Physician waivers to prescribe buprenorphine increases potential access to treatment
(Press-News.org) American physicians with waivers allowing them to provide office-based medication-assisted buprenorphine treatment to patients addicted to opioids were able to increase potential access to effective medication-assisted treatment by 74 percent from 2002 to 2011, according to a new RAND Corporation study.
Published in the June issue of the journal Health Affairs, the study shows that the increased number and geographic distribution of physicians obtaining waivers to prescribe buprenorphine has widened potential access to effective treatment for those with addiction to heroin or prescription painkillers.
Traditional opioid treatment programs require patients to take methadone on-site at a clinic under direct supervision of a healthcare provider. Such programs typically are located in urban areas, which leave most people in rural areas with little access to treatment. Buprenorphine, approved by the FDA in 2002, can be prescribed by office-based physicians who have completed an approved course.
"In the past, many people living in rural counties have had no practical way to get treatment. They have seen the greatest benefit from the introduction of buprenorphine and the growth in the number of physicians approved to prescribe the drug," said Dr. Bradley Stein, the study's senior author, associate professor of psychiatry at University of Pittsburgh School of Medicine and a senior natural scientist at RAND, a nonprofit research organization. "Those rural residents with addiction to heroin or prescription painkillers now have an opportunity to receive treatment with effective medications, which is an essential piece of successfully addressing the nation's recent epidemic of opioid overdoses."
Using data from the Substance Abuse and Mental Health Services Administration, the research team identified counties with shortages of waivered physicians or shortages of opioid treatment programs. By 2011, the percentage of counties with a shortage of waivered physicians fell dramatically from 98.9 percent to 46.8 percent. The change meant the percentage of the U.S. population living in a county with a treatment shortage declined from 49 percent to 10 percent.
The decline in counties with shortages in waivered physicians resulted in an estimated 74 percent increase in the fraction of the U.S. population with potential access to treatment.
With an estimated 2 million people across the country affected by opioid abuse, the research team believes the potential access to treatment through waivered physicians is critical to increasing effective treatment for these individuals, particularly outside of metropolitan areas. However, the researchers note that significant barriers to treatment still exist, including stigma, adequate insurance coverage and onerous treatment requirements.
Support for the study was provided by the National Institute on Drug Abuse. Other authors of the study are Andrew W. Dick, Rosalie L. Pacula, Mark Sorbero and Rachel M. Burns, all of RAND; Dr. Adam J. Gordon of University of Pittsburgh and the VA Pittsburgh Healthcare System; and Douglas Leslie of Penn State College of Medicine.

Getting through the pollen season can now become easier for some of the approximately 500 million people worldwide who suffer from sneezing and a runny nose, watery eyes and drowsiness during the allergy season (seasonal allergic rhinitis).
This is indicated by a controlled trial carried out by researchers from Aarhus University. The trial, which took place over two days, included 65 people with grass pollen allergies who were not receiving any medical treatment at that time. They were either equipped with a nasal filter or a placebo device.
The conclusion was that the ...
Chicago, June 9, 2015 - A more aggressive approach to treating degenerative mitral valve disease, using earlier surgical intervention and less invasive techniques, is more beneficial to the patient than "watchful waiting," according to an article in the June 2015 issue of The Annals of Thoracic Surgery.
Earlier surgical intervention using less invasive surgical techniques is better than watchful waiting for patients with degenerative mitral valve disease.
Over the 25 years observed, mortality rates remained low, hospital length of stay was shorter, ...
Athens, Ga. - Researchers in the University of Georgia's Regenerative Bioscience Center are visually capturing the first process of chromosome alignment and separation at the beginning of mouse development. The findings could lead to answers to questions concerning the mechanisms leading to birth defects and chromosome instability in cancer cells.
"We've generated a model that is unique in the world," said Rabindranath De La Fuente, an associate professor in the UGA College of Veterinary Medicine. "Because we removed ATRX protein expression only in the oocyte, the female ...
The handling of agricultural crop residues appears to have a large impact on soil's ability to retain carbon, making land management practices increasingly important, especially under a scenario where cellulosic materials become more heavily used as a feedstock for ethanol production, according to a recently published study led by researchers at the U.S. Department of Energy's Argonne National Laboratory.
"Plants and soil are carbon sinks," said Argonne climate scientist Beth Drewniak, who led the study. "Soils lock carbon away for long periods of time. But when plant ...
Computers and water typically don't mix, but in Manu Prakash's lab, the two are one and the same. Prakash, an assistant professor of bioengineering at Stanford, and his students have built a synchronous computer that operates using the unique physics of moving water droplets.
The computer is nearly a decade in the making, incubated from an idea that struck Prakash when he was a graduate student. The work combines his expertise in manipulating droplet fluid dynamics with a fundamental element of computer science - an operating clock.
"In this work, we finally demonstrate ...
One potential way to combat ongoing climate change, eliminate air pollution mortality, create jobs and stabilize energy prices involves converting the world's entire energy infrastructure to run on clean, renewable energy.
This is a daunting challenge. But now, in a new study, Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford, and colleagues, including U.C. Berkeley researcher Mark Delucchi, are the first to outline how each of the 50 states can achieve such a transition by 2050. The 50 individual state plans call for aggressive changes ...
For the past several years, Anthony Wagner has been developing a computer program that can read a person's brain scan data and surmise, with a high degree of certainty, whether that person is experiencing a memory. The technology has great promise to influence a number of fields, including marketing, medicine and evaluation of eyewitness testimony.
Now, Wagner, a professor of psychology and neuroscience at Stanford, and his colleagues have shown that with just a little bit of coaching and concentration, subjects are easily able to obscure real memories, or even create ...
