Therapeutic Alliance - A Better Diagram
I posted on the therapeutic alliance about 5 years ago. The goal of that post was to point out how psychiatric treatment occurs - specifically the idea that the physician and the patient need to collaborate and define a set of diagnoses and/or problems to work on. They have to agree on the problems and also the plans to resolve (or not) resolve them. In the case of a chronic illness with no clear resolution, the goals are focused on optimizing function. The is basically the ideal treatment model for any physician and any treatment - the only difference is that psychiatrists are trained to attend to the relationship between the patient and the physician in very specific ways. That includes the concept of transference and countertransference or the emotional reaction and associated thoughts of the patient to the physician and and the physician to the patient based on their past experiences. By attending to those patterns psychiatrists can develop insights into what is unfolding in the relationship and in some cases use defensive patterns to assist in the diagnosis and treatment process.
I had a few ideas about how I wanted this diagram to differ from the diagram in my previous post. First, I wanted it to reflect treatment continuity. Ongoing treatment is a dynamic process of multiple events across time in the case of ongoing care. It can also involve single cross sectional interventions that require a patient to complete a prescribed treatment and contact the physician if the problem is not resolved as expected. There are several hard stops to a medical treatment process - cure, improved function without cure, increasing disability, care refusal, and death to name a few. I decided to leave those implicit and not alter the basic diagram. Second, I thought that triangles demarcating the physician-patient decision space would be a good idea because they are more open structures and were used in a recent example of how graph theory may be useful in neuroscience. Third, I wanted to avoid jargon. There are numerous conceptualizations of the conscious state of the patient and the physician and what that implies for the communication - but I distilled it down to the communication and collaboration parameters as noted above. There is implicit informed consent in this model. There are far too may people who see physicians and adopt a passive role. In some cases they request that the physician make important decisions for them: "What would you do if you were me?" The role of the physician is to communicate the information that the patient acts on with all of the attendant risks.
The general model is a good one for all medical specialties. Psychiatrists are be trained to attend more the the relationship and overcome obstacles to treatment. A basic example would be the person who consults with a physician but who is skeptical of the physician's motivations or intentions. In many cases this results in a disagreement and the relationship is terminated without the patient receiving treatment. A psychiatrist should be capable of recognizing what is occurring in the interview and at least being able to point out the reality of the situation to the patient. That reality is depicted in the diagram at the top. I frequently tell people that I have no interest in telling them what to do or even prescribing a medication that they do not want to take. My appropriate role in the model is to give them the best possible medical advice about resolving problems the we both agree on and that might benefit from treatment. It is their role to decide among the options and consent to treatment. Not consenting to any treatment is always an option.
The model also implies that both parties are competent to interact and make decisions. In the case of physicians, states have a vetting and licensing process that is focused on public safety and it does a good job of removing most unsafe or incompetent physicians. In the case of the patient, there are various contexts in which substitute decision-makers are engaged in the process including guardians, conservators, and judges. The legal process to make that determination varies widely from state-to-state and even county-to-county within the same state.

Medication Reconciliation
The Medication Reconciliation Process |
In my 22 years of inpatient experience, I have a lot of experience with this process. I would be the recipient of shopping bags full of medications and learn that some patients were taking greater than 20 medications at a time. Most of my time on inpatient units, I was in charge of reconciling all of the patient medications - medical and psychiatric on the patients I admitted and discharged. In extreme cases this process alone could take an hour on either end. It got a lot worse over time because more people were inserting themselves in the process. Pharmaceutical benefit managers learned to demand an entirely new prior authorization process, even for medications that the patient had been taking for years - at the time of discharge.
The reconciliation process has several modifications based on the care model. For example, in less acute care settings where physicians are not present in the facility at all hours, on-call staff call in and do remote medication reconciliation. Before the EHR that would involve a discussion with nursing staff who would review the medication, the patient's status and put in the orders. The physician would countersign these orders the next day. In current EHRs, there is a med reconciliation section and there may be an expectation that the reconciliation occurs at the time of admission. Nursing staff will typically enter the medications from available bottles or pharmacy records. The physician has to pull up the record remotely, review the patient's status with nursing staff, and sign off on the entered medications. In some systems, only the basic prescription is ordered and the physician will have to complete numerous fields before the inpatient orders are complete. Modern EHRs invariably include drug interaction software with very low thresholds and all of those warnings need to be clicked through and dismissed before the patient's usual medications can be resumed. It is a very slow and inefficient process compared to before the EHR.
One of the rationalizations for the MR in the EHR is patient safety. Regulatory bodies like the Joint Commission are very big on safety factors and they should be. The EHR was supposed to greatly reduce errors due to illegible written orders, but in this case the physician was giving verbal orders to nursing staff. A quick glance at the graphic at the top of the page illustrates some of the thought and decision making that needs to go into this process. There is really no known way to make it fool proof. Subjective determinations about medications and medication safety are being made at every step of the way. Errors in MR still occur largely because of the assessment required by nursing and in this case psychiatry. The easiest way to conceptualize this is to think about people who take prescriptions and whether they take the medication exactly as it is prescribed on the label. The commonest problems involve patients taking their medications at the wrong time or all at once. Often they have been advised by their physician to make a change but the prescription has never changed. In many cases they have stopped the medication and want to restart it. The prescribing physician may not know that the patient is using alcohol, other substances, or nutritional supplements with the prescription. Continuing medications, stopping them or modifying them requires significant clinical judgment and there may be a lot of uncertainty about the history obtained.
Medication reconciliation is a complex and potentially lengthy task. It works best with experienced nursing staff who can get the best information to the prescribing physicians and then physicians who have good clinical judgment and flexibility to adapt to changing histories. It is a potential area for artificial intelligence applications. AI could assist nursing staff without replacing them. We need an optimal algorithm and a full description of the decision space associated with this process. Most importantly we need computer applications that support staff rather than getting in their way and requiring staff support of their own.
