The Yin and Yang of the oxytocin and stress systems: opposites, yet interdependent and intertwined determinants of lifelong health trajectories

During parturition and the immediate post-partum period there are two opposite, yet interdependent and intertwined systems that are highly active and play a role in determining lifelong health and behaviour in both the mother and her infant: the stress and the anti-stress (oxytocin) system. Before attempting to understand how the environment around birth determines long-term health trajectories, it is essential to understand how these two systems operate and how they interact. Here, we discuss together the hormonal and neuronal arms of both the hypothalamic-pituitary-adrenal (HPA) axis and the oxytocinergic systems and how they interact. Although the HPA axis and glucocorticoid stress axis are well studied, the role of oxytocin as an extremely powerful anti-stress hormone deserves more attention. It is clear that these anti-stress effects depend on oxytocinergic nerves emanating from the supraoptic nucleus (SON) and paraventricular nucleus (PVN), and project to multiple sites at which the stress system is regulated. These, include projections to corticotropin releasing hormone (CRH) neurons within the PVN, to the anterior pituitary, to areas involved in sympathetic and parasympathetic nervous control, to NA neurons in the locus coeruleus (LC), and to CRH neurons in the amygdala. In the context of the interaction between the HPA axis and the oxytocin system birth is a particularly interesting period as, for both the mother and the infant, both systems are very strongly activated within the same narrow time window. Data suggest that the HPA axis and the oxytocin system appear to interact in this early-life period, with effects lasting many years. If mother-child skin-to-skin contact occurs almost immediately postpartum, the effects of the anti-stress (oxytocin) system become more prominent, moderating lifelong health trajectories. There is clear evidence that HPA axis activity during this time is dependent on the balance between the HPA axis and the oxytocin system, the latter being reinforced by specific somatosensory inputs, and this has long-term consequences for stress reactivity.

Antenatal corticosteroids reduce neonatal mortality in settings without assisted ventilatory support: a retrospective cohort study of early preterm births on the Thailand-Myanmar border

Background

Prematurity is the highest risk for under-five mortality globally. The aim of the study was to assess the effect of antenatal dexamethasone on neonatal mortality in early preterm in a resource-constrained setting without assisted ventilation.

Methods

This retrospective (2008-2013) cohort study in clinics for refugees/migrants on the Thai-Myanmar border included infants born <34 weeks gestation at home, in, or on the way to the clinic. Dexamethasone, 24 mg (three 8 mg intramuscular doses, every 8 hours), was prescribed to women at risk of preterm birth (28 to <34 weeks). Appropriate newborn care was available: including oxygen but not assisted ventilation. Mortality and maternal fever were compared by the number of doses (complete: three, incomplete (one or two), or no dose). A sub-cohort participated in neurodevelopmental testing at one year.

Results

Of 15,285 singleton births, 240 were included: 96 did not receive dexamethasone and 144 received one, two or three doses (56, 13 and 75, respectively). Of live-born infants followed to day 28, (n=168), early neonatal and neonatal mortality/1,000 livebirths (95%CI) with complete dosing was 217 (121-358) and 304 (190-449); compared to 394 (289-511) and 521 (407-633) with no dose. Compared to complete dosing, both incomplete and no dexamethasone were associated with elevated adjusted ORs 4.09 (1.39 to 12.00) and 3.13 (1.14 to 8.63), for early neonatal death. By contrast, for neonatal death, while there was clear evidence that no dosing was associated with higher mortality, adjusted OR 3.82 (1.42 to 10.27), the benefit of incomplete dosing was uncertain adjusted OR 1.75 (0.63 to 4.81). No adverse impact of dexamethasone on infant neurodevelopmental scores (12 months) or maternal fever was observed.

Conclusions

Neonatal mortality reduction is possible with complete dexamethasone dosing in pregnancies at risk of preterm birth in settings without capacity to provide assisted ventilation.

Intrapartum time intervals and transfer of nulliparae from community births to maternity care units in Germany

BACKGROUND

Over one-third of nulliparae planning births either at home or in freestanding midwife-led birthing centers (community births) in high-income countries are transferred during labor. Perinatal data are reported each year in Germany for women planning community birth. So far, data sets have not been linked to describe time-related factors associated with nulliparous transfer to hospital.

OBJECTIVES

To describe the prevalence of referral for nulliparae and assess maternal and labor characteristics associated with intrapartum transfer.

METHODS

Perinatal data from 2010 to 2015 were linked (n = 26,115). Women were reviewed with respect to international eligibility criteria for community birth; 1997 women were excluded (7.6%). Descriptive statistics were reported; unadjusted and adjusted odds ratios with 95% confidence intervals (CI) tested the predictive effect of demographic and labor factors on rates of intrapartum transfer.

RESULTS

One in three nulliparous women (30.6%) were transferred to hospital. Compared with community births, transferred women were significantly more likely to experience longer time intervals during labor: from rupture of membranes (ROM) until birth lasting 5 to 18 h (OR 6.05, CI 5.53-6.61) and 19 to 24 h (OR 10.83, CI 9.45-12.41) compared to one to 4 h; and from onset of labor until birth 11 to 24 h (OR 6.72, CI 6.24-7.23) and 25 to 29 h (OR 26.62, CI 22.77-31.11) compared to one to 10 h. When entering all factors into the model, we found the strongest predictors of transfer to be fetal distress, longer time intervals between ROM until birth and onset of labor until birth.

CONCLUSIONS

Nulliparous transfer rates were similar to rates in other high-income countries; 94% of referrals were non-urgent. Time was found to be an independent risk factor for the transfer of nulliparae planning community birth.

Measuring disrespect and abuse during childbirth in a high-resource country: Development and validation of a German self-report tool

INTRODUCTION

Increasing evidence on disrespect and abuse during childbirth has led to growing concern about the quality of care childbearing women are experiencing. To provide quantitative evidence of disrespect and abuse during childbirth services in Germany a validated measurement tool is needed.

RESEARCH AIM

The aim of this research project was the development and psychometric validation of a survey tool in the German language that measures disrespect and abuse of women during childbirth.

METHODS

A survey tool was created including the following measures: German adaptations of the short and long form of the "Mothers on Respect" (MOR) index (MOR-7 and MOR-G); the "Mothers' Autonomy in Decision Making" (MADM) scale; a mistreatment-index (MIST-I) comprising indicators of mistreatment during childbirth; and a set of items that measure experiences of discrimination during maternity care. Internal consistency reliability and construct validity of the scales were assessed using Cronbach's alpha, unweighted least squares factor analysis and non-parametric correlation analysis with a scale that measures a related construct, the Posttraumatic Symptom Scale - Self Report (PSS-SR) scale. We distributed the survey online, recruiting through snowball sampling via social media. A selection bias towards women who had experienced disrespect and abuse during their birth was intended and expedient for tool validation. The final sample of participants (n = 2045) had given birth in Germany between 2009 and 2018.

FINDINGS

More than 77% of the study participants reported at least one form of mistreatment with non-consented care being the most commonly reported type of mistreatment, followed by physical violence, violation of physical privacy, verbal abuse and neglect. All included scales showed good psychometric properties with high Cronbach's alphas (0.95 for both MOR versions and 0.96 for MADM). Factor analysis generated one factor scales with high factor loadings (0.75 to 0.92 for MOR-7; 0.37 to 0.90 for MOR-G and 0.83 to 0.92 for MADM). MOR-7, MOR-G, MADM and MIST-I scores were significantly (p<0.001) correlated with PSS-SR scores (Spearman's rho -0.70, -0.61 and 0.68 for MOR-G, MADM and the MIST-I, respectively).

CONCLUSIONS

This study presents a valid and reliable instrument for the quantitative assessment of disrespect and abuse during childbirth in Germany. Childbearing women's experiences of disrespect and abuse are a relevant phenomenon in German hospital based maternity care. Disrespect and abuse during childbirth appear to contribute to post-traumatic symptoms and may be associated with severe mental health problems postpartum.

Describing the transition from late pregnancy into early labour - A prospective cohort study

OBJECTIVE

The time between self-assessed first symptoms and clinical confirmation of labour onset is marked by uncertainty, particularly for primiparas. Accordingly, primiparas often seek professional care to confirm their perceptions of labour onset. This paper describes the transition into early labour among primiparas considering their level of certainty in labour onset and their perception of labour onset symptoms prior to birth.

METHODS

A prospective exploratory cohort study was conducted in Germany between July 2020 - March 2021 among a convenience sample of 69 primiparas. Respondents recorded in a non-validated questionnaire their perceptions of nine symptoms and degree of certainty about labour onset every day from 37 weeks gestation. Descriptive analysis included certainty in labour onset and dedicated symptoms in relation to days before birth.

RESULTS

The participants (n=69) reported a little certainty of labour onset up to 32 days before birth and most of them became certain up to four days before birth. Associated symptoms were regular and irregular pain, symptoms of vaginal loss and emotional symptoms. Gastrointestinal symptoms and nausea were not indicated by a majority. Uncertainty of labour onset, however, was indicated up until the day of birth.

CONCLUSION

Although interpretation is based on a small sample size, primiparas are able to self-diagnose labour onset and report connected symptoms up to four days before birth. We suggest calling this time between self-diagnosis of labour onset and confirmed labour onset based on clinical parameters the transition into early labour.

