Reduce, Destroy, Demoralize, or Why a Single-Party Payer is the Only Sensible Option

The following paper was published two weeks ago in the healthcare policy journal Health Affairs (abstract and author affiliations provided):

Should Health Care Come With A Warranty?

Many goods and services come with warranties; should health care? Analysis of one payment model shows promise and challenges.

by Francois de Brantes, Guy D’Andrea, and Meredith B. Rosenthal

ABSTRACT: How health care providers get paid has implications for the delivery of care and cost control; the topic is especially important during an economic downturn with persistent growth in health spending. Adding “warranties” to care is an innovation that transfers risk to providers, because payment includes allowances for defects. How do such warranties affect patient care and bottom lines? We examine a proposed payment model to illustrate the role of warranties in health care and their potential impact on providers’ behavior and profitability. We conclude that warranties could motivate providers to improve quality and could increase their profit margins. [Health Affairs 28, no. 4 (2009): w678–w687 (published online 16 June 2009; 10.1377/hlthaff.28.4.w678)]

This paper, as you can imagine, has garnered some attention. The New York Times columnist Pauline Chen, MD, interviewed the lead author of the paper for an article in the June 25 issue of the NYT, and Tara Parker-Pope opened it up for an online discussion on her blog.

This discussion has been quite contentious, as Tara gets read by a lot of physicians and other healthcare providers. Of the 40 or so posts, not surprisingly, not one welcomed the idea. There were many emotional and sometimes bilious comments mostly around how patients’ non-compliance might influence individual practitioners’ reimbursements under this system. Many of the comments reflected the sense of disempowerment so prevalent among physicians today.

But the devil is usually in the details. So, I read with great interest the actual paper by de Brantes and colleagues. After all, the authors themselves are no slouches, and between them have decades of academic and real-world experience in healthcare policy. The authors propose separating what they refer to as “probability risks”, or those risks inherent in the patient and his/her circumstances, from “technical risks”, or those risks related to what they call “care production”. While the former are to be carried by the insurer, the latter, they suggest, are to be borne by the provider. To be fair, they do not call for zero compensation for the preventable acquired conditions (PACs, or those conditions acquired as the result of inappropriate process of care, such as preventable hospitalizations for a chronic condition). In fact, they propose mining the vast repositories of data that are already in existence to arrive at the middle-of-the-road estimates for their associated costs of care, allowing for a 50% frequency of the current rate of PACs. As an example, if the national rate of PACs is 12%, this payment system will cover a 6% frequency of PACs. This way, the authors argue, the providers are still covered for some baseline occurrence of PACs, and at the same time are rewarded for driving them down as much as possible. The result of this is that those providers who have very low PAC rates can make a substantial profit even under this system. Elegant, no?

Unfortunately, as someone who deals with data day in and day out, I am only too aware that reality is much messier than theory. The authors’ intentions are certainly good, and the road to Hades is paved with good intentions. This is a great system for physicians who take care of patients who are not too sick and who have the financial and cognitive means and the will to follow their recommendations. On the other hand, what happens to a provider who takes care of an inner city working poor population, who in the best of economic times end up splitting their blood pressure pills and cannot afford to keep to a heart healthy life style, and thus put themselves at risk for preventable hospitalizations? And what is the effect of the current profound economic crisis on these already marginally “compliant” patients? And realize that, since all healthcare is local, these patients are not conveniently and evenly distributed across all providers in the US. So, the very phenomenon that everyone is trying to avoid, patient profiling (cherry-picking only the healthiest and most compliant patients), is one of the very real potential unintended consequences of this proposed payment reform.

This proposed system takes away from both physicians and patients in other ways too. It takes all choice away from the patient and assumes that we, lemming-like, will follow all recommendations of our physicians. I may have already convinced you that one person’s evidence of benefit is another person’s evidence of uselessness. Since the authors suggest basing judgment of procedural correctness on either best evidence where available or expert opinion (and don’t even get me started on “expert opinion”!), there will not likely be much room for individual judgment, either for a physician or a patient.

But I want to bring up another, much more insidious consequence of this (and other) pay-for-performance scheme. Psychologist Barry Schwartz maintains that reducing all motivation to external rewards demoralizes people in two ways: in the conventional sense of taking away hope and enthusiasm, and also by eliminating morals as the driver of our actions. Let’s face it, it is downright absurd to suggest that we spend 4 years in medical school and put ourselves through additional 3-10 years of grueling training on top of that (while making less money than a receptionist) in order to get rich. The pursuit of reimbursement is for most MDs the direct result of this demoralization.

