HTTP: Let's GET some REST

From Health Data Management:
HL7 to Accelerate FHIR Specification

With a coalition of providers and health IT vendors, Health Level Seven International has launched a project to accelerate development and adoption of HL7’s Fast Healthcare Interoperability Resources (FHIR).

Called the Argonaut Project, the initiative seeks to rapidly develop a first-generation FHIR-based application programming interface and core data services specification to enable expanded information sharing for electronic health records and other health IT. The goal is to hasten current FHIR development efforts to provide industry with “practical and focused FHIR profiles and implementation guides” by the spring of 2015, according to HL7.

FHIR, which leverages the latest web standards, has been gaining momentum as an open healthcare data standard. In October, the Health IT Standards and Policy Committees’ JASON Task Force recommended that the Office of the National Coordinator for HIT mobilize an accelerated standards development process to ready an initial specification of FHIR for certification to support Meaningful Use Stage 3...

MAN'SPLAININ' RESTful

How I Explained REST to My Wife

Wife: Who is Roy Fielding?
Ryan: Some guy. He's smart.

Wife: Oh? What did he do?
Ryan: He helped write the first web servers and then did a ton of research explaining why the web works the way it does. His name is on the specification for the protocol that is used to get pages from servers to your browser.

Wife: How does it work?
Ryan: The web?

Wife: Yeah.
Ryan: Hmm. Well, it's all pretty amazing really. And the funny thing is that it's all very undervalued. The protocol I was talking about, HTTP, it's capable of all sorts of neat stuff that people ignore for some reason.

Wife: You mean http like the beginning of what I type into the browser?
Ryan: Yeah. That first part tells the browser what protocol to use. That stuff you type in there is one of the most important breakthroughs in the history of computing.

Wife: Why?
Ryan: Because it is capable of describing the location of something anywhere in the worldfrom anywhere in the world. It's the foundation of the web. You can think of it like GPS coordinates for knowledge and information.

Wife: For web pages?
Ryan: For anything really. That guy, Roy Fielding, he talks a lot about what those things point to in that research I was talking about. The web is built on an architectural style called REST. REST provides a definition of a resource, which is what those things point to.

Wife: A web page is a resource?
Ryan: Kind of. A web page is a representation of a resource. Resources are just concepts. URLs--those things that you type into the browser...

Wife: I know what a URL is.
Ryan: Oh, right. Those tell the browser that there's a concept somewhere. A browser can then go ask for a specific representation of the concept. Specifically, the browser asks for the web page representation of the concept.

Wife: What other kinds of representations are there?
Ryan: Actually, representations is one of these things that doesn't get used a lot. In most cases, a resource has only a single representation. But we're hoping that representations will be used more in the future because there's a bunch of new formats popping up all over the place.

Wife: Like what?
Ryan: Hmm. Well, there's this concept that people are calling Web Services. It means a lot of different things to a lot of different people but the basic concept is that machines could use the web just like people do.

Wife: Is this another robot thing?
Ryan: No, not really. I don't mean that machines will be sitting down at the desk and browsing the web. But computers can use those same protocols to send messages back and forth to each other. We've been doing that for a long time but none of the techniques we use today work well when you need to be able to talk to all of the machines in the entire world.

Wife: Why not?
Ryan: Because they weren't designed to be used like that. When Fielding and his buddies started building the web, being able to talk to any machine anywhere in the world was a primary concern. Most of the techniques we use at work to get computers to talk to each other didn't have those requirements. You just needed to talk to a small group of machines.

Wife: And now you need to talk to all the machines?
Ryan: Yes - and more. We need to be able to talk to all machines about all the stuff that's on all the other machines. So we need some way of having one machine tell another machine about a resource that might be on yet another machine.

Wife: What?
Ryan: Let's say you're talking to your sister and she wants to borrow the sweeper or something. But you don't have it - your Mom has it. So you tell your sister to get it from your Mom instead. This happens all the time in real life and it happens all the time when machines start talking too.

Wife: So how do the machines tell each other where things are?
Ryan: The URL, of course. If everything that machines need to talk about has a corresponding URL, you've created the machine equivalent of a noun. That you and I and the rest of the world have agreed on talking about nouns in a certain way is pretty important, eh?

Wife: Yeah.
Ryan: Machines don't have a universal noun - that's why they suck. Every programming language, database, or other kind of system has a different way of talking about nouns. That's why the URL is so important. It let's all of these systems tell each other about each other's nouns.

Wife: But when I'm looking at a web page, I don't think of it like that.
Ryan: Nobody does. Except Fielding and handful of other people. That's why machines still suck.

Wife: What about verbs and pronouns and adjectives?
Ryan: Funny you asked because that's another big aspect of REST. Well, verbs are anyway.

Wife: I was just joking.
Ryan: It was a funny joke but it's actually not a joke at all. Verbs are important. There's a powerful concept in programming and CS theory called polymorphism. That's a geeky way of saying that different nouns can have the same verb applied to them.

Wife: I don't get it.
Ryan: Well.. Look at the coffee table. What are the nouns? Cup, tray, newspaper, remote. Now, what are some things you can do to all of these things?

Wife: I don't get it...
Ryan: You can get them, right? You can pick them up. You can knock them over. You can burn them. You can apply those same exact verbs to any of the objects sitting there.

Wife: Okay... so?
Ryan: Well, that's important. What if instead of me being able to say to you, "get the cup," and "get the newspaper," and "get the remote"; what if instead we needed to come up with different verbs for each of the nouns? I couldn't use the word "get" universally, but instead had to think up a new word for each verb/noun combination.

Wife: Wow! That's weird.
Ryan: Yes, it is. Our brains are somehow smart enough to know that the same verbs can be applied to many different nouns. Some verbs are more specific than others and apply only to a small set of nouns. For instance, I can't drive a cup and I can't drink a car. But some verbs are almost universal like GET, PUT, and DELETE.

Wife: You can't DELETE a cup.
Ryan: Well, okay, but you can throw it away. That was another joke, right?

Wife: Yeah.
Ryan: So anyway, HTTP--this protocol Fielding and his friends created--is all about applying verbs to nouns. For instance, when you go to a web page, the browser does an HTTP GET on the URL you type in and back comes a web page.

Web pages usually have images, right? Those are separate resources. The web page just specifies the URLs to the images and the browser goes and does more HTTP GETs on them until all the resources are obtained and the web page is displayed. But the important thing here is that very different kinds of nouns can be treated the same. Whether the noun is an image, text, video, an mp3, a slideshow, whatever. I can GET all of those things the same way given a URL.

Wife: Sounds like GET is a pretty important verb.
Ryan: It is. Especially when you're using a web browser because browsers pretty much justGET stuff. They don't do a lot of other types of interaction with resources. This is a problem because it has led many people to assume that HTTP is just for GETing. But HTTP is actually ageneral purpose protocol for applying verbs to nouns.

Wife: Cool. But I still don't see how this changes anything. What kinds of nouns and verbs do you want?
Ryan: Well the nouns are there but not in the right format.

Think about when you're browsing around amazon.com looking for things to buy me for Christmas. Imagine each of the products as being nouns. Now, if they were available in a representation that a machine could understand, you could do a lot of neat things.

Wife: Why can't a machine understand a normal web page?
Ryan: Because web pages are designed to be understood by people. A machine doesn't care about layout and styling. Machines basically just need the data. Ideally, every URL would have a human readable and a machine readable representation. When a machine GETs the resource, it will ask for the machine readable one. When a browser GETs a resource for a human, it will ask for the human readable one.

Wife: So people would have to make machine formats for all their pages?
Ryan: If it were valuable.