Midwifery care providers' childbirth and immediate newborn care competencies: A cross-sectional study in Benin, Malawi, Tanzania and Uganda

Evidence-based quality care is essential for reducing sub-Saharan Africa's high burden of maternal and newborn mortality and morbidity. Provision of quality care results from interaction between several components of the health system including competent midwifery care providers and the working environment. We assessed midwifery care providers' ability to provide quality intrapartum and newborn care and selected aspects of the working environment as part of the Action Leveraging Evidence to Reduce perinatal morTality and morbidity (ALERT) project in Benin, Malawi, Tanzania, and Uganda. We used a self-administered questionnaire to assess provider knowledge and their working environment and skills drills simulations to assess skills and behaviours. All midwifery care providers including doctors providing midwifery care in the maternity units were invited to take part in the knowledge assessment and one third of the midwifery care providers who took part in the knowledge assessment were randomly selected and invited to take part in the skills and behaviour simulation assessment. Descriptive statistics of interest were calculated. A total of 302 participants took part in the knowledge assessment and 113 skills drills simulations were conducted. The assessments revealed knowledge gaps in frequency of fetal heart rate monitoring and timing of umbilical cord clamping. Over half of the participants scored poorly on aspects related to routine admission tasks, clinical history-taking and rapid and initial assessment of the newborn, while higher scores were achieved in active management of the third stage of labour. The assessment also identified a lack of involvement of women in clinical decision-making. Inadequate competency level of the midwifery care providers may be due to gaps in pre-service training but possibly related to the structural and operational facility characteristics including continuing professional development. Investment and action on these findings are needed when developing and designing pre-service and in-service training. Trial registration: PACTR202006793783148-June 17th, 2020.

Unplanned visits and midwife-led antenatal care

INTRODUCTION

Midwives provide antenatal care to women to ensure the health of both mother and baby, according to women's needs. This study aims to investigate demographic and social, clinical and obstetrical factors that may be associated with unplanned visits to the emergency by nulliparous and multiparous women who received midwifery care during the antenatal period.

METHODS

This was a retrospective cohort study with data collection from medical records of the CHU Saint-Pierre hospital. A total of 971 women gave birth between 1 January and 31 December 2017 and received midwifery-led care during their pregnancy. Descriptive statistics and multivariable logistic regression models with 95% confidence intervals (95% CI) were performed separately for nulliparous and multiparous women.

RESULTS

For nulliparae (n=246), the odds of visiting emergency services during pregnancy were 1.45 times (95% CI: 1.08-2.27) higher in women with more previous pregnancies than women with less previous pregnancies, 3.57 times (95% CI: 1.43-11.11) more likely in women without than with high-level hypertension, and 1.09 times (95% CI: 1.01-1.25) more likely in women with less previous midwifery-led visits than women with more previous midwifery-led visits. For multiparae (n=444), the odds of visiting emergency services during pregnancy were 2.12 times (95% CI: 1.06-6.07) higher in women presenting risk factors at first consultation than women without such factors.

CONCLUSIONS

For nulliparous and multiparous women, some characteristics seem to be associated with unplanned visits. Spontaneous visits may be driven by a need for care perceived by women and/or their partner but not specifically by urgent or unfavorable medical conditions.

Do in-service training materials for midwifery care providers in sub-Saharan Africa meet international competency standards? A scoping review 2000-2020

BACKGROUND

Levels of maternal and neonatal mortality remain high in sub-Saharan Africa, with an estimated 66% of global maternal deaths occurring in this region. Many deaths are linked to poor quality of care, which in turn has been linked to gaps in pre-service training programmes for midwifery care providers. In-service training packages have been developed and implemented across sub-Saharan Africa in an attempt to overcome the shortfalls in pre-service training. This scoping review has aimed to summarize in-service training materials used in sub-Saharan Africa for midwifery care providers between 2000 and 2020 and mapped their content to the International Confederation of Midwives (ICM) Essential Competencies for Midwifery Practice.

METHODS

Searches were conducted for the years 2000-2020 in Cumulative Index of Nursing and Allied Health Literature, PubMed/MEDLINE, Social Science Citation Index, African Index Medicus and Google Scholar. A manual search of reference lists from identified studies and a search of grey literature from international organizations was also performed. Identified in-service training materials that were accessible freely on-line were mapped to the ICM Essential Competencies for midwifery practice.

RESULTS

The database searches identified 1884 articles after removing duplicates. After applying exclusion criteria, 87 articles were identified for data extraction. During data extraction, a further 66 articles were excluded, leaving 21 articles to be included in the review. From these 21 articles, six different training materials were identified. The grey literature yielded 35 training materials, bringing the total number of in-service training materials that were reviewed to 41. Identified in-service training materials mainly focused on emergency obstetric care in a limited number of sub-Saharan Africa countries. Results also indicate that a significant number of in-service training materials are not readily and/or freely accessible. However, the content of in-service training materials largely met the ICM Essential Competencies, with gaps noted in the aspect of woman-centred care and shared decision making.

CONCLUSION

To reduce maternal and newborn morbidity and mortality midwifery care providers should have access to evidence-based in-service training materials that include antenatal care and routine intrapartum care, and places women at the centre of their care as shared decision makers.

Development and validation of a tool for advising primiparous women during early labour: study protocol for the GebStart Study

INTRODUCTION

Pregnant women experience early labour with different physical and emotional symptoms. Early admission to hospital has been found to be associated with increased intervention and caesarean section rates. However, primiparous women often contact the hospital before labour progresses because they encounter difficulties coping with symptoms of onset of labour on their own. An evidence-based instrument for assessing the individual needs to advise primiparous women during early labour is currently missing. The study aims to develop and validate a tool to inform the joint decision for or against hospital admission.

METHODS AND ANALYSIS

A scale development and validation study will be conducted including following steps: (1) Generation of a pool with 99 items based on a scoping review and focus group discussions with primiparous women, (2) Assessment of content and face validity by an expert panel and item reduction to 32 items, (3) Multicentre data collection in six study sites in Switzerland, with application of the preliminary tool and the validation items with a target sample size of approximately n=400 women and (4), item reduction using exploratory factor analysis, factor loading and item-to-item correlation. Internal consistency of the tool will be assessed using Cronbach's alpha and convergent validity computing correlations of items of the tool with the German versions of the Childbirth Self-Efficacy Inventory and the Cambridge-Worry Scale. Analyses will be performed using Stata V.17.

ETHICS AND DISSEMINATION

Ethical approval was obtained by the Ethics Committees Zurich and Northwestern and Central Switzerland (BASEC-Nr. 2021-00687). Results will be disseminated at the final study conference, at national and international congresses and by peer reviewed and not peer-reviewed articles in scientific and professional journals. Approved and anonymised data will be shared. The dissemination of the findings will have a contributable impact on clinical practice, scientific discussions and future research.

Are midwives ready to provide quality evidence-based care after pre-service training? Curricula assessment in four countries-Benin, Malawi, Tanzania, and Uganda

This research sought to map midwifery pre-service training curricula as part of the Action Leveraging Evidence to Reduce perinatal morTality and morbidity in sub-Saharan Africa (ALERT) project conducted in Benin, Malawi, Tanzania, and Uganda. We conducted the review in two phases. In the first phase, online interviews were performed with the lead project midwives in all four study countries to get an overview of midwifery care providers' pre-service training courses, registration, and licensing requirements. We performed a mapping review of midwifery care providers' pre-service training curricula from different training institutions in the four study countries during the second phase. Curricula were reviewed and mapped against the International Confederation of Midwives (ICM) Essential Competencies framework to assess whether these curricula included the minimum essential training components described in the ICM framework. We identified 10 different professional titles for midwifery care providers. The number of years spent in pre-service training varied from one and a half to four years. Ten pre-service curricula were obtained and the assessment revealed that none of the curricula included all ICM competencies. Main gaps identified in all curricula related to women-centred care, inclusion of women in decision making, provision of care to women with unintended or mistimed pregnancy, fundamental human rights of individuals and evidence-based learning. This review suggests that there are skills, knowledge and behaviour gaps in pre-service training curricula for midwifery care providers when mapped to the ICM Essential Competencies framework. These gaps are similar among the different training courses in participating countries. The review also draws attention to the plethora of professional titles and different pre-service training curricula within countries. Trial registration: PACTR202006793783148-June 17th, 2020.

Action leveraging evidence to reduce perinatal mortality and morbidity (ALERT): study protocol for a stepped-wedge cluster-randomised trial in Benin, Malawi, Tanzania and Uganda

Background

Insufficient reductions in maternal and neonatal deaths and stillbirths in the past decade are a deterrence to achieving the Sustainable Development Goal 3. The majority of deaths occur during the intrapartum and immediate postnatal period. Overcoming the knowledge-do-gap to ensure implementation of known evidence-based interventions during this period has the potential to avert at least 2.5 million deaths in mothers and their offspring annually. This paper describes a study protocol for implementing and evaluating a multi-faceted health care system intervention to strengthen the implementation of evidence-based interventions and responsive care during this crucial period.

Methods

This is a cluster randomised stepped-wedge trial with a nested realist process evaluation across 16 hospitals in Benin, Malawi, Tanzania and Uganda. The ALERT intervention will include four main components: i) end-user participation through narratives of women, families and midwifery providers to ensure co-design of the intervention; ii) competency-based training; iii) quality improvement supported by data from a clinical perinatal e-registry and iv) empowerment and leadership mentoring of maternity unit leaders complemented by district based bi-annual coordination and accountability meetings. The trial’s primary outcome is in-facility perinatal (stillbirths and early neonatal) mortality, in which we expect a 25% reduction. A perinatal e-registry will be implemented to monitor the trial. Our nested realist process evaluation will help to understand what works, for whom, and under which conditions. We will apply a gender lens to explore constraints to the provision of evidence-based care by health workers providing maternity services. An economic evaluation will assess the scalability and cost-effectiveness of ALERT intervention.

