Product reformulation and nutritional improvements after new competitive food standards in schools.
In 2012, Massachusetts enacted school competitive food and beverage standards similar to national Smart Snacks. These standards aim to improve the nutritional quality of competitive snacks. This study assessed whether products were reformulated after standards were implemented; the availability of reformulated products outside schools; and whether compliance with the standards improved the nutrient composition of competitive snacks. The investigators concluded that Massachusetts' law was effective in improving the nutritional content of snacks and product reformulation helped schools adhere to the law.

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.

Dementia and motor vehicle crash hospitalizations: role of physician reporting laws.
This study sought to determine the effect of physician reporting laws and state licensing requirements on crash hospitalizations among drivers with dementia. It concluded that physician reporting laws, mandated or legally protected, were not associated with a lower likelihood of dementia among crash hospitalized drivers. Vision testing at in-person renewal and in-person renewal requirements were significantly related with a lower prevalence of dementia in hospitalized older drivers.

Medicaid becomes the first third-party payer to cover passive remote monitoring for home care: policy analysis.
This study examined passive remote monitoring technologies in state Medicaid programs. Its goals were to identify which states allowed location tracking, sensor systems, and cameras, what policies were in place to track usage, what implementation processes and program monitoring mechanisms were in place, and what related insights Medicaid program stakeholders would like to learn. Interviews were conducted with state, federal, and managed care organization (MCO) Medicaid program stakeholders about the use of these technologies in state waivers that served community-dwelling older adults in 15 states. While two-thirds of the states covered location tracking and activity-monitoring sensors and one-third covered cameras, only 3 states had specific service categories that allowed tracking of when they pay for these technologies. The authors conclude that technologies that have great potential to alter the way older adults receive supportive services are often used without research on their use, social or ethical implications, or outcomes. New service categories are needed to enable oversight, and more interaction between policymakers and researchers in this field would aid in the prioritization of research aims to inform practice.

A concentric neighborhood solution to disparity in liver access that contains current UNOS districts.
Policymakers are deliberating policy reforms to reduce geographic disparity in liver allocation. This study conducted simulations comparing current allocation with the neighborhoods and sharing policies. The study concluded that the current 11 districts can be adapted systematically by adding neighboring donor service areas (DSAs) to improve geographic disparity, mortality, and airplane travel distance. Modifications to Share 35 and Share 15 policies result in further improvements.

Association of coded severity with readmission reduction after the hospital readmissions reduction program.
This research letter describes a study which examined coding by hospitals used to determine rates of readmission under the Hospital Readmission Reduction Program (HRRP). Hospitals who go above a certain rate are subject to financial penalties for 3 targed medical conditions. It was determined that hospitals have begun to change their coding to show increased severity of illness in many of those readmissions. Data came from discharges from the Medicare Provider Analysis and review file between 2008 and 2014. Researchers compared coding severity levels from before HRRP was implemented and post April 1, 2010 when it began.

Paid maternity leave in the United States: associations with maternal and infant health.
Using data from Listening to Mothers III, a national survey of women ages 18-45 who gave birth in 2011-2012, the investigators conducted multivariate logistic regression to predict the likelihood of outcomes related to infant health, maternal physical and mental health, and maternal health behaviors by the use and duration of paid maternity leave. They concluded that Practice Paid maternity leave significantly predicted lower odds of maternal and infant re-hospitalization and higher odds of doing well with exercise and stress management.

Benefit requirements for substance use disorder treatment in state health insurance exchanges.
This study assessed the extent to which state insurance departments regulate the types of substance use disorder (SUD) treatment that services and medications plans must provide, and also their use of utilization controls. Data were obtained from state insurance departments via an internet-based survey, as part of the National Drug Abuse Treatment System Survey. The results indicate that states vary widely in regulations on qualified health plans’ (QHPs) administration of SUD treatment benefits; some required plans to cover all the SUD treatment services and medications assessed in this study, while others did not require plans to cover any at all. Nearly all states allowed the plans to employ utilization controls, but reported little guidance on their usage. The authors conclude that by not requiring coverage for the entire SUD continuum of care, some states hinder client access to the appropriate types of care needed for recovery.

Changes in insurance coverage among cancer patients under the Affordable Care Act.
Uninsurance among patients with newly diagnosed cancer fell by one-third in the ACA’s first year. Coverage gains were significant across numerous common cancers, multiple demographic groups, and early-stage and late-stage disease. Large gains among Hispanic individuals were consistent with findings of other ACA studies and may indicate narrowing disparities.

Understanding the relationship between Medicaid expansions and hospital closures.
The investigators hypothesized that Medicaid expansion of eligibility for childless adults prevents hospital closures because increased Medicaid coverage for previously uninsured people reduces uncompensated care expenditures and strengthens hospitals' financial position. They tested this hypothesis using data for the period 2008-16 on hospital closures and financial performance and discuss their findings in this paper.

Explaining the growth in US health care spending using state-level variation in income, insurance, and provider market dynamics.
The authors estimated a regression model for state personal health care spending for 1991-2009, then used the results to produce state-level projections of health care spending for 2010-2013 and compared those average projected state values with actual national spending for 2010-2013. They found that at least 70% of the recent slowdown in health care spending can likely be explained by long-standing patterns.

Beyond measurement and reward: methods of motivating quality improvement and accountability.
The article examines public policies designed to improve quality and accountability that do not rely on financial incentives and public reporting of provider performance. It concludes that public policies related to quality improvement should focus more on methods of enhancing professional intrinsic motivation, while recognizing the potential role of organizations to actively promote and facilitate that motivation.

Ethics review of survey research: a mandatory requirement for publication?
The authors provided guidance for journals to consider when making determinations about the necessity of ethical review for survey research projects. They stated that in situations where there is greater than minimal risk of informational or psychological harms, the survey research should have received institutional ethics oversight. They also specified that survey research projects that enroll vulnerable individuals with diminished autonomy should receive institutional ethics oversight.

Policy-oriented research on improved physician incentives for higher value health care.
Policy makers (both public and private) are seeking ways to improve the value delivered within our health care system. To inform such policy changes, this paper identifies areas in which little is known about the effects of specific incentives (FFS, salary, etc.) on the two components of value: resource use and quality. Specific suggestions are offered focusing on fundamental "building block" studies.
