Racial And Ethnic Inequities In Postpartum Depressive Symptoms, Diagnosis, And Care In 7 US Jurisdictions.

Understanding whether racial and ethnic inequities exist along the postpartum mental health care continuum is vital because inequitable identification of depression can lead to inequitable referral to and receipt of care. We aimed to expand on existing cross-sectional and single-state data documenting potential racial and ethnic disparities in postpartum depression care. Using early (from two to six months) and late (from twelve to fourteen months) postpartum survey data from seven US jurisdictions, we documented patterns of early postpartum depressive symptoms, perinatal mood and anxiety disorder (PMAD) diagnosis, and receipt of postpartum mental health care overall and by racial and ethnic identity. Of 4,542 people who delivered live births in 2020, 11.8 percent reported early postpartum depressive symptoms. Among the sample with these symptoms, only 25.4 percent reported receiving a PMAD diagnosis, and 52.8 percent reported receiving some form of postpartum mental health care. There were no significant differences in diagnosis by race and ethnicity. Respondents identifying as Asian; Native Hawaiian or Pacific Islander; Southwest Asian, Middle Eastern, or North African; Hispanic; and non-Hispanic Black were significantly less likely than non-Hispanic White respondents to receive mental health care, demonstrating stark inequities in the management of postpartum depressive symptoms. Policies mandating and reimbursing universal postpartum depression screening, facilitating connection to care, reducing insurance coverage gaps, and enhancing clinician training in culturally responsive care may promote equitable postpartum mental health care.

Disparities in Mistreatment During Childbirth.

Importance: Lack of respectful maternity care may be a key factor associated with disparities in maternal health. However, mistreatment during childbirth has not been widely documented in the US. Objectives: To estimate the prevalence of mistreatment by health care professionals during childbirth among a representative multistate sample and to identify patient characteristics associated with mistreatment experiences. Design, Setting, and Participants: This cross-sectional study used representative survey data collected from respondents to the 2020 Pregnancy Risk and Monitoring System in 6 states and New York City who had a live birth in 2020 and participated in the Postpartum Assessment of Health Survey at 12 to 14 months' post partum. Data were collected from January 1, 2021, to March 31, 2022. Exposures: Demographic, social, clinical, and birth characteristics that have been associated with patients' health care experiences. Main Outcomes and Measures: Any mistreatment during childbirth, as measured by the Mistreatment by Care Providers in Childbirth scale, a validated measure of self-reported experiences of 8 types of mistreatment. Survey-weighted rates of any mistreatment and each mistreatment indicator were estimated, and survey-weighted logistic regression models estimated odds ratios (ORs) and 95% CIs. Results: The sample included 4458 postpartum individuals representative of 552 045 people who had live births in 2020 in 7 jurisdictions. The mean (SD) age was 29.9 (5.7) years, 2556 (54.4%) identified as White, and 2836 (58.8%) were commercially insured. More than 1 in 8 individuals (13.4% [95% CI, 11.8%-15.1%]) reported experiencing mistreatment during childbirth. The most common type of mistreatment was being "ignored, refused request for help, or failed to respond in a timely manner" (7.6%; 95% CI, 6.5%-8.9%). Factors associated with experiencing mistreatment included being lesbian, gay, bisexual, transgender, queer identifying (unadjusted OR [UOR], 2.3; 95% CI, 1.4-3.8), Medicaid insured (UOR, 1.4; 95% CI, 1.1-1.8), unmarried (UOR, 0.8; 95% CI, 0.6-1.0), or obese before pregnancy (UOR, 1.3; 95% CI, 1.0-1.7); having an unplanned cesarean birth (UOR, 1.6; 95% CI, 1.2-2.2), a history of substance use disorder (UOR, 2.6; 95% CI, 1.3-5.1), experienced intimate partner or family violence (UOR, 2.3; 95% CI, 1.3-4.2), mood disorder (UOR, 1.5; 95% CI, 1.1-2.2), or giving birth during the COVID-19 public health emergency (UOR, 1.5; 95% CI, 1.1-2.0). Associations of mistreatment with race and ethnicity, age, educational level, rural or urban geography, immigration status, and household income were ambiguous. Conclusions and Relevance: This cross-sectional study of individuals who had a live birth in 2020 in 6 states and New York City found that mistreatment during childbirth was common. There is a need for patient-centered, multifaceted interventions to address structural health system factors associated with negative childbirth experiences.