Look, we've been talking about this with a lot of abstraction. How about we take a real example. You're a teacher - at school I bet you have a big computer system, or three or four computer systems more likely, that let you manage students: what classes they're in, what grades they're getting, emergency contacts, information about the books you teach out of, etc. If the systems are web-based, then there's probably a URL for each of the nouns involved here: student, teacher, class, book, room, etc. Right now, getting the URL through the browser gives you a web page. If there were a machine readable representation for each URL, then it would be trivial to latch new tools onto the system because all of that information would be consumable in a standard way. It would also make it quite a bit easier for each of the systems to talk to each  other. Or, you could build a state or country-wide system that was able to talk to each of the individual school systems to collect testing scores. The possibilities are endless.

Each of the systems would get information from each other using a simple HTTP GET. If one system needs to add something to another system, it would use an HTTP POST. If a system wants to update something in another system, it uses an HTTP PUT. The only thing left to figure out is what the data should look like.

Wife: So this is what you and all the computer people are working on now? Deciding what the data should look like?
Ryan: Sadly, no. Instead, the large majority are busy writing layers of complex specifications for doing this stuff in a different way that isn't nearly as useful or eloquent. Nouns aren't universal and verbs aren't polymorphic. We're throwing out decades of real field usage and proven technique and starting over with something that looks a lot like other systems that have failed in the past. We're using HTTP but only because it helps us talk to our network and security people less. We're trading simplicity for flashy tools and wizards.

Wife: Why?
Ryan: I have no idea.

Wife: Why don't you say something?
Ryan: Maybe I will.

We welcome Mad*Pow to the Peoples' Republic


I've encountered some of these folks at the many Health IT conferences I've attended throughout the past few years. Nice people, all very bright. They're heavy into UX, a sorely needed area of improvement in the health care space.
Whether we are helping insurers deliver better service to their members, creating experiences to guide patients through their navigation of the system, designing platforms for clinicians to collaborate around care and treatment, or partnering with  a cutting-edge healthcare technology company to bring their vision to life, we have a mission. Deliver real meaning, value, impact and outcomes through the experiences we create.

We understand the healthcare space, the entire space. Not just one facet, but the intricate and complex spectrum that encompasses government agencies, non-profits, insurance companies, hospitals, pharmacies, patients, caregivers, and doctors. We have designed groundbreaking solutions for each area and need present in this ecosystem and it is this experience that gives us the unique ability to see opportunities for engagement and improvement where others only see obstacles.

Our methods are routed in research, grounded in a collaborative approach, and guided by the true empathy we have developed through thousands of interviews with the real humans who sit at the center of this network...
We're now BART neighbors. Glad to see them expanding into California with full time boots on the ground. I wish them the best.

Been studying things related to Dr. Jerome Carter's latest EHR Science post "A Place for Everything Clinical Workflow…" Petri nets, 'eh? (pdf)

Not sure how much traction that is gonna get at the clinic level. There will have to be heavy and continuous clinical end-user understanding and collaboration.

MEANINGFUL USE CALENDAR YEAR 2014 CLOSES IN TWO WEEKS

257K Meaningful Use EPs to Get Medicare Payment Adjustments
Kyle Murphy, PhD | Date December 17, 2014

Over the next few weeks, more than 257,000 provider eligible for the Medicare EHR Incentive Program will receive notice that they will be subject to Medicare payment adjustments beginning in 2015.

Earlier today, the Centers for Medicare & Medicaid Services (CMS) revealed the number of eligible professionals who would reductions in their Medicare payments in 2015 for failing to demonstrate meaningful use in previous years...
MEANINGFUL USE PENALTIES STIR PHYSICAN LOBBY: 

Physician groups seem to think the latest bad news from CMS may improve their chances of getting changes in the meaningful use program. Roughly half of the eligible providers — 257,000 physicians, dentists, chiropractors, optometrists and podiatrists will have their Medicare payments cut by 1 percent starting next month. CMS said yesterday that it will start alerting providers next week of the penalties. The news could add pressure on the administration to adjust the meaningful use program. While the 257,000 are being penalized for failing to reach Stage 1 of the meaningful use program, Stage 2 seems to be an even steeper climb — only 4 percent of all eligible providers had attested to it by Dec. 1; they have until April to reach the goal but are required to attest for a full year in 2015 or face penalties. The American Medical Association said it was “appalled” by the news. It called for CMS to overhaul the program and align it with the “regulatory tsunami” of other requirements doctors face.

SPEAKING OF HEALTH IT LEGISLATION
EHRA Opposes Effort to Decertify EHRs Blocking Information Sharing

The Electronic Health Record Association does not support Congress’ call for the decertification of EHR products that block the sharing of health information, a provision included in the fiscal year 2015 omnibus appropriations bill.

While the association supports efforts to reduce barriers to interoperability, such as the roadmap being developed by the Office of the National Coordinator for HIT to advance the use of interoperable health information, EHRA chair Mark Segal tells Health Data Management that the organization believes congressionally-mandated product decertification would have negative effects on the healthcare industry as a whole.

“We do not believe that the concept of decertifying products that met and continue to meet federal interoperability certification criteria, which align with meaningful use requirements, would be an effective solution to the challenges faced by providers tasked with exchanging data,” argues Segal, who is also vice president of government and industry affairs for GE Healthcare IT. “In fact, we believe it would introduce costly uncertainty into the industry and prevent clients using such products from attesting for meaningful use or employing them in other important delivery reform initiatives.”

The FY15 spending bill, which President Obama signed into law on Tuesday, calls on ONC to “take steps to decertify products that proactively block the sharing of information because those practices frustrate congressional intent, devalue taxpayer investments in [Certified EHR Technology], and make CEHRT less valuable and more burdensome for eligible hospitals and eligible providers to use.”...
Only one problem. There's no such language in the final bill that passed both houses. The language is contained in a pre-passage markup "bill report" (pdf). There's nothing in the law pertaining to this, so everybody chill out.

Someone in Congress may have indeed have been "calling for" it, but the only binding elements are those actually in the law.

UPDATE

Just bought another book pertaining to the so-called "Art of Medicine" (topic of my prior post). Looks interesting. Stay tuned.

FORWARD

THE RELATIONSHIP BETWEEN A PHYSICIAN and patient is truly multidimensional. Dr. Herbert Ho Ping Kong captures this important concept in the opening chapter of The Art of Medicine when he emphasizes the art of seeing, listening, human touch, empathy, advocacy, recognizing suffering and thinking outside the box. Then, in his remarkable style of clinical narrative, Dr. Ho Ping Kong proceeds to interweave patients’ stories with proverb, literary quotation and metaphor to illustrate the relevance of these arts as essential to effective medical practice...

A PERSONAL NOTE

My wife and I are off to College Park, Maryland early Friday for our son's graduation from UM with a degree in Operations Management. He's acquitted himself with distinction, all while working at Reagan as a ramp rat with JetBlue. Proud Papa. I'm equally happy that my daughter has just been named Executive Director of the Bay Area Stepping Stones Project.

“The art of medicine consists of amusing the patient while nature cures the disease”


The post title quote above is attributed to Voltaire, 1778. I pick up where I left off  in my December 7th prior post "#Data4Health San Francisco listening session." I repeat:
Where do "data" ("do," not "does") fit into concepts such as the (controversial phrase) "art of medicine"? Are we subtly yet significantly more than the sum of our "structured data"?
John Haughom, MD, writes at THCB:
Physicians have always been in the information business. We have kept records of patient data regarding the vital signs, allergies, illnesses, injuries, medications, and treatments for the patients we serve. We seek knowledge from other physicians, whether that knowledge comes from the conclusions of experts from research published in a medical journal or the specialist down the hall. However, a physician will always benefit from additional good information such as the analysis of pooled data from our peers treating similar patients or from the patients themselves.

