Impact of collegial midwifery assistance during second stage of labour on women's experience: a follow-up from the Swedish Oneplus randomised controlled trial.

OBJECTIVE: To compare experiences of the second stage of labour in women randomised to assistance by one or by two midwives to reduce severe perineal trauma (SPT). DESIGN: Analysis of a secondary outcome within the Swedish Oneplus multicentre randomised trial. SETTING: Five obstetric units in Sweden between December 2018 and March 2020. PARTICIPANTS: Inclusion criteria in the Oneplus trial were women opting for their first vaginal birth from gestational week 37+0 with a singleton pregnancy and a live fetus in the vertex presentation. Further inclusion criteria were language proficiency in Swedish, English, Arabic or Farsi. Exclusion criteria were multiple pregnancies, intrauterine fetal demise and planned caesarean section. Of the 3059 women who had a spontaneous vaginal birth, 2831 women had consented to participate in the follow-up questionnaire. INTERVENTIONS: Women were randomly assigned (1:1) to assistance by two midwives (intervention group) or one midwife (standard care) when reaching the second stage of labour. OUTCOME MEASURES: Data were analysed by intention to treat. Comparisons between intervention and standard care regarding experiences of the second stage of labour were evaluated with items rated on Likert scales. The Student's t-test was used to calculate mean differences with 95% CIs. RESULTS: In total 2221 (78.5%) women responded to the questionnaire. There were no statistically significant differences regarding women's experiences of being in control, feelings of vulnerability or pain. Women randomised to be assisted by two midwives agreed to a lesser extent that they could handle the situation during the second stage (mean 3.18 vs 3.26, 95% CI 0.01 to 0.15). Conducted subgroup analyses revealed that this result originated from one of the study sites. CONCLUSIONS: The intervention's lack of impact on the experience of the second stage is of importance considering the reduction in SPT when being assisted by two midwives. TRIAL REGISTRATION NUMBER: NCT03770962.

Midwives' experiences of professional learning when practicing collegial midwifery assistance during the active second stage of labour: data from the oneplus trial.

BACKGROUND: Learning is a lifelong process and the workplace is an essential arena for professional learning. Workplace learning is particularly relevant for midwives as essential knowledge and skills are gained through clinical work. A clinical practice known as 'Collegial Midwifery Assistance' (CMA), which involves two midwives being present during the active second stage of labour, was found to reduce severe perineal trauma by 30% in the Oneplus trial. Research regarding learning associated with CMA, however, is lacking. The aim was to investigate learning experiences of primary and second midwives with varying levels of work experience when practicing CMA, and to further explore possible factors that influence their learning. METHODS: The study uses an observational design to analyse data from the Oneplus trial. Descriptive statistics and proportions were calculated with 95% confidence intervals. Stratified univariable and multivariable logistic regression analysis were performed. RESULTS: A total of 1430 births performed with CMA were included in the study. Less experienced primary midwives reported professional learning to a higher degree (< 2 years, 76%) than the more experienced (> 20 years, 22%). A similar but less pronounced pattern was seen for the second midwives. Duration of the intervention ≥ 15 min improved learning across groups, especially for the least experienced primary midwives. The colleague's level of experience was found to be of importance for primary midwives with less than five years' work experience, whereas for second midwives it was also important in their mid to late career. Reciprocal feedback had more impact on learning for the primary midwife than the second midwife. CONCLUSIONS: The study provides evidence that CMA has the potential to contribute with professional learning both for primary and second midwives, for all levels of work experience. We found that factors such as the colleague's work experience, the duration of CMA and reciprocal feedback influenced learning, but the importance of these factors were different for the primary and second midwife and varied depending on the level of work experience. The findings may have implications for future implementation of CMA and can be used to guide the practice.

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.

Primary midwives' experiences of collegial midwifery assistance during the active second stage of labor: Data from the Oneplus trial.

BACKGROUND: Collegial midwifery assistance during the active second stage of labor that involves a second midwife being present has been shown to reduce severe perineal trauma (SPT) by 30%. The aim of this study was to investigate primary midwives' experiences of collegial midwifery assistance with the purpose of preventing SPT during the active second stage of labor. METHODS: This study uses an observational design with data from a multicenter randomized controlled trial (Oneplus). Data consist of clinical registration forms completed by the midwives after birth. Descriptive statistics as well as univariable and multivariable logistic regression were used to analyze the data. RESULTS: The majority of the primary midwives felt confident (61%) and were positive (56%) toward the practice. Midwives with less than 2 years' work experience were more likely to completely agree they felt confident (aOR 9.18, 95% CI: 6.28-13.41) and experience the intervention as positive (aOR 4.04, 95% CI: 2.83-5.78) than those with over 20 years' work experience. Factors such as duration of time spent in the birthing room by the second midwife, opportunity for planning and if the second midwife provided support were further associated with the primary midwife's experience of the practice as being positive. CONCLUSIONS: Our findings indicate that having a second midwife present during the active second stage of labor was an accepted practice, with the majority of primary midwives feeling confident and positive toward the intervention. This was especially pronounced among midwives with less than 2 years' work experience.

