Shift in U.S. payer responsibility for the acute care of violent injuries after the Affordable Care Act: Implications for prevention.
In this study, the investigators determined the total annual charges for the acute care of injuries from interpersonal violence and the shift in financial responsibility for these charges after the Medicaid expansion from the Affordable Care Act in 2014. After Medicaid expansion, taxpayers are now accountable for nearly half of the $10.7 billion in annual charges for the acute care of violent injury in the U.S. The investigators suggest that these findings highlight the benefit to state Medicaid programs of preventing interpersonal violence.

Effect of site-neutral payment policy on long-term acute care hospital use.
The purpose of this study was to assess the projected effect of the Centers for Medicare and Medicaid Services new site-neutral payment policy, which aims to decrease unnecessary long-term acute care hospital (LTACH) admissions by reducing reimbursements for less-ill individuals by 2020. The investigators concluded that the site-neutral payment policy may limit LTACH access in existing LTAC-scarce markets, with potential adverse implications for recovery of hospitalized older adults.

Paying more for less? Insurer competition and health plan generosity in the Medicare Advantage program.
This paper explored the relationship between insurer competition and health plan benefit generosity by examining the impact of a regulatory change that caused the cancellation of 40% of the private plans in Medicare. The investigator found that insurers in markets affected by cancellation reduced the benefit generosity of the plans remaining in the market.

Does limiting allowable rating variation in the small group health insurance market affect employer self-insurance?
This study evaluated the impact of limiting allowable rating variation on employer self-insurance across industries with varied health risk. The investigators found that lower-risk employers subject to laws limiting allowable premium rating variation had a predicted probability of self-insurance that was about 18 percentage points higher than otherwise-similar higher-risk employers, suggesting that selection concerns are warranted.

No association found between the Medicaid primary care fee bump and physician-reported participation in Medicaid.
The Affordable Care Act required states in 2013 and 2014 to raise Medicaid payment rates to primary care physicians for certain services to the level of Medicare rates. The result was an average 73 percent increase in primary care Medicaid payments for qualifying physicians. This study used nationally representative data to examine the association between this Medicaid "fee bump" and physician-reported measures of participation in Medicaid. No such association was found. The lack of a sizable change in measures of physician participation in Medicaid may have been due to the temporary nature of the fee bump.

Intrauterine device insertion before and after mandated health care coverage: the importance of baseline costs.
This study evaluated changes in out-of-pocket cost for intrauterine device (IUD) placement before and after mandated coverage of contraceptive services and examined how changes in out-of-pocket cost influenced IUD insertion as a function of baseline cost. It concluded that women in plans with the greatest reduction in out-of-pocket cost after mandated coverage of contraception had the greatest gains in IUD insertion.

Oregon Medicaid Expenditures after the 2014 Affordable Care Act Medicaid expansion: over-time differences among new, returning, and continuously insured enrollees.
This study assessed health care expenditures among Medicaid enrollees in the 24 months after Oregon's 2014 Medicaid expansions and examine whether expenditure patterns were different among the newly, returning, and continuously insured (CI). After initial increases, newly and returning insured (RI) outpatient expenditures dropped below CI. Expenditures for emergency department and dental services among the RI remained higher than among the newly insured.

Medicare Advantage penetration and hospital costs before and after the Affordable Care Act.
This study investigated the relationship between Medicare Advantage (MA) program growth and inpatient hospital costs and utilization before and after the ACA. Its results suggest that MA enrollment growth is associated with diminished spillover reductions in hospital admission costs after the ACA. Researchers did not observe a strong relationship between MA enrollment and inpatient days per enrollee

Can accountable care organisations really improve the English NHS? Lessons from the United States.
The authors summarize evidence on accountable care organizations in the US - including what they look like, their effect on the quality and cost of healthcare, and how they are redesigning care. Recognizing major differences in context, they offer lessons from the US experience for National Health Service policy makers as they consider the future of similar ventures in England.

The hidden roles that management partners play in accountable care organizations.
This study sought to understand the prevalence of nonprovider management partners' involvement in accountable care organizations (ACOs), the services these partners provide, and the structure of ACOs that have such partners. It found that 37 percent of ACOs reported having a management partner, and two-thirds of these ACOs reported that the partner shared in the financial risks or rewards..

Refinement of the Affordable Care Act.
This article begins by listing some of the major reasons critics dislike the Affordable Care Act (ACA), then discusses the validity of these concerns from an economics perspective. Suggestions for refining the ACA and its market-based insurance system are then offered, with the goals of lowering insurance premiums, improving coverage rates, and/or addressing the concerns of ACA critics.

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.
