Opioid Substitution Therapy: Treatment vs. Recovery
Opioid Substitution Therapy has been a controversial topic. Somehow it is easier for the addiction recovery industry to accept medications such as Disulfiram with its aversive effect or acamprosate which does not carry the risk of approximating the state of alcohol intoxication and because studies have suggested that it is only effective in conjunction with psycho-social interventions. OST, on the other hand, uses opioid agonists or partial agonists that act in similar ways to the drugs of dependence, albeit without the same quality of high, and this, some have suggested, shifts the addiction from opioid dependence to another dependence and may be of more harm than good to the addict.
Methedone, the original medication of choice in OST, has been described as both saviour and devil by addiction professionals, lay counsellors and those recovering from or still suffering from addiction. More recently Buprenorphine has taken centre stage. At any rate, it has always been proposed that it is “Medication Assisted Treatment”, with treatment being some form of psycho-social intervention, while it is the medication that is the add-on in this process of recovery.
Because of this thinking OST has largely been used as a temporary means of managing the short-term issues of dependence i.e. detox. Recent research, however, has shown that rather than being a supplement to treatment, OST may be the treatment itself. Two recent studies both suggest that adjunctive counselling and/or CBT do nothing to improve outcomes. These are also consistent with previous studies, although more adamant (Fielin, Pantalon, & et al, 2006).
This research flies in the face of traditional “recovery” based thinking and there is now a debate between two seemingly opposing factions. It is “Recovery” versus “Treatment”, and as more and more addiction treatment professionals accept that addiction is a brain disease that can be treated by medication, and as medication for other addictive substances emerges, this topic is going to be more hotly contested. And there is a lot at stake: If addiction can be treated by a series of 15 minute General Practitioner office based interventions a lot of people will be out of a job, the rehab industry would shut down and there would be little need of 12-step fellowships. On the other hand the insurance companies would save millions while the pharmaceutical companies would make billions.
So what is this debate all about? Let’s start by looking at the two research papers I have mentioned above.The Weiss Study
One study (Weiss, Potter, & et al, 2011) looked at over 600 prescription opioid dependent individuals who received buprenorphine in a 2-phase randomized control trial.
What the study concluded was:
· Addiction counselling made little or no difference to outcomes
· Tapering, even after 12 weeks resulted in poor outcomes
· Those who were stabilized on buprenorphine had considerably better outcomes
· Physician initiated office based treatment is possible
For the purposes of this article, what is important in these findings is that drug counselling made almost no difference. What should be noted, however, and what may be of importance, is that the majority of the patients in this study where employed, well educated, had short histories of opioid dependence and virtually no polysubstance use.
Although this study does not provide a complete description of the Opioid Dependence counselling they used, it sounds a lot like psycho-education and CBT: “Counsellors educated patients about addiction and recovery, recommended self-help groups, and emphasized lifestyle change. Using a skills-based format with interactive exercises and take-home assignments, ODC over a wider range of relapse prevention issues in greater depth than did Standard Medical Management, including coping with high-risk situations, managing emotions, and dealing with relationships.”
In early 2013 headlines proclaimed “CBT is not effective in treating heroin addiction” (or words to that effect) after the publication of a study by David Fielin and others at Yale University School of Medicine (Fiellin, Barry, & al, 2013).
This study “conducted a 24-week randomized clinical trial in 141 opioid-dependent patients in a primary care clinic.” One group received only physician management while getting their buprenorphine, while the other group received this plus CBT.
The conclusion: CBT added no benefit.
Why these findings are controversial is because it has always been assumed that psycho-social interventions form the core of addiction treatment and recovery from the addicted state. A Cochrane Review entitled “Psychosocial and pharmacological treatments versus pharmacological treatments for opioid detoxification” (Mato, Minozzi, Davoli, & Vecchi, 2011) concluded: “The review authors searched the medical literature and found evidence that providing a psychosocial treatment in addition to pharmacological detoxification treatment to adults who are dependent on heroin use is effective in facilitating opioid detoxification.” This seems to conflict with the findings of these other studies.
What research certainly does tell us more clearly is that Opioid Maintenance Therapy does keep patients engaged in therapy and keeps them abstinent longer (Mattick, Breen, Kimber, & Davoli, 2009) (Sees, et al., 2000) (Kleber, 2007) (Caldiero, Parran, CL, Piche, & B, 2006) (Donovan, Knox, Skytta, Bayney, & DiCenzo, 2012). There appears to be little research doubt that open-ended Maintenance Therapy is better than using OST as a means of detox.So why the controversy?
