POTUS Tweets Measures To Address Opioid Epidemic


I happened to be on Twitter last night when I caught the above Tweet from POTUS.  Having a professional interest, I decided to follow the link at the White House blog to look at the proposed measures.  They were listed as:

1.  Increasing a key drug for medication assisted treatment.  That key drug is buprenorphine in a number of formulations for treating severe opioid dependence.

2.  Preventing opioid overdose deaths.  This appears to be $11 million in funding for various forms of treatment and increasing access to naloxone to reverse the effects of an acute overdose.

3.  Addressing substance use disorder parity with other medical and surgical conditions.

These are very modest and in some cases unrealistic proposals about about trying to stop a drug epidemic that is killing 20,000 people a year.  Let me tell you why:



1.  Increasing a key drug for medication assisted treatment.  That key drug is buprenorphine in a number of formulations for treating severe opioid dependence.

Buprenorphine as Suboxone and Subutex have been available for the treatment of opioid addiction in the US since 2002.  The current evidence suggests that buprenorphine has superior efficacy for abstinence from opioids and retention in treatment.  There is also evidence that patients on buprenorphine have fewer side effects and that they is a less severe neonatal abstinence syndrome in mothers maintained on buprenorphine versus methadone.   Buprenorphine is also used for acute detoxification and treatment of chronic pain.  One of the limitations of maintaining opioid addicts on buprenorphine is that a special license is required to prescribe it.  Physicians can obtain that license by by attending CME or online courses.  Even then, expansion to primary care physicians has been slow because they may have no colleagues in their practice with similar certification and that makes on call coverage problematic.  In addition, many clinics that are medically based are reluctant to provide this type of service to people who have opioid addictions.  Apart from the technical requirements of prescribing the various preparations of buprenorphine certain physician and patient characteristics may also be important.  Physicians have to be neutral and not overreact in situations where the patient exhibits expected addictive behaviors that may include relapse.  As an example, younger opioid users are frequently ambivalent about quitting and in some cases, use other opioids and reserve the buprenorphine for when their usual supply dries up.  They may sell their buprenorphine prescription and purchase opioids off the street.  It may not be obvious but physicians prescribing this drug need an interpersonal strategy on how they are going to approach these problems.    On the patient side,  there is the biology of how the opioids have affected the person.  Do they have severe withdrawal and ongoing cravings?  What is their attitude about taking a medication on an intermediate or long term basis in order to treat treat the opiate addiction?

In clinical trials, buprenorphine seems to be ideal medication for medication assisted treatment (MAT) of opioid dependence.  Like most medications, there are issues in clinical practice that are not answered and possibly may never be answered.  The issue of life-long maintenance is one.  Many people with addictions are concerned over this prospect.  Long term maintenance with buprenorphine has advantages over methadone in that it is easier to get a prescription rather than show up in a clinic every day to get a dose of methadone.  Most addicts are aware of the fact that withdrawal from both compounds can be long and painful.  This deters some people from trying it and relapse risk is high if a person attempts to taper off of it.  Despite the current consensus about use. there is still the problem of young addicts who feel that they are "not done using" and who go between using heroin and other opioids obtained from non-medical sources and buprenorphine.  

2.  Preventing opioid overdose deaths.  This appears to be $11 million in funding for various forms of treatment and increasing access to naloxone to reverse the effects of an acute overdose.

Naloxone kits that would allow for rapid reversal of opioid overdoses have been shown to be effective in partially decreasing the death rate.  At some treatment and correctional facilities opioid users are discharged with naloxone kits for administration in the event of an overdose.  Opioids are dangerous drugs in overdose because they suppress respiration and that can lead to a cardiac arrest.  There are several properties of opioids that heighten the overdose risk.  Tolerance phenomena means that the user eventually becomes tolerant to the euphorigenic and in some cases therapeutic effects of opioids and needs to take more drug.  If tolerance is lost when the user is not taking high doses for a while, using that same high dose can result in an overdose.  Taking poorly characterized powders and unlabelled pills acquired from non-medical sources compounds the problem.  The exact quantity of opioid being used is frequently unknown.  Adulterants like fentanyl - a much more potent opioid can also lead to overdoses when users do not expect a more potent drug.

In addition to the pharmacology of the drugs being used there is also a psychological aspect to overdoses.  Users often get to the point where they don't really care how much they are using in order to get high.  They will say that they are not intentionally trying to overdose, but if it happens they don't care.

The available literature on making naloxone available suggests that it is effective for reversing overdoses in a fraction of the at risk population that it is given to.  I would see at as the equivalent of an Epi-pen in that the majority of patients with anaphylactic reactions get these pens refilled from year to year but never use them.  When they are required they are life-saving.  The problem with a naloxone kit is that it assumes a user or bystander can recognize an overdose and administer naloxone fast enough to reverse the effects of opioids before the user experiences serious consequences.  Unfortunately addiction often leads to social isolation and not having a person available makes monitoring for overdoses much more problematic.  Naloxone kits should always be available opioid users, first responders, family members, and anyone involved in assisting addicts.  Detailed long term data on the outcomes over time is needed.  


3.  Addressing substance use disorder parity with other medical and surgical conditions.

The is the most critical aspect of the President's tweet.  One of the main reasons for this blog is to point out how people with addictions and severe mental illnesses have been disproportionately rationed since the very first days of managed care - now about 35 years ago.  Some of the first major changes involved moving medical detoxification out of hospitals.  So-called social detoxification was available with no medical supervision.  These non-medical detox facilities were very unevenly distributed with only a small fraction of the counties in any state running them.  Any admissions to hospitals were brief and "managed" by managed care companies.  In the case of addictions some of the management practices were absurd.  A standard practice was to determine how many days a person could be in residential treatment.  That often required a call to an insurance company nurse or doctor who had never seen the patient.  They could determine that the patient could be discharged at any time based on arbitrary criteria.  In some cases that involved just a few days and the patient was leaving with active cravings and in some cases an an active psychiatric disorder.  This practice continues today, despite party legislation that suggests that addictions and mental disorders should be treated like any other medical problem.

