What’s the solution? The late medical humorist and author Robert Eliot, M.D. was fond of telling the joke about a man who cut his finger with a kitchen knife and went to the ER. After going through the main entrance he came upon two doors. The sign over one door said “critical” and over the other door “stable.” He went through the door marked “stable” and down a long corridor before coming to another set of doors, one of which was marked “illness” and the other “injury.” After going through the “injury” door he came to another set of doors, one of which was marked “blow” and the other “cut.” He examined at his finger, decided that the injury was indeed a cut and went through the appropriate door. The next pair of doors was marked “extremity” and “torso.” He opened the door marked “extremity”, walked down a corridor and found two doors marked “bleeding” and “not bleeding.” Because the bleeding had stopped by this time he went through the door marked “not bleeding” and found himself in the parking lot. Good case management?
Equally humorous was the Institute of Medicine’s solution recently published in the New England Journal of Medicine which said, in effect, “hospitals: cease patient boarding and ambulance diversion by just being efficient.” What’s humorous and patently absurd about this mandate is that hospitals have been under maximum pressure to improve efficiency and patient flow for 23 years. Thanks to the prospective payment system (DRGs) implemented in 1983 their very survival already depends on efficient patient flow. My previous post criticizing the Institute of Medicine is here. More critical commentary on the IOM recommendation can be found at DB’s Med Rants and Kevin M.D.
Hospitals can cut down on ambulance diversion with aggressive bed control strategies, but busy hospitals have not been able to eliminate it. St. Louis University, for example, despite intensive process changes geared specifically toward the problem, still diverts ambulances on average between 30 and 60 minutes a day.
Hospital administrators, reluctant to divert ambulances, sometimes allow their ERs to accept patients even when all inpatient beds are occupied. This results in worsening of crowded conditions since patients in need of admission have no place to go and must be “boarded” until an inpatient bed becomes available. Such boarding can take place wherever space happens to be available such as hallways, one day surgery or observation units or the ER itself with the location determined in many cases by staffing. In some states, however, regulations may dictate where patients can be placed.
Dealing with such conditions requires a spirit of cooperation and a seamless relationship between the ER and the rest of the hospital. Unfortunately, if some of Grunt Doc’s commenters or a recent thread over at the UCSF Emergency Medicine Listserve are any indication there is a culture of finger pointing, an “us against them” mentality which will prove counter productive to any solutions for ER crowding. I commented about this culture of blame here.

What’s different about the new strain? It has a mutation which causes it to produce markedly increased quantities of toxin. This has resulted in an increase in treatment failure, relapse and mortality. The latest review on this hospital scourge was published in the November 21 issue of Annals of Internal Medicine.
The year 2006 saw the publication of three new resources in perioperative medicine which merit inclusion in this year’s top ten list:
The proceedings of the second annual Cleveland Clinic Perioperative Medicine Summit appeared in a September supplement to CCJM. There’s a world of helpful stuff there.
Guidelines for perioperative pulmonary risk assessment and management were developed by the American College of Physicians and appeared in the April 18 issue of Annals of Internal Medicine.
After a frustrating back-and-forth on just which patients should receive perioperative beta blockers the American College of Cardiology helped settle the issue, at least for now, with new guidelines.
Perhaps the best known forms of outsourcing are remote transcription services and remote interpretation of images. A more novel and ambitious form of outsourcing is the eICU. It is believed that the first eICU in the United States was started several years ago at Sentara Health Systems in the Hampton Roads area of Southeastern Virginia. Evidence suggests that mortality and length of stay in ICUs are improved with a dedicated intensivist model in which there is mandatory care of all patients by a critical care specialist. The Leapfrog Group and others which set standards for quality in health care recommend the dedicated intensivist model. The major problem in implementation is the shortage of critical care specialists. It is estimated that there may be fewer than half as many critical care specialists as there are hospitalists. The eICU may be a way to close this gap in implementation. Evidence that eICUs improve mortality and utilization is beginning to accumulate. This study in the journal Critical Care demonstrated that improvements in outcomes derived from the use of an eICU were similar to those reported for the dedicated intensivist model of on site critical care specialists.
How does it work? This description of the eICU at Sutter Health seems fairly representative. Critical care physicians and ancillary staff monitor electrocardiographic and physiologic data in real time, as well as laboratory data via direct computer interface from a remote location, perhaps hundreds of miles away. The eICU staff communicates with on site physicians and nurses via direct audio and video links, telephone hotlines and computer text messages. High resolution cameras zoom in to check patients’ pupils, examine the skin and read labels on infusion bags. Thanks to real time interface with the lab, the remote team will be aware of critical results before anyone else and when the contractual arrangement with the on site physicians allows, they can give orders directly to the on site nurses. Because the eICU control room is manned “24/7” by staff who are free of the competing demands of hospital rounds and the distractions of pagers the response time to abnormal lab tests and hemodynamic disturbances is shortened.
There are limitless possibilities. The eICU doctors can access physician orders, medication records and progress notes and thus can make daily reviews for compliance with evidence based quality “bundles.” Prompts from the eICU staff to the on site doctors thus have the potential to enhance compliance with DVT prophylaxis and other underutilized quality measures.
The skeptic in me realizes that bright ideas tend to be implemented, sometimes with irrational exuberance, ahead of evidence. The early promise of the eICU needs validation by more studies. In the meantime will it be viewed as a welcome practice enhancement or as something Orwellian? It all depends on your attitude.

