A comparison of intrapartum interventions and adverse outcomes by parity in planned freestanding midwifery unit and alongside midwifery unit births: secondary analysis of 'low risk' births in the birthplace in England cohort

Intrapartum Quality of Care among Healthy Women: A Population-Based Cohort Study in an Italian Region

Although the quality of care during childbirth is a maternity service's goal, less is known about the impact of the birth setting dimension on provision of care, defined as evidence-based intrapartum midwifery practices. This study's aim was to investigate the impact of hospital birth volume (≥1000 vs. <1000 births/year) on intrapartum midwifery care and perinatal outcomes. We conducted a population-based cohort study on healthy pregnant women who gave birth between 2018 and 2022 in Lombardy, Italy. A total of 145,224 (41.14%) women were selected from nationally linked databases. To achieve the primary aim, log-binomial regression models were constructed. More than 70% of healthy pregnant women gave birth in hospitals (≥1000 births/year) where there was lower use of nonpharmacological coping strategies, higher likelihood of epidural analgesia, episiotomy, birth companion's presence at birth, skin-to-skin contact, and first breastfeeding within 1 h (p-value < 0.001). Midwives attended almost all the births regardless of birth volume (98.80%), while gynecologists and pediatricians were more frequently present in smaller hospitals. There were no significant differences in perinatal outcomes. Our findings highlighted the impact of the birth setting dimension on the provision of care to healthy pregnant women.

First alongside midwifery led unit in a high complexity public hospital in Spain: Maternal and neonatal outcomes

PROBLEM

Midwifery led units are rare in Spain.

BACKGROUND

Midwife-Led Care (MLC) is a widely extended model of care and, within this, the alongside midwifery-led units (AMLU) are those hospital-based and located in close connection with obstetric units. In Spain, CL is the first center belonging to the National Health System of these characteristics.

AIM

To evaluate the first year of activity of this pioneering unit.

METHODS

An observational cross-sectional study was carried out to assess maternal and neonatal outcomes of births facilitated at CL by comparing with those births that fulfilled the criteria to be admitted at the AMLU but were assisted at the standard obstetric care unit of the hospital.

FINDINGS

174 (20,3%) women and birthing people decided to give birth at CL, whereas 684 (79,7%) gave birth at the Obstetric Unit of the Hospital. Women assisted at the AMLU had lower intervention rates (episiotomy, epidural analgesia) and a higher rate of breastfeeding practice. There were no statistical differences in maternal outcomes (postpartum hemorrhage, third-or-four-degree laceration) or neonatal outcomes (Apgar< 7 at 5 min; birth weight < 2500 gr; macrosomia; shoulder dystocia, neonatal care transfer).

DISCUSSION

There were differences in transfers from MLU to OU between nulliparous and multiparous; the main reason for transfer is the request for analgesia. Epidural analgesia should be considered when analyzing maternal outcomes.

CONCLUSION

An alongside midwifery-led unit is a safe option with a low incidence of complications. This model of care can be positively implemented at the Public Healthcare System.

Adaptation and validation of the Portuguese version of the provider attitudes towards planned home birth (PAPHB) Scale

Maternity health care professionals' attitudes on the option of home birth can influence the choices and decisions women and their partners make about place of birth. Midwives are particularly influential in this space. The study outlined in this paper aimed to translate and validate the Provider Attitudes towards Planned Home Birth (PAPHB) scale questionnaire for use in the Portuguese maternity context.

METHODS

A total of 118 Portuguese midwives were selected through intentional sampling. The procedure was divided into two phases. In the first phase, a triple translation from the original language into Portuguese and a cross-cultural adaptation of the Provider Attitudes towards Planned Home Birth (PAPHB) scale were carried out, obtaining three versions of the same questionnaire. The second phase consisted of the validation of the questionnaire, for which the Provider Attitudes towards Planned Home Birth (PAPHB) scale was submitted to a panel of 20 experts and to a pilot test. Subsequently, the reliability and statistical validity of the scale were evaluated.

RESULTS

After content analysis, the results confirmed a four-dimensional structure with a Cronbach's α value of 0.933 for the Provider Attitudes towards Planned Home Birth (PAPHB) scale as a whole, showing good internal consistency. Finally, a bivariate analysis was carried out identifying associations between variables and midwives' attitudes towards home birth. Positive attitudes towards homebirth were strongly influenced by previous clinical experience and exposure to home birth during midwives' academic education.

CONCLUSION

The 18-item scale is a reliable and valid tool to quantify attitudes towards planned home births in Portugal as the results obtained in the study showed very good internal consistency.