This is where the President's tweet is on very shaky ground.  His legislation  focuses on large systems of health care and yet these systems don't seem to be able to supply adequate treatment with either buprenorphine or naloxone kits.  The President is fully aware of the The Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA).  That act was supposed to provide equal treatment for mental illnesses and addictions that was on par with medical and surgical conditions.  I think it is no secret that special interests have shredded the intent of this bill to the point that it is useless.  Managed care systems still ration care for these disorders in their best financial interest.  The resources for treating these disorders are still not equal to the task. In the case of prescription painkillers the same system of care not providing adequate treatment for addiction is often where that addiction started.

All three of the President's points could be addressed by forcing health care companies to provide adequate care for addictions and mental illnesses instead of grants to provide services that they should be doing in the first place.  In an interesting recent twist the President (1) suggested that this discrimination was based on race.  He implied that as a result the police rather than doctors have been used to address the problem.

Let me be the first to say that President Obama is wrong.  There is no doubt that racial discrimination exists.  There is no doubt that it occurs in systems of health care (2,3).  There is also no doubt that all it takes is a diagnosis of addiction or mental illness to trigger highly discriminatory health care coverage - irrespective of a person's race.  It is all about how health care businesses make money in this country by rationing or denying treatment for these disorders.

To reverse that discrimination,  the government needs to take the MHPAEA seriously.  So far they have failed miserably and that is the problem on the treatment side in trying to address the opioid epidemic.

Dr.Ghaemi on Dr. Spitzer






Nassir Ghaemi, MD has a commentary on Robert Spitzer, MD in this month's Clinical Psychiatry News.  After citing quotes by Shakespeare and John Adams to suggest that the dead are often idealized, he settles down to criticism based on whether or not the DSM-III helped or harmed the profession and Spitzer's role in that process.  Ghaemi comes down firmly on the side of harm because an unscientific approach to the diagnostic criteria for major depressive disorder has resulted in a lack of reliability and validity.  He uses the often quoted kappa score of 0.32 for diagnostic reliability of major depressive disorder in DSM-5 field trials as the main source of evidence, as well as the fact that the diagnostic criteria are unchanged since DSM-III.

Ghaemi suggests that his viewpoint is unique because unlike other eulogists, he had no personal connection with Spitzer and therefore can speak "in forthright recognition of fact from the impersonal perspective of another generation."  I am closer to Ghaemi's generation than Spitzer's and can make the same claim, but come to an entirely different set of conclusions.

I don't see Spitzer's efforts as being as corrosive as Ghaemi does, probably because I recognize the fact that there will never be a set of written diagnostic criteria that are perfect, based on science, and unambiguous.   But before I address the scientific, let me take on the rhetorical.  I would hardly blame Spitzer for the fact that the DSM criteria for depression have changed "hardly an iota" in the intervening 40 years since DSM-III.  Over that same time span there have been hundreds if not thousands of articles on the reliability of the major depressive episode diagnosis, as well as articles that analyze the symptoms according to that diagnosis.  There have been articles on standardizing various psychiatric and psychological instruments to detect major depression.  In fact, one of the rating scales basically copies the DSM criteria and asks the patient to rate on a 0 to 3 point scale - the percentage of days that they experience the symptoms. The PHQ-9 has become the standard for depression diagnosis in many primary care clinics.  There is also the fact that Spitzer's original DSM-III effort resulted in much higher reliability figures - a kappa of 0.72 to be exact (2).

There is also the issue that there have been two intervening Task Forces for DSM-IV and now DSM-5.   The Chair of the DSM-IV Task Force has since become a prominent critic of the DSM process and psychiatry in general.  I may have missed it, but at the time that Task Force was convened, I did not notice him or other members advocating for major changes to the major depression diagnostic criteria.  These are supposedly the top minds in the field.  Highly motivated academics with one axe or another to grind.  The idea that everyone would defer to Dr. Spitzer based on his original approximate efforts seems unrealistic to me.  More than a few people would have noticed his bungled and unscientific approach.

My major problem is using a single reliability figure as the grounds for this criticism.  Every year outpatient based psychiatrists can see up to a thousand new people a year.  They may find that up to 50% of those patients have had a life-long sleep disturbance.  Many can recall nightmares and sleep terrors as children.  Another 20-30% will have generalized anxiety or social anxiety since childhood.  In some there will be a performance based anxiety that is comorbid with the social anxiety.  Another 10-20% will have post-traumatic stress disorder to some degree.  About one-third will have a significant substance use problem.  These percentages will vary by clinic location and referral base.  The majority will be referred for a diagnosis and treatment recommendations for depression.  A substantial number of people with depression have comorbid anxiety and anxious temperaments.  I don't think it is a stretch to say that on any given day, many of the identified depressives will identify themselves as primarily anxious.  It is not unexpected to find that many patients don't really understand the difference between anxiety and depression or they will overtly say that they are the same problem - indistinguishable from one another.  Unless there is a clear differentiating factor like a manic episode, the postpartum state, or psychotic symptoms I would not expect that anxiety and depression are distinct disorders for most people.  At the minimum anxiety might morph into depression, but in most cases they are coexisting chronic conditions.  A low kappa in this situation should be expected and not a shock.

