RESUMEN
INTRODUCTION: The J9 Plus (J9) maternal-child accompaniment program is based on four pillars: group antenatal care (GANC), group pediatric care, psychosocial support, and community-based care. We aimed to evaluate the impact of the J9 model of care on perinatal outcomes. METHODOLOGY: We conducted a convergent mixed methods study of maternal-newborn dyads born in 2019 at Hôpital Universitaire de Mirebalais. Quantitative data was collected retrospectively to compare dyads receiving J9 care to usual care. A secondary analysis of qualitative data described patient perspectives of J9 care. RESULTS: Antenatal care attendance was significantly higher among women in J9 (n = 524) compared to usual care (n = 523), with 490(93%) and 189(36%) having >4 visits, respectively; p <0.001, as was post-partum visit attendance [271(52%) compared to 84(16%), p<0.001] and use of post-partum family planning methods [98(19%) compared to 47(9%), p = 0.003]. Incidence of pre-eclampsia with severe features was significantly lower in the J9 group [44(9%)] compared to the usual care group [73(14%)], p <0.001. Maternal and neonatal mortality and low birth weight did not differ across groups. Cesarean delivery [103(20%) and 82(16%), p<0.001] and preterm birth [118 (24%)] and 80 (17%), p <0.001] were higher in the J9 group compared to usual care, respectively. In the qualitative analysis, ease of access to high-quality care, meaningful social support, and maternal empowerment through education were identified as key contributors to these outcomes. CONCLUSION: Compared to usual care, the J9 Plus maternal-child accompaniment model of care is associated with increased engagement in antenatal and postpartum care, increased utilization of post-partum family planning, and lower incidence of pre-eclampsia with severe features, which remains a leading cause of maternal mortality in Haiti. The J9 accompaniment approach to care is an empowering model that has the potential to be replicated in similar settings to improve quality of care and outcomes globally.

Objective: To evaluate if knowledge and awareness of concepts and concerns pertaining to reproductive health and fertility vary by race/ethnicity among reproductive-aged women in the United States. Methods: A 2013 cross-sectional web-based survey assessed reproductive health-related knowledge, awareness, and perceptions of 1,000 women (18-40 years). Multivariable logistic regression analyses, adjusting for age, education, income, marital status, employment, region, and pregnancy history, examined the association between race/ethnicity and subfertility-related risk factor awareness; knowledge of factors that may affect pregnancy susceptibility; and future fertility-related concerns. Results: Knowledge and awareness related to reproductive wellness and fertility differed by race/ethnicity in US women. Compared with Caucasians, Hispanic women were less likely to be aware of smoking-related harm to fertility (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.38-0.86); African American women were more aware of the implications of sexually transmitted infections on fertility (OR, 2.13; 95% CI, 1.15-3.94); and Asian women demonstrated greater awareness of a possible relationship between dysmenorrhea and subfertility (OR, 2.05; 95% CI, 1.09-3.86). Asian women consider fertility socially taboo to talk about and a private affair that is difficult to discuss (OR, 2.63; 95% CI, 1.32-5.29 and OR, 1.99; 95% CI, 1.05-3.75, respectively), were more concerned about their future fertility (OR, 2.36; 95% CI, 1.24-4.52), and more likely to perceive a need for future fertility treatment (OR, 2.36; 95% CI, 1.18-4.71). Conclusion: Among reproductive-aged women in the United States, knowledge, awareness, and perceptions relating to reproductive health vary by race/ethnicity. Our findings suggest race/ethnicity as potential modulators of population perceptions regarding reproductive health and infertility. Clinical Trial Registration Number: NIH ZIA# HD008985.
