UW 3rd Annual Update - Treatment Resistant Depression


























There were two presentations relevant to depression that were given at the UW conference this year.  The first was from Karen Dineen Wagner, MD, PhD from the University of Texas Medical Branch in Galveston, Texas.  Her message was a mix of the old and the new.  The old is the state of pharmacology of depressed children seems to have changed very little over the past 20 years.  This seem largely due to the fact that there have been few successful antidepressant trials in children.  This has led to the state where there are only two FDA approved medications fluoxetine and escitalopram based on a total of 4 clinical trials.  She  showed an additional 14 clinical trials of typical antidepressants including 3 that were positive for citalopram and sertraline but an additional negative study for the FDA approved medication escitalopram.  The difficulty in many of these trials is a high placebo response rate in the trials (40% greater than in adult clinical trials).  She recommended an informed consent approach explaining to the parents any time an off label approach was being used and the rationale for using any medication based approach.  She also recommended starting with the FDA approved medications for pediatric depression.

Her suggested approach to depression in children and adolescents is to start out with an FDA approved SSRI plus cognitive behavior therapy (CBT).  This is the most evidence based approach with the evidence rapidly disappearing at subsequent levels where the usual augmentation and substitution steps that are typically used in adults were suggested.  The Treatment for Adolescents with Depression (TADS) study was presented with the recovery rates for fluoxetine, fluoxetine + CBT, and CBT alone at 12, 18, and 36 weeks were presented.  The fluoxetine + CBT arm had superior results at 12 and 18 weeks but at 36 weeks the recovery rates were similar at 86% versus 81%.  Those are good results for any antidepressant trial and the placebo response rate in this study was more similar to the adult placebo response rate.  The results of this study were presented as a rationale for using antidepressants in adolescents with severe depression and/or suicidal ideation since the response rate for fluoxetine + CBT were faster than fluoxetine or CBT alone at 12 and 18 weeks and essentially the same at 18 and 36 weeks.

The issue of strategies for addressing SSRI resistant depression were presented in the form of a previous trial where 334 adolescents with SSRI treatment failures were randomized to a different SSRI or venlafaxine or SSRI + CBT or venlafaxine + CBT.  The trial done by Brent, et al showed that there was no difference in response rates switching to another SSRI or venlafaxine but switching antidepressants and adding CBT produced superior results.  Sides effects were greater for the venlafaxine arm with a slight increase in diastolic blood pressure and heart rate and a four fold increase in skin rashes - a complication that I have rarely seen in adults.  The overall impression was that CBT was the most effective intervention for adolescent depression but I am sure that most psychiatrists in the crowd were left wondering: "If I can't find CBT therapists for my adult patients with depression - what are the odds I can find them for my adolescent patients?  To me that has always been the critical shortage in psychiatry - not the number of people who can prescribe medications.

Others trials of medical interventions (omega-3 fatty acids, ECT, TMS, bright light therapy), psychotherapies (Interpersonal Therapy(IPT), family based IPT), and exercise were sparse.  Computer-based CBT has always been an underutilized modality and it showed that there were similar response rates between treatment-as-usual and an interactive fantasy based CBT called SPARX (Smart, Positive, Active, Realistic, X-factor thoughts).  In the game the child chooses an avatar and the goal is to restore balance in a fantasy world dominated by GNATS (Gloomy Negative Automatic Thoughts).  The SPARX game is available free online to residents of New Zealand.  New Zealand and Australia have been pioneers in the area of online CBT.  To find resources just Google "SPARX virtual therapy for depression".

Paul Holtzheimer, MD provided the adult perspective in the topic Management of Treatment Resistant Depression in Adults.  He made the epidemiological point that treatment resistant depression (TRD) is present in 10-33% of patients with major depressive disorder and in the U.S. that is about 1-3% of the population.  He had a fairly comprehensive agenda covering pharmacotherapy and augmentation strategies, electroconvulsive therapy, more recent non-invasive electromagnetic therapies and deep brain stimulation.  There was nothing new on the medication front.  After reviewing the basic medication groups, he suggested that the newest antidepressants offered no advantage over earlier medication.  He suggested that monoamine oxidase inhibitors (MAOIs) were being underutilized as a treatment for depression unresponsive to standard agents.  In the moderated discussion Ned Kalin, MD - the head of the department of psychiatry at the University of Wisconsin agreed.  The speaker said that he typically used phenelzine and tranylcypromine.  I personally have not prescribed either of these agents in some time.  I recall using them in situations where the person has treatment resistant depression and did not have any responders.  In those situations, response rates tend to be low anyway.  The other problem is that you have to think that your chronically depressed patient is going to be motivated and cognitively intact enough to adhere to the necessary diet, report what could be significant side effects and not try to kill themselves with the medication.  During the discussion there was a report of one patient who decided to eat high tyramine content food (prohibited on this diet due to a the risk of a hypertensive reaction) - have a stroke and die.  The patient in this case did have a stroke but did not die.  I personally know of situations where strokes have occurred, so this strategy is not without risk.

The augmentation strategies discussed were right out of STAR*D with the exception of using atypical antipsychotics with antidepressants.  Dr. Holtzheimer said that this was probably the most common augmentation strategy and the risks were discussed.  He and Dr. Kalin were advocates of augmentation with lithium and triiodothyronine (T3).  There were three slides on STAR*D showing cumulative remission and remission rates across all levels of care.  Those rates were 33% with initial monotherapy and 66% after 4 treatments and as expected less remission rates at each level of treatment change.  Dr. Holtzheimer made the point that the current rates of remission with medication and psychotherapy have really not changed since the 1950s and that makes electroconvulsive therapy (ECT) the most effective antidepressant treatment with a 50-75% remission rates and a >50% relapse rate in the first 6 months.  He touched on novel pharmacological agents categorized by neurotransmitter, neuroendocrine, or immunological systems.  He did not say much about ketamine (there is an intranasal preparation in clinical trials right now) but did mention that there is a IL-6 (cytokine) antibody trial going on right now.

He moved on to talk about more invasive therapies.  He presented a graphic that was a drawing by Papez.  To anyone trained in neuroanatomy around the time I was in medical school, many anatomy professors would present a saggital section of the brain and refer to the limbic structures as the Papez circuit.  At first I thought the drawing had a surprising amount of detail for a 1937 publication but then I went to the original article online (AMA web site) and found that the original drawing was not used.  The 1937 drawing had the surface anatomy correct but no tracts.  Papez mentions the amygdala three times in the last few paragraphs of his article but does not label it in the drawing.  Dr. Holtzheimer used this slide as a prelude to an article by Mayberg (3) providing a rational for deep brain stimulation as treatment for depression.  I plan to come up with a separate post in this technology based on several sources but right now there are a number of centers looking a deep brain stimulation for depression and addiction.  Dr. Holtzheimer briefly commented on transmagnetic stimulation (TMS).  There are apparently 4 FDA approved devices, use is expanding and insurance reimbursement is expanding.  He said it was 50% effective for treatment resistant depression.  I am highly skeptical of that number based on the people I see, but I also realize that I am seeing a highly treatment resistant with multiple comorbidities.  Seizure risk was listed as the most significant side effect.

Vagus nerve stimulation (VNS) has been around for about a decade.  I have seen a few of these patients and never referred anyone for placement of this device.  There is limited third part reimbursement and in my opinion waning enthusiasm for this technology.  The last time I interviewed a person with VNS, their speech quality changed every time the stimulator was active.  That is a significant side effect and I don't know if that has been addressed with current technology.   Transcranial direct current stimulation (tDCS), transcutaneous vagus nerve stimulation, and cranial electrical stimulation were all listed as having limited data.