And this brings me to my conclusion: the only sensible response to this crisis is to create a single-party payer system and to salary all healthcare providers. With a salary, provided that it adequately reflects one’s investment of time and energy, there is no incentive to provide unnecessary and costly care, and physicians can concentrate on providing good care instead of drowning in bureaucratic process. Some surveys suggest that nearly ¾ of all MDs are for single-party payer. What are the rest of us missing? Tell Congress to stop throwing your tax dollars away on stupid experiments that simply rearrange the deck chairs on the Titanic: the market model of healthcare has already failed us.

Patients' rights

I went for my routine physical last week, not that I believe in routine physicals. But I bit the bullet and went, largely to appease those around me who believe in their usefulness, and to make sure that my doctor still remembers me. After a thorough clinical examination and a lovely chat, my doctor asked me what labs I might be interested in checking. Knowing the US Preventive Services Task Force's recommendations for screening a patient like me, I opted to get no lab studies. I further informed my physician that my reading of the literature has convinced me that, given my risk factor profile, I do not wish to have any more screening mammograms until the age of 50. I also had to apologize to her, knowing that the pay-for-performance rules of my insurer will withhold a certain amount of her quality care bonus payment for not obtaining annual screening mammography.

I tell this story because it illustrates a couple of important points. First, since I am an uber-informed consumer, I have the wherewithal to make educated decisions at every step of my encounter with the healthcare system. An additional societal benefit is that, as a responsible consumer, I can help drive down costs by personally promoting efficiency. Of course, it took not only 10 years of post-graduate schooling and training, but also an additional decade of researching to develop the skill to navigate this complex and convoluted environment. What follows is a realization that the politicians' call for healthcare consumer empowerment is more political posturing than a credible policy directive. As a very competent physician friend of mine pointed out to me, you cannot become a medical expert on Google -- the information and decisions are esoteric and specialized to the point where even physicians are not always aware of their intricacies. Not too comforting, hey?

So, what are the choices? A peer review system is something to advocate for, but more on this later. I guess the inevitable conclusion is that, at least to a degree, patients have to allow for substituted judgment by their healthcare providers. And this brings me to my second point. The practice of medicine has become defensive. What I mean by this is that every patient to a certain extent represents a potential law suit. And this is certainly a direct result of egregious misuse of our tort system, intended to be an equalizing instrument within our society. I know this is a worn justification for runaway healthcare costs and dysfunctional physician behavior, but it is not entirely imagined. Our culture deplores risk, and we as consumers have been conditioned by clever marketing that to protect ourselves from such risks, real or imagined, as burglaries and kidnappings, all it takes is more spending on the latest gadgets. We have also adopted this attitude in the way we think about healthcare: if a mammogram is good at detecting an early cancer, an MRI or anything digital must be even better, right? We worship at the shrine of technology and use our children's future as the sacrificial lamb to bargain for a disease-free passage into old age. And so, if a physician uses her judgment to recommend against a mammogram, and, against all known odds, a cancer is subsequently discovered, a law suit usually results, even if the decision was not due to negligence, but rather because of understanding the patient in the context of what is known about her risk.

People who know me well, including my students, know that I love to think in threes. So, in that spirit I am going to make a third point. This is something that eludes not only the lay public, but also government agencies, insurers and practitioners alike. I am of course talking of the risks and consequences of a false positive result. As an example, I am talking about getting a "routine" urinalysis in a healthy woman, discovering what we call an asymptomatic bacteruria (bacteria in the urine not causing an infection), treating her with an antibiotic, which in turn results in a serious intestinal infection with the bacterium Clostridium difficile requiring a surgery to remove her colon in order to save her life. This is but a small illustration of how doing more, although well-intentioned, can derail not just a sensible way of practicing medicine, but indeed a person's entire life. A similar scenario can be imagined with, yes, you guessed it, mammography: a lesion detected, resulting in an invasive procedure, resulting in an infection followed by multiple complications and further interventions, while the lesion proves to be entirely benign. And then, of course, the same insurance company that may be dictating a screening mammogram as a quality measure to determine the physician's reimbursement, subjects the said patient to a rescission (withdrawal of insurance coverage due to a pre-existing condition).

So, as with everything else in life, the adage "everything in moderation" applies to your dose of healthcare. It is your right as a patient!

Physicians, healthcare costs and getting beyond the blame game

Well, unpopular opinions are just that -- unpopular. But you have to start somewhere.