RESUMEN
OBJECTIVE: The cesarean delivery rate in the United States is 31.9%. One of the leading indications for primary cesarean delivery is labor arrest. A modern understanding of the labor curve supports more time prior to the diagnosis of labor arrest. We conducted this study to examine the impact of adherence to the modern criteria for labor arrest and failed induction on rates of primary cesarean delivery and to identify predictors of meeting these criteria. STUDY DESIGN: We analyzed rates of primary cesarean deliveries overall and primary cesarean deliveries occurring due to arrest of dilation, arrest of descent, and failed induction among the 17,877 live births at a large academic center from 2010 through 2013. Multiple logistic regression modeling identified predictors of meeting the new criteria for these indications based on guidelines published by the 2012 National Institute of Child Health and Human Development. RESULTS: The primary cesarean delivery rate decreased from 23.5 to 21.1% (p = 0.026) from 2010 to 2013. Primary cesarean delivery rate for labor arrest and failed induction decreased from 8.5 to 6.7% (p = 0.005). The percentage of primary cesarean deliveries meeting the 2012 criteria for labor arrest increased from 18.8 to 34.9% (p = 0.002), and the rate of primary cesarean deliveries due to arrest of dilation decreased from 5.1 to 3.4% (p < 0.0005). The percentage of cases meeting the 2012 criteria for arrest of descent increased from 57.8 to 71.0% (p < 0.007), while primary cesarean delivery rate due to arrest of descent remained relatively unchanged, 3.1 to 2.6% (p = 0.330). CONCLUSION: A decrease in the primary cesarean rate was attributable to a decrease in cesarean for arrest of dilation in the setting of a significant increase in meeting the 2012 criteria for arrest of dilation. At the end of the study period, 65.2% of cesareans still did not meet the criteria for arrest of dilation. Greater rates of adherence to these guidelines may yield further reductions in the cesarean rate. KEY POINTS: · Primary cesarean delivery for labor arrest was decreased.. · Meeting criteria for labor arrest increased.. · A hospitalist provider increased odds of meeting criteria..
RESUMEN
OBJECTIVE: In recent decades, there has been a call to foster effective collaborative models of practice between midwives and obstetricians/gynecologists (OB/GYNs) in the United States in order to improve clinician satisfaction and outcomes for childbearing women. Currently, there is no existing validated scale that measures the collaboration between obstetricians and midwives on labor and birth units. We sought to develop and validate a Midwifery- Obstetrics Collaboration (MOC) Scale that measures obstetricians' attitudes towards collaboration between obstetricians and midwives on labor and birth units. DESIGN: Validation study. The items in the questionnaire to be validated were developed de novo by the authors, based on their experiences and expertise in collaborative practice as well as by incorporating key principles of effective collaborative practice documented in the literature. The questionnaire was then piloted among 13 content experts. SETTING: Anonymous online survey conducted in the United States. PARTICIPANTS: We validated the questionnaire among 471 obstetricians in the United States from Sept 2019 to March 2020. The respondents included general obstetrician and gynecologists (OB/GYN) attendings, OB/GYN hospitalists, maternal fetal medicine (MFM) fellows and MFM attendings who practice on a labor and birth unit in the United States. MEASUREMENTS AND FINDINGS: We performed reliability analysis of the a priori items. We measured concurrent validity with an existing scale that measures inter-professional collaboration between nurses and physicians. We also correlated our scale with concerns for liability when working in a collaborative practice with midwives. Lastly, we measured discriminant validity with a single item burn out scale. The novel MOC Scale demonstrated construct and concurrent validity, and high inter-item reliability (a=0.93). The MOC Scale correlated with concerns about liability (r=0.63, p <0.001) but was not associated with burnout indicating the uniqueness of the new construct. KEY CONCLUSIONS: The MOC Scale is validated to assess collaboration between obstetricians and midwives on labor and birth units from an obstetrician's perspective IMPLICATIONS FOR PRACTICE: The MOC Scale can be used as a tool in clinical practice, to assess and foster effective collaboration between obstetricians and midwives from an obstetricians' perspective especially when used in conjunction with other tools that take into the account the perspectives of midwives and childbearing women.