Does that mean that psychiatrists should be wringing their hands and blaming Spitzer for it?  Neither response is appropriate.  Psychiatrists are highly successful in diagnosing and treating mental illness, not because of a DSM manual, but because of clinical training.  When it comes to anxiety and depression there are no known ways to parse all of the symptomatic possibilities.  The human brain is designed to realize all of the possible combinations of human experience.  Why would we expect it to be different when it comes to experiencing anxiety and depression?  The only chance that a psychiatrist has to make sense of the world is a number of patterns of diagnoses based on their training and practice experience that they can match against the patient they are currently seeing.  These patterns guide the diagnosis and treatment plan.  A clinically astute psychiatrist is not plowing through the interview to see if the patient "meets criteria".  A clinically astute psychiatrist carefully attending to the patient's conscious state and trying to figure out how they can be helpful.  That includes figuring out the real problems and prioritizing them in a complex matrix psychiatric and medical problems.  None of that flows from the DSM and none of that resembles research based on lay people interviews using DSM criteria.

In closing, any commentary on Dr. Spitzer should include his role in eliminating homosexuality from the diagnostic manual.  This detail and how it occurred is never taught to residents.  I had to learn it from public radio many years after residency.  This detail is significant any way you cut it.  It invites criticism that monolithic psychiatry is currently moving too slow in other areas or that monolithic psychiatry was just responding to public pressure.  There is also criticism directed at Dr. Spitzer for a paper based on self report that was withdrawn years later on this same issue.  There are always advocacy groups seeking publicity by their own spin on the issue.   In my opinion, none of that diminishes that significant achievement that put psychiatry four decades ahead of most people in the United States.  Say what you will about the DSM, that accomplishment alone is enough.  I am thankful that Dr. Spitzer was open minded enough to listen to the advocates and eventually side with them.

Opiates And Moral Dilemmas For Physicians








I became aware of an article from Reason magazine written by a physician Jeffrey A. Singer titled Physicians Face A Moral Dilemma In Conscription on War on Drugs (1). In keeping with the main theme, the subtitle was “In the government’s new war on opiates, physicians and their patients find themselves caught in a crossfire.”  Physicians are generally in the crossfire of any number of government healthcare reforms. The opening lines of this essay should not surprise any physician.  We have been in the crosshairs for thirty years.  There is a tangible difference in the War on Drugs.  In the 1990s, I can recall a vague threat about incarceration for not doing my notes properly.  That wasn’t a threat to me specifically but an entire clinic of physicians than I belonged to at the time.  In retrospect it sounds absurd, but that the was pre-911 days when the FBI spent a lot of time reading physician notes and deciding whether or not they had committed health care fraud by not doing enough documentation.  These days physicians can be prosecuted and incarcerated for the way that they prescribe opiates. The threat is much more real.

Dr. Singer’s introductory paragraph points out that when any health crisis occurs politicians are eager to step up and offer their solutions and throw a lot of money at the problem.  In this case President Obama is building new drug addiction centers and “training” government physicians on opioids to the tune of $100 million.  Hillary Clinton is promising $10 billion as a criminal justice initiative as grant for drug treatment centers and training for first responders to administer opiate antidotes.  I have never seen a single politician or government bureaucrat acknowledge that the reason why the opiate epidemic exists has to do with policy initiatives that occurred right around the year 2000.  At that point, physicians were encouraged to treat pain more aggressively and with fewer checks and balances than they had in the past.  The cumulative effect of these policy changes was a lower threshold for prescribing opiates for chronic noncancer pain and a removal of some of the gatekeeper mechanisms – like getting second opinions from pain specialists on this practice.

The First War on Drugs was described as the initial prohibition of opiates and cocaine by the Harrison Act in 1914.  Singer describes a scenario where a physician who would prescribe an opiate to help a patient “cope with their addiction” as being in conflict with the law.  The Harrison Act prohibited physicians from prescribing opiates to maintain an addiction.  He cites this example as being the first moral dilemma.  It is more complicated than depicted.  There have always been a number of physicians who consciously or unconsciously maintained large numbers of patients in addiction and that was their medical practice.  That practice does not pass current conflict of interest considerations much less the ethical obligation of physicians to do no harm.  It is a given that legal interventions are generally blunt instruments for protecting people from their problematic decision-making and that a complete picture of all of the data (the number of people addicted by medical treatment versus non-medical sources) is never clear.  Is there a problem with suggesting that physician themselves should not be a primary source for creating and maintaining addiction?  The main problem is that even the most well-informed and well-intentioned physician can end up with a patient who is addicted to a medication.  There is currently no known way to prevent that.  Are those physicians criminals in any way?  I don’t think so.  At the same time, should there be a prohibition against physicians setting up a practice that maintains high number of patients in addiction, does nothing to facilitate their recovery from addiction, and has no other purpose – of course there should be such a prohibition. 

The next argument in the essay has to do with the safety of opiates versus alcohol.  This is a common argument by people who see nothing wrong with the legalization of drugs.  I am not suggesting that Singer is making this argument; he is trying to point out that opiates are relatively safer than alcohol and alcohol is a legal drug.  I think that he is wrong on several counts in this argument.  The first point has to do with the overall toxicity of alcohol.  He cites a number of diseases that have to do with the long-term toxicity of alcohol.  Alcoholic cirrhosis for example is typically the fifth or sixth leading cause of death in middle-aged men.  The estimated dose required in most cases is 15-pint years or drinking one pint of whiskey per day for 15 years (2).  Doing a quick calculation shows that this is about 143.26 grams of ethyl alcohol per day.  The progression to cirrhosis will vary based on sex, genetic factors, and rates of metabolism.  The overriding point is that alcohol consumption at this rate is limited to a small percentage of drinkers and the population exposure to alcohol is relatively stable based on current legal and cultural factors.  A related issue is that if you are alcohol dependent tolerance and withdrawal phenomena may lead to a marked increase in consumption – up to 750-1,500 ml/day in order to maintain blood levels high enough throughout the day to prevent withdrawal.  The exposure of multiple tissues over time causes the damage.

