Mode of birth and medical interventions among women at low risk of complications: A cross-national comparison of birth settings in England and the Netherlands

Choosing for a Homebirth during COVID-19 Lockdown in The Netherlands, who and why: A national prospective questionnaire study

OBJECTIVE

During the first COVID-19 lockdown in the Netherlands (9 March-1 June 2020), the homebirth rate increased from 27 % to 37 % among women with low-risk pregnancies starting labour in primary midwife-led care (overall population: 15 % in 2020). We explored characteristics and motivations of women who change their preference from a hospital birth to a home birth.

DESIGN

A nationwide prospective online questionnaire.

SETTING

Questionnaires were distributed during the first COVID-19 wave (4 April-11 May 2020), as well as at follow-up (infant ±6 months old).

POPULATION

Women who were pregnant during the first COVID-19 wave (N = 778), who either changed their preferred birth location from a hospital to a home birth or who maintained their original preference.

METHODS AND MAIN OUTCOME MEASURES

We compared characteristics, anticipatory worries, and mental health between these groups, using descriptive statistics.

RESULTS

The most frequently reported change in preferred birth location among included women was from a hospital to a homebirth (15 %). This was primarily experienced as a choice rather than out of necessity (84 %). Women preferring homebirths had fewer risk factors (-11 %, 95 % CI: -5 % to -16 %) and had higher COVID-19 related worry scores (+0.09, 95 % CI: 0.01 to 0.18; for scale: IQR 0.45-1.09) compared to women who maintained their original preference. Main concerns were the absence of the support of friends or family during or after birth, and exposure to COVID-19.

CONCLUSION

During the first COVID-19 lockdown in the Netherlands, women changing their preferred location of birth to a homebirth had fewer risk factors and more COVID-19 related worries pertaining to a hospital birth.

Associations between different types of delivery, empathy, aggression, impulsivity and school bullying in children attending public and private schools in Pereira (Colombia)

This study aimed to correlate exposure to oxytocin during childbirth with behavioral determinants in teenage students. The Barratt Questionnaire (BQ), the Buss and Perry Aggression Questionnaire (BPAQ) and the Bryant Empathy Index (BEI), respectively measured impulsivity, aggression and empathy; the results were correlated with the roles of school bullying through the Velásquez and Pineda scale. Mothers were asked about birth circumstances. A total of 401 students were included (mean age 12 ± 1 years, 53,9 % were male, 53,3 % were attending a public school). 41,9 % of students had exogenous oxytocin exposure, 40,1 % had physiological oxytocin exposure, and 18 % had no oxytocin exposure. Regarding bullying, 75,1 % of students were classified as observers, 14,2 % were classified as victims, 6 % were classified as intimidators and 4,7 % exhibited an indifferent role. The mean value of the BPAQ was 78 ± 19, for the BEI was 78 ± 10 and for the BQ was 60 ± 10; all values were considered high. There were no significant differences among the type of delivery, sex and bullying roles or the type of delivery, aggressiveness and impulsivity according to sex; however, males had significantly lower empathy scores. There was no significant association between the type of delivery and the risk of assuming a bullying role. A regression model showed a significant association between attending a private school and a lower risk of developing a victim or intimidator role. This study could contribute to a better understanding of the processes involved in behavioral and emotional outcomes after birth, which can help to design prevention strategies to address increasing mental health problems in youth. Furthermore, this study could help emphasize the importance of promoting physiological delivery and find evidence that helps the scientific community design new work to deepen the relationship between oxytocin and behavior.

Effect of COVID-19 lockdown on maternity care and maternal outcome in the Netherlands: a national quasi-experimental study

OBJECTIVES

The COVID-19 pandemic and associated lockdowns disrupted health care worldwide. High-income countries observed a decrease in preterm births during lockdowns, but maternal pregnancy-related outcomes were also likely affected. This study investigates the effect of the first COVID-19 lockdown (March-June 2020) on provision of maternity care and maternal pregnancy-related outcomes in the Netherlands.

STUDY DESIGN

National quasi-experimental study.

METHODS

Multiple linked national registries were used, and all births from a gestational age of 24+0 weeks in 2010-2020 were included. In births starting in midwife-led primary care, we assessed the effect of lockdown on provision of care. In the general pregnant population, the impact on characteristics of labour and maternal morbidity was assessed. A difference-in-regression-discontinuity design was used to derive causal estimates for the year 2020.

RESULTS

A total of 1,039,728 births were included. During the lockdown, births to women who started labour in midwife-led primary care (49%) more often ended at home (27% pre-lockdown, +10% [95% confidence interval: +7%, +13%]). A small decrease was seen in referrals towards obstetrician-led care during labour (46%, -3% [-5%,-0%]). In the overall group, no significant change was seen in induction of labour (27%, +1% [-1%, +3%]). We found no significant changes in the incidence of emergency caesarean section (9%, -1% [-2%, +0%]), obstetric anal sphincter injury (2%, +0% [-0%, +1%]), episiotomy (21%, -0% [-2%, +1%]), or post-partum haemorrhage: >1000 ml (6%, -0% [-1%, +1%]).

CONCLUSIONS

During the first COVID-19 lockdown in the Netherlands, a substantial increase in homebirths was seen. There was no evidence for changed available maternal outcomes, suggesting that a maternity care system with a strong midwife-led primary care system may flexibly and safely adapt to external disruptions.

Midwife-attended planned home births versus planned hospital births in Spain: Maternal and neonatal outcomes

BACKGROUND

The debate on the safety and outcomes of home versus hospital births highlights the need for evidence-based evaluations of these birthing settings, particularly in Catalonia where both options are available.

AIM

To compare sociodemographic characteristics and maternal and neonatal outcomes between low-risk women opting for home versus hospital births in Catalonia, Spain.

METHODS

This observational cross-sectional study analysed 3,463 low-risk births between 2016 and 2018, including 2,713 hospital and 750 home births. Researchers collected sociodemographic data, birthing processes, and outcomes, using statistical analysis to explore differences between the settings.

