AMA versus CDC Patient Education On Opioids


CDC Poster On Opioids For Chronic Pain

The easiest place to start the critique of the initiative to stop opioid overuse in this country is the patient information products for both the CDC and the AMA.  The CDC poster on this subject is shown above and is public domain.  There is more detailed patient information from the CDC at Guideline Information for Patients.  The AMA page on the same subject is at this link.  AMA web site materials are copyrighted and I did not think it was worth the effort to attempt to get that permission.   It is available free online.  How do these guidelines compare with one another and are they likely to be useful to patients?

On inspection they both seem to warn patients that there are potential health problems including addiction and death from taking opioids.  The CDC graphic advises  the patient to actively collaborate with their physician around any potential opioid prescription.  It suggests that the physician in this case will present a number of non-opioid options and a receptive patient will decide how to use them.  Apart from the 1 in 4 statistic it is almost a fairy tale approach to the problem of addiction.  Keep in mind that direct-to-consumer advertising these days frequently end with a staccato-like recitation of side effects "including death" and pharmaceutical companies are not deterred from adding that qualifier.  That suggests to me that these dire warnings are really not a deterrent to people looking for what appears to be a "cure" - at least in some cases.  The more detailed approach from the CDC guideline seems more reasonable, but both do not take into account unconscious factors on the part of both the patient and physician.  The AMA version is seriously watered down, but both lack realistic information about addiction works.

The real issue with opioids is not that 1 in 4 people end up addicted to them.  That 1 in 4 number is after all an intent-to-treat number.  There are probably at least that many people who don't tolerate opioids at all, even on an acute basis.  Taking those people out, bumps up the number of potentially addicted to 1 in 3.  The real problem here is how the addiction occurs and the implications for primary and secondary prevention.  I can tell anyone who cares to listen that the secondary prevention aspect of opioid addiction is a long and arduous process, with no guarantee of a cure at the end of it.  Imagine that you have just started a family and started out in the workplace when the addiction occurs.  Contrary to all of the hype about medication assisted treatment with buprenorphine or naltrexone, this kind of treatment does not work well for everyone.  Addiction to an opioid may require that you participate in some form of education based treatment for up to three months or take long absences from your work and family to live in sober structured environments.  The structured environments are costly and the quality of these settings cannot be assured.  What the AMA and CDC references do not show is that if you have an addiction - you might be in a very expensive treatment program and still not be interested in stopping the opiate.  You may not feel ready to quit after one or more of these treatments.  The real danger of an addiction is that it alters your conscious state to continue the addiction, even in an environment where you are supposed to be learning how to get sober and maintain sobriety.

The AMA and CDC resources are short on this aspect of opioid addiction.  These pages should tell people a couple of other things aimed at preventing addiction rather than recognizing addiction and trying to treat it after it happens.  Here are the bullet points:

1.  Practically all people at-risk know it after they have taken the first few doses of medication.  The opioid makes them feel euphoric or ecstatic.  Contrary to the popular image of heroin addicts falling asleep, the at-risk population is energized and may feel like they have become more productive than they have ever been.  That response establishes a dangerous link between productivity and opioid use.  The at-risk population also has an enhanced perception of themselves.  They may suddenly perceive themselves as having become the person they always wanted to be.  That can include the perception of a number of positive personal qualities including confidence, intelligence, and creativity.  All of these reinforcing qualities disappear once tolerance to the drug occurs.

2.  People at-risk may notice that long standing anxiety, insomnia or depression is suddenly gone.  As an example, there are many people with social anxiety in childhood and early adult life.  Social anxiety is a condition where the person is overly concerned about being judged when they are out in public.  The associated concerns may be that they will be embarrassed or humiliated.  There is often an associated performance anxiety in certain situations.  This part of the at-risk population may notice that all of those concerns are completely gone when they start taking opioids.  All of these reinforcing qualities disappear once tolerance to the drug occurs and anxiety, depression, and insomnia recur (often amplified) during withdrawal and detoxification.

3.   The concept that opioids are medications that can reinforce their own use whether or not they actually work for pain is a difficult one to grasp.  In other words, the at-risk population may want to keep taking opioids even in cases where they do absolutely nothing to alleviate pain.  In this case it is not a question of tolerance to the analgesic effects of opioids.  The opioids did not work in the first place.  Opioids are only moderately effective for chronic pain in the first place and those effects are on par with antidepressants and anticonvulsants like gabapentin.

4.  Opioids can change your baseline personality and cause you to do things that you ordinarily would never have done.   Once an addiction has been established decision-making is in the service of maintaining the addiction.  That can include any number of legal and moral decisions that that involve the people who are closest to the person with the addiction.  The repercussions of these acts are not fully appreciated until the person is detoxified and is sober from the opioid.

