Non-clinical interventions for reducing unnecessary caesarean section

Intervention using the Robson classification as a tool to reduce cesarean section rates in six public hospitals in Brazil

OBJECTIVES

To analyze the effectiveness and safety of a multifaceted intervention to reduce cesarean section (CS) rates.

METHODS

This interrupted time series study involved six public hospitals with pre-intervention CS rates>35 %. We collected monthly data on overall and Robson group CS rates of 37,031 women who gave birth at the six hospitals during 30 months in the pre-intervention (12 months, n=14,836 women), intervention (6 months, n=6,431 women), and post-intervention (12 months, n=15,764 women) study periods. The intervention bundle included six components: audit and feedback using the Robson classification, goal setting for overall CS rate, distribution of evidence-based guidelines, informative meetings with hospital coordinators, newsletters, and inter-hospital mentoring.

RESULTS

There were no significant changes in mean overall CS rates between the three periods. However, five of the six hospitals had a significant decrease in CS rates in at least one Robson group during the study period: groups 1 and 5a (2 hospitals), group 2a (1 hospital), groups 4 and 4a (1 hospital), and group 5b (1 hospital). There were no significant increases in adverse events (maternal and perinatal mortality, neonatal asphyxia) in any of the hospitals with reductions in CS rates.

CONCLUSIONS

The multifaceted intervention did not significantly reduce the overall CS rate in the participating hospitals. However, five of the six hospitals had significant reductions in CS rates in at least one Robson group, without increasing adverse maternal or perinatal outcomes.

State-wise variation and inequalities in caesarean delivery rates in India: analysis of the National Family Health Survey-5 (2019-2021) data

Background

India's caesarean delivery (CD) rate of 21.5% suggests adequate national access to CD but may mask significant disparities. We examined variation in CD rates across states (geography), wealth, and health care sector (public versus private). We also aimed to determine relative inequality in CD rates across wealth quintiles.

Methods

The current study was a cross-sectional analysis of CD rates from the National Family Health Survey-5 (2019-2021) disaggregated by asset-based household wealth quintiles for each state and by healthcare sector (public versus private). Data from 724,115 women aged 15-49 years across 28 states and eight union territories were analysed. Women who reported their most recent live birth within the past five years were included. Relative inequality was measured by comparing CD rates in the richest versus the poorest quintiles.

Findings

Disaggregating the national CD rate of 21.5% showed substantial variation in CD rate across states, ranging from 5.2% in Nagaland to 60.7% in Telangana and across wealth quintiles, ranging from 0% to 76.7% (Assam). CD facility rates were higher in private than public facilities across all wealth quintiles. Over two-thirds of states (69%) had at least twice the CD rate in the richest wealth quintile versus the poorest quintile. Relative inequality in CD rates between the richest and poorest was 5.3 nationally and was higher in public (4.0) versus private (1.4) facilities.

Interpretation

The national CD rate in India masks complex geographical, wealth, and sector-related inequalities in CD utilisation. Accounting for these variations is imperative when interpreting national-level rates to better assess the equity in the distribution of CD services.

Maternal mortality following caesarean section in a low-resource setting: a National Malawian Surveillance Study

BACKGROUND

Caesarean section (CS) is the most common major surgery conducted globally, with rates rising. CS also contributes to maternal morbidity and mortality, with increased risks in low-resource settings. We conducted a detailed review of maternal deaths from 2020 to 2022 in Malawi to determine the burden of deaths related to CS, avoidable health system factors, and causes of death associated with this procedure.

METHODS

Data were collected regarding every maternal death occurring across all district and central hospitals in Malawi, alongside facility-level aggregated birth data. Maternal deaths were reviewed by facility-based multidisciplinary teams with subsequent confirmation of cause of death by obstetricians according to international criteria. Logistic regression was applied to estimate the odds of associations of leading causes of death with CS while adjusting for potential confounders.

RESULTS

Despite a low national CS rate, most deaths occurred following CS (51.8%, 276/533). Women who delivered by CS were five times (OR 5.60, 95% CI 4.74 to 6.67) more likely to die than women who delivered vaginally. The leading causes of death following CS were postpartum haemorrhage (26.0%, 68/277), eclampsia (15.6%, 41/277) and infection (14.1%, 37/277). Deaths from pregnancy-related infection were more often associated with CS (OR 2.03, 95% CI 1.12 to 3.72). Health system factors more frequently associated with deaths following CS than vaginal birth included 'prolonged abnormal observations without action' (p=0.006), 'delay in starting treatment' (p=0.006) and 'lack of blood transfusion' (p=0.03).

CONCLUSIONS

We found a high burden of maternal death following CS in this low-resource setting. Until now, international attention and many clinical trials have been focused on improving the safety of vaginal birth. Our findings highlight the need to ensure the safe and appropriate use of this potentially life-saving intervention to reduce maternal deaths. To avoid the high burden of death following CS we highlight, there is urgent need to develop and trial CS-specific interventions.

Evidence-Based Strategies to Minimize Unnecessary Primary Cesarean Sections: A Comprehensive Review

The increase in cesarean section (CS) rates, whether they are classified as unnecessary or elective, has globally raised significant concerns due to the associated risks involving maternal and neonatal outcomes. Although CS can be a lifesaving operation in specific medical cases, its overuse is exposing mothers and neonates to complications like hemorrhage, infections, and long-term consequences such as uterine scarring, infertility, and future pregnancy problems. The contributing factors include maternal preferences for convenience, fear of labor, and financial incentives within the healthcare systems that favor surgical interventions. Defensive medical practices and private healthcare providers further exacerbate this trend. This review discusses the prevalence of CS, highlighting variations between developing and developed regions and the complexity of addressing the rising rates. Moreover, recommendations to reduce unnecessary CS, such as enhancing antenatal education to inform mothers about the risks and benefits associated with different delivery options, promoting supportive care models (midwives), and fostering interdisciplinary cooperation among healthcare providers, will also be addressed. Healthcare systems will gain the ability to reduce the rates of unnecessary Cesarean procedures by directing the main focus on patient education, continuous monitoring, and policy reforms. This will lead to the improvement of both neonatal and maternal health outcomes in addition to lowering the costs of healthcare. In order to provide and ensure evidence-based and safe care for childbirth, a multidisciplinary approach is essential.

Trends and determinants of the use of episiotomy in a prospective population-based registry from central India

BACKGROUND

Findings from research and recommendations from the World Health Organization favor restrictive use of episiotomy, but whether this guidance is being followed in India, and factors associated with its use, are not known. This study sought to document trends in use of episiotomy over a five-year period (2014-2018); to examine its relationship to maternal, pregnancy, and health-system characteristics; and to investigate its association with other obstetric interventions.

METHODS

We conducted a secondary analysis of data collected by the Maternal Newborn Health Registry, a prospective population-based pregnancy registry established in Central India (Nagpur, Eastern Maharashtra). We examined type of birth and use of episiotomy in vaginal deliveries from 2014 to 2018, as well as maternal and birth characteristics, health systems factors, and concurrent obstetric interventions associations with its use with multivariable Poisson regression models.

RESULTS

During the five-year interval, the rate of episiotomy in vaginal birth rose from 13 to 31% despite a decline in assisted vaginal birth. Associations with episiotomy were found for the following factors: prior birth, multiple gestations, seven or more years of maternal education, higher gestational age, higher birthweight, delivery by an obstetrician (as compared to midwife or general physician), and birth in hospital (as compared to clinic or health center). After adjusting for these factors, year over year rise in episiotomy was significant with an adjusted incidence rate ratio (AIRR) of 1.10 [95% confidence interval (CI) 1.08-1.12; p = 0.002]. We found an association between episiotomy and several other obstetric interventions, with the strongest relationship for maternal treatment with antibiotics (AIRR 4.23, 95% CI 3.12-5.73; p = 0.001).

CONCLUSIONS

Episiotomy in this population-based sample from central India steadily rose from 2014 to 2018. This increase over time was observed even after adjusting for patient characteristics, obstetric risk factors, and health system features, such as specialty of the birthing provider. Our findings have important implications for maternal-child health and respectful maternity care given that most women prefer to avoid episiotomy; they also highlight a potential target for antibiotic stewardship as part of global efforts to combat antimicrobial resistance.

Effectiveness of de-implementation of low-value healthcare practices: an overview of systematic reviews

BACKGROUND

Reducing low-value care (LVC) is crucial to improve the quality of patient care while increasing the efficient use of scarce healthcare resources. Recently, strategies to de-implement LVC have been mapped against the Expert Recommendation for Implementing Change (ERIC) compilation of strategies. However, such strategies' effectiveness across different healthcare practices has not been addressed. This overview of systematic reviews aimed to investigate the effectiveness of de-implementation initiatives and specific ERIC strategy clusters.

METHODS

We searched MEDLINE (Ovid), Epistemonikos.org and Scopus (Elsevier) from 1 January 2010 to 17 April 2023 and used additional search strategies to identify relevant systematic reviews (SRs). Two reviewers independently screened abstracts and full texts against a priori-defined criteria, assessed the SR quality and extracted pre-specified data. We created harvest plots to display the results.

RESULTS

Of 46 included SRs, 27 focused on drug treatments, such as antibiotics or opioids, twelve on laboratory tests or diagnostic imaging and seven on other healthcare practices. In categorising de-implementation strategies, SR authors applied different techniques: creating self-developed strategies (n = 12), focussing on specific de-implementation strategies (n = 14) and using published taxonomies (n = 12). Overall, 15 SRs provided evidence for the effectiveness of de-implementation interventions to reduce antibiotic and opioid utilisation. Reduced utilisation, albeit inconsistently significant, was documented in the use of antipsychotics and benzodiazepines, as well as in laboratory tests and diagnostic imaging. Strategies within the adapt and tailor to context, develop stakeholder interrelationships, and change infrastructure and workflow ERIC clusters led to a consistent reduction in LVC practices.

CONCLUSION

De-implementation initiatives were effective in reducing medication usage, and inconsistent significant reductions were observed for LVC laboratory tests and imaging. Notably, de-implementation clusters such as change infrastructure and workflow and develop stakeholder interrelationships emerged as the most encouraging avenues. Additionally, we provided suggestions to enhance SR quality, emphasising adherence to guidelines for synthesising complex interventions, prioritising appropriateness of care outcomes, documenting the development process of de-implementation initiatives and ensuring consistent reporting of applied de-implementation strategies.