I wrote the paper posted below over the last couple of weeks knowing full well that is would get rejected by medical journals out of hand, and it has. So, I feel fortunate to live in this technologically advanced age that allows me the opportunity to publish it anyway! Here goes:

An article by Atul Gawande, MD, in a recent issue of The New Yorker magazine caught my eye. In it he was describing his journey through several Texas towns in search of an explanation for the long-appreciated regional variations in Medicare expenditures1. He was specifically interested in why it was that annual per capita Medicare costs in the town of McAllen in Hidalgo County were over $15,000, while those in El Paso county, just 800 miles away, were $7,504. His quest compelled him to speak to many physicians and administrators, as well as to understand regional health statistics. Going through many potential explanations for this disparity, and rejecting each in turn after subjecting it to an intellectually rigorous evaluation, he concluded that in large part these disparities are driven by local healthcare providers’ attitudes towards the practice of medicine. That is, he discovered an inverse relationship between costs and whether the culture in the medical community was more concerned with the patients’ needs rather than with maximizing revenue. With this stroke of his pen, Dr. Gawande opened wide a window on a dirty little secret: the responsibility of individual practitioners in the escalating costs of healthcare in America.

It may be easy to dismiss this idea as an aberration, a few bad apples spoiling everyone’s reputation. It is more difficult to do this in light of the findings by the Dartmouth group, who for years have been reporting vast differences in per capita Medicare spending in different parts of the US, spending that is not commensurate either with worse underlying population health or with better health outcomes. To be sure, Gawande’s theory is not a surprise to anyone who has experienced private practice and has come in contact with the full spectrum of physicians – from those committed to doing what is in the best interest of the patient to ones committed to maximizing their profit. It is neither cynical nor far-fetched to posit that the increasing demands and diminishing returns, both financial and in professional satisfaction, in the race to commodify medicine may drive doctors to prioritize their bottom line above patient care, either implicitly or explicitly. Why not, in a system that financially rewards doing more rather than doing better?

It also becomes more difficult to write off this behavior as an exception when viewing it in the context of the social and political history of our profession. American medicine developed through a series of power struggles and coups worthy of a pulp novel. Early physicians had little political muscle and even less education to distinguish themselves from traditional healers and outright quacks. Yet through formal organizing into exclusive medical societies and by eventually establishing strict licensing rules, they were able to seize enough power to increase their market share of healthcare delivery. During the Industrial Revolution, a heightened emphasis on medical education, better hygiene in hospitals, development of transportation and the change from home- to factory-based business model resulted in moving most of healthcare provision from the home into the office and the hospital. In this way doctors were able to increase their incomes by increasing their daily throughput dramatically: instead of traveling far and wide to visit the ailing, they could see them in the office, an indisputable improvement in efficiency. Over the next century many battles over healthcare financing and access would ensue and persist until today, in which, to use the words of Princeton University Professor Paul Starr from his Pulitzer Prize-winning book The Social Transformation of American Medicine, the “search for efficiency conflicted with the doctors’ defense of their income and autonomy”2.

The conclusion is inevitable: physicians too have had a part in driving up costs of care in the US. While we are willing to admit to our charming penchant for ignoring evidence, and to some misguided inclination among few in our ranks to lie by omission about their support dollars, we rarely see this admission of fiscal guilt in our scholarly journals. What we do see is a massive effort to deflect attention away from our bad behavior to the ills perpetrated by others. The inevitable villains in this formula are the manufacturers of drugs and devices, as well as insurance companies and lawyers. Since I have done a lot of work over the years in partnership with manufacturers, I am well aware of the diverse motivations among their employees. Much like the attitudes of physicians, the ethos within pharmaceutical and device companies ranges from dogged dedication to the well being of the patient to unbridled profit motive. As for the insurance industry, I have traditionally been eager to expose their dirty underbelly. It is in this spirit that I read the recent report from the WellPoint Institute indicating that only 3 cents of every health insurance dollar represents profit3. It is of interest that an average net profit margin for consumer goods (that is all the stuff we as consumers purchase) is 6.57%4, putting the insurance company profits well below this number. At first, I was tempted to discard these data as industry propaganda. But upon dutifully reading the report and then reflecting on it in light of Dr. Gawande’s article, I began to overcome my anti-insurer bias in favor of starting the difficult task of recognition through self-reflection.

What is the over-arching point here? Physicians are human. To admit this does not in any way take away from the selfless dedication of large numbers of doctors to their patients, even, as we were grimly reminded recently by the cold-blooded murder of Dr. Tiller, at the expense of their lives. No one group is innocent; all parties in our healthcare quagmire have been responsible in some way for getting us here. To blame only someone other than self is counterproductive and disingenuous, as is focusing singularly and selfishly on interests of one’s own stakeholder group. We owe it to our patients and the society to come together, all of us, armed with the emotional maturity and political will to listen to each other’s concerns and to promote a culture of cooperation. The conversation, likely to take place in shades of gray, reflecting the topic’s complexity, has to start today and continue until solutions are found whose goal is not merely to appease every participant, but to provide a comprehensive roadmap to developing what may deserve to be called the greatest healthcare system in the world.

