The $20 Million Dollar Journal Editor

Last week, the Milwaukee Journal-Sentinel reported on a royally paid journal editor:

In 2002, Thomas Zdeblick, a University of Wisconsin orthopedic surgeon who has pocketed millions of dollars in royalties from the spinal device maker Medtronic, took over as editor-in-chief of a medical journal about spinal disorders.

It would be the beginning of a beautiful friendship.

In the years to come, Zdeblick would receive more than $20 million in patent royalties from Medtronic for spinal implants sold by the company. And the medical journal he edited would become a conduit for positive research articles involving Medtronic spinal products, a Journal Sentinel analysis found.

Zdeblick took over editorship of the Journal of Spinal Disorders & Techniques seven years ago. Since then, studies involving Medtronic spinal products or that were funded by Medtronic appeared in the journal at least once per issue, on average.

Dozens of studies that mentioned Medtronic products have been published while Zdeblick has been editor. But in issue after issue, readers of the journal were not told that he was receiving millions of dollars in royalty payments from Medtronic at the same time.

Most of the time the articles, including some co-authored by Zdeblick himself about devices for which he gets royalties, had good things to say about the Medtronic products. Only on a small number of occasions did the articles find major problems with Medtronic devices.

And often the articles did not disclose financial ties the authors had to Medtronic.

Here are some specifics:

From 2003 through 2007, Zdeblick got more than $19 million in royalty payments for spinal devices from Medtronic, according to a January 2009 letter by U.S. Sen. Charles Grassley (R-Iowa), who has been investigating payments to orthopedic surgeons by Medtronic. In 2008, Zdeblick got another $2 million from Medtronic from royalties and working as a consultant, according to UW records.

To assess the relationship, the Journal Sentinel reviewed every article published in the journal since Zdeblick became editor.

The journal is published seven or eight times a year and typically has a dozen or so articles. The articles were searched to see if Medtronic products were used as a part of the study or if the study was funded by Medtronic.

At least 70 such articles were found in 56 issues of the journal from 2002 through October 2009.

• A 2005 study by researchers in France found favorable preliminary results with Medtronic's Maverick artificial disc.

In 2007, Medtronic paid Zdeblick $144,000 in royalties for the Maverick disc, according to Grassley's letter.

•  In August 2009, Zdeblick co-authored a study that involved Medtronic's Premier Anterior Cervical Plate as well as the plate of another company, Synthes. The study involved using two different kinds of bone grafts with the plates. Zdeblick got $654,000 in Premier royalties from Medtronic in 2007.

•  Zdeblick also co-authored three articles, in 2002, 2003 and 2005, involving Medtronic's BMP-2 and the LT-Cage, a device that paid him $1.4 million in royalties in 2007. None of those studies disclosed that he received millions of dollars in royalties from Medtronic.

Often articles in the journal had good things to say about Medtronic products:

•  In the 2002 study, Zdeblick and the co-authors concluded that BMP-2 and the LT-Cage led to a solid union and high fusion rates. In the 2003 study they found that BMP-2 may become 'the new gold standard.'

•  In a 2006 study, a different group of authors concluded that BMP-2 when used with a hip bone graft significantly improved the success of the fusion surgery with minimal risk to the patient. The 2005 French study of Medtronic's Maverick artificial disc that did not involve Zdeblick concluded it was a 'promising therapeutic technique.'

Dr Zdelblick declined to comment for the Journal-Sentinel, but:

In a statement, a spokesman for the spinal journal said Zdeblick has disclosed his financial relationship with Medtronic to the company that publishes the journal, Wolters Kluwer Health/Lippincott Williams & Wilkins.

All manuscripts submitted to the journal go through a rigorous review process using reviewers who have an objective viewpoint, Robert Dekker, director of communications with Philadelphia-based Wolters Kluwer Health & Pharma Solutions, said in a statement. 'Thanks to our strict peer review policies and processes, we have no concerns about the existence of this relationship,' Dekker said in an e-mail.

Dekker declined to provide a list of the reviewers used by the journal or information about their financial relationships with device companies. He also declined to comment on how Zdeblick made decisions about manuscripts and reviewers.

Of course, as the Journal-Sentinel pointed out, editors can make publication decisions independent of the recommendations of peer-reviewers. They also are free to select peer-reviewers who might have a particular viewpoint about a manuscript, its topic or authors, and to make and enforce editorial suggestions for changes in manuscripts.  It is beyond me what good that disclosure of conflicts of interest to a for-profit publishing corporation does in the absence of further disclosure.  Keep in mind also that the division of Wolters Kluwer that publishes the journals, Wolters Kluwer Health & Pharma Solutions, not only publishes journals and textbooks, but "provides marketing and publications services, business intelligence products, and advanced analytical tools and services" to pharmaceutical corporations.