FINDINGS

Notable differences emerged: Women choosing home births typically had higher education levels and were predominantly Spanish. They were 3.43 times more likely to have a spontaneous birth and significantly less likely to undergo instrumental births than those in hospitals. Home births were associated with higher utilization of non-pharmacological analgesia and a more pronounced tendency to iniciate breastfeeding within the first hour post birth and stronger inclination towards breastfeeding. Hospital births, conversely, showed higher use of the lithotomy position and epidural analgesia. There were no significant differences in neonatal outcomes between the two groups.

CONCLUSIONS AND IMPLICATION FOR PRACTICE

Home births managed by midwives offered better obstetric and neonatal outcomes for low-risk women than hospital births. These results suggest home birth as a safe, viable option that promotes natural birthing processes and reduces medical interventions. The study supports the integration of midwife-led home birth into public health policies, affirming its benefits for maternal and neonatal health.

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.

The first alongside midwifery unit in Spain: A retrospective cohort study of maternal and neonatal outcomes

BACKGROUND

Midwife-led units have been shown to be safer and reduce interventions for women at low risk of complications at birth. In 2017, the first alongside birth center was opened in Spain. The aim of this study was to compare outcomes for women with uncomplicated pregnancies giving birth in the Midwife-led unit (MLU) and in the Obstetric unit (OU) of the same hospital.

METHODS

Retrospective cohort study comparing birth outcomes between low-risk women, depending on their planned place of birth. Data were analyzed with an intention-to-treat approach for women that gave birth between January 2018 and December 2020.

RESULTS

A total of 878 women were included in the study, 255 women chose to give birth in the MLU and 623 in the OU. Findings showed that women in the MLU were more likely to have a vaginal birth (91.4%) than in the OU (83.8%) (aOR 2.98 [95%CI 1.62-5.47]), less likely to have an instrumental delivery, 3.9% versus 11.2% (0.25 [0.11-0.55]), to use epidural analgesia, 19.6% versus 77.9% (0.15 [0.04-0.17]) and to have an episiotomy, 7.4% versus 15.4% (0.27 [0.14-0.53]). There were no differences in rates of postpartum hemorrhage, retained placenta, or adverse neonatal outcomes. Intrapartum and postpartum transfer rates from the MLU to the OU were 21.1% and 2.4%, respectively.

CONCLUSIONS

The high rate of obstetric interventions in Spain could be reduced by implementing midwife-led units across the whole system, without an increase in maternal or neonatal complications.

Peripartum severe acute maternal morbidity in low-risk women: A population-based study

BACKGROUND

Knowledge of severe acute maternal morbidity (SAMM) and its risk factors is constantly growing, but studies have rarely focused on the specific population of low-risk women.

AIM

To estimate the prevalence and to identify subgroups at risk of peripartum SAMM in low-risk women METHODS: From a population-based cohort-nested case-control study conducted in six French regions, i.e., 182 309 women who gave birth at ≥22 weeks in 119 maternity units, we selected women considered at low risk up to the end of pregnancy before labour according to the NICE guidelines and compared those experiencing peripartum SAMM (during birth and up to 7 days postpartum; n = 489) to a 2% random sample of women without peripartum SAMM from the same units (n = 1800). Risk factors for peripartum SAMM were identified by multivariable logistic regression.

FINDINGS

amongst low-risk women, the estimated rate of SAMM was 0.548/100 deliveries (95%CI 0.501-0.599). Severe obstetric haemorrhage was the main cause (83.6% of SAMM cases). Main risk factors for peripartum SAMM were primiparity (aOR 2.4, 95%CI 1.9-3.0), IVF pregnancy (aOR 1.8, 1.0-3.4), third-trimester anaemia (aOR 1.7, 1.3-2.3), being born out of Europe or Africa (aOR 1.9, 1.2-3.0).

CONCLUSION

amongst women considered at low risk up to the end of pregnancy before labour, peripartum SAMM is rare but still exists. Knowledge of risk factors of SAMM in this population will inform the discussion on peripartum risks and the most appropriate place of birth for each woman.

Women's views and experiences of augmentation of labour with synthetic oxytocin infusion: A qualitative evidence synthesis

OBJECTIVE

To explore and synthesise women's views and experiences of augmentation of labour with synthetic oxytocin infusion.

DESIGN

A qualitative evidence synthesis was conducted. The SPIDER acronym was used to develop the search terms and determine the inclusion criteria. Six bibliographic databases: MEDLINE, CINAHL, EMBASE, PsycINFO, Maternity and Infant Care and Web of Science Core Collection were searched in October 2021. Grey literature sources, EThOS, DART-Europe, and the World Health Organization's Clinical Trials Registry were searched, and reference lists of included studies were reviewed. Methodological quality of included studies was assessed using the Evidence for Policy and Practice Information and Co-ordinating (EPPI) Centre assessment tool. Data were synthesised thematically. The confidence of each review finding was assessed using the Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual). Research ethical approval was not required.

SETTING AND PARTICIPANTS

Women of any age, parity, and cultural background who underwent augmentation of labour with synthetic oxytocin infusion were included.

FINDINGS

A total of 9306 citations were retrieved. Twenty-five studies conducted across 14 countries met the inclusion criteria and contributed data. Three principal analytical themes emerged: feeling stuck; past and present shaping the future; and cause and effect of augmentation of labour. The decision to augment women's labour was often performed without their informed consent. Women's views and experiences of augmentation of labour were shaped according to their knowledge, beliefs and support received during labour. Irrespective of the context, women consistently associated augmentation of labour with pain.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Clinical guidelines on augmentation of labour need to be informed by research that includes women's views and experiences as a main outcome. Future research exploring the experience of augmentation of labour rather than the experience of labour dystocia would be beneficial. Increasing women's awareness and knowledge of augmentation of labour may help to ensure that their informed consent is obtained. Healthcare providers should discuss the effects, side effects and implications of augmentation of labour with women, ideally before labour.

The natural pattern of birth timing and gestational age in the U.S. compared to England, and the Netherlands

OBJECTIVE

To examine cross-national differences in gestational age over time in the U.S. and across three wealthy countries in 2020 as well as examine patterns of birth timing by hour of the day in home and spontaneous vaginal hospital births in the three countries.

