Impact of state Medicaid expansion on cross-sector health and social service networks: evidence from a longitudinal cohort study.
This study’s objective was to examine the impact of state Medicaid expansion on the delivery of population health activities in cross-sector health and social services networks. The authors used data measuring the composition of cross-sector population health networks from the 2006-2018 National Longitudinal Survey of Public Health Systems (NALSYS) linked with the Area Health Resource File. They restricted their data to jurisdictions serving populations of 100,000 or more and states that had NALSYS observations across all time periods, resulting in a final sample size of 667. Results indicated that Medicaid expansion was associated with a 2.3 percentage point increase in the density of population health networks. Communities in states with expanded Medicaid experienced significant increases in the participation of local public health, local government, hospitals, nonprofits, insurers, and K-12 schools. Of the organizations with significant increases in expansion communities, nonprofits (7.7 percentage points,), local public health agencies (6.5 percentage points), hospitals (5.8 percentage points), and local government agencies (6.0 percentage points) had the largest gains.

Following uninsured patients through Medicaid expansion: ambulatory care use and diagnosed conditions.
The authors assessed ambulatory care use and diagnosed health conditions among a cohort of community health center (CHC) patients uninsured before enactment of the Affordable Care Act (ACA) and followed them after enactment. They found that, post-ACA, 20.9% of patients remained uninsured, 15.0% gained Medicaid, 12.4% gained other insurance, and 51.7% did not have a visit. The authors concluded that a significant percentage of CHC patients remained uninsured; that many who remained uninsured had diagnosed health conditions; and that one-half continued to have three or more visits to CHCs, which continue to be essential providers for uninsured patients.

Effect of gaining insurance coverage on smoking cessation in community health centers: a cohort study.
This study aimed to determine if uninsured community health center (CHC) patients who gain Medicaid coverage experience greater primary care utilization, receive more cessation medication orders, and achieve higher quit rates, compared to continuously uninsured smokers. It found that newly insured patients had increased odds of quit smoking status over 24 months of follow-up than those who remained uninsured.

Receipt of preventive services after Oregon's randomized Medicaid experiment.
This study examined the three-year impact of Oregon's 2008 randomized Medicaid expansion (the "Oregon Experiment") on receipt of 12 preventive care services in community health centers using electronic health record data. They found that Medicaid coverage significantly increased the odds of receipt of most preventive services. They concluded that rates of preventive services receipt will likely increase as community health center patients gain insurance through Affordable Care Act expansions. They recommended continued effort to increase health insurance coverage in an effort to decrease health disparities in vulnerable populations.
