RESUMO

INTRODUCTION: Public and patient involvement can provide crucial insights to optimise research by enhancing relevance and appropriateness of studies. The World Health Organization (WHO) engaged in an inclusive process to ensure that both technical experts and women had a voice in defining the research gaps and needs to increase or reintroduce the use of assisted vaginal birth (AVB) in settings where this intervention is needed but unavailable or underused. METHODS: We describe the methods and outcomes of online workshops led by WHO to obtain women representatives' perspectives about AVB research gaps and needs. RESULTS: After technical experts created a list of research questions based on various evidence syntheses, WHO organised four online workshops with 31 women's representatives from 27 mostly low- and middle-income (LMIC) countries. Women rated the importance and priority of the research questions proposed by the technical experts, improving and broadening some of them, added new questions, and voiced their main concerns and views about AVB. Women helped to put the research questions into context in their communities, highlighted neglected factors/dimensions that influence practices and affect women's experience during labour and childbirth, underscored less salient consequences of AVB, and highlighted the main concerns of women about research on AVB. The consolidated vision of technical experts and women's representatives resulted in a technical brief published by WHO. The technical brief is expected to stimulate global research and action closely aligned with women's priorities. CONCLUSIONS: We describe a successful experience of engaging women, mostly from LMICs, in the identification of research gaps and needs to reintroduce AVB use. This process contributed to better aligning research questions with women's views, concerns, and priorities. Given the scarcity of reports about engaging women from LMICs to optimise research, this successful experience can serve as an inspiration for future work. PATIENT OR PUBLIC CONTRIBUTION: Women representatives were involved at every stage of the workshops described in full in this manuscript.

RESUMO

INTRODUCTION: Caesarean section (CS) rates in Indonesia are increasing rapidly. Understanding women's preferences about mode of birth is important to help contextualise these rising rates and can help develop interventions to optimise CS. This study aimed to explore Indonesian women's preferences and decision-making about mode of birth, and how their preferences may change throughout pregnancy and birth. METHODS: We conducted a longitudinal qualitative study using in-depth interviews with 28 women accessing private and public health facilities in Jakarta, the region with the highest CS rates. Interviews were conducted two times: during the woman's third trimester of pregnancy and in the postpartum period, between October 2022 and March 2023. We used a reflexive thematic approach for analysis. RESULTS: We generated three themes: (1) preferences about the mode of birth, (2) decision-making about the mode of birth and (3) regrets about the actual mode of birth. Most women preferred vaginal birth. However, they were influenced by advertisements promoting enhanced recovery after CS (ERACS) as an 'advanced technique' of CS, promising a comfortable, painless and faster recovery birth. This messaging influenced women to perceive CS as equivalent or even superior to vaginal birth. Where women's preferences for mode of birth shifted around the time of birth, this was primarily due to the obstetricians' discretion. Women felt they did not receive adequate information from obstetricians on the benefits and risks of CS and vaginal birth and felt disappointed when their actual mode of birth was not aligned with their preferences. CONCLUSION: Our study shows that despite rising CS rates, Indonesian women prefer vaginal birth. This highlights the need for better communication strategies and evidence-based information from healthcare providers. Given the rising popularity of ERACS, more work is urgently needed to standardise and regulate its use.

RESUMO

Background: Caesarean section (CS) is the most performed major surgery worldwide. Surgical techniques used for CS vary widely and there is no internationally accepted standardization. We conducted an overview of systematic reviews (SR) of randomized controlled trials (RCT) to summarize the evidence on surgical techniques or procedures related to CS. Methods: Searches were conducted from database inception to 31 January 2024 in Cochrane Database of Systematic Reviews, PubMed, EMBASE, Lilacs and CINAHL without date or language restrictions. AMSTAR 2 and GRADE were used to assess the methodological quality of the SRs and the certainty of evidence at outcome level, respectively. We classified each procedure-outcome pair into one of eight categories according to effect estimates and certainty of evidence. The overview was registered at PROSPERO (CRD 42023208306). Findings: The analysis included 38 SRs (16 Cochrane and 22 non-Cochrane) published between 2004-2024 involving 628 RCT with a total of 190,349 participants. Most reviews were of low or critically low quality (AMSTAR 2). The SRs presented 345 procedure-outcome comparisons (237 procedure versus procedure, 108 procedure versus no treatment/placebo). There was insufficient or inconclusive evidence for 256 comparisons, clear evidence of benefit for 40, possible benefit for 17, no difference of effect for 13, clear evidence of harm for 14, and possible harm for 5. We found no SRs for 7 pre-defined procedures. Skin cleansing with chlorhexidine, Joel-Cohen-based abdominal incision, uterine incision with blunt dissection and cephalad-caudal expansion, cord traction for placental extraction, manual cervical dilatation in pre-labour CS, changing gloves, chromic catgut suture for uterine closure, non-closure of the peritoneum, closure of subcutaneous tissue, and negative pressure wound therapy are procedures associated with benefits for relevant outcomes. Interpretation: Current evidence suggests that several CS surgical procedures improve outcomes but also reveals a lack of or inconclusive evidence for many commonly used procedures. There is an urgent need for evidence-based guidelines standardizing techniques for CS, and trials to fill existing knowledge gaps. Funding: UNDP-UNFPA-UNICEF-WHO-World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP), a cosponsored programme executed by the World Health Organization (WHO).

