Women's experiences of being assisted by two midwives during the active second stage of labour: Secondary outcomes from the Oneplus trial.

BACKGROUND:'Collegial Midwifery Assistance' (CMA) is a clinical practice aiming to reduce severe perineal trauma (SPT) during childbirth. This practice involves two midwives being present during the active second stage of labour rather than one, which is the case in standard care. The effectiveness of CMA was evaluated in the Oneplus trial and a 30% reduction in SPT was shown. AIM:The aim was to investigate the experience of women who received the CMA intervention in the trial and to explore factors influencing their experiences. METHODS:A cohort study using data from the Oneplus trial and a one-month postpartum follow-up questionnaire. Descriptive statistics, univariable and multivariable logistic regression analyses were performed. RESULTS:A total of 1050 women who received the CMA intervention responded to the questionnaire. Of these, 35.8% reported that they strongly agreed with feeling safe during the second stage of labour and 42.6% were inclined to have an additional midwife present at a subsequent birth. The intervention was favourably received by women who experienced fear of birth, who were non-native Swedish speakers, and had lower educational attainment. Furthermore, women were more positive towards CMA the longer the intervention lasted. CONCLUSIONS:The results of this study suggest that the CMA intervention is accepted well by women and can be safely implemented into standard care. The duration of the CMA intervention was an important factor that influenced women's experiences and should be used to guide future practice.
