State Public Insurance Coverage Policies and Postpartum Care Among Immigrants.

Importance: Professional medical organizations recommend that adults receive routine postpartum care. Yet, some states restrict public insurance coverage for undocumented immigrants and recently documented immigrants (those who received legal documentation status within the past 5 years). Objective: To examine the association between public insurance coverage and postpartum care among low-income immigrants and the difference in receipt of postpartum care among immigrants relative to nonimmigrants. Design, Setting, and Participants: A pooled, cross-sectional analysis was conducted using data from the Pregnancy Risk Assessment Monitoring System for 19 states and New York City including low-income adults with a live birth between 2012 and 2019. Exposure: Giving birth in a state that offered public insurance coverage for postpartum care to recently documented or undocumented immigrants. Main Outcomes and Measures: Self-reported receipt of postpartum care by the category of coverage offered (full coverage: states that offered publicly funded postpartum care regardless of immigration status; moderate coverage: states that offered publicly funded postpartum care to lawfully residing immigrants without a 5-year waiting period, but did not offer postpartum care to undocumented immigrants; no coverage: states that did not offer publicly funded postpartum care to lawfully present immigrants before 5 years of legal residence or to undocumented immigrants). Results: The study included 72 981 low-income adults (20 971 immigrants [29%] and 52 010 nonimmigrants [71%]). Of the 19 included states and New York City, 6 offered full coverage, 9 offered moderate coverage, and 4 offered no coverage; 1 state (Oregon) switched from offering moderate coverage to offering full coverage. Compared with the states that offered full coverage, receipt of postpartum care among immigrants was 7.0-percentage-points lower (95% CI, -10.6 to -3.4 percentage points) in the states that offered moderate coverage and 11.3-percentage-points lower (95% CI, -13.9 to -8.8 percentage points) in the states that offered no coverage. The differences in the receipt of postpartum care among immigrants relative to nonimmigrants were also associated with the coverage categories. Compared with the states that offered full coverage, there was a 3.3-percentage-point larger difference (95% CI, -5.3 to -1.4 percentage points) in the states that offered moderate coverage and a 7.7-percentage-point larger difference (95% CI, -10.3 to -5.0 percentage points) in the states that offered no coverage. Conclusions and Relevance: Compared with states without insurance restrictions, immigrants living in states with public insurance restrictions were less likely to receive postpartum care. Restricting public insurance coverage may be an important policy-driven barrier to receipt of recommended pregnancy care and improved maternal health among immigrants.

Cholera surveillance during the Haiti epidemic--the first 2 years.

BACKGROUND: In October 2010, nearly 10 months after a devastating earthquake, Haiti was stricken by epidemic cholera. Within days after detection, the Ministry of Public Health and Population established a National Cholera Surveillance System (NCSS). METHODS: The NCSS used a modified World Health Organization case definition for cholera that included acute watery diarrhea, with or without vomiting, in persons of all ages residing in an area in which at least one case of Vibrio cholerae O1 infection had been confirmed by culture. RESULTS: Within 29 days after the first report, cases of V. cholerae O1 (serotype Ogawa, biotype El Tor) were confirmed in all 10 administrative departments (similar to states or provinces) in Haiti. Through October 20, 2012, the public health ministry reported 604,634 cases of infection, 329,697 hospitalizations, and 7436 deaths from cholera and isolated V. cholerae O1 from 1675 of 2703 stool specimens tested (62.0%). The cumulative attack rate was 5.1% at the end of the first year and 6.1% at the end of the second year. The cumulative case fatality rate consistently trended downward, reaching 1.2% at the close of year 2, with departmental cumulative rates ranging from 0.6% to 4.6% (median, 1.4%). Within 3 months after the start of the epidemic, the rolling 14-day case fatality rate was 1.0% and remained at or below this level with few, brief exceptions. Overall, the cholera epidemic in Haiti accounted for 57% of all cholera cases and 53% of all cholera deaths reported to the World Health Organization in 2010 and 58% of all cholera cases and 37% of all cholera deaths in 2011. CONCLUSIONS: A review of NCSS data shows that during the first 2 years of the cholera epidemic in Haiti, the cumulative attack rate was 6.1%, with cases reported in all 10 departments. Within 3 months after the first case was reported, there was a downward trend in mortality, with a 14-day case fatality rate of 1.0% or less in most areas.

