Trends in Cesarean Delivery in Puerto Rico, 2018-2022.

Cesarean delivery is major surgery associated with higher costs and adverse outcomes, such as surgical complications, compared with vaginal delivery (1-3). The cesarean delivery rate in Puerto Rico rose from just over 30% in the early to mid-1990s to over 40% by the early 2000s (4,5). During this time, cesarean delivery rates in Puerto Rico were 40%-70% higher than rates in the U.S. mainland and up to 78% higher than rates for Hispanic women in the U.S. mainland (4,5). This report describes trends in Puerto Rico's cesarean delivery rate from 2010 to 2022 and explores changes by maternal age, gestational age, and municipality from 2018 to 2022.

Inequalities in prevalence of birth by caesarean section in Ghana from 1998-2014.

BACKGROUND: Caesarean section (CS) is an intervention to reduce maternal and perinatal mortality, for complicated pregnancy and labour. We analysed trends in the prevalence of birth by CS in Ghana from 1998 to 2014. METHODS: Using the World Health Organization's (WHO) Health Equity Assessment Toolkit (HEAT) software, data from the 1998-2014 Ghana Demographic and Health Surveys (GDHS) were analysed with respect of inequality in birth by CS. First, we disaggregated birth by CS by four equity stratifiers: wealth index, education, residence, and region. Second, we measured inequality through simple unweighted measures (Difference (D) and Ratio (R)) and complex weighted measures (Population Attributable Risk (PAR) and Population Attributable Fraction (PAF)). A 95% confidence interval was constructed for point estimates to measure statistical significance. RESULTS: The proportion of women who underwent CS increased significantly between 1998 (4.0%) and 2014 (12.8%). Throughout the 16-year period, the proportion of women who gave birth by CS was positively skewed towards women in the highest wealth quintile (i.e poorest vs richest: 1.5% vs 13.0% in 1998 and 4.0% vs 27.9% in 2014), those with secondary education (no education vs secondary education: 1.8% vs 6.5% in 1998 and 5.7% vs 17.2% in 2014) and women in urban areas (rural vs urban 2.5% vs 8.5% in 1998 and 7.9% vs 18.8% in 2014). These disparities were evident in both complex weighted measures of inequality (PAF, PAR) and simple unweighted measures (D and R), although some uneven trends were observed. There were also regional disparities in birth by CS to the advantage of women in the Greater Accra Region over the years (PAR 7.72; 95% CI 5.86 to 9.58 in 1998 and PAR 10.07; 95% CI 8.87 to 11.27 in 2014). CONCLUSION: Ghana experienced disparities in the prevalence of births by CS, which increased over time between 1998 and 2014. Our findings indicate that more work needs to be done to ensure that all subpopulations that need medically necessary CS are given access to maternity care to reduce maternal and perinatal deaths. Nevertheless, given the potential complications with CS, we advocate that the intervention is only undertaken when medically indicated.

Why do women attend antenatal care but give birth at home? a qualitative study in a rural Ghanaian District.

BACKGROUND: The Sustainable Development Goal Three has prioritised reducing maternal, under-5 and neonatal mortalities as core global health policy objectives. The place, where expectant mothers choose to deliver their babies has a direct effect on maternal health outcomes. In sub-Saharan Africa, existing literature has shown that some women attend antenatal care during pregnancy but choose to deliver their babies at home. Using the Andersen and Newman Behavioural Model, this study explored the institutional and socio-cultural factors motivating women to deliver at home after attending antenatal care. METHODS: A qualitative, exploratory, cross-sectional design was deployed. Data were collected from a purposive sample of 23 women, who attended antenatal care during pregnancy but delivered their babies at home, 10 health workers and 17 other community-level stakeholders. The data were collected through semi-structured interviews, which were audio-recorded, transcribed and thematically analysed. RESULTS: In line with the Andersen and Newman Model, the study discovered that traditional and religious belief systems about marital fidelity and the role of the gods in childbirth, myths about consequences of facility-based delivery, illiteracy, and weak women's autonomy in healthcare decision-making, predisposed women to home delivery. Home delivery was also enabled by inadequate midwives at health facilities, the unfriendly attitude of health workers, hidden charges for facility-based delivery, and long distances to healthcare facilities. The fear of caesarean section, also created the need for women who attended antenatal care to deliver at home. CONCLUSION: The study has established that socio-cultural and institutional level factors influenced women's decisions to deliver at home. We recommend a general improvement in the service delivery capacity of health facilities, and the implementation of collaborative educational and women empowerment programmes by stakeholders, to strengthen women's autonomy and reshape existing traditional and religious beliefs facilitating home delivery.

