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.

Virtual Obstetric Hospitalist Support for Obstetric Emergencies and Deliveries: The Mayo Clinic Experience.

Objective: To implement use of obstetric (OB) hospitalist telemedicine services (TeleOB) to support clinicians facing OB emergencies in low-resource hospital settings. Methods: TeleOB was staffed by OB hospitalists working at a tertiary maternity center. The service was available via real-time high-definition audio/video technology for providers at 17 outlying hospitals across a health system spanning two states. The initial 25 service activations are described. Results: TeleOB supported 17 deliveries, two postpartum emergency department (ED) consultations, and four antenatal ED consultations. In 10 of 17 (59%) deliveries, teleneonatology was jointly activated to support neonatal resuscitation. Sixteen (94%) deliveries occurred in multiparas, and five (29%) resulted from spontaneous preterm labor. Eighty percent (20/25) of activations occurred in facilities without maternity services. Conclusions: A TeleOB service staffed by OB hospitalists successfully supports hospitals in an integrated health care system. TeleOB is feasible for support of hospitals with no delivery facilities or with limited maternity care resources.

Validity of Birth Certificate Data Compared With Hospital Discharge Data in Reporting Maternal Morbidity and Disparities.

A growing number of studies are using birth certificate data, despite data-quality concerns, to study maternal morbidity and associated disparities. We examined whether conclusions about the incidence of maternal morbidity, including Black-White disparities, differ between birth certificate data and hospitalization data. Using linked birth certificate and hospitalization data from California and Michigan for 2018 (N=543,469), we found that maternal morbidity measures using birth certificate data alone are substantially underreported and have poor validity. Furthermore, the degree of underreporting in birth certificate data differs between Black and White individuals and results in erroneous inferences about disparities. Overall, Black-White disparities were more modest in the birth certificate data compared with the hospitalization data. Birth certificate data alone are inadequate for studies of maternal morbidity and associated racial disparities.

Perinatal Care Measures Are Incomplete If They Do Not Assess The Birth Parent-Infant Dyad As A Whole.

Measures of perinatal care quality and outcomes often focus on either the birth parent or the infant. We used linked vital statistics and hospital discharge data to describe a dyadic measure (including both the birth parent and the infant) for perinatal care during the birth hospitalization. In this five-state cohort of 2010-18 births, 21.6 percent of birth parent-infant dyads experienced at least one complication, and 9.6 percent experienced a severe complication. Severe infant complications were eight times more prevalent than severe birth parent complications. Among birth parents with a severe complication, the co-occurrence of a severe infant complication ranged from 2 percent to 51 percent, whereas among infants with a severe complication, the co-occurrence of a severe birth parent complication was rare, ranging from 0.04 percent to 5 percent. These data suggest that measures, clinical interventions, public reporting, and policies focused on either the birth parent or the infant are incomplete in their assessment of a healthy dyad. Thus, clinicians, administrators, and policy makers should evaluate dyadic measures, incentivize positive outcomes for both patients (parent and infant), and create policies that support the health of the dyad.

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.

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.

Racial/ethnic disparities in costs, length of stay, and severity of severe maternal morbidity.