Extended Postpartum Medicaid In Colorado Associated With Increased Treatment For Perinatal Mood And Anxiety Disorders.

Perinatal mood and anxiety disorders (PMAD), a leading cause of perinatal morbidity and mortality, affect approximately one in seven births in the US. To understand whether extending pregnancy-related Medicaid eligibility from sixty days to twelve months may increase the use of mental health care among low-income postpartum people, we measured the effect of retaining Medicaid as a low-income adult on mental health treatment in the postpartum year, using a "fuzzy" regression discontinuity design and linked all-payer claims data, birth records, and income data from Colorado from the period 2014-19. Relative to enrolling in commercial insurance, retaining postpartum Medicaid enrollment was associated with a 20.5-percentage-point increase in any use of prescription medication or outpatient mental health treatment, a 16.0-percentage-point increase in any use of prescription medication only, and a 7.3-percentage-point increase in any use of outpatient mental health treatment only. Retaining postpartum Medicaid enrollment was also associated with $40.84 lower out-of-pocket spending per outpatient mental health care visit and $3.24 lower spending per prescription medication for anxiety or depression compared with switching to commercial insurance. Findings suggest that extending postpartum Medicaid eligibility may be associated with higher levels of PMAD treatment among the low-income postpartum population.

Medicaid Expansion Led To Reductions In Postpartum Hospitalizations.

The Affordable Care Act (ACA) Medicaid expansions increased preconception and postpartum insurance coverage among low-income birthing people, leading to greater use of outpatient care. In this study we evaluated whether the expansions affected rates of postpartum hospitalization. Our analyses took advantage of underused longitudinal hospital data from the period 2010-17 to examine hospitalizations after childbirth. We compared changes in hospitalizations among birthing people with a Medicaid-financed delivery in states that did and did not expand Medicaid under the ACA. We found a 17 percent reduction in hospitalizations during the first sixty days postpartum associated with the Medicaid expansions and some evidence of a smaller decrease in hospitalizations between sixty-one days and six months postpartum. Our findings indicate that expanding Medicaid coverage led to improved postpartum health for low-income birthing people.

Association Between the Coronavirus Disease 2019 (COVID-19) Pandemic and National Disparities in Postpartum Visit Attendance.

This study used data from PRAMS (Pregnancy Risk Assessment Monitoring System) between 2016 and 2020 and found that postpartum visit attendance declined by 5.8 (95% CI -6.4 to -5.2) percentage points in the first 9 months of the coronavirus disease 2019 (COVID-19) pandemic. The greatest declines occurred among non-Hispanic Black individuals (-9.9, 95% CI -11.6 to -8.1 percentage points), individuals aged 19 years or younger (-9.9, 95% CI -13.5 to -6.2 percentage points), and individuals without postpartum insurance (-11.4, 95% CI -14.5 to -8.3 percentage points). Although the pandemic was associated with a decrease in reporting common barriers to attendance, including lack of transportation and not being able to leave work, it introduced new barriers that potentially contributed to widened disparities in postpartum care. A combination of health policy and health system approaches are needed to increase postpartum visit attendance and reduce disparities in use.

Association of Medicaid Expansion With Postpartum Depression Treatment in Arkansas.

