The study, published in the June issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America, suggests that this progress is likely related to prevention strategies now common in hospitals across the United States.
CLABSIs are caused when bacteria or yeast enter the bloodstream through a tube called a central line that is placed in a large vein in a patient's neck or chest to give medical treatment. Central lines are commonly used in ICUs and can remain in place for weeks or months. When not put in correctly or kept clean, central lines can become a route for germs to enter the body and cause serious bloodstream infections. CLABSIs result in thousands of deaths and significant excess costs to the U.S. healthcare system, yet research shows that these infections are preventable.
Substantial progress has been made over the past two decades in reducing the number of CLABSIs that occur among patients in ICUs in the U.S. This study, which estimated between 462,000 and 636,000 CLABSIs occurred in non-neonatal ICU patients during 1990-2010, found that reductions in CLABSI rates led to between 104,000 and 198,000 fewer CLABSIs than would have occurred if rates had stayed the same as they were in 1990.
"These findings suggest that technical innovations and dissemination of evidence-based CLABSI prevention practices have likely been effective on a national scale," said Matthew Wise, PhD, lead author of the study. "These successes help bolster perceptions that healthcare-associated infections are preventable."
New technologies have been developed over time to prevent healthcare-associated infections in general and CLABSIs specifically. CDC guidelines have promoted better central line insertion and maintenance practices. Infection control bundles, which are groups of prevention practices that are put into place at the same time and use collaborative networks of healthcare organizations to educate providers about best practices, have been used to improve adherence to recommended practices.
Cultural change and the transformation in behaviors of healthcare workers significantly affect the reduction in healthcare-associated infections, as seen in the 2006 Michigan Keystone Project. The project implemented five evidence-based preventive strategies recommended by the CDC and focused on changing provider behavior through addressing safety culture, incorporating a centralized education program for team leaders at each institution, and closely collaborating with infection control personnel. The intervention was extremely successful, nearly eliminating CLASBIs in more than 100 ICUs.
Despite apparent success, this study estimated that about 15,000 CLABSIs still occurred in ICUs during 2010. Seventy percent of these infections occurred in teaching hospitals with more than 200 beds. The concentration of CLABSIs among ICU patients in medium and large teaching hospitals suggests that a targeted approach may be needed to continue reducing CLABSIs among ICU patients nationally.
In a commentary published alongside the study, several limitations of this research were also noted, including the use of definitions by CDC for purposes for which they were not originally designed, the idea that every CLABSI is preventable, and the possibility that zero infections may not be an achievable goal in all circumstances.However, Eli Perencevich, MD, and colleagues stated that "this is encouraging news.... Anyone who has spent the past 10-20 years as an infection preventionists or hospital epidemiologist can attest to how evidence-based methods and cultural change have had a real and lasting impact on infection rates." As improved prevention efforts are identified for healthcare-associated infections, including central line associated bloodstream infections, SHEA and CDC will continue to work together to improve the National Healthcare Safety Network to meet the challenges ahead.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
