Obstetric transport in rural settings: Referral and transport of pregnant patients in a state without a perinatal regionalized system of care.

OBJECTIVE: To assess factors impacting obstetric transport and referral processes for pregnant patients experiencing an emergency in a rural state without a perinatal regionalized system of care. DATA SOURCES AND STUDY SETTING: Data is from Critical Access Hospitals (CAHs) without obstetric units and healthcare providers involved in obstetric care and transport at hospitals with varying levels of obstetric capacity in Montana. STUDY DESIGN: This mixed-methods study involved surveying CAHs without obstetric units about the hospitals' capacity for obstetric emergencies and transport policies. Survey data were collected from 32 of 34 CAHs without obstetric units (94% response rate) in the fall of 2021. Subsequent interviews were conducted in the fall and winter of 2022-2023 with 20 hospital and emergency medical services (EMS) personnel to provide further insights into the referral and transport process during obstetric emergencies. DATA COLLECTION/EXTRACTION METHODS: Survey data were collected using REDCap; interviews were conducted via videoconference. We performed descriptive statistics and Fisher's exact tests for quantitative data. We analyzed qualitative data using a three-phase pragmatic analytic approach. PRINCIPAL FINDINGS: The survey of CAHs found 12 of 32 facilities faced difficulties coordinating transport for pregnant patients. Qualitative data indicated this was often due to the state's decentralized transport system. Challenges identified through both quantitative and qualitative data included weather, securing a receiving facility/provider, and coordinating medical transport. Only 10 CAHs reported having written protocols for transporting pregnant patients; of those, four facilities had formal transfer agreements. Qualitative data emphasized variations in awareness and the utility of obstetric transport policies. CONCLUSIONS: A decentralized transport system in a rural state can exacerbate existing challenges faced by providers arranging transport for pregnant patients during an obstetric emergency. State and interfacility policies could enhance the transport process for increased regionalization as well as increased support for and coordination of existing EMS.

Postpartum long-acting reversible contraceptive adoption after a statewide initiative.

OBJECTIVES: To examine the effects of a comprehensive, multiyear (2015-2020) statewide contraceptive access intervention in Delaware on the contraceptive initiation of postpartum Medicaid patients. The program aimed to increase access to all contraceptives, including long-acting reversible contraceptives (LARC). The program included interventions specifically targeting postpartum patients (Medicaid payment reform and hospital-based immediate postpartum (IPP) LARC training) and interventions in outpatient settings (provider training and operational supports). DATA SOURCES AND STUDY SETTING: We used Medicaid claims data between 2012 and 2019, from Delaware and Maryland (a comparison state), to identify births and postpartum contraceptive methods up to 60 days postpartum among patients aged 15-44 years who were covered in a full-benefit eligibility category. STUDY DESIGN: Using difference-in-differences, we assessed changes in LARC, tubal ligation, and short-acting methods (oral contraceptive, injectable, patch/ring). LARC rates were assessed at 60 days after delivery and on an immediate postpartum basis. Other methods were only assessed at 60 days. Analyses were conducted separately for an early-adopting high-capacity hospital (that delivers approximately half of all Medicaid financed births) and for all other later-adopting hospitals in the state. DATA COLLECTION/EXTRACTION METHODS: Data were extracted from administrative claims. PRINCIPAL FINDINGS: The program increased postpartum LARC insertions by 60 days after delivery by 11.7 percentage points (95% CI: 10.7, 12.8) in the early-adopting hospital and 6.9 percentage points (95% CI: 4.8, 5.9) in later-adopting hospitals. Increases in IPP versus outpatient LARC drove the change, but we did not find evidence that IPP crowded-out outpatient LARC services. We observed decreases in short-acting methods, suggesting substitution between methods, but the share of patients with any method increased at the early-adopting hospital (5.2 percentage points; 95% CI: 3.5, 6.9) and was not statistically significantly different at the later-adopting hospitals. CONCLUSIONS: Direct reimbursement for IPP LARC, in combination with provider training, had a meaningful impact on the share of Medicaid-enrolled postpartum women with LARC claims.

A case study on variations in network structure and cross-sector alignment in two local systems serving pregnant and parenting women in recovery.