One of the most interesting aspects of the current conceptualization of medication reconciliation is how it is perceived by administrators and regulators. The idea that medications can be entered into a piece of software that is essentially a word processor and that makes things right is almost magical thinking to me. All of the hard work leading to that conclusion (see graphic and beyond) is not only ignored - but nobody seems to get credit for it. It is the old rationalization: "If it isn't documented it didn't happen." This is clear proof that most of what happened isn't documented. If would be impossible to function if it was. At some level it appears that all of this hard work was produced by the EHR and not physicians and nurses. Credit to the geniuses who came up with the software and the administrators who decided to put it in. How did we ever practice medicine without them?
We end up documenting what we are told to document and it is a poor substitute for what actually happened. Some of the underlying reasons for that documentation are almost always political.

CPAP Follow-up - Reinforcing Daily Use
I posted on obstructive sleep apnea (OSA) and continuous positive airway pressure (CPAP) last year and it was well received. Since then I have given out a lot of advice on CPAP based on that post and in general to people I have consulted with. I continue to encounter all of the problems that I mentioned in the original post. The message that I am continuing to give people is that they cannot view CPAP as an option. It may not seem like it but it is a critical intervention to prevent the cardiac and metabolic complications of obstructive sleep apnea. There are several of them and they are severe and potentially life shortening. Anyone with this diagnosis owes it to themselves and their family to make CPAP work to avoid the morbidity and mortality associated with OSA.
It is very common in my practice to do my standard sleep assessment and hear that a person was diagnosed in a sleep study and that CPAP was recommended but for various reasons they are not using the machine. I frequently hear about how the patient just "throws it off in the middle of the night" and how they "can't stand to have anything on my face" even in the case where they were diagnosed with severe sleep apnea. Comments like those seem to understate the seriousness of the problem. In many cases, insurance companies have asked for the machine back because the record on the SD card in the machine shows that it is not being used. A person sitting in front of me with untreated OSA is complicated because their physical health is compromised and the immediate complications of untreated apnea and hypertension also compromises their psychiatric care. The OSA and daytime somnolence becomes insomnia and that person may expect medical treatment for insomnia. The prescription of sedating drugs is actually not a good idea for people with sleep disordered breathing. The same think is true for hypertension. There are several medications that can make hypertension worse and that I would not prescribe to people with uncontrolled hypertension. Despite those qualifiers - I see medication and doses that I would not prescribe being given to people with untreated OSA. It is untreated largely because the person does not give CPAP a chance.
Here are a few tips that I give people that they have found to work. I am not working in a sleep lab or clinic so I am seeing them after the study has been does and after they have seen a wide range to technicians who were supposed to help them with mask fit and instructions on how to use the machine.
1. Try various masks and types of CPAP -
A lot of people try the full face mask and throw it off repeatedly at night and decide that's it. If feeling confined by a mask is a problem there are smaller modified masks and nasal CPAP. Try several until you find the one that works the best.
2. Use humidification -
It is surprising how many people think that they will save time by not using the humidification system with the machine. Not using the humidification is another sure way to not tolerate CPAP. Maintain and adjust the humidification for maximum comfort as you are adjusting to CPAP.
3. Make sure there are no air leaks -
In order for CPAP to work there has to be air pressure transmitted into the upper airway to maintain a splinting effect and prevent obstruction. Air leaks put that pressure at risk and can prevent the effective use of CPAP. Trying to find air leaks can be frustrating because after the fitting occurs by the technician or respiratory therapist there are problems at home associated with sleep positions. With the wide array of equipment available it is very unlikely that you will not be able to find a device that works, but in some cases it may take a while. An APAP device with a readout each morning (see graphic) will tell you if there have been any significant air leaks (100% mask fit = no air leaks).
4. Get a modern APAP machine with feed back -
APAP is an abbreviation for Automatic Positive Airway Pressure. This machine is able to sense increasing obstruction and adjust the pressure. One of the main advantages is that a lower baseline pressure can be used and then as any obstruction occurs the devices increases the pressure to overcome it. Standard CPAP devices have the pressure set based on the original sleep study. In the case of significant obstruction that could mean a constant high pressure. Constant high pressures can lead to some side effects such as ear pain from pressure effects. The really strong point of APAP devices is that they are generally much more sophisticated pieces of equipment. They can make the data available over the Internet to a sleep medicine physician who can remotely adjust the settings based on downloaded data. They also allow the patient to download their data each morning via a smartphone app (see the above graphic) so they know the hours that they wore the device each night, what the pressure settings were, and how many apneic/hypopneic episodes occurred (AHI or Apnea/Hypopnea Index) per hour.
5. Optimize your sleeping position and preparation each night based on the APAP readout -
The modern APAP allows the individual patient unprecedented control over the treatment of sleep apnea. With the feedback every morning they can be assured the device is working. In the previous example, I showed a patient with increasing upper airway obstruction who eventually had some episodes of atrial fibrillation. He had no idea that his system had airleaks and his AHI was increasing until he developed the atrial fibrillation. With a new APAP system he would have had immediate feedback on day 1.
Sleep positions can also lead to better APAP/CPAP performance. With the APAP device, feedback will be there within a few days if side sleeping is better (lower AHI) than back sleeping. Looking at the readout of an AHI of 1.3 from Monday in the above example, this patient determined that by sleeping on his side he had consistently fewer episodes that if he slept on his back where his AHIs were all in the 3-5 range.
The final advantage of knowing that there is an APAP device out there allows the patient to advocate form themselves. I don't know if it is widely known but there are clearly some health plans who only provide CPAP devices to patients diagnosed with OSA. APAP devices are more expensive and based on what I have written it is clear that they are superior devices.
