Wound infections cheaper than we thought

28.08.2006
The cost of infections post surgery and that first appear after a patient's discharge from hospital is 50 times less than previously estimated, according to a study by Queensland University of Technology.

Dr Nicholas Graves, from QUT's Institute of Health and Biomedical Innovation, said the true cost of surgical infections post hospital discharge was just $74 - not the thousands other studies have suggested.

The findings of his study were published in the prestigious US journal Emerging Infectious Diseases titled Costs of Surgical Site Infections that appear after hospital discharge.

"Our study found that postdischarge surgical infections caused much lower costs than previously thought, even when costs are viewed from a societal perspective," Dr Graves said.

"This study contradicts other studies which have found the economic cost of a case of a surgical site infection after hospital discharge was almost 50-fold the estimate we have reported.

"Up until now little has been known of the costs of postdischarge wound infections but studies suggest that they are large with health services and patients incurring costs and subsequent production losses."

The study looked at 449 patients who underwent surgery.

"Of these 449 patients, 38 were diagnosed with a surgical site infection or wound infection that appeared after their release from hospital."

He said when taking into account the cost of health care services, work losses and outof- pocket expenses by the patient, the cost of infection was $74.

"We arrived at this figure by using statistical techniques to estimate how much a postdischarge wound infection contributed to these costs, while controlling the effects of other factors that also cause costs," he said.

Dr Graves said previous studies failed to zero in on this statistical information, thereby adding costs which would otherwise be attributed to the normal healing of a patient post surgery.

"Basically we included more control variables in our statistical equations and so explained more of the variation in cost outcomes.

"This reduced the amount of costs attributed to wound infections."

Dr Graves said there was a need to understand the true cost of surgical site infections so that policy makers could accurately predict the cost savings from prevention programs.

"This information will enable good quality infection-control decisions to be made," he said.

"Biased estimates of cost savings will lead to poor decision making about infection control."

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