Although the concept is simple, implementation seems to have proven difficult judging from some of the forums I read. For many initiatives on patient safety big ideas tend to precede evidence, but in the case of medication reconciliation evidence is already trickling in that the process can save lives.
Top 10 issues in hospital medicine for 2006---issue 8: two debates put to rest concerning ALI and ARDS
Thursday, December 28, 2006
I ranked the state of the hospitalist movement first last year. I’m ranking it number 10 this time because 2006 saw no movement-defining developments.
Economic pressures a decade ago created a niche for the movement in areas of heavy managed care penetration. The pressures of managed care relented, but a new niche was created as more and more primary care physicians chose to increase their efficiency by dropping hospital practice. These physicians can more easily stay on schedule in their offices, a patient satisfaction advantage counterbalanced by some patients’ frustration with receiving in patient care from strangers.
Some feel that hospitalist medicine is opposed to the agenda of primary care. Robert Wachter, M.D., a leader in hospital medicine, disagreed in a recent interview in Internal Medicine World Report: “Rather than feeling that hospitalists are another nail in the coffin of primary care, I hear from many primary care doctors that hospitalists have helped them tremendously. They realized long ago that they simply could not take care of sick hospitalized patients and manage their office practice simultaneously, and hospitalists have helped them make their jobs more survivable.”
Professional satisfaction seems to be shifting in favor of hospital medicine. It’s at an all time low in traditional primary care practice leading more and more internal medicine trainees to choose hospital medicine. According to Wachter, Society of Hospital Medicine surveys show a high rate of professional satisfaction among hospitalists. Wachter also predicted that the number of hospitalists needed may reach 50,000, a higher estimate than those made previously.
A few decades ago the hospital was a jungle, a combat zone inhabited by people with competing agendas and a culture of blame. Booby traps posed dangers to patients at every turn requiring the vigilance of the “superdoc” to head them off. The dream for the hospital of tomorrow is that of a safe place where a nurturing spirit of teamwork pervades the facility and computer enhanced system improvements all but eliminate errors. Movement along this path may gradually shift the role of the hospitalist from superdoc to systems management team member. But we’re not there yet. It’s a slow journey and in 2006 we’re somewhere between The House of God and the safe place. Systems improvement is too early in its development to solve the problem of patient safety. There will be a role for vigilance on the part of the individual hospital physician for years to come.

David Spodick, M.D., professor of Medicine and Cardiology at the University of Massachusetts, comments on under appreciation of the electrocardiographic P wave in Internal Medicine World Report, making the following points:
- Analysis of the P wave is often neglected in discussions on electrocardiography.
- Most P wave abnormalities are defined by P wave duration, the upper limit of which is 100ms.
- P wave duration in excess of 100ms constitutes atrial conduction block, specifically intra-atrial or, more likely, inter-atrial block.
- Atrial conduction blocks indicate increased risk of atrial fibrillation and stroke, and may reflect left ventricular dysfunction.

What caught my eye was the picture of the pendulum used during the Reiki treatment which, according to the caption, swings in accordance with the flow of the patient’s life-force energy. Now if the body’s energy field moves a pendulum that energy can be harnessed. Use the pendulum’s motion to turn a small generator and store the electricity thus produced. We’re not talking about a large quantity of energy in one Reiki session---maybe enough to charge a patient’s hearing aid battery.
Dr. Baugh’s credentials are impressive. She’s a diplomat of the American Board of Internal Medicine and a former assistant professor of Medicine at Vandy. What do such mainstream credentials bring to the world of woo? According to Dr. Baugh “….our approach to alternative medicine is a little different because it's more scientific.”
Well, if they want to be scientific I suggest they make some controlled observations on the motion of that pendulum. They could start by suspending it over a patient from an inanimate structure rather than the hand of the practitioner. Suspend another pendulum over an unoccupied exam table to control for ambient air currents. Repeat the experiment in other settings with independent observers. It wouldn’t be rocket science. It might make a nice junior high school science project, but it this stuff really works there’s a Nobel Prize in it for someone along with a million bucks in the Randi Challenge.
It’s mysterious to how the energy works. As the Reiki practitioner’s hands move this way and that over the patient how does one keep track of where the energy goes? The Tennessean article offers us hard data on the energy flow of Dr. Baugh’s patient. She lost 20 pounds. If stored as fat that translates into 81,720 Kcal or 34,183,280 joules of energy which left her body. That’s 9.5 kilowatt-hours---not bad if you can harness it.
But I digress. I won’t be convinced until I see that pendulum experiment. I confess I’m not optimistic. I think it’s all woo. The launch of the Vanderbilt center is disturbing. Vanderbilt is on the cutting edge of science yet very traditional. I thought it would be the last bastion of scientific integrity, the last place on the planet where you’d find woo. Is there any hope?

And what would that mean for the medical school curriculum? Just turn students loose with lap tops, subscriptions to Up To Date and lots of patients, I guess. Don’t laugh. It’s not far from a proposal in BMJ a few years ago in which the medical school of the future would train doctors primarily to be information hunters, eliminating lectures and exams in anatomy, biochemistry and physiology.
Dr. Roy believes patients can help close the resulting knowledge gap. Referring to the “reams of paper” patients often bring for their appointments he says: “Since we are now ‘partners’ with the patient in terms of diagnosis and treatment, we need to honor the patient's book of knowledge and provide our best guidance system.” But many patients, 44% in this study, have no desire to seek out medical information for themselves. Of those who do, few have the skills in literature searching and critical appraisal needed to apply the principles of evidence based medicine (EBM), without which clinical decision making becomes flawed. The task of making patient decisions evidence based is onerous, as I once blogged here. Although patients often bring their homework to the clinical encounter I’ve yet to be presented with a rigorous, critically appraised summary of the best evidence. If only it were so! More often I’m presented with a drug ad or the latest New York Times article---hardly evidence based.

