Assessing Health Outcomes Among Veterans of Project SHAD (Shipboard Hazard and Defense) Preface When the secret Project Shipboard Hazard and Defense (SHAD) testing program was made public in 2000, veterans reasonably wondered what impact their involvement in the testing might have had on their health. Following the release of the first Institute of Medicine (IOM) SHAD report in 2007, Congress requested that the IOM undertake a new epidemiological study of the potential long-term health effects of participation in the SHAD testing. Our committee, with expertise in epidemiology, occupational health, biostatistics, exposure assessment, toxicology, and Vietnam veterans’ health issues, was convened to examine this question, a role the committee took very seriously. Our careful review of published scientific literature on the agents, simulants, tracers, and decontaminants used in the tests, led us to formulate hypotheses on health effects that might be associated with exposure to six of these substances. We also undertook exploratory analyses to ensure that unanticipated associations would not be overlooked. Our task was challenging because of the passage of time since the tests, and because many of the documents related to the tests remain classified. Our requests for declassification of additional documents were not approved. Using the limited information available in redacted reports on these tests, the committee evaluated exposure opportunities that test participants may have had. The study faced other challenges as well. Protecting the security of the data used in the study was, of course, of high importance to the committee and to the Department of Veterans Affairs (VA). Meeting those obligations made it necessary to work within the VA information technology system, and this posed a series of requirements that significantly