Over the next few years, vast new pools of data regarding the physiologic status, behaviors, environment, and genomes of patients will create amazing new possibilities for both patients and care providers. Data will change our understanding of health and disease and provide a rich new resource to improve clinical care and maximize patient health and well-being...
So, yeah, apropos of #Data4Health, etc, we're increasingly to be ever-more conveniently and inexpensively awash in all manner of health-related "data," "big" and small, coursing from far-flung watersheds comprised of "upstream" and "omics" tributaries, emanating from mobile devices, captured by and reposed in EHRs and PHRs and "the Cloud," nearly all of these data compactly "structured" -- numbers and alphanumeric codes ("lossy compression?") --  ever-more readily ("interoperably?") acquired, transcribed, viewed, edited, transmitted, appended, merged, synthesized, and evaluated for improved dx and px/tx.

So goes the theory.


"Lossy Compression?" Think of .jpeg images and .mp3 audio files, both of which have algorithmically removed (via "proximity redundancy" elimination) up to 90% of the raw binary data from source files while still yielding acceptable viewing and listening output for most ambient viewing/listening environments. It's call "lossy" because once the original bits are discarded, they are gone for good. The compression process is irreversible.

Reducing the clinical encounter to "structured data" comprised of numbers and informatics codes is essentially that -- "lossy compression." But, what gets lost? The narrative nuance originating in the open-ended textual "subjective" component of the SOAP (both as self-reported by the patient and the clinicians' subsequent "impressions")? Do such narrative "data" go to the root of "The Art of Medicine"? In the era of productivity treadmill "Fast Medicine," are such losses inevitable -- and negligible?

I have long been conflicted over the phrase "art of medicine." Is it a dodge proffered as a disavowal of responsibility in the wake adverse outcomes (particularly in light of the relatively loose coupling of cause and effect in clinical science)? Is it legitimately invoked in pushback over what clinicians decry as top-down mandated EBM / "cookbook medicine"? Are the imaginative ("creative?") heuristic leaps of the adroit physician an inescapably necessary and net value-adding component of the diagnostic and healing method? Is that what we mean by "The Art of Medicine?"

On the tx side of things, matters can be a bit more straightforward. One surgeon may have a rep and a record of being a hack and a butcher while another performs sensitive and precise work that can only be described as "exquisite," "artful."

Diagnostics are inescapably far murkier. Symptoms map overlappingly to myriad disorders, and the lexical narrative fluency of patients to describe them and clinicians to subsequently interpret them varies widely.

Get it right and you're a hero. Get it wrong and you may have a MedMal problem. In a world of reduced reimbursements, the relentless creep of encroaching daily time constraints, and ever-more complex technology and medical research findings (not to mention increasingly onerous regulations), simply navigating the numeric digits and the alphanumeric codes easily fills the clinicians' days.

Clay Jones, writing at Science Based Medicine: "Is There a Role for the Art of Medicine in Science-Based Practice?"
Over the decades, as evidence has accumulated, we have learned a vast array of patterns and associations that are beyond the ability of most if not all individual physicians to maintain a complete working knowledge of. Hence we must increasingly rely on specialists who focus on specific areas of medicine and, when possible, the incorporation of the available evidence into algorithms that fit most patients most of the time. It is hard to deny the improved accuracy and outcomes that this approach has led to.

Certainly there will always be exceptions where patients don’t present in such a way that an applicable protocol is easily chosen or even available, and diagnosis does elude us at times. And patients will not always respond to treatment as we expect them to. But we must be wary of experience-based practice that focuses too much on individualization. Without due caution, and awareness of the many biases and errors in perception that plague us all, the difference between expert-level subconscious pattern recognition and the bogus concept of medical intuition may not always be clear...


In my opinion, the phrase “art of medicine” needs to be retired or at least restricted in use. Aside from being nebulous to the point of nearly losing all meaning, and serving as fertile ground for all manner of bogus approaches to healthcare, to me it almost implies that there should be some kind of innate ability to practice medicine that some people have and some don’t. I don’t believe that there are medical equivalents of Leonardo da Vinci or Yo Yo Ma, virtuosos with skill that can’t be acquired by practice alone.

But we shouldn’t throw the baby out with the bathwater. While I certainly understand the desire to have an all-encompassing ideal phrase, I believe that we would be better served to be more specific when talking about the important aspects of being an effective healthcare professional, and more honest about when we are making an educated guess secondary to a lack of evidence. When a legitimate healthcare professional chalks their action up to the art of medicine, it lends credence to when a quack does the same thing...
Yeah. But, in addition to myriad other concerns, what of cultural considerations? Is the western reductive science paradigm the sine qua non of clinical cognition? Or, does that smack of "scientism"?

I return to a citation I made on another of my blogs years ago.

On the bulletin board in the front hall of the hospital where I work, there appeared an announcement. “Yeshi Dhonden,” it read, “will make rounds at six o’clock on the morning of June 10.” The particulars were then given, followed by a notation: “Yeshi Dhonden is personal physician to the Dalai Lama.” I am not so leathery a skeptic that I would knowingly ignore an emissary from the gods. Not only might such sangfroid be inimical to one’s earthly well-being, it could take care of eternity as well. Thus, on the morning of June 10, I joined a clutch of whitecoats waiting in the small conference room adjacent to the ward selected for the rounds. The air in the room is heavy with ill concealed dubiety and suspicion of bamboozlement. At precisely 6 o’clock, he materializes, a short, golden, barrely man dressed in a sleeveless robe of saffron and maroon. His scalp is shaven, and the only visible hair is a scanty black line each hooded eye.

He bows in greeting while his young interpreter makes the introduction. Yeshi Dhonden, we are told will examine a patient selected by a member of the staff. The diagnosis is as unknown to Yeshi Dhonden as it is to us. The examination of the patient will take place in our presence, after which we will reconvene in the conference room where Yeshi Dhonden will discuss the case. We are further informed that for the past two hours Yeshi Dhonden has purified himself by bathing, fasting, and prayer. I, having breakfasted well, performed only the most desultory of ablutions, and given no thought at all to my soul, glanced furtively at my fellows. Suddenly, we seem a soiled, uncouth lot.


The patient had been awakened early and told that she was to be examined by a foreign doctor, and had been asked to produce a fresh specimen of urine, so when we enter her room, the woman shows no surprise. She has long ago taken on that mixture of compliance and resignation that is that the facies of chronic illness. This was to be but another in an endless series of tests and examinations. Yeshi Dhonden steps to the bedside while the rest stand apart, watching. For a long time he gazes at the woman, favoring no part of her body with his eyes, but seeming to fix his glance at a place just above her supine form. I, too, study her. No physical sign nor obvious symptom gives a clue to the nature of her disease.


At last he takes her hand, raising it in both of his own. Now he bends over the bed in a kind of crouching stance, his head drawn down into the collar of his robe. His eyes are closed as he feels for her pulse. In a moment he has found the spot, and for the next half hour he remains of us, suspended above the patient like some exotic golden bird with folded wings, holding the pulse of the woman beneath his fingers, cradling her hand in his. All the power of the man seems to have been drawn down into this one purpose. It is tell patient of the pulse raced to the state of ritual. From the foot of the bed, where I stand, it is as though he and the patient had entered a special place of isolation, of apartness, about which a vacancy hovers, and across which no violation is possible. After a moment the woman rests back upon her pillow. From time to time she raises her head to look at the strange figure above her, then sinks back once more. I cannot see their hands joined in a correspondence that is exclusive, intimate, his fingertips receiving the voice of her sick body through the rhythm and throb she offers at her wrist. All at once I am envious -- not of him, not of Yeshi Dhonden for his gift of beauty in holiness, but of her. I want to be held like that, touched so, received. And I know that I, who have palpated 100,000 pulses, have not felt a single one.


