Drinking Your Way To Your 90s.






The headlines recently have been unmistakable:

Drinking alcohol key to living past 90, study says

Drinking Tied To Long Life In New Study

Drinking alcohol increases longevity more than exercise, according to study

Alcohol more important than exercise for living past 90, study claims


Could these headlines be true?  After all, wasn't there a recent headline that said drinking alcohol was the largest single modifiable risk factor for dementia (1)?  Buried in some of those headlines are also secondary stories about political decisions that did not go well for the producers of some alcoholic beverages.  France's Health Minister Agnès Buzyn - a physician stated recently that alcohol is alcohol.  She went on to say that contrary to what French citizens are taught to believe about the health effects of wine it is no  different than drinking beer or distilled spirits and it is bad for health.  I think that we have been in the midst of a tremendous  amount of hype about alcohol, the specific types of alcohol, secondary natural products, the purported metabolic effects and the effect of alcohol on longevity.  The current headlines were the only ones I can recall where the positive effects of drinking alcohol was estimated to be on par with exercise.

I come at the problem from the perspective of an acute care and addiction psychiatrist. For 22 years, I worked at a tertiary care center that was also a Level 1 Trauma Center and it contained a burn unit.  At one point our medical director surveyed our admissions and determined that at least 50% across the entire hospital were there because of drugs or alcohol.  We saw every type of injury and chronic illness due to intoxicants and the patients with those insults often had markedly shorter life spans than expected.  How could alcohol use extend life?  Why was it seen as a common finding? Most importantly - why were all of these headlines surfacing right now?

Some of the articles named Claudia Kawas, MD and her work in the 90+ Study and Leisure World Cohort Study as the source for the headlines (2-4).  The Leisure World Cohort Study (LWCS) followed a group of 8,371 women and 4,828 men from a media baseline age of 74 for a period of 28 years or until death.  The group was located in a retirement community and were described as predominately white, middle class and well educated.  They were sampled at intervals with questionnaires that asked about their dietary habit including beverage intake in terms of alcohol and caffeine containing beverages and other types,  a number of activity levels, and total amount of exercise.  A large number of papers resulted from this study and are still being written as the continuation study of the members that survived into their 90s.  Dr. Kawas gave a presentation at a recent American Association for the Advancement of Science (AAAS) meeting on some of her findings and that appears to be what the headlines based on.

 From the LWCS group, there were several notable findings.  In terms of activity level (2), any activity of 1/2 hour per day or more reduced mortality risk 15-30%.  A broad range of exercise of various levels of intensity and whether they were done inside or outside.  Level of activity at age 40 was a predictor of activity in old age.  Relative Risks (RR) for all cause mortality were calculated for the activities and their duration. as well as the time spent.  After 3/4 of an hour per day the RR effect tapered off.  Sedentary activities like watching television had no significant impact on the RR.  The greatest observed risk occurred when activity levels were reduced due to injury or illness.  They found no survival advantage for a high activity level (1+ hours per day) compared to a moderate level of 1/2 to 3/4 hours per day.

The same group looked at the issue of alcohol intake in the LWCS group.  In their introduction they note that 4% of the annual mortality in the world is caused by alcohol.  They review some of the previous literature and the purported J - or - U shaped mortality curves for alcohol consumption - meaning higher mortality rates for abstainers, lower mortality rates for moderate drinkers (1-2 standard drinks per day), and higher mortality rates for higher levels of drinking. The response choices on the survey were for 1, 2, 3, and 4 or more drinks per day.  They also broke the sample down based on their responses drinking surveys in 1992 and 1998 to to stable non-drinkers, stable drinkers, starters, and quitters based on comparing their survey answers.  Three quarter of the sample drank.  Two drinks a day conferred a 14-16%  in decreased mortality irrespective of the type of alcohol.  At follow up there were more non drinkers than at baseline (36% versus 26%).  The quitters and starters acquired the expected mortality risks in each group.  They conclude that there was a small beneficial risk of alcohol on mortality of about 15% but qualify the result based on the study limitations.

The final dimension in this sample of the LWCS paper was a look at non-alcoholic beverages and caffeine content.  They looked a coffee, decaffeinated coffee, black or green tea, cola drinks (sugar or artificially sweetened), other soft drinks and sweetener combinations, and the amount of chocolate eaten (daily versus a few times per month.)  They found that there was a U-shaped mortality curve for caffeine consumption with peak protection at about the 100-399 mg/day.  They also found that consuming as little as one can a week of artificially sweetened soft drinks had a small increased risk of death (11-24%).  They looked at specifics and determined that 1-3 cups of regular coffee/day reduced mortality risk by 5-10% and drinking decaffeinated coffee or tea reduced risk by 5-9%.   Drinking sugar sweetened cola - had an 8% lower risk of death.  Infrequent chocolate users also had a reduced risk of death (3-9%).

Taken all together these three papers suggest that moderate levels of alcohol, caffeine, and activity are all consistent with longevity.  In order to look at the alcohol findings in perspective, I searched the literature for a meta-analysis of all of the alcohol x longevity studies and came up with an outstanding paper by Stockwell, et al  (5).  In it the authors look at and extensive analysis of existing alcohol effect on mortality studies and initially duplicated a J-shaped mortality curve based on 87 studies they included in their analysis.  They went back into that sample and corrected for abstainer biases such as including including former and occasional drinkers in the abstainer category.  They model four types of abstainer bias in their in the paper.  When those corrections are made or when only very high quality studies are used - the purported mortality advantage of moderate (1-2 standard drinks per day) - disappears completely.  I could not find any data from the LWCS studies used in this meta-analysis.  According to the author's selection criteria the LWCS data probably would have been eliminated because it was a cross sectional study.

That alcohol is not a heath food should not come as a surprise.  Any cohort of drinkers in their 90s suggests to me that they are biologically selected to survive the alcohol and that is probably why they are drinking into their 90s and not because of it.  Since the activity, caffeine, and diet soda effects noted in this study were collected using similar methodologies, that can be a cause for concern. The authors were careful to cite supporting data  and discuss the limitations.  Observational studies like the LWCS and 90+ Study add to the literature but it is necessary to keep these findings in perspective and consider the potential biases of the design.

At this time I have not found a similar meta-analysis for each of the other cases (activity level, caffeine consumption).

The Abuse Potential of Gabapentinoids





I first started prescribing gabapentin in the 1990s, as part of an early attempt to see if it worked for bipolar disorder.  It was an off-label approach and did not have that indication.  At the time anticonvulsant approaches to bipolar disorder (valproate, carbamazepine) were being heavily used.  I was following a number of people who could not take lithium and on anticonvulsants and they seemed to do surprisingly well.  Gabapentin seemed to have significant advantages in terms of toxicity, it was well  tolerated by most people.  Unfortunately, it was completely ineffective for bipolar disorder and I stopped trying it almost immediately.

The next off label application that surfaced was for chronic pain.  Any psychiatrist is exposed to a number of patients with chronic pain or chronic pain and addictions, and it became apparent that it was being used successfully for chronic back pain, chronic headaches, and post herpetic neuralgia.  Over the next decade, gabapentin and then pregabalin was prescribed for chronic pain indications and people seemed to do reasonably well with it - even at relatively high doses.