6. Oral appliances for OSA are inferior to CPAP on measured outcomes like AHI-
I updated this post to include a comment on oral appliances (OA) for CPAP based on a question that I received. I commonly see people who dislike CPAP and use the OA instead. They claim that is "works better" than CPAP but I doubt it. It does improve snoring and can reduce the AHI based on that improvement. The problem is the improvement in AHI is generally not nearly enough to be considered an adequate level of treatment (AHI < 5) (1). For that reason, expert guidelines recommend the OA for snoring alone or OSA in the case that the patient is intolerant of CPAP(2). Advertisements for a dental approach to OSA are commonplace and usually cite the years of experience of the clinician as being the determining factor. I would recommend considering a sleep study with the OA in place to see just how much the AHI had improved. In the case of the APAP machine you can read the number off your smartphone app every morning. Use those numbers to determine the best treatment for your condition.
If you have been newly diagnosed with OSA and prescribed CPAP - be sure that you get a complete discussion of CPAP versus APAP and why your doctor is recommending one over the other. Ask your sleep medicine physician the ideal solution rather than what your insurance company covers. If cost is the only limiting factor - used and resanitized equipment may be an option.
The treatment of OSA with CPAP/APAP has never been better. Make sure that you get a machine and a system that you are comfortable with and that works. APAP devices can give you consistent feedback that is easily accessible. There are some ways that you can hack a CPAP device and read the information on the SD card, but it is much easier to pull up the data with an app.
The immediate daily feedback that you have a working device and the lowest possible AHI is strong reinforcement to keep using it.

HITECH Editorials in the NEJM...
Since my Labor Day message to colleagues dovetails so well with these editorials, I did not want to miss the opportunity to comment on them. They appear to be written by people with policy interests in this information technology takeover of clinical medicine. They are mildly critical but totally miss the mark on what a catastrophe this government roll out has been. The question any taxpayer should ask is why any other outcome would be expected. Software and network implementations world wide and at the level of the US government have led to colossal failures. Multibillion dollar investments that at some point were abandoned. The only difference in this case is that the government is not the actual client. The federal approach to health care - apart from the brief foray of FBI agents raiding physicians offices to see if they made any coding violations is to set up payments for proxies and let them hash things out with providers. The primitive approach of marginal incentives that are really weighted as penalties is supposed to facilitate the whole mess. The mess would get implemented either way if you ask me. There are tens of thousands of executive and mid level health care executives chomping at the bit for a project like this to mismanage. And they have mismanaged it well. Government leverage makes it difficult to refuse.
The initial editorial by Washington and co-authors (1) focuses on the success of getting hospitals and physicians on the electronic health record (EHR). They present a graphic showing the steep increase in EHR use over the 2004 to 2015 decade. The acute care hospital curve ends at essentially 98-100% for certified EHRs and office based practices are at 90%. The article rightly points out that physicians have borne the brunt of the implementation and how physicians are frustrated by the lack of "actionable information generated by these systems". The article discusses the need for the "seamless flow of electronic information" in a couple of places. It describes how EHR could be useful in research. It ends on a vague note that there is still a lot of work to be done and maybe that will happen some day.
The second piece by Halamka and Tripathi (2) starts out on a more realistic note. Top down implementation gave physicians inadequate tools and then blamed them for being reluctant. Technically physicians were not reluctant because they did not have a choice. In most systems, administrations made all of the purchasing decisions, overhyped the software, and let it be known that contrary opinions were never appreciated. It was up to physicians to learn how to use the stuff no matter how time consuming it was. They point out that some measures were enacted on top of the clinical workload that made the situation worse. They include the longest sentence I have recently seen in a journal article but it does cite a fair number of the problems a lot of the problems:
"Soon physicians were expected to provide high-quality and empathic care in a 12-minute visit while weaning themselves from paper-based workflows, entering the numerous structured data elements required for meaningful use, rolling out new HIPAA privacy notices, implementing security protections for new electronic data, learning and incorporating new ICD-10 billing codes, and convincing their patients to use patient portals and secure e-mail, all while avoiding safety and malpractice issues." (p 907).
At one point they make the argument that health care organization have moved to "value-based purchasing". Was that applied to the EHR? Is there anyone today who would suggest that any EHR that is currently sold in this country is a value based proposition or is there as a result of HITECH legislation? In their conclusion they suggest that now all of these systems are installed - the government can afford to pull back simplify requirements and let market effects shape some of the metrics like interoperability. They suggest that returning control to the customers is a path to "recapturing the hearts and minds of our clinicians."
The government heavy aspect of these editorial pieces cannot be denied. It is more of the same "we are from the government and we are here to help you whether you want us to or not." Here are a few aspects of this roll out that the HITECH legislation either missed or made a lot worse:
1. Incredible cost -
Enterprise wide systems are incredibly expensive both upfront and for the annual licensing and maintenance fees. That does not include any modification of the system - that will typically cost more. Once a health system has bought in - it is difficult to shop around and come up with a better deal. In some areas one company has a monopoly on the enterprise. In many cases the systems are marketed as being a lot more easy to use than they are. Support is huge in the implementation phases and drops off in a hurry. Subsequent modifications - even if they are easy to make cost large sums of money. In some cases the vendors demonstrate whiz bang technology like seamless integration with voice recognition systems. The customers often find out that those options don't work well with their systems or are available as a high priced option.
In many organizations the EHR budget (combined with other federal costs cutting measures) is a fixed drain on the budget. If revenues fall, lay offs can occur just to keep the EHR running. In private practices, the up front and monthly licensing fees are no less of a burden. There are some "free" EHRs that are funded by advertising or research but no standard comparison or guidance for any clinic that needs to implement one. The total budget of these costs would be interesting to see, but I have never been able to find a good reference. Health systems typically describe their margins in the low single digits. If that is true and EHR system costing tens of millions up front with tens of millions in maintenance costs is clearly a tremendous drain on the system.

