Estimating the impact of insurance expansion on colorectal cancer and related costs in North Carolina: a population-level simulation analysis.
Researchers used microsimulation to estimate the health and financial effects of insurance expansion and reduction scenarios in North Carolina (NC) for colorectal cancer screening (CRC). The full lifetime of a simulated population of residents age-eligible for CRC screening (aged 50-75) during a 5-year period were simulated. Findings indicate that the estimated cost savings--balancing increased CRC screening/testing costs against decreased cancer treatment costs--were approximately $30 M and $970 M for Medicaid expansion and Medicare-for-all scenarios, respectively, compared to status quo. The researchers concluded that insurance expansion will likely improve CRC screening both overall and in underserved populations while saving money, with the largest savings realized by Medicare.

Prescription opioid use patterns, use disorder diagnoses and addiction treatment receipt after the 2014 Medicaid expansion in Oregon.
This study compared the prevalence of receipt of opioid prescriptions and opioid use disorder (OUD), along with time from OUD diagnosis to medication-assisted treatment (MAT) receipt between Oregon residents who had been continuously insured by Medicaid, were newly insured after Medicaid expansion in 2014 or returned to Medicaid coverage after expansion.

Where do Oregon Medicaid Enrollees seek outpatient care post-Affordable Care Act Medicaid expansion?
The purpose of this study was to understand where Oregon Medicaid beneficiaries sought care after the Patient Protection and Affordable Care Act Medicaid expansion (emergency department, primary care, or specialist) and the interaction between primary care establishment and outpatient care utilization. Results showed that most newly and returning-insured Medicaid enrollees sought primary care rather than emergency department services and most became established with primary care, suggesting that both insurance and primary care continuity play a role in where patients seek health care services.

The impact of Medicaid expansion on continuous enrollment: a two-state analysis.
Researchers assessed the impact of Medicaid expansion under the Affordable Care Act on continuity of Medicaid coverage among those enrolled prior to expansion. Comparing Colorado to Utah, they found that, following Medicaid expansion, enrollees in Colorado gained an additional 2 months of coverage over two years of follow-up and were 16 percentage points less likely to experience a coverage disruption in a given year relative to enrollees in Utah. They concluded that increasing Medicaid eligibility levels appeared to be an effective strategy with important implications for other states that are considering Medicaid expansion.

Changes in hospital service demand, cost, and patient illness severity following health reform.
This study examined the effects of expanded Medicaid coverage and the health insurance exchange on the number of hospital inpatient and emergency department (ED) utilization rates, cost, and patient illness severity. There was a significant drop in uninsured inpatient discharges and ED visits in states where Medicaid was expanded. For all by young females, uninsured inpatient discharge rates fell by 39% or greater. In nonexpansion states, the rates remained unchanged or increased slightly. Changes in all-payer and private insurance rates were not as dramatic, as was inpatient costs per discharge and all-payer inpatient costs.

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.

Study protocol: a mixed-methods study of women's healthcare in the safety net after Affordable Care Act implementation - EVERYWOMAN.
In this paper, the authors describe a 5-year, mixed-methods study comparing women's contraceptive, preventive, prenatal and postpartum care before and after ACA implementation and between Medicaid expansion and non-expansion states. They conclude that the findings will be relevant to policy and practice, informing efforts that enhance the provision of timely, evidence-based reproductive care, to improve health outcomes, and to reduce disparities among women. Patient, provider and practice-level interviews will serve to contextualize their findings and to develop subsequent studies and interventions to support women's healthcare provision in community health center settings.

Colorectal cancer screening in newly insured Medicaid members: a review of concurrent federal and state policies.
The goal of this study was to determine the impact of national and state policies enacted to increase access to Medicaid and to promote colorectal cancer (CRC) screening on newly enrolled, age-eligible Oregon Medicaid beneficiaries. 2010 - 2015 Oregon Medicaid claims data was used to conduct a cohort analysis of enrollees who turned 50 and became age-eligible for CRC screening. Individuals newly enrolled in Medicaid in 2013 or 2014 were more likely to initiate CRC screening than those enrolled by 2010, associated with the timing of policies such as Medicaid expansion and federal matching for preventive services. A primary care visit during the calendar year, one or more chronic conditions, and Hispanic ethnicity were also associated with CRC screening initiation.

Access to care among Medicaid and uninsured patients in community health centers after the Affordable Care Act.
This study assessed differences in access to care for patients at Community Health Centers (CHCs) between those with continuous Medicaid coverage and those with gaps in insurance coverage, in order to examine the role of Medicaid coverage on care patterns for those with available safety net care. Data on adult patients with continuous Medicaid coverage and those with a period without insurance coverage in the last 12 months was gathered from the 2014 Health Center Patient Survey. Reported need for various types of care, prescription drugs, or referrals to care outside of the CHC, and reports of being delayed or unable to get needed care by insurance status were examined. Patients with insurance gaps were significantly more likely to report having difficulty obtaining medical care, prescription drugs, dental care, and completing outside referrals. The authors conclude that continuous Medicaid coverage appears to mitigate barriers to care for CHC patients when compared to those who have intermittent or no insurance coverage. Policies that increase disruptions in coverage could adversely impact access to care, even among those with available safety net care.

Medicaid coverage and continuity for juvenile justice-involved youth.
This retrospective cohort study examined Medicaid coverage and continuity for youth with varying levels of justice system involvement and the impact of a policy change allowing Medicaid suspension, rather than termination. The study highlighted the importance of maximizing opportunities to keep youth enrolled, as gaps in coverage likely affect juveniles' access to physical, mental, and behavioral health care.
