The Art and Soul of Medicine Exist in the Ordinary

Jul 7, 2021

By HANS DUVEFELT

The Art of Medicine is Doing the Ordinary Well

Primary care doctors don’t usually operate any sophisticated medical instruments or perform any advanced procedures. But there is still art in what we do. We take care of ordinary ailments in ordinary people and that can be done well or not so well. There is no obvious glamor in it, but when our prescriptions, basic procedures or simple advice help people feel better, we live up to our own and our patients’ hopes and expectations – and some of the time, we even exceed them.

Art is art, regardless of the medium or subject. Weren’t the old Dutch masters’ most appreciated paintings depictions of ordinary people in ordinary circumstances? Not every artist gets to paint the Sistine Chapel.

So many things in our culture are at the two extremes of poorly done and exquisite: fast fashion or haute couture, drive-up burgers or five star restaurants. Fewer things are made with care by craftspeople for individual users. Medicine needs to be more like that in order to bring real healing in many conditions.

In our everyday encounters with our patients, we are often distracted by things other than what they expect or hope to get from us. We have agendas imposed on us for preventive care and public health purposes. It is sometimes hard to do your best if you can’t concentrate on the issue at hand. Art requires focus. It is not a casual endeavor. It requires attention to detail, just as much as a vision of the big idea. It is – or should be – for each of us, in order to do our best, to find the balance between those two aspects of our work.

The Soul of Medicine is Connecting as Humans

We are not technicians. We treat the whole person, because most things in primary care are diseases that affect more than just one organ. We now also, again (historically), accept that diseases of the body may have their root causes in what we call the soul. In order to know and treat another person, we must show our own. Only if we do that will we learn enough to be of any real help to the patient who hopes to trust us enough to take our advice. We must create connection.

Medicine is Child’s Play: Where’s Waldo, Spot the Difference and Whack-a-Mole

Oct 30, 2018

By HANS DUVEFELT, MD

I started writing a post a few days ago about the challenge of quickly finding what you’re looking for in a medical record. As I came back to my draft this morning, it struck me how much this felt like some of the games my children played when they were young. This got me thinking…

Where’s Waldo: Finding what’s important in the medical record

I did a peer review once of an office note about an elderly man with a low grade fever. The past medical history was all there, several prior laboratory and imaging tests were imported and there was a long narrative section that blended active medical problems and ongoing specialist relationships. There was also a lengthy Review of Systems under its own heading.

In what would probably have printed out over ten pages long, the final diagnosis was “Urinary tract infection” and the man was prescribed antibiotics.

This final diagnosis seemed to come out of left field. I didn’t recall reading anything about urinary symptoms, urinalysis, an abdominal exam or pain on percussion over the back.

Prior Authorizations: Will They Become Damocles Sword?

In July 2009, the family of Massachusetts teenager Yarushka Rivera went to their local Walgreens to pick up Topomax, an anti-seizure drug that had been keeping her epilepsy in check for years. Rivera had insurance coverage through MassHealth, the state’s Medicaid insurance program for low-income children, and never ran into obstacles obtaining this life-saving medication. But in July of 2009, she turned 19, and when, shortly after her birthday, her family went to pick up the medicine, the pharmacist told them they’d either have to shell out $399.99 to purchase Topomax out-of-pocket or obtain a so-called “prior authorization” in order to have the prescription filled.

Prior authorizations, or PAs as they are often referred to, are bureaucratic hoops that insurance companies require doctors to jump through before pharmacists can fulfill prescriptions for certain drugs. Basically, they boil down to yet another risky cost-cutting measure created by insurance companies, in keeping with their tried-and-true penny-pinching logic: The more hurdles the insurance companies places between patients and their care, the more people who will give up along the way, and the better the insurers’ bottom line.

PAs have been a fixture of our health care system for a while, but the number of drugs that require one seems to be escalating exponentially. Insurance companies claim that PAs are fast and easy. They say pharmacists can electronically forward physicians the necessary paperwork with the click of a mouse, and that doctors shouldn’t need more than 10 minutes to complete the approval process.

The Dunning-Kruger Effect, Or the Real Reason Why the Guys Trying to “Fix” Health Care Are Driving You Crazy

Nov 3, 2017• 2

By HANS DUVEFELT, MD

“The fool doth think he is wise, but the wise man knows himself to be a fool.”
– Willam Shakespeare

I learned about the Dunning-Kruger effect at a medical conference recently. It certainly seems to apply in medicine. So often, a novice thinks he or she has mastered a new skill or achieved full understanding of something complicated, but as time goes on, we all begin to see how little we actually know. Over time, we may regain some or most of our initial confidence, but never all of it. Experience brings at least a measure of humility.

