Racial and Ethnic Disparities in Perinatal Insurance Coverage

Correlates of Insulin Selection as a First-Line Pharmacological Treatment for Gestational Diabetes

OBJECTIVE

The aim of this study was to investigate prenatal factors associated with insulin prescription as a first-line pharmacotherapy for gestational diabetes mellitus (GDM; compared with oral antidiabetic medication) after failed medical nutrition therapy.

STUDY DESIGN

This is a retrospective cohort study of 437 women with a singleton pregnancy and diagnosis of A2GDM (GDM requiring pharmacotherapy), delivering in a university hospital between 2015 and 2019. Maternal sociodemographic and clinical characteristics, as well as GDM-related factors, including provider type that manages GDM, were compared between women who received insulin versus oral antidiabetic medication (metformin or glyburide) as the first-line pharmacotherapy using univariable and multivariable analyses.

RESULTS

In univariable analysis, maternal age, race and ethnicity, insurance, chronic hypertension, gestational age at GDM diagnosis, glucose level after 50-g glucose loading test, and provider type were associated with insulin prescription. In multivariable analysis, after adjusting for sociodemographic and clinical maternal factors, GDM characteristics and provider type, Hispanic ethnicity (0.26, 95% confidence interval [CI]: 0.09-0.73), and lack of insurance (0.34, 95% CI: 0.13-0.89) remained associated with lower odds of insulin prescription, whereas endocrinology management of GDM (compared with obstetrics and gynecology [OBGYN]) (8.07, 95% CI: 3.27-19.90) remained associated with higher odds of insulin prescription.

CONCLUSION

Women of Hispanic ethnicity and women with no insurance were less likely to receive insulin and more likely to receive oral antidiabetic medication for GDM pharmacotherapy, while management by endocrinology was associated with higher odds of insulin prescription.This finding deserves more investigation to understand if differences are due to patient choice or a health disparity in the choice of pharmacologic agent for A2GDM.

KEY POINTS

· Insulin is recommended as a first-line pharmacotherapy for gestational diabetes.. · Women of Hispanic ethnicity were less likely to receive insulin as first line.. · Lack of insurance was also associated with lower odds of insulin prescription..

Association of Medicaid Expansion in Arkansas With Postpartum Coverage, Outpatient Care, and Racial Disparities

Importance

Non-Hispanic Black individuals are disproportionally covered by Medicaid during pregnancy and, compared with non-Hispanic White individuals, have higher rates of postpartum coverage loss and mortality. Expanded Medicaid coverage under the Affordable Care Act may have increased continuity of coverage and access to care in the critical postpartum period in expansion states.

Objective

To examine the association of Medicaid expansion in Arkansas with continuous postpartum coverage, postpartum health care use, and change in racial disparities in the study outcomes.

Design Setting and Participants

This cohort study with a difference-in-differences analysis compared persons with Medicaid and commercially financed childbirth, stratified by race, using Arkansas' All-Payer Claims Database for persons with a childbirth between 2013 and 2015. Race and ethnicity from birth certificate data were classified as Hispanic, non-Hispanic Black (hereafter Black), non-Hispanic White (hereafter White), and other (including Asian, Native American or Alaska Native, and Pacific Islander) or unknown race. Data were analyzed between June 2020 and August 2021.

Exposures

Medicaid-paid childbirth after January 1, 2014.

Main Outcomes and Measures

Continuous health insurance coverage and the number of outpatient visits during the first 6 months postpartum.

Results

A total of 60 990 childbirths (mean [SD] age of birthing person, 27 [5.3] years; 67% White, 22% Black, and 7% Hispanic) were included, among which 72.3% were paid for by Medicaid and 27.7% were paid for by a commercial payer. Medicaid expansion in Arkansas was associated with a 27.8 (95% CI, 26.1-29.5) percentage point increase in continuous insurance coverage and an increase in outpatient visits of 0.9 (95% CI, 0.7-1.1) during the first 6 months postpartum, representing relative increases of 54.9% and 75.0%, respectively. Racial disparities in postpartum coverage decreased from 6.3 (95% CI, 3.9-8.7) percentage points before expansion to -2.0 (95% CI, -2.8 to -1.2) percentage points after expansion. However, disparities in outpatient care between Black and White individuals persisted after Medicaid expansion (preexpansion difference, 0.4 [95% CI, 0.2-0.6] visits; postexpansion difference, 0.5 [95% CI, 0.4-0.6] visits).

