Physician Burnout Is The Biggest Threat To Healthcare Reform

It was supposed to be delayed gratification.

After all, that’s the American way: work hard, put your nose to the grindstone, get good grades, be obsessively perfectionistic, then you’ll be rewarded if you just stay with it long enough. It’s the myth that perpetuated through medical school, residency and fellowship, and our poor residents, purposefully shielded from the workload they’re about to inherit, march on.

But then they graduate and find that just as the population is aging, chronic and infectious diseases are becoming more challenging, health advances and potential are exploding. Just then, we decide to launch a full scale attack on physicians and their patients with increased documentation requirements, call hours, larger geographic coverage of their specialties, reduced ancillary workforce, and shorter patient vists.

Physicians get it – burn out and dissatisfaction are higher now than ever before. This is probably the greatest real threat to the doctor-patient relationship and health care reform discussions don’t even put it this on the table.

At the same time that we expect our doctors to be devoted, available, enthusiastic, meticulous and at the top of their game with perfect “quality” and “perfect performance,” while simultaneously cutting their pay, increasing documentation reqirements and oversight, limiting independence, questioning their professional judgment, and extending their working hours. We must become more efficient!

Deal?

Political Meddling Forces Approval Of Dangerous Clinical Trial (TACT)

In one of the most unethical clinical trial debacles of our time, the NIH approved a research study (called the TACT Trial – Trial to Assess Chelation Therapy – a supposed treatment for arteriosclerosis) in which the treatment had no evidence for potential benefit, and clear evidence of potential harm – and even the risk of death. Amazingly, the researchers neglected to mention this risk in their informed consent document. The NIH awarded $30 million of our tax dollars to ~100 researchers to enroll 2000 patients in this risky study (ongoing from 2003-present). Even more astounding is the fact that several of the researchers have been disciplined for substandard practices by state medical boards; several have been involved in insurance fraud; at least 3 are convicted felons.

But wait, there’s more.

The treatment under investigation, IV injection of Na2EDTA, is specifically contraindicated for “generalized arteriosclerosis” by the FDA. There have been over 30 reported cases of accidental death caused by the administration of this drug – and prior to the TACT, 4 RCTs and several substudies of chelation for either CAD or PVD, involving 285 subjects, had been reported. None found chelation superior to placebo.

So, Why Was This Study Approved?

The NIH and the TACT principal investigator (PI) argued that there was a substantial demand for chelation, creating a “public health imperative” to perform a large trial as soon as possible. In reality, the number of people using the therapy was only a small fraction of what the PI reported.

It’s hard to know exactly what happened “behind the scenes” to pressure NIH to go forward with the study – however a few things are clear: 1) the National Heart, Lung, and Blood Institute (NHLBI) initially declined to approve the study based on lack of scientific merit 2) congressman Dan Burton and at least one of his staffers (Beth Clay) and a lobbyist (Bill Chatfield) worked tirelessly to get the study approved through a different institute – NCCAM 3) some of the evidence used to support the trial was falsified (The RFA cited several articles by Edward McDonagh, the chelationist who had previously admitted in a court of law to having falsified his data.) 4) The NIH Special Emphasis Panel that approved the TACT protocol included L. Terry Chappell, whom the protocol had named as a participant in the TACT.

All evidence seems to suggest that political meddling managed to trump science in this case – putting the lives of 2000 study subjects at risk, without any likely benefit to them or medicine.

A formal analysis of the sordid history and ethical violations of the TACT trial was published by the Medscape Journal of Medicine on May 13, 2008. Atwood et al. provide a rigorous, 9-part commentary with 326 references in review of the case. Congressman Burton’s staffer, Beth Clay, published what is essentially a character assassination of Dr. Atwood in response.

The NIH Writes TACT Investigators a Strongly Worded Letter

On May 27, 2009 the Office for Human Research Protections Committee sent a letter to the investigators of TACT, stating that they found, “multiple instances of substandard practices, insurance fraud, and felony activity on the part of the investigators.” The letter describes a list of irregularities and recommends various changes to the research protocol.

It is almost unheard of for a letter from the NIH to state that research study investigators are guilty of fraud and felony activity – but what I don’t understand is why they haven’t shut down the study. Perhaps this is their first step towards that goal? Let’s hope so.

Conclusion

The TACT trial has subjected 2000 unwary subjects and $30 million of public money to an unethical trial of a dubious treatment that, had it been accurately represented and judged by the usual criteria, would certainly have been disqualified. Political meddling in health and medical affairs is dangerous business, and must be opposed as strongly as possible. Congressmen like Tom Harkin and Dan Burton should not be allowed to push their political agendas and requests for publicly funded pseudoscience on the NIH. I can only hope that the new NIH director will have the courage to fend off demands for unethical trials from political appointees.