Swedish midwives' experiences of collegial midwifery assistance during the second stage of labour: A qualitative study.

BACKGROUND: There has been an increased focus on clinical practice that may reduce severe perineal trauma due to awareness of the associated morbidity. Knowledge regarding the best practice to reduce these injuries is limited. Collegial midwifery assistance during the second stage of labour that involves an additional midwife being present has recently been implemented into many Swedish birth units with the aim of reducing severe perineal trauma. However, no studies have been conducted to evaluate midwives' experiences and views of this practice. AIM: The aim of this study was to explore midwives' experiences of collegial midwifery assistance during the second stage of labour. METHODS: A qualitative study was undertaken with five focus groups conducted with 37 midwives who were part of a multisite randomised controlled trial. The data was analysed with reflexive thematic analysis. FINDINGS: Four key themes were generated: (i) "challenging the professional role"; (ii) "a balancing act between different roles"; (iii) "not just why and how - but who"; (iv) "a potential arena for learning". CONCLUSION: This practice enabled valuable collegial support and learning. The midwives' experiences were multifaceted and influenced by several factors, including norms and culture in the birth units as well as personal relationships and the midwives' views on their role and childbirth. Staffing should be adapted in clinical practice to optimise the conditions for collegial support and learning while avoiding unintended consequences.

The effect of two midwives during the second stage of labour to reduce severe perineal trauma (Oneplus): a multicentre, randomised controlled trial in Sweden.

BACKGROUND: Severe perineal trauma (SPT) affecting the anal sphincter muscle complex is a serious complication following childbirth, associated with short-term and long-term maternal morbidity. Effective preventive strategies are still scarce. The aim of the Oneplus trial was to test the hypothesis that the presence of a second midwife during the second stage of labour, with the purpose of preventing SPT, would result in fewer injuries affecting the anal sphincter than if attended by one midwife. METHODS: In this multicentre, randomised, controlled parallel group, unmasked trial done at five obstetric units in Sweden, women were randomly assigned to be assisted by either one or two midwives in late second stage. Nulliparous women and women planning the first vaginal birth after caesarean section who were age 18-47 years were randomly assigned to an intervention when reaching the second stage of labour. Further inclusion criteria were gestational week 37+0, carrying a singleton live fetus in vertex presentation, and proficiency in either Swedish, English, Arabic, or Farsi. Exclusion criteria were a multiple pregnancy, intrauterine fetal demise, a planned caesarean section, or women who were less than 37 weeks pregnant. Randomisation to the intervention group of two midwives or standard care group of one midwife (1:1) was done using a computer-based program and treatment groups were allocated by use of sealed opaque envelopes. All women and midwives were aware of the group assignment, but the statistician from Clinical Studies Forum South, who did the analyses, was masked to group assignment. Midwives were instructed to implement existing prevention models and the second midwife was to assist on instruction of the primary midwife, when asked. Midwives were also instructed to complete case report forms detailing assistance techniques and perineal trauma prevention techniques. The primary outcome was the proportion of women who had SPT, for which odds ratios (ORs) and 95% CIs were calculated, and logistic regression was done to adjust for study site. All analyses were done according to intention to treat. The trial is registered with ClinicalTrials.gov, NCT0377096. FINDINGS: Between Dec 10, 2018, and March 21, 2020, 8866 women were assessed for eligibility, and 4264 met the inclusion criteria and agreed to participate. 3776 (88·5%) of 4264 women were randomly assigned to an intervention after reaching the second stage of labour. 1892 women were assigned to collegial assistance (two midwives) during the second stage of labour and 1884 women were assigned to standard care (one midwife). 13 women in each group did not meet the inclusion criteria and were excluded. After further exclusions, 1546 women spontaneously gave birth in the intervention group and 1513 in the standard care group. 1546 women in the intervention group and 1513 in the standard care group were included in the intention-to-treat analysis of the primary outcome. There was a significant reduction in SPT in the intervention group (3·9% [61 of 1546] vs 5·7% [86 of 1513]; adjusted OR 0·69 (0·49-0·97). INTERPRETATION: The presence of two midwives during the active second stage can reduce SPT in women giving birth for the first time.