If that is true and EHR system costing tens of millions up front with tens of millions in maintenance costs is clearly a tremendous drain on the system.
2. IT implementation is poor -
I don't know what percentage of physicians has seen their EHR rolled out in a way that does not optimize clinical utility. Working physicians need the most rapid route to incorporate the EHR into their work flow. That includes software that works, software that is efficient, and ideally software that is smart enough to allow individual physicians to analyze trends in the same patient or groups of patients that will allow better diagnosis and treatment. The IT implementation is also frequently biased toward administration rather than clinicians. Many clinicians are surprised to find that someone is counting their mouse clicks as a way to measure productivity and the EHR charts they access are monitored. This is another significant cost that nobody ever seems to discuss. The most egregious implementation error is when a software change is made on the fly and the physicians are given a heads up with no training. They are expected to learn the software change with no training. I have always found the illusion of assistance with the EHR interesting. For the first few months there are always superusers and the factory reps clamoring to help you out. They gradually fade into the background and you are left with a very poor piece of software.
3. Software quality is poor -
As far as I can tell current EHR programs are designed to deliver lab and imaging data, generate documentation and reports, and perform a billing and coding function. They do a fair job with the labs and imaging details. Documentation is very labor intensive and poorly done. It adds hours per day to the physician's work flow and has necessitated the hiring of scribes and retired physicians just to keep up with the documentation tasks. It is common that EHRs cannot be accessed by outside physicians and when that happens - the printout sent to those physicians is poorly structured and extremely content poor.
On the authorship side - a basic goal should be to produce a document fairly quickly that appears to have been written by an intelligent being. As anyone who has read EHR entries or reports that is not typically the case. There are extremes at either end. You can find notes that are basically a series of check boxes or you can find 18 page notes where the author imported everything that they could into the note because that is one of the few things (in some EHRs) that you can do quickly. Neither approach is helpful in terms of continuity of care or developing rational treatment for a patient. Having used EHRs for the past 15 years - I can attest to clunky editing and incompatibility with voice recognition systems as being major drawbacks. The text fields of some EHRs only work with their own microscopic and very slow editing tools. It is impossible to set a cursor anywhere in the field to produce the document. Using this twenty times a day when you are used to working with functional word processors is maddening. Some systems of care set a font that looks like it is out of the 1950s and that is how the final document appears.
Every physician was appointed (under penalty of law) to be their own billing and coding specialist. Sure every hospital and clinic has some billing and coding specialists but today they are there basically to audit the work of physicians. In the EHR this translates to a tedious search for the diagnoses, listing them in the right priority, and signing off on the diagnostic and billing codes. This can take up to an additional 20 mouse clicks per encounter. Even if you can do that in 2 minutes - times 4000 encounters per year - that equals another 133 hours per year. That is work added just to maintain the EHR. Before the EHR, billing and coding could be completed in about 10% of the time.
All the time physicians are engaged in these inefficient EHR based practices they are hearing how the EHR is such an advance in efficiency and productivity.

4. Hardware infrastructure/software is running 24/7 -
Before the modern EHR, there were a limited number of workstations per hospital and most of them were shut down at night. Now there are thousands of workstations and storage arrays in large organizations running 24/7. They can't be shut off because of frequent software updates. Nursing and medical staff can easily be observed spending most of their workday at computers rather than talking with patients and families. Before the current EHR, physician would typically look at a computer screen to review the labs and possible the MAR (record of meds given). Now starting at a computer screen most of the time is the norm. The EHR dominant approach has increased the electrical bill and reduced time spent with patients at the same time.
5. A question of security -
There have been well publicized leaks of large numbers of patient files and more recent ransomware attacks. Security in most software systems has historically been an afterthought. I have not seen any specific problems with EHR software but this tip sheet from CMS points out the potential complexity of the situation. The security problem is also more urgent for healthcare sites that are under more stringent privacy requirements like 42 CFR Part 2.
Those are a few of my ideas about the rapid deployment of the EHR. Unlike the authors I am very skeptical of any drastic improvements on the horizon. If you can't make an EHR that will produce a coherent report with information content at least equal to an old admission or discharge note that is a major problem. If you can't produce an EHR that allows for some intelligent analysis of data without going through the entire record and reading every text note that is a major problem. Sure - access to labs is nice, but we had computer access to labs before the EHR. Patient access is also nice, but let's be honest - it is limited and doesn't address what patients really want - quality health care.
About the only thing that I agree with the authors on is that the physician needs to be put back into the loop. But that hides the very basic fact that physicians were intentionally taken out of the loop thirty years ago when politicians decided that they could be replaced by managed care administrators.
When you look at it from that perspective the massive problems with the current EHR - make perfect sense.

The Equifax Hack - Implications for Corporate Medicine
A couple of days ago it became general knowledge that Equifax, one of the major credit reporting agencies in the US was hacked and information on up to 143 million people was exposed. To make matters worse, the theft occurred from the company's own identity theft monitoring division called TrustedID Premier. Like most identity theft prevention companies they charge a monthly fee for monitoring your credit transactions and monitor credit card transactions by number. They generally store more personal identification information than is found on a typical credit report. According to Bloomberg financial news Social Security numbers, addresses, driver’s license data, and birth dates were available to the hackers. It took a few days but the agencies eventually picked up on the fact that Equifax was going to provide a year of free credit protection in return for a waiver that the person getting the protection was not going to sue the company. The Bloomberg piece quotes an attorney saying that Equifax could be facing and $70 billion in claims and a multibillion dollar class action lawsuit has already been filed. It goes on to point out that the consumers are limited by arbitration, but in practical terms they are also limited by the sheer scope of trying to collect damages from massive corporations.
