Effect of expanding medicaid for parents on children's health insurance coverage: lessons from the Oregon experiment

Association of state Medicaid expansion policies with pediatric liver transplant outcomes

Children from minoritized/socioeconomically deprived backgrounds suffer disproportionately high rates of uninsurance and graft failure/death after liver transplant. Medicaid expansion was developed to expand access to public insurance. Our objective was to characterize the impact of Medicaid expansion policies on long-term graft/patient survival after pediatric liver transplantation. All pediatric patients (<19 years) who received a liver transplant between January 1, 2005, and December 31, 2020 in the US were identified in the Scientific Registry of Transplant Recipients (N = 8489). Medicaid expansion was modeled as a time-varying exposure based on transplant and expansion dates. We used Cox proportional hazards models to evaluate the impact of Medicaid expansion on a composite outcome of graft failure/death over 10 years. As a sensitivity analysis, we conducted an intention-to-treat analysis from time of waitlisting to death (N = 1 1901). In multivariable analysis, Medicaid expansion was associated with a 30% decreased hazard of graft failure/death (hazard ratio, 0.70; 95% confidence interval, 0.62, 0.79; P < .001) after adjusting for Black race, public insurance, neighborhood deprivation, and living in a primary care shortage area. In intention-to-treat analyses, Medicaid expansion was associated with a 72% decreased hazard of patient death (hazard ratio, 0.28; 95% confidence interval, 0.23-0.35; P < .001). Policies that enable broader health insurance access may help improve outcomes and reduce disparities for children undergoing liver transplantation.

A Qualitative Study of Two Oregon Family Medicine Clinics to Explain Parent and Child Healthcare Initiation and Engagement

Background: Parental factors are associated with children's receipt of recommended care but not adequately described. Methods: We conducted a qualitative study of patients with at least two visits who were a primary caregiver for a child who also had at least two visits at the same clinic in 1/2018-12/2019 from two Oregon family medicine clinics. We stratified patients by child age and number of caregiver visits and randomly selected caregivers. Participants were interviewed in accordance with approval by our Institutional Review Board between 12/2020 and 4/2021. The data were analyzed using a grounded theory approach. Results: 12 caregivers (termed parents) were interviewed; half were single parents and three-quarters had a history of substance use disorder and/or a mental health condition. Parents focused on the importance of keeping themselves healthy to keep their families healthy. They described similar reasons for choosing to initiate and continue care for themselves and their children at the same clinic, including: convenience, trust, relationships, and receiving whole-person and whole-family care. Many valued having a healthcare "home" for their entire family. We developed a figure that highlights three themes that capture the interrelated factors parents identified as supporting healthcare use for themselves and their families. These overarching themes included: healthcare initiation; healthcare engagement and continuity; and parent bringing child to the same clinic for healthcare. Conclusion: Our data suggests that long-standing patient-clinic relationships for parents and children can support family-focused healthcare.

An observational study of health insured visits for children following Medicaid eligibility expansion for adults among a linked cohort of parents and children

Despite its focus on adults, the Affordable Care Act (ACA) Medicaid expansion led to increased health insurance enrollment for children in the United States. Previous studies looked at parent and child insurance changes separately, or used a single survey response item to understand changes in health insurance for parents and children. It is, however, important to understand the connection between parent and child insurance changes together (not individually) using data sources that account for insurance over time. Therefore, to understand the association of parental health insurance on their children's coverage, leveraging a cohort of linked families seen in community health centers (CHCs), we used electronic health records to link a cohort of parents and children with ≥1 visit to a CHC in a Medicaid expansion state pre- (1/1/2012-12/31/2013) and ≥1 visit post-ACA (1/1/2014-12/31/2018) and determined primary payer type for all visits. This observational, cohort study assessed the rate of insured visits for children pre- to post-ACA across four parental insurance groups (always insured, gained Medicaid, discontinuously insured, never insured) using Poisson mixed effects models. We included 335 CHCs across 7 United States. Insurance rates were highest (~95 insured visits/100 visits) for children of parents who were always insured; rates were lowest for children of parents who were never insured (~83 insured visits/100 visits). Children with a parent who gained Medicaid had 4.4% more insured visits post- compared to pre-ACA (adjusted relative rates  = 1.044, 95% confidence interval: 1.014, 1.074). When comparing changes from pre- to post-ACA between parent insurance groups, children's insured visit rates were significantly higher for children of parents who gained Medicaid (reference) compared to children of parents who were always insured (adjusted ratio of rate ratio: 0.963, confidence interval: 0.935-0.992). Despite differences in Medicaid eligibility for children and adults, health insurance patterns were similar for linked families seen in CHCs. Findings suggest consideration should be paid to parent health insurance options when trying to increase children's coverage.