Just the other day I finished a manuscript for an article in a Swedish medical journal with the statement that, 38 years after my medical school graduation, I’m starting to “get warm in my clothes”, as we say in Swedish.

I think the Dunning-Kruger effect applies not only to people who are in the beginning of a career in medicine, but also to people who learn about it for purposes of judging its quality or efficiency or of regulating or managing it from a governmental or administrative point of view.

I think many people outside medicine think “how hard can it be” and then proceed to imagine ways to change how trained medical professionals do their work.

But the Dunning-Kruger effect is also a particular problem in rural primary care. Newly trained physicians, PA’s and Nurse Practitioners are asked to work in relative professional isolation with full responsibility for sizeable patient populations. Unlike the hospital environment, primary care practices seldom have time earmarked for teaching and supervision, and there is little feedback given to such new providers. There is also very seldom collaboration and communication about specific patients or cases. We probably get more feedback from our specialist consultants than we do from the providers in our own clinics, because we are all busy with our own patients.

So, how does a new clinician avoid the newbie hubris Dunning and Kruger describe? Seek out potential mentors and ask them to be yours, start a case conference at your clinic, read the leading journals, NEJM, JAMA, BMJ, The Lancet and ones like them, and read about the history of medicine and the old masters.

From Jeopardy! To Your Physician’s Black Bag: Could a Supercomputer Really Assist With Health Care?

Mar 14, 2011• 6

By DAN PELINO

IBM’s Jeopardy-champion computer, Watson, has huge potential for helping physicians and other clinicians work with patients.

The leap from TV game show to physicians’ offices will probably take at least two years. But Watson’s understanding of natural language, vast storehouse of information and ability to keep up with rapidly changing medical research could significantly improve medical care.

The medical faculty at Columbia University and University of Maryland are helping program a Watson-type computer to assist clinicians.

A few years from now, consulting Watson could become a routine part of a clinician’s practice. Caregivers have traditionally resisted computerized assistance in diagnosis and treatment because the technology has been awkward to use and questionnaire-based systems have been too rigid. But Watson can “understand” descriptions of a patient’s symptoms in natural language, and it can even scan years of medical records and doctors’ notes to determine what diagnostic and therapeutic options it might suggest. Doctors can ask it questions using the same terms they would use in an e-mail to a colleague. Continue reading…

Watson: A Computer So Smart, It Can Say, “Yes, Doctor”

Feb 17, 2011• 3

By MICHAEL MILLENSON

Game Show Watson wants to be a doctor. Well, almost.

Fresh off a commanding victory on Jeopardy, IBM will try to demonstrate that the combination of advanced natural language processing and sophisticated algorithmic decision-making capabilities involved in its extraordinary Watson computer can help humankind, not merely humiliate human competitors.

As I wrote on a previous blog, IBM began eying the medical marketplace more than 45 years ago. IBM CEO Thomas J. Watson, Jr. – son of the IBM CEO for whom this computer was named – put it this way in 1965: “The widespread use [of computers]…in hospitals and physicians’ offices will instantaneously give a doctor or a nurse a patient’s entire medical history, eliminating both guesswork and bad recollection, and sometimes making a difference between life and death.”

Now, IBM is ready to turn that vision into reality. At heart, Watson is the world’s most sophisticated question-answering machine. The company is collaborating with Columbia University and the University of Maryland to create a physician’s assistant service that will allow doctors to query a cybernetic assistant. IBM will also work with Nuance Communications, Inc. to add voice recognition to the physician’s assistant, “possibly making the service available in as little as 18 months.” For Nuance, it could be a major business line, and promises to carry over in the not too distant future to the mobile phone market, such as Apple’s iPhone, where Nuance is a major presence.Continue reading…

Thomas Kuhn, Health Care Reform and Vascular Disease

May 24, 2009• 12

By WILLIAM BESTERMANN

The puzzle of improving care and reducing costs in American medicine and in vascular conditions (that is, diseases associated with blood vessel metabolism) in particular – these are responsible for 60 percent of all cost – has been in part due to the nature of medicine itself. Physicians are at their core scientists. Our undergraduate degrees are in the scientific disciplines of biology, chemistry, physics. We have been educated in the culture of science and that is the environment in which we practice.

