Lifetime Upward Economic Mobility and US-Born Latina Women's Preterm Birth Rates.

OBJECTIVES: To determine whether Latina women's upward economic mobility from early-life residence in impoverished urban neighborhoods is associated with preterm birth (< 37 weeks, PTB) . METHODS: Multivariate logistic regression analyses were performed on the Illinois transgenerational birth-file with appended US census income information for Hispanic infants (born 1989-1991) and their mothers (born 1956-1976). RESULTS: In Chicago, modestly impoverished-born Latina women (n = 1,674) who experienced upward economic mobility had a PTB rate of 8.5% versus 13.1% for those (n = 3,760) with a lifelong residence in modestly impoverished neighborhoods; the unadjusted and adjusted (controlling for age, marital status, adequacy of prenatal care, and cigarette smoking) RR equaled 0.65 (0.47, 0.90) and 0.66 (0.47, 0.93), respectively. Extremely impoverished-born Latina women (n = 2,507) who experienced upward economic mobility across their life-course had a PTB rate of 12.7% versus 15.9% for those (n = 3,849) who had a lifelong residence in extremely impoverished neighborhoods, the unadjusted and adjusted RR equaled 0.8 (0.63. 1.01) and 0.95 (0.75, 1.22), respectively. CONCLUSIONS FOR PRACTICE: Latina women's upward economic mobility from early-life residence in modestly impoverished urban neighborhoods is associated with a decreased risk of PTB. A similar trend is absent among their peers with an early-life residence in extremely impoverished areas.

Women's Economic Mobility and Small for Gestational Age Rates: The Effect of Paternal Early-Life Socioeconomic Position.

OBJECTIVE: To determine whether paternal early-life socioeconomic position (defined by neighborhood income) modifies the association of maternal economic mobility and infant small for gestational age (weight for gestational age < 10th percentile, SGA) rates. METHODS: Stratified and multilevel binomial regression analyses were executed on the Illinois transgenerational dataset of parents (born 1956-1976) and their infants (born 1989-1991) with appended U.S. census income information. Only Chicago-born women with an early-life residence in impoverished or affluent neighborhoods were studied. RESULTS: The incidence of impoverished-born women's upward economic mobility among births (n = 3777) with early-life low socioeconomic position (SEP) fathers was less than that of those (n = 576) with early-life high SEP fathers: 56% vs 71%, respectively, p < 0.01. The incidence of affluent-born women's downward economic mobility among births (n = 2370) with early-life low SEP fathers exceeded that of those (n = 3822) with early-life high SEP fathers: 79% vs 66%, respectively, p < 0.01. The adjusted RR of infant SGA for maternal upward (compared to lifelong impoverishment) economic mobility among fathers with early-life low and high SEP equaled 0.68 (0.56, 0.82) and 0.81 (0.47, 1.42), respectively. The adjusted RR of infant SGA for maternal downward (compared to lifelong residence in affluent neighborhoods) economic mobility among fathers with early-life low and high SEP were 1.37 (0.91, 2.05) and 1.17 (0.86, 1.59), respectively. CONCLUSIONS: Paternal early-life SEP is associated with maternal economic mobility (both upward and downward); however, it does not modify the relationship between maternal economic mobility and infant SGA rates.

Comparing Postpartum Care Utilization from Medicaid Claims and the Pregnancy Risk Assessment Monitoring System in Wisconsin, 2011-2015.

