The Effects of the Patient Protection and Affordable Care Act on Children’s Health Coverage

Associations Between Medicaid Expansion and Timely Repair of Cleft Lip and Palate

The expansion of Medicaid under the Affordable Care Act (ACA) increased access to health care for many low-income children. However, the impact of this expansion on the timing of primary cleft lip and palate repair remains unclear. This study aimed to evaluate whether Medicaid expansion improved access to timely cleft lip and palate repair and whether it reduced preexisting ethnoracial disparities. Using a quasi-experimental design, the study analyzed data from 44 pediatric surgical centers across the United States. The results showed that Medicaid expansion was associated with a 9.0 percentage-point increase in delayed cleft lip repairs, resulting in an average delay of 16 days. Non-White patients were disproportionately affected by this delay, experiencing a 14.8 percentage-point increase compared with a 4.9 percentage-point increase for White patients. In contrast, Medicaid expansion had no significant effect on the timing of palate repair or on ethnoracial disparities in palate repair. The study underscores the importance of monitoring unintended consequences of large-scale health system changes, especially those affecting disadvantaged populations. Delayed cleft lip repair can lead to worse outcomes for patients, and the disproportionate impact on non-White patients is concerning. Further research is needed to identify the reasons for this delay and to mitigate its effects. Overall, the study highlights the need for ongoing vigilance to ensure that health care policies and interventions do not inadvertently worsen health disparities.

Impacts of Publicly Funded Health Insurance for Adults on Children's Academic Achievement. SOUTHERN ECONOMIC JOURNAL 2023;89:860-884. [PMID: 38845841 PMCID: PMC11156232 DOI: 10.1002/soej.12614]

Empirical evidence demonstrates that publicly funded adult health insurance through the Affordable Care Act (ACA) has had positive effects on low-income adults. We examine whether the ACA's Medicaid expansions influenced child development and family functioning in low-income households. We use a difference-in-differences framework exploiting cross-state policy variation and focusing on children in low-income families from a nationally representative, longitudinal sample followed from kindergarten to fifth grade. The ACA Medicaid expansions improved children's reading test scores by approximately 2 percent (0.04 SD). Potential mechanisms for these effects within families are more time spent reading at home, less parental help with homework, and eating dinner together. We find no effects on children's math test scores or socioemotional skills.

Mapping 2 Decades of Research in Health Services Research, Health Policy, and Health Economics Journals

OBJECTIVE

To identify major research topics and exhibit trends in these topics in 15 health services research, health policy, and health economics journals over 2 decades.

DATA SOURCES

The study sample of 35,159 abstracts (1999-2020) were collected from PubMed for 15 journals.

STUDY DESIGN

The study used a 3-phase approach for text analyses: (1) developing the corpus of 40,618 references from PubMed (excluding 5459 of those without abstract or author information); (2) preprocessing and generating the term list using natural language processing to eliminate irrelevant textual data and identify important terms and phrases; (3) analyzing the preprocessed text data using latent semantic analysis, topic analyses, and multiple correspondence analysis.

PRINCIPAL FINDINGS

Application of analyses generated 16 major research topics: (1) implementation/intervention science; (2) HIV and women's health; (3) outcomes research and quality; (4) veterans/military studies; (5) provider/primary-care interventions; (6) geriatrics and formal/informal care; (7) policies and health outcomes; (8) medication treatment/therapy; (9) patient interventions; (10) health insurance legislation and policies; (11) public health policies; (12) literature reviews; (13) cost-effectiveness and economic evaluation; (14) cancer care; (15) workforce issues; and (16) socioeconomic status and disparities. The 2-dimensional map revealed that some journals have stronger associations with specific topics. Findings were not consistent with previous studies based on user perceptions.

CONCLUSION

Findings of this study can be used by the stakeholders of health services research, policy, and economics to develop future research agendas, target journal submissions, and generate interdisciplinary solutions by examining overlapping journals for particular topics.

The Effects of ACA Medicaid Expansions on Health After 5 Years

We examine the Affordable Care Act Medicaid expansion effects on self-rated health status over 5 years. The study uses data from the Behavioral Risk Factor Surveillance System for 2011-2018 and a difference-in-differences design. There is improvement in health status on a 1 to 5 point scale from poor to excellent health among individuals below 100% of the federal poverty line by 0.031, 0.068, 0.031, 0.064, and 0.087 points in 2014, 2015, 2016, 2017, and 2018, respectively. Changes in 2015, 2017, and 2018 are statistically significant (p < .05), and the 2014 change is marginally significant. The difference between 2014 and 2018 effects is statistically significant (p < .05). In most years, we cannot distinguish changes in days not in good physical or mental health from no effect. Overall, there is only minimal evidence for effects intensifying over time, suggesting that health gains thus far have mostly occurred early on due to unmet needs among those previously uninsured.