BACKGROUND: In contrast to other high-resource countries, the United States has experienced increases in the rates of severe maternal morbidity. In addition, the United States has pronounced racial and ethnic disparities in severe maternal morbidity, especially for non-Hispanic Black people, who have twice the rate as non-Hispanic White people. OBJECTIVE: This study aimed to examine whether the racial and ethnic disparities in severe maternal morbidity extended beyond the rates of these complications to include disparities in maternal costs and lengths of stay, which could indicate differences in the case severity. STUDY DESIGN: This study used California's linkage of birth certificates to inpatient maternal and infant discharge data for 2009 to 2011. Of the 1.5 million linked records, 250,000 were excluded because of incomplete data, for a final sample of 1,262,862. Cost-to-charge ratios were used to estimate costs from charges (including readmissions) after adjusting for inflation to December 2017. Mean diagnosis-related group-specific reimbursement was used to estimate physician payments. We used the Centers for Disease Control and Prevention definition of severe maternal morbidity, including readmissions up to 42 days after delivery. Adjusted Poisson regression models estimated the differential risk of severe maternal morbidity for each racial or ethnic group, compared with the non-Hispanic White group. Generalized linear models estimated the associations of race and ethnicity with costs and length of stay. RESULTS: Asian or Pacific Islander, Non-Hispanic Black, Hispanic, and other race or ethnicity patients all had higher rates of severe maternal morbidity than non-Hispanic White patients. The largest disparity was between non-Hispanic White and non-Hispanic Black patients, with unadjusted overall rates of severe maternal morbidity of 1.34% and 2.62%, respectively (adjusted risk ratio, 1.61; P<.001). Among patients with severe maternal morbidity, the adjusted regression estimates showed that non-Hispanic Black patients had 23% (P<.001) higher costs (marginal effect of $5023) and 24% (P<.001) longer hospital stays (marginal effect of 1.4 days) than non-Hispanic White patients. These effects changed when cases, such as cases where a blood transfusion was the only indication of severe maternal morbidity, were excluded, with 29% higher costs (P<.001) and 15% longer length of stay (P<.001). For other racial and ethnic groups, the increases in costs and length of stay were smaller than those observed for non-Hispanic Black patients, and many were not significantly different from non-Hispanic White patients. Hispanic patients had higher rates of severe maternal morbidity than non-Hispanic White patients; however, Hispanic patients had significantly lower costs and length of stay than non-Hispanic White patients. CONCLUSION: There were racial and ethnic differences in the costs and length of stay among patients with severe maternal morbidity across the groupings that we examined. The differences were especially large for non-Hispanic Black patients compared with non-Hispanic White patients. Non-Hispanic Black patients experienced twice the rate of severe maternal morbidity; in addition, the higher relative costs and longer lengths of stay for non-Hispanic Black patients with severe maternal morbidity support greater case severity in that population. These findings suggest that efforts to address racial and ethnic inequities in maternal health need to consider differences in case severity in addition to the differences in the rates of severe maternal morbidity and that these differences in case severity merit additional investigation.

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.

Screening for and Experiences of Intimate Partner Violence in the United States Before, During, and After Pregnancy, 2016-2019.

Objectives. To measure rates of intimate partner violence (IPV) screening during the perinatal period among people experiencing physical violence in the United States. Methods. We used 2016-2019 Pregnancy Risk Assessment Monitoring System data (n = 158 338) to describe the incidence of physical IPV before or during pregnancy. We then assessed the prevalence of IPV screening before, during, or after pregnancy and predictors of receiving screening among those reporting violence. Results. Among the 3.5% (n = 6259) of respondents experiencing violence, 58.7%, 26.9%, and 48.3% were not screened before, during, or after pregnancy, respectively. Those reporting Medicaid or no insurance at birth, American Indian/Alaska Native people, and Spanish-speaking Hispanic people faced increased risk of not having a health care visit during which screening might occur. Among those attending a health care visit, privately insured people, rural residents, and non-Hispanic White respondents faced increased risk of not being screened. Conclusions. Among birthing people reporting physical IPV, nearly half were not screened for IPV before or after pregnancy. Public health efforts to improve maternal health must address both access to care and universal screening for IPV. (Am J Public Health. 2023;113(3):297-305. https://doi.org/10.2105/10.2105/AJPH.2022.307195).

Comparison of Maternal and Neonatal Subspecialty Care Provision by Hospital.

OBJECTIVE: The aim of the study is to determine the relationship between a hospital's provision of subspecialty neonatal and maternal care. Specifically, we sought to understand where women with high-risk maternal conditions received intrapartum care and estimate the potential transfer burden for those with maternal high-risk conditions delivering at hospitals without subspecialty maternal care. STUDY DESIGN: This is a descriptive study using data from 2015 State Inpatient Databases and the American Hospital Association Annual Survey. Characteristics were compared between hospitals based on the concordance of their maternal and neonatal care. The incidences of high-risk maternal conditions (pre-eclampsia with severe features, placenta previa with prior cesarean delivery, cardiac disease, pulmonary edema, and acute liver failure) were compared. To determine the potential referral burden, the percent of women with high-risk conditions delivering at a hospital without subspecialty maternal care but delivering in a county with a hospital with subspecialty maternal care was calculated. RESULTS: The analysis included 486,398 women who delivered at 544 hospitals, of which 104 (19%) and 182 (33%) had subspecialty maternal and neonatal care, respectively. Ninety-eight hospitals provided both subspecialty maternal and neonatal care; however, 84 hospitals provided only subspecialty neonatal care but no subspecialty maternal care. Among high-risk maternal conditions examined, approximately 65% of women delivered at a hospital with subspecialty maternal care. Of the remainder who delivered at a hospital without subspecialty maternal care, one-third were in a county where subspecialty care was present. For women with high-risk conditions who delivered in a county without subspecialty maternal care, the median distance to the closest county with subspecialty care was 52.8 miles (IQR: 34.3-87.7 miles). CONCLUSION: Approximately 50% of hospitals with subspecialty neonatal care do not provide subspecialty maternal care. This discordance may present a challenge when both high-risk maternal and neonatal conditions are present. KEY POINTS: · High-risk women who deliver at hospitals without subspecialty care are in more rural areas.. · Approximately 50% of hospitals with subspecialty neonatal care do not provide subspecialty maternal care.. · This discordance may present a challenge when both high-risk maternal and neonatal conditions are present..