At last Yeshi Dhonden straightens, gently places the woman’s hand upon the bed, and steps back. The interpreter produces a small wooden bowl into sticks. Yeshi Dhonden pours a portion of the urine specimen into the bowl, and proceeds to whip the liquid with the two sticks. This he does for several minutes until a foam is raised. Then, bowing above the bowl, he inhales the older three times. He sets down the bowl, and turns to leave. All this while, he has not uttered a single word. As he nears the door, the woman raises her head and calls out to him in a voice at once urgent and serene. “Thank you, doctor,” she says, and touches with her other hand the place he had held on her wrists, as though to recapture something that had visited their. Yeshi Dhonden turns back for a moment to gaze at her, then steps into the corridor. Rounds are at an end.


We are seated once more in the conference room. Yeshi Dhonden speaks now for the first time, in soft Tibetan sounds that I’ve never heard before. He has barely begun when the young interpreter begins to translate, the two voices continuing in tandem – a bilingual fugue, the one chasing the other. It is like the chanting of monks. He speaks of winds coursing through the body of the woman, currents that break against barriers, eddying. These vortices are in her blood, he says. The last spendings of an imperfect heart. Between the chambers of her heart, long, long before she was born, a wind had come and blown open a deep gate that must never be opened. Through it charged the full waters of her river, as the mountain stream cascades in the springtime, battering, knocking loose the land, and flooding her breath. Thus he speaks, and is silent.


“May we now have the diagnosis?” A professor asks.


The host of these rounds, the man who knows, answers. “Congenital heart disease,” he says. “Interventricular septal defect, with resultant heart failure.”


A gateway in the heart, I think. That must not be opened. Through it charge the full waters that flood her breath. So! Here then is the doctor listening to the sounds of the body to which the rest of us are deaf. He is more than doctor. He is Priest.


I know, I know, the doctor to the gods is pure knowledge you’re healing. The doctor to man stumbles, most often wound; his patient must die, as must he.


Now and then it happens, as I make my own rounds, but I hear the sounds of his voice, like an ancient Buddhist prayer, its meaning long since forgotten, only the music remaining.


Then the jubilation possesses me, and I feel myself touched by something divine.
[1976: Richard Selzer, MD, Mortal Lessons: Notes on the art of surgery]
I have had Dr. Selzer's books for decades. He is truly an "artist" in the literary sense. And, his works are now available in e-book formats.
LESSONS FROM THE ART

A man of letters lies in the intensive care unit. A professor, used to words and students. He has corrected the sentences of many. He understands punctuation. One day in his classroom he was speaking of Emily Dickinson when suddenly he grew pale, and a wonder sprang upon his face, as though he had just, for the first time, seen something, understood something that had eluded him all his life. It was the look of the Wound, the struck blow that makes no noise, but happens in the depths somewhere, unseen. His students could not have known that at that moment his stomach had perforated, that even as he spoke, its contents were issuing forth into his peritoneal cavity like a horde of marauding goblins. From the blackboard to the desk he reeled, fell across the top of it, and turning his face to one side, he vomited up his blood, great gouts and gobbets of it, as though having given his class the last of his spirit, he now offered them his fluid and cells.

In time, he was carried to the operating room, this man whom I had known, who had taught me poetry. I took him up, in my hands, and laid him open, and found from where he bled. I stitched it up, and bandaged him, and said later, “Now you are whole.”

But it was not so, for he had begun to die. And I could not keep him from it, not with all my earnestness, so sure was his course. From surgery he was taken to the intensive care unit. His family, his students were stopped at the electronic door. They could not pass, for he had entered a new state of being, a strange antechamber where they may not go.

For three weeks he has dwelt in that House of Intensive Care, punctured by needles, wearing tubes of many calibers in all of his orifices, irrigated, dialyzed, insufflated, pumped, and drained ... and feeling every prick and pressure the way a lover feels desire spring acutely to his skin.

In the room a woman moves. She is dressed in white. Lovingly she measures his hourly flow of urine . With hands familiar, she delivers oxygen to his nostrils and counts his pulse as though she were telling beads. Each bit of his decline she records with her heart full of grief, shaking her head. At last, she turns from her machinery to the simple touch of the flesh. Sighing, she strips back the sheet, and bathes his limbs.

The man of letters did not know this woman before. Preoccupied with dying, he is scarcely aware of her presence now. But this nurse is his wife in his new life of dying. They are close, these two, intimate, depending one upon the other, loving. It is a marriage, for although they own no shared past, they possess this awful, intense present, this matrimonial now, that binds them as strongly as any promise.

 A man does not know whose hands will stroke from him the last bubbles of his life. That alone should make him kinder to strangers…

 Far away from the operating room, the surgeon is taught that some deaths are undeniable, that this does not deny their meaning. To perceive tragedy is to wring from it beauty and truth. It is a thing beyond mere competence and technique, or the handsomeness to precisely cut and stitch. Further , he learns that love can bloom in the stoniest desert, an intensive care unit, perhaps.

These are things of longest memory, and like memory, they cut.

When the patient becomes the surgeon, he goes straight for the soul.

I do not know when it was that I understood that it is precisely this hell in which we wage our lives that offers us the energy , the possibility to care for each other. A surgeon does not slip from his mother’s womb with compassion smeared upon him like the drippings of his birth. It is much later that it comes. No easy shaft of grace this, but the cumulative murmuring of the numberless wounds he has dressed, the incisions he has made, all the sores and ulcers and cavities he has touched in order to heal. In the beginning it is barely audible, a whisper, as from many mouths. Slowly it gathers, rises from the streaming flesh until, at last, it is a pure calling—an exclusive sound, like the cry of certain solitary birds— telling that out of the resonance between the sick man and the one who tends him there may spring that profound courtesy that the religious call Love

Indeed. One literate physician, this man. More Selzer here, on another of my blogs.

Below, another of my favs, apropos of non-productivity treadmill "Slow Medicine."

When my family learned I was going to medical school, they were shocked. No one in the family— and our family history goes way back— had ever been a doctor, medicine being too physical a profession for our businessmen and intellectuals. Medicine was too physical for me also, but it intrigued me with its possibility of engaging with what Catholics call the last things: death, resurrection, heaven, hell, and purgatory. Also , I liked that medicine would require me to meet with everyone on a kind of equal basis. Anyhow, I reassured them, I was going into medicine through a side door that was not physical at all— the door of psychiatry. The work of Carl Jung fascinated me, and I hoped to imitate his life— seeing brilliant, well-paying patients in the morning in my stone house on Lake Zurich, writing and lecturing in the afternoon.

After the first two years of medical school, which teach the basics of medicine— anatomy, physiology, biochemistry, and pharmacology— there are the two clinical years, when the student gets to apply this learning to real patients. I hadn’t expected to like this part, but I did. There was a lot of psychology to it. I discovered that I loved taking the “history”— the story that the patient tells, within which is hidden the real meaning of his condition. I loved the physical examination of the patient, on whose body was written, if I could only read it, the real diagnosis . And I loved analyzing the facts and reaching a conclusion, which is the diagnosis, the treatment, and the plan.

After medical school I started my psychiatric training. But psychiatry, I soon realized, had changed since Jung. Madness was now located in the brain and caused by a chemical imbalance; its treatment was not analysis but medication, which often worked remarkably well. So instead of becoming a psychiatrist, I went out and practiced medicine in a county clinic, and then in a rural private practice. Eventually I went back for more training and finished the three years of a medical residency. After that I practiced in a community clinic and became its medical director.

During all those years I was ever more impressed by the power of modern medicine— by its logic, its method for arriving at a diagnosis and a treatment. Yet every now and again I had other experiences like that with Mr. Baker— experiences that left me wondering. The moment of birth. The moment of death. A mysterious knowing of just when a patient was about to get ill. All evidence of some subtle but shared world, where beings popped up and disappeared, of invisible connections with visible effects.

Naturally, I assumed that modern medicine had investigated such phenomena, and I began to research what it had learned about them. They had acquired very boring names, I immediately discovered: the “doctor-patient relationship”; the “placebo effect”; “psychosomatism”; the “effect of prayer.” Also, they had been assigned to the realm of psychology, where they had been psychologized— separated, that is, from the body where I’d seen and felt them.

