Abstract
This study examines the impact of social insurance benefit restrictions on physician behaviour, using ophthalmologists as a case study. We examine whether ophthalmologists use their market power to alter their fees and rebates across services to compensate for potential policy-induced income losses. The results show that ophthalmologists substantially reduced their fees and rebates for services directly targeted by the benefit restriction compared to other medical specialists' fees and rebates. There is also some evidence that they increased their fees for services that were not targeted. High-fee charging ophthalmologists exhibited larger fee and rebate responses while the low-fee charging group raise their rebates to match the reference price provided by the policy environment.

Abstract
Health insurance premiums are primarily understood to pose financial barriers to coverage. However, the need to remit monthly premium payments may also create administrative burdens that negatively affect coverage, even in cases where affordability is a negligible concern. Using 2016-17 data from the Massachusetts health insurance Marketplace and a natural experiment, we evaluated how coverage retention was affected by the introduction of nominal (less than $10 for most enrollees) monthly premiums for plans that previously had $0 premiums. Compared with plans that maintained $0 premiums, those that took on nominal premiums saw enrollment fall by 14 percent over the following year. This attrition was attributable to terminations for nonpayment; most terminations occurred at the end of January, implying that a significant number of affected enrollees never initiated premium payments. These findings suggest that even very small premiums act as enrollment barriers, which may sometimes reflect administrative burdens more than financial hardship. Several policy approaches could mitigate adverse coverage outcomes related to nominal premiums.

Abstract
More than 16 million people receive health care coverage through the Affordable Care Act's (ACA) individual health insurance marketplaces. Many enrollees receive premium subsidies that are tied to the premium of the second least expensive silver plan available. This study investigates the consistency of the least expensive silver plan offered on Healthcare.gov from 2014 to 2021 and finds that on average, from one year to the next, the same insurer offered the least expensive silver plan in 63.1% of counties representing 54.7% of the population. However, even when the same insurer offers the least expensive plan, almost half the time, they introduce a new, less expensive plan in the next policy year. Consequently, ACA enrollees who previously purchased the least expensive silver plan may face incremental premium costs unless they spend time and effort to carefully reevaluate their choices each year. We estimate the potential premium cost of inattention and show how it varies over time and across states.

Abstract
With the passage of the American Recovery Plan Act of 2021, roughly 12 million Americans are eligible to purchase zero-premium Health Insurance Marketplace plans. Millions more are eligible for generously subsidized health plans with small, positive premiums. What difference does a premium of zero make, relative to a slightly positive premium? Using a regression discontinuity design and administrative data from Colorado, we find that zero-premium plans increase coverage, primarily by helping low-income households begin coverage sooner. The main mechanism is eliminating the transaction costs of having to make on-time payments to begin coverage. Transaction costs may be a meaningful barrier to subsidized insurance coverage take-up, particularly for low-income families.

Abstract
We use a regression discontinuity design to understand the impact of a sharp change in eligibility for Medicaid versus subsidized marketplace insurance at 138 percent of the federal poverty line on coverage, medical spending, health status, and other public program participation. We find a 5.5 percentage point shift from Medicaid to private insurance, with no net change in coverage. The shift increases individual health spending by $341 or 2 percent of income, with larger increases at higher points in the spending distribution. Two-thirds of the increase is from premiums and one-thirdfrom out-of-pocket medical spending. Self-rated health and other public program participation appear unchanged. We find no evidence of bunching below the eligibility threshold, which suggests either that individuals are willing to pay more for private insurance or that optimization frictions are high.