Recent Heart Attack? Consider Cardiac Rehab!

Cardiac rehabilitation, or guided exercise under direction of a physical therapist, is a valuable yet underutilized therapy for patients suffering a heart attack. Importantly, in those patients with ongoing risk factors related to obesity and insulin resistance/diabetes, aggressive cardiac rehab was recently shown to be especially effective.

Specifically, two groups of patients were enrolled in high intesity (5-7 days weekly of 45-60 minutes exercise) versus standard (3 days weekly of 25-40 minutes exercise).

High intensity patients lost more than twice as much weight over 5 months as standard patients (18 pounds vs. 8 pounds and had significantly greater reductions in 2 major cardiac risk factors — waist circumference and insulin resistance. At 1 year, both groups had gained a couple of pounds over 5-month weights, but total body-fat percentages in the aggressive group remained significantly lower than initial readings. Other cardiac risk factors changed too – including decreased insulin resistance, increased HDL (good) cholesterol, and decreased measures of insulin, triglycerides, blood pressure, plasminogen activator inhibitor-1, and the ratio of total to HDL (good) cholesterol.

Overall then, patients who took advantage of their motivation after heart attack to aggressively address exercise goals reduced potential risk factors and set the tone for a healthier life. If you have been a heart attack sufferer, ask your doctor about cardiac rehab. If you are not a heart attack sufferer but have risks, ask your doctor about trying a program like this on your own.

Questions and comments welcome as always!

Why Implantable Defibrillators Are Still So Expensive

Thanks to Dr. Wes for pointing us to a remarkable video of a 20-year old Belgian soccer player having his life saved by an implantable cardiac defibrillator (ICD). DrRich hopes you will view it.

As it happens, DrRich will be traveling to Europe imminently at the invitation of Dr. Pedro Brugada, whom some call Belgium’s King of Electrophysiology, and for whom the Brugada Syndrome is namesake. (DrRich is deeply honored to be one of the “masters” at Dr. Brugada’s “Meet the Masters” event, which gives him the opportunity to spend two days with a hand-picked group of top European and American electrophysiology fellows. DrRich will undoubtedly learn a lot from them, and will try very hard not to ruin these fine young physicians before they’ve even started out.) In any case, one must suspect that Dr. Brugada (being, after all, Belgium’s King of EP) must have been somehow responsible for placing the ICD in this young soccer player.

DrRich will be sure to ask him how that young man managed to receive an ICD. Because most high-risk patients, in the U.S. and elsewhere, have to do without.

Despite the fact that ICDs are dramatically effective and dramatically life-saving in people who have dangerous cardiac arrhythmias (please do watch the video to see the drama for yourself), they are still used in only a tiny fraction of the identifiable patients who are at risk for sudden cardiac death. Consequently, in the United States alone, almost 1,000 patients each day die suddenly from cardiac arrhythmias who could have been saved by an ICD.

DrRich has written before about the covert rationing of ICDs, which is done so openly that one is tempted to drop the modifier “covert,” and has even written about how a former government official has admitted that he had no choice but to juggle the statistics of a randomized clinical trial (i.e., to bastardize the science) in order to avoid having to pay for ICD therapy in broader categories of patients.  That’s old news, and there’s no reason to beat it to death again here.

Instead, DrRich would like to explore another question – Why are ICDs still so damned expensive?

Having worked closely with ICD manufacturers since the early 1980s (which, DrRich knows, makes him a very bad person), he perhaps more than most appreciates the engineering magic that has gone into making and improving these devices over the years. It is a truly remarkable thing that one can build a tiny implantable device that a) houses a computer that runs an extraordinarily sophisticated heart rhythm analyzer that, from beat to beat, accurately diagnoses the heart rhythm in real time; b) can deliver a tiny electrical pacing impulse to the proper cardiac chamber at the proper time, from beat to beat, to coordinate and optimize cardiac function; c) then, if a fatal arrhythmia develops, to deliver a very big shock to the heart within 10 – 15 seconds, to restore the rhythm to normal (please do see the video); d) wirelessly communicate via the Internet to tell the doctor (and anyone else who needs to know) its own condition and the condition of the patient; e) all the while surviving in a hostile, high-temperature, salt-water environment (i.e., the human body), for 5- 7 years, without (for the most part) corroding, leaking, rusting, blowing up, or otherwise malfunctioning.

Try to get your iphone to do that.

