About one out of 30 chemotherapy orders at three ambulatory infusion clinics had errors, and one in 50 orders had a serious error, according to a study appearing in the December 1, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study, performed at the Dana-Farber Cancer Institute, found most but not all errors were detected before they reached the patient. None was life-threatening or caused patient harm. Still, an accompanying editorial says the study underscores the need to implement safer controls of drug ordering and dispensing at chemotherapy infusion clinics.
Medication errors in hospitals are a stark reminder of the potential harm that can occur when patients are admitted to the hospital. While most medications are well tolerated, a few classes are toxic and require complex dosing regimens, such as those used in chemotherapy. Even a low error rate from these medications could potentially lead to significant harm, including death.
Aside from a few case reports in journals and popular media, little research has investigated the error rate of chemotherapy orders at outpatient clinics or hospitals. Some individual institutions that have been affected by these reported errors, such as the Dana-Farber Cancer Institute (a member of the Dana-Farber/Harvard Cancer Center, a National Cancer Institute-designated comprehensive cancer center), have made extensive changes to prevent such errors, such as computerization of the medication ordering system.

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,...
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...
