Affordable Care Act-dependent Insurance Coverage and Access to Care Among Young Adult Women With a Recent Live Birth

Reduced odds of severe maternal morbidity associated with the US Affordable Care Act dependent coverage provision

BACKGROUND

Continuous perinatal health insurance coverage is a policy intervention that may help reduce severe maternal morbidity (SMM) and racial and ethnic disparities in SMM in the United States. The Affordable Care Act Dependent Coverage Provision (DCP) allowed young adults to remain on their parent's private health insurance plan until their 26th birthday but its effectiveness in reducing SMM has not been evaluated.

OBJECTIVE

To assess the association of the DCP with SMM during delivery hospitalization.

STUDY DESIGN

Difference-in-differences analysis of US delivery hospitalizations from January 2006 to September 2015, stratified according to maternal race and ethnicity. The outcome was SMM exclusive of blood transfusion only, as defined by the Centers for Disease Control and Prevention criteria. The exposure was maternal age categorized into 21 to 25 years (covered by the DCP) and 27 to 31 years (not covered the DCP). The intervention was the DCP categorized into pre- and post-DCP periods (January 2006-September 2010 and October 2010-September 2015, respectively).

RESULTS

Of the 4,007,937 delivery hospitalizations in the sample, 22,540 (56.2 per 10,000) recorded SMM. For birthing people aged 21 to 25 years (covered by the DCP), the mean SMM rate was 48.9 per 10,000 during the pre-DCP period and 58.2 per 10,000 during the post-DCP period (crude difference: 9.3 per 10,000). For birthing people aged 27 to 31 years (not covered the DCP), the mean SMM rate was 53.4 per 10,000 during the pre-DCP period and 63.6 per 10,000 during the post-DCP period (crude difference: 10.2 per 10,000). Implementation of DCP was associated with a 1.2% (95% CI: -3.6, 1.3) relative decrease in the mean SMM rate (adjusted odds ratio (aOR): 0.988; 95% CI: 0.964, 1.013). For non-Hispanic White people, the DCP was associated with a 10.7% (95% CI: 7.1, 14.2) relative decrease in the mean SMM rate (aOR: 0.893; 95% CI: 0.858, 0.929). The DCP was associated with an increase in the proportion of privately insured (aOR: 1.225; 95% CI: 1.220, 1.231), a decrease in the proportion of Medicaid beneficiaries (aOR: 0.853; 95% CI: 0.849, 0.856), and a decrease in the proportion of uninsured (aOR: 0.807; 95% CI: 0.798, 0.816).

CONCLUSIONS

Maternal health benefit of the DCP appears to be limited to non-Hispanic White birthing people.

Did the Affordable Care Act Promote Racial Equity in Pregnancy-Related Health? A Scoping Review

In the United States, there are profound and persistent racial and ethnic disparities in pregnancy-related health, emphasizing the need to promote racial health equity through public policy. There is evidence that the Affordable Care Act (ACA) increased health insurance coverage, access to health care, and health care utilization, and may have affected some pregnancy-related health outcomes (eg, preterm delivery). It is unclear, however, whether these impacts on pregnancy-related outcomes were equitably distributed across race and ethnicity. Thus, the objective of this study was to fill that gap by summarizing the peer-reviewed evidence regarding the impact of the ACA on racial and ethnic disparities in pregnancy-related health outcomes. The authors conducted a scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR), using broad search terms to identify relevant peer-reviewed literature in PubMed, Web of Science, and EconLit. The authors identified and reviewed n = 21 studies and found that the current literature suggests that the ACA and its components were differentially associated with contraception-related and fertility-related outcomes by race/ethnicity. Literature regarding pregnancy health, birth outcomes, and postpartum health, however, was sparse and mixed, making it difficult to draw conclusions regarding the impact on racial/ethnic disparities in these outcomes. To inform future health policy that reduces racial disparities, additional work is needed to clarify the impacts of contemporary health policy, like the ACA, on racial disparities in pregnancy health, birth outcomes, and postpartum health.