METHODS

We did a comparative cohort analysis with data on gestational age and the timing of birth from the United States, England and the Netherlands, comparing hospital and home births. For overall gestational age comparisons, we drew on national birth cohorts from the U.S. (1990, 2014 & 2020), the Netherlands (2014 & 2020) and England (2020). Birth timing data was drawn from national data from the U.S. (2014 & 2020), the Netherlands (2014) and from a large representative sample from England (2008-10). We compared timing of births by hour of the day in hospital and home births in all three countries.

RESULTS

The U.S. overall mean gestational age distribution, based on last menstrual period, decreased by more than half a week between 1990 (39.1 weeks) and 2020 (38.5 weeks). The 2020 U.S. gestational age distribution (76% births prior to 40 weeks) was distinct from England (60%) and the Netherlands (56%). The gestational age distribution and timing of home births was comparable in the three countries. Home births peaked in early morning between 2:00 am and 5:00 am. In England and the Netherlands, hospital spontaneous vaginal births showed a generally similar timing pattern to home births. In the U.S., the pattern was reversed with a prolonged peak of spontaneous vaginal hospital births between 8:00 am to 5:00 pm.

CONCLUSIONS

The findings suggest organizational priorities can potentially disturb natural patterns of gestation and birth timing with a potential to improve U.S. perinatal outcomes with organizational models that more closely resemble those of England and the Netherlands.

Pregnant women's willingness to participate in a randomized trial comparing induction of labor at 39 weeks versus expectant management: A survey in the Netherlands

INTRODUCTION

A randomized controlled trial (RCT) in the United States, the ARRIVE trial, has indicated that induction of labor (IOL) in low-risk nulliparous women with a gestational age (GA) of 39 weeks compared to expectant management (EM) resulted in a significant lower rate of cesarean deliveries. The Dutch maternity care system is different compared to the United States with, among other factors, an overall significantly lower percentage of caesarean sections (CS). To investigate whether IOL has a favorable outcome in the Dutch maternity care system, a new trial is advised. In this questionnaire-based study we aim to evaluate whether Dutch low-risk pregnant women would be willing to participate in an RCT comparing IOL at 39 weeks to EM.

MATERIALS AND METHODS

We conducted an online survey in 2020 in the Netherlands. Respondent recruitment took place both in outpatient clinics at hospitals and midwife practices and via social media. Inclusion criteria were pregnant women with singleton gestation, GA ≤ 39 weeks, age 18 years or older and residency in the Netherlands. Exclusion criteria were multiple gestation, a history of a CS, planned IOL or CS in current pregnancy and GA > 39 weeks. A subgroup was formed of low risk (receiving primary care) nulliparous women with a gestational age between 34 and 39 weeks, comparable with the ARRIVE trial.

RESULTS

Three hundred eighty respondents participated. Of all respondents (nulli- and multiparous), 47 (12.4%) would be willing to participate in the hypothetical RCT and 70 (18.4%) might be willing to participate. Amongst the 70 women in the subgroup 11 women (15.7%) would be willing to participate and 17 (24.3%) might be willing to participate.

DISCUSSION AND CONCLUSION

Calculating sample size in a country with a low CS rate, in relation to 69.2% of women are not willing to participate in an RCT comparing IOL at 39 weeks with EM, would require >18.000 women to be counselled for participation. We believe such a study is a challenge in the Netherlands.

Experiences of Dutch maternity care professionals during the first wave of COVID-19 in a community based maternity care system

Background and objective

During the COVID-19 pandemic the organization of maternity care changed drastically; this study into the experiences of maternity care professionals with these changes provides suggestions for the organization of care during and after pandemics.

Design

An online survey among Dutch midwives, obstetricians and obstetric residents. Multinomial logistic regression analyses were used to investigate associations between the respondents’ characteristics and answers.

Results

Reported advantages of the changes were fewer prenatal and postpartum consultations (50.1%). The necessity and safety of medical interventions and ultrasounds were considered more critically (75.9%); 14.8% of community midwives stated they referred fewer women to the hospital for decreased fetal movements, whereas 64.2% of the respondents working in hospital-based care experienced fewer consultations for this indication. Respondents felt that women had more confidence in giving birth at home (57.5%). Homebirths seemed to have increased according to 38.5% of the community midwives and 65.3% of the respondents working in hospital-based care. Respondents appreciated the shift to more digital consultations rather than face-to-face consultations. Mentioned disadvantages were that women had appointments alone, (71.1%) and that the community midwife was not allowed to join a woman to obstetric-led care during labour and subsequently stay with her (56.8%). Fewer postpartum visits by family and friends led to more tranquility (59.8%). Overall, however, 48.0% of the respondents felt that the safety of maternity care was compromised due to policy changes.

Conclusions

Maternity care professionals were positive about the decrease in routine care and the increased confidence of women in home birth, but also felt that safety in maternity care was sometimes compromised. According to the respondents in a future crisis situation it should be possible for community midwives to continue to deliver a personal handover after the referral of women to the hospital, and to stay with them.

Caesarean sections and health financing: a global analysis

OBJECTIVES

The objective of this study is to explore the association of health financing indicators with the proportion of births by caesarean section (CS) across countries.

DESIGN

Ecological cross-country study.

SETTING

This study examines CS proportions across 172 countries.

MAIN OUTCOME MEASURES

The primary outcome was the percentage excess of CS proportion, defined as CS proportions above the global target of 19%. We also analysed continuous CS proportions, as well as excess proportion with a more restrictive 9% global target. Multivariable linear regressions were performed to test the association of health financing factors with the percentage excess proportions of CS. The health financing factors considered were total available health system resources (as percentage of gross domestic product), total contributions from private households (out-of-pocket, compulsory and voluntary health insurance contributions) and total national income.

RESULTS

We estimate that in 2018 there were a total of 8.8 million unnecessary CS globally, roughly two-thirds of which occurred in upper middle-income countries. Private health financing was positively associated with percentage excess CS proportion. In models adjusted for income and total health resources as well as human resources, each 10 per cent increase in out-of-pocket expenditure was associated with a 0.7 per cent increase in excess CS proportions. A 10 per cent increase in voluntary health insurance was associated with a 4 per cent increase in excess CS proportions.

