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.

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 rates and medical necessity of cesarean delivery in China, 2012-2019: an inspiration from Jiangsu.

BACKGROUND: The World Health Organization (WHO) in 2015 stated that every effort should be made to provide cesarean delivery (CD) for women in need. In China, the two-child policy largely prompts the number of advanced age childbirth, which raises the possibility of an increasing number of women who need a c-section. The aim of this study was to assess the trends in the overall and medical indication-classified CD rates in the era of the two-child policy in Jiangsu, China. METHODS: A retrospective cross-sectional study of 291,448 women who delivered in 11 hospitals in Jiangsu province between 2012 and 2019 was conducted. Medical cesarean indication for each woman was ascertained by manually reviewing the medical records. The 291,448 women were divided into two subgroups according to the presence of the indications: the indicated group (7.80%) and the non-indicated group (92.20%). We then fitted joinpoint regression and log-binomial regression models to estimate trends in the CD rates across the study period. RESULTS: The overall CD rate was observed with a declining trend from 52.51% in 2012-2015 to 49.76% in 2016-2019 (adjusted RR, 0.92; 95% CI, 0.91-0.93; P < 0.001), along with an annual percentage change (APC) to be - 1.0 (95% CI, - 2.1 to 0.0) across the period. The participants were then divided into two subgroups according to the presence of medical CD indications: the indicated group (7.80%) and the non-indicated group (92.20%).We found the declining trend was most pronounced in the non-indicated group, with the CD rates decreased from 50.02% in 2012-2015 to 46.27% in 2016-2019 (adjusted RR, 0.90; 95% CI, 0.89-0.90; P < 0.001). By contrast, we observed a steady trend in the CD rate of the indicated group, which maintained from 87.47% in 2012-2015 to 86.57% in 2016-2019 (P = 0.448). In the indicated group, a higher risk of adverse pregnancy outcomes was revealed for those women who delivered vaginally as compared with those who received c-section. We further investigated that women with following specific indications had a higher proportion of vaginal delivery, i.e., pregnancy complications, fetal macrosomia, and pregnancy complicated with tumor (34.70%, 10.84%, and 16.34%, respectively). Women with the above 3 indications were observed with a higher risk of adverse pregnancy outcomes if delivered vaginally. The incidence rates of the medical indications among the general population increased considerably over the 8-year period (P < 0.001). CONCLUSIONS: Although the overall CD rate apparently decreased in the recent years, along with the decline of the unnecessary CD rate, a considerable proportion of indicated women were not provided with CD service in Jiangsu, China. Instead of targeting the overall CD rate, we need to take actions to reduce unnecessary CD rate and provide adequate c-section service for women with indications, particularly for those with underlying diseases and suspected fetal macrosomia.

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.

Mode of Delivery Does Not Affect the Risk of Inflammatory Bowel Disease.

BACKGROUND: Recent evidence suggests that exposures in early life that are known to influence microbiome development may affect the risk of developing inflammatory bowel disease (IBD). Cesarean section has been associated with altered colonization of commensal gut flora and is thought to predispose to immune-mediated diseases later in life. AIMS: To evaluate the risk of IBD, Crohn's Disease (CD), and Ulcerative Colitis (UC) according to mode of delivery (C-section vs vaginal delivery). METHODS: A systematic search was performed in PubMed and Embase. The primary outcome was the risk of IBD in individuals delivered vaginally compared to those born by C-section. Secondary outcomes were UC and CD risk according to mode of delivery and IBD risk in individuals born by emergent compared to elective C-section. Publication bias was evaluated by funnel plots and Egger's test. Study's quality was characterized using the Newcastle-Ottawa Scale. RESULTS: Ten studies fulfilled the inclusion criteria, of which seven were population-based. No publication bias was detected. Overall, 14.164 IBD patients and 4.206.763 controls were included. Being born by C-section was not associated with increased risk of IBD [OR 1.01, 95% CI (0.81-1.27), p = 0.92], CD [OR 1.15, 95% CI (0.94-1.42), p = 0.18] or UC [OR 0.94, 95% CI (0.61-1.45), p = 0.79]. No differences were found between emergent and elective C-section in IBD [OR 1.05, 95% CI (0.59-1,87), p = 0.87]. Substantial heterogeneity was found in statistical analysis, and further studies are needed. CONCLUSION: Overall, the risk of developing IBD was not affected by mode of delivery.

