Abstract
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 to test it in trial-within-a-cohort study.
Methods
Our design was a mixed methods trial 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), in a way acceptable to women and staff (acceptability), within existing resources (costs), while maintaining low neonatal admission rates (safety) and adequate recruitment rates (trial feasibility). Participants were women > 37 weeks pregnant with a breech-presenting fetus, requesting support for a vaginal breech birth following standard counselling, and the staff involved in the study. No randomisation occurred in this first stage of feasibility work.
Results
Thirteen National Health Service sites recruited. A total of 82 women planned births on the study, and 21 staff were interviewed. Sites with a breech specialist midwife and/or dedicated clinic recruited 1 woman/month, while sites without recruited an average of 2 women every 3 months. 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) and by staff who met stricter proficiency criteria at 67.5% (27/40). Fidelity criteria were met more consistently by staff who met proficiency criteria. There were four neonatal admissions (4.9%, 4/82), including one serious adverse outcome (1.2%, 1/82); these outcomes compare well with previous breech research. Women found the model of care highly acceptable compared to standard care, and staff providing care generally found the OptiBreech model acceptable. However, staffing shortages throughout the pandemic and persistent negative views of vaginal breech birth outside the teams created challenges.
Conclusions
A large prospective observational cohort of OptiBreech Care, which could potentially support nested or cluster randomisation, appears feasible in sites willing to establish a dedicated clinic and develop further proficient members of staff strategically, with back-up plans for supporting rapidly progressing births. Randomisation procedures remain to be feasibility-tested. Funded by the NIHR (300582).