Continuous Medicaid Eligibility During the COVID-19 Pandemic and Postpartum Coverage, Health Care, and Outcomes.

Importance: Pursuant to the Families First Coronavirus Response Act (FFCRA), continuous Medicaid eligibility during the COVID-19 public health emergency (PHE) created a de facto national extension of pregnancy Medicaid eligibility beyond 60 days postpartum. Objective: To evaluate the association of continuous Medicaid eligibility with postpartum health insurance, health care use, breastfeeding, and depressive symptoms. Design, Setting, and Participants: This cohort study using a generalized difference-in-differences design included 21 states with continuous prepolicy (2017-2019) and postpolicy (2020-2021) participation in the Pregnancy Risk Assessment Monitoring System (PRAMS). Exposures: State-level change in Medicaid income eligibility after 60 days postpartum associated with the FFCRA measured as a percent of the federal poverty level (FPL; ie, the difference in 2020 income eligibility thresholds for pregnant people and low-income adults/parents). Main Outcomes and Measures: Health insurance, postpartum visit attendance, contraceptive use (any effective method; long-acting reversible contraceptives), any breastfeeding and depressive symptoms at the time of the PRAMS survey (mean [SD], 4 [1.3] months postpartum). Results: The sample included 47 716 PRAMS respondents (64.4% aged <30 years; 18.9% Hispanic, 26.2% non-Hispanic Black, 36.3% non-Hispanic White, and 18.6% other race or ethnicity) with a Medicaid-paid birth. Based on adjusted estimates, a 100% FPL increase in postpartum Medicaid eligibility was associated with a 5.1 percentage point (pp) increase in reported postpartum Medicaid enrollment, no change in commercial coverage, and a 6.6 pp decline in uninsurance. This represents a 40% reduction in postpartum uninsurance after a Medicaid-paid birth compared with the prepolicy baseline of 16.7%. In subgroup analyses by race and ethnicity, uninsurance reductions were observed only among White and Black non-Hispanic individuals; Hispanic individuals had no change. No policy-associated changes were observed in other outcomes. Conclusions and Relevance: In this cohort study, continuous Medicaid eligibility during the COVID-19 PHE was associated with significantly reduced postpartum uninsurance for people with Medicaid-paid births, but was not associated with postpartum visit attendance, contraception use, breastfeeding, or depressive symptoms at approximately 4 months postpartum. These findings, though limited to the context of the COVID-19 PHE, may offer preliminary insight regarding the potential impact of post-pandemic postpartum Medicaid eligibility extensions. Collection of longer-term and more comprehensive follow-up data on postpartum health care and health will be critical to evaluating the effect of ongoing postpartum policy interventions.

Comparing approaches to identify live births using the Transformed Medicaid Statistical Information System.