The Effect of the No Pain Labor & Delivery-Global Health Initiative on Cesarean Delivery and Neonatal Outcomes in China: An Interrupted Time-Series Analysis.

BACKGROUND: The proportion of live births by cesarean delivery (CD) in China is significant, with some, particularly rural, provinces reporting up to 62.5%. The No Pain Labor & Delivery-Global Health Initiative (NPLD-GHI) was established to improve obstetric and neonatal outcomes in China, including through a reduction of CD through educational efforts. The purpose of this study was to determine whether a reduction in CD at a rural Chinese hospital occurred after NPLD-GHI. We hypothesized that a reduction in CD trend would be observed. METHODS: The NPLD-GHI program visited the Weixian Renmin Hospital, Hebei Province, China, from June 15 to 21, 2014. The educational intervention included problem-based learning, bedside teaching, simulation drill training, and multidisciplinary debriefings. An interrupted time-series analysis using segmented logistic regression models was performed on data collected between June 1, 2013 and May 31, 2015 to assess whether the level and/or trend over time in the proportion of CD births would decline after the program intervention. The primary outcome was monthly proportion of CD births. Secondary outcomes included neonatal intensive care unit (NICU) admissions and extended NICU length of stay, neonatal antibiotic and intubation use, and labor epidural analgesia use. RESULTS: Following NPLD-GHI, there was a level decrease in CD with an estimated odds ratio (95% confidence interval [CI]) of 0.87 (0.78-0.98), P = .017, with odds (95% CI) of monthly CD reduction an estimated 3% (1-5; P < .001), more in the post- versus preintervention periods. For labor epidural analgesia, there was a level increase (estimated odds ratio [95% CI] of 1.76 [1.48-2.09]; P < .001) and a slope decrease (estimated odds ratio [95% CI] of 0.94 [0.92-0.97]; P < .001). NICU admissions did not have a level change (estimated odds ratio [95% CI] of 0.99 [0.87-1.12]; P = .835), but the odds (95% CI) of monthly reduction in NICU admission was estimated 9% (7-11; P < .001), greater in post- versus preintervention. Neonatal intubation level and slope changes were not statistically significant. For neonatal antibiotic administration, while the level change was not statistically significant, there was a decrease in the slope with an odds (95% CI) of monthly reduction estimated 6% (3-9; P < .001), greater post- versus preintervention. CONCLUSIONS: In a large, rural Chinese hospital, live births by CD were lower following NPLD-GHI and associated with increased use of labor epidural analgesia. We also found decreasing NICU admissions. International-based educational programs can significantly alter practices associated with maternal and neonatal outcomes.

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.

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.

Length of hospital stay after cesarean section in Denmark from 2004 to 2016: A national register-based study.

INTRODUCTION: Length of hospital stay after birth has decreased during the last decades, but nationwide data on length of hospital stay after cesarean section are lacking. Elements of Enhanced Recovery Programs were reported to reduce the length of hospital stay. The aim of this nationwide study was to describe the length of hospital stay after cesarean section in Denmark from 2004 to 2016 taking into account birth- and health-related factors as well as demographic changes and, further, to assess potential differences between the five Danish regions. MATERIAL AND METHODS: Length of hospital stay was assessed in 164 209 deliveries by cesarean section in Denmark from 2004 to 2016. Data were obtained from the Danish National Patient Register. All deliveries by cesarean section at gestational age <22 weeks were excluded. Median length of hospital stay was reported based on crude and adjusted analyses. RESULTS: The median length of hospital stay was significantly reduced by 39 hours (95% confidence interval [CI] 37.9-40.1), from 97 hours (4.0 days) in 2004 to 58 hours (2.4 days) in 2016. Reductions were observed among both planned and emergency cesarean sections. When birth- and health-related factors as well as demographic changes were accounted for, median length of hospital stay was reduced by 30 hours (95% CI 29.3-30.8) in the period. The decrease in length of hospital stay from 2004 to 2016 varied between the five Danish regions, with adjusted reductions between 19 and 46 hours. CONCLUSIONS: A nationwide decrease in length of hospital stay after cesarean section was observed from 2004 to 2016 across all five regions but with significant regional variations. Further studies on the optimal length of hospital stay are needed, especially with regard to implementation of enhanced recovery programs.