Effectiveness of shared decision-making for mode of delivery after caesarean section: A systematic review and meta-analysis of randomized controlled trials

AIM

To review the content, format and effectiveness of shared decision-making interventions for mode of delivery after caesarean section for pregnant women.

DESIGN

Systematic review and meta-analysis.

METHODS

Six databases (PubMed, Web of science Core Collection, Cochrance Network, Embase, CINAHL, PsycINFO) were searched starting at the time of establishment of the database to May 2023. Following the PRISMAs and use Review Manager 5.3 software for meta-analysis. Two review authors independently assessed the quality of the studies using the risk of bias 2 tool. The protocol was registered in PROSPERO (CRD42023410536).

RESULTS

The search strategy obtained 1675 references. After abstract and full text screening, a total of seven studies were included. Shared decision-making interventions include decision aids and counselling that can help pregnant women analyse the pros and cons of various options and help them make decisions that are consistent with their values. The pooled results showed that shared decision-making intervention alleviated decisional conflicts regarding mode of delivery after caesarean section, but had no effect on knowledge and informed choice.

CONCLUSION

The results of our review suggest that shared decision-making is an effective intervention to improve the quality of decision-making about the mode of delivery of pregnant women after caesarean section. However, due to the low quality of the evidence, it is recommended that more studies be conducted in the future to improve the quality of the evidence.

CORRELATION WITH CLINICAL PRACTICE

This systematic review and meta-analysis provides evidence for the effectiveness of shared decision-making for mode of delivery after cesarean section and may provide a basis for the development of intervention to promote the participation of pregnant women in the decision-making process.

Effect of psychological nursing intervention combined with acupressure on postoperative recovery of women after cesarean section

BACKGROUND

Psychological intervention nursing (PIN) has been considered to have a curative effect on cesarean section (CS) postoperative recovery. However, the therapeutic mechanisms remain obscure.

AIM

To explore the effects of PIN combined with acupressure massage on CS postoperative recovery.

METHODS

A retrospective study was conducted on 150 pregnant women admitted to an obstetrics department between January 2020 and January 2023. The control group (CG) received acupressure therapy (n = 73), and the intervention group (IG) received acupressure therapy and PIN therapy (n = 77). Postoperative recovery time was assessed by anal-exhausting, defecation, bed activity, breastfeeding, and hospital stay times. Adverse effects, including infection, bleeding, limb numbness, intrauterine hematoma, urinary retention, and venous thromboembolism, were recorded. the pain visual analogue scale (VAS) was used to evaluate the degree of pain. Anxiety and depression status were qualitatively assessed using the self-rating anxiety scale (SAS), self-rating depression scale (SDS), and Edinburgh postpartum depression scale (EPDS). The Pittsburgh sleep quality index (PSQI) was used to compare sleep quality between the groups.

RESULTS

The baseline data and SAS, SDS, EPDS, and PSQI scores did not significantly differ before CS (P > 0.05) and neither did complication rates between the two groups after CS (P > 0.05). However, anal-exhausting, defecation, waking up, breastfeeding, and hospitalization times were significantly shorter for participants in the IG than those for participants in the CG (P < 0.05). The VAS, SAS, SDS, EPDS, and PSQI scores of the IG were significantly lower than those of the CG (P < 0.05).

CONCLUSION

PIN, combined with acupressure massage, effectively promotes maternal recovery, reduces post-CS pain, and improves postoperative negative emotions and sleeping quality.

Exploring the feasibility of conducting a randomised controlled trial of group-based pregnancy care and education: a pilot randomised controlled trial in Melbourne, Australia

BACKGROUND

In group-based pregnancy models, antenatal care and childbirth/parenting education are provided in groups of eight to 10 women, usually with two midwives, and six to eight sessions. Current evidence is inconclusive regarding potential benefit or harm. We aimed to explore the feasibility of implementing an adequately powered randomised controlled trial (RCT).

METHODS

A two-arm pilot RCT was conducted in a tertiary maternity hospital in Melbourne, Australia. Women were randomly allocated to either the intervention to receive group-based antenatal care and education (group care) or to usual care, which included hospital-based midwife, caseload midwifery, team midwifery, or GP shared care. Participants were English-speaking, primiparous, low risk, and < 24 weeks gestation at booking.

DATA COLLECTION

feasibility measures throughout pilot, baseline questionnaire at recruitment, clinical outcome data from the medical record, and a telephone-administered questionnaire 6 weeks postpartum. A focus group explored midwives' views.

RESULTS

Seventy-four women were recruited from May to June 2017 (group care = 40, usual care = 34). Study uptake was 35%. Women allocated to group care rated their overall pregnancy care more highly (88% good/very good vs 77% in usual care). There was no evidence of harm related to group care. Overarching themes from the midwives were that group care helped 'build connections' and 'empower women'. All midwives would work in the model again and believed it should be expanded.

CONCLUSION

Group care was acceptable to both women and midwives with no evidence of harm. The pilot demonstrated the feasibility of undertaking a large adequately powered RCT, important given the inconclusive evidence on clinical outcomes regarding the model, and its current relatively widespread implementation.

An implementation analysis of a quality improvement project to reduce cesarean section in Brazilian private hospitals

BACKGROUND

Brazil has one of the highest prevalence of cesarean sections in the world. The private health system is responsible for carrying out most of these surgical procedures. A quality improvement project called Adequate Childbirth Project ("Projeto Parto Adequado"- PPA) was developed to identify models of care for labor and childbirth, which place value on vaginal birth and reduce the frequency of cesarean sections without a clinical indication. This research aims to evaluate the implementation of PPA in private hospitals in Brazil.

METHOD

Evaluative hospital-based survey, carried out in 2017, in 12 private hospitals, including 4,322 women. We used a Bayesian network strategy to develop a theoretical model for implementation analysis. We estimated and compared the degree of implementation of two major driving components of PPA-"Participation of women" and "Reorganization of care" - among the 12 hospitals and according to type of hospital (belonging to a health insurance company or not). To assess whether the degree of implementation was correlated with the rate of vaginal birth data we used the Bayesian Network and compared the difference between the group "Exposed to the PPA model of care" and the group "Standard of care model".

RESULTS

PPA had a low degree of implementation in both components "Reorganization of Care" (0.17 - 0.32) and "Participation of Women" (0.21 - 0.34). The combined implementation score was 0.39-0.64 and was higher in hospitals that belonged to a health insurance company. The vaginal birth rate was higher in hospitals with a higher degree of implementation of PPA.

CONCLUSION

The degree of implementation of PPA was low, which reflects the difficulties in changing childbirth care practices. Nevertheless, PPA increased vaginal birth rates in private hospitals with higher implementation scores. PPA is an ongoing quality improvement project and these results demonstrate the need for changes in the involvement of women and the care offered by the provider.

Incorporation, adaptation and rejection of obstetric practices during the implementation of the "Adequate Childbirth Program" in Brazilian private hospitals: a qualitative study

BACKGROUND

The "Adequate Childbirth Program" (PPA) is a quality improvement project that aims to reduce the high rates of unnecessary cesarean section in Brazilian private hospitals. This study aimed to analyze labor and childbirth care practices after the first phase of PPA implementation.

METHOD

This study uses a qualitative approach. Eight hospitals were selected. At each hospital, during the period of 5 (five) days, from July to October 2017, the research team conducted face to face interviews with doctors (n = 21) and nurses (n = 28), using semi-structured scripts. For the selection of professionals, the Snowball technique was used. The interviews were transcribed, and the data submitted to Thematic Content Analysis, using the MaxQda software.

RESULTS

The three analytical dimensions of the process of change in the care model: (1) Incorporation of care practices: understood as the practices that have been included since PPA implementation; (2) Adaptation of care practices: understood as practices carried out prior to PPA implementation, but which underwent modifications with the implementation of the project; (3) Rejection of care practices: understood as those practices that were abandoned or questioned whether or not they should be carried out by hospital professionals.

CONCLUSIONS

After the PPA, changes were made in hospitals and in the way, women were treated. Birth planning, prenatal hospital visits led by experts (for expecting mothers and their families), diet during labor, pharmacological analgesia for vaginal delivery, skin-to-skin contact, and breastfeeding in the first hour of life are all included. To better monitor labor and vaginal birth and to reduce CS without a clinical justification, hospitals adjusted their present practices. Finally, the professionals rejected the Kristeller maneuver since research has demonstrated that using it's harmful.

Caesarean delivery on maternal request: the perspective of the postpartum women

BACKGROUND

Caesarean delivery on maternal request (CDMR) is an increasing delivery option among women. As such, we aimed to understand the reasons that led pregnant women to request a caesarean delivery.

METHODS

A phenomenological study was conducted with semi-structured interviews, in a convenience sample, for women who had undergone a CDMR between March and June 2023, in a public reference university hospital in Campinas, Brazil. The interviews were recorded, transcribed and subjected to thematic analysis, supported by Nvivo®, and Reshape®.

RESULTS

We interviewed eighteen women between 21 and 43 years of age. The reasons for C-section as their choice were: 1) fear of labour pain, 2) fear for safety due to maternal or fetal risks, 3) traumatic previous birth experiences of the patient, family or friends 4) sense of control, and 5) lack of knowledge about the risks and benefits of C-section.

CONCLUSIONS

The perception of C-section as the painless and safest way to give birth, the movement of giving voice and respecting the autonomy of pregnant women, as well as the national regulation, contribute to the increased rates of surgical abdominal delivery under request. Cultural change concerning childbirth and better counseling could support a more adequate informed decision-making about delivery mode.

Fast Healthcare Interoperability Resources-Based Support System for Predicting Delivery Type: Model Development and Evaluation Study

BACKGROUND

The escalating prevalence of cesarean delivery globally poses significant health impacts on mothers and newborns. Despite this trend, the underlying reasons for increased cesarean delivery rates, which have risen to 36.3% in Portugal as of 2020, remain unclear. This study delves into these issues within the Portuguese health care context, where national efforts are underway to reduce cesarean delivery occurrences.

OBJECTIVE

This paper aims to introduce a machine learning, algorithm-based support system designed to assist clinical teams in identifying potentially unnecessary cesarean deliveries. Key objectives include developing clinical decision support systems for cesarean deliveries using interoperability standards, identifying predictive factors influencing delivery type, assessing the economic impact of implementing this tool, and comparing system outputs with clinicians' decisions.