Out of the Woodwork: Enrollment Spillovers in the Oregon Health Insurance Experiment

We analyze the impact of expanded adult Medicaid eligibility on the enrollment of already-eligible children. We analyze the 2008 Oregon Medicaid lottery, in which some low-income uninsured adults were randomly selected to be allowed to apply for Medicaid. Children in these households were eligible for Medicaid irrespective of the lottery outcome. We estimate statistically significant but transitory impacts of adult lottery selection on child Medicaid enrollment: at three months after the lottery, for every 9 adults who enrolled in Medicaid due to winning the lottery, one additional child also enrolled. Our results shed light on the existence, magnitude, and nature of so-called "woodwork effects".

Narrowing Insurance Disparities Among Children and Adolescents With Cancer Following the Affordable Care Act

Despite advances toward universal health insurance coverage for children, coverage gaps remain. Using a nationwide sample of pediatric and adolescent cancer patients from the National Cancer Database, we examined effects of the Affordable Care Act (ACA) implementation in 2014 with multinomial logistic regressions to evaluate insurance changes between 2010-2013 (pre-ACA) and 2014-2017 (post-ACA) in patients aged younger than 18 years (n = 63 377). All statistical tests were 2-sided. Following the ACA, the overall percentage of Medicaid and Children's Health Insurance Program-covered patients increased (from 35.1% to 36.9%; adjusted absolute percentage change [APC] = 2.01 percentage points [ppt], 95% confidence interval [CI] = 1.31 to 2.71; P < .001), partly offset by declined percentage of privately insured (from 62.7% to 61.2%; adjusted APC = -1.67 ppt, 95% CI = -2.37 to -0.97; P < .001), leading to a reduction by 15% in uninsured status (from 2.2% to 1.9%; adjusted APC = -0.34 ppt, 95% CI = -0.56 to -0.12 ppt; P = .003). The largest declines in uninsured status were observed among Hispanic patients (by 23%; adjusted APC = -0.95 ppt, 95% CI = -1.67 to -0.23 ppt; P = .009) and patients residing in low-income areas (by 35%; adjusted APC = -1.22 ppt, 95% CI = -2.22 to -0.21 ppt; P = .02). We showed nationwide insurance gains among pediatric and adolescent cancer patients following ACA implementation, with greater gains in racial and ethnic minorities and those living in low-income areas.

Creation of a linked cohort of children and their parents in a large, national electronic health record dataset

To examine which parental health care and health factors are most strongly associated with a child's receipt of recommended care we must be able to link children to their parents in electronic health record data. Yet, there is not an easy way to link these data.To identify a national cohort of children that link to at least one parent in the same electronic health record dataset and describe their demographics.Methodology to link parents and children in electronic health records and descriptive sociodemographic data.Children with at least one encounter with a primary care clinician between Januray 1, 2007 and December 12, 2018 to a community health center in the OCHIN national network. We identified parents of these children who also had at least one encounter to a community health center in the network using emergency contact and guarantor record fields.A total of 227,552 children had parents with a linkable patient record. After exclusions, our final cohort included 213,513 distinct children with either one or two parent-links. 82% of children linked to a mother only, 14% linked to a father only, and 4% linked to both a mother and a father. Most families consisted of only one linked child (61%).We were able to link 33% of children to a parent in electronic health record data from a large network of community health centers across the United States. Further analyses utilizing these linkages will allow examination of the multi-level factors that impact a child's receipt of recommended health care.

Brief Report: Medicaid Expansion and Growth in the Workforce for Autism Spectrum Disorder

Over 700,000 children throughout the U.S. have received insurance coverage through welcome mat effects of Medicaid expansion, including children with autism spectrum disorder (ASD). Utilizing health workforce data from the Health Resources and Services Administration, we examined workforce growth (2008-2017) among three types of health providers for children with ASD as a result of Medicaid expansion: child psychiatrists, board-certified behavioral analysts (BCBAs) and pediatricians. We found that state Medicaid expansion was associated with a 9% increase in BCBAs per 100,000 children one year after enactment, a 5% increase in child psychiatrists, and was not associated with growth in pediatricians. Results indicate the importance of new policies that directly address a shortage of providers for children with ASD.

Adult Medicaid benefit generosity and receipt of recommended health services among low-income children: The spillover effects of Medicaid adult dental coverage expansions

Low-income children are less likely to receive recommended health services than their high-income counterparts. This paper examines whether the design of parental Medicaid benefit packages could serve as a mechanism for reducing income-based disparities in unmet health care needs, considering dental benefits as a case study. Leveraging state-level changes to adult dental benefits over time, I find that coverage is associated with increases of 14 and 5 percentage points, respectively, in the likelihood of a recent dental visit among parents and children directly exposed to the policy. Child effects appear to be concentrated among younger children under age 12.