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 Delivery Rate after Cessation of the One-Child Policy in China.

OBJECTIVE: We aimed to describe changes in cesarean delivery (CD) rates after the change of the one-child policy in China by using the Robson classification in a large Chinese population. STUDY DESIGN: This retrospective cohort study included 91,015 women who delivered at ≥24 weeks of gestation at a large tertiary obstetric center in Shanghai, China from 2011 to 2016. We analyzed CD rate trend and CD contribution trend in each Robson group. Logistic regression was used to calculate the odds of CD while adjusting for confounding variables. RESULTS: The overall CD rate decreased from 49.0% in 2011 to 40.6% in 2016. In nulliparous women with singleton cephalic term pregnancy and planned CD, the CD contribution rate was reduced significantly from 29.3% in 2011 to 16.4% in 2016 (p < 0.001). In multiparous with a scarred uterus, the CD contribution rate began to increase from 3.8% in 2011 to 9.1% in 2016 (p < 0.001). Compared with delivery in 2011, delivery in 2016 was associated with a 37% (adjusted odds ratio [aOR]: 0.63; 95% confidence interval [CI]: 0.60-0.66) reduction in CD. This reduction was observed in both nulliparous women with singleton cephalic term pregnancy (aOR: 0.57; 95% CI: 0.54-0.60), and multiparous women with singleton cephalic term pregnancy without scar (aOR: 0.41; 95% CI: 0.30-0.55). CONCLUSION: The rate of cesarean delivery in our Chinese population has declined significantly in the past few years.

Identifying optimal labor and delivery nurse staffing: The case of cesarean births and nursing hours.

BACKGROUND: Numerous studies have identified a relationship between nurse staffing and adverse patient outcomes in medical / surgical patient populations. However, little is known about the impact of labor and delivery (L&D) nurse staffing and adverse birth outcomes, such as unintended cesarean delivery, in low-risk term-gestation women. PURPOSE: We examined nurse staffing patterns on the likelihood of cesarean sections (C-sections) among low- risk, full gestation births and provided a testing framework to distinguish optimal from ineffective levels of nurse staffing. METHODS: This retrospective descriptive study used hours of productive nursing time per delivery as the treatment variable to determine direct nursing time per delivery and its impact on the likelihood of a C-section. For comparisons, we also assessed the likelihood of augmentations and of inductions, as well as the number of neonatal intensive care unit (NICU) hours per birth. We limited our sample to those births between 37 and 42 weeks of gestation. Two complimentary models (the quadratic and piecewise regressions) distinguishing optimal staffing patterns from ineffective staffing patterns were developed. The study was implemented in eleven hospitals that are part of a large, integrated healthcare system in the Southwest. DISCUSSION: While a simple linear regression of the likelihood of a C-section on nursing hours per delivery indicated no statistically distinguishable effect, our 'optimal staffing' model indicated that nurse staffing hours employed by using a large sample of hospitals were actually minimizing C-sections (robustness checks are provided using similar model comparisons for the likelihood of augmentation and induction, and NICU hours). Where the optimal staffing models did not appear to be effective for augmentations, inductions, and NICU hours, we found significant differences between facilities (i.e., significant fixed effects for hospitals). In all specifications, we also controlled for weeks of gestation, race, sex of the child, and mother's age.

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.

Changes in the modes of twin birth in Victoria, 1983-2015.