If one looks at the various discussions that take place between addiction professionals and those recovering from addiction on sites such as The Fix and LinkedIn, we can easily see that two camps have emerged.
I know that many will criticise the names I have given these two camps, they are not perfect, and I know that there are many who fit somewhere between the two, but for the purposes of this article I have chosen these names and I have defined them as such:
Those that believe that abstinence means that long-term OST is not an option, or is somehow second rate, and that there should always be the goal of medication-free recovery. They also believe that medication is an adjunct to other treatment modalities.
This camp says that indefinite OST is what the research is saying is effective, and they further believe that OST is the treatment in itself, and anything else is at best an adjunct, and often not necessary.
Until recently you could not go to Hazeldon and be on OST. Most of the Minnesota model based recovery industry is still firmly in the “recovery” camp. They are/were firmly abstinence based. In the world of celebrity and television the program “Celebrity Rehab with Dr Drew” has reinforced this school of thought: Dr Drew claims that methadone “takes your soul away”. To reinforce this view, here is an extract from an article from the Canadian press:
Here is another typically representative comment from a LinkedIn discussion in a closed Addiction Professionals group:
There are whole websites dedicated to the cause, and they are evangelical about the matter: check out the site called www.subsux.com. Filled with graphic descriptions and an alternative dictionary of expletives, the editor of the site says that:
On the other side of this camp are the likes of Dr Mark Willenbring, former director of Treatment and Recovery Research at the National Institutes of Alcohol Abuse and Alcoholism and now CEO of Altyr, who made the following comments in a discussion on the LinkedIn Addictions Professionals Group:
And then from private correspondence with Dr Willenbring:
And then again from the otherside:
And in case you were wondering about my own beliefs, here is my response:
But does that mean that I am firmly in the treatment camp? Certainly not. I have a lot of worries about us seeing OST as a complete treatment by itself. I have criticised the Yale study in a previous article which can be found on my blog site: www.addictioncapetown.blogspot.com. Some of my thinking about long-term use has changed in the face of research, but essentially my criticisms of the research findings as reported and perceived still stand:
Most of my criticism of the Yale study can be extended to the Weiss study, and indeed most other studies that propose medication as the end in itself revolve around the following main issues:
· They measure the wrong thing
· They measure it over too short a time
· They exclude some significant populations
· They focus on CBT as the counselling approach with which to compare outcomes
· They ignore other aspects of recovery
What should we measure when it comes to recovery from addiction? If we regard abstinence as the measure of success, then certainly OST is successful. If we see heroin addiction as equalling heroin dependence, I think we are missing the root of addiction. Through various processes, and on many levels, those with an addictive disorder have developed a set of thinking patterns and behaviours which are often not compatible with the achievement of their life goals. The drug has a salience that exceeds mere physical dependence, there is a lot invested in the processes and relationships of the addicted state and to simply measure abstinence is not giving a clear picture. The Weiss research reports that there is little or no change in levels of criminal behaviour, for instance (Weiss, Potter, & et al, 2011).
We should be measuring quality of life as well, in my opinion.
Most studies, with a few notable exceptions, report on relatively short-term outcomes. Certainly the studies I have referred to in this article have focused on a maximum of 6 months after treatment initiation. We also know that in these studies if the patient discontinued use the relapse rate was >90%. My question is: Is long-term OST sustainable? We know that adherence to chronic medication is not good – about 50% (Brown & Bussell, 2011), so this does not bode well for continued sobriety.
The perception created by the Yale paper, especially evident in the interviews with the researchers and in the press, is that those suffering with opioid addiction can be cured with medication. What they fail to point out is that within the “addicted” group there are a large number of patients with comorbidity and those who clearly self-medicate. There is little doubt that these populations require further interventions, and if we start presuming that a simple office initiated medication based regimen will be sufficient for this population we are naive.They focus on CBT as the counselling approach with which to compare outcomes
I agree that CBT is a fair place to start when comparing various modalities of treatment for addictive disorders. CBT seems to be the recommended intervention, but then again I have similar criticisms of CBT studies as I do of the Yale study. Most studies focus on abstinence not quality of life and short periods of up to 12 months after treatment initiation. Most people seeking treatment have been users of their drugs or activities of choice for many years. The mean using years in the Yale study was 8.
