Studies

Welcome to the Military Health System Studies Inventory Tool (MSIT). Military Health System (MHS) data are used by Department of Defense, Veterans Administration, and academic health professionals and scientists to implement health care studies. These studies reflect the MHS interest to rigorously assess and improve our beneficiaries’ access to the high quality health care services they need. Additionally, these studies are frequently used to develop or improve MHS policy and often adopt useful, relevant comparisons to the national health care experience.

The MSIT allows easy review of recent studies that are either conducted or sponsored by the MHS, or accomplished using datasets developed or maintained by the Defense Health Agency for administrative, operational, or research purposes. The studies within this website represent important contributions of the MHS to the national health care dialogue and reflect our capacity to tackle the challenging issues needed to support evidence-informed health policy. Thank you for your interest in them.

Update: Routine screening for antibodies to human immunodeficiency virus, civilian applicants for U.S. military service and U.S. Armed Forces, active and reserve components, January 2009-June 2014.

Study

Abstract

This report contains an update through June 2014 of the results of routine screening for antibodies to the human immunodeficiency virus (HIV) among civilian applicants for military service and among members of the active and reserve components of the U.S. Armed Forces. Seroprevalences among civilian applicants in 2013 and the first half of 2014 (0.19 and 0.15 per 1,000 tested, respectively) were markedly lower than in 2012 (0.27 per 1,000 tested). In nearly every component of every service, seroprevalences in 2013 and 2014 were either similar or lower than in prior years; however, in the Army National Guard, seroprevalences increased each year and approximately doubled from 2010 (0.18 per 1,000 tested) to 2013-2014 (0.35-0.41 per 1,000 tested). Among active and reserve component service members, seroprevalences continue to be higher among Army and Navy members and males than their respective counterparts.

Assessing functional impairment in a working military population: the Walter Reed functional impairment scale.

Study

Abstract

Measurement of functional impairment is a priority for the military and other professional work groups routinely exposed to stressful traumatic events as part of their occupation. Standard measures of impairment used in general or chronically ill populations contain many items not suitable for these populations, and include mental health symptoms items that are not true measures of functioning. We created a new, 14-item scale-the Walter Reed Functional Impairment Scale-to assess functioning in 4 domains (physical, occupational, social, and personal). We asked 3,380 soldiers how much difficulty they currently have in each of the 4 domains on a 5-point scale. Behaviorally based psychosocial and occupational performance measures and general health questions were used to validate the scale. The utility of the scale was assessed against clinical measures of psychopathology and physical health (depression, posttraumatic stress disorder [PTSD], general health, generalized physical symptoms). We utilized Cronbach's alpha, item response theory, and the score test for trend to establish consistency of items and the validity of the scale. The scale exhibited excellent reliability (Cronbach's α= 0.92) and validity. The individual items and quartiles of sum scores were strongly correlated with negative occupational and social performance, and the utility of the scale was demonstrated by strong correlations with depression, PTSD, and high levels of generalized physical symptoms. This scale exhibits excellent psychometric properties in this sample of U.S. soldiers and, pending future research, is likely to have utility for other healthy occupational groups.