Discussion

There is evidence that each of the ALERT intervention components improves health providers’ practices and has modest to moderate effects. We aim to test if the innovative packaging, including addressing specific health systems constraints in these settings, will have a synergistic effect and produce more considerable perinatal mortality reductions.

Parents' experiences of care offered after stillbirth: An international online survey of high and middle-income countries

BACKGROUND

Stillbirth, the death of a baby before birth, is associated with significant psychological and social consequences that can be mitigated by respectful and supportive bereavement care. The absence of high-level evidence to support the broad scope of perinatal bereavement practices means that offering a range of options identified as valued by parents has become an important indicator of care quality. This study aimed to describe bereavement care practices offered to parents across different high-income and middle-income countries.

METHODS

An online survey of parents of stillborn babies was conducted between December 2014 and February 2015. Frequencies of nine practices were compared between high-income and middle-income countries. Differences in proportions of reported practices and their associated odds ratios were calculated to compare high-income and middle-income countries.

RESULTS

Over three thousand parents (3041) with a self-reported stillbirth in the preceding five years from 40 countries responded. Fifteen countries had atleast 40 responses. Significant differences in the prevalence of offering nine bereavement care practices were reported by women in high-income countries (HICs) compared with women in middle-income countries (MICs). All nine practices were reported to occur significantly more frequently by women in HICs, including opportunity to see and hold their baby (OR = 4.8, 95% CI 4.0-5.9). The widespread occurrence of all nine practices was reported only for The Netherlands.

CONCLUSIONS

Bereavement care after stillbirth varies between countries. Future research should look at why these differences occur, their impact on parents, and whether differences should be addressed, particularly how to support effective communication, decision-making, and follow-up care.

Challenges in using Mental Contrasting with Implementation Intentions (MCII) for preparation for natural birth: A feasibility study

OBJECTIVE

Women who plan a natural birth can benefit from strategies and/or resources that help them prepare for and cope with labour pain. This study aims to identify the feasibility of using Mental Contrasting with Implementation Intentions (MCII) for preparation of primiparous women for natural childbirth. Secondary aims are to test the acceptability of a health-focused information leaflet, and to describe how participants with high natural birth intentions cognitively prepare for birth.

METHODS

In third trimester, ten primiparous women participated in this interventional study with follow-up. A health-focused information leaflet on physiological childbirth, MCII, a mental strategy that helps people achieve a desired goal by envisioning obstacles and how to overcome them, and a researcher-developed questionnaire which contained the CBSEI-C32, was used. Survey data were analysed using a combination of descriptive statistics and deductive theoretical thematic analysis.

RESULTS

The health-focused leaflet was exclusively judged positively. Nine women did not use MCII as instructed, they did not find it helpful for childbirth preparation and wished to have a more positive, health-focused approach towards childbirth. Two themes emerged from the participants' responses: 'the ability to give birth' which was supported through childbirth preparedness, coping strategies, confidence and external supports and 'the uncertainty of giving birth' which included fears and worries about possible adverse events and the baby's health.

CONCLUSION

MCII was not a promising tool for natural childbirth preparation among primiparous women in Germany. Our findings show that women prefer a positive, health-focused approach, rather than thinking about overcoming obstacles, when they prepare for childbirth.

Challenges in applying the short Childbirth Self-Efficacy Inventory (CBSEI-C32) in German

INTRODUCTION

This study aimed to review and pilot-test feedback from childbearing women who completed the German short version of the Childbirth Self-Efficacy Inventory (CBSEI-C32), which is widely used and validated in different languages.

METHODS

Ten pregnant nulliparas, who planned a natural childbirth, completed the German CBSEI-C32 and provided comments about the comprehensibility of the tool.

RESULTS

When applying the standardized translated German CBSEI-C32, we discovered that women generally gave positive feedback, and reported that the items made them think about coping strategies for labor and birth. Some pregnant woman had problems in understanding two items: ‘Mich beherrschen’ (original English item: ‘Keep myself in control’), and ‘Mich ruhig halten’ (original English item: ‘Keep myself calm’). Some of the items were not comprehensible for pregnant women and might not represent contemporary concepts of childbirth self-efficacy.

CONCLUSIONS

Two items of the German CBSEI-C32 were interpreted ambiguously by the pilot testers. The CBSEI should be checked to identify which items could serve as the basis for a new questionnaire because there are clear and appropriate coping strategies when dealing with labour pain such as item 3 on breathing. These could be complemented with other coping behaviours that are positively worded and serve to empower rather than restrain women. For measuring self-efficacy beliefs in childbirth nowadays, it appears that health-oriented aspects, such as concentrating on the pauses between contractions or mentally staying in the present moment, are more important for women than focusing on control during childbirth.

Protocol for a scoping review to identify and map in-service education and training materials for midwifery care in sub-Saharan Africa from 2000 to 2020

INTRODUCTION

Maternal and neonatal mortality are disproportionally high in low-and middle-income countries. In 2017 the global maternal mortality ratio was estimated to be 211 per 100 000 live births. An estimated 66% of these deaths occurred in sub-Saharan Africa. Training programmes that aim to prepare providers of midwifery care vary considerably across sub-Saharan Africa in terms of length, content and quality. To overcome the shortfalls of pre-service training and support the provision of quality care, in-service training packages for providers of midwifery care have been developed and implemented in many countries in sub-Saharan Africa. We aim to identify what in-service education and training materials have been used for providers of midwifery care between 2000 and 2020 and map their content to the International Confederation of Midwives' Essential Competencies for Midwifery Practice (ICM Competencies), and the Lancet Midwifery Series Quality Maternal and Newborn Care (QMNC) framework.

METHODS AND ANALYSIS

A search will be conducted for the years 2000-2020 in Cumulative Index of Nursing and Allied Health Literature, PubMed/MEDLINE, Social Sciences Citation Index, African Index Medicus and Google Scholar. A manual search of reference lists from identified studies and a hand search of literature from international partner organisations will be performed. Information retrieved will include study context, providers trained, focus of training and design of training. Original content of identified education and training materials will be obtained and mapped to the ICM Competencies and the Lancet Series QMNC.

ETHICS AND DISSEMINATION

A scoping review is a secondary analysis of published literature and does not require ethical approval. This scoping review will give an overview of the education and training materials used for in-service training for providers of midwifery care in sub-Saharan Africa. Mapping the content of these education and training materials to the ICM Competencies and The Lancet Series QMNC will allow us to assess their appropriateness. Findings from the review will be reflected to stakeholders involved in the design and implementation of such materials. Additionally, findings will be published in a peer-reviewed journal, and used to inform the design and content of an in-service training package for providers of midwifery care as part of the Action Leveraging Evidence to Reduce perinatal morTality and morbidity (ALERT) study, (https://alert.ki.se/) a multi-country study in Benin, Malawi, Tanzania and Uganda.

Assessment of midwifery care providers intrapartum care competencies, in four sub-Saharan countries: a mixed-method study protocol

BACKGROUND

We aim to assess competencies (knowledge, skills and attitudes) of midwifery care providers as well as their experiences and perceptions of in-service training in the four study countries; Benin, Malawi, Tanzania and Uganda as part of the Action Leveraging Evidence to Reduce perinatal mortality and morbidity in sub-Saharan Africa project (ALERT). While today more women in low- and middle-income countries give birth in health care facilities, reductions in maternal and neonatal mortality have been less than expected. This paradox may be explained by the standard and quality of intrapartum care provision which depends on several factors such as health workforce capacity and the readiness of the health system as well as access to care.

METHODS

Using an explanatory sequential mixed method design we will employ three methods (i) a survey will be conducted using self-administered questionnaires assessing knowledge, (ii) skills drills assessing basic intrapartum skills and attitudes, using an observation checklist and (iii) Focus Group Discussions (FGDs) to explore midwifery care providers' experiences and perceptions of in-service training. All midwifery care providers in the study facilities are eligible to participate in the study. For the skills drills a stratified sample of midwifery care providers will be selected in each hospital according to the number of providers and, professional titles and purposive sampling will be used for the FGDs. Descriptive summary statistics from the survey and skills drills will be presented by country. Conventional content analysis will be employed for data analysis of the FGDs.

DISCUSSION

We envision comparative insight across hospitals and countries. The findings will be used to inform a targeted quality in-service training and quality improvement intervention related to provision of basic intrapartum care as part of the ALERT project.

Are There Epigenetic Oxytocin-Mediated Effects on the Mother and Infant during Physiological Childbirth?

INTRODUCTION

Studies have shown that long-term positive behavioural and physiological changes are induced in connection with vaginal, physiological birth, and skin-to-skin contact after birth in mothers and babies. Some of these effects are consistent with the effect profile of oxytocin. This scoping review explores whether epigenetic changes of the oxytocin gene and of the oxytocin receptor gene (OTR) are involved in these effects.

METHODS

We searched Pubmed, Medline, BioMed Central, Cochrane Library, OVID, and Web of Science for evidence of epigenetic changes in connection with childbirth in humans, with a particular focus on the oxytocin system.

RESULTS

There were no published studies identified that were related to epigenetic changes of oxytocin and its receptor in connection with labour, birth, and skin-to-skin contact after birth in mothers and babies. However, some studies were identified that showed polymorphisms of the oxytocin receptor influenced the progress of labour. We also identified studies in which the level of global methylation was measured in vaginal birth and caesarean section, with conflicting results. Some studies identified differences in the level of methylation of single genes linked to various effects, for example, immune response, metabolism, and inflammation. In some of these cases, the level of methylation was associated with the duration of labour or mode of birth. We also identified some studies that demonstrated long-term effects of mode of birth and of skin-to-skin contact linked to changes in oxytocin function.