Children's dental service use reflects their parents' dental service experience and insurance

BACKGROUND

Decisions about children's oral health care are made by parents. Parents' dental insurance, dental service use, and perceived affordability all influence their children's oral health care.

METHODS

Using data from the 2016 National Health Interview Survey, the authors constructed a database of 4,396 nationally representative US children and their linked household adults. The authors assessed the relationship between children's and parents' use of dental services, private and public dental insurance, and deferral of oral health care owing to cost. To adjust for factors that may influence outcomes independently, the authors performed multivariate analyses to consider child, parent, and household characteristics.

RESULTS

Children have 2 times the risk of lacking a dental visit in a year if the parent has none, 7 times the risk of reportedly lacking dental coverage if the parent has none, and nearly 10 times the risk of having care deferred owing to cost if the parent finds oral health care unaffordable. Affordability risk factors for children include older age and minority race, whereas protective factors include public insurance, parents with higher educational attainment, and female-led households. Increased oral health care use by children was associated with states that provide more extensive adult Medicaid dental benefits.

CONCLUSIONS

Greater parental dental service use, dental coverage, and ability to afford care benefit their children's use of oral health care.

PRACTICE IMPLICATIONS

Policies by employers and government that expand quality private and public coverage for adults hold strong promise to improve oral health care for both parents and their children.

Changes in Health Care-Related Financial Burden for US Families With Children Associated With the Affordable Care Act

Importance

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.

Objective

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.

Design, Setting, and Participants

Data used for this cohort study were obtained from the 2000-2017 Medical Expenditure Panel Survey, a nationally representative, population-based survey. Multivariable regression with a difference-in-differences estimator was used to examine changes in family financial burden before and after ACA implementation according to income-based ACA eligibility groups (≤138% [lowest-income], 139%-250% [low-income], 251%-400% [middle-income], and >400% [high-income] federal poverty level). The cohort included 92 165 families with 1 or more children (age ≤18 years) and 1 or more adult parents/guardians.

Exposures

Income-based eligibility groups during post-ACA years (calendar years 2014-2017) vs pre-ACA years (calendar years 2000-2013).

Main Outcomes and Measures

Family annual out-of-pocket (OOP) health care and premium cost burden relative to income. High OOP burden was determined based on a previously validated algorithm with relative cost thresholds that vary across incomes, and extreme OOP burden was defined as costs exceeding 10% of income. Premiums exceeding 9.5% of income were classified as burdensome and premiums relative to median household income defined an unaffordability index.

Results

Compared with high-income families who experienced a lesser change post-ACA implementation (high OOP burden, 1.1% pre-ACA vs 0.9% post-ACA), the lowest-income families saw the greatest reduction in high OOP burden (35.6% pre-ACA vs 23.7% post-ACA; difference-in-differences: -11.4%; 95% CI, -13.2% to -9.5%) followed by low-income families (24.6% pre-ACA vs 17.3% post-ACA, difference-in-differences: -6.8%; 95% CI, -8.7% to -4.9%) and middle-income families (6.1% pre-ACA vs 4.6% post-ACA, difference-in-differences: -1.2%; 95% CI, -2.3% to -0.01%). Although premiums rose for all groups, premium unaffordability was the least exacerbated for the lowest-, low-, and middle-income families compared with higher-income families.

Conclusions and Relevance

The findings of this study suggest that low- and middle-income families with children who were eligible for ACA Medicaid expansions and Marketplace subsidies experienced greater reductions in health care-related financial burden after the ACA was implemented compared with families with higher incomes. However, despite ACA policies, many low- and middle-income families with children appear to continue to face considerable financial burden from premiums and OOP costs.

Association between Medicaid expansion, dental coverage policies for adults, and children's receipt of preventive dental services

OBJECTIVE

To examine 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.

DATA SOURCES

Medical Expenditure Panel Survey (2011-2016), Area Health Resources File, and Medicaid adult dental coverage policies.

STUDY DESIGN

We conducted a quasi-experimental analysis using linked parent-child dyads in low-income families (≤125 percent of the Federal Poverty Level). We assessed whether expansions of Medicaid to low-income adults under the Affordable Care Act were associated with increases in the use of preventive dental services among low-income children when state Medicaid programs did vs did not cover these services for adults.

PRINCIPAL FINDINGS

Over the study period, 37.8 percent of low-income children received at least one annual preventive dental visit. We found no change in children's receipt of preventive dental care associated with Medicaid expansions in states that covered (1.26 percentage points; 95% CI: -3.74 to 6.27) vs did not cover preventive dental services for adults (3.03 percentage points; 95% CI: -2.76 to 8.81). (differential change: -1.76 percentage points; 95% CI: -8.09, 4.56). However, our estimates are imprecise, with wide confidential intervals that are unable to rule out sizable effects in either direction.

