Lawyers, Libertarians, and Journalists On the Opioid Epidemic

It was a perfect confluence of events today.  At one point or another I heard or read about somebody's theory of why there was an opioid epidemic, deaths from drug use, and who was to blame.  Although some of the discussants were quite heated they all had one thing in common - they were all dead wrong.

Let me start with the lead story - the Attorney General of the State of Ohio suing drug manufacturers for the massive opioid problem in that state.  I say massive because there are an estimated 200,000 opioid users in the state and an associated mortality.  If you listen to the story (1) many local coroners and morgues are overwhelmed by the body count.  I heard the story on Minnesota Public Radio on the drive home tonight.  Ohio Attorney General Mike DeWine is suing Purdue Pharma, Johnson & Johnson, Teva Pharmaceuticals, Endo Health Solutions and Allergan for their role in the opioid epidemic.  Apparently the state of Mississippi filed the first law suit in the area.  The AG alleges that these companies basically convinced physicians through their questionable marketing efforts that these drugs were much safer than they really were and more effective for the conditions that they were supposed to treat.  Robert Siegel the reporter made an attempt to blame physicians instead and asked why they were not named in the law suit.  The AG's position was that the culture of medicine was affected by the false promotion and that it will take a while to change things around.  See the press release here for the exact position of the AG.  A copy of the entire complaint by the AG is available here.

The second story (2) came to my attention on my Facebook feed.  This was a case of  Ross Ulbricht - who was apparently convicted and sentenced to life in prison based on operating a darknet market that he created called Silk Road.  The conviction was apparently for money laundering, conspiracy to traffic narcotics, and computer hacking.  My interest in this case has nothing to do with the charges, the defendant himself, the conviction or the sentencing but the reaction on various web sites about the case.  There is a consensus on some of these web sites that he was offering valuable service for adults who want to come together and freely exchange items that it might be difficult for them to exchange in other places.  The associated arguments are that competent mature adults should be able to do this, that any interest the state has in suppressing such activity is an inappropriate intrusion on individual rights, and that in fact a service like this was essentially competing against cartels and may put them out of business. Some suggested that there was a conspiracy between the state and cartels to put sites like this out of business.  

All of these arguments fall flat to an addiction psychiatrist like me.  They seriously underestimate the effect that an addiction has on the brain and conscious state of an addicted individual.  Imagine what it is like to get out of bed in the morning and the very first conscious thought is: "How can I score some dope today so that I can function?" At that stage you are no longer a competent adult able to weigh decisions and make them in your best interest.  All of your decisions are weighted in the direction of ongoing drug use and addiction.  That is true if you are on the darknet looking for drugs or standing on a street corner in Ohio.  That is true if you are sitting in a physician's office and telling them what you think they need to hear to enable them to prescribe you more opioids.

The second aspect of opioid addiction that is difficult to understand is the genetic predisposition to addiction.  There are still a lot of pop psychology theories about addiction being just a bad habit or a lack of moral character that seem to explain the differences between people with addiction and people without addictions.  The fact is a substantial part of the population is genetically vulnerable to addiction and it is just a matter of whether or not they are exposed to a highly addictive drug.  If I had to estimate, my best guess would be that number is at least 40% of the population.  By that I mean that 40% of the population will get an extremely euphorigenic response to opioids (whether or not they work for pain).  They will remember that response and if exposed to more opioids are much more likely to use them than not use them.

That is what makes it so hard to stop this epidemic.  Without those two basic features of addiction there is no unlimited demand for addictive medications from pharmaceutical companies.  There is no need to go to a part of town that a person would never typically travel in to purchase diverted prescription opioids or heroin.  There is no need to search out opioids or other addictive drugs on the Internet or the dark net.

Doctors don't get off the hook.  All physicians are taught about controlled substances and the schedule of controlled substances.  All physicians know that opioids are scheduled according to their addictive potential.  The problem is that most physicians do not know how to interact with people who have significant addictions, and even experts can be fooled.  Most physicians have an incredibly naive approach to addiction and how they can prevent it or approach it once it is established. The cultural norm that physicians help people by prescribing them medications, combined with the fact that physicians are trained to help people, creates a powerful force to continue to prescribe addictive pain medications.  The absence of competent detox facilities is another.  