Deep brain stimulation (DBS) was clearly the main focus of Dr. Holtzheimer's presentation.  The first article suggesting that it may be effective for obsessive compulsive disorder (OCD) was in the Lancet in 1999.  Based on that research DBS of the anterior internal capsule is an FDA approved indication for DBS.  An open label study suggested that it may also be effective for TRD and there were no adverse effects or neuropsychological effects.  Three additional pilot studies of DBS to the nucleus accumbens suggested that it may be useful for TRD and features of TRD like anxiety and anhedonia.  Since then there have been two randomized controlled trials of DBS to the ventral striatum subcallosal cingulate gyrus (SCC).  The first study (ventral striatum) was negative and the second (SCC) was stopped after a futility analysis.

The overall conclusion had to be that TRD was still a common and disabling condition.  The mainstays of treatment at this point are still the medications and ECT that we have had throughout my career.  My experience is that I can help most people get well, but there are significant obstacles even to standard care.  Every lecturer here emphasized the utility of cognitive behavioral therapy.  Like most psychiatrists, I can do cognitive behavioral therapy but by myself I can't meet the demand.  The people responsible for mental health policy and insurance standards certainly do not want to fund the recommended research courses of CBT for chronic depression.  There is no distinction for TRD versus non-TRD depression and no differential resource allocation.  That leaves most patients with TRD and non-TRD depression looking for "prescribers" who can see them for 10-30 minute appointments to get advice on how to recover and try various prescriptions.  None of the available care matches what top researchers recommend in these CME seminars, in articles, or in books.

We could do a lot better trying to live up to that standard while additional diagnostic and treatment strategies are developed.

Should Science, Engineering and Math Majors Go In To Psychiatry?






















I got an e-mail from a young electrical engineer the other day who was interested in psychiatry and asked me about some ideas he had to increase his exposure to the process of talking with patients.  He was interested in some experience with this before considering a change to medical school and psychiatry.  As I thought about it today, it brought back some memories about how science and math majors have been discriminated against at times in the medical school admissions process.  Back in the day when I was initially considering an application to medical schools, there was a General Knowledge section on the MCAT - (Medical College Admissions Test).  It was there purportedly to select people who were "well-rounded" and not just science majors with their shoulder to the wheel studying math and science.  Well rounded seemed to mean liberal arts majors and people with a broad exposure to art galleries, museums, theatre and culture in general.

There were a couple of things wrong with that theory.  First of all, it biased the test toward anyone who lived in a major city.  If you were a hayseed like me, you made a school trip to the Guthrie Theatre in Minneapolis exactly once in your high school career.   For everything else - you better be paying close attention to what happened in your English literature class.  Not a very dynamic approach to learning.  Contrast that experience with a friend of mine who is a New York born and raised Internist.  He had very broad experience with all forms of art including opera and ballet before high school and is one of the most brilliant people I have ever met when it comes to discussing and critiquing art of all forms.  All of that most likely originating in a childhood and adolescence steeped in the artistic milieu of New York City.  I know he didn't learn it in medical school.  Who do you think would do better on the old General Knowledge test?

The second problem is the general assumption that people involved in the humanities are more likely to be interested in people and take a humanistic approach to medicine.  There seems to be a bit of a loose connection there between temperament, personality and your intellectual pursuits.  People in the hard sciences must be rigid, lack warmth, be oblivious to the human condition, and lack empathy - right?  I have never found any solid evidence to support this.  I will concede that Communications majors do an outstanding job at weddings.  I recall going to a wedding where I knew the groom since he was an infant.  When he grabbed the microphone and launched into 30 minute impromptu act, I asked him where that came from.  His answer: "Communications major."  Apart from that, I have asked many good psychiatrists what their major was as an undergrad and a surprising number were Chemistry majors.  Those chemistry majors had no defects at all as physicians or psychiatrists.   They did as well as anyone else and I was glad that they were in the field.

As far as I can tell, the previous bias against science majors getting into medical school did not have a rational basis.  I can't be certain about whether or not it exists today but I can be sure that administrators keep manipulating the entrance exam.  In this commentary from a couple of years ago I point out that the stated goals of aspiring to think like a scientist is probably very congruent with being a senior level science major.  But I don't think that will translate to an admissions bias in favor of science majors.

Are there reasons to encourage engineering, math and science majors to go into medicine and psychiatry?  I think that there most definitely are.  At the highest levels, the technical aspects of brain science are exploding and future physicians and psychiatrists with a grounding in scientific thought and information science will be able to make the best use of it clinically and at the research level.  All of medicine is currently in the throes of very crude clinical trials that are often limited by a lack of specificity.  Most medications prescribed have limited efficacy and significant side effects.  That means just from the medical side, physicians in the forseeable future will be managing these medications and their side effects.   I think that a few dimensional comparisons across medicine and science and engineering may be useful:

1.  Economics - physicians are currently overworked and much of that work has little to do with patient care.  Practically all of the people managing physicians are right out of a Dilbert cartoon.  Most of medicine has been reduced to a rapid prescribing paradigm and businesses are recruiting non-physicians to do it.  That has already led to a reduction in the quality of care in psychiatry largely by eliminating psychotherapy, time spent with individual patients, and systems considerations of care.   Engineering in particular may be a more financially sound career with the opportunity to escape the fate of Dilbert.  Economics are not the only consideration.  I recently encountered a young petroleum engineer involved in oil exploration who was very successful and decided to go into medicine.  When I asked her about her motivation she said she wanted to work with and help people - even if it meant a significant hit to her salary and autonomy.

2.  Intellectual Satisfaction - scientific endeavors especially at the business level produce clear measurable results and the process frequently incorporates the theory that you learned along the way if you are an engineer.  Medicine and psychiatry are much more diffuse.  There are administrators and politicians ordering you around under the mantle of science who clearly know nothing about it.  You may find colleagues that are really not interested in the cerebral aspects of the field only the practical.  In medicine and psychiatry that can be stultifying when you realize that this involves a series of political arguments about conflict of interest and drug trials.

3.  Conflict of Interest -  Medicine and psychiatry have been under attack for some time by people who believe that there should be no contact with private industry, at least at the level of reimbursement for work being done.  All payments from private industry need to be reported in a national database and needless to say that discourages physicians from working with with the pharmaceutical or medical device industry.  This is a significant difference with engineering. As an  example, I contacted the IEEE and asked them about their policy on standards and was told that they encourage the participation of industry in the discussion of standards because of the expertise distributed within the industry and the need for those active discussions.  Medicine and psychiatry, largely due to the questionable theory that the industry will affect treatment decisions has embarked on a period of isolation from medical industries that may be alien to technical fields - especially to engineers.

4.  Politics - We are in a 30 year period of unprecedented discrimination against physicians by state and federal governments.  Like most American politics the implicit goal seems to have been to bring all physicians under the management of companies that are proxies for governments and on the face of it that strategy has been highly successful.  Practically all physicians are employees of large health care companies and supervised by people who know practically nothing about the work they do, but who are quite content to tell them how to do it.  Many of these policies, like recertification have a significant impact on physicians and their families.  They are not conducive to the idyllic balanced lifestyle.