RESUMO

OBJECTIVE: To measure the proportion of women's preferences for CS in hospitals with high caesarean section rates and to identify related factors. DESIGN: A cross-sectional hospital-based postpartum survey was conducted. We used multilevel multivariate logistic regression and probit models to analyse the association between women's caesarean section preferences and maternal characteristics. Probit models take into account selection bias while excluding women who had no preference. SETTING: Thirty-two hospitals in Argentina, Thailand, Vietnam and Burkina Faso were selected. PARTICIPANTS: A total of 1,979 post-partum women with no potential medical need for caesarean section were included among a representative sample of women who delivered at each of the participating facilities during the data collection period. FINDINGS: The overall caesarean section rate was 23.3 %. Among women who declared a preference in late pregnancy, 9 % preferred caesarean section, ranging from 1.8 % in Burkina Faso to 17.8 % in Thailand. Primiparous women were more likely to prefer a caesarean section than multiparous women (ß=+0.16 [+0.01; +0.31]; p = 0.04). Among women who preferred caesarean section, doctors were frequently cited as the main influencers, and "avoid pain in labour" was the most common perceived benefit of caesarean section. KEY CONCLUSIONS: Our results suggest that a high proportion of women prefer vaginal birth and highlight that the preference for caesarean section is linked to women's fear of pain and the influence of doctors. These results can inform the development of interventions aimed at supporting women and their preferences, providing them with evidence-based information and changing doctors' behaviour in order to reduce the number of unnecessary caesarean sections. CLINICAL TRIAL REGISTRY: The QUALI-DEC trial is registered on the Current Controlled Trials website (https://www.isrctn.com/) under the number ISRCTN67214403.

RESUMO

Maternal outcomes throughout pregnancy, childbirth, and the postnatal period are influenced by interlinked and interdependent vulnerabilities. A comprehensive understanding of how various threats and barriers affect maternal and perinatal health is critical to plan, evaluate and improve maternal health programmes. This paper builds on the introductory paper of the Series on the determinants of maternal health by assessing vulnerabilities during pregnancy, childbirth, and the postnatal period. We synthesise and present the concept of vulnerability in pregnancy and childbirth, and map vulnerability attributes and their dynamic influence on maternal outcomes in early and late pregnancy and during childbirth and the postnatal period, with a particular focus on low-income and middle-income countries (LMICs). We summarise existing literature and present the evidence on the effects of various reparative strategies to improve pregnancy and childbirth outcomes. Lastly, we discuss the implications of the identified vulnerability attributes and reparative strategies for the efforts of policymakers, healthcare professionals, and researchers working towards improving outcomes for women and birthing people in LMICs.

RESUMO

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-Nasaud, 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.