CONCLUSION

We did not find an association between Medicaid expansions with concurrent coverage of preventive dental services for adults and children's use of these services. 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 maternal characteristics with latino youth health insurance disparities in the United States: a generalized structural equation modeling approach

Background

Disparities in access to care persist for Latino youth born in the United States (US). The association of maternal characteristics, such as maternal citizenship status and insurance coverage, on youth health insurance coverage is unclear and is important to examine given the recent sociopolitical shifts occurring in the US.

Methods

We analyzed pooled cross-sectional data from the 2010–2018 National Health Interview Survey to examine the association of Latina maternal citizenship status on maternal insurance coverage status and youth uninsurance among US-born Latino youth. Our study sample consisted of 15,912 US-born Latino youth (ages < 18) with linked mothers. Our outcome measures were maternal insurance coverage type and youth uninsurance and primary predictor was maternal citizenship status. Generalized structural equation modeling was used to examine the relationships between maternal characteristics (maternal citizenship, maternal insurance coverage status) and youth uninsurance.

Results

Overall, 7% of US-born Latino youth were uninsured. Just 6% of youth with US-born mothers were uninsured compared to almost 10% of those with noncitizen mothers. Over 18% of youth with uninsured mothers were uninsured compared to 2.2% among youth with mothers who had private insurance coverage. Compared to both US-born and naturalized citizen Latina mothers, noncitizen Latina mothers had 4.75 times the odds of reporting being uninsured. Once adjusted for predisposing, enabling, and need factors, maternal uninsurance was strongly associated with youth uninsurance and maternal citizenship was weakly associated with youth uninsurance among US-born Latino youth.

Conclusion

Maternal citizenship was associated with both maternal uninsurance and youth uninsurance among US-born Latino youth. Federal- and state-level health policymaking should apply a two-generational approach to ensure that mothers of children are offered affordable health insurance coverage, regardless of their citizenship status, thus reducing uninsurance among US-born Latino youth.

Insurance Coverage and Health Care Utilization Among Asian Youth Before and After the Affordable Care Act

OBJECTIVE

We examined changes in insurance coverage and health care utilization associated with the Affordable Care Act (ACA) among subgroups of Asian youth relative to non-Latino white youth.

METHODS

Data were from the 2010 to 2017 American Community Survey and National Health Interview Survey. Difference-in-difference models were used to examine changes in insurance coverage and health care utilization associated with the ACA among subgroups of Asian youth relative to white youth and subgroups of Asian youth in households below 200% of the federal poverty level relative to comparable white youth.

RESULTS

Since the implementation of the ACA, insurance coverage increased among all Asian subgroups and white youth. The magnitude of the increase in insurance coverage was larger among Asian subgroups than white youth. More pronounced increases were found among almost all Asian subgroups in households below 200% federal poverty level. Changes in health care utilization were limited and varied by subgroup. Increases in well-child visits were observed only among Chinese and "other" Asian youth.

CONCLUSIONS

Insurance coverage increased among Asian youth after the implementation of the ACA. Improvements in health care utilization were limited and differed by subgroups. Programs to improve health care utilization should be tailored to Asian youth according to subgroup.

Pediatric outpatient utilization by differing Medicaid payment models in the United States

BACKGROUND

In the United States (US), Medicaid capitated managed care costs are controlled by optimizing patients' healthcare utilization. Adults in capitated plans utilize primary care providers (PCP) more than emergency departments (ED), compared to fee-for-service (FFS). Pediatric data are lacking. We aim to determine the association between US capitated and FFS Medicaid payment models and children's outpatient utilization.

METHODS

This retrospective cohort compared outpatient utilization between two payment models of US Medicaid enrollees aged 1-18 years using Truven's 2014 Marketscan Medicaid database. Children enrolled > 11 months were included, and were excluded for eligibility due to disability/complex chronic condition, lack of outpatient utilization, or provider capitation penetration rate < 5% or > 95%. Negative binomial and logistic regression assessed relationships between payment model and number of visits or odds of utilization, respectively.

RESULTS

Of 711,008 children, 66,980(9.4%) had FFS and 644,028(90.6%) had capitated plans. Children in capitated plans had greater odds of visits to urgent care, PCP-acute, and PCP-well-child care (aOR 1.21[95%CI 1.15-1.26]; aOR 2.07[95%CI 2.03-2.13]; aOR 1.86 [95%CI 1.82-1.91], respectively), and had lower odds of visits to EDs and specialty care (aOR 0.82 [95%CI 0.8-0.83]; aOR 0.61 [95%CI 0.59-0.62], respectively), compared to FFS.

