About the Center for health services research



The Center for Health Services Research supports the readiness of America’s Warfighter and improved health outcomes for the military community by building capacity throughout the Military Health System (MHS) to conduct health services research that support MHS goals, DoD’s mission, and the national security strategy.


By the end of CY2027, the Center for Health Services Research will be nationally recognized as the leader in MHS Health Services Research.  We will produce actionable, outcomes-based policy recommendations and direct support that will improve health outcomes throughout the MHS and will be instrumental in supporting the MHS as it reimagines current care models and the healthcare experience throughout the continuum of care.