RESUMO

BACKGROUND: Improving the understanding of non-clinical factors that lead to the increasing caesarean section (CS) rates in many low- and middle-income countries is currently necessary to meet the challenge of implementing effective interventions in hospitals to reverse the trend. The objective of this study was to study the influence of organizational factors on the CS use in Argentina, Vietnam, Thailand and Burkina Faso. METHODS: A cross-sectional hospital-based postpartum survey was conducted in 32 hospitals (8 per country). We selected women with no potential medical need for CS among a random sample of women who delivered at each of the participating facilities during the data collection period. We used multilevel multivariable logistic regression to analyse the association between CS use and organizational factors, adjusted on women's characteristics. RESULTS: A total of 2,092 low-risk women who had given birth in the participating hospitals were included. The overall CS rate was 24.1%, including 4.9% of pre-labour CS and 19.3% of intra-partum CS. Pre-labour CS was significantly associated with a 24-hour anaesthetist dedicated to the delivery ward (ORa = 3.70 [1.41; 9.72]) and with the possibility to have an individual room during labour and delivery (ORa = 0.28 [0.09; 0.87]). Intra-partum CS was significantly associated with a higher bed occupancy level (ORa = 1.45 [1.09; 1.93]): intrapartum CS rate would increase of 6.3% points if the average number of births per delivery bed per day increased by 10%. CONCLUSION: Our results suggest that organisational norms and convenience associated with inadequate use of favourable resources, as well as the lack of privacy favouring women's preference for CS, and the excessive workload of healthcare providers drive the CS overuse in these hospitals. It is also crucial to enhance human and physical resources in delivery rooms and the organisation of intrapartum care to improve the birth experience and the working environment for those providing care. TRIAL REGISTRATION: The QUALI-DEC trial is registered on the Current Controlled Trials website ( https://www.isrctn.com/ ) under the number ISRCTN67214403.

RESUMO

BACKGROUND: Previous studies reported conflicting results on the relationship between oxytocin use for labor augmentation and the risk of postpartum hemorrhage, probably because it is rather challenging to disentangle oxytocin use from labor dystocia. OBJECTIVE: This study aimed to investigate the independent association between oxytocin use for augmentation and the risk of postpartum hemorrhage by using advanced statistical modeling to control for labor patterns and other covariates. STUDY DESIGN: We used data from 20,899 term, cephalic, singleton pregnancies of patients with spontaneous onset of labor and no previous cesarean delivery from Intermountain Healthcare in Utah in the Consortium on Safe Labor. Presence of postpartum hemorrhage was identified on the basis of a clinical diagnosis. Propensity scores were calculated using a generalized linear mixed model for oxytocin use for augmentation, and covariate balancing generalized propensity score was applied to obtain propensity scores for the duration and total dosage of oxytocin augmentation. A weighted generalized additive mixed model was used to depict dose-response curves between the duration and total dosage of oxytocin augmentation and the outcomes. The average treatment effects of oxytocin use for augmentation on postpartum hemorrhage and estimated blood loss (mL) were assessed by inverse probability weighting of propensity scores. RESULTS: The odds of both postpartum hemorrhage and estimated blood loss increased modestly when the duration and/or total dosage of oxytocin used for augmentation increased. However, in comparison with women for whom oxytocin was not used, oxytocin augmentation was not clinically or statistically significantly associated with estimated blood loss (6.5 mL; 95% confidence interval, 2.5-10.3) or postpartum hemorrhage (adjusted odds ratio, 1.02; 95% confidence interval, 0.82-1.24) when rigorously controlling for labor pattern and potential confounders. The results remained consistent regardless of inclusion of women with an intrapartum cesarean delivery. CONCLUSION: The odds of postpartum hemorrhage and estimated blood loss increased modestly with increasing duration and total dosage of oxytocin augmentation. However, in comparison with women for whom oxytocin was not used and after controlling for potential confounders, there was no clinically significant association between oxytocin use for augmentation and estimated blood loss or the risk of postpartum hemorrhage.

RESUMO

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.

RESUMO

OBJECTIVES: Daily calcium supplements are recommended for pregnant women from 20 weeks' gestation to prevent pre-eclampsia in populations with low dietary calcium intake. We aimed to improve understanding of barriers and facilitators for calcium supplement intake during pregnancy to prevent pre-eclampsia. DESIGN: Mixed-method systematic review, with confidence assessed using the Grading of Recommendations, Assessment, Development and Evaluations-Confidence in the Evidence from Reviews of Qualitative research approach. DATA SOURCES: MEDLINE and EMBASE (via Ovid), CINAHL and Global Health (via EBSCO) and grey literature databases were searched up to 17 September 2022. ELIGIBILITY CRITERIA: We included primary qualitative, quantitative and mixed-methods studies reporting implementation or use of calcium supplements during pregnancy, excluding calcium fortification and non-primary studies. No restrictions were imposed on settings, language or publication date. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted data and assessed risk of bias. We analysed the qualitative data using thematic synthesis, and quantitative findings were thematically mapped to qualitative findings. We then mapped the results to behavioural change frameworks to identify barriers and facilitators. RESULTS: Eighteen reports from nine studies were included in this review. Women reported barriers to consuming calcium supplements included limited knowledge about calcium supplements and pre-eclampsia, fears and experiences of side effects, varying preferences for tablets, dosing, working schedules, being away from home and taking other supplements. Receiving information regarding pre-eclampsia and safety of calcium supplement use from reliable sources, alternative dosing options, supplement reminders, early antenatal care, free supplements and support from families and communities were reported as facilitators. Healthcare providers felt that consistent messaging about benefits and risks of calcium, training, and ensuring adequate staffing and calcium supply is available would be able to help them in promoting calcium. CONCLUSION: Relevant stakeholders should consider the identified barriers and facilitators when formulating interventions and policies on calcium supplement use. These review findings can inform implementation to ensure effective and equitable provision and scale-up of calcium interventions. PROSPERO REGISTRATION NUMBER: CRD42021239143.