OBJECTIVE: To evaluate the performance of different approaches for identifying live births using Transformed Medicaid Statistical Information System Analytic Files (TAF). DATA SOURCES: The primary data source for this study were TAF inpatient (IP), other services (OT), and demographic and eligibility files. These data contain administrative claims for Medicaid enrollees in all 50 states and the District of Columbia from January 1, 2018 to December 31, 2018. STUDY DESIGN: We compared five approaches for identifying live birth counts obtained from the TAF IP and OT data with the Centers for Disease Control and Prevention (CDC) Natality data-the gold standard for birth counts at the state level. DATA COLLECTION/EXTRACTION METHODS: The five approaches used varying combinations of diagnosis and procedure, revenue, and place of service codes to identify live births. Approaches 1 and 2 follow guidance developed by the Centers for Medicare and Medicaid Services (CMS). Approaches 3 and 4 build on the approaches developed by CMS by including all inpatient hospital claims in the OT file and excluding codes related to delivery services for infants, respectively. Approach 5 applied Approach 4 to only the IP file. PRINCIPAL FINDINGS: Approach 4, which included all inpatient hospital claims in the OT file and excluded codes related to infants to identify deliveries, achieved the best match of birth counts relative to CDC birth record data, identifying 1,656,794 live births-a national overcount of 3.6%. Approaches 1 and 3 resulted in larger overcounts of births (20.5% and 4.5%), while Approaches 2 and 5 resulted in undercounts of births (-3.4% and -6.8%). CONCLUSIONS: Including claims from both the IP and OT files, and excluding codes unrelated to the delivery episode and those specific to services rendered to infants improves accuracy of live birth identification in the TAF data.

Differences in Self-Reported and Billed Postpartum Visits Among Medicaid-Insured Individuals.

Importance: State Medicaid programs have recently implemented several policies to improve access to health care during the postpartum period. Understanding whether these policies are succeeding will require accurate measurement of postpartum visit use over time and across states; however, current estimates of use vary substantially between data sources. Objectives: To examine disagreement between postpartum visit use reported in the Pregnancy Risk Assessment Monitoring System (PRAMS) and Medicaid claims and assess whether insurance transitions from Medicaid at the time of childbirth to other insurance types after delivery are associated with the degree of disagreement. Design, Setting, and Participants: This cross-sectional study was conducted among individuals in South Carolina after delivery who had completed a PRAMS survey and for whom Medicaid was the payer of their delivery care. PRAMS responses from 2017 to 2020 were linked to inpatient, outpatient, and physician Medicaid claims; survey-weighted logistic regression models were then used to examine the association between postpartum insurance transitions and data source disagreement. Data were analyzed from February through October 2023. Exposure: Insurance transition type: continuous Medicaid, Medicaid to private insurance, Medicaid to no insurance, and Emergency Medicaid to no insurance. Main Outcome and Measure: Data source disagreement due to reporting a postpartum visit in PRAMS without a Medicaid claim for a visit or having a Medicaid claim for a visit without reporting a postpartum visit in PRAMS. Results: Among 836 PRAMS respondents enrolled in Medicaid at delivery (663 aged 20-34 years [82.9%]), a mean of 85.7% (95% CI, 82.1%-88.7%) reported a postpartum visit in PRAMS and a mean of 61.6% (95% CI, 56.9%-66.0%) had a Medicaid claim for a postpartum visit. Overall, 253 respondents (30.3%; 95% CI, 26.1%-34.7%) had data source disagreement: 230 individuals (27.2%; 95% CI, 23.2%-31.5%) had a visit in PRAMS without a Medicaid claim, and 23 individuals (3.1%; 95% CI, 1.8%-5.2%) had a Medicaid claim without a visit in PRAMS. Compared with individuals continuously enrolled in Medicaid, those who transitioned to private insurance after delivery and those who were uninsured after delivery and had Emergency Medicaid at delivery had an increase in the probability of data source agreement of 15.8 percentage points (95% CI, 2.6-29.1 percentage points) and 37.2 percentage points (95% CI, 19.6-54.8 percentage points), respectively. Conclusions and Relevance: This study's findings suggest that Medicaid claims may undercount postpartum visits among people who lose Medicaid or switch to private insurance after childbirth. Accounting for these insurance transitions may be associated with better claims-based estimates of postpartum care.

Consistency and Adequacy of Public and Commercial Health Insurance for US Children, 2016 to 2021.