Furthermore,

'It's absolutely a conflict,' said Richard Smith, the former editor of the British Medical Journal.

At a minimum, Zdeblick's conflict should be fully disclosed by his journal whenever a study involving a Medtronic product is published, said Smith, the author of 'The Trouble with Medical Journals.'

However, because he makes so much money from Medtronic royalties, he really should not be editing the journal at all, Smith said.

Just to add icing to the cake, Prof Margaret Soltan pointed out on her University Diaries blog that Dr Zdeblick is not only a journal editor, but a Professor and Chairman of Orthopedics and Rehabilitation at the University of Wisconsin.  In addition, his web-page at the University notes that he is on the editorial board of another orthopedics journal, Spine, also published by Wolters Kluwer Health. 

So here we go again.  How should we assess the objectivity of an ostensibly scholarly medical journal whose editor was made rich by royalties from a company whose devices were often evaluated in the articles published in the journal?  How should we assess the honesty of a journal editor who received millions in royalties from Medtronic, but who only deigned to disclose as an author in his own journal, "One or more of the author(s) has/have received or will receive benefits, (e.g., royalties, stocks, stock options, decision making position) for personal or professional use from a commercial party related directly or indirectly to the subject of this manuscript." (as in Zdelblick TA, Phillips FM. Interbody cage devices.  Spine 2003; 28: S2-S7.)  (Note that this sort of disclosure seems to be standard operating procedure for orthopedic surgeons who make millions from royalties and consulting fees, e.g. see this post.)

Prof Zdelblick had numerous opportunities to influence his colleagues, trainees, and students in his roles as journal editor, journal editorial board member, author of scholarly articles, and professor and chair of orthopedics.  At the very least, the people who read his journal or his articles, listened to his lectures, or participated in his clinical teaching should have at least had the opportunity to judge for themselves whether being paid over $20 million might have just biased what he wrote and said a tiny bit.  But can anyone doubt that $20 million dollars would profoundly influence one's thinking?  Can anyone doubt that an inventor who got rich from royalties might not be more enthused about the use of the devicesthat generated the royalties than would an academic whose salary is unrelated to the use of any device?   It seems to be an abuse of entrusted power for a journal editor, professor, and department chairman not to clearly disclose such huge conflicts of interests to readers, learners and colleagues.

This is just the latest vivid example of the conflicts of interest that permeate health care.  When multi-million dollar men pretend to be unbiased editors and professors, is it any wonder that we regularly overuse and overvalue the devices and drugs that they are selling?

How Industry Views the Research It Sponsors

We have posted frequently about threats to the integrity of the clinical evidence-based, and to the practice of evidence-based medicine.  In particular, we have discussed how research may be manipulated in favor of vested interests, or suppressed when the results do not favor such interests.

Last week, the British Medical Journal electronically published a set of guidelines for how industry sponsored clinical research ought to be published, sponsored by the International Society for Medical Publication Professionals.  The authors came from pharmaceutical companies (Johnson & Johnson, AstraZeneca, Pfizer and Cephalon), medical device companies (LifeScan), and medical publishing and medical education and communication companies (John Wiley & Sons, Excerpta Medica, Field Advantage Medical Communications, PharmaWrite, and Knowledgepoint 360 Group).  [Graf C, Battisti WP, Bruce-Winkler V et al. Good publication practice for communicating company sponsored medical research: the GPP2 guidelines.  Brit Med J 2009; 339:b4430.  Link here.]

These guidelines are remarkable for the questions they raise about how people from industry view clinical research and how it should be reported in medical journals. 

Who's in Charge?

Nowhere does the article acknowledge that any one person has overall responsibility for a research project.  Clinical research projects funded by the US National Institutes of Health, Agency for Healthcare Quality and Research, and other federal agencies must have "principal investigators," who are the people who take overall scientific responsibility for the project.  The Graf et al article does not use this or an equivalent term.   There is no sense that they expect anyone to be in completely in charge of industry sponsored research. 

Particularly confusing is the following passage:

Before writing begins one author (a lead author, who may also be guarantor) should take the lead for writing and managing each publication or presentation. One author (identified as guarantor) should take overall responsibility for the integrity of a study and its report.

Here are some questions it raises.  If the guarantor could be chosen only when writing a paper is contemplated, which presumably could be years after the study that the paper would report was designed and implemented, who then would have been responsible for study "integrity" before the guarantor was chosen? Who would chose the guarantor for a particular paper? If a study generates more than one paper, could they each have a guarantor, and then how could they share responsibility for study "integrity?"  If the guarantor and lead author of a paper are different people, how would they share responsibilities, what would happen if they were not to agree, and who would be finally accountable?

So the guidelines seem to completely diffuse accountability for research projects, and the reports written about them.