Policy impacts on contraceptive access in the United States: a scoping review

Contraceptive access is influenced by policy decisions, which can expand and constrict the contraceptive options available. This study explored the impact of recent US federal policies on contraceptive access by identifying and reviewing empirical literature, which is then presented and discussed using Levesque et al.’s (2013) healthcare access framework. A scoping review was conducted to identify empirical studies (N = 96) examining the impact of recent federal policy (passed from 2009 to 2019) on contraceptive access. Most identified studies examined the role of the Affordable Care Act (n = 53) and Title X of the Public Health Service Act (n = 25), showing many benefits of both policies for contraceptive access, particularly through improved affordability, availability, and appropriateness of contraceptive care. Other identified studies examined the impact of policies funding abstinence-only sex education (n = 2) and the Teen Pregnancy Prevention Program (n = 3), military policies related to the availability of contraception (n = 1), guidelines for quality contraceptive care (n = 3), Title IX of the Education Amendments (n = 4), the Violence Against Women Act (n = 1), and the Veterans Access, Choice, and Accountability Act (n = 4). Through increased outreach efforts, normalising of care, availability of services, cost subsidies, and provider competencies, recent federal policy has, overall, enhanced contraceptive access across the dimensions of healthcare access. Numerous policy and practice gaps and needs are identified, and future directions for research, policy, and practice are suggested.

Association of Medicaid vs Marketplace Eligibility on Maternal Coverage and Access With Prenatal and Postpartum Care

Importance

Policy makers are considering insurance expansions to improve maternal health. The tradeoffs between expanding Medicaid or subsidized private insurance for maternal coverage and care are unknown.

Objective

To compare maternal coverage and care by Medicaid vs marketplace eligibility.

Design, Setting, and Participants

A retrospective cohort study using a difference-in-difference research design was conducted from March 14, 2020, to April 22, 2021. Maternal coverage and care use were compared among women with family incomes 100% to 138% of the federal poverty level (FPL) residing in 10 Medicaid expansion sites (exposure group) who gained Medicaid eligibility under the Affordable Care Act and in 5 nonexpansion sites (comparison group) who gained marketplace eligibility before (2011-2013) and after (2015-2018) insurance expansion implementation. Participants included women aged 18 years or older from the 2011-2018 Pregnancy Risk Assessment Monitoring System survey.

Exposures

Eligibility for Medicaid or marketplace coverage under the Affordable Care Act.

Main Outcomes and Measures

Outcomes included coverage in the preconception and postpartum periods, early and adequate prenatal care, and postpartum checkups and effective contraceptive use.

Results

The study population included 11 432 women age 18 years and older (32% age 18-24 years, 33% age 25-29 years, 35% age ≥30 years) with incomes 100% to 138% FPL: 7586 in a Medicaid state (exposure group) and 3846 in a nonexpansion marketplace state (comparison group). Women in marketplace states were younger, had higher educational level and marriage rates, and had less racial and ethnic diversity. Medicaid relative to marketplace eligibility was associated with increased Medicaid coverage (20.3 percentage points; 95% CI, 12.8 to 30.0 percentage points), decreased private insurance coverage (-10.8 percentage points; 95% CI, -13.3 to -7.5 percentage points), and decreased uninsurance (-8.7 percentage points; 95% CI, -20.1 to -0.1 percentage points) in the preconception period, increased postpartum Medicaid (17.4 percentage points; 95% CI, 1.7 to 34.3 percentage points) and increased adequate prenatal care (4.4 percentage points; 95% CI, 0.1 to 11.0 percentage points) in difference-in-difference models. No evidence of significant differences in early prenatal care, postpartum check-ups, or postpartum contraception was identified.

Conclusions and Relevance

In this cohort study, eligibility for Medicaid was associated with increased Medicaid, lower preconception uninsurance, and increased adequate prenatal care use. The lower rates of preconception uninsurance among Medicaid-eligible women suggest that women with low incomes were facing barriers to marketplace enrollment, underscoring the potential importance of reducing financial barriers for the population with low incomes.