5.  Subjectivity/Uncertainty - There is a high degree of subjectivity in medicine and in many circles that is considered a dirty word.  Most non-physicians fail to see the importance of subjectivity and how it relates to information transfer in biological systems.  The least creative try to pretend that it doesn't exist and they try to reduce everything to a 10 point scale.  They mistake these "scales" for objectivity and some sort of measurement.  They don't really understand what scientific measurement is.   They base entire systems of care on these failed measurement systems.  They can't be reasoned with and there has been a large proliferation of measurements that are quasi-scientific at best but that are used to assess physicians and processes.  Frequently meaningless data is collected and used to make decisions about care and how systems of care operate.  Physicians in these settings with a knowledge of science and measurement can be very frustrated.

6.  People - I have posts about the interpersonal dimension of treating people as a psychiatrist.  It is more rigorous than the interpersonal landscape of other physicians.  Psychiatrists treat a broad spectrum of problems and in some cases there are significant conflicts with the people you are trying to help that are based on an underlying mental illness.  Some of these conflicts affect some physicians more than others.  You may already be able to tolerate interpersonal conflicts better than your peers and that may make psychiatry easier for you.  Psychiatrists are also unique in that they are the only medical speciality that has groups of people who dislike them and routinely disparage them whenever they have the chance.  Being able to tolerate that will also make it easier for you to go into psychiatry.

These are some of the issues to consider if you are thinking about switching careers and going into medicine or psychiatry.   Medicine and psychiatry are not sciences - but we need scientists, engineers, and mathematicians.  They make good doctors and I am hoping that they can help medicine move out of the morass of political regulation and business theories and back toward the light.  At the same time, it is only fair to consider that in engineering it may be more possible to find a better work environment, a better lifestyle, more intellectual stimulation and better reimbursement.

That's about all I can think of tonight.  If you are a science or engineering student with additional questions - please feel free to post here and I will try to answer them about any specifics.  Please see the disclaimer below.

University of Wisconsin 3rd Annual Update







































I just finished the 3rd Annual Update and Advances in Psychiatry at the University of Wisconsin in Madison Wisconsin.  It is familiar turf to me because that is where I finished psychiatric residency training.  I was impressed with the first two updates and have covered my experience at the 1st Annual and 2nd Annual Updates on this blog in the past.  During the introductory comments, the Department Chair Ned Kalin, MD paid tribute to John Greist, MD and James "Jeff" Jefferson, MD who ran the conference for 37 years before it was taken over by the Department of Psychiatry.

The absolute high point of day one was a discussion of schizophrenia by Daniel Weinberger, MD.  I had seen him speak before.  In talking with Dr. Kalin about the conference Dr. Weinberger gave a more research oriented talk the day before in the department that was focused on more science and neuroscience that I wish I had seen, but the lecture he gave to clinicians at this conference was outstanding.  From the introduction Dr. Weinberger had apparently left the NIMH and is now working as Director and CEO and  for the Lieber Institute for Brain Development.   They have quite a unique website and faculty.  The title of his discussion was Neurobiology of psychosis in the era of genetic medicine and he offered some unique perspectives that I doubt are available in many places.  It was useful to see a focus on schizophrenia in a conference of this nature and a focus on how at least some of the cutting edge research is looking at therapeutic modalities that are unique rather than the usual isomeric approach to drug discovery.  It was also refreshing to hear that there is optimism out there rather than the usual doom and gloom about the the "pipeline" from Big Pharma is running dry and there will be limited options for the future.

The Weinberger lecture had an interesting introduction that focused on brain imaging studies in psychiatric disorders.  It was well done, well argued, and based on his American J Psychiatry article that was published earlier this year (2).  He points out that while brain imaging has been the "centerpiece" of neuropsychiatric research that it is still fraught with technical difficulties.  In many of the articles that seem to make the lay press there is almost nothing that is not associated with brain changes.  He showed examples attempting to correlate viewing pornography with the frontostriatal network, increased gray matter volume secondary to lithium use, and other common artifacts and he concludes that most illness associated imaging findings are likely epiphenomenal.  To anyone trained as a chemist in their undergrad major who has experience with nuclear magnetic resonance (NMR) scanning of organic molecules a lot of this comes as no surprise.  To anyone used to reading decades of similar research (like quantitative EEG) and realizing that the pilot studies never panned out even after some were published in very prestigious journals this should also not come as a surprise.  Weinberger offered the technical explanations for why these issues occur and also some studies that seemed to be sound.

The bulk of his lecture was dedicated to the genetics of schizophrenia.  The opening slide not only contained a lot of information it was a tutorial in how to present information in PowerPoint format.  It was titled "The emerging genetics of schizophrenia".  In the upper left corner was a graphic from Gottesman's work with 11 bar graphs above the same axis showing risk for schizophrenia based on relationship to the index case.   Right below that was a table of Exome Sequencing: Rare Variants showing rare structural variants in schizophrenia with the title of a report to the right.  In the upper right hand corner was a Manhattan plot of 108 GWAS loci on all human chromosomes and the reference to the report in Nature.  It was a beautiful slide in terms of presentation and information content.

He went on to discuss genome-wide association studies (GWAS) and what they imply for the genetics of schizophrenia.  Inheritance of schizophrenia is widely considered to be polygenic and has been for some time.  He framed this issue as there being no psychiatric disorder gene and I thought that was a useful reframing because it speaks to studies that are looking at a very few point mutations associated with schizophrenia, and it is easy to think that this gene is the cause of schizophrenia rather than conferring risk for the disorder.  He demonstrated this with a risk profile score (RPR) for developing schizophrenia based on an additive count of all risk alleles.  In the example given the risk profile for the highest risk score had an odds ration of 15-20 to 1 for developing schizophrenia.  He went on to review the evidence for schizophrenia as a neurodevelopmental disorder.  That included some epidemiological data such as artificially imposed famine in China and the Netherlands and the subsequent increase in the incidence of schizophrenia in the respective birth cohorts (1).  He showed that de novo mutation in schizophrenia overlap with more traditional neurodevelopmental disorders like autism spectrum disorder and intellectual disability.  He showed that genes from all three disorders are overexpressed during the fetal period and this is a pattern seen in neurodevelopmental disorders.  

This was compelling stuff.  I come to this conference very year to get rejuvenated and it worked again this year.  The only regret I had was that time has just about run out for me.  I am no longer a young science major with an interest in human behavior and how the brain works.  I don't have time to go back and do a fellowship with Dr. Weinberger or a sleep fellowship or any number of other interesting things that I see at conferences.  I can understand the concepts,  teach them, and advise younger colleagues and residents on what is available and why this is a compelling field whenever I can.  I can also continue to get the word out that psychiatry is alive and well, that the best critics of psychiatry are trained as psychiatrists, and what passes for psychiatric criticism on blogs and in the press lacks a critical element called scholarship.  And as important - you don't have to be Kandel or Weinberger to be scholarly and apply what you know about the science to what you do every day as a psychiatrist.  Equally important - knowing the theory and what can and cannot be applied yet - is an important aspect of being a physician.

It was a good weekend.

Tic - toc......





















Or why advising physicians on how to manage their time is not generally a good idea.

I will cut to the chase on this one.  The answer is two fold.  Medical practice is by its very nature inefficient.  Secondly, there are just too many people incentivized to waste physicians' time.   After reading another blog on this topic,  it is apparent that most people attempting to give advice to physicians either think that we are quite slow on the uptake or they have no appreciation of what medical practice is like.  The most misunderstood part is how much time physicians are forced to waste on work that is unnecessary to the work of patient care.