At some point, physicians working in detox and the addiction field started to use gabapentinoids for chronic pain, anxiety, and withdrawal.  It is not uncommon to see patient with all of these problems who is not able to tolerate antidepressants for those symptoms or who needs more immediate relief.  In fact, in residential addiction treatment it is common to see patients come in on high doses of gabapentin for chronic back pain.   They are there for treatment of an opioid use disorder, but during that time have not escalated the gabapentin dose.

In the literature reports of gabapentin misuse have been surfacing over the past 5 years (1-7).  A large review (4) suggests that 1.3% of the treated population is at risk for gabapentinoid misuse with the number being much higher is some populations such as opioid users.  There is a report (3) that patients with opioid use disorder will attempt to augment the eurphorigenic effect of methadone in a similar way that they use benzodiazepines.  Benzodiazepine use with methadone in methadone maintenance clinics is a chronic and at times lethal problem.  There is a report from Norway (5) that gabapentinoids may be useful is reducing benzodiazepine use.  The report generally suggests that the abuse potential is low and greater for pregabalin than gabapentin.  There is an insurance database report (6) that looks at an overuse metric comparing gabapentinoids to other abused drugs.  Goodman and Brett (7) comment on the epidemiology of gabapentinoid prescribing, specifically an increase in gabapentin prescriptions from 39 million in 2012 to 64 million in 2016 with an associated doubling in the sales of pregabalin during the same period.  They attribute the increase to attempts to treat chronic pain without opioids in primary care, suboptimal non-opioid medications (acetaminophen and NSAIDs). They cite mixed evidence in clinical trials, side effects, misuse or diversion, and an excessive focus on pharmacological measures for pain as being concerns.       

Are there biases in these report?  There certainly are.  I don't have access to the full text of the most comprehensive paper (2), but I would be interested in looking at the actual numerator and denominator for their numbers and how much was based on actual pharmacovigiliance/pharmacosurveillance as opposed to case reports, case series and reports of complications.  The other issue is that all of these papers seem to come from the same publisher.  I have not encountered that before.

The only study that I could find that looked at the direct question of concomitant use of opioids and gabapentin came from Canada (8).  It studies a large group of patients on a database that records the prescriptions and looked at all opioid users that died of opioid related causes between 1997 - 2013.  The big picture is that there were a total of 2,914,971 opioid users during the study time frame and 6,745 died of opioid related causes.  Then by selection criteria they identified 1,256 cases and matched them to 4,619 controls. They defined gabapentin exposure as concomitant gabapentin use in the 120 days preceding the index date.  They also looked for a dose response relationship of gabapentin doses considered as low (<900 mg daily), moderate (900 to 1,799 mg daily), or high (≥1,800 mg daily).  They also did a comparison with nonsteroidal anti-inflammatory drugs (NSAIDs) used as an adjunctive pain medication instead of gabapentin.  Their results are summarized in the following tables excerpted directly from the article (click to enlarge):

 
As noted from the data and analysis, 12.3% of the controls and 6.8% of the cases were prescribed gabapentin in the 120 days, representing a 50% increased risk of death in the gabapentin treated cases.  In the case/control comparison both groups have roughly the same levels of mental illness but the case group had higher utilization of antidepressants (all types), benzodiazepines, and other drugs/CNS depressants. They were also taking substantially more high dose opioid therapy (>200 MME).  Higher dose gabapentin nearly doubled the risk. There was no added effect from NSAID use.  The authors conclude that caution needs to be exercised in deciding to prescribe this combination (opioids + gabapentin) and that if that decision is made it needs to be carefully monitored.  From my perspective I had some concerns about the controlling for benzodiazepine use in the case/control comparison and did not see any risk attributable to benzodiazepines.  The authors do cite a reference that led to FDA warnings about the benzodiazepine-opioid combination. 

Given the concerns about gabapentin why use it at all?  The main reason is that it is effective for some of the most difficult problems in medicine.  It is very difficult to see people with extreme anxiety and insomnia go for weeks without sleep and experience continuous panic attacks all day long.  When a person stops taking benzodiazepines that they have been taking for years that is a frequent result.  The same is true for people who have decided to stop drinking and suddenly have very high levels of anxiety and insomnia now that their baseline anxiety is back.  More to the point, unless something can be done to provide them with timely relief, relapse to drug and alcohol use is certain.  Finally does high levels of abuse by some patients with addictions suggest that the medication is unsafe?  It is probably safer then other medications in this population and extremely safe outside of those populations.  In either case safety depends on whether there is a physician involved or the medication is acquired from nonmedical sources.   

Standard practice with gabapentin should be to tell all patients (in addition to the usual discussion and detailed information) the following information.  I point out here that I do not prescribe pregabalin:

1.  Take this medication exactly as it is prescribed.
2.  Do not accelerate the dose of the medication.
3.  Do not mix this drug with alcohol or any other intoxicants or street drugs.  If a relapse occurs call to discuss and set up a plan as soon as possible.
4.  Do not stop the medication abruptly it needs to be slowly tapered.  There is a seizure risk if it is not.
5.  This medication is potentially addictive to some people. If you notice any tendency to take more of this medication than prescribed contact me immediately.
6.  This medication is monitored on the state Prescription Monitoring Program and all prescriptions are recorded even though it is not technically a scheduled drug at this time.

At least that is the way that I think it should be handled.  If I was still seeing a lot of patients with chronic pain on moderate to high doses of opioids I would add in a line or two about the the Canadian study (9) and greater chances of death from the gabapentin + opioid combination.  In my current practice, psychiatric treatment is split off from buprenorphine detox and maintenance treatment - but I still see a lot of patients on buprenorphine + gabapentin and can attest to the fact that in a controlled environment we have not observed the complications suggested by the Canadian study over a period of months.  None of these patients receive benzodiazepines or sedative hypnotics beyond a period of detox.  In fact, doing that study might be a significant contribution to the research.  It also probably means that those patients when they are discharged should hear that the risk of taking that combination may increase substantially in the outpatient setting.

There is plenty of politics and confusion surrounding the gabapentinoids issue.  It should not be surprising that this medication is showing up in the toxicology of opioid overdose victims. It should not be surprising that some people try to get "high" on it, even though the people doing that do not have typical ideas about the utility of medications. It should not be surprising that people try to use gabapentin like benzodiazepines to augment the effect of what they are using to get high especially opioids.  It should not be surprising that when some people decide to stop buprenorphine or methadone that they will buy somebody's gabapentin to try to treat withdrawal effects.  It should not be surprising that in some areas it is currency on the street (What can I get for a month's worth of gabapentin?).  It should not be surprising that it has become a political football in the social media on pain ("See it's not opioids as the problem - it is gabapentin") or the social media on weed ("See these are Big Pharma solutions, marijuana is much safer").  It should not be surprising that you can read about it on drug culture web sites where everyone is an expert pharmacologist and provides you with anonymous advice on how to get high. It should not be surprising that you can buy it online and have it delivered to your door, although you can never really be certain that it is the same stuff you get at Walgreens.  I am always amazed at how easy it is to sell some Americans drugs, if they think there is the slightest possible chance they can get high on it. That is also why it should not be surprising that children and teens will take it out of medicine cabinets - use it to get high and brag about it even though there were probably not high at all.

