Measurement matters: changing penalty calculations under the Hospital Acquired Condition Reduction Program (HACRP) cost hospitals millions.
Since October 2014, the Centers for Medicare and Medicaid Services has penalized 25% of U.S. hospitals with the highest rates of hospital-acquired conditions under the Hospital Acquired Conditions Reduction Program (HACRP). While early evaluations of the HACRP program reported cumulative reductions in hospital-acquired conditions, more recent studies have not found a clear association between receipt of the HACRP penalty and hospital quality of care. In this article, the authors posit that some of this disconnect may be driven by frequent scoring updates.

Medicare Accountable Care Organizations and the adoption of new surgical technology.
Dissemination of new surgical technology is a major contributor to healthcare spending growth. Accountable care organization (ACO) policy aims to control spending while maintaining quality. As a result, ACOs provide incentive for hospitals to selectively adopt newer procedures with high value. In this retrospective cohort study the investigators concluded that despite ACO policy incentives to selectively adopt newer surgical technology, ACO participation was not associated with differences in rate of surgery or use of newer surgical technology for 6 major surgical procedures.

Prevalence of pre-existing conditions among community health center patients with COVID-19: implications for the Patient Protection and Affordable Care Act.
Researchers described the prevalence of pre-existing conditions among community health center patients overall and those with COVID-19 by race/ethnicity. Electronic health record data from OCHIN, a network of 396 community health centers across 14 states, was used. They concluded that since the future of the Patient Protection and Affordable Care Act is uncertain, and since the long-term health effects of COVID-19 are largely unknown, ensuring that people with pre-existing conditions can acquire health insurance is essential to achieving health equity.

Travel time to radiation oncology facilities in the United States and the influence of Certificate of Need Policies.
The authors’ goal was to evaluate travel times to US radiation oncology (RO) facilities and to assess the association with Certificate of Need (CON) policies. RO facilities were identified from the 2018 National Plan and Provider Enumeration System. They found that isolated rural US census tracts, accounting for 9.4 million Americans, have nearly 1-hour longer adjusted travel time to the nearest RO facility, compared with urban tracts. CON laws had region-dependent associations with prolonged travel.

Assessment of the Patient Protection and Affordable Care Act's increase in fees for primary care and access to care for dual-eligible beneficiaries.
The purpose of this study was to examine the association between the Affordable Care Act (ACA) fee bump and primary care visits for dual-eligible Medicare and Medicaid beneficiaries. Medicare claims data from 2012 to 2016 was used. Findings showed that the ACA fee bump was not associated with increases in primary care visits for dual-eligible Medicare and Medicaid beneficiaries. Additionally, visits for dual-eligible beneficiaries with primary care physicians decreased after the ACA, a decrease that was partially offset by increases in visits with nonphysician clinicians.

Impacts of the Affordable Care Act on receipt of women's preventive services in Community Health Centers in Medicaid expansion and nonexpansion states.
Researchers assessed whether ACA implementation and Medicaid expansion were followed by greater receipt of recommended preventive services among women and girls in a large network of community health centers. Data was collected from electronic health records in 14 states. The researchers found that among female patients at community health centers, receipt of recommended preventive care improved after ACA implementation in both Medicaid expansion and non-expansion states, although the overall rates remained low. They recommended continued support to overcome barriers to preventive care in this population.

Integrating fundamental cause theory and Bourdieu to explain pathways between socioeconomic status and health: the case of health insurance denials for genetic testing.
This paper proposes that Pierre Bourdieu's theories of capital and symbolic power can be integrated with fundamental cause theory to address limitations in the latter theory, making it more useful in health disparities research. This work deepens appreciation for the durable relationship between socioeconomic status and health. Study results reveal the multiple and complex mechanisms that play a role in access to healthcare services, which has significant implications for how we think about the role of health policy in addressing health disparities.

Medical marijuana laws, marijuana use, and opioid-related outcomes among women in the United States.
This study examined whether state medical marijuana laws (MMLs) was associated with lower levels of opioid-related outcomes. Data was drawn from the 2002-2014 National Survey on Drug Use and Health to compare opioid misuse in states with and without MMLs among all women, pregnant women, and parenting women. It also invested the impact of MMLs on marijuana use and marijuana use disorder. There was found to be no association of MMLs with opioid misuse, opioid misuse initiation, or opioid use disorder among all women, pregnant women and parenting women. However there was a positive correlation with marijuana use and marijuana use disorder among all women and women with children. MMLs were also associated with an increase in the frequency of opioid misuse in pregnant women and a decrease in the frequency of opioid misuse for parenting women.