I preface my remarks by saying that in the many visits I have had to physicians of all specialties, I have never been seen on time and consider myself lucky to be seen within 30 minutes.  My all-time record was waiting about 30 minutes to be seen in the emergency department one day and then having to wait another 8 hours to be discharged by the physician who saw me for a rather uncomplicated problem.  So there is no expedited line for physicians in clinics, EDs, or hospitals.  We wait like everybody else.

The premise of efficiency in medical practice is a favorite of administrators and other salespeople pushing valuable time saving devices for physicians.  Primary among them has been the electronic health record or EHR.  I think there is finally a consensus on the fact that it has basically created a large pool of physician-stenographers that spend additional hours each day typing in documents that are designed for billing and coding purposes rather than enhancing the care of patients.  I will roll out my frequently stated comparison.  In 1981, two interns and myself could complete all of the daily documentation on a busy 30 bed neurosurgery service during the 2-3 hours that we were rounding with the senior residents and doing all of the other associated work that day.  Today it would probably take an additional 4-6 hours to do that work and it would mean less time in the operating room learning neurosurgery and attendings wondering about what happened to the team.  I have heard of some surgical services who hire retired surgeons to come in as scribes to do operative notes to reduce the paperwork burden.  The documentation burden is worse in primary care.  All of the advice on how to shift your time around to allow ample time for the documentation never considers the fact that time slots in clinic are rarely set in stone.  People show up 30 - 60 minutes late and expect to be seen.  Emergencies happen, and need to be dealt with while people are stacked up in the waiting area.  Labs need to be reviewed and all of the outgoing tasks (paperwork, phone calls, prescriptions, consults) need to be handled.  None of these are trivial tasks in terms of the time it takes to get them done.  Some of my friends in Endocrinology walk in on a typical morning and have over 250 test results stacked up in a computer queue that they need to review on top of the full patient schedule that day and do something about them - in some cases right away!

Outpatient clinics have certain routines every day depending on the specialties involved and the amount of staff available.  As an example, primary care clinics generally have many more staff to room patients, take vital signs, handle calls, and schedule patients than outpatient psychiatry clinics.  But even clinics that are more fully staffed can easily be overwhelmed by the demands placed on them.  There is no end to nonsensical ideas about how physicians can be more efficient, but there are always several facts that all of the advice givers typically ignore:

1.  There are mathematical laws called power laws that govern how many patients can be seen by physicians.  It is a mathematical fact.  All of the speculation about computers doing thousands of physician tasks per second are really meaningless at this point.  All of the administrators talking about "productivity" are as meaningless.  Productivity happens when real quality treatment occurs that changes a person's life.

2.  Despite all of the business focus on productivity, the business administrators in health care have done nothing but create obstacles to physician work.  Wasting hours every day doing tasks for insurance companies and the government is basically a case in point.  I would estimate at least 40-50% of all physicians time is wasted on these tasks.

3.  Every physician in this country who works in a clinic setting is an independent practitioner.  They don't need supervision, they just need to keep their license current and abide by the medical practice acts in each state.  The only time they are supervised is when they work in a clinic or hospital setting and suddenly they vertically integrated into departments and placed under a supervisory hierarchy.  That hierarchy is by definition very inefficient.  A lot of time is wasted implementing the next great ideas of the supervisors and in some cases sitting in long drawn out meetings about the financial status of the department.  Apart from the administrators needing to demonstrate that they were actually doing something (that is frequently debatable) - these meetings were generally a waste of time.  I don't discuss all of my cases with business administrators - why would I want to read their spreadsheets?  How can putting 20 or 30 physicians in the same room for a meeting be anything but disruptive to clinic and hospital schedules?  The business and government initiatives to force physicians into these employment situations leads even less time to see patients.

4.  Physicians have been hit hard by the EHR and more.  Like many other jobs there is an implied 24/7 electronic access.  When physicians are not completing documentation after hours or at home,  they are answering e-mails and texts about patient problems.  It is not uncommon to start clinic and notice that is addition to a full schedule of appointments and labs to review that there are also 20 or 30 e-mails and messages through the EHR - many marked urgent.  If you are the first appointment in clinic that day and your physician said that she had to respond to an urgent problem - believe her.

I can understand that this post might elicit widely varying emotions.  Overworked and burned out physicians will see the obvious truths here and will wearily think: "Been there - done that."  There will be readers - like one who suggested that I drive a Porsche rather than a soccer mom van - who will be outraged that a rich doctor dares to complain about working conditions.  There will be readers who think that physicians should not complain on basic principles.  I guess they don't want physicians acting like other workers when this is supposed to be a privileged and noble calling.  They don't recognize that physicians are managed like production workers and not professionals.  There will be those trying to silence complaining physicians by suggesting it is "unprofessional" or characterizing legitimate complaints as "whining".  They generally have their own political agenda  that includes managing physicians like production workers.   It should be apparent that there is no extra time to manage.  There are many people who will say they are working as hard as doctors and therefore doctors don't have a legitimate point.  I would say that I don't doubt it at all that too many Americans are working long and hard hours.  The question is whether there is also a public safety consideration.  Most workers where there is an element of public safety have limitations on their hours.   Practically all physicians are running a huge time deficit that can't be overcome by gaining 5 or 10 minutes from the occasional appointment that goes well.

Irrespective of the emotional reaction to this post there is a very basic thought experiment that anyone can do.  It will highlight a suggested orientation to the problem.  The question is - when you see a physician do you want to see somebody who is burned out, fatigued from people wasting their time and trying to get them to do more busy work?  Or do you want to see a physician who is energetic, enthusiastic and has enough time to dedicate to you or your family member?

I personally will take the physician who is energetic, enthusiastic and has enough time to focus their energy on their family and learning more about their field.  That is not happening in many places today.      

And for all of those people who want to give physicians more advice on how to be more efficient in cramming 12-16 hours of work (much of it unnecessary) into 8 - here is a bit of advice for you.  Step back and let us do our work - we were doing quite well without you.

Is Susceptibility To Terrorism A Developmental Risk?





I think it was about 1967 when I was playing football with my usual group of friends.  We played football every night for about 8 years.  One of them put on his Army jacket after the game and I noticed that he had a small solid blue button affixed to the lapel.  I asked him what it meant and he said "Students For A Democratic Society."  That was the very first time I had heard of the SDS.  In those pre-Internet days, the only access to radical literature was filtered through popular press in articles that were intended to sell copies.  There were some counter culture approaches like the Whole Earth Catalogue that advised on how to access non-mainstream forms of writing.  It was also possible to travel to one of the universities at the time that were the sources of radical thought and listen directly to what some of the student leaders had to say.

As I pondered that blue button, my next contact with radical thought occurred in the freshmen philosophy course of my liberal arts college.  I ended up in that class like several of my football playing colleagues.  The only reason I went to college was to play football and eventually become a football coach and physical education instructor.  My only disappointment so far was that the college did not have a PE major.  One of the texts for the philosophy course was Eldridge Cleaver's Soul on Ice.  The only thing making my life more complicated at the time was that the instructor graded on class participation.  If you didn't speak up, he would scan the list of names and call one out.  It happened that day in the fall of 1969 that he called my name and asked me what I thought of some aspect of Cleaver's radical text.  I was seated in the back row as 44 sets of eyes turned to stare at me.  My voiced cracked a little bit as I delivered a several minute interpretation.  I wish I could recall what I said that day because it was one of many turning points for me in college - but I can't.  All I can recall is the Professor's response:  "That is good Mr. Dawson.  That is very good."  From that point on, he knew I read the stuff and and could be counted upon for reasonable commentary.  When I sat down the introverted football player seated next to me - gave me a thumbs up.