The features about the gabapentinoids that make sense to me is that they are medically useful  and have low toxicity, for people with nearly impossible problems in desperate situations.  It is a less toxic drug on the street than those mentioned in the above paragraph. Even then these drugs need to be carefully prescribed and closely monitored.  And even then some people will escalate the dose. There are no perfect solutions in medicine and in this area in particular - nothing seems to be coming down the pike.  The probability statement is always - does the use of gabapentin result in more people with improved symptoms, better quality of life and less addiction?  At this time unless presented with compelling evidence I would say that it does with the qualifier that its application needs to be carefully done by a physician who knows what they are doing and is aware of the potential for misuse. In  the current era, that can all be subject to the next social media fad.

There is not a big push by the pharmaceutical industry at this time to discover a drug that has limited toxicity that can be used for severe chronic pain, insomnia, and anxiety associated with addictive disorders.  There is also the question of what medications are being used for these problems if not gabapentin.  The answer is atypical antipsychotics (mostly quetiapine), hydroxyzine (a first generation antihistamine), and clonidine (primary use is hypertension and opioid withdrawal).  If the comprehensive toxicology of overdoses is available I would expect to see these compounds listed.  In any search of drug interactions both quetiapine and hydroxyzine are flagged as potentially affecting cardiac conduction. Clonidine can cause hypotension if used excessively and rebound sympathetic symptoms (tachycardia, hypertension, diaphoresis).  Looking at that group of medications gabapentin would appear to have the preferred side effect profile.

There also appears to be a big push to make gabapentin a controlled substance according to the Controlled Substances Act (CSA).  Pregabalin is currently a Schedule V drug (see page 14) or considered to have the lowest abuse liability.  Getting on that list depends on how the DEA currently sees the addictive behavior towards gabapentin versus pregabalin.  Putting a drug on Schedule V will probably have no impact on how it is used in medical practice or out on the street.  The fact that pregabalin is ranked so lowly is a sign of regulatory opinion on abuse liability.

That's my current opinion on the topic.  I may add more to this post in the future or to a post I am working on about the basic science of gabapentinoids.

One Small Step For Physician Autonomy




Physicians have been oppressed in the United States for the past 30 years - nearly the entire length of my career. That is not rhetoric. It is a fact. The oppression has occurred at the level of federal and state governments and eventually the businesses that those governments actually support.  A lot of it is documented on this blog and I am not going to repeat it here.  The most recent twist on that oppression has been in the form of maintenance of certification (MOC) actively promoted by the American Board of Medical Specialties (ABMS).  All medical specialty organizations in the United States are members of the ABMS and are forced to abide by its rules.  Some specialty organizations  started their own MOC that did not involve ABMS procedures and they were told they had to all go through the same process.  That process involves testing and intrusive measures into a physicians practice.  It is a major departure away from life-long learning that physicians aspire to and use to shape their individual practices.

The move to MOC was initiated by ABMS on their own and well before there was any debate of the evidence.  As an example, I was board certified by the American Board of Psychiatry and Neurology (ABPN) in 1988.  There was no time limitation on the original certifications until 1990.  I was certified Added Qualification in Geriatric Psychiatry in 1991; but that certification was time limited 1991-2001.  I was re-certified in Geriatric Psychiatry ten years later and that certificate states Recertified 2000-2010.  I was also certified Added Qualifications in Addiction Psychiatry 1993-2003.

Somewhere around the time I was due for certification for Addiction psychiatry, I asked myself: "Why are you doing this?" It costs a thousand dollars to take the test.  The test did not confer any special status, privileges, or salary.  It did not change any study habits at all.  I was still attending quality CME courses, reading the literature, and incorporating it into my practice. I was teaching and that is always associated with needing to know a lot more about current debates in the field as well as the representative scientific literature.  Even though I have never failed one of these board exams, there is a ritual of needing to take time off and study material that may not be immediately relevant to your practice - medical and psychiatric trivia that is an essential part of standardized test gamesmanship.  So I decided no - I am a professional. I am at the top of my game and all indications are that things are going well.  Even if they weren't, a thousand dollar board exam or even MOC procedure is not remedial.  It does not provide any feedback. It is essentially a prep school exercise of jumping thorough another hoop.  You either make it or you don't.  At that time there had been 7 hoops* and that was enough.  I stopped the process at that point. 

My guess is that a lot of other physicians saw the light the same way that I did.  My further speculation is that the ABMS reacted by increasing their leverage first by not issuing lifelong original certifications like they gave me back in 1988 and then making those re-certifications as onerous as possible.  I am not being dramatic when I use the term onerous.  I thought about getting back into the current MOC stream about a decade ago at an APA convention and talked with the ABPN representative at their booth. At the time, he literally could not tell me what I had to do to resume the endless cycle of paying fees and taking tests only that there was even more to do than that.  Not an inspiration to get back into the process.

Since then the ABMS has become much more strident about the MOC process.  They were playing the odds.  Physicians and their professional organizations are generally politically clueless and ineffective.  The best evidence of that is their inability to prevent managed care advocates in both government and business from taking over the field and dramatically decreasing the quality care.  They made arguments about how it was necessary to maintain quality and knowledge in a field.  How does that happen by taking a trivial pursuit style exam with no feedback and a very high pass rate?  How does that happen by basically doing patient satisfaction surveys on my patients - a procedure that is rapidly falling into disrepute in clinical settings. 

In the interest of brevity, I am not going to point out all  of the logical errors or overt conflict-of-interest in the ABMS arguments.  There are many bloggers out there who have done outstanding job of that including Cardiologist Westby G. Fisher, MD, FACC and Psychiatrist Jim Amos, MD.  In the literature the standard bearer against the MOC process has been Cardiologist Paul Tierstein, MD who was instrumental in founding the alternate board certification process through the National Board of Physicians and Surgeons (NBPAS). 

My conclusion after wading through all of the politics for that past decade was to get re-certified though NBPAS for several reasons including:

1.  Meaningfulness -  the existential equivalent of that word meaninglessness has been with me since I read Yalom's classic book Existential Psychotherapy in 1982. Yalom referred to it as the fourth ultimate existential concern - right after death, freedom and isolation.  Becoming a practicing physician is an exercise in delayed gratification.  As an intern and a resident the term "busy work" is used to designate tasks that have to be done but don't seem to advance true knowledge or understanding. It is really not clear what your professional life is going to be like until you are in the field interacting with colleagues and patients and practicing medicine.  Physicians as a group are overachievers, overwork, and compulsively question themselves about their decisions.  They are not work averse at all.  One of the motivators to expend this kind of energy is doing meaningful work.  Dr. Tierstein emphasizes this on the last slide in his lecture.  MOC is busy work and its meaning is arbitrarily defined by outsiders. 

2.  It reflects the original ABMS process - we certify you to go out in the world, practice medicine, and keep up with the theoretical and clinical aspects on your own as a professional.  Working with very bright colleagues providing excellent care for 30 years validates that approach.

3.  It certifies my ongoing work - I hope it is apparent from this blog that I am not a casual reader of the psychiatric literature.  I study it at several levels. I have two rooms in my home that are covered from ceiling to floor with medical and psychiatric literature.  I correspond with interested colleagues around the world.  I attend conferences.  I am working on current research.  I teach. I consider all of this life-long scholarship.  At one point the ABPN suggested they were going to put an asterisk (*) next to the names of lifetime certificate holders unless they participated in MOC.  To me that is an insult to my current work and professionalism. It's like designating me as some kind of steroid user.