METHODS

This study used retrospective data collected from 9 public Portuguese hospitals, encompassing maternal and fetal data and delivery methods from 2019 to 2020. We used various machine learning algorithms for model development, with light gradient-boosting machine (LightGBM) selected for deployment due to its efficiency. The model's performance was compared with clinician assessments through questionnaires. Additionally, an economic simulation was conducted to evaluate the financial impact on Portuguese public hospitals.

RESULTS

The deployed model, based on LightGBM, achieved an area under the receiver operating characteristic curve of 88%. In the trial deployment phase at a single hospital, 3.8% (123/3231) of cases triggered alarms for potentially unnecessary cesarean deliveries. Financial simulation results indicated potential benefits for 30% (15/48) of Portuguese public hospitals with the implementation of our tool. However, this study acknowledges biases in the model, such as combining different vaginal delivery types and focusing on potentially unwarranted cesarean deliveries.

CONCLUSIONS

This study presents a promising system capable of identifying potentially incorrect cesarean delivery decisions, with potentially positive implications for medical practice and health care economics. However, it also highlights the challenges and considerations necessary for real-world application, including further evaluation of clinical decision-making impacts and understanding the diverse reasons behind delivery type choices. This study underscores the need for careful implementation and further robust analysis to realize the full potential and real-world applicability of such clinical support systems.

Deliveries in Lebanon, the Country with the Highest Refugee Density in the World: A Descriptive Review

PURPOSE

The aim of this study is to analyze obstetrical and reproductive health parameters in Lebanon from 2015 until 2018 in the setting of the Syrian refugee influx in order to evaluate potential risks and provide a management plan to improve outcomes.

DESCRIPTION

Data from the Lebanese Ministry of Public Health (LMPH) on all obstetrical deliveries that occurred in Lebanon between 2015 and 2018 was screened and analyzed. Number and mode of delivery as well as maternal and neonatal outcomes were included. Joinpoint regression analysis was used for trends of selected parameters. Independent two-sample t-tests were used for comparisons.

ASSESSMENT

Women of non-Lebanese nationality residing in Lebanon had a significantly greater number of total deliveries (p-value < 0.001), vaginal deliveries (p-value = 0.002), cesarean sections (p-value = 0.02). When looking at delivery trends from 2015 to 2018, Lebanese women had a significant decrease in total number of deliveries (p-value < 0.001) and vaginal deliveries (p-value < 0.001).

CONCLUSION

Total number of deliveries and cesarean sections is on the rise in Lebanon. Cesarean section practice should be audited by the LMPH and the Lebanese Order of Physicians (LOP). Local and international agencies should prioritize the implementation and management of family planning facilities in refugee hosting countries.

Continuity of Clinician Type and Intrapartum Experiences During the Perinatal Period in California

INTRODUCTION

Continuity of care with an individual clinician is associated with increased satisfaction and better outcomes. Continuity of clinician type (ie, obstetrician-gynecologist or midwife) may also impact care experiences; however, it is unknown how common it is to experience discontinuity of clinician type and what its implications are for the birth experience. We aimed to identify characteristics associated with having a different clinician type for prenatal care than for birth and to compare intrapartum experiences by continuity of clinician type.

METHODS

For this cross-sectional study, data were from the 2017 Listening to Mothers in California survey. The analytic sample was limited to individuals with vaginal births who had midwifery or obstetrician-gynecologist prenatal care (N = 1384). Bivariate and multivariate analysis examined characteristics of individuals by continuity of clinician type. We then examined associations of clinician type continuity with intrapartum care experiences.

RESULTS

Overall, 74.4% of individuals had the same type of clinician for prenatal care and birth. Of individuals with midwifery prenatal care, 45.1% had a different birth clinician type, whereas 23.5% of individuals who had obstetrician-gynecologist prenatal care had a different birth clinician type. Continuity of clinician type was positively associated with having had a choice of perinatal care clinician. There were no statistically significant associations between clinician type continuity and intrapartum care experiences.

DISCUSSION

Findings suggest individuals with midwifery prenatal care frequently have a different type of clinician attend their birth, even among those with vaginal births. Further research should examine the impact of multiple dimensions of continuity of care on perinatal care quality.

From evidence to tailored decision-making: a qualitative research of barriers and facilitating factors for the implementation of non-clinical interventions to reduce unnecessary caesarean section in Romania

OBJECTIVE

To improve understanding of the drivers of the increased caesarean section (CS) rate in Romania and to identify interventions to reverse this trend, as well as barriers and facilitators.

DESIGN

A formative research study was conducted in Romania between November 2019 and February 2020 by means of in-depth interviews and focus-group discussions. Romanian decision-makers and high-level obstetricians preselected seven non-clinical interventions for consideration. Thematic content analysis was carried out.

PARTICIPANTS

88 women and 26 healthcare providers and administrators.

SETTINGS

Counties with higher and lower CS rates were selected for this research-namely Argeș, Bistrița-Năsăud, Brașov, Ialomița, Iași, Ilfov, Dolj and the capital city of București (Bucharest).

RESULTS

Women wanted information, education and support. Obstetricians feared malpractice lawsuits; this was identified as a key reason for performing CSs. Most obstetrics and gynaecology physicians would oppose policies of mandatory second opinions, financial measures to equalise payments for vaginal and CS births and goal setting for CS rates. In-service training was identified as a need by obstetricians, midwives and nurses. In addition, relevant structural constraints were identified: perceived lower quality of care for vaginal birth, a lack of obstetricians with expertise in managing complicated vaginal births, a lack of anaesthesiologists and midwives, and family doctors not providing antenatal care. Finally, women expressed the need to ensure their rights to dignified and respectful healthcare through pregnancy and childbirth.

CONCLUSION

Consideration of the views, values and preferences of all stakeholders in a multifaceted action tailored to Romanian determinants is critical to address relevant determinants to reduce unnecessary CSs. Further studies should assess the effect of multifaceted interventions.

Implementing the QUALI-DEC project in Argentina, Burkina Faso, Thailand and Viet Nam: a process delineation and theory-driven process evaluation protocol

The project 'Quality Decision-making by women and providers' (QUALI-DEC) combines four non-clinical interventions to promote informed decision-making surrounding mode of birth, improve women's birth experiences, and reduce caesarean sections among low-risk women. QUALI-DEC is currently being implemented in 32 healthcare facilities across Argentina, Burkina Faso, Thailand, and Viet Nam. In this paper, we detail implementation processes and the planned process evaluation, which aims to assess how and for whom QUALI-DEC worked, the mechanisms of change and their interactions with context and setting; adaptations to intervention and implementation strategies, feasibility of scaling-up, and cost-effectiveness of the intervention. We developed a project theory of change illustrating how QUALI-DEC might lead to impact. The theory of change, together with on the ground observations of implementation processes, guided the process evaluation strategy including what research questions and perspectives to prioritise. Main data sources will include: 1) regular monitoring visits in healthcare facilities, 2) quantitative process and output indicators, 3) a before and after cross-sectional survey among post-partum women, 4) qualitative interviews with all opinion leaders, and 5) qualitative interviews with postpartum women and health workers in two healthcare facilities per country, as part of a case study approach. We foresee that the QUALI-DEC process evaluation will generate valuable information that will improve interpretation of the effectiveness evaluation. At the policy level, we anticipate that important lessons and methodological insights will be drawn, with application to other settings and stakeholders looking to implement complex interventions aiming to improve maternal and newborn health and wellbeing.Trial registration: ISRCTN67214403.

Mobile Prenatal Education and Its Impact on Reducing Adverse Pregnancy Outcomes: Retrospective Real-World Study

BACKGROUND

Pregnancy is a pivotal phase in a woman's life, demanding special attention to ensure maternal and fetal health. Prenatal education plays a vital role in promoting healthy pregnancies and reducing adverse outcomes for pregnant women. Mobile prenatal education programs have gained traction due to their accessibility and timeliness, especially in light of finite health care resources and the constraints imposed by the COVID-19 pandemic.

OBJECTIVE

This study aims to develop and evaluate the effectiveness of a mobile-based prenatal education program in improving pregnancy outcomes.

METHODS

We developed a mobile-based prenatal education curriculum in collaboration with a multidisciplinary maternal care team from Peking Union Medical College Hospital (PUMCH) in Beijing, China. Data were retrospectively collected from 1941 pregnant women who had registered for the PUMCH mobile prenatal education program and subsequently delivered at PUMCH between May 2021 and August 2022. The study compared pregnancy outcomes between the completing group, which were pregnant women who had completed at least 1 course, and the noncompleting group. We also analyzed differences among course topics within the completing group and assessed course topic popularity among pregnant women.

RESULTS

The PUMCH mobile prenatal education curriculum consists of 436 courses across 9 topics. Out of the participants, a total of 1521 did not complete any courses, while 420 completed at least 1 course. Compared with the noncompleting group, pregnant women who completed courses exhibited a significant reduction in the risk of gestational diabetes mellitus, induced abortion, postpartum infection, fetal intrauterine distress, and neonatal malformation. Among those in the completing group, a total of 86% (361/420) started course completion during the first and second trimesters. Furthermore, completing courses related to topics of pregnancy psychology and pregnancy nutrition was associated with reduced risks of premature rupture of membranes and small for gestational age infants, respectively. Pregnancy psychology and postpartum recovery were the preferred topics among pregnant women.

CONCLUSIONS

The study demonstrates the potential of mobile-based prenatal education programs in improving pregnancy outcomes and supporting health care providers in delivering effective prenatal education. The rise of mobile prenatal education presents an opportunity to improve maternal and child health outcomes. Further research and broader implementation of such programs are warranted to continually improve maternal and child health.

Fostering childbirth education on upright positions and mobility during labor in nulliparous women

BACKGROUND

Upright labor positions and movement during labor have a positive effect on childbirth, yet the predominant labor positions are still horizontal. Therefore, it is important to explore how it is possible to improve childbirth education, particularly its instructional design, to strengthen women's self-efficacy toward the use of upright positions and mobility during labor. The aim of the study was to evaluate the impact of an instructional approach based on a cognitive engagement ICAP (Interactive, Constructive, Active, Passive) framework on the development of knowledge, attitudes, and self-efficacy expectations toward upright positions and mobility during labor.

