RESUMEN
Foraging behavior frequently plays a major role in driving the geographic distribution of animals. Buzzing to extract protein-rich pollen from flowers is a key foraging behavior used by bee species across at least 83 genera (these genera comprise â¼58% of all bee species). Although buzzing is widely recognized to affect the ecology and evolution of bees and flowering plants (e.g., buzz-pollinated flowers), global patterns and drivers of buzzing bee biogeography remain unexplored. Here, we investigate the global species distribution patterns within each bee family and how patterns and drivers differ with respect to buzzing bee species. We found that both distributional patterns and drivers of richness typically differed for buzzing species compared with hotspots for all bee species and when grouped by family. A major predictor of the distribution, but not species richness overall for buzzing members of four of the five major bee families included in analyses (Andrenidae, Halictidae, Colletidae, and to a lesser extent, Apidae), was the richness of poricidal flowering plant species, which depend on buzzing bees for pollination. Because poricidal plant richness was highest in areas with low wind and high aridity, we discuss how global hotspots of buzzing bee biodiversity are likely influenced by both biogeographic factors and plant host availability. Although we explored global patterns with state-level data, higher-resolution work is needed to explore local-level drivers of patterns. From a global perspective, buzz-pollinated plants clearly play a greater role in the ecology and evolution of buzzing bees than previously predicted.

BACKGROUND: Many studies reporting neonatal outcomes in birth centers include births with risk factors not acceptable for birth center care using the evidence-based CABC criteria. Accurate comparisons of outcomes by birth setting for low-risk patients are needed. METHODS: Data from the public Natality Detailed File from 2018 to 2021 were used. Logistic regression, including adjusted and unadjusted odds ratios, compared neonatal outcomes (chorioamnionitis, Apgar scores, resuscitation, intensive care, seizures, and death) between centers and hospitals. Covariates included maternal diabetes, body mass index, age, parity, and demographic characteristics. RESULTS: The sample included 8,738,711 births (8,698,432 (99.53%) in hospitals and 40,279 (0.46%) in birth centers). There were no significant differences in neonatal deaths (aOR 1.037; 95% CI [0.515, 2.088]; p-value 0.918) or seizures (aOR 0.666; 95% CI [0.315, 1.411]; p-value 0.289). Measures of morbidity either not significantly different or less likely to occur in birth centers compared to hospitals included chorioamnionitis (aOR 0.032; 95% CI [0.020, 0.052]; p-value < 0.001), Apgar score < 4 (aOR 0.814, 95% CI [0.638, 1.039], p-value 0.099), Apgar score < 7 (aOR 1.075, 95% CI [0.979, 1.180], p-value 0.130), ventilation >6 h (aOR 0.349; [0.281,0.433], p-value < 0.001), and intensive care admission (aOR 0.356; 95% CI [0.328, 0.386], p-value < 0.001). Birth centers had higher odds of assisted neonatal ventilation for <6 h as compared to hospitals (aOR 1.373; 95% CI [1.293, 1.457], p-value < 0.001). CONCLUSION: Neonatal deaths and seizures were not significantly different between freestanding birth centers and hospitals. Chorioamnionitis, Apgar scores < 4, and intensive care admission were less likely to occur in birth centers.