OBJECTIVE: To compare two data sources from Wisconsin-Medicaid claims and Pregnancy Risk Assessment Monitoring System (PRAMS) surveys-for measuring postpartum care utilization and to better understand the incongruence between the sources. METHODS: We used linked Medicaid claims and PRAMS surveys of Wisconsin residents who delivered a live birth during 2011-2015 to assess women's postpartum care utilization. Three different definitions of postpartum care from Medicaid claims were employed to better examine bundled service codes and timing of care. We used one question from the PRAMS survey that asks women if they have had a postpartum checkup. Concordance between the two data sources was examined using Cohen's Kappa value. For women who reported having a postpartum checkup on PRAMS but did not have a Medicaid claim for a traditional postpartum visit, we determined the other types of health care visits these women had after delivery documented in the Medicaid claims. RESULTS: Among the 2313 women with a Medicaid-paid delivery and who completed a PRAMS survey, 86.6% had claims for a postpartum visit during the first 12 weeks postpartum and 90.5% self-reported a postpartum checkup on PRAMS (percent agreement = 79.9%, Kappa = 0.015). The percent agreement and Kappa values varied based on the definition of postpartum care derived from the Medicaid claims data. CONCLUSIONS: There was slight agreement between Medicaid claims and PRAMS data. Most women had Medicaid claims for postpartum care at some point in the first 12 weeks postpartum, although the timing of these visits was somewhat unclear due to the use of bundled service codes.

The Effect of Continuous Versus Pregnancy-Only Medicaid Eligibility on Routine Postpartum Care in Wisconsin, 2011-2015.

OBJECTIVE: To compare patterns of routine postpartum health care utilization for women in Wisconsin with continuous Medicaid eligibility versus pregnancy-only Medicaid METHODS: This analysis used Medicaid records and linked infant birth certificates for Medicaid paid births in Wisconsin during 2011-2015 (n = 105,718). We determined if women had continuous or pregnancy-only eligibility from the Medicaid eligibility file. We used a standard list of billing codes to identify if women received routine postpartum care. We examined maternal characteristics and receipt of postpartum care overall and by Medicaid eligibility category. Finally, we used a binomial model to calculate the relationship between Medicaid eligibility category and receipt of postpartum care, adjusted for maternal characteristics. RESULTS: Women with continuous Medicaid had profiles more consistent with low postpartum visit attendance rates (e.g., younger, more likely to use tobacco) than women with pregnancy-only Medicaid. However, after adjusting for maternal characteristics, women with continuous Medicaid eligibility had a postpartum visit rate that was 6 percentage points higher than the rate for women with pregnancy-only Medicaid (RD: 6.27, 95% CI 5.72, 6.82). CONCLUSIONS FOR PRACTICE: Women with pregnancy-only Medicaid were less likely to have received routine postpartum care than women with continuous Medicaid. Medicaid coverage beyond the current guaranteed 60 days postpartum could help provide more women access to postpartum care.

Excess Early (< 34 weeks) Preterm Rates Among Non-acknowledged and Acknowledged Low Socioeconomic Position Fathers: The Role of Women's Selected Pregnancy-Related Risk Factors.

OBJECTIVE: To determine the proportion of the excess early preterm birth (< 34 weeks, PTB) rates among non-acknowledged and acknowledged low socioeconomic position (SEP) fathers attributable to White and African-American women's selected pregnancy-related risk factors for PTB. METHODS: Oaxaca-Blinder decomposition methods were performed on the Illinois transgenerational birth-file of infants (1989-1991) and their parents (1956-1976) with appended U.S. census income information. The neighborhood income of father's place of residence at the time of his birth and at the time of his infant's birth were used to measure lifetime SEP. RESULTS: Among non-Latina White women, the early PTB rate for non-acknowledged (n = 3260), acknowledged low SEP (n = 1430), and acknowledged high SEP (n = 9141) fathers equaled 4.02%, 1.82%, and 1.19, respectively; p < 0.001. White women's selected pregnancy-related risk factors for PTB (inadequate prenatal usage, suboptimal weight gain, and/or cigarette smoking) were responsible for 19.3% and 41.2% of the explained disparities in early PTB rates for non-acknowledged and acknowledged low (compared to acknowledged high) SEP fathers, respectively. Among African-American women, the early PTB rate for non-acknowledged (n = 22,727), acknowledged low SEP (n = 4426), and acknowledged high SEP (n = 365) fathers equaled 6.72%, 4.34%, and 3.29%, respectively; p < 0.001. African-American women's selected pregnancy-related risk factors for PTB were responsible for 21.4% and 20.2% of the explained disparities in early PTB rates for non-acknowledged and acknowledged low SEP fathers, respectively. CONCLUSIONS: Non-Latina White and African-American women's selected pregnancy-related risk factors for PTB explain a significant percentage of excess early PTB rates among non-acknowledged and acknowledged low (compared to acknowledged high) SEP fathers.

