Abstract
This paper presents a novel, systematic way to understand the causes of cervical head entrapment in vaginal breech births, and new insights into management. Three different types of cervical head entrapment are described, with detailed illustrations: unpredictable and potentially catastrophic, manageable, and preventable. The first affects preterm and growth-restricted fetuses. The second involves some degree of uterine prolapse. The third may result from prolonged head entrapment at the pelvic inlet, leaving time for cervical contraction or oedematous entrapment. Traditional and innovative strategies to resolve and prevent this complication are described and illustrated, with suggestions for further research.

Barriers and facilitators for implementation of OptiBreech collaborative care: A qualitative study as part of an implementation process evaluation. Women Birth 2024; 37:101656.

Abstract
PROBLEM Lack of opportunity for breech training and clinical experience reduced professional confidence and expertise in supporting vaginal breech birth. BACKGROUND OptiBreech collaborative care is a care pathway for breech presentation at term that aims to enable improve safety through person-centred care and improved training opportunities for maternity professionals, within dedicated clinics and intrapartum support. In feasibility work, barriers and facilitators to team implementation were observed by team members. AIM This study sought to describe factors affecting optimal future implementation and safety of OptiBreech care. METHODS Semi-structured interviews were conducted with staff members at 13 OptiBreech trial sites (17 midwives and 4 obstetricians, n=21), via video conferencing software. The Theoretical Domains Framework (TDF) was used to identify factors impacting team implementation. Themes identified in the TDF were refined in reflexive discussion and grouped into key facilitators, key barriers, and dynamic factors (which span both barriers and facilitators). The interviews were then coded, analysed, and interpreted according to the refined framework. FINDINGS The key facilitators were broadly categorised within skill development, beliefs about capabilities, and social support from the wider multidisciplinary team. Key barrier categories were resources, social obstacles, and fears about consequences. Dynamic factor categories were individual responsibility, training, and attending births. CONCLUSION While some factors affecting implementation were specific to the individuals and cultures of certain Trusts, recommendations emerged from analysis that are more widely applicable across multiple settings. These should be considered going forward for future service implementation, and in the next stage of OptiBreech clinical trials.

Abstract
OptiBreech collaborative care is a multi-disciplinary care pathway for breech presentation at term, with continuity from a breech specialist midwife, including where chosen, for vaginal breech birth (VBB). Pilot randomised trial using unblinded 1:1 parallel group allocation to OptiBreech versus standard care, within a cohort. Participants were women with a breech-presenting fetus > 33 weeks, at four sites in England, January-June 2022. A two-stage consent process was used. Participants consented to undergo random selection to be offered a 'new care process', with a choice to accept it, or not. Primary objectives were to identify recruitment, acceptance, and attrition rates. Randomisation procedures and potential primary outcomes for a substantive study were also feasibility-tested. 68 women were randomised between January-June 2022. The consent process was acceptable to participants, but randomisation was unacceptable to women who specifically sought OptiBreech care. Two women withdrew due to concerns about sharing personal information. More women planned a VBB when randomised to OptiBreech Care (23.5% vs 0, p = .002, 95% CI = 9.3%,37.8%). Women randomised to OptiBreech care had: lower rates of cephalic presentation at birth (38.2% vs 54.5%), higher rates of vaginal birth (32.4% vs 24.2%), lower rates of in-labour caesarean birth (20.6% vs 36.4%), lower rates of neonatal intensive care (5.9% vs 9.1%), and lower rates of severe neonatal morbidity (2.9% vs 9.1%). Randomisation was stopped on the advice of the steering committee before the planned sample of 104, as lack of access to VBB within standard care prohibited comparison of outcomes. Demand for VBB is sufficient for a cohort study, but comparison of outcomes by 1:1 randomisation is not feasible. OptiBreech care would be best evaluated using stepped wedge cluster randomisation.