The 1960s and 1970s were turbulent times.  The same guys I played football with - every day for years - were enlisting in the Marines and going to combat in Vietnam.  One of our group died over there and his name is on the Vietnam Memorial.  It was a very unpopular war and in those days protesting unnecessary wars was popular and became more popular as time went by.  My overall recollection was that information about the war was much more tightly controlled in those days than it is now.  That may have been part of the backdrop for protests, but there was more.  My home state of Wisconsin was a hotbed of radical political thought centered at the University of Wisconsin in Madison.  There were protests in the street and riot tactics used against the protestors.  At one point the windows were broken out of the stores so often on State Street that there were replaced with wood.  One of the retail pharmacies there eventually replaced their windows with bricks and mortar so that the store resembled a bunker with small windows up at the top.  It was an exciting place to visit due to the activity on campus and high level of emotion.  There are detailed descriptions of the history of what happened in Madison available around the Internet and I am not going to excerpt them here.  One of the references suggests that the three radicalized university campuses of that era were Madison, Berkeley, and Columbia.

The protesting in a Madison seemed to peak on August 24, 1970 when 4 men blew up the East Wing of Sterling Hall.  That explosion killed a 33 year old physics researcher, injured 3 others, and destroyed years of research - in one case 25 years of research.  The apparent target was Mathematics Research Center because it was funded by the US. Army and the motive was to protest the war in Vietnam.  The 4 men involved ranged in ages from 19 to 23.   The same group was involved in an earlier attempt to bomb the Badger Army Ammunition plant in Baraboo, Wisconsin just down the road from Madison.  Depending on who you read, this bombing changed the course of war protests in Madison.  Many people left the anti-war movement when they realized it contained an element that were not concerned about the lives of others.  Even though many seem to agree that the incident seems to be forgotten, I think there are questions about whether the almost total lack of protests and radicalization today is not in part due to this lingering concern.  In his book Days of Rage, Bryan Burrough described the Sterling Hall bombing as having a transformative effect in that it refocused conversation from the Nixon administration to the bombers and assigned a larger responsibility to anyone who encouraged violence either directly or indirectly.

Burrough goes back and does a good job of making sense of what happened in the 1960s and 1970s.  He covers all of the main radical groups and points out that terrorism (of a domestic kind) was much more widespread then than terrorism of all forms is now even though it was less lethal.  To cite a few examples, in 1972 there were 1900 domestic bombings in the United States.  Bombings were occurring daily and an FBI agent in the book referred to it as "commonplace".  One of the commonest sources of explosives for bombs was dynamite stolen from construction companies.  A Senate investigation in 1970 showed that the amount of dynamite being stolen from quarries and construction sites went from a total of 12,381 pounds in 1969 to 18,989 pounds in the first 5 months of 1970 (Burrough, p151).  By the end of that year most states had passed or were considering new laws limiting the sale of dynamite.  Radical groups also targeted police officers in their activity with several municipalities reporting several fold increases in assaults and homicides of police officers.      

Although Burrough's book is not written from the perspective of developmental psychiatry, there are important themes there that highlight what I think is the most plausible answers to both the recruitment of terrorists and some mass shootings that involve men in this age group with no clear mental illness.  First and most primary is emotional maturity.  Emotions  are both necessary for optimal decision making and at the same time can obscure clear decisions.  The factors that result in that optimal decision making are under delineation but brain maturity, the absence of intoxicants, and appropriate social context and boundaries are all important  aspects of the process.  It is clear from reading Days of Rage that the terrorists of the 1970s like many of their peers - lacked a lot of this.  Burroughs documents disagreements based on boundary issues within some of these groups and in some cases naive approaches to building solidarity within the group that was nothing more than sexual acting out.  Envy was a notable dynamic.  Many of the Weathermen were described as being envious of the Black Panthers.  Some of the radicals most notably the Weathermen were so naive in their quest to recruit and save the working class, that they did not realize that the working class did not want to be saved - at least by them.  The violent activity seemed to be driven at times by narcissism more than anything else.  Being the most violent person in a group of otherwise ambivalent terrorists conferred a certain status that seemed to last a long time.  Late adolescence and early adulthood is also the last great moment to be bonded to a group of your peers.  The next life stage for most people involves family units taking priority rather than peers.  Bonding around a life changing event like a revolution or even much less visible military service can be a powerful experience if it really happens.

History tells us that the revolution did not happen.  Several of the radicals from that time are interviewed and talk about being convinced at the time that it would.  The author refers to this thought as delusional at times, but it is more likely quasi-delusional - shared with such emotional intensity that a very low probability event seemed likely.  Some ponder their sparse legacy or rationalize a lot about what happened.  One interesting twist is that many of the radicals who were never convicted and even some who were completed their college degrees and even went on to professional school.  Some became lawyers and teachers.  One became a prominent psychiatrist.  That aspect of their transition from advocates for a violent overthrow of the system to being an integral part of it separates domestic terrorists from those who are involved in countries without that opportunity.  That may be what separates countries who may transiently have several hundred terrorists who fade away in a fraction of a generation to generations of terrorists living in an abandoned country like a revolution has happened.

There are experts in this area who have different ideas about classifying terrorists - but they are generally based on stable adult personality structures.  I  think that there is a lot to be said for a model that looks at susceptibility to recruitment into terrorist organization as a developmental predisposition and one of many decisions that needs to be made in the transition to adulthood.  That transition is fraught with bad decisions that are the product of the highly variable judgment that can be readily observed in adolescents and young adults.  That includes a prominent bias starting in adolescence that you are making the same decisions that adults would make or that you would make if you were slightly older.

What happened to the domestic American terrorists in the 1970s and how quickly they were forgotten is probably a case study in the problems with this process.  It is very likely that process continues to this day when young adults are recruited to work as foot soldiers in organizations that have similar violence-based ideologies that appeal to very few people.

Watson Replacing Radiologists?




I like reading the Health Care Blog.  It typifies what is wrong with the management of the American Health Care system and I suppose blogs in general.  It is a steady stream of bad ideas and political rhetoric.  The best recent example was a little piece about radiologists called Will Watson Replace A Radiologist - Ask A Radiologist.  Radiologists either don't read this blog or they can't be bothered since the only comment at this point is from a rheumatologist on the necessary consultation and collegiality with radiologists.  The author of the main article is taking the perspective of being both threatening (Can the IBM Watson machine acquire the image reading capabilities of a human radiologist by "reading" a large set of clinical images and reading them at a much faster rate than a radiologist?) and advising (The only way that radiology will survive is to demonstrate their value to patients and colleagues by connecting with them?).  The author's conclusion is very explicit: Connect or be replaced.