CONCLUSION

There were no studies identified that showed epigenetic changes of the oxytocin system in connection with physiological birth. The lack of evidence, so far, regarding epigenetic changes did not exclude future demonstrations of such effects, as there was a definite role of oxytocin in creating long-term effects during the perinatal period. Such studies may not have been performed. Alternatively, the oxytocin linked effects might be indirectly mediated via other receptors and signalling systems. We conclude that there is a significant lack of research examining long-term changes of oxytocin function and long-term oxytocin mediated adaptive effects induced during physiological birth and skin-to-skin contact after birth in mothers and their infants.

Data on oxytocin IU dose, infusion fluid amount, start dose, escalation rate and maximum dose were collected. Values for each regimen were converted to IU in 1000ml diluent. One IU corresponded to 1.67μg for doses provided in grams/micrograms. IU hourly dose increase rates were based on escalation frequency. Cumulative doses and total IU amount infused were calculated by adding the dose administered for each previous hour. Main Outcome Measures Oxytocin IU dose infused

Results

Data were obtained on 21 regimens used in 12 countries. Details on the start dose, escalation interval, escalation rate and maximum dose infused were available from 16 regimens. Starting rates varied from 0.06 IU/hour to 0.90 IU/hour, and the maximum dose rate varied from 0.90 IU/hour to 3.60 IU/hour. The total amount of IU oxytocin infused, estimated over eight hours, ranged from 2.38 IU to 27.00 IU, a variation of 24.62 IU and an 11-fold difference.

Conclusion

Current variations in oxytocin regimens for induction and augmentation of labour are inexplicable. It is crucial that the appropriate minimum infusion regimen is administered because synthetic oxytocin is a potentially harmful medication with serious consequences for women and babies when inappropriately used. Estimating the total amount of oxytocin IU received by labouring women, alongside the institution’s mode of birth and neonatal outcomes, may deepen our understanding and be the way forward to identifying the optimal infusion regimen.

Variations in use of childbirth interventions in 13 high-income countries: A multinational cross-sectional study

BACKGROUND

Variations in intervention rates, without subsequent reductions in adverse outcomes, can indicate overuse. We studied variations in and associations between commonly used childbirth interventions and adverse outcomes, adjusted for population characteristics.

METHODS AND FINDINGS

In this multinational cross-sectional study, existing data on 4,729,307 singleton births at ≥37 weeks in 2013 from Finland, Sweden, Norway, Denmark, Iceland, Ireland, England, the Netherlands, Belgium, Germany (Hesse), Malta, the United States, and Chile were used to describe variations in childbirth interventions and outcomes. Numbers of births ranged from 3,987 for Iceland to 3,500,397 for the USA. Crude data were analysed in the Netherlands, or analysed data were shared with the principal investigator. Strict variable definitions were used and information on data quality was collected. Intervention rates were described for each country and stratified by parity. Uni- and multivariable analyses were performed, adjusted for population characteristics, and associations between rates of interventions, population characteristics, and outcomes were assessed using Spearman's rank correlation coefficients. Considerable intercountry variations were found for all interventions, despite adjustments for population characteristics. Adjustments for ethnicity and body mass index changed odds ratios for augmentation of labour and episiotomy. Largest variations were found for augmentation of labour, pain relief, episiotomy, instrumental birth, and cesarean section (CS). Percentages of births at ≥42 weeks varied from 0.1% to 6.7%. Rates among nulliparous versus multiparous women varied from 56% to 80% versus 51% to 82% for spontaneous onset of labour; 14% to 36% versus 8% to 28% for induction of labour; 3% to 13% versus 7% to 26% for prelabour CS; 16% to 48% versus 12% to 50% for overall CS; 22% to 71% versus 7% to 38% for augmentation of labour; 50% to 93% versus 25% to 86% for any intrapartum pain relief, 19% to 83% versus 10% to 64% for epidural anaesthesia; 6% to 68% versus 2% to 30% for episiotomy in vaginal births; 3% to 30% versus 1% to 7% for instrumental vaginal births; and 42% to 70% versus 50% to 84% for spontaneous vaginal births. Countries with higher rates of births at ≥42 weeks had higher rates of births with a spontaneous onset (rho = 0.82 for nulliparous/rho = 0.83 for multiparous women) and instrumental (rho = 0.67) and spontaneous (rho = 0.66) vaginal births among multiparous women and lower rates of induction of labour (rho = -0.71/-0.66), prelabour CS (rho = -0.61/-0.65), overall CS (rho = -0.61/-0.67), and episiotomy (multiparous: rho = -0.67). Variation in CS rates was mainly due to prelabour CS (rho = 0.96). Countries with higher rates of births with a spontaneous onset had lower rates of emergency CS (nulliparous: rho = -0.62) and higher rates of spontaneous vaginal births (multiparous: rho = 0.70). Prelabour and emergency CS were positively correlated (nulliparous: rho = 0.74). Higher rates of obstetric anal sphincter injury following vaginal birth were found in countries with higher rates of spontaneous birth (nulliparous: rho = 0.65). In countries with higher rates of epidural anaesthesia (nulliparous) and spontaneous births (multiparous), higher rates of Apgar score < 7 were found (rhos = 0.64). No statistically significant variation was found for perinatal mortality. Main limitations were varying quality of data and missing information.

CONCLUSIONS

Considerable intercountry variations were found for all interventions, even after adjusting for population characteristics, indicating overuse of interventions in some countries. Multivariable analyses are essential when comparing intercountry rates. Implementation of evidence-based guidelines is crucial in optimising intervention use and improving quality of maternity care worldwide.

First assessed cervical dilatation: is it associated with oxytocin augmentation during labour? A retrospective cohort study in a university hospital in Switzerland

OBJECTIVES

The primary objective of this study was to examine the association between the first assessed cervical dilatation in a labourward and the use of oxytocin augmentation during labour. Further analysis was performed by examining the actual stage of labour at the point oxytocin was first administered to those women.

DESIGN

Retrospective cohort study with the data collected from the medical records of the hospital.

SETTING

University Hospital Bern, Switzerland PARTICIPANTS: 1933 term nulliparous and multiparous women with a singleton pregnancy giving birth during the period June 2013 and May 2017, representing Robson groups 1 and 3.

MEASUREMENTS AND FINDINGS

Descriptive statistics and multivariable logistic regression models were performed. It was found that for the entire process of labour, nulliparous and multiparous women (n = 1933) with a first cervical dilatation of 5 or more cm were less likely to be augmented with oxytocin (OR 0.64, 95% CI 0.46; 0.88 and OR 0.56, 95% CI 0.38; 0.82, respectively) compared to women with a first cervical dilatation of less than 5 cm. Out of these augmented women (n = 746) having a first cervical dilatation of 5 or more cm, they had a lower likelihood of being augmented during the first stage of labour compared to women with a first cervical dilatation of less than 5 cm (OR 0.45, 95% CI 0.29; 0.7 for nulliparae and OR 0.32, 95% CI 0.16; 0.6 for multiparae). Additionally, it was observed that other factors contributed to the application of oxytocin. One such example was that epidural analgesia was associated with a high risk of oxytocin augmentation in nulliparae (OR 13.88, 95% CI 9.29; 20.74) and multiparae (OR 15.52, 95% CI 9.94; 24.22). The application of oxytocin was also found to affect the caesarean section rate in nulliparous and multiparous women as it was 20% and 13% respectively for those with oxytocin versus 13% and 4% respectively for those without oxytocin.

KEY CONCLUSIONS

Early admission to the labourward is associated with an increased use of oxytocin to augment labour, particularly, during the first stage of labour. Epidural analgesia is a main predictor for oxytocin augmentation in nulliparous and multiparous women.

IMPLICATIONS FOR PRACTICE

Pregnant women warrant more appropriate support during early labour, avoiding early maternal exhaustion and excessive obstetrical interventions.

OptiBIRTH: a cluster randomised trial of a complex intervention to increase vaginal birth after caesarean section

BACKGROUND

Despite evidence supporting the safety of vaginal birth after caesarean section (VBAC), rates are low in many countries.

METHODS

OptiBIRTH investigated the effects of a woman-centred intervention designed to increase VBAC rates through an unblinded cluster randomised trial in 15 maternity units with VBAC rates < 35% in Germany, Ireland and Italy. Sites were matched in pairs or triplets based on annual birth numbers and VBAC rate, and randomised, 1:1 or 2:1, intervention versus control, following trial registration. The intervention involved evidence-based education of clinicians and women with one previous caesarean section (CS), appointment of opinion leaders, audit/peer review, and joint discussions by women and clinicians. Control sites provided usual care. Primary outcome was annual hospital-level VBAC rates before the trial (2012) versus final year of the trial (2016). Between April 2014 and October 2015, 2002 women were recruited (intervention 1195, control 807), with mode-of-birth data available for 1940 women.

RESULTS

The OptiBIRTH intervention was feasible and safe across hospital settings in three countries. There was no statistically significant difference in the change in the proportion of women having a VBAC between intervention sites (25.6% in 2012 to 25.1% in 2016) and control sites (18.3 to 22.3%) (odds ratio adjusted for differences between intervention and control groups (2012) and for homogeneity in VBAC rates at sites in the countries: 0.87, 95% CI: 0.67, 1.14, p = 0.32 based on 5674 women (2012) and 5284 (2016) with outcome data. Among recruited women with birth data, 4/1147 perinatal deaths > 24 weeks gestation occurred in the intervention group (0.34%) and 4/782 in the control group (0.51%), and two uterine ruptures (one per group), a rate of 1:1000.

