Few primary care physicians pay adequate attention to patients taking prescription opioid drugs — despite the potential for abuse, addiction and overdose, according to a new study by researchers at Albert Einstein College of Medicine of Yeshiva University.
The study, published in the March 2 online edition of the Journal of General Internal Medicine, found lax monitoring even of patients at high risk for opioid misuse, such as those with a history of drug abuse or dependence. The findings are especially concerning considering that prescription drug abuse now ranks second (after marijuana) among illicitly used drugs, with approximately 2.2 million Americans using pain relievers nonmedically for the first time in 2009, according to the National Institute on Drug Abuse (NIDA).
"Our study highlights a missed opportunity for identifying and reducing misuse of prescribed opioids in primary care settings," said lead author Joanna Starrels, M.D., M.S. , assistant professor of medicine at Einstein. "The finding that physicians did not increase precautions for patients at highest risk for opioid misuse should be a call for a standardized approach to monitoring."
The researchers studied administrative and medical records of more than 1,600 primary care patients for an average of two years while they received regular prescription opioids for chronic, non-cancer pain. They looked at whether patients received urine drug testing, were seen regularly in the office, or received multiple early opioid refills.
Only a small minority (8 percent) of patients were found to have undergone any urine drug testing. While such testing was more common in patients at higher risk for opioid misuse, the rate of testing among those high-risk patients was still low (24 percent). Only half of patients were seen regularly in the office, and patients at higher risk of opioid misuse were not seen more frequently than patients at lower risk. Although fewer than one-quarter (23 percent) of all patients received two or more early opioid refills, patients at greater risk for opioid misuse were more likely to receive multiple early refills.
"We were disturbed to find that patients with a drug use disorder were seen less frequently in the office and were prescribed more early refills than patients without these disorders," said Dr. Starrels. "We hope that these findings will call attention to this important safety concern."
Prescription drug misuse is a major public health problem. In a 2004 NIDA report , it was estimated that 48 million people over the age of 12 have taken prescription drugs for nonmedical uses in their lifetime – which represents approximately 20 percent of the U.S. population. Opioids, central nervous system depressants and stimulants were the drugs most commonly abused.
"Most primary care physicians are attuned to these problems," said Dr. Starrels, "but they haven't put sufficient strategies in place to help reduce risks." She and her co-authors recommend that physicians adopt the following risk-reduction strategies: standardize a plan of care for all patients on long-term opioids, which includes urine drug testing; schedule regular face-to-face office visits to evaluate patients' response to opioids and evidence of misuse; and stick to a previously agreed-upon refill schedule.
The paper, "Low Use of Opioid Risk Reduction Strategies in Primary Care Even for High Risk Patients with Chronic Pain," was published March 2, 2011 in the online edition of the Journal of General Internal Medicine.

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