CONCLUSIONS

The majority of children in this US Medicaid population had capitated plans associated with higher utilization of acute care, but increased proportion of lower-cost sites, such as PCP-acute visits and UC. Health insurance programs that encourage capitated payment models and care through the PCP may improve access to timely acute care in lower-cost settings for children with non-complex chronic conditions.

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.

ACA Medicaid Expansion and Insurance Coverage Among New Mothers Living in Poverty

BACKGROUND

Medicaid plays a critical role during the perinatal period, but pregnancy-related Medicaid eligibility only extends for 60 days post partum. In 2014, the Affordable Care Act's (ACA's) Medicaid expansions increased adult Medicaid eligibility to 138% of the federal poverty level in participating states, allowing eligible new mothers to remain covered after pregnancy-related coverage expires. We investigate the impact of ACA Medicaid expansions on insurance coverage among new mothers living in poverty.

METHODS

We define new mothers living in poverty as women ages 19 to 44 with incomes below the federal poverty level who report giving birth in the past 12 months. We use 2010-2017 American Community Survey data and a difference-in-differences approach using parental Medicaid-eligibility thresholds to estimate the effect of ACA Medicaid expansions on insurance coverage among poor new mothers.

RESULTS

A 100-percentage-point increase in parental Medicaid-eligibility is associated with an 8.8-percentage-point decrease (P < .001) in uninsurance, a 13.2-percentage-point increase (P < .001) in Medicaid coverage, and a 4.4-percentage-point decrease in private or other coverage (P = .001) among poor new mothers. The average increase in Medicaid eligibility is associated with a 28% decrease in uninsurance, a 13% increase in Medicaid coverage, and an 18% decline in private or other insurance among poor new mothers in expansion states. However, in 2017, there were ∼142 000 remaining uninsured, poor new mothers.

CONCLUSIONS

ACA Medicaid expansions are associated with increased Medicaid coverage and reduced uninsurance among poor new mothers. Opportunities remain for expansion and nonexpansion states to increase insurance coverage among new mothers living in poverty.

State-Level Immigrant Prenatal Health Care Policy and Inequities in Health Insurance Among Children in Mixed-Status Families

Children in immigrant families are twice as likely to be uninsured as their counterparts, and states may influence these inequities by facilitating or restricting immigrant families' access to coverage. Our objective was to measure differences in insurance by mother's documentation status among a nationally representative sample of US-born children in immigrant families and to examine the role of state-level immigrant health care policy-namely, state-level immigrant access to prenatal coverage. Compared with US-born children in immigrant families with citizen mothers, children with undocumented immigrant mothers had a 17.0 percentage point (P < .001) higher uninsurance rate (8.8 percentage points higher in adjusted models, P < .05). However, in states with nonrestrictive prenatal coverage for immigrants, there were no differences in children's insurance by mother's documentation status, while large inequities were observed within states with restrictive policies. Our findings demonstrate the potential for state-level immigrant health care policy to mitigate or exacerbate inequities in children's insurance.

Medicaid and CHIP Child Health Beneficiary Incentives: Program Landscape and Stakeholder Insights

OBJECTIVES

To describe the landscape of Medicaid and the Children's Health Insurance Program beneficiary incentive programs for child health and garner key stakeholder insights on incentive program rationale, child and family engagement, and program evaluation.

METHODS

We identified beneficiary health incentive programs from 2005 to 2018 through a search of peer-reviewed and publicly available documents and through semistructured interviews with 80 key stakeholders (Medicaid and managed-care leadership, program evaluators, patient advocates, etc). This study highlights insights from 23 of these stakeholders with expertise on programs targeting child health (<18 years old) to understand program rationale, beneficiary engagement, and program evaluation.

RESULTS

We identified 82 child health-targeted beneficiary incentive programs in Medicaid and the Children's Health Insurance Program. Programs most commonly incentivized well-child checks (n = 77), preventive screenings (n = 30), and chronic disease management (n = 30). All programs included financial incentives (eg, gift cards, premium incentives); some also offered incentive material prizes (n = 12; eg, car seats). Loss-framed incentives were uncommon (n = 1; eg, lost benefits) and strongly discouraged by stakeholders. Stakeholders suggested family engagement strategies including multigenerational incentives or incentives addressing social determinants of health. Regarding evaluation, stakeholders suggested incentivizing evidence-based preventive services (eg, vaccinations) rather than well-child check attendance, and considering proximal measures of child well-being (eg, school functioning).