RESUMO

Access to emergency obstetric care, including assisted vaginal birth and caesarean birth, is crucial for improving maternal and childbirth outcomes. However, although the proportion of births by caesarean section has increased during the last few decades, the use of assisted vaginal birth has declined. This is particularly the case in low- and middle-income countries, despite an assisted vaginal birth often being less risky than caesarean birth. We therefore conducted a three-step process to identify a research agenda necessary to increase the use of, or reintroduce, assisted vaginal birth: after conducting an evidence synthesis, which informed a consultation with technical experts who proposed an initial research agenda, we sought and incorporated the views of women's representatives of this agenda. This process has allowed us to identify a comprehensive research agenda, with topics categorized as: (i) the need to understand women's perceptions of assisted vaginal birth, and provide appropriate and reliable information; (ii) the importance of training health-care providers in clinical skills but also in respectful care, effective communication, shared decision-making and informed consent; and (iii) the barriers to and facilitators of implementation and sustainability. From women's feedback, we learned of the urgent need to recognize labour, childbirth and postpartum experiences as inherently physiological and dignified human processes, in which interventions should only be implemented if necessary. The promotion and/or reintroduction of assisted vaginal birth in low-resource settings requires governments, policy-makers and hospital administrators to support skilled health-care providers who can, in turn, respectfully support women in labour and childbirth.


L'accès aux soins obstétriques d'urgence, y compris l'accouchement vaginal assisté et la césarienne, est essentiel pour améliorer les effets de la maternité et de l'accouchement. Toutefois, bien que la proportion de césariennes ait augmenté ces dernières décennies, le recours à l'accouchement vaginal assisté a diminué. C'est particulièrement le cas dans les pays à revenu faible ou intermédiaire, bien que l'accouchement vaginal assisté soit souvent moins risqué qu'une césarienne. Nous avons donc mené un processus en trois étapes afin d'imaginer un programme de recherche qui permettrait d'augmenter le recours à l'accouchement vaginal assisté ou de le réintroduire. Après avoir réalisé une synthèse des données probantes, qui a servi de base à une consultation avec des experts techniques qui ont proposé un programme de recherche initial, nous avons sollicité et incorporé les avis des représentantes des femmes pour ce programme. Ce processus nous a permis d'imaginer un programme de recherche complet, avec des sujets classés comme suit: (i) la nécessité de comprendre la perception qu'ont les femmes de l'accouchement vaginal assisté et de fournir des informations appropriées et fiables; (ii) l'importance de la formation des prestataires de soins de santé en matière de compétences cliniques, mais aussi de respect dans les soins de santé, de communication efficace, de prise de décision partagée et de consentement éclairé; ou (iii) les obstacles à la mise en œuvre et à la durabilité et les facteurs qui les facilitent. Les réactions de femmes nous ont appris qu'il était urgent de reconnaître que l'accouchement, la naissance et le post-partum sont des processus humains intrinsèquement physiologiques et dignes au cours desquels les interventions ne devraient être mises en œuvre qu'en cas de nécessité. La promotion et/ou la réintroduction de l'accouchement vaginal assisté dans les régions à faibles ressources nécessitent que les pouvoirs publics, les décideurs politiques et les administrations d'hôpitaux soutiennent les prestataires de soins de santé qualifiés, qui pourront à leur tour soutenir respectueusement les femmes pendant l'accouchement.