Many of mainstream medicine’s conventional treatments are not evidence based. Aren’t they a form of woo?
No. Although some conventional methods fail to measure up to best evidence they are at least based on known anatomy and physiology. They have some plausibility in the observable biophysical model in contrast to the “vital forces”, nebulous “energy fields” and “non-local powers of the mind” which are characteristic of woo.
You seem to focus a lot of your criticism on woo. Isn’t non-evidence based conventional medicine harmful too?
Yes, of course. Moreover, there are harmless forms of woo just as there are harmless conventional breaches of EBM. All departures from best evidence are problematic and need to be addressed, whether woo-based or not.
Then why make a distinction?
Because of important differences in the ways the problems manifest themselves. Mainstream medicine applies a double standard and that’s what I’m trying to expose. People in the mainstream are appropriately critical of conventional deviations from best evidence and are trying to correct the situation. But due to the nature of the problem---a complex interplay of system and cognitive failures---the fix is not easy. In contrast (and here’s where the real hypocrisy comes in) mainstream medicine uncritically embraces woo, applying to it a much easier evidentiary standard and often no standard at all. The remedy for the problem of woo would be much simpler, too. Mainstream medicine could simply say no. Woo, by definition patently implausible, is easy to spot. There’s nothing complicated about it. It’s not a system problem. It’s there in mainstream medicine purely by choice. That fact raises another important distinction. If mainstream departure from EBM is a complex system problem and woo is there by choice then woo constitutes a more serious ethical problem.
But if patients want woo shouldn’t we let them seek it out?
By all means. We must respect our patients’ right to choose, and there are plenty of woo facilities outside the mainstream which can accommodate them. It’s quite another thing, though, if we misinform patients by putting our mainstream reputations and credentials behind false promotions. It’s just plain dishonest.
I’ve been reading all these statistics about the increasingly large numbers of patients who are seeking alternative medicine, or “woo” as you call it. They’re even paying for it out of their own pockets. Shouldn’t we in mainstream medicine accommodate them?
Not unless we decide all we’re interested in is taking their money, or in basing best practice on a popularity contest. These don’t strike me as good reasons.
Some woo based methods seem to be little more than relaxation and exercise techniques. What’s wrong with that?
Nothing, as long as you don’t make false claims. Go ahead and recommend relaxation and exercise, but if you promote it, for example, as Qigong you’re promoting all the paranormal theories of “vital energy healing” that go with the package. If you’re a mainstream medical practitioner and put your good name and credentials behind such false claims you’re being unethical.
Now, will this settle the misunderstandings once and for all (as Dr. RW braces for the next salvo)?

If you note strange goings on when the social worker pays your patient a visit you might want to read this.
These off label uses, at times controversial, have created challenges for hospitals at the institutional level due to cost concerns. This paper from the American Journal of Health System Pharmacy describes how one academic institution, the University of Virginia Health System, addressed the problem. Evidence for various off label uses is cited and proposed guidelines for on and off label uses are provided.

How can patients be sure if a treatment is valid? In many cases they can’t----they have to trust us. That’s the whole point about fiduciary duty. Many of the woo providers of the world are easy to spot because they make no pretense about being based on Western science. What the patient sees is what the patient gets. The ethical problem, the real deception, comes from the mainstream’s more subtle promotion, hiding the woo behind its reputations and scientific credentials. It’s one thing when the shaman down the street tells patients they need a colon cleanse. It’s quite another thing, and far more concerning when Vanderbilt----Vanderbilt, mind you---promotes Qigong or UCSF promotes herbal tea to “boost the immune system.”
Emily correctly points out that conventional medical treatments aren’t always evidence based. She asks “Is that not, in effect, a form of woo, too?” The breach between evidence and practice to which she refers, let’s call it the quality chasm, while every bit as serious as woo, is not in fact woo in most cases. The quality chasm is not a result of outlandish or implausible claims, (e.g. that water has memory) and that’s what distinguishes it from woo. The quality chasm results from an extremely complex interplay of cognitive and system barriers to the consistent application of best evidence in practice. Mainstream medicine recognizes the need for widespread system change and promotion of evidence based medicine. Although there’s no simple fix to the quality chasm, many in mainstream medicine are trying, which is in ironic contrast to the fact that mainstream medicine also increasingly promotes woo. For the mainstream, especially academic medicine, to promote woo is to engage in unethical scientific pretense and active deception of patients. It seems to me that the solution to woo in the mainstream is much simpler than the quality chasm: Mainstream medicine just needs to say NO.

To that I’ll just add that there might be a wee bit of a conflict of interest here---“science” with an agenda, perhaps. At least it was disclosed. Although the author describes himself as a “Reagan revolution fanatic” he believes George W. is “beyond the pale.”

The authors, acknowledging weaknesses in this study, were cautious in their conclusions and called for further studies, but this really concerns me. My take home messages are 1) in the early months following coronary stenting consider using a statin that is not a substrate for CYP3A4 and 2) upon discharge after coronary stenting send your patient straight to the drug store and consider dispensing a couple of clopidogrel tablets!

Lyme disease has been quack-fodder for too long and guidelines such as these are badly needed.

