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

What if something goes wrong? A grounded theory study of parents’ decision-making processes around mode of breech birth at term gestation

Objective. To explore factors that influence parents' decision-making for mode of breech birth at term gestation. Design. A grounded theory study conducted using a constructivist approach. Semi-structured telephone interviews were recorded and transcribed verbatim and analysed using the software NVivo for Mac version 11.4.0. Setting. England, UK. Participants. Twelve parents with breech presentation confirmed by ultrasound at ≥36+0 weeks gestation were recruited from several UK social media forums. Findings. Two core themes impacting on a parent's decision-making process for term breech birth were identified. Firstly, a framework of potential influences including partner and relationship, family and friends, health professionals, own birth culture, self, shared experiences and the time available for decision-making. Secondly, mortality salience, or parental focus on risk of potential injury or death associated with birth, was found to be central to every participant's narrative. Key conclusions. This study highlights the individuality and wider framework of parent's decision-making influences for term breech birth, and demonstrates to care providers the conflicted emotions that may be experienced. The findings of this study may guide midwives and other professionals in providing person-centered, non-judgmental, balanced and evidence-based mode of term breech birth counselling. Implications for practice. Health professionals should adopt a parentcentred approach to counselling for mode of term breech birth, considering parents' wider influences in their decision-making and the fear of injury or death surrounding both vaginal breech birth and caesarean section. They can also facilitate parents to understand the influences that might be guiding their own decision-making

Intrapartum birthing pool use in the UK

Over past centuries, childbirth has become increasingly medicalised, with a shift to hospital births and an overuse of interventions for women at low risk of childbirth complication. In response, there has been a move towards normalising birth which has grown in strength over recent years. In this thesis, I describe a programme of research which aimed to examine whether intrapartum birthing pool use could make an important contribution to normalising childbirth for low risk women. Maternity stakeholders differ in their views of intrapartum birthing pool use, with some emphasising its potential to reduce interventions and increase spontaneous birth and others raising concerns that birthing pool use, particularly waterbirth, predisposes women and their newborn to an increased risk of adverse events and outcomes The focus of my programme of research was therefore on examining the efficacy and safety of intrapartum birthing pool use, and its potential contribution to normalising childbirth for healthy women. In the first stage of my research programme, I analysed prospectively collected data for 8,924 nulliparous and multiparous women who used a birthing pool during labour in their planned place of birth. In the second stage¸ I explored the possibility of comparing intrapartum interventions and outcomes for women who used a birthing pool and women who could have, but chose not to use a birthing pool in one obstetric unit. Having found the unit was not representative of other obstetric units, in the third stage I used a bespoke dataset comprising routinely collected maternity data collated by Hospital Episode Statistics (HES) as a comparator for the birthing pool data. This research found that, for the birthing pool sample, adverse maternal and newborn outcomes were rare, and there were no differences in interventions and outcomes between care settings for multiparae or newborn. Comparisons with HES data showed significantly more birthing pool women had a spontaneous birth. This allays concerns over safety and supports the conclusion that intrapartum birthing pool use can make an important contribution to normalising birth

Factors Associated With Normal Physiologic Birth for Women Who Labor In Water: A Secondary Analysis of A Prospective Observational Study