OBJECTIVE: To assess key birth outcomes in an alternative maternity care model, midwifery-based birth center care. DATA SOURCES: The American Association of Birth Centers Perinatal Data Registry and birth certificate files, using national data collected from 2009 to 2019. STUDY DESIGN: This observational cohort study compared key clinical birth outcomes of women at low risk for perinatal complications, comparing those who received care in the midwifery-based birth center model versus hospital-based usual care. Linear regression analysis was used to assess key clinical outcomes in the midwifery-based group as compared with hospital-based usual care. The hospital-based group was selected using nearest neighbor matching, and the primary linear regressions were weighted using propensity score weights (PSWs). The key clinical outcomes considered were cesarean delivery, low birth weight, neonatal intensive care unit admission, breastfeeding, and neonatal death. We performed sensitivity analyses using inverse probability weights and entropy balancing weights. We also assessed the remaining role of omitted variable bias using a bounding methodology. DATA COLLECTION: Women aged 16-45 with low-risk pregnancies, defined as a singleton fetus and no record of hypertension or cesarean section, were included. The sample was selected for records that overlapped in each year and state. Counties were included if there were at least 50 midwifery-based birth center births and 300 total births. After matching, the sample size of the birth center cohort was 85,842 and the hospital-based cohort was 261,439. PRINCIPAL FINDINGS: Women receiving midwifery-based birth center care experienced lower rates of cesarean section (-12.2 percentage points, p < 0.001), low birth weight (-3.2 percentage points, p < 0.001), NICU admission (-5.5 percentage points, p < 0.001), neonatal death (-0.1 percentage points, p < 0.001), and higher rates of breastfeeding (9.3 percentage points, p < 0.001). CONCLUSIONS: This analysis supports midwifery-based birth center care as a high-quality model that delivers optimal outcomes for low-risk maternal/newborn dyads.

BACKGROUND: Racial and ethnic disparities in cesarean rates in the United States are well documented. This study investigated whether cesarean inequities persist in midwife-led birth center care, including for individuals with the lowest medical risk. METHODS: National registry records of 174,230 childbearing people enrolled in care in 115 midwifery-led birth center practices between 2007 and 2022 were analyzed for primary cesarean rates and indications by race and ethnicity. The lowest medical risk subsample (n = 70,521) was analyzed for independent drivers of cesarean birth. RESULTS: Primary cesarean rates among nulliparas (15.5%) and multiparas (5.7%) were low for all enrollees. Among nulliparas in the lowest-risk subsample, non-Latinx Black (aOR = 1.37; 95% CI, 1.15-1.63), Latinx (aOR = 1.51; 95% CI, 1.32-1.73), and Asian participants (aOR = 1.48; 95% CI, 1.19-1.85) remained at higher risk for primary cesarean than White participants. Among multiparas, only Black participants experienced a higher primary cesarean risk (aOR = 1.49; 95% CI, 1.02-2.18). Intrapartum transfers from birth centers were equivalent or lower for Black (14.0%, p = 0.345) and Latinx (12.7%, p < 0.001) enrollees. Black participants experienced a higher proportion of primary cesareans attributed to non-reassuring fetal status, regardless of risk factors. Place of admission was a stronger predictor of primary cesarean than race or ethnicity. CONCLUSIONS: Place of first admission in labor was the strongest predictor of cesarean. Racism as a chronic stressor and a determinant of clinical decision-making reduces choice in birth settings and may increase cesarean rates. Research on components of birth settings that drive inequitable outcomes is warranted.
RESUMEN
Full practice authority grants non-physician providers the ability to manage patient care without physician oversight or direct collaboration. In this study, we consider whether full practice authority for certified nurse-midwives (CNMs/CMs) leads to changes in health outcomes or CNM/CM use. Using U.S. birth certificate and death certificate records over 2008-2019, we show that CNM/CM full practice authority led to little change in obstetric outcomes, maternal mortality, or neonatal mortality. Instead, full practice authority increases (reported) CNM/CM-attended deliveries by one percentage point while decreasing (reported) physician-attended births. We then explore the mechanisms behind the increase in CNM/CM-attended deliveries, demonstrating that the rise in CNM/CM-attended deliveries represents higher use of existing CNM/CMs and is not fully explainable by improved reporting of CNM/CM deliveries or changes in CNM/CM labor supply.