Conclusions and Relevance

In this cohort study with a difference-in-differences analysis of 60 990 childbirths, Medicaid expansion was associated with higher rates of postpartum coverage and outpatient visits and lower racial and ethnic disparities in postpartum coverage. However, disparities in outpatient visits between Black and White individuals were unchanged. Additional policy approaches are needed to reduce racial and ethnic disparities in postpartum care.

Measuring State-Level Racial Inequity in Severe Maternal Morbidity in the Medicaid Population

OBJECTIVE

Severe maternal morbidity represents a "near miss" mortality and is an important measure of quality and safety. Racial inequity in maternal morbidity is stark and the reasons for this disparity are poorly understood. We aimed to identify states achieving racial equity in maternal morbidity in order to identify policies that may promote racial equity.

METHODS

We analyzed Medicaid deliveries from 2008 to 2009 in a sample that included 28 states and the District of Columbia. This dataset included approximately 80% of all Medicaid enrollees and 90% of minority Medicaid enrollees in the US. We determined the Non-Hispanic Black/Non-Hispanic white SMMI rate ratio for each state and categorized the states into groups by rate ratio. We described demographic features of both the general population and study population for these groups of states.

RESULTS

In a sample that included a total of 1,489,134 births, we found that no state/district is achieving equity in severe maternal morbidity. The severe maternal morbidity rate is higher for Non-Hispanic Black than Non-Hispanic white patients in every state included. With a rate ratio ranging from 1.14 to 2.66, there are varying degrees of inequity. States in the group with the most equitable maternal morbidity rates had less inequity across racial subgroups with respect to educational attainment and poverty.

CONCLUSIONS

Identifying geographic areas with varying degrees of inequity may be key to identifying policies to promote equity. Socioecological disparities and inadequate access to care may be factors in racial inequity in maternal morbidity.

Reducing disparities in adverse pregnancy outcomes in the United States

There is growing evidence that rural and racial disparities and social determinants of health (SDOH) impact adverse pregnancy outcomes (APOs) and overall maternal mortality in the United States. These APOs, such as preeclampsia, preterm birth, and intrauterine growth restriction, are in-turn associated with increased risk of future cardiovascular disease (CVD) later in life. Importantly, SDOH such as socioeconomic disadvantages, poor health literacy, transportation barriers, lack of access to adequate health care, food insecurity, and psychosocial stressors have cascading effects on APOs and downstream cardiovascular health. These SDOH are also deeply intertwined with and compounded by existing racial and rural disparities. Pregnancy thus provides a unique opportunity to identify at-risk women from a social determinants perspective, and provide early interventions to optimize long-term CVD and mitigate cardiovascular health disparities. Addressing the challenges posed by these disparities requires a multi-pronged approach and involves national, regional, and individual level solutions. Eliminating disparities will necessitate a nationwide obligation to ensure health care equity via enhanced health insurance coverage, resource investment, and public and clinician accountability.

Call to Action: Maternal Health and Saving Mothers: A Policy Statement From the American Heart Association

The United States has the highest maternal mortality rates among developed countries, and cardiovascular disease is the leading cause. Therefore, the American Heart Association has a unique role in advocating for efforts to improve maternal health and to enhance access to and delivery of care before, during, and after pregnancy. Several initiatives have shaped the time course of major milestones in advancing maternal and reproductive health equity in the United States. There have been significant strides in improving the timeliness of data reporting in maternal mortality surveillance and epidemiological programs in maternal and child health, yet more policy reforms are necessary. To make a sustainable and systemic impact on maternal health, further efforts are necessary at the societal, institutional, stakeholder, and regulatory levels to address the racial and ethnic disparities in maternal health, to effectively reduce inequities in care, and to mitigate maternal morbidity and mortality. In alignment with American Heart Association's mission "to be a relentless force for longer, healthier lives," this policy statement outlines the inequities that influence disparities in maternal outcomes and current policy approaches to improving maternal health and suggests additional potentially impactful actions to improve maternal outcomes and ultimately save mothers' lives.

