from other <strong>FDA</strong> consumer protection actions from January 1, 2008,<br />
through December 31, 2011, such as inspections and warning letters, <strong>to</strong><br />
identify which <strong>FDA</strong> actions were associated with a serious AER. We<br />
established a threshold for matching that gave us confidence we were<br />
capturing most of the potential matches and excluding those that were<br />
definitely not a match. The matches were then manually reviewed <strong>to</strong><br />
confirm or reject potential matches. We verified the appropriateness of<br />
this approach with <strong>FDA</strong> officials. To determine the extent <strong>to</strong> which <strong>FDA</strong><br />
has implemented GAO’s 2009 recommendations for enhancing <strong>FDA</strong><br />
oversight of dietary <strong>supplements</strong>, we reviewed relevant laws, planning<br />
documents, and guidance. We also reviewed proposed legislation <strong>to</strong><br />
<strong>expand</strong> <strong>FDA</strong>’s oversight authority for dietary <strong>supplements</strong>. In addition, <strong>to</strong><br />
address all of our objectives, we reviewed relevant studies related <strong>to</strong><br />
dietary <strong>supplements</strong>, adverse event reporting, industry compliance, and<br />
using poison center data for public health surveillance, among others. We<br />
reviewed the methodology for each of these studies and assessed them<br />
for reasonableness in accordance with our objectives. We interviewed<br />
officials from <strong>FDA</strong>’s Center for Food Safety and Applied Nutrition<br />
(CFSAN) who receive and analyze AERs, officials from <strong>FDA</strong>’s Division of<br />
<strong>Dietary</strong> Supplement Programs, officials from <strong>FDA</strong>’s Office of Regula<strong>to</strong>ry<br />
Affairs familiar with the agency’s field operations and regula<strong>to</strong>ry actions,<br />
and officials from <strong>FDA</strong>’s Center for Drug Evaluation and Research. We<br />
also interviewed a wide range of stakeholders, including officials from<br />
HHS’ Centers for Disease Control and Prevention and National Institutes<br />
of Health; and representatives of industry and trade organizations,<br />
consumer advocacy groups, and the American Association of Poison<br />
Control Centers. A more detailed description of our objectives, scope, and<br />
methodology is presented in appendix I.<br />
We conducted this performance audit from December 2011 <strong>to</strong> March<br />
2013 in accordance with generally accepted government auditing<br />
standards. Those standards require that we plan and perform the audit <strong>to</strong><br />
obtain sufficient, appropriate evidence <strong>to</strong> provide a reasonable basis for<br />
our findings and conclusions based on our audit objectives. We believe<br />
that the evidence obtained provides a reasonable basis for our findings<br />
and conclusions based on our audit objectives.<br />