Pharmaceutical companies, doctors, judges and prosecutors - the pro and anti-blame rhetoric around this issue is intense and unrelenting.   It is not any easier to stop the current opioid epidemic when lawyers, libertarians, and reporters are spreading the blame around to anyone or anything other than the real cause of the problem - the addiction itself.

Start there - treat it as a public health problem and start to make progress.

A reminder about the Ross Ulbricht case.  I am not focused on the case per se or the War on Drugs.  I am solely focused on the argument that anything can be openly traded on a market between consenting adults.  I do not dispute the argument that the sentence was excessive or any other arguments for that matter.

Minnesota Street Drug Bulletin - Designer Benzodiazepines

Benzodiazepine structures clonazepam (upper left) and alprazolam (lower left) are both prescription benzodiazepines.  Clonazolam (upper right) and etizolam (lower right) are not. 

Designer benzodiazepines are benzodiazepine class drugs that are not approved for therapeutic use in any country.  They are analogues that were synthesized by drug companies, and in some cases went to clinical trials and published results but never made to to market.  The name makes is seem like there are chemists out there synthesizing these drugs for a purpose, but there are not.  They are all part of the original research for benzodiazepine class medications that has not really seen any innovation in decades.  These drug are a current problem because there are online sources allow people to purchase them in tablet, capsule, powder, and blotter form.  There are several online venues where users talk about their experience and which drug creates the "best" high.  Medical staff need to realize that many of these drugs are undetectable as molecules.  They show up as "false positives" in standard toxicology testing largely due to a lack of reference material.  Drug users are often told that the drug is undetectable in standard toxicology assessments and that the drugs are also not listed as a standard prohibited substance and therefore it is a "legal" high.  That is a fairly weak argument when users are overtly intoxicated and sustain all of the consequences of intoxication.

Just as a check I looked at a list of 13 designer benzodiazepines (1) (clonazolam, deschloroetizolam, diclazepam, estazolam, etizolam, flubromazepam, flubromazolam, flutazolam, 3-hydroxyphenazepam, meclonazepam, nifoxipam, phenazepam, and pyrazolam) and compared them to the most recent posted list of Controlled Substances from the DEA.  Only one of those compounds (estazolam) is listed on the most current list dated 05-May-17.  It is listed as a Schedule IV drug.  I have no way of knowing which compounds are being considered for the list.  Just being on the list does not deter the illegal sale of controlled substances, but the designer designation generally means that there is far less known about the drug in terms of safety.  In some cases the toxicology lags behind exposures because the physicians treating intoxication, withdrawal, and overdoses with these compounds are uncertain about what they are treating.  The patient or collateral contacts of the patient may not know what the drug is and that lag time creates additional danger for the patient.     

The first time I searched for clonazolam on Medline, I was impressed with the fact that there were only 5 references in the medical literature including the analysis reference that listed 13 designer benzodiazepines.  In fact, they all had to do with analysis but also described the complications of intoxicated driving (2) while taking them and the complications of life threatening intoxication (3).  The minimal online information available suggests that it has very high potency.  There are doses suggested in the range of high potency benzodiazepines but there are no clinical applications.  As a result, there are no FDA package inserts or even reliable data from other agencies.  It is not listed in the British National Formulary (bnf.org).  Despite this lack of clinical information and application, it is immediately obvious that large quantities are available for purchase online.  On these sites it is described as a research chemical with no clinical applications.  It is also described as not for human consumption - a label I am familiar with from synthetic cannabinoids.  The current problem is that as long as this chemical or its precursors are not listed as controlled substances anyone can purchase it for any purpose.  The suggested prices quoted for this drug are far below the street price of diverted prescription benzodiazepines.  That makes these compounds ideal for illegal trafficking.

Searching etizolam on Medline resulted in 96 references and 13 clinical trials.  Some of the trials were as recent as 2009.  The trials were for anxiety disorders and based on the abstracts the results sound equivocal ranging from improvement over 4 weeks to (4) to no improvement (5).  The striking feature of the trials is the dose of etizolam being 0.5 mg BID indicating that it is a high potency benzodiazepine.  The fact that several studies were done and the drug was never approved suggests either the lack of sufficiently powered studies or some side effect that was obvious only to the pharmaceutical company or regulators.  In some cases the drug is also too difficult to use clinically.  There are several examples of benzodiazepine class medications that were determined to be problematic after use and either banned at that point or an additional warning was issued.      