OBJECTIVES: Interest in expanding access to the birth center model is growing. The purpose of this research is to describe birth center staffing models and business characteristics and explore relationships to perinatal outcomes. METHODS: This descriptive analysis includes a convenience sample of all 84 birth center sites that participated in the AABC Site Survey and AABC Perinatal Data Registry between 2012 and 2020. Selected independent variables include staffing model (CNM/CM or CPM/LM), legal entity status, birth volume/year, and hours of midwifery call/week. Perinatal outcomes include rates of induction of labor, cesarean birth, exclusive breastfeeding, birthweight in pounds, low APGAR scores, and neonatal intensive care admission. RESULTS: The birth center model of care is demonstrated to be safe and effective, across a variety of staffing and business models. Outcomes for both CNM/CM and CPM/LM models of care exceed national benchmarks for perinatal quality with low induction, cesarean, NICU admission, and high rates of breastfeeding. Within the sample of medically low-risk multiparas, variations in clinical outcomes were correlated with business characteristics of the birth center, specifically annual birth volume. Increased induction of labor and cesarean birth, with decreased success breastfeeding, were present within practices characterized as high volume (>200 births/year). The research demonstrates decreased access to the birth center model of care for Black and Hispanic populations. CONCLUSIONS FOR PRACTICE: Between 2012 and 2020, 84 birth centers across the United States engaged in 90,580 episodes of perinatal care. Continued policy development is necessary to provide risk-appropriate care for populations of healthy, medically low-risk consumers.

PREMISE: Floral evolution in large clades is difficult to study not only because of the number of species involved, but also because they often are geographically widespread and include a diversity of outcrossing pollination systems. The cosmopolitan blueberry family (Ericaceae) is one such example, most notably pollinated by bees and multiple clades of nectarivorous birds. METHODS: We combined data on floral traits, pollination ecology, and geography with a comprehensive phylogeny to examine the structuring of floral diversity across pollination systems and continents. We focused on ornithophilous systems to test the hypothesis that some Old World Ericaceae were pollinated by now-extinct hummingbirds. RESULTS: Despite some support for floral differentiation at a continental scale, we found a large amount of variability within and among landmasses, due to both phylogenetic conservatism and parallel evolution. We found support for floral differentiation in anther and corolla traits across pollination systems, including among different ornithophilous systems. Corolla traits show inconclusive evidence that some Old World Ericaceae were pollinated by hummingbirds, while anther traits show stronger evidence. Some major shifts in floral traits are associated with changes in pollination system, but shifts within bee systems are likely also important. CONCLUSIONS: Studying the floral evolution of large, morphologically diverse, and widespread clades is feasible. We demonstrate that continent-specific radiations have led to widespread parallel evolution of floral morphology. We show that traits outside of the perianth may hold important clues to the ecological history of lineages.

INTRODUCTION: The Birth Center model of care is a health care delivery innovation in its fourth decade of demonstration across the United States. The purpose of this research was to evaluate the model's potential for decreasing poverty-related health disparities among childbearing families. METHODS: Between 2013 and 2017, 26,259 childbearing people received care within the 45 Center for Medicare and Medicaid Innovation Strong Start birth center sites. Secondary analysis of the prospective American Association of Birth Centers Perinatal Data Registry was conducted. Descriptive statistics described sociobehavioral, medical risk factors, and core clinical outcomes to inform the logistic regression model. Privately insured consumers were independently compared with 2 subgroups of Medicaid beneficiaries: Strong Start enrollees (midwifery-led care with peer counselors) and non-Strong Start Medicaid beneficiaries (midwifery-led care without peer counselors). RESULTS: After controlling for medical risk factors, Strong Start Medicaid beneficiaries achieved similar outcomes to privately insured consumers with no significant differences in maternal or newborn outcomes between groups. Perinatal outcomes included induction of labor (adjusted odds ratio [aOR], 0.86; 95% CI 0.61-1.13), epidural analgesia use (aOR, 1.00; 95% CI, 0.68-1.48), cesarean birth (aOR, 1.16; 95% CI, 0.87-1.53), exclusive breastfeeding on discharge (aOR, 1.11; 95% CI, 0.48-2.56), low Apgar score at 5 minutes (aOR, 1.23; 95% CI, 0.86-1.83), low birth weight (aOR, 1.12; 95% CI, 0.77-1.64), and antepartum transfer of care after the first prenatal appointment (aOR, 1.53; 95% CI, 0.97-2.40). Medicaid beneficiaries who were not enrolled in the Strong Start midwifery-led, peer counselor program demonstrated similar results except for having higher epidural analgesia use (aOR, 1.30; 95% CI, 1.10-1.53) and significantly lower exclusive breastfeeding on discharge (aOR, 0.57; 95% CI, 0.40-0.81) than their privately insured counterparts. DISCUSSION: The midwifery-led birth center model of care complemented by peer counselors demonstrated a pathway to achieve health equity.