OBJECTIVES: To examine changes in the modes of delivery of twins in Victoria over 33 years. DESIGN: Retrospective population-based study. SETTING, PARTICIPANTS: All twin births in Victoria, 1 January 1983 - 31 December 2015. MAJOR OUTCOMES: Mode of birth (vaginal, planned or unplanned caesarean delivery); indications for caesarean delivery. RESULTS: During 1983-2015, 32 187 twin pregnancies ended in live or stillbirths in Victoria. The proportion of twins born by caesarean delivery increased from 24% (156 twin deliveries) in 1983 to 71% (782 deliveries) in 2015. The proportion of twin births by planned caesarean delivery with twin pregnancy as the sole indication for caesarean delivery increased across this period from 1.8% (12 twin deliveries) to 21% (231 deliveries). The proportion of twin births by caesarean delivery and the proportion of caesarean twin deliveries with twin pregnancy as the principal indication each differed between Victorian regions. CONCLUSION: During 1983-2015, the proportion of twins born in Victoria by caesarean delivery increased almost threefold, mostly because caesarean delivery has become the preferred mode of birth for twin pregnancies. Regional differences in the delivery of twins suggest that the number of caesarean deliveries can be reduced with appropriate system and training support.

Transversus Abdominis Plane Block With Liposomal Bupivacaine for Pain After Cesarean Delivery in a Multicenter, Randomized, Double-Blind, Controlled Trial.

BACKGROUND: In women undergoing cesarean delivery under spinal anesthesia with intrathecal morphine, transversus abdominis plane (TAP) block with bupivacaine hydrochloride (HCl) may not improve postsurgical analgesia. This lack of benefit could be related to the short duration of action of bupivacaine HCl. A retrospective study reported that TAP block with long-acting liposomal bupivacaine (LB) reduced opioid consumption and improved analgesia following cesarean delivery. Therefore, we performed a prospective multicenter, randomized, double-blind trial examining efficacy and safety of TAP block with LB plus bupivacaine HCl versus bupivacaine HCl alone. METHODS: Women (n = 186) with term pregnancies undergoing elective cesarean delivery under spinal anesthesia were randomized (1:1) to TAP block with LB 266 mg plus bupivacaine HCl 50 mg or bupivacaine HCl 50 mg alone. Efficacy was evaluated in a protocol-compliant analysis (PCA) set that was defined a priori. The primary end point was total postsurgical opioid consumption (oral morphine equivalent dosing [MED]) through 72 hours. Pain intensity was measured using a visual analog scale. Adverse events (AEs) after treatment were recorded through day 14. RESULTS: Total opioid consumption through 72 hours was reduced with LB plus bupivacaine HCl versus bupivacaine HCl alone (least squares mean [LSM] [standard error (SE)] MED, 15.5 mg [6.67 mg] vs 32.0 mg [6.25 mg]). This corresponded to an LSM treatment difference of -16.5 mg (95% confidence interval [CI], -30.8 to -2.2 mg; P = .012). The area under the curve of imputed pain intensity scores through 72 hours supported noninferiority of LB plus bupivacaine HCl versus bupivacaine HCl alone (LSM [SE], 147.9 [21.13] vs 178.5 [19.78]; LSM treatment difference, -30.6; 95% CI, -75.9 to 14.7), with a prespecified noninferiority margin of 36 (P = .002). In an analysis of all treated patients, including those not meeting criteria for inclusion in the PCA, there was no difference in postsurgical opioid consumption between groups. In the LB plus bupivacaine HCl group, 63.6% of patients experienced an AE after treatment versus 56.2% in the bupivacaine HCl-alone group. Serious AEs after treatment were rare (≈3% in both groups). CONCLUSIONS: TAP block using LB plus bupivacaine HCl as part of a multimodal analgesia protocol incorporating intrathecal morphine resulted in reduced opioid consumption after cesarean delivery in the PCA set. Results suggest that with correct TAP block placement and adherence to a multimodal postsurgical analgesic regimen, there is an opioid-reducing benefit of adding LB to bupivacaine TAP blocks after cesarean delivery (ClinicalTrials.gov identifier: NCT03176459).