METHODS

A prospective quasi-experimental study was conducted among nulliparous women from the ultra-orthodox Jewish community (n = 74). While the control group (n = 34) participated in routine childbirth education, the intervention group (n = 36) learned with childbirth education that included interactive and constructive cognitive engagement activities. Participants in both groups completed a set of questionnaires regarding knowledge, attitudes, and self-efficacy.

RESULTS

The post-test analysis revealed that women in the intervention group compared to the control group gained significantly higher knowledge scores (p < 0.05), more positive attitudes (p < 0.001), and stronger self-efficacy expectations toward upright positions and mobility during labor (p < 0.01).

CONCLUSIONS

The findings suggest that by fostering women's cognitive engagement levels during childbirth education toward the interactive and constructive modes of the ICAP framework, women's self-efficacy to move during labor and to use upright positions can be induced. These results can serve as a foundation to improve the overall effectiveness of childbirth instruction.

TRIAL REGISTRATION

The study was registered retrospectively.

Making the cut on caesarean section: a logistic regression analysis on factors favouring caesarean sections without medical indication in comparison to spontaneous vaginal birth

BACKGROUND

In the absence of medical necessity, opting for caesarean sections exposes mothers and neonates to increased risks of enduring long-term health problems and mortality. This ultimately results in greater economic burden when compared to the outcomes of spontaneous vaginal births. In Switzerland around 33% of all births are by caesarean section. However, the rate of caesarean sections without medical indication is still unknown. Therefore, we devise an identification strategy to differentiate caesarean sections without medical indication using routine data. In addition, we aim to categorize the influencing factors for women who undergo spontaneous vaginal births as opposed to those with caesarean sections without medical indication.

METHOD

We use Swiss Federal Statistics data including 98.3% of all women giving birth from 2014 to 2018. To determine non-medically indicated caesarean sections in our dataset, we base our identification strategy on diagnosis-related groups, diagnosis codes, and procedure classifications. Subsequently, we compare characteristics of women who give birth by non-medically CS and external factors such as the density of practicing midwives to women with spontaneous vaginal birth. Logistic regression analysis measures the effect of factors, such as age, insurance class, income, or density of practicing midwives on non-medically indicated caesarean sections.

RESULTS

Around 8% of all Swiss caesarean sections have no medical indication. The regression analysis shows that higher age, supplemental insurance, higher income, and living in urban areas are associated with non-medically indicated caesarean sections, whereas a higher density of midwives decreases the likelihood of caesarean sections without medical indication.

CONCLUSIONS

By identifying non-medically indicated caesarean sections using routine data, it becomes feasible to gain insights into the characteristics of impacted mothers as well as the external factors involved. Illustrating these results, our recommendation is to revise the incentive policies directed towards healthcare professionals. Among others, future research may investigate the potential of midwife-assisted pregnancy programs on strengthening spontaneous vaginal births in absence of medical complications.

Association of Maternal Comorbidity Burden With Cesarean Birth Rate Among Nulliparous, Term, Singleton, Vertex Pregnancies

IMPORTANCE

Cesarean birth rate among nulliparous, term, singleton, vertex (NTSV) pregnancies is a standard quality measure in obstetrical care. There are limited data on how the number and type of preexisting conditions affect mode of delivery among primigravidae, and it is also uncertain how maternal comorbidity burden differs across racial and ethnic groups and whether this helps to explain disparities in the NTSV cesarean birth rate.

OBJECTIVE

To determine the association between obstetric comorbidity index (OB-CMI) score and cesarean delivery among NTSV pregnancies and to evaluate whether disparities in mode of delivery exist based on race and ethnicity group after adjusting for covariate factors.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study of deliveries between January 2019 and December 2021 took place across 7 hospitals within a large academic health system in New York and included all NTSV pregnancies identified in the electronic medical record system. Exclusion criteria were fetal demise and contraindication to labor.

EXPOSURE

The OB-CMI score. Covariate factors assessed included race and ethnicity group (American Indian or Alaska Native, Asian or Pacific Islander, Hispanic, non-Hispanic Black, non-Hispanic White, other or multiracial, and declined or unknown), public health insurance, and preferred language.

MAIN OUTCOME AND MEASURES

Cesarean delivery.

RESULTS

A total of 30 253 patients (mean [SD] age, 29.8 [5.4] years; 100% female) were included. Non-Hispanic White patients constituted the largest race and ethnicity group (43.7%), followed by Hispanic patients (16.2%), Asian or Pacific Islander patients (14.6%), and non-Hispanic Black patients (12.2%). The overall NTSV cesarean birth rate was 28.5% (n = 8632); the rate increased from 22.1% among patients with an OB-CMI score of 0 to greater than 55.0% when OB-CMI scores were 7 or higher. On multivariable mixed-effects logistic regression modeling, there was a statistically significant association between OB-CMI score group and cesarean delivery; each successive OB-CMI score group had an increased risk. Patients with an OB-CMI score of 4 or higher had more than 3 times greater odds of a cesarean birth (adjusted odds ratio, 3.14; 95% CI, 2.90-3.40) than those with an OB-CMI score of 0. Compared with non-Hispanic White patients, nearly all other race and ethnicity groups were at increased risk for cesarean delivery, and non-Hispanic Black patients were at highest risk (adjusted odds ratio, 1.43; 95% CI, 1.31-1.55).

CONCLUSIONS AND RELEVANCE

In this cross-sectional study of patients with NTSV pregnancies, OB-CMI score was positively associated with cesarean birth. Racial and ethnic disparities in this metric were observed. Although differences in the prevalence of preexisting conditions were seen across groups, this did not fully explain variation in cesarean delivery rates, suggesting that unmeasured clinical or nonclinical factors may have influenced the outcome.

Educational interventions targeting pregnant women to optimise the use of caesarean section: What are the essential elements? A qualitative comparative analysis

BACKGROUND

Caesarean section (CS) rates are increasing globally, posing risks to women and babies. To reduce CS, educational interventions targeting pregnant women have been implemented globally, however, their effectiveness is varied. To optimise benefits of these interventions, it is important to understand which intervention components influence success. In this study, we aimed to identify essential intervention components that lead to successful implementation of interventions focusing on pregnant women to optimise CS use.

METHODS

We re-analysed existing systematic reviews that were used to develop and update WHO guidelines on non-clinical interventions to optimise CS. To identify if certain combinations of intervention components (e.g., how the intervention was delivered, and contextual characteristics) are associated with successful implementation, we conducted a Qualitative Comparative Analysis (QCA). We defined successful interventions as interventions that were able to reduce CS rates. We included 36 papers, comprising 17 CS intervention studies and an additional 19 sibling studies (e.g., secondary analyses, process evaluations) reporting on these interventions to identify intervention components. We conducted QCA in six stages: 1) Identifying conditions and calibrating the data; 2) Constructing truth tables, 3) Checking quality of truth tables; 4) Identifying parsimonious configurations through Boolean minimization; 5) Checking quality of the solution; 6) Interpretation of solutions. We used existing published qualitative evidence synthesis to develop potential theories driving intervention success.

RESULTS

We found successful interventions were those that leveraged social or peer support through group-based intervention delivery, provided communication materials to women, encouraged emotional support by partner or family participation, and gave women opportunities to interact with health providers. Unsuccessful interventions were characterised by the absence of at least two of these components.

CONCLUSION

We identified four key essential intervention components which can lead to successful interventions targeting women to reduce CS. These four components are 1) group-based delivery, 2) provision of IEC materials, 3) partner or family member involvement, and 4) opportunity for women to interact with health providers. Maternal health services and hospitals aiming to better prepare women for vaginal birth and reduce CS can consider including the identified components to optimise health and well-being benefits for the woman and baby.

Perinatal Outcomes of Pregnancy in Women with Scarred Uteri

Objective

Uterine scarring is risky for the pregnancy and is closely associated with adverse pregnancy outcomes. Here, we investigated risk factors and associated perinatal outcomes in singleton pregnant women with uterine scars.

Methods

This retrospective cohort study was conducted on singleton pregnant women who delivered at the West China Second University Hospital between January 1, 2021, and December 31, 2021.

Results

The control group included 13,433 cases without uterine scars. The study group involved 2397 cases with one previous cesarean delivery (PCD), 163 cases with two PCDs, 12 cases with three PCDs, and 184 cases with non-cesarean uterine scars. The study group had a significantly higher incidence of placenta previa (6.4%), placenta percreta (5.3%), preterm delivery (10.3%), postpartum hemorrhage (3.4%), uterine rupture (9.4%), hysterectomy (0.18%), and bladder injury (0.4%) when compared with the control group (P <0.05). The scarred uterus cases with 1, 2, or 3 PCDs had significantly different complications, with the higher PCD frequency correlating with increased rates of placenta previa, placenta percreta, postpartum hemorrhage, uterine rupture, and uterine resection. Moreover, the hospitalization time, cesarean operation time, and intrapartum bleeding in the current pregnancy significantly increased with increasing PCD frequency (P <0.05). Analysis of the association between the duration of the interval between PCD and re-pregnancy and pregnancy complication revealed that the incidence of pernicious placenta previa was statistically higher in cases with intervals of <2 years or ≥5 years (4.7%) than in cases with 2 years ≤ interval time <5 years (2.5%) (P <0.05).

Conclusion

Pregnancies with uterine scars may experience higher rates of adverse perinatal outcomes. This calls for increased observation during pregnancy and delivery to reduce maternal and fetal complications.

Cesarean section rates according to the Robson Classification and its association with adequacy levels of prenatal care: a cross-sectional hospital-based study in Brazil

BACKGROUND

The rate of Cesarean section (CS) deliveries has been increasing worldwide for decades. Brazil exhibits high rates of patient-requested CS deliveries. Prenatal care is essential for reducing and preventing maternal and child morbidity and mortality, ensuring women's health and well-being. The aim of this study was to verify the association between the level of prenatal care, as measured by the Kotelchuck (APNCU - Adequacy of the prenatal care utilization) index and CS rates.

METHODS

We conducted a cross-sectional study based on data from routine hospital digital records and federal public health system databases (2014-2017). We performed descriptive analyses, prepared Robson Classification Report tables, and estimated the CS rate for the relevant Robson groups across distinct levels of prenatal care. Our analysis also considered the payment source for each childbirth - either public healthcare or private health insurers - and maternal sociodemographic data.

