Associations between birth at, or after, 41 weeks gestation and perinatal encephalopathy: a cohort study
Background Preterm birth causes long-term problems, even for infants born 1 or 2 weeks early. However, less is known about infants born after their due date and over a quarter of infants are born over 1âweek late, and many still remain undelivered after 2âweeks. The aim of this work is to quantify the risks of infants developing encephalopathy when birth occurs after the due date, and if other proposed risk factors modify this relationship.
Methods The dataset contain information on 4 036 346 infants born in Sweden between 1973 and 2012. Exposure was defined as birth 7, or more, days after the infantsâ due date. The primary outcome was the development of neonatal encephalopathy (defined as seizures, encephalopathy or brain injury caused by asphyxia or with unspecified cause). Covariates were selected as presumed confounders a priori.
Results 28.4% infants were born 1 or more weeks after their due date. An infantâs risk of being born with encephalopathy was higher in the post 41 weeks group in the unadjusted (OR 1.40 (95% CI 1.32 to 1.49)) and final model (OR 1.38 (95% CI 1.29 to 1.47)), with the relative odds of encephalopathy increasing by an estimated 20% per week after the due date, and modified by maternal age (P=0.022).
Conclusions Singleton infants born at, or after, 41 weeks gestation have lower Apgar scores and higher risk of developing encephalopathy in the newborn period, and the association appeared more marked in older mothers. These data could be useful if provided to women as part of their decision-making
Impacted fetal head at caesarean section:a national survey of practice and training
This is a national survey of UK obstetric trainees and consultant labour ward leads designed to investigate the current practice and training for an impacted foetal head (IFH) at Caesarean Section (CS). An anonymous, on-line survey was disseminated to trainees via Postgraduate Schools and RCOG trainee representatives, and to labour ward leads via their national network. Three hundred and forty-five obstetric trainees and consultants responded. The results show that IFH is variably defined and encountered by most UK obstetricians (98% had encountered IFH and 76% had experienced it before full cervical dilatation). There is significant variation in management strategies, although most respondents would use a vaginal push up to assist delivery prior to reverse breech extraction. Responses revealed a paucity of training and lack of confidence in disimpaction techniques: over one in ten respondents had not received any training for IFH and less than half had received instruction in reverse breech extraction.Impact statement What is already known on the subject? IFH is an increasingly recognised, technically challenging complication of intrapartum CS. A recent report suggested that birth injuries associated with IFH are now as common as with shoulder dystocia. However, there is no consensus nor guidelines regarding the best practice for management or training. What do the results of this study add? This study demonstrates that IFH is poorly defined and commonly encountered by UK obstetricians. It highlights that IFH is not restricted to CS at full dilatation and reveals the ubiquity of the vaginal push method in UK practice. We found evidence that UK obstetricians are using techniques which have not been investigated and are not recommended for managing an IFH. Moreover, this survey is an eye-opener as to the paucity of training, highlighting that UK obstetric trainees are not adequately prepared to manage this emergency. What are the implications of these findings for clinical practice and/or further research? There is a pressing need to standardise the definition, guidance and training for IFH at CS. Further research should clarify the appropriate techniques for IFH and establish consensus for the best practice. An evidence-based simulation training package, which allows clinicians to learn and practice recognised disimpaction techniques is urgently required

IMproving the practice of intrapartum electronic fetal heart rate MOnitoring with cardiotocography for safer childbirth (the IMMO programme): protocol for a qualitative study.
INTRODUCTION: Suboptimal electronic fetal heart rate monitoring (EFM) in labour using cardiotocography (CTG) has been identified as one of the most common causes of avoidable harm in maternity care. Training staff is a frequently proposed solution to reduce harm. However, current approaches to training are heterogeneous in content and format, making it difficult to assess effectiveness. Technological solutions, such as digital decision support, have not yet demonstrated improved outcomes. Effective improvement strategies require in-depth understanding of the technical and social mechanisms underpinning the EFM process. The aim of this study is to advance current knowledge of the types of errors, hazards and failure modes in the process of classifying, interpreting and responding to CTG traces. This study is part of a broader research programme aimed at developing and testing an intervention to improve intrapartum EFM. METHODS AND ANALYSIS: The study is organised into two workstreams. First, we will conduct observations and interviews in three UK maternity units to gain an in-depth understanding of how intrapartum EFM is performed in routine clinical practice. Data analysis will combine the insights of an ethnographic approach (focused on the social norms and interactions, values and meanings that appear to be linked with the process of EFM) with a systems thinking approach (focused on modelling processes, actors and their interactions). Second, we will use risk analysis techniques to develop a framework of the errors, hazards and failure modes that affect intrapartum EFM. ETHICS AND DISSEMINATION: This study has been approved by the West Midlands-South Birmingham Research Ethics Committee, reference number: 18/WM/0292. Dissemination will take the form of academic articles in peer-reviewed journals and conferences, along with tailored communication with various stakeholders in maternity care

How to be a very safe maternity unit: An ethnographic study.