OBJECTIVE: To describe network structure and alignment across organizations in healthcare, public health, and social services sectors that serve pregnant and parenting women with substance use disorder (SUD) in an urban and a rural community. DATA SOURCES AND STUDY SETTINGS: Two community networks, one urban and one rural with each including a residential substance use treatment program, in Kentucky during 2021. STUDY DESIGN: Social network analysis measured system collaboration and cross-sector alignment between healthcare, public health, and social services organizations, applying the Framework for Aligning Sectors. To understand the alignment and structure of each network, we measured network density overall and between sectors, network centralization, and each organization's degree centrality and effective size. DATA COLLECTION/EXTRACTION METHODS: Computer-assisted telephone interviews were conducted to document alignment around shared purpose, data, financing, and governance. PRINCIPAL FINDINGS: On average, overall and cross-sector network densities in both communities were similar. However, alignment was highest for data sharing and financing in the urban community and for shared purpose and governance in the rural community. Cross-sector partnerships involving healthcare organizations were more prevalent in the rural county (44% vs. 38% for healthcare/public health, 44% vs. 29% for healthcare/social services), but more prevalent for those involving public health/social services organizations in the urban county (42% vs. 24%). A single healthcare organization had the highest degree centrality (Mdn [IQR] = 26 [26-9.5]) and effective size (Mdn [IQR] = 15.9 [20.6-8.7]) within the rural county. Social services organizations held more central positions in the urban county (degree centrality Mdn [IQR] = 13 [14.8-9.5]; effective size Mdn [IQR] = 10.4 [11.4-7.9]). CONCLUSIONS: Cross-sector alignment may strengthen local capacity for comprehensive SUD care for pregnant and parenting women. Healthcare organizations are key players in cross-sector partnerships in the rural community, where one healthcare facility holds the central brokerage role. In contrast, public health agencies are key to cross-sector collaboration with social services in the urban community.

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.

The effect of rural hospital closures on maternal and infant health.

OBJECTIVE: To evaluate the effect of rural hospital closures on infant and maternal health outcomes. DATA SOURCES AND STUDY SETTING: We used restricted National Vital Statistics System birth and linked birth and infant death data, merged with county-level hospital closures from the Sheps Center for the period 2005-2019. STUDY DESIGN: We used difference-in-difference and event study methods, employing new estimators that account for staggered treatment timing. Our key outcome variables were prenatal care initiation; birth outcomes (<2500 g; <1500 g; <37 weeks; <28 weeks; 5-min Apgar); delivery outcomes (cesarean, induction, hospital birth); and infant death (<1 year of birth; <=30 days of birth; <=7 days of birth; <= 1 day after birth). DATA COLLECTION/EXTRACTION METHODS: The analysis covered all births in the United States in rural counties (by rurality: all, most, moderately rural). PRINCIPAL FINDINGS: We found evidence that fewer individuals delivered in their county of residence after a hospital closure, and this was most pronounced for residents of the most rural counties (29%-52% decline (p < 0.01) in the likelihood of delivering in their residence county). We found that hospital closures worsen prenatal, infant, and delivery outcomes for residents of moderately rural counties but improve those outcomes for those in the most rural counties. In moderately rural counties, low birth weight births increased by 10.4% (p < 0.01). We found suggestive evidence of decreased infant deaths in the most rural counties. This pattern of findings is consistent with closures leading residents of the most rural counties to seek care in a different county and residents of moderately rural counties to seek care at a different hospital in the same county. CONCLUSIONS: Loss of hospital care has meaningful effects on the rural populations; investigating rural counties in aggregate may miss nuanced differences in the effects on the margin of rurality.

The impact of access to prenatal health insurance for noncitizen women on child health.

OBJECTIVE: To estimate the effects of prenatal public health insurance targeting noncitizens on the health of U.S.-born children of noncitizen mothers beyond birth outcomes. DATA SOURCES AND STUDY SETTING: This paper uses the restricted version of the 1998-2014 National Health Interview Survey with state-level geographic identifiers. STUDY DESIGN: The empirical strategy compares outcomes in states that adopted the Children's Health Insurance Plan (CHIP) Unborn Child Option with states that never adopted or adopted it at different times, controlling for differences in the pre-treatment period. I use a flexible event-study analysis to quantify the effects of the Unborn Child Option on noncitizen women's health insurance coverage, health care utilization, and their children's health. DATA COLLECTION/EXTRACTION METHODS: All data are derived from pre-existing sources. PRINCIPAL FINDINGS: The study finds that the impact of the Unborn Child Option is a 4.7%-point increase in public health insurance coverage (p < 0.01) and 0.48 more doctor's office visits (p < 0.1) annually among noncitizens of childbearing ages. Subsequently, the reform leads to a 7%-point rise in the rate of parents reporting their 4-6-year-old children are in "excellent" or "very good" health (p < 0.01). While no improvements are evident at birth and at younger ages, observed health improvements begin to appear by preschool age. CONCLUSIONS: The study contributes to the literature by providing evidence that certain benefits of in-utero public health insurance targeting noncitizens may appear several years after birth, specifically around preschool age.

