Antibiotics get a “time-out”

18.11.2014

MUHC study examines the effect of regular re-evaluation of antibiotic use on cost and C. difficile infection rates

Resistance to antibiotics is an important health concern that affects both the spread of infections, like Clostridium difficile, and the medication budget. Researchers at the McGill University Health Centre (MUHC) examined the effectiveness of adopting an antibiotic “time-out” during treatment, which involves regularly re-evaluating the treatment strategy as the clinical situation evolves.

The study, published in this month’s issue of the Annals of Internal Medicine, showed that structured time-outs, using a locally developed online checklist, resulted in decreased antibiotic costs coupled with decreased use of targeted medications. There was also a small decline in C. difficile infections.

“According the Centers for Disease Control and Prevention (CDC) nearly 50 per cent of antibiotic use is unnecessary or inappropriate,” says first author of the study Dr. Todd Lee, MUHC attending physician and assistant professor of Medicine at McGill University. “Given this statistic, and our own concerns about antimicrobial resistance, we decided to implement a tailored time-out program at the MUHC and evaluate its effectiveness.”

Time out means clinical review
The study involved 679 patients and was conducted over a period of 18 months on the internal medicine clinical teaching units at the Montreal General Hospital of the MUHC. The time-out concept was introduced to physicians and trainees as an opportunity to review the indication, dose and duration of antibiotic use when new clinical information became available.

The staff were also educated on antibiotic guidelines and participated in a twice weekly structured review of all patients receiving antibiotics. This approach led to changes in doses, duration of treatment, and changes in the type of antibiotic prescribed, which in turn led to cost reductions and a small decrease in C. difficile.

“Our approach tied specific education about antibiotic use with a structural tool to review and guide this use,” says senior author of the study Dr. Louise Pilote, researcher at the Research Institute of the MUHC, chief of General Internal Medicine at the MUHC and a professor of medicine at McGill University. “This could translate into better prescribing practices. In general, physicians believed the process improved their comfort with antibiotics and provided clinical value.”

“We hope this approach will permit a more widespread implementation of antibiotic auditing and that this will affect future prescribing, turning today’s high rates of inappropriate antibiotic use into tomorrow’s historical footnote,” adds Dr. Lee.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
