Researchers find Clostridium difficile is more common than MRSA in southeast community hospitals

22.03.2010
Infections rates are comparable to other HAIs

Researchers studying epidemiology of healthcare-associated infections (HAIs) in community hospitals in the southeast U.S. found that rates of Clostridium difficile infections (CDI) surpassed infection rates for methicillin-resistant Staphylococcus aureus (MRSA).

Scientists also discovered that healthcare-associated CDI, which is a bacterium that causes diarrhea and more serious intestinal conditions such as colitis, occurs more often (21 percent) than healthcare-associated infections due to MRSA. In addition, healthcare-associated CDI occurs approximately as often as healthcare-associated bloodstream infections and combined device-related infections.

"Despite the amount of attention given to MRSA, our study shows that CDI has emerged as the leading healthcare-associated infection in our network of hospitals," said Becky Miller, MD, Duke Infection Control Outreach Network, Duke University. "In addition, our study likely underestimates the true scope of the problem since we did not include cases of community-onset healthcare-associated CDI."

This is the first large study to use patient level surveillance data (i.e. numerators and denominators) to compare the rates of healthcare-associated CDI and MRSA. The study was presented today at the Fifth Decennial International Conference on Healthcare-Associated Infections. Previous studies were based on estimates using hospital ICD-9-CM discharge diagnosis codes.

Dr. Miller and her colleagues studied 30 community hospitals in the Southeastern United States which are members of the Duke Infection Control Outreach Network (DICON). Over the 18-month period, which included more than 2 million patient days, researchers compared 607 cases of CDI and 508 cases of infections due to MRSA.

To better understand and identify infection trends, researchers also examined 949 other cases of HAIs. They found bloodstream infections occurred in 481 patients on general hospital wards and device-related infections occurred in 468 patients in intensive care units (ICU). ICU device-related infections included 197 catheter-associated urinary tract infections, 102 ventilator-associated pneumonias and 182 catheter-associated bloodstream infections.

"These findings are a reminder that prevention priorities must include the prevention of CDI", said Dr. Denise Cardo, director of CDC's Division of Healthcare Quality and Promotion. "CDI is an important cause of healthcare-associated infections and deserves attention."

Dr. Miller noted that additional epidemiologic studies are needed to determine whether prescribing practices, geographic differences, hospital characteristics, or other factors affected infection rates found in this study.

The Society for Healthcare Epidemiology of America (SHEA), the Centers for Disease Control and Prevention (CDC), the Association for Professionals in Infection Control and Epidemiology (APIC), Inc. and the Infectious Diseases Society of America (IDSA) are convening the Fifth Decennial International Conference on Healthcare-Associated Infections 2010, the scientific event to set the agenda for preventing healthcare-associated infections for the next decade March 18-22, 2010 in Atlanta, GA.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

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...