Racial disparities in pregnancy options counseling and referral in the US South.

OBJECTIVE: The objective of this study is to examine racial variation in receipt of counseling and referral for pregnancy options (abortion, adoption, and parenting) following pregnancy confirmation. Equitable offering of such information is a professional and ethical obligation and an opportunity to prevent racial disparities in maternal and child health. DATA SOURCE: Primary data from patients at southern United States publicly funded family planning clinics, October 2018-June 2019. STUDY DESIGN: Patients at 14 clinics completed a survey about their experiences with pregnancy options counseling and referral following a positive pregnancy test. The primary predictor variable was patients' self-reported racial identity. Outcomes included discussion of pregnancy options, referral for those options, and for support services. DATA COLLECTION: Data from eligible patients with non-missing information for key variables (n = 313) were analyzed using descriptive statistics, χ2 tests, and multivariable logistic regression. PRINCIPAL FINDINGS: Patients were largely Black (58%), uninsured (64%), and 18-29 years of age (80%). Intention to continue pregnancy and receipt of prenatal care referral did not differ significantly among Black as compared to non-Black patients. However, Black patients had a higher likelihood of wanting an abortion or adoption referral and not receiving one (abortion: marginal effect [ME] = 7.68%, p = 0.037; adjusted ME [aME] = 9.02%, p = 0.015; adoption: ME = 7.06%, p = 0.031; aME = 8.42%, p = 0.011). Black patients intending to end their pregnancies had a lower probability of receiving an abortion referral than non-Black patients (ME = -22.37%, p = 0.004; aME = -19.69%, p = 0.023). In the fully adjusted model, Black patients also had a higher probability of wanting access to care resources (including transportation, childcare, and financial support) and not receiving them (aME = 5.38%, p = 0.019). CONCLUSIONS: Clinical interactions surrounding pregnancy confirmation provide critical opportunities to discuss options, coordinate care, and mitigate risk, yet are susceptible to systemic bias. These findings add to limited evidence around pregnancy counseling and referral disparities. Ongoing assessment of pregnancy counseling and referral disparities can provide insight into organizational strengths or the potential to increase structural equity.

Changes in prenatal care and birth outcomes after federally qualified health center expansion.

OBJECTIVE: To evaluate whether the expansion of Federally Qualified Health Centers (FQHCs) improved late prenatal care initiation, low birth weight, and preterm birth among Medicaid-covered or uninsured individuals. DATA SOURCES AND STUDY SETTING: We identified all FQHCs in California using the Health Resources and Services Administration's Uniform Data System from 2000 to 2019. We used data from the U.S. Census American Community Survey to describe area characteristics. We measured outcomes in California birth certificate data from 2007 to 2019. STUDY DESIGN: We compared areas that received their first FQHC between 2011 and 2016 to areas that received it later or that had never had an FQHC. Specifically, we used a synthetic control with a staggered adoption approach to calculate non-parametric estimates of the average treatment effects on the treated areas. The key outcome variables were the rate of Medicaid or uninsured births with late prenatal care initiation (>3 months' gestation), with low birth weight (<2500 grams), or with preterm birth (<37 weeks' gestation). DATA COLLECTION/EXTRACTION METHODS: The analysis was limited to births covered by Medicaid or that were uninsured, as indicated on the birth certificate. PRINCIPAL FINDINGS: The 55 areas in California that received their first FQHC in 2011-2016 were more populous; their residents were more likely to be covered by Medicaid, to be low-income, or to be Hispanic than residents of the 48 areas that did not have an FQHC by the end of the study period. We found no statistically significant impact of the first FQHC on rates of late prenatal care initiation (ATT: -10.4 [95% CI -38.1, 15.0]), low birth weight (ATT: 0.2 [95% CI -7.1, 5.4]), or preterm birth (ATT: -7.0 [95% CI -15.5, 2.3]). CONCLUSIONS: Our results from California suggest that access to primary and prenatal care may not be enough to improve these outcomes. Future work should evaluate the impact of ongoing initiatives to increase access to maternal health care at FQHCs through targeted workforce investments.

