The impacts of the 340B Program on health care quality for low-income patients.
This study’s objective was to assess the effects of hospital 340B eligibility on quality of inpatient care provided to Medicaid and uninsured patients and for all patients. HCUP State Inpatient Data, Hospital Cost Reporting Information System Data, Office of Pharmacy Affairs Information System Data, and the American Hospital Association Annual Survey were all used to extract inpatient data from general acute care hospitals from 2008 to 2014 in 15 states. Data was linked on hospital 340B eligibility and participation. The authors did not find discontinuities in inpatient care quality across the Program eligibility threshold for Medicaid and uninsured patients; specifically, on all-cause mortality, 30-day readmission rates, or other measures. Among insured and non-Medicaid patients, they found discontinuities for acute myocardial infarction and postoperative sepsis mortality.

Are North Carolina clinicians delivering opioid use disorder treatment to Medicaid beneficiaries?
This study’s goal was to inform efforts to increase prescriptions of medications for opioid use disorder (MOUD) among Medicaid beneficiaries. A retrospective study of North Carolina licensed physicians, physician assistants, and nurse practitioners was conducted to estimate Medicaid participation prevalence among clinicians authorized to prescribe buprenorphine and to estimate the association between clinician characteristics and OUD care delivery to Medicaid beneficiaries. Outcomes looked for were indicators of any Medicaid professional claims and Medicaid claims data for buprenorphine and naltrexone. Licensure data from 2018 was merged with 2019 US Drug Enforcement Administration to identify clinicians who used the DEA waiver required to prescribe buprenorphine (n = 1714). Services by waivered clinicians to Medicare beneficiaries ranged from 67% of behavioral health clinicians to 82.9% of specialist physicians. Prevalence of prescribing buprenorphine to Medicaid beneficiaries ranged from 30.3% among specialist physicians to 51.6% among behavioral health clinicians.

Increasing Medicaid's stagnant asset test for people eligible for Medicare and Medicaid will help vulnerable seniors.
Researchers examined states' income and asset tests for full-benefit Medicaid during the period 2006-18 and examined how alternative asset tests would affect eligibility for community-dwelling Medicare beneficiaries ages sixty-five and older. They found that increasing asset limits would lessen restrictions on Medicaid eligibility that arise from stagnant asset tests, broadening eligibility for certain low-income Medicare beneficiaries and allowing them to retain higher, yet still modest, savings.

FQHC designation and safety net patient revenue associated with primary care practice capabilities for access and quality.
Researchers assessed capabilities around access to and quality of care among primary care practices serving a high share of Medicaid and uninsured patients compared to practices serving a low share of these patients. Data from the National Survey of Healthcare Organizations and Systems was analyzed. They found that federally qualified health centers were more likely than other types of primary care practices (both safety net practices and other practices) to possess capabilities related to access and quality. However, safety net practices were less likely than non-safety net practices to possess health information technology capabilities.

Antipsychotic use among youth in foster care enrolled in a specialized managed care organization intervention.
This study examined a multimodal antipsychotic intervention implemented by a specialized Medicaid managed care organization (MMCO) for youths in foster care with routine mental health screening, health passports, elective psychiatric consultation line, and retrospective drug utilization reviews to determine whether this multimodal intervention significantly reduced antipsychotic dispensing for youths with conditions without US Food and Drug Administration (FDA)-approved indications. Findings showed that MMCO implementation significantly reduced antipsychotic medications without FDA-indicated conditions prescribed to youths, while not significantly affecting antipsychotic medications prescribed to youths with FDA-indicated conditions.

States with medically needy pathways: differences in long-term and temporary Medicaid entry for low-income Medicare beneficiaries.
Between January 2009 and June 2010, states with medically needy pathways had a higher percentage of low-income beneficiaries join Medicaid than states without such programs. However, among new full Medicaid participants, living in a state with a medically needy pathway was associated with an increase in the probability of switching to partial Medicaid and an increase in the probability of exiting Medicaid within 12 months. Alternative strategies for protecting low-income Medicare beneficiaries' access to care could provide more stable coverage.