Next, I looked at alternative medicine for answers. Chinese and Indian medicine did give me some insights, since the body they described was a body of flows and blockages, balances and imbalances, a body that might explain the borderless energy I’d felt in my patients . But the languages and cultures of Chinese and Indian medicine were just too different; they stood in the way of my integrating their point of view into my own.

It was at this discouraging moment that I stumbled across a book that surprised me. It was the record of a German nun’s medical practice from the Middle Ages, translated from the Latin. Hildegard of Bingen, I learned in its introduction, had been a twelfth-century German mystic, theologian, and, amazingly, medical practitioner, and she had written a book about her medicine. And, although Hildegard of Bingen’s Medicine was not a great book, it was thrilling. Because the world underlying its medicine was just the kind of world in which the observations I had tucked away for so many years had been known and used— in the West.

So I began to study Hildegard’s medicine. I began to realize that our medicine, modern medicine, had not been the first Western system for explaining the body, but the second. Before the reductive modern medicine I’d learned in medical school, there had been a different medical system in the West. This “premodern medicine” had originated with Hippocrates in the fifth century BC, and it had once been how everyone understood the body. Its approach, I realized as I studied Hildegard’s medicine, was not mechanistic: The body was not imagined as a machine nor disease as a mechanical breakdown.

But if the body was not imagined as a machine, I wondered, then how had it been imagined in the 2,500 years that preceded my medical education? Could it be that the West did have explanations for the difference between the dead body and the living, and for the other experiences I’d had in my medical life? And that these explanations had been thrown out with the triumphs of modern medicine ? Did premodern medicine and modern medicine perhaps make up a unit— one thing seen from two perspectives, like those drawings that show two different images at the same time?

I didn’t know. But I was intrigued, and I resolved to find out.

To do so, I needed time, however, and time was another concept left out of modern medicine. In the premodern world , medicine had not been a full-time profession but a craft, transmitted through families and learned as an apprentice. Most practitioners, therefore, were not only doctors, but doctors and something else. The elite were doctors and professors; the majority were doctors and farmers, doctors and herbalists, doctors and barbers. This had some advantages. For the patient, it meant that doctors had more than one point of reference; for the doctor, he or she had time to think about other things in other ways.

In the modern world, though, medical training was arduous and costly; physicians were obliged, both professionally and financially, to be available to their patients at every hour of the day and night. Personal time was scarce, and part-time positions unheard of. Today this is no longer the case. Medicine has completed its metamorphosis from craft to profession to commodity, and health-care providers now sell their wares— that is, their time— by the piece on the open marketplace.

Dr. Dan was not the first doctor at Laguna Honda to take care of Janice Gilroy.

At fifty, Ms. Gilroy had come and gone and come back to us many times. She was of the rare breed of Bad Girl and had been saved by modern medicine from the worst consequence of her badness— namely death— but preserved for quite a bit of suffering, as she resided just this side of death. Laguna Honda had always had a few patients like her, but now it had many more, as medicine became more and more amazing, bringing patients back— but just a little back— from the brink.

Ms. Gilroy was a drug abuser, and she would use anything, especially cocaine, marijuana, heroin, and alcohol. Cocaine is especially hard on the body, and Ms. Gilroy had the high blood pressure, kidney disease, and poor circulation to show for it. She had the poor memory of the chronic marijuana user, the bad liver of the heroin user, and the weak heart of the alcoholic. This was in general.

But in particular, she’d had a stroke in the right side of her brain. Now, a stroke on the right side of the brain is both easier and harder than a stroke on the left side of the brain. It is easier because a stroke on the right side of the brain does not injure the left side of the brain, with its capacity for speech. Also, because the brain is cross-wired, a stroke on the right side of the brain does not paralyze the right side of the body, with its usually more dexterous abilities, but the left side, and so is usually less disabling.

But a stroke on the right side of the brain is harder than one on the left because the right side of the brain has something special about it, indefinable and unnamed— a kind of centered cheerfulness— and with a stroke on the right side of the brain, a patient often becomes depressed. So that in addition to being paralyzed on her left side, and in addition to her other disabilities, Ms. Gilroy was also despondent. As an antidote to her depression , she used drugs whenever she could get them, which would upset the delicate balance among her many medications and diseases, and put her right back in the hospital.

When she wasn’t in the hospital, she lived with her daughter, who did not quite understand her mother’s disabilities nor the imperative of keeping her away from drugs. So Ms. Gilroy would stabilize at Laguna Honda, and then her daughter would take her home on a pass or even against medical advice, where she would eat, drink, and be merry, and end up back in the intensive care unit and then back with us. I’d admitted her myself in the past.

But this time it was Dr. Dan who admitted her, and he’d done a good job. He had told her daughter off—there’s no other way to say it— and she’d made herself scarce. Hence, Ms. Gilroy had no access to drugs; she wasn’t eating food that threw her system off; nor was she being taken home clandestinely, though with the best intentions in the world. And she’d improved. Everything about her was just a little bit better— heart, liver, kidneys. Until this afternoon, Dr. Dan told me, when she’d deteriorated. Actually, it had started three days earlier. At morning nursing rounds he’d heard that Ms. Gilroy was different somehow— moaning, confused, and complaining of pain. So he’d ordered pain medications. But the next day she was worse— agitated and still complaining of pain. So he’d ordered more pain medications and added something for restlessness.

Did he examine her? I asked him.

Not exactly. But he had checked her blood and urine and didn’t find any infection or illicit drugs. Then he asked the psychiatrist to see her, because perhaps the change in her mental status was psychiatric. The psychiatrist did see her and he increased her antipsychotic medications, but still she was no better . She was worse— more restless, agitated, and confused. Dr. Dan had a meeting to attend; would I take a look and try to figure out what was wrong with her?

Wow.

Trying to find the cause for the change in mental status that Dr. Dan described was daunting. Especially in someone as ill as Ms. Gilroy. There were endless possibilities. She would need a brain scan and a bone scan, a spinal tap, perhaps biopsies, and even after those, the complexity of her medical problems would doubtless require another prolonged hospitalization at the country . But Ms. Gilroy came after Steve Harp. So instead of first going through her records, talking to her family and the nurses, and then examining her, I went over to see her for myself. I’d learned from Steve that seeing the real patient was worth a thousand words.

The nurses had moved Ms. Gilroy from the open ward into one of the private rooms, I learned, which meant she must have been very agitated. When I came into her room I saw that they had also turned off the lights, pulled down the shades, and set up a large fan, blowing full blast. Although it was quiet, dark, and cool in the room, Ms. Gilroy, nevertheless, was lying on top of the sheets, stark naked. She was restless, tossing and turning and picking at the sheets, and sweat was beading off her body. When I tried to talk to her, she kept her eyes tightly shut and didn’t answer my questions, and when I tried to examine her, she screamed. I couldn’t examine her, not with my usual questions and answers, stethoscope and reflex hammer. It made me wonder how the nurses could have been getting her blood pressure, pulse, and temperature.

After Mrs. Han, Mr. Conley was a little looser about sitters, and Ms. Gilroy did have a sitter, who was reading a magazine in a chair at the foot of the bed. But I wanted to sit myself. So I asked her to go out on break, and after she left, I pulled the chair right next to Ms. Gilroy and sat down.

I sat for quite a while.

The hospital was often hot but with the shades down, the lights off, and a fan on, it was cool in the room. At first. Yet as I sat there and the minutes passed, and I watched Ms. Gilroy toss and turn, shake her head from side to side, and throw off anything that touched her naked body, I, too, began to feel hot and restless. I began to feel as if I wanted to crawl out of my skin; as if there were something in my body— some toxin, some poison—that just had to get out. And at that moment, I realized that Ms. Gilroy was acting as if she’d been poisoned , as if there were a toxin in her body that had to get out.

