Training and expertise in undertaking assisted vaginal delivery (AVD): a mixed methods systematic review of practitioners views and experiences.

Background: During childbirth, complications may arise which necessitate an expedited delivery of the fetus. One option is instrumental assistance (forceps or a vacuum-cup), which, if used with skill and sensitivity, can improve maternal/neonatal outcomes. This review aimed to understand the core competencies and expertise required for skilled use in AVD in conjunction with reviewing potential barriers and facilitators to gaining competency and expertise, from the point of view of maternity care practitioners, funders and policy makers. Methods: A mixed methods systematic review was undertaken in five databases. Inclusion criteria were primary studies reporting views, opinions, perspectives and experiences of the target group in relation to the expertise, training, behaviours and competencies required for optimal AVD, barriers and facilitators to achieving practitioner competencies, and to the implementation of appropriate training. Quality appraisal was carried out on included studies. A mixed-methods convergent synthesis was carried out, and the findings were subjected to GRADE-CERQual assessment of confidence. Results: 31 papers, reporting on 27 studies and published 1985–2020 were included. Studies included qualitative designs (3), mixed methods (3), and quantitative surveys (21). The majority (23) were from high-income countries, two from upper-middle income countries, one from a lower-income country: one survey included 111 low-middle countries. Confidence in the 10 statements of findings was mostly low, with one exception (moderate confidence). The review found that AVD competency comprises of inter-related skill sets including non-technical skills (e.g. behaviours), general clinical skills; and specific technical skills associated with particular instrument use. We found that practitioners needed and welcomed additional specific training, where a combination of teaching methods were used, to gain skills and confidence in this field. Clinical mentorship, and observing others confidently using the full range of instruments, was also required, and valued, to develop competency and expertise in AVD. However, concerns regarding poor outcomes and litigation were also raised. Conclusion: Access to specific AVD training, using a combination of teaching methods. Complements, but does not replace, close clinical mentorship from experts who are positive about AVD, and opportunities to practice emerging AVD skills with supportive supervision. Further research is required to ascertain effective modalities for wider training, education, and supportive supervision for optimal AVD use. Plain language summary: During the late stages of childbirth, complications can occur which require rapid birth of the baby. This can be facilitated with instruments (usually forceps or a suction cup) or by surgery (caesarean section). In some circumstances, instrumental birth (also termed assisted vaginal delivery, AVD) may be a better option than caesarean section. AVD requires practitioners to develop skills, competence and expertise in the procedure. Our aim for this review was to examine practitioners', funders' and policy makers' views about competence and expertise in AVD, how they can best gain this, the barriers and facilitators to implementing training packages, and their views, opinions and perspectives of their training. We included 27 studies (published 1985–2020), mostly from high-income countries. We had moderate confidence on one findings statement, with the rest assessed with low confidence. We found that practitioners valued extra training in AVD, observing others using the different instruments, and opportunities for clinical supervision, mentorship to gain experience, competence and expertise. We also found that, from the practitioners' perspective, competence encompasses a number of inter-related skill sets; non-technical skills (e.g. effective communication with the labouring woman), broad clinical skills (e.g. capacity to assess the whole clinical picture) and technical instrumental skills (e.g. correct application of a vacuum cup to the fetal head, or capacity to turn the baby so it is in the right position). Practitioners also identified a number of barriers and facilitators that supported (or did not support) their training needs and development. [ABSTRACT FROM AUTHOR]