BACKGROUND: Approximately 69% of maternal mortality occurs in the postpartum period. Contributing factors include the absence of preparation of pregnant women for the postpartum period during the antenatal period, postpartum follow-up care not being scheduled until 6 weeks after childbirth, and the lack of further care coordination. AIM: The aim of this project was to increase the frequency of effective postpartum care visits to 80% in 8 weeks at an urban obstetric clinic. METHODS: A quality improvement project was conducted through four Plan-Do-Study-Act cycles over 8 weeks. INTERVENTIONS: Postpartum Readiness & Awareness Tools (PRATs) were reviewed with patients during their late third trimester, to review postpartum warning signs that warrant further evaluation. A population health registry was created to manage early follow-up for newly postpartum patients, to ensure their recovery was progressing normally. A note template was created and implemented to guide the completion of comprehensive postpartum visits. RESULTS: Over 8 weeks, 188 patients received 1 of the 3 standardized interventions. Effective postpartum visits increased to 88%. The PRATs increased patient postpartum warning sign knowledge, with a project mean risk factor knowledge score of 6 (Goal = 5). The population health registry drove right care by ensuring early postpartum patients were recovering as expected, as seen by a project mean right-care score of 16 (Goal = 12). The note template increased the effectiveness of postpartum visits, with a mean effective postpartum care score of 10 (Goal = 10). CONCLUSIONS: The PRATs, population health registry, and note template collectively increased the quality and effectiveness of postpartum care.

Clostridium difficile causes nearly 500 000 annual infections in the USA. A total of 15 000-30 000 US deaths annually and greater than US$4.8 billion dollars are related to Clostridium difficile infection (CDI). Length of hospital stay is 2.8 -5.5 additional days and inpatient costs are estimated at US$3000-US$15 400 per episode. One major cause of CDI is misuse and overuse of antibiotics. The Centers for Disease Control and Prevention reports that 30%-50% of antibiotics prescribed in hospitals are unnecessary or inappropriate. Patients with unexplained or three or greater unformed stools in 24 hours are candidates for testing of CDI.Prior to implementation, an analysis at the local level was conducted to determine possible causes of CDI influence. Chart auditing at this urban hospital revealed that 1 out of 23 (4%) providers were treating UTIs according to hospital protocol (A. Richmond, personal communication, 6 March 2018). The standardized infection ratio in 2017, which compares the predicted to the actual infection rate, at this hospital was 1.266 for CDI. Having a solid antibiotic stewardship in place is imperative to limit antibiotic related and resistant infections. During an observational study, only one out of nine (11%) staff followed contact precaution policies at this hospital.

BACKGROUND: Progesterone has been the standard of practice for the prevention of preterm birth for decades. The drug received expedited Food and Drug Administration approval, prior to the robust demonstration of scientific efficacy. METHODS: Prospective research from the American Association of Birth Centers Perinatal Data Registry, 2007-2020. Two-tailed t tests, logistic regression, and propensity score matching were used. RESULTS: Midwifery-led care was underutilized by groups most at risk for preterm birth and was shown to be effective at maintaining low preterm birth rates. The model did not demonstrate reliable access to progesterone. People of color are most at risk of preterm birth, yet were least likely to receiving progesterone treatment. Progesterone was not demonstrated to be effective at decreasing preterm birth when comparing the childbearing people with a history of preterm birth who used the medication and those who did not within this sample. CONCLUSIONS: This study adds to the body of research that demonstrates midwifery-led care and low preterm birth rates. The ineffectiveness of progesterone in the prevention of preterm birth among people at risk was demonstrated.