I have followed consumer reporting since it all started back in the 1970s. Originally it was just one company and the data was held in a safe. With the evolution of information technology in the 21st century the landscape has evolved into three national credit reporting agencies Equifax, Experian, and TransUnion. There are longstanding concerns about the accuracy of the data they keep in credit reports, the rating system, consumer access, and dispute resolutions. The fact that all of the information is stored under Social Security Number identifiers is significant for two reasons. One is the promise that Congress made to the American people when Social Security was introduced - the the Social Security Number would never be used as a national identifier. At the most it would be used within the government for identification purposes. Today all credit reporting information is linked to SSNs and the numbers are bought and sold on the black market by the tens of millions. Reason two is that this is this wholesale loss of control over the SSN has been the single most important cause of identity theft.
According to the US Department of Justice - 17.6 million people or about 7% of the US population over the age of 16 was a victim of identity theft in 2014. Although half of these incidents are rapidly resolved with minimal losses the scope of the crime results in total losses to victims of $15.4 billion. The DOJ study shows that social consequences of the theft (life stress) are a direct correlate with the length of time that it takes to resolve the incident. Commercial losses are estimated to be about twice of the loss to victims. The typical way that a victim of identity theft learns about the problem is that they are notified by a business. There is no standard protocol for dealing with the problem. A minority of people report it to the police and if they do they are likely to receive a police report number. Businesses in general were very lax in doing anything about the theft. The usual recommendation is complete the affadavit that the consumer did not take the money himself, but now hacking and identity theft is so common that the federal government has a special website to be of assistance called IdentityTheft.gov.
Most Americans would find that the wholesale facilitation of identity theft would be infuriating enough on its own merit. But consider for a moment that they general processes that resulted in this problem are generally applied to any number of businesses including health care. A few of the common points are listed in the table below. The only possible difference is that data breaches of health care systems are much more common.

I never cease to be amazed at how passive Americans are when it comes to allowing elected officials to barter way their privacy rights and money to businesses. The credit reporting industry did not exist before a few entrepreneurs convinced Congress it was a good idea and and the legal and regulatory landscape was set to to favor those businesses to the point that they are essentially monopolies. With few exceptions, the consumer needs to pay for the information that they are collecting on him or her if they are interested in the reports and then again if they are making a significant financial deal. They are not allowed to opt out of a system that puts them at risk all of the time. It is easy to see how these systems engender a fatalistic and in some cases nihilistic attitude in many Americans.
That is not likely to change until elected officials stop treating their citizens like they are cannon fodder for the businesses they invented in the halls of Congress.

Why Most People Don't Have A Mind For Medicine
The inspiration for this post was a story I just read about the "victims" of the crackdown on opioids. A number of chronic pain patients were described who were only able to get pain relief from opioids. They discussed being limited to arbitrary reductions in medications or monthly limits imposed by politicians. In some cases the people taking pain medications were being treated like criminals. They don't like being treated on the basis of people who are addicted to opioids. I did a more extensive search and there are several articles out there like this. The general tone of the article is that there are tens or millions of people out there with chronic pain and that since many of them need opioids for chronic pain aren't we overdoing it a little with the restriction on opioids? Why should good people suffer just because some addicts misbehave and die?
Some of these articles attempt a semblance of balance. They discuss the timeline of the opioid crisis based on policy changes and pharmaceutical marketing. They may get the opinion of some experts than generally falls along polarizing lines. In the end the reader is generally left with a definite viewpoint on what might be the right or wrong approach to chronic pain and the opioid crisis. There is never an explicit statement about right or wrong approaches being the way we got into the opioid crisis in the first place. Medicine is not a a field that you can generally approach with a pre-existing right or wrong bias - at least not for the majority of patients.
Most medical care is directed at a collection heterogeneous disorders spread across the entire population. Each of these conditions has numerous etiologies and no clear cure. That means from a medical standpoint it typically takes a number of trials to see if something works. Since only a fraction of the target population responds to the intervention and a significant fraction of the target population does not tolerate it - the interventions are generally seen as being weak across the entire population. That supports odd arguments like: "Antidepressants don't work" or "Beta blockers don't work for hypertension" or "Thiazide diuretics should always be the first line medications for hypertension".
It is also very tempting to look at the entire heterogeneous population and think: "Now we have a medication that can treat everybody. This is the magic bullet for this disorder". There are really very few medications that work that way. The reason for the less than robust response blockbuster drugs is quite simple - a significant number of people typically do not respond or get side effects to the point that they want to discontinue the medication. That negative response to medication is typically the main limitation when it comes to the overall effect of a medication on any population. In my experience about 1/7 people cannot tolerate an SSRI type antidepressant medication due to side effects. An addition 2/7 will not get an adequate therapeutic response. On the other hand the 4/7 of the people that respond may feel much better and notice a complete remission of depression or anxiety symptoms. Looking at the entire population the overall effect of the medication is not robust, but that does not mean that it might not be a life changing medication for some.
Opioids present a much different landscape because in many people they reinforce their own use irrespective of whether the medication works or gives that person significant side effects. You read that correctly. I have had people tell me directly that they got absolutely no pain relief from an opioid but they liked taking it so much they continued to get the prescription filled. I have had people tell me that they got significant side effects from opioid medication but they kept taking it because they liked how it made them feel. Keep in mind that there is always a range of these effects but I have never heard people describe these experiences with SSRI antidepressants. The mere taking of an SSRI antidepressant does not reinforce continued use.
This is the special dilemma with opioids and all medications that reinforce their own use (benzodiazepines, stimulants). When a person says that they need to keep taking that medication - what does it really mean? I will be the first to admit that they may need to take the medication and have treated chronic pain patients for years who were taking opioids. They were still in pain to some degree but they also believed the opioid was providing them with some degree of relief. The only visible sign that they could take opioids on a chronic basis was that they did not escalate the dose and did not get additional opioids or addictive drugs from other medical or non-medical sources. The obvious question in this case is "Why don't you just increase the dose of opioid to get rid of the pain?" The answer is that there is no medication - not even opioids that completely alleviate chronic pain. I have had many acute pain sufferers tell me that they did not get much relief from acute pain with opiates until the non-specific effects like sleep took over.