CONCLUSIONS

We have found that health system finance features are associated with CS use across countries. Further monitoring of these indicators, within countries and between countries will be needed to understand the effect of financial arrangements in the provision of CS.

Intrapartum synthetic oxytocin, behavioral and emotional problems in children, and the role of postnatal depressive symptoms, postnatal anxiety and mother-to-infant bonding: A Dutch prospective cohort study

OBJECTIVE

To examine the association between intrapartum synthetic oxytocin and child behavioral and emotional problems and to assess if maternal depressive or anxious symptoms or mother-to-infant bonding play a mediating role in this association.

DESIGN

Prospective cohort study.

SETTING

Population-based Pregnancy Anxiety and Depression Study.

PARTICIPANTS

Pregnant women in their first trimester of pregnancy visiting a total of 109 primary and nine secondary obstetric care centers in the Netherlands between 2010 and 2014 were invited to participate. Follow-up measures used for the present study were collected from May 2010 to January 2019. Women with multiple gestations and with a preterm birth were excluded.

MEASUREMENTS

Intrapartum synthetic oxytocin exposure status was based on medical birth records and was defined as its administration (Yes/No), either for labour induction or augmentation. Child behavioral and emotional problems were measured with the Child Behavior Checklist at up to 60 months postpartum. Maternal depressive symptoms, anxiety and mother-to infant bonding were measured with the Edinburgh Postnatal Depression Scale, State Trait Anxiety Inventory and the Mother-to-Infant Bonding Scale from 6 months postpartum. We used multivariable linear regression models to estimate standardized beta coefficients and unique variance explained.

FINDINGS

1,528 women responded. In total 607 women received intrapartum synthetic oxytocin. Intrapartum synthetic oxytocin administration was not associated with child behavioral and emotional problems, mother-to-infant bonding nor with postnatal anxiety. Intrapartum synthetic oxytocin was however significantly but weakly associated with more postnatal depressive symptoms (β=0.17, 95%CI of 0.03 to 0.30) explaining 0.6% of unique variance. Maternal postnatal depressive symptoms, postnatal anxiety symptoms and suboptimal mother-to-infant bonding were positively associated with child behavioral and emotional problems.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

We found no evidence that intrapartum synthetic oxytocin is associated with child behavioral and emotional problems, mother-to-infant bonding, or with postnatal anxiety symptoms. Because there was no association between intrapartum synthetic oxytocin and behavioral and emotional problems in children no mediation analysis was carried out. However, intrapartum synthetic oxytocin was positively but weakly associated with postnatal depressive symptoms. The clinical relevance of this finding is negligible in the general population, but unknown in a population with a high risk of depression.

The role of midwifery and other international insights for maternity care in the United States: An analysis of four countries

BACKGROUND

The United States (US) spends more on health care than any other high-resource country. Despite this, their maternal and newborn outcomes are worse than all other countries with similar levels of economic development. Our purpose was to describe maternal and newborn outcomes and organization of care in four high-resource countries (Australia, Canada, the Netherlands, and United Kingdom) with consistently better outcomes and lower health care costs, and to identify opportunities for emulation and improvement in the United States.

METHOD

We examined resources that described health care organization and financing, provider types, birth settings, national, clinical guidelines, health care policies, surveillance data, and information for consumers. We conducted interviews with country stakeholders representing the disciplines of obstetrics, midwifery, pediatrics, neonatology, epidemiology, sociology, political science, public health, and health services. The results of the analysis were compared and contrasted with the US maternity system.

RESULTS

The four countries had lower rates of maternal mortality, low birthweight, and newborn and infant death than the United States. Five commonalities were identified as follows: (1) affordable/ accessible health care, (2) a maternity workforce that emphasized midwifery care and interprofessional collaboration, (3) respectful care and maternal autonomy, (4) evidence-based guidelines on place of birth, and (5) national data collections systems.

CONCLUSIONS

The findings reveal marked differences in the other countries compared to the United States. It is critical to consider the evidence for improved maternal and newborn outcomes with different models of care and to examine US cultural and structural failures that are leading to unacceptable and substandard maternal and infant outcomes.

Induction of labour at 41 weeks or expectant management until 42 weeks: A systematic review and an individual participant data meta-analysis of randomised trials

BACKGROUND

The risk of perinatal death and severe neonatal morbidity increases gradually after 41 weeks of pregnancy. Several randomised controlled trials (RCTs) have assessed if induction of labour (IOL) in uncomplicated pregnancies at 41 weeks will improve perinatal outcomes. We performed an individual participant data meta-analysis (IPD-MA) on this subject.