Importance: Postpartum depression affects approximately 1 in every 8 postpartum individuals in the US. Antidepressant medication can effectively treat postpartum depression. However, gaps in postpartum insurance coverage after the end of Medicaid pregnancy coverage at 60 days postpartum may limit treatment uptake and decrease continuity of postpartum depression treatment. Objective: To examine the association of Medicaid expansion in Arkansas with postpartum antidepressant prescription fills and antidepressant continuation and supply during the first 6 months postpartum. Design, Setting, and Participants: Cohort study with a difference-in-differences analysis comparing persons with Medicaid and commercially financed childbirth using Arkansas' All-Payer Claims Database (2013-2016). Analysis was completed between July 2021 and June 2022. Exposures: Medicaid-paid childbirth after January 1, 2014. Main Outcomes and Measures: Antidepressant medication prescription fills and the number of days of antidepressant supply in the early (first 60 days after childbirth) and the late (61 days to 6 months after childbirth) postpartum periods. Results: In this cohort study with a difference-in-differences analysis of 60 990 childbirths (mean [SD] birthing parent's age, 27 [5.3] years; 22% Black, 7% Hispanic, 67% White individuals), 72% of births were paid for by Medicaid and 28% were paid for by a commercial payer. Before expansion, 4.2% of people with a Medicaid-paid birth filled an antidepressant prescription in the later postpartum period. Medicaid expansion was associated with a 4.6 percentage point (95% CI, 2.9-6.3) increase in the likelihood, or a relative change of 110%, in this outcome. Before expansion, among people with postpartum depression in the early postpartum period with a Medicaid-paid birth, 32.7% filled an antidepressant prescription in the later postpartum period, and had an average of 23 days of antidepressant prescription supply during the later postpartum period. Among people with early postpartum depression, Medicaid expansion increased the continuity of antidepressant treatment by 20.5 percentage points (95% CI, 14.1-26.9) and the number of days with antidepressant supply in the later postpartum period by 14.1 days (95% CI, 7.2-20.9). Conclusions and Relevance: Medicaid expansion in Arkansas was associated with an increase in postpartum antidepressant prescription fills, and an increase in antidepressant treatment continuity and medication supply in the period after Medicaid pregnancy-related eligibility ended.

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.

Differences in Use of Fertility Treatment Between People With Medicaid and Private Health Insurance Coverage in the United States.

OBJECTIVES: We aimed to compare differences in receipt of any and specific types of fertility services between people with Medicaid and private insurance. METHODS: We used National Survey of Family Growth (2002-2019) data and linear probability regression models to examine the association between insurance type (Medicaid or private) and fertility service use. The primary outcome was use of fertility services in the past 12 months, and secondary outcomes were use of specific types of fertility services at any time: 1) testing, 2) common medical treatment, and 3) use of any fertility treatment type (testing, medical treatment, or surgical treatment of infertility). We additionally calculated time-to-pregnancy using a method that estimates the unobserved total amount of time the respondent spent trying to become pregnant using their current duration of pregnancy attempt at the time of the survey. We calculated time-to-pregnancy ratios across respondent characteristics to examine if insurance type was associated with differential time-to-pregnancy. RESULTS: In adjusted models, Medicaid coverage was associated with an 11.2-percentage point (95% confidence interval: -22.3 to -0.0) lower use of fertility services in the past 12 months compared with private coverage. Relative to private coverage, Medicaid insurance was also associated with large and statistically significantly lower rates of ever having used infertility testing or any fertility services. Insurance type was not associated with differences in time-to-pregnancy. CONCLUSIONS: People covered by Medicaid were less likely to have used fertility services compared with people with private insurance. Differences in coverage of fertility services between Medicaid and private payers may represent a barrier to fertility treatment for Medicaid recipients.

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.

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.

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.

Association of Medicaid Reimbursement for Immediate Postpartum Long-acting Reversible Contraception With Infant Birth Outcomes.