Group Prenatal Care and Emergency Room Utilization.

Pregnancy-related complaints are a significant driver of emergency room (ER) utilization among women. Because of additional time for patient education and provider relationships, group prenatal care may reduce ER visits among pregnant women by helping them identify appropriate care settings, improving understanding of common pregnancy discomforts, and reducing risky health behaviors. We conducted a retrospective cohort study, utilizing Medicaid claims and birth certificate data from a statewide expansion of group care, to compare ER utilization between pregnant women participating in group prenatal care and individual prenatal care. Using propensity score matching methods, we found that group care was associated with a significant reduction in the likelihood of having any ER utilization (-5.9% among women receiving any group care and -6.0% among women attending at least five group care sessions). These findings suggest that group care may reduce ER utilization among pregnant women and encourage appropriate health care utilization during pregnancy.

Medicaid expansions, preconception insurance, and unintended pregnancy among new parents.

OBJECTIVE: To assess the relationship between recent changes in Medicaid eligibility and preconception insurance coverage, pregnancy intention, health care use, and risk factors for poor birth outcomes among first-time parents. DATA SOURCE: This study used individual-level data from the national Pregnancy Risk Assessment Monitoring System (2006-2017), which surveys individuals who recently gave birth in the United States on their experiences before, during, and after pregnancy. STUDY DESIGN: Outcomes included preconception insurance status, pregnancy intention, stress from bills, early prenatal care, and diagnoses of high blood pressure and diabetes. Outcomes were regressed on an index measuring Medicaid generosity, which captures the fraction of female-identifying individuals who would be eligible for Medicaid based on state income eligibility thresholds, in each state and year. DATA COLLECTION/EXTRACTION METHODS: The sample included all individuals aged 20-44 with a first live birth in 2009-2017. PRINCIPAL FINDINGS: Among all first-time parents, a 10-percentage point (ppt) increase in Medicaid generosity was associated with a 0.7 ppt increase (P = 0.017) in any insurance coverage and a 1.5 ppt increase (P < 0.001) in Medicaid coverage in the month before pregnancy. We also observed significant increases in insurance coverage and early prenatal care and declines in stress from bills and unintended pregnancies among individuals with a high-school degree or less. CONCLUSIONS: Increasing Medicaid generosity for childless adults has the potential to improve insurance coverage in the critical period before pregnancy and help improve maternal outcomes among first-time parents.

Choosing a hospital for obstetric, gynecologic, or reproductive healthcare: what matters most to patients?

BACKGROUND: Despite millions of U.S. women receiving obstetric/gynecologic or reproductive care in a hospital each year, little is known about which factors matter most to women in choosing a hospital for this care. OBJECTIVE(S): To describe women's reasons for choosing their hospital for obstetric/gynecologic or reproductive care, and to examine characteristics associated with reporting specific factors as important in hospital choice. MATERIALS AND METHODS: We conducted a nationally representative, cross-sectional survey of women aged 18-45 years. The 2016 survey recruited women from AmeriSpeak, a probability-based research panel. A total of 1430 women completed the survey. All data analysis used weighting and accounted for the complex survey design. We conducted bivariate and multinomial logistic regression modeling to assess associations. RESULTS: Three-fourths of women cited a hospital's overall reputation/quality as a reason, and one-third named this as the most important reason for choosing a hospital. A total of 14% reported hospital religious affiliation as a reason. Compared to those with no prior deliveries, women who had delivered an infant were more likely to report that their top reason was specialty services/provider (relative risk ratio, 2.97; 95% confidence interval, 1.96-4.52) and were also more likely to report overall hospital quality/reputation as their top reason (relative risk ratio, 1.52; 95% confidence interval, 1.06-2.17), compared to logistical reasons. Metropolitan versus non-metropolitan residence was also a significant factor in hospital choice. CONCLUSION: Women endorse many factors when choosing a hospital for reproductive care, but perceived quality and reputation outweigh logistical concerns such as location and insurance.

The impact of the Medicaid high-risk ob care management program in New York State.