Impact of social needs case management on use of medical and behavioral health services: secondary analysis of a randomized controlled trial.
This research letter describes a secondary analysis that was conducted of a randomized encouragement study that assigned Medicaid beneficiaries with high risk for acute care use to social needs case management or to be administratively observed in the control group from August 2017 through December 2018. These services connect patients to resources such as food assistance, housing, transportation, or income benefits in addition to facilitating access to health care and behavioral health services. The study group included adults 18 years or older, who are residents of Contra Costa County in California, and enrolled in full-scope Medicaid. The case management enrollees were assigned to a case manager who assessed their needs, created a patient-centered care plan, and provided ongoing support including community resource referrals, coordination with primary care providers, and collaboration on applications for public benefits. Case managers had diverse backgrounds and included public health nurses, social workers, substance misuse counselors, mental health clinicians, homeless service specialists, and community health workers. Case management was offered either in-person or by remote telephonic services for 1 year. About 40% (n = 8577) of enrolled patients used the services. There were 21,422 intervention group enrollments and 22,839 in the weighted control group. The intervention group had significantly higher rates of primary care visits compared with the control group. No differences were found between the treatment groups for specialty care visits, behavioral health visits, psychiatric emergency visits, or jail intakes.

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.

Association of state policies with Medicaid disenrollment among low-income Medicare beneficiaries.
This study examined the role that state policies play in Medicaid disenrollment among low-income Medicare beneficiaries. Medicaid disenrollment among fee-for-service Medicare beneficiaries was examined for the period 2012-2016. During that period, 18.2% of beneficiaries disenrolled for reasons other than death. Disenrollment was 24% lower in states that automatically enrolled recipients of the Supplemental Security Income program in full Medicaid, 33% lower in states with more generous provider payment policies, and 37% lower in states with less restrictive asset limits for partial Medicaid.

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.

Substance use, homelessness, mental illness and Medicaid coverage: a set-up for high emergency department utilization.
The objective of this study was to identify characteristics unique to patients with psychiatric illness who are frequent emergency department (ED) users for mental health care. The authors suggest that understanding unique features of this population could lead to better care and lower healthcare costs. The authors concluded that patients with substance use disorders, homelessness and public healthcare coverage were more likely to be frequent users of EDs for mental illness.

Differences in Medicaid antipsychotic medication measures among children with SSI, foster care, and income-based aid.
This study examined the application of 6 quality measures for antipsychotic medication prescribing in children and adolescents receiving Medicaid. While indicators of overuse were more common in those with Supplemental Security Income and foster care groups, access to follow-up, metabolic monitoring, and psychosocial services was somewhat better for these children. However, substantial quality shortfalls existed for all groups, particularly metabolic screening and monitoring.

Household immigration status had differential impact on Medicaid enrollment in expansion and nonexpansion states.
This study identified households that likely included undocumented immigrants and then examined whether gains in health care coverage due to the expansion of Medicaid eligibility under the Affordable Care Act (ACA) were dampened for eligible people living in households with mixed immigration status. It found that coverage gains were significantly lower for people in mixed-status households relative to those in non-mixed-status households in nonexpansion states.

Medicaid disenrollment patterns among children coming into contact with child welfare agencies.
The authors examined retention of Medicaid coverage over time for children in the child welfare system. Using Medicaid claims files from 36 states, they found that half retained Medicaid coverage across 4 years of follow up, with most disenrollments happening in year 4. They recommend finding ways to promote entry of child welfare-involved children into health insurance coverage in order to assure services.

Stakeholder assessment of comparative effectiveness research needs for Medicaid populations.
Because children, pregnant women and people with mental illness have generally been underrepresented in research discussions, comparative effectiveness rsearch (CER) questions for these groups may be understudied. To address this problem, AHRQ commissioned a team to work with Medicaid Medical Directors and other stakeholders to identify relevant CER questions. Through an iterative process of topic identification and refinement, they developed relevant, feasible and actionable questions based on issues affecting Medicaid programs nationwide.

Foster care, externalizing disorders, and antipsychotic use among Medicaid-enrolled youths.
The researchers investigated the extent to which clinical diagnoses of externalizing disorders explain higher rates of antipsychotic use by foster care youths. They found that foster care youths had higher rates of externalizing disorders than the comparison group and greater antipsychotic use. Foster care remained a significant predictor of antipsychotic use after control for demographic and diagnostic covariates.