Women's reasons and motivations around planning a home birth with a qualified midwife in Spain

AIMS

The aim of this study was to describe and understand the reasons and motivations that lead a woman to choose home birth in Spain.

DESIGN

A qualitative study based on Gadamer's hermeneutic phenomenology was carried out.

METHODS

In-depth interviews were conducted with 24 women who had planned a home birth in the last year. The recruitment phase was carried out over a 3-week period during the month of March 2021. Inductive analysis was used to find themes based on the data obtained.

RESULTS

Four main themes emerged from the data analysis: (1) Women's home birth decision making, (2) Partner as the main support, (3) Need to prepare for childbirth and (4) Reasons for choosing home birth.

CONCLUSION

The women in this study spent a lot of time and dedication to choose the place where they would give birth. According to this research, decision making is influenced by multiple factors, both positive and negative, such as women's individual beliefs and values. The main reasons why women chose a home birth were the intimacy and security of the home, the accompaniment and the desire for a natural and free birth.

IMPACT

This study adds knowledge about the factors that influence the decision of women who choose home birth in Spain and the reasons and motivations that lead them to do so. In addition, it raises new questions about the satisfaction of women giving birth in the hospital as well as outside the hospital, and the quality of service provided by health professionals in the current Spanish public maternity system.

Planned Home Birth in Low-Risk Pregnancies in Spain: A Descriptive Study

Previous studies have shown that planned home birth in low-risk pregnancies is a generally safe option. However nowadays, only 0.5 percent of deliveries have been at home in Spain. This study sought to understand the characteristics of planned home births with qualified healthcare professionals in low-risk pregnancies and their results on maternal and neonatal health in the Balearic Islands. The study followed a retrospective descriptive design to investigate planned home births from 1989 to 2019 (n = 820). Sociodemographic data of women, healthcare professional intervention rates, and maternal/fetal morbidity/mortality results were collected. Statistical analysis of the results was performed using the IBM SPSS Version 25 software package. The results indicated that women with low-risk pregnancies who planned home births with a qualified midwife had a higher probability of spontaneous vaginal birth delivery and positive maternal health results. Furthermore, the risk of hospital transfer was low (10.7%) and the rate of prolonged breastfeeding (>1 year) was extremely high (99%). Moreover, the study showed that planned home births can be generally associated with fetal well-being. The conclusions and implications of this study are that planned home births in low-risk pregnancies attended by qualified midwives in the Balearic Islands achieve positive results in both maternal and newborn health, as well as low rates of obstetric intervention.

Birth Outcomes of Women with Obesity Enrolled for Care at Freestanding Birth Centers in the United States

Introduction

Current US guidelines for the care of women with obesity generalize obesity‐related risks to all women regardless of overall health status and assume that birth will occur in hospitals. Perinatal outcomes for women with obesity in US freestanding birth centers need documentation.

Methods

Pregnancies recorded in the American Association of Birth Centers Perinatal Data Registry were analyzed (n = 4,455) to form 2 groups of primiparous women (n = 964; 1:1 matching of women with normal body mass indices [BMIs] and women with obese BMIs [>30]), using propensity score matching to address the imbalance of potential confounders. Groups were compared on a range of outcomes. Differences between groups were evaluated using χ² test for categorical variables and Student's t test for continuous variables. Paired t test and McNemar's test evaluated the differences among the matched pairs.

Results

The majority of women with obese BMIs experienced uncomplicated perinatal courses and vaginal births. There were no significant differences in antenatal complications, proportion of prolonged pregnancy, prolonged first and second stage labor, rupture of membranes longer than 24 hours, postpartum hemorrhage, or newborn outcomes between women with obese BMIs and normal BMIs. Among all women with intrapartum referrals or transfers (25.3%), the primary indications were prolonged first stage or second stage (55.4%), inadequate pain relief (14.8%), client choice or psychological issue (7.0%), and meconium (5.3%). Primiparous women with obesity who started labor at a birth center had a 30.7% transfer rate and an 11.1% cesarean birth rate.

Discussion

Women with obese BMIs without medical comorbidity can receive safe and effective midwifery care at freestanding birth centers while anticipating a low risk for cesarean birth. The risks of potential, obesity‐related perinatal complications should be discussed with women when choosing place of birth; however, pregnancy complicated by obesity must be viewed holistically, not simply through the lens of obesity.