One of the more disturbing trends recently in the number of benzodiazepine compounds that are involved in polypharmacy overdoses.  In the most recent analysis of overdoses by the CDC -  2 of the top 10 compounds were alprazolam and diazepam - both prescription benzodiazepines. In both cases 95% of these overdoses involved concomitant drugs.  In the US, 30% of fatal opioid overdoses involve benzodiazepines. Due to the current problems with analysis, it is highly likely that designer benzodiazepines involved in overdose deaths are not detected. This is a compelling reason to not use designer benzodiazepines.  

Reading through some of the web sites that promote the use of these compounds, it is ironic that there are messages out that that these drugs can be used safely with adequate research by the user on the Internet.  Prescription medications are understood to have qualified safety when they are approved by the FDA and prescribed by a qualified physician.  There are still completely unanticipated reactions and these approved medications are not generally tested with other addictive compounds.  There are reactions that can only be detected by pharmacosurveillance of a much larger database.  In the case of these designer benzodiazepines, they are not approved, not prescribed, and highly potent drugs being sold by sources with no responsibility to the user.

Anyone seeking to get high in that context should be questioning the value of getting high.

Human Brain Performance Compared To Supercomputers

For about the past year, I have been using transversed edges per second (TEPS) in my lectures about neurobiology to give a rough estimate of the computing power of the human brain and a rougher estimate of where brain power compares with artificial intelligence (AI).  I finally found the detailed information on the AI Impacts web site and wanted to post it here, both for future reference and to possibly generate more interest in this topic for psychiatrists.

I have been interested in human computer comparisons since I gave a Grand Rounds on the topic back in the 1990s.  Back then I was very interested in bandwidth in the human brain and trying to calculate it.  My basic approach was to look at the major bus systems in the brain and their fiber counts and try to estimate how much information was passing down that bus.  In engineering terms a bus is a path that the computer or processors use to communicate with other devices or processors.  The rate at which that communication passes down that pathway is a major limitation in terms of computing speed to the rate at which tasks are transmitter to peripheral devices.  Engineers typically specify the characteristics of these communication paths.  A good example are the standard USB connectors on your computer.  Today there are USB 2.0 and USB 3.0 connectors.  The USB 2.0 devices can support a data transfer rate of 480 Mbps or 60 MBs.  The USB 3.0 connection supports 5 gbps or 640 MBs.

In the work I was doing in the 1990s, I looked at the major structures in the brain that I considered to be bus-like the fascicles and the corpus callosum.  Unfortunately there were not many fiber count estimates for these structures.  It turns out that very few neuroanatomists count fibers or neurons.  The ones who do are very exacting.  The second issue was the information transfer rate.  If fiber counts could be established was there any reliable estimate of the information contained in spikes.  I was fortunate at the time that a book came out that was somewhat acclaimed at the time called Spikes.  In it the authors, attempted to calculate the exact amount of information in these spikes.  They used a fast Fourier transform (FFT) methodology that I was familiar with from quantitative EEG (QEEG).  From available data t the time I was limited to calculating the bandwidth of the corpus callosum.  I used a fiber (axon) count of 200 million.  It turns out that the corpus callosum is a heterogeneous bus with about 160,000 very large fibers.  Using a bit rate of 300 bits/sec for each spiking neuron multiplied by the entire bus results in a total of 60 Gbs.  I had a preliminary calculation but realized I had about another 11 white matter fiber tracts connecting lobes, hemispheres and the limbic system.  I did not have the fiber counts for any of these structures and the top neuroanatomist in the world could not help me.

Then I found an interesting question posted in a coffee shop.  In the process of investigating it, I found some preliminary data about a group that was using a calculation called tranversed edges per second (TEPS) and showing at least on a preliminary basis that the human brain is currently calculating at a rate that is currently on par with supercomputers.  I found additional papers from the group, just this week.  The articles can be read and understood by anyone.  They are interesting to read to look at the authors basic assumptions as well as how they might be wrong.  They give rough estimates in some cases about how large the error might be if their assumptions are wrong.  They provide detailed references and footnotes for their assumptions and calculations.  