Abstract
OBJECTIVE To assess the prevalence of patient administrative tasks and whether they are associated with delayed and/or foregone care. DATA SOURCE March 2019 Health Reform Monitoring Survey. STUDY DESIGN We assess the prevalence of five common patient administrative tasks-scheduling, obtaining information, prior authorizations, resolving billing issues, and resolving premium problems-and associated administrative burden, defined as delayed and/or foregone care. Using multivariate logistic models, we examined the association of demographic characteristics with odds of doing tasks and experiencing burdens. Our outcome variables were five common types of administrative tasks as well as composite measures of any task, any delayed care, any foregone care, and any burden (combined delayed/foregone), respectively. DATA COLLECTION We developed and administered survey questions to a nationally representative sample of insured, nonelderly adults (n = 4155). PRINCIPAL FINDINGS The survey completion rate was 62%. Seventy-three percent of respondents reported performing at least one administrative task in the past year. About one in three task-doers, or 24.4% of respondents overall, reported delayed or foregone care due to an administrative task: Adjusted for demographics, disability status had the strongest association with administrative tasks (adjusted odds ratio [OR] 2.91, p < 0.001) and burden (adjusted OR 1.66, p < 0.001). Being a woman was associated with doing administrative tasks (adjusted OR 2.19, p < 0.001). Being a college graduate was associated with performing an administrative task (adjusted OR 2.79, p < 0.001), while higher income was associated with fewer subsequent burdens (adjusted OR 0.55, p < 0.01). CONCLUSIONS Patients frequently do administrative tasks that can create burdens resulting in delayed/foregone care. The prevalence of delayed/foregone care due to administrative tasks is comparable to similar estimates of cost-related barriers to care. Demographic disparities in burden warrant further attention. Enhancing measurement of patient administrative work and associated burdens may identify opportunities for assessing quality, value, and patient experience.

Abstract
Importance The Affordable Care Act created 2 new coverage options for uninsured adults: Medicaid expansion, which in most states provides comprehensive coverage without premiums and deductibles; and private marketplace coverage, which requires a premium contribution and cost-sharing, though with generous federal subsidies at lower incomes. How enrollment rates compare in the marketplace vs Medicaid is an important policy question as states continue to weigh alternative coverage options such as Medicaid buy-in programs, enrolling Medicaid-eligible populations into marketplace plans, or creating a public option. Objective To assess the association between income eligibility for Medicaid vs marketplace coverage and insurance enrollment among low-income adults in Colorado. Design Setting and Participants Using 2014 and 2015 all-payer claims data from Colorado and detailed income eligibility information, we used a regression discontinuity design to assess the difference in Medicaid and marketplace enrollment just below and just above 138% of the federal poverty level (FPL), the eligibility threshold between the 2 programs. The sample included nonpregnant adults aged 19 to 64 years with incomes between 75% to 400% FPL. We stratified our analysis by age, sex, chronic condition status, and urban vs rural residence. Analysis was conducted from January to October 2020. Main Outcome and Measures The main outcome was total enrollment in either Medicaid or marketplace coverage during marketplace's Open Enrollment period. Income-based health insurance eligibility was assessed as a percentage of FPL at the time of initial application for coverage. Results The primary analytical sample included 32 091 enrollees in 2014 and 55 451 in 2015, with incomes ranging from 120% to 156% FPL. Most enrollees were women (59.26% in 2014, 59.20% in 2015), resided in urban areas (70.36% in 2014, 73.08% in 2015), and had no chronic conditions (74.66% in 2014, 76.11% in 2015). For age, in 2014 and 2015, respectively, 13.22% and 13.93% were aged 19 to 25 years, 27.85% and 28.54% were aged 26 to 34 years, 23.58% and 24.34% were aged 35 to 44 years, 18.35% and 17.75% were aged 45 to 54 years, and 17.00% and 15.44% were aged 55 to 64 years. Marketplace enrollment was 81.3% (95% CI, -86.0% to -75.0%) lower than Medicaid enrollment in 2014 and 88.6% (95% CI, -90.8% to -86.0%) lower in 2015 among those close to the 138% FPL eligibility threshold. The drop-off in marketplace enrollment was largest among younger adults, aged 26 to 34 and 35 to 44 years: relative drop off -88.7% (95% CI, -93.3% to -80.8%) and -87.8% (95% CI, -90.8% to -83.9%) in 2014, and relative drop off -91.9% (95% CI, -94.5% to -87.9%) and -93.0% (95% CI, -94.5% to -91.1%) in 2015, respectively. Conclusions and Relevance In this cross-sectional study using a regression-discontinuity analysis, meaningful gaps in insurance enrollment may have existed for those with incomes just above the eligibility threshold for Medicaid expansion, especially among younger adults. Policies expanding Medicaid income eligibility or zero-dollar premium marketplace plans are likely to be more effective at inducing enrollment than subsidized private plans with premium requirements.