The primary mechanism of injury and death from opiates is respiratory ataxia and arrest by the direct action of the drug on small clusters of cells in the midbrain and medulla.  Opiates have a direct effect on the center that determines respiratory rhythm and the center that responds to chemical changes due to oxygen deficiency and carbon dioxide accumulation.  Benzodiazepines, alcohol and sleep medications are often involved in these situations and have a combined effect.  Alcohol in high enough doses can have a similar effect in depending on the individual and their state of tolerance.

Looking at the acute mortality related to alcohol and opiates, I don’t think that there should be any doubt that opiates are probably more lethal than alcohol.  The CDC states that about 2,200 people die every year from acute alcohol poisoning (3).  The population at risk appears top be 38 million binge drinkers.  Men ages 35-64 are at highest risk.  In 2014, there were 18,893 overdose deaths from prescription painkillers and 10,574 deaths from heroin overdose (4).  In this case the estimated populations at risk include 1.9 million people with a prescription painkiller problem and 586,000 heroin users.  Furthermore the death rate from prescription painkiller and heroin use parallels the availability.  I am puzzled by the author’s suggestion that opiates are “much safer” and that there is “honest disagreement among health care practitioners over just how harmful long term opiate use can be…”.

I guess that I am one of those disagreeable health care practitioners.  Anyone can fact check the above argument for acute toxicity and I would encourage a close look at the trendlines over the past 15 years.  If you look at this lines, you will find that the rate of deaths due to heroin overdose was relatively stable for at least a decade before a sizable number of prescription painkiller users decided to start using heroin.  The decision is a strictly economic one.  The most commonly abused prescription painkiller costs a dollar per milligram on the street.  Addicts are typically using 120-240 mg per day.  The equivalent amount of heroin can be purchased for about ¼ as much.  The end result is that stable rate of heroin overdose deaths has quadrupled in the last 5 years.  It is stark to contemplate that the total opiate death rate is based on a population at risk that is about 10% the size of the drinking population at risk.

Dr. Singer describes the movement that led to increased opiate prescribing at the beginning of the 21st century as “enlightened” and “compassionate.”  He uses the term opiophobia as the irrational fear that doctors and patients have about these medications.  I think it is very clear that these advocacy groups and bureaucrats had no clue that increased access would lead to an epidemic of addiction and overdose deaths.  The moral dilemma for physicians is not colluding with law enforcement in the War on Drugs and “cutting patients off.”  The moral dilemma is practicing sound medicine in a system that blames them for not prescribing enough opioids and then ten years later blames them for prescribing too many.  All of this occurs against the backdrop of a culture that has an insatiable appetite for intoxicants in a country that has one of the highest per capita opiate consumption rates in the world.  The moral dilemma for physicians is recognizing that they can’t predict who will or not become addicted to an opiate and that many physicians do not have the skills necessary to not prescribe to patients who either really don’t need the drug or are probably addicted to it.

There is more than one moral dilemma in the opiate epidemic.  On the patient side should you let your doctor know if you have an addiction before the opiate prescription is written?  Should you let your doctor know that the first pill from the prescription left you feeling euphoric, energetic, confident and like you have never felt before in your life?  Should you let your doctor know that you are continuing to take prescription painkillers even though they don’t work for the pain or because the pain is gone?  Should you tell your doctor or pharmacist know that you suddenly have access to all of the opiates from a deceased family member who was in hospice care and ask how to keep them off the street?

There are many moral dilemmas associated with opiates for everyone and very little moral guidance.

Supplementary:

To calculate the mg alcohol in a pint of whiskey:

1 pint = 473.18 ml

473.18 ml x 0.4 (percent alcohol) x 0.757 g/ml (specific gravity of alcohol) = 143.26 g ethyl alcohol

The Screeners - Annotated: Psychiatric Lessons From A Short Science Fiction Story




I recommend reading the original version (preceding post) first before reading the annotated version.


What follows actually happened in the year 2066......

I could tell my brother needed help. We had been underground for too long. Whenever that happened he stopped sleeping regularly, he started to act crazy. This time he was looking for footprints - evidence that somebody was trying to get in through the hatch. I explained to him that the hatch was hydraulically locked from the inside. It was designed to take a direct hit from a grenade-launcher. But who could even hit it at that angle, flat against the two foot thick concrete roof of our bunker. This time he was sprinkling flour rations on the floor under the hatch. Anyone who came in had to step on that area and he would have their footprint in the flour.

This is an almost universal experience of family members directly observing their relatives with bipolar disorder.  They notice they become unpredictable sometimes to the point that they are frightening.  This is often manifested in their capacity for rational thought and personality changes.  In this case they observe paranoid behavior - defined as an unrealistic fear of harm or manipulation.  Family members are often at a loss in this situation because the person with the problem denies that there is anything wrong.  In many cases, the personality changes go on for months and lead to problems with employers and spouses.   

But the powder around the entrance was the least of our worries. His apartment was within a hundred feet of the hatch. He sat in his apartment looking out the window. He kept a plasma cutter nearby. It was for self defense, but he also told my son that if anyone did breach the hatch and they came for him - he knew exactly what to do. He would turn the plasma cutter on himself. He did not want to give the invaders a chance to torture and kill him. He would kill himself first. It would be over quickly.