Early and Late Preterm Birth Rates Among US-Born Urban Women: The Effect of Men's Lifelong Class Status.

OBJECTIVE: To ascertain the relation of men's lifelong class status (as measured by neighborhood income) to the rates of early (< 34 weeks) and late (34-36 weeks) preterm birth (PTB). METHODS: Stratified and multilevel, multivariable binomial regression analyses were computed on the Illinois transgenerational birth-file of infants (born 1989-1991) and their parents (born 1956-1976) with appended U.S. census income information. The median family income of men's census tract residence at two-time periods were utilized to assess lifelong class status (defined by residence in either the lower or upper half of neighborhood income distribution). RESULTS: In Cook County Illinois, the preterm rate for births (n = 8115) to men with a lifelong lower class status was twice that of births (n = 10,330) to men with a lifelong upper class status: 13% versus 6.0%, RR = 2.2 (2.0, 2.4). This differential was greatest in early PTB rates: 3.9% versus 1.4%, RR = 3.0 (2.5, 3.7). The relation of men's lifelong class status to both PTB components persisted among non-teens, married, college-educated, and non-Latina White women, respectively. The adjusted (controlling for maternal demographic characteristics) RR of early and late PTB for men with a lifelong lower (versus upper) class status were 1.4 (1.1, 1.9) and 1.2 (1.0, 1.4), respectively. The population attributable risk of early PTB for men's lifelong lower class status equaled 16%. CONCLUSIONS: Men's lifelong lower (versus upper) class status is a novel risk factor for early preterm birth regardless of maternal demographic characteristics. This intriguing finding has public health relevance.

Mortgage discrimination and preterm birth among African American women: An exploratory study.

OBJECTIVE: To examine whether mortgage discrimination, or redlining, is a risk factor for preterm birth among African American women in Chicago, and how it is related to racial residential segregation. METHODS: This was a retrospective cross-sectional study in Chicago, Illinois, 1989-1991. African American mothers (n = 33,586) in the Illinois Transgenerational Birth File were linked to the 1990 census and the 1990-1995 Home Mortgage Disclosure Act database. Logistic regression models assessed the relationship between redlining and preterm birth rates. RESULTS: Preterm birth rates were higher among African American women in redlined areas (18.5%) vs. non-redlined areas (17.1%). Unadjusted and adjusted odds ratio for preterm birth among African American women in redlined neighborhoods, compared to non-redlined neighborhoods, were 1.08 (95% CI 1.03-1.14) and 1.12 (1.04-1.20), respectively. By level of racial residential segregation, preterm birth rate was elevated (18.2%) in redlined, high-proportion African American areas compared to non-redlined high-proportion African American areas (16.7%), redlined low- (16.2%) and mid-proportion (16.1%) African American areas. CONCLUSIONS: Mortgage discrimination may be an important measure of institutional racism to be used in understanding racial disparities in preterm birth.

Persisting Gaps in Coverage and Services of Illinois Women Who Acquired Insurance After Implementation of the Affordable Care Act.

OBJECTIVES: Before implementation of the Affordable Care Act, many uninsured women in Illinois received care through safety-net programs. The new law allowed them to acquire health insurance through Medicaid or the Illinois Health Exchange. We examined (1) the health care experiences of such women who previously used a safety-net program and acquired this new coverage and (2) persisting gaps in coverage for breast and cervical cancer services and other health care services. METHODS: We interviewed a stratified random sample of 400 women aged 34-64 in Illinois each year during 2015-2017 (total N = 1200). We used multivariable logistic regression models to determine the association between health insurance status (Illinois Health Exchange vs Medicaid) and past 12-month gaps in coverage (ie, delaying care, not having a recent mammogram, having a medical cost, and having a medical cost not covered) for the 360 women who were former participants of the Illinois Breast and Cervical Cancer Program. We calculated odds ratios (ORs) and 95% confidence intervals (CIs), adjusting for race/ethnicity, age, income, and education. RESULTS: We found no significant differences by health insurance status in the prevalence of delaying preventive, chronic, or sick care; timeliness of the most recent mammogram; and having a major medical cost. However, of women who reported a major medical cost, women with health insurance through the Illinois Health Exchange had a higher prevalence of not having a cost covered than women with Medicaid (adjusted OR = 4.86; 95% CI, 1.48-16.03). CONCLUSIONS: The results of this study suggest that many women who gained health insurance lacked adequate coverage and services. Safety-net programs will likely continue to play an essential role in supporting women as they navigate a complex system.

