Medicine’s House of Cards – What Happens When We’ve Got It All Wrong

Medicine's House of Cards – What Happens When We've Got It All Wrong

I have to admit, the randomized, double-blind, placebo-controlled trial still holds a special place in my heart even after I have spent the past half-decade immersed in the shortcomings of our current data collection model.  As I discuss here, I understand now, the role of industry bias in publication of studies, the design limitations of randomized trials in accounting for biochemical individuality, and the many permissible aspects of randomized trials that allow for skewed outcomes (placebo washout, breaking blind with inert placebo, allowance of sedatives, etc).  I now understand that health is about so much more than is factored into these trials.  I have observed that patients can seem "just fine" on a basic lab screen and physical exam, and be anything but, if you know how to scratch beneath the surface.  As Marion Nestle says, on the subject of what nutrition research typically assesses: "nutrients that are out of their food context, foods that are out of their dietary context, and diets that are out of the context of lifestyle."

Studying nutrients the way we study drugs makes no sense, not only because the form of the nutrient employed in these studies is typically a pharmaceutical form, but because nutrients don't work in isolation – they work and heal in the context of other nutrients, and of the lifestyle.

So, while we, firmly positioned in the holistic camp, believe that natural medicine heals, many of us still feel compelled to prove it.  What are we using as the standard for that proof?  What if we are looking behind the curtain to find that Wizard isn't quite what we imagined?

A provocative and important piece in the Mayo Clinic Proceedings should change the way that medicine is practiced.  It probably won't.  Here is the question:

"How many contemporary medical practices are not any better than or are worse than doing nothing or doing something else that is simpler or less expensive? This is an important question, given the negative repercussions for patients and the health care system of continuing to endorse futile, inefficient, expensive, or harmful interventions, tests, or management strategies."

In this investigation, Prasad et al analyzed 2044 original articles published in the New England Journal of Medicine from 2001-2010 and classified the articles based on whether they tested a new or existing treatment and whether the results challenged or supported its efficacy.  They found that 40.2% of the articles argued for "medical reversal" or – stop doing this because it's actually not evidenced based.  A total of 128 medical practices were brought into the harsh light of evidence over those 10 years which means that a major memo should have been disseminated and doctors around the country made aware of the need to change what they were doing – or, at least, make patients aware of the evidence calling the practice into question.  To the contrary, Prasad et al discuss:

"Although there is a weak evidence base for some practice, it gains acceptance largely through vocal support from prominent advocates and faith that the mechanism of action is sound. Later, future trials undermine the therapy, but removing the contradicted practice often proves challenging."

They reference a related review in the British Medical Journal that evaluated 3000 medical practices and found that more than one third are effective or likely to be, 15% are harmful, and 50% are unknown.  I would add to this that the assessment of "no net benefits" in many of these short-term trials with limited controls for patient individuality are ill-equipped to estimate important functional risks to physiology that may take months or years to emerge and may never be linked to the original treatment exposure.  Prasad loses me; however, when they start to apply a framework of using evidence to dismiss previous signals of risk.  Establishing efficacy is one thing that these trials appear to be far less well-equipped to handle than we all have been led to believe, by modern medicine.  Establishing risk is a far more complex endeavor and should rely, heavily, on the precautionary principal, which demands that, if there is any signal of harm, caution is exercised.  Data such as this, and related meta-analyses are not designed to establish safety, and dismissal of previously identified risks is not the same as identifying a lack of efficacy.

We have learned this lesson through the push and pull with industry around "studies" intended to assure the public of safety and to erase any concerns about risk from the board.  Only after decades of accumulated damage is the unavoidable population-based data able to overturn the pharmaceutical agenda.  It's happened again and again – cigarettes, DES, thalidomide, COX inhibitors, BPA, the relationship between neurological damage and vaccination.

This is not the first time that objective investigations into the shortcomings of our evidence base have been brought into the spotlight.  The Cochrane Database was reviewed in 2004 to demonstrate that 47.8% of assessments concluded that there is not sufficient evidence to endorse the queried practice or intervention.  In 2011, this trend had not changed with an insufficient evidence rate of 45%. (

Close to my heart was a recent related paper that explored this phenomenon in the world of obstetrics.  Practice bulletins are the premise for assessing "gold standard" applications of science in the service of patient care.  Certification testing is based upon these bulletins, as are malpractice allegations.  In this paper, 84 practice bulletins discussing 717 individual recommendations.  Of the obstetrical recommendations in this assessment, only 25.% are considered to reflect "good and consistent evidence".  The rest divided into 39.7% for limited or inconsistent evidence and 34.8% for consensus and opinion.   When I consider the practice of continuous fetal monitoring, monthly ultrasound, glucose tolerance test, episiotomy, and treatment of Group B Strep in the face of evidence contradicting its utility, this does not surprise me.  If departure from physiologic home birth is argued on the basis of "safety", where is the data to support that?  I would offer, as have others, that our maternal and infant mortality rates, and large scale studies such as this and this also argue for a re-examination of just what we think we are doing to women in this country.

The take-home to this review is to emphasize the fact that conventional medicine often employs consensus opinions arrived at through "expert" discussions.  Even if evidence were driving the ship, the evidence itself is compromised by conflicts of interest that have been well exposed.  The more you can take your health into your own hands and employ low risk, potentially high yield natural interventions after attending to diet, exercise, and stress management, the less you will get caught in the avalanche of cards when the house falls.

Medicine's House of Cards

Dr. Brogan should be on a Presidential panel on how to improve health care in this country. I commend her on this excellent critique.  So many people have lost trust in the "one-size-fits-all conventional medical model. We know we are complex, so why does the medical industry perpetuate the semantic notion that patient 1 is patient 2 is patient 3?   And we are onto the scientists-for-hire who write reports favorable for the pharmaceutical industry while attacking "unproven alternatives."  Actually, after fifty years of scientific studies proving no link between tobacco and lung cancer most scientific studies have a credibility problem. If conventional medicine is to be relevant in a world of increasing emotional and environmental stresses then doctors need to be trained to do more than reach for a prescription pad.  


Trials/Foggy statististics

I agree that when health info is offered by attractive but clueless news-anchors and endless drug commercials, the result is confusion; a mind crippling distraction from reality.  The food/healthcare conversation in this country is so absurd I had to go to the basic chemistry and energetics of our molecular makeup to find the truth....


Disease is a result of bad fats/carbs/low nutrient produce/processing, metal loads, various toxic chemicals and mineral deficiencies under a climate of media and economic stress.


Corporate "Science" now tries to perpetuate a flawed industrial paradigm with all these phony misdirected make-work investigations.   True causes and solutions remain out of the picture by choice and  denial.   It is forbidden to go there...  99% of chemicals remain untested, mineral levels are ignored, metal burdens are deemed "safe" and can't be detected with standard blood testing, cheap alternatives like Vit C, HBOT, peroxide or baking soda are ignored, deadly soft drinks and damaged fats are in all commercial foods and mass media has become a fear driven marketing mechanism.

This how The State of Florida protects chemical ag, mining and chemicals...They declare that manatee, dolphin and fish kills are "natural occurrences" after defunding water tests in fertilizer polluted/toxic alga business gets done!

Govt. agencies, corporate industry and universities have been in a moneymaking three-way for too long and the collective understanding of everything has become a grim fairy tale...geeez.  "Peer reviewed" is academia-speak for industry approved.