The Impact Of Household Health Insurance Coverage Gains On Children's Achievement In Iowa: Evidence From The ACA

Low family income is associated with worse child academic achievement. Little is known about how health insurance expansions affect children's achievement in low-income households. This study examined the effects of the Affordable Care Act's coverage expansions primarily for Medicaid and Marketplace enrollment, beginning in 2014, on children's academic achievement in Iowa. The study employed a unique linkage of birth certificates and data on standardized school tests for children in Iowa and took advantage of differences in uninsurance rates across areas in the state before the ACA insurance expansions. There is evidence that the ACA expansions beginning in 2014 were associated with higher reading scores after three years for children born to mothers with a high school education or less. There is no consistent evidence of an effect on math scores. Overall, these findings suggest broad spillover benefits from health insurance expansions to the well-being and development of children in low-income households that should be part of the continuing policy debate surrounding state and national health insurance reforms.

Effects of Virginia’s 2019 Medicaid Expansion on Health Insurance Coverage, Access to Care, and Health Status

Virginia expanded Medicaid under the Affordable Care Act beginning in January 2019, which substantially increased income eligibility up to 138% of the federal poverty level (FPL) for both childless adults and parents. In this study, we examined the effects of Virginia’s Medicaid expansion in 2019 on health insurance coverage, access to care, and health status by employing a difference-in-differences and a synthetic control design. The study included data on health insurance from the 2016–2020 American Community Survey (ACS) and data on access to care and health status come from the 2016–2020 Behavioral Risk Factors Surveillance System (BRFSS). The samples from ACS and BRFSS were limited to non-elderly adults with income below 138% of the FPL. Separate models were estimated for individuals below 100% of FPL, and those within 100–138% of FPL. The Virginia Medicaid expansion was associated with a 9–11 percentage-point increase in Medicaid coverage rate and a 7–8 percentage-point increase in the insured rate among individuals below 100% FPL, in the first two years of expansion. There was a larger increase in Medicaid coverage among individuals within 100–138% of FPL which also led to a larger increase in the insured rate in 2020. Both income groups showed no changes in private coverage after the expansion in Virginia. We also found a decline in delaying necessary medical visits due to cost for individuals below 100% FPL in 2019 and for individuals within 100–138% FPL in 2020. There was overall no discernable change in health status outcomes. Virginia’s 2019 Medicaid expansion substantially increased insurance coverage among poor adults with suggestive early evidence for improved access. The findings highlight the missed opportunity for other states that have not yet decided to expand their Medicaid programs to improve coverage and access among their low-income individuals.

The Relationship Between Unemployment and Health Insurance Coverage: Before and After the Affordable Care Act's Coverage Expansions

OBJECTIVE

The objective of this study was to determine whether the Affordable Care Act's (ACA) major coverage expansions mitigated the impact of unemployment on health insurance coverage status.

DATA SOURCE

A 2011-2019 versions of the American Community Survey developed by the University of Minnesota Integrated Public Use Microdata Series program.

RESEARCH DESIGN

We use difference-in-difference-in-differences (ie, triple difference) regressions to compare changes in the short-run impacts of local unemployment rates before and after the ACA.

PRINCIPAL FINDINGS

Before the ACA, rises in local unemployment were associated with uninsurance due to losses in private coverage (ie, both nongroup and employer sponsored).Following the ACA's full implementation, the link between employment and coverage was attenuated by access to publicly subsidized qualified health plans on the ACA's nongroup market, and enhanced access to Medicaid in states that expanded. Our findings suggest protections from unemployment-linked uninsured spells are largest in states that expanded Medicaid.

CONCLUSIONS

Expanded access to coverage under the ACA could mitigate the adverse effects on insurance status and access to care historically linked to job loss. However, should the ACA be repealed, many households stand to lose their ability to turn to Medicaid or subsidized nongroup coverage as safety-net resources to offset the burdens of job loss.