OBJECTIVES: To examine the effect of high-risk obstetrics (HROB) care management on infant health and Medicaid expenditures. DATA SOURCES/STUDY SETTING: Medicaid administrative data and vital statistics from 2011 to 2013. In New York State, all Medicaid managed care plans provide HROB care management to their members. STUDY DESIGN: We conducted a retrospective cohort study with a nonequivalent control group. Selection bias was addressed by using probit and OLS models with the Heckman correction and inverse probability weight with regression adjustment. PRINCIPAL FINDINGS: While program enrollment was associated with poor infant health outcomes (low birthweight, very low birthweight, preterm delivery, and gestational age), correcting for sample selection substantially improved most of these outcomes. All infant health outcomes significantly improved as the number of weeks in the program increased. We found that a 1-week increase in program duration is associated with a 0.01 percentage point decrease in low birthweight and a 0.03 percentage point decrease in very low birthweight. Further, a 1-week increase in program duration decreases the probability of preterm delivery by 0.01 percentage points and increases gestational age by 0.14 days. Medicaid expenditures for maternity care and newborn delivery were not significantly or materially affected by program enrollment or program duration. CONCLUSIONS: High-risk obstetrics care management appears to successfully identify individuals with high-risk pregnancies and improve health without substantially increasing medical expenses.

Does the Use of Diagnostic Technology Reduce Fetal Mortality?

OBJECTIVE: To examine the effect that the introduction of new diagnostic technology in obstetric care has had on fetal death. DATA SOURCE: The Medical Birth Registry of Norway provided detailed medical information for approximately 1.2 million deliveries from 1967 to 1995. Information about diagnostic technology was collected directly from the maternity units, using a questionnaire. STUDY DESIGN: The data were analyzed using a hospital fixed-effects regression with fetal mortality as the outcome measure. The key independent variables were the introduction of ultrasound and electronic fetal monitoring at each maternity ward. Hospital-specific trends and risk factors of the mother were included as control variables. The richness of the data allowed us to perform several robustness tests. PRINCIPAL FINDING: The introduction of ultrasound caused a significant drop in fetal mortality rate, while the introduction of electronic fetal monitoring had no effect on the rate. In the population as a whole, ultrasound contributed to a reduction in fetal deaths of nearly 20 percent. For post-term deliveries, the reduction was well over 50 percent. CONCLUSION: The introduction of ultrasound made a major contribution to the decline in fetal mortality at the end of the last century.

Shifting Patterns in Cesarean Delivery Scheduling and Timing in Oregon before and after a Statewide Hard Stop Policy.

OBJECTIVES: To assess the use and timing of scheduled cesareans and other categories of cesarean delivery and the prevalence of neonatal morbidity among cesareans in Oregon before and after the implementation of Oregon's statewide policy limiting elective early deliveries. DATA SOURCES: Oregon vital statistics records, 2008-2013. STUDY DESIGN: Retrospective cohort study, with multivariable logistic regression, regression controlling for time trends, and interrupted time series analyses, to compare the odds of different categories of cesarean delivery and the odds of neonatal morbidity pre- and postpolicy. DATA COLLECTION/EXTRACTION METHODS: We analyzed vital statistics data on all term births in Oregon (2008-2013), excluding births in 2011. PRINCIPAL FINDINGS: The odds of early-term scheduled cesareans decreased postpolicy (adjusted odds ratio [aOR], 0.70; 95 percent confidence interval [CI], 0.66-0.74). In the postpolicy period, there were mixed findings regarding assisted neonatal ventilation and neonatal intensive care unit admission, with regression models indicating higher postpolicy odds in some categories, but lower postpolicy odds after controlling for time trends. CONCLUSIONS: Oregon's hard stop policy limiting elective early-term cesarean delivery was associated with lower odds of cesarean delivery in the category of women who were targeted by the policy; more research is needed on impact of such policies on neonatal outcomes.

Does Maternity Care Coordination Influence Perinatal Health Care Utilization? Evidence from North Carolina.

