In May 2012, Senator Grassley asked the University of Alabama Hospital to provide information regarding its policies associated with 340B patients. The request was prompted by a February 2011 presentation in which a Senior Pharmacist at the hospital discussed changing treatment protocol and location in order to maximize saving opportunities associated with the 340B drug discount program. In July, Representatives Joseph R. Pitts and Bill Cassidy, citing oversight problems outlined in a September 2011 Government Accountability Office ("GAO") report, requested that the Health Resources and Services Administration issue an updated definition of "340B patient" in order to curb any misuse of the program. The GAO report identified the risk of improper purchase of 340B drugs since the program is increasingly used in settings that serve both 340B and non-340B eligible patients.