This is a little known form of suicidal thinking that occurs in paranoid people.  They are so fearful of the unknown assailants that they are prepared to kill themselves - rather than be tortured or slowly killed.  In fact, they are not in danger at all.  This problem requires an intense effort to diagnose and treat - independent of any medications.

He had been getting worse for the past ten years. Long periods of laying in bed for days and weeks, barely eating and drinking. Not saying a word. That usually happened after weeks or months of being hyper, talkative and staying up all night. If you caught him at exactly the right time, he was interesting, funny, and you felt good talking with him. At the wrong time - it could be a nightmare. He could accuse you of trying to steal his American Gold Eagles. Everybody knew he had a tube of them somewhere in the bunker. Everybody knew because whenever he got hyper and started talking a lot, he would hold some of the coins in his hands and show everybody that he had them. During one of these episodes, he gave a couple of them away. Gold Eagles worth tens of thousands of dollars - just handed out to strangers at a watering hole.

Very typical behavior of untreated bipolar patients.  During periods of hyperactivity and euphoria they may give away large sums of money to casual acquaintances without being able to assess the consequences.  This can lead to financial duress or in the extreme, financial ruin. 

He had bipolar disorder, just like our mother. He has never seen a doctor, I just know from my experience with my mother. I remember going to see the doctor with her. She would see her every couple of months, unless she was having problems and then it would be more frequently. She liked that doctor and trusted her. She would always tell me that if she got too sick to make it to the doctor, my job was to call the doctor's office and let her know that she was not doing well. The doctor came over to our house one day to see my mother. Mom didn't say much, but the doctor knew what she needed and a short time later she was better. That went on like that for about ten years until I was ready to go to college. That was when the Supervolcano blew and we all had to go underground for three years. Mom was 60 by then. She couldn't adapt to living underground. She could not sleep underground in the phosphorescent lighting. She would stay up for weeks and get harder and harder to understand. She would start swearing and eventually made no sense at all. Then she would crash and not be able to eat. My wife and I would encourage her, but she would say: "Let me die....pick up that knife over there and kill me." We knew that she was not joking. Until the air finally cleared, there were no doctors and no medicines. She only had a month of medication when we went underground. Nobody could get more than a month at a time - even though everybody knew it was going to be a long time before we could come up for air.

Bipolar disorder definitely runs in families with what appears to be sporadic inheritance because of the polygenic nature of the disorder.  Bipolar disorder is sensitive to sleep and circadian rhythm disruptions and patients need to be counseled and constantly reminded about this.  Severe cognitive problems and catatonia can result and lead to severe disability. 

At about the one year mark - Mom died. She just got more and more confused. She stayed in bed and did not eat or drink anything for five days. The paramedic in our bunker said that she probably died from dehydration.

I don't think it is common knowledge that bipolar disorder can be a fatal condition.  At the turn of the 19th century, well before there were any useful medications - some forms of bipolar disorder were highly fatal.  Estimates from Boston Hospitals at around that time suggested that malignant catatonia resulted in about an 80% fatality rate.  Untreated mania in those days also resulted in a significant number of deaths from congestive heart failure due to constant agitation.  These facts are often ignored during an era where even episodic care during exacerbations of illness can prevent death.  Inpatient psychiatrists and consultation-liaison psychiatrists still find themselves in many life and death situations per year with hospitalized patients on the verge of dehydration and starvation due to severe psychiatric disorders.  In many situations, one of the best treatments available for this problem - electroconvulsive therapy is unavailable due to legal and political constraints.   

"Kevin is getting bad again" - my wife walked in. She was wearing standard desert camouflage hardened to withstand all of the fly ash. "I just saw him. He had melted a jar of peanut butter in the microwave and and he was throwing it all over the place. He has it splattered all over the walls. It looks like a Jackson Pollock painting." My wife was going to study art before the Supervolcano or "SV" as some call it now. Most people just talk about surviving it by using the phrase "when the air cleared." "We have to do something before he ends up like your mom or somebody takes advantage of him and gets his gold."

Highlights the familiy predicament of dealing with a family member who has had a transformation of their conscious state.  They are no longer predictable or rational.  Most emergency medical personnel confronted with this situation would ask the person a few questions and leave.  If the person became verbally aggressive, the outcome of the situation is highly dependent on the skill of the emergency personnel or involved law enforcement officers and there can be very adverse outcomes.

"More like hitting him over the head and taking it you mean. You would think that a guy who can be that paranoid would not put himself in those situations." I knew the words were meaningless as soon as they rolled off my lips. I had been watching bipolar people in my family for decades and they are unpredictable. Expect to see them in a certain situation and they disappear for weeks or months. "We have to try to get him to Minneapolis and see if they have scavenged any medication or if any new medical supplies have been flown in."

We had been to Minneapolis a couple of times since the air cleared. The trip is not too bad - 300 miles by a skimmer across the fly ash. So far nothing was growing up through the fly ash. We make good time with a skimmer and the metal composite tires make that trip many times before they need to be replaced. It just takes 20 minutes to recharge the batteries and we are back home the same day. The medical infrastructure was slowly being rebuilt. Practically all of the health care administration in the state was in Minneapolis and many of these bureaucrats survived the near extinction event. Surgical services and Cardiology had been restored. Last year they began doing heart, lung, liver and pancreas transplants at what used to be University Hospital.

There is a long history of discrimination against psychiatric and addiction services, despite the fact that they are routinely assessed as being in the top 10 disabling conditions world wide.  The discrimination is well documented on this blog and it occurs at all levels.  The so-called critics of psychiatry do not mention this phenomenon because it is inconsistent with their view that psychiatry is the source of all problems and not the selective rationing.

