cost almost $76 million prior <strong>to</strong> the AAPCC discount, and $800,000 after<br />

the discount. However, even with the significant AAPCC discount, access<br />

<strong>to</strong> the data remained more than twice the nearly $400,000 budgeted <strong>to</strong><br />

process and perform surveillance of dietary supplement adverse events in<br />

fiscal year 2011. 42 According <strong>to</strong> CFSAN officials, as of Oc<strong>to</strong>ber 2012,<br />

negotiations with AAPCC had stalled at the CFSAN level. CFSAN officials<br />

said that the cost of accessing the data was a fac<strong>to</strong>r. They also said that,<br />

although negotiations had stalled at the CFSAN level, as of December,<br />

2012, they were ongoing at the department level, but from their<br />

perspective, progress remained difficult.<br />

According <strong>to</strong> CFSAN officials, the greatest challenge for identifying<br />

potential safety concerns from AERs is the small number of AERs that<br />

<strong>FDA</strong> receives related <strong>to</strong> dietary <strong>supplements</strong>. 43 Specifically, these officials<br />

said that it is difficult <strong>to</strong> establish a baseline of doses and responses <strong>to</strong><br />

help the agency detect anomalies that might indicate a potential safety<br />

concern using such a small number of AERs. These officials also said<br />

that they could not determine whether the poison center data would be<br />

<strong>use</strong>ful for such signal detection until they could access it. However,<br />

researchers and the HHS Inspec<strong>to</strong>r General <strong>have</strong> concluded that<br />

accessing poison center data <strong>may</strong> help <strong>FDA</strong> detect and moni<strong>to</strong>r potential<br />

safety concerns. 44 For example, a 2008 study performed in conjunction<br />

with CFSAN and the San Francisco Division of the California Poison<br />

Control System concluded that active surveillance of poison center<br />

reports of dietary supplement adverse events could enable rapid<br />

42 This number does not include resources for CAERS staff, as they perform center-wide<br />

surveillance activities and are budgeted separately. <strong>FDA</strong> officials said that there is also a<br />

concurrent negotiation effort underway at the department level <strong>to</strong> obtain access <strong>to</strong> AAPCC<br />

data for multiple HHS components, including CDC and <strong>FDA</strong>.<br />

43 <strong>FDA</strong> received more than 1.8 million AERs related <strong>to</strong> prescription drugs from 2008 <strong>to</strong><br />

2010, in comparison <strong>to</strong> the 3,827 <strong>FDA</strong> received related <strong>to</strong> dietary <strong>supplements</strong> from 2008<br />

<strong>to</strong> 2010. Prescription drug AERs include those that are submitted directly <strong>to</strong> <strong>FDA</strong> and four<br />

types of AERs submitted <strong>to</strong> <strong>FDA</strong> by manufacturers for health problems, depending on the<br />

nature of the health problem, whether the health problem is described as a potential side<br />

effect in the product labeling, and the type of product.<br />
