Pelvic + Anatomy: A new interactive pelvic anatomy model. Prospective randomized control trial with first-year midwife residents.

Detailed knowledge of female pelvic floor anatomy is essential for midwifery and other professionals in obstetrics. Physical models have shown great potential for teaching anatomy and enhancing surgical skills. In this article, we introduce an innovative physical anatomy model called "Pelvic+" to teach anatomical relationships in the female pelvis. The Pelvic+ model's value was compared to a traditional lecture in 61 first-year midwifery students randomly allocated to either the Pelvic+ (n = 30) or a control group (n = 32). The primary outcome measure was a quiz comprised of 15 multiple choice questions on pelvic anatomy. Participants were assessed at baseline (Pre-Test), upon completion of the intervention (Post-Test1) and 4 months afterward (Post-Test2). Satisfaction with the approach was assessed at Post-Test1. Increase in knowledge was greater and the approach more accepted among resident midwives when Pelvic+ was used instead of standard lectures. Four months after the intervention, the improvement in knowledge was preserved in the Pelvic+ group. This randomized study demonstrates that the Pelvic+ simulator is more effective than classical learning for pelvic anatomy education, and offers a higher level of satisfaction among students during the educational process. Medical students training in obstetrics and gynecology, or any professional who specializes in the female pelvic floor might also benefit from incorporation of the Pelvic+ model into their training program.

Informed consent in episiotomy: Co-analysis with midwives and distillation of best practice.

BACKGROUND: Performing an episiotomy where clinically indicated is a key intervention in the Obstetric Anal Sphincter Injury Care Bundle (OASI-CB) implemented across England and Wales to reduce the risk and increase the detection of severe perineal trauma after birth. Standards of consent provided to people in maternity care generally and for episiotomy specifically have been reported as suboptimal. Compromising birthing people's personal autonomy or sense of control has been linked to a dissatisfying birth experience, negative psychological sequelae, and litigation. METHODS: This study explored experienced midwives' practice of informed consent for episiotomy during a midwife-led birth. We sampled 43 midwives across eight NHS Trusts in England and Wales using online focus groups and telephone interviews about their experience of consent in episiotomy. Using qualitative content analysis and art-based co-analysis methods with eight midwives from across the research sites, we co-analyzed and co-constructed three themes and four practice recommendations from the data. RESULTS: Three themes were constructed from the data: Assent rather than consent, Change in culture to support best practice, and Standardized information. These themes informed the shaping of four recommendations for best practice in episiotomy informed consent. CONCLUSION: This study has shown how variations in midwifery practice and culture may impact birthing people's experience of informed consent in episiotomy. Midwives may not have the knowledge or skills to conduct a detailed consent conversation, leading to variation in practice and messages for birthing people. The use of antenatal discussion aids can offer women the opportunity to become informed and fully participate in the decision-making process.

Red flags for episiotomy in a midwife-led birth: Using co-production with midwives to capture clinical experience.

BACKGROUND: One of four key points in the Obstetric Anal Sphincter Injury Care Bundle, first piloted in the UK in 2016, was the directive to perform episiotomy when clinically indicated. Midwives are the primary health care professional for straightforward births in the UK and there is very little published literature that relates to their practice in this area. AIM: The aim of the study was to explore experienced midwives' decision-making processes in their assessments for episiotomy during birth. METHODS: 43 midwives self-identifying as confident in performing episiotomy were sampled across 8 NHS Trusts in England and Wales. Data collection was via online focus groups and 1:1 interviews. Primary thematic analysis was undertaken by the research team. Preliminary themes were used to structure a co-production analysis workshop where eight experienced midwives undertook a secondary analysis of the data resulting in four overall themes. FINDINGS: Four themes were identified, 'Optimising Perineal Function', 'Red Flags to Stimulate Decision-Making', 'The Midwives' Episiotomy' and 'Infiltration as a Catalyst for Birth'. DISCUSSION: Midwives use a number of visual, auditory and touch cues to inform their assessments for episiotomy during birth. CONCLUSION: This study provides valuable insight into the cues that guide experienced midwives' decision-making in relation to episiotomy and contributes evidence related to performing episiotomy when clinically indicated in spontaneous vaginal birth.

Evaluation of midwifery pelvic floor education and Training across the UK and Spain.

