Playing "Kick the FDA" — Risk-free to Players but Hazardous to Public Health
The Food and Drug Administration (FDA) is responsible for regulating $1 trillion worth of consumer products, or 25% of the U.S. consumer economy — the food we eat, the cosmetics we use, the medical devices implanted in our bodies or used in our care, and the drugs we take. It is of grave concern when an agency with such pervasive effects on our lives loses the public's confidence.
Public opinion polls show that confidence in the FDA fell from 80% in the 1970s to 36% in 2006 — ratings usually reserved for tobacco companies and used-car dealers. Much of this deterioration in confidence can be attributed to some high-profile events, ranging from the withdrawal of Vioxx (rofecoxib) to the apparent adulteration of the heparin supply, which many observers have laid largely at the FDA's door — while ignoring the responsibilities of others and the fact that the agency's federal funding is grossly inadequate. Kicking the FDA has become a popular sport for the press and legislators, but by failing to hold others accountable, it puts the public health at serious risk while carrying no personal risk for those who play it.
How did we arrive at this crisis, and what can be done to resolve it? I submit that it is time to demand that the critics assume their own share of responsibility for the recent problems. We need to acknowledge that ensuring the safety and integrity of our food, drugs, cosmetics, and medical devices is primarily the responsibility of manufacturers, with the FDA providing a regulatory framework and oversight. It is also critical that legislators recognize their responsibility to provide the agency with funding that is adequate for it to perform its important functions.
The fundamental problem is that legislators have heaped more and more responsibility on the FDA without appropriately increasing its budget. Between 1988 and 2007, additional FDA responsibilities were imposed by 137 specific statutes, 18 statutes of general applicability, and 14 executive orders.At the same time, the FDA received a 2007 federal appropriation of only $1.57 billion — less than 75% of the budget for the school district in its home county in Maryland, and about the same as the projected cost of the infamous Alaskan "bridge to nowhere." The number of federally appropriated personnel authorized for the FDA has decreased from 9167 in 1994 to 7856 in 2007. And the remaining personnel must work with inadequate information technology: 80% of the FDA's computer servers are more than 5 years old; critical clinical trial records are stored on paper in warehouses, largely inaccessible for analysis; and the information technology budget is about 40% of that for the Centers for Disease Control and Prevention.
Moreover, the agency's work has become vastly more complex, thanks to new science and substantial change in the business environment. Today, industry sources its products from all over the world, seeking the best price wherever it can be obtained. Astonishingly, an estimated 80% of the active pharmaceutical ingredients in U.S. prescription drugs are manufactured overseas, with India and China being the two largest providers. Although the desire to obtain the lowest-cost supplies is understandable, this shift comes with additional responsibilities for manufacturers, who must ensure the quality, chain of custody, and integrity of their supply chain, especially by supervising the manufacturing process in countries whose regulatory environments are more lax than ours.
After a number of deaths and serious adverse reactions occurred in the United States and Germany in association with the administration of heparin, investigators discovered in March that some batches of what should have been pure heparin contained as much as 50% of oversulfated chondroitin sulfate. Since this substance does not occur naturally and mimics heparin in assays, it may have been introduced deliberately, as a cheaper substitute. This incident recalls a 2007 episode in which melamine introduced into pet food resulted in the deaths of a number of animals. Melamine contains a high proportion of nitrogen and was added to livestock feed from China to produce misleading results in assays for protein content, increasing the feed's value. Clearly, manufacturers need to take much stronger steps to ensure the integrity of their supply chain. Such responsibilities go far beyond "meeting regulatory requirements." Neither adulteration of drugs and food products nor the use of lead in toys can be prevented solely by regulators; prevention requires intense supervision by responsible manufacturers.
Unfortunately, the heparin incident has played out in the press and Congress as a failure of the FDA to inspect the Chinese facility, and the agency was quickly condemned for having inspected only 15 facilities in China in 2006. But it is inappropriate and unrealistic to expect the FDA to ensure the integrity of every manufacturer's entire supply chain. If a manufacturer chooses to save money by purchasing raw material from China, then it must bear the additional costs of zealous quality control and oversight in a country with a very limited regulatory system and a fluid commercial structure. U.S. taxpayers should not have to pay to send inspectors to every factory in China to allow industry to obtain cheaper and largely unregulated products there.
It is easier to attack the FDA than to assume one's own share of responsibility. The press, for its part, frequently reports legislators' criticisms of the agency without providing any analysis of their voting records on FDA appropriations. But the bigger scandal is Congress's grossly inadequate funding of the agency, which demands swift and decisive action. No longer should our legislators be able to publicly excoriate FDA employees while ignoring their own complicity. No longer should any of us berate the FDA while failing to acknowledge that we are asking it to do more and more work with fewer and fewer resources. No longer should manufacturers be able to imply that inadequate FDA inspection is an excuse for adulteration of their product during manufacture. We must stop allowing the game of "kick the FDA" to be risk-free to participants. The public's health is at stake, and the time for adequate federal funding of the FDA is now.
攻击FDA远比考虑自己的职责容易得多。媒体频繁报道国会议员对于FDA的批评之词,而不要求其提供任何FDA拨款时的投票记录的分析。但更大的公愤是国会对要求监管局迅速行动,而经费支持严重不足。国会议员们不应再当众批评FDA雇员时而忽略了自己恰恰是同谋犯。我们也不应再斥责FDA时而不承认我们正要求他们以很少的资源做很多的事。生产企业不应再以FDA检查不到位为借口而产品生产过程中掺假。我们必须停止让FDA出局让参与者没有风险的游戏。公众健康正处在生死攸关的境地, 给予FDA充足的经费的时候到了。