BACKGROUND: Healthcare providers require data on associations between perinatal cannabis use and birth outcomes. METHODS: This observational secondary analysis come from the largest perinatal data registry in the United States related to the midwifery-led birth center model care (American Association of Birth Centers Perinatal Data Registry; N = 19 286). Births are planned across all birth settings (home, birth center, hospital); care is provided by midwives and physicians. RESULTS: Population data show that both early and persistent self-reports of cannabis use were associated with higher rates of preterm birth, low-birth-weight, lower 1-minute Apgar score, gestational weight gain, and postpartum hemorrhage. Once controlled for medical and social risk factors using logistic regression, differences for childbearing people disappeared except that the persistent use group was less likely to experience "no intrapartum complications" (adjusted odds ratio [aOR] = 0.49; 95% confidence interval [CI], 0.32-0.76; P < .01), more likely to experience an indeterminate fetal heart rate in labor (aOR = 3.218; 95% CI, 2.23-4.65; P < .05), chorioamnionitis (aOR = 2.8; 95% CI, 1.58-5.0; P < .01), low-birth-weight (aOR = 1.8; 95% CI, 1.08-3.05; P < .01), and neonatal intensive care unit (NICU) admission (aOR = 2.4; 95% CI, 1.30-4.69; P < .05). CONCLUSIONS: Well-controlled data demonstrate that self-reports of persistent cannabis use through the third trimester are associated with an increased risk of low-birth-weight and NICU admission.

INTRODUCTION: Slow or arrested progress in labor is the most frequent (64%) indication for nonemergent transfer of laboring people from freestanding birth centers to the hospital. After the 2014 publication of the Consensus Statement on Safe Prevention of Primary Cesarean Delivery (Consensus Statement), many freestanding birth centers changed their clinical practice guidelines to allow more time for active labor in the birth center prior to hospital transfer. The result of these changes has not been evaluated in birth centers. Evaluation of adoption of guidelines based on the Consensus Statement in hospitals has shown inconsistent results. METHODS: Birth centers were contacted to determine whether they changed clinical practice guidelines in response to the Consensus Statement. A before-after analysis compared outcomes for the 2 calendar years before and the 2 calendar years after adoption of new guidelines with a retrospective analysis of deidentified client-level data collected in the American Association of Birth Centers Perinatal Data Registry. RESULTS: A third of responding birth centers (11 of 33) changed their clinical practice guidelines, mostly redefining the onset of active labor as beginning at 6 cm cervical dilatation and allowing 4 hours of arrest of dilatation in active labor before transfer to the hospital. These changes were associated with fewer diagnoses of prolonged first stage of labor (13.8% vs 8.0%, P < .01) but not with fewer intrapartum transfers (14.0% vs 14.7%, P = .55) or cesarean births (5.0 vs 4.1%, P = .26.) DISCUSSION: We found no evidence that making these practice changes was associated with better outcomes. Two hours of a lack of documented cervical change in active labor is likely long enough to diagnose arrested progress in labor. Research on proportion of morbidity and mortality associated with prolonged labor could inform practice guidelines for transfers.

PURPOSE: The purpose of this study was to describe sociodemographic variations in client preference for birthplace and relationships to perinatal health outcomes. METHODS: Descriptive data analysis (raw number, percentages, and means) showed that preference for birthplace varied across racial and ethnic categories as well as sociodemographic categories including educational status, body mass index, payer status, marital status, and gravidity. A subsample of medically low-risk childbearing people, qualified for birth center admission in labor, was analyzed to assess variations in maternal and newborn outcomes by site of first admission in labor. RESULTS: While overall clinical outcomes exceeded national benchmarks across all places of admission in the sample, disparities were noted including higher cesarean birth rates among Black and Hispanic people. This variation was larger within the population of people who preferred to be admitted to the hospital in labor in the absence of medical indication. CONCLUSION: This study supports that the birth center model provides safe delivery care across the intersections of US sociodemographics. Findings from this study highlight the importance of increased access and choice in place of birth for improving health equity, including decreasing cesarean birth and increasing breastfeeding initiation.

