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.

Comparison of diagnostic criteria for significant anal sphincter defects between endoanal and transperineal ultrasound

OBJECTIVE

To evaluate the agreement between three-dimensional endoanal ultrasound (EAUS) and four-dimensional transperineal ultrasound (TPUS) in measuring anal sphincter defect angle.

METHODS

This was a secondary analysis of the PERINEAL study, which evaluated the effect of perineal wound infection on anal sphincter integrity. Women were reviewed once a week, until their perineal wound had healed or for up to a maximum of 16 weeks. At each visit, both EAUS and TPUS (the latter at rest and on maximum pelvic floor muscle contraction (PFMC)) were performed to evaluate the presence of external (EAS) and internal (IAS) anal sphincter defect and measure the defect size. The largest angle size of a defect at the same sphincter level was analyzed. A defect was deemed significant if it was > 30°. Kappa coefficient (κ), intraclass correlation coefficient and standard error of measurement (SEM) were calculated, using EAUS as the reference standard.

RESULTS

In 73 women scanned at weekly intervals, a total of 250 EAUS and 250 TPUS scans were performed. An EAS defect was found in 55 (22.0%) EAUS images and 47 (18.8%) TPUS images. An IAS defect was found in 26 (10.4%) images on both modalities. There was excellent agreement (κ = 0.87) between TPUS and EAUS in diagnosing the presence of an EAS defect and perfect agreement (κ = 1.00) in diagnosing the presence of an IAS defect. TPUS performed at rest had poor and moderate agreement with EAUS in measuring EAS and IAS defect size, respectively, with respective SEMs of ± 16.1° and ± 27.9°. TPUS performed during maximum PFMC had poor and moderate agreement with EAUS in measuring EAS and IAS defect size, respectively, with respective SEMs of ± 16.5° and ± 26.4°. Based on the SEMs, if the diagnostic cut-off of 30° for defect size on TPUS was used, an incorrect diagnosis of significant EAS defect could occur in approximately 9-36% of women and an incorrect diagnosis of a significant IAS defect could occur in approximately 4-15% of women, using EAUS as the reference.

CONCLUSIONS

This is the first study to compare directly anal sphincter defect angle measurements obtained on EAUS and TPUS. A cut-off angle of 30° should not be used for the diagnosis of a significant residual anal sphincter defect during TPUS examination. Further research is required to determine the optimal defect cut-off angle for TPUS. © 2022 The Authors.

Severe perineal trauma among women undergoing vaginal birth after cesarean delivery: A population-based cohort study

BACKGROUND

To examine risk of severe perineal trauma among nulliparous women and those undergoing vaginal birth after cesarean delivery (VBAC).

METHODS

This is a population-based cohort study of all births to women with their two first consecutive singleton pregnancies in Stockholm-Gotland Sweden between 2008 and 2014. Risk of severe perineal trauma was compared between nulliparous women and those undergoing VBAC with severe perineal trauma being the main outcome measure. Associations between indication and timing of primary cesarean delivery and risk of severe perineal trauma in subsequent vaginal birth were analyzed using Poisson regression analysis.

RESULTS

The rate of severe perineal trauma among nulliparous women and those undergoing VBAC was 7.0% and 12.3%, respectively. Compared with nulliparous women, those undergoing VBAC were significantly older, had a shorter stature, and gave birth in a non-upright position to heavier infants with larger head circumferences. The rate of instrumental vaginal delivery among nulliparous women and those undergoing VBAC was 19.3% and 20.2%, respectively (P = 0.331). An increased risk of severe perineal trauma remained after adjustments among those undergoing VBAC (adjusted risk ratio 1.42, 95% CI 1.23-1.63). Level of risk was not associated with indication (dystocia or signs of fetal distress) of primary cesarean delivery, nor how far the woman had progressed in labor (fully dilated versus planned cesarean delivery) before delivering by cesarean.

CONCLUSIONS

Compared with nulliparous women, those undergoing VBAC are at increased risk of severe perineal trauma, irrespective of indication and timing of primary cesarean delivery.

A systematic mixed studies review of women's experiences of perineal trauma sustained during childbirth

AIM

To explore the quantitative/qualitative literature on women's experiences of perineal trauma sustained during childbirth and the impact it may have on psychological/emotional wellbeing BACKGROUND: Obstetric complications during childbirth can be a risk factor for postpartum psychological distress. Perineal trauma is one of the most frequent obstetric complications and it is important to understand any impact on psychological/emotional wellbeing.

DESIGN

A convergent qualitative design using a hybrid deductive-inductive thematic synthesis approach to data transformation was used.

DATA SOURCES

Web of knowledge, CINAHL, MEDLINE, AMED, PsyArticles, PsycInfo until May 2017.

REVIEW METHODS

Stage 1: transforming findings from the qualitative, quantitative and mixed methods studies into themes using thematic synthesis. Stage 2: integrating themes from the quantitative studies into those derived from the qualitative studies RESULTS: Records (N=2152) found of which 11 qualitative 22 quantitative and 1 mixed methods were included in this review. Five themes were derived from thematic synthesis of qualitative studies 'The mystery of perineal trauma', 'The misery of perineal suturing', 'The postnatal perineum', 'Normalisation and feeling dismissed' and 'Adjusting to a new normal - Coping and compromise' and five themes identified from the quantitative studies, experience of birth (N=4), Sexual functioning (N=12), Social functioning (N=2), Psychological health (N=8) and Quality of Life (N=5).

CONCLUSION

Perineal trauma can have a negative impact on psychological/emotional wellbeing, however the literature is conflicted and in need of clarification. Future research should clearly describe the perineal status of the women in the sample, use validated measures and consider the timing of such measures. This article is protected by copyright.

