North Carolina Medicaid recipient management lock-in program: the pharmacist's perspective.
The objectives of this study were (a) evaluate pharmacists’ perceptions of the implementation of the North Carolina (NC) recipient management lock-in program (MLIP) and (b) determine how the beliefs and attitudes of pharmacists could promote or inhibit its success. It concluded that, although possible improvements were identified, the NC MLIP has strong potential for success as it utilizes pharmacists’ medication gate-keeping role, while minimizing the effort required for successful implementation.

Estimating demand for care after a Medicaid expansion: lessons from Oregon.
In order to estimate how the Affordable Care Act's Medicaid expansions will affect demand for services, the authors measured ambulatory care utilization among adult patients who gained insurance during Oregon's 2008 Medicaid expansion. They found that, in comparisons of the pre- and postcoverage periods, the mean annual encounters among persons who gained insurance increased 22% to 35%, but declined in the comparison groups.

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.

Predictors of medication-related problems among Medicaid patients participating in a pharmacist-provided telephonic medication therapy management program.
The objective of this study was to identify predictors of medication-related problems (MRPs) among Medicaid patients participating in a telephonic medication therapy management (MTM) program. The analysis of study results supports the relative importance of number of medications as a predictor of MRPs in the Medicaid population and identifies other predictors.

Reducing hospital readmissions among Medicaid patients: a review of the literature.
This review aims to identify factors related to readmissions that are unique to Medicaid populations to inform efforts to reduce Medicaid readmissions. It concluded that much of the Medicaid readmissions literature focuses on patients with mental health or substance abuse issues, who are often high utilizers of health care within the Medicaid population.

The effect of pre-Affordable Care Act (ACA) Medicaid eligibility expansion in New York State on access to specialty surgical care.
Using the natural experiment of Medicaid expansion in New York (NY) State in October 2001, the study investigators examined whether Medicaid expansion increased access to common musculoskeletal procedures for Medicaid beneficiaries. They concluded that Medicaid expansion in NY State significantly improved access to common musculoskeletal procedures for Medicaid beneficiaries.

Using Medicaid and CHIP claims data to support pediatric quality measurement: lessons from 3 centers of excellence in measure development.
The investigators sought to explore the claims data-related issues relevant to quality measure development for Medicaid and the Children's Health Insurance Program (CHIP), illustrating the challenges encountered and solutions developed around 3 distinct performance measure topics: care coordination for children with complex needs, quality of care for high-prevalence conditions, and hospital readmissions. Their three Centers of Excellence in pediatric quality measurement used innovative methods to develop algorithms that use Medicaid claims data to identify children with complex needs; to overcome some shortcomings of existing data for measuring quality of care for common conditions such as otitis media; and to identify readmissions after hospitalizations for lower respiratory infections.

Medicaid admissions and readmissions: understanding the prevalence, payment, and most common diagnoses.
The authors characterized acute care hospital admissions and thirty-day readmissions in the Medicaid population through a retrospective analysis in nineteen states. They found that Medicaid readmissions were both prevalent and costly, and that they represented 12.5 percent of Medicaid payments for all hospitalizations, with the most prevalent diagnostic categories being mental and behavioral disorders and diagnoses related to pregnancy, childbirth, and their complications.

Rehospitalization during the first year of life by insurance status.
The authors assessed the association of insurance status on infant rehospitalization in a population-based setting. They found that Medicaid coverage and being uninsured were strong predictors of rehospitalizations, with Medicaid bearing a disproportionate share of the economic burden. Normal birth weight infants had the lowest risk. They further found that jaundice and acute bronchiolitis were the leading causes of rehospitalization within 30 days and 1 year, respectively.

Agreement of Medicaid claims and electronic health records for assessing preventive care quality among adults.
The researchers sought to compare the agreement of electronic health records (EHR) data versus Medicaid claims data in documenting adult preventive care. For services performed in the primary care setting, EHR data compared favorably to Medicaid claims in documenting the percentage of patients with service receipt; services that were referred out were less frequently observed in the EHR.

Validity of maternal and infant outcomes within nationwide Medicaid data.
The researchers aimed to assess the validity of preeclampsia, congenital cardiac malformations, and persistent pulmonary hypertension of the newborn diagnoses in the U.S. Medicaid Analytic eXtract (MAX), a database that may be useful for perinatal research. The positive predictive values were conservative, particularly when restricting to infants not transferred to another facility shortly after birth because only records from a single hospitalization were reviewed.

Adults in the income range for the Affordable Care Act's Medicaid expansion are healthier than pre-ACA enrollees.
The investigators used MEPS data to compare nondisabled adults enrolled in Medicaid prior to the ACA with two other groups: adults who were eligible for Medicaid but not enrolled in it, and adults who were in the income range for the ACA's Medicaid expansion and thus newly eligible for coverage. They found that both the newly eligible and those eligible before the ACA but not enrolled were healthier on several measures than pre-ACA enrollees. They concluded that by expanding Medicaid eligibility, states could provide coverage to millions of healthier adults as well as to millions who have chronic conditions and who need care.

Assessing the chiral switch: approval and use of single-enantiomer drugs, 2001 to 2011.
The researchers studied the prevalence of chiral switching in the United States over the past decade, including trends in use of, and expenditures on these products in Medicaid. They found that recently approved single-enantiomer drugs showed no evidence of superior efficacy over the older racemic precursors in the pivotal trials leading to their approval.

Moving for Medicaid? Recent eligibility expansions did not induce migration from other states.
This study used 26 measures of low value services to examine service use and associated spending detected by these measures in Medicaid. In the six categories of care measured, services detected by a limited number of measures of low-value care constituted modest proportions of overall spending (2.7 percent) but affected 42 percent of beneficiaries.

New evidence on the Affordable Care Act: coverage impacts of early Medicaid expansions.
Since 2010 California, Connecticut, Minnesota, and Washington, D.C., have taken advantage of the Affordable Care Act’s option to expand coverage earlier to a portion of low-income childless adults. The researchers present new data on these expansions focusing on several questions including the extent to which childless adults’ new enrollment in Medicaid result from extending coverage to uninsured people as opposed to replacing private coverage.