CONCLUSIONS

As the landscape of beneficiary incentive programs for child health evolves, policy makers have unique opportunities to leverage intergenerational and social approaches for family engagement and to more effectively increase and evaluate programs' impact.

Adult-Oriented Health Reform and Children's Insurance and Access to Care: Evidence from Massachusetts Health Reform

Objective A national debate is underway about the value of key provisions within the adult-oriented Affordable Care Act (ACA)-the individual mandate, expansion of Medicaid eligibility, and essential benefits. How these provisions affect child health insurance and access to care may help us anticipate how children may be affected if the ACA is repealed. We study Massachusetts health reform because it enacted these key provisions statewide in 2006. Methods We used a difference-in-differences (DD) approach to assess the impact of Massachusetts health reform on uninsurance and access to care among children 0-17 years in Massachusetts compared to children in other New England states. The National Survey of Children's Health provided the pre-reform year and two post-reform years (1 and 5 years post-reform). We analyzed outcomes for children overall and children previously and newly-eligible for Medicaid under Massachusetts health reform, adjusting for age, sex, race/ethnicity, non-English language, and having special health care needs. Results Compared to other New England states, Massachusetts's enactment of the individual mandate, Medicaid expansion, and essential benefits was associated with trends at 5 years post-reform toward lower uninsurance for children overall (DD = - 1.1, p-for-DD = 0.05), increased access to specialty care (DD = 7.7, p-for-DD = 0.06), but also with a decrease in access to preventive care (DD=-3.4, p-for-DD = 0.004). At 1 year post-reform, access to specialty care improved for children newly-Medicaid-eligible (DD = 18.3, p-for-DD = 0.03). Conclusions for Practice Adult-oriented health reforms may have reduced uninsurance and improved access to some types of care for children in Massachusetts. Repealing the ACA may produce modest detriments for children.

Early Impact of the Patient Protection and Affordable Care Act on Delivery of Children's Surgical Care

The impact of the Patient Protection and Affordable Care Act (PPACA) on children's access to surgical care is not well-defined. Our objective was to describe the early impact of PPACA on children's surgical care before and after Medicaid expansion in 2014. We compared pediatric and young adult surgical outcomes in 2013 and 2014 in Medicaid expansion and nonexpansion states; young adults were included as a control group. From 4 states, 1 597 708 encounters met all inclusion criteria. Comparing expansion to nonexpansion states, modest increases were noted in elective instead of urgent/emergent admissions; in ambulatory instead of inpatient surgeries; in inpatient length of stays; in discharges to home instead of other inpatient care facilities; and in charges for inpatient admissions. A modest decrease of -1.1% was noted in ambulatory admission charges. Overall, we conclude that Medicaid expansion likely increased children's access to surgical care, resulting in improved delivery and slightly reduced charges.

Maternal and child patterns of Medicaid retention: a prospective cohort study

BACKGROUND

We sought to determine whether maternal Medicaid retention influences child Medicaid retention because caregivers play a critical role in assuring children's health access.

METHODS

We conducted a longitudinal prospective cohort study of a convenience sample of 604 Medicaid-eligible mother-child dyads followed from the infant's birth through 24 months of age with parent surveys. Individual enrollment status was abstracted from administrative Medicaid eligibility files. Generalized estimating equations quantified the effect of maternal Medicaid enrollment status on child Medicaid retention, adjusting for relevant covariates. Because varying lengths of gaps may have different effects on child health outcomes, Medicaid enrollment status was further categorized by length of gap: any gap, > 14-days, and > 60-days.

RESULTS

This cohort consists primarily of African-American (94%), unmarried mothers (88%), with a mean age of 23.2 years. In multivariable analysis, children whose mothers experienced any gaps in coverage had 12.6 times greater odds of experiencing gaps when compared to children whose mothers were continuously enrolled. Use of varying thresholds to define coverage gaps resulted in similar odds ratios (> 14-day gap = 11.8, > 60-day gap = 16.8). Cash assistance receipt and maternal knowledge of differences between Temporary Assistance to Needy Families and Medicaid eligibility criteria demonstrated strong protective effects against child Medicaid disenrollment.

CONCLUSIONS

Medicaid disenrollment remains a significant policy problem and maternal Medicaid retention patterns show strong effects on child Medicaid retention. Policymakers need to invest in effective outreach strategies, including family-friendly application processes, to reduce enrollment barriers so that all eligible families can take advantage of these coverage opportunities.

Spillover Effects of Adult Medicaid Expansions on Children's Use of Preventive Services

BACKGROUND

Since the passage of the Affordable Care Act, Medicaid enrollment has increased by ∼17 million adults, including many low-income parents. One potentially important, but little studied, consequence of expanding health insurance for parents is its effect on children's receipt of preventive services.