Another factor to consider is that most chronic pain patients who come to addiction treatment centers feel markedly better and in less pain when they are tapered off opioids and placed on non-opioid medication for pain. People are often surprised to hear that, but based on what I just said it should not be that surprising. If you are taking a medication that will not completely eliminate chronic pain, has a lot of side effects, and biases you into taking it and ignoring those side effects - how can you not feel better without it?
The final piece of the equation is addiction or severe opioid use disorder. At this stage - the problem is compounded by the fact that a person needs to take the medication in order to function on a day by day basis. If you happen to be a person with chronic pain - not being able to function in addition to the chronic pain puts you in an impossible situation. That is especially true if you are escalating the dose of medication in order to try to recapture the original high, cope with an emotional state, or get some sleep. In many of these situations the person will find themselves "cut off" from the clinic they attend because they have exceeded their prescribed amount of medications. Because that precipitates acute withdrawal they may seek prescription medications from a non-medical source or start using heroin.
I hope that I have been able to convey the complexity of the situation with opioids for a chronic wide scale problem as opposed to other medications for similar problems. The stimulus for this post is the usual swing in journalistic opinion with complex problems. I was going to title the post: "Why journalists and politicians can't practice medicine". Complex chronic problems in medicine cannot be oversimplified into binary solutions at this point in time. Researchers are currently developing the tools that will allow us to identify subgroups in these populations and subject people to less trial and error. At some time in the next 10 years, I expect that we will be able to rapidly identify who might be able to take opioids in a non-addictive manner and who will not be able to. We might even have better medications for chronic pain that are safe and non-addictive by then.
In the meantime, a rhetorical approach casting some people as victims and others as villains is unproductive and stigmatizing. As I tell my students it is the difference between drawing inferences about people in a large city based on the amount of addiction there. Twenty years ago in that large city children going to school would have to walk past three or four drug dealers. As a result urban addiction rates were much higher than rural addiction rates. Now that the rural kids have to walk past as many drug dealers, people in rural settings are addicted to heroin and dying of overdoses. Exposure to drugs rather then moral superiority is the limiting factor.
To do well in medicine a physician needs to have good probabilistic thinking. A lot of that process is acquired rather than learned on a rote basis. Errors in this decision making process are almost guaranteed, but the only real problem are the physicians who seem to error all of the time. That turns out to be a minority of physicians. I expect that this group has difficulty managing both the treatment probabilities and interpersonal dynamics required to treat chronic pain, recognize addiction and implement the appropriate interventions.
One thing is for sure journalists, politicians, law enforcement, and insurance companies do not do a better job than the majority of physicians. It is a major mistake to think otherwise.

Happy Labor Day VI
I missed my Labor Day message last year for some reason. I must have been too burned out. Burnout has been a big theme in the physician community in the last several years. It is almost like it is a new discovery or another new epidemic. Now we have detailed comparisons of degree of burnout by medical specialty and even some country to country comparisons. The curious phenomenon about burnout is how physicians are blamed for it. The typical intervention is to have a "course" on how to "handle" burnout. You know mindfulness, meditation, yoga, and time management. There is never any focus on the fact that physicians just work too hard because they have to work free for so many people. Managed care companies, pharmaceutical benefit managers, government bureaucrats at various levels, and their own employers have come to expect that American physicians have nothing better to do than devote their time and energy to the betterment of those collective businesses. By that metric physicians are the most exploited employees in the USA. There is no other group expected to work for so many businesses for free.
Don't get me wrong. I am not saying that physicians are not paid well. I am saying that according to the studies I read they are being paid for anywhere between 50-75% of the time they work. Even the time that they are being paid for is deeply discounted. What other group of professionals in the USA is expected to work on an arbitrary productivity scale that varies greatly from payer to payer and has a superimposed global budget and federal incentives and penalties superimposed on top of that? Only physicians work in that environment. Only physicians are expected to teach future medical professionals for free. Another one of those cases where the the term "professionalism" can be marched out and used against you. An example: "You can just pick up this course for the medical students or residents. It should not take much time and I know you like to teach. They want you to teach." The next several weekends (whether you are on call seeing patients or not) will be devoted to to coming up with PowerPoints. Lectures and seminars in medicine these days don't happen without the ritualistic exchange of PowerPoints. In the process PowerPoints get blamed. I actually like PowerPoints if they are done correctly. I think they are unfairly blamed when the burden to suddenly produce them is displaced onto the medium rather than the process.
But the focus of my missive today is not burnout or the root cause of excessive uncompensated work. It is one of the sources of uncompensated work and that the the electronic health record (EHR). The attitude toward the EHR has shifted in a direction that I have promoted for over a decade. When the group I was working for was presented with the EHR and trained on it, I knew it was a problem from the start. We were moving from a hospital wide system that was basically for entry of medication orders by health unit coordinators, vital signs, labs, and nursing notes. All of the progress notes were dictated or hand entered. At the end of the day I printed out the MAR (record of medications given) for each of my patients and double checked all of the medications they were getting. The MAR was a single page table showing all of the medications in the left margin and day columns to the right with times of administration. It was all dot matrix printing - so not as stylish as modern printouts.
