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.

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. Pilot Feasibility Stud 2023; 9:80. [PMID: 37173798 PMCID: PMC10175899 DOI: 10.1186/s40814-023-01299-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 04/10/2023] [Indexed: 05/15/2023] Open
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).
