A new measurement tool called the computerized clinical vignette can help clinicians and policymakers assess and improve the quality of physician practice while potentially reducing costs, according to a study led by a researcher at the San Francisco VA Medical Center (SFVAMC).
The vignette -- which presents a simulated patient visit to the doctor via computer -- is an accurate, inexpensive, and efficient way to measure how well physicians handle their clinical practice, the study concludes. Research findings are published in the November 16 issue of Annals of Internal Medicine. "As we investigate the quality of clinical practice, we know theres a tremendous need for improvement," says study leader John W. Peabody, MD, PhD, a staff physician at SFVAMC and an associate professor of epidemiology, biostatistics, and medicine at the University of California, San Francisco.
In order to improve care and control costs, he adds, "We need to give physicians a very precise estimate of where their strengths and weaknesses are. But in medicine, we dont get a lot of feedback. And in order to change that, we need a new measurement method."

Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