Less is more

So, you noticed that on several occasions I said that health does not generate revenue, disease does. Let us examine this statement a little more closely and see if it is true.

There are two traditional ways to structure a proof:
1). By citing examples, and 
2). By disproving the opposite
While in statistics and epidemiology we favor the second, I will step away from this in favor of the first method and will explore a relevant example. Since I am still reading Devra Davis's book (see my recent post), the example will come from the world of cancer.

Let's take breast cancer, for example. Your counter-argument to my statement is probably that mammography is the perfect example of how health promotion can turn into a viable business model. OK, let's examine our assumptions. The central assumption here is that mammography is indeed a health promoting technology. What we hear is that early detection saves lives, so we encourage all women at around age 40 years to begin with annual screenings. And look, the proof is in the pudding: survival with breast cancer has improved dramatically over the last 2 decades. But is this really cause and effect? Most data do not support the idea that mammography decreases cancer mortality. Indeed, among younger pre-menopausal women the usefulness of mammography has been questioned by several reputable groups. Younger women's breasts are dense and are prone to high false positive rates of mammographic findings. These then have to be followed up with additional tests, such as an ultrasound or even an MRI with contrast (costly interventions beget further even costlier ones). On occasion, the only way to rule out a malignancy is through surgical excision -- you have to agree this is a very high price to pay for a diagnosis of a benign breast lesion! Sometimes, however, a very early cancer will be diagnosed and excised,which is potentially life-saving, right? Well, this is not so clear either, as scientists are beginning to conclude that many of the very early ductal carcinomas in situ, or DCIS, are probably subject to the woman's own immune extermination and do not develop into life-threatening aggressive disease. So, at least there is no lasting harm from screening mammography beyond the short-term physical and emotional ordeal, so the benefit still outweighs the risk, right? Not so fast. Since mammography exposes a woman to a dose of radiation, albeit small, there is reason to question whether mammography itself may be cancer-causing in some individuals.

I do not want to sound cavalier and suggest that we all quit getting our annual mammograms. What I am suggesting is that each of us take the time to learn about the data and discuss them cogently with our healthcare providers in order to make the most sensible individual decisions. At the same time, we need to acknowledge that there is no free lunch. What I mean by that is that early identification (typically through the utilization of costly technological interventions) does not equal prevention (typically through identification and systematic avoidance of potentially causative exposures). Even the language implies the economic consequences of each -- revenue generation through utilization and revenue loss through avoidance. 

Many of the same concepts can be applied to structuring arguments in other areas of healthcare interventions, but I will not belabor this point now. The bottom line is that the less we think we need, and this includes cars, television sets, soda, the less potentially detrimental disease-causing environmental exposures we may subject ourselves to. But, of course, at the same time, the worse our 401Ks will perform. So, once again, the choice is ours -- health or wealth?

Is obesity the next cancer?

I am reading a very thought-provoking book right now: The Secret History of the War on Cancer by Devra Davis. In this book Dr. Davis lays out a very detailed story of how much of the knowledge on cancer risks related to environmental factors, gathered as long ago as the 1930s, was suppressed in the US mostly due to diligent efforts of chemical and tobacco companies. In fact, today, the National Institutes of Health spends roughly $170 million on lung cancer research alone. Of incidental interest is the fact that despite being the most common cause of cancer deaths in the US, lung cancer's allocation was less than 1/4 of the revenue going to breast cancer in the same year ($726 million). The proportion of these numbers that goes to prevention research is very difficult to find. However, when one is familiar with the scientific literature in this field, it becomes self-evident that the vast majority of the developing interventions is in the treatment arena. And why is this? Well the answers are both complex and obvious -- I go back to my recent statement that health does not generate dollars, disease does, and for so many stakeholders in this instance.

But I did not really want to focus on cancer -- I do, however, recommend that you read Davis's book to learn more, if interested. I wanted to talk about obesity instead. I recently came upon this statement from the very reputable Cochrane Collaboration, an academic group that synthesizes the vast expanses of medical literature into manageable reports: "The current evidence suggests that many diet and exercise interventions to prevent obesity in children are not effective in preventing weight gain, but can be effective in promoting a healthy diet and increased physical activity levels." (http://www.cochrane.org/reviews/en/ab001871.html) Really? Has human physiology changed that much over the last few decades that we are now refractory to the weight control effects of eating well and having sensible levels of activity? On the other hand, the same group tells us that bariatric surgery "results in greater weight loss than conventional treatment in moderate (body mass index greater than 30) as well as severe obesity. Reductions in comorbidities, such as diabetes and hypertension, also occur. Improvements in health-related quality of life occurred after two years, but effects at ten years are less clear. (http://www.mrw.interscience.wiley.com/cochrane/clsysrev/articles/CD003641/). Hmm... interesting. So, diet and exercise do not work, while bariatric surgery does well at controlling obesity and its consequences. Sound familiar? 