RESULTS

CS rate by level of access to prenatal care was 80.0% for no care, 45.2% for inadequate, 44.2% for intermediate, 43.0% for adequate, and 50.5% for the adequate plus category. No statistically significant associations were found between the adequacy of prenatal care and the rate of cesarean sections in any of the most relevant Robson groups, across both public (n = 7,359) and private healthcare (n = 1,551) deliveries.

CONCLUSION

Access to prenatal care, according to the trimester in which prenatal care was initiated and the number of prenatal visits, was not associated with the cesarean section rate, suggesting that factors that assess the quality of prenatal care, not simply adequacy of access, should be investigated.

A modular systematic review of antenatal interventions targeting modifiable environmental exposures in improving low birth weight

BACKGROUND

Low birth weight (LBW) increases the risk of short- and long-term morbidity and mortality from early life to adulthood. Despite research effort to improve birth outcomes the progress has been slow.

OBJECTIVE

This systematic search and review of English language scientific literature on clinical trials aimed to compare the efficacy antenatal interventions to reduce environmental exposures including a reduction of toxins exposure, and improving sanitation, hygiene, and health-seeking behaviors, which target pregnant women to improve birth outcomes.

METHODS

We performed eight systematic searches in MEDLINE (OvidSP), Embase (OvidSP), Cochrane Database of Systematic Reviews (Wiley Cochrane Library), Cochrane Central Register of Controlled Trials (Wiley Cochrane Library), CINAHL Complete (EbscoHOST) between 17 March 2020 and 26 May 2020.

RESULTS

Four documents identified describe interventions to reduce indoor air pollution: two randomised controlled trials (RCTs), one systematic review and meta-analysis (SRMA) on preventative antihelminth treatment and one RCT on antenatal counselling against unnecessary caesarean section. Based on the published literature, interventions to reduce indoor air pollution (LBW: RR: 0.90 [0.56, 1.44], PTB: OR: 2.37 [1.11, 5.07]) or preventative antihelminth treatment (LBW: RR: 1.00 [0.79, 1.27], PTB: RR: 0.88 [0.43, 1.78]) are not likely to reduce the risk of LBW or Preterm birth (PTB). Data is insufficient on antenatal counselling against caesarian-sections. For other interventions, there is lack of published research data from RCTs.

CONCLUSIONS

We conclude that there is a paucity of evidence from RCT on interventions that modify environmental risk factors during pregnancy to potentially improve birth outcomes. Magic bullets approach might not work and that it would be important to study the effect of the broader interventions, particularly in LMIC settings. Global interdisciplinary action to reduce harmful environmental exposures, is likely to help to reach global targets for LBW reduction and sustainably improve long-term population health.

The evolution of the labor curve and its implications for clinical practice: the relationship between cervical dilation, station, and time during labor

The assessment of labor progress is germane to every woman in labor. Two labor disorders-arrest of dilation and arrest of descent-are the primary indications for surgery in close to 50% of all intrapartum cesarean deliveries and are often contributing indications for cesarean deliveries for fetal heart rate abnormalities. Beginning in 1954, the assessment of labor progress was transformed by Friedman. He published a series of seminal works describing the relationship between cervical dilation, station of the presenting part, and time. He proposed nomenclature for the classification of labor disorders. Generations of obstetricians used this terminology and normal labor curves to determine expected rates of dilation and fetal descent and to decide when intervention was required. The analysis of labor progress presents many mathematical challenges. Clinical measurements of dilation and station are imprecise and prone to variation, especially for inexperienced observers. Many interrelated factors influence how the cervix dilates and how the fetus descends. There is substantial variability in when data collection begins and in the frequency of examinations. Statistical methods to account for these issues have advanced considerably in recent decades. In parallel, there is growing recognition among clinicians of the limitations of using time alone to assess progress in cervical dilation in labor. There is wide variation in the patterns of dilation over time and most labors do not follow an average dilation curve. Reliable assessment of labor progression is important because uncertainty leads to both over-use and under-use of cesarean delivery and neither of these extremes are desirable. This review traces the evolution of labor curves, describes how limitations are being addressed to reduce uncertainty and to improve the assessment of labor progression using modern statistical techniques and multi-dimensional data, and discusses the implications for obstetrical practice.

Women's and health providers' perceptions of companionship during labor and childbirth: a formative study for the implementation of WHO companionship model in Burkina Faso

INTRODUCTION

A key component of achieving respectful maternal and newborn care is labor companionship. Despite important health benefits for the woman and baby, there are critical gaps in implementing labor companionship for all women globally. The paper aims to present the perceptions and experiences of pregnant women, postpartum women, and health care providers regarding companionship during labor and childbirth, and to identify barriers and facilitating factors to the implementation of labor companionship in Burkina Faso.

METHODS

This is a formative study to inform the "Appropriate use of cesarean section through QUALIty DECision-making by women and providers" (QUALI-DEC) study, to design, adapt and implement a strategy to optimize the use of the cesarean section, including labor companionship. We use in-depth interviews (women, potential companions, and health workers) and health facility readiness assessments in eight hospitals across Burkina Faso. We use a thematic analysis approach for interviews, and narrative summaries to describe facility readiness assessment.

RESULTS

In all, 77 qualitative interviews and eight readiness assessments are included in this analysis. The findings showed that all participants acknowledged an existing traditional companionship model, which allowed companions to support women only in the hospital waiting room and post-natal room. Despite recognizing clear benefits, participants were not familiar with companionship during labor and childbirth in the hospital as recommended by WHO. Key barriers to implementing companionship throughout labor and birth include limited space in labor and delivery wards, no private rooms for women, hospital rules preventing companionship, and social norms preventing the choice of a companion by the woman.

CONCLUSION

Labor companionship was considered highly acceptable in Burkina Faso, but more work is needed to adapt to the hospital environment. Revisions to hospital policies to allow companions during labor and childbirth are needed as well as changes to provide private space for women. Training potential companions about their roles and encouraging women's rights to choose their companions may help to facilitate effective implementation.

Impact of new labor management guidelines on Cesarean rates among low-risk births at New York City hospitals: A controlled interrupted time series analysis

PURPOSE

To examine the impact of the American College of Obstetricians and Gynecologists and Society for Maternal-Fetal Medicine (ACOG-SMFM) 2014 recommendations for preventing unnecessary primary Cesareans.

METHODS

In a population-based cohort of births in New York City from 2012 to 2016, we used controlled interrupted time series analyses to estimate changes in age-standardized Cesarean rates among nulliparous, term, singleton vertex (NTSV) deliveries.

RESULTS

Among 192,405 NTSV births across 40 hospitals, the age-standardized NTSV Cesarean rate decreased after the ACOG-SMFM recommendations from 25.8% to 24.0% (Risk ratio [RR]: 0.93; 95% CI 0.89, 0.97), with no change in the control series. Decreases were observed among non-Hispanic White women (RR: 0.89; 95% CI 0.82, 0.97), but not among non-Hispanic Black women (RR: 0.97; 95% CI 0.88, 1.07), Asian/Pacific Islanders (RR: 1.01; 95% CI 0.91, 1.12), or Hispanic women (RR: 0.94; 95% CI 0.86, 1.02). Similar patterns were observed at teaching hospitals, with no change at nonteaching hospitals.

CONCLUSIONS

While low-risk Cesarean rates may be modifiable through changes in labor management, additional research, and interventions to address Cesarean disparities, are needed.

Women's voice on changes in childbirth care practices: a qualitative approach to women's experiences in Brazilian private hospitals participating in the Adequate Childbirth Project

BACKGROUND

In Brazil, childbirth practices are strongly marked by surgical events and particularly in the private sector cesarean sections reach rates above 80%. The National Supplementary Health Agency proposed the Adequate Childbirth Project (PPA), a quality improvement project developed at Brazilian hospitals with the aim of changing the current model of childbirth care and reducing unnecessary cesarean sections. The objective of this study is to assess how the participation of women in the process of improving quality childbirth care occurred in two hospitals participating in the PPA.

METHOD

Qualitative study, based on interviews with 102 women attended at two hospitals that took part in the first and second stages of the "Healthy Birth", an evaluative hospital-based research, conducted in 2017-2018, that assessed the degree of implementation and the effects of PPA. After thematic content analysis, supported by MaxQda software, three categories emerged: (1) how women gathered knowledge about the PPA, (2) how women perceived it, and (3) which are their suggestions for the PPA improvement.

RESULTS

The PPA was unknown to most women before delivery. A polysemy of terms, including adequate childbirth, promotes recognition of the "new" model of care. Visits to the maternity hospital and antenatal care groups for pregnant women are opportunities for contacts that change the perception of what childbirth can be. Women have expectations of a relationship with maternity that is not limited to the moment of delivery. The listening channels established between hospitals and women are fragile and not systematized. By increasing the supply of listening spaces, one can also increase the request to leave their suggestions and contributions, and thus gain more allies in improving the project. Women are not yet included as PPA agents and their voices are silenced.

CONCLUSIONS

Women's participation to improve childbirth care is relevant and necessary. The women's voice in the PPA is still incipient, and maternity hospitals and health plan operators should create strategies to insert and engage them. Women's voices should be listened to not only during but also before and after childbirth.

Interventions targeting healthcare providers to optimise use of caesarean section: a qualitative comparative analysis to identify important intervention features

BACKGROUND

Rapid increases in caesarean section (CS) rates have been observed globally; however, CS rates exceeding 15% at a population-level have limited benefits for women and babies. Many interventions targeting healthcare providers have been developed to optimise use of CS, typically aiming to improve and monitor clinical decision-making. However, interventions are often complex, and effectiveness is varied. Understanding intervention and implementation features that likely lead to optimised CS use is important to optimise benefits. The aim of this study was to identify important components that lead to successful interventions to optimise CS, focusing on interventions targeting healthcare providers.  METHODS: We used Qualitative Comparative Analysis (QCA) to identify if certain combination of important intervention features (e.g. type of intervention, contextual characteristics, and how the intervention was delivered) are associated with a successful intervention as reflected in a reduction of CS. We included 21 intervention studies targeting healthcare providers to reduce CS, comprising of 34 papers reporting on these interventions. To develop potential theories driving intervention success, we used existing published qualitative evidence syntheses on healthcare providers' perspectives and experiences of interventions targeted at them to reduce CS.

