Because of VA's long history in disaster preparedness, and the crucial role VA providers will play, the VA medical system has the potential to make an enormous difference in outcomes following a bioterror attack or infectious outbreak. A 2002 AHRQ report reviewed 60 studies and found that very few bioterrorism preparedness training programs were rigorously evaluated. Our project was the first effort to formally test and implement a bioterrorism preparedness intervention in the VA healthcare system. Because Internet-delivered interventions have the potential for wide dissemination, we used the Internet to implement the Intervention.