Local guidelines for admission to UK midwifery units compared with national guidance: A national survey using the UK Midwifery Study System (UKMidSS)

OBJECTIVES

To describe the extent to which local guidelines for admission to UK midwifery units align with national guidance; to describe variation in individual admission criteria; and to describe the extent to which alongside midwifery units (AMUs) are the default option for eligible women.

DESIGN

National cross-sectional survey.

SETTING

All 122 UK maternity services with midwifery units, between October 2018 and February 2019.

OUTCOME MEASURES

Alignment of local admission guidelines with national guidance (NICE CG190); frequency and nature of variation in individual admission criteria; percentage of services with AMU as default birth setting for eligible women.

RESULTS

Admission guidelines were received from 87 maternity services (71%), representing 153 units, and we analysed 85 individual guideline documents. Overall, 92% of local admission guidelines varied from national guidance; 76% contained both some admission criteria that were 'more inclusive' and some that were 'more restrictive' than national guidance. The most common 'more inclusive' admission criteria, occurring in 40-80% of guidelines, were: explicit admission of women with parity ≥4; aged 35-40yrs; with a BMI 30-35kg/m2; selective admission of women with a BMI 35-40kg/m2; Group B Streptococcus carriers; and those undergoing induction of labour. The most common 'more restrictive' admission criteria, occurring in around 30% of guidelines, excluded women who: declined blood products; had experienced female genital cutting; were aged <16yrs; or had not attended for regular antenatal care. Over half of services (59%) reported the AMU as the default option for healthy women with straightforward pregnancies.

CONCLUSIONS

The variation in local midwifery unit admission criteria found in this study represents a potentially confusing and inequitable basis for women making choices about planned place of birth. A review of national guidance may be indicated and where a lack of relevant evidence underlies variation in admission criteria, further research by planned place of birth is required.

Complications of planned home births in the Czech Republic between 2016‒2017

OBJECTIVE

This study aimed to analyze the complications of planned home births treated at healthcare facilities in the Czech Republic.

METHODS

This prospective cohort observational study is based on analysis of women hospitalized with complications related to planned home deliveries in the Czech Republic between 2016 and 2017. The data were collected using an online form made accessible to the directors of all maternity hospitals in the Czech Republic. The results were statistically evaluated.

RESULTS

We identified 45 complications during planned home deliveries. Complications occurred most often among women living in largely populated cities with higher levels of education. Overall, 40% of patients did not receive routine antenatal care, and 38% of women gave birth after the 41st week of pregnancy. In 60% of cases, no professionals attended the birth. Hospital transfer frequencies were 42% after delivery, 36% at third-stage labour, 11% first-stage labour, 9% second-stage labour, and 2% before delivery. We recorded four neonatal deaths and one severe newborn morbidity. There was one maternal death unrelated to the home-birthing process and six cases of severe maternal haemorrhagic shock requiring intensive care.

CONCLUSION

Complications of planned home births occurred more frequently in women living in largely populated cities and with higher education levels. Planned home births were also observed among women who were at a higher risk of complications. Risk factors included nulliparity, postdate pregnancy, and lack of prenatal care. Hospital transfers occurred most often in the third stage of labour and postpartum.

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.

Freestanding Midwife-Led Units: A Narrative Review

Background

Strengthening of midwives' position and support for freestanding birth centers, frequently referred to as Freestanding Midwife-led Units (FMUs), raise hopes for a return to humanized labor. Our study aimed to review published evidence regarding FMUs to systematize the knowledge of their functioning and to identify potential gaps in this matter.

Materials and Methods

A structured integrative review of theoretical papers and empirical studies was conducted. The literature search included MEDLINE, Cochrane, Scopus, and Embase databases. The analysis included papers published in 1977-2017. Relevant documents were identified using various combinations of search terms and standard Boolean operators. The search included titles, abstracts, and keywords. Additional records were found through a manual search of reference lists from extracted papers.

Results

Overall, 56 out of 107 originally found articles were identified as eligible for the review. Based on the critical analysis of published data, six groups of research problems were identified and discussed, namely, 1) specifics of FMUs, 2) costs of perinatal care at FMUs, 3) FMUs as a place for midwife education, 4) FMUs from midwives' perspective, 5) perinatal, maternal, and neonatal outcomes, and 6) FMUs from the perspective of a pregnant woman.

Conclusions

FMUs offers a home-like environment and complex midwifery support for women with uncomplicated pregnancies. Although emergency equipment is available as needed, FMU birth is considered a natural spontaneous process. Midwives' supervision over low-risk labors may provide many benefits, primarily related to lower medicalization and fewer medical interventions than in a hospital setting.