OBJECTIVE: To examine interhospital variation in admissions to neonatal intensive care units (NICU) and reasons for the variation. STUDY DESIGN: 2010-2012 linked birth certificate and hospital discharge data from 35 hospitals in California on live births at 35-42 weeks gestation and ≥1500 g birth weight were used. Hospital variation in NICU admission rates was assessed by coefficient of variation. Patient/hospital characteristics associated with NICU admissions were identified by multivariable regression. RESULTS: Among 276,489 newborns, 6.3% were admitted to NICU with 34.5% of them having mild diagnoses. There was high interhospital variation in overall risk-adjusted rate of NICU admission (coefficient of variation = 26.2) and NICU admission rates for mild diagnoses (coefficient of variation: 46.4-74.0), but lower variation for moderate/severe diagnoses (coefficient of variation: 8.8-14.1). Births at hospitals with more NICU beds had a higher likelihood of NICU admission. CONCLUSION: Interhospital variation in NICU admissions is mostly driven by admissions for mild diagnoses, suggesting potential overuse.

OBJECTIVE: Trial of labor after cesarean delivery has been mostly studied in the setting of one prior cesarean delivery; controversy remains regarding the risks and benefits of trial of labor for women with two prior cesarean deliveries. This study aimed to examine utilization, success rate, and maternal and neonatal outcomes of trial of labor in this population. METHODS: Using linked hospital discharge and birth certificate data, we retrospectively analyzed a cohort of mothers with nonanomalous, term, singleton live births in California between 2010-2012 and had two prior cesarean deliveries and no clear contraindications for trial of labor. We measured whether they attempted labor and, if so, whether they delivered vaginally. Association of patient and hospital characteristics with the likelihood of attempting labor and successful vaginal birth was examined using multivariable regressions. We compared composite severe maternal morbidities and composite severe newborn complications in those who underwent trial of labor as opposed to planned cesarean delivery using a propensity score-matching approach. RESULTS: Among 42,771 women who met sample eligibility criteria, 1,228 (2.9%) attempted labor, of whom 484 (39.4%) delivered vaginally. There was no significant difference in the risk of composite severe maternal morbidities, but there was a modest increase in the risk of composite severe newborn complications among women who attempted labor compared with those who did not (2.0% vs 1.4%, P=.04). After accounting for differences in patient and hospital characteristics, propensity score-matched analysis showed no significant association between trial of labor and the risk of composite severe maternal morbidities (odds ratio [OR] 1.16, 95% CI 0.70-1.91), but trial of labor was associated with a higher risk for the composite of severe newborn complications (OR 1.78, 95% CI 1.04-3.04). CONCLUSION: Among women with two prior cesarean deliveries, trial of labor was rarely attempted and was successful in 39.4% of attempts. Trial of labor in this population was associated with a modest increase in severe neonatal morbidity.

OBJECTIVE: To evaluate the association between temporary cessation in oxytocin infusion (oxytocin rest) and mode of delivery in women undergoing induction of labor with a protracted latent phase. METHODS: We conducted a retrospective cohort analysis of nulliparous women with term, vertex, singleton gestations who were undergoing induction of labor with continuous oxytocin infusion at a large academic medical center. Episodes of oxytocin rest were identified among patients who were exposed to 8 hours of continuous oxytocin yet remained in latent labor (ie, protracted latent labor). Multivariable logistic regression analysis was performed to estimate the association between duration of oxytocin rest and mode of delivery while adjusting for duration of latent phase, maternal age, gestational age, body mass index, and indications for induction and oxytocin cessation. Maternal and neonatal morbidities were also compared among patients with different durations of oxytocin rest. RESULTS: From January 2012 to December 2016, 1,193 patients met eligibility criteria. Among these patients, 267 patients (22.4%) underwent an oxytocin rest that lasted at least 1 hour. After adjusting for potential confounders, the odds ratios of cesarean delivery for patients with oxytocin rest compared with those with no oxytocin rest were as follows: 1.12 (95% CI 0.79-1.58) for less than 1 hour, 0.78 (95% CI 0.48-1.27) for 1-2 hours, 0.60 (95% CI 0.35-1.04) for 2-8 hours, and 0.43 (95% CI 0.24-0.79) for 8 hours or more. We did not detect an association between oxytocin rest of more than 8 hours and a composite of maternal or neonatal morbidities. CONCLUSION: An oxytocin rest of at least 8 hours is a clinical tool that may reduce the risk of cesarean delivery among women with protracted latent labor without significantly increasing maternal or neonatal morbidity.