Rates and indications of caesarean section deliveries in Bhutan 2015-2019: a national review.

BACKGROUND: Bhutan has made much efforts to provide timely access to health services during pregnancy and increase institutional deliveries. However, as specialist obstetric services became available in seven hospitals in the country, there has been a steady increase in the rates of caesarean deliveries. This article describes the national rates and indications of caesarean section deliveries in Bhutan. METHODS: This is a review of hospital records and a qualitative analysis of peer-reviewed articles on caesarean deliveries in Bhutan. Data on the volume of all deliveries that happened in the country from 2015 to 2019 were retrieved from the Annual Health Bulletins published by the Ministry of Health. The volume of deliveries and caesarean deliveries were extracted from the Annual Report of the National Referral Hospital 2015-2019 and the data were collected from hospital records of six other obstetric centres. A national rate of caesarean section was calculated as a proportion out of the total institutional deliveries at all hospitals combined. At the hospital level, the proportion of caesarean deliveries are presented as a proportion out of total institutional deliveries conducted in that hospital. RESULTS: For the period 2015-2019, the average national rate of caesarean section was 20.1% with a statistically significant increase from 18.1 to 21.5%. The average rate at the six obstetric centres was 29.9% with Phuentsholing Hospital (37.2%), Eastern Regional Referral Hospital (34.2%) and Samtse General Hospital (32.0%) reporting rates higher than that of the National Referral Hospital (28.1%). Except for the Eastern Regional Referral and Trashigang Hospitals, the other three centres showed significant increase in the proportion of caesarean deliveries during the study period. The proportion of emergency caesarean section at National Referral Hospital, Central Regional Referral Hospital and the Phuentsholing General Hospital was 58.8%. The National Referral Hospital (71.6%) and Phuentsholing General Hospital reported higher proportions of emergency caesarean sections (64.4%) while the Central Regional Referral Hospital reported higher proportions of elective sections (59.5%). The common indications were 'past caesarean section' (27.5%), foetal distress and non-reassuring cardiotocograph (14.3%), failed progress of labour (13.2%), cephalo-pelvic disproportion or shoulder dystocia (12.0%), and malpresentation including breech (8.8%). CONCLUSION: Bhutan's caesarean section rates are high and on the rise despite a shortage of obstetricians. This trend may be counterproductive to Bhutan's efforts towards 2030 Sustainable Development Goal agendas and calls for a review of obstetric standards and practices to reduce primary caesarean sections.

Changes in maternal risk factors and their association with changes in cesarean sections in Norway between 1999 and 2016: A descriptive population-based registry study.