BACKGROUND: U.S. healthcare costs have increased exponentially to almost $4 trillion. Despite increased costs, patient outcomes remain suboptimal. It is imperative that primary care providers are intentional with testing and medical technology to improve effective care. LOCAL PROBLEM: Preintervention chart audits showed average overspending of $79.41 per provider per day. Despite overspending, outcomes are not optimal. Only 48% of persons with hypertension and 38% of persons with diabetes at Orange Blossom Family Health (OBFH) are controlled. The aim of this 8-week quality improvement (QI) project was to decrease lab spending by 20% for adult primary care patients at OBFH. METHODS: A rapid cycle QI initiative of four Plan-Do-Study-Act cycles, 2 weeks each, was completed to implement four interventions concurrently. The data was assessed every 2 weeks with iterative tests of change as indicated. INTERVENTIONS: The primary care quality metrics chart audit and preclinical care coordination tools were developed, and the My Life, My Healthcare tool and medical assistant (MA)-provider huddles were initiated with the focus on effective patient care. RESULTS: A savings of $3406.43 on overordering of labs by one provider in 8 weeks was identified. The average provider compliance to national guidelines was found to be 54.1%. There was a 19.3% increase in referrals. MA-provider huddles were balanced for this initiative. CONCLUSIONS: The initiative addressed effective care through awareness of resource allocation, patient engagement, and team communication. Continued application of these core interventions will ensure consistent and quality healthcare.

INTRODUCTION: Expansion of the midwifery-led birth center model of care is one pathway to improving maternal and newborn health. There are a variety of practice types among birth centers and a range of state regulatory structures of midwifery practice across the United States. This study investigated how those variations relate to pay and workload for midwives at birth centers. METHODS: Data from the American Association of Birth Centers Practice Survey and the Bureau of Labor Statistics' report on occupational employment and wage statistics were analyzed to explore how midwife salaries and workload at birth centers compare within and beyond the birth center model. RESULTS: Survey results from 161 birth centers across the United States demonstrate wide variation in nurse-midwife salaries and are inconsistent with nurse-midwife salaries across all settings as reported by the Bureau of Labor Statistics. The reported number of hours worked by midwives within the birth center model is high. Salaries of midwives who work in birth center-only practices were consistently lower than salaries of midwives who worked in blended birth center and hospital practices, independent of the midwife's level of experience, geographic region of the country, and state regulatory structure. DISCUSSION: Further research is needed to understand how to bring salaries and workload for midwives at birth centers into alignment with national averages.

Maternal and newborn outcomes in the United States are suboptimal. Care provided by certified nurse-midwives and certified midwives is associated with improved health outcomes for mothers and newborns. Benchmarking is a process of continuous quality assurance providing opportunities for internal and external improvement. Continuous quality improvement is a professional standard and expectation for the profession of midwifery. The American College of Nurse-Midwives Benchmarking Project is an example of a long-standing, midwifery-led quality improvement program. The project demonstrates a program for midwifery practices to display and compare their midwifery processes and outcomes of care. Quality metrics in the project reflect national quality measures in maternal child health while intentionally showcasing the contributions of midwives. The origins of the project and the outcomes for data submitted for 2019 are described and compared with national rates. The American College of Nurse-Midwives Benchmarking Project provides participating midwifery practices with information for continuous improvement and documents the high quality of care provided by a sample of midwifery practices.