Over the past thirty years my experience with radiologists has been positive and in some cases outstanding.  That dates back to the early days of being the medical student or intern responsible for carrying a stack of heavy and awkward films around.  I remember not having a film on a Cardiology rotation and regretting it: "Mr. Dawson - what made you think it was not a good idea to have the chest x-ray of this patient with mitral valve disease?"  From that point on radiologists were my friends.  That was an era before there was a lot of managed care penetration and I always rotated at public  hospitals and VA hospitals anyway.  You could always find a radiologist back in the dark confines of a reading room.  The interns and residents had certain staff members that were the go-to staff in terms of teaching and also amazing observations.  They always pointed out what we were missing.  They collected teaching files and teaching cases for us to learn from.  Reading rooms could be bizarre places in those days.  Very large films clamped on reading boxes.  In some cases entire rows of films - 10 to 12 wide, could be rotated on a belt device.  The radiologist would need to recall when they saw the film and press down on a foot pedal until the correct film popped up.  On many days row after row of films would need to be surveyed to find the one you wanted.  In the early days of spinal CT, many films had to be viewed on each patient.

I did not forget my positive experiences as a resident when I became an attending physician.  All the images I ordered on my patients had to be seen.  I would still go down and pull the films and where necessary review them with the radiologist.  Now I had neuroradiologists to work with and they were excellent.  The medium was changing.  Eventually all of the films went away and when I went down to radiology, the reading room was still there, but now it was a computer terminal with two monitors.  The images could be immediately manipulated to show the best view.  It was no longer necessary to pull the film off the cassette and illuminate it with a bright light.  I could always ask them questions, but as time went by they were under a greater time crunch.  Now all of the dictated reports were available on the phone system and you were encouraged to listen to all of the reports.  Asking to review a series of films without listening to that report was frowned upon.  At one point in time we were all members of the same clinic, but soon all of the radiologists were spun off into a different company.  They were the same people,  just no longer affiliated with our clinic.  By  that time managed care was trying to get everyone on a productivity scale and radiology seemed like an ideal speciality to crank up the productivity expectations.

In addition to the direct experience with radiologists, the author here also seems to not recognize the value of a human brain as a processor.  I teach neurobiology to students, residents, and physicians.  Part of the job of any lecturer is to help people stay awake.  Just before I delve into the frontal cortex and its connections to the ventral striatum, I put up a slide with a fact from one of my IEEE journals:

"Equivalent computing power (depends on the simulation) using today's hardware may require up to 1.5 gigawatts to power and that is equivalent to 0.1% of the US power grid or the output of a small nuclear power plant..."   IEEE Spectrum 2012

I ask the students to speculate on how the human brain has such a tremendous amount of processing power and how it is different from computers.  Even though the audience is generally tech savvy young physicians or students, I have never heard the correct answer.  One of the correct answers is the fact that the human brain is an unparalleled pattern matching device.  There are papers where it has been estimated we can each recognize about 80,000 unique patterns.  I start to go down the list and end with studies of radiologists, dermatologists and ophthalmologists demonstrating superior pattern matching and pattern completion skill.  But I also point out, it is why that you can't learn medicine from a textbook.  It is why you need clinical exposure before you can safely practice.   You need to acquire those skills.  To my knowledge, there have been no good papers written on available pattern matching in human diagnosticians compared with the cognitive tasks they face.  For example to be a good radiologist, how many unique patterns and variations do you need to be able to see - 10,000, 50,000?  The answer to that question is critical and yet we do not know the answer for radiology or any other medical specialty.  If the number if less than 80,000 (and we don't really know this confidence interval) - Watson may have the speed but not necessarily the accuracy.  Will Watson be analogous to the current ECG computer - a general normal/abnormal reading, a reading on measurable dimensions, and then not much on equivocal cases?  Only time will tell.

So I think this Health Care Blog post has the valuable lessons of most of their posts.  I don't know the author, but it is clear that he has not worked with radiologists as long as I have.  Not just the consultations backlit by reading boxes, but the telephone conversations about the best possible test to use to investigate the problem.  If he had worked with radiologists he would know that they have always been connected throughout the careers of most physicians.  The only obstacle to that connection has been corporate medicine.  The author's seemingly friendly advice is disingenuous.  If the business administrators who run health care really wanted radiologists connecting - they would get reasonable productivity compensation for that activity.  They would not need to connect and then run back to their terminal and read enough films to make up for the period of time they were in a conference or informally teaching residents from other specialities.  I think that the admonition to connect probably means to connect with the business administrators running the health plans.  Come back into the herd and let us tell you how many images to read, just like we tell other physicians how many patients they have to see.  Advising physicians on how to behave is also a well known strategy to manipulate them.

The real message is come back to the herd or be replaced, because there is nothing that would make an administrator's day more than replacing physicians with machines - especially physicians that they have no direct control over.

IBM knows that and I know that........

An equally important question is why Watson can't replace business administrators?  They seem to have the requisite lack of technical expertise and creativity.  They need a very basic level of pattern matching to do the job, certainly no training in it.  It would seem that a very basic program to optimize the working environment for physicians, health care workers and patients would be more ideal than dabbling in an area where real expertise and collegiality is required.  I can only conclude those concepts are alien to the ever expanding group of administrators whose reason for existence seems to be managing people - whether they need it or not.

Supplementary:  Although I could not work it into the above post another insidious effect of corporations on medicine has been taking teaching out of the loop.  Radiology teaching files and teaching rounds were always a rich source of learning for students and residents.  It is a required skill on most board exams.  I recall approaching an administrator about preparing teaching slides for the residency in-training exam.  It is quite easy to copy de-identified images onto PowerPoint slides for review and these images routinely appear in all major medical journals.  I will never forget the response:

"Dr. Dawson - why would we want our images to appear on teaching slides?"

Just another sign of the apocalypse.

Current Treatment of Respiratory Viruses - More Homilies






With Permission: SIB Swiss Institute of Bioinformatics,

Philippe Le Mercier, ViralZone.


My Facebook feed got me going today.  I get the Mayo Clinic feed since I consider their clinical care and some of their research to be the best in the world.  Of course social media is much less rigorous and sometimes it comes down to just advertising and promotion.  That was my assessment of the link to this document this morning.  It is a business document that purports to give advice on how to decrease your chances of a respiratory infection this winter.  Some of that advice is given by a Mayo Clinic Infectious Disease specialist and a Cleveland Clinic family physician.  There was one number I had not seen before and that is the Number Needed to Treat (NNT) for the flu vaccine is 40.  Forty people need to be vaccinated to prevent one case.  The advice is the usual set of homilies about respiratory infections including get the flu vaccination, wash your hands, sneeze into your sleeve, take care of yourself and stay home of you are sick.  In other words, there is no way in hell that you are not going to get sick at least once this winter.

Our continued 1950's approach to viral infections remains a mystery to me.  Certainly there are technical problems with trying to design vaccines for over 200 viruses that can cause the common cold.  But the reality is, vaccine design for influenza virus - easily the most lethal of these viruses is obviously not so hot.  As far as I know, vaccines for the most common of the cold viruses - Rhinovirus - is non-existent.  Anti-viral medications for respiratory viruses are more controversial.  Looking at the most popular one Tamiflu or oseltamivir.  The NNT to prevent one death may be 1,800 - 3,200.  The NNT to prevent one hospitalization may be 97 to 142 depending on criteria.  The NNT group suggests somewhat better NNTs of 36 and 83 for preventing a culture positive case of influenza and preventing pneumonia respectively.    Contrast that with the NNT for antidepressants of 5-10 as determined by Leucht, et al (2) in their comparison to other medications for various medical conditions.  And you thought antidepressants were ineffective?