I wondered. Could she have been poisoned?

An actual poisoning didn’t seem likely. Despite its checkered history, Laguna Honda had never yet had a poisoner. If Ms. Gilroy was being poisoned, it was by something internal: an obscure infection, a hallucinogen she’d gotten hold of, or, most likely, by some medication she was taking.

So I left the room to get her chart; it was time to take a look. I brought it back, sat down again, and began to review what she’d been prescribed.

Dr. Dan had not added any new medications to her regime; all he’d done was increase the ones she’d already been getting— the pain medications, sedatives, antipsychotics, and antidepressants. Nevertheless, Ms. Gilroy was being poisoned, I was more and more certain, and by something that made her hot, restless, agitated, and confused.

Suddenly it occurred to me.

Serotonin syndrome.

I’d never seen it, but I’d read about it. Serotonin is a natural chemical made by the brain, and each one of Ms. Gilroy’s medications increased it. Taken all together and in escalating doses, they could have raised her brain serotonin to a toxic level, which would provoke the symptoms she had— agitation, confusion, hyperthermia . I sat and thought about it, while Ms. Gilroy moaned and picked at nonexistent bedclothes.

My problem was that there was no test for serotonin syndrome— no blood test or X-ray. The only way I could diagnose it would be to take her off her medications, and this could be dangerous, because if she did have something else instead of serotonin syndrome— an unusual kind of stroke, for instance, or an infection, or something I hadn’t thought of— taking her off her medications would make her more, not less, agitated, and make her worse. But if she did have serotonin syndrome , then I had to stop her medications immediately because serotonin syndrome is fatal.

I was sure enough, and after I explained my thinking to Dr. Dan, he agreed. I decreased Ms. Gilroy’s sedatives, antipsychotics, antidepressants, and pain medications just a little; within a few hours, she’d improved. I took her off all of them, and she calmed and cleared. Eventually she even went home again to her daughter, for a while.

Like so many of my experiences at Laguna Honda, that sitting with Ms. Gilroy in her dark and cool room as she tossed and turned changed me and stayed with me. I thought about it a lot. I’d done so little for her, even less than I’d done for Steve. I hadn’t looked into her eyes, held her hand, or reviewed all her records. I’d done nothing at all. Except sit. But how effective that had been! The diagnosis had appeared without me sending her to the emergency room, without additional tests, scans, or biopsies. Somehow, just by sitting with her, I’d understood what was wrong.

I began to try it with my other patients. Just sitting.

Just sitting was not the same thing as sitting, however. It’s a little hard to explain. It was sitting, but it was not sitting and doing something— reading or talking— and it wasn’t the “just sitting” of Zen either, which is a strenuous, focused vacancy. It was, I decided, like the mental state of knitting, but it was most like waiting for a train in Switzerland. I remembered that well. Sitting on a bench, with ticket purchased and in your pocket, knowing that the train will arrive on time; there is nothing more to worry about and nothing more to do. The activity of the train station flows around you, and you observe, but not intently; you are aware, but not focused. People come and go; there is a hustle and bustle; but it is not your hustle and bustle.

That was “just sitting,” and after Ms. Gilroy, I took the time to “just sit” in this way with all my patients. Especially if they took a turn for the worse, or if a nurse or a family member was worried that something wasn’t quite right. I would leave my cell phone in the nursing station, turn off my beeper, move a chair next to the patient, and sit down. Not for long— five or ten minutes . Sometimes the patient would want to chat, and we would chat, and sometimes I would study the patient’s face, bedclothes, and bureau. But mostly I would just sit. And something, somehow, would happen. It would become clear what, if anything, was wrong with the patient and what, if anything, I could do about it. [ibid, pp 288 - 294]
When I got this book, I had to put the world on pause while I read it cover to cover.

Up next in this inquiry into "The Art of Medicine."


A voluminous history. A very interesting read. It's where I got the Voltaire quote that comprises the title of this post.
ABSTRACT: 
There is no such thing as Chinese, Hindu, Muslim, or European physics or chemistry. Why then are there distinct schools of medicine (Ayurvedic, Chinese, homeopathic, etc.)? We find the answer in the differing tasks, which natural and medical sciences perform. Physicians interact professionally with patients and derive material benefit. The patient seeks the service of the designated best healer within the limits of affordability for cure and not for testing the merit of science. If one system fails, the patient tries another, and there is a stream of assuring healers ranging from spiritualists to specialists. This environment is favored by the limits of medical science itself, which is further compounded by unsatisfactory institutions of medical care. Although modern medicine has differed from other schools of medicine (Ayurvedic, Chinese, homeopathic, chiropractic) throughout history, especially since the dawn of the twentieth century, the healing ability of modern medicine is very recent; and here too, with the exception of surgery and supportive therapy, even common diseases such as diabetes and hypertension can be controlled but cannot be cured. Consequently one may expect modern and other schools medicine to co-exist in a mutually hostile relationship for a very long time.

SCIENCE AND SOCIETY 
In general, scientists live in their exclusive world from which general public is excluded. Pythagoras had a strict rule of secrecy for his school, and one of the pupils was drowned because he violated the rule of secrecy of the school. This was fortunately replaced by a trend of public discourse about scientific findings. Many discoveries were publically announced. Darwin’s book on evolution was intended as much for public as for biologists. In the twentieth century, however, science became largely confined to the laboratories, as far away from public as possible. Findings were published in science journals exclusively for scientists. Scientists were no more involved in creating a culture of science. 

It is redeeming to note that modern science, including medical science, is beginning to recognize the significance of interaction between scientists and general public; and important media, both print and television, are beginning to highlight scientific discoveries in open channels. On the other hand, modern scientific research has become very technical. and most of the publications in prestigious journals like Nature and Science are incomprehensible even to scientists in different fields. The cautious note by Yves Quéré (2010) that “academics must engage with society” is a welcome development. Hopefully, all major journals would find a way of communicating with public at large in creating a culture of science and public awareness about scientific medicine...

“Life is short, and the Art long; the occasion fleeting; experience fallacious, and judgment difficult.” - Hippocrates, Aphorisms
"ART OF MEDICINE?" WHERE DOES "PHILOSOPHY" COME INTO PLAY?

Recall Bunge:

At first sight, medicine is alien to philosophy, since the former attempts to heal, or at least to alleviate pain, whereas philosophers analyze and systematize very general ideas, such as those of reality, knowledge, truth, and the good. In his Ancient Medicine, Hippocrates (430– 420 B.C.) warned against philosophy. However, arguably, he only rejected the fantasies of the pre-Socratics, in particular the Pythagoreans, who had strongly influenced his precursors. Half a millennium later, his great disciple Galen opined that “the best doctor is also a philosopher.” 

As a matter of fact, medicine has always been saturated with philosophy, if only because medics cannot help using general ideas, such as those of reality and truth. Let us see how any contemporary physician philosophizes during a routine clinical examination. When the patient appears, the medic takes it for granted that she is a real being (ontological realism) who comes for help, something the doctor is willing to offer to the best of his ability and in accordance with the Hippocratic precept (humanism). To find out what ails her, the physician starts by asking her certain questions, whereby he tacitly admits that there is something he can get to know (epistemological realism), as well as something he can do to help her (praxiological optimism). 

Thus, the contemporary physician does not believe that diseases are sent by a deity as punishment for sins, or by a sorcerer for sheer malice, and he regards medicine as an ars vivendi, not an ars moriendi. Moreover , he knows that death is the natural end of life, not God’s punishment for Adam’s original sin. In short, the modern medic adopts tacitly a secular worldview, and relies on biology rather than on theology. However, let us go back to the doctor’s office. 