Trends in Pediatric Private Insurance and Medicaid Spending: A Repeated Cross-Sectional Analysis of Data from 2002 to 2014

Given increased focus on health spending, this investigation aims to compare trends in pediatric Medicaid and private insurance spending on type of service from 2002 to 2014 in order to inform policy and research. A repeated cross-sectional analysis of 2002 to 2014 National Health Expenditure Accounts data was conducted. Total spending, per capita spending, and compounded annual growth rates for type of service were determined for children ages 0 to 18 at the national level. Per capita spending growth was higher for private insurance than for Medicaid, and the areas of high per capita spending growth differed for private insurance and Medicaid. While Medicaid spent more per capita on hospital care than private insurance, private insurance demonstrated greater per capita spending growth on hospital care than Medicaid (8.49% vs 1.99%, respectively). Conversely, per capita spending on home health care grew more for Medicaid (6.79%) than for private insurance (3.18%). Trends in private insurance and Medicaid overall and per capita spending differ. Medicaid experienced higher annual growth in total spending than per capita spending, while private insurance had greater annual growth in per capita spending than total spending. Growth in private insurance per capita spending was higher than growth in Medicaid per capita spending, but growth in Medicaid total spending was higher than growth in private insurance total spending. These data suggest that Medicaid and private insurance may have different drivers of spending growth, highlighting the need for policy makers to examine spending patterns by payer. Further research to determine why such differences in spending growth exist will better inform efforts to increase health care value.

Heterogeneous Effects of Affordable Care Act Medicaid Expansions Among Women with Dependent Children by State-Level Pre-Expansion Eligibility

Objectives: This study explores the heterogeneity in effects of the 2014 Affordable Care Act (ACA) Medicaid expansions on insurance coverage, health care access, and health status of low-income women with dependent children by pre-expansion state-level income eligibility. Materials and Methods: We employ a quasiexperimental difference-in-differences design comparing outcome changes in Medicaid expansion states to nonexpansion states. We estimate effects separately for three groups of expansion states based on pre-expansion (2013) parent income eligibility: low pre-expansion eligibility (<90% of federal poverty level [FPL]), high eligibility (90% to <138% FPL), and full eligibility (≥138% FPL). Study samples include women with dependent children below 138% FPL from the 2011 to 2018 American Community Survey for the insurance outcomes, and from the 2011 to 2018 Behavioral Risk Surveillance System for the access and health outcomes. Results: There is stark heterogeneity in changes of health insurance and health care access by pre-expansion income eligibility levels. In comparison to Medicaid non-expansion states, there are large increases in insured rate (9 percentage-points) and Medicaid coverage (16 percentage-points) in expansion states with low pre-expansion eligibility. Insurance changes are much smaller in states with high or full pre-expansion eligibility. Changes in access largely mirror those in coverage. There are no significant changes in health status regardless of pre-expansion eligibility. Conclusions: The ACA Medicaid expansions increased coverage and access for low-income women with dependent children primarily in states with low pre-expansion parent eligibility, and therefore, reduced differences in these outcomes between expansion states.

Highly vulnerable communities and the Affordable Care Act: Health insurance coverage effects, 2010-2018

Initially implemented in 2014 in some U.S. states, the Medicaid expansions under the Affordable Care Act (ACA) aimed to make health insurance coverage more accessible to the low-income population. This paper aims to quantify the impact of the ACA Medicaid expansions on insurance coverage among racial/ethnic minorities, immigrants, single mothers, veterans, and low-education whites-i.e., the sectors of the population identified with some of the highest healthcare needs. We focus on individuals 18-64 years of age earning 138% or less of the federal poverty level from the American Community Survey, 2010-2018 (n = 2,927,402). We use difference-in-differences (DD) and difference-in-difference-in-differences (DDD) approaches with propensity scores matched comparison groups to estimate pre-post ACA insurance coverage differences between individuals living in states that participated in the ACA Medicaid expansions and those living in non-participating states, and to estimate if such differences vary across subgroups. We find that insurance coverage rates increased for all subgroups; yet, the ACA benefits have not been evenly distributed across them. Low-education whites, non-Hispanic whites, females, and non-Hispanic Native Americans exhibited the highest improvements in insurance coverage. Our results contribute to the understanding of recent trends in racial and socioeconomic disparities in healthcare and the appropriate policy prescriptions to ameliorate them.