Who is an Author?

In my experience with US federally and foundation funded research, research papers are written by the investigators, the people who actually did the research project.  However, in the guidelines by Graf et al, the concept of authorship is also ambiguous.  They suggest that "recognised criteria should be used to determine which of the contributors to an article should be identified as authors."  This is already confusing, since how could one be a "contributor" to an article without authoring it?  A later discussion of "contributors" as "investigators, sponsor employees, and individuals contracted by the sponsor" was not very helpful.  Why should a "sponsor employee" who was not an "investigator" be a "contributor" or an "author," whatever the distinction is between them? 

So the guidelines blur distinctions among people who do research, and people employed by companies that may have vested interests in the research favoring their products or services.

What do Professional Medical Writers Do?

There has been considerable recent controversy, not directly acknowledged by Graf et al, about the role of professional medical writers in the reporting of research and the writing of ostensibly scholarly medical publications, particularly in cases where the writers were paid by and reported to corporate sponsors, but were not recognized as such in the publications they wrote (a type of ghost-writing).  The guidelines by Graf et al do not clearly explain what the roles of professional medical writers ought to be:

Professional medical writers must be directed by the lead author from the earliest possible stage (for example, when the outline is written), and all authors must be aware of the medical writer’s involvement. The medical writer should remain in frequent contact with the authors throughout development of the article or presentation. The authors must critically review and comment on the outline and drafts, approve the final version of the article or presentation before it is submitted to the journal or congress, approve changes made during the peer review process, and approve the final version before it is published or accepted for presentation.

Note that this would not prevent a professional medical writer from writing an initial outline, the first draft, and all subsequent drafts. including the final draft of a paper. (The role of an "author" above might be restricted to simply commenting on and accepting the outline and all drafts.) Thus, the "authors" could function as distant editors, and the professional writer would assume authorship, as most people would define it. (Merriam-Webster: "1. one that originates or creates 2. the writer of a literary work.")

Furthermore, while the professional writer could take one the role of authorship, the guidelines do not require him or her to publicly acknowledge this role:

Professional medical writers, depending on the contributions they make, may qualify for authorship. For example, if a medical writer contributed extensive literature searches and summarised the literature discovered, and by doing so helped define the scope of a review article, and if he or she is willing to 'take public responsibility for relevant portions of the content' then he or she may be in a position to meet the remaining ICMJE criteria for authorship.

Presumably, a professional writer could dodge authorship by simply being "unwilling" to take such public responsibility.

So the guidelines apparently condone nearly all functions commonly assumed to be those of an author to be performed by a professional writer paid directly by the sponsor, without the writer being listed as an author.  The guidelines thus appear to condone ghost-writing in its most pernicious form.

Who Owns and Analyzes the Data?

Cases in which various the implementation and analysis of clinical research seems to have been manipulated to favor vested interests have raised concerns about the integrity of the data collected in the course of a research project, and how it is analyzed.  This is what Graf et al say about the ownership and use of the data:

Sponsors have a responsibility to share the data and the analyses with the investigators who participated in the study. Sponsors must provide authors and other contributors (for example, members of a publication steering committee or professional medical writers) with full access to study data and should do so before the manuscript writing process begins or before the first external presentation of the data. Information provided to the authors should include study protocols, statistical analysis plans, statistical reports, data tables, clinical study reports, and results intended for posting on clinical trial results websites. Sufficient time should be allowed for authors and contributors to review and interpret the data provided and to seek further information if they wish (for example, access to raw data tables or the study database).

The guidelines by Graf et al suggest that the company that sponsors the research should own the data. The investigators who collected the data and implemented the research project should not. At best, the company should "share" summaries, analyses, or pieces of the data, but at best investigators could have only "sufficient time" to "seek ... access to raw data tables or the study database."

So the guidelines would allow corporate research sponsors to analyze the data from studies evaluating their own products and services as they see fit, and the scientists who implemented the study and collected the data could only ask for access to it. 

Summary

The guidelines by Graf et al seem based on a very strange conceptualization of clinical research. In their view, no individual may be responsible for a clinical research project. Research data is controlled by the company that paid for the project, not scientists who implemented the research and collected the data. Research papers may be written by anonymous professional writers while the scientists who did the research only need to review and approve what they have written.

So why should anyone give credence to industry sponsored research?

We have discussed numerous instances in which clinical research was manipulated in favor of vested interests, and when clinical research whose results did not favor vested interests was suppressed. In most cases, the vested interests were held by for-profit pharmaceutical, biotechnology or device anufacturers acting as research sponsors. The guidelines by Graf et al seem to have been cleverly written to to employ comforting platitudes while licensing manipulation and suppression.  They should inspire no confidence in the integrity of industry sponsored research.