Their basic model assumes that the human brain is comprised of interconnected nodes in the same way that a supercomputer connects with processors or clusters of processors.  This basic pattern has been described in some situations in the brain but the details are hard to find.  There is also a question about the level for analysis of the nodes.  For example are large structures the best choice and if not how many smaller networks and nodes are relevant for the analysis.  In high performance computing (HPC) several bottlenecks are anticipated as nodes try to connect with one another including bus latency, bus length in some cases, and the smaller scale of any circuity delays on the processor.  The ability to scale or divide the signal without losing the signal across several pathways is also relevant.  For the purpose of their analysis, these authors use one of the estimated numbers of neurons in the brain (2 x 10¹¹).  The authors use a figure of 1.8-3.2 x 10¹⁴ synapses.  Division yields synaptic connections for each neuron at 3,600-6,400.

The TEPS benchmark is discussed in detail on the Graph 500 web site under 8.2 Performance Metrics (TEPS).  Reference 1 contains a more basic accessible definition as the "time required to perform a breadth first search of a large random graph requiring propagating information across every edge of the graph."  The information propagation is between nodes or nodes and memory locations.  The Graph 500 site also contains a listing of top performing supercomputer system and a description of their total number of processors and cores.  The rankings are all in billions of TEPS or GTEPS in terms of the performance benchmark with 216 systems ranked ranging from 0.0214748 to 38621.4 GTEPS.

For the human brain calculation, the authors use the conversion of TEPS = synapse-spikes/second = number of synapses in the brain x average spikes/second in neurons = 1.8-3.2 x 10¹⁴ x 0.1-2 = 0.18 - 6.4 x 10¹⁴ TEPS or 18 - 640 trillion TEPS.

What are the implications of these calculations?  If accurate, they do illustrate that human brain performance is limited by node to node communication like computers.  The AI researchers are not physicians, but it it obvious that taking more nodes or buses off line will progressively impact the computational aspects of the human brain.  We already know that happens at the microscopic level with progressive brain diseases and at the functional level with processes that directly affect brain metabolism but leave the neurons and synapses intact.  The original research in this area with early estimates was performed by researchers interested specifically in when computers would get to the computational level of the human brain.  Several of these researchers discuss the implications of this level of artificial intelligence and what it implies for the future.

For the purpose of my neurobiology lecture, my emphasis in on the fact that most people don't know that they have such a robust computational device in their head.  We tend to think that a robust memory is the mark of computation performance and ignore the fact that is why humans can match patterns faster than computers and comprehend context faster than computers.  We also have a green model that is more cost effective.

These are all great reasons for taking care of it.

Minnesota Street Drug Bulletin - Carfentanil

Opioids morphine (upper left) and hydrocodone (lower left) and synthetic opioids fentanyl (upper right) and carfentanil (lower right)

I don't know how widely known the issue with potent opioids  on the street is - but I am concerned that the information is not getting out to the people who need to hear it.  There are warnings that are read mostly by health care providers.  There are politicians talking about tougher penalties and legal approaches to solving the problem.  Like many people, I don't believe that the War on Drugs has been very successful.  At the same time, there are not many readily available options, there is a historical precedent for control of narcotics, and we will never know what the outcome might have been without legal action against illicit drugs.  I don't think that a failed War on Drugs means that there should be mass legalization of drugs.  The reason is obvious.  We are in the middle of an opioid epidemic that has been initiated and sustained by legal prescription opioids.  This epidemic says more about the nature of addiction than legal deterrents.  It is very clear that people with addictions will not hesitate to obtain what once were legally prescribed medications and use them.  It is very clear that designating legal addictive drugs does not reduce the black market for highly addictive drugs or create more tax revenues for governments - both common arguments for drug legalization.  All of these abstract arguments don't reflect what happens on the street.

I have personally talked with hundreds of opioid addicts over the course of my career.  In the 1980s and 1990s - there was a small population of users largely due to limited access.  Heroin and illicit opioid prices were relatively high and the barriers to use were also high.  Widespread exposure to opioids in high school was unheard of.  Most of the people I treated were part of a small, relatively fixed population of heroin users and some were on methadone maintenance.  That has all drastically changed in the last 15 years.