OBJECTIVES: Efforts to study potential overuse of NICU admissions and hospital variation in practice are often hindered by a lack of an appropriate data source. We examined the concordance of hospital-level NICU admission rates between birth certificate data and California Children's Services (CCS) data to inform the utility of birth certificate data in studying hospital variation in NICU admissions. METHODS: We analyzed birth certificate data from California in 2012 and hospital-specific summary data from CCS regarding NICU admissions. NICU admission rates were calculated for both data sets while using CCS data as the gold standard. The difference between birth certificate-based and CCS-based NICU admission rates was assessed by using the Wilcoxon signed rank test, and concordance between the 2 rates was evaluated by using Lin's concordance correlation coefficient and Kendall's W concordance coefficient. RESULTS: Among a total of 103 hospitals that were linked between the 2 data sets, birth certificate data generally underreported NICU admission rates compared with CCS data (median = 7.72% vs 11.51%; P < .001). However, in a subset of 35 hospitals where the difference in NICU admission rates between the 2 data sets was small, the birth certificate-based NICU admission rate showed good concordance with the rate from CCS data (Lin's concordance correlation coefficient = 0.91; 95% confidence interval: 0.84-0.95; Kendall's W concordance coefficient = 0.99; P < .001). Hospitals with good-concordance data did not differ from other hospitals in the institutional characteristics assessed. CONCLUSIONS: For a selected subset of hospitals, birth certificate data may offer a reasonable means to investigate hospital variation in NICU admissions.

INTRODUCTION: Despite evidence supporting the safety of low-interventional approaches to intrapartum care, defined by the American College of Obstetricians and Gynecologists as "practices that facilitate a physiologic labor process and minimize intervention," little is known about how frequently such practices are utilized. We examined hospital use of low-interventional practices, as well as variation in utilization across hospitals. METHODS: Data came from 185 California hospitals completing a survey of intrapartum care, including 9 questions indicating use of low- versus high-interventional practices (eg, use of intermittent auscultation, nonpharmacologic pain relief, and admission of women in latent labor). We performed a group-based latent class analysis to identify distinct groups of hospitals exhibiting different levels of utilization on these 9 measures. Multivariable logistic regression identified institutional characteristics associated with a hospital's likelihood of using low-interventional practices. Procedure rates and patient outcomes were compared between the hospital groups using bivariate analysis. RESULTS: We identified 2 distinct groups of hospitals that tended to use low-interventional (n = 44, 23.8%) and high-interventional (n = 141, 76.2%) practices, respectively. Hospitals more likely to use low-interventional practices included those with midwife-led or physician-midwife collaborative labor management (adjusted odds ratio [aOR], 7.52; 95% CI, 2.53-22.37; P < .001) and those in rural locations (aOR, 3.73; 95% CI, 1.03-13.60; P = .04). Hospitals with a higher proportion of women covered by Medicaid or other safety-net programs were less likely to use low-interventional practices (aOR, 0.96; 95% CI, 0.93-0.99; P = .004), as were hospitals in counties with higher medical liability insurance premiums (aOR, 0.53; 95% CI, 0.33-0.85; P = .008). Hospitals in the low-intervention group had comparable rates of severe maternal and newborn morbidities but lower rates of cesarean birth and episiotomy compared with hospitals in the high-intervention group. DISCUSSION: Only one-quarter of hospitals used low-interventional practices. Attention to hospital culture of care, incorporating the midwifery model of care, and addressing medical-legal concerns may help promote utilization of low-interventional intrapartum practices.