Abstract
BACKGROUND Attendance of skilled and experienced professionals at breech births has been associated with a reduction in adverse perinatal outcomes. We aimed to determine whether United Kingdom National Health Service (NHS) sites could reliably provide attendants with OptiBreech training and/or advanced proficiency (intervention feasibility) and consistent care (fidelity) that meets women's needs (acceptability), with low neonatal admission rates (safety) and recruitment adequate to support a clinical trial (trial feasibility). METHODS Mixed methods implementation evaluation was used. Settings were 13 services in England and Wales. Participants were 82 women requesting support for a vaginal breech birth (VBB) at term. Outcomes were descriptively analyzed. Twenty-one women were interviewed, and transcripts were analyzed using the Theoretical Framework of Acceptability. Iterative analysis informed subsequent interviews and the ongoing process of implementation across sites. RESULTS Although we initially suggested multidisciplinary teams, actively recruiting Trusts yielded services where VBB care was provided through a dedicated clinic, organized and delivered primarily by a lead midwife who functioned as a specialist. This model achieved 87.5% fidelity with the intervention's goal of ensuring the attendance of OptiBreech-trained professionals. Neonatal outcomes remained stable, with an admission rate of 5.5%. Women reported care from specialist midwives as highly acceptable, but the model is vulnerable without a strategic effort to develop additional proficient team members. CONCLUSIONS Dedicated clinics coordinated by specialist midwives appear to be an acceptable and feasible implementation strategy to test the safety and effectiveness of proficient team care for VBB in a clinical trial. Back-up arrangements should be maintained while additional members of the team develop proficiency.

The feasibility of team care for women seeking to plan a vaginal breech birth (OptiBreech 1): an observational implementation feasibility study in preparation for a pilot trial.

Abstract
BACKGROUND OptiBreech Care is a care pathway for breech presentation at term, including where chosen, physiological breech birth attended by professionals with advanced training and/or proficiency. We aimed to assess the feasibility of implementing OptiBreech team care prior to proceeding with a planned pilot randomised controlled trial. METHODS Our design was an observational implementation feasibility assessment across England and Wales, January 2021-June 2022. Our objectives were to determine whether Trusts could provide attendants with advanced training (implementation feasibility), who deliver protocol-consistent care (fidelity), within existing resources (costs), while maintaining low neonatal admission rates (safety) and adequate recruitment rates (trial feasibility). Participants included women > 37 weeks pregnant with a breech-presenting foetus, requesting support for a vaginal breech birth following standard counselling, and staff involved in the study. No randomisation occurred in this first stage of feasibility work. RESULTS Thirteen National Health Service sites were recruited. A total of 82 women planned births in the study. Sites with a breech specialist midwife recruited at double the rate of sites without (0.90/month, 95% CI 0.64-1.16 vs 0.40, 95% CI 0.12-0.68). Referrals into the study came from midwives (46%), obstetricians (34%) and women themselves (20%). Vaginal births were attended by staff with OptiBreech training at 87.5% (35/40, 95% CI 0.732-0.958) and by staff who met additional proficiency criteria at 67.5% (27/40, 95% CI 0.509-0.814). Fidelity criteria were more consistently met by staff who also met proficiency criteria. There were four neonatal admissions (4.9%, 4/82), including one serious adverse outcome (1.2%, 1/82). CONCLUSIONS A prospective observational cohort of OptiBreech collaborative care, which could potentially support nested or cluster randomisation, appears feasible in sites willing to establish a dedicated clinic and strategically develop further proficient members of staff, with back-up plans for supporting rapidly progressing births. Randomisation procedures remain to be feasibility tested. It is funded by the NIHR (NIHR300582).

Abstract
Background Guidelines for breech management at term emphasise choice and informed decision-making. Despite this, the choice of vaginal breech birth (VBB), is not always available or accessible. We aimed to describe the experiences of women seeking a VBB as reported in primary research and to offer strategies for improving this experience that are grounded in evidence. Methods We conducted a systematic review and qualitative meta-synthesis of the results, using grounded theory analysis methods (PROSPERO registration CRD42021262380), with literature published between January 2000 and February 2022. Seven databases were searched. Our review included literature about women with breech presentation, who sought a planned or unplanned VBB. Studies considering only experiences of alternative management (e.g. caesarean, external cephalic version), and those investigating healthcare workers' experiences were excluded. Covidence systematic review software was used for screening and quality assessment. Qualitative data were extracted using NVivo software (20.5.0). Data were analysed through an iterative process based on constant comparison methods, with an iterative and reflexive code generation process. Codes were then arranged into 'categories of experience', which gave rise to over-arching themes. Results Our review included 19 studies. We present one overarching theory: 'Women who wish to plan a vaginal breech birth seek connected autonomy'. Our schematic, depicting this theory, includes seven main categories of experience: paternalistic healthcare; emotional turmoil; judgement and self-doubt; mother vs society: refusing to conform; isolated but united by breech; welcomed direction; and supported self-determination and self-efficacy. Conclusions Women seeking to plan a VBB feel vulnerable and wish to connect with capable and confident healthcare providers. To meet their needs, services should be designed so that they can connect with clinicians who are willing and able to support their autonomy. Services should also seek to limit their exposure to disrespectful and judgemental interactions with healthcare providers.

