MRSA carriage rates vary widely in nursing homes

02.12.2010
A study published in the January 2011 issue of Infection Control and Hospital Epidemiology finds that a high percentage of nursing home residents carry Methicillin-resistant Staphylococcus aureus (MRSA), and suggests that some nursing homes could be doing more to prevent the spread of the bacteria, which can lead to hard-to-treat infections.

The study, which looked at 10 nursing homes in Orange County, California, found that 31 percent of the residents who were tested were carrying MRSA (meaning they could pass the bacteria along to others, but were not necessarily sick with infection).

That rate is substantially higher than rates found in hospitals and even intensive care units, according to Susan Huang, medical director of epidemiology and infection prevention at the University of California Irvine Medical Center and one of the study's authors.

The study also found, however, that carriage rates in each of the individual facilities in the study varied widely, from a high of 52 percent in one facility to a low of 7 percent in another.

"The high overall levels of MRSA are reason for concern," Huang said. "But the variation in rates between facilities may be good news because it suggests some facilities are finding effective ways to contain the bacteria."

Nursing homes have long been considered high risk facilities for MRSA infections. However, few studies have compared multiple facilities in one area to look for variation in MRSA carriage.

The researchers took nasal swabs from a sample of 100 residents in each of the 10 homes. They also took samples from 50 people at each home at the time they were admitted to get an idea of how much MRSA was coming into each facility.

The study found that a nursing home's rate of MRSA carriage was not simply a result of how much MRSA came in with new residents, and suggests that some homes do a better job than others of containing the bacteria once it arrives. For example, two nursing homes in the study had identical MRSA intake rates of 12 percent, but one of those homes had an overall MRSA carriage among its established residents of 22 percent, while the other had a rate of 42 percent.

The next step, Huang said, is to find out exactly what these facilities are doing to better contain MRSA.

"The social environment in a nursing home has a positive influence on residents, who are encouraged to frequently mingle," Huang said. "We don't want to stymie that residential feel which can be very important to mental and physical health, but we think there's more to be learned about what nursing homes can do to contain MRSA."

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