Autoethnography and severe perineal trauma--an unexpected journey from disembodiment to embodiment

BACKGROUND

There is a lack of research reporting on the physical and emotional experiences of women who sustain severe perineal trauma (third and fourth degree tears). When the researcher identifies with the group being researched, autoethnography can allow an insight into the experiences of the marginalised group through the telling of a personal story. The aim of this paper is to share the journey travelled by an autoethnographer who on examining the issue of severe perineal trauma came to understand the challenges and rewards she experienced through this reflective and analytic process.

METHODS

A transformative emancipatory approach guided the design, data collection and analysis of findings from this study. For this paper, a multivocal narrative approach was taken in presenting the findings, which incorporated the words of both the autoethnographer and the twelve women who were interviewed as a component of the study, all of whom had sustained severe perineal trauma.

RESULTS

As an autoethnographer, being a member of the group being researched, can be confronting as the necessary reflection upon one's personal journey may lead to feelings of vulnerability, sadness, and emotional pain. The transformation from disembodied to embodied self, resulted in a physical and emotional breakdown that occurred for this autoethnographer.

CONCLUSION

Autoethnographers may experience unexpected emotional and physical challenges as they reflect upon their experiences and research the experiences of others. When incorporating a transformative emancipatory framework, the hardships are somewhat balanced by the rewards of witnessing 'self-transformation' as a result of the research.

"A patchwork of services"--caring for women who sustain severe perineal trauma in New South Wales--from the perspective of women and midwives

BACKGROUND

Current research into severe perineal trauma (3rd and 4th degree) focuses upon identification of risk factors, preventative practices and methods of repair, with little focus on women's experiences of, and interactions with, health professionals following severe perineal trauma (SPT). The aim of this study is to describe current health services provided to women in New South Wales (NSW) who have experienced SPT from the perspective of Clinical Midwifery Consultants (CMC) and women.

METHODS

This study used a descriptive qualitative design and reports on the findings of a component of a larger mixed methods study. Data were collected through a semi-structured discussion group using a variety of non-directive, open-ended questions leading CMCs of NSW. A survey was distributed prior to the discussion group to collect further information and enable a more comprehensive understanding of services provided. Data from individual interviews with twelve women who had experienced SPT during vaginal birth is used to provide greater insight into their interactions with, and ease of access to, health service providers in NSW. An integrative approach was undertaken in reporting the findings which involved comparing and analysing findings from the three sets of data.

RESULTS

One overarching theme was identified: A Patchwork of Policy and Process which identified that current health services operate in a 'patchwork' manner when caring for women who sustain SPT. They are characterised by lack of consistency in practice and standardisation of care. Within the overarching theme, four subthemes were identified: Falling through the gaps; Qualifications, skills and attitudes of health professionals; Caring for women who have sustained SPT; and Gold standard care: how would it look?

CONCLUSION

The findings from this study suggest that current health services in NSW represent a 'patchwork' of service provision for women who have sustained SPT. It appeared that women seek compassionate and supportive care based upon a clear exchange of information, and this should be considered when reflecting upon health service design. This study highlights the benefits of establishing multi-disciplinary collaborative specialist clinics to support women who experience SPT and associated morbidities, with the aim of providing comprehensive physiological and psychological support.

Risk of recurrence, subsequent mode of birth and morbidity for women who experienced severe perineal trauma in a first birth in New South Wales between 2000-2008: a population based data linkage study

BACKGROUND

Severe perineal trauma occurs in 0.5-10% of vaginal births and can result in significant morbidity including pain, dyspareunia and faecal incontinence. The aim of this study is to determine the risk of recurrence, subsequent mode of birth and morbidity for women who experienced severe perineal trauma during their first birth in New South Wales (NSW) between 2000 - 2008.

METHOD

All singleton births recorded in the NSW Midwives Data Collection between 2000-2008 (n=510,006) linked to Admitted Patient Data were analysed. Determination of morbidity was based upon readmission to hospital within a 12 month time period following birth for a surgical procedure falling within four categories: 1. Vaginal repair, 2. Fistula repair, 3. Faecal and urinary incontinence repair, and 4. Rectal/anal repair. Women who experienced severe perineal trauma during their first birth were compared to women who did not.

RESULTS

2,784 (1.6%) primiparous women experienced severe perineal trauma during this period. Primiparous women experiencing severe perineal trauma were less likely to have a subsequent birth (56% vs 53%) compared to those not who did not (OR 0.9; CI 0.81-0.99), however there was no difference in the subsequent rate of elective caesarean section (OR 1.2; 0.95-1.54), vaginal birth (including instrumental birth) (OR 1.0; CI 0.81-1.17) or normal vaginal birth (excluding instrumental birth) (OR 1.0; CI 0.85-1.17). Women were no more likely to have a severe perineal tear in the second birth if they experienced this in the first (OR 0.9; CI 0.67-1.34). Women who had a severe perineal tear in their first birth were significantly more likely to have an 'associated surgical procedure' within the ≤12 months following birth (vaginal repair following primary repair, rectal/anal repair following primary repair, fistula repair and urinary/faecal incontinence repair) (OR 7.6; CI 6.21-9.22). Women who gave birth in a private hospital compared to a public hospital were more likely to have an 'associated surgical procedure' in the 12 months following the birth (OR 1.8; CI 1.54-1.97), regardless of parity, birth type and perineal status.

CONCLUSION

Primiparous women who experience severe perineal trauma are less likely to have a subsequent baby, more likely to have a related surgical procedure in the 12 months following the birth and no more likely to have an operative birth or another severe perineal tear in a subsequent birth. Women giving birth in a private hospital are more likely to have an associated surgical procedure in the 12 months following birth.