Infectious disease respiratory virus research is a goldmine for all of the Luddites out there.  There are a number of web sites that provide free access to just about everything you ever wanted to know about every virus known to man.  The viral particle shown at the top of this page is the order that contains Rhinoviruses one of many common cold viruses and one of the viruses that may be responsible for the expression of asthma in predisposed individuals or exacerbations of asthma in asthmatics who are asymptomatic.   This illustration is from the ViralZone, one of many free online databases with detailed information about the molecular biology and genetics of viruses.  If I was an aspiring Luddite wanting to be provocative about the field of medicine being stuck in the 1950s despite the availability of all of this advanced information - this would be a logical place to start.

In previous posts here I have also critiqued the lack of attention given to environmental approaches to respiratory viruses and the fact that the airborne nature of some of these viruses is not acknowledged - possible because airborne viruses are not contained by hand washing and other direct contact techniques.  It s well know that viruses can be collected in the heating and air conditioning systems of public buildings and that altering the humidity and air flow characteristics in those buildings can change the viral concentrations in the air.  Whenever I have mentioned this to the administrators of buildings where repeated respiratory epidemics swept through the staff - I got the same response that I received from an airline after I reported a severe respiratory infection after one of their flights: "We are really sorry that you had flu-like symptoms after your flight and look forward to your future comments to help us improve our service."

What?!

 Time to get serious about respiratory infections and come up with some effective interventions.  Effective medication to prevent viral replication and spread in the infected and to create barriers to infection would be ideal and so would environmental methods to reduce the infection rate.  Considering the strong incentives in America to work while sick and considering that the average worker is going to get 2 to 3 respiratory infections per year that can last up to 3 weeks in duration means that very few of us and the patients that we treat are not going to be exposed and infected.  With the current advanced knowledge of the pathogens and modern heating and air conditioning systems it seems like a lot more could be done right now.

Does Publicizing Mass Shooters Benefit Anyone?





I ran across this perspective posted on the Kottke blog.  It is basically a journalist writing an opinion piece about why the names of mass shooters should be used in the media.  I think it is a reaction to the banning of the use of the names and details of mass shooters by some law enforcement and the media.  The Sheriff in the most recent mass shooting incident refused to release the name of the shooter.  The argument against releasing the name of the shooter goes something like this.  At least part of the motivation of some of these shooters involves the fame and publicity that they will achieve based on the incident.  The mass shooting incidents have been in my estimation fairly compared to terrorist incidents where the victims are killed in some of the most horrible and sadistic ways possible as part of the media campaign by these organizations.  It enhances any kidnaping and extortion threats that they may have and also enhances their image as a ruthless and single-minded entity.  Until recently that behavior was also a ticket to widespread international media exposure.  When the media cycle becomes knee jerk in response to mass shootings or terrorist events it is predictable no-cost publicity to both types of perpetrators.

There is additional evidence in the personal effects of many of these shooters and well as evidence from the staging of the events that publicity is a strong motivating factor.  The shooters often have computers and written statements about the motivation for their acts, and some of that material describes the event as something for the world to see.

The counterargument from the journalist seems to be that it is important for the public to hear all this information.  He makes the expected argument of the press that all of the news needs to be reported.  He also spins the political angle and suggests that conservative gun advocates including the sheriff involved in the most recent incident and then Fox News have elected not to name the perpetrator and connects this with the right wing tendency to talk about mental illness being the problem and not uncontrolled access to firearms.

I am at the point where I cringe when reading these highly politicized arguments probably because that is all that I hear when it comes to psychiatry.  The general form of the argument is that people taking a certain position have a certain ideology and therefore the conflict of interest issue reigns supreme.  Because a news service or a sheriff have been identified as being right wing and supporters of continued open access to firearms, anything they say about maintaining the anonymity of the perpetrator can be discounted based on conflict of interest.  In other words, by maintaining the anonymity of the shooter and focusing on the mental state of the shooter, the focus is shifted inappropriately away from more functional legislation to reduce firearm access.  The writer acknowledges that part of the motivation of some of these shooters is publicity or infamy whether they survive or not.  It is hard to deny because a review of the personal effects of some of these shooters makes it explicit.  The author takes the view that denying this publicity essentially gives the appearance that something is being done and this is bullshit.

First off, that does not meet my definition of bullshit from the definitive essay by Frankfurt.  According to Frankfurt, the main differentiating point between bullshitters and liars is that bullshitters have a blatant disregard for the truth.  The truth in this case is that irrespective of political motivations it is highly likely that denying these men the publicity that they seek will result in fewer of these crimes.  It might even provide a public health path to treatment for many of these individual instead of acting out.  I would suggest statutes that address the issue of how mass shooters should be handled in the event of any incident and would not only see anonymity as being important, but also confiscating property and all of the written material and images from the perpetrator and making them available for academic study, but not for the evening news.

The author also seems blind to the role of journalists in this process.  Every massacre triggers the standard response from journalists that I have written about on this blog many times.  All of the shocking details, the interviews with the aggrieved, the response from politicians, and the "profiling" of the perpetrator.  Then after a few days, the President comes on and we are all told to move on.  It seems that the President in his latest address has questioned the value of this process before members of the press have including this author.

My conclusion is that there has to be obvious progress in the area of gun control (yes - I said control).  But I have also accepted the fact that the power structure in this country does not have to yield to public opinion.  My decades of treating violent and aggressive people have also led me to understand that this is also a public health problem and as a public health problem - multiple measures need to be in place.   Restricting wide spread publicity for the perpetrators is one of many logical options.

There is also the issue of contagion.  Does a large incident with a lot of news coverage trigger copycat crimes?  There have been some anecdotal reports that copycat crimes occur in the specific area of school shooting.  The authors of a recent PLOS article (2), analyze the USA Today Mass Killing database and the the Brady Campaign School Shooting database.   The original databases and any modifications to them are available at this link.  The authors comment that a contagion model has been applied to several natural events like the financial markets, burglaries and terrorist attacks.  The authors specify the model they are using and go on to show that according to the USA Today database there was a mass killing (involving 4 or more people killed) every 12.5 in the US.  For the Brady database school sooting occurred every 31.6 days.  The authors illustrate there is a contagion effect for mass killings involving firearms but not mass killings that do not involve firearms.  They also show correlations between state prevalence of firearm ownership and mass shootings, but the authors note that mass shooters commit suicide 48% of the time and that is much higher than the expected suicide rate by perpetrators committing a single act of homicide (5-10%).  Mass shooters who commit suicide also kill 22% more people than mass shooters who do not.  The graphics and statistics in this article are great and I highly recommend a look at the graphs showing what part of the data is due to the contagion effect.  I also applaud the authors efforts to publish essentially public health research in an area that has been actively suppressed by Congress.  Scientific research on firearms policy is apparently incompatible with the Second Amendment.

So it turns out that there are probably legitimate reasons for withholding the identity of mass shooters and decreasing the disclosures about the incident and in some cases the audiovisual material that they have produced to promote their activity.  There is a well known journalistic tendency to wrap themselves in the flag when it comes to their not having complete access and the ability to disclose information, but the process is far from perfect and in many cases they defer to national security.   In the case of the databases involved there is clear asymmetry in terms of which incidents get publicity and which do not.  This is an opportunity for them to provide some news about public health interventions to prevent violence and mass shootings.

I don't think the importance of the notoriety or contagion factors in motivating mass shooters can be cancelled out by a conflict of interest argument.  But the conflict of interest card seems to be played like it is the trump card these days.