Understanding the conditions that influence the roles of midwives in Ontario, Canada's health system: an embedded single-case study

BACKGROUND

Despite the significant variability in the role and integration of midwifery across provincial and territorial health systems, there has been limited scholarly inquiry into whether, how and under what conditions midwifery has been assigned roles and integrated into Canada's health systems.

METHODS

We use Yin's (2014) embedded single-case study design, which allows for an in-depth exploration to qualitatively assess how, since the regulation of midwives in 1994, the Ontario health system has assigned roles to and integrated midwives as a service delivery option. Kingdon's agenda setting and 3i + E theoretical frameworks are used to analyze two recent key policy directions (decision to fund freestanding midwifery-led birth centres and the Patients First primary care reform) that presented opportunities for the integration of midwives into the health system. Data were collected from key informant interviews and documents.

RESULTS

Nineteen key informant interviews were conducted, and 50 documents were reviewed in addition to field notes taken during the interviews. Our findings suggest that while midwifery was created as a self-regulated profession in 1994, health-system transformation initiatives have restricted the profession's integration into Ontario's health system. The policy legacies of how past decisions influence the decisions possible today have the most explanatory power to understand why midwives have had limited integration into interprofessional maternity care. The most important policy legacies to emerge from the analyses were related to payment mechanisms. In the medical model, payment mechanisms privilege physician-provided and hospital-based services, while payment mechanisms in the midwifery model have imposed unintended restrictions on the profession's ability to practice in interprofessional environments.

CONCLUSIONS

This is the first study to explain why midwives have not been fully integrated into the Ontario health system, as well as the limitations placed on their roles and scope of practice. The study also builds a theoretical understanding of the integration process of healthcare professions within health systems and how policy legacies shape service delivery options.

Effects of Birthing Room Design on Maternal and Neonate Outcomes: A Systematic Review

Aim:

To summarize, categorize, and describe published research on how birthing room design influences maternal and neonate physical and emotional outcomes.

Background:

The physical healthcare environment has significant effects on health and well-being. Research indicates that birthing environments can impact women during labor and birth. However, summaries of the effects of different environments around birth are scarce.

Methods:

We conducted a systematic review, searching 10 databases in 2016 and 2017 for published research from their inception dates, on how birthing room design influences maternal and neonate physical and emotional outcomes, using a protocol agreed a priori. The quality of selected studies was assessed, and data were extracted independently by pairs of authors and described in a narrative analysis.

Results:

In total, 3,373 records were identified and screened by title and abstract; 2,063 were excluded and the full text of 278 assessed for analysis. Another 241 were excluded, leaving 15 articles presenting qualitative and quantitative data from six different countries on four continents. The results of the analysis reveal four prominent physical themes in birthing rooms that positively influence on maternal and neonate physical and emotional outcomes: (1) means of distraction, comfort, and relaxation; (2) raising the birthing room temperature; (3) features of familiarity; and (4) diminishing a technocratic environment.

Conclusions:

The evidence on how birthing environments affect outcomes of labor and birth is incomplete. There is a crucial need for more research in this field.

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.

An analysis of media reporting on the closure of freestanding midwifery units in England

PROBLEM

Despite clinical guidelines and policy promoting choice of place of birth, 14 Freestanding Midwifery Units were closed between 2008 and 2015, closures reported in the media as justified by low use and financial constraints.

BACKGROUND

The Birthplace in England Programme found that freestanding midwifery units provided the most cost-effective birthplace for women at low risk of complications. Women planning birth in a freestanding unit were less likely to experience interventions and serious morbidity than those planning obstetric unit birth, with no difference in outcomes for babies.

METHODS

This paper uses an interpretative technique developed for policy analysis to explore the representation of these closures in 191 news articles, to explore the public climate in which they occurred.

FINDINGS AND DISCUSSION

The articles focussed on underuse by women and financial constraints on services. Despite the inclusion of service user voices, the power of framing was held by service managers and commissioners. The analysis exposed how neoliberalist and austerity policies have privileged representation of individual consumer choice and market-driven provision as drivers of changes in health services. This normative framing presents the reasons given for closure as hard to refute and cultural norms persist that birth is safest in an obstetric setting, despite evidence to the contrary.

CONCLUSION

The rise of neoliberalism and austerity in contemporary Britain has influenced the reform of maternity services, in particular the closure of midwifery units. Justifications given for closure silence other narratives, predominantly from service users, that attempt to present women's choice in terms of rights and a social model of care.