Treatment for mental disorders was always a problem. As people started coming out of their bunkers and heading back into the city general medical care was available in many places. The only treatment for mental disorders occurred in the same clinics where people went to get treated for infections and lung problems from the fly ash. People still got cancer and heart disease. People still got involved in accidents and injured themselves. Doctors with various skills were still around even though training programs were just restarting. Doctors tended to be old or really young.

In this piece, collaborative care and its ultimate goal of eliminating psychiatry rules the day.  An interesting proposition is who all of the critics will blame when psychiatrists are gone.  The obvious choice would be the next batch of prescribers, but in my story they became history as well.  There is clear history of mismanagement in medicine - rationalized by "cost effectiveness".  The most cost effective approach is to marginalize all professionals and pretend to replace them with checklists or artificial intelligence

My wife and I did some fast talking, convinced Kevin it would be an exciting trip, loaded him in the skimmer and took off. Within 4 hours we were standing in line in a large warehouse that had been converted to a medical clinic. Half an hour later we were face to face with a triage person:

"Nature of the problem?" he said matter of factly.
"My brother has bipolar disorder and he needs treatment." I replied.
"We don't see a lot of that here, are you sure about the diagnosis?" The triage person seemed a little impatient.
"My mother had it and she told me that her grandfather had it. He does a lot of what she used to do. His whole personality changes at times and he has problems taking care of himself. She used to see a doctor who treated bipolar disorder. Do you have a doctor like that?"
"Not anymore...but we do have screeners."

You don't have to live in the year 2066 to experience the above dialogue.  It is occurring right now in hundreds of clinics across America.  No access to psychiatrists or mental health professionals who could be very useful in treating the problems that they were trained to treat. 

We walked to the west side of the warehouse and entered a small room. There were a few people there. We got in to see the screener in a about 20 minutes. He looked like a clone of the triage person right down to the American Health Care pin on his lapel. He listened to me describe the problem for about two or three minutes, reached in a drawer and pulled out a piece of paper. It had three questions on it. After every question there was a line that varied from "None" to "Most of the time." Kevin made three checkmarks - one on each line at about the 75% mark.

This is a standard approach being used right now.  A checklist will be made right out of the DSM criteria.  Then it will be pared down to 3 or even 1 question rating scales.  Without the presence of a diagnostician, the checklist score and cutoff becomes the default diagnosis.  The interesting aspect of a screening instrument for bipolar disorder is that in many cases the affected person will not endorse any problems on the scale even when they are quite symptomatic.  

"Well he qualifies for treatment." the screener remarked. "The Army just brought in a shipment of medication for mood problems."
"My mother used to take Phosphotide 23, before the volcano blew. It worked pretty well."
"No ... all I have is this stuff.   It is taking a while to get drug manufacturing up and running again. Only the west coast facilities were untouched and they have shifted all of their production to what people really need...you know antibiotics, heart meds, asthma medication. But I have plenty of this medication. Give it a try. Take two of these tablets every night".

There are widespread complaints about Big Pharma and medication prices.  I have written several pieces on this blog myself.  Medication expenditures have created a large number of medications and a significant surplus, but they are ironically rationed by Pharmacy Benefit Managers and managed care companies, even to the point that generics drugs require a negotiation.  In this case the patient is being given a medication that is probably not indicated for his condition and may make him worse.  Similar problems can occur with treatment based on screening tests.   

He handed me a large bottle of medication. The darkened label on the bottle read: "amitriptyline 25 mg tabs". The expiration date was July 20, 2025. I looked back at the screener and asked: "Is there anybody he can talk to about some of his problems? He goes off on a tangent and my wife and I don't know what to say to him."

This is a current problem in the business oriented behavioral health system.  Psychotherapy is rationed and in many case therapists have productivity expectations that they cannot sustain and that leads them to quit.  Contrary to popular myths people with severe mental illnesses benefit greatly from talking with their psychiatrists and are often reluctant to see other therapists or physicians.  In many systems of care today patients with severe mental illness see a "prescriber" for 15-20 minutes - 2 - 4 times a year. 

"No I'm afraid not. At American Health Care we do screening. My understanding is that the new government and the remaining businesses got together and decided that was the most cost-effective approach."

"Cost-effective" is a buzzword that is unevenly applied.  That should be evident from comparing psychiatric services (or behavioral health services) to every other medical specialty in any health care system.  There is a sharp contrast between what this concerned family member knows about bipolar disorder (disabling and killing his mother and disabling his brother and making him unpredictable) and how the health care system responds to his concerns.  It is as if  he is talking about a trivial condition.

Within thirty minutes we were back in the skimmer, moving at good speed across the fly ash. I glanced over at my wife. Her large blue mirrored-out glacier glasses did not conceal her worry. I looked at the plume we were kicking up in my rearview screen and thought:

"I hope this works."

Our concerned family member here is hopeful, but it is highly unlikely that the medication he picked up will be effective and it may make the situation worse.  The patient and family would have benefited by a detailed risk-benefit and monitoring discussion, as well as a follow-up plan.  In a typical screening procedure that occurs today, a person may leave the office with one or more month-long prescriptions and no clear plan for monitoring or contingencies if the medication does not work or it is not tolerated.  Follow up periods are frequently too long to make much of a difference and many people either discard the medication immediately, don't get it refilled, or get side effects - don't report them and discard the medication.  More frequent meetings for psychotherapy or closer monitoring are the exception rather than the rule.  

The more I thought about this near apocalyptic science fiction story, the more I realized that this is the type of care that many (if not most) people get right now and it is the type of care that is being promoted over seeing psychiatrists.

The Screeners





What follows actually happened in the year 2066......