Severe Maternal Morbidity, A Tale of 2 States Using Data for Action-Ohio and Massachusetts.

Purpose Describe how Ohio and Massachusetts explored severe maternal morbidity (SMM) data, and used these data for increasing awareness and driving practice changes to reduce maternal morbidity and mortality. Description For 2008-2013, Ohio used de-identified hospital discharge records and International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes to identify delivery hospitalizations. Massachusetts used existing linked data system infrastructure to identify delivery hospitalizations from birth certificates linked to hospital discharge records. To identify delivery hospitalizations complicated by one or more of 25 SMMs, both states applied an algorithm of ICD-9-CM diagnosis and procedure codes. Ohio calculated a 2013 SMM rate of 144 per 10,000 delivery hospitalizations; Massachusetts calculated a rate of 162. Ohio observed no increase in the SMM rate from 2008 to 2013; Massachusetts observed a 33% increase. Both identified disparities in SMM rates by maternal race, age, and insurance type. Assessment Ohio and Massachusetts engaged stakeholders, including perinatal quality collaboratives and maternal mortality review committees, to share results and raise awareness about the SMM rates and identified high-risk populations. Both states are applying findings to inform strategies for improving perinatal outcomes, such as simulation training for obstetrical emergencies, licensure rules for maternity units, and a focus on health equity. Conclusion Despite data access differences, examination of SMM data informed public health practice in both states. Ohio and Massachusetts maximized available state data for SMM investigation, which other states might similarly use to understand trends, identify high risk populations, and suggest clinical or population level interventions to improve maternal morbidity and mortality.

Application of an Implementation Science Framework to Policies on Immediate Postpartum Long-Acting Reversible Contraception.

OBJECTIVES: Implementation science provides useful tools for guiding and evaluating the integration of evidence-based interventions with standard practice. The objective of our study was to demonstrate the usefulness of applying an implementation science framework-the Consolidated Framework for Implementation Research (CFIR)-to increase understanding of implementation of complex statewide public health initiatives, using the example of Medicaid immediate postpartum long-acting reversible contraception (LARC) policies. METHODS: We conducted semistructured telephone interviews with the 13 state teams participating in the Immediate Postpartum LARC Learning Community. We asked teams to describe the implementation facilitators, barriers, and strategies in 8 focus areas of the Learning Community. We audio-recorded and transcribed interviews and then coded each interview according to the domains and constructs (ie, theoretical concepts) of the CFIR. RESULTS: Cosmopolitanism (ie, networking with external organizations) was the most frequently coded construct of the framework. A related construct was networks and communications (ie, the nature and quality of social networks and formal and informal communications in an organization). Within the construct of cost, state teams identified barriers that were often unable to be overcome. Trialability (ie, ability to test the intervention on a small scale) and engaging champions (ie, attracting and involving persons who dedicate themselves to supporting the intervention in an organization) were among the most salient constructs of the framework and were the sources of many implementation strategies. CONCLUSIONS: State leaders and program staff members may benefit from considering the CFIR domains and constructs in the planning, implementation, and evaluation of complex statewide public health initiatives.

Low Birth Weight Among Infants Born to Black Latina Women in the United States.