Importance: Before and during the COVID-19 public health emergency (PHE), commercially and publicly insured children may have faced different challenges in obtaining consistent and adequate health insurance. Objective: To compare overall rates, COVID-19 PHE-related changes, and child and family characteristics associated with inconsistent and inadequate coverage for publicly and commercially insured children. Design, Settings, and Participants: This was a cross-sectional study using nationally representative data from the 2016 to 2021 National Survey of Children's Health of children from age 0 to 17 years living in noninstitutional settings. Exposure: Parent- or caregiver-reported current child health insurance type defined as public or commercial. Main Outcomes and Measures: Inconsistent insurance, defined as having an insurance gap in the past year; and inadequate insurance, defined by failure to meet 3 criteria: (1) benefits usually/always sufficient to meet child's needs; (2) coverage usually/always allows child to access needed health care practitioners; and (3) no or usually/always reasonable annual out-of-pocket payments for child's health care. Survey-weighted logistic regression was used to compare outcomes by insurance type, by year (2020-2021 vs 2016-2019), and by child characteristics within insurance type. Results: Of this nationally representative sample of 203 691 insured children, 34.5% were publicly insured (mean [SD] age, 8.4 [4.1] years; 47.4% female) and 65.5% were commercially insured (mean [SD] age, 8.7 [5.6]; 49.1% female). Most publicly insured children were either non-Hispanic Black (20.9%) or Hispanic (36.4%); living with 2 married parents (38.4%) or a single parent (33.1%); and had a household income less than 200% of the federal poverty level (79%). Most commercially insured children were non-Hispanic White (62.8%), living with 2 married parents (79.0%); and had a household income of 400% of the federal poverty level or higher (49.1%). Compared with commercially insured children, publicly insured children had higher rates of inconsistent coverage (4.2% vs 1.4%; difference, 2.7 percentage points [pp]; 95% CI, 2.3 to 3.2) and lower rates of inadequate coverage (12.2% vs 33.0%; difference, -20.8 pp; 95% CI, -21.6 to -20.0). Compared with the period from 2016 to 2019, inconsistent insurance decreased by 42% for publicly insured children and inadequate insurance decreased by 6% for commercially insured children during the COVID-19 PHE (2020-2021). The child and family characteristics associated with inadequate and inconsistent insurance varied by insurance type. Conclusions and Relevance: The findings of this cross-sectional study indicate that insurance gaps are a particular problem for publicly insured children, whereas insurance inadequacy and particularly, out-of-pocket costs are a challenge for commercially insured children. Both challenges improved during the COVID-19 PHE. Improving children's health coverage after the PHE will require policy solutions that target the unique needs of commercially and publicly insured children.

The Health And Social Needs Of Medicaid Beneficiaries In The Postpartum Year: Evidence From A Multistate Survey.

As of September 2023, thirty-seven states and Washington, D.C., had adopted the option in the American Rescue Plan Act of 2021 to extend pregnancy Medicaid eligibility to one year postpartum. To inform state initiatives to support this newly covered population, we conducted a representative survey of postpartum people in six states and New York City from January 2021 to March 2022. Compared with respondents who had commercial insurance at the time of childbirth, Medicaid respondents were less likely to have a usual source of care and reported less use of primary, specialty, and dental care in the postpartum year. Depression symptoms and social concerns such as food insecurity, intimate partner violence, and financial strain were significantly higher in the Medicaid population. Rates of anxiety symptoms, delaying or not getting needed care, and unsatisfactory child care were similar in both populations. Our findings suggest that postpartum Medicaid extensions should be coupled with state initiatives to address beneficiaries' health and social needs. National investments in data collection on postpartum people will be critical to support evidence-based policy making to improve maternal health and well-being.

Late Postpartum Coverage Loss Before COVID-19: Implications For Medicaid Unwinding.

Using unique Pregnancy Risk Assessment Monitoring System follow-up data from before the COVID-19 pandemic, we found that only 68 percent of prenatal Medicaid enrollees maintained continuous Medicaid coverage through nine or ten months postpartum. Of the prenatal Medicaid enrollees who lost coverage in the early postpartum period, two-thirds remained uninsured nine to ten months postpartum. State postpartum Medicaid extensions could prevent a return to prepandemic rates of postpartum coverage loss.