And so it is with medicine. I know it’s dangerous to compare medicine with auto repair, but there may be a useful analogy here concerning the responsibility of a person in a position of trust (and we’ll restrict the comparison to just that). In medicine we sometimes call it fiduciary duty. Our particular fiduciary duty to patients is to be and do what all those certifications and accreditations lead them to expect. They expect expertise, and for that expertise to be applied honestly. Moreover, the general public perception of that expertise, at least for us in mainstream medicine, is that it’s based on science. Most patients, when offered a particular treatment, believe that. Lacking any desire or ability to verify it independently they simply trust that it’s so. This presents an ethical problem when unscientific treatment methods are offered to patients (call it alternative medicine, call it what you will; I think Orac’s term “woo” should serve our purpose here as well as any other).
Now, in order to really parse the ethics of woo I would propose two broad contextual categories: stand-alone woo and integrated woo. Here are my definitions. Stand alone woo: woo which is offered by a clinic or institution as its major method of treatment. Integrated woo: woo which is promoted by “mainstream medicine”, accounts for a relatively small fraction of total treatment offerings and is more likely to be disguised as science.
This definition is somewhat imprecise and there are fuzzy areas. Some stand-alone woo providers, for example, have “MD” after their names and purport to “integrate” the best of woo with the best of conventional medicine. Nevertheless I place such institutions in the category of stand-alone woo because they major in woo, and that fact is usually patently clear to patient-shoppers. The average consumers know it when they see it.
Integrated woo presents the more serious ethical problem because the mainstream institutions (like, I’m embarrassed to say, my beloved medical alma mater Vanderbilt) are putting their good names, their certifications and accreditations, behind the woo they promote. Patients come, most of them anyway, expecting scientifically based treatment, and may be none the wiser when offered woo. After all, mainstream science-based providers wouldn’t promote something unscientific, would they? Why should patients expect them to? When they receive treatment based on an eclectic, mystical world view it's disguised, implicitly or explicitly, as science. The woo is more insidious, more subtle, which is why it’s all the more egregious. Patients are flat out being deceived unless, as recently suggested by anti-pseudoscience warrior Wallace Sampson, they receive explicit informed consent about the nature of the method being offered.
I have less of an ethical problem with the stand-alone woo providers. For one thing, maybe they don’t know any better. I’m convinced that they (many of them anyway) truly believe in what they do, are trying to make an honest living and have a heart for helping patients. (This is in contrast to the mainstream hospitals and medical schools which know better, or should know better). Secondly, the stand-alones, many of whom are openly dismissive about western science, aren’t nearly as pretentious about any scientific underpinnings as are the mainstream folks. As a consumer you know what you’re getting with the stand-alones. It’s caveat emptor, like going to the Griner brothers’ garage.
So, I say let the stand-alones compete in the open market place of ideas. To those in the mainstream for whom this shoe of integrated woo fits, clean it up. To medical school faculty who remain silent while the largest and most influential activist group of medical students on your campus promotes chelation for everything under the sun that ails a person, wake up. To physicians who care about evidence based medicine, if you see woo creeping into your hospital or clinic, speak out. To those in the mainstream who lend your good name to the promotion of quackery in your institutions, STOP IT! It’s unethical. It’s a violation of fiduciary duty.
A cluster of sleepy little towns not so long ago, we’re morphing into a major commercial center due in large part to Walmart, whose corporate headquarters are here. The resulting business travel has spawned a thriving service industry, and the population growth has outpaced the influx of doctors. So, if you’re looking for a place to hang your shingle, give us a look.

But, hey, this isn’t all that new. You read it here first! Let me add my bias here. I would go beyond what the FDA says, and consider methadone just as I would cardiac drugs known to prolong the QT interval and cause torsade. That is, I would get an ECG at the start of therapy and periodically thereafter. I would pay meticulous attention to interacting drugs and liver function. I would keep an eye on the patient’s potassium and magnesium. Is this overkill? Maybe. But don’t forget, as I mentioned in the post referenced above, that the Center for Education and Research on Therapeutics, a center of expertise on drug induced cardiac arrhythmias, has placed methadone in the highest risk category of QT prolonging drugs.
Although not recognized or denoted as such in those days (rarely mentioned in the world’s literature before 1986 based on my quick Pub Med survey) Libby Zion had the serotonin syndrome.