Abstract
The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides breastfeeding support and free formula to low-income participating infants in the U.S. Literature has consistently documented worse breastfeeding outcomes in WIC infants and children than in non-participants, although self-selection bias poses a challenge in examining the relationship between WIC participation and breastfeeding in low-income mother-child dyads. The WIC program adopted a comprehensive food package revision in 2009, the first one in four decades. Since that time, few national studies have examined the relationship between WIC participation and breastfeeding while controlling for the endogeneity of WIC participation with the propensity score method. This paper applied an instrumental variable (IV) approach on a large, nationally representative survey sample of children, the National Immunization Surveys (NIS), to examine the relationship between WIC participation and breastfeeding among children born between 2005 and 2014. We identified state Supplemental Nutrition Assistance Program (SNAP) enrollment rates and SNAP Policy Indices as valid IVs to address WIC participation endogeneity. Without the IVs, WIC participation had a significantly negative relationship with breastfeeding. After addressing endogeneity using the IVs, the relationship became insignificant in the whole sample and in the subpopulations across race/ethnicity and child gender. The neutrality of WIC participation on breastfeeding is important for policy makers to understand in seeking to improve breastfeeding among WIC participants.

Abstract
OBJECTIVES To investigate whether negative media coverage of the human papillomavirus (HPV) vaccine led to a decrease in the uptake of the first dose of the HPV vaccine (HPV1) in Denmark and, importantly, whether some groups of individuals were more susceptible to negative media coverage. METHODS We measured HPV vaccine uptake of 12-year-old girls born in 2001 to 2004 using Danish administrative data. A quasi-experimental design was employed to assess whether a documentary that was critical of the HPV vaccine and aired in March 2015 affected HPV uptake. RESULTS The documentary led to a quick and substantial decrease in the monthly propensity to vaccinate, which dropped 3 percentage points-or about 50%-in response to the documentary. Responses differed substantially across subgroups, and girls from families with high socioeconomic status (SES) were more susceptible to the negative media coverage. CONCLUSIONS Susceptibility to negative media coverage varied substantially across subgroups, highlighting the need for policy makers to appropriately target and differentiate initiatives to improve vaccine compliance rates.

Abstract
We develop a set of frameworks for welfare analysis of Medicaid and apply them to the Oregon Health Insurance Experiment, a Medicaid expansion for low-income, uninsured adults that occurred via random assignment. Across different approaches, we estimate recipient willingness to pay for Medicaid between $0.5 and $1.2 per dollar of the resource cost of providing Medicaid; estimates of the expected transfer Medicaid provides to recipients are relatively stable across approaches, but estimates of its additional value from risk protection are more variable. We also estimate that the resource cost of providing Medicaid to an additional recipient is only 40% of Medicaid's total cost; 60% of Medicaid spending is a transfer to providers of uncompensated care for the low-income uninsured.

Abstract
In 2015, Indiana expanded eligibility for Medicaid under the Affordable Care Act (ACA) through a unique waiver, Healthy Indiana Plan 2.0, which requires enrollees to make monthly contributions to an account that is similar to a health savings account to receive full benefits. Enrollees who fail to make these contributions receive less generous benefits if their income is below the federal poverty level, and if it is 100-138 percent of poverty, they are locked out of coverage for six months. We estimated the impact of this expansion on coverage rates and compared the effects to results from other states that expanded Medicaid after 2014. We found that Indiana's coverage gains (relative to pre-ACA uninsurance rates) were smaller than gains in neighboring expansion states, but larger than those in other states. These results imply that while one potential reason for Indiana's lower gains relative to neighboring states was its cost-sharing requirements, expansion led to unquestionable coverage gains in the state.