OBJECTIVES: The aim of this study was to evaluate current education and training of student and registered midwives across the UK and Spain; analysing both pelvic floor teaching and practical experience. STUDY DESIGN: A cross-sectional survey was carried out by 711 student and 384 registered midwives across different universities and regions in the UK and Spain. RESULTS: The vast majority (91.5 % n = 382) of UK students complete training without ever cutting or repairing an episiotomy. This compares to 39.4 % (n = 85) of registered midwives who did not cut an episiotomy during training. Only 20 % (n = 9) of Spanish and 10 % (n = 45) of UK registered midwives felt confident undertaking these techniques. In Spain just 15 % (n = 6) of students, compared to 54.8 % (n = 80) of registered midwives had received teaching on longer-term pelvic floor complications. CONCLUSION: There is a considerable deficit in the current training practices for midwives regarding episiotomies. This lack of practice and confidence may be impacting on the increased rates of perineal tears and pelvic dysfunction in post-partum women. Across registered midwives there are gaps in education regarding longer-term pelvic floor complications. Our study was limited by a smaller sample size from Spain compared to the UK. Our results show practical assessment of skills during training is desirable and could improve both the confidence and competence of midwives upon registration.

Postpartum perineal pain and dyspareunia related to each superficial perineal muscle injury: a cohort study.

OBJECTIVE: To assess the association between superficial perineal muscle trauma and perineal pain and dyspareunia. MATERIALS AND METHODS: Prospective cohort study of 405 women with a spontaneous vaginal birth comparing an intact perineum and first-degree perineal trauma group (n = 205) with a second-degree perineal trauma and episiotomy group (n = 200). Perineal pain was measured at 2 days, 10 days, 7 weeks, 3 months and 6 months postpartum. Dyspareunia was assessed at 7 weeks, 3 months and 6 months postpartum. RESULTS: All second-degree perineal traumas and episiotomies involved damage to the bulbospongiosus muscle (BSM), but not always to the superficial transverse perineal muscle (STPM). In case of second-degree trauma or episiotomy, the odds of pain at 10 days and dyspareunia at 6 months postpartum were four- and five-fold greater, respectively, than if the perineum had remained intact or suffered a first-degree perineal trauma [OR 4.4 (95% CI: 2.8-6.9) and OR 5.5 (95% CI: 2.8-10.9), respectively]. When comparing injuries where > 50% BSM ± STPM against those with < 50% BSM torn, pain was significantly higher at 10 days postpartum [OR 1.9 (95% CI: 1.1-3.6], with no difference at 7 weeks, while dyspareunia was significantly higher at 6 months postpartum [OR 3.3 (95% CI: 1.4-7.8)]. There was no difference in perineal pain or dyspareunia when comparing first-degree with < 50% BSM traumas. CONCLUSION: When perineal muscle trauma encompasses > 50% BSM ± STPM, perineal pain and dyspareunia persisted until 10 days and 6 months postpartum, respectively.

The impact of mode of subsequent birth after obstetric anal sphincter injury on bowel function and related quality of life: a cohort study.

INTRODUCTION AND HYPOTHESIS: The objective was to assess the impact of mode of subsequent birth on bowel function and related quality of life (QoL) in pregnant women with previous obstetric anal sphincter injury (OASI). METHODS: A prospective cohort study, designed, undertaken and reported using the Strengthening the Reporting of Observational Studies in Epidemiology statement and checklist. All pregnant women with previous OASI recruited at a specialist antenatal OASI clinic in a tertiary hospital to discuss mode of subsequent birth, between 1 January 2014 and 31 October 2015. Women are counselled in line with local guidelines based on Royal College of Obstetricians and Gynaecologists Green-top recommendations. In addition to routine endoanal ultrasound scan (EAUS), women recruited to the study were asked to complete the validated Manchester Health Questionnaire (MHQ) at both 34 weeks' gestation and 6 months postnatally. RESULTS: Of the 175 study participants, 125 (71.4%) completed follow-up at 6 months. There was no significant change in frequency of bowel symptoms or QoL domain scores in women who had a subsequent vaginal birth compared with caesarean section. Multivariate analysis showed the odds of having poor "incontinence impact" (OR 2.91, 95% CI 1.03-8.21) and "physical limitations" (OR 4.56, 95% CI 1.02-20.45) were significantly higher for women who had a subsequent caesarean section. CONCLUSIONS: For women with previous OASI, a subsequent vaginal birth is suitable for those with no bowel symptoms and normal EAUS and caesarean section is reasonable for women who do not have normal bowel function and/or normal EAUS findings; however, for some of these women bowel symptoms and QoL may be worsened.