At this point, most of DrRich’s regular readers are likely expecting him to say: No wonder these beasts cost $15,000 to $25,000 apiece.  Just look at the sophisticated technology that is built into them!

And it is indeed true that over the past 27 years, hundreds of millions of dollars have been invested in making ICDs smaller, more reliable, longer lasting and safer. It is also true that the companies that make these devices ought to be fairly rewarded for their efforts in this regard. And for many years (DrRich estimates that the “right” number of years was about 18) the high cost of ICDs was easily justifiable, given the steady, remarkable, important and meaningful improvements in technology that took place during that time, improvements that were being funded by the cost of the devices.

But DrRich argues that by the turn of the millenium, ICD technology had become largely mature, and that since that time improvements (while still happening) have been merely incremental. “Gingerbread” might be too strong a term, but nonetheless that’s the term that pops into DrRich’s mind. The fact is that by the year 2000, all ICD manufacturers were building reliable, safe devices that were really good at preventing sudden death, and improvements since then have not altered (or materially improved on) that fact.

Here’s a truth that ICD manufacturers would not like us to know: It only costs them a couple of thousand dollars to build an ICD. DrRich does not know the precise dollar amount (very few people even in ICD companies know these precise amounts) but based on his experience he cannot see how it could be much more than about $3000 per unit.  Now, lest you think that the roughly $22,000 difference between the cost to manufacture and selling price is pure profit, it’s not. ICD companies continue incurring expenses as long as an ICD remains in service. These “lifetime” expenditures include monitoring of device function; maintaining expensive, rigorous quality and reliability processes; and backing up every implanted device with a large force of highly-trained and expensive field clinical engineers who are available to electrophysiologists 24/7, anywhere and everywhere, for “troubleshooting” and even for routine follow-up. All this “extra” stuff must be fully accounted for in the initial price of the device.

Still, ICD manufacturers make a very, very nice margin on every device they sell. Few businesses in the world enjoy this kind of price margin.

With all that “room” to play with, one might think market forces would by now have brought the price down for a mature technology like this, especially since over the past few years the growth of the ICD market has flattened, and ICD companies now must compete with each other for more market share if they want to grow their businesses.

But classic market forces usually do not work in healthcare, and that is especially true when it comes to ICDs.

It all begins with Medicare reimbursement, which sets the price for ICDs, and consequently the cost of ICDs is likely to remain at $15,000 – $25,000 forever.

Now, to be sure, the government does not directly determine what companies get paid for ICDs. Rather, they indirectly determine the price by deciding what hospitals and physicians will be reimbursed for implanting ICDs. Those reimbursement rates apparently vary substantially from region to region and hospital to hospital (who knows how the government determines these things?), and the rates are not publicly available to DrRich’s knowledge. But ICD manufacturers, at worst, can impute the reimbursement rates by figuring out the top price specific hospitals are willing to pay for ICDs (hence the range in prices).

Having determined the top price they can possibly get paid for ICDs, the only logical strategy for manufacturers is to figure out how they can always get paid that top price for every device they sell. They do this by making ICDs specifically aimed at keeping the decision makers happy. And the decision makers, by and large, are the electrophysiologists.

Electrophysiologists decide who gets ICDs, and they decide which ICDs to implant. So, to keep prices at the highest possible level, ICD companies must cater to the wants and needs of electrophysiologists (their true customers), and so must  produce a steady stream of new, improved ICDs whose novel features are requested by these very high-end, high-maintenance physicians.

Electrophysiologists have a clear agenda in this regard. Their “demands” on ICD companies, expressed in rigorously conducted marketing surveys and focus groups, inexorably lead to ever more complex devices. This complexity helps electrophysiologists (a small community whose growth is tightly controlled) to maintain a professional stranglehold over the implantation and management of ICDs.

It’s a matter of turf protection.

Since ICDs are already exceedingly complex devices, and grow more complex with each succeeding generation, then “obviously” one must be a high-end specialist like an electrophysiologist to understand and manage all their nuances. (In real life, ICDs have become so complex that not even a majority of electrophysiologists can keep up with them any more, thus necessitating armies of “clinical engineers” in the employ of ICD companies who can do troubleshooting in the field.)

All the ICD manufacturer needs (and wants) to know is: what gingerbread do I need to add to my next generation of ICDs to make them even more stupefyingly complex, so as to maintain the loyalty of my electrophysiologist customers? If they can answer this question manufacturers will continue to be paid top dollar for their product (again, as determined by regional reimbursement rates set by the government).

And this is why, despite the fact that ICD technology has been fully mature (says DrRich) for most of a decade now, which in a functional market would cause the price to plummet, the cost of ICDs remains so high. Whatever has developed in the complex interplay between ICD manufacturers, electrophysiologists, hospitals and the government, it’s not a functional market.