Medicaid expansion and risk of eclampsia.

BACKGROUND: Eclampsia is an indicator of severe maternal morbidity and can be prevented through increased prenatal care access and early prenatal care utilization. The 2014 Medicaid expansion under the Patient Protection and Affordable Care Act allowed states to expand Medicaid coverage to nonelderly adults with incomes up to 138% of the federal poverty level. Its implementation has led to a significant increase in prenatal care access and utilization. OBJECTIVE: This study aimed to assess the association of Medicaid expansion under the Affordable Care Act with eclampsia incidence. STUDY DESIGN: This natural experiment study was based on US birth certificate data from January 2010 to December 2018 in 16 states that expanded Medicaid in January 2014 and in 13 states that did not expand Medicaid during the study period. The outcome was eclampsia incidence, the intervention was the implementation of the Medicaid expansion, and the exposure was state expansion status. Using the interrupted time series method, we compared temporal trends in the incidence of eclampsia before and after the intervention in expansion vs non-expansion states with adjustments for patient and hospital county characteristics. RESULTS: Of the 21,570,021 birth certificates analyzed, 11,433,862 (53.0%) were in expansion states and 12,035,159 (55.8%) were in the postintervention period. The diagnosis of eclampsia was recorded in 42,677 birth certificates or 19.8 per 10,000 (95% confidence interval, 19.6-20.0). The incidence of eclampsia was higher for Black people (29.1 per 10,000) than for White (20.7 per 10,000), Hispanic (15.3 per 10,000), and birthing people of other race and ethnicity (15.4 per 10,000). In the expansion states, the incidence of eclampsia increased during the preintervention period and decreased during the postintervention period; in the nonexpansion states, a reverse pattern was observed. A statistically significant difference was observed between expansion and nonexpansion states in temporal trends between the pre- and postintervention periods, with an overall 1.6% decrease (95% confidence interval, 1.3-1.9) in the incidence of eclampsia in expansion states compared with nonexpansion states. The results were consistent in subgroup analyses according to maternal race and ethnicity, education level (less than high school or high school and higher), parity (nulliparous or parous), delivery mode (vaginal or cesarean delivery), and poverty in the residence county (high or low). CONCLUSION: Implementation of the Affordable Care Act Medicaid expansion was associated with a small statistically significant reduction in the incidence of eclampsia. Its clinical significance and cost-effectiveness remain to be determined.

Variation in Outpatient Postpartum Care Use in the United States: A Latent Class Analysis.

INTRODUCTION: Despite efforts to improve postpartum health care in the United States, little is known about patterns of postpartum care beyond routine postpartum visit attendance. This study aimed to describe variation in outpatient postpartum care patterns. METHODS: In this longitudinal cohort study of national commercial claims data, we used latent class analysis to identify subgroups of patients (classes) with similar outpatient postpartum care patterns (defined by the number of preventive, problem, and emergency department outpatient visits in the 60 days after birth). We also compared classes in terms of maternal sociodemographics and clinical characteristics measured at childbirth, as well as total health spending and rates of adverse events (all-cause hospitalizations and severe maternal morbidity) measured from childbirth to the late postpartum period (61-365 days after birth). RESULTS: The study cohort included 250,048 patients hospitalized for childbirth in 2016. We identified six classes with distinct outpatient postpartum care patterns in the 60 days after birth, which we classified into three broad groups: no care (class 1 [32.4% of the total sample]); preventive care only (class 2 [18.3%]); and problem care (classes 3-6 [49.3%]). The prevalence of clinical risk factors at childbirth increased progressively from class 1 to class 6; for example, 6.7% of class 1 patients had any chronic disease compared with 15.5% of class 5 patients. Severe maternal morbidity was highest among the high problem care classes (classes 5 and 6): 1.5% of class 6 patients experienced severe maternal morbidity in the postpartum period and 0.5% in the late postpartum period, compared with less than 0.1% of patients in classes 1 and 2. CONCLUSIONS: Efforts to redesign and measure postpartum care should reflect the current heterogeneity in care patterns and clinical risks in the postpartum population.