Protecting and Expanding Medicaid to Improve Women's Health: ACOG Committee Opinion, Number 826

ABSTRACT

Medicaid, the state-federal health insurance program for individuals with low incomes, serves as a safety net for women throughout the life span. Historically, expansions of Medicaid have been associated with improved access to health care, less delay in obtaining health care, better self-reported health, and reductions in mortality. Compared with nonexpansion states, states that have participated in the Affordable Care Act's Medicaid expansion have experienced improvements in maternal and infant mortality and decreases in uninsured rates and have decreased racial inequities for these measures. In addition to supporting policies that expand access to Medicaid, the American College of Obstetricians and Gynecologists strongly supports education for its members, other obstetrician-gynecologists, and other health care practitioners regarding the complex system for regulation of Medicaid and encourages advocacy for policies that increase access to care for all women. This Committee Opinion has been revised to emphasize the importance of Medicaid to improving women's health, the history and growth of Medicaid, including the ACA's Medicaid expansion, and the mechanisms by which changes to the Medicaid program can occur, and it includes relevant examples for each.

Maternal Heart Failure

Heart failure (HF) remains the most common major cardiovascular complication arising in pregnancy and the postpartum period. Mothers who develop HF have been shown to experience an increased risk of death as well as a variety of adverse cardiac and obstetric outcomes. Recent studies have demonstrated that the risk to neonates is significant, with increased risks in perinatal morbidity and mortality, low Apgar scores, and prolonged neonatal intensive care unit stays. Information on the causal factors of HF can be used to predict risk and understand timing of onset, mortality, and morbidity. A variety of modifiable, nonmodifiable, and obstetric risk factors as well as comorbidities are known to increase a patient's likelihood of developing HF, and there are additional elements that are known to portend a poorer prognosis beyond the HF diagnosis. Multidisciplinary cardio‐obstetric teams are becoming more prominent, and their existence will both benefit patients through direct care and increased awareness and educate clinicians and trainees on this patient population. Detection, access to care, insurance barriers to extended postpartum follow‐up, and timely patient counseling are all areas where care for these women can be improved. Further data on maternal and fetal outcomes are necessary, with the formation of State Maternal Perinatal Quality Collaboratives paving the way for such advances.

Universal Health Care for the United States: A Primer for Health Care Providers

The United States is one of a very few high-income countries that does not guarantee every person the right to health care. Residents of the United States pay more out-of-pocket for increasingly worse outcomes. People of color, those who have lower incomes, and those who live in rural areas have less access to health care and are therefore at even greater risk for poor health. Universal health care, a term for various models of health care systems that provide care for every resident of a given country, will help move the United States toward higher quality, more affordable, and more equitable care. This article defines a reproductive justice and human rights foundation for universal health care, explores how health insurance has worked historically in the United States, identifies the economic reasons for implementing universal health care, and discusses international models that could be used domestically.

Factors Associated With Postpartum Uninsurance Among Medicaid-Paid Births

Importance

To reduce postpartum uninsurance and improve postpartum health, the American Rescue Plan included an option for states to extend pregnancy-related Medicaid from 60 days to 1 year after childbirth. Recent estimates of postpartum uninsurance among Medicaid-paid births would provide information on who would benefit from state adoption of this extension.

Objective

To estimate rates of postpartum uninsurance among individuals with Medicaid-paid births.

Design Setting and Participants

This cross-sectional study used survey data from the 2015 to 2018 Pregnancy Risk Assessment Monitoring System (PRAMS), a representative sample of births in 43 states and New York City, New York, and included PRAMS participants for whom Medicaid was the primary payer for childbirth. The mean weighted PRAMS response rate was 60.9% for the sites and years included in this study. The data were analyzed from December 2020 to January 2021.

Interventions or Exposures

Self-reported postpartum uninsurance measured at the time of the PRAMS survey (mean [interquartile range], 4.2 (3.0-5.0) months after birth).

Main Outcomes and Measures

Survey-weighted rates of postpartum uninsurance and 95% CIs overall, by state, by state Medicaid expansion status, and by maternal sociodemographic characteristics. Adjusted odds ratios of the association between maternal characteristics and postpartum uninsurance.