OBJECTIVE: To examine whether women who varied from recommended gestational weight gain guidelines by the Institute of Medicine (IOM, now known as the National Academy of Medicine) were at increased risk of severe maternal morbidity during delivery hospitalization compared with those whose weight gain remained within guidelines. METHODS: We conducted a retrospective cohort study using linked 2008-2012 New York City discharge and birth certificate data sets. Cases of severe maternal morbidity were identified using International Classification of Diseases, 9th Revision, Clinical Modification codes based on the Centers for Disease Control and Prevention criteria, which consists of 21 indicators of possible life-threatening diagnoses, life-saving procedures, or death. Multivariable logistic regression was used to evaluate the association between gestational weight gain categories based on prepregnancy body mass index (BMI) and severe maternal morbidity adjusting for maternal demographics and socioeconomic status. The analysis was stratified by prepregnancy BMI categories. RESULTS: During 2008-2012, there were 515,148 term singleton live births in New York City with prepregnancy weight and gestational weight gain information. In 24.8%, 35.1%, 32.1%, and 8.0% of these births, women gained below, within, 1-19 lbs above, and 20 lbs or more above the IOM guidelines, respectively. After adjusting for maternal demographic and socioeconomic characteristics, women who had gestational weight gain 1-19 lbs above (adjusted odds ratio [AOR] 1.08, 95% CI 1.02-1.13) or 20 lbs or more above the IOM recommendations (AOR 1.21, 95% CI 1.12-1.31) had higher odds of overall severe maternal morbidity compared with women who gained within guidelines. Although the increased odds ratios (ORs) were statistically significant, this only resulted in an absolute rate increase of 2.1 and 6 cases of severe maternal morbidity per 1,000 deliveries for those who gained 1-19 and 20 lbs or more above recommendations, respectively. Women with gestational weight gain 20 lbs or more above recommendations had significantly higher ORs of eclampsia, heart failure during a procedure, pulmonary edema or acute heart failure, transfusion, and ventilation. CONCLUSION: Women whose gestational weight gain is in excess of IOM guidelines are at increased risk of severe maternal morbidity, although their absolute risks remain low.

BACKGROUND: Cardiovascular disease is the leading cause of pregnancy-related death in the United States. Identification of short-term indicators of cardiovascular morbidity has the potential to alter the course of this devastating disease among women. It has been established that hypertensive disorders of pregnancy are associated with increased risk of cardiovascular disease 10-30 years after delivery; however, little is known about the association of hypertensive disorders of pregnancy with cardiovascular morbidity during the delivery hospitalization. OBJECTIVE: We aimed to identify the immediate risk of cardiovascular morbidity during the delivery hospitalization among women who experienced a hypertensive disorder of pregnancy. MATERIALS AND METHODS: This retrospective cohort study of women, 15-55 years old with a singleton gestation between 2008 and 2012 in New York City, examined the risk of severe cardiovascular morbidity in women with hypertensive disorders of pregnancy compared with normotensive women during their delivery hospitalization. Women with a history of chronic hypertension, diabetes mellitus, or cardiovascular disease were excluded. Mortality and severe cardiovascular morbidity (myocardial infarction, cerebrovascular disease, acute heart failure, heart failure or arrest during labor or procedure, cardiomyopathy, cardiac arrest and ventricular fibrillation, or conversion of cardiac rhythm) during the delivery hospitalization were identified using birth certificates and discharge record coding. Using multivariable logistic regression, we assessed the association between hypertensive disorders of pregnancy and severe cardiovascular morbidity, adjusting for relevant sociodemographic and pregnancy-specific clinical risk factors. RESULTS: A total of 569,900 women met inclusion criteria. Of those women, 39,624 (6.9%) had a hypertensive disorder of pregnancy: 11,301 (1.9%) gestational hypertension; 16,117 (2.8%) preeclampsia without severe features; and 12,206 (2.1%) preeclampsia with severe features, of whom 319 (0.06%) had eclampsia. Among women with a hypertensive disorder of pregnancy, 431 experienced severe cardiovascular morbidity (10.9 per 1000 deliveries; 95% confidence interval, 9.9-11.9). Among normotensive women, 1780 women experienced severe cardiovascular morbidity (3.4 per 1000 deliveries; 95% confidence interval, 3.2-3.5). Compared with normotensive women, there was a progressively increased risk of cardiovascular morbidity with gestational hypertension (adjusted odds ratio, 1.18; 95% confidence interval, 0.92-1.52), preeclampsia without severe features (adjusted odds ratio, 1.96; 95% confidence interval, 1.66-2.32), preeclampsia with severe features (adjusted odds ratio, 3.46; 95% confidence interval, 2.99-4.00), and eclampsia (adjusted odds ratio, 12.46; 95% confidence interval, 7.69-20.22). Of the 39,624 women with hypertensive disorders of pregnancy, there were 15 maternal deaths, 14 of which involved 1 or more cases of severe cardiovascular morbidity. CONCLUSION: Hypertensive disorders of pregnancy, particularly preeclampsia with severe features and eclampsia, are significantly associated with cardiovascular morbidity during the delivery hospitalization. Increased vigilance, including diligent screening for cardiac pathology in patients with hypertensive disorders of pregnancy, may lead to decreased morbidity for mothers.