It’s trendy nowadays at traditional academic Grand Rounds for the speaker to disclose any potential conflicts of interest. Here are mine. I have no financial ties with drug or device companies. A Zithromax clock, a hand me down from National Nurses Day, graces one wall of my office. I have attended about four drug company lunches in the past year. That’s about the extent of any blandishments from Evil Pharma.
Although under appreciated, non-financial conflicts, perceived or real, are just as important as the financial kind. We all have them. I, for example, am a) a Christian, b) a member of the vast right wing conspiracy and c) a staunch adherent to the principles of science. (Note that a is not inexorably linked to b or in opposition to c). I’ve become opinionated and crotchety in middle age and have many biases. But not to worry, dear readers! I’ve done my darndest to keep those biases out of this edition of Grand Rounds. To that lofty end there will be no editor’s choice, best of the best, or best of the rest! Everything included here gets equal billing in hopes that this carnival will be a good time for all.
I’ve restricted my editorial prerogative to adding a running commentary, stream-of-consciousness style, to provide some structure to this incredibly diverse collection of links and perhaps liven things up a bit. I’ll sneak a few opinions in here and there, but you’ll know them when you see them. Well, enough of the preliminaries. There’s some heavy duty blogging to get to, so let’s rock and roll.
Mother Jones suffered through pandemic flu not long ago. Well, an inservice on pandemic flu, anyway. On her day off, no less.
Enjoying the eye candy on the wards? Dr. Derlet of Rural Pediatrics has some sobering advice for health care professionals on what not to wear. Strutting too much of your stuff may turn heads but it lowers patients’ confidence. And that’s evidence based! Worse yet, the credentialers are watching how you dress. Just ask our favorite credentialer Rita over at MSSPNexus blog! Yikes!
Are there moral absolutes? Is there a free lunch? Rohin, author or The Daily Rhino, finds himself in an existential crisis as he ponders these weighty questions after making the transition from student to doctor. It’s tough trying to balance medical student idealism against the allurement of Big Pharma freebies.
Wandering Visitor has some friendly infection control advice in Don’t Get Raunchy with Mr. Open Sores. Trouble is, Mr. Open Sores isn’t likely to tell you he has a problem. Nuff said. While we’re on the subject of taking medical advice, Dr. Nic at Shoe Money Tonight explains why it’s easier said than done.
I can remember being abused as a medical student and house officer, but I thought such abuse went out like the dark ages. Not so according to Anthony Rudine, blogging on the Medscape Med Students blog. In reading his post (recommended by Medscape editor Christine Wiebe) it appears that the grand tradition of med student abuse, like fraternity hazing, is alive and well. Isn’t it about time for a kinder, gentler medical curriculum?
Another Medscape student blogger (again, thanks for the tip, Christine) Ali Tabatabaey, reflects on one year of blogging on his first blogiversary (or is it blogoversary?). Congrats and keep up the good work, Ali!
A wise medical sage once told me that when it comes to being sued there are two types of doctors: those who have been and those who will be. It’s like the Sword of Damocles! Medical student Vitum Medicinus and his classmates are being lectured about the ever present threat. He shares his concerns here.
Ectopia what??? Ectopia cordis---a rare developmental anomaly in which the heart is situated outside the chest. Dr. Anonymous writes about a recent case.
NHS Blog Doctor speaks against physician assisted suicide and euthanasia, sparked by the recent story of another assisted suicide at Switzerland’s Dignitas institute.
RDoctor posts an interview with Emergiblog author Kim, exploring a wide range of nursing and blogging issues. Particularly interesting were her comments on arrogant physicians (they’re becoming an anomaly, she thinks), hospital case managers (nurses and social workers who facilitate discharge planning and troubleshoot financial, social and administrative problems in patient care) and the nurse’s role in facilitating ED patient flow.
And now that the kids have returned to school from Thanksgiving break The Fitness Fixer has some tips for ergonomically smart book carrying.
Now to reflect on matters of the psyche. Sigmund Freud started as a neuroanatomist, and maybe the behavioral sciences are coming full circle. Psychologist blogger Dr. Deborah Serani writes of a recently discovered gene (a variant of the serotonin transporter) which is associated with mental illness and enlargement of a group of thalamic nuclei known as the pulvinar, a deep region of the brain associated with emotions. Now there are those who might say this is all just pseudoscience. I’m waiting for them to demonstrate a neuroanatomic locus for engrams. But I digress. I think this discovery is pretty cool.
By the way, Dr. Serani has been a technical advisor for “Law and Order: Special Victims Unit.” (My wife is addicted to that show). I’ll be browsing her blog with interest in the near future. There’s a post on the psychological aspects of “If I Did It” and other interesting stuff.
Tempering our enthusiasm for bench-to-bedside correlation in the behavioral sciences, Health Business Blog reminds us that we have a ways to go, particularly in the area of pediatric psychiatric diagnosis.
Are we really what we eat? On some level, yes. The Wellness Tips blogger takes it literally and recommends organic food. Healthy? I’m sure, but rather spartan, it seems to me. I like the advice given in the poem Desiderata: Beyond a wholesome discipline, be gentle with yourself.
Oh, those perverse incentives! Everybody’s talking about conflicts of interest these days. The popular buzz in medicine is almost exclusively focused on the conflicts that arise from the influence of Big Pharma. But Number 1 Dinosaur has a thing or two to say about another conflict: ordering unnecessary tests to pad the bottom line. Dino’s insightful (or should I say inciteful---read what his commenters had to say!) and entertaining post and its update bemoan the decline of basic clinical skills and the use of technology as a substitute for clinical reasoning.
Now for your fix of hardcore clinical content---
Unbounded Medicine presents a case, along with some interesting images, of Tetralogy of Fallot.
Corpus Callosum cites a small study from the American Journal of Medicine suggesting that baclofen is as good as diazepam for the treatment of alcohol withdrawal. It’s not enough evidence to change current practice. At the risk of sounding trite, more studies are needed.
Inside Surgery has a nice series of posts on seizures in the ICU. Here’s Part 7, the most recent post. You can access the rest from the main page.
Dr. Kenneth Trofatter of Fruit of the Womb presents a case of cervical incompetence and discusses the possible role of insulin resistance syndromes.
And for patients and families---
Dr. Auerbach, blogger of Medicine for the Outdoors, offers some tips for the safe buying and handling of fresh produce and Cancer Treatment and Survivorship has some timely advice this holiday season on traveling with supplemental oxygen.
Now for some exciting news about the medical blogosphere. Dr. Ves Dimov, Clinical Assistant Professor at Cleveland Clinic Lerner College of Medicine and author of the Clinical Cases and Images blog reports back from the American Society of Nephrology’s Renal Week 2006 where one of his poster presentations (which you can view on the blog entry) dealt with medical blogging as an educational tool for students and house staff. The medical blog is emerging as an educational vehicle in no small part due to the efforts of Dr. Dimov. Nice work!
Second opinions come in many forms. Some patients go doctor hopping. Grunt Doc saw a patient the other night who went drugstore hopping.
Our “From Bench to Blogosphere” segment features docinthemachine with some original research he recently presented before the American Association of Gynecological Laparoscopists on a little appreciated variant of Asherman’s Syndrome along with discussion about potential applicability to the treatment of other gynecological disorders.
Kim at Emergiblog discusses the progression of signs and symptoms along the road to burnout and what to do about it. She’s been there and done that.
Tundra PA describes a case of steam bath boil. The culture came back MRSA. Given that it was sensitive to TMP-SMX it’s almost certainly one of the new community associated strains (CA-MRSA). Looks like it’s made its way up to the villages of Southwest Alaska!
When less is more: Insureblog comments on a study suggesting that more intense care doesn’t always help patients with chronic illness and wonders how patients would respond if the results were widely known.
Amy at Diabetes Mine writes about the bright future of continuous glucose monitoring systems. Unfortunately she missed out as a study subject for Abbott’s latest device because of skin sensitivity to the adhesive patch!
The folks at Anxiety, Addiction and Depression Treatments have posted some information on drug-grapefruit interactions. It’s not confined to psychiatry drugs, by the way. Felodipine, which I take for high blood pressure, is noted for the interaction. Although grapefruit might give me a bigger bang for my buck by exaggerating the effects of the medicine (it inhibits gut mucosal CYP34A, doubling systemic absorption) it’s too risky. Don’t try it. Always ask your doctor or pharmacist about food-drug interactions!
Susan Palwick, volunteer ED chaplain, describes a particularly difficult shift with several very ill children in Peds Night. A chaplain never knows what a distressed family might want---prayer, affirmation, maybe just someone who will listen.
Well, that’s about it for this edition of Grand Rounds. Don’t miss next week’s edition at The Antidote.

