A new iconic drug information system inspired by road signs

24.04.2008
Although drug prescriptions are notoriously difficult to read, prescribing errors due to a lack of knowledge of drug properties are a worse problem.

Now, a new information icon system has been developed by researchers in France. The researchers describe their system, a graphical language for medical knowledge visualisation called VCM (Visualisation des Connaissances Médicales), in the open access journal BMC Medical Informatics and Decision Making.

Jean-Baptiste Lamy of the University of Paris and colleagues recognized that doctors do not always recall, nor have easy access to, detailed drug information. They can refer to drug monographs, but this can be inconvenient and time consuming in a busy medical practice. Lamy and his team reasoned that a new symbolic language for drug information could speed up the process and help avoid prescribing errors.

The VCM graphical language uses a small set of graphical signs, akin to laundry symbols or road signs, which may be combined to build simple sentences that convey information of the kind usually described in long-winded drug monographs, such as a drug’s side effects or interactions and conditions when it should not be prescribed. The resulting system, together with the doctor’s underlying medical training, can be used to help determine the appropriate prescription for the patient.

The researchers tested VCM with a group of volunteer general practitioners to assess whether the language is easy to learn and understand and whether it works in practice. Each practitioner underwent training to learn VCM and was then tested on the meanings of the icons and combinations of icons representing different aspects of a drug monograph. Results show that physicians read VCM significantly faster than an equivalent text, with fewer errors.

"VCM can be learnt in a few hours and appears to be easy to read” says Lamy. “It will considerably speed up access to drug information. The language could also be used to enrich other medical documents and for patient electronic records” Lamy adds.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