METHODS AND FINDINGS

We searched PubMed, Excerpta Medica dataBASE (Embase), The Cochrane Library, Cumulative Index of Nursing and Allied Health Literature (CINAHL), and PsycINFO on February 21, 2020 for RCTs comparing IOL at 41 weeks with expectant management until 42 weeks in women with uncomplicated pregnancies. Individual participant data (IPD) were sought from eligible RCTs. Primary outcome was a composite of severe adverse perinatal outcomes: mortality and severe neonatal morbidity. Additional outcomes included neonatal admission, mode of delivery, perineal lacerations, and postpartum haemorrhage. Prespecified subgroup analyses were conducted for parity (nulliparous/multiparous), maternal age (<35/≥35 years), and body mass index (BMI) (<30/≥30). Aggregate data meta-analysis (MA) was performed to include data from RCTs for which IPD was not available. From 89 full-text articles, we identified three eligible RCTs (n = 5,161), and two contributed with IPD (n = 4,561). Baseline characteristics were similar between the groups regarding age, parity, BMI, and higher level of education. IOL resulted overall in a decrease of severe adverse perinatal outcome (0.4% [10/2,281] versus 1.0% [23/2,280]; relative risk [RR] 0.43 [95% confidence interval [CI] 0.21 to 0.91], p-value 0.027, risk difference [RD] -57/10,000 [95% CI -106/10,000 to -8/10,000], I2 0%). The number needed to treat (NNT) was 175 (95% CI 94 to 1,267). Perinatal deaths occurred in one (<0.1%) versus eight (0.4%) pregnancies (Peto odds ratio [OR] 0.21 [95% CI 0.06 to 0.78], p-value 0.019, RD -31/10,000, [95% CI -56/10,000 to -5/10,000], I2 0%, NNT 326, [95% CI 177 to 2,014]) and admission to a neonatal care unit ≥4 days occurred in 1.1% (24/2,280) versus 1.9% (46/2,273), (RR 0.52 [95% CI 0.32 to 0.85], p-value 0.009, RD -97/10,000 [95% CI -169/10,000 to -26/10,000], I2 0%, NNT 103 [95% CI 59 to 385]). There was no difference in the rate of cesarean delivery (10.5% versus 10.7%; RR 0.98, [95% CI 0.83 to 1.16], p-value 0.81) nor in other important perinatal, delivery, and maternal outcomes. MA on aggregate data showed similar results. Prespecified subgroup analyses for the primary outcome showed a significant difference in the treatment effect (p = 0.01 for interaction) for parity, but not for maternal age or BMI. The risk of severe adverse perinatal outcome was decreased for nulliparous women in the IOL group (0.3% [4/1,219] versus 1.6% [20/1,264]; RR 0.20 [95% CI 0.07 to 0.60], p-value 0.004, RD -127/10,000, [95% CI -204/10,000 to -50/10,000], I2 0%, NNT 79 [95% CI 49 to 201]) but not for multiparous women (0.6% [6/1,219] versus 0.3% [3/1,264]; RR 1.59 [95% CI 0.15 to 17.30], p-value 0.35, RD 27/10,000, [95% CI -29/10,000 to 84/10,000], I2 55%). A limitation of this IPD-MA was the risk of overestimation of the effect on perinatal mortality due to early stopping of the largest included trial for safety reasons after the advice of the Data and Safety Monitoring Board. Furthermore, only two RCTs were eligible for the IPD-MA; thus, the possibility to assess severe adverse neonatal outcomes with few events was limited.

CONCLUSIONS

In this study, we found that, overall, IOL at 41 weeks improved perinatal outcome compared with expectant management until 42 weeks without increasing the cesarean delivery rate. This benefit is shown only in nulliparous women, whereas for multiparous women, the incidence of mortality and morbidity was too low to demonstrate any effect. The magnitude of risk reduction of perinatal mortality remains uncertain. Women with pregnancies approaching 41 weeks should be informed on the risk differences according to parity so that they are able to make an informed choice for IOL at 41 weeks or expectant management until 42 weeks.

Risk of complicated birth at term in nulliparous and multiparous women using routinely collected maternity data in England: cohort study

OBJECTIVES

To determine the rate of complicated birth at term in women classified at low risk according to the National Institute for Health and Care Excellence guideline for intrapartum care (no pre-existing medical conditions, important obstetric history, or complications during pregnancy) and to assess if the risk classification can be improved by considering parity and the number of risk factors.

DESIGN

Cohort study using linked electronic maternity records.

PARTICIPANTS

276 766 women with a singleton birth at term after a trial of labour in 87 NHS hospital trusts in England between April 2015 and March 2016.

MAIN OUTCOME MEASURE

A composite outcome of complicated birth, defined as a birth with use of an instrument, caesarean delivery, anal sphincter injury, postpartum haemorrhage, or Apgar score of 7 or less at five minutes.

RESULTS

Multiparous women without a history of caesarean section had the lowest rates of complicated birth, varying from 8.8% (4879 of 55 426 women, 95% confidence interval 8.6% to 9.0%) in those without specific risk factors to 21.8% (613 of 2811 women, 20.2% to 23.4%) in those with three or more. The rate of complicated birth was higher in nulliparous women, with corresponding rates varying from 43.4% (25  805 of 59 413 women, 43.0% to 43.8%) to 64.3% (364 of 566 women, 60.3% to 68.3%); and highest in multiparous women with previous caesarean section, with corresponding rates varying from 42.9% (3426 of 7993 women, 41.8% to 44.0%) to 66.3% (554 of 836 women, 63.0% to 69.5%).

CONCLUSIONS

Nulliparous women without risk factors have substantially higher rates of complicated birth than multiparous women without a previous caesarean section even if the latter have multiple risk factors. Grouping women first according to parity and previous mode of birth, and then within these groups according to presence of specific risk factors would provide greater and more informed choice to women, better targeting of interventions, and fewer transfers during labour than according to the presence of risk factors alone.

Women's characteristics and care outcomes of caseload midwifery care in the Netherlands: a retrospective cohort study

BACKGROUND

The maternity care system in the Netherlands is well known for its support of community-based midwifery. However, regular midwifery practices typically do not offer caseload midwifery care - one-to-one continuity of care throughout pregnancy and birth. Because we know very little about the outcomes for women receiving caseload care in the Netherlands, we compared caseload care with regular midwife-led care, looking at maternal and perinatal outcomes, including antenatal and intrapartum referrals to secondary (i.e., obstetrician-led) care.

METHODS

We selected 657 women in caseload care and 1954 matched controls (women in regular midwife-led care) from all women registered in the Dutch Perinatal Registry (Perined) who gave birth in 2015. To be eligible for selection the women had to be in midwife-led antenatal care beyond 28 gestational weeks. Each woman in caseload care was matched with three women in regular midwife-led care, using parity, maternal age, background (Dutch or non-Dutch) and region. These two cohorts were compared for referral rates, mode of birth, and other maternal and perinatal outcomes.

RESULTS

In caseload midwifery care, 46.9% of women were referred to obstetrician-led care (24.2% antenatally and 22.8% in the intrapartum period). In the matched cohort, 65.7% were referred (37.4% antenatally and 28.3% in the intrapartum period). In caseload care, 84.0% experienced a spontaneous vaginal birth versus 77.0% in regular midwife-led care. These patterns were observed for both nulliparous and multiparous women. Women in caseload care had fewer inductions of labour (13.2% vs 21.0%), more homebirths (39.4% vs 16.1%) and less perineal damage (intact perineum: 41.3% vs 28.2%). The incidence of perinatal mortality and a low Apgar score was low in both groups.