CONCLUSIONS

Changing clinical practice takes time. As elective repeat CS is the most common reason for CS in multiparous women, interventions that are feasible and safe and that have been shown to lead to decreasing repeat CS, should be promoted. Continued research to refine the best way of promoting VBAC is essential. This may best be done using an implementation science approach that can modify evidence-based interventions in response to changing clinical circumstances.

TRIAL REGISTRATION

The OptiBIRTH trial was registered on 3/4/2013. Trial registration number ISRCTN10612254.

Changing behaviour in pregnant women: A scoping review

OBJECTIVES

Behaviour change programmes (BCPs) for pregnant women are frequently implemented as part of health promotion initiatives. At present, little is known about the types of behaviour change programmes that are being implemented and whether these programmes are designed and delivered in accordance with the principles of high quality maternity care. In this scoping review, we provide an overview of existing interventions related to behaviour change in pregnancy with a particular emphasis on programmes that include empowerment components to promote autonomy and woman-led decision-making.

METHODS

A systematic search strategy was applied to check for relevant papers in August 2017 and again in October 2018.

RESULTS

Thirty studies met the criteria for inclusion. These studies addressed weight management, smoking cessation, general health education, nutrition, physical activity, alcohol consumption and dental health. The main approach was knowledge gain through education. More than half of the studies (n = 17) included three or more aspects of empowerment as part of the intervention. The main aspect used to foster women`s empowerment was skills and competencies. In nine studies midwives were involved, but not as programme leaders.

CONCLUSIONS

Education for knowledge gain was found to be the prevailing approach in behaviour change programmes. Empowerment aspects were not a specific focus of the behaviour change programmes. This review draws attention to the need to design interventions that empower women, which may be beneficial through their live. As midwives provide maternal healthcare worldwide, they are well-suited to develop, manage, implement or assist in BCPs.

A Survey of University Students' Preferences for Midwifery Care and Community Birth Options in 8 High-Income Countries

INTRODUCTION

Midwifery care is associated with positive birth outcomes, access to community birth options, and judicious use of interventions. The aim of this study was to characterize and compare maternity care preferences of university students across a range of maternity care systems and to explore whether preferences align with evidence-based recommendations and options available.

METHODS

A cross-sectional, web-based survey was completed in 2014 and 2015 by a convenience sample of university students in 8 high-income countries across 4 continents (N = 4569). In addition to describing preferences for midwifery care and community birth options across countries, this study examined sociodemographic characteristics, psychological factors, knowledge about pregnancy and birth, and sources of information that shaped students' attitudes toward birth in relation to preferences for midwifery care and community birth options.

RESULTS

Approximately half of the student respondents (48.2%) preferred midwifery-led care for a healthy pregnancy; 9.5% would choose to give birth in a birthing center, and 4.5% preferred a home birth. Preference for midwifery care varied from 10.3% among women in the United States to 78.6% among women in the United Kingdom. Preferences for home birth varied from 0.3% among US women to 18.3% among Canadian women. Women, health science students, those with low childbirth fear, those who learned about pregnancy and birth from friends (compared with other sources, eg, the media), and those who responded from Europe were significantly more likely to prefer midwifery care and community birth. High confidence in knowledge of pregnancy and birth was linked to significantly higher odds of community birth preferences and midwifery care preferences.

DISCUSSION

It would be beneficial to integrate childbirth education into high school curricula to promote knowledge of midwifery care, pregnancy, and childbirth and to reduce fear among prospective parents. Community birth options need to be expanded to meet demand among the next generation of maternity service users.

Preference of birth mode and postnatal health related quality of life after one previous caesarean section in three European countries

OBJECTIVES

Women who have had a caesarean section may have a preference for birth mode during their subsequent pregnancy, either 'vaginal birth after caesarean' (VBAC) or 'elective repeat caesarean section' (ERCS). A mismatch between the preferred and actual birth mode may result in an impaired postnatal Health Related Quality of Life (HRQoL). This study examined the associations between antenatal birth mode preferences, the actual birth mode and postnatal HRQoL in women with one previous caesarean section in three European countries.

DESIGN

Prospective longitudinal survey, as a part of a cluster randomised trial (OptiBIRTH) SETTING: Fifteen maternity units in three European countries: Germany (5), Ireland (5) and Italy (5).

PARTICIPANTS

Women (≥ aged 18 years) living in Germany, Ireland and Italy with one previous caesarean section. The sample consisted of 862 women with complete antenatal and postpartum data.

MEASUREMENTS

Women's preference for birth mode after one previous caesarean section was assessed at inclusion to the trial, and HRQoL was assessed antenatally and at three months postpartum using the Short-Form Six-Dimension health survey. Based on women's preferences and actual birth mode six groups were determined: "match VBAC-VBAC" (preference for vaginal birth, actual mode of birth vaginal birth), "match ERCS-ERCS" (preference for caesarean section, actual mode of birth elective repeat caesarean section), "match ERCS-EMCS" (preference for caesarean section, actual mode of birth emergency repeat caesarean section), "mismatch VBAC-ERCS" (preference for vaginal birth, actual mode of birth elective repeat caesarean section), "mismatch VBAC-EMCS" (preference for vaginal birth, actual mode of birth emergency repeat caesarean section) and "no preference". Associations between the preferred and actual birth mode were examined using univariate and multivariate analyses.

FINDINGS

Women with preference for vaginal birth but who gave birth by elective repeat caesarean section (mismatch VBAC-ERCS) had a lower postnatal HRQoL compared to women with a preference for vaginal birth who actually had a birth vaginally (match VBAC-VBAC, p = 0.02). Poor antenatal HRQoL scores (p < 0.01) and maternal readmission postpartum (p = 0.03) are cofounding factors for poorer postnatal HRQoL scores.

KEY CONCLUSIONS

The results show that women with a preference for a vaginal birth who gave birth by an elective repeat caesarean section had a significantly lower HRQoL at three months postnatal. The long-term consequences and psychological health of women who do not achieve a vaginal birth after caesarean require further consideration and research.

IMPLICATIONS FOR PRACTICE

Attention should be given to the long-term impact of a mismatch in preferred and actual mode on the psychological health of women.

Inter-institutional variations in oxytocin augmentation during labour in German university hospitals: a national survey

BACKGROUND

There are several international guidelines on oxytocin regimens for induction and augmentation of labour, but no agreement on a standardised regimen in Germany. This study collated and reviewed the oxytocin regimens used for labour augmentation in university hospitals, with the long-term aim of contributing to the development of a national clinical guideline.

METHODS

Germany has 34 university hospital compounds, representing 39 maternity units. In this observational study we asked units to provide standard operational procedures on oxytocin augmentation during labour or provide the details in a structured survey. Data were collected on the dosage of oxytocin, type and volume of solutions used, indications and contraindications for use and discontinuation, case-specific administration, and on who developed the procedures. Findings were analysed descriptively.

RESULTS

A total of 35 (90%) units participated in this study. Standard operating procedures were available in 24 units (69%), seven units (20%) did not have procedures and information was missing from four units (11%). Midwives participated in the development of standard operating procedures in 15 units (43%). Infusions were most commonly prepared using six units of oxytocin in 500 ml 0.9% normal saline solution (12 mU/ml). The infusions were started at 120 mU/hour and increased by 120 mU/hour at 20-min intervals up to a maximum dosage of 1200 mU/hour. The most common indication for use was delayed progress in labour. Infusions were stopped when uterine contractions became hypertonic and/or the fetal heart rate showed signs of distress. Most of the practices described aligned with international guidance. All units used reduced oxytocin dosages for women with a history of previous caesareans section, as recommended in the international guidelines, and restrictive use was advised in multiparous women. The main difference between units related to combined use of amniotomy and oxytocin, recommended by three guidelines but used in only four maternity units (11%).

CONCLUSIONS

While there was considerable variation in the oxytocin augmentation procedures, most but not all practices used in these 35 German maternity units were comparable. Establishing a national guideline on the criteria for and administration of oxytocin for augmentation of labour would eliminate the observed differences and minimise risk of administration and medication error.

Health economic analysis of a cluster-randomised trial (OptiBIRTH) designed to increase rates of vaginal birth after caesarean section

OBJECTIVE

To perform a health economic analysis of an intervention designed to increase rates of vaginal birth after caesarean, compared with usual care.

DESIGN

Economic analysis alongside the cluster-randomised OptiBIRTH trial (Optimising childbirth by increasing vaginal birth after caesarean section (VBAC) through enhanced women-centred care).

SETTING

Fifteen maternity units in three European countries - Germany (five), Ireland (five), and Italy (five) - with relatively low VBAC rates.

POPULATION

Pregnant women with a history of one previous lower-segment caesarean section; sites were randomised (3:2) to intervention or control.

METHODS

A cost-utility analysis from both societal and health-services perspectives, using a decision tree.

MAIN OUTCOME MEASURES

Costs and resource use per woman and infant were compared between the control and intervention group by country, from pregnancy recognition until 3 months postpartum. Based on the caesarean section rates, and maternal and neonatal morbidities and mortality, the incremental cost-utility ratios were calculated per country.