Objectives To explore associations between race, nativity, and low birth weight (LBW) among Latina and non-Latina women, with special attention to the Black Latina subgroup. Methods Using US natality data from 2011 to 2013, we designed a population-based study to compare LBW (< 2500 g) rates across six groups of women with self-identified race (N = 7,865,264)-White and Black Latina, foreign-born and US-born; non-Latina Black; and non-Latina White-creating 4 models for analysis: unadjusted (Model 1) and adjusted for sociodemographic factors (Model 2), sociodemographic plus medical risk factors (Model 3), and Model 3 factors plus smoking (Model 4). Results Infant LBW rate for Black Latinas (7.9%) was higher than White Latinas (5.6%) and varied by nativity: US-born (8.9%) versus foreign-born (6.1%). Among all study groups, US-born Black Latinas' LBW rate (8.9%) was second only to non-Latina Blacks (11.0%). In unadjusted Model 1, US-born Black Latinas had 81% (odds ratio [OR]: 1.81; 95% confidence interval [CI]: 1.74-1.88) and foreign-born Black Latinas had 22% (OR: 1.22; 95% CI 1.15-1.29) higher odds of LBW than non-Latina White women (reference group). However, in Model 2, ORs for foreign-born Black Latinas were nearly identical to non-Latina Whites (OR: 1.03; 95% CI 0.97-1.1), while US-born Black Latinas' odds were still 47% higher (OR: 1.47; 95% CI 1.42-1.53). Model 3 ORs for each group were similar to Model 2. Conclusions for Practice A significant subgroup of Latina women self-identify as Black, and their LBW rates are higher than White Latinas. Black Latinas born in the United States fare worse than their foreign-born counterparts, implicating negative effects of Black race specific to the US context.

State-Identified Implementation Strategies to Increase Uptake of Immediate Postpartum Long-Acting Reversible Contraception Policies.

BACKGROUND: In 2014, the Association of State and Territorial Health Officials (ASTHO) convened a multistate Immediate Postpartum Long-Acting Reversible Contraception (LARC) Learning Community to facilitate cross-state collaboration in implementation of policies. The Learning Community model was based on systems change, through multistate peer-to-peer learning and strategy-sharing activities. This study uses interview data from 13 participating state teams to identify state-implemented strategies within defined domains that support policy implementation. MATERIALS AND METHODS: Semistructured interviews were conducted by the ASTHO team with state team members participating in the Learning Community. Interviews were transcribed and implementation strategies were coded. Using qualitative analysis, the state-reported domains with the most strategies were identified. RESULTS: The five leading domains included the following: stakeholder partnerships; provider training; outreach; payment streams/reimbursement; and data, monitoring and evaluation. Stakeholder partnership was identified as a cross-cutting domain. Every state team used strategies for stakeholder partnerships and provider training, 12 reported planning or engaging in outreach efforts, 11 addressed provider and facility reimbursement, and 10 implemented data evaluation strategies. All states leveraged partnerships to support information sharing, identify provider champions, and pilot immediate postpartum LARC programs in select delivery facilities. CONCLUSIONS: Implementing immediate postpartum LARC policies in states involves leveraging partnerships to develop and implement strategies. Identifying champions, piloting programs, and collecting facility-level evaluation data are scalable activities that may strengthen state efforts to improve access to immediate postpartum LARC, a public health service for preventing short interbirth intervals and unintended pregnancy among postpartum women.

Affluent-Born White Mother's Descending Neighborhood Income and Infant Mortality: A Population-Based Study.

Objectives To determine whether affluent-born White mother's descending neighborhood income is associated with infant mortality rates (< 365 day, IMR). Methods Stratified and multilevel logistic regression analyses were completed on the Illinois transgenerational dataset of singleton births (1989-1991) to non-Latina White mothers (1956-1976) with an early-life residence in affluent neighborhoods (defined as the fourth quartile of income distribution). The breadth of descending neighborhood income was defined by mother's neighborhood income at the time of delivery. Results Infants of White mothers (n = 4890) who did not suffer descending neighborhood income by the time of delivery had a first-year mortality rate of 5.1/1,000. Infants of White mothers who experienced minor (n = 5112), modest (n = 2158), or extreme (n = 339) descending neighborhood income had IMR of 6.5/1,000, 14.4/1,000, and 11.8/1,000, respectively; RR [95% CI] = 1.3 [0.8, 2.1], 2.8 [1.7, 4.8], and 2.3 [0.8, 6.6], respectively. The incidence of young maternal age, inadequate prenatal care utilization, and cigarette smoking rose as descending neighborhood income increased, p < 0.01. In multilevel logistic regression models, the adjusted (controlling for selected individual-level co-variates) OR [95% CI] of infant mortality for White women with an early-life residence in affluent neighborhoods who subsequently experienced minor or modest to extreme (versus absent) descending neighborhood income equaled 1.0 [0.6, 1.8] and 2.1 [1.1, 3.8] respectively. Conclusions White mother's modest to extreme descending neighborhood income from early-life residence in affluent neighborhoods is associated with a twofold greater risk of infant mortality independent of selected biologic, medical, and behavioral characteristics.