CONCLUSIONS

We found that when compared to regular midwife-led care, caseload midwifery care in the Netherlands is associated with a lower referral rate to obstetrician-led care - both antenatally and in the intrapartum period - and a higher spontaneous vaginal birth rate, with similar perinatal safety. The challenge is to include this model as part of the current effort to improve the quality of Dutch maternity care, making caseload care available and affordable for more women.

Oxytocin and emergency caesarean section in a mediumsized hospital in Pakistan: A cross-sectional study

INTRODUCTION

One of the most common complications during labor is prolonged labor (dystocia), which is associated with risks for the mother and fetus. Dystocia is usually treated with oxytocin, which is also used to induce labor. Oxytocin may not have the desired effect of progress and can negatively affect the fetus, thus resulting in an emergency caesarean section (CS). The aim of this study was to describe obstetric practice, use of oxytocin and its association with an emergency CS.

METHODS

A cross-sectional retrospective register study was conducted that included all women who gave birth during 2014 and 2015 at a hospital in a large city in Pakistan.

RESULTS

A total of 6652 women gave birth to 6767 newborns, 66.8% were multiparous and 33.2% primiparous women. Of the primiparous women, 78.9% had a spontaneous vaginal birth, 1.2% an elective CS and 14.4% an emergency CS. Of the multiparous women, 81.9% had a spontaneous vaginal birth, 8.0% an elective CS and 6.7% an emergency CS. Operative vaginal birth was 2.1% among primiparous and 0.2% among multiparous women. Oxytocin for induction or augmentation was administered to 60.0% of primiparous and 30.5% of multiparous women. Oxytocin during the first stage of labor was associated with an increased risk for emergency CS for both primiparous and multiparous women.

CONCLUSIONS

Despite the association between oxytocin and emergency CS, the CS rate was low in this hospital. The majority of the women gave birth vaginally, even with a breech presentation. Few operative vaginal births were performed.

Understanding childbirth as a complex salutogenic phenomenon: The EU COST BIRTH Action Special Collection

In 2014, the EU funded a four-year European Cooperation in Science and Technology (COST) Action to address the topic of childbirth. The COST Birth Action was a cross-European network, that brought together over 120 scientists, practitioners, activists and policy makers from 34 countries to work on intrapartum care. The central aim was to advance the state of research and practice in a specific area of great clinical and social importance, intrapartum care. The Action used inter and trans-disciplinary approaches to address birth from multiple perspectives and drew on complexity theory and the concept of salutogenesis (wellbeing). This special collection presents six papers produced from the Action and gives a sense of the range and depth of the work conducted. The Collection illustrates the knowledge that can be generated when a diverse group of people come together with a similar goals and perspectives.

Factors influencing utilisation of ‘free-standing’ and ‘alongside’ midwifery units for low-risk births in England: a mixed-methods study

Background

Midwifery-led units (MUs) are recommended for ‘low-risk’ births by the National Institute for Health and Care Excellence but according to the National Audit Office were not available in one-quarter of trusts in England in 2013 and, when available, were used by only a minority of the low-risk women for whom they should be suitable. This study explores why.

Objectives

To map the provision of MUs in England and explore barriers to and facilitators of their development and use; and to ascertain stakeholder views of interventions to address these barriers and facilitators.

Design

Mixed methods – first, MU access and utilisation across England was mapped; second, local media coverage of the closure of free-standing midwifery units (FMUs) were analysed; third, case studies were undertaken in six sites to explore the barriers and facilitators that have an impact on the development of MUs; and, fourth, by convening a stakeholder workshop, interventions to address the barriers and facilitators were discussed.

Setting

English NHS maternity services.

Participants

All trusts with maternity services.

Interventions

Establishing MUs.

Main outcome measures

Numbers and types of MUs and utilisation of MUs.

Results

Births in MUs across England have nearly tripled since 2011, to 15% of all births. However, this increase has occurred almost exclusively in alongside units, numbers of which have doubled. Births in FMUs have stayed the same and these units are more susceptible to closure. One-quarter of trusts in England have no MUs; in those that do, nearly all MUs are underutilised. The study findings indicate that most trust managers, senior midwifery managers and obstetricians do not regard their MU provision as being as important as their obstetric-led unit provision and therefore it does not get embedded as an equal and parallel component in the trust’s overall maternity package of care. The analysis illuminates how provision and utilisation are influenced by a complex range of factors, including the medicalisation of childbirth, financial constraints and institutional norms protecting the status quo.

Limitations

When undertaking the case studies, we were unable to achieve representativeness across social class in the women’s focus groups and struggled to recruit finance directors for individual interviews. This may affect the transferability of our findings.

Conclusions

Although there has been an increase in the numbers and utilisation of MUs since 2011, significant obstacles remain to MUs reaching their full potential, especially FMUs. This includes the capacity and willingness of providers to address women’s information needs. If these remain unaddressed at commissioner and provider level, childbearing women’s access to MUs will continue to be restricted.

Future work

Work is needed on optimum approaches to improve decision-makers’ understanding and use of clinical and economic evidence in service design. Increasing women’s access to information about MUs requires further studies of professionals’ understanding and communication of evidence. The role of FMUs in the context of rural populations needs further evaluation to take into account user and community impact.

Intrapartum and neonatal mortality in low-risk term women in midwife-led care and obstetrician-led care at the onset of labor: A national matched cohort study

INTRODUCTION

Midwife-led models of care have been the subject of debate for many years. We conducted a study to compare intrapartum and neonatal mortality rates in midwife-led (primary) vs obstetrician-led (secondary) care at the onset of labor in low-risk term women.

