Impact of Medicaid expansion on outcomes after abdominal aortic aneurysm repair.
Researchers sought to assess the association between Medicaid expansion and outcomes after abdominal aortic aneurysm repair using HCUP State Inpatient Databases data from 14 states. They examined data on 8995 adult patients under age 65 from both non-expansion states and Medicaid expansion states. The results indicated that Medicaid expansion was associated with decreased in-hospital mortality after abdominal aortic aneurysm repair among all patients, particularly among patients who were either on Medicaid or were uninsured. The researchers concluded that these results provided support for improved access to care for patients undergoing abdominal aortic aneurysm repair through Medicaid expansion.

Medicaid reimbursement rates for primary care services and behavioral health outcomes.
This AHRQ-authored research studied the effects of changing Medicaid reimbursement rates for primary care services on behavioral health outcomes-defined here as mental illness and substance use disorders. The authors applied two-way fixed-effects regressions to survey data specifically designed to measure behavioral health outcomes over the period 2010-2016. They found that higher primary care reimbursement rates reduce mental illness and substance use disorders among non-elderly adult Medicaid enrollees, although they interpreted findings for substance use disorders with some caution as they may be vulnerable to differential pre-trends. Overall, their findings suggest positive spillovers from a policy designed to target primary care services to behavioral health outcomes.