The current fragmentation of ambulatory care will only make this problem worse. Hospitalists are often the ones who start such medications, and therefore have a significant role in secondary prevention. This study suggests a need for more aggressive patient education and case management at discharge.

Second, what's so magic about the ED? Only the ED and OB have rubber walls and are infinitely flexible, to try our best to care for every patient ho needs our help. Except, see, our walls really aren't made of magic rubber, we can't just snap our fingers and make more rooms, beds, monitors or nurses appear. Every patient who should be admitted to the hospital but isn't is a) not getting the specialized nursing care available on the ward where they belong and b) is taking up a bed in the ED we need to see then next 1-12 patients. The linked commenters in the first paragraph give a 'suck-it-up ED' subtext that rankles.
That wasn’t what was intended, so I clarified here. Grunt Doc graciously relented (in my comments). But the finger pointing by some of the ED types in his comments suggested an “us against them” attitude. My clarification post made these points:
Wait a minute---nobody’s blaming the ER here. This isn’t “us against them.” The emergency department is part of the hospital. Their problems are the hospital’s problems, and vice versa. If the ER is overtaxed the entire hospital feels the strain due to extensive overlap and sharing of resources. Concerning whether patients who needed boarding should be boarded in the ER or on the wards I said: There’s nothing written in stone in my mind that such boarding has to take place in the ER unless the patient needs cardiac monitoring.
Well, I figured I’d made that pretty clear until commenter Ryan (evidently an ED provider) weighed in with this straw man: My question to you is why are my halls better then your halls? And then: I ask again why floor nurses are different from the ED nurses.
Look, it’s not a matter of my nurses vs. your nurses, or my hallways vs. yours. I never said it was! Why do ED types seem to want to frame it in adversarial terms? Hospitalists are “on board” with this issue. We’re on the same side. Really. One of the thought leaders at the Southern regional hospitalist meeting in New Orleans a week or two ago said that the Society of Hospital Medicine is committed to helping improve ER throughput. (I wasn’t there but I browsed the syllabus one of my colleagues brought back. Sorry I missed you DB. We’ll hook up one of these days).
You read it first on here over a year ago. I’ll repeat the caveats I posted then:
1) For witnessed VT or VF in the health care setting immediate defibrillation remains the initial modality (remember the electrical phase!).
2) This new thinking does NOT apply to pediatric codes or other arrests of suspected respiratory origin. Rescue breathing remains a higher priority in those situations.

Until recently complementary and alternative medicine (CAM) courses in medical school have been offered mainly as electives. Georgetown wants to take it a step further and “Aim CAM curriculum at all students through required courses.” Plans for integration of woo into the basic science courses read like fodder for late night infomercials: psychoneuroimmunology, stress hormone modulation through relaxation, imagery and breathing regulation and more.

Well, that’s scary----opening up the credentialing process to last week’s disgruntled drug seeker or patients of this ilk. Heck, why not just invite ‘em to attend the credentials committee? By any reasonable standard the evidentiary quality of sites like this is somewhere below garbage in this blogger’s opinion.

Really? What about their belief that traditional Chinese medicine (TCM) has “proven helpful” for cancer, infectious disease, heart disease and AIDS (Complementary Therapies Primer, page 5)? Or that “By activating the electrical circuitry of the body which conduct qi along the meridians, qigong is able to harness the body’s own healing powers (page 7)? And does therapeutic touch really help asthma (page 9)?
While AMSA wants a rigorous evidentiary standard for the products of Evil Pharma the herbs seem to get a free pass (pp 12, 13). Thus cayenne is good for “strengthening metabolism” (were these kids sleeping through biochem?) and preventing colds. Echinacea is recommended for respiratory infections, connective tissue diseases and multiple sclerosis and ephedra “must be used with caution.” (How does one use ephedra with caution, exactly?).
And how about that four day fast? Seems it thins blood, leads to better oxygenation and improves immunity (page 18). Finally, don’t forget good old chelation for everything from cancer to spider bites (page 20).
So, on November 16, go PharmFree and consider the alternatives.