MATERIAL AND METHODS

We performed an unmatched and a propensity score matched cohort study using data from the national perinatal audit registry (PAN) and from the national perinatal registry (PERINED) of the Netherlands. We included women with singleton pregnancies (without congenital anomalies or antepartum fetal death) who gave birth at term between 2010 and 2012. We excluded the following major risk factors: non-vertex position of the fetus, previous cesarean birth, hypertension, diabetes mellitus, prolonged rupture of membranes (≥24 hours), vaginal bleeding in the second half of pregnancy, nonspontaneous start of labor and post-term pregnancy (≥42 weeks). The primary outcome was intrapartum or neonatal mortality up to 28 days after birth. Secondary outcome measures were mode of delivery and a 5-minute Apgar score <7.

RESULTS

We included 259 211 women. There were 100/206 642 (0.48‰) intrapartum and neonatal deaths in the midwife group and 23/52 569 (0.44‰) in the obstetrician group (odds ratio [OR] 1.11, 95% CI 0.70-1.74). Propensity score matched analysis showed mortality rates of 0.49‰ (26/52 569) among women in midwife-led care and 0.44‰ (23/52 569) for women in obstetrician-led care (OR 1.13, 95% CI 0.65-1.98). In the midwife group there were significantly lower rates of vaginal instrumental deliveries (8.4% vs 13.0%; matched OR 0.65, 95% CI 0.62-0.67) and intrapartum cesarean sections (2.6% vs 8.2%; matched OR 0.32, 95% CI 0.30-0.34), and fewer neonates with low Apgar scores (<7 after 5 minutes) (0.69% vs 1.11%; matched OR 0.61, 95% CI 0.53-0.69).

CONCLUSIONS

Among low-risk term women, there were comparable intrapartum and neonatal mortality rates for women starting labor in midwife-led vs obstetrician-led care, with lower intervention rates and fewer low Apgar scores in the midwife group.

Relation between Length of Exposure to Epidural Analgesia during Labour and Birth Mode

Objective: To appraise the relationship between the length of exposure to epidural analgesia and the risk of non-spontaneous birth, and to identify additional risk factors. This study is framed within the MidconBirth project. Study design: A multicentre prospective study was conducted between July 2016 and November 2017 in three maternity hospitals in different Spanish regions. The independent variable of the study was the length of exposure to epidural analgesia, and the dependent variable was the type of birth in women with uncomplicated pregnancies. The data was analyzed separately by parity. A multivariate logistic regression was performed. The odds ratios (OR), using 95% confidence intervals (CI) were constructed. Main outcome measures: During the study period, 807 eligible women gave birth. Non-spontaneous births occurred in 29.37% of the sample, and 75.59% received oxytocin for augmentation of labour. The mean exposure length to epidural analgesia when non-spontaneous birth happened was 8.05 for primiparous and 6.32 for multiparous women (5.98 and 3.37 in spontaneous birth, respectively). A logistic regression showed the length of exposure to epidural during labour was the major predictor for non-spontaneous births in primiparous and multiparous women followed by use of oxytocin (multiparous group). Conclusions: The length of exposure to epidural analgesia during labour is associated with non-spontaneous births in our study. It highlights the need for practice change through the development of clinical guidelines, training programs for professionals and the continuity of midwifery care in order to support women to cope with labour pain using less invasive forms of analgesia. Women also need to be provided with evidence-based information.

Health system factors and caesarean sections in Kosovo: a cross-sectional study

OBJECTIVE

To investigate the association of caesarean section rates with the health system characteristics in the public hospitals of Kosovo.

DESIGN

Cross-sectional survey.

SETTING

Five largest public hospitals in Kosovo.

PARTICIPANTS

859 women with low-risk deliveries who delivered from April to May 2015 in five public hospitals in Kosovo.

OUTCOME MEASURES

The prespecified outcomes were the crude and adjusted OR of births delivered with caesarean section by health system characteristics such as delivery by the physician who provided antenatal care, health insurance status and other. Additional prespecified outcomes were caesarean section rates and crude ORs for delivery with caesarean in each public hospital.

RESULTS

Women with personal monthly income had increased odds for caesarean (OR 1.55, 95% CI 1.06 to 2.27), as did women with private health insurance coverage (OR 3.44, 95% CI 1.20 to 9.85). Women instructed by a midwife on preparation for delivery had decreasing odds (OR 0.32, 95% CI 0.19 to 0.51) while women having preference for a caesarean had increasing odds for delivery with caesarean (OR 3.84, 95% CI 1.96 to 7.51). The odds for caesarean increased also in the case of delivery by a physician who provided antenatal care (OR 2.06, 95% CI 1.16 to 3.67) and delivery during office hours (OR 2.36, 95% CI 1.37 to 4.05), while delivery at the University Clinical Centre of Kosovo decreased the odds for caesarean (OR 0.46, 95% CI 0.24 to 0.90).

CONCLUSIONS

We found that several health system characteristics are associated with the increase of caesarean sections in a low-risk population of delivering women in public hospitals of Kosovo. These findings should be explored further and addressed via policy measures that would tackle provision of unnecessary caesareans. The study findings could assist Kosovo to develop corrective policies in addressing overuse of caesareans and may provide useful information for other middle-income countries.

Induction of labour at 41 weeks versus expectant management until 42 weeks (INDEX): multicentre, randomised non-inferiority trial

OBJECTIVE

To compare induction of labour at 41 weeks with expectant management until 42 weeks in low risk women.

DESIGN

Open label, randomised controlled non-inferiority trial.

SETTING

123 primary care midwifery practices and 45 hospitals (secondary care) in the Netherlands, 2012-16.

PARTICIPANTS

1801 low risk women with an uncomplicated singleton pregnancy: randomised to induction (n=900) or to expectant management until 42 weeks (n=901).

INTERVENTIONS

Induction at 41 weeks or expectant management until 42 weeks with induction if necessary.

PRIMARY OUTCOME MEASURES

Primary outcome was a composite of perinatal mortality and neonatal morbidity (Apgar score <7 at five minutes, arterial pH <7.05, meconium aspiration syndrome, plexus brachialis injury, intracranial haemorrhage, and admission to a neonatal intensive care unit (NICU). Secondary outcomes included maternal outcomes and mode of delivery. The null hypothesis that expectant management is inferior to induction was tested with a non-inferiority margin of 2%.