Policy change is not enough: engaging provider champions on immediate postpartum contraception.

Rates of short-interval pregnancies that result in unintended pregnancies remain high in the United States and contribute to adverse reproductive health outcomes. Long-acting reversible contraception methods have annual failure rates of <1%, compared with 9% for oral contraceptive pills, and are an effective strategy to reduce unintended pregnancies. To increase access to long-acting reversible contraception in the immediate postpartum period, several State Medicaid programs, which include those in Iowa and Louisiana, recently established reimbursement policies to remove the barriers to reimbursement of immediate postpartum long-acting reversible contraception insertion. We used a mixed-methods approach to analyze 2013-2015 linked Medicaid and vital records data from both Iowa and Louisiana and to describe trends in immediate postpartum long-acting reversible contraception provision 1 year before and after the Medicaid reimbursement policy change. We also used data from key informant interviews with state program staff to understand how provider champions affected policy uptake. We found that the monthly average for the number of insertions in Iowa increased from 4.6 per month before the policy to 6.6 per month after the policy; in Louisiana, the average number of insertions increased from 2.6 per month before the policy to 45.2 per month. In both states, the majority of insertions occurred at 1 academic/teaching hospital. In Louisiana, the additional increase may be due to the engagement of a provider champion who worked at both the state and facility level. Recruiting, training, engaging, and supporting provider champions, as facilitators, with influence at state and facility levels, is an important component of a multipart strategy for increasing successful implementation of state-level Medicaid payment reform policies that allow reimbursement for immediate postpartum long-acting reversible contraception insertions.

African-American women's Upward Economic Mobility and Small for Gestational Age Births: A Population-Based Study.

Background The relationship between African-American women's upward economic mobility and small for gestational age (weight for gestational < 10th percentile, SGA) rates is incompletely understood. Objective To ascertain the extent to which African-American women's upward economic mobility from early-life impoverishment is coupled with reduced SGA rates. Methods Stratified and multilevel logistic regression analyses were completed on the Illinois transgenerational dataset of African-American infants (1989-1991) and their Chicago-born mothers (1956-1976) with linked U.S. census income information. Results Impoverished-born (defined as lowest quartile of neighborhood income distribution) African-American women (n = 4891) who remained impoverished by the time of delivery had a SGA rate of 19.7%. Individuals who achieved low (n = 5827), modest (n = 2254), or high (n = 732) upward economic mobility by adulthood had lower SGA rates of 17.2, 14.8, and 13.7%, respectively; RR = 0.9 (0.8-0.9), 0.8 (0.7-0.8), and 0.7 (0.6-0.8), respectively. In adjusted (controlling for traditional individual-level risk factors) multilevel regression models, there was a decreasing linear trend in SGA rates with increasing levels of upward economic mobility; the adjusted RR of SGA birth for impoverished-born African-American women who experienced low, modest, of high (compared to no) upward mobility equaled 0.95 (0.91, 0.99), 0.90 (0.83, 0.98), and 0.86 (0.75, 0.98), respectively, p < 0.05. Conclusions African-American women's upward economic mobility from early-life residence in poor urban communities is associated with lower SGA rates independent of adulthood risk status.

Early Preterm Birth Across Generations Among Whites and African-Americans: A Population-Based Study.

