Data and Analysis


The Division of Data and Analysis includes the Department of Data Management and the Department of Epidemiology and Analysis.

The Division of Data and Analysis performs comprehensive surveillance and analysis of health-related information regarding DoD service members and military-associated populations. To support these efforts, the division operates the following:

  • Defense Medical Surveillance System (DMSS), the DoD's premier epidemiological resource, is a continuously growing longitudinal database of health-related information on service members collected from the time they enter military service until they are no longer eligible for care.
  • The DMSS includes medical encounters (hospitalizations, outpatient visits, immunizations, reportable medical events, health risk appraisals, deployment health assessments), demographic characteristics, and military experiences (deployments, assignments, casualty information).
  • Defense Medical Epidemiology Database (DMED), provides worldwide access to de-identified data from the DMSS. Through a user-friendly interface, authorized users are able to create customized queries of disease and injury rates in active duty populations.
  • Department of Defense Serum Repository (DoDSR), established in 1989, is the world’s largest serum repository with almost 50 million specimens on over 9 million individuals. Originally established for the purpose of storing remaining serum from routine HIV testing, its mission has expanded to include an archive of operational specimens. The availability of serial specimens in the DoDSR that are linked to relevant demographic, occupational, and medical information within the DMSS provides a unique and powerful resource to conduct military medical surveillance, clinical care, and seroepidemiologic investigations.