Abstract
OBJECTIVE To isolate the effect of greater inpatient cost-sharing on Medicaid entry among Medicare beneficiaries. DATA SOURCES Medicare administrative data (years 2007-2010) were linked to nursing home assessments and area-level socioeconomic indicators. STUDY DESIGN Medicare beneficiaries who are readmitted to a hospital must pay an additional deductible ($1,100 in 2010) if their readmission occurs more than 59 days following discharge. In a regression discontinuity analysis, we take advantage of this Medicare benefit feature to test whether beneficiaries with greater cost-sharing have higher rates of Medicaid enrollment. DATA EXTRACTION METHODS We identified 221,248 Medicare beneficiaries with an initial hospital stay and a readmission 53-59 days later (no deductible) or 60-66 days later (charged a deductible). PRINCIPAL FINDINGS Among beneficiaries in low-socioeconomic areas with two hospitalizations, those readmitted 60-66 days after discharge were 21 percent more likely to join Medicaid compared with those readmitted 53-59 days following their initial hospitalization (absolute difference in adjusted risk of Medicaid entry: 3.7 percent vs. 3.1 percent, p = .01). CONCLUSIONS Increasing Medicare cost-sharing requirements may promote Medicaid enrollment among low-income beneficiaries. Potential savings from an increased cost-sharing in the Medicare program may be offset by increased Medicaid participation.

Abstract
In states that expanded Medicaid eligibility under the Affordable Care Act, nonelderly near-poor adults-those with family incomes of 100-138 percent of the federal poverty level-are generally eligible for Medicaid, with no premiums and minimal cost sharing. In states that did not expand eligibility, these adults may qualify for premium tax credits to purchase Marketplace plans that have out-of-pocket premiums and cost-sharing requirements. We used data for 2010-15 to estimate the effects of Medicaid expansion on coverage and out-of-pocket expenses, compared to the effects of Marketplace coverage. For adults with family incomes of 100-138 percent of poverty, living in a Medicaid expansion state was associated with a 4.5-percentage-point reduction in the probability of being uninsured, a $344 decline in average total out-of-pocket spending, a 4.1-percentage-point decline in high out-of-pocket spending burden (that is, spending more than 10 percent of income), and a 7.7-percentage-point decline in the probability of having any out-of-pocket spending relative to living in a nonexpansion state. These findings suggest that policies that substitute Marketplace for Medicaid eligibility could lower coverage rates and increase out-of-pocket expenses for enrollees.

Abstract
This paper assesses the impact of eligibility for a free means-tested complementary health insurance plan, called Couverture Maladie Universelle Complémentaire (CMUC), on doctor visits. We use information on the selection rule to qualify for the plan to identify the effect of eligibility and adopt a regression discontinuity approach. Our sample consists of low-income individuals enrolled in the Health Insurance Fund and recipients of social benefits from the Family Allowance Fund of an urban area in Northern France. Our findings do not show significant impacts of the CMUC threshold on the number of doctor visits within the full sample. Among the subsample of adults under 30 years old, however, eligible individuals are more likely to see a specialist and have, on average, significantly more specialist visits than non-eligible individuals. This specific impact of the CMUC cut-off point among young adults may be explained by the fact that young adults are less likely to be covered by a complementary health insurance plan when they are not recipients of the CMUC plan. © 2017 The Authors.