Now it is common for me to talk with young people in their 20s who were exposed to opioids when they got opioid prescriptions for injuries that used to be treated with ibuprofen or acetaminophen.  In some cases their peers in high school suggested they should try taking hydrocodone or oxycodone to get high.  In many cases those drugs were scavenged from unused medications in the family medicine cabinet.  Like many people in their teens and early 20s there is a cultural movement among users that they have a special body of knowledge about these drugs.  That reinforces drug taking behavior and keeps them in contact with people who are actively using and supplying these drugs.  In some cases it leads to mistakes in how the drugs are taken and what they are mixed with.  Drug users often have illusory relationships with drug dealers that makes it seem like these dealers care more about them than their friends and family do.  With continued and progressive use, opioid users might not notice how their judgment is more and more impaired - often to the point that they don't care if they die in the process of trying to get high.  To be clear, these people will deny any intent to harm themselves but get to a situation where they are using a questionable amount of drugs and realize it could be a problem but at that point they no longer care.  Heroin overdoses and deaths are common in small towns across America.  That was unheard of in the 20th century.

Against that backdrop - carfentanil has hit the streets in Minnesota.  Carfentanil is an extremely potent opioid that was never intended for therapeutic use in humans.  It is a large animal veterinary tranquilizer.  Its toxicity in humans is not disputed.  The most significant incident was the use of a gas that probably contained carfentanil in a hostage situation at the Dubrovka theatre in Moscow.  There were 40 Chechen rebels holding 912 hostages.  Russian security forces pumped in a gas that killed all of the rebels and 130 hostages.  The gas was described as a sleeping gas and later fentanyl.  Recent research suggests that the gas was a combination of carfentanil and remifentanil.  Some authors suggest that this was an anesthetic, but I have not been able to find any clinical application of this opioid in humans.  Potent opioids like fentanyl are used as anesthetic agents as well as pain medications.  

One of the ways that drug dealers amplify their profits is by taking a relatively inexpensive but potent product and diluting it down and selling the diluted product.  I have a previous post that shows how drug dealers can take $3800 of the synthetic cannabinoid AMB-FUBINACA and produce about a half million dollars worth of product containing about 64 mg of the original compound sprayed over shredded plant material.  I am not about to post how carfentanil can be diluted.  There are media reports that talk about how much more potent the drug is relative to both fentanyl and morphine.  Anyone trying to guess about how the raw drug can be cut is making a big mistake.  The amount of drug that can lead to a lethal overdose is so small that any non-uniform distribution in a powder or tablet can result in a lethal overdose.  The drug is so potent that even touching the powder can result in an overdose and health care workers have been warned not to touch the powder for that reason.

The problem is that carfentanil is being sold as a number of different products on the street. People are being given carfentanil as powders and tablets and being told that it is heroin, oxycodone, hydrocodone, and even benzodiazepines. This is an extremely dangerous practice and several Minnesotans have already died because of it.

Don't make the mistake of even trying opioids to get high. If you are currently addicted to opioids go to detox and get treatment. Don't make the mistake that you have another 5 or 10 years to get clean.  If you need to take opioids, get Medication Assisted Treatment with buprenorphine or methadone, rather than continuing to use what is available on the street.  With FDA approved medications used under a physician's supervision - you know exactly what you are getting.  The Minnesota Department of Health recommends education in overdose prevention and naloxone administration.

I can tell you that you can't trust what you are buying on the street.

But deep down you already know that.  Carfentanil is just another clear-cut example.

Luncheon Consensus - Management Continues To Do Nothing About Hospital Violence

I had lunch last weekend with staff from several psychiatric facilities in the Twin Cities.  The group included nurses, nurse practitioners, and health unit coordinators.  Many of them were at the retirement party that I described a couple of years ago.  At one point in time we all worked on the same inpatient unit and that was the common bond.  Over the several hour long lunch the discussion gravitated to one of our favorite topics - violence and aggression in hospitals against medical and nursing staff.  There was the usual litany of injuries - concussions, a stabbing, beatings, and musculoskeletal injuries.  At one point I heard how a staff nurse in her fifties with knee replacement surgery and back problems had to interject herself between a patient she was admitting and a violent and aggressive person who walked in off the street.  In that situation she had to hope that security got there in time to protect her.  I listened to another nurse tell me how the assault charges were determined after she was assaulted - first degree assault only because she had a concussion.  The other forms of being punched and kicked that she sustained that day were all lesser forms of assault.  I also heard how some members of the hospital administration minimized the incident and how her assailant eventually was not charged with anything.