Results

We identified 63 370 respondents with a Medicaid-paid birth. Of these, 22 016 (41.1%) were non-Hispanic White individuals, 17 442 (22.0%) non-Hispanic Black individuals, 6808 (13.3%) Spanish-speaking Hispanic individuals, 7000 (13.7%) English-speaking Hispanic individuals, 2410 (4.0%) Asian/Pacific Islander individuals, and 3894 (1.3%) Indigenous individuals. Of these, 41.7% were no longer insured by Medicaid postpartum and 22.0% were uninsured postpartum. The postpartum uninsurance rate was 3 times higher in Medicaid nonexpansion states (36.8%) compared with expansion states (12.8%). Postpartum uninsurance varied significantly across states, ranging from 1.7% in Massachusetts to 56.7% in Texas. There were substantial racial and ethnic disparities in postpartum uninsurance: 54.9% of Hispanic, Spanish-speaking individuals (adjusted odds ratio [aOR], 6.2; 95% CI, 5.5-7.0) and 42.8% of Indigenous respondents reported postpartum uninsurance (aOR, 4.3; 95% CI, 3.8-4.9) compared with 15.2% of non-Hispanic White respondents. The odds of postpartum uninsurance was higher among unmarried people (aOR, 1.3 compared with married people; 95% CI, 1.2-1.4), those 35 years and older (aOR, 1.5 compared with those younger than 20 years; 95% CI, 1.2-1.9) and those with lower levels of education (aOR, 0.8 for more than high school compared with less than high school; 95% CI, 0.7-0.9).

Conclusions and Relevance

In this cross-sectional survey study of 43 states, a high proportion of people with Medicaid-paid births were uninsured in the postpartum period, particularly those living in Medicaid nonexpansion states. The study findings suggest that state extensions of pregnancy-related Medicaid eligibility through the first year postpartum could disproportionately benefit Hispanic and Indigenous people, unmarried people, those with lower education levels, and those living in Medicaid nonexpansion states.

Reproductive-Age Women's Experience of Accessing Treatment for Opioid Use Disorder: "We Don't Do That Here"

PURPOSE

For reproductive-age women, medications for opioid use disorder (OUD) decrease risk of overdose death and improve outcomes but are underutilized. Our objective was to provide a qualitative description of reproductive-age women's experiences of seeking an appointment for medications for OUD.

METHODS

Trained female callers placed telephone calls to a representative sample of publicly listed opioid treatment clinics and buprenorphine providers in Florida, Kentucky, Massachusetts, Michigan, Missouri, North Carolina, Tennessee, Virginia, Washington, and West Virginia to obtain appointments to receive medication for OUD. Callers were randomly assigned to be pregnant or non-pregnant and have private or Medicaid-based insurance to assess differences in the experiences of access by these characteristics. The callers placed 28,651 uniquely randomized calls, 10,117 to buprenorphine-waivered prescribers and 754 to opioid treatment programs. Open-ended, qualitative data were obtained from the callers about the access experiences and were analyzed using a qualitative, iterative inductive-deductive approach. From all 28,651 total calls, there were 17,970 unique free-text comments to the question "Please give an objective play-by-play of the description of what happened in this conversation."

FINDINGS

Analysis demonstrated a common path to obtaining an appointment. Callers frequently experienced long hold times, multiple transfers, and difficult interactions. Clinic receptionists were often mentioned as facilitating or obstructing access. Pregnant callers and those with Medicaid noted more barriers. Obtaining an appointment was commonly difficult even for these persistent, trained callers.

CONCLUSIONS

Interventions are needed to improve the experiences of reproductive-age women as they enter care for OUD, especially for pregnant women and those with Medicaid coverage.

Medicaid Expansion Improved Perinatal Insurance Continuity For Low-Income Women

Insurance churn, or moving between different insurance plans or between insurance and uninsurance, is common during the perinatal period. We used survey data from the 2012-17 Pregnancy Risk Assessment Monitoring System to estimate the impact of Affordable Care Act-related state Medicaid expansions on continuity of insurance coverage for low-income women across three time points: preconception, delivery, and postpartum. We found that Medicaid expansion resulted in a 10.1-percentage-point decrease in churning between insurance and uninsurance, representing a 28 percent decrease from the prepolicy baseline in expansion states. This decrease was driven by a 5.8-percentage-point increase in the proportion of women who were continuously insured and a 4.2-percentage-point increase in churning between Medicaid and private insurance. Medicaid expansion improved insurance continuity in the perinatal period for low-income women, which may improve the quality of perinatal health care, but it also increased churning between public and private health insurance.

Race, Medicaid Coverage, and Equity in Maternal Morbidity

BACKGROUND

Severe maternal morbidity (SMM) affects 50,000 deliveries in the United States annually, with around 1.5 times the rates among Medicaid-covered relative to privately covered deliveries. Furthermore, large racial inequities exist in SMM for non-Hispanic Black women and Hispanic women with rates being 2.1 and 1.4 times higher than White women, respectively. This study aimed to compare the differences in SMM among women of different races/ethnicities and delivery insurance types. Quantifying the rates of SMM based on the intersection of race/ethnicity and insurance status can help to elucidate how multiple forms of oppression and racism may contribute to the substantial inequities in SMM among Black women.