Prevalence and characteristics of HPV vaccine hesitancy among parents of adolescents across the US

BACKGROUND

While many clinicians encounter parents or adolescents who refuse HPV vaccine, little is known about the prevalence of hesitancy for HPV vaccine nationally or its association with vaccination.

METHODS

In April 2019, we surveyed families with adolescents 11-17 years using a national online panel (Knowledge Panel®) as the sampling frame. We assessed the prevalence of HPV vaccine hesitancy with the validated 9-item Vaccine Hesitancy Scale (VHS). We used multivariate analyses to assess demographic factors associated with HPV vaccine hesitancy. We also assessed practical barriers to receipt of HPV vaccine and the relationship between barriers and hesitancy. Finally, we evaluated the association between both HPV vaccine hesitancy and practical barriers on HPV vaccine receipt or refusal.

RESULTS

2,177 parents out of 4,185 sampled (52%) completed the survey, 2,020 qualified (lived with adolescent). Using a VHS cut-off score > 3 out of 5 points, 23% of US parents were hesitant about HPV vaccine. Hesitancy was lower among those with Hispanic ethnicity. At least one out of five parents disagreed that the HPV vaccine is beneficial for their adolescent, that the vaccine is effective, protects against HPV-related cancers, or that they followed their adolescent's health-care provider's recommendation about the vaccine. Many were concerned about vaccine side effects and the novelty of the vaccine. Adolescents living with vaccine-hesitant parents were less than one-third as likely to have received the vaccine (RR = 0.29, 95% CI 0.24, 0.35) or completed the vaccine series (RR = 0.29, 95% CI 0.23, 0.36), and were 6-fold more likely to have refused the vaccine because of parental vaccine-related concerns (RR = 6.09, 95% CI = 5.26, 7.04). Most practical barriers were independently associated with vaccine receipt but not with vaccine refusal.

CONCLUSIONS

HPV vaccine hesitancy is common nationally and strongly related to both under-vaccination and vaccine refusal.

Association of Medicaid Expansion With Insurance Coverage Among Children With Cancer

IMPORTANCE

Despite evidence of improved insurance coverage under the Affordable Care Act and Medicaid expansion among adults with cancer, little is known regarding the association of these policies with coverage among children with cancer.

OBJECTIVE

To assess the association of early Medicaid expansion with rates of Medicaid coverage, private coverage, and no uninsurance among children with cancer.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used data from the Surveillance, Epidemiology, and End Results (SEER) database from January 1, 2007, to December 31, 2015, to identify children diagnosed with cancer at ages 0 to 14 years in the United States. Data were analyzed from July 27, 2017, to October 7, 2019.

EXPOSURES

Changes in insurance status at diagnosis after early Medicaid expansion in California, Connecticut, Washington, and New Jersey (EXP states) were compared with changes in nonexpansion (NEXP) states (Arkansas, Georgia, Hawaii, Iowa, Kentucky, Louisiana, Michigan, New Mexico, and Utah).

MAIN OUTCOMES AND MEASURES

Difference-in-differences (DID) analyses were used to compare absolute changes in insurance status (uninsured, Medicaid, private/other) at diagnosis before (2007 to 2009) and after (2011 to 2015) expansion in EXP relative to NEXP states.

RESULTS

A total of 21 069 children (11 265 [53.5%] male; mean [SD] age, 6.18 [4.57] years) were included. A 5.25% increase (95% CI, 2.61%-7.89%; P < .001) in Medicaid coverage in children with cancer was observed in EXP vs NEXP states, with larger increases among children of counties with middle to high (adjusted DID estimates, 10.18%; 95% CI, 4.22%-16.14%; P = .005) and high (adjusted DID estimates, 6.13%; 95% CI, 1.10%-11.15%; P = .05) poverty levels (P = .04 for interaction). Expansion-associated reductions of children reported as uninsured (-0.73%; 95% CI, -1.49% to 0.03%; P = .06) and with private or other insurance (-4.52%; 95% CI, -7.16% to -1.88%; P < .001) were observed. For the latter, the decrease was greater for children from counties with middle to high poverty (-9.00%; 95% CI, -14.98% to -3.02%) and high poverty (-6.38%; 95% CI, -11.36% to -1.40%) (P = .04 for interaction).

CONCLUSIONS AND RELEVANCE

In this study, state Medicaid expansions were associated with increased Medicaid coverage in children with cancer overall and in some subgroups primarily owing to switching from private coverage, particularly in counties with higher levels of poverty but also through reductions in the uninsured.