Helleringer S, Asuming PO, Abdelwahab J. The effect of mass vaccination campaigns against polio on the utilization of routine immunization services: A regression discontinuity design. Vaccine 2016; 34:3817-22. [PMID: 27269060 DOI: 10.1016/j.vaccine.2016.05.037] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2016] [Revised: 05/13/2016] [Accepted: 05/25/2016] [Indexed: 12/16/2022]
Abstract
BACKGROUND In most low and middle-income countries (LMIC), vaccines are primarily distributed by routine immunization services (RI) at health facilities. Additional opportunities for vaccination are also provided through mass vaccination campaigns, conducted periodically as part of disease-specific initiatives. It is unclear whether these campaigns are detrimental to RI services, or wether they may stimulate the utilization of RI. METHODS Unobserved confounders and reverse causality have limited existing evaluations of the effects of mass vaccination campaigns on RI services. We explored the use of a regression discontinuity design (RDD) to measure these effects more precisely. This is a quasi-experimental method, which exploits random variations in birth dates to identify the causal effects of vaccination campaigns. We applied RDD to survey data on a nationwide vaccination campaign against Polio conducted in Bangladesh. RESULTS We compared systematically the children born immediately before vs. after the vaccination campaign. These two groups had similar background characteristics, but differed by their exposure to the vaccination campaign. Contrary to previous studies, exposure to the campaign had positive effects on RI utilization. Children exposed to the campaign received between 0.296 and 0.469 additional doses of DPT vaccine by age 4months than unexposed children. CONCLUSIONS RDD constitutes a promising tool to assess the effects of mass vaccination campaigns on RI services. It could be tested in additional settings, using larger and more precise datasets. It could also be extended to measure the effects of other disease-specific interventions on the functioning of health systems, in particular those that occur at a discrete point in time and/or include age-related eligibility criteria.

Sabik LM, Gandhi SO. Copayments and Emergency Department Use Among Adult Medicaid Enrollees. HEALTH ECONOMICS 2016; 25:529-542.

Abstract
A number of state Medicaid programs have recently proposed or implemented new or increased copayments for nonemergent emergency department (ED) visits. Evidence suggests that copayments generally reduce the level of healthcare utilization, although there is little specific evidence regarding the effectiveness of copayments in reducing nonurgent ED use among Medicaid enrollees or other low-income populations. Encouraging efficient and appropriate use of healthcare services will be of particular importance for Medicaid programs as they expand under the Patient Protection and Affordable Care Act. This analysis uses national data from 2001 to 2009 to examine the effect of copayments on nonurgent ED utilization among nonelderly adult enrollees. We find that visits among Medicaid enrollees in state-years where a copayment is in place are significantly less likely to be for nonurgent reasons. Our findings suggest that copayments may be an effective tool for reducing use of the ED for nonurgent care.

Health Insurance Effects on Preventive Care and Health: A Methodologic Review. Am J Prev Med 2016; 50:S27-S33. [PMID: 27102855 DOI: 10.1016/j.amepre.2016.01.003] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2015] [Revised: 12/21/2015] [Accepted: 01/12/2016] [Indexed: 11/24/2022]
Abstract
The Affordable Care Act has led to significant gains in insurance coverage and reduced the cost of preventive care for millions of Americans. There is considerable interest in understanding how these changes will impact the use of preventive care services and health outcomes. Obtaining unbiased estimates of the impact of insurance on these outcomes is challenging because of inherent differences between insured and uninsured individuals. This article reviews common experimental and quasi-experimental approaches researchers have used in the past to address this problem, including RCTs, differences-in-differences analyses, and regression discontinuity. In each case, the key assumptions underlying the models are discussed alongside some of the main research findings related to prevention and health. The review concludes with a discussion of how experimental and quasi-experimental methods can be used to study the impact of the Affordable Care Act on preventive care and health outcomes.