5.  Opioids are legendary in the American culture.  The American culture strongly reinforces the place of intoxicants in the lives of even average Americans.  Intoxicants are in the literature, the media, and even day-to-day conversations.  People tend to hoard their unused opioids, exchange them with their friends and family, and talk about the effect of these drugs with their neighbors.  To illustrate, an acquaintance of mine recently had arthroscopic surgery of the knee.  He was in a large post-op recovery area with 8 other people.  Nursing staff were approaching people and asking them what they wanted for pain relief.  The choices were hydromorphone (Dilaudid) - a potent opioid, oxycodone-acetaminophen (Percocet) - a less potent opioid, and ibuprofen - a non-opioid.  The vote in the recovery room was 8-0 in favor of hydromorphone.  That vote parallels the disproportionate increase in emergency department visits for complications from hydromorphone relative to all other opioids.   Of course there are many variables at play, but I am suggesting at least one of them is the reputation that hydromorphone has in American culture as a potent euphoria producing opioid.

6.  Part of the American legend is that opioids are the magic bullet for pain.  The corollary is that if the doctor would just give me enough of this drug - my pain would be gone.  The important distinction here is chronic pain.  Across large populations there is no medication that will get rid of chronic pain.  For many people, no treatment at all, treatment with a non-opioid medication, or treatment with a different modality like cognitive-behavioral therapy works much better.

There are all important points for people to know before they start taking opioids.  I think that a clinical trial is indicated to see if people with this information do better than those without it.  If I was designing that trial, I would have an intervention that advised people to stop taking the medication and call the physician immediately if they experienced any change in their conscious state like the ones I described in points 1, 2 or 3 above.

Stopping opioid addiction well before it is established is the preferred intervention.  There is certainly effective treatment once an addiction has been established but it can be long, expensive, difficult, and the outcome is never guaranteed.  Anyone who starts to take an opioid needs that level of transparency.

Assault rifles, high capacity magazines, background checks and reverting to form


That is what it is coming down to according to the talking heads on the Sunday morning TV circuit this week.  Both the NRA and several politicians agree that there are not enough votes for an assault weapons ban.  There may be enough votes for a high capacity magazine ban but both sides acknowledge that these clips are inexpensive and there are already a lot of them out there.  The background checks issue is also debatable.  The NRA and the pro-gun factions are talking a lot about mental illness and needing to have a mechanism to prevent people with mental illnesses from getting guns.  There is minimal discussion of improved mental health services.  On CNN Sunday  morning there was acknowledgement that during tough budgetary times the line items supporting mental health treatment are the first to go.

So basically despite all of the hype about how the Sandy Hook incident was going to energize politicians to actually solve a problem – they appear to be rapidly reverting to form and not solving anything.  The NRA President seemed confident that nothing would happen (the NRA opposes any assault weapons ban or high capacity magazine ban), but cautioned that the President has a lot of political capital and might be able to influence the high capacity magazines.

I wanted to file this post tonight before the final recommendations of the Vice President because I think that there have been two recent articles in the medical literature that are very relevant. At the legislative level Jerome Kassirer, MD has a recent article in Archives of Internal Medicine. Dr. Kassirer is a former editor of the New England Journal of Medicine and I corresponded with him on this issue nearly 30 years ago.  He clearly has not lost interest over the years and brings several concepts into focus in his editorial. The first concerns the fundamentals of screening and how any effort to identify potential shooters would result in the false positives greatly outnumbering the true positives and how that renders screening impractical.  His primary focus has to do with countering political initiatives.  As an example the National Center for Injury Prevention and Control at the CDC is currently prevented from studying gun related injuries.  He advocates for countering that.  He advocates for a comprehensive analysis of gun ownership.  He also advocates for resistance to any laws that restrict physicians being able to talk about firearms with their patients. He wants to see universal background checks from gun purchases, gun safety devices including coded weapons, and restrictions on large capacity magazines and sales of large amounts of ammunition. His article refers to firearms as "Weapons of Mass Destruction".  Small arms and light weapons are in fact a major global problem.  This Federation of American Scientists primer highlights the issue and the fact that there have been over 1 million deaths due to small arms in the past decade. Some advocacy organizations estimate that as many as 250,000 people per year are killed by small arms fire worldwide.

The second very important article comes from the Journal of the American Medical Association. The authors of this article emphasize the public health approach to curbing gun violence. This is a very important concept that people have a difficult time grasping. Whenever I bring up the issue of psychiatrists being involved at the level of primary and secondary prevention most people distill that down to whether or not psychiatrists can predict violence.  A public health approach to violence prevention is much more comprehensive and multidimensional.  The authors give several good examples in this paper including modifying sociocultural norms.  They use the example of tobacco being media symbol of “modernity, autonomy, power, and sexuality" and how that was changed.  They suggest an analogous campaign to equate gun violence with weakness, irrationality, and cowardice. The article has a table that has 18 evidence-based public health interventions that have been successful in other areas that could be applied to gun violence.  This is actually the preferred strategy that I have been advocating for the past decade and the authors of this article state it very eloquently.

At this point in time it will be interesting to see if the Vice President's recommendations include any of the interventions suggested by these two articles or the recommendations from the APA.