RESULTS

We identified five important components that trigger successful interventions targeting healthcare providers: 1) training to improve providers' knowledge and skills, 2) active dissemination of CS indications, 3) actionable recommendations, 4) multidisciplinary collaboration, and 5) providers' willingness to change. Importantly, when one or more of these components are absent, dictated nature of intervention, where providers are enforced to adhere to the intervention, is needed to prompt successful interventions. Unsuccessful interventions were characterised by the absence of these components.

CONCLUSION

We identified five important intervention components and combinations of intervention components which can lead to successful interventions targeting healthcare providers to optimise CS use. Health facility managers, researchers, and policy-makers aiming to improve providers' clinical decision making and reduce CS may consider including the identified components to optimise benefits.

Caesarean Section on Maternal Request-Ethical and Juridic Issues: A Narrative Review

In recent decades, the rate of caesarean deliveries has increased worldwide. The reasons for this trend are still largely misunderstood and controversial among researchers. The decision often depends on the obstetrician, his beliefs and experience, the characteristics of the patients, the hospital environment and its internal protocols, the increasing use of induction of labor, the medico-legal implications, and, finally, the mother's ability to request delivery by caesarean section without medical indication. This review aims to describe the reasons behind the increasing demand for caesarean sections by patients (CDMR) and strategies aimed at reducing caesarean section rates and educating women about the risks and benefits of CS.

Robson's Ten Group Classification System to Evaluate Cesarean Section Rates in Honduras: The Relevance of Labor Induction

OBJECTIVE

 To use the Robson Ten Group Classification (RTGC) to analyze cesarean section (CS) rates in a Honduran maternity hospital, with focus in groups that consider induction of labor.

METHODS

 Cross-sectional study. Women admitted for childbirth (August 2017 to October 2018) were classified according to the RTGC. The CS rate for each group and the contribution to the overall CS rate was calculated, with further analyses of the induction of labor among term primiparous (group 2a), term multiparous (group 4a), and cases with one previous CS (group 5.1).

RESULTS

 A total of 4,356 women were considered, with an overall CS rate of 26.1%. Group 3 was the largest group, with 38.6% (1,682/4,356) of the cases, followed by Group 1, with 30.8% (1,342/4,356), and Group 5, with 10.3% (450/4,356). Considering the contribution to overall CS rates per group, Group 5 contributed with 30.4% (345/1,136) of the CSs and within this group, 286/345 (82.9%) had 1 previous CS, with a CS rate > 70%. Groups 1 and 3, with 26.6% (291/1,136) and 13.5% (153/1,136), respectively, were the second and third larger contributors to the CS rate. Groups 2a and 4a had high induction success, with low CS rates (18.4 and 16.9%, respectively).

CONCLUSION

 The RTGC is a useful tool to assess CS rates in different healthcare facilities. Groups 5, 1, and 3 were the main contributors to the CS rate, and groups 2 and 4 showed the impact and importance of induction of labor. These findings may support future interventions to reduce unnecessary CS, especially among primiparous and in women with previous CS.

Childbirth experience, risk of PTSD and obstetric and neonatal outcomes according to antenatal classes attendance

Antenatal classes have evolved considerably and include now a discussion of the parents' birth plan. Respecting this plan normally results in a better childbirth experience, an important protective factor of post-traumatic stress disorder following childbirth (PTSD-FC). Antenatal class attendance may thus be associated with lower PTSD-FC rates. This cross-sectional study took place at a Swiss university hospital. All primiparous women who gave birth to singletons from 2018 to 2020 were invited to answer self-reported questionnaires. Data for childbirth experience, symptoms of PTSD-FC, neonatal, and obstetrical outcomes were compared between women who attended (AC) or not (NAC) antenatal classes. A total of 794/2876 (27.6%) women completed the online questionnaire. Antenatal class attendance was associated with a poorer childbirth experience (p = 0.03). When taking into account other significant predictors of childbirth experience, only induction of labor, use of forceps, emergency caesarean, and civil status remained in the final model of regression. Intrusion symptoms were more frequent in NAC group (M = 1.63 versus M = 1.11, p = 0.02). Antenatal class attendance, forceps, emergency caesarean, and hospitalisation in NICU remained significant predictors of intrusions for PTSD-FC. Use of epidural, obstetrical, and neonatal outcomes were similar for AC and NAC.

Obstetric and perinatal outcomes in parturients with active SARS-CoV-2 infection during labor and delivery: a retrospective cohort study

BACKGROUND

The COVID-19 pandemic is an ongoing global healthcare crisis that negatively affects pregnant women. Although patients with an acute infection during pregnancy have been widely studied, information regarding labor and delivery while infected is sparse. The aim of the study was to ascertain maternal, obstetrical, and perinatal outcomes of women who gave birth while infected with SARS-CoV-2.

METHODS

Patients diagnosed with COVID-19 during pregnancy at a tertiary medical center in 4/20-2/21 were identified by a retrospective database search. Those with an active intrapartum SARS-CoV-2 infection were compared with those who recovered at least 10 days before labor and delivery.

RESULTS

Of the 176 women included in the study, 84 had a SARS-CoV-2 infection at the time of delivery and 92 had recovered from the infection. There was no statistically significant between-group difference in mean gestational age at delivery (39 weeks for both, p = 0.71) and overall rate of cesarean delivery (26.2% vs 17.4%, respectively, p = 0.35) or non-elective cesarean delivery (10.71% vs 4.34%, respectively, p = 0.48). In the active-infection group, the rate of severe disease was 2.4%, and of critical disease (with intensive care unit admission, mechanical ventilation, and ECMO), 3.6%, compared to zero for both in the recovered group. No differences were found between the groups in adverse perinatal outcomes.

CONCLUSION

Delivery is safe and feasible in women with active SARS-CoV-2 infection. Nevertheless, we found a non-significant trend for more severe disease and for cesarean delivery and urgent cesarean delivery (for COVID-19-related indications) in women with an intrapartum SARS-CoV-2 infection.

Has the cesarean epidemic in Czechia been reversed despite fertility postponement?

Background

Although the percentage of cesarean sections (CS) in Czechia is below the average of that of other developed countries (23.6%), it still exceeds WHO recommendations (15%). The first aim of the study is to examine the association between a CS birth and the main health factors and sociodemographic characteristics involved, while the second aim is to examine recent trends in the CS rate in Czechia. 

Methods

Anonymized data on all mothers in Czechia for 2018 taken from the National Register of Expectant Mothers was employed. The risk of cesarean delivery for the observed factors was tested via the construction of a binary logistic regression model that allowed for adjustments for all the other covariates in the model.

Results

Despite all the covariates being found to be statistically significant, it was determined that health factors represented a higher risk of a CS than sociodemographic characteristics. A previous CS was found to increase the risk of its recurrence by 33 times (OR = 32.96, 95% CI 30.95–35.11, p<0.001). The breech position increased the risk of CS by 31 times (OR = 31.03, 95% CI 28.14–34.29, p<0.001). A multiple pregnancy increased the odds of CS six-fold and the use of ART 1.8-fold. Mothers who suffered from diabetes before pregnancy were found to be twice as likely to give birth via CS (OR = 2.14, 95% CI 1.76–2.60, p<0.001), while mothers with gestational diabetes had just 23% higher odds of a CS birth (OR = 1.23, 95% CI 1.16–1.31, p<0.001). Mothers who suffered from hypertension gave birth via CS twice as often as did mothers without such complications (OR = 2.01, 95% CI 1.86–2.21, p<0.001).

Conclusions

The increasing age of mothers, a significant risk factor for a CS, was found to be independent of other health factors. Accordingly, delayed childbearing is thought to be associated with the increase in the CS rate in Czechia. However, since other factors come into play, further research is needed to assess whether the recent slight decline in the CS rate is not merely a temporal trend.

Duration of second stage of labor and factors associated with prolonged second stage: A national population-based study in France

OBJECTIVES

Prolonged second stage of labor could be associated with an increase in maternal and neonatal morbidity. However, in France, no consensual definition of prolonged 2nd stage of labor exists and therefore factors associated with prolonged second stage have not yet been studied. From national population-based data, we aimed at defining the prolonged 2nd stage of labor in France and identifying its associated factors for women with epidural.

STUDY DESIGN

From the French national perinatal survey of 2016, we included all women who reached 2nd stage of labor and delivered at term of a singleton infant in cephalic presentation. We studied the distribution of the duration of the 2nd stage according to parity and defined prolonged 2nd stage as the 90th percentile. Among women with epidural, factors associated with a prolonged 2nd stage of labor were then explored by univariate and multilevel multivariable analysis, to take the cluster effect into account. The proportional change of variance was estimated for each multivariate model.

RESULTS

Among the 8154 women included, 3574 were nulliparous and 4580 multiparous. Prolonged second stage was defined as a duration of more than 89.6 min and 30.6 min for nulliparous and multiparous women without epidural; and respectively 185.7 min and 120.1 min for women with epidural analgesia. The factors associated with prolonged 2nd stage of labor were respectively for nulliparous and multiparous women, macrosomia (aOR 1.74 [1.03-2.94] and ORa 2.52 [1.69-3.76]), prenatal preparation classes (aOR 1.47 [1.04-2.08] and aOR 1.56 [1.21-2.01]), a prolonged 1st stage (aOR 1.47 [1.14-1.87] and aOR 1.52 [1.19-1.95]) and delivery in a public maternity unit (aOR 2.68 [1.50-4.78] and aOR 3.12 [1.88-5.17]). Women's characteristics accounted for 3.4% of the variance and maternity organizational characteristics for 26.1%.

CONCLUSION

In France, prolonged 2nd stage of labor can be defined as a 2nd stage exceeding 3 h in nulliparous and 2 h in multiparous women with epidural analgesia. The identification of its associated factors allows determining a target population of women at risk of prolonged 2nd stage and improve their 2nd stage's management.

Labor induction in China: a nationwide survey

BACKGROUND

Overmedicalization in labor management and delivery, including labor induction, is an increasing global concern. But detailed epidemiological data on labor induction in China remains unclear.