This is one of many areas where the army of health care administrators really don't seem to be able to do anything productive.  Every hospital in the country has posted non-discrimination policies.  They discuss how every patient will be treated respectfully.  These same rules do not apply to their own staff.  When staff are assaulted there is a common belief that it is an occupational hazard.  It is all part of the job.  The other crucial part of the problem occurs at the committee level in higher levels of administration.  When ever there is a potential problem resulting in injury, a standard administrative strategy is to move it to a committee or Task Force.  That is where real problems occur because there is no expertise on the committee in assessing and resolving problems with violence in medical settings.  That lack of expertise is common.  A corollary is that administrators are in the position that they do not believe that they can defer to clinical staff with much more expertise because of the chain of command.  That is a recipe for inaction and manipulation.  If a staff person brings up a concern that the administrators can't solve - the issue is tabled or the person is not asked to come back.  Even more problematic, some administrators embark on their own ideas about how to solve the problem.  I have listed some instances of this happening on this blog that have resulted in more staff injuries.  A final strategy is to bring in consultants.  I have seen situations where expensive business consultants are brought in to either tell the staff that their patients are not any more aggressive than the patients seen in other hospitals in the state.  If that doesn't work - bring in a consultant who will try to demonstrate that he or she knows more than the current staff.  Both administrative strategies fall flat when the staff is dealing with some of the more significant problems with aggression in the state and they have the most experienced clinicians.

No - the violent outbreaks that are described in most hospitals are the result of administrative failures at several levels.  A failure to recognize the issue exists.  A failure to recognize that your staff has the expertise to deal with it.  A failure to recognize that aggression toward the staff is not the result of staff failing to treat people in a particular way or due to a deficiency of the staff person.  And most of all - a failure to facilitate a team approach among the staff in the hospital or clinic with the most expertise.  It is really that easy.

In our discussion, several instances of these manipulative responses to hospital violence were noted.  Even very basic requests for additional security staff and to prevent aggressive people from walking in off the street are ignored.  There is no shortage of meetings and I have participated in many.  One of the administrative strategies is blaming physicians for the problem.  There is nothing like having a dedicated and skilled staff with as much expertise as can be found anywhere - suddenly being blamed for the problem.  In some of these situations the administrators bring in "consultants" to tell senior clinics who have been treating the problem for 20 years.  I am speculating that is right out of "Power Plays 101" in administrator school.  It is not difficult to see how all of this administrative drama and expense fails to solve the problem.  In most cases it ends up looking like nobody is even trying.  A scapegoat has been found - let's leave it at that.

There has been a laudable effort by nurses.  In my home state, the Minnesota Nurses Association (MNA) has been very vocal in terms of the number of aggressive incidents toward nurses in Minnesota hospitals very year.  A 2004 study showed that that nurses were physically assaulted at a rate of 13.2 assaults per 100 persons per year.  17% of nurses were threatened and 34% were verbally abused in the preceding 12 months of the study.  The MNA has also been active to get legislation to legally protect nurses from aggression and assault.  This link to their proposal does not indicate whether either of their proposals have been successful.  

It appears that there are no comparable efforts by the state psychiatric association or medical association.  I am sure that if this luncheon group meets again, there will be reports of further injuries and a continued lack of response to the violence and aggression toward health care workers.

It probably makes sense in terms of the American inertia in dealing with violence and aggression in general.  But it also makes sense because health care administrators really don't do anything to support clinicians or improve the environment where they work.

Replacing all of those administrators is the best place to start.