IMPORTANCE: Together, preterm birth and low birth weight are the second-leading cause of infant mortality in the US and occur disproportionately among Medicaid-paid births and among the infants of Black birthing persons. In 2012, South Carolina's Medicaid program began to reimburse hospitals for immediate postpartum long-acting reversible contraception (LARC) separately from the global maternity payment. OBJECTIVE: To examine the association between South Carolina's policy change and infant health. DESIGN, SETTING, AND PARTICIPANTS: This population-based cohort study using a difference-in-differences analysis included individuals with a South Carolina Medicaid-paid childbirth between January 2009 and December 2015. Data were analyzed from December 2020 to July 2021. EXPOSURES: Medicaid-paid childbirth after March 2012 in South Carolina hospitals that had implemented the policy. MAIN OUTCOMES AND MEASURES: Immediate postpartum LARC uptake, subsequent birth within 4 years, subsequent short-interval birth, days to subsequent birth, subsequent preterm, and low-birth-weight birth within 4 years. RESULTS: The study sample included 186 953 Medicaid-paid births between January 2009 and December 2015 in South Carolina (81 110 births from 2009 to 2011, 105 843 births from 2012 to 2015, and 46 414 births in exposure hospitals). The policy was associated with an absolute 5.6-percentage point (95% CI, 3.7-7.4) increase in the probability of receiving an immediate postpartum LARC overall, with significantly larger effects for non-Hispanic Black individuals than non-Hispanic White individuals (difference in coefficients 3.54; 95% CI, 1.35-5.73; P = .002). The policy was associated with a 0.4-percentage point (95% CI, -0.7 to -0.1) decrease in the probability of subsequent preterm birth and a 0.3-percentage point (95% CI, -0.7 to 0) decrease in the probability of subsequent low birth weight. No significant difference in the association between the policy and preterm birth or low-birth-weight birth between non-Hispanic Black and non-Hispanic White individuals was found. The policy was associated with a 0.6-percentage point (95% CI, -1.2 to -0.1) decrease in the probability of short-interval birth and a 27-day (95% CI, 11-44) increase in days to next birth among non-Hispanic Black individuals. The policy was associated with a significant decrease in the probability of a subsequent birth overall; however, confidence in this result is attenuated somewhat by nonparallel trends for this outcome before the policy change. CONCLUSIONS AND RELEVANCE: Findings of this cohort study suggest policies increasing access to immediate postpartum LARC may improve birth outcomes but should be accompanied by other policy efforts to reduce inequity in these outcomes.

Association of the affordable care act Medicaid expansions with postpartum contraceptive use and early postpartum pregnancy.

OBJECTIVES: Before the Affordable Care Act (ACA), 55% of individuals giving birth with Medicaid lost insurance postpartum, potentially affecting their access to postpartum contraception. We evaluate the association of the ACA Medicaid expansions with postpartum contraceptive use and pregnancy at the time of the survey. METHODS: We used 2012-2019 Pregnancy Risk Assessment Monitoring System data to estimate difference-in-difference models for the association of Medicaid expansions with the use of postpartum contraception (mean: 4 months postpartum): any contraception, long-acting reversible contraception, or LARC (contraceptive implant and intrauterine device), short-acting (contraceptive pill, patch, and ring), permanent, or non-prescription methods (condoms, rhythm method, and withdrawal), and pregnancy at the time of the survey. We examine low-income respondents overall and stratified by race and ethnicity. RESULTS: We find that Medicaid expansion was associated with a 7.0 percentage point (95% CI: 3.0, 11.0) increase in postpartum LARC, a 3.1 percentage point (95% CI: -6.0, -0.2) decrease in short-acting contraception, and a 3.9 percentage point (95% CI: -6.2, -1.5) decrease in non-prescription contraceptive use overall. In stratified analyses, we find that increases in LARC use were concentrated among non-Hispanic White and Black respondents, with shifts in other postpartum contraceptives towards LARCs. Medicaid expansion was associated with a decrease in early postpartum pregnancy only among non-Hispanic Black respondents. CONCLUSIONS: Medicaid expansions led to shifts from methods with a lower upfront out-of-pocket cost for people without insurance towards methods with the higher upfront out-of-pocket cost for people without insurance. These changes suggest that Medicaid expansion improved postpartum contraceptive access. IMPLICATIONS: These findings indicate that postpartum uninsurance was a barrier to postpartum contraceptive access prior to Medicaid expansions under the Affordable Care Act. Medicaid expansions increased access to the full range of contraceptive methods.