El acceso a la atención obstétrica de emergencia, incluido el parto vaginal asistido y el parto por cesárea, es crucial para mejorar los resultados de la maternidad y el parto. No obstante, aunque el porcentaje de partos por cesárea ha aumentado en las últimas décadas, el uso del parto vaginal asistido ha disminuido. Esto ocurre especialmente en los países de ingresos bajos y medios, a pesar de que un parto vaginal asistido suele ser menos arriesgado que un parto por cesárea. Por lo tanto, llevamos a cabo un proceso de tres pasos para identificar un programa de investigación necesario para aumentar el uso del parto vaginal asistido o volver a incorporarlo: tras realizar una síntesis de la evidencia, que sirvió de base para una consulta con expertos técnicos que propusieron un programa de investigación inicial, buscamos e integramos las opiniones de las representantes de las mujeres sobre este programa. Este proceso nos ha permitido identificar un programa de investigación exhaustivo, con temas categorizados como: (i) la necesidad de comprender las percepciones de las mujeres sobre el parto vaginal asistido, y proporcionar información adecuada y fiable; (ii) la importancia de formar a los profesionales sanitarios en habilidades clínicas, pero también en atención respetuosa, comunicación efectiva, toma de decisiones compartida y consentimiento informado; o (iii) las barreras y los facilitadores de la implementación y la sostenibilidad. A partir de las opiniones de las mujeres, nos enteramos de la urgente necesidad de reconocer las experiencias del parto, el alumbramiento y el posparto como procesos humanos inherentemente fisiológicos y dignos, en los que las intervenciones solo deben aplicarse si son necesarias. La promoción o la reincoporación del parto vaginal asistido en regiones de escasos recursos exige que los gobiernos, los responsables de formular políticas y los administradores de hospitales apoyen a los profesionales sanitarios capacitados que, a su vez, pueden ayudar a las mujeres en el trabajo de parto y el alumbramiento de manera respetuosa.

RESUMO

OBJECTIVES: To synthesise evidence on the perceptions of healthcare providers (HCPs) about the quality of oxytocin and misoprostol available in their settings, and their actions as a result of these perceptions. DESIGN: Mixed-methods systematic review. ELIGIBILITY CRITERIA: We included quantitative and qualitative studies reporting HCPs' perceptions about oxytocin or misoprostol quality. DATA SOURCES: We searched CINAHL, Cochrane Library, Ebscohost, Embase, PubMed, Global Index Medicus, Portal regional BVS, PsycNET, Scopus and Web of Science from inception to 31 March 2022 and grey literature. RISK OF BIAS: We used the Center for Evidence-Based Management critical appraisal tool for surveys. For qualitative studies, we used the Critical Appraisal Skills Programme tool. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers performed study selection, data extraction and quality assessment. We conducted separate quantitative and qualitative syntheses and integrated the evidence into a narrative synthesis (convergent segregated review design). RESULTS: We included five (three quantitative and two qualitative) studies, of moderate or high quality, conducted in low-income and middle-income countries (LMICs). In the three quantitative studies (N=7065 participants), 8.2-21.3% of HCPs had experienced problems due to known/suspected low-quality oxytocin and 3.3% due to low-quality misoprostol. In the two qualitative studies, perception of oxytocin quality varied. In quantitative studies, when confronted with suspected/known low-quality oxytocin, 29-78% of HCPs would inform a supervisor, 62% would document this in writing, 45-54% would change to another drug and 5-37% would double the dose of oxytocin. Qualitative evidence suggests that many HCPs do not formally report suspected low-quality oxytocin or misoprostol, and use higher doses or additional uterotonics. CONCLUSIONS: A proportion of HCPs from LMICs perceive oxytocin to be of low quality. There is very limited evidence on their perceptions about misoprostol. Many HCPs do not report suspected low-quality uterotonics but change to another medicine or double the dose of oxytocin. PROSPERO REGISTRATION NUMBER: CRD42022323812.

RESUMO

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.