Objectives To determine the extent to which non-Latina White and African-American mother's gestational age is associated with extremely early (<30 weeks), modestly early (30-33 weeks), and late (34-36 weeks) infant preterm birth (PTB) rates. Methods Race-specific stratified and multivariable logistic regression analyses were performed on the Illinois Transgenerational Birth File of non-Latino White and African-American infants (born 1989-1991) and their mothers (born 1956-1976). Results White mothers (n = 184) born at <30 weeks had a greater extremely early infant PTB rate than White mothers (n = 131,980) born at term: 1.6 versus 0.5%, respectively; RR = 3.6 (1.2, 11.0). African-American mothers (n = 269) born at <30 weeks had a greater extremely early infant PTB rate than African-American mothers (n = 34,885) born at term: 4.1 versus 2.1%, respectively; RR = 2.0 (1.1, 3.6). In logistic regression models the adjusted (controlling for maternal age, education, parity, prenatal care, marital status, and cigarette smoking) OR of extremely early PTB for White and African-American mothers born <30 (compared to ≥37) weeks equaled 4.0 (1.2, 12.6) and 2.3 (1.2, 4.3), respectively. The adjusted OR of modestly early PTB for White and African-American mothers born 30-33 (compared to ≥37) weeks equaled 1.6 (1.0, 2.5) and 1.3 (0.9, 1.7), respectively. The adjusted OR of late PTB for White and African-American mothers born 34-36 (compared to ≥37) weeks equaled 1.2 (1.0, 1.3) and 1.1 (1.0, 1.2), respectively. Conclusions A generational association of extremely early, but not modestly early or late, PTB exists among non-Latino Whites and African-Americans.

Cesarean Outcomes in US Birth Centers and Collaborating Hospitals: A Cohort Comparison.

INTRODUCTION: High rates of cesarean birth are a significant health care quality issue, and birth centers have shown potential to reduce rates of cesarean birth. Measuring this potential is complicated by lack of randomized trials and limited observational comparisons. Cesarean rates vary by provider type, setting, and clinical and nonclinical characteristics of women, but our understanding of these dynamics is incomplete. METHODS: We sought to isolate labor setting from other risk factors in order to assess the effect of birth centers on the odds of cesarean birth. We generated low-risk cohorts admitted in labor to hospitals (n = 2527) and birth centers (n = 8776) using secondary data obtained from the American Association of Birth Centers (AABC). All women received prenatal care in the birth center and midwifery care in labor, but some chose hospital admission for labor. Analysis was intent to treat according to site of admission in spontaneous labor. We used propensity score adjustment and multivariable logistic regression to control for cohort differences and measured effect sizes associated with setting. RESULTS: There was a 37% (adjusted odds ratio [OR], 0.63; 95% confidence interval [CI], 0.50-0.79) to 38% (adjusted OR, 0.62; 95% CI, 0.49-0.79) decreased odds of cesarean in the birth center cohort and a remarkably low overall cesarean rate of less than 5% in both cohorts. DISCUSSION: These findings suggest that low rates of cesarean in birth centers are not attributable to labor setting alone. The entire birth center care model, including prenatal preparation and relationship-based midwifery care, should be studied, promoted, and implemented by policy makers interested in achieving appropriate cesarean rates in the United States.

Importance of Performance Measurement and MCH Epidemiology Leadership to Quality Improvement Initiatives at the National, State and Local Levels.