Introduction: Research to understand factors associated with normal physiologic birth (unassisted vaginal birth, spontaneous labor onset without epidural analgesia, spinal, or general anesthetic, without episiotomy) is required. Laboring and/or giving birth in water has been shown to be associated with a high proportion of physiologic birth but with little understanding of factors that may influence this outcome. This study explored factors associated with normal physiologic birth for women who labored in water. Methods: We conducted a secondary analysis of a UK-based prospective observational study of 8064 women at low risk of childbirth complications who labored in water. Consecutive women were recruited from birth settings in England, Scotland, and Northern Ireland. Planned place of birth, maternal characteristics, intrapartum events, and maternal and neonatal outcomes were measured. Univariable and multivariable logistic regression modelling explored factors associated with normal physiologic birth. Results: In total, 5758 (71.4%) of women who labored in water had a normal physiologic birth. Planned birth in the community (adjusted odds ratio [aOR], 2.58; 95% CI, 2.22-2.99) or at an alongside midwifery unit (aOR, 1.21; 95% CI, 1.04-1.41) was positively associated with normal physiologic birth compared with planned birth in an obstetric unit. Duration of second stage (aOR, 0.66; 95% CI, 0.62-0.70), duration in the pool [aOR, 0.93; 95% CI, 0.90-0.96), and birth weight of the neonate (aOR, 0.74; 95% CI, 0.65-0.85) were negatively associated with normal physiologic birth. Parity was not associated with normal physiologic birth in multivariate analyses. Discussion: Our findings largely reflected wider research, both in and out of water. We found midwifery-led birth settings may increase the likelihood of normal physiologic birth among healthy women who labor in water, irrespective of parity. This association supports growing evidence demonstrating the importance of planned place of birth on reducing intervention rates and adds to research on labor and birth in water

Predictors of obstetric anal sphincter injury during waterbirth: A secondary analysis of a prospective observational study

Introduction and Hypothesis: Obstetric Anal Sphincter Injury (OASI) during childbirth is associated with urino-genital pain and dysfunction. Waterbirth is a popular birth choice for women, but controversy remains around the risk of OASI during waterbirth. This study reports on the incidence of OASI, and factors associated with OASI, for a cohort of women who gave birth in water. Methods: This secondary analysis used prospectively collected data from 2,908 women who gave birth in water in the hospital setting. Incidence of OASI was calculated. Univariable and multivariable logistic regression analysis evaluated factors associated with OASI. Results: The incidence of OASI was 1.9% (95% CI 1.4, 2.4) for all women. In nulliparae it was higher (3.2%, 95% CI 2.3, 4.3), than for multiparae (0.9%, 95% CI 0.5, 1.4). In the multivariable analysis two variables were associated with OASI; multiparity was negatively associated with OASI (aOR 0.24, 95% CI 0.12, 0.50, p < 0.001), and birth weight was positively associated with OASI (aOR 1.001, 95% CI 1.000, 1.002, p = 0.02). A ‘hands-on’ technique was used during only 13% of births. Birth position supporting a flexible sacrum did not influence OASI risk. Conclusions: A low incidence of OASI was found for this cohort of women. The low proportion of midwives using a hands-on technique suggests that it may not be required in waterbirth.

Developing and evaluating an online learning tool to improve midwives’ accuracy of visual estimation of blood loss during waterbirth: an experimental study

Objective: The principal objective was to test the effectiveness of an online learning tool to improve midwives’ accuracy of blood loss estimations in a birthing pool environment. The secondary objective was to assess the acceptability of the online learning tool to the midwives using it. Design: A one group pre-test, post-test experiment with immediate and six weeks follow-up to test ability together with an online questionnaire to assess perceived usefulness of an online learning tool. Setting: A large NHS maternity hospital comprising an acute care obstetric unit, a small district unit labour ward, one alongside midwifery-led unit and three freestanding midwifery-led units. Participants: Volunteer NHS employed midwives who had experience in caring for women labouring and giving birth in water (n = 24). Intervention: An online learning tool comprising six randomly ordered short video simulations of blood loss in a birthing pool in real time, and a tutorial giving verbal and pictorial guidance on making accurate blood loss estimations in water was developed then piloted. Midwives’ accuracy scores for estimating blood loss in each of the videos were calculated at three timepoints; pre and immediately post the learning component, and six weeks later. The estimated blood loss volume was subtracted from the actual blood loss volume, to give the difference between estimated and real blood loss in millilitres (ml) which was then converted to percentage difference to standardise comparison across the six volumes. The differences between pre- and post-learning for each of the six blood volumes was analysed using a repeated measures ANOVA. Statistical significance was set at p < 0.05. An online questionnaire incorporated questions using Likert scales to gauge confidence and competence and free text. Free text responses were analysed using a modified form of inductive content analysis. Findings: Twenty-two midwives completed the online learning and immediate post-test, 14 completed a post-test after six weeks, and 15 responded to the online questionnaire. Pre-test results showed under-estimation of all blood loss volumes and particularly for the two largest volumes (1000 and 1100 ml). Across all volumes, accuracy of estimation was significantly improved at post-test 1. Accuracy diminished slightly, but overall improvement remained, at post-test 2. Participants rated the online tool positively and made suggestions for refining it. Key conclusions and implications for practice: This is the first study measuring the accuracy of midwives’ blood loss estimations in a birthing pool using real-time simulations and testing the effectiveness of an online learning tool to improve this important skill. Our findings indicate a need to develop interventions to improve midwives’ accuracy at visually estimating blood loss in water, and the potential of an online approach. Most women who labour and/or give birth in water do so in midwifery-led settings without immediate access to medical support. Accuracy in blood loss estimations is an essential core skil