METHODS

By using state Medicaid eligibility thresholds linked to the 2001-2013 Medical Expenditure Panel Surveys, we assessed the relationship between changes in adult Medicaid eligibility and children's likelihood of receiving annual well-child visits (WCVs). In instrumental variable analyses, we used these changes in Medicaid eligibility to estimate the relationship between parental enrollment in Medicaid and children's receipt of WCVs.

RESULTS

Our analytic sample consisted of 50 622 parent-child dyads in families with incomes <200% of the federal poverty level, surveyed from 2001 to 2013. On average, a 10-point increase in a state's parental Medicaid eligibility (measured relative to the federal poverty level) was associated with a 0.27 percentage point higher probability that a child received an annual WCV (95% confidence interval: 0.058 to 0.48 percentage points, P = .012). Instrumental variable analyses revealed that parental enrollment in Medicaid was associated with a 29 percentage point higher probability that their child received an annual WCV (95% confidence interval: 11 to 47 percentage points, P = .002).

CONCLUSIONS

In our study, we demonstrate that Medicaid expansions targeted at low-income adults are associated with increased receipt of recommended pediatric preventive care for their children. This finding reveals an important spillover effect of parental insurance coverage that should be considered in future policy decisions surrounding adult Medicaid eligibility.

The Impact of Single Mothers' Health Insurance Coverage on Behavioral Health Services Utilization by Their Adolescent Children

Adolescents living in single-mother households are more likely to have behavioral health conditions, but are less likely to utilize any behavioral health services. Using nationally representative mother-child pair data pooled over 6 years from the National Survey on Drug Use and Health, the study finds that when single mothers were uninsured, their adolescent children were less likely to utilize any behavioral health services, even when the children themselves were covered by insurance. The extension of health coverage under the Affordable Care Act (ACA) to uninsured single mothers could improve the behavioral health of the adolescent population.

Protocol for the analysis of a natural experiment on the impact of the Affordable Care Act on diabetes care in community health centers

Background

It is hypothesized that Affordable Care Act (ACA) Medicaid expansions could substantially improve access to health insurance and healthcare services for patients at risk for diabetes mellitus (DM), with pre-DM, or already diagnosed with DM. The ACA called for every state to expand Medicaid coverage by 2014. In a 2012 legal challenge, the US Supreme Court ruled that states were not required to implement Medicaid expansions. This 'natural experiment' presents a unique opportunity to learn whether and to what extent Medicaid expansion can affect healthcare access and services for patients with DM risk, pre-DM, or DM.

Methods/design

Data from electronic health records (EHRs) from the Accelerating Data Value Across a National Community Health Center Network (ADVANCE) clinical data research network, which has data from >700 community health centers (CHCs), was included in the study. EHR data will be linked to Oregon Medicaid claims data. Data collection will include information on changes in health insurance, service receipt, and health outcomes, spanning 9 years (pre- and post-expansion), comparing states that expanded Medicaid, and those that did not. Patients included in this study will be diagnosed with DM, be at risk for DM, or have pre-DM, between the ages of 19 and 64, with ≥1 ambulatory visit. Sample size is estimated to be roughly 275,000 patients. Biostatistical analyses will include the difference-in-differences (DID) methodology and a generalized linear mixed model. Econometric analyses will include a DID two-part method to calculate the difference in Medicaid expenditures in Oregon among newly insured CHC patients.

Discussion

Findings will have national relevance on DM health services and outcomes and will be shared through national conferences and publications. The findings will provide information needed to impact the policy as it is related to access to health insurance and receipt of healthcare among a vulnerable population.

Off to the Right Start: Well-Child Visit Attendance Among Health Center Users

INTRODUCTION

This study examines correlates of past-year well-child visit attendance, reasons for choosing to receive care at a health center, and patient experience among pediatric federally qualified health center users.

METHOD

This observational study used cross-sectional 2009 Health Center Patient Survey data. Descriptive statistics, bivariate analysis, and multivariable models were utilized.

RESULTS

This study found that 83.0% of children who visited a health center in the past year had a well-child visit in the past year and 88.5% had a usual source of care, with no disparities based on race/ethnicity or insurance status. A usual source of care, especially a health center, enhanced well-child visit attendance. The top reasons for seeking care at a health center include convenience (31.6%), quality (24.5%), accessibility (17.7%), and co-located nonmedical services (11.5%).

DISCUSSION

Well-child visit attendance is high but there is room for improvement, particularly among patients who lack a usual source of care.