Lithuania's experience in reducing caesarean sections among nulliparas: the impact of the quality improvement course.

BACKGROUND: To evaluate the role of the quality improvement course (QIC) to reduce the caesarean section (CS) rate among nulliparas (Robson groups 1 and 2) and to find out which group of women have reduced the CS rate following attendance at the course. METHODS: The QIC was organized in 2015. For the evaluation of the CS rate after the OIC, deliveries from the selected hospitals in 2014 and 2016 were compared using MS EXCEL and SPSS 23.0. RESULTS: Nulliparas accounted for 44.6% (3585/8046) and 42.9% (3628/8460) of all the deliveries in 2014 and 2016 years, respectively. The CS rate among nulliparas decreased from 19.0% (665/3502) in 2014 to 16.8% (593/3526) in 2016 (p = 0.018). The greatest decrease in absolute contribution to the overall CS rate was recorded in group 1 (p = 0.08). Perinatal mortality was 3.1 in 2014 and 3.9 in 2016 per 1000 deliveries (p = 0.569). CONCLUSION: The QIC has helped to reduce the CS rate among nulliparas without a negative influence on perinatal mortality. The greatest decrease in the overall CS rate was recorded among nulliparous women who were treated with oxytocin and managed to reach a full cervical dilatation.

Caesarean section rates from Malaysian tertiary hospitals using Robson's 10-group classification.

BACKGROUND: Rising caesarean section rates is a concern worldwide. This study aimed to use Robson's ten group classification to identify which groups of women were contributing most to the rising caesarean section rates in Malaysian tertiary hospitals and to compare between hospitals, using a common standard set of variables. METHODS: A 5-year (2011-2015) cross-sectional study was conducted using data from the Malaysian National Obstetrics Registry (NOR). A total of 608,747 deliveries were recorded from 11 tertiary state hospitals and 1 tertiary hospital from the Federal territory. RESULTS: During the study period, there were 141,257 Caesarean sections (23.2%). Caesarean sections in Group 1 (nulliparous term pregnancy in spontaneous labour) and Group 3 (multiparous term pregnancy in spontaneous labour) had an increasing trend from 2011 to 2015. The group that contributed most to the overall caesarean section rates was Group 5 (multiparous, singleton, cephalic≥37 weeks with previous caesarean section) and the rates remained high during the 5-year study period. Groups 6, 7 and 9 had the highest caesarean section rates but they made the smallest contribution to the overall rates. CONCLUSIONS: Like many countries, the rate of caesarean section has risen over time, and the rise is driven by caesarean section in low-risk groups. There was an important hospital to hospital variation. The rise in caesarean section rates reflects a globally disturbing trend, and changes in policy and training that creates a uniform standard across hospitals should be considered.

Trends in cesarean delivery rates in primipara and the associated factors.

BACKGROUND: Few studies have focused on cesarean delivery (CD) trends among primipara under the one-child and the two-child policies. This study aimed to explore the trends in CD rates among primipara during 1995-2019 and the associated factors with CD risk. METHODS: This study obtained clinical data on primiparous mothers and newborns from 1995 to 2019 at a large tertiary hospital in Wuhan, China. Trends in CD rates were calculated using the joinpoint regression analysis. The Chi-square tests and log-binomial regression analyses were used to evaluate the associations between primary variables and CD risk. RESULTS: CD rates showed a significant upward trend with an average annual percentage change (APC) of 2.2% (95% CI: 0.6, 3.8%) during the study period. In 1995-2006, the CD rates continued to increase with an APC of 7.8% (95% CI: 4.8, 10.9%). After 2006, the CD rates started to decline by an APC of - 4.1% (95% CI: - 5.5, - 2.6%). The CD rates non-significantly increased from 36.2% in 2016 to 43.2% in 2019. Moreover, the highest CD rate during 2015-2019 was observed on August 30 (59.2%) and the lowest on September 1 (29.7%). Primipara of older age and those with >3pregnancies had higher risks of CD. Furthermore, primipara who gave birth to newborns with low birth weight and macrosomia had higher risks of CD. CONCLUSIONS: Maternal and fetal as well as social and cultural factors may contribute to the rising trend of CD rates. Effective measures should be taken to control CD under the two-child policy, especially for primipara.