Interestingly, research suggests that high fructose corn syrup, the generic sweetener du jour that children and adults guzzle by the pound daily in their sodas, juices, candy and cookies, is sweeter than regular sugar and thus more palatable to the human animal, resulting in higher amounts consumed. Could this be one of the causes of our obesity epidemic? Is bariatric surgery with its expense and risks really the most obvious (not to mention cost-effective) answer? Well, how about studies that link television watching among our children to unhealthy eating habits and lack of exercise, thus resulting in a climb of the BMI among the youngest members of our society? Bariatric surgery again?

So why, you ask, was the evidence for cancer-causing chemicals kept secret for decades, and how is it relevant to the obesity problem? As you can imagine, many chemical manufacturers would have had substantial economic losses had this evidence come to light sooner. Even today, because studies linking exposure to certain substances with development of cancer are epidemiologic in nature, and thus cannot prove causality beyond the shadow of a doubt, evidence is conveniently twisted and discarded by the clever legal structure created around this type of litigation: a strong suggestion of causality is not enough to inject caution into the use of these compounds. In a similar vein, we do not want to hear that it is the way we eat and live that has created the obscenely pervasive obesity epidemic. Why should we, when we have pills and surgery to combat it? After all, this approach does not take the profit away from the manufacturers of high fructose corn syrup (also benefitting from our tax dollars dumped as subsidies into growing corn monocultures), and in fact it creates a market for new instrumentation and procedures for the vast healthcare industry. Prevention? "That is not economically feasible." Let's cut the crap! Prevention takes political will, which we do not seem to have at the moment, as we are all too busy having our cake and eating it too, particularly since life is sweeter with high fructose corn syrup.

The business of news

When I was growing up in the 1970s (yes, in fact it was last century, thank you very much), news was different. And I do not think that this is just the everything-was-better-in-my-day nostalgia. News was about news. News was not sexy (heck, newspeople were not sexy!). What has happened to the news? Well, if you have read Robert Reich's Supercapitalism, the answer is obvious to you: competition. Interestingly, economic theories suggest that competition is good for the consumer -- it drives quality up and prices down. That may be true for toilet paper (although even here I am not sure this idea has held water), but it has not panned out for such consumables as news and healthcare. Instead, what happens is that all of the market moves in the same direction, applying the same strategies and tactics to maximizing value to their investors. By definition, a high bottom line comes from only two sources: low expenditures or high returns, and preferably both. Since commercial news channels are supported through advertising, their market share of our eye ball and ear time are critical to investor value. Thus, the slippery slope to the lowest common denominator (here we go again with the denominators). 

With the advent of constant news the competition for market share became far stiffer than we could have ever imagined in the 1970s. In order to distinguish one Constant Chatter Channel from another, marketing ideas had to be applied; and they were. The anchors are now for the most part younger, prettier and more friendly-appearing than in the days of yore. They keep us glued to the screens with a constant barrage of headlines and sound bites designed to tantalize, terrify and titillate, and ultimately sell more products: hospital services, safer (gas guzzling) cars, home alarm systems, etc., to keep us wrapped in a cocoon of comfort and ignorance.

It is interesting to think of our healthcare system in this context as well. A mammoth enterprise generating staggering returns for many involved (this includes some physicians, academic researchers, manufacturers, insurers, and, yes, investors), it has not promoted health, but disease maintenance. Why is this? Well the simple answer is that health does not generate income, disease does. And furthermore, think of the economic consequences of cleaning up such promoters of disease as tobacco, certain forms of pollution, as well as the way we produce food... In fact, think of the financial and thus political muscle behind these industries, a Goliath that can easily stamp out any grass-roots efforts to set disease prevention agenda. Add into the mix the at once frightened and phlegmatic populace expecting to be entertained by the news, and how we got here becomes obvious. The less obvious issue is how we move out of this morass of mis-information. 