Thomas Kuhn’s The Structure of Scientific Revolutions perfectly describes a central problem in cardiovascular diseases. A scientific community cannot practice without a set of core beliefs. These central constructs are, in Kuhn’s terms, the foundation of the “educational initiation that prepares and licenses the student for professional practice.” The student’s instruction is “rigorous and rigid,” with the purpose of ensuring that these beliefs are firmly fixed in the student’s mind.

Scientists go to great lengths to defend the idea that they know what the world is like. It should come as no surprise then that “normal science,” – that is, the framework to explain the world used by the scientists who lead the current paradigm – will often suppress novelties that undermine its foundations.

So research often is not about discovering the unknown, but rather “a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education.” A generally-accepted paradigm, essential to effective scientific investigation, requires “some implicit body of intertwined theoretical and methodological belief that permits selection, evaluation and criticism.” That paradigm, in turn, forms the basis of a new profession or specialty, like Interventional Cardiology, and from this follows the establishment of journals, societies, and a special place in the medical academic structure. The articles in those journals are intended for professional colleagues who share the the field’s knowledge and who are the only ones capable of fully understanding them.

A shift in the accepted scientific construct occurs when research aimed at further developing that formulation of the evidence runs into an anomaly — a fact that does not fit the paradigm and cannot be explained away. When anomalies pop up, they typically are not welcome and may be ignored. The current paradigm’s scientists may make little or no effort to formulate a new theory to explain the phenomenon. They are also likely to be intolerant of practitioners who try to do so.

All the same, the discovery of anomaly is the stimulus that leads to a new paradigm. The failure of existing beliefs and rules is the necessary but insufficient platform for the development of new scientific and practice structure.

The leaders of an entrenched paradigm strongly resist alternate systems of science and practice. Only in crisis can that resistance be overcome. No better example of this can be found than the current situation in the treatment of cardiovascular and arterial disease.

*****

The fixed blockage is the dominant paradigm today for both the science and practice of cardiovascular and arterial disease management. In other words, it is viewed as a plumbing problem. This paradigm has persisted because it made so much sense.

Angina is a historical diagnosis – particularly in a man. Just talk to the patient and you can make the diagnosis. If a man walks and gets chest pain that is relieved by rest, he has angina. Almost all of those men have a blockage of 70% or greater.

If the cardiologist does a catheterization he will demonstrate the blockage. If he opens the blockage with a stent the pain will go away. But many men with angina go on to have heart attacks – it is high risk. So it is no surprise that blockage became the dominant scientific paradigm. To this day, virtually the entirety of the science, practice, and financing are organized around this idea: Heart attacks are caused by a progressive blockage. If we open that blockage before it becomes complete, we will save the patient.

Now the anomaly. In 1988, WC Little and his colleagues at Wake Forest performed a study “to help determine if coronary angiography can predict the site of a future coronary occlusion.” If the plumbing model were correct and a progressive blockage of the artery caused myocardial infarction, the findings on coronary angiography should predict the site of heart attack. It did not.

Little and his colleagues studied 42 consecutive patient records of patients who had had coronary angiography before and up to a month after having a heart attack. In 19 of 29 (66%) patients, the artery that occluded subsequently had less than a 50% occlusion on the first angiogram. In 28 of 29 (97%) the stenosis (or narrowing of the vessel) was less than 70%, even though it takes a stenosis of 70% or greater to justify angioplasty with stenting.

Little concluded

“Because it was difficult to predict the site of subsequent occlusion in our patients from the initial coronary angiogram, coronary bypass surgery or angioplasty appropriately directed only at the angiographically significant lesions initially present in almost all of our patients would not have been effective in preventing the majority of infarctions…instead effective therapy to prevent myocardial infarction may need to be directed at the entire coronary tree…”

And, in keeping with Kuhn’s description of the scientific revolution, the best arterial disease scientists quickly developed a new paradigm that provides a much better explanation of the mechanism of heart attack and other vascular events. Within 7 years of the first anomaly, Erling Falk, Prediman K Shah and Valentin Fuster, leading academic cardiologists, summarized four studies that came to the same conclusion as Little. Only 14% of heart attacks occur in an artery that was 70% blocked on the previous catheterization. Only 14% of heart attacks occurred in an artery with enough obstruction to cause angina and justify bypass surgery or stenting. Falk and his colleagues described the new paradigm very simply:

“plaque disruption with superimposed thrombosis (obstructive clot) is the main cause of the acute coronary syndromes of unstable angina, myocardial infarction, and sudden death.”