OBJECTIVE: Placenta accreta is a feared pathology, in part, because prenatal diagnosis is imperfect. It is not known whether clinical risk factors or sonographic features equally predict the entire graded pathological spectrum of placental overinvasion disease nor whether clinical outcomes differ along the spectrum. STUDY DESIGN: We conducted a mixed methods retrospective study of a cohort of women screened sonographically for placenta accreta, cross-referenced against cases identified by pathological diagnosis (N = 416). Demographic, diagnostic, and outcome information were compared across the spectrum of invasive placentation: percreta, increta, accreta, and focal accreta not requiring hysterectomy. The t-test, chi-square, Mann-Whitney, and Kruskal-Wallis tests were used for statistical analysis across groups. RESULTS: As the depth of invasion decreased, risk factors for placental overinvasion were less common, especially placenta previa and previous cesarean. There was also reduced anticipation by sonographic examination of the placenta. Rates of adverse outcomes were lower among women with focal accreta compared with those with deeper invasion. CONCLUSION: As the depth of invasion decreases, clinical risk factors and sonographic evaluation are less reliable in the antenatal prediction of placenta accreta. The potential for unanticipated morbidity underscores the need for improved diagnostic tools for placenta accreta spectrum.

BACKGROUND: This study aims to examine hospital variation in both maternal and neonatal morbidities and identify institutional characteristics associated with hospital performance in a combined measure of maternal and neonatal outcomes. METHODS: Using the California Linked Birth File containing data from birth certificate and hospital discharge records, we identified 1 322 713 term births delivered at 248 hospitals during 2010-2012. For each hospital, a risk-standardized rate of severe maternal morbidities and a risk-standardized rate of severe newborn morbidities were calculated after adjusting for patient clinical risk factors. Hospitals were ranked based on combined information on their maternal and newborn morbidity rates. RESULTS: Risk-standardized severe maternal and severe newborn morbidity rates varied substantially across hospitals (10th to 90th percentile range = 67.5-148.2 and 141.8-508.0 per 10 000 term births, respectively), although there was no significant association between the two (P = 0.15). Government hospitals (non-Federal) were more likely than other hospitals to be in worse rank quartiles (P value for trend = 0.004), whereas larger volume was associated with better rank among hospitals in the first three quartiles (P = 0.004). The most prevalent morbidities that differed progressively across hospital rank quartiles were severe hemorrhage, disseminated intravascular coagulation, and heart failure during procedure/surgery for mothers, and severe infection, respiratory complication, and shock/resuscitation for neonates. CONCLUSIONS: Hospitals with low maternal morbidity rates may not have low neonatal morbidity rates and vice versa, highlighting the importance of assessing joint maternal-newborn outcomes in order to fully characterize a hospital's obstetrical performance. Hospitals with smaller volume and government ownership tend to have less desirable outcomes and warrant additional attention in future quality improvement efforts.