The problem with such thinking is that the study, published in the April issue of Medical Care, is the comparison group: Medicare Advantage, another government run health plan loaded down with the added baggage of managed care.
Nevertheless it will be spun in opposition to the free market.

Perhaps the best known and most reputable physician rating service is Health Grades, a no nonsense, “just the facts” site that requires paid access to view physician ratings. Rate MDs is different. It’s a free wheeling, let it all hang out message board style web site with open access to all. Although users have the option to create an account, it’s not necessary in order to post or view, and commenters do not have to give any identifying information.
According to the FAQ page although patient comments are reviewed for appropriateness they are posted “immediately.” The site owners imply they may delete inappropriate comments, but here’s a sampling of what did not get deleted:
does breast exam for no reason
this doctor is a bully
this man is a joke
I fully blame this doctor for my aunt’s death
--just a creep!
trained his staff to lie---------
Don’t go to ---------they will kill you in there
On a more positive note:
-----and he is cute!!!!
If you’re a doctor and don’t like the ratings: “The fact of the matter is that this site is only going to get more popular as time goes by, so the best way of dealing with it is to use it rather than try to fight it.” (In other words, get over it).
I’m a doctor. How do I get my name removed from your site? “The short answer is, you don’t.”
And if you’re thinking about legal action against the web site, don’t bother, say the owners (FAQ # 18).
Have a look. Are you rated?

There are also premed students looking for another perspective. Western doctors may generally be skeptical of the field, Kohn says, but she notices more of them are sending patients to classes in yoga and Qigong (posture and breathing exercises).
"You've got a new generation of doctors who've grown up with the idea that some self-practice, self-awareness is really helpful," she says.
Next thing you know, med schools will be adding it to their list of prerequisites, right alongside biology, organic chemistry, etc.

If conflicts of interest invalidate the development of guidelines perhaps we should question how the American College of Gastroenterology writes guidelines pertaining to endoscopy or whether the American College of Cardiology should write guidelines for coronary interventions. Such conflicts, though less tangible, are no less powerful than those involving drug company money. The journals tend to ignore them, as Detsky notes in this example: “A recent review article in the New England Journal of Medicine promoted positron-emission tomography (PET) scans for cancer assessment; of the 2 coauthors, 1 was a radiologist (who, I assume, reads PET scans). The article contained a statement that ‘No potential conflict of interest relevant to this article was reported.’ Really?”
Political agendas create powerful conflicts of interest as I have noted here, here and here. I first wrote about the “other” conflicts of interest over a year ago here.
In Detsky’s concluding paragraph he states “Although these other influences may be even more difficult to document and quantify than financial ties, they are no less important.”
Thanks to DB for pointing me to the editorial.
Rise of hospitalists and decline of primary care: true, true and unrelated in Wachter’s opinion. Not sure I agree.
How many hospitalists are needed? 30,000 to 50,000, perhaps, more than previously estimated.

The Center promotes this vast array of herbal products for everything from faulty immune systems to stress.
The Gables Natural Medicines Center and Day Spa is another NCCAM study site located in Mayville, New York, offering chelation and naturopathic medicine.
The Rhinebeck Health Center in Rhinebeck New York, another study site, advocates chelation therapy and a variety of other CAM modalities.

Guidelines, though useful, are imperfect. This can have unintended consequences when they are promulgated by agencies like IHI and JCAHO or become the focus of pay-for-performance initiatives. Even greater harm can result when they are hijacked by the trial lawyers and their hired guns under the rubric of “standard of care.”
Although the authors correctly point this out their criticism of the sepsis guidelines is misdirected and at times defies logic. Proper criticism of the guidelines should be based on the measuring stick of evidence. Portions of the Surviving Sepsis Guidelines indeed depart from high level evidence. The Perspective piece authors, however, don’t seem to care about evidence and disregard the fact that the only examples of the guidelines’ departure from evidence are unrelated to influence by Eli Lilly.
So let’s look at how each recommendation in the guidelines stacks up:
Early goal directed therapy----supported by high level evidence.
Diagnostic studies to ascertain source and microbiology---supported by low level evidence.*
Antibiotic therapy---supported by low level evidence.*
Source control---supported by low level evidence.*
Fluid therapy recommendations---supported by low level evidence.
Vasopressor recommendations---supported by low level evidence.
Inotropic agents---supported by low level evidence (high level evidence if used as part of early goal directed therapy).
Corticosteroids---conflicting evidence; use is controversial.
Activated protein C---supported by high level evidence.
Low tidal volumes for patients requiring mechanical ventilation---supported by high level evidence.
Sedation protocols and avoidance of neuromuscular blocking agents in mechanically ventilated patients---supported by high level evidence.
Intensive glycemic control---not supported.
Renal replacement therapy recommendations---supported by high level evidence.
Non-recommendation of bicarbonate therapy for most cases of hypoxic lactic acidosis---supported.
DVT prophylaxis---supported by high level evidence.
Stress ulcer prophylaxis---supported by high level evidence.
*Although diagnostic studies, antibiotic therapy and source control recommendations are based on “weak” evidence the guideline authors unequivocally recommend these measures. The ethical problems in demanding high level evidence for these modalities are obvious.
From the synopsis above it is readily apparent that any evidence based criticism of the Surviving Sepsis Guidelines would have to question intensive glucose control and the use of corticosteroids. The Perspective authors were conspicuously silent about these, the two weakest recommendations in the document. Why? Because they can’t blame it on the drug companies! Cheap, generic, plain ole insulin and hydrocortisone, the only non-evidence based drugs supported by the guidelines, are of no financial interest to the drug companies.
Gotta ask this question: is this ad hominem attack on the sepsis guidelines anything more than gratuitous bashing of the drug companies?

