Optimal time intervals for vaginal breech births: a case-control study

Barriers and facilitators for implementation of OptiBreech collaborative care: A qualitative study as part of an implementation process evaluation

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.

Variations of cervical head entrapment in vaginal breech births: New insights on how to prevent, manage and resolve

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.

Breech specialist midwives and clinics in the OptiBreech Trial feasibility study: An implementation process evaluation

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.