The impact of funding for federally qualified health centers on utilization and emergency department visits in Massachusetts.
This retrospective study examined the impact of funding for federally qualified health centers (FQHCs) on utilization and emergency department (ED) visits in Massachusetts. The authors theorized that greater funding for FQHCs could increase the local availability of clinic-based care and reduce more costly resource use, such as ED visits. Data from the Massachusetts All Payer Claims Database (APCD) 2010-2013 was used that included enrollees in 559 Massachusetts ZIP codes (2010 numbers 6,173,563). They calculated shift-share predictions of changes in FQHC funding at the ZIP code-level for FQHCs that received Community Health Center funds in any year. They found that a standard deviation increase in prior year FQHC funding (31%) was associated with a 2.3% increase in enrollees with FQHC visits and a 1.3% decrease in enrollees at EDs. However, there were no significant changes in emergent ED visit rates.

Carve-out plan financial requirements associated with national behavioral health parity.
The authors examined changes in carve-out financial requirements following the Mental Health Parity and Addiction Equity Act (MHPAEA). They found that the MHPAEA was associated with increased generosity in most observed financial requirements, but increased use of deductibles may have reduced generosity for some patients.

Hospitals strengthened relationships with close partners after joining accountable care organizations.
This study tested the hypothesis that hospitals participating in Medicare Accountable Care Organizations (ACOs) try to influence where their patients receive care in order to achieve quality and cost containment goals. The authors studied hospitals participating in ACO from 2010 to 2014. ACO hospitals shared patients 4.4% more than non-ACO hospitals. This occurred disproportionately at hospitals that already shared a high proportion of their patients prior to participation and among hospitals in ACOs characterized as physician-hospital collaborations.

Private/marketplace insurance in community health centers 5 years post-affordable care act in Medicaid expansion and non-expansion states.
This study compared differences in private/marketplace insurance in community health centers (CHCs) 5 years post-Affordable Care Act (ACA) in Medicaid expansion and non-expansion states. Electronic health record data from 702,663 patients in clinics across 20 states was used to explore trends in private/market insurance post-expansion and whether CHC patients retain private/marketplace insurance. The authors found that patients in non-expansion state CHCs relied more heavily on private/marketplace insurance than patients in expansive states and had increased visits from 2014 through 2018. There was a more pronounced seasonal variation in private/marketplace-insured visits too. A greater percentage of those who in non-expansion states did not retain private/marketplace insurance become uninsured, while those in expansion states gained other types of health insurance.

Public support for social safety-net policies for COVID-19 in the United States, April 2020.
Researchers examined public support for health insurance, income support, and unemployment policies during the initial phase of disease transmission and economic distress following the COVID-19 outbreak and assessed varying public support based on beliefs about the role of government. They fielded a nationally representative survey of US adults from April 7-13, 2020. Their results indicate that, during the initial phase of the COVID-19 pandemic in early April 2020, most US adults favored a range of safety-net policies to ameliorate its negative health and economic consequences, with public support being the highest among those favoring a stronger governmental role in society.

The role of marketplace policy on welcome mat effects for children eligible for Medicaid or the Children's Health Insurance Program.
This study examined the role of marketplace policy on “welcome mat” effects for children eligible for Medicaid or the Children’s Health Insurance Program (CHIP). Data from the American Community Survey from 2013-2018 was used to estimate the relationship between Marketplace policy and increases in Medicaid/CHIP coverage among pre-ACA eligible children after the implementation of the Affordable Care Act (ACA). The sample included non-disabled citizen children ages 0-18 at 139-250% federal poverty level who were Medicaid/CHIP-eligible before and after implementation of the ACA. Marketplace policies and enrollment were compared in expansion states versus non-expansion states. Public coverage did increase more in states that empowered their Marketplace to enroll publicly-eligible applicants directly into Medicaid/CHIP. This was driven by enrollment policy, not by choice of state-based versus federal-based Marketplaces. Welcome mats were largest in expansion states and increases ranged from 9 to 13 percentage points in enrollment.

Evaluation of US hospital episode spending for acute inpatient conditions after the Patient Protection and Affordable Care Act.
This study evaluated the association between enactment of Affordable Care Act (ACA) reforms and 30-day price standardized hospital episode spending for Medicare patients. Reforms to reduce spending were targeted to acute care hospitals and often focused on specific diagnoses such as acute myocardial infarction, heart failure, and pneumonia. The policy evaluation included index discharges between January 2008 and August 31, 2015 from a random 20% sample of Medicare beneficiaries. Three different estimation approaches were used to evaluate the association between reforms and episode spending: difference-in-difference (DID) analysis among acute care hospitals; a DID analysis comparing acute care hospitals and critical care hospitals; and a generalized synthetic control analysis, comparing acute care and critical access hospitals. A total of 7,634,242 index discharges were included. All 3 approaches found that ACA-associated spending reforms were associated with a significant reduction in episode spending.