BACKGROUND: Increases in the proportion of the population with increased likelihood of cesarean section (CS) have been postulated as a driving force behind the rise in CS rates worldwide. The aim of the study was to assess if changes in selected maternal risk factors for CS are associated with changes in CS births from 1999 to 2016 in Norway. METHODS AND FINDINGS: This national population-based registry study utilizes data from 1,055,006 births registered in the Norwegian Medical Birth Registry from 1999 to 2016. The following maternal risk factors for CS were included: nulliparous/≥35 years, multiparous/≥35 years, pregestational diabetes, gestational diabetes, hypertensive disorders, previous CS, assisted reproductive technology, and multiple births. The proportion of CS births in 1999 was used to predict the number of CS births in 2016. The observed and predicted numbers of CS births were compared to determine the number of excess CS births, before and after considering the selected risk factors, for all births, and for births stratified by 0, 1, or >1 of the selected risk factors. The proportion of CS births increased from 12.9% to 16.1% (+24.8%) during the study period. The proportion of births with 1 selected risk factor increased from 21.3% to 26.3% (+23.5%), while the proportion with >1 risk factor increased from 4.5% to 8.8% (+95.6%). Stratification by the presence of selected risk factors reduced the number of excess CS births observed in 2016 compared to 1999 by 67.9%. Study limitations include lack of access to other important maternal risk factors and only comparing the first and the last year of the study period. CONCLUSIONS: In this study, we observed that after an initial increase, proportions of CS births remained stable from 2005 to 2016. Instead, both the size of the risk population and the mean number of risk factors per birth continued to increase. We observed a possible association between the increase in size of risk population and the additional CS births observed in 2016 compared to 1999. The increase in size of risk population and the stable CS rate from 2005 and onward may indicate consistent adherence to obstetric evidence-based practice in Norway.

The effect of a new maternity unit on maternal outcomes in rural Haiti: an interrupted time series study.

BACKGROUND: In Haiti where there are high rates of maternal and neonatal mortality, efforts to reduce mortality and improve maternal newborn child health (MNCH) must be tracked and monitored to measure their success. At a rural Haitian hospital, local surveillance efforts allowed for the capture of MNCH indicators. In March 2018, a new stand-alone maternity unit was opened, with increased staff, personnel, and physical space. We aimed to determine if the new maternity unit brought about improvements in maternal and neonatal outcomes. METHODS: We conducted an interrupted time series analysis using data collected between July 2016 and October 2019 including 20 months before the opening of the maternity unit and 20 months after. We examined maternal-neonatal outcomes such as physiological (vaginal) births, caesarean birth, postpartum hemorrhage (PPH), maternal deaths, stillbirths and undesirable outcomes (eclampsia, PPH, perineal laceration, postpartum infection, maternal death or stillbirth). RESULTS: Immediately after the opening of the new maternity, the number of physiological births decreased by 7.0% (ß = - 0.070; 95% CI: - 0.110 to - 0.029; p = 0.001) and there was an increase of 6.7% in caesarean births (ß = 0.067; 95% CI: 0.026 to 0.107; p = 0.002). For all undesirable outcomes, preintervention there was an increasing trend of 1.8% (ß = 0.018; 95% CI: 0.013 to 0.024; p < 0.001), an immediate 14.4% decrease after the intervention (ß = - 0.144; 95% CI: - 0.255 to - 0.033; p = 0.012), and a decreasing trend of 1.8% through the postintervention period (ß = - 0.018; 95% CI: - 0.026 to - 0.009; p < 0.001). No other significant level or trend changes were noted. CONCLUSIONS: The new maternity unit led to an upward trend in caesarean births yet an overall reduction in all undesirable maternal and neonatal outcomes. The new maternity unit at this rural Haitian hospital positively impacted and improved maternal and neonatal outcomes.

Using the Robson classification to assess caesarean section rates in Brazil: an observational study of more than 24 million births from 2011 to 2017.

BACKGROUND: Applying the Robson classification to all births in Brazil, the objectives of our study were to estimate the rates of caesarean section delivery, assess the extent to which caesarean sections were clinically indicated, and identify variation across socioeconomic groups. METHODS: We conducted a population-based study using routine records of the Live Births Information System in Brazil from January 1, 2011, to December 31, 2017. We calculated the relative size of each Robson group; the caesarean section rate; and the contribution to the overall caesarean section rate. We categorised Brazilian municipalities using the Human Development Index to explore caesarean section rates further. We estimated the time trend in caesarean section rates. RESULTS: The rate of caesarean sections was higher in older and more educated women. Prelabour caesarean sections accounted for more than 54 % of all caesarean deliveries. Women with a previous caesarean section (Group 5) made up the largest group (21.7 %). Groups 6-9, for whom caesarean sections would be indicated in most cases, all had caesarean section rates above 82 %, as did Group 5. The caesarean section rates were higher in municipalities with a higher HDI. The general Brazilian caesarean section rate remained stable during the study period. CONCLUSIONS: Brazil is a country with one of the world's highest caesarean section rates. This nationwide population-based study provides the evidence needed to inform efforts to improve the provision of clinically indicated caesarean sections. Our results showed that caesarean section rates were lower among lower socioeconomic groups even when clinically indicated, suggesting sub-optimal access to surgical care.