OBJECTIVE: To examine effects of maternity care coordination (MCC) on perinatal health care utilization among low-income women. DATA SOURCES: North Carolina Center for Health Statistics Baby Love files that include birth certificates, maternity care coordination records, WIC records, and Medicaid claims. STUDY DESIGN: Causal effects of MCC participation on health care outcomes were estimated in a sample of 7,124 singleton Medicaid-covered births using multiple linear regressions with inverse probability of treatment weighting (IPTW). PRINCIPAL FINDINGS: Maternity care coordination recipients were more likely to receive first-trimester prenatal care (p < .01) and averaged three more prenatal visits and two additional primary care visits during pregnancy; they were also more likely to participate in WIC and to receive postpartum family planning services (p < .01). Medicaid expenditures were greater among mothers receiving MCC. CONCLUSIONS: Maternity care coordination facilitates access to health care and supportive services among Medicaid-covered women. Increased maternal service utilization may increase expenditures in the short run; however, improved newborn health may reduce the need for costly neonatal care, and by implication the need for early intervention and other supports for at-risk children.

State Prescription Contraception Insurance Mandates: Effects on Unintended Births.

OBJECTIVE: To test the effects of state prescription contraception insurance mandates on unintended, mistimed, and unwanted births in a sample of privately insured recent mothers. DATA: We pooled Pregnancy Risk Assessment Monitoring System (PRAMS) data from 1997 to 2012 to study 209,964 privately insured recent mothers in 24 states, 11 of which implemented prescription contraception coverage mandates between 2000 and 2008. STUDY DESIGN: Individual-level difference-in-differences models compare the probability of unintended birth among privately insured recent mothers in state-years with mandates to those in state-years without mandates. Additional models use aggregate data to estimate the effect of mandates on states' number of unintended births. PRINCIPAL FINDINGS: State mandates are associated with decreased probability of unintended birth (1.58 percentage points) among privately insured women in the second year of implementation, driven by decreased probability of mistimed birth (1.37 percentage points or 614 births per state-year) in the second year of implementation. We find no effects in the first year of implementation or on the probability of unwanted birth. Unexpectedly, recent mothers without private insurance experienced declines in unintended birth, but among unwanted, rather than mistimed, births. CONCLUSIONS: State prescription contraception insurance mandates are associated with reduced probability of unintended and mistimed births among privately insured women.

Potential Medicaid cost savings from maternity care based at a freestanding birth center.

OBJECTIVES: Medicaid pays for about half the births in the United States, at very high cost. Compared to usual obstetrical care, care by midwives at a birth center could reduce costs to the Medicaid program. This study draws on information from a previous study of the outcomes of birth center care to determine whether such care reduces Medicaid costs for low income women. METHODS: The study uses results from a study of maternal and infant outcomes at the Family Health and Birth Center in Washington, D.C. Costs to Medicaid are derived from birth center data and from other national sources of the cost of obstetrical care. RESULTS: We estimate that birth center care could save an average of $1,163 per birth (2008 constant dollars), or $11.6 million per 10,000 births per year. CONCLUSIONS: Medicaid is the leading payer for maternity services. As Medicaid faces continuing cost increases and budget constraints, policy makers should consider a larger role for midwives and birth centers in maternity care for low-risk Medicaid pregnant women.

Expansion of Medicaid covered smoking cessation services: maternal smoking and birth outcomes.

OBJECTIVE: To assess whether Medicaid coverage of smoking cessation services reduces maternal smoking and improves birth outcomes. METHODS: Pooled, cross-sectional data for 178,937 women with live births from 1996 to 2008, who were insured by Medicaid in 34 states plus New York City, were used to analyze self-reported smoking before pregnancy (3 months), smoking during the last 3 months of pregnancy, smoking after delivery (3-4 months), infant birth weight, and gestational age at delivery. Maternal socio-demographic and behavior variables from survey data and birth outcomes from vital records were merged with annual state data on Medicaid coverage for nicotine replacement therapies (NRT), medications and cessation counseling. Probit and OLS regression models were used to test for effects of states' Medicaid cessation coverage on mother's smoking and infant outcomes relative to mothers in states without coverage. RESULTS: Medicaid coverage of NRT and medications is associated with 1.6 percentage point reduction (p<.05) in smoking before pregnancy among Medicaid insured women relative to no coverage. Adding counseling coverage to NRT and medication coverage is associated with a 2.5 percentage point reduction in smoking before pregnancy (p<.10). Medicaid cessation coverage during pregnancy was associated with a small increase (<1 day) in infant gestation (p<.05). CONCLUSIONS: In this sample, Medicaid coverage of smoking cessation only affected women enrolled prior to pregnancy. Expansions of Medicaid eligibility to include more women prior to pregnancy in participating states, and mandated coverage of some cessation services without co-pays under the Affordable Care Act (ACA) should reduce the number of women smoking before pregnancy.