As I have already mentioned, I do not believe that premeditated evil is a common human practice. In fact, I have to conclude that our slide into the current situation is a result of chaos. Further, it is a result of the unopposed stakeholders with too much to lose and thus too many personal agendas. The healthcare system has been like a symphony orchestra without a conductor -- each excellent musician making excellent individual music with the end-result of painful cacophony. If you buy my theory, then you much agree that it is disingenuous for us to maintain that the government does not belong in this discussion. We must think of our elected officials as a political group that represents precisely the interests of the populace, and thus balances out all of the other voices at the table. 

I do not hold out much hope for the business of news -- after all, keeping us informed is the job of serious news outlets like the New York Times, the Wall Street Journal and the BBC. And since these alternatives are still widely available, I personally do not care what others do -- these are the choices that we still have in America. As for the healthcare system, we must hold our politicians responsible for representing our interests and stopping this disease juggernaut in favor of promoting a healthy society.

Whom are we killing?

We are a society obsessed. Everywhere we go, there are soaps and detergents with antibacterial agents in them. Some of our food is irradiated to kill micro-organisms. Our milk is ultra-pasteurized in the name of sanitation. At the first sign of the sniffles, our healthcare providers eagerly prescribe antibiotics that today can cleanse your native flora with great efficiency. Our food animals, which are raised on factory farms in conditions that should be considered torture, are given antibiotics routinely, so as to prevent disease from galloping through their overcrowded quarters. Because of all these measures we are healthier today than ever before, right?

Well, not exactly. As a nation, our health is in the bottom third of all of the developed countries in the world. Despite the most expensive healthcare system on Earth, we have the biggest problems with access, and the quality of the product when we do access it is not that great. But aside from that, all this cleanliness has made a positive difference, of course... Well, no again! Some scientists think that our over-sanitized life style has contributed to the escalating rates of asthma and other allergic conditions. We know for certain that overuse of antibiotics is responsible for creating a cadre of superbugs that threaten to bring us back to pre-antibiotic era (if you don't believe me, just check out the FDA and the WHO web sites). The use of antibiotics in animal production (incidentally responsible for roughly 70% of all antibiotics utilized in this country) has not stemmed the tide of food-borne outbreaks, and has likely contributed to antimicrobial resistance that is affecting the human population. And yet, even healthcare providers by and large have bought into the benefits of sterilizing everything.

A small handful of scientists and authors are working hard to debunk this myth. The Union of Concerned Scientists, the Infectious Diseases Society of America, the Alliance for the Prudent Use of Antibiotics are just a few organizations struggling to bring the issue of antimicrobial agent overuse to the forefront of the political and legislative arena. Books by Michael Pollan and Barbara Kingsolver are raising awareness among lay public and driving the interest in returning to more humane and sustainable approaches to food production.

We as consumers must take matters into our hands. We can vote with our feet when it comes to what foods we choose to purchase and where. Locally produced whole foods are as a rule better for you, your family and the environment than foods grown thousands of miles away in dubious conditions. If your doctor urges you to take antibiotics for a minor cough, just say "no" (unless there is a solid reason to think that you have a serious bacterial infection) -- you will be doing both yourself and the society a favor by limiting the opportunities for superbug development. Finally, in this technologically advanced age, there is still one very low-tech intervention that can make all the difference in disease prevention: soap and water, just like mom said.

Since bacteria have been on this Earth orders of magnitude longer than humans, and have had the chance to evolve reliable mechanisms to evade our assault on them, would it not be smarter for us to learn to live with the ones that do not cause disease peaceably instead of trying to decimate them? Although we seem to be killing them with drugs, heat and radiation, are we really killing them? Or are we creating a more resilient race that is able to do ever increasing amounts of harm to our species?

Some thoughts about denominators

Let's face it: denominators keep numbers (and people reporting them) honest. Imagine if I said that there were 3,352 cases of a never-before-seen strain of flu in the US. To be sure, 3,352 cases is a large enough number to send us rushing to buy a respirator mask! But what if I put it slightly differently and said that out of the population of roughly 300,000,000 individuals, 3,352 have contracted this strain of flu. I think this makes things a little different, since it means that the risk of contracting this flu to date is about 1 in 100,000, a fairly low number as risks go. Now, I am going to give you another number -- 86. This represents the number of the novel H1N1 flu-related deaths in Mexico reported on April 25, 2009, by the health minister of Mexico, and at that time this flu had been thought to have sickened 1,400 people. This gives us the risk of death with the flu of roughly 6%, a very high risk indeed! Well, that was then. Now that we have all steadied our pulses, and the health authorities have gone back and done some testing, as of yesterday Mexico had confirmed 2,059, cases with 56 fatalities, equating to a 2.7% risk of dying with the disease. Still a high number, to be sure, but lower than what was though before.

