Data Linkages

DoDSR inventory data and related information are stored in an Oracle database referred to as the Defense Medical Surveillance System (DMSS), which serves as the "sole link" to the DoDSR inventory. Serum specimens are identified by a unique specimen identification number, which for the majority of specimens are linked to the Social Security Number of the donor, and the date the specimen was obtained.

In addition to inventory data, DMSS also integrates select medical outcomes data available through the Military Health System (MHS), including International Classification of Diseases, 9th Edition, Clinical Modification (ICD-9CM) diagnosis codes, Current Procedural Terminology (CPT) codes, and other pertinent administrating data from inpatient and outpatient encountered provided directly by the MHS or through Tricare managed care services.

Active duty component service members (unlike service members in the Reserve components), are entitled to free (or nearly free) health care for the duration of their military service, the details of which are captured electronically in DMSS. The active duty component thus constitutes a cohort where health events can be assessed longitudinally with minimal ascertainment bias. Over half of the specimens in the DoDSR are traceable to service members who have been on active duty, and 75% of active duty service members have provided three or more longitudinal specimens.

Limited additional health and personnel data linked to DoDSR specimens include records of immunizations, overseas deployments, military assignment data, and records from pre- and post-deployment health assessments.