I also don't accept the "we as a society have made our choice" argument.  It's not really them it is us.  That argument is a stark contrast to how our government runs.  "We" are no more responsible for a society flush with guns that "we" were for three unnecessary wars based largely on fictional threats.  That oligarchy can function primarily with the full cooperation and lack of critical analysis by the American press.  The fact that late night comedians can produce more analysis of these issues than mainstream journalists is an indication of how much serious reporting is lacking.

There is probably no better example of reporting deficiency than how mass shooting incidents have been handled for decades.

The Problem With Benzodiazepines.....




I want to thank David Allen for the inspiration for this post when he commented that as an addiction psychiatrist, I was probably seeing a skewed sample of people addicted to benzodiazepines and that might be why I have such a jaundiced view of them.  I use the above bubble diagram to illustrate how benzodiazepines are prescribed by docs like me with a strong bias toward preventing addiction compared with physicians who have no such bias.  To make sure that we are on the same page, benzodiazepines are all technically tranquilizers or sedatives.  They marked a therapeutic advance from the earlier barbiturate class  in that their therapeutic index (ratio of the drug that produces toxicity in 50% of patients to the dose that produces a therapeutic response in 50% of patients) is much greater than earlier tranquilizers like barbiturates.  The practical measure is that it takes much higher doses to produce respiratory arrest and death.  Despite the increased safety these drugs are addictive.  People can develop a tolerance and in some people they produce a euphorigenic effect, very similar to the effect of alcohol.  Some people describe benzodiazepines as "alcohol in a pill."  Unfortunately we do not know the percentage of people where that occurs or how to detect them. There are many common clinical situations where the safety margin of benzodiazepines is cancelled out by other factors.  Mixing them with alcohol and opiates are two of the most common dangerous situations and if you are treating addiction - you see that happen all of the time.

Rather than list the entire table of benzodiazepines, I am going to list the commonest ones that I see being abused.  In order from the most frequently abuse that group would include alprazolam (Xanax), lorazepam (Ativan), clonazepam (Klonopin), and diazepam (Valium).  Of those compounds Xanax Bars or 2 mg alprazolam tablets seem to be the most commonly abused by far.  The maximum recommended dose of alprazolam is 4 mg/day and I frequently have seen people taking 8-20 mg/day in combination with other street drugs.  Benzodiazepines have all been generic for a long time so they are very inexpensive to purchase if you have a prescription.  If you don't have a prescription and acquire them illegally the "street value" of a drug is a sign of abusability.  The average street value of alprazolam is about $5 for a 2 mg bar.  The immediate risk of using benzodiazepines excessively is accidentally overdosing on the single drug or in combination with alcohol and other drugs of abuse.  There is also a significant seizure risk from abrupt withdrawal when the supply of medications have been used.  The abuse of benzodiazepine like compounds that are more typically used for sleep like zolpidem (Ambien) or eszopiclone (Lunesta) does happen but it is more likely to occur in combination with alcohol for alcohol related insomnia.  A common example would be a person with alcohol dependence who takes zolpidem at night so that they can sleep through the entire night.  Without it they would predictably wake up at 2 or 3 AM from the withdrawal effects of alcohol.  Chronic use of benzodiazepines whether by prescription or acquisition from illegal sources can lead to tolerance and chronic withdrawal symptoms that can last for months if the drug or medication is stopped.  That fact alone should be considered as part of the risk of taking benzodiazepines - even in the situation where the person does not have an addiction and has anxiety that they do not believe can be treated by any other means.  In my experience, I am not sure that kind of anxiety exists.

Another common problem with benzodiazepines is that they can be psychologically debilitating, even if the person affected never takes the pill.  It is all part of the behavioral pharmacology of addicting drugs.  It usually starts out with a panic attack.  That panic attack can result in people going to the emergency department once or twice because they believe they are having a heart attack.  Somewhere along the line a physician prescribes alprazolam to take "in case of a panic attack."  That starts to happen and even if the panic attacks are rare, brief, and situational - the person affected starts to believe they need to carry alprazolam around with them wherever they go "in case" of another panic attack.  They may not have had a panic attack in years, but they are more anxious about whether they are carrying a pill when they get on a plane, cross a bridge, etc.  The pill have taken on Talisman-like features based on their using it for a condition that for most people fades away over time.  Some  who don't know the sequence of events might suggest "what's the harm" if somebody develops such a belief system around a pill.  In my estimation the harm is that the person's normal conscious state has been transformed and they have exchanged one form of anxiety for another.  The debilitating effects of anxiety depend on the illusion that your life needs to be modified in a certain way to accommodate it.  Proving to yourself that is not true is one of the best ways to adapt.        

Despite those reservations, I have prescribed a lot of benzodiazepines in my career.  They are very good medications to use in controlled environments for acute alcohol and sedative hypnotic withdrawal, acute seizures, catatonia,  akathisia, and various agitation syndromes associated with acute psychosis and mania.  The goal is typically to get the patient off the medication before they are discharged and to avoid treating patients with addiction with benzodiazepines.  Benzodiazepines are also useful for the first month in treating panic attacks, but that typically takes a lot of work.  The work involved is convincing the patient that a medication that seems to work rapidly is not a good one to take for the long haul.  The other dimension that is operating here that is rarely commented on and never explicit is whether the person receiving the benzodiazepine enjoys taking it.  Medications that are potentially addictive lead to an array of problems that are not there with drugs than are not addicting.  The main one is that they tend to be viewed as solutions for everything.  Instead of just anxiety or panic people will take them for insomnia, stress, or just to wind down at the end of the day.  Medications that reinforce their own use have the problem of inventing new uses that they were never prescribed for and that can lead to escalating doses of the medication.  In some complicated situations benzodiazepines are added to treat anxiety.  They have been used in psychiatric patients with multiple problems and been shown to add no benefit.  They are commonly added to multiple medications including opioids in patients with chronic pain with no additional benefit.

Benzodiazepines are a big problem in primary care.  The NSDUH survey illustrates that most people with an addiction are not aware of it and further that only a small minority seek treatment and find it.  That same survey suggests that about 1.5 million Americans start using tranquilizers and sedatives (they do not have a unique benzodiazepine category) for non-medical use very year.  Even if it is apparent to a primary care physician and their patient that an addiction to benzodiazepines exits, there are significant obstacles to reversing the process.  Although there are protocols for slowly tapering the medication on the Internet, it takes a very highly motivated person and ideal circumstances to accomplish this.  Outpatient detox from urgent care, the emergency department or an outpatient clinic is problematic because the same medication that the patient is not able to control is being given to them to self administer at home.  It is common that the detox medications are all taken the same day or in some cases at once.  Structured detoxification in the American health care system is practically impossible to find, especially in the case of benzodiazepines that require careful attention to seizure prevention, the prevent of withdrawal delirium, and adequate treatment of chronic withdrawal symptoms when they emerge.  Some primary care clinics are taking the preventive approach of not starting benzodiazepines in the first place.

There is a lot of resistance to the ideas of addiction docs when benzodiazepines and their long term effects are discussed among physicians.  There is always a physician who claims that they have successfully treated a person with an alcohol use disorder with benzodiazepines or they have people who have stayed on low doses for decades in order to treat their anxiety.  I see the failures.  It leads to the question of how many people are capable of staying sober, not developing a tolerance to benzodiazepines, and not experiencing a negative impact on their life.

As far as I know there are no good studies that address that question and I would not expect that there will be.  Any study that allowed subjects to mix alcohol, opiates, and benzodiazepines would be unethical and should not be approved by any Human Subjects Committee.
