JAMA Article Begs Key Questions About Case of Contaminated Heparin

There was a recent reminder of the case of the tainted heparin, which begged more questions than it answered.  (A case summary is appended to the end of this post, and nearly all our posts are here.)  The case is of fundamental importance because it involves the failure of pharmaceutical companies to fulfill their core mission, to supply pure, unadulterated drugs.   Three years later, how the heparin was adulterated, and who was responsible are still unknown.
JAMA just published a major news article (Kuehn BM. As production goes global, drug supply faces greater risks to safety, quality.  JAMA 2011; 306: 811-813.  Link here.) This, in turn, was based on a five page case study of the heparin incident in a report by the Pew Health Group entitled "After Heparin: Protecting Consumers from the Risk of Substandard and Counterfeit Drugs" (link here).  Reading between the lines, the Kuehn article raised several questions which it did not seek to answer, but which we have raised previously.

Why Didn't Baxter Look the Gift Horse in the Mouth?

The JAMA article noted that in general, "pharmaceutical companies are shifting the production of drugs and drug ingredients to emerging economies - primarily India and China - to save money."  [italics added for emphasis]  Also, "Many emerging economies do not have robust regulatory systems, and regulators from the United States or other countries may face hurdles in trying to oversee production in these nations."

Why were Baxter International executives not concerned about the quality of a drug offered cheaply from firms in countries with little regulatory oversight? 

Note that we have been asking versions of this question since 2008, e.g., "How hard did Baxter scrutinize the production of the drug? How hard did SPL scrutinize its production? Did Baxter, SPL and/or the FDA realize the drug was being produced in an unlicensed Chinese chemical factory which had never been inspected by the Chinese or US government? If they did, why did they accept its product? If they didn't, why didn't they know?" - from this post on February, 16, 2008.

Who Is Responsible for the Complexity and Opacity of the Out-Sourced Supply Chain?

The article stated, "In addition to becoming more global, the drug supply chain has also become more complex, .... Drug ingredients are now imported from 150 countries, and multiple suppliers, producers, and distributors may be involved in the production and import of a single drug." 

In particular, the article noted that "Baxter relied on the assessment of another company when it began receiving heparin from the plant through which the adulterated drug came."  (The nameless other company was Scientific Protein Laboratories.)  Also, it noted that the supply chain began at "the primitive workshops that extract heparin crude by cooking and drying pig intestines" and proceeded to "the companies that consolidate materials from many such workshops and sell them to the factories that produce heparin."  The article did not discuss how this particular supply chain came into existence.

Did not drug companies in developed countries, like Baxter International in this case, create these convoluted supply chains (mainly to save money, as noted above)?  If not, did they not at least enable the creation and operation of these chains by purchasing their products without asking too may questions?  In any case, the supply chain's complexity and opacity arose out of individual humans' decisions, not an act by a deity. 

Why Have no Individuals Been Held Accountable? 

The article noted that the Pew report suggested, "increasing the financial penalties and allowable prison terms for individuals and companies who violate the rules from their current maximums of $10 000 or 3 years in prison." The implication was that these penalties have proven insufficient.  However, the article failed to note that so far in the case of the tainted heparin, no such penalties have even been sought.  To my knowledge, neither Baxter International, Scientific Protein Laboratories, nor any individual who worked for them has ever been charged with any violation of "the rules" that could result in any penalty as much as "$10 000 or 3 years in prison."    I have asked repeatedly why so far there has been no obvious effort to hold any individual accountable for the contaminated heparin?  (see this post from July 19, 2010, in which I noted legal actions against doctors who implanted IUDs imported from and approved in Canada and asked, "why are we so vigorously pursuing individual doctors for an apparently technical violation of laws that did patients no apparent harm, when we are not pursuing health care corporate executives for selling adulterated drugs that likely killed patients? 

Why Are the Key Issues In This Case Still So Anechoic?

Neither the JAMA article nor the heparin case study in the underlying Pew report directly addressed these questions.  The JAMA article also omitted such details as the name of the company from which Baxter directly purchased the heparin (Scientific Protein Laboratories) and the total number of deaths that may have been related to the heparin.  (It only mentioned 3 deaths related to heparin, while the Pew Report noted the FDA got reports of 68, six more of which it allowed were "possibly caused by the adulterant, 24 were unlikely, and 35 were unassessable.")  As mentioned above, the JAMA article seemed to imply that criminal penalties have been applied to corporate executives whose companies may have profited from cheap but defective out-sourced drugs (but none have been applied in the heparin case).   Ironically, while the JAMA article identified the "culprit" for the adverse events in the heparin case, it used the word to refer to the compound that adulterated the heparin, not those who added it, or who enabled its addition. 