Among other things, this dysfunctional economic model (if that’s what it is) utterly precludes ICDs ever becoming available to a large proportion of individuals whose lives could be saved by them. They’re simply too expensive and complex for widespread usage.

Covert rationing, of course, thrives on opacity, obfuscation, confusion, inefficiency and complexity, and the convoluted ICD “business model” provides many, many avenues for covert rationing. So while the price remains high, relatively few ICDs actually end up being implanted (compared to the number of patients who have clear, FDA-approved indications for ICDs). In fact, the growth curve for ICD implantation has been successfully flattened for almost five years now (despite projections earlier this decade for 20% annual growth for years and years) – and it is likely to stay flat.

If we were to have a system of fully transparent, open rationing, then the ICD business model would rapidly be seen as the travesty of confusion that it is. Furthermore, a system of open rationing would quickly goad ICD manufacturers away from catering to the turf-based requests for more complexity by electrophysiologists. They would quickly develop ICDs that are simple, reliable, effective, easy to implant, long-lasting and cheap, and which could be safely implanted and managed by non-electrophysiologists.

The technology to do that exists today.

This is an example, DrRich believes, where open rationing would ultimately lead to more usage of a life-saving technology, by driving industry to put their development efforts into reducing the cost and increasing the simplicity and reliability of their products, and thus making them more cost effective, rather than striving to make them more attractive to high-end-physician decision makers. If they did this, then videos like the one Dr. Wes has shown us would no longer merit mention on blogs or on any other form of media, as ICD rescues would become very common.

DrRich has been telling all this to ICD companies for many years to no measurable effect. Of course, it has been well documented that DrRich is more than willing to tell his clients stuff they may not particularly want to hear. (It’s truly amazing that he can still make a living as a consultant.)

In any case, here’s DrRich’s investment advice for this week:  The growth of the ICD market is destined to remain flat as long as  high-priced, gingerbread-laden ICDs that only an electrophysiologist can love remain the norm.  Avoid companies whose growth depends on these devices. On the other hand, the ICD market is ripe for a major disruption, if one of these outfits ever figures it out.

DrRich will now fade into quietude here for a week or so, as he entertains those nice people in Europe with his crazy ideas about healthcare.

Stroke During Coronary Bypass Surgery – an Article Review

My mother died last Tuesday.  She had her coronary bypass surgery just one week before that day.  It was during her CABG that she had her strokes.  Yes, strokes, plural.  She was one of those 1.5% who suffer macroemboli cerebral strokes during coronary bypass surgery.

I went looking for information on it earlier this week.  I went through my training without ever seeing this complication.  Like everyone, I never thought my family would be the one.  I think it is better to go to surgery, NOT thinking you will be the “statistic” as far as complications go.  Anyone having surgery, SHOULD go into it feeling hopeful and thinking everything will go perfectly.

The article referenced below is a good review of this complication – stroke during coronary bypass surgery. The study is a retrospective review of 6682 consecutive coronary bypass patients who only had the CABG procedure and not other simultaneous procedures, such as carotid endarterectomy.

They list the possible sources of the emboli as the ascending aorta, carotid arteries, intracerebral arteries, or intracardiac cavities.  They state that they believe the most likely source is the ascending aorta, for the following reasons:

First, the ascending aorta is the site of surgical manipulations during CABG, whereas mechanical contact is not made with the other potential sources of emboli.  Embolization of atherosclerotic debris is most likely to occur during aortic  cannulation/decannulation, cross-clamp application/removal, and construction of proximal anastomoses. However, embolization of atherosclerotic debris may also occur when the aorta is not being surgically manipulated, due to the ‘sandblast’ effect of CPB.

Second, the majority of our independent predictors of stroke – elderly age, left ventricular dysfunction, previous stroke/TIA, diabetes, and peripheral vascular disease – are strongly associated with atherosclerosis of the ascending aorta.

Third, our chart review suggested that the most common probable cause of stroke was atherosclerotic emboli from the ascending aorta. Palpable lesions in the ascending aorta were noted in a large proportion of stroke patients.

The fourth reason we believe the ascending aorta is the likely source of macroemboli is because of ancillary autopsy data. …….

Note the second reason given above – the independent predictors of stroke.  My mother was over 74 yr so fell into the elderly age risk factor group.  She was also a type 2 diabetic.  She was noted to have a small abdominal aneurysm and some renal artery stenosis on the angiogram (an accidental pickup).  So she had three of the four independent risk factors.
