers (LTCCs) within the Department of Veterans Affairs. Findings showed a significant increase in the odds of being transferred to an acute care facility and in acute care costs. These findings of high cost and increased risk of transfer from LTCC to acute care are important because they highlight the substantial clinical and economic impact of MRSA infections in this population.

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.

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.

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.

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.

Reduction of methicillin-resistant Staphylococcus aureus infection in long-term care is possible while maintaining patient socialization: a prospective randomized clinical trial.
The researchers sought to demonstrate that a novel, minimally invasive program not interfering with activities of daily living or socialization could lower methicillin-resistant Staphylococcus aureus (MRSA) disease in long-term care facilities (LTCFs). They found that the MRSA infection rate decreased 65% between baseline and year 2, with a significant reduction observed at each of the three participating LTCFs. They concluded that on-site MRSA surveillance with targeted decolonization resulted in a significant decrease in clinical MRSA infection among LTCF residents.