4.  The NBPAS certifies continuing medical education credits (CME) - my state medical board asks me to report the total number every three years.  There is a suggestion that they will audit all of my certificates, but in 30 years that has never happened.  NBPAS does not certify you until you meet their CME requirement and send them all of the certificates via their web site.  They have an excellent website that can accept uploads of at least 10 of these documents at a time.  So here is a powerful reason for every state medical board to use NBPAS certification.  It immediately means that CME requirements are met very 2 years and they are certified.     

5.  It reflects what I do in my clinical work - sub-specialization in any field is always controversial.  Does there need to be another division in the field?  Is there enough evidence that it is far enough away from what everyone else is doing to be a separate body of knowledge?  After 30 years of work - I say no.  I still see geriatric patients, patients with general psychiatric disorders, patients with addictions, and patients with medical problems every day.  It's not like I can go to a magical clinic somewhere and just see a patient who only has one problem affecting their brain.  To do a good job, you have to continue to know it all.  It is hard work and there are often not a lot of clear answers, but that's why it is called practice and that's why we love medicine.

6.  It is tremendously cost effective considering what gets certified - the financial incentives for the MOC movement are huge and funded by physicians.  Stepping out of the MOC loop makes a clear statement.

7.  It is view consistent with my political philosophy -   I am from blue collar roots and was socialized to suspect the motives of politicians, businessmen, and even union organizers.  Very little of my experience as an adult seems to counter that perspective.  I see health care being run by the same mechanisms as the financial services industry and not for the benefit of physicians or their patients.  NBPAS certification is an antidote to the ABMS Big Brother approach.  In Dr. Tierstein's video he points out why it is no accident that healthcare companies insist that any physician working for them have MOC.  It is all part of the conflict-of-interest driven ruling class approach to business and regulation that we should expect.

That is why I got the NBPAS certificate.  I understand that there are early career physicians locked into some HMO who are told they need to be in the MOC cycle or they will lose their privileges and job (further evidence BTW of what MOC really is).  I can't understand younger physicians who don't recognize splitting when they see it.  I have read their opinions about how some think they know more than older physicians and how they are more tech savvy and how they are not averse to managed care manipulations.  I will just say that being an expert takes more than writing a smart phone app or thinking that you know every thing in the field after passing the initial board exams.  The true innovators and experts that I know have been doing what they innovated for the past 20-30 years.

The bottom line for this post is irrespective of where you are in medicine, if you ignore the politics you do so at your own peril.

Currently MOC is at the top of that list.

*  The 7 hoops included part 1, 2, an 3 of the National Board Exams to qualify for a medical license and the subsequent 4 certifications and recertifications by the ABPN.  After thinking about this there were actually 8 hoops because there were actually 2 ABPN ceritifying examinations for psychiatry.  Part One was a written exam on psychiatry and neurology including imaging questions.  Part Two was an Oral Board exam that consisted of two parts.  One half of the day was an examination based on an observation of a videotaped interview. The other half of the day was an examination based on your observed interview of the patient.  Part Two had a higher failure rate probably due to a high degree of subjectivity.  I knew people who failed it more than once. So that is really a total of 8 tests altogether.

The NYTimes Editorial On Why Mental Health Can't Stop Mass Shooters -What's Wrong With It?





There was a New York Times editorial titled "The Mental Health System Can't Stop Mass Shooters" dated February 20, 2018.  It was written by Amy Barnhorst, MD, a psychiatrist and vice chairwoman of community psychiatry for University of California, Davis.  Since it popped up it is being posted to Twitter by more and more psychiatrists.  It does contain a lot of accuracy and realism about the issue of assessing people acutely and whether or not they can be legally held on the basis of their dangerous behavior.  Dr. Barnhorst gives examples of people who allegedly make threats and then deny them.  She discusses the legal standard for commitment and its subjective interpretation.  For example, even though a statute seems to have a clear standard they are many scenarios in the grey zone, where a decision could be made to err on the safe side.  That involves hospitalizing the patient against his or her will because the risk is there and their behavior cannot be predicted.  If hospitalized, she anticipates the outcome when the patient appears in front of a hearing officer and gets released.  That last scenario is very real and I would guess that the majority of decisions on the front end in these cases take into account what might happen in court.

If the hypothetical patient did get committed he would not be able to acquire a gun with a functional background check system. That system does not currently exist. If guns were involved in his case before hospitalization, the police may have confiscated them.  Unless his legal status changes they may give him the guns back.  In some cases the patient is told to ask their psychiatrist to write a letter to get their guns back.  I am not aware of any psychiatrist who has done that.  The FBI NICS system lists all of the conditions that would prohibit a point of purchase gun sale (assuming a check is done).  That list includes: "A person adjudicated mental defective or involuntarily committed to a mental institution or incompetent to handle own affairs, including dispositions to criminal charges of found not guilty by reason of insanity or found incompetent to stand trial."   Various crimes including domestic abuse can also trigger a failure of the NICS check and when that happens the gun sale is cancelled.  Unfortunately not all states participate in this check system and there are numerous exceptions if they do.

I have diagrammed the various levels of arguments that apply to a psychiatrist doing a crisis evaluation on a person brought to the emergency department for making threats with firearms.  At the political level there is no nuance.  At this level the degree of distortion is the greatest.  The usual arguments about guns not killing people is a good example, but it extends even this morning to President Trump suggesting that more mental health resources will solve the mass shooting problem, when it clearly will not.  The legal arguments are slightly more informed, but still fairly crude.  Like most legal arguments they threaten or reassure.  For example, most psychiatric crisis statutes hold harmless anyone who reports a suicidal or aggressive person to the authorities.  On the other hand, if a psychiatrist places a person on a legal hold because they are potentially dangerous - it is typically illegal for that same psychiatrist to extend the hold if the court system has not done anything by the time it expires.  The civil commitment system has a way of starting to make decisions based on available resources and in many cases the statutes seem reinterpreted that way.

At the medical level, psychiatrists are left living with the legal and political arguments no matter how biased they may be and trying to come up with a plan to contain and treat the aggression.  It is not an easy task given the resource allocation to psychiatry - but after doing ti for 20 years - it is fairly obvious that acute care psychiatrists know what they are doing.  They are successful at stopping violence acutely and on a long term basis.  Given the legal biases they cannot do it alone.  There needs to be cooperation from the courts and the legal system and some patients should be treated in the legal rather than the mental health system. 




Getting back to Dr. Barnhorst's article one sentence that I disagreed completely with was:

"The reason the mental health system fails to prevent mass shootings is that mental illness is rarely the cause of such violence." 

