In terms of effectiveness, short-term trials suggested onlymodest benefits of COT for chronic non-cancer pain “Short-term use of opioids [for chronic pain] is associated with modest but favorable effects on pain and physical functioning.” Papaleontiou et al, JAGS 2011.
Chronic Opioid Therapy (COT) guidelines were widelydisseminated based on low quality evidence“In the Canadian guideline, just 3 of 24 recommendations were based on RCTs.Nineteen recommendations were based solely or partially on consensus opinion.In the United States guideline, 21 of 25 recommendations were viewed as supportedby only low-quality evidence.In other words, the developers of the guidelines found that what we know aboutopioids is dwarfed by what we don’t know.” Roger Chou, CMAJ 2010.

The lack of large trials is significant given uncertainties about thelong-term safety of COT. There are initial data pointing to a widespectrum of potential adverse health effects including... System Potential adverse effects Respiratory Overdose, Sleep apnea, Community-acquired pneumonia Gastrointestinal Bowel obstruction, Chronic constipation Musculoskeletal Fractures, Osteoporosis Reproductive Hypogonadism, Infertility, Amenorrhea, Sexual dysfunction Immune system Immunosuppression, Infection Cardiovascular Myocardial infarction Oral health Xerostomia (dry mouth), Tooth decay Neuropsychological Depression, Anxiety, Apathy Cognitive impairment Hyperalgesia Opioid dependence and addiction Behavioral Opioid misuse and abuse Opioid diversion Motor vehicle accidents Baldini, Lin & Von Korff, Primary Care Companion CNS, 2012.
Given uncertainties and controversies, research was initiated atGroup Health concerning key questions How is COT being managed by physicians and used by patients? What are the risks and benefits of COT in primary care settings? Given what is known, what steps should be taken to reduce patient risks?
In a large survey, we found COT patients typically reportedmoderate to severe pain--at all opioid dose levels. Average Pain Intensity <50 mg. MED 50 to <120 mg. MED >120 mg. MED Source: CONSORT Survey (N=2119) Group Health Cooperative and Kaiser Permanente N CA
We found that most COT patients reported substantialpain-related activity limitation, increasing with opioid dose. Pain-Related Activity Limitation Days in Last 3 months <50 mg. MED 50 to <120 mg. MED >120 mg. MED Source: CONSORT Survey (N=2119) Group Health Cooperative and Kaiser Permanente N CA
We found that COT patients receiving higher opioid dosewere less likely to be working. 100% 80% 39% 36% Employment Status 56% 60% Working 18% Retired 32% 40% Not working 26% 20% 46% 30% 18% 0% Lower dose Medium Dose Higher dose <50 mg. MED 50 to <120 mg. MED >120 mg. MED Source: CONSORT Survey (N=2119) Group Health, Seattle WA and Kaiser Permanente N CA
And, we found that more than half of COT patients onmedium to high dose were clinically depressed. Percent with PHQ-8 depression scale > 10 Merrill et al., In press
We were the first to report markedly higher overdose risk amongCOT patients on higher opioid dose, others soon replicated. GHRI findings replicated in Veterans Health Administration and Canadian studies published in 2011 * * * p<0.05 * * * * **
In addition to direct risks to COT patients, opioid diversion has also been increasing, placing community members at risk of prescription opioid overdose and addiction.

In April 2011, the White House Office of National Drug ControlPolicy declared an epidemic of prescription drug abuse. “Prescription drug misuse and abuse is a major public health and public safety crisis. As a nation, we must take urgent action to ensure the appropriate balance between the benefits of these medications and the risks they pose. ”
Based on initial research, and remaining uncertainties, what stepsshould be taken now to increase prescription opioid safety? Group Health undertook major initiatives to reduce risks to patients We helped establish Physicians for Responsible Opioid Prescribing to educate physicians and advocate for safer prescribing practices to integrate research, efforts to improve care and public advocacy. Care Science Advocacy Group Health implemented a risk mitigation initiative to make opioid prescribing for chronic noncancer pain as safe and effective as possible.