METHODS

This was a cross-sectional study of data (2015-2016) from 96 hospitals in 24 (of 34) Chinese administrative divisions. Multivariable logistic regression analysis was used to assess the association between medical conditions and cesarean delivery among women undergoing induction. Linear regression analysis was performed to assess the association between the prelabor cesarean delivery and labor-induction rates in each hospital. The impacts of labor induction and prelabor cesarean delivery on maternal and neonatal outcomes were compared in low-risk women.

RESULTS

Among 73 901 eligible participants, 48.1% were nulliparous. The overall weighted rate of labor induction in China was 14.2% (95% CI, 11.1-17.2%), with 18.4% (95% CI, 14.5-22.3%) in nulliparas and 10.2% (95% CI, 7.7-12.8%) in multiparas. Regardless of the induction method, the overall vaginal delivery rate was 72.9% (95% CI, 68.6-77.3%) in nulliparas and 86.6% (95% CI, 79.7-93.5%) in multiparas. Hospitals with a higher rate of nonmedically indicated cesarean delivery had a lower labor-induction rate in nulliparas (β =  - 0.57%; 95% CI, - 0.92 to - 0.22%; P = 0.002). Compared with prelabor cesarean delivery, labor induction in low-risk women was not associated with adverse maternal and neonatal outcomes.

CONCLUSION

The 2015-2016 labor-induction rate in China was 18.4% in nulliparas and 10.2% in multiparas. The proportion of prelabor cesarean delivery may contribute to regional differences in the labor-induction rate. Compared with prelabor cesarean delivery, labor induction in low-risk women may not increase severe maternal and neonatal morbidity.

Women's views and preferences regarding the mode of birth after cesarean section: Polish cross-sectional web-based survey

OBJECTIVE

Currently, the most common indication for cesarean section is a previous cesarean section. Some of them are performed for no medical reasons. Therefore, it is crucial to recognize the preferences and expectations of women concerning birth after cesarean section. This study's main aim was to understand the women's points of view on the mode of birth after cesarean.

STUDY DESIGN

A cross-sectional study was conducted, and data was collected using an original structured online questionnaire. The study group consisted of 733 pregnant Polish women who had previously undergone a cesarean birth.

RESULTS

Women more often preferred vaginal birth after cesarean section (73.26%) and less frequently (23.33%) chose elective cesarean section. Women preferring VBAC when making decisions were guided by the benefits, opportunities, and risks associated with each mode of birth. For women preferring elective cesarean section the only highly significant factor was the experience of previous deliveries. Women mainly use Internet sources and the support of other women giving birth after cesarean section. More than half of the women did not talk about the mode of birth with their midwife, and every fifth did not talk about it with the obstetrician.

CONCLUSION

Obstetric history and personal beliefs about birth after cesarean section, motivations, and concerns about childbirth affect women's preferences regarding the mode of birth. It is necessary to educate women, in particular, talks about the opportunities and risks associated with cesarean birth carried out by the medical staff at an early stage of pregnancy.

Prediction of Emergency Cesarean Section Using Machine Learning Methods: Development and External Validation of a Nationwide Multicenter Dataset in Republic of Korea

This study was a multicenter retrospective cohort study of term nulliparous women who underwent labor, and was conducted to develop an automated machine learning model for prediction of emergent cesarean section (CS) before onset of labor. Nine machine learning methods of logistic regression, random forest, Support Vector Machine (SVM), gradient boosting, extreme gradient boosting (XGBoost), light gradient boosting machine (LGBM), k-nearest neighbors (KNN), Voting, and Stacking were applied and compared for prediction of emergent CS during active labor. External validation was performed using a nationwide multicenter dataset for Korean fetal growth. A total of 6549 term nulliparous women was included in the analysis, and the emergent CS rate was 16.1%. The C-statistics values for KNN, Voting, XGBoost, Stacking, gradient boosting, random forest, LGBM, logistic regression, and SVM were 0.6, 0.69, 0.64, 0.59, 0.66, 0.68, 0.68, 0.7, and 0.69, respectively. The logistic regression model showed the best predictive performance with an accuracy of 0.78. The machine learning model identified nine significant variables of maternal age, height, weight at pre-pregnancy, pregnancy-associated hypertension, gestational age, and fetal sonographic findings. The C-statistic value for the logistic regression machine learning model in the external validation set (1391 term nulliparous women) was 0.69, with an overall accuracy of 0.68, a specificity of 0.83, and a sensitivity of 0.41. Machine learning algorithms with clinical and sonographic parameters at near term could be useful tools to predict individual risk of emergent CS during active labor in nulliparous women.

Aspects of Pelvic Floor Protection in Spontaneous Delivery - a Review

The necessity of increasingly addressing aspects of pelvic floor protection, i.e., prevention of the most frequent female pelvic floor disorders, such as urinary incontinence, faecal incontinence and pelvic organ prolapse, is the result of the steadily improving understanding of the association of pregnancy and delivery with the prevalence of these disorders. About a quarter of all women experience one or more such symptoms during their life. Apart from age and weight, pregnancies and births play an important part. While initial discussion of pelvic floor protection often focused very rapidly on the mode of delivery and elective caesarean section as a possible protective intervention, it has become apparent in the last few decades how varied and wide-ranging the options are that can be used to protect against pelvic floor disorders. The mode of delivery as such is "only" one element among numerous other considerations and has diminished markedly in importance. Interprofessionality and interdisciplinarity undoubtedly represent an important development as resulting recommendations must always be incorporated in an overall context that considers mother and child at the same time. Considering the pelvic floor only certainly does not make sense. This review article will analyze in greater detail important pre-, intra- and postpartum aspects that in their entirety can provide insight into the various aspects of pelvic floor protection. The authors regard the following article as an additional basis for discussion on achieving a sustained reduction in the incidence and prevalence of female pelvic floor disorders.

Childbirth fear, birth-related mindset and knowledge in non-pregnant women without birth experience

Background

Childbirth fear and interventions during childbirth might be related to the mindset and knowledge non-pregnant women have regarding childbirth. Non-pregnant women before their first birth experience may be particularly at risk for childbirth fear.

Methods

The present study examined the expressions and associations of birth-related mindset, knowledge, and fear among 316 young, non-pregnant women without birth experience. They participated in a cross-sectional online study and completed the Childbirth Fear Prior to Pregnancy, the Mindset and Birth Questionnaire, and a birth knowledge test.

Results

Most women (44%) had a natural mindset and low fear, 29% had a medical mindset and low fear, 8% natural mindset and higher fear, and 19% medical mindset and higher fear.

There were no differences in knowledge between the four groups. Some gaps in knowledge appeared concerning signs of beginning birth, and non-medical approaches to pain relief. From women with natural mindset and low childbirth fear, a higher percentage (13%) has already watched a birth, as compared to the other groups.

Natural mindset was associated with lower childbirth fear, whereas knowledge was independent from childbirth fear. Higher knowledge was low associated with natural mindset. Mindset and childbirth fear were independent from age and education degree.

Conclusions

Gynecologists, midwifes and other health professionals may develop an awareness for birth as a natural event in their non-pregnant patients, and take birth-related fear into account in their counseling, with focus on women’s self-efficacy and non-medical approaches to pain relief.

Intention to Exclusively Breastfeed Is Associated with Lower Rates of Cesarean Section for Nonmedical Reasons in a Cohort of Mothers in Vietnam

Background: Breastfeeding brings benefits to both mothers and children in the short term and long term. Unnecessary cesarean sections can bring risks to both parties. This study was undertaken to examine the relationship between exclusive breastfeeding intention and cesarean delivery. Methods: We analyzed data collected from 554 single mothers who delivered in Dong Anh General District Hospital or Hanoi Obstetrics and Gynecology Hospital, Vietnam, in 2020–2021. The relationship between exclusive breastfeeding intention and cesarean delivery for nonmedical reasons was adjusted for maternal education, maternal age, parity, history of fetal loss, having at least eight antenatal contacts, hospital of delivery, child sex, and birth weight. Results: Antenatally, 34.8% (184/529) of mothers intended to breastfeed exclusively until 6 months and 30.8% (84/274) underwent cesarean section for a nonmedical reason. After adjusting for other factors, mothers who intended to breastfeed exclusively until 6 months were less likely to undergo cesarean delivery for nonmedical reasons (OR = 0.55, 95% CI: 0.31–0.96, p = 0.034). Conclusions: This study adds to the growing evidence related to unnecessary cesarean sections and routine over-medicalization of normal birth in the urban areas of Vietnam. The association between breastfeeding intentions and a lower rate of cesarean section suggests that education on breastfeeding could be a useful intervention for reducing the rate of cesarean sections and improving maternal and child health.

Impact of maternal nationality on caesarean section rate variation in a high-income country

BACKGROUND

Caesarean section (CS) rates have been reported to differ between immigrants and native-born women in high-income countries.

OBJECTIVE

We assessed the CS rate and its relationship with the CS rate in country of nationality and other explanatory factors among women of different nationalities including Qatari women who underwent deliveries at our hospital to generate evidence that will quantify and help explain the observed CS rates in our hospital.

METHODS

In this retrospective cross-sectional study conducted at the second-largest public maternity hospital in Qatar, Al-Wakra Hospital (AWH), data for all births delivered in 2019 were retrieved from the hospital's electronic medical records. The CS rates and the crude and adjusted risks of Caesarean delivery for mothers from each nationality were determined, and the common indications for CS were analyzed based on nationality. The association between nationality and Caesarean delivery was examined using binomial logistic regression analysis, with Qatari women as the reference group. The correlation between CS rate in country of nationality and observed CS rates in Qatar was also examined using Pearson's correlation.

RESULTS

The study population consisted of 4816 births by women of 68 nationalities, of which 4513 births were by women from 25 countries. The highest proportion of deliveries (n-1247, 25.9%) was by Indian women. The frequency of CS was the highest and lowest among Egyptian (49.6%) and Yemeni women (17.9%), respectively. Elective CS was predominantly performed in women of Arab nationalities; the most common indication was a history of previous multiple CSs. Emergency CS was primarily performed in women of Asian and Sub-Saharan African nationalities; the most common indications were failure to progress and fetal distress. For most nationalities, the CS rate in Qatar was associated with those of the countries of nationality.