Trends in cesarean section rates in private and public facilities in rural eastern Maharashtra, India from 2010-2017.

INTRODUCTION: Rates of cesarean sections (CS) have increased dramatically over the past two decades in India. This increase has been disproportionately high in private facilities, but little is known about the drivers of the CS rate increase and how they vary over time and geographically. METHODS: Women enrolled in the Nagpur, India site of the Global Network for Women's and Children's Health Research Maternal and Neonatal Health Registry, who delivered in a health facility with CS capability were included in this study. The trend in CS rates from 2010 to 2017 in public and private facilities were assessed and displayed by subdistrict. Multivariable generalized estimating equations models were used to assess the association of delivering in private versus public facilities with having a CS, adjusting for known risk factors. RESULTS: CS rates increased substantially between 2010 and 2017 at both public and private facilities. The odds of having a CS at a private facility were 40% higher than at a public facility after adjusting for other known risk factors. CS rates had unequal spatial distributions at the subdistrict level. DISCUSSION: Our study findings contribute to the knowledge of increasing CS rates in both public and private facilities in India. Maps of the spatial distribution of subdistrict-based CS rates are helpful in understanding patterns of CS deliveries, but more investigation as to why clusters of high CS rates have formed in warranted.

The Hormonal Milieu by Different Labor Induction Methods in Women with Previous Cesarean Section: a Prospective Randomized Controlled Trial.

The physiological pattern of hormonal and signaling molecules associated with labor induction is not fully clear. We conducted a preliminary study in order to investigate hormonal changes during labor induction in women with previous cesarean section. Eighty-seven women at term, with previous cesarean section, were randomized to undergo induction of labor by breast stimulation or intracervical balloon and compared with spontaneous labor (controls). Maternal serum levels of oxytocin, prostaglandin F2α, prostaglandin E2, prolactin, estradiol, and cortisol were analyzed at 0, 3, and 6 h post-induction initiation. Fetal umbilical cord hormones were measured. No significant difference was found in the induction-to-delivery time or mode of delivery between the induction groups. Maternal serum oxytocin levels decreased to a lesser extent in the breast stimulation group vs. the control group (p=0.003, p<0.001). In the breast stimulation and control groups, prostaglandin E2 levels increased as labor progressed (p=0.005, 0.002, respectively). Prostaglandin F2α levels decreased over time in the balloon group (p=0.039), but increased in the control group (p=0.037). Both induction methods had similar outcomes. The hormonal studies ascertained the hypothesized mechanisms, with oxytocin level higher during breast stimulation and lower in balloon induction. These observations could help clinicians determine the appropriate method for cervical ripening in women with previous cesarean section. Larger future studies are needed to examine the effect of these hormonal trends on the rate of successful labor induction and complications, such as uterine rupture, in women with previous uterine scars.

Multi-Institutional Practice-Patterns in Fetal Congenital Heart Disease Following Implementation of a Standardized Clinical Assessment and Management Plan.