RESUMO

OBJECTIVE: Both duration of labour and use of oxytocin for augmentation are known risk factors for postpartum haemorrhage but distinguishing between the significance of these factors is complex. In this study, we aimed to investigate the association between both labour duration and oxytocin augmentation, for postpartum haemorrhage. DESIGN: A cohort study based on a secondary analysis of a cluster-randomised trial. PARTICIPANTS AND SETTING: Term nulliparous women with a single foetus in cephalic presentation, spontaneous onset of active labour and a vaginal birth. The participants were originally included in cluster-randomised trial conducted in Norway from December 1, 2014, to January 31, 2017, that aimed to compare the frequency of intrapartum caesarean sections when adhering to the WHO partograph versus Zhang's guideline. MEASUREMENTS: The data were analysed through four statistical models. Model 1 investigated the effect of oxytocin augmentation as a dichotomous variable (yes/no); Model 2 investigated the effect of the duration of oxytocin augmentation; Model 3 investigated the effect of the maximum dose of oxytocin; and Model 4 investigated the effect of both the duration of augmentation and the maximum dose of oxytocin. All four models included duration of labour divided into five time-intervals. We used binary logistic regression to estimate the odds ratios of postpartum haemorrhage, defined as blood loss of ≥ 1000 ml, including a random intercept for hospital and mutually adjusting for oxytocin augmentation and labour duration in addition to maternal age, maternal marital status, maternal higher education level, maternal smoking habits in the first trimester, maternal body mass index and birth weight. FINDINGS: Model 1 found a significant association between the use of oxytocin and postpartum haemorrhage. In Model 2, oxytocin augmentation of ≥ 4.5 h was associated with postpartum haemorrhage. In Model 3, we found an association between a maximum dose of oxytocin of ≥ 20 mU/min and postpartum haemorrhage. Model 4 showed that a maximum dose of oxytocin ≥ 20 mU/min was associated with postpartum haemorrhage both for those augmented < 4.5 h and for those augmented ≥ 4.5 h. Duration of labour was associated with postpartum haemorrhage in all models if lasting ≥ 16 h. KEY CONCLUSIONS: We found both oxytocin augmentation and labour duration to be associated with postpartum haemorrhage. Oxytocin doses of ≥ 20 mU/min and a labour duration of ≥ 16 h showed an independent association. IMPLICATION FOR PRACTICE: The potent drug oxytocin should be carefully administered, as doses of ≥ 20 mU/min were associated with an increased risk of PPH, regardless of the duration of oxytocin augmentation.

RESUMO

INTRODUCTION: Low dietary calcium intake is a risk factor for pre-eclampsia, a major contributor to maternal and perinatal mortality and morbidity worldwide. Calcium supplementation can prevent pre-eclampsia in women with low dietary calcium. However, the optimal dose and timing of calcium supplementation are not known. We plan to undertake an individual participant data (IPD) meta-analysis of randomised trials to determine the effects of various calcium supplementation regimens in preventing pre-eclampsia and its complications and rank these by effectiveness. We also aim to evaluate the cost-effectiveness of calcium supplementation to prevent pre-eclampsia. METHODS AND ANALYSIS: We will identify randomised trials on calcium supplementation before and during pregnancy by searching major electronic databases including Embase, CINAHL, MEDLINE, CENTRAL, PubMed, Scopus, AMED, LILACS, POPLINE, AIM, IMSEAR, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform, without language restrictions, from inception to February 2022. Primary researchers of the identified trials will be invited to join the International Calcium in Pregnancy Collaborative Network and share their IPD. We will check each study's IPD for consistency with the original authors before standardising and harmonising the data. We will perform a series of one-stage and two-stage IPD random-effect meta-analyses to obtain the summary intervention effects on pre-eclampsia with 95% CIs and summary treatment-covariate interactions (maternal risk status, dietary intake, timing of intervention, daily dose of calcium prescribed and total intake of calcium). Heterogeneity will be summarised using tau2, I2 and 95% prediction intervals for effect in a new study. Sensitivity analysis to explore robustness of statistical and clinical assumptions will be carried out. Minor study effects (potential publication bias) will be investigated using funnel plots. A decision analytical model for use in low-income and middle-income countries will assess the cost-effectiveness of calcium supplementation to prevent pre-eclampsia. ETHICS AND DISSEMINATION: No ethical approvals are required. We will store the data in a secure repository in an anonymised format. The results will be published in peer-reviewed journals.