I could tell my brother needed help.  We had been underground for too long.  Whenever that happened he stopped sleeping regularly.  He started to act crazy.  This time he was looking for footprints - evidence that somebody was trying to get in through the hatch.  I explained to him that the hatch was hydraulically locked from the inside.  It was designed to take a direct hit from a grenade-launcher.  But who could even hit it at that angle, flat against the two foot thick concrete roof of our bunker.  This time he was sprinkling flour rations on the floor under the hatch.  Anyone who came in had to step on that area and he would have their footprint in the flour.

But the powder around the entrance was the least of our worries.  His apartment was within a hundred feet of the hatch.  He sat in his apartment looking out the window.  He kept a plasma cutter nearby.  It was for self defense, but he also told my son that if anyone did breach the hatch and they came for him - he knew exactly what to do.  He would turn the plasma cutter on himself.  He did not want to give the invaders a chance to torture and kill him.  He would kill himself first.  It would be over quickly.

He had been getting worse for the past ten years.  Long periods of laying in bed for days and weeks, barely eating and drinking.  Not saying a word.  That usually happened after weeks or months of being hyper, talkative and staying up all night.  If you caught him at exactly the right time, he was interesting, funny, and you felt good talking with him.  At the wrong time - it could be a nightmare.  He could accuse you of trying to steal his American Gold Eagles.  Everybody knew he had a tube of them somewhere in the bunker.  Everybody knew because whenever he got hyper and started talking a lot, he would hold some of the coins in his hands and show everybody that he had them.  During one of these episodes, he gave a couple of them away.  Gold Eagles worth tens of thousands of dollars - just handed out to strangers at a watering hole.

He had bipolar disorder, just like our mother.  He has never seen a doctor, I just know from my experience with my mother.  I remember going to see the doctor with her.  She would see her every couple of months, unless she was having problems and then it would be more frequently.  She liked that doctor and trusted her.  She would always tell me that if she got too sick to make it to the doctor, my job was to call the doctor's office and let her know that she was not doing well.  The doctor came over to our house one day to see my mother.  Mom didn't say much, but the doctor knew what she needed and a short time later she was better.  That went on like that for about ten years until I was ready to go to college.  That was when the Supervolcano blew and we all had to go underground for three years.  Mom was 60 by then.  She couldn't adapt to living underground.  She could not sleep underground in the phosphorescent lighting.  She would stay up for weeks and get harder and harder to understand.  She would start swearing and eventually made no sense at all.  Then she would crash and not be able to eat.  My wife and I would encourage her, but she would say: "Let me die....pick up that knife over there and kill me."  We knew that she was not joking.  Until the air finally cleared, there were no doctors and no medicines.  She only had a month of medication when we went underground.  Nobody could get more than a month at a time - even though everybody knew it was going to be a long time before we could come up for air.

At about the one year mark - Mom died.  She just got more and more confused.  She stayed in bed and did not eat or drink anything for five days.  The paramedic in our bunker said that she probably died from dehydration.

"Kevin is getting bad again" - my wife walked in.  She was wearing standard desert camouflage hardened to withstand all of the fly ash.  "I just saw him.  He had melted a jar of peanut butter in the microwave and and he was throwing it all over the place.  He has it splattered all over the walls.  It looks like a Jackson Pollock painting."  My wife was going to study art before the Supervolcano or "SV" as some call it now.  Most people just talk about surviving it by using the phrase "when the air cleared."  "We have to do something before he ends up like your mom or somebody takes advantage of him and gets his gold."

"More like hitting him over the head and taking it you mean.  You would think that a guy who can be that paranoid would not put himself in those situations."  I knew the words were meaningless as soon as they rolled off my lips.  I had been watching bipolar people in my family for decades and they are unpredictable.  Expect to see them in a certain situation and they disappear for weeks or months.  "We have to try to get him to Minneapolis and see if they have scavenged any medication or if any new medical supplies have been flown in."

We had been to Minneapolis a couple of times since the air cleared.  The trip is not too bad - 300 miles by a skimmer across the fly ash.  So far nothing was growing up through the fly ash.  We make good time with a skimmer and the metal composite tires make that trip many times before they need to be replaced.  It just takes 20 minutes to recharge the batteries and we are back home the same day.  The medical infrastructure was slowly being rebuilt.  Practically all of the health care administration in the state was in Minneapolis and many of these bureaucrats survived the near extinction event.  Surgical services and Cardiology had been restored.  Last year they began doing heart, lung, liver and pancreas transplants at what used to be University Hospital.

Treatment for mental disorders was always a problem.  As people started coming out of their bunkers and heading back into the city general medical care was available in many places.  The only treatment for mental disorders occurred in the same clinics where people went to get treated for infections and lung problems from the fly ash.  People still got cancer and heart disease.  People still got involved in accidents and injured themselves.  Doctors with various skills were still around even though training programs were just restarting.  Doctors tended to be old or really young.

Baseball Caps, Wrap-Around Shades, and Sunglass Theory



I saw Erik van Kuijk MD, PhD present a lecture on macular degeneration at the Minnesota Academy of Medicine a couple of weeks ago.  He is an international expert in the subject and thoroughly reviewed the epidemiology,  basic science and current treatment of the disorder.  He described the risk factors including age (>60 years), smoking (doubles the risk), dietary factors (antioxidants) and sun exposure.  He  suggested the best barrier methods for sun exposure included baseball caps and wrap-around sunglasses.  At that point during the lecture, I had a brief episode of free association about that remark and thought about the sunglasses issue.   Within a few minutes I thought about sunglasses and their multiple roles in society.