In 2010, Group Health implemented uniform COT standards withpatient care plans documented in the EMR for all COT patients. Percent of COT patients with care plans Guideline implementation September 2010 Within one year, COT care plans were developed and documented in the EMR for almost all of the 7,000 + Group Health patients using opioids long-term. Trescott et al, Health Affairs, 2011
As part of this initiative, urine drug screening of COT patientswas markedly increased in Group Health clinics. Baseline Guideline Guideline (2008-9) Planning Implementation (2009-10) (2010-11) Turner et al, work in progress
From 2007 to 2011, the percent of Group Health COT patientson high opioid doses was cut in half, by reducing dose escalation. Percent of COT patients receiving > 120 mg. morphine equivalent dose Community Physicians 17.8 % > 120 mg. MED Group Health 9.4 % > 120 mg. MED Von Korff et al, work in progress
To achieve more selective and cautious COT prescribing, newpractice norms are needed. The National Summit on OpioidSafety will consider the following draft principles: Draft Principles for More Selective and Cautious Use of Opioids for Chronic Pain 1) Begin treatment of chronic pain with non-opioid modalities, including encouragement to resume rewarding life activities, gradual increases in physical activities such as walking, physical therapy, massage, cognitive behavioral therapy, chronic pain support groups, and safer medications such as anti-depressants. Learning to manage chronic pain can take time, so don’t give up on safer modalities too soon. 2) Carefully evaluate patient risks of addiction before considering opioids for chronic non- cancer pain. Ask about personal and family history of substance use problems. If available, check a Prescription Monitoring Program database to see if the patient is obtaining controlled substances from other sources. Do not overestimate your ability to identify patients who are at high risk of prescription opioid addiction.
Draft principles continued: 3) If opioids are considered, start with short-term or intermittent opioid use for severe pain flare- ups as an alternative to sustained opioid use. The claimed benefits of long-acting opioids and time-scheduled opioid dosing for management of chronic non-cancer pain have not been proven by controlled studies, and they lead to higher opioid dose. Tell patients that around the clock opioid use over long periods of time may not sustain analgesic benefits that may be needed when pain is severe. Do not be afraid of well controlled PRN use of opioids. 4) When chronic opioid therapy is considered, initiate treatment cautiously as a time-limited therapeutic trial. Agree upon criteria for decisive improvement in performance of activities in work, family and social life, and for pain control, to test whether the therapeutic trial achieves hoped-for benefits. Set expectations that the therapeutic trial will not be continued unless decisive benefits are observed. Use of opioids requires an ongoing, open and honest dialogue about pain control, function and problems with the medications. If the clinician and/or the patient is not ready for ongoing, open and honest dialogue, then opioids should not be considered. 5) Avoid opioid dose escalation to levels where discontinuation becomes difficult and risks of adverse events are increased.
Draft principles continued: 6) Taper patients off opioids (or to a lower dose if that is not possible) if benefits are limited, problems arise, or benefits for quality of life are not sustained over time. Continually revisit whether the patient is ready to discontinue opioid use or reduce dose. Many patients using opioids long-term remain ambivalent about opioid use, so opportunities to discontinue use or lower dose may arise over time. 7) Do not overestimate your ability to predict which patients will misuse or abuse prescription opioids, or even to detect opioid misuse or abuse among patients using opioids long-term. Remain vigilant for adverse medical effects of opioids as well as indications of abuse, misuse or diversion. 8) Patients who abuse opioids or develop addiction should be treated for addiction. If you are prescribing opioids long-term, referral resources for addiction treatment should be available. Management with buprenorphine may be a helpful option for some patients.
Chronic Opioid Therapy Reconsidered Please take 20 minutes to review the brief videos providing important information. The first video was developed by Group Health. The other four were developed by Physicians for Responsible Opioid Prescribing. They present expert opinions and relevant patient stories. The expert opinions are based in scientific evidence, but uncertainties remain. Most experts now agree there is markedly increased opioid-related morbidity and mortality. And, most experts now agree there is inadequate evidence to be assured that long-term opioid use for chronic pain is safe and effective. Clinicians observe that some patients do well, but patients are also harmed. The balance of benefits to harms remains controversial.