Homeopathy: Holmes, Hogwarts, and the Prince of Wales. This piece in the FASEB Journal isn’t just about homeopathy. It takes on many forms of pseudoscience currently promoted by NIH, NHS and U.S. medical schools. It concludes: Hogwarts is certainly on the move! If the trend persists, perhaps MIT or Cal Tech will march in step with the medical schools and offer prizes for integrative alchemy or alternative engineering.

St. Louis area hospitals, feeling the crunch, offer a picture of what can realistically be achieved by the most aggressive bed management conceivable, as reported in today’s Post Dispatch. It’s an impressive effort---arguably the best hospitals could be expected to make. These folks are organized, and they’re trying everything in the book, from more efficient room cleaning to electronic tracking systems. The results? Although diversion lessened it still occurs at a rate of one to two hours per day in spite of some patient boarding.
When there’s no room there’s no room, and there’s only so much you can do.

“The IOM is basically a government agency whose aim seems to be to find fault with and criticize health care professionals without having to find the means to properly fund their mandates. They make headlines and take the public's attention away from the real issues of healthcare economics. Our various professional organizations are afraid to refute their findings because we don't want to sound like we're whining. Yet we had better do so or all we're going to see is continued finger pointing and no real change.” I certainly agree with that. If the professional organizations won’t do it maybe the bloggers will!
As long as we’re picking on the IOM, NEJM recently reported on the IOM’s assessment of pay for performance. As we know, P4P is merely “playing for the test” and has little if any impact on real quality. Not to my surprise I found the IOM recommendations a little naïve. You can listen to the interview here or access a free transcript here.
The interview raises a few questions. They want to expand the P4P concept to reward not just quality, but also efficiency and “patient centered” care. Well, we already have a very powerful negative efficiency incentive----that hidden provider tax known as DRG. We also began a massive experiment in efficiency incentives almost a decade ago known as managed care.
And what is meant by “patient centered care”? It sounds great, but I thought all medical care was basically patient centered. It must mean something extra special----so what is it, exactly? Those folks at the IOM must be mighty smart if they can measure something as nebulous and subjective as patient centeredness. For phase two of their initiative they might consider measuring compassion, honesty, and empathy.
Although those are pretty lofty goals they’re going to start with the basics: reward providers “just for reporting data, at least initially.”

Today Grunt Doc offered a dissenting view and said (referring to DB, Kevin and myself): “The linked commenters in the first paragraph give a 'suck-it-up ED' subtext that rankles. We're doing that.” I guess I pushed the wrong button here, but no such subtext was intended. I was being critical of the IOM, not emergency departments. I have no doubt they’re doing the best they can.
He made this comment over at DB’s blog: “I think there’s a lot of arrogance in absolving the hospital of any responsibility to ease ED overcrowding. Overcrowding isn’t a result of ED inefficiencies, it’s a lack of hospital ownership of the patients admitted to the hospital through their own ED.” Wait a minute---nobody’s blaming the ER here. This isn’t “us against them.” The emergency department is part of the hospital. Their problems are the hospital’s problems, and vice versa. If the ER is overtaxed the entire hospital feels the strain due to extensive overlap and sharing of resources.
What’s Grunt Doc’s solution? Hallway beds. Fine. It seems to work at his institution. I’m not exactly sure what the hallway protocol entails, but I suppose it means that if all regular beds are occupied (hospital “full”) you put the patients where ever there’s physical space, initiate care and hold them there until a regular bed opens up. To me that’s a form of boarding, but you do what you have to do. There’s nothing written in stone in my mind that such boarding has to take place in the ER unless the patient needs cardiac monitoring.
But hallway boarding has its problems too. If the hospital has reached the capacity of its licensed beds (presumably the case if its wards are really full) might those hallway admissions run afoul of the law? In many cases it’s about more than licensed beds and physical space----it’s about staffing. That’s a patient safety issue. There’s plenty of evidence that higher patient to nurse ratios are associated with increased mortality. In this study, for example, 30 day mortality rose 7% for each patient added per nurse.
I’ll say it again. My whole point was directed at the IOM. They say hospitals wouldn’t have to divert or “board” if they’d just be more efficient. That is simplistic. Hospital administrators, physicians and case managers have been working their fannies off to make hospitals more efficient under draconian negative cost incentives (AKA DRGs) that have been in place for 23 years. That is not the answer to ER crowding.

Now the IOM will become the deserving target of the AHA. Given the abstracted and unrealistic ideas that seem to come with great regularity from the IOM, perhaps it is time government funds were spent elsewhere.
It seems wasteful to fund the production of so-called analysis that produces such wasteful and stupid results.
Wednesday, October 04, 2006
As I read the article everything seemed reasonable until I got to the discussion of ambulance diversion and emergency department boarding. Briefly, when no inpatient beds are available for hospital admission the emergency department may commence care of the patients and keep (“board”) them in the department until an inpatient bed becomes available. In extreme situations ambulances are diverted to other area hospitals. These practices have become quite common due to overcrowding. But now the IOM is recommending these practices cease, except in disaster conditions. That’s all well and good, but what’s the hospital to do when there’s no room in the inn? Dr. Kellermann writes that the IOM decrees “Hospitals can achieve this goal by adopting operations-management techniques and related strategies to enhance efficiency and improve patient flow.” Huh? Isn't that what hospitals have been struggling to do for their very survival ever since DRGs were enacted in 1983? This is supposed to solve the problem of ER overcrowding, suddenly? It strikes me as naïve. The full IOM report is here.