Childbirth care in Egypt: a repeat cross-sectional analysis using Demographic and Health Surveys between 1995 and 2014 examining use of care, provider mix and immediate postpartum care content.

BACKGROUND: Egypt has achieved important reductions in maternal and neonatal mortality and experienced increases in the proportion of births attended by skilled professionals. However, substandard care has been highlighted as one of the avoidable causes behind persisting maternal deaths. This paper describes changes over time in the use of childbirth care in Egypt, focusing on location and sector of provision (public versus private) and the content of immediate postpartum care. METHODS: We used five Demographic and Health Surveys conducted in Egypt between 1995 and 2014 to explore national and regional trends in childbirth care. To assess content of care in 2014, we calculated the caesarean section rate and the percentage of women delivering in a facility who reported receiving four components of immediate postpartum care for themselves and their newborn. RESULTS: Between 1995 and 2014, the percentage of women delivering in health facilities increased from 35 to 87% and women delivering with a skilled birth attendant from 49 to 92%. The percentage of women delivering in a private facility nearly quadrupled from 16 to 63%. In 2010-2014, fewer than 2% of women delivering in public or private facilities received all four immediate postpartum care components measured. CONCLUSIONS: Egypt achieved large increases in the percentage of women delivering in facilities and with skilled birth attendants. However, most women and newborns did not receive essential elements of high quality immediate postpartum care. The large shift to private facilities may highlight failures of public providers to meet women's expectations. Additionally, the content (quality) of childbirth care needs to improve in both sectors. Immediate action is required to understand and address the drivers of poor quality, including insufficient resources, perverse incentives, poor compliance and enforcement of existing standards, and providers' behaviours moving between private and public sectors. Otherwise, Egypt risks undermining the benefits of high coverage because of substandard quality childbirth care.

How does the two-child policy affect the sex ratio at birth in China? A cross-sectional study.

BACKGROUND: The One-Child Policy led to the imbalance of the sex ratio at birth (SRB) in China. After that, Two-Child Policy was introduced and gradually liberalized at three stages. If both the husband and wife of one couple were the only child of their parents, they were allowed to have two children in policy (BTCP). If only one of them was the only child, they were allowed to have two children in policy (OTCP). The Universal Two-Child Policy (UTCP) allowed every couple to have two children. The objective of this study was to explore the changing trend of SRB at the stages of Two-Child Policy, to analyze the effect of population policy on SRB in terms of maternal age, delivery mode, parity, maternal education, delivery hospital, and to figure out what factors have greater impact on the SRB. METHODS: The data of the study came from Hebei Province Maternal Near Miss Surveillance System, covered the parturients delivered at 28 gestation weeks or more in 22 hospitals from January 1, 2013 to December 31, 2017. We compared the SRB at different policy stages, analyzed the relationship between the SRB and population policy by logistic regression analysis. RESULTS: Total 270,878 singleton deliveries were analyzed. The SRB, 1.084 at BTCP, 1.050 at OTCP, 1.047 at UTCP, declined rapidly (χ2 = 15.97, P < 0.01). With the introduction of Two-Child Policy, the percentage of parturients who were 30-34, ≥35 years old rose significantly, and the percentage of multiparous women increased significantly (40.7, 47.2, 56.6%). The neonatal mortality declined significantly (8.4‰, 6.7‰, 5.9‰, χ2 = 44.49, P < 0.01), the mortality rate of female infant gradually declined (48.2, 43.7, 43.9%). The logistic regression analysis showed the SRB was correlated to the three population policy stages in terms of maternal age, delivery mode, parity, maternal education, delivery hospital. CONCLUSIONS: The SRB has declined to normal level with the gradually liberalizing of Two-Child Policy in China. Advanced maternal age, cesarean delivery, multiparous women, middle level education, rural hospital are the main factors of effect on the decline of the SRB.