Background Prenatal diagnosis of congenital heart disease has been associated with early-term delivery and cesarean delivery (CD). We implemented a multi-institutional standardized clinical assessment and management plan (SCAMP) through the University of California Fetal-Maternal Consortium. Our objective was to decrease early-term (37-39 weeks) delivery and CD in pregnancies complicated by fetal congenital heart disease using a SCAMP methodology to improve practice in a high-risk and clinically complex setting. Methods and Results University of California Fetal-Maternal Consortium site-specific management decisions were queried following SCAMP implementation. This contemporary intervention group was compared with a University of California Fetal-Maternal Consortium historical cohort. Primary outcomes were early-term delivery and CD. A total of 496 maternal-fetal dyads with prenatally diagnosed congenital heart disease were identified, 185 and 311 in the historical and intervention cohorts, respectively. Recommendation for later delivery resulted in a later gestational age at delivery (38.9 versus 38.1 weeks, P=0.01). After adjusting for maternal age and site, historical controls were more likely to have a CD (odds ratio [OR],1.8; 95% CI, 2.1-2.8; P=0.004) and more likely (OR, 2.1; 95% CI, 1.4-3.3) to have an early-term delivery than the intervention group. Vaginal delivery was recommended in 77% of the cohort, resulting in 61% vaginal deliveries versus 50% in the control cohort (P=0.03). Among pregnancies with major cardiac lesions (n=373), vaginal birth increased from 51% to 64% (P=0.008) and deliveries ≥39 weeks increased from 33% to 48% (P=0.004). Conclusions Implementation of a SCAMP decreased the rate of early-term deliveries and CD for prenatal congenital heart disease. Development of clinical pathways may help standardize care, decrease maternal risk secondary to CD, improve neonatal outcomes, and reduce healthcare costs.

Tendencia de la cesárea: una reflexión desde la ética / Cesarean section trend: a reflection from ethics / Tendência à cesárea: uma reflexão a partir da ética

Resumen: Las estadísticas mundiales muestran una tendencia al alza en las tasas de cesáreas que superan el 15% recomendado por la OPS/OMS. Esta cirugía se ha convertido en la más frecuente en los países de ingresos medios y altos. Algunos estudios sugieren que no todas estas cesáreas estarían justificadas. Al respecto se plantean algunas reflexiones sobre los dilemas éticos que se pueden observar desde varias posiciones teóricas, como el consecuencialismo, el kantianismo, la ética de la virtud y la teoría feminista. A su vez, estos dilemas están inmersos en múltiples factores individuales, sociales y culturales, entre otros. Desde la salud pública se debe revisar el parámetro actual definido como "rango aceptable" de cesáreas, ya que puede ser demasiado bajo. Igualmente se recomienda la aplicación de medidas para fortalecer en los pacientes el deseo de un parto normal, cuando sea posible, a través de información y educación oportuna durante la atención prenatal. Las decisiones del profesional de la salud y de las mujeres deben estar respaldadas por la mejor información disponible.

Abstract: World statistics show an upward trend in Cesarean section rates that exceed the 15% recommended by PAHO / WHO. This surgery has become the most common in high- and middle-income countries. Some studies suggest that not all these caesarean sections would be justified. In this regard, some reflections are made on the ethical dilemmas that can be observed from various theoretical positions such as consequentialism, Kantianism, the ethics of virtue and feminist theory. In turn, these dilemmas are immersed in multiple individuals, social and cultural factors, among others. From Public Health, the current parameter defined as the "acceptable range" of Caesarean sections should be reviewed as it may be too low. It is also recommended that measures be applied to strengthen patients' desire for a normal delivery whenever possible through timely information and education during prenatal care. The decisions of the health professional and women must be supported by the best information available.

Comparación de la tasa de cesáreas de dos maternidades públicas del Uruguay / Comparison of the caesarean section rate of two publics health maternity in Uruguay / Comparação da taxa de cesariana de duas maternidades públicas no Uruguai

Se realizó un analisis de la tasa de cesáreas en dos maternidades públicas de referencia de Uruguay (Hospital de Clínicas y Centro Hospitalario Pereira Rossell) utilizando la clasificación de Robson para compararlas entre sí, mediante un estudio observacional, descriptivo, retrospectivo y transversal en un periodo de 10 años y 10 meses (2009-2019). Se analizaron 85.526 nacimientos (7.685 (8,9%) en el Clínicas vs 77.841 (91.1%) Pereira Rossell). El porcentaje de cesáreas por año en el Clínicas fue 49,2% ± 5 vs 29,3% ± 3 en Pereira Rossell. Los grupos de Robson más prevalentes fueron 1, 5A y 10 en el Clínicas vs 3, 1 y 5A en Pereira Rossell. En ambos centros los grupos con mayor contribución relativa a la tasa global de cesáreas fueron: 5A, 10 y 1. Ambos centros presentan un aumento en la tasa de cesárea en la última década, pese a que se asisten poblaciones dispares entre cada uno de ellos. Se debe seguir buscando estrategias que ayuden a reducir la tasa de cesáreas principalmente en pacientes sin cesáreas anteriores o con una única cesárea previa, en caso de no presentan contraindicaciones para el parto vaginal.