BACKGROUND: Trial of labor after cesarean delivery is an effective and safe option for women without contraindications. OBJECTIVES: The objective of the study was to examine hospital variation in utilization and success of trial of labor after cesarean delivery and identify associated institutional characteristics and patient outcomes. STUDY DESIGN: Using linked maternal and newborn hospital discharge records and birth certificate data in 2010-2012 from the state of California, we identified 146,185 term singleton mothers with 1 prior cesarean delivery and no congenital anomalies or clear contraindications for trial of labor at 249 hospitals. Risk-standardized utilization and success rates of trial of labor after cesarean delivery were estimated for each hospital after accounting for differences in patient case mix. Risk for severe maternal and newborn morbidities, as well as maternal and newborn length of stay, were compared between hospitals with high utilization and high success rates of trial of labor after cesarean delivery and other hospitals. Bivariate analysis was also conducted to examine the association of various institutional characteristics with hospitals' utilization and success rates of trial of labor after cesarean delivery. RESULTS: In the overall sample, 12.5% of women delivered vaginally. After adjusting for patient clinical risk factors, utilization and success rates of trial of labor after cesarean delivery varied considerably across hospitals, with a median of 35.2% (10th to 90th percentile range: 10.2-67.1%) and 40.5% (10th to 90th percentile range: 8.5-81.1%), respectively. Risk-standardized utilization and success rates of trial of labor after cesarean delivery demonstrated an inverted U-shaped relationship such that low or excessively high use of trial of labor after cesarean delivery was associated with lower success rate. Compared with other births, those delivered at hospitals with above-the-median utilization and success rates of trial of labor after cesarean delivery had a higher risk for uterine rupture (adjusted risk ratio, 2.74, P < .001), severe newborn respiratory complications (adjusted risk ratio, 1.46, P < .001), and severe newborn neurological complications/trauma (adjusted risk ratio, 2.48, P < .001), but they had a lower risk for severe newborn infection (adjusted risk ratio, 0.80, P = .003) and overall severe unexpected newborn complications (adjusted risk ratio, 0.86, P < .001) as well as shorter length of stays (adjusted mean ratio, 0.948 for mothers and 0.924 for newborns, P < .001 for both). Teaching status, system affiliation, larger volume, higher neonatal care capacity, anesthesia availability, higher proportion of midwife-attended births, and lower proportion of Medicaid or uninsured patients were positively associated with both utilization and success of trial of labor after cesarean delivery. However, rural location and higher local malpractice insurance premium were negatively associated with the utilization of trial of labor after cesarean delivery, whereas for-profit ownership was associated with lower success rate. CONCLUSION: Utilization and success rates of trial of labor after cesarean delivery varied considerably across hospitals. Strategies to promote vaginal birth should be tailored to hospital needs and characteristics (eg, increase availability of trial of labor after cesarean delivery at hospitals with low utilization rates while being more selective at hospitals with high utilization rates, and targeted support for lower capacity hospitals).

BACKGROUND: Evaluating trends in indications may identify targets to safely reduce the primary cesarean delivery rate. OBJECTIVE: The purpose of this study was to examine physician-documented indications for cesarean delivery to identify specific factors that contribute to a decreasing cesarean delivery rate. STUDY DESIGN: We analyzed rates of primary and repeat cesarean deliveries, which included indications for the procedure, among 22,265 live births at an academic tertiary center from 2009-2013. Time trends for each indication were modeled to estimate the absolute and cumulative annualized relative risk of cesarean delivery by indication over time and the relative contribution of each indication to the overall decrease in primary cesarean delivery rate. RESULTS: From 2009-2013, the cesarean delivery rate decreased from 36.5-31.4%; 74% of the decrease was attributable to a decrease in primary cesarean deliveries, which decreased from 21.7-17.6%. Among documented indications for primary cesarean delivery, labor arrest, abnormal or indeterminate fetal heart rate, and preeclampsia decreased significantly over time (P<.001), whereas malpresentation, multiple gestation, maternal-fetal, macrosomia, and other obstetric and elective/maternal requests did not change (P>.05). Labor arrest was responsible for the largest proportion of the decrease in the primary cesarean delivery rate (44%), followed by abnormal or indeterminate fetal heart rate (23%) and preeclampsia (13%). CONCLUSION: Primary cesarean births accounted for 74% of the decreasing cesarean delivery rate. Reductions in the diagnosis of labor arrest and abnormal fetal heart rate led to a decreased cesarean delivery rate at a major academic institution. Contemporaneous changes in definitions of labor arrest and approaches to fetal monitoring that were adopted at our institution may have considerable effect on the cesarean delivery rate.