Summary

Thus, the public discussion in the main-stream medical media of the case of the adulterated heparin is still remarkably squeamish even three plus years after it first became public.  While the heparin case has made it into major medical journals, it still simply is not done to even publicly discuss whether the leaders of health care organizations who become rich partly as a result of decisions such as the unsupervised, uninspected, apparently barely considered out-sourcing of heparin to be accountable when these decisions turn out to have adverse effects on patients.

If we cannot even discuss the accountability of leaders of health care organizations, how can we hope to actually hold them accountable?  

To repeatedly reiterate, as long as the leaders of health care organizations are not held accountable for the results of their decisions on health care quality, cost, and access (even in such extreme quality violations as those resulting in multiple patient deaths), we can expect continuing decisions that sacrifice quality, increase costs, and worsen access, but that are in the self-interest of the people making them.


To really reform health care, we must hold health care organizations and their leaders accountable (and not blame all the problems on doctors, other health care professionals, patients, and society at large).

Case Summary

- We have posted several times, recently here about the tragic case of suddenly allergenic heparin. Although heparin, an intravenous biologic anti-coagulant, has been in use for over 70 years, serious allergic reactions to it had heretofore been rare. Starting late in 2007, hundreds of such reactions, and 21 deaths were reported in the US after intravenous heparin infusions.All the heparin related to these events in the US was made by Baxter International.


- We then learned that although the heparin carried the Baxter label, it was not really made by Baxter. The company had outsourced production of the active ingredient to a long, and ultimately mysterious supply chain. Baxter got the active ingredient from a US company, Scientific Protein Laboratories LLC, which in turn obtained it from a factory in China operated by Changzhou SPL, which in turn was owned by Scientific Protein Laboratories and by Changzhou Techpool Pharmaceutical Co. Changzhou SPL, in turn, got it from several consolidators or wholesalers, who in turn got it from numerous small, unidentified "workshops," which seemed to produce the product in often primitive and unsanitary conditions. None of the stops in the Chinese supply chain had apparently been inspected by the US Food and Drug Administration nor its Chinese counterpart. (See posts here and here.)

- We found out that the Baxter International labelled heparin was contaminated with over-sulfated chondroitin sulfate, a substance not found in nature, but which mimics heparin according to the simple laboratory tests used in the Chinese facilities to check incoming heparin. (See post here.) Further testing revealed that the contamination seemed to have taken place in China prior to the provision of the heparin to Changzhou SPL. (See post here.) It is not clear whether Baxter International or Scientific Protein Laboratories had inspected most of the steps in the supply chain, or even knew what went on there.

- The Baxter and Scientific Protein Laboratories CEOs did not seem aware of where they got the heparin on which the Baxter International label was eventually affixed. But one report in the New York Times alleged that Scientific Protein Laboratories would not pay enough for heparin to satisfy any sources other than the small "workshops."


- Leaders of all organizations involved, Baxter International, Scientific Protein Laboratories, Changzhou SPL, the Chinese government, and the US Food and Drug Administration, and the US Congress assigned blame to each other, but none took individual or organizational responsibility. (See post here.)  Note that SPL was recently bought out and taken private, making its current leadership even less transparent (see post here).  A 2010 inspection of an SPL facility by the FDA revealed ongoing manufacturing problems (see post here).

- Researchers (who turned out to have financial ties to a company which is developing an anti-coagulant drug that could compete with the heparin made by Baxter International) investigated the biological mechanisms by which the contamination of the heparin lead to adverse effects, but no one investigated further how the contamination occurred, or who was responsible. (See post here.)

- Hundreds of lawsuits against Baxter have now been filed, so far without resolution. (See post here.)  Efforts to make documents to be used in these cases public so far have not succeeded (see post here).

- A government report which attracted little attention warned of the dangers of pharmaceutical ingredients made in China and subject to virtually no oversight. (See post here.)

-  Despite requests from the US, the Chinese government did not investigate the production of the heparin that lead to the deaths (see post here.)

-  In February, 2011, a congressional investigation of the case was announced, but results are so far unavailable (see post here.)

-  In June, 2011, a jury returned the first verdict in a civil case about the contaminated heparin, awarding money from Baxter International and Scientific Protein Laboratories to the estate of a man who apparently died due to tainted heparin (see post here).