RESUMO

BACKGROUND: The COVID-19 pandemic increased maternal distress and demand for social support and educational services, while restriction measures decreased the availability of these services. PROJECT DESCRIPTION: The Godmother Project, a person-centered, WhatsApp-based support and health education initiative, was created after all in-person perinatal educational activities offered at 3 Brazilian hospitals were canceled in 2020. The project was developed in response to pregnant/postpartum women who called the hospitals with questions for health care professionals (HCPs). Health education nurses teamed up with staff from the communication department to design a project to (1) provide a direct communication channel between women and HCPs to answer health-related questions, (2) offer reliable virtual health education material, (3) identify women in need of additional assessment/referrals, (4) offer each woman continuous support from a specific nurse educator (Godmother), and (5) offer a virtual forum where women going through similar experiences could interact. PROJECT DEVELOPMENT AND ROLLOUT: The project provides direct communication between WhatsApp groups of 25-30 pregnant/postpartum women and a Godmother. It also offers access to a virtual library of educational materials prepared in response to women's needs/demands. The project, which began in July 2020 with 1 WhatsApp group of 5 women and 1 Godmother, currently has 305 groups, 6,942 active participants, and 4 Godmothers. Enrollments and WhatsApp groups continued to increase despite reestablishment of in-person educational activities in 2022. The vast majority of 232 participants surveyed in December 2021 were very satisfied with the project, the Godmothers, and the educational materials. CONCLUSIONS: Our findings suggest that WhatsApp groups of pregnant/postpartum women led by dedicated nurse educators can be an important tool to educate and support women during the perinatal period. This type of initiative may be especially important in contexts of physical distancing requirements or situations where social support is unavailable.

RESUMO

OBJECTIVE: The purpose of this study was to estimate the global distribution and financial cost associated with the inequities present in the use of cesarean sections (CS) worldwide. STUDY DESIGN: We used the latest estimates on CS rates published by WHO and we adopted 10-15 % as the range of CS rates that are considered optimal for adequate use. We calculated the cost (in USD) to achieve CS rates of 10-15 % for countries that reported rates below 10 %. We also calculated the cost of CS rates in excess (>15 % and > 20 %) by estimating how much it would cost to reduce the rates to 10-15 % for each of those countries. RESULTS: 137 countries are included in this analysis with updated data on CS rates between the years 2010 and 2018. Our analysis found that 36 countries reported CS rates < 10 %, whereas 91 countries reported CS rates > 15 % (a majority of which were > 20 %); only 10 countries reported CS rates between 10 and 15 %. The cost of CS exceeding a rate of 15 % is estimated to be $9,586,952,466 including inflation and exceeding 20 % is $7.169.248.033 (USD). The cost of achieving "needed" CS among countries with CS rates < 10 % is $612,609,418 (USD). The cost of cesarean sections exceeding 15 % has increased by 313 % between 2008 and more recent years, accruing $7 billion (USD) more in surplus since 2008. The reallocation of CS funding would save the global economy $9 billion (USD). CONCLUSION: Global inequities in CS performed and associated costs have increased since 2008, resulting in a disproportionate number of resources allocated.

RESUMO

BACKGROUND: Although caesarean section (CS) rates have increased rapidly in Thailand, the upward trend is not supported by significant maternal or perinatal health benefits. The appropriate use of CS through QUALIty DECision-making by women and providers (QUALI-DEC project) aims to design and implement a strategy to optimize the use of CS through non-clinical interventions. This study aimed to explore the factors influencing women's and health professionals' preferences for CS delivery in Thailand. METHODS: We conducted a formative qualitative study by using semi-structured in-depth interviews with pregnant and postpartum women, and healthcare staff. Purposive sampling was used to recruit participants from eight hospitals across four regions of Thailand. Content analysis was used to develop the main themes. RESULTS: There were 78 participants, including 27 pregnant and 25 postpartum women, 8 administrators, 13 obstetricians, and 5 interns. We identified three main themes and seven sub-themes of women and healthcare providers' perceptions on CS: (1) avoiding the negative experiences from vaginal birth (the pain of labor and childbirth, uncertainty during the labor period); (2) CS is a safer mode of birth (guarantees the baby's safety, a protective shield for doctors); and (3) CS facilitates time management (baby's destiny at an auspicious time, family's management, manage my work/time). CONCLUSIONS: Women mentioned negative experiences and beliefs about vaginal delivery, labor pain, and uncertain delivery outcomes as important factors influencing CS preferences. On the other hand, CS is safer for babies and facilitates multiple tasks in women's lives. From health professionals' perspectives, CS is the easier and safer method for patients and them. Interventions to reduce unnecessary CS, including QUALI-DEC, should be designed and implemented, taking into consideration the perceptions of both women and healthcare providers.