She cites "angry young men who harbor violent fantasies" as basically being incurable.  The problem with mental illness and gun violence is that it is dealt with at a political level rather than a medical and diagnostic one.  The facts are seldom considered.  There are political factions that see violence as stigmatizing the mentally ill and political factions who want to scapegoat the mentally ill and take the heat off the gun advocates.  The reality is that people with severe mental illness are overrepresented in acts of violence compared with the nonmentally ill population. It is a small but significant number. In studies of mass homicides the number increases but it depends on the methodology.  There are for example school shooter databases that record events as anytime a firearm is discharged in a school.  That results in a very large number of weapon discharges but most where nobody is injured.  There are databases that just list events but there is no analysis of whether mental illness was a factor or not.  In mass shootings in half the cases the shooter is killed or suicides.  Even when the shooter survives the data is affected by the subsequent hearings - so there is rarely a pure diagnostic interview available.  The data analysis depends on making sure that both the events and the mental health diagnoses are as accurate as possible.

The most parsimonious assessment of this data was published by Michael Stone, MD in 2015 (1).  The paper is fairly exhaustive and I am not going to discuss the obvious pluses and minuses.  I do see it as a break from the usual sensational headlines and the analysis of the trends in mass homicide over time, especially associated with semiautomatic firearms - leaves no doubt that this is a large problem.

He identifies 235 mass murderers, and estimates that 46 (22%) of them were mentally ill.  His definition of mentally ill as essentially being psychotic.  He goes on to say that in the remaining fraction and additional 48 had paranoid personality disorder, 11 were depressed, and 2 had autism spectrum disorders. In other words another 26% of the sample had significant mental disorders that were not considered in the analysis because he did not consider them to be psychotic.  Another 45 (19%) has either antisocial personality disorder or psychopathic personality disorder - both mental conditions associated with criminal activity and thought to have no known methods of treatment.  Using this conservative methodology - it is apparent that mental illness in this population is not rare at all.  What should not be lost is that although mass shootings are very noticeable events - they are rare and therefore any overrepresentation of mental illness in this group, is diluted by what happens across the entire population where the majority of violent activity is associated with people having no mental illness and the overall trends in violent crimes are at a 20 year low.

My proposed solutions to the problem of semiautomatic weapon access and mass shooters/murders is approached this way:

1.  Increase the purchase age to 21 years.  Eliminate access to military style weapons.

2.  All purchases must be cleared through the NICS system.  All states must participate. Currently only 12 states participate in full point of contact background checks on every gun sale.

3.  The NICS system should include terroristic threats, stalking, and any gun confiscation by the police because of mental health grounds as exclusion criteria.  In other words, you are eliminated from gun purchases if you have been reported for these problems.  That may sound a bit stringent but I think there is precedent.  You cannot make threats about air travel at an airport.  If you have been charged with domestic abuse (Misdemeanor Crimes of Domestic Violence (MCDV)
 the are special instructions on what it takes to keep firearms from you.  I consider the safety of children in schools to be on par with these two cases (air travel and domestic violence threats).

4.  At the level of law enforcement, any firearms confiscated during a threat investigation should not be returned and that person should be investigated and reported to NICS Database.

5.  Uniform protocols need to be in place for terroristic threat assessment.  It is no longer acceptable to wait for a person to commit an act of aggression before there is a law enforcement intervention.  The person making the threat should be removed from that environment and contained pending further investigation.

6.  On the mental health side - rebuilding the infrastructure to adequately deal with this problem is a start.  Hospitals with large enough mental health capacity should have a unit to deal with aggression and violence.  There should be specialty units that collect outcome data on the diagnoses represented and work on improving those outcomes.

7.  On the law enforcement/corrections side there needs to be recognition that not all mental health problems can be treated like mental health problems.  Violent people with antisocial personality disorder and psychopathy are best treated in law enforcement setting and not in psychiatric settings.  In psychiatric setting they have a tendency to exploit and intimidate the other patients in those settings as well as the staff.  They should be treated by psychiatrist with expertise in these conditions and been seen in correctional settings.  Probation and parole contingencies may be the best approach but I am open to any references that suggest otherwise.

8.  In the early years of this blog - I was an advocate for violence prevention and I still am.  Violence and aggression have the most stigmatizing effects of any mental health symptoms.  I think it is safe to day that most psychiatrists actively avoid practicing in setting where they may have contact with aggressive patients.  It needs to be seen as a public health problem and education and prevention are a first step.

Those are my ideas this morning.  I may add more to this page later.  If you have a real interest in this topic Dr. Stone's paper is a compelling read.  If I find others of similar quality I will post them here.  Don't hesitate to send me a reference if you have one.

The bottom line is that no psychiatrist can operate in the current vacuum of realistic options and hope to contain a potential mass shooter.  And yet there is a clear overepresentation of mental illness in this population.  Some level of cooperation as suggested above will result in a much tighter system for addressing this issue.  We do it in airports and in domestic violence situations.  We can also apply more uniform and stringent expectations to schools.

Drug Marketing In The Post Psychiatric Apocalypse




I saw this drug marketing ad from Johnson and Johnson posted on Twitter today.  Johnson & Johnson is marketing their sustained release version of paliperidone called Sustenna as a way to keep people with schizophrenia out of jail!  I have not been able to find an updated package insert from the FDA at this point but this is from a release on the J&J web site as an indication for the  drug.

"The time to first psychiatric hospitalization or arrest and/or incarceration was significantly longer for people treated with INVEGA SUSTENNA® versus these same commonly prescribed oral antipsychotics." 

I have been posting here for years about the fact that health care businesses and governments have actively worked together to eliminate psychiatric and mental health resources.  That is just a proven fact.  I have posted that psychiatrists have been taken out of the loop so that these same politicians and business leaders can accomplish these goals.  I have posted that the resulting pricing strategies divert any existing resources away from physicians and patients and into the pockets of the managed care, pharmaceutical benefit manager industry, and pharmaceutical companies leaving some patients with very little to live on.  I have posted about how psychiatric beds have been rationed until they are practically non-existent and the admission and discharge criteria altered so that very little treatment occurs there.  And as a final result, I have documented the widespread diversion of patients with severe psychiatric problems to jails.  The largest psychiatric hospitals in the USA are county jails.  I have pointed out how there is a tendency to blame psychiatrists for the mythical shortage of their own specialty and mental health services when any real shortage was planned that way by the same people who have rationed mental health services to the bone.

There are probably just a few people (usually psychiatrists and the families of patients) who know about what happens when the bar is lowered from hospital admissions to arrests and incarcerations.  I have observed first hand what occurs.  The risk to the patient increases exponentially.  Every time there is a confrontation between the police and a mentally ill person the odds are greater that there will be misunderstanding, injury, and possibly death.  I have received many of these beaten up people on my inpatient service when they were brought to the hospital and admitted because they were obviously mentally ill.  The only reason they were brought to the hospital was because of the physical injury.  Otherwise they were on their way to jail.  Once in jail they can get no care or very little care.  It is common that people with mental disorders or addictions are taken off of their usual medications.  They do not receive them in jail most of the time and that can impair their ability to cooperate with law enforcement or work with an attorney to get released.

So jail has become a treatment endpoint on par with hospitalization.  Somebody somewhere must have a number that shows it is much more likely that a person with a serious mental disorder ends up in jail rather than a psychiatric hospital.  I could suggest a number of surrogate endpoints for the next study.  Number of people dead on the street.  Number of people dead because they did not get their insulin or needed medical care for heart or lung disease.  The possibilities become numerous when humane treatment in a safe medical setting drops farther down the list.    