Using Modernized Medicaid Data to Advance Evidence-Based Improvements in Maternal Health.

Medicaid is the primary payor for nearly half of all births in the United States and plays a disproportionate role in covering maternity care for low-income people, rural people, and minoritized racial groups. Newly available, modernized Medicaid claims data-the Transformed Medicaid Statistical Information System Analytic Files (TAF)-offer a significant opportunity to conduct novel research that can drive the development of evidence-based programs and policies for Medicaid beneficiaries before, during, and after pregnancy. Yet, the public health research community has so far underused the TAF for maternal health research. We provide an overview of the TAF and how they compare to other major data sets available to study maternal health. We highlight some major limitations of the TAF and offer strategies to maximize the potential of these novel data to accelerate timely, rigorous research to improve maternal health and health equity.

Association of the United States Affordable Care Act Dependent Coverage Provision with Labor Neuraxial Analgesia Use.

BACKGROUND: Providing continuous health insurance coverage during the perinatal period may increase access to and utilization of labor neuraxial analgesia. This study tested the hypothesis that implementation of the 2010 Dependent Coverage Provision of the Patient Protection and Affordable Care Act, requiring private health insurers to allow young adults to remain on their parent's plan until age 26 yr, was associated with increased labor neuraxial analgesia use. METHODS: This study used a natural experiment design and birth certificate data for spontaneous vaginal deliveries in 28 U.S. states between 2009 and 2013. The intervention was the Dependent Coverage Provision, categorized into pre- and postintervention periods (January 2009 to August 2010 and September 2010 to December 2013, respectively). The exposure was women's age, categorized as exposed (21 to 25 yr) and unexposed (27 to 31 yr). The outcome was the labor neuraxial analgesia utilization rate. RESULTS: Of the 4,515,667 birth certificates analyzed, 3,033,129 (67.2%) indicated labor neuraxial analgesia use. For women aged 21 to 25 yr, labor neuraxial analgesia utilization rates were 64.9% during the preintervention period and 68.9% during the postintervention period (difference, 4.0%; 95% CI, 3.9 to 4.2). For women aged 27 to 31 yr, labor neuraxial analgesia utilization rates were 64.9% during the preintervention period and 67.7% during the postintervention period (difference, 2.8%; 95% CI, 2.7 to 2.9). After adjustment, implementation of the Dependent Coverage Provision was associated with a 1.0% (95% CI, 0.8 to 1.2) absolute increase in labor neuraxial analgesia utilization rate among women aged 21 to 25 yr compared with women aged 27 to 31 yr. The increase was statistically significant for White and Hispanic women but not for Black and Other race and ethnicity women. CONCLUSIONS: Implementation of the Dependent Coverage Provision was associated with a statistically significant increase in labor neuraxial analgesia use, but the small effect size is unlikely of clinical significance.

State Variation in Severe Maternal Morbidity Among Individuals With Medicaid Insurance.

