Twelve-month health care use and mortality in commercially insured young people with incident psychosis in the United States.
This study assessed 12-month mortality and patterns of outpatient and inpatient treatment among young people experiencing an incident episode of psychosis in the United States. The hugely elevated mortality observed, when compared to the general population, underscores that young people experiencing psychosis warrant intensive clinical attention-yet the researchers found low rates of pharmacotherapy and limited use of psychosocial treatment.

The Mental Health Parity and Addiction Equity Act evaluation study: impact on specialty behavioral healthcare utilization and spending among enrollees with substance use disorders.
The purpose of this study was to determine whether Mental Health Parity and Addiction Equity Act (MHPAEA) was associated with increased behavioral health expenditures and utilization among a population with substance use disorder (SUD) diagnoses. The investigators found that MHPAEA was associated with modest increases in total, plan, and patient out-of-pocket spending and outpatient and inpatient utilization.

Changes in utilization and health among low-income adults after Medicaid expansion or expanded private insurance.
The researchers assessed changes in access to care, utilization, and self-reported health among low-income adults in 3 states taking alternative approaches to the ACA. They concluded that in the second year of expansion, Kentucky's Medicaid program and Arkansas's private option were associated with significant increases in outpatient utilization, preventive care, and improved health care quality; reductions in emergency department use; and improved self-reported health.

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.

Racial and ethnic disparities in health care access and utilization under the Affordable Care Act.
The objective of this study was to examine racial and ethnic disparities in health care access and utilization after the Affordable Care Act (ACA) health insurance mandate was fully implemented in 2014. Its results demonstrate that racial and ethnic disparities in access have been reduced significantly during the initial years of the ACA implementation that expanded access and mandated that individuals obtain health insurance.

Do Medicaid benefit expansions have teeth? The effect of Medicaid adult dental coverage on the use of dental services and oral health.
This article examines the effect of Medicaid adult dental coverage on use of dental care and dental health outcomes using state-level variation in dental coverage during 2000-2012. Its findings imply that dental coverage is associated with an increase in the likelihood of a recent dental visit, with the size of the effect increasing with Medicaid payment rates to dentists, and a reduction in the likelihood of untreated dental caries.

Coverage and care consequences for families in which children have mixed eligibility for public insurance.
The researchers used data from the Medical Expenditure Panel Survey (MEPS) Household Component for 2001–12 to examine insurance coverage, access to care, and health care use for eligible children in families with mixed eligible siblings compared to those in families where all siblings were eligible for one program. They found that mixed eligibility has a significant dampening effect for eligible children.

Impact of subsidized health insurance coverage on emergency department utilization by low-income adults in Massachusetts.
The authors aimed to estimate the change in emergency department (ED) utilization per individual among a cohort who qualified for subsidized health insurance following the Massachusetts health care reform. They concluded that expanding subsidized health insurance did not uniformly change ED utilization for all newly insured low-income adults in Massachusetts.

Effect of insurance expansion on utilization of inpatient surgery.
The researchers examined the differential effect of the Massachusetts insurance expansion on the use of discretionary vs. nondiscretionary surgical procedures. They found that discretionary surgery increased 9.3 percent while nondiscretionary surgery decreased by 4.5 percent. The greatest increase in discretionary surgery was observed for nonwhite participants.

How do coverage policies influence practice patterns, safety, and cost of initial lumbar fusion surgery? A population-based comparison of workers' compensation systems.
In response to increasing use of lumbar fusion for improving back pain, despite unclear efficacy, particularly among injured workers, this study compared the use of complex fusion techniques, adverse outcomes within 3 months, and costs for California and Washington State with workers’ compensation policies that differed in their coverage restrictions. The researchers found that California’s broader coverage policy was associated with more aggressive practice, higher rates of reoperation, readmission and other complications.

Use of intensive care services and associated hospital mortality after Massachusetts healthcare reform.
This study examined the impact of increased insurance coverage on intensive care unit (ICU) usage and mortality in Massachusetts where health insurance reform had expanded coverage. It found that reform was not associated with either significant changes in ICU use or changed hospital mortality for ICU patients.

High utilizers of emergency health services in a population-based cohort of homeless adults.
This study identified predictors of frequent emergency department (ED) use among a population-based sample of homeless adults in Toronto, Ontario. It found that among homeless adults with universal health insurance, a small subgroup accounted for the majority of visits to emergency services. Frequent use was driven by multiple predisposing, enabling, and need factors.

Preventive services for adults: how have differences across subgroups changed over the past decade?
This study uses MEPS data to track changes over time in the distribution of preventive services use across groups defined by poverty status, race/ethnicity, insurance coverage, Census region, and urbanicity. The analysis found that differences across subgroups tended to persist over time, with some of the largest gaps between adults with and without coverage. Regional differences persisted or widened over the study period.