The patient’s replies to the doctor’s initial questions may prompt additional questions, as well as a look at the patient’s clinical history, which nowadays is just a click away — an ambivalent fact, because it results in the physician’s looking more at the screen than at the person. But, far from believing everything the patient tells him, the doctor may doubt some of it (methodological skepticism). And he will try to translate into signs or objective indicators the symptoms that the patient feels — for instance, pains into lesions. Such translation of feelings into biomarkers betrays a naturalist view of disease, that is, the thesis according to which sickness symptoms are the subjective correlates of morbid bodily processes. To carry out such translations, the physician may have to use elements of the so-called medical technology, from the humble stethoscope to the sophisticated MRI (magnetic resonance imaging) apparatus. And he won’t forget that there are neither isolated organs nor patients in a social vacuum (systemism). 

As the medic absorbs the stream of data pertinent to the medical problem at hand, he keeps forming, evaluating, discarding, and replacing educated guesses (hypotheses about the nature of the disease and its possible causes). Zigzagging between data and hypotheses, he eventually hits on the conjectures that seem most plausible in the light of his knowledge and experience as well as of the data he has just collected...

To what extent does introspective acuity borne of fluency in the Humanities (e.g., literature, philosophy) inform clinician competency (inclusive of focus on and adeptness with respect to the "healing" that the patient wants)? Or, does scientific/technical competency suffice (with the curriculum updated simply to include facility with digital technology and its informatics traffic)?

Recall, again, that the roots of the word "philosophy" are "philo" ("filial," love of, affection for) "sophia" (knowledge, truth).

WHAT OF EMOTION? THE IMPACT OF "EMPATHY"?

Every hospital dutifully includes the word compassion somewhere in its mission statement. Every medical school rhapsodizes about the ideals of caring. But the often unspoken (and sometimes spoken) message in the real-life trenches of medical training is that doctors shouldn’t get too emotionally involved with their patients. Emotions cloud judgment, students are told. Any component of a curriculum upon which interns slap the “touchy-feely” label is doomed in terms of attendance. Hyperefficient, technically savvy medical care is still prized over all else. 

But no matter how it’s portrayed, and no matter how many high-tech tools enter the picture, the doctor-patient interaction is still primarily a human one. And when humans connect, emotions by necessity weave an underlying network. The most distant, aloof doctor is subject to the same flood of emotions as the most touchy-feely one. Emotions are in the air just as oxygen is. But how we doctors choose— or choose not— to notice and process these emotions varies greatly. And it is the patient at the other end of the relationship who is affected most by this variability...

No one questions whether empathy is important for medicine, but there is a debate as to whether empathy (or lack thereof) is innate or something that we learn along the road of life. It’s clearly some combination of both, but it is intriguing to consider the relative contributions...
Smack square in this debate over whether empathy is innate or learned is the consistent and depressing observation that medical students seem to lose prodigious amounts of empathy as they progress along the medical training route. Something in our medical training system serves to stamp out whatever empathy students bring with them on day one. 

The research appears to conclude that it is the third year of the traditional medical curriculum that does the most damage. This is a dispiriting finding, as the third year of medical school is the one in which medical students take their first steps into actual patient care. For most students, the third year of medical school is eagerly awaited. After two long years sitting in classrooms, you get to actually do what it is that doctors do— be in hospitals, take care of patients. One would think that these first steps into real patient care would bring forth all the idealism that drove students to medical school in the first place— idealism that is sorely tested in the first two years of memorizing reams of arcane facts. 

But the reverse seems to occur. After their seminal clinical experiences involving real contact with real patients, medical students emerge with their empathy battered. Their ideals of medicine as a profession are pummeled by their initiation into the real world of clinical medicine. And it is in this demoralized state that we send them into residency to accrue what are arguably the most influential and formative experiences of becoming practicing physicians. 

Why do medical students lose empathy during the clinical years of medical school? There are likely many reasons. Some are related to the disorientation and fatigue experienced by students as they are thrown into the fire of hospital life— so different from the orderly, clean, controlled classroom life in which they have existed for two years. That student world is cemented along predetermined schedules, explicit curricula, definitive tests. Even if the knowledge requirements are overwhelming— as they are— medical students at least know what to expect, down to nearly every second of their waking hours...

This is nominally a "Health IT blog," or, so it began when I commenced my Meaningful Use Regional Extension Center work in 2010. Why do I continue to press on and out with these broader issues (including my "Third Leg of the QI Stool" ruminations)?

Do they even matter materially?

I obviously think they do. Part of the rationale is illustrated in the book I recently cited, "How Google Works" (scroll down). The fundamental ingredient in their undeniably lucrative Secret Sauce? Unwavering devotion to the wants and needs of the End User. As such pertains to Health IT, I am in utter agreement with Jerome Carter, MD that Health IT must, as a dispositive priority, support and enhance clinical care, via optimization of clinical workflow. Not administrative/billing workflow. Not time-wasting ("Quadrant 3") CQM reporting, or anything else that obstructs the clinician and her healing imperative. Focus unwaveringly on the end user.

To effectively support these end-users, I (and we) need to fully understand every aspect of their worlds. The healer must understand the ailing in every aspect that feeds the SOAPe. Reciprocally, those who work in support of clinicians, and patients under the duress of injury or illness must understand those who seek to effectively diagnose and treat if healing is to occur. Effective communication must happen, and much of that communication is a narrative function, it is not simply comprised of chunks of "structured data" that can be dumped into a SQL database or Excel sheet or SAS table and "mined." We are more than empirical coal seams. We are, IMO, significantly more than the nominal sums, means, distributions, correlations, tabulations, and least-squares polynomial fitted slopes of our "structured data."

Our lives are narratives. Narratives fraught with meaning.

The Art of Diagnosis — Solving the Clinicopathological Exercise
David M. Eddy, M.D., Ph.D., and Charles H. Clanton, M.D.
N Engl J Med 1982; 306:1263-1268May 27, 1982DOI: 10.1056/NEJM198205273062104

Abstract
We analyzed the psychological process by which physicians solve complicated diagnostic problems, such as those posed in clinicopathological exercises. The challenge of differential diagnosis is to select the most probable cause of a patient's condition, yet the size of the problem, the nature of medical information, and the notorious inability of human beings to manipulate probabilities in their heads all conspire against the diagnostician to make it virtually impossible to employ Bayes' theorem in routine diagnosis.


Unable to estimate the desired probabilities explicitly, physicians recast the problem into a form that uses one of their most effective mental skills — that of comparing patterns. A study of 50 clinicopathological conferences published in the Journal suggests that the following six steps are taken to arrive at a diagnosis: aggregation of groups of findings into patterns, selection of a "pivot" or key finding, generation of a cause list, pruning of the cause list, selection of a diagnosis, and validation of the diagnosis.


Although the clinicopathological conference differs in some important ways from real-life diagnostic problems, we belive that the principles described here closely resemble those used in practice. Properly selected clinicopathological conferences are excellent windows through which to study diagnostic reasoning...
The problem
The formulation of the differential diagnosis is one of the most important and intellectually challenging aspects of medical reasoning. When the clinician and counters a patient, the clinician faces a vast amount of information: the patient's lifelong personal and medical history; the patient's report on the current medical problem; and the results of numerous examinations, procedures, and tests. In addition to this information the clinician must have a tremendous amount of knowledge about health and disease. Somehow, seasoned clinicians are able to sort their way through the details, clear the confusion, and make the diagnosis.

Ideally, to select the most probable diagnosis, physician needs to calculate and compare the probabilities of various diseases that could have caused the patient signs and symptoms...
Firewalled :( That's the bulk of what I could get at. Looks like there is discussion of Bayesian anterior/posterior inference considerations, which remain insufficiently understood and deployed.

SATURDAY UPDATE

We are inexorably drawn by much of the foregoing back Down into The Weeds'...