Back at the time when politicians were overhyping the EHR and how it would save the health care system hundreds of billions of dollars - I did a little experiment with one of my new hospital admissions. I decided to read all of the outpatient medical notes to see how many significant medical diagnoses were being carried over in the EHR. At the time we were online with the new system for about 8 years. It took me 4 hours to find and read all of the notes from Internal Medicine, Endocrinology, and Cardiology. There were 236 notes in all. But in the end I noticed that 10 significant diagnoses had been dropped somewhere along the line. Nobody ever seems to want to acknowledge the complexity in medicine. As people get older they accumulate an incredible number of medical problems and in some cases the only indication is a very long list of medications that they are taking. They have been seeing an equally long list of physicians truncating that list of diagnoses because of time constraints. In the EHR you eventually end up looking at a very short list and need to reproduce a comprehensive evaluation from scratch. So much for the time savings of the EHR. Even the politicians are quiet on that one for now.
A new EHR experiment happened to me just recently. I still treat medically complex patients and often receive them from acute care hospitals where they may have been in intensive care units. Since many of them were taking various psychiatric medications, I felt obligated to see what the intensivists, cardiologists, pulmonologists, and gastroenterologists all had to say about these medications and whether they complicated critical care or ongoing care of the chronic medical problems. I want to see the results of ECGs, labs and imaging studies. I want to know if the patient received any of their usual medications when they were in the ICU or general hospital. Before there was an EHR all of this information was contained in about 10 very readable pages consisting of the admission note, discharge summary, MAR, and a couple of sheets including the actual ECG tracing and lab reports.
For the event in question I read through the EHR printout. It was 48 pages long. It contained limited data. Blood pressure trends and readings were not printed even though that was one of the critical parameters being followed. The physician notes were jumbled paragraphs considerably less that traditional reports. The bulk of those notes consisted of checklists and imported data in different fonts and margins. The appearance was chaotic. Who uses 14 point Courier font in documents these days? I haven't seen that since the days of the telegraph. In that entire 48 page document there were about 6 lines in a cardiologist's note that made sense so I locked onto those for my report.
I was less optimistic about Phase Two. I have been working in my current position for about 7 years and during that time I have requested MARs on hospitalized patients about 50 times. I have received exactly zero. In this case for some reason it went through. I received a 60 page fax that was the MAR. The patient was critically ill and delirious at one point, so there were five different infusions used in intensive care spread out across many of the pages. The composition of the solutions were listed and the specific rates of infusion. If I wanted to know the exact amounts that the patient received - it was up to me to figure it out. Two critical factors from the MAR that were not evident from the EHR printout. First, the patient was much more critically ill than described in the EHR printout. Second, none of the maintenance psychiatric medications were given. Total time to figure all of this out - 60 minutes. In addition to the read of the EHR printout and interview - total time for the evaluation and report was 2.5 hours.
It is impossible for physicians to do a good job of patient care without all of the material I reviewed in this case. On the other hand, there are few places in the USA where the physician has 2.5 hours for each new evaluation. That is how you end up with truncated problem lists, partial medical care, and physicians staying in clinic 3 hours after everyone else has left. Without the data there is not enough information for the physician to have a decent informed consent based discussion with the patient on the new set of risks associated with a critical illness.
The real culprit here is the fact that physicians have lost control of their profession. We have had an overhyped, inefficient, ridiculously high-priced piece of software foisted upon us by politicians and the businesses that they support. It is really no better than personal database software that I was using in the 1990s and that software produced a more readable and coherent report. The only reason the software works at all is because there are a million physicians out there with work arounds and doing the uncompensated hard work necessary to keep it afloat.
There is no better topic to comment on this Labor Day. This is my wish to all of my colleagues trying to avoid repetitive stress injuries from the mouse clicks and typing necessary to support EHRs everywhere (I had to switch to my left hand about ten years ago).
Happy Labor Day!

Blood Pressure
Blood pressure is an important topic for psychiatrists and all physicians. The prevalence of blood pressure problems especially hypertension is high in the United States and has significant associated mortality and morbidity. Many psychiatric medications affect blood pressure and some blood pressure medications like beta adrenergic receptor blockers, central alpha adrenergic receptor agonists, and alpha-1 adrenergic receptor inverse agonists have psychiatric applications. In addition, blood pressure irregularities are noted in major toxic reactions to psychiatric medications like serotonin syndrome and neuroleptic malignant syndrome. Hypertension is a contraindication to the use of some psychiatric medications and parameters need to be placed for their use. All of these considerations would seem to make it obvious that frequent and consistent blood pressure measurements should be a part of psychiatric practice - but they are not.
Various problems with obtaining blood pressures occur in psychiatric practice. Practice settings are part of the problem. In some clinics, depending on the resources blood pressures may not be measured at all. I have received patients from some of these clinics who were treated with medications that cause hypertension or hypotension and found that their blood pressures were never checked. I have worked in clinics where the only way that I could obtain a blood pressure or pulse reading was if I took it myself. I have worked in other settings where blood pressures were taken, but I had no confidence in the numbers. I found myself interviewing the patient and trying to piece together why their blood pressure and heart rates were elevated at some times but normal in others. The only adequate assessment of the situation is that attention to blood pressure and its measurement in psychiatric settings is uneven and may be uniformly poor.
That is why an article in The Journal of Clinical Hypertension (1) caught my eye. In the student the authors looked at 159 medical students and how they measured the blood pressure of a simulated patient against an 11-element skillset on BP measurement. Only one student out of the 159 demonstrated all 11 skills in simulation. The specific tasks are listed in the article and have to do with patient preparation, positioning, and the actual measurement task itself. Some common errors in any of these areas can lead to significant differences in systolic and diastolic blood pressure measurements. Those errors alone especially those in cuff size selection, arm positioning and patient readiness can lead to consistent false measurements in blood pressure. As an example, I have assessed a week or two of blood pressure measurements in the mild hypertension range and after correcting the measurement techniques found that the subsequent week was all in the normal range. This study illustrates an unacceptably high variation in these skillsets in medical students. I am not aware of similar studies in practicing physicians.