In the US, we have had 3 fatalities among 3,352 cases reported as of yesterday, yielding the risk of death from H1N1 in this country of about 1 in 1,000. But, of course, the denominator of 3,352 persons represent only those who sought medical attention and got tested, so probably it is an underestimate of the true burden of this strain of flu, and necessarily also an over-estimate of its attendant mortality. Now, apply this to the situation in Mexico, and it's likely that the risk of death from H1N1 is also lower than what we have observed precisely due to the under-estimation of the denominator. 

So how could we get a true estimate of the numbers of people afflicted with the H1N1 influenza? Well, we could screen absolutely everyone (or more likely a large and representative group of individuals). Then what? Do we treat them all with anti-virals? Do we observe them? Since the Centers for Disease Control and Prevention recommends testing only severe cases and treating only persons at a high risk for complications, universal testing does not seem like a practical approach. So, the bottom line is that we are not likely ever to get at the correct denominator for the risk of dying with this disease, and any number that we get is likely to be an over-estimate of the true risk.

So, what are the lessons here? First, don't let anyone get away with only giving you the numerator, as that is not even a half of the story. Second, even when the denominator appears known, be skeptical -- does it really represent the entire pool of cases that are at risk for the event that the numerator describes? The likely answer will most of the time be "no". Clearly, it is the denominator that is the key to being an educated consumer of health information.

Writer's block

Here I am sitting at my computer trying to write a review on MRSA in the intensive care unit, and all of a sudden I cannot write -- everything is distracting me, I cannot figure out what I want to convey, or how I should structure the paper. This may well be a manifestation of information overload. When I type "MRSA" in the search engine PubMed, I get 12,214 hits! When I narrow it to "MRSA+ICU", it becomes a much more manageable, but probably not particularly comprehensive and still daunting 326. 

And herein lies the conundrum of evidence-based medicine: There are nearly 700,000 medical papers published annually, according to William Miser, MD, MA, who wrote that a clinician reading 2 articles per day in 1 year would fall over 9 centuries behind in his/her reading (Prim Care 2006;33:839-62)! Furthermore, the quality of these studies is far from uniformly good. So how does a busy clinician sift through this gargantuan amount of information in order to provide up-to-date care to their patients? Well, the answer is that some, probably more than any of us care to admit, don't; I call the type of medicine they practice the "15-years-of-experience-based practice". This is an insidiously dangerous type of practice, since from an early age we are taught to trust the greying temples and the confident and condescending demeanor. 

Unfortunately, the only recourse for us as patients is to be educated consumers of healthcare. Now, I am not implying that everyone needs to start reading the 700,000 studies that come out annually. I am not even implying that all of us need to follow the "breaking news" stories about health and disease; in fact, I would steer clear of those, since the sound-bite format lends itself to sensationalist half-truths. My view is that every patients needs to be empowered and unafraid to ask certain simple questions of their healthcare provider. "Why" is the most important question to ask (as in "Why do [that is what makes] you think I have this condition?" "Why are you ordering this test?"), followed by "What are the chances" (as in "What are the chances that the test will tell us what we need to know?" "What are the chances that the information from the test is trustworthy?" "What are the chances that the test will give us the wrong information and send us down the wrong path?"), finishing with "What actions will we take?" (that is, "What actions will we take based on the results of the test?" "What are the possible consequences [both positive and negative] of these actions, and what are the chances of each happening?") If we start with a somewhat skeptical attitude and expect to have our questions answered respectfully and completely, we may be able to weed out the up-to-date from the outdated experience. But that doesn't really help me with my writer's block, does it?

Too little too late?

The Washington post today reports that several stake holders in our healthcare system (the AMA, PhRMA, AHA, AHIP, to name a few) are meeting with President Obama today to discuss their commitment to cost-containment in healthcare (http://www.washingtonpost.com/wp-dyn/content/article/2009/05/10/AR200905100222).  Indeed, to someone who has been an observer of this area it seems a bit disingenuous, albeit a strategically obvious move. I don't know how many readers will remember the multi-million dollar campaign mounted by the same stake holders in the early 1990s during the Clinton administration against the then proposed overhaul of the system (the famous "Harry and Louise" ads were a part of this campaign). The idea was that introducing the kind of regulation into this industry would not only be un-American, but also might lead us onto the path of limited access and rationing.