Understanding categories of postpartum care use among privately insured patients in the United States: a cluster-analytic approach.

The postpartum period is critical for the health and well-being of birthing people, yet little is known about the range of health care services and supports needed during this time. Maternity care patients are often targeted for clinical interventions based on "low risk" or "high risk" designations, but dichotomized measures can be imprecise and may not reflect meaningful groups for understanding needed postpartum care. Using claims data from privately insured patients with childbirths between 2016 and 2018, this study identifies categories and predictors of postpartum care utilization, including the use of maternal care and other, nonmaternal, care (eg, respiratory, digestive). We then compare identified utilization-based categories with typical high- and low-risk designations. Among 269 992 patients, 5 categories were identified: (1) low use (55% of births); (2) moderate maternal care use, low other care use (25%); (3) moderate maternal, high other (8%); (4) high maternal, moderate other (7%); and (5) high maternal, high other (5%). Utilization-based categories were better at differentiating postpartum care use and were more consistent across patient profiles, compared with high- and low-risk dichotomies. Identifying categories of postpartum care need beyond a simple risk dichotomy is warranted and can assist in maternal health services research, policymaking, and clinical practice.

The time after childbirth is important for the health of a parent who has just given birth, and postpartum experiences and needs vary widely. We studied health care data for privately insured people who gave birth and identified 5 categories of health care use in the postpartum period. None of the categories we uncovered fit the common model of a single visit at 6 weeks postpartum as the sole care needed or used postpartum. Typically, patients are divided into high-risk and low-risk groups, but our research shows that this is insufficient and masks important differences among patients within these dichotomous groups. Using advanced statistical methods to identify categories of health care use after childbirth may improve postpartum health by better targeting resources to those who need them the most.

Association of Health Insurance, Geography, and Race and Ethnicity With Disparities in Receipt of Recommended Postpartum Care in the US.

Importance: Little is known about the quality of postpartum care or disparities in the content of postpartum care associated with health insurance, rural or urban residency, and race and ethnicity. Objectives: To examine receipt of recommended postpartum care content and to describe variations across health insurance type, rural or urban residence, and race and ethnicity. Design, Settings, and Participants: This cross-sectional survey of patients with births from 2016 to 2019 used data from the Pregnancy Risk Assessment Monitoring System (43 states and 2 jurisdictions). A population-based sample of patients conducted by state and local health departments in partnership with the Centers for Disease Control and Prevention were surveyed about maternal experiences 2 to 6 months after childbirth (mean weighted response rate, 59.9%). Patients who attended a postpartum visit were assessed for content at that visit. Analyses were performed November 2021 to July 2022. Exposures: Medicaid or private health insurance, rural or urban residence, and race and ethnicity (non-Hispanic White or racially minoritized groups). Main Outcomes and Measures: Receipt of 2 postpartum care components recommended by national quality standards (depression screening and contraceptive counseling), and/or other recommended components (smoking screening, abuse screening, birth spacing counseling, eating and exercise discussions) with estimated risk-adjusted predicted probabilities and percentage-point (pp) differences. Results: Among the 138 073 patient-respondents, most (59.5%) were in the age group from 25 to 34 years old; 59 726 (weighted percentage, 40%) were insured by Medicaid; 27 721 (15%) were rural residents; 9718 (6%) were Asian, 24 735 (15%) were Black, 22 210 (15%) were Hispanic, 66 323 (60%) were White, and fewer than 1% were Indigenous (Native American/Alaska Native) individuals. Receipt of both depression screening and contraceptive counseling both significantly lower for Medicaid-insured patients (1.2 pp lower than private; 95% CI, -2.1 to -0.3), rural residents (1.3 pp lower than urban; 95% CI, -2.2 to -0.4), and people of racially minoritized groups (0.8 pp lower than White individuals; 95% CI, -1.6 to -0.1). The highest receipt of these components was among privately insured White urban residents (80%; 95% CI, 79% to 81%); the lowest was among privately insured racially minoritized rural residents (75%; 95% CI, 72% to 78%). Receipt of all other components was significantly higher for Medicaid-insured patients (6.1 pp; 95% CI, 5.2 to 7.0), rural residents (1.1 pp; 95% CI, 0.1 to 2.0), and people of racially minoritized groups (8.5 pp; 95% CI, 7.7 to 9.4). The highest receipt of these components was among Medicaid-insured racially minoritized urban residents (34%; 95% CI, 33% to 35%), the lowest was among privately insured White urban residents (19%; 95% CI, 18% to 19%). Conclusions and Relevance: The findings of this cross-sectional survey of postpartum individuals in the US suggest that inequities in postpartum care content were extensive and compounded for patients with multiple disadvantaged identities. Examining only 1 dimension of identity may understate the extent of disparities. Future studies should consider the content of postpartum care visits.