OBJECTIVE: To measure variation in delivery-related severe maternal morbidity (SMM) among individuals with Medicaid insurance by state and by race and ethnicity across and within states. METHODS: We conducted a pooled, cross-sectional analysis of the 2016-2018 TAF (Transformed Medicaid Statistical Information System Analytic Files). We measured overall and state-level rates of SMM without blood transfusion for all individuals with Medicaid insurance with live births in 49 states and Washington, DC. We also examined SMM rates among non-Hispanic Black and non-Hispanic White individuals with Medicaid insurance in a subgroup of 27 states (and Washington, DC). We generated unadjusted rates of composite SMM and the individual indicators of SMM that comprised the composite. Rate differences and rate ratios were calculated to compare SMM rates for non-Hispanic Black and non-Hispanic White individuals with Medicaid insurance. RESULTS: The overall rate of SMM without blood transfusion was 146.2 (95% CI 145.1-147.3) per 10,000 deliveries (N=4,807,143). Rates of SMM ranged nearly threefold, from 80.3 (95% CI 71.4-89.2) per 10,000 deliveries in Utah to 210.4 (95% CI 184.6-236.1) per 10,000 deliveries in Washington, DC. Non-Hispanic Black individuals with Medicaid insurance (n=629,774) experienced a higher overall rate of SMM (212.3, 95% CI 208.7-215.9) compared with non-Hispanic White individuals with Medicaid insurance (n=1,051,459); (125.3, 95% CI 123.2-127.4) per 10,000 deliveries (rate difference 87.0 [95% CI 82.8-91.2]/10,000 deliveries; rate ratio 1.7 [95% CI 1.7-1.7]). The leading individual indicator of SMM among all individuals with Medicaid insurance was eclampsia, although the leading indicators varied across states and by race and ethnicity. Many states were concordant in leading indicators among the overall, non-Hispanic Black, and non-Hispanic White populations (ie, in Oklahoma sepsis was the leading indicator for all three). Most states, however, were discordant in leading indicators across the three groups (ie, in Texas eclampsia was the leading indicator overall, pulmonary edema or acute heart failure was the leading indicator among the non-Hispanic Black population, and sepsis was the leading indicator among the non-Hispanic White population). CONCLUSION: Interventions aimed at reducing SMM and, ultimately, mortality among individuals with Medicaid insurance may benefit from the data generated from this study, which highlights states that have the greatest burden of SMM, the differences in rates among non-Hispanic Black populations compared with non-Hispanic White populations, and the leading indicators of SMM overall, by state, and by race and ethnicity.

Rural and Urban Differences in Insurance Coverage at Prepregnancy, Birth, and Postpartum.

OBJECTIVE: To measure insurance coverage at prepregnancy, birth, and postpartum, and insurance coverage continuity across these periods among rural and urban U.S. residents. METHODS: We performed a pooled, cross-sectional analysis of survey data from 154,992 postpartum individuals in 43 states and two jurisdictions that participated in the 2016-2019 PRAMS (Pregnancy Risk Assessment Monitoring System). We calculated unadjusted estimates of insurance coverage (Medicaid, commercial, or uninsured) during three periods (prepregnancy, birth, and postpartum), as well as insurance continuity across these periods among rural and urban U.S. residents. We conducted subgroup analyses to compare uninsurance rates among rural and urban residents by sociodemographic and clinical characteristics. We used logistic regression models to generate adjusted odds ratios (aORs) for each comparison. RESULTS: Rural residents experienced greater odds of uninsurance in each period and continuous uninsurance across all three periods, compared with their urban counterparts. Uninsurance was higher among rural residents compared with urban residents during prepregnancy (15.4% vs 12.1%; aOR 1.19, 95% CI 1.11-1.28], at birth (4.6% vs 2.8%; aOR 1.60, 95% CI 1.41-1.82), and postpartum (12.7% vs 9.8%, aOR 1.27, 95% CI 1.17-1.38]. In each period, rural residents who were non-Hispanic White, married, and with intended pregnancies experienced greater adjusted odds of uninsurance compared with their urban counterparts. Rural-urban differences in uninsurance persisted across both Medicaid expansion and non-expansion states, and among those with varying levels of education and income. Rural inequities in perinatal coverage were experienced by Hispanic, English-speaking, and Indigenous individuals during prepregnancy and at birth. CONCLUSION: Perinatal uninsurance disproportionately affects rural residents, compared with urban residents, in the 43 states examined. Differential insurance coverage may have important implications for addressing rural-urban inequities in maternity care access and maternal health.

Perinatal Care Changes During COVID-19: A Population-Based Analysis by Race/Ethnicity.

