In addition, breach of confidentiality is a potential risk due to the use of sensitive private information. The results of this study may be published or presented but the participant's identity and records will not be revealed unless required by Federal Law. A Federal Law allows the U.S. Food and Drug Administration, Office for Human Research Protections, Government Accountability Office and other Federal agencies, the Research and Development Committee, representatives of USAMRMC, Henry M. Jackson Foundation, and/or the Institutional Review Board (IRB)/Human Studies Subcommittee of the VA Medical Center or University of Minnesota to review records. Because of the need for these inspections, absolute confidentiality cannot be guaranteed. However, every effort would be made to minimize these risks by providing the participant with a unique numerical identifier at the beginning of the study in order to protect their actual identification and maintain complete confidentiality.