Not Taking Antidepressants

I came across this open access article on my Twitter feed that highlights some of the reality of antidepressants that I was trying to get at in my previous post.  I encourage a full reading of the article in order to understand it - specifically how patients were selected from a large commercial database.  In this retrospective study the authors selected patient with a diagnosis of major depressive disorder (MDD) who were taking and antidepressant but only in a specific time interval.  They did this for the purpose of constructing the above survival curve.  They started with a group of 6,562,955 people on antidepressants between 7/1/2003 and 1/1/2014 and ended up excluding all but 527,907.  Exclusions were based on no diagnosis of MDD in the previous 6 months, no prescription of an AD in the previous 6 months, lack of continuous enrollment in the previous 6-12 months, and pharmacological  therapies that included initiating treatment with more than one AD or 3+ ADs or augmenting agents (AA).  The final study population was 527,907 patients.

Two major endpoints were defined as measures of medication adherence - medication possession ratio (MPR) and proportion of days covered (PDC).  PDC was considered the primary measure of adherence due to previous convention.  Calculations were made at 3, 6, 9, and 12 months.  Persistence and adherence were calculated for each major antidepressant class (SSRI, SNRI, TCA, MAOI, and Other).  Adherence and persistence were calculated across all of these dimensions.  Bar graphs are available in the full text.

Adherence and persistence at 6 months was 31-36%.  SNRIs had the highest persistence and adherence rates at 6 months at 37% and TCAs the lowest at 16-17%.  Looking at the Kaplan-Meier survival above the curves were significantly different with the lowest adherence to initial TCA and MAOI therapy.  The curves also show natural break points at 30 and 90 day intervals that correspond to the typical length of prescriptions although most primary care physicians provide a significant number of refills beyond that.

A study like this has obvious limitations and the authors do a good job of explaining them. Most of them had to do with the limitations of using a database like this one with limited granularity.  For example - no data about the status of the prescriber or practice context.  I would have the question of whether adherence was any different among those given and antidepressant based on a screening questionnaire versus more detailed assessment and follow up.  It would also be interesting to see if subjects seeing psychiatrists were any more adherent than than what I am guessing are the majority of patients being see in primary care.  Surrogate markers for psychiatric care could have been devised based on AD and AA combinations but that would be an imperfect marker since most primary care depression guidelines incorporate these strategies.   There was a very minor erratum (2) essentially a typographic error that does not change the main paper.                      

When I look at a study like this, I always ask myself if the study group resembles the people I am currently seeing or have seen.  In this case 64% of the population was female and 81% were covered by commercial insurance.  Twenty-four percent had comorbid anxiety, 24% had comorbid chronic noncancer pain, and 6% had both.  Sertraline has the largest percentage of prescriptions at 18.7% with only about 5.4% of people on bupropion extended release.  I currently see a large number of people on sertraline or citalopram +/- bupropion augmentation.  Despite the FDA warning about maximum doses of citalopram - I still see people on 60 mg/day or > 40 mg/day who are 62 years of age or older.  Both of those situations were flagged in the FDA warning.

I do find that SNRI medication are better tolerated than SSRI and do not hesitate to make that change sooner than later.

Give the limitations this is an interesting study.  At several levels it matches my experience.  At least 20-40% of people do not tolerate SSRIs very well.  I have also found that  SNRIs are effective and more well tolerated than SNRIs.  The major limitation from my perspective is that without the data that the authors refer to - it is really not possible to design a clinical program that optimized adherence or that provides much of a foundation for the differences.  Many psychiatrists have the experience that they see the same people with severe depression for years.  In many cases plasma levels of antidepressants are measure to optimize dosing but they also confirm adherence.  In other cases, the patients are in settings where medications are administered.  A critical dimension in psychiatric practice is the ongoing relationship with the patient.

Looking at how the relationship with the patient and how that effects adherence is needed, but it is obviously a more difficult study to capture in a retrospective database.

Burnout Industry Just Doesn't Get It

I was sent a long list of burnout interventions from a colleague today.  It was quite amazing.  Opinion pieces on Burnout. TED talks on burnout.  Books, videos, and web-based resources on burnout.  All with the message: "Physicians - in the event that you could not figure this out yourself - here is what you can do to alleviate burnout."   The disease model of burnout, except in this case we are not treating with with medication or surgery we are using life style modification.  What is wrong with this picture?