RESULTS

Median gestational age at delivery was 41 weeks+0 days (interquartile range 41 weeks+0 days-41 weeks+1 day) for the induction group and 41 weeks+2 days (41 weeks+0 days-41 weeks+5 days) for the expectant management group. The primary outcome was analysed for both the intention-to-treat population and the per protocol population. In the induction group, 15/900 (1.7%) women had an adverse perinatal outcome versus 28/901 (3.1%) in the expectant management group (absolute risk difference -1.4%, 95% confidence interval -2.9% to 0.0%, P=0.22 for non-inferiority). 11 (1.2%) infants in the induction group and 23 (2.6%) in the expectant management group had an Apgar score <7 at five minutes (relative risk (RR) 0.48, 95% CI 0.23 to 0.98). No infants in the induction group and three (0.3%) in the expectant management group had an Apgar score <4 at five minutes. One fetal death (0.1%) occurred in the induction group and two (0.2%) in the expectant management group. No neonatal deaths occurred. 3 (0.3%) neonates in the induction group versus 8 (0.9%) in the expectant management group were admitted to an NICU (RR 0.38, 95% CI 0.10 to 1.41). No significant difference was found in composite adverse maternal outcomes (induction n=122 (13.6%) v expectant management n=102 (11.3%)) or in caesarean section rate (both groups n=97 (10.8%)).

CONCLUSIONS

This study could not show non-inferiority of expectant management compared with induction of labour in women with uncomplicated pregnancies at 41 weeks; instead a significant difference of 1.4% was found for risk of adverse perinatal outcomes in favour of induction, although the chances of a good perinatal outcome were high with both strategies and the incidence of perinatal mortality, Apgar score <4 at five minutes, and NICU admission low.

Analgesia during Labor and Vaginal Birth among Women with Severe Maternal Morbidity: Secondary Analysis from the WHO Multicountry Survey on Maternal and Newborn Health

Aim

To evaluate the use of analgesia for vaginal birth, in women with and without severe maternal morbidity (SMM) and to describe sociodemographic, clinical, and obstetric characteristics and maternal and perinatal outcomes associated with labor analgesia.

Methods

Secondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health (WHO-MCS), a global cross-sectional study performed between May 2010 and December 2011 in 29 countries. Women who delivered vaginally and had an SMM were included in this analysis and were then divided into two groups: those who received and those who did not receive analgesia for labor/delivery. We further compared maternal characteristics and maternal and perinatal outcomes between these two groups.

Results

From 314,623 women originally included in WHO-MCS, 9,788 developed SMM and delivered vaginally, 601 (6.1%) with analgesia and 9,187 (93.9%) without analgesia. Women with SMM were more likely to receive analgesia than those who did not experience SMM. Global distribution of SMM was similar; however, the use of analgesia was less prevalent in Africa. Higher maternal education, previous cesarean section, and nulliparity were factors associated with analgesia use. Analgesia was not an independent factor associated with an increase of severe maternal outcome (Maternal Near Miss + Maternal Death).

Conclusions

The overall use of analgesia for vaginal delivery is low but women with SMM are more likely to receive analgesia during labor. Social conditions are closely linked with the likelihood of having analgesia during delivery and such a procedure is not associated with increased adverse maternal outcomes. Expanding the availability of analgesia in different levels of care should be a concern worldwide.

The effect of medical and operative birth interventions on child health outcomes in the first 28 days and up to 5 years of age: A linked data population-based cohort study

BACKGROUND

Spontaneous vaginal birth rates are decreasing worldwide, while cesarean delivery, instrumental births, and medical birth interventions are increasing. Emerging evidence suggests that birth interventions may have an effect on children's health. Therefore, the aim of our study was to examine the association between operative and medical birth interventions on the child's health during the first 28 days and up to 5 years of age.

METHODS

In New South Wales (Australia), population-linked data sets were analyzed, including data on maternal characteristics, child characteristics, mode of birth, interventions during labor and birth, and adverse health outcomes of the children (ie, jaundice, feeding problems, hypothermia, asthma, respiratory infections, gastrointestinal disorders, other infections, metabolic disorder, and eczema) registered with the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification codes. Logistic regression analyses were performed for each adverse health outcome.

RESULTS

Our analyses included 491 590 women and their children; of those 38% experienced a spontaneous vaginal birth. Infants who experienced an instrumental birth after induction or augmentation had the highest risk of jaundice, adjusted odds ratio (aOR) 2.75 (95% confidence interval [CI] 2.61-2.91) compared with spontaneous vaginal birth. Children born by cesarean delivery were particularly at statistically significantly increased risk for infections, eczema, and metabolic disorder, compared with spontaneous vaginal birth. Children born by emergency cesarean delivery showed the highest association for metabolic disorder, aOR 2.63 (95% CI 2.26-3.07).

CONCLUSION

Children born by spontaneous vaginal birth had fewer short- and longer-term health problems, compared with those born after birth interventions.

Obstetric practices in planned home births assisted in Brazil

OBJECTIVE

To describe obstetric practices in planned home births, assisted by qualified professionals in Brazil.

METHOD

This is a descriptive study, with data collected in an online bank maintained by 49 professionals from December 2014 to November 2015, in which the target population was women and newborns assisted in home births. Data were analyzed through descriptive statistics.

RESULTS

A total of 667 women and 665 newborns were included. Most of the women gave birth at home (84.4%), in a nonlithotomic position (99.1%); none underwent episiotomy; 32.3% had intact perineum; and 37.8% had first-degree lacerations, some underwent amniotomy (5.4%), oxytocin administration (0.4%), and Kristeller's maneuver (0.2%); 80.8% of the women with a previous cesarean section had home birth. The rate of transfer of parturients was 15.6%, of puerperal women was 1.9%, and of neonates 1.6%. The rate of cesarean section in the parturients that started labor at home was 9.0%.

CONCLUSION

The obstetric practices taken are consistent with the scientific evidence; however, unnecessary interventions are still performed. The rates of cesarean sections and maternal and neonatal transfers are low. Home can be a place of birth option for women seeking a physiological delivery.
