Low hospital staff levels increase infection rates

19.07.2007
Decreasing the number of nurses on duty in an intensive care unit (ICU) increases the risk of serious infection, according to a report published in the open access journal Critical Care.

Stéphane Hugonnet and colleagues from the University of Geneva Hospitals, Switzerland, investigated the number of patients admitted to the ICU who developed ventilator-associated pneumonia (VAP), over a four-year period. They then compared this to the number of nurses on duty for each patient in the preceding days. VAP affected over a fifth of the 936 patients who received mechanical ventilation during the study.

The team found that when there were lower numbers of nurses, patients were more likely to catch pneumonia six days or more after being placed on a ventilator. This suggests that bacteria are transferred between patients, or from one site to another in the same patient. This could be due to short-staffed nurses having less time to follow hand hygiene recommendations and proper isolation procedures or being unable to provide adequate care to the ventilated patient. The nurses’ training level had no effect on infection rates.

The authors concluded that this study backs up findings from their earlier general study on ICU infection risks, namely that employing more than two nurses per patient per day would prevent a large proportion of infections. There was an average ratio of two nurses per patient per day in the ICU during this study.

“This study shows that a low nurse-to-patient ratio increases the risk of late-onset VAP,” said Hugonnet. “It adds also to the growing body of evidence demonstrating that adequate staffing is a key determinant and a prerequisite for adequate care and patient safety.” VAP is caused by bacteria entering the lungs as a consequence of the ventilator tubing and is one of the most common preventable problem affecting critically ill hospital patients. It can cause a stay of about an average of 10 extra days in hospital at a cost of US$10,000 to $40,000.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