Abstract
Background In high altitude areas, like Tibet, most fetuses in breech presentation at term are delivered vaginally owing to a variety of reasons, but this has not been published. Objective This study aimed to provide references and evidence for the delivery of breach presentation term fetuses in high altitude areas, through comparing and analyzing the data of full-term singleton fetuses with breech or cephalic presentation in Naqu People's Hospital, Tibet. Study design We retrospectively analyzed the clinical data of 451 breech presentation fetuses mentioned above over a period of 5 years (2016-2020). A total of 526 cephalic presentation fetuses' data within 3 months (1 June to 1 September 2020) of the same period were collected too. Statistics were compared and assembled on fetal mortality, Apgar scores, and severe neonatal complications for both planned cesarean section (CS) and vaginal delivery. In addition, we also analyzed the types of breech presentation, the second stage of labor, and damage to the maternal perineum during vaginal delivery. Results Among the 451 cases of breech presentation fetuses, 22 cases (4.9%) elected for CS and 429 cases (95.1%) elected for vaginal delivery. Of the women who chose vaginal trial labor, 17 cases underwent emergency CSs. The perinatal and neonatal mortality rate was 4.2% in the planned vaginal delivery group and the incidence of severe neonatal complications was 11.7% in the transvaginal group, no deaths were detected in the CS group. Among the 526 cephalic control groups with planned vaginal delivery, the perinatal and neonatal mortality was 1.5% (p = 0.012), and the incidence of severe neonatal complications was 1.9%. Among vaginal breech deliveries, most of them were complete breech presentation (61.17%). Among the 364 cases, the proportion of intact perinea was 45.1%, and first degree lacerations accounted for 40.7%. Conclusion In the Tibetan Plateau region, vaginal delivery was less safe than cephalic presentation fetuses for full-term breech presentation fetuses delivered in the lithotomy position. However, if dystocia or fetal distress can be identified in time and then encouraged to convert to cesarean, its safety will be greatly improved.

Abstract
Background Breech births are associated with a high rate of hypoxic injury, in part due to cord occlusion during emergence. Maximum time intervals and guidelines oriented toward earlier intervention have been proposed in a Physiological Breech Birth Algorithm. We wished to further test and refine the Algorithm for use in a clinical trial. Methods We conducted a retrospective case-control study in a London teaching hospital, including 15 cases and 30 controls, during the period of April 2012 to April 2020. Our sample size was powered to test the hypothesis that exceeding recommended time limits is associated with neonatal admission or death. Data collected from intrapartum care records was analysed using SPSS v26 statistical software. Variables were intervals between the stages of labour and various stages of emergence (presenting part, buttocks, pelvis, arms, head). The chi-square test and odds ratios were used to determine association between exposure to the variables of interest and composite outcome. Multiple logistic regression was used to test the predictive value of delays defined as non-adherence the Algorithm. Results Logistic regression modelling using the Algorithm time frames had an 86.8% accuracy, a sensitivity of 66.7% and a specificity of 92.3% for predicting the primary outcome. Delays between umbilicus and head >3 minutes (OR: 9.508 [95% CI: 1.390-65.046] p=0.022) and from buttocks on the perineum to head >7 minutes (OR: 6.682 [95% CI: 0.940-41.990] p=0.058) showed the most effect. Lengths of time until the first intervention were consistently longer among the cases. Delay in intervention was more common among cases than head or arm entrapment. Conclusion Emergence taking longer than the limits recommended in the Physiological Breech Birth algorithm may be predictive of adverse outcomes. Some of this delay is potentially avoidable. Improved recognition of the boundaries of normality in vaginal breech births may help improve outcomes.