Rural Hospital Administrators' Beliefs About Safety, Financial Viability, and Community Need for Offering Obstetric Care.

Importance: Rural obstetric unit closures are associated with adverse maternal and infant health outcomes and are most common among low-birth volume facilities located in remote areas. Declining access to obstetric care is a concern in rural communities in the US. Objective: To assess rural hospital administrators' beliefs about safety, financial viability, and community need for offering obstetric care. Design Setting and Participants: Using the American Hospital Association Annual Survey to identify rural hospitals with obstetric units, we developed and conducted a national survey of a sample of rural hospitals that provided obstetric services in 2021. Obstetric unit managers or administrators at 292 rural hospitals providing obstetric services were surveyed from March to August 2021. Exposures: Local factors, clinical safety, workforce, and financial considerations for obstetric services at participating hospitals. Main Outcomes and Measures: Hospital-level decisions on maintaining obstetric care. Results: Of the 93 total responding hospitals (32% response rate), 33 (35.5%) were critical access hospitals, 60 (64.5%) were located in micropolitan rural counties; they had a median (IQR) average daily census of 22 (10-53) patients, and 48 (52.2%) had experienced a recent decline in births, with a median (IQR) of 274 (120-446) births in 2019. Respondents reported that the minimum number of annual births needed to safely provide obstetric care was 200 (IQR, 100-350). From a financial perspective, the minimum number of annual births needed was also 200 (IQR, 120-360). When making decisions about maintaining obstetric care, 51 (64.6%) responding hospitals listed their highest priority as meeting local community needs, 13 (16.5%) listed financial considerations, and 10 (12.7%) listed staffing. Overall, 23 (25%) responding hospitals were not sure they would continue providing obstetrics, or they expected to stop offering this service. Conclusions and Relevance: In this survey of US rural hospitals that offer obstetric services, many administrators indicated prioritizing local community needs for obstetric care over concerns about financial viability and staffing.

Racial/Ethnic Disparities in Postpartum Health Insurance Coverage Among Rural and Urban U.S. Residents.

Objective: Half of maternal deaths occur during the postpartum year, with data suggesting greater risks among Black, Indigenous, and people of color (BIPOC) and rural residents. Being insured after childbirth improves postpartum health-related outcomes, and recent policy efforts focus on extending postpartum Medicaid coverage from 60 days to 1 year postpartum. The purpose of this study is to describe postpartum health insurance coverage for rural and urban U.S. residents who are BIPOC compared to those who are white. Materials and Methods: Using data from the 2016-2019 Pregnancy Risk Assessment Monitoring System (n = 150,273), we describe health insurance coverage categorized as Medicaid, commercial, or uninsured at the time of childbirth and postpartum. We measured continuity of insurance coverage across these periods, focusing on postpartum Medicaid disruptions. Analyses were conducted among white and BIPOC residents from rural and urban U.S. counties. Results: Three-quarters (75.3%) of rural white people and 85.3% of urban white people were continuously insured from childbirth to postpartum, compared to 60.5% of rural BIPOC people and 65.6% of urban BIPOC people. Postpartum insurance disruptions were frequent among people with Medicaid coverage at childbirth, particularly among BIPOC individuals, compared to those with private insurance; 17.0% of rural BIPOC residents had Medicaid at birth and became uninsured postpartum compared with 3.4% of urban white people. Conclusions: Health insurance coverage at childbirth, postpartum, and across these timepoints varies by race/ethnicity and rural compared with urban residents. Policy efforts to extend postpartum Medicaid coverage may reduce inequities at the intersection of racial/ethnic identity and rural geography.