The Role of Public Health Insurance in Reducing Child Poverty

Over the past 30 years, there have been major expansions in public health insurance for low-income children in the United States through Medicaid, the Children's Health Insurance Program (CHIP), and other state-based efforts. In addition, many low-income parents have gained Medicaid coverage since 2014 under the Affordable Care Act. Most of the research to date on health insurance coverage among low-income populations has focused on its effect on health care utilization and health outcomes, with much less attention to the financial protection it offers families. We review a growing body of evidence that public health insurance provides important financial benefits to low-income families. Expansions in public health insurance for low-income children and adults are associated with reduced out of pocket medical spending, increased financial stability, and improved material well-being for families. We also review the potential poverty-reducing effects of public health insurance coverage. When out of pocket medical expenses are taken into account in defining the poverty rate, Medicaid plays a significant role in decreasing poverty for many children and families. In addition, public health insurance programs connect families to other social supports such as food assistance programs that also help reduce poverty. We conclude by reviewing emerging evidence that access to public health insurance in childhood has long-term effects for health and economic outcomes in adulthood. Exposure to Medicaid and CHIP during childhood has been linked to decreased mortality and fewer chronic health conditions, better educational attainment, and less reliance on government support later in life. In sum, the nation's public health insurance programs have many important short- and long-term poverty-reducing benefits for low-income families with children.

Trends in Type of Health Insurance Coverage for US Children and Their Parents, 1998-2011

OBJECTIVE

To examine trends in health insurance type among US children and their parents.

METHODS

Using the Medical Expenditure Panel Survey (1998-2011), we linked each child (n = 120,521; weighted n ≈ 70 million) with his or her parent or parents and assessed patterns of full-year health insurance type, stratified by income. We examined longitudinal insurance trends using joinpoint regression and further explored these trends with adjusted regression models.

RESULTS

When comparing 1998 to 2011, the percentage of low-income families with both child and parent or parents privately insured decreased from 29.2% to 19.1%, with an estimated decline of -0.86 (95% confidence interval, -1.10, -0.63) unadjusted percentage points per year; middle-income families experienced a drop from 74.5% to 66.3%, a yearly unadjusted percentage point decrease of -0.73 (95% confidence interval, -0.98, -0.48). The discordant pattern of publicly insured children with uninsured parents increased from 10.4% to 27.2% among low-income families and from 1.4% to 6.7% among middle-income families. Results from adjusted models were similar to joinpoint regression findings.

CONCLUSIONS

During the past decade, low- and middle-income US families experienced a decrease in the percentage of child-parent pairs with private health insurance and pairs without insurance. Concurrently, there was a rise in discordant coverage patterns-mainly publicly insured children with uninsured parents.

Trends in Disparities in Low-Income Children's Health Insurance Coverage and Access to Care by Family Immigration Status

OBJECTIVE

To examine time trends in disparities in low-income children's health insurance coverage and access to care by family immigration status.

METHODS

We used data from the National Survey of Children's Health in 2003 to 2011-2012, including 83,612 children aged 0 to 17 years with family incomes <200% of the federal poverty level. We examined 3 immigration status categories: citizen children with nonimmigrant parents; citizen children with immigrant parents; and immigrant children. We used multivariable regression analyses to obtain adjusted trends in health insurance coverage and access to care.

RESULTS

All low-income children experienced gains in health insurance coverage and access to care from 2003 to 2011-2012, regardless of family immigration status. Relative to citizen children with nonimmigrant parents, citizen children with immigrant parents had a 5 percentage point greater increase in health insurance coverage (P = .06), a 9 percentage point greater increase in having a personal doctor or nurse (P < .01), and an 11 percentage point greater increase in having no unmet medical need (P < .01). Immigrant children had significantly lower health insurance coverage than other groups. However, the group had a 14 percentage point greater increase in having a personal doctor or nurse (P < .01) and a 26 percentage point greater increase in having no unmet medical need (P < .01) relative to citizen children with nonimmigrant parents.

CONCLUSIONS

Some disparities in access to care related to family immigration status have lessened over time among children in low-income families, although large disparities still exist. Policy efforts are needed to ensure that children of immigrant parents and immigrant children are able to access health insurance and health care.

IMPACCT Kids' Care: a real-world example of stakeholder involvement in comparative effectiveness research

The Patient-Centered Outcomes Research Institute has accelerated conversations about the importance of actively engaging stakeholders in all aspects of comparative effectiveness research (CER). Other scientific disciplines have a history of stakeholder engagement, yet few empirical examples exist of how these stakeholders can inform and enrich CER. Here we present a case study which includes the methods used to engage stakeholders, what we learned from them, and how we incorporated their ideas in a CER project. We selected stakeholders from key groups, built relationships with them and collected their feedback through interviews, observation and ongoing meetings during the four research process phases: proposal development, adapting study methods, understanding the context and information technology tool design and refinement.