Peter Libby is Chief of Cardiology at Boston’s Brigham and Women’s Hospital, one of Harvard’s teaching hospitals. One of the world’s foremost authorities on the science of heart attack and plaque rupture, he quite literally “wrote the book” on the topic. In the volume of Harrison’s Principles of Internal Medicine, the standard reference text for the discipline, that sits on my desk, Peter Libby wrote the chapter entitled The Pathogenesis of Atherosclerosis.

In 1995, the same year as the Falk article, Libby wrote a piece called “The Molecular Basis of the Acute Coronary Syndromes.”

“Bypass surgery or transluminal angioplasty (dilation of the artery and then, propping it open with stents) provide rational and often effective therapies for these fixed, high-grade stenoses (blockages). However, these treatments do not address the non-stenotic but vulnerable plaque (which may rupture and suddenly block the artery with clot). It is of interest in this regard that despite the well-accepted benefit of coronary bypass surgery on anginal symptoms, this treatment aimed at severe stenoses does not prevent myocardial infarction. To reduce the risk of acute myocardial infarction, one must stabilize lesions to prevent this disruptions, particularly the less stenotic plaque.”

In other words, heart attack is not caused by a gradual narrowing of the artery, but rather is the result of sudden cholesterol plaque rupture with subsequent clot formation, which blocks off the artery and cuts off blood flow.

Today, 14 years later, we can dramatically stabilize plaque and reduce plaque progression by smoking cessation and reduction of cholesterol, triglycerides, blood pressure, and blood glucose. We can prevent clot formation with aspirin and other medications.

The scientific revolution in vascular disease is 20 years old and the new paradigm firmly in place and supported by the very best vascular scientists. Still, the practice paradigm persists as if the science never changed.

Just last year, I heard a brilliant talk by Valentin Fuster, one of the co-authors on the Falk article. Afterward I asked him what it would take to move the practice paradigm forward. He responded that it would take the time required to replace current practitioners wi
th the next generation.

Can we afford to wait for that? Several years ago, I heard Dr Libby speak at a national meeting of the American Society of Hypertension. I later asked him, “Dr Libby, I read your article from 1995, saying that bypass and stenting do not prevent heart attack, do you still hold that view.” He became very animated and enthusiastic and said he was convinced that the new science was valid and required action to move it forward.

The science has become irrefutable. Yet the defenders of the old science still carry the day. I fear that medical scientists will not move this forward and it will require changes in payment and support for research coming from outside the professional community to bring the latest science to patients.

We have to recognize the suppression of anomalies and new paradigms in medicine. Only then can we develop mechanisms that can bring the latest evidence-based science to patients.

Medicine’s Missing Foundation for Health Care Reform

Apr 28, 2009• 15

By LAWRENCE L. WEED & LINCOLN WEED

Preface by Michael Millenson: Lawrence L. Weed published a seminal article in the Archives of Internal Medicine on using the medical record to improve patient care back in January, 1971.

To give you an idea of how glacially the health care system changes, that same issue contained an article entitled, “Universal Health Insurance is the Wave of the Future,” by New York Gov. Nelson Rockefeller, and another, “What Possible Use Can Computers Be to Medicine?” by a Duke University physician that began this way: “The physician's attitude toward computing machinery has changed greatly in the last ten years. A bright future is predicted for its application within medicine.”

In an era when the autonomy of the individual physicians was nearly unchallenged, Weed boldly asserted that “modern data acquisition and retrieval systems” could help doctors make more accurate diagnoses and provide “proper care” more effectively. Weed has continued that same fight ever since, later joined by his son, attorney Lincoln Weed. In the process he has acquired neither fame, popularity or riches — merely become legendary to a small segment of us familiar with his work.

ABSTRACT: Medical practice lacks a foundation in scientific behavior corresponding to its foundation in scientific knowledge. The missing foundation involves standards of care to govern how practitioners manage clinical information. These standards of care, roughly analogous to accounting standards for managing financial information, are essential to exploit the enormous potential of health information technology. Moreover, without these standards and corresponding information tools, evidence-based medicine in its current form is unworkable. Medical practice has failed to adopt the necessary standards and tools, because its historical development has diverged from the paths taken in the domains of science and commerce. The culture of medicine tolerates unnecessary dependence on the personal intellects of practitioners. This dependence has blocked the use of potent information tools, and isolated medicine from forces of feedback and accountability, that operate in the domains of science and commerce. If the necessary standards and tools are adopted, health care cost and quality could become an arena of continuous improvement, rather than a quagmire of intractable dilemmas.