RESULTS

The mean difference in costs per quality-adjusted life years (QALYs) gained from a societal perspective between the intervention and the control group, using a probabilistic sensitivity analysis, was: €263 (95% CI €258-268) and 0.008 QALYs (95% CI 0.008-0.009 QALYs) for Germany, €456 (95% CI €448-464) and 0.052 QALYs (95% CI 0.051-0.053 QALYs) for Ireland, and €1174 (95% CI €1170-1178) and 0.006 QALYs (95% CI 0.005-0.007 QALYs) for Italy. The incremental cost-utility ratios were €33,741/QALY for Germany, €8785/QALY for Ireland, and €214,318/QALY for Italy, with a 51% probability of being cost-effective for Germany, 92% for Ireland, and 15% for Italy.

CONCLUSION

The OptiBIRTH intervention was likely to be cost-effective in Ireland and Germany.

TWEETABLE ABSTRACT

The OptiBIRTH intervention (to increase VBAC rates) is likely to be cost-effective in Germany and Ireland.

Labour characteristics of women achieving successful vaginal birth after caesarean section in three European countries

OBJECTIVE

Knowledge about labour characteristics of women achieving successful vaginal birth after caesarean section (VBAC) might be used to improve labour and birth management. This study examined sociodemographic and labour process-related factors regarding a) differences between countries, b) the comparison of successful VBAC with unplanned caesarean section, and c) predictors for the success of planned VBAC in three European countries.

DESIGN

We analysed observational data collected within the OptiBIRTH trial, a cluster-randomised controlled trial.

SETTING

Fifteen study sites in Ireland, Italy and Germany, five in each country.

PARTICIPANTS

790 participants going into labour for planned VBAC.

MEASUREMENTS

Descriptive statistics and random-effects logistic regression models were applied.

FINDINGS

The pooled successful VBAC-rate was 74.6%. Italy had the highest proportion of women receiving none of the four intrapartum interventions amniotomy (ARM), oxytocin, epidural or opioids (42.5% vs Ireland: 26.8% and Germany: 25.3%, p < 0.001). Earlier performance of ARM was associated with successful VBAC (3.50 hrs vs 6.08 hrs, p = 0.004). A positive predictor for successful vaginal birth was a previous vaginal birth (OR=3.73, 95% CI [2.17, 6.44], p < 0.001). The effect of ARM increased with longer labour duration (OR for interaction term=1.06, 95% CI [1.004, 1.12], p = 0.035). Higher infant birthweight (OR per kg=0.34, 95% CI [0.23, 0.50], p < 0.001), ARM (reference spontaneous rupture of membranes (SROM), OR=0.20, 95% CI [0.11, 0.37], p < 0.001) and a longer labour duration (OR per hour=0.93, 95% CI [0.90, 0.97], p < 0.001) decreased the odds of a vaginal birth.

KEY CONCLUSION

Women with a previous vaginal birth, an infant with a lower birth weight, SROM and a shorter labour duration were most likely to have a successful vaginal birth. If SROM did not occur, an earlier ARM increased the odds of a vaginal birth.

IMPLICATION FOR PRACTICE

Labour progress should be accelerated by fostering endogenous uterine contractions. With slow labour progress and intact membranes, ARM might increase the chance of a vaginal birth.

Association between increased antenatal vaginal pH and preterm birth rate: a systematic review

Background Worldwide, 14.9 million infants (11%) are born preterm each year. Up to 40% of preterm births (PTBs) are associated with genital tract infections. The vaginal pH can reflect changes in the vaginal milieu and, if elevated, indicates an abnormal flora or infection. Objective The aim of the study was to investigate whether an increased antenatal vaginal pH >4.5 in pre-labour pregnant women is associated with an increased PTB rate <37 completed weeks gestation. Search strategy Key databases included SCOPUS, EMBASE, MEDLINE, PsycInfo and the Cochrane Central Register of Controlled Trials, complemented by hand search, up to January 2017. Selection criteria Primary research reporting vaginal pH assessment in pre-labour pregnant women and PTB rate. Data collection and analysis Data extraction and appraisal were carried out in a pre-defined standardised manner, applying the Newcastle-Ottawa scale (NOS) and Cochrane risk of bias tool. Analysis included calculation of risk difference (RD) and narrative synthesis. It was decided to abstain from pooling of the studies due to missing information in important moderators. Main results Of 986 identified records, 30 were included in the systematic review. The risk of bias was considered mostly high (40%) or moderate (37%). Fifteen studies permitted a calculation of RD. Of these, 14 (93%) indicated a positive association between increased antenatal vaginal pH and PTB (RD range: 0.02-0.75). Conclusion An increased antenatal vaginal pH >4.5 may be associated with a higher risk for PTB. It is recommended to conduct a randomised controlled trial (RCT) to investigate the effectiveness of antenatal pH screening to prevent PTB. Tweetable abstract Pregnant women with an increased vaginal pH >4.5 may be at higher risk to experience preterm birth.

A cross-country survey of attitudes toward childbirth technologies and interventions among university students

PROBLEM & AIM

Cultural beliefs that equate birth technology with progress, safety and convenience contribute to widespread acceptance of childbirth technology and interventions. Little is known about attitudes towards childbirth technology and interventions among the next generation of maternity care users and whether attitudes vary by country, age, gender, childbirth fear, and other factors.

METHODS

Data were collected via online survey in eight countries. Students who had never had children, and who planned to have at least one child were eligible to participate.

FINDINGS

The majority of participants (n=4569) were women (79.3%), and the median age was 22 years. More than half of students agreed that birth technology makes birth easier (55.8%), protects babies from harm (49.1%) and that women have a right to choose a medically non-indicated cesarean (50.8%). Respondents who had greater acceptance of childbirth technology and interventions were from countries with higher national caesarean birth rates, reported higher levels of childbirth fear, and were more likely to report that visual media or school-based education shaped their attitudes toward birth. Positive attitudes toward childbirth technology and interventions were also associated with less confidence in knowledge of birth, and more common among younger and male respondents.

DISCUSSION/CONCLUSION

Educational strategies to teach university students about pregnancy and birth in ways that does not frighten them and promotes critical reflection about childbirth technology are needed. This is especially true in countries with high rates of interventions that reciprocally shape culture norms, attitudes, and expectations.

Mode of birth and postnatal health-related quality of life after one previous cesarean in three European countries

BACKGROUND

How a woman gives birth can affect her health-related quality of life (HRQoL). This study explored HRQoL at 3 months postpartum in women with a history of one previous cesarean in three European countries.

METHODS

A prospective longitudinal survey, embedded within a cluster randomized trial in three countries, exploring women's postnatal HRQoL up to 3 months postpartum. The Short-Form Six-Dimensions (SF-6D) was used to measure HRQoL, and multivariate analyses were used to examine the relationship with mode of birth.

RESULTS

Complete data were available from 880 women. Women with a spontaneous vaginal birth had the highest HRQoL scores, whereas women with an emergency repeat cesarean (P = .01) had the lowest. Postnatal readmission of the mother (P = .03), having public health insurance (P = .04), and a low antenatal HRQoL score (P < .01) contributes to poorer HRQoL scores. More specifically, women with a spontaneous vaginal birth had significantly higher HRQoL scores on the vitality dimension compared with women with an emergency repeat cesarean (P = .04).

CONCLUSIONS

In women with low-risk factors, repeat cesareans result in a poorer HRQoL compared with vaginal birth. When there are no contraindications for vaginal birth, women with a history of one previous cesarean should be encouraged to give birth vaginally rather than have an elective repeat cesarean.

Intrapartum Care Working Patterns of Midwives: The Long Road to Models of Care in Germany

INTRODUCTION

Midwifery models of care help to enhance perinatal health outcomes, women's satisfaction, and continuity of care. Despite the ubiquitous presence of certified midwives at births in Germany, no research has investigated the diversity of midwives' practice patterns. Describing the variety of working patterns through which midwives provide intrapartum care may contribute to improving the organisation of midwifery services.

METHODS

This cross-sectional survey took place in the region of Hannover and Hildesheim, Germany. Midwives attending births and practicing in hospitals and/or out-of-hospital were able to participate. Midwives who did not attend births were excluded. We assessed midwives' scope of services, practice locations, employment patterns, continuity of care, midwife-led births, and midwives' level of agreement with core values of midwifery care. The response rate of the survey was 32.7 % (69/211).

RESULTS

We found that midwifery care services can be described according to midwives' employment patterns. The majority of midwives were employed in a hospital to provide intrapartum care (74.2 %, n = 49), and most also independently offered one or more antenatal and/or postpartum service/s. Only 25.8 % (n = 17) of midwives offered their services independently (laborist model of care). Independent midwives attended births in all three possible settings: hospital, free-standing birth centres and home. Significantly more independent midwives than employed midwives offered antenatal care and lactation consulting. Compared to employed midwives, significantly more independent midwives provided antenatal, intrapartum, and postpartum care to the same women, were more likely to know women before labour, and to offer one-to-one care during labour.

DISCUSSION

The most common practice pattern among surveyed midwives was 'employment in a hospital' for provision of intrapartum care with additional postpartum and few antenatal services provided on an independent basis. Midwives who worked solely independently reported more continuity and one-to-one intrapartum care with women. Most midwives did not work in patterns that offered continuity of care or consistently provide one-to-one care. Future research should assess whether women in Germany desire more services similar to caseload midwifery.

Variations in childbirth interventions in high-income countries: protocol for a multinational cross-sectional study

INTRODUCTION

There are growing concerns about the increase in rates of commonly used childbirth interventions. When indicated, childbirth interventions are crucial for preventing maternal and perinatal morbidity and mortality, but their routine use in healthy women and children leads to avoidable maternal and neonatal harm. Establishing ideal rates of interventions can be challenging. This study aims to describe the range of variations in the use of commonly used childbirth interventions in high-income countries around the world, and in outcomes in nulliparous and multiparous women.