INTRODUCTION: The COVID-19 public health emergency created unprecedented disruptions in the use of healthcare services, which could have affected long-standing racial‒ethnic disparities in maternal care use and outcomes. This study evaluates population-level changes in perinatal health services associated with the COVID-19 pandemic overall and by maternal race‒ethnicity. METHODS: In this analysis of all U.S. live births from 2016 to 2020, interrupted time-series analysis was used to estimate the change in the mean number of prenatal care visits and rates of hospital birth, labor induction, and cesarean delivery associated with the start of the pandemic (March 2020) overall and by maternal race‒ethnicity. Analyses were conducted in 2022. RESULTS: The start of the pandemic was associated with overall decreases in the mean number of prenatal care visits, decreases in hospital birth rates, and increases in labor induction rates. The mean number of prenatal care visits decreased similarly for all racial‒ethnic groups, whereas reductions in hospital births were largest for non-Hispanic White individuals, and increases in labor induction were largest for non-Hispanic White and non-Hispanic Asian or Pacific Islander individuals. CONCLUSIONS: Among all U.S. live births, the COVID-19 pandemic was associated with modest overall changes in perinatal care, with differential changes by maternal race‒ethnicity. Differential changes in perinatal services may have implications for racial-ethnic maternal health disparities.

State-Level Variation in Supplemental Maternity Kick Payments in Medicaid Managed Care.

This cross-sectional study assesses the prevalence and magnitude of state-level delivery event­triggered kick payments to Medicaid managed care plans and their association with delivery costs.

Changes in Postpartum Insurance Coverage in the US During the COVID-19 Pandemic.

This cross-sectional study examines changes in postpartum insurance churn during the COVID-19 pandemic.

Presumptive eligibility for pregnancy Medicaid and timely prenatal care access.

OBJECTIVE: To assess the association between the adoption of presumptive eligibility for pregnancy Medicaid in Kansas in 2016 and timely prenatal care access. DATA SOURCE: 2012-2019 National Center for Health Statistics natality files. STUDY DESIGN: We used difference-in-differences to compare outcomes before (2012-2015) and after (2017-2019) presumptive eligibility in Kansas relative to seven control group states overall and stratified by maternal education. Outcomes included first-trimester prenatal care, the month of first prenatal visit, and adequate prenatal care. DATA COLLECTION/EXTRACTION METHODS: All live births among adults aged 20 or older in Kansas, Idaho, Missouri, Nebraska, Tennessee, Utah, Wisconsin, and Wyoming. PRINCIPAL FINDINGS: Among all births, we found no evidence that presumptive eligibility in Kansas resulted in changes in prenatal care use. Among individuals with high school education or less, presumptive eligibility was associated with a 1.92 percentage-point increase (95% CI: 0.64, 4.35) in first-trimester prenatal care, driven by earlier month of first prenatal care visit. CONCLUSIONS: Presumptive eligibility in Medicaid non-expansion states may lead to small improvements in early prenatal care among individuals with lower education, but other interventions may be needed.

Association Between Medicaid Expansion And Closure Of Hospital-Based Obstetric Services.

Access to obstetric services has declined steadily during the past decade, driven by the closure of hospital-based obstetric units and of entire hospitals. A fundamental challenge to maintaining obstetric services is that they are frequently unprofitable for hospitals to operate, threatening hospital viability. Medicaid expansion has emerged as a possible remedy for obstetric service closure because it reduces uncompensated care and improves hospital finances. Using national hospital data from the period 2010-18, we assessed the relationship between Medicaid expansion and obstetric service closure in rural and urban communities. We found that expansion led to a large reduction in hospital closures; however, this effect was concentrated among hospitals that did not have obstetric units. Considering closure of obstetric units, we found that rural obstetric units were less likely to close immediately after expansion, but this effect faded within two years. Overall, our findings suggest that Medicaid expansion had little effect on the closure of obstetric services. Policies supporting access to obstetric care may need to directly address the financial challenges specific to this service line.