CBT in addictions treatment focuses on the “here and now” and is essentially designed to bring about behaviour modification, prevent relapse and provide techniques to reduce cravings. It does this fairly well compared with other modalities in short-term comparisons, but there is little difference when compared with other modalities in longer term studies.
So, essentially, you are double-treating the same issue. No wonder CBT seems to add little value. Medications work better when it comes to short-term behaviour modification. But do they work better in the long-term? We will have to wait and see.
My criticisms of the Recovery Camp are:
· They place undue emphasis on 12-Step recovery
· They believe OST is not abstinence
· They tend to ignore the evidence
Both in the outpatient and inpatient settings, the recovery camp tend to place too much emphasis on 12-step programs. In-patient facilities often charge a fortune for what are essentially nothing more than a bunch of 12-step meetings in a draconian environment. Out-patient settings are much the same and often focus on confrontational styles of intervention as laid out in many 12-step facilitation manuals. In my mind, while 12-step programs are a fantastic and free resource and undoubtedly work for some, they have little place as a stand-alone treatment modality in the professional setting.
Along with 12-step recovery comes a number of other issues that are problematic in the professional addiction care setting, which I will not discuss here, but there is one major problem:
Abstinence is where it starts and ends in the recovery camp. You must abstain from all mind-altering drugs. Full stop. Some 12-step programs will not allow those on OST to hold service positions. The more radical ones say that taking an opioid for pain management is relapse. Just like the treatment camp, but in reverse, they see dependence as addiction.
To consider one of these camps as either definitive or irrelevant would be missing an opportunity to find a more complete and balanced approach to addiction care. And although I used him as an example of the “treatment” camp, Dr Willenbring also wrote this to me in our private correspondence:
Perhaps the answer lies in knowing when and how to apply each of these modalities. I would agree with Avial Goodman (Goodman, 2001) who suggests that there are 4 phases of recovery from an addictive disorder:
1. Behaviour modification
3. Character Healing (personally I prefer Capacity Building)
I would suggest that medication and short term “treatment” therapies like CBT (as applied in addiction treatment), are best suited to the first two phases while more “recovery” orientated interventions, such as life-skills, psychodynamic therapies, longer term CBT and peer support groups are more suitable for the final two phases.
So where does long-term OST fit in? Well, for some opioid addiction is a means of self-medicating a sluggish opioid system, and so they would need to compensate for this in order to feel “normal”. Perhaps this is pre-existing or as a result of extended substance abuse, either way the opioid absent system is not a comfortable one, and so they would find themselves vacillating between behaviour modification and short-term stabilisation. Surely for this individual it would be better for them to stay on indefinite OST so as to maximize their ability to engage in long term therapy?
Further, I would like to suggest that addiction takes place across three planes:
· Neurobiology – Neurochemistry
· Thought – Behaviour (short-term and long-term)
· Microsystem – Macrosystem
Each of these planes interact with and influence each other. So, for example, the neurobiology – Neurochemistry plane will have an effect on the other planes, to a greater or lesser degree. In the case of OST, this will have an almost immediate effect on the short-term Thought-Behaviour plane (the same plane where brief CBT therapies operate). These changes in behaviour can, in turn, influence the Systems plane. Positive feedback from the system will in turn influence the Thought-Behaviour plane and the Neurological plane and so on. In cases where there has not been long term abuse that has caused significant damage to the Thought-Behaviour plane or the Systems plane, I would suggest that OST may be enough to bring to life the process described here, and this will be enough for the capacity building and self-renewal mentioned above to take place.
For most opioid abusers, however, the Systems and long-term Thought-Behaviour planes have been so influenced by the Neurological Plane through the constant Neurochemical and behavioural influences of the opioids, that simple medication is not enough. I have spoken to many former substance users whose longing is not for the drug, but for the lifestyle. It is about the excitement and chaos and sense of control over one’s feelings and being able to self-regulate on a whim. It is the using friends, the sense of rebellion and the easy means of coping that have all become expected and easily attained by drug use that hold a far stronger allure than mere physical dependence. These aspects will seldom be addressed by OST.
And so, in conclusion, I would say: Treatment treats dependence, and helps one disrupt the addictive cycle, recovery treats addiction and helps build the capacity to engage in life without illicit substance use, and in many cases both are needed to in varying degrees to reach the goal of a meaningful existence.This all brings as back to the first principle of addiction treatment: “There is no one-size fits all solution.”