An analysis of the caesarean section rate was carried out in two reference public maternity wards in Uruguay (Hospital de Clínicas and Centro Hospitalario Pereira Rossell) using Robson's classification to compare them with each other, through an observational, descriptive, retrospective and cross-sectional study in a period 10 years and 10 months (2009-2019). 85,526 births were analyzed (7,685 (8.9%) in the Clinics vs 77,841 (91.1%) Pereira Rossell). The percentage of caesarean sections per year in the Clinics was 49.2% ± 5 vs 29.3% ± 3 in Pereira Rossell. The most prevalent Robson groups were 1, 5A and 10 in the Clinicas vs 3, 1 and 5A in Pereira Rossell. In both centers, the groups with the highest relative contribution to the overall rate of cesarean sections were: 5A, 10 and 1. Both centers show an increase in the rate of cesarean section in the last decade, despite the fact that different populations are attended between each of them. Strategies should continue to be sought to help reduce the rate of cesarean sections, mainly in patients without previous cesarean sections or with a single previous cesarean section, if they do not present contraindications for vaginal delivery.

Trend and Sociodemographic Correlates of Cesarean Section Utilization in Nepal: Evidence from Demographic and Health Surveys 2006-2016.

BACKGROUND: Addressing inequalities in accessing emergency obstetric care is crucial for reducing the maternal mortality ratio. This study was undertaken to examine the time trends and sociodemographic correlates of cesarean section (CS) utilization in Nepal between 2006 and 2016. Methods. Data from the Nepal Demographic and Health Surveys (NDHS) 2006, 2011, and 2016 were sourced for this study. Women who had a live birth in the last five years of the survey were the unit of analysis for this study. Absolute and relative inequalities in CS utilization were expressed in terms of rate difference and rate ratios, respectively. We used multivariable regression models to assess the CS rate by background sociodemographic characteristics of women. RESULTS: Age and parity-adjusted CS rates were found to have increased almost threefold (from 3.2%, 95% CI: 2.1-4.3 in 2006 to 10.5%; 95% CI: 8.9-11.9 in 2016) over the decade. In 2016, women from mountain region (3.0%), those from the lowest wealth quintile (2.4%), and those living in Karnali province (2.4%) had CS rate below 5%. Whereas women from the highest wealth quintile (25.1%), with higher education (21.2%), and those delivering in private facilities (37.1%) had CS rate above 15%. Women from the highest wealth quintile (OR-3.3; 95% CI: 1.6-7.0) compared to women from the lowest wealth quintile and those delivered in private/NGO-run facilities (OR-3.6; 95% CI: 2.7-4.9) compared to women delivering in public facilities were more than three times more likely to deliver by CS. CONCLUSION: To improve maternal and newborn health, strategies need to be revised to address the underuse of CS among poor, those living in mountain region and Province 2, Lumbini province, Karnali province, and Sudhurpaschim province. Simultaneously, there is a pressing need for policies, guidelines, and continuous monitoring of CS rates to reduce overuse among rich women, women with higher education, and those giving childbirth in private facilities.

From Embryotomy to Cesarean: Changes in Obstetric Operatory Techniques in Nineteenth- and Twentieth-Century Urban Brazil.

