I could have titled this piece "have the deceivers been themselves deceived?"

Recent revelations have shown that biomedical ghostwriting is a scourge that some physicians and scientists -- who are clearly lacking ethics, insight and perhaps an understanding of psychiatric defense mechanisms such as rationalization -- engage in all too often, as it taints the corpus of worldwide scientific literature.

(I covered the issues related to ethical and justified claims of provenance for scientific writing in my post "Wyeth: Ghostwritten Papers Fake, But Accurate" here along with a discussion of why lay leadership of biomedical R&D organizations was not a good idea. Such leaders cannot vouch for the scientific fairness and accuracy emanating from their own organizations.)

One should examine the evidence in a first-person manner. The New York Times has made available secret documents and emails secured by Senator Grassley on Wyeth's ghostwriting practices. These documents were unsealed by a judge in a personal injury lawsuit and chronicle Wyeth's use of a medical writing company to prepare articles for publication in medical journals.

Wyeth said all the articles are "scientifically accurate" and that "it is a common practice in the pharmaceutical industry to work with such firms" (and, by implication, to falsify claimed authorship). As justification for clearly unethical practices, this is a rather poor argument, being a classic logical fallacy known as the Appeal to Common Practice:

Description of Appeal to Common Practice
The Appeal to Common Practice is a fallacy with the following structure:

1. X is a common action.
2. Therefore X is correct/moral/justified/reasonable, etc.

That said, these documents raise an important question of a systemic nature:

Have the scientific ghostwriting deceivers themselves been deceived
regarding biomedical reality by these practices?

Might they genuinely believe they are contributing to the scientific literature based on their own erroneous notions, the latter based upon a scientific literature contaminated by other ghostwriters?

To illustrate this point, in the New York Times online document pool, we discover that Dr. Gloria Bachmann, Associate Dean for Women's Health and Professor of OB/GYN and Medicine at UNDNJ-Robert Wood Johnson Medical School was presented with a tidy ghostwritten article entitled "The Importance of Treating Vasomotor Symptoms" (in peri- and post-menopausal women) by authors "TBD" (to be decided):

about which Bachmann wrote the following in an email to the true authors' organization:

"Outline is excellent as written. I would like to try for publication as a review article in Obstetrics and Gynecology. We would have to change the title to "Vasomotor Symptoms: Evidence Based Treatment Options" or a title that emphasizes the data driven writing style."

Here is an image of the email:

She found the content OK and agreed to review it.

Apparently, only minor changes were made. (Bachmann should have received accreditation in the acknowledgments section for reviewing the article, and/or a position far down the authorship hierarchy if she actually added some material).

Instead, the reverse occured.

The published document appeared with Bachmann as first (and only) author after Bachmann submitted it to a medical journal under her name, itself unethical. See what "Authors TBD" morphed into in the image below:

Here is how the true authors, medical writers for DesignWrite, the medical writing and communications company retained by Wyeth to write the article, received credit:

Unbelievable.

Bachmann has since stated that she believed she was adding to science by engaging in this deceit. From the New York Times:

The article, a nearly verbatim copy of the DesignWrite draft, appeared in 2005 in The Journal of Reproductive Medicine, with Dr. Bachmann listed as the primary author. It described hormone drugs as the “gold standard” for treating hot flashes and was less enthusiastic about other therapies.

The acknowledgments thanked several medical writers for their “editorial assistance,” not disclosing that those writers worked for DesignWrite, which charged Wyeth $25,000 to generate the article.

Dr. Bachmann, who has 30 years of research and clinical experience in menopause, said she played a major role in the publication by lending her expertise. Her e-mail messages do not reflect contributions she may have made during phone calls and in-person meetings, she said. ["May have made?" This gossamer excuse is embarrassing to me, as an academic myself - ed.]

“There was a need for a review article and I said ‘Yes, I will review the draft and make sure it is accurate,’ ” Dr. Bachmann said in an interview Tuesday. “This is my work, this is what I believe, this is reflective of my view.”…

She is quite off base regarding scientific authorship and "this being her work", but what also needs examination is her "lending her expertise" and her agreeing with the paper as "reflective of her view."

The paper itself lists many references, for example these:

Here is, then, the dilemma, another major problem posed by ghostwriting:

How many of the cited references, which contributed to Bachmann's beliefs regarding these drugs, were themselves ghostwritten and potentially biased, or otherwise influenced by drug companies?

For that matter, how many studies with different ("negative") conclusions on these subjects were suppressed from publication by industry pressure? 

Bachmann's own "expert opinions" about these matters may be based upon false or misleading information she's read in other journals, the percentage of which are genuine vs. ghostwritten or industry-influenced being an unknown at this point in time.

While I believe Bachmann is most likely rationalizing away the unethical nature of attribution without fair and justifying contribution, perhaps fueled by additional motives of academic portfolio building and perhaps present and future potential pecuniary gain, it is possible she is being genuine about agreeing with the "science" in the paper.

However, her agreement may be predicated upon her own tainted expertise -- tainted by reading ghostwritten or industry-influenced articles in her area of specialty.

Will we ever be able to peel back all the layers of the ghostwriting onion to get to the core of impartial and objective scientific articles related to drugs and medical devices? Perhaps not, but the practice must stop going forward.