METHODS AND ANALYSIS

This multinational cross-sectional study will use data from births in 2013 with national population data or representative samples of the population of pregnant women in high-income countries. Data from women who gave birth to a single child from 37 weeks gestation onwards will be included and the results will be presented for nulliparous and multiparous women separately. Anonymised individual level data will be analysed. Primary outcomes are rates of commonly used childbirth interventions, including induction and/or augmentation of labour, intrapartum antibiotics, epidural and pharmacological pain relief, episiotomy in vaginal births, instrument-assisted birth (vacuum or forceps), caesarean section and use of oxytocin postpartum. Secondary outcomes are maternal and perinatal mortality, Apgar score below 7 at 5 min, postpartum haemorrhage and obstetric anal sphincter injury. Univariable and multivariable logistic regression analyses will be conducted to investigate variations among countries, adjusted for maternal age, body mass index, gestational weight gain, ethnic background, socioeconomic status and infant birth weight. The overall mean rates will be considered as a reference category, weighted for the size of the study population per country.

ETHICS AND DISSEMINATION

The Medical Ethics Review Committee of VU University Medical Center Amsterdam confirmed that an official approval of this study was not required. Results will be disseminated at national and international conferences and published in peer-reviewed journals.

Process evaluation for OptiBIRTH, a randomised controlled trial of a complex intervention designed to increase rates of vaginal birth after caesarean section

Background

Complex interventions encompassing several interconnecting and interacting components can be challenging to evaluate. Examining the underlying trial processes while an intervention is being tested can assist in explaining why an intervention was effective (or not). This paper describes a process evaluation of a pan-European cluster randomised controlled trial, OptiBIRTH (undertaken in Ireland, Italy and Germany), that successfully used both quantitative and qualitative methods to enhance understanding of the underlying trial mechanisms and their effect on the trial outcome.

Methods

We carried out a mixed methods process evaluation. Quantitative and qualitative data were collected from observation of the implementation of the intervention in practice to determine whether it was delivered according to the original protocol. Data were examined to assess the delivery of the various components of the intervention and the receipt of the intervention by key stakeholders (pregnant women, midwives, obstetricians). Using ethnography, an exploration of perceived experiences from a range of recipients was conducted to understand the perspective of both those delivering and those receiving the intervention.

Results

Engagement by stakeholders with the different components of the intervention varied from minimal intensity of women’s engagement with antenatal classes, to moderate intensity of engagement with online resources, to high intensity of clinicians’ exposure to the education sessions provided. The ethnography determined that, although the overall culture in the intervention site did not change, smaller, more individual cultural changes were observed. The fidelity of the delivery of the intervention scored average quality marks of 80% and above on repeat assessments.

Conclusion

Nesting a process evaluation within the trial enabled the observation of the mode of action of the intervention in its practice context and ensured that the intervention was delivered with a good level of consistency. Implementation problems were identified as they arose and were addressed accordingly. When dealing with a complex intervention, collecting and analysing both quantitative and qualitative data, as we did, can greatly enhance the process evaluation.

[Outcomes of Planned Out-of-Hospital and Low-Risk Hospital Births in Lower Saxony]

Introduction Internationally, there is debate on the safety of different birth settings inside and outside of hospitals. Low-risk women in Germany can choose where they give birth, and out-of-hospital births are especially necessary in regions lacking infrastructure. To date, national studies are required. Materials and Methods We investigated planned out-of-hospital (OH) and hospital births in Lower Saxony, Germany, in 2005. Women with a singleton fetus in the vertex position were included once they reached 34+0 gestational weeks. 1 273 out of 4 424 births were included via risk assessment. Outcomes were compared using Pearson's chi-squared test, the Mann-Whitney test, and logistic regression. Results 152 (36.6%) nulliparae (NP) and 263 (63.4%) multiparae (MP) gave birth out of hospital, 439 (51.2%) nulliparae and 419 (48.8%) multiparae in a hospital. 10.1% of women whose care started outside of the hospital needed a transfer to the hospital. Women who planned OH were older and had a higher level of education. Women without a migration background displayed an increased rate of out-of-hospital birth. A higher proportion received their antenatal care from midwives rather than medical doctors. Induction of labor was less likely for women with planned out-of-hospital births, as were other intrapartum interventions. In hospital births, fetal monitoring was more likely performed via cardiotocograph instead of intermittent auscultation. Duration of labor was significantly longer in OH births (median: NP: 9.01 h vs. 7.38 h; MP: 4.53 h vs. 4.25 h). Nulliparae had more spontaneous births out-of-hospital (94.7%) than in hospital (73.6%). There was no difference in adverse fetal outcomes, blood loss, and severe perineal lacerations. The perineum was less frequently intact in hospital births. Retained placenta was more often documented in out-of-hospital births. Conclusions In an out-of-hospital setting, fewer interventions were performed, spontaneous births occurred more often, and there was no difference in neonatal outcomes. OH birth appears reasonably safe with thorough pre-labor risk assessment and good transfer management. Some beneficial aspects of OH birth care (like continuity of care and restriction of routine interventions) could be adopted by hospital labor wards, leading to a higher rate of vaginal births and improved care.

Vaginal birth after caesarean: Views of women from countries with low VBAC rates

PROBLEM AND BACKGROUND

Vaginal birth after caesarean section is a safe option for the majority of women. Seeking women's views can be of help in understanding factors of importance for achieving vaginal birth in countries where the vaginal birth rates after caesarean is low.

AIM

To investigate women's views on important factors to improve the rate of vaginal birth after caesareanin countries where vaginal birth rates after previous caesarean are low.

METHODS

A qualitative study using content analysis. Data were gathered through focus groups and individual interviews with 51 women, in their native languages, in Germany, Ireland and Italy. The women were asked five questions about vaginal birth after caesarean. Data were translated to English, analysed together and finally validated in each country.

FINDINGS

Important factors for the women were that all involved in caring for them were of the same opinion about vaginal birth after caesarean, that they experience shared decision-making with clinicians supportive of vaginal birth, receive correct information, are sufficiently prepared for a vaginal birth, and experience a culture that supports vaginal birth after caesarean.

DISCUSSION AND CONCLUSION

Women's decision-making about vaginal birth after caesarean in these countries involves a complex, multidimensional interplay of medical, psychosocial, cultural, personal and practical considerations. Further research is needed to explore if the information deficit women report negatively affects their ability to make informed choices, and to understand what matters most to women when making decisions about vaginal birth after a previous caesarean as a mode of birth.

Protocol for the development of a salutogenic intrapartum core outcome set (SIPCOS)

BACKGROUND

Maternity intrapartum care research and clinical care more often focus on outcomes that minimise or prevent adverse health rather than on what constitutes positive health and wellbeing (salutogenesis). This was highlighted recently in a systematic review of reviews of intrapartum reported outcomes where only 8% of 1648 individual outcomes, from 102 systematic reviews, were agreed as being salutogenically-focused. Added to this is variation in the outcomes measured in individual studies rendering it very difficult for researchers to synthesise, fully, the evidence from studies on a particular topic. One of the suggested ways to address this is to develop and apply an agreed standardised set of outcomes, known as a 'core outcome set' (COS). In this paper we present a protocol for the development of a salutogenic intrapartum COS (SIPCOS) for use in maternity care research and a SIPCOS for measuring in daily intrapartum clinical care.

METHODS

The study proposes three phases in developing the final SIPCOSs. Phase one, which is complete, involved the conduct of a systematic review of reviews to identify a preliminary list of salutogenically-focused outcomes that had previously been reported in systematic reviews of intrapartum interventions. Sixteen unique salutogenically-focused outcome categories were identified. Phase two will involve prioritising these outcomes, from the perspective of key stakeholders (users of maternity services, clinicians and researchers) by asking them to rate the importance of each outcome for inclusion in the SIPCOSs. A final consensus meeting (phase three) will be held, bringing international stakeholders together to review the preliminary SIPCOSs resulting from the survey and to agree and finalise the final SIPCOSs for use in future maternity care research and daily clinical care.

DISCUSSION

The expectation in developing the SIPCOSs is that they will be collected and reported in all future studies evaluating intrapartum interventions and measured/recorded in future intrapartum clinical care, as routine, alongside other outcomes also deemed important in the context of the study or clinical scenario. Using the SIPCOSs in this way, will promote and encourage standardised measurements of positive health outcomes in maternity care, into the future.

Clinicians' views of factors of importance for improving the rate of VBAC (vaginal birth after caesarean section): a study from countries with low VBAC rates

BACKGROUND

Caesarean section (CS) rates are increasing worldwide and the most common reason is repeat CS following previous CS. For most women a vaginal birth after a previous CS (VBAC) is a safe option. However, the rate of VBAC differs in an international perspective. Obtaining deeper knowledge of clinicians' views on VBAC can help in understanding the factors of importance for increasing VBAC rates. Focus group interviews with clinicians and women in three countries with high VBAC rates (Finland, Sweden and the Netherlands) and three countries with low VBAC rates (Ireland, Italy and Germany) are part of "OptiBIRTH", an ongoing research project. The study reported here aims to explore the views of clinicians from countries with low VBAC rates on factors of importance for improving VBAC rates.

METHODS

Focus group interviews were held in Ireland, Italy and Germany. In total 71 clinicians participated in nine focus group interviews. Five central questions about VBAC were used and interviews were analysed using content analysis. The analysis was performed in each country in the native language and then translated into English. All data were then analysed together and final categories were validated in each country.