Abstract
BACKGROUND Premiums are required in Medicaid and the Children's Health Insurance Program in many states. Effects of premiums are raised in policy debates. OBJECTIVE Our objective was to review effects of premiums on children's coverage and access. DATA SOURCES PubMed was used to search academic literature from 1995 to 2014. STUDY SELECTION Two reviewers initially screened studies by using abstracts and titles, and 1 additional reviewer screened proposed studies. Included studies focused on publicly insured children, evaluated premium changes in at least 1 state/local program, and used longitudinal or repeated cross-sectional data with pre/postchange measures. DATA EXTRACTION We identified 263 studies of which 17 met inclusion criteria. RESULTS Four studies examined population-level coverage effects by using national survey data, 11 studies examined trends in disenrollment and reenrollment by using administrative data, and 2 studies measured additional outcomes. No eligible studies evaluated health status effects. Increases in premiums were associated with increased disenrollment rates in 7 studies that permitted comparison. Larger premium increases and stringent enforcement tended to have larger effects on disenrollment. At a population level, premiums reduce public insurance enrollment and may increase the uninsured rate for lower-income children. Little is known about effects of premiums on spending or access to care, but 1 study reveals premiums are unlikely to yield substantial revenue. LIMITATIONS Effect sizes were difficult to compare across studies with administrative data. CONCLUSIONS Public insurance premiums often increase disenrollment from public insurance and may have unintended consequences on overall coverage for low-income children.

Abstract
Despite passage of the Affordable Care Act in 2010, the U.S. health care crisis continues. While coverage has been expanded, the reform will leave 27 million people uninsured in 2024, according to the Congressional Budget Office. Much of the new coverage is of low actuarial value with high cost-sharing requirements, creating barriers to access. Choice of physician is restricted to narrow networks of providers. Recent measures of uninsurance, underinsurance, access to care, and health care costs are given. Changes in Medicare, particularly privatization and the rise of specialty drug tiers that limit access to medically necessary medications, are reviewed. Data on a new wave of consolidation among hospitals, medical groups, insurers, and drug companies are presented. The rise of ultra-high-price drugs, such as Solvadi, is raising pharmaceutical costs, particularly in Medicaid, the program for low-income Americans. International health comparisons continue to show the United States performing poorly in relation to other countries. Recent polling data are presented, showing support for more fundamental reform.

Abstract
Medicaid is fundamental to near universal health insurance coverage under the 2010 Affordable Care Act (ACA). Its goal of broadening the program to all households with income at or below 138 percent of the federal poverty level was thwarted in 2012 by a Supreme Court decision that allowed the states to choose whether or not they would join. This essay seeks to assess the status of Pennsylvania with regard to the Medicaid expansion controversy. It briefly describes the Keystone State's existing Medicaid program and the potential impact of the ACA on its growth. It then discusses Governor Tom Corbett's market-based alternative and what he achieved in his deliberations with the Obama administration. The article also discusses some of the financial considerations facing Pennsylvania policy makers in the expansion decision, the role of three of the more influential lobby groups, and the problematic situation of the medically uninsured population.

Abstract
It might seem strange to ask whether increasing access to medical care can improve children's health. Yet Lindsey Leininger and Helen Levy begin by pointing out that access to care plays a smaller role than we might think, and that many other factors, such as those discussed elsewhere in this issue, strongly influence children's health. Nonetheless, they find that, on the whole, policies to improve access indeed improve children's health, with the caveat that context plays a big role-medical care "matters more at some times, or for some children, than others." Focusing on studies that can plausibly show a causal effect between policies to increase access and better health for children, and starting from an economic framework, they consider both the demand for and the supply of health care. On the demand side, they examine what happens when the government expands public insurance programs (such as Medicaid), or when parents are offered financial incentives to take their children to preventive appointments. On the supply side, they look at what happens when public insurance programs increase the payments that they offer to health-care providers, or when health-care providers are placed directly in schools where children spend their days. They also examine how the Affordable Care Act is likely to affect children's access to medical care. Leininger and Levy reach three main conclusions. First, despite tremendous progress in recent decades, not all children have insurance coverage, and immigrant children are especially vulnerable. Second, insurance coverage alone doesn't guarantee access to care, and insured children may still face barriers to getting the care they need. Finally, as this issue of Future of Children demonstrates, access to care is only one of the factors that policy makers should consider as they seek to make the nation's children healthier.