This ad and study as well as the FDA approval marks a new low water mark in psychiatric care in the USA.  I think we can safely say that we are now in a post psychiatric era of care.  An era where the quality measure is keeping patients out of a place that they should never have been put in the first place - the county jail.  The is a palpable new low in the nonsystem of care for the mentally ill.  That new low has been endorsed by a federal agency - the FDA and a pharmaceutical company.  It will probably result in other pharmaceutical companies trying to get the same indication. 

At this point there is no doubt that businessmen and politicians have a stranglehold on psychiatric care.  It has morphed into a landscape that is unrecognizable to this psychiatrist. 

God save our patients and God save us all.

Jeff Bezos Hear My Plea





My latest excursion into direct-to-consumer lab testing concluded about an hour ago (2:30 PM) and it was an unequivocal bust.  I wanted to check three different endocrine parameters that I thought might be important for asthma control - so I went online looking for a way to do that.  I am not a novice in the area.  About 10 years ago I found a local health care system that offered a limited menu of direct to consumer testing.  In other words, you just walk into the lab, check off what labs you want, pay them, and they do the tests.  No calls to a doctors office and the endless telephone queues, no discussions with staff who treat you like you are a demanding patient, no waiting for a call back from the doctor, and no waiting for the staff person to talk with the doctor and then call you back. That is exhausting and a clear impediment to medical care.  The electronic health record (EHR)  "fixes" for this problem are not much better.  I find myself either looking at a list of fairly simple lab tests and visits or signing off on a possible $45 fee for an email if I have not seen the doctor within a certain interval.  That is equally exhausting, especially when I end up clicking on "other" and typing an essay on what I really want.

About 10 years ago,  the first direct to consumer labs became available in the Twin Cites - a metro area of just over 3 million people. There was a very limited menu, but I found it useful to follow Vitamin D levels and discovered that my wife probably did not need to take Vitamin D.  I occasionally checked a few other tests - maybe a total of 5 times in the 10 years.  This time I needed more esoteric tests than were on the list and hoped there was another lab.  I did find it but there were several problems.  The first was test selection and payment.  It suggested that I do it online, collect all of my tests in a cart and check out.  When I did that I discovered that the company collecting my credit card information was not the lab, but some other company I had never heard of.  Was it safe to give them that information?  There was an online chat staff - but she just gave me an 800 number to confirm the company was who they said they were.  I shut it down at that point.

The next step was calling the nearest lab about 9 miles away.  I called several times and left my number.  Nobody bothered to call me back. I finally decided to just drive down there.  They were located in an industrial strip mall - nothing unusual for durable medical goods companies.  I walked into a packed waiting room of about 20 people.  There was a reception window that was never inhabited during the 90 minutes I was there.  Any new customer needed to figure out that they needed to enter their name, birth date, and phone number on an electronic tablet in order to get into the queue.  A phlebotomist came out every 5-10 minutes to call the next customer.  The place had an industrial feel - not unlike an old hospital past its prime.  It seemed like everyone else was bringing in paper work.  My expectation was that it ran like the other place.  Just check off the boxes, pay, and get the blood drawn.  The real conversation went something like this:

Phlebotomist:  "Do you have any paper work?"
Me: "No I thought from the web site that I could just tell you what I want and pay here."
Phlebotomist:  "No - here you need a doctor's order or an account."
Me: "Well I am a doctor can I just give you the order?"
Phlebotomist: "Do you have a prescription pad?"
Me: "No I thought I could just check a form and pay you."
Phlebotomist: "No we can't take any payments here - you have to pay online."
Me: "OK - sorry for wasting your time."
Phlebotomist: "You're not wasting my time. I'm here until 4 o'clock."

It was a total wash.  No lab test and about 2 1/2 hours wasted.

This is where a company like Amazon can really revolutionize health care.  Healthcare companies are doing everything they can to monopolize lab and imaging services.  They have oversold the EHR to patients like everybody else.  I have argued with some of these unfortunate souls that believe the EHR is really going to help them maintain their own private healthcare information and portability.  My description above indicates otherwise.  I also ask them if they still have any healthcare information that they stored on a computer in the 1990s.

The news about Amazon, Berkshire Hathaway and JP Morgan news about their healthcare initiative has fueled a lot of speculation about how that will play out.  My speculation is that Amazon has the current data handling infrastructure to aggregate healthcare just like they aggregate everything else.  The question is what will be aggregated, how will it be aggregated, and what will the regulatory burden be on the aggregation.  Consumers are now considering their personal healthcare information to be their own property.  That is not how the laws are written, but it is a selling point for health care products.  If Jeff Bezos is listening, the low hanging fruit in health care are high margin lab tests, imaging studies, and medications.  Those are the best products to aggregate based on  price comparisons and how easily they are available.  On the back end, there is the question of getting the results to the attending physician and the medicolegal implications of giving abnormal results back to a patient with no commentary.  In Minnesota, the first company I used here got around that by saying that any abnormal tests were run by the laboratory pathologist for comment.

As a physician and consumer, this is the revolution that is necessary.  Many people are perfectly capable of getting maintenance labs or labs of interest when necessary and call their doctor about the results.  They are less likely to keep coming in and seeing a doctor for the sake of routine labs and lab interpretations.  They are less likely to go to traditional hospital and clinics that adhere to inconvenient hours.  This approach would shift some of the cost to the consumer, but the trade off would much better cost and convenience.  An example is the three endocrine tests I was ready to order cost about $230 and they have been available for decades. For the same price, I can get my entire genome analyzed. Lab margin estimates in the news are 10-20%, but I would guess that is on the low side.

All of the current major Internet companies are capable of these changes.  They should also be very competent in producing a much better EHR that works for physicians.  I think that health care regulation and business models are what has been holding them up.  Hopefully Amazon's move will get the rest of them involved and move health care management and funding as far away from the insurance industry and pharmaceutical benefit managers as possible.   

I may still end up walking into an industrial strip mall lab to get my blood tests done - but at least I would know that everything on the front end would have been handled flawlessly and my credit card will take less of a hit.

Sedating Patients For Imaging Studies





An article in this week's JAMA hit me like I was still on my old inpatient job.  It was about the issue of sedating patients for imaging studies.  Quality brain imaging - whether it is an MRI or a CT scan depends on the patient being able to lie very still.  Any movement causes artifact that can obscure critical brain areas of interest.  The reasons for the agitation vary quite a bit based on the population but the agitation is not necessarily any easier to treat.  The setting is often different.

As an example, agitated patients on our neurology service when I was an intern were typically agitated due to brain disease.  One of the first patients I saw was elderly and extremely agitated.  Delirium or psychiatric illness was suspected because of examination limitations.  When I examined the patient in the emergency department (ED) - and did the otoscopic exam - there was a large amount of pus coming out of the left ear.  Subsequent lumbar puncture showed that the diagnosis was pneumococcal meningitis.  Like all agitated neurology patients, the chief resident came by and administered intravenous fentanyl.  The junior resident and I stood by next to the CT scanner in the event the patient became excessively sedated or apneic because of the fentanyl.  Without it the CT scan would have been impossible.  She was subsequently admitted to the ICU and had a very complicated course, but eventually survived and left the hospital.