Trends in birth rates after elimination of cost sharing for contraception by the Patient Protection and Affordable Care Act.
Researchers evaluated changes in birth rates by income level among commercially insured women before (2008-2013) and after (2014-2018) the elimination of cost sharing for contraception under the Patient Protection and Affordable Care Act (ACA). The analytic sample included over 4.5 million women enrolled in 47,721 health plans. In this cross-sectional study, the researchers found that the elimination of cost sharing for contraception under the ACA was associated with improvements in contraceptive method prescription fills and a decrease in births among commercially insured women. Women with low income had more precipitous decreases than women with higher income, suggesting that enhanced access to contraception may address well-documented income-related disparities in unintended birth rates.

Changes in health care-related financial burden for US families with children associated with the Affordable Care Act.
The Affordable Care Act (ACA) sought to improve access and affordability of health insurance. Although most ACA policies targeted childless adults, the extent to which these policies also impacted families with children remains unclear. The purpose of this study was to examine changes in health care-related financial burden for US families with children before and after the ACA was implemented based on income eligibility for ACA policies.

Evaluation of alcohol taxes as a public health opportunity to reduce liver transplant listings for alcohol-related liver disease.
Alcohol-related liver disease (ALD) is a leading indication for liver transplantation. In this study, the investigators evaluated alcohol taxes as a public health opportunity to reduce liver transplant listings for alcohol-related liver disease. The investigators concluded that transplant listings for ALD were directly associated with spirit consumption and inversely associated with spirits excise taxes. They indicate that these findings suggest a possible public health benefit of increasing excise taxes for spirits.

Association between Medicaid expansion, dental coverage policies for adults, and children's receipt of preventive dental services.
Researchers examined whether low-income children's use of preventive dental services is linked to variation in state Medicaid policies that affect parents' access to dental care in Medicaid. Using MEPS data along with Area Health Resources File and Medicaid adult dental coverage policies, they found no change in children's receipt of preventive dental care associated with Medicaid expansions in states that covered vs did not cover preventive dental services for adults. They concluded that factors other than parental access to dental benefits through Medicaid may be more salient determinants of preventive dental care use among low-income children.

Association of state-level opioid-reduction policies with pediatric opioid poisoning.
Opioid-reduction policies have been enacted by US states to address the opioid epidemic. Evidence of an association between policy implementation and decreased rates of pediatric opioid poisoning provides further justification for expanded implementation of these policies. The purpose of this study was to examine the association of 3 state-level opioid-reduction policies with the rate of opioid poisoning in children and adolescents.

New evidence of state variation in Medicaid payment policies for dual Medicare-Medicaid enrollees.
The authors developed the first longitudinal database of state Medicaid policies for paying the cost sharing in Medicare Part B for services provided to dual Medicare-Medicaid enrollees (duals), and an index summarizing the impact of these policies on payments for physician office services. Information from 2004-2018 was consolidated from online Medicaid policy documents, state laws, and policy data reported to them by state Medicaid programs. The database showed that in 2018 42 states had policies to limit Medicaid payments of Medicare cost sharing when Medicaid’s fee schedule was lower than Medicare’s. This was an increase from 36 such states in 2004. In most states, combined Medicare and Medicare payments for evaluation and management services provided to duals averaged 78% of the Medicare allowed amount for these services.

Staffing trends in magnet and non-magnet hospitals after state legislation.
This study examined whether there was a difference in staffing of registered nurses in Magnet and non-Magnet hospitals using unit-level, publicly available data in New Jersey. This secondary analysis of longitudinal RN staffing data was conducted using 64 hospitals representing 12 nursing specialties during the time span of 2008 to 2015. There was a slight increase in staffing at Magnet hospitals compared to non-Magnet hospitals, but RN staffing improved in all hospitals. No meaningful difference in staffing for all 12 specialties was found.

The impact of paid family leave in the United States on birth outcomes and mortality in the first year of life.
The purpose of this study was to evaluate the effect of paid family leave in California on statewide rates of preterm birth, low birthweight, post-neonatal mortality, and overall infant mortality. Probabilistic methods were used to match records of live birth with maternal and newborn hospital records; only singleton births were included in the study. Rates of infant health outcomes before and after implementation of the 2004 policy in California were compared with rates in two states that had no paid family leave policy. Findings showed that implementation of paid family leave policies in California was associated with a 12-percent reduction in post-neonatal mortality after adjusting for maternal and neonatal factors.

Association between statewide school closure and COVID-19 incidence and mortality in the US.
This study examined whether school closures between March and May due to the beginning of the COVID-19 pandemic was associated with decreased COVID-19 incidence and mortality. States were examined in quartiles using the number of cases per 100,000 population. States with the lowest cumulative incidence had the most significant decline (-72%) in cases compared to states with the highest incidence (-49%). States that closed schools earlier had the largest reduction in incidence and mortality.