Association of smoke-free laws with preterm or low birth weight deliveries-A multistate analysis

OBJECTIVE

To assess the association between the change in statewide smoke-free laws and the rate of preterm or low birth weight delivery hospitalizations.

DATA SOURCE

2002-2013 Healthcare Cost and Utilization Project State Inpatient Databases.

STUDY DESIGN

Quasi-experimental difference-in-differences design. We used multivariate logistic models to estimate the association between the change in state smoke-free laws and preterm or low birth weight delivery hospitalizations. The analyses were also stratified by maternal race/ethnicity to examine the differential effects by racial/ethnic groups.

DATA COLLECTION/EXTRACTION METHODS

Delivery hospitalizations among women aged 15-49 years were extracted using the International Classification of Diseases, Ninth Revision, and Diagnosis-Related Group codes.

PRINCIPAL FINDINGS

Non-Hispanic black mothers had a higher rate of preterm or low birth weight delivery hospitalization than other racial/ethnic groups. Overall, there was no association between the change in smoke-free laws and preterm or low birth weight delivery rate. Among non-Hispanic black mothers, the change in statewide smoke-free laws was associated with a 0.9-1.9 percentage point (P < .05) reduction in preterm or low birth weight delivery rate beginning in the third year after the laws took effect. There was no association among non-Hispanic white mothers. A decline in the black-white disparity of 0.6-1.6 percentage points (P < .05) in preterm or low birth weight delivery rates was associated with the change in state smoke-free laws.

CONCLUSION

The change in state smoke-free laws was associated with a reduction in racial/ethnic disparities in preterm or low birth weight delivery hospitalizations in selected US states.

The role of midwifery and other international insights for maternity care in the United States: An analysis of four countries

BACKGROUND

The United States (US) spends more on health care than any other high-resource country. Despite this, their maternal and newborn outcomes are worse than all other countries with similar levels of economic development. Our purpose was to describe maternal and newborn outcomes and organization of care in four high-resource countries (Australia, Canada, the Netherlands, and United Kingdom) with consistently better outcomes and lower health care costs, and to identify opportunities for emulation and improvement in the United States.

METHOD

We examined resources that described health care organization and financing, provider types, birth settings, national, clinical guidelines, health care policies, surveillance data, and information for consumers. We conducted interviews with country stakeholders representing the disciplines of obstetrics, midwifery, pediatrics, neonatology, epidemiology, sociology, political science, public health, and health services. The results of the analysis were compared and contrasted with the US maternity system.

RESULTS

The four countries had lower rates of maternal mortality, low birthweight, and newborn and infant death than the United States. Five commonalities were identified as follows: (1) affordable/ accessible health care, (2) a maternity workforce that emphasized midwifery care and interprofessional collaboration, (3) respectful care and maternal autonomy, (4) evidence-based guidelines on place of birth, and (5) national data collections systems.

CONCLUSIONS

The findings reveal marked differences in the other countries compared to the United States. It is critical to consider the evidence for improved maternal and newborn outcomes with different models of care and to examine US cultural and structural failures that are leading to unacceptable and substandard maternal and infant outcomes.

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.

Specific birth defects in pregnancies of women with diabetes: National Birth Defects Prevention Study, 1997-2011

BACKGROUND

Diabetes is associated with an increased risk for many birth defects and is likely to have an increasing impact on birth defect prevalence because of the rise in diabetes in the United States in recent decades. One of the first analyses in which specific birth defects were assessed for their relationship with both pregestational and gestational diabetes used data from the initial 6 years of the National Birth Defects Prevention Study. That analysis reported strong associations for pregestational diabetes with several birth defects, but few exposures among some of the less common birth defects led to unstable estimates with wide confidence intervals. Since that analysis, the study continued to collect data for another 8 years, including information on approximately 19,000 additional cases and 6900 additional controls.

OBJECTIVE

Our objective was to use data from the National Birth Defects Prevention Study, the largest population-based birth defects case-control study in the United States, to provide updated and more precise estimates of the association between diabetes and birth defects, including some defects not previously assessed.