Purpose In recognition of the importance of performance measurement and MCH epidemiology leadership to quality improvement (QI) efforts, a plenary session dedicated to this topic was presented at the 2014 CityMatCH Leadership and MCH Epidemiology Conference. This paper summarizes the session and provides two applications of performance measurement to QI in MCH. Description Performance measures addressing processes of care are ubiquitous in the current health system landscape and the MCH community is increasingly applying QI processes, such as Plan-Do-Study-Act (PDSA) cycles, to improve the effectiveness and efficiency of systems impacting MCH populations. QI is maximally effective when well-defined performance measures are used to monitor change. Assessment MCH epidemiologists provide leadership to QI initiatives by identifying population-based outcomes that would benefit from QI, defining and implementing performance measures, assessing and improving data quality and timeliness, reporting variability in measures throughout PDSA cycles, evaluating QI initiative impact, and translating findings to stakeholders. MCH epidemiologists can also ensure that QI initiatives are aligned with MCH priorities at the local, state and federal levels. Two examples of this work, one highlighting use of a contraceptive service performance measure and another describing QI for peripartum hemorrhage prevention, demonstrate MCH epidemiologists' contributions throughout. Challenges remain in applying QI to complex community and systems-level interventions, including those aimed at improving access to quality care. Conclusion MCH epidemiologists provide leadership to QI initiatives by ensuring they are data-informed and supportive of a common MCH agenda, thereby optimizing the potential to improve MCH outcomes.

Healthcare Utilization in the Postpartum Period Among Illinois Women with Medicaid Paid Claims for Delivery, 2009-2010.

Purpose Postpartum care can provide the critical link between pregnancy and well-woman healthcare, improving women's health during the interconception period and beyond. However, little is known about current utilization patterns. This study describes the patterns of postpartum care experienced by Illinois women with Medicaid-paid deliveries. Methods Medicaid claims for women delivering infants in Illinois in 2009-2010 were analyzed for the receipt, timing and patterns of postpartum care, as identified through International Classification of Diseases Revision 9-Clinical Modification and Current Procedural Terminology© codes for routine postpartum care (43.4 % of visits), other postpartum services (e.g., depression screening, family planning), and other office visits for non-acute care. Results Over 90,000 visits to 55,577 women were identified, with 81.1 % of women experiencing any care during the first 90 days postpartum. Approximately 40 % had one visit, while 31 and 29 % had two and three or more visits, respectively. Thirty-four percent had their first visit <21 days postpartum, while 56 % had the first visit between 21 and 56 days postpartum. Compared with non-Hispanic whites, African-Americans had lower rates of receiving any care (73.6 vs. 86.5 %), fewer visits (48.0 vs. 33.5 % with only one visit), and later first visits (13.6 vs. 7.3 %, >56 days). Conclusions for Practice The vast majority of Illinois women with Medicaid-paid deliveries interact with the healthcare system during the first 3 months postpartum, though not always for a routine postpartum visit. Strategies to optimize postpartum health should encourage a higher level of coordination among services and linkage to well-woman care to improve subsequent women and infants' health outcomes.

Application of Implementation Science Methodology to Immediate Postpartum Long-Acting Reversible Contraception Policy Roll-Out Across States.

Purpose Providing long-acting reversible contraception (LARC) in the immediate postpartum period is an evidence-based strategy for expanding women's access to highly effective contraception and for reducing unintended and rapid repeat pregnancy. The purpose of this article is to demonstrate the application of implementation science methodology to study the complexities of rolling-out policies that promote immediate postpartum LARC use across states. Description The Immediate Postpartum LARC Learning Community, sponsored by the Association of State and Territorial Health Officials (ASTHO), is made up of multi-disciplinary, multi-agency teams from 13 early-adopting states with Medicaid reimbursement policies promoting immediate postpartum LARC. Partners include federal agencies and maternal and child health organizations. The Learning Community discussed barriers, opportunities, strategies, and promising practices at an in-person meeting. Implementation science theory and methods, including the Consolidated Framework for Implementation Research (CFIR), and a recent compilation of implementation strategies, provide useful tools for studying the complexities of implementing immediate postpartum LARC policies in birthing facilities across early adopting states. Assessment To demonstrate the utility of this framework for guiding the expansion of immediate postpartum LARC policies, illustrative examples of barriers and strategies discussed during the in-person ASTHO Learning Community meeting are organized by the five CFIR domains-intervention characteristics, outer setting, inner setting, characteristics of the individuals involved, and process. Conclusion States considering adopting policies can learn from ASTHO's Immediate Postpartum LARC Learning Community. Applying implementation science principles may lead to more effective statewide scale-up of immediate postpartum LARC and other evidence-based strategies to improve women and children's health.