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.

Immediate Postpartum Long-Acting Reversible Contraceptive Use Following State-Specific Changes in Hospital Medicaid Reimbursement.

Importance: Facilitating access to the full range of contraceptive options is a health policy goal; however, inpatient provision of postpartum long-acting reversible contraceptive (LARC) methods has been limited due to lack of hospital reimbursement. Between March 2014 and January 2015, the Medicaid programs in 5 states began to reimburse hospitals for immediate postpartum LARC separately from the global maternity payment. Objective: To examine the association between Medicaid policies and provision of immediate postpartum LARC, and to examine hospital characteristics associated with policy adoption. Design, Setting, and Participants: This cross-sectional study used interrupted time series analysis. The setting was population-based in Georgia, Iowa, Maryland, New York, and Rhode Island. Participants included individuals who gave birth in these states between 2011 and 2017 (n = 3 097 188). Statistical analysis was performed from June 2021 to August 2022. Exposures: Childbirth after the start of Medicaid's reimbursement policy. Main Outcomes and Measures: Immediate postpartum LARC (outcome), teaching hospital, Catholic-owned or operated, obstetrical care level, and urban or rural location (hospital characteristics). Results: The study included a total of 1 521 491 births paid for by Medicaid and 1 575 697 paid for by a commercial payer between 2011 and 2017. Prior to Medicaid reimbursement changes, 489 389 of 726 805 births (67%) were to individuals between 18 and 29 years of age, 219 363 of 715 905 births (31%) were to non-Hispanic Black individuals, 227 639 of 715 905 births (32%) were to non-Hispanic White individuals, 155 298 of 715 905 births (22%) were to Hispanic individuals, and 113 605 of 715 905 births (16%) were to individuals from other non-Hispanic racial groups. Among Medicaid-paid births, the policies were associated with an increase in the rate of immediate postpartum LARC provision in all states, although results for Maryland were not consistent across sensitivity analyses. The change in trend ranged from a quarterly increase of 0.05 percentage points in Maryland (95% CI, 0.01-0.08 percentage points) and 0.05 percentage points in Iowa (95% CI, 0.00-0.11 percentage points) to 0.82 percentage points (95% CI, 0.73-0.91 percentage points) in Rhode Island. The policy was also associated with an increase in immediate postpartum LARC provision among commercially paid births in 4 of 5 states. After the policy, only 38 of 366 hospitals (10%) provided more than 1% of birthing people with immediate postpartum LARC. These adopting hospitals were less likely to be Catholic (0% [0 of 31] vs 17% [41 of 245]), less likely to be rural (10% [3 of 31] vs 33% [81 of 247]), more likely to have the highest level of obstetric care (71% [22 of 31] vs 29% [65 of 223]) and be teaching hospitals (87% [27 of 31] vs 43% [106 of 246]) compared with nonadopting hospitals. Conclusions and Relevance: This cross-sectional study's findings suggest that Medicaid policies that reimburse immediate postpartum LARC may increase access to this service; however, policy implementation has been uneven, resulting in unequal access.

Trends in postpartum mental health care before and during COVID-19.