On the psychiatric side. things are a little bit different.  The indications for brain imaging are all based on psychiatric diagnoses.  The medical status of the patient may be completely unknown, based on their ability to cooperative with a review of systems and physical examination.  In most inpatient psychiatry settings these days the patient has come through the emergency department but the complete diagnostic evaluation is deferred to the inpatient side.  Assessment by the inpatient staff the next day may indicate that brain imaging is needed.  The ability to cooperate may vary from an inability to sit still to overt aggression based on the illness.  It is a common occurrence to get a request from radiology to sedate the patient before they go for a brain imaging study.

The issue from an inpatient psychiatric unit is several fold.  Many of the patients are very vigorous and have no physical illnesses.  The medications used on psychiatric units are not anesthetic agents and they do not work immediately.  Psychiatric units are rarely staffed at a level that several physicians can accompany the patient and give them an agent that would work immediately.  Even if they could - the question would be qualifications to supervise that process. At the minimum, they would need to be qualified to administer that agent and manage a cardiopulmonary arrest.  Finally, there is the hospital wide issue of how much support can psychiatry count on.  Can psychiatry for example request an anesthesiology consult for the purpose of imaging study sedation?

In the case report, an elderly man with a BMI of 39 and an history of stable coronary artery disease presented to the ED with dizziness. He ahd associated hypertension, hyperlipidemia, history of carotid endarterectomy, and obstructive sleep apnea (OSA).  He was treated symptomatically with meclizine and ondansetron but a neurology consultant recommended an MRI scan of the brain. He was not able to tolerate the close confines of the MRI scan and was given 1 mg of lorazepam for anxiety reduction.  Over a period of about 15 minutes in the MRI scanner he became incoherent and eventually unresponsive and a cardiac arrest code was called.

The article reviews the errors made in this case beginning with the administration of lorazepam.  Lorazepam is commonly used on inpatient psychiatric units for detoxification, agitation, and insomnia.  The exact dose in this case is a dose that I have administered many times to patients who were going for imaging studies and it is frequently not enough for that purpose.  In this case the patient has OSA and risk factors such as increased age that place him at higher risk for complications.  In this case the authors suggest the minimal dose and if more is needed to monitor heart rate, pulse oximetry and blood pressure in high risk patients.  I would typically do that by requesting an anesthesiology consult for the purpose of sedating the patient for an MRI scan.

Associated measures of care in  this situation include equipment availability.  They recommend the availability of a fiberoptic bronchoscope in case the patient needs immediate intubation and the intubation is difficult.  They consider it to be a priority in the case of patients who have risk factors for airway loss after sedation.   

The American Association of Anesthesiologists has designated dexmedetomidine as a sedative that does not compromise the cardiorespiratory status of patients.  It is a alpha-2 adrenoreceptor agonist.  I did a search on psychiatric applications of dexmedetomidine and the results of that search can be found here.  The package insert discusses the limited applications of ICU intubation and sedation of non-intubated patients for procedures.   

Communicating the patient's OSA status was also viewed as a key error correction process.  OSA is a highly prevalent condition making it more likely that patients with this condition will be sedated for MRI scans.  The suggest including an OSA section in the MRI checklist.

When I think about how this procedure has been done over the course of my career - it was hardly standardized and apart from my neurology team monitoring critically ill neurology patients inside a CT scanner - little monitoring was done.  About 15 years ago that landscape started to change.  Suddenly anesthesiology consults were much easier to get and much more successful.  That was a great relief compared to a process when additional medications were being requested and nobody was there to monitor the patient.  In a few cases, I called off the scan until adequate monitoring could be established.         

The precautions noted in this case report should be studied by every psychiatrist who finds themselves ordering sedation for MRI scans or other procedures.  It is entirely possible that MRI technology may be available in some hospitals but not the appropriate monitoring staff.

In that case I would recommend forgoing the procedure if all of the recommended staff and equipment is not available.

The Problem of the Drinking Spouse




Any physician treating alcoholism knows this scenario very well.  You have finally convinced a person that they have a problem with alcohol.  They have been in treatment and either using or not using MAT (medication assisted treatment - naltrexone or acamprosate).  They are at the point where they are abstinent many more days than they are drinking.  This is a critical point for many people who are daily drinkers.  As you work with them in trying to define critical factors for continued use they identify: "My husband/wife refuses to stop drinking.  They say it is my problem.  They like drinking and they refuse to stop.  They have alcohol at the house."

There are many variations on that theme.  Some spouses will keep all of the alcohol locked up and imbibe only when the sober spouse is sleeping.  Some will not have any alcohol at all, but continue to drink in social situations accompanied or unaccompanied by the sober spouse.  Some will just resent the sober spouse and the sudden restriction in the couple's social life.  Many couples start drinking to increase their social activity and expand their social contacts.  In many businesses, this level of socialization and the associated drinking is expected.  The associated level of emotionality in the marriage can increase precipitously based on the new expectations of the sober spouse about how things should be to support their sobriety.  The combination of the environmental cues from alcohol and increased emotionality greatly increase the risk for continued alcohol use and make all of these patterns untenable.  Convincing the drinking spouse that their behavior does not facilitate sobriety in the marriage is a difficult task - if it is attempted at all.

Are there any large scale studies that back up those clinical observations?  A certain portion of drinking spouses may respond to clear scientific evidence if they cannot respond to the advice of a counselor or physician.  It turns out that there are and a lot of that work has been done by Kendler and co-authors. 

The most recent paper in JAMA Psychiatry (1) looks at the issue of spousal resemblance for alcohol use disorder.  In the study, subjects were obtained from a generational sample of all people born between 1960 and 1990 in Sweden who were married before December 31, 2013.  They were identified as having alcohol use disorders (AUD) through several databases that looked at medical diagnoses, medication assisted treatment prescriptions (disulfiram, naltrexone, acamprosate) and convictions or suspicions of at least two alcohol related crimes.  That resulted in marital pairs - 5883 where the husband first developed an AUD and 2679 where the wife first developed an AUD.  They note that in marital pairs, first onset AUD was much greater in pairs where a spouse had an AUD than when they did not.

They analyzed the data by two methods.  First, they looked at hazard ratios of developing an AUD relative to a control group matched by sex, birth year, year or marriage, family history of AUD, and parental educational level.  Second, they looked at intraindividual hazard ratios across subsequent marriages and divorces.

In the first analysis, the hazard ratio of AUD in the wife after the husband had an initial AUD was 13.82 dropping to 2.75 over the first two years.  In the case of  husbands after a wife's first registration of AUD the hazard ratio was 9.21 falling more slowly to 3.09 after 3 years.

In the intraindividual comparisons - for husbands moving from a spouse with no AUD to one with an AUD resulted in a HR of 7.02.  Moving from a spouse with an AUD to one without and AUD decreased the risk to a HR of 0.50 for AUD.  The protective effects persisted in the same direction in second and third marriages.  They produced a comprehensive tables of 20 possible combinations of spouses +/- AUDs and list the protective and predisposing combinations.  In each case, whether or not the prospective spouse has an AUD predicts the the probands status.