To some sunglasses are a projective test.  I recall a college professor who seemed eager to tell anyone who would listen that men who had beards and sunglasses "had something to hide."  I had both, but could have told him that (being an introvert) of course I had something to hide, but it really had nothing to do with the beard and sunglasses.  Sunglasses can have special meaning with some psychiatric disorders that tend to magnify ordinary thoughts like - "These sunglasses make me look like an alien.  I might want to look like an alien."  You don't have to have a psychiatric disorder to have that thought.  Eye contact and facial expression depends a lot on the eyes and there are some people who realize this and do not want to expose that channel of communication.  On inpatient psychiatric units sunglasses are usually forbidden and rationales vary from place to place.  There are typically other patients and staff who are intimidated by people wearing sunglasses.  I was in a meeting at one point where one of the participants asked a late arrival about sunglasses because they were "freaking her out".  There are a couple of books out there that look at the social meaning of sunglasses both in terms of social behavior and fashion.  The scope of these books is discussed in the popular press largely in terms of why people with sunglasses may be more attractive.  The medical literature has surprisingly little to say about these factors. Indirectly there has been some work on facial symmetry as an attractive feature, and speculation that in some cases sunglasses give the appearance of greater facial symmetry.

As a cyclist, sunglasses have a prominent place in cycling literature.  Coaches typically advise eye protection for a number of reasons, but the best articulated one is to reduce fatigue.  If you are training and cycling tens to hundreds of miles per day, in most places you are going to be cycling into the sun at some point.  Without sunglasses there is a reflexive squint that eventually spreads to facial, neck, shoulder, back and chest muscles.  It would not surprise me that this also results in increased grip tension on the handlebars and that can increase blood pressure.  All of that muscle contraction leads to increased fatigue and decreased efficiency.  These factors probably explain why so many professional cyclists have shades and that they are some of the best designed wraparounds on the market.  Epidemiological studies also show that total sun exposure is a risk factor for macular degeneration and skin cancer.  That places certain occupations and recreational pastimes at higher risk.  A sampling of beach goers in Spain showed that there was no correlation between the subjects who sustained sunburns and whether they used adequate skin or eye protection.

Eye protection to prevent cataracts and macular degeneration is the most important application of sunglasses.  Ultraviolet light is to toxic factor and a recent review shows correlations with a significant number of eye diseases including eyelid malignancies, cataracts, photokeratitis, pterygium, and more limited data for other eye diseases (7).  As the eye ages, natural changes make it more susceptible to damage from UV light.  The literature from the National Eye Institute emphasizes that avoiding smoking, exercising regularly, blood pressure control, maintaining a low cholesterol, and eating a diet high in antioxidants and fish are the best preventive measures.  Sunglasses are not listed, but they were factored into the lecture I attended and many research articles. The dietary recommendations are based on trials of nutritional supplements used in the Age Related Eye Disease Study (AREDS-1 and AREDS-2).  In these studies, patients were recruited with early macular degeneration and were followed for progressive visual loss.  The formulation decreased the rate of progression of the eye disease.  The formulation in AREDS-2 consisted of lutein, xeaxanthin, Vitamin C, Vitamin E, zinc, and copper.  

The photobiology of light hitting the retina and macula is important in the development of macular degeneration.  The UV spectrum is typically broken up into UVA (320-400 nm), UVB (280-320 nm), and UVC (< 280 nm).  Only the first two are important since UVC is blocked by the ozone layer.  UVA has the deepest skin penetration and has been shown to generate reactive oxygen species (ROS) like singlet oxygen and hydrogen peroxide.(8)  Peroxiredoxins may be a significant defense against free radicals cause by UV light hitting eye structures.  Peroxiredoxin-3 (Prdx-3) is in the retina and lens of the eye.  In the  retina it is highly expressed in areas where there is high mitochondrial density.  The chemistry of lutein and xeaxanthin and their proposed role in preventing damage is interesting.  Both are 40 carbon conjugated compounds.  They absorb light at the 400 -500 nm range just outside of UV.  One of the ways that UV causes damage is by creating reactive oxygen species (ROS) when it hits susceptible structures in tissue.  The eye becomes more susceptible to UV damage as the chemical composition of chromophores in the eye change with aging.  As UV light hits phototoxic chromophores in the eye producing free radicals and singlet oxygen.  That in turn leads to photooxidation and damage to the eye.  Lutein and zeaxanthin act by quenching these ROS (11).  

Lutein
Zeaxanthin

What are the implications for psychiatrists in all of this?  The first is smoking cessation.  Smoking is a public health problem on its own and nicotine exposure is probably a gateway to further drug use with recent convincing work done on the epigenetic mechanism.  Macular degeneration is just another reason to advise people to not smoke.  The healthy diet and exercise proposed here for ophthalmology patients is another way of saying, avoid obesity and the metabolic syndrome.  Psychiatrists need to be giving their patients the same advice about diet and exercise.  Metabolic syndrome is a significant comorbidity, precursor, and iatrogenic complication of mental illness.  Some theorists have suggested that ROS produced in metabolic syndrome is a reason for the numerous complications.  Another potential research area is whether or not any current medications prescribed by psychiatrists increase the likelihood of cataracts, macular degeneration, or directly affect some of the phototoxic mechanisms that can occur in the eye.  I can recall that as a medical student we emphasized eye exams on psychiatric patients and there was a brief emphasis again when quetiapine was initially marketed, but not much evidence since.  In those days we were concerned about stellate cataracts and retinal hyperpigmentation caused by phenothiazines.  With the institutionalized deterioration in the quality of psychiatric care, this is another area for re-emphasis.  Every practicing psychiatrist needs to be aware of these mechanisms and at the minimum make recommendations for eye care, especially in aging patients.

The ophthalmology lecture was a good reminder that some disease mechanisms like oxidation can cut across several clinical specialties.  This provides a good opportunity for clinical psychiatrists to follow patients closely and potentially make more of a difference in their lives.