A simple example will illustrate medicine’s missing foundation. Consider a person with chest pain. Careful review of the literature shows that a practitioner investigating this symptom needs to take into account approximately 100 diagnostic possibilities, involving most medical specialties. Each diagnostic possibility is definable as a combination of simple, inexpensive findings from the history, physical and basic laboratory tests. Checking all of the findings for all of the diagnostic possibilities results in approximately 440 findings on each patient. Each positive finding suggests one or more of the diagnostic possibilities. Each patient’s particular combination of positive findings can be matched against all of the combinations of findings representing the diagnostic possibilities for chest pain. The output of this matching process is an individualized set of diagnostic possibilities, plus the patient’s positive and negative findings for each. These findings constitute initial evidence for and against each possibility. The total set of possibilities (i.e. those for which at least one positive finding is made) represents the diagnoses worth considering for that patient. External tools generate this output by simple matching, without dependence on the fallible minds of costly physicians. The tools distill this output from the accumulated experience of countless patients and practitioners—experience that would be otherwise lost.
 

This meticulous matching process is feasible only with software tools. The minds of physicians do not have command of all the medical knowledge involved. Nor do physicians have the time to carry out the intricate matching of hundreds of findings on the patient with all the medical knowledge relevant to interpreting those findings. External tools are thus essential. But the tools are trustworthy only when their design and use conform to rigorous standards of care for managing clinical information.

Without the necessary standards and tools, the matching process is fatally compromised. Physicians resort to a shortcut process of highly educated guesswork. They begin with guesses about diagnostic possibilities that might account for the chest pain. Sometimes very sophisticated, these initial guesses lead to further guesswork about what to check during the initial history, physical examination and laboratory tests for investigating whatever diagnostic possibilities come to mind. And then physicians make more guesses about what the data mean, which in turn shapes their judgments about what further data to collect. Varying from one physician to another, these highly educated guesses are not explicit— physicians do not carefully record their thinking or the information they take into account. Inputs to decision making are thus undefined.


We use the term “guesses” because these key initial judgments are made on the fly, during the patient encounter, based on whatever enters the physician’s mind at the time. That mind may be highly informed and intelligent, but inevitably its judgments reflect limited personal knowledge and experience, and limited time for thought. Euphemistically termed “clinical judgment,” physician thought processes cause a fatal voltage drop in transmitting complex knowledge and applying it to patient data. The outcome is that the entire health care enterprise lacks a secure foundation.


Equally insecure are the complex processes built on that foundation: decision making, execution, feedback and corrective action over time. Responsibility for all these processes falls on the mind of the physician. Here again the mind lacks external tools and accounting standards for managing clinical information.


Medical practice is thus trapped in a subjective realm. Unlike scientific practitioners, medical practitioners do not operate in an objective realm, where the contents of thought and knowledge exist independently of the individual mind, a realm where knowledge can be reliably transmitted and applied, where new knowledge can be rapidly translated into practice, where all knowledge can be tested against patient realities. Isolated from this objective realm, the mind becomes a negative force, a cause of confusion and disorder. Physicians are not equipped to fulfill their immense responsibility safely and effectively. Other practitioners are not equipped to share that responsibility with physicians. Patients are not equipped to work effectively with multiple practitioners, nor to assume the ultimate burden of decision making over their own bodies and minds.
Third parties are not equipped to create order out of this chaos. Practitioners and patients are not accountable for their own behaviors, while third parties are left free to manipulate disorder for their own advantage. In short, essential standards of care, information tools and feedback mechanisms are missing from the marketplace. These missing elements are in large part already developed (see parts IV and VI below). Yet, the underlying medical culture does not even recognize their absence. This does not prevent some practitioners from becoming virtuoso performers in narrow specialties or skills. But their virtuosity is personal, not systemic, and limited, not comprehensive. Missing is a total system for enforcing high quality care by all practitioners for all patients... [pp. 2-3]
In Chapter VIII, Messrs. Weed aim sharp fire at the still rather static prevailing medical education paradigm.
Medical Education and Credentialing as Barriers to Progress
A. Extending the health care reform agenda to medical education and credentialing

1. A century of stagnation

Productive use of advanced medical knowledge requires an integrated system of care with a rational division of labor in which all participants see clearly how their roles contribute to solving medical problems. All participants should be able to avail themselves of knowledge that individually they do not possess, practitioners should not be permitted to perform at a level beyond their demonstrated competence, and no group of practitioners should be able to pursue its own interests to the detriment of the larger system of care.  
Progress towards a rational division of labor within an external network of knowledge tools is largely absent. Isolated advances are not evolving and coalescing into an integrated system of care. We all are trapped in a non-system, where an elite class of practitioners is permitted to rely on limited personal knowledge and intellect. Graduate medical education and credentialing protect this physician elite from competition that could otherwise reshape medical practice. The health care system has thus been remarkably slow to adapt to the new environment created by modern information technologies. And that environment is still developing. Our culture is still working out the right division of labor between human cognition and external information tools. The subculture of education, however, lags far behind the domains of science and commerce in that development. [p. 195]
That entire chapter takes my breath away, notwithstanding that its critique of pedagogy did not delve explicitly into "liberal arts / humanities" literacy considerations. But, consider the closing words of the book [pp. 265-266].
Appendix b: The Art of Medicine:
Finally you may ask where - does the art of medicine fit in? Surely no system will make one kind, thoughtful, or sympathetic: to care deeply about the plight of others is a quality not dispensed in manuals of any type. But to say that the art of medicine is not dependent on a great deal of discipline and order is to miss perhaps the true understanding of what underlies art in any form. The physician as well as the musician and poet should read the following words of Stravinsky and at least recognize the possibility that they also apply to him:

A mode of composition that does not assign itself limits becomes pure fantasy. The effect it produces may accidentally amuse, but is not capable of being repeated. The creator’s function is to sift the elements he receives, for human activity must impose limits upon itself. The more art is controlled, limited, worked over, the more it is free.
 

As for myself, I experience a sort of terror when, at the moment of setting to work and finding myself before the infinitude of possibilities that present themselves, I have the feeling that everything is permissible to me. If everything is permissible to me, the best and the worst; if nothing offers me any resistance, then any effort is inconceivable, and I cannot use anything as a basis, and consequently, every undertaking becomes futile.
 

What delivers me from the anguish into which an unrestricted freedom plunges me is the fact that I am always able to turn immediately to the concrete things that are here in question. I have no use for a theoretic freedom. Let me have something finite, definite—matter that can lend itself to my operation only insofar as it is commensurate with my possibilities. And such matter presents itself to me together with its limitations. I must in turn impose mine upon it. So here we are, whether we like it or not, in the realm of necessity. And yet which of us has ever heard talk of art as other than a realm of freedom? This sort of heresy is uniformly widespread because it is imagined that art is outside the bounds of ordinary activity. Well, in art as in everything else, one can build only upon a resisting foundation: whatever constantly gives way to pressure constantly renders movement impossible.
My freedom thus consists in my moving about within the narrow frame that I have assigned myself for each one of my undertakings.
Interesting.
"Surely no system will make one kind, thoughtful, or sympathetic: to care deeply about the plight of others is a quality not dispensed in manuals of any type."
No, those kinds of character traits are to be acquired elsewhere in the educational system (and outside its walls). Is healthcare delivery irreducibly both science and "art" (the latter facet inadequately understood and defended), or is it merely a suite of dispassionately applied, increasingly complex technical crafts, driven by numbers and codes and cognitive "reasoning" skills? I'll repeat my prior question:
"To what extent does introspective acuity borne of fluency in the Humanities (e.g., literature, philosophy) inform clinician competency (inclusive of focus on and adeptness with respect to the "healing" that the patient wants)? Or, does scientific / technical competency suffice (with the curriculum updated simply to include facility with digital technology and its informatics traffic)?"
 It's perhaps worth mentioning that Damasio points out in Descarte's Error that one has to care about reasoning. Things are not simply "facts and logic over here; emotion over there."

Ahh... what do I know? All I ever wanted to do was be a guitar player.