The second article (2) is an encyclopedic reference that is a scientific consensus statement by the American Heart Association on High Blood Pressure Research. This reference will answer any possible question about blood pressure measurement. A valuable resource from this site was a resource that provides a very extensive list of validated home blood pressure devices. It is possible to make recommendations for accurate and cost effective devices or provide the link to patients who want to explore the possibilities.
I encourage psychiatrists everywhere to make sure that blood pressures and pulses are being taken regularly and accurately. The buck stops with the physician doing the assessment and treatment and in my opinion it is impossible to practice psychiatry without regular blood pressure measurements. In addition to monitoring the cardiovascular status of the patient and the response to prescribed medications it provides the opportunity to diagnose a disorder that causes significant cardiovascular and cerebrovascular disease and reverse that process.
Know the 11-element skillset on blood pressure measurement.

Dementia Prevention And Substance Use Disorders
Dementia from Addictive Compounds |
As a geriatric psychiatrist and an addiction psychiatrist, what I see happening in both professional literature and lay literature is mind boggling. There is a clear bias advocating for the benign and even therapeutic effects of alcohol and addicting drugs. What most articles omit is that the health effects of alcohol are limited to no more than two standard drinks per day for men and one drink per day for women. The drinks cannot be all taken on the same day. The limits are per day not per week. Most of the evidence also suggests that the alcoholic beverage should be wine rather than beer or distilled spirits. Recent studies suggest that of the 70% of Americans who drink - about 1/3 of them are probably drinking in excess of those amounts. Doing the arithmetic that amounts to about 56 million people. Even a low percentage of brain injury will result in a significant number of cases od dementia. Moderate to heavy drinking (3-12+ drinks/day) carries the associated risks of high carbohydrate intake and sedentary life style. It is very common to find that moderate to heavy drinkers stop their usual outdoor activities and exercise and spend a lot of time watching television. This can lead to obesity, glucose intolerance and dyslipidemia and in the worst case scenario metabolic syndrome. All of those consequences lead to increased risk of cardiovascular and cerebrovascular disease.
There are addiction risks with alcohol consumption apart from atherosclerotic heart disease. Alcohol is proarrhythmic and doubles the risk for arrhythmia. In one large Danish study (11) they noted that alcohol intake and a history of atrial fibrillation was a risk factor for ventricular fibrillation. Some authors view alcohol use a risk factor in preventable atrial fibrillation. In clinical practice it is very common to interview patients with atrial fibrillation who notice that during times of heavy alcohol use they can sense that they are in atrial fibrillation and they spontaneously convert to sinus rhythm as their blood alcohol levels drop. Atrial fibrillation is a causative mechanism for embolic stroke and associated cognitive disorders.
The direct toxic effect of alcohol on the brain has been debated for years. Amnesia from Wernicke-Korsakoff syndrome is a known diagnostic entity related to thiamine deficiency associated with excessive alcohol use. It is probably underdiagnosed in most populations compared with postmortem diagnoses of the specific lesions consistent with Wernicke-Korsakoff syndrome (WKS). A large number of people with alcohol use problems have demonstrable cognitive effects on testing as well as structural and functional brain imaging brain imaging studies suggest some effect on brain structure. The lack of a pathological lesion has led some to suggest that this is a non-specific effect, but it is very likely that there are several variants of cognitive dysfunction related to alcohol use that are not associated with WKS (12). On a clinical basis it is very common to see patients with subjective cognitive impairment that typically involves working memory, declarative memory, and executive function. In treatment setting where abstinence from alcohol is assured many of these problems seem to clear up after about 60 days of abstinence. But there are also populations of people with varying degrees of anterograde and retrograde amnesia that is not as dense as expected with full WKS. Many of these patients are seen in treatment settings and never referred for comprehensive assessments of their cognitive disorder. To my knowledge there have been no studies looking at the issue of whether or not partial amnestic states correlate with WKS lesions at autopsy.
The problems with recognizing and treating cognitive disorders associated with substance use problems are exemplified in the first few paragraphs about alcohol. They are no less important for other commonly abused substances. In the case of stimulants, amphetamine analogues are known neurotoxins. Studies by Volkow and others have shown persistent changes in dopaminergic neurons up to 15 months after the last use. This may correlate with a persistent attentional deficit that leads patients to conclude that they now have attention deficit disorder. Additional brain insults from hemorrhagic strokes and cardiovascular problems associated with long term stimulant use are common. Stimulants are well known precipitants of acute myocardial ischemia and brain complications from hypoperfusion and emboli. Acute hypertension and tachycardia are part of the acute intoxication syndrome that can lead to hypertension and hemorrhagic stroke. This recurrent cycle leads to commonly observed complications of cardiomyopathy in the 4th and 5th decades of life and heightened risk of ventricular arrhythmias and cardiac arrest.
The graphic at that top of this post is not exhaustive - but point out some significant acute and chronic complications of drug use that can lead to permanent brain injury. These mechanisms cannot be overlooked as avoidable causes of dementia. I will be trying to elaborate on this graphic in the future to look at developing a review in this area. Any acute acre and addiction psychiatrist is probably more aware of these syndromes and complications because they are encountered in clinical practice. I have not seen any formal estimates of the fraction of dementia cases are preventable by avoiding these compounds. The largest fraction of dementia cases would likely be attributable to the most commonly used drugs - tobacco and alcohol. Drugs that kill more people acutely on a proportional basis like stimulants and opioids probably leave fewer survivors with dementia as a complication.
Contrary to the conventional wisdom these days - avoiding dementia is another strong argument for a sober life style.

The calculation for the following observation:
Recent studies suggest that of the 70% of Americans who drink - about 1/3 of them are probably drinking in excess of those amounts. Doing the arithmetic that amounts to about 56 million people.
321M(current US population) - 80M (population less than drinking age) x 0.7 (percentage of population that drinks) x 0.3 percentage of excess drinkers = 56 million people.