Perinatal outcomes for rural obstetric patients and neonates in rural-located and metropolitan-located hospitals.

OBJECTIVE: To compare rural obstetric patient and neonate characteristics and outcomes by birth location. METHODS: Retrospective observational cohort study of rural residents' hospital births from California, Pennsylvania, and South Carolina. Hospitals in rural counties were rural-located, those in metropolitan counties with ≥10% of obstetric patients from rural communities were rural-serving, metropolitan-located, others were non-rural-serving, metropolitan-located. Any adverse obstetric patient or neonatal outcomes were assessed with logistic regression accounting for patient characteristics, state, year, and hospital. RESULTS: Of 466,896 rural patient births, 64.3% occurred in rural-located, 22.5% in rural-serving, metropolitan-located, and 13.1% in non-rural-serving, metropolitan-located hospitals. The odds of any adverse outcome increased in rural-serving (aOR 1.27, 95% CI 1.10-1.46) and non-rural-serving (aOR 1.35, 95% CI 1.18-1.55) metropolitan-located hospitals. CONCLUSION: One-third of rural obstetric patients received care in metropolitan-located hospitals. These patients have higher comorbidity rates and higher odds of adverse outcomes likely reflecting referral for higher baseline illness severity.

Severe Maternal Morbidity and Mortality Risk at the Intersection of Rurality, Race and Ethnicity, and Medicaid.

OBJECTIVE: We examined differences in rates of severe maternal morbidity and mortality (SMMM) among Medicaid-funded compared with privately insured hospital births through specific additive and intersectional risk by rural or urban geography, race and ethnicity, and clinical factors. METHODS: We used maternal discharge records from childbirth hospitalizations in the Healthcare Cost and Utilization Project's National Inpatient Sample from 2007 to 2015. We calculated predicted probabilities using weighted multivariable logistic regressions to estimate adjusted rates of SMMM, examining differences in rates by payer, rurality, race and ethnicity, and clinical factors. To assess the presence and extent of additive risk by payer, with other risk factors, on rates of SMMM, we estimated the proportion of the combined effect that was due to the interaction. RESULTS: In this analysis of 6,357,796 hospitalizations for childbirth, 2,932,234 were Medicaid funded and 3,425,562 were privately insured. Controlling for sociodemographic and clinical factors, the highest rate of SMMM (224.9 per 10,000 births) occurred among rural Indigenous Medicaid-funded births. Medicaid-funded births among Black rural and urban residents, and among Hispanic urban residents, also experienced elevated rates and significant additive interaction. Thirty-two percent (Bonferroni-adjusted 95% confidence interval, 19%-45%) of SMMM cases among patients with chronic heart disease were due to payer interaction, and 19% (Bonferroni-adjusted 95% confidence interval, 17%-22%) among those with cesarean birth were due to the interaction. CONCLUSIONS: Heightened rates of SMMM among Medicaid-funded births indicate an opportunity for tailored state and federal policy responses to address the particular maternal health challenges faced by Medicaid beneficiaries, including Black, Indigenous, and rural residents.

The effect of severe maternal morbidity on infant costs and lengths of stay.

OBJECTIVE: To examine the association between severe maternal morbidity (SMM) and infant health using the additional infant costs and length of stay (LOS) as markers of added clinical complexity. STUDY DESIGN: Secondary data analysis using California linked birth certificate-patient discharge data for 2009-2011 (N = 1,260,457). Regression models were used to estimate the association between SMM and infant costs and LOS. RESULTS: The 16,687 SMM-exposed infants experienced a $6550 (33%) increase in costs and a 0.7 (18%) day increase in LOS. Preterm infants had ($11,258 (18%) added costs and 1.3 days (8.1%) longer LOS) than term infants ($2539 (38%) added costs and 0.5 days (22%) longer LOS). CONCLUSIONS: SMM was associated with increased infant costs and LOS, suggesting that SMM may have adverse health effects for infants, including term infants. The relatively larger effect on costs indicates an increase in treatment intensity (clinical severity) greater than additional LOS.