Incidence of perineal pain and dyspareunia following spontaneous vaginal birth: a systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: Perineal pain and dyspareunia are experienced by women undergoing a vaginal birth that can have short and longer term physical and psychological morbidities. This review aimed to determine the incidence of perineal pain and dyspareunia following spontaneous vaginal birth (SVB) with intact perineum, first and second-degree perineal trauma or episiotomy. METHODS: Searches of MEDLINE, EMBASE, CINAHL, AMED and MIDIRS (inception - December 2017) were undertaken with selection criteria of any study evaluating the effect of intact perineum, first- or second-degree perineal trauma on perineal pain or dyspareunia in women with SVB. RESULTS: Eighteen studies (8 RCTs and 10 NRSs) were included. Fourteen and 12 studies were undertaken to assess perineal pain and dyspareunia after SVB, respectively. Meta-analysis of 16 studies (3133 women) demonstrated that women at 2 days postpartum experienced nearly the same incidence of perineal pain whether perineal trauma existed or not. At 4-10 days postpartum there was a significant reduction in the incidence of perineal pain for both presence and absence of any perineal trauma. Episiotomy was associated with the highest rate of perineal pain. The incidence of dyspareunia was high at resumption of sexual intercourse following SVB with an intact perineum. At 12 months, women still experienced dyspareunia whether perineal trauma existed or not. CONCLUSIONS: Women experience perineal pain and dyspareunia regardless of the presence or absence of perineal trauma after SVB; nonetheless, the reported incidence is higher if perineal trauma occurred.

Cuidado de las lesiones posparto en la consulta perineal / The role of a specialist clinic to care for childbirth related perineal trauma

El objetivo de este artículo fue revisar bibliográficamente los principales problemas que se derivan de las lesiones perineales, así como dar a conocer el trabajo de la matrona en una consulta perineal y el modo en que se está implementando esta consulta en el Hospital General de Granollers. Para cumplir con la primera parte del objetivo, se realizó una revisión bibliográfica sobre las complicaciones derivadas de las lesiones perineales que ocurren durante el parto. Los resultados obtenidos se han estructurado en los siguientes apartados: dolor perineal y dispareunia, infección y dehiscencia, incontinencia urinaria y prolapso genital (lesión del músculo elevador del ano) e incontinencia fecal y de gases (lesión del esfínter anal). En la segunda parte del artículo se explica la experiencia que se realizó en el Servicio de Obstetricia del Hospital de Granollers para disminuir la morbilidad posparto derivada de las lesiones perineales. Se implementaron diversas medidas de prevención, y se creó una consulta perineal para dar continuidad a los cuidados especializados para las mujeres que han sufrido alguna complicación perineal tras el parto vaginal. La matrona, integrada en el equipo multidisciplinario especialista en suelo pélvico, es la profesional que realiza este seguimiento y proporciona apoyo a la mujer

The objectives of this paper are twofold. Firstly, to review the morbidity associated with childbirth related perineal trauma (CRPT), and secondly, to outline the role of the Specialist Perineal Midwife and their integral role within a new Midwife-led Perineal Clinic in Hospital General de Granollers, Barcelona to care for women and reduce CRPT morbidity. The first part of this paper details the findings from a review of the literature on the CRPT morbidities of perineal pain and dyspareunia; perineal wound infection and breakdown; urinary incontinence and genital prolapse (levator ani muscle injury), and fecal incontinence (anal sphincter injury). The second part of this paper details the actions that have been implemented in the Obstetrics Service of the Hospital General de Granollers in order to reduce postpartum morbidity related to perineal injuries. These include the provision of a specialist perineal midwife who, through a dedicated perineal clinic, provides specialist care for women who suffer CRPT and is a core member of the perineal trauma/OASIS multi-disciplinary team

An obstetric sphincter injury risk identification system (OSIRIS): is this a clinically useful tool?