Incidence of and risk factors for perineal trauma: A prospective observational study

Background: Our aim was to describe the range of perineal trauma in women with a singleton vaginal birth and estimate the effect of maternal and obstetric characteristics on the incidence of perineal tears. Methods: We conducted a prospective observational study on all women with a planned singleton vaginal delivery between May and September 2006 in one obstetric unit, three freestanding midwifery-led units and home settings in South East England. Data on maternal and obstetric characteristics were collected prospectively and analysed using univariable and multivariable logistic regression. The outcome measures were incidence of perineal trauma, type of perineal trauma and whether it was sutured or not. Results: The proportion of women with an intact perineum at delivery was 9.6% (125/1,302) in nulliparae, and 31.2% (453/1,452) in multiparae, with a higher incidence in the community (freestanding midwifery-led units and home settings). Multivariable analysis showed multiparity (OR 0.52; 95% CI: 0.30-0.90) was associated with reduced odds of obstetric anal sphincter injuries (OASIS), whilst forceps (OR 4.43; 95% CI: 2.02-9.71), longer duration of second stage of labour (OR 1.49; 95% CI: 1.13-1.98), and heavier birthweight (OR 1.001; 95% CI: 1.001-1.001), were associated with increased odds. Adjusted ORs for spontaneous perineal truama were: multiparity (OR 0.42; 95% CI: 0.32-0.56); hospital delivery (OR 1.48; 95% CI: 1.01-2.17); forceps delivery (OR 2.61; 95% CI: 1.22-5.56); longer duration of second stage labour (OR 1.45; 95% CI: 1.28-1.63); and heavier birthweight (OR 1.001; 95% CI: 1.000-1.001). Conclusions: This large prospective study found no evidence for an association between many factors related to midwifery practice such as use of a birthing pool, digital perineal stretching in the second stage, hands off delivery technique, or maternal birth position with incidence of OASIS or spontaneous perineal trauma. We also found a low overall incidence of OASIS, and fewer second degree tears were sutured in the community than in the hospital settings. This study confirms previous findings of overall high incidence of perineal trauma following vaginal delivery, and a strong association between forceps delivery and perineal trauma. © 2013 Smith et al; licensee BioMed Central Ltd

Developing an initiative to involve service-users in the recruitment of student midwives

In this fourth article of our Advancing practice education series, a novel initiative regarding the engagement of service-users to student midwife recruitment is outlined. Whilst the NMC mandates service user involvement, it can be challenging to implement. We at Oxford Brookes University introduced an initiative involving group discussions between candidates and service users. Feedback was sought via an evaluation form which 68 candidates and six service users completed. Candidates enjoyed the opportunity to question mothers in an informal group setting, and women felt valued through sharing their stories and making a meaningful contribution to the recruitment process
