When a pharmaceutical company puts drug samples into the hands of residents as a form of marketing, how does it influence their prescribing behavior? To what extent are treatment decisions based on which samples are available and further, what are the implications for patient care as well as resident education? While this is a frequently debated issue, there has been little objective data describing how drug samples affect resident physicians. In a study published in the August issue of The American Journal of Medicine, researchers from the University of Minnesota and Abbott Northwestern Hospital conducted a randomized study of 29 internal medicine residents over a 6-month period in an inner-city primary care clinic. Highly advertised drugs were matched with drugs commonly used for the same indication that were less expensive, available over-the-counter, or available in generic formulation. By random selection, half of the residents agreed not to use available free drug samples. The authors observed 390 decisions to initiate drug therapy in five drug class pairs.
After selecting drug classes where samples of heavily advertised drugs were provided to the clinic, and where lower priced alternative formulations existed, the authors looked for prescribing differences between physicians who had access to free samples and those who agreed before the study to not use the samples.
There was no contact between pharmaceutical company representatives and residents – all samples were stocked in a cabinet in the clinic – and there was periodic monitoring of the cabinet to ensure that the study drug classes were available.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
