Significant internal and external changes have affected the utilization of healthcare services in the Department of Veterans Affairs (VA). The VA is the largest integrated healthcare system in the U.S., with 9 million enrollees and 6 million users per year. Vanneman and colleagues have spearheaded research on the outcomes of increasing the portion of care currently outsourced to the private sector by the VA, as brought about by the Veterans Choice Act of 2014 and the MISSION Act of 2018.
The group has also worked to project the impacts of the Affordable Care Act for VA enrollees who newly gain Medicaid coverage. One notable finding is that total utilization of outpatient behavioral health services increases after veterans enroll in Medicaid – suggesting that Medicaid is best viewed as a complement rather than a substitute for VA outpatient behavioral health care.
