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.

Abstract

OBJECTIVES: The aim of this study was to assess the risk of incident rheumatological diagnoses (RD) associated with self-reported diarrhoea and vomiting during a first-time deployment to Iraq or Afghanistan. Such an association would provide evidence that RD in this population may include individuals with reactive arthritis (ReA) from deployment-related infectious ...

A prospective cohort study of treatment decision-making for prostate cancer following participation in a multidisciplinary clinic.

Study

Abstract

BACKGROUND: Patients diagnosed with prostate cancer (PCa) are presented with several treatment options of similar efficacy but varying side effects.