Interestingly, this was not the first time in American history that a proposal to change how we deliver healthcare engendered such rhetoric. During the Truman administration, in mid-to-late 1940s, there was a strong movement afoot to reform medicine. Framed initially as "compulsory health insurance", it became better known as "socialized medicine", a moniker that to this day brings goose pimples to our necks along with the drab grey images of Communist demonstrations in the Red Square. That campaign was in fact so effective precisely because it implied that, should we pass such legislation, we would become either the Nazi Germany or the Communist Russia, the paragons of un-Americanism. With large amounts of money spent on effective advertising (a little known but affable and convincing actor by the name of Ronald Reagan was featured in many of the ads), the measure was gutted and forgotten until 1993, when similar tactics were once again employed by the opposition.

Now, with a strong Democratic leader in the White House, along with a near-veto-proof majority in Congress, and a staggering deficit, the former nay-sayers are eager for a place around the table. But is this enough? Are they hoping to replace legislative mandates with unenforceable commitments? To be sure, the issue is very complex. Many people and groups bring divergent agendas to the issue. And while I truly believe that there is no fundamentally evil intent to deceive the American people, we need to be wary of these agendas. Since the primary goal of a business is to make money, and since early in our history we chose to allow healthcare to fit a business paradigm, many of the stakeholders meeting with President Obama today will be looking out for their best interests (the AMA for the physicians, PhRMA for the pharmaceutical manufacturers, AHA for hospitals and AHIP for the insurance companies). On the other hand, since the healthcare industry is one of the major employers in this country, at least to some degree their interests overlap with those of the public as a potential engine of economic growth, a particularly relevant issue in this recession. 

So, the President and his team will be walking a tight rope in order to balance industry agenda with the interests of the American people. It would be easy to say that the current efforts of these industry groups are, in fact, too little too late. However, we have an accomplished politician in the White House, who seems to be able to negotiate important compromises without giving away the store. I am hopeful that Obama will make a good faith effort to work with these groups, and that this effort will result in strong legislative action that will create durable and enforceable regulations to ensure sustainable, equitable and high quality healthcare for all.

On trade-offs

Remember how your mom made you choose between a cookie and a piece of chocolate for dessert? Remember how shocked you were the first time it happened? "You mean I can't have both?" Now as an adult you stand in front of your closet packing for a trip and deciding between the brown loafers and the black heels, because surely you do not have room for both in your luggage.

Every day we make hundreds of choices, and by choosing one thing we are giving up something else. We mostly do this almost subconsciously (tea or coffee? paper or plastic? hot dog or hamburger?), though with some choices we need to think a little harder (vacation or a new roof?). On the other hand, some ostensibly simple decisions may have far-reaching consequences: should I take up smoking, should I watch TV instead of going for a walk, should I grab that greasy cheeseburger for lunch again?  

As citizens of a nation founded on self-determinism, we view the opportunity to make these choices as our inalienable  right. But with any right comes personal responsibility. Oddly, we seem to leave this right/responsibility doublet at the door when dealing with our health choices. Indeed, for many it is precisely the choice to have that cheeseburger while sitting in front of the TV or to pick up that cigarette or to put exercise at the bottom of the priorities list that leads to the logical trade-off between health and disease. But because the steps between that cigarette and heart attack are many, these choices, as if moves in a chess game, are removed from the check mate. Nevertheless, by picking up that cigarette, you have made a health trade-off.

Of course, today the medical science can pull us out of the abyss of near-death like never before. We have drugs and surgeries and other procedures to deal with the consequences of the choices we make. In fact, where is the trade-off in that? So, maybe mom was wrong (heavens!), and I can have both a cookie and a piece of chocolate? Not so fast. The treatments themselves represent a trade-off. That is, every time a pill or an injection or a scalpel invades your body, there is a chance for an adverse consequence. Also, we are now spending over 2 trillion US$ on healthcare annually in the US! And this represents that trade-off, that decision to have a cigarette. By choosing to smoke, we have implicitly decided that we would rather be spending all this money on healthcare rather than on, I don't know, a baseball game. Like with any budget, if you spend money on one, you may not be able to afford the other -- your choice!

So, unless we see no better way of spending our money than on the consequences of our near-sighted health choices, we had better make smarter decisions and think about trade-offs far down the road. And by the way, perhaps this means that we don't need a bigger and more costly healthcare system, but one that is more efficient. Who knows, perhaps we can provide everyone with access to quality healthcare that will not bankrupt our children. And with a piece of chocolate (or a cookie).   

Virgin blogger

Well, I have been contemplating starting a blog for some time, but was not sure how to approach it. Being a health services researcher, I obviously wanted to blog about healthcare in the US and elsewhere, but with so much already being written about it... well, what's the point? Nevertheless, I will try to take on some of the popular topics in the news and the literature and look at them from a different perspective, or devote some time to stuff that in my opinion is important, but is not getting the attention it deserves. That is, given that I have enough time to do this. And well.