OBJECTIVE: To assess the impact of COVID-19 on trends in postpartum mental health diagnoses and utilization of psychotherapy and prescription drug treatment. DATA SOURCES: Data were obtained from a large, national health insurance claims database that tracks individuals longitudinally. STUDY DESIGN: We used interrupted time series models to examine changes in trends of postpartum mental health diagnoses before and during the COVID-19 pandemic and t-tests to examine differences in treatment. DATA EXTRACTION METHODS: We used billing codes to identify individuals who received mental health-related diagnoses and treatment in the first 90 days after a birth hospitalization. We excluded individuals diagnosed with schizophrenia or bipolar disorder and those with an unknown payer at delivery. PRINCIPAL FINDINGS: Compared to the pre-pandemic period, the trend in new postpartum mental health diagnoses increased significantly in the post-COVID-19 period (0.06 percentage points [95%CI 0.01, 0.11]). Over 12 months, the percentage of new diagnoses was 5.0% greater relative to what would be expected in absence of COVID-19. The percentage of diagnosed individuals who did not receive treatment increased from 50.4% to 52.7% (p = 0.003). CONCLUSIONS: Findings point to an urgent need to improve screening and treatment pathways for perinatal individuals in the wake of COVID-19.

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.

Medicaid Payments For Immediate Postpartum Long-Acting Reversible Contraception: Evidence From South Carolina.

In 2012 South Carolina's Medicaid program was the first state Medicaid program to separate payment for the immediate postpartum placement of long-acting reversible contraception (intrauterine devices and contraceptive implants) from its global maternity payment. Examining data on all Medicaid-insured South Carolina women giving birth from 2010 to 2014, we found that the new policy achieved its explicit goal: increasing the availability of immediate postpartum long-acting reversible contraception. Among adolescents, for whom most pregnancies are unintended, this represented new use of long-acting reversible options, rather than substitution for sterilization or for short-acting reversible methods. Therefore, the new policy also significantly increased use of highly effective postpartum contraception in an age group that is particularly vulnerable to closely spaced, higher-risk repeat pregnancies. However, fewer than half of facilities began to offer immediate postpartum long-acting reversible contraceptives after the policy change. Additional policy approaches may be needed to achieve widespread availability of this option.

Health Care Use by Commercially Insured Postpartum and Nonpostpartum Women in the United States.

OBJECTIVE: To compare the type, frequency, and timing of health care use among commercially insured postpartum and nonpostpartum women. METHODS: This retrospective cohort study used data from a large national commercial claims database. Women between 18 and 44 years of age who gave birth in 2016 (n=149,563) and women who were neither pregnant nor postpartum between 2015 and 2017 (n=2,048,831) (nonpostpartum) were included. We examined hospitalization, and preventive visits, problem visits, and emergency department (ED) visits among postpartum women during the early postpartum period (less than 21 days after childbirth), the postpartum period (21-60 days postpartum), and extended postpartum period (61-365 days after childbirth). Visits among nonpostpartum women were assessed during time periods of equivalent duration. RESULTS: Almost 24% of postpartum women had a problem visit in the early postpartum period, compared with 19.7% of nonpostpartum women (adjusted difference 4.8 percentage points [95% CI 4.6-5.0]). Approximately 3% of postpartum women had an early ED visit, more than double the percentage among nonpostpartum women (adjusted difference 2.3 percentage points [95% CI 2.2-2.4]). Both problem visits and ED visits among postpartum women remained elevated relative to nonpostpartum women during the postpartum and extended postpartum periods. Although postpartum women were more likely than nonpostpartum women to receive preventive care during the early and postpartum periods, only 43% of postpartum women had a preventive visit during the extended postpartum period, a rate 1.8 (95% CI -2.1 to -1.5) percentage points lower than that of nonpostpartum women. Adjusted hospitalization rates among postpartum women in the early (0.8%), postpartum (0.3%), and extended postpartum (1.4%) periods were higher than those of nonpostpartum women (0.1%, 0.2%, and 1.6%, respectively). CONCLUSIONS: Commercially insured postpartum women use more health care than nonpostpartum women, including inpatient care. Differences are largest in the early postpartum period and persist beyond 60 days postpartum.
