Serious proliferation of multiresistant Staphylococcus in intensive care units

14.02.2007
Multiresistant bacteria are a severe problem that costs lives at hospitals the world over. A new doctoral thesis from Karolinska Institutet in Sweden shows that the spread of disease between seriously ill patients in intensive care units is surprisingly rife.

The number of infections caused by multiresistant bacteria and mycobacteria in Swedish hospitals has risen dramatically in recent years, giving rise to prolonged care and higher death rates. The situation is most serious in intensive care units, where between 10 and 20 per cent of patients contract some kind of hospital-related infection.

Specialist physician Christina Agvald-Öhman studied the infection route of bacteria strains at a Swedish intensive care unit for her thesis. The results of her work show that the spread of infection between patients is surprisingly high. Between 70 and 80 per cent of the patients who were in care at the unit for three to five days were involved in the spread of infection.

“Infections are mainly spread via staff and equipment, which could be avoided if the hygiene rules were properly followed,” says Dr Agvald-Öhman. “By far the most important rule, which is easily forgotten, is to wash your hands properly after contact with each patient.”

The bacteria strain under study was a type of Staphylococcus normally found on the skin of healthy people, but which can easily establish itself in the respiratory passages of ill people; it is also one of the most common causes of hospital-related blood poisoning. Dr Agvald-Öhman believes that other types of bacteria are transmitted in a similar way.

Hospital-related infections not only cause personal suffering for the patients, they are also a financial burden. One day’s intensive care costs about SKr 35,000, and according to common estimates prolong hospitalisation by six to twelve days.

The study was carried out at Karolinska University Hospital in Huddinge, Stockholm County, where it has already spurred extensive action to prevent hospital-related infections.

“I’m convinced that these problems are just as serious at other intensive care units, and I hope that my results can help raise the general motivation surrounding hygiene in healthcare,” says Dr Agvald-Öhman.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