It turns out there is plenty wrong with this picture.  The biggest problem of course is that all of the factors that lead to burnout flow from incompetent management.  We have had a surplus of that in the past 30 years with no end in sight.  I would venture a guess that in all of my time in practice, I have seen about 1 manager who I would consider to be competent.  Nobody working for him was at risk for burnout.  More importantly, the most important protective factor against burnout has also become a casualty of bad management.  That factor is collegiality.  I could regale the reader with stories from my past on how much work I and my teammates did in various medical and surgical settings.  But I think that most people in working settings realize how much better the job and the day goes if they are working with bright, knowledgeable and highly motivated people.  A sense of humor is always a plus and I am convinced that at least some of the physicians I worked with were some of the funniest people I have met anywhere.

Rather than more stories, I will get right to the point about how bad management subverts collegiality.  Very early in the process, managers sold the idea that "there are some slackers in the group and therefore we need to introduce a way to measure productivity."  I was skeptical.  I looked around the room and did not see any slackers.  The statement appeals to those who are competitive by nature or anyone who wants to make sure that everyone is working as hard as they feel they are.  The next part of the process was adapting a very crude systems and after several missed starts applying it to everyone.  Even then I was quick to point out that it looked like 95% of the group was working hard and the only difference were the correction factors applied to the work units.  At that point I was told that this was not an academic exercise and we were now on this system whether I liked it or not.  Over the years, the calculations fluctuated and everybody did the same job, but now we were all cast as competitors rather than  colleagues.  In the end the productivity system was just a manipulation, more hoops to jump through as management made us less and less efficient with a series of roadblocks.

The second step is to set some arbitrary rules about how individual productivity affects the entire group.  In other words, penalize everyone up front and let the group know that this "holdback" in earned wages would be paid out only if everyone  made their productivity requirements.  I have never seen that rule applied to any other group of employees.

The next step is to set up some kind of arbitrary and meaningless employee evaluations.  Solicit random anonymous comments from any staff working with the physician employee and have them defend this one-sided criticism in their annual evaluation as if it is  true.  Have the physician who is working 60-70 hours a week, teaching, and doing independent educational activities select some goal at work that they will quickly forget until the next annual review.  All of the steps so far have served to isolate physicians and create a general paranoia about who might be making negative comments about them.  Paranoia is never good for collegiality.

Top this entire mess off with a primary school disciplinary system with a very low threshold.  Nurse Cratchett says that a physicians was too "curt" with her and suddenly that physician is called into the Chief of Staff's office and told that they are a disruptive physician.   Furthermore, that physician is advised that they have "one strike" against them and if they accumulate two more strikes they are "out".  There is no appeal process or due process.  If Nurse Cratchett complains - it must be legitimate and that conclusion based solely on the opinion of one person and supported by the Chief of Staff - stands.

At this point collegiality is gone and the physicians are further isolated from other non-physician staff.   Anyone can "report" them and that report will be taken seriously whether it is true or not.  The physician-administrators are no longer colleagues but hostile flunkies of the business hierarchy.

The final step was a stroke of genius by the incompetent managers.  For about 30 years managed care companies have had physicians reviewers sitting in a different state - remotely viewing records and telling the physician who is actually treating the patient - that patient must be discharged from the hospital or in some cases treatment for substance use disorders or outpatient psychiatric treatment.  In the last 10 years managers decided to have their own on site case managers, sitting in rounds and team meetings telling the physicians when to discharge patients.  If the physician doesn't go along with them they are reported to the medical director.  That creates additional problems and possibly another accusation of being a disruptive physician.

I have been talking about this sequence of events since I started writing this blog.  I recently encountered some resistance for the first time.  A colleague suggested that since burnout in physicians in other countries exists - there must be more to it than managed care.  I think that misses the point at a couple of levels.  First, it is possible that there are other bad managers - managed care companies certainly don't have a monopoly but they are highly standardized so that the onerous management practices that you find in one will certainly exist in another.  The literature on burnout in other cultures is small at this point and in some cases non-specific.  In other cases there is clear overlap.  But as I think more about this argument it seems lacking.  It seems like finding burnout and bad management practices in other countries can be used to rationalize the existence of ultimate bad management or managed care.  Secondly, bad management of personnel is just one aspect of bad management in general.  Does management ever do anything positive from an intellectual or creativity perspective?  Apart from one physician manager, I have not seen a single positive management outcome after observing a significant number of these people.

In fact,   if managed care administrators could not treat physicians like production workers they would have absolutely nothing going for themselves.  Nothing at all.