INTRODUCTION AND HYPOTHESIS: To establish the contribution of maternal, fetal and intrapartum factors to the risk of incidence of obstetric anal sphincter injuries (OASIS) and assess the feasibility of an OASIS risk prediction model based on variables available to clinicians prior to birth. METHODS: This was a population-based, retrospective cohort study using single-site data from the birth database of Aarhus University Hospital, Denmark. The participants were all women who had a singleton vaginal birth during the period 1989 to 2006. Univariate and multivariate logistic regression analyses were performed using multiple imputations for missing data and internally validated using bootstrap methods. The main outcome measures were the contributions of maternal, fetal and intrapartum events to the incidence of OASIS. RESULTS: A total of 71,469 women met the inclusion criteria, of whom 1,754 (2.45 %) sustained OASIS. In the multivariate analysis of variables known prior to birth, maternal age 20 - 30 years (OR 1.65, 95 % CI 1.44 - 1.89) and ≥30 years (OR 1.60, 95 % CI 1.39 - 1.85), occipitoposterior fetal position (OR 1.34, 95 % CI 1.06 - 1.70), induction/augmentation of labour (OR 1.46, 95 % CI 1.32 - 1.62), and suspected macrosomia (OR 2.20, 95 % CI 1.97 - 2.45) were independent significant predictors of OASIS, with increasing parity conferring a significant protective effect. The 'prebirth variable' model showed a 95 % sensitivity and a 24 % specificity in predicting OASIS with 1 % probability, and a 3 % sensitivity and a 99 % specificity in predicting OASIS with a 10 % probability. CONCLUSIONS: Our model identified several significant OASIS risk factors that are known prior to actual birth. The prognostic model shows potential for ruling out OASIS (high sensitivity with a low risk cut-off value), but is not useful for ruling in the event.

Impact of subsequent birth and delivery mode for women with previous OASIS: systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: Obstetric anal sphincter injuries (OASIS) are serious complications of vaginal birth. In a pregnancy following OASIS women may be keen to avoid an elective caesarean section, yet cautious about pursuing another vaginal birth that may result in further damage to the pelvic floor and possible long-term anal incontinence. This review aimed to evaluate the impact of subsequent birth and its mode on anal incontinence (AI) and/or quality of life (QoL), for women with previous OASIS. METHODS: Searches of MEDLINE, EMBASE, CINAHL, and AMED from inception to February 2016 were undertaken with selection criteria of any study evaluating the effect of a subsequent birth on AI and/or QoL in women with previous OASIS. Where possible, data were extracted to populate 2 × 2 tables and allow meta-analysis relating to the impact of subsequent birth on AI and/or QoL. RESULTS: Twenty-seven non-randomised studies were included. Meta-analysis of 14 studies (977 women) did not demonstrate any significant associations between AI in women with previous OASIS and subsequent birth or its mode. Impact on QoL was reported in 12 studies (912 women); however, difference in outcome reporting precluded data meta-analysis. CONCLUSIONS: Comparisons of outcomes and effective synthesis were limited by sample size, quality and heterogeneity of the studies included. Consequently, the optimal mode of delivery for women with previous OASIS is still not known and better data are needed.

Abdominal palpation to determine fetal position at labor onset: a test accuracy study.

OBJECTIVE: To examine the accuracy of abdominal palpation for identifying left-occipito-anterior (LOA) fetal position using abdominal ultrasound as the reference standard. DESIGN: Classical test accuracy study undertaken in 2005-2007. SETTING: Birmingham Women's Foundation NHS Trust serving a large, socio-economically and ethnically varied population. SAMPLE: All nulliparous women with spontaneous or induced labor before established labor (cervix <4cm dilated), with a singleton live pregnancy of over 37 completed gestational weeks without known fetal abnormalities. METHODS. Accuracy of abdominal palpation (index test) in identifying LOA fetal position, with abdominal ultrasound as reference. Trained observers blind to the index test results performed the ultrasound independently. MAIN OUTCOME MEASURES: Accuracy of palpation in determining LOA position. RESULTS: Midwives' abdominal palpation and ultrasound data were obtained from 629 women. There were 61 (9%) fetuses in LOA position that were verified by ultrasound. The sensitivity and specificity of palpation to detect LOA position were 34% (95%CI 23-46) and 71% (67-74), respectively. Midwives with experience >5 years achieved higher sensitivity compared to those with ≤5 years (odds ratio 4.02; 1.26-12.9; p=0.019). Sensitivity was higher for community compared with hospital midwives (OR 6.59; 1.11-39.11; p=0.038). CONCLUSIONS: Abdominal palpation to determine LOA position at the onset of labor had poor accuracy in nulliparous women on arrival at the maternity unit with a cervix dilation of <4cm. If future research demonstrates that an optimal fetal position at labor onset exists, ultrasound scan to confirm fetal position on arrival for birth may improve midwives' ability to prognosticate.