RESULTS

The findings are presented in four main categories with several sub-categories: 1) "prameters for VBAC", including the importance of the obstetric history, present obstetric factors, a positive attitude among those who are centrally involved, early follow-up after CS and antenatal classes; 2) "organisational support and resources for women undergoing a VBAC", meaning a successful VBAC requires clinical expertise and resources during labour; 3) "fear as a key inhibitor of successful VBAC", including understanding women's fear of childbirth, clinicians' fear of VBAC and the ways that clinicians' fear can be transferred to women; and 4) "shared decision making - rapport, knowledge and confidence", meaning ensuring consistent, realistic and unbiased information and developing trust within the clinician-woman relationship.

CONCLUSIONS

The findings indicate that increasing the VBAC rate depends on organisational factors, the care offered during pregnancy and childbirth, the decision-making process and the strategies employed to reduce fear in all involved.

Accelerated Training of Skilled Birth Attendants in a Marginalized Population on the Thai-Myanmar Border: A Multiple Methods Program Evaluation

Background

To evaluate a skilled birth attendant (SBA) training program in a neglected population on the Thai-Myanmar border, we used multiple methods to show that refugee and migrant health workers can be given effective training in their own environment to become SBAs and teachers of SBAs. The loss of SBAs through resettlement to third countries necessitated urgent training of available workers to meet local needs.

Methods and Findings

All results were obtained from student records of theory grades and clinical log books. Qualitative evaluation of both the SBA and teacher programs was obtained using semi-structured interviews with supervisors and teachers. We also reviewed perinatal indicators over an eight-year period, starting prior to the first training program until after the graduation of the fourth cohort of SBAs.

Results

Four SBA training programs scheduled between 2009 and 2015 resulted in 79/88 (90%) of students successfully completing a training program of 250 theory hours and 625 supervised clinical hours. All 79 students were able to: achieve pass grades on theory examination (median 80%, range [70–89]); obtain the required clinical experience within twelve months; achieve clinical competence to provide safe care during childbirth. In 2010–2011, five experienced SBAs completed a train-the-trainer (TOT) program and went on to facilitate further training programs. Perinatal indicators within Shoklo Malaria Research Unit (SMRU), such as place of birth, maternal and newborn outcomes, showed no significant differences before and after introduction of training or following graduate deployment in the local maternity units. Confidence, competence and teamwork emerged from qualitative evaluation by senior SBAs working with and supervising students in the clinics.

Conclusions

We demonstrate that in resource-limited settings or in marginalized populations, it is possible to accelerate training of skilled birth attendants to provide safe maternity care. Education needs to be tailored to local needs to ensure evidence-based care of women and their families.

Early versus Late Admission to Labor Affects Labor Progression and Risk of Cesarean Section in Nulliparous Women

Background

Rates of cesarean section increase worldwide, and the components of this increase are partially unknown. A strong role is prescribed to dystocia, and at the same time, the diagnosis of dystocia is highly subjective. Previous studies indicated that risk of cesarean is higher when women are admitted to the hospital early in the labor.

Methods

We examined data on 1,202 nulliparous women with singleton, vertex pregnancies and spontaneous labor onset. We selected three groups based on cervical dilatation at admission: early (0.5–1.5 cm, N = 178), intermediate (2.5–3.5 cm, N = 320), and late (4.5–5.5 cm, N = 175). The Kaplan–Meier estimator was used to analyze the risk of delivery by cesarean section at a given dilatation, and thin-plate spline regression with a binary outcome (R library gam) to assess the form of the associations between the cesarean section in either the first or second stage versus vaginal delivery and dilatation at admission.

Results

Women who were admitted to labor early had a higher risk of delivery by cesarean section (18 versus 4% in the late admission group), while the risk of instrumental delivery did not differ (24 versus 24%). Before 4 cm dilatation, the earlier a woman was admitted to labor, the higher was her risk of delivery by cesarean section. After 4 cm dilatation, however, the relationship disappeared. These patterns were true for both first and second stage cesarean deliveries. Oxytocin use was associated with a higher risk of cesarean section only in the middle group (2.5–3.5 cm dilatation at admission).

Conclusion

Early admission to labor was associated with a significantly higher risk of delivery by cesarean section during the first and second stages. Differential effects of oxytocin augmentation depending on dilation at admission may suggest that admission at the early stage of labor is an indicator rather than a risk factor itself, but admission at the intermediate stage (2.5–3.5 cm) becomes a risk factor itself. Further research is needed to study this hypothesis.

Diagnosing onset of labor: a systematic review of definitions in the research literature

BACKGROUND

The diagnosis of labor onset has been described as one of the most important judgments in maternity care. There is compelling evidence that the duration of both latent and active phase labor are clinically important and require consistent approaches to measurement. In order to measure the duration of labor phases systematically, we need standard definitions of their onset. We reviewed the literature to examine definitions of labor onset and the evidentiary basis provided for these definitions.

METHODS

Five electronic databases were searched using predefined search terms. We included English, French and German language studies published between January 1978 and March 2014 defining the onset of latent labor and/or active labor in a population of healthy women with term births. Studies focusing exclusively on induced labor were excluded.

RESULTS

We included 62 studies. Four 'types' of labor onset were defined: latent phase, active phase, first stage and unspecified. Labor onset was most commonly defined through the presence of regular painful contractions (71% of studies) and/or some measure of cervical dilatation (68% of studies). However, there was considerable discrepancy about what constituted onset of labor even within 'type' of labor onset. The majority of studies did not provide evidentiary support for their choice of definition of labor onset.

CONCLUSIONS

There is little consensus regarding definitions of labor onset in the research literature. In order to avoid misdiagnosis of the onset of labor and identify departures from normal labor trajectories, a consistent and measurable definition of labor onset for each phase and stage is essential. In choosing standard definitions, the consequences of their use on rates of maternal and fetal morbidity must also be examined.

Stillbirths: recall to action in high-income countries

Variation in stillbirth rates across high-income countries and large equity gaps within high-income countries persist. If all high-income countries achieved stillbirth rates equal to the best performing countries, 19,439 late gestation (28 weeks or more) stillbirths could have been avoided in 2015. The proportion of unexplained stillbirths is high and can be addressed through improvements in data collection, investigation, and classification, and with a better understanding of causal pathways. Substandard care contributes to 20-30% of all stillbirths and the contribution is even higher for late gestation intrapartum stillbirths. National perinatal mortality audit programmes need to be implemented in all high-income countries. The need to reduce stigma and fatalism related to stillbirth and to improve bereavement care are also clear, persisting priorities for action. In high-income countries, a woman living under adverse socioeconomic circumstances has twice the risk of having a stillborn child when compared to her more advantaged counterparts. Programmes at community and country level need to improve health in disadvantaged families to address these inequities.

Women's perceptions of induction of labour outcomes: Results of an online-survey in Germany

OBJECTIVE

induction of labour (IOL) is a common procedure in high income countries. It may be conducted for medical as well as non-medical reasons. Women's views on induction of labour have not extensively been evaluated as yet. Also, women's preferences for certain methods of induction including alternative and complementary methods need further exploration in order to meet their expectations and needs.

DESIGN AND SETTING

we published a short online questionnaire on women'views and experiences with IOL.

MEASUREMENTS AND FINDINGS

we asked for indication and gestational age at induction; method of induction, duration of labour and mode of birth. We also asked for the extent of desired, and experienced support and participation in decision-making. Within four weeks of being online, 698 women answered the questionnaire. Most frequent reasons for induction were postmaturity (51.7%), doctor's recommendation (31.6%) and medical complications (25.6%). Most women were induced with misoprostol or dinoprostone, but nearly half of the respondents were also offered, or asked for, complementary and alternative methods (CAM). 50% or more women would have preferred more information on alternatives to IOL, methods of IOL, side effects of the drugs, information on alternatives (59.2%) and on the medication (55.3%). Many would have wished for more support (49.9%) with decision-making (55.2%), and more time (54.1%).

KEY CONCLUSION

women' expectations and needs regarding IOL are widely unmet in current clinical practice.

IMPLICATIONS FOR PRACTICE

there is a need for evidence-based information and decisional support for pregnant women who need to decide how to proceed once term is reached.

Improving the organisation of maternal health service delivery and optimising childbirth by increasing vaginal birth after caesarean section through enhanced women-centred care (OptiBIRTH trial): study protocol for a randomised controlled trial (ISRCTN10612254)

BACKGROUND

The proportion of pregnant women who have a caesarean section shows a wide variation across Europe, and concern exists that these proportions are increasing. Much of the increase in caesarean sections in recent years is due to a cascade effect in which a woman who has had one caesarean section is much more likely to have one again if she has another baby. In some places, it has become common practice for a woman who has had a caesarean section to have this procedure again as a matter of routine. The alternative, vaginal birth after caesarean (VBAC), which has been widely recommended, results in fewer undesired results or complications and is the preferred option for most women. However, VBAC rates in some countries are much lower than in other countries.

METHODS/DESIGN

The OptiBIRTH trial uses a cluster randomised design to test a specially developed approach to try to improve the VBAC rate. It will attempt to increase VBAC rates from 25 % to 40 % through increased women-centred care and women's involvement in their care. Sixteen hospitals in Germany, Ireland and Italy agreed to join the study, and each hospital was randomly allocated to be either an intervention or a control site.

DISCUSSION

If the OptiBIRTH intervention succeeds in increasing VBAC rates, its application across Europe might avoid the 160,000 unnecessary caesarean sections that occur every year at an extra direct annual cost of more than €150 million.
