Doctors’ responsibility in opioid crisis
Barbara Sibbald | CMAJ | Nov.18, 2016
Canadian doctors need to stop prescribing high doses of opioids to patients with pain and slowly taper off patients already on high doses, said the keynote speaker at the national Opioid conference in Ottawa, Nov. 18.
Illicit opioids are contributing to the current opioid crisis, but so too are physician’s prescribing practices, said Dr. David Juurlink, head of Clinical Pharmacology and Toxicology, Sunnybrook Health Sciences Centre in Toronto.
“We have, by our prescribing — well intentioned prescribing in most cases — opened a bit of a Pandora’s box and flooded the market with drugs that don’t work as well as we were taught and aren’t as safe as we were taught,” he told some 250 addiction and pain experts, policymakers and others.
“We really have been misled about the role of these drugs and how to use them, by companies who have made billions of dollars in the process. It’s time for some de-education,” Juurlink told CMAJ.
During his keynote address, Juurlink delved into the evolution of the current problem, including Purdue Pharma’s educational materials, which were distributed to most Canadian medical students and downplayed oxycodone’s negative effects. In a free book that Purdue distributed to medical students it said the risk of addiction was only 1%. Juurlink says there’s no evidence this is true.
But physicians wanted to be able to help patients with chronic pain. “It was a message we wanted to hear, so sales have gone through the roof.”
Purdue pled guilty to misbranding its product in the United States and paid $600 million in damages in 2007.
Federal Minister of Health, Dr. Jane Philpott, echoed Juurlink’s concerns, telling the conference that Canada’s dispensing levels are the second highest in the world, “and those dispensing levels are strongly associated with harm.” “People can transition from prescription use to problematic use and sometimes seeking drugs illicitly.”
Properly used, opioids can help people in serious pain, said Philpott. ” We need to balance the risks with the benefits and make sure there are appropriate safeguards in place.”
“We can’t prescribe them as we have in the past 20 years,” added Juurlink, “we’ve caused so much harm to pain patients with that practice.”
It’s hard to justify starting with doses more than 50-60 mg/day, he told CMAJ. “By the time you get into the 100s [of mg/day] that’s a testament of the failure of opioids to solve your patient’s problem. Some patients are taking 1000 mg/day; he knows of one taking 5000.
But he cautions doctors against abandoning patients and cutting them off. “I can’t say that strongly enough. When that happens it’s a disaster. The patient goes into withdrawal and will take whatever they can get their hands on.” He advocates slowly tapering down doses but acknowledges that won’t work in all cases.
Currently, physicians use US Center for Disease Control guidelines, but these don’t provide direction on what to do with patients on high doses.
Juurlink has joined forces with Gordon Guyatt, distinguished professor at McMaster’s Department of Clinical Epidemiology and Biostatistics, and others, to develop new Canadian guidelines for prescribing opioids for chronic pain, which they plan to submit for publication in March 2018.
The new guidelines won’t be popular with the drug companies, Juurlink predicts. “They aren’t going to be popular with doctors who think they’ve been doing it right all along by prescribing extraordinary doses, but the notion that high doses of opioids is an intervention that affords patients benefits in excess of harms is a notion that can’t die out soon enough.”
This Opioid Conference, followed by the summit on Nov. 19, is the federal government’s second effort at a national opioid strategy. In 2013, The National Advisory Council on Prescription Drug Mis-use, released a report with 58 measures, but they were not prioritized, says Juurlink, and responsibility for measures such as ensuring an evidence base, were never assigned to anyone. “It hasn’t delivered.”
This time may be different. “We are absolutely committed to turning this crisis around,” said Philpott at a press conference. “We need a comprehensive, pan-Canadian approach. She acknowledged this will take time and require a multidisciplinary approach that includes addressing the social determinants often underlying opioid misuse.
The federal government will soon announce a national housing strategy and better access to better mental health care, like cognitive behavior therapy for pain or addiction, said Philpott. She also acknowledged that specific resources will be needed for “further announcements on other work we are going to be doing.”
“We have made it clear this is a human crisis and we will work to find the tools that are necessary.”
Ontario’s Minister of Health and Long-Term Care, Dr. Eric Hoskins, who co-hosted the conference with Philpott, said that while Ontario would like more federal money, the provinces and territories also have a responsibility to address this crisis. “We have to harness the resources including provincial resources to address this.”
