During a routine screening in 2010, personnel at Wake Forest Baptist Medical Center in North Carolina discovered Bacillus cereus bacteria in samples dispensed by their machine, the Intellifill IV. "To our knowledge, this is the first published report of a pharmacy robot being contaminated with Bacillus with resultant contamination of intravenous drug product," the report's authors write.
Bacillus is a potentially harmful bacterium that is resistant to many commonly used disinfectants, including alcohol.
Personnel discovered the contamination through quality assurance measures recommended by the manufacturer before any patients were harmed by the contaminated drugs. The implications of contaminated intravenous products can be serious, including potentially life-threatening bloodstream infections. While any adverse events were avoided, the investigation into how the machine became contaminated suggests that the current cleaning and maintenance recommendations may need to be strengthened.
The investigators traced the contamination to the machine's washing station and the tubing associated with it. Because this area is not considered a sterile part of the robot, the manufacturer does not specify a cleaning procedure for these parts beyond regular "fogging" with alcohol, using a spray bottle to clean inaccessible parts.
"To prevent other users of Intellifill IV from experiencing the same problem, the manufacturer should consider establishing a formal procedure for cleaning and maintaining the washing station, with more detailed recommendations to change the drain tube, the container, and possibly the washing station itself," the authors write. "In addition, it is reasonable to expand existing quality assurance recommendations to include surface testing of the washing station and air sampling in the center of the compartment. Last, using the robot in the pharmacy's clean room could further decrease the risk of contamination."
The findings stress the importance of routine screening of medication prepared by robotic dispensers, which are increasingly used in hospitals. "Quality assurance methods are critical to ensure ongoing patient safety," the authors write.

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....
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...
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.