STUDY DESIGN

We analyzed data on deliveries from October 1997 through December 2011. Mothers of case and control infants were interviewed about their health conditions and exposures during pregnancy, including diagnosis of pregestational (type 1 or type 2) diabetes before the index pregnancy or gestational diabetes during the index pregnancy. Using logistic regression, we separately assessed the association between pregestational and gestational diabetes with specific categories of structural birth defects for which there were at least 3 exposed case infants. For birth defect categories for which there were at least 5 exposed case infants, we calculated odds ratios adjusted for maternal body mass index, age, education, race/ethnicity, and study site; for defect categories with 3 or 4 exposed cases, we calculated crude odds ratios.

RESULTS

Pregestational diabetes was reported by 0.6% of mothers of control infants (71 of 11,447) and 2.5% of mothers of case infants (775 of 31,007). Gestational diabetes during the index pregnancy was reported by 4.7% of mothers of control infants (536 of 11,447) and 5.3% of mothers of case infants (1,653 of 31,007). Pregestational diabetes was associated with strong, statistically significant odds ratios (range, 2.5-80.2) for 46 of 50 birth defects considered. The largest odds ratio was observed for sacral agenesis (adjusted odds ratio, 80.2; 95% confidence interval, 46.1-139.3). A greater than 10-fold increased risk was also observed for holoprosencephaly (adjusted odds ratio, 13.1; 95% confidence interval, 7.0-24.5), longitudinal limb deficiency (adjusted odds ratio, 10.1; 95% confidence interval, 6.2-16.5), heterotaxy (adjusted odds ratio, 12.3; 95% confidence interval, 7.3-20.5), truncus arteriosus (adjusted odds ratio, 14.9; 95% confidence interval, 7.6-29.3), atrioventricular septal defect (adjusted odds ratio, 10.5; 95% confidence interval, 6.2-17.9), and single ventricle complex (adjusted odds ratio, 14.7; 95% confidence interval, 8.9-24.3). For gestational diabetes, statistically significant odds ratios were fewer (12 of 56) and of smaller magnitude (range, 1.3- 2.1; 0.5 for gastroschisis).

CONCLUSION

Pregestational diabetes is associated with a markedly increased risk for many specific births defects. Because glycemic control before pregnancy is associated with a reduced risk for birth defects, ongoing quality care for persons with diabetes is an important opportunity for prevention.

Area-level deprivation and preterm birth: results from a national, commercially-insured population

BACKGROUND

Area-level deprivation is associated with multiple adverse birth outcomes. Few studies have examined the mediating pathways through which area-level deprivation affects these outcomes. The objective of this study was to investigate the association between area-level deprivation and preterm birth, and examine the mediating effects of maternal medical, behavioural, and psychosocial factors.

METHODS

We conducted a retrospective cohort study using national, commercial health insurance claims data from 2011, obtained from the Health Care Cost Institute. Area-level deprivation was derived from principal components methods using ZIP code-level data. Multilevel structural equation modeling was used to examine mediating effects.

RESULTS

In total, 138,487 women with a live singleton birth residing in 14,577 ZIP codes throughout the United States were included. Overall, 5.7% of women had a preterm birth. In fully adjusted generalized estimation equation models, compared to women in the lowest quartile of area-level deprivation, odds of preterm birth increased by 9.6% among women in the second highest quartile (odds ratio (OR) 1.096; 95% confidence interval (CI) 1.021, 1.176), by 11.3% in the third highest quartile (OR 1.113; 95% CI 1.035, 1.195), and by 24.9% in the highest quartile (OR 1.249; 95% CI 1.165, 1.339). Hypertension and infection moderately mediated this association.

CONCLUSIONS

Even among commercially-insured women, area-level deprivation was associated with increased risk of preterm birth. Similar to individual socioeconomic status, area-level deprivation does not have a threshold effect. Implementation of policies to reduce area-level deprivation, and the screening and treatment of maternal mediators may be associated with a lower risk of preterm birth.