The authors conclude that this is tentative evidence that a spouses alcohol use status has a causal effect on their spouses drinking.  They suggest the likely processes and suggest that assortative mating is a factor in the large increase in drinking that can occur when a man or woman without an AUD marries a man or woman with an AUD.  Assortative mating has been previously studied by Kendler (4) and is defined as mate selection that depends on similarity across traits - in this case drinking patterns and risk factors for AUD.  It is an interesting concept because it suggests at least part of the mechanism of greatly increased risk in the spouses of drinkers.  A non-drinking spouse with those characteristics may have more credibility as a protective effect, but those specifics are not clear at this time. 

The limitations are discussed in the original paper and I won't belabor them here.  Clearly the study design is an issue.  It is likely that cases were missed.  I have not seen it studied, by my experience with diagnoses and the American insurance system suggests that many people will do what they can to stay off of a database.  I can't imagine that is not also true in Sweden.  They did a comparison of the AUD prevalence of their data to Norway and found the prevalence was lower.  This methdology also focuses on more severe AUD.  I based that on the fact that the DSM-5 committee eliminated legal problems as a diagnostic criteria for AUD based on it not adding much to the criteria because it was associated with most of the other criteria.              

An observation about the study.  It could not have occurred in the United States - at least not on the same scale.  In the US, treatment for alcohol or substance use problems comes under the the auspices of §CFR 42, limiting access to information for research purposes.  Advocates for these restrictions will of course say they are necessary and that people can still release information like they can for any other medical condition - but like most of these regulations there is general confusion and intimidation of clinicians to the point that the extra hurdles necessary to do research are seldom breached.  In the US, in the case of non-public programs like Medicare or Medicaid, all of the data is aggregated by health care system.  In Scandinavian countries all patients are on a single national database.  In the Swedish study, the researchers assigned unique serial numbers to all of the subjects and the ethics committee approval waived consent because of this procedure.

This study gets back to a philosophy of life and the issue of sobriety or at least self-correcting abstinence.  Couples do have conversations about drinking.  They do make conscious decisions about drinking and substance use.  They observe one another when they have become too intoxicated and had significant embarrassment or hangover effects.  If there are no baseline agreements about the use of intoxicants early in the marriage there should be a discussion about self correcting abstinence.  When do we agree to stop whatever we are doing as a couple and reassess our use of intoxicants.  Things do not have to get to the level of an actual alcohol or substance use disorder.

Finally, what about the approach to the couple when there is a clearly defined alcohol or substance use problem?  The couple's dynamic does need to be identified and addressed.  For any physician or counselor approaching the problem is fraught with difficulty.  Spouses tend to be defensive, resentful, and in some cases openly hostile to the idea that they need to stop drinking.  The drinking spouse may see the physician or counselor as affiliated with the nondrinking spouse and that can amplify the resentment and negative emotion.  There are programs with a more neutral response that treats the drinking spouse in an entirely different context and provides the necessary education.  Al-Anon is the prototypical self help program for spouses that attempts to address anger, resentment, and provide a focus on positive strategies.  I am still waiting to see an explicit manual, pamphlet, or book that is focused on why the drinking spouse needs to stop drinking.  If I missed that please send me a link to that resource.   

Before you send a comment on the couple where one person is sober and the other person drinks, I can assure you that I am aware that the situation exists.  I typically see it where the spouses are independent and often have separate social and recreational outlets.  In many cases, one of the spouses works excessively and alcohol use is incorporated into work activities or becomes a ritual on the way home.  The situation I hope to address here is one where both spouses are drinking - usually too much and one of them wants to quit.

I have not seen a lot written about the problem or the solution.

New Twist On An Old Method To Kill The Flu Virus




Right after posting the previous article on the latest confirmation that influenza virus is airborne, I came across and article in Nature that had me thinking back to my childhood.  I remember walking into an insurance office on Main Street in our small town.  There was something strange about the environment.  Up next to the ceiling were ultraviolet lights.  The lights were shielded so that they only reflected up toward the ceiling.  I asked my parents what they were and got the answer: "They are there to kill germs."  My head was spinning from that answer: "There are germs in the air? They are up next to the ceiling? What kills the germs that are down here next to me?" Yes - I was a neurotic little kid.

Over time I learned a little about the nature of ultraviolet light, especially that it could cause eye damage if you looked right at it. As I got into the 1970s, the hippie era, and psychedelia that because less important.  There were UV lights everywhere - blacklight posters and the detergent residues in clothing phosphorescing white light after it has been activated by UV light.  In some environments everyone was bathed in UV light.

Today most Americans are aware of UV light because of sunscreen and eyeglass applications.  Long and medium wavelength (UVA and UVB) and not absorbed by the ozone layer.  It is recommended that glasses block 100% of the UVA and UVB for maximum eye protection.  That can also be designated as UV400 because they block all UV light from 280-400 nm.  The part of the UV spectrum is also important in sunscreens.  UVA penetrates the skin to a deeper level and is responsible for damaging keratinocytes, cataracts and causing premature aging.  UVB is responsible for burning and carcinogenesis.  UVA and UVB are considered both carcinogenic and carcinogenic.  Even those UV light has been known to be germicidal for over 80 years that human toxicity has limited the application.

UVC (100-280 nm) is blocked by the ozone layer and therefore is not a consideration in either eye or skin protection.  It is considered to be the part of the spectrum that is potentially germicidal and that is where the latest application begins.  In this report the authors used filtered 222-nm light sources in an experiment to see if they could inactivate aerosolized H1N1 influenza virus.  They were able to accurately measure the light dose and estimate virus inactivation using an epithelial cell model that measured infected cells by fluorescence.  The authors aerosolized the virus into a UV irradiation chamber.  The chamber had a total volume of 4.2 liters and had a characteristic particle distribution of 87% < 0.3 - 0.5 μm, 11% 0.5 - 0.7 μm, and 2% > 0.7 μm.  Those are characteristic particle distributions of airborne droplets that occur with breathing, talking, and coughing.



An air flow of 12.5 L/min through the chamber was noted and they calculated that this meant a single droplet passed through the chamber in about 20 seconds.  I think that is significant because it in unlikely in a typical building that a person would be standing in an air current moving that quickly. In other words, if the aerosolized virus can be inactivated in an airstream moving that quickly - it might have practical applications in most environments.  The authors were able to construct a dose response curve showing that at a dose of 2 mJ/cm2 viral survival is negligible.




I found this to be extremely impressive work because it clearly shows that airborne influenza virus can be inactivated using a far-UV source that is much safer to humans than previous germicidal UV sources.  Furthermore the sampling and intervention characteristics seem to be very realistic in terms of what might be encountered in public facilities.  The real question seem to be whether any commercially available air cleaner/purifiers come close to matching the characteristic of this experiment.  A preliminary search of these devices shows that the airflow characteristics are typically not listed, very few use far-UVC light sources (most use germicidal 254-nm sources shielded in the device), and none are certified in terms of how much virus they kill. They typically suggest that germicidal UV light is all that is needed for air purification.  There is also the question of whether using a device in your office at work confers any degree of protection once you leave that office and start walking down the hallways.  My speculation is that it would not, but the amount of virus generated in your office may be a significant variable.

The authors themselves suggest that if their results are confirmed far-UVC represent a significant opportunity to limit the transmission of airborne disease and that it could be widely used in medical offices and buildings as well as public areas where disease transmission is common like airports and airplanes.

I am hoping that this areas of research yields rapid results and broad implementation.
