In a letter to the Government Accountability Office (GAO) dated November 19, 2008, Rep. Joe Barton questioned the adequacy of the FDA's ongoing investigation and evaluation of the recent heparin deaths, casting doubt on whether the FDA in fact has used all available postmarket surveillance tools when determining the likelihood that contaminated heparin caused patient fatalities. Specifically the letter states, “Based on the available information …there is a serious and potentially troubling question about whether FDA availed itself [of] all of its tools to conduct comprehensive surveillance of heparin deaths.” The letter also questions "whether [the] FDA has confounding or conflicting information about Heparin death cases that has not been made public." A copy of this letter is available by clicking here.

As first described in our July 30, 2008 blog, we also have questions concerning the conclusions reached by the FDA as reported to the Chicago Tribune and Nightline. For example, is the FDA investigating or supporting scientific studies to determine whether the contaminate, OSCS, and its resulting symptoms can cause, contribute to, or leave an individual susceptible to other complications leading to death, such as heart failure? (To date, the FDA admits that it has limited knowledge “since the contaminant was only recently discovered” and that all effects are not yet known. (See FDA Questions and Answers, updated 7/3/08.)) Without such studies, the FDA's conclusions may be premature.

Likewise, if the FDA requires additional information to determine whether additional deaths are related, why isn’t this information being gathered or at least requested from the providers or others who filled out the reports to make an adequate determination? For example, as we stated in our July blog, while we have filed multiple adverse-event reports of clients, to date WE HAVE NEVER BEEN CONTACTED BY THE FDA REGARDING THESE REPORTS, NEVER BEEN ADVISED OF THE STATUS OF THEIR INVESTIGATION, OR TOLD THAT ADDITIONAL INFORMATION IS NEEDED.

We have been contacted, however, by many caring lawmakers, journalists, and scientists who have not forgotten the victims of the heparin disaster. We commend and support their ongoing efforts to obtain answers and accountability from the FDA, Baxter and SPL.