Maternity care continues to be associated with avoidable harm that can result in serious disability and profound anguish for women, their children, and their families, and in high costs for healthcare systems. As in other areas of healthcare, improvement efforts have typically focused either on implementing and evaluating specific interventions, or on identifying the contextual features that may be generative of safety (e.g. structures, processes, behaviour, practices, and values), but the dialogue between these two approaches has remained limited. In this article, we report a positive deviance case study of a high-performing UK maternity unit to examine how it achieved and sustained excellent safety outcomes. Based on 143âŻh of ethnographic observations in the maternity unit, 12 semi-structured interviews, and two focus groups with staff, we identified six mechanisms that appeared to be important for safety: collective competence; insistence on technical proficiency; monitoring, coordination, and distributed cognition; clearly articulated and constantly reinforced standards of practice, behaviour, and ethics; monitoring multiple sources of intelligence about the unit's state of safety; and a highly intentional approach to safety and improvement. These mechanisms were nurtured and sustained through both a specific intervention (known as the PROMPT programme) and, importantly, the unit's contextual features: intervention and context shaped each other in both direct and indirect ways. The mechanisms were also influenced by the unit's structural conditions, such as staffing levels and physical environment. This study enhances understanding of what makes a maternity unit safe, paving the way for better design of improvement approaches. It also advances the debate on quality and safety improvement by offering a theoretically and empirically grounded analysis of the interplay between interventions and context of implementation
Temporal trends in stillbirth over eight decades in England and Wales:A longitudinal analysis of over 56 million births and lives saved by improvements in maternity care
BACKGROUND: Considering the public health importance of stillbirth, this study quantified the trends in stillbirths over eight decades in England and Wales. METHODS: This longitudinal study utilized the publicly available aggregated data from the Office for National Statistics that captured maternity information for babies delivered in England and Wales from 1940 to 2019. We computed the trends in stillbirth with the associated incidence risk difference, incidence risk ratio, and extra lives saved per decade. RESULTS: From 1940-2019, 56â906â273 births were reported. The stillbirth rate declined (85%) drastically up to the early 1980s. In the initial five decades, the estimated number of deaths per decade further decreased by 67â765 (9.49/1000 births) in 1940-1949, 2569 (0.08/1000 births) in 1950-1959, 9121 (3.50/1000 births) in 1960-1969, 15â262 (2.31/1000 births) in 1970-1979, and 10â284 (1.57/1000 births) in 1980-1989. However, the stillbirth rate increased by an additional 3850 (0.58/1000 births) stillbirths in 1990-1999 and 693 (0.11/1000 births) stillbirths in 2000-2009. The stillbirth rate declined again during 2010-2019, with 3714 fewer stillbirths (0.54/1000 births). The incidence of maternal age 35 years) increased. CONCLUSIONS: The stillbirth rate declined drastically, but the rate of decline slowed in the last three decades. Though teenage pregnancy (<20 years) had reduced, the prevalence of women with a higher risk of stillbirth may have risen due to an increase in advanced maternal age. Improved, more personalised care is required to reduce the stillbirth rate further
Associations between early term and late/post term infants and development of epilepsy:A cohort study
Background While life-long impacts exist for infants born one or two weeks early little evidence exists for those infants born after their due date. However interventions could be used to expedite birth if the risks of continuing the pregnancy are higher than intervening. It is known that the risk of epilepsy in childhood is higher in infants exposed to perinatal compromise and therefore may be useful as a proxy for intrapartum compromise. The aim of this work is to quantify the likelihood of children developing epilepsy based on their gestational age at birth (37â39 weeks or â„41 weeks). Methods The work is based on term infants born in Sweden between 1983 and 1993 (n = 1,030,168), linked to data on disability pension, child mortality and in-patient epilepsy care. The reference group was defined as infants born at 39 or 40 completed weeks of gestation; compared with infants born at early term (37/38 weeks) or late/post term (41 weeks or more). Primary outcome was defined a-priori as a diagnosis of epilepsy before 20 years of age. Secondary outcomes were childhood mortality (before five years of age), and registered for disability pension before 20 years of age. Logistic regression models were used to assess any association of the outcomes with gestational age at birth. Findings In the unadjusted results, infants born 7 or more days after their due date had higher risks of epilepsy and disability pension than the reference group, but similar risks of child death. Early term infants showed higher risks of epilepsy, disability pension and child death. After adjustment for confounders, there remained a higher risk of epilepsy for both early term (OR 1·19 (1·11â1·29)) and late/post term infants (OR 1·13 (1·06â1·22)). Interpretation Infants born at 37/38 week or 41 weeks and above, when compared to those born at 39 or 40 weeks gestation, have an increased risk of developing epilepsy. This data could be useful in helping women and care givers make decisions with regard to the timing of induction of labour