Tainted literature creates tainted scientific knowledge, the carriers of which may then further taint the knowledge base (with the best of intentions and with firm belief in the fairness and accuracy of their activities, of course).

Practitioners of evidence-based medicine may be unwittingly practicing "evidence-tainted medicine", or "pseudo-evidence based medicine" as described by others on this blog.

Such are the systemic risks of the scourge of ghostwriting.

Aug. 31, 2012 Addendum:

I was made aware of the following 2011 paper thanks to a post by Dr Howard Brody on the Hooked: Ethics, Medicine and Pharma blog:  "Why Does Academic Medicine Allow Ghostwriting?  A Prescription for Reform" by Jonathan Leo, Jeffrey R. Lacasse, and Andrea N. Cimino

The paper also observes:

Due to its secretive nature, it is difficult to quantify how many invisible corporate authors haunt the medical literature.

The paper is worth reading in its entirety and as of this writing is available free at the link above.

As I posted yesterday, the increasingly noisy debate about health care reform in the US has not dealt much with the issues we often discuss on Health Care Renewal. These include problems in how health care organizations are led which threaten physicians' and other health care professionals' core values using tactics including perverse incentives, deception, and intimidation.
Last night, however, President Obama held a news conference mostly devoted to health care issues, in which he stressed the importance of changing not just how health insurance works, but how health care decisions are made. As Newsweek's "The Gaggle" blog reported,

Can I guarantee that there are going to be no changes in the health care delivery system? No. The whole point of this is to try to encourage changes that work for the American people and make them healthier. The government already is making some of these decisions. More importantly, insurance companies right now are making those decisions. And part of what we want to do is to make sure that those decisions are being made by doctors and medical experts based on evidence, based on what works, because that's not how it's working right now.


So what the President seems to be advocating is making health care more evidence-based, perhaps in the formal sense of evidence-based medicine.

As a card-carrying evidence-based medicine advocate, I certainly agree, but let me reiterate that evidence-based medicine is not just medicine based on some sort of evidence. As Dr David Sackett, and colleagues wrote [Sackett DL, Rosenberg WM, Muir Gray JA, Haynes RB, Richardson WS. Evidence-based medicine; what it is and what it isn't. BMJ 1996; 312: 71-72. Link here. ]

Evidence based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research. By individual clinical expertise we mean the proficiency and judgment that individual clinicians acquire through clinical experience and clinical practice. Increased expertise is reflected in many ways, but especially in more effective and efficient diagnosis and in the more thoughtful identification and compassionate use of individual patients' predicaments, rights, and preferences in making clinical decisions about their care. By best available external clinical evidence we mean clinically relevant research, often from the basic sciences of medicine, but especially from patient centred clinical research into the accuracy and precision of diagnostic tests (including the clinical examination), the power of prognostic markers, and the efficacy and safety of therapeutic, rehabilitative, and preventive regimens.

Furthermore,

Evidence based medicine is not 'cookbook' medicine. Because it requires a bottom up approach that integrates the best external evidence with individual clinical expertise and patients' choice, it cannot result in slavish, cookbook approaches to individual patient care. External clinical evidence can inform, but can never replace, individual clinical expertise, and it is this expertise that decides whether the external evidence applies to the individual patient at all and, if so, how it should be integrated into a clinical decision.

One can find other definitions of EBM, but nearly all emphasize that the approach is designed to appropriately apply results from the best clinical research, critically reviewed, to the individual patient, taking into account that patient's clinical characteristics and personal values.

So far, so good. I believe the proper application of "real" (as described above) evidence-based medicine has the potential to improve patient outcomes while moderating health care costs. However, we have pointed out how problems arising from concentration and abuse of power in health care threaten the evidence-based medical ideal.

First, there are major problems with the development of the sort of clinical research evidence required by the EBM process. We have discussed how clinical research is frequently manipulated by those with vested interests in producing results that favor the products or services that they sell. The critical review process inherent in EBM is meant to cope with less than optimally designed and implemented research. However, the process was designed to cope with honest mistakes and inevitable trade-offs, not deliberate manipulation by vested interests.

Worse, we have discussed how vested interests may engineer the suppression of research when manipulation fails to produce the desired results. The EBM process assumes that the research on which decisions should be based is an unbiased sample of research that was done (and done to advance science, not commercial or ideological interests). When research whose results are unwanted by vested interests is suppressed, the resulting distortion of the evidence base may irretrievably bias the EBM process.

Finally, we have posted about how vested interests have distorted the discussion, dissemination, and teaching of the results of clinical research. They may develop systematic stealth marketing campaigns, often employing supposed "key opinion leaders," who are paid on the side by marketers, and using "medical education and communication companies"as marketing fronts whose publication strategies include deceptive tactics such as "ghost-writing."

Thus, a rising tide of "pseudo-evidence based medicine" threatens to overwhelm even the most conscientious physicians trying to practice evidence-based medicine.

So, while I applaud President Obama's advocacy of reforming health care to emphasize what the best evidence suggests really works, I do not think this effort will get far unless we deal with the rising tide of pseudo-evidence based medicine. As a minimum, we need full and detailed disclosure of all the relationships among vested interests and medical research and education, and a much greater role for research and education that is not subsidized by corporations bent on using research and education to market their products and services.