CONCLUSIONS

The observed CS rates varied widely among women of different nationalities. The variation was influenced by maternal factors and medical indications as well as the CS rates in the country of nationality. We posit that cultural preferences, acculturation, and patient expectations influenced observed findings. More efforts are required to reduce primary CS rates and to help women make the most informed decisions regarding modes of delivery. Key Message: CS rates varied widely among women of different nationalities. The variation was influenced by medical indications, maternal preferences, and CS rate in countries of nationality. The solution to reducing CS rates should be a culturally informed response.

Composite non-clinical interventions for a safe cesarean section rate reduction: results of a pre-post interventional study

OBJECTIVE

To evaluate the impact on cesarean section (CS) rate with of a program of multiple non-clinical interventions targeted at health-care professional within a hospital maternity ward.

MATERIALS AND METHODS

Retrospective quasi-experimental pre-post intervention study with an historical control group conducted in a second-level teaching hospital. All women who gave birth in the period 2014 to 2018 were included. A series of multiple non-clinical interventions including a dedicated team of obstetricians for delivery room and antenatal counseling, monthly internal audits and physician education by local opinion leader were prospectively introduced from September 2016. The primary outcome of the study was the CS rate. The incidences of operative vaginal delivery, 3rd-/4th-degree perineal tears and further maternal and neonatal complications were considered as secondary outcomes.

RESULTS

The CS rate dropped from 33.05 to 26.06% after starting the interventions (p < 0.01); in particular, the cumulative rate of CS performed during labor decreased significantly from 19.46 to 14.11% (p < 0.01). CS reduction was still statistically significant after multivariate correction (OR = 0.66, CI.95 = 0.57-0.76, p < 0.01). Results further showed an increased prevalence of 3rd-degree perineal tears (0.97% versus 2.24%, p < 0.01), present also after correcting for possible confounding factors (OR = 2.36, CI.95 = 1.48-3.76, p < 0.01). No differences were found in the rate of vaginal-operative births and further maternal complications, while the composite neonatal outcome was found to be improved (OR = 0.73, CI.95 = 0.57-0.93, p = 0.010).

CONCLUSIONS

The introduction of multiple non-clinical interventions can significantly reduce the CS rate. However, beside an improvement in neonatal composite outcome, a potential increase in high-degree perineal tears should be taken in account.

A Retrospective Study of the Association of Repeated Attempts at Trial of Labor After Cesarean Birth on Maternal and Neonatal Outcomes

Purpose

To assess the maternal and neonatal outcomes of repeated trials of labor after one previous cesarean section.

Materials and Methods

We identified and reviewed the records of all women who had had a trial of labor after cesarean section at a tertiary care center in Saudi Arabia between January 1, 2011, and December 30, 2018. The inclusion criteria were women with singleton vertex pregnancies between 24 and 42 weeks of gestation and a trial of labor after one cesarean section. The exclusion criteria were two or more previous cesarean sections, intrauterine fetal demise, breech presentation, labor induction, estimated fetal weight >4 kg, and classical or low vertical uterine incision. The pregnancy outcomes of these women were compared according to the number of trials of labor after cesarean section.

Results

During the study period, 1139 women met the inclusion criteria. The number of women with previous zero, one, two, or three or more trials of labor after cesarean section were 669 (58.7%), 237 (20.8%), 132 (11.6%), and 101 (8.9%), respectively. There were statistically significant trends between the four groups in age, nationality, gravidity, and parity but not in the booking status, BMI, or the hemoglobin level before a trial of labor after cesarean section. The rate of vaginal birth after cesarean section increased significantly (p<0.001) from 72.9% with zero to 93.3% with one, 93.9% with two, and 94.1% with three or more trials of labor after cesarean section.

Conclusion

Previously successful vaginal births after cesarean delivery are associated with improved maternal and neonatal outcomes in the subsequent trials of labor after cesarean delivery.

Reduction in Cesarean Delivery Rates Associated With a State Quality Collaborative in Maryland

OBJECTIVE

To assess the extent to which hospitals participating in the MDPQC (Maryland Perinatal-Neonatal Quality Care Collaborative) to reduce primary cesarean deliveries adopted policy and practice changes and the association of this adoption with state-level cesarean delivery rates.

METHODS

This prospective evaluation of the MDPQC includes 31 (97%) of the birthing hospitals in the state, which all voluntarily participated in the 30-month collaborative from June 2016 to December 2018. Hospital teams agreed to implement practices from the "Safe Reduction of Primary Cesarean Births" patient safety bundle, developed by the Council on Patient Safety in Women's Health Care. Each hospital's implementation of practices in the bundle was measured through surveys of team leaders at 12 months and 30 months. Half-yearly cesarean delivery rates were calculated from aggregate birth certificate data for each hospital, and differences in rates between the 6 months before the collaborative (baseline) and the 6 months afterward (endline) were tested for statistical significance.

RESULTS

Among the 26 bundle practices that were assessed, participating hospitals reported having a median of seven practices (range 0-23) already in place before the collaborative and implementing a median of four (range 0-17) new practices during the collaborative. Across the collaborative, the cesarean delivery rates decreased from 28.5% to 26.9% (P=.011) for all nulliparous term singleton vertex births and from 36.1% to 31.3% (P<.001) for nulliparous, term, singleton, vertex inductions. Five hospitals had a statistically significant decrease in nulliparous, term, singleton, vertex cesarean delivery rates and four had a significant increase. Nulliparous, term, singleton, vertex cesarean delivery rates were significantly lower across hospitals that implemented more practices in the "Response" domain of the bundle.

CONCLUSION

The MDPQC was associated with a statewide reduction in cesarean delivery rates for nulliparous, term, singleton, vertex births.

Trends and projections of caesarean section rates: global and regional estimates

Background

The caesarean section (CS) rate continues to increase across high-income, middle-income and low-income countries. We present current global and regional CS rates, trends since 1990 and projections for 2030.

Methods

We obtained nationally representative data on the CS rate from countries worldwide from 1990 to 2018. We used routine health information systems reports and population-based household surveys. Using the latest available data, we calculated current regional and subregional weighted averages. We estimated trends by a piecewise analysis of CS rates at the national, regional and global levels from 1990 to 2018. We projected the CS rate and the number of CS expected in 2030 using autoregressive integrated moving-average models.

Results

Latest available data (2010–2018) from 154 countries covering 94.5% of world live births shows that 21.1% of women gave birth by caesarean worldwide, averages ranging from 5% in sub-Saharan Africa to 42.8% in Latin America and the Caribbean. CS has risen in all regions since 1990. Subregions with the greatest increases were Eastern Asia, Western Asia and Northern Africa (44.9, 34.7 and 31.5 percentage point increase, respectively) while sub-Saharan Africa and Northern America (3.6 and 9.5 percentage point increase, respectively) had the lowest rise. Projections showed that by 2030, 28.5% of women worldwide will give birth by CS (38 million caesareans of which 33.5 million in LMIC annually) ranging from 7.1% in sub-Saharan Africa to 63.4% in Eastern Asia.

Conclusion

The use of CS has steadily increased worldwide and will continue increasing over the current decade where both unmet need and overuse are expected to coexist. In the absence of global effective interventions to revert the trend, Southern Asia and sub-Saharan Africa will face a complex scenario with morbidity and mortality associated with the unmet need, the unsafe provision of CS and with the concomitant overuse of the surgical procedure which drains resources and adds avoidable morbidity and mortality. If the Sustainable Development Goals are to be achieved, comprehensively addressing the CS issue is a global priority.

Trends and sociodemographic inequalities in the use of caesarean section in Indonesia, 1987-2017

INTRODUCTION

Caesarean section (CS) rates are increasing globally. CS can be a live-saving procedure when medically indicated, but it comes with higher risks for women and newborns when done without medical indication. Crucially, inequalities in who receives CS exist, both within and across countries. Understanding factors driving increasing rates and inequalities of CS is imperative to optimise the use of this life-saving intervention. This study aimed to investigate trends of CS use and inequalities across sociodemographic characteristics in Indonesia over a 30-year period.

METHODS

Seven waves of the Indonesia Demographic and Health Survey were used to estimate trends and inequalities in CS from 1987 to 2017. Relative and absolute inequalities across a range of sociodemographic characteristics were estimated and trends in inequalities were assessed through changes in rate ratio and rate difference.

RESULTS

The proportion of facility-based births in Indonesia has increased in the past 30 years, coinciding with an increase in CS rate (CSR) (1991 CSR: 1.6% (95% CI 1.3 to 1.9); 2017 CSR: 17.6% (95% CI 16.7 to 18.5)). Higher rates of CS are observed mostly in Western Indonesia, while lower CSRs are observed in Eastern Indonesia. Inequalities of CSRs in Indonesia are observed across type of health facility (public/private), regions, places of residence, wealth quintiles and maternal education, with the highest CSRs in more affluent and educated groups. Widening absolute inequalities of CS are observed across all sociodemographic characteristics, except facility type, where CSR gaps between public and private facilities have closed on both relative and absolute scales.

CONCLUSION

This study provides evidence of increasing trends in CSRs and widening absolute inequalities in CSRs across different sociodemographic groups of women in Indonesia. The context of increasing CSRs across society, however, may have resulted in more stable relative inequalities. Improving understanding of the drivers of these trends in Indonesia and, particularly, of women's and providers' perspectives and preferences for childbirth, should be prioritised to optimise the use of CS.

The Myometrium in Pregnant Women with Obesity

Obesity is a worldwide public health problem, affecting at least one-third of pregnant women. One of the main problems of obesity during pregnancy is the resulting high rate of cesarean section. The leading cause of this higher frequency of cesarean sections in obese women, compared with that in nonobese women, is an altered myometrial function that leads to lower frequency and potency of contractions. In this article, the disruptions of myometrial myocytes were reviewed in obese women during pregnancy that may explain the dysfunctional labor. The myometrium of obese women exhibited lower expression of connexin43, a lower function of the oxytocin receptor, and higher activity of the potassium channels. Adipokines, such as leptin, visfatin, and apelin, whose concentrations are higher in obese women, decreased myometrial contractility, perhaps by inhibiting the myometrial RhoA/ROCK pathway. The characteristically higher cholesterol levels of obese women alter myometrial myocyte cell membranes, especially the caveolae, inhibiting oxytocin receptor function, and increasing the K+ channel activity. All these changes in the myometrial cells or their environment decrease myometrial contractility, at least partially explaining the higher rate of cesarean of sections in obese women.