The purpose of this study is to explore the National Quality Strategy (NQS) levers (measurement and feedback, public reporting, learning and technical assistance, and certification) on state and national breastfeeding performance. The research evaluates the NQS levers of measurement and feedback and public reporting using secondary data analysis of publicly reported data from the National Immunization Survey and the Centers for Disease Control and Prevention Breastfeeding Report Cards between 2008 and 2018, the latest years available. Linear regression explores the association between the prevalence of state-level Baby-Friendly hospitals and state-level breastfeeding rates. Subsequent analyses use event study to test whether state-level Baby-Friendly hospital adoption is associated with higher breastfeeding rates. A 10% increase in Baby-Friendly hospitals at the state level is associated with increased population breastfeeding rates by nearly 5% and a decrease in early formula use (before 2 days of life) by 2% to 9%. Breastfeeding increased by 2% to 5% in the first 2 years following state-level Baby-Friendly initiatives, with subsequent increases up to 10% in the next 4 years. The National Quality Strategy levers of measurement and public reporting combined with certification and learning and technical assistance are associated with increases in exclusive breastfeeding, a national quality metric.

BACKGROUND: At many hospitals, the cesarean birth rate among nulliparous term singleton vertex (NTSV) pregnancies is higher than World Health Organization benchmarks. Reducing NTSV cesarean birth is a national quality imperative. The aim of this initiative was to implement an evidence-based bundle at an urban community teaching hospital in at least 50% of labors in 60 days in order to reduce early labor admissions and increase adherence to evidence-based labor management guidelines shown to decrease cesarean birth. METHODS: Chart audits, root-cause analysis, and staff engagement informed bundle development. An early labor triage guide, labor walking path, partograph, and pre-cesarean checklist were implemented to drive change. Four Rapid Cycle Plan Do Study Act cycles were conducted over 8 weeks. RESULTS: The bundle was implemented in 58% of births. The bundle reduced early labor admissions labor from 41% to 25%. Team knowledge reflecting current guidelines in labor management increased 35% and 100% of cesareans for labor arrest met criteria. Patient satisfaction scores exceeded 98%. CONCLUSIONS: Implementing an evidenced-based bundle was effective in reducing early labor admissions and increasing utilization of and adherence to labor management guidelines. IMPLICATIONS FOR NURSING: Implementation of evidence-based bundles has the potential to achieve meaningful quality improvements in maternity care.
RESUMEN
INTRODUCTION: Current US guidelines for the care of women with obesity generalize obesity-related risks to all women regardless of overall health status and assume that birth will occur in hospitals. Perinatal outcomes for women with obesity in US freestanding birth centers need documentation. METHODS: Pregnancies recorded in the American Association of Birth Centers Perinatal Data Registry were analyzed (n = 4,455) to form 2 groups of primiparous women (n = 964; 1:1 matching of women with normal body mass indices [BMIs] and women with obese BMIs [>30]), using propensity score matching to address the imbalance of potential confounders. Groups were compared on a range of outcomes. Differences between groups were evaluated using χ2 test for categorical variables and Student's t test for continuous variables. Paired t test and McNemar's test evaluated the differences among the matched pairs. RESULTS: The majority of women with obese BMIs experienced uncomplicated perinatal courses and vaginal births. There were no significant differences in antenatal complications, proportion of prolonged pregnancy, prolonged first and second stage labor, rupture of membranes longer than 24 hours, postpartum hemorrhage, or newborn outcomes between women with obese BMIs and normal BMIs. Among all women with intrapartum referrals or transfers (25.3%), the primary indications were prolonged first stage or second stage (55.4%), inadequate pain relief (14.8%), client choice or psychological issue (7.0%), and meconium (5.3%). Primiparous women with obesity who started labor at a birth center had a 30.7% transfer rate and an 11.1% cesarean birth rate. DISCUSSION: Women with obese BMIs without medical comorbidity can receive safe and effective midwifery care at freestanding birth centers while anticipating a low risk for cesarean birth. The risks of potential, obesity-related perinatal complications should be discussed with women when choosing place of birth; however, pregnancy complicated by obesity must be viewed holistically, not simply through the lens of obesity.