This article traces the historical processes by which Brazil became a world leader in cesarean sections. It demonstrates that physicians changed their position toward and use of different obstetric surgeries, in particular embryotomies and cesarean sections, over the course of the nineteenth and twentieth centuries. The authors demonstrate that Catholic obstetricians, building upon both advancements in cesarean section techniques and new civil legislation that gave some personhood to fetuses, began arguing that fetal life was on par with its maternal counterpart in the early twentieth century, a shift that had a lasting impact on obstetric practice for decades to come. In the second half of the twentieth century, cesarean sections proliferated in clinical practice, but abortions remained illegal. Most importantly, women remained patients to be worked on rather than active participants in their reproductive lives.

Temporal trends in between and within-country inequalities in caesarean delivery in low- and middle-income countries: a Bayesian analysis.

OBJECTIVE: To provide updated information about between-country variations, temporal trends and changes in inequalities within countries in caesarean delivery (CD) rates. DESIGN: Cross-sectional study of Demographic and Health Survey (DHS) during 1990-2018. SETTING: 74 low- and middle-income countries (LMICs). POPULATION: Women 15-49 years of age who had live births in the last 3 years. METHODS: Bayesian linear regression analysis was performed and absolute differences were calculated. MAIN OUTCOME MEASURE: Population-level CD by countries and sociodemographic characteristics of mothers over time. RESULTS: CD rates, based on the latest DHS rounds, varied substantially between the study countries, from 1.5% (95% CI 1.1-1.9%) in Madagascar to 58.9% (95% CI 56.0-61.6%) in the Dominican Republic. Of 62 LMICs with at least two surveys, 57 countries showed a rise in CD during 1990-2018, with the greatest increase in Sierra Leone (19.3%). Large variations in CD rates were observed across mother's wealth, residence, education and age, with a higher rate of CD by the richest and urban mothers. These inequalities have widened in many countries. Stratified analyses suggest greater provisioning of CD by the richest mothers in private facilities and poorest mothers in public facilities. CONCLUSIONS: CD rates varied substantially across geographical locations and over time, irrespective of public or private health facilities. Changes in CD rates continue across wealth, place of residence, education, and age of mother, and are widening in most study countries. TWEETABLE ABSTRACT: Increasing caesarean delivery rates were greater among the richest and urban mothers than their counterparts, with widened gaps in LMICs.

Stillbirth rates, service outcomes and costs of implementing NHS England's Saving Babies' Lives care bundle in maternity units in England: A cohort study.

OBJECTIVE: To assess implementation of the Saving Babies Lives (SBL) Care Bundle, a collection of practice recommendations in four key areas, to reduce stillbirth in England. DESIGN: A retrospective cohort study of 463,630 births in 19 NHS Trusts in England using routinely collected electronic data supplemented with case note audit (n = 1,658), and surveys of service users (n = 2,085) and health care professionals (n = 1,064). The primary outcome was stillbirth rate. Outcome rates two years before and after the nominal SBL implementation date were derived as a measure of change over the implementation period. Data were collected on secondary outcomes and process outcomes which reflected implementation of the SBL care bundle. RESULTS: The total stillbirth rate, declined from 4.2 to 3.4 per 1,000 births between the two time points (adjusted Relative Risk (aRR) 0.80, 95% Confidence Interval (95% CI) 0.70 to 0.91, P<0.001). There was a contemporaneous increase in induction of labour (aRR 1.20 (95%CI 1.18-1.21), p<0.001) and emergency Caesarean section (aRR 1.10 (95%CI 1.07-1.12), p<0.001). The number of ultrasound scans performed (aRR 1.25 (95%CI 1.21-1.28), p<0.001) and the proportion of small for gestational age infants detected (aRR 1.59 (95%CI 1.32-1.92), p<0.001) also increased. Organisations reporting higher levels of implementation had improvements in process measures in all elements of the care bundle. An economic analysis estimated the cost of implementing the care bundle at ~£140 per birth. However, neither the costs nor changes in outcomes could be definitively attributed to implementation of the SBL care bundle. CONCLUSIONS: Implementation of the SBL care bundle increased over time in the majority of sites. Implementation was associated with improvements in process outcomes. The reduction in stillbirth rates in participating sites exceeded that reported nationally in the same timeframe. The intervention should be refined to identify women who are most likely to benefit and minimise unwarranted intervention.
