Using opioids to manage chronic pain has
been debated in the medical community for decades, but recently the conversation
erupted into controversy.
Oakley said that was due in part to "an aggressive plan to eradicate diversion
of OxyContin" launched by the DEA after media reports about abuse of the
narcotic painkiller were blown out of proportion.
The DEA was pressured by the U.S. Department of Justice to respond to the
perceived problem, he said.
"Many reports were exaggerated or unfounded," he said.
Diversion occurs when legal drugs are used illegally, such as when prescription
painkillers are sold on the street.
Since the DEA began investigating doctors, including one in Billings, a chill
has been cast on the doctor-patient relationship, and some patients in pain are
not receiving adequate care, Oakley said.
The DEA opened an investigation of Richard A. Nelson, a Billings neurologist who
treated chronic-pain patients with opioids, several months ago. Nelson's
prescription-writing privileges were suspended, and many of his patients claimed
they could not find other physicians to treat them.
A DEA spokesman said on Friday that no criminal charges have been filed against
Nelson, and the investigation into his medical practice continues. He remains in
good standing with the state Board of Medical Examiners.
At the Northern Rockies Regional Pain Center, patients treated with opioids are
closely monitored for signs of abuse or diversion, said Dr. Michael Schabacker.
To receive opioids, patients must sign a contract and consent to regular urine
tests, Schabacker said. The tests help physicians determine whether patients are
taking the drugs prescribed to them and whether they are taking them as
instructed.
"Absence of the drug in urine is a sign of diversion," he said. "Unsuspecting
chronic-pain patients have had family and friends emptying their pill bottles as
soon as they got home and putting other tablets in there."
Most patients at the pain center are happy to provide urine samples, he said.
"A lot of patients with chronic pain have a lot of concern about how they're
viewed. They feel the need and use of these opiate medications is in some way
unsavory," Schabacker said. "People are anxious and oftentimes offer to provide
their screening."
Patients who show signs of addiction are referred to chemical-dependency
programs, but many sever their relationship with the pain center rather than
submit to an evaluation.
Addiction to prescription painkillers is estimated to occur in 3 percent to 20
percent of people who use them.