METHODS

Using hospital discharge data from the Healthcare Cost and Utilization Project National Inpatient Sample (years 2016 and 2017), we conducted multivariate logistic models to evaluate equity in maternal outcomes among women with different primary payers, overall and stratified by race/ethnicity.

RESULTS

We found a rate of SMM equal to 138.3 per 10,000 deliveries. Differences in the rate of SMM among non-Hispanic Black, non-Hispanic Asian, and Hispanic women relative to White women were lower among Medicaid-covered deliveries relative to deliveries of all payer types. For example, among all payers, Black women had 2.17 (221.3 vs. 102.1 per 10,000) times the rate of SMM compared with White women; however, among Medicaid-covered deliveries, Black women had 1.84 (227.3 vs. 123.2) times the rate. Despite increased risk associated with Medicaid coverage (adjusted odds ratio, 1.12; 95% confidence interval, 1.07-1.16), the risk was no longer significant in the stratified regression including Black women (adjusted odds ratio, 1.06; 95% confidence interval, 0.98-1.15).

CONCLUSIONS

Our findings suggest that Black women with Medicaid do not have higher rates of SMM relative to Black women with private insurance. National and state policy efforts should continue to focus on addressing structural racism and other socioeconomic drivers of adverse maternal outcomes, including barriers to high-quality care among women with Medicaid coverage.

The 2014 New York State Medicaid Expansion and Severe Maternal Morbidity During Delivery Hospitalizations

BACKGROUND

Medicaid expansions under the Affordable Care Act have increased insurance coverage and prenatal care utilization in low-income women. However, it is not clear whether they are associated with any measurable improvement in maternal health outcomes. In this study, we compared the changes in the incidence of severe maternal morbidity (SMM) during delivery hospitalizations between low- and high-income women associated with the 2014 Medicaid expansion in New York State.

METHODS

Data for this retrospective cohort study came from the 2006-2016 New York State Inpatient Database, a census of discharge records from community hospitals. The outcome was SMM during delivery hospitalizations, as defined by the Centers for Disease Control and Prevention. We used regression coefficients (β) from multivariable logistic models: (1) to compare independently in low-income women and in high-income women the changes in slopes in the incidence of SMM before (2006-2013) and after (2014-2016) the expansion, and (2) to compare low- and high-income women for the changes in slopes in the incidence of SMM before and after the expansion.

RESULTS

A total of 2,286,975 delivery hospitalizations were analyzed. The proportion of Medicaid beneficiaries in parturients increased a relative 12.1% (95% confidence interval [CI], 11.8-12.4), from 42.9% in the preexpansion period to 48.1% in the postexpansion period, whereas the proportion of the uninsured decreased a relative 4.8% (95% CI, 2.8-6.8). Multivariable logistic modeling revealed that implementation of the 2014 Medicaid expansion was associated with a decreased slope during the postexpansion period both in low-income women (β = -0.0161 or 1.6% decrease; 95% CI, -0.0190 to -0.0132) and in high-income women (β = -0.0111 or 1.1% decrease; 95% CI, -0.0130 to -0.0091). The decrease in slope during the postexpansion period was greater in low- than in high-income women (β = -0.0042 or 0.42% difference; 95% CI, -0.0076 to -0.0007).

CONCLUSIONS

Implementation of the Medicaid expansion in 2014 in New York State is associated with a small but statistically significant reduction in the incidence of SMM in low-income women compared with high-income women.

Medicaid Expansion Increased Preconception Health Counseling, Folic Acid Intake, And Postpartum Contraception

The period before pregnancy is critically important for the health of a woman and her infant, yet not all women have access to health insurance during this time. We evaluated whether increased access to health insurance under the Affordable Care Act Medicaid expansions affected ten preconception health indicators, including the prevalence of chronic conditions and health behaviors, birth control use and pregnancy intention, and receipt of preconception health services. By comparing changes in outcomes for low-income women in expansion and nonexpansion states, we document greater preconception health counseling, prepregnancy folic acid intake, and postpartum use of effective birth control methods among low-income women associated with Medicaid expansion. We do not find evidence of changes on the other preconception health indicators examined. Our findings indicate that expanding Medicaid led to detectable improvements on a subset of preconception health measures.
