Episiotomy: Beliefs, practice and the impact of educational intervention

Facilitators and Barriers to Implementation of Perineal Techniques: A Scoping Review Applying the Consolidated Framework for Implementation Research

AIM

To summarise the barriers and facilitators to the clinical implementation of perineal techniques and to provide evidence-based insights for decision-making based on existing research.

DESIGN

A scoping review.

DATA SOURCES

Nine electronic databases (PubMed, Cochrane Library, Embase, CINAHL, ProQuest, CNKI, WanFang, VIP and SinoMed) were systematically searched on 4 February 2024.

REVIEW METHODS

This study followed Joanna Briggs Institute's scoping review methodology. The barriers and facilitators identified in the included studies were mapped to the domains of the Consolidated Framework for Implementation Research (CFIR): intervention characteristics, outer setting, inner setting, characteristics of individuals and process.

RESULTS

A total of 18 studies were finally included and analysed. The most frequently identified facilitator was theoretical education for midwives (inner setting). Common barriers included: lack of time to implement perineal techniques (intervention characteristics); labour pain and women's stress due to insufficient understanding of the birthing process, as well as women's reluctance to receive the perineal techniques (outer setting); risk factors for OASIS (inner setting); insufficient theoretical education for midwives and inadequate prenatal education for pregnant women (inner setting) and concerns about potential medical disputes among performers (characteristics of individuals).

CONCLUSIONS

Many of the factors influencing the implementation of perineal techniques identified in this review are modifiable. Developing implementation strategies based on these factors can promote the successful implementation of these perineal techniques in clinical settings.

IMPLICATIONS FOR THE PROFESSION

This scoping review could serve as a reference framework for health authorities in developing strategies to promote the use of perineal techniques in clinical practice.

IMPACT

Existing research has primarily focused on the outer setting, inner setting and characteristics of individuals implementing perineal techniques. Therefore, there is a need for more high-quality studies focusing on intervention characteristics and the implementation process.

REPORTING METHOD

This study followed the PRISMA extension for scoping reviews.

Episiotomy Practice and Its Associated Factors in Africa: A Systematic Review and Meta-Analysis

Background

Episiotomy, a surgical procedure that enlarges the vaginal opening during childbirth, was common practice until the early 2000s. Other sources, including the World Health Organization (WHO), advocate for the selective use of episiotomy. Episiotomy rates, on the other hand, have remained high in developing countries, while declining in developed countries. As a result, the current study sought to determine the overall prevalence of episiotomy in Africa as well as the risk factors associated with its practice.

Methods

Articles were searched in international electronic databases. A standardized Microsoft Excel spreadsheet and STATA software version 14 were used for data extraction and analysis, respectively. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist was used to write this report. A random-effects meta-analysis model was used to determine the pooled prevalence of episiotomy. A heterogeneity test was conducted using I-Squared (I²) statistics. Egger's test and funnel plots were conducted to detect publication bias. Subgroup analysis was also conducted. Association was expressed through a pooled odds ratio (OR) with a 95% Confidence Interval (CI).

Result

A total of 21 studies with 40,831 participants were included in the systematic review and meta-analysis. The pooled prevalence of episiotomy practice was 41.7% [95% CI (36.0–47.4), I² = 99.3%, P < 0.001). Primiparity [OR: 6.796 (95% CI (4.862–9.498)), P < 0.001, I²: 95.1%], medical doctors- assisted delivery [OR: 3.675 (95% CI (2.034–6.640)), P < 0.001, I²: 72.6%], prolonged second stage of labor [OR: 5.539 (95% CI (4.252–7.199)), P < 0.001, I²: 0.0%], using oxytocin [OR: 4.207 (95% CI (3.100–5.709)), P < 0.001, I²: 0.0%], instrument -assisted vaginal delivery [OR: 5.578 (95% CI (4.285–7.260)), P < 0.001, I²: 65.1%], and macrosomia [OR: 5.32 (95% CI (2.738–10.339)), P < 0.001, I²: 95.1%] were factors associated with episiotomy practice.

Conclusion

In this review, the prevalence of episiotomy among African parturients was high. A selective episiotomy practice should be implemented to reduce the high episiotomy rates.

Midwifery in Middle Eastern and North African countries: A scoping review

BACKGROUND

While midwives are positioned as critical providers for improving sexual, reproductive, maternal and newborn health outcomes in the Middle East and North African (MENA) countries, the standards of midwifery have not been explored systematically in this region.

AIM

The purpose of this scoping review was to provide an overview of existing literature on midwifery practice, education, and regulation in MENA countries in the context of ICM standards.

METHODS

A search was conducted inclusive of English and Persian written studies published between 2000 and 2019 in CINAHL plus; Ovid MEDLINE; PubMed; Scopus; and grey literature. Title and abstract and full-text review were performed in Covidence, and data extraction and synthesis performed using NVivo 12.

RESULTS

The initial search identified 7,994 articles. Overall, 139 studies were included in the review. Although, the primary concept of most included studies was "midwifery practice", "midwifery regulation" was addressed in limited way. Approximately 90% were from Middle Eastern countries. Forty-two per cent of studies used cross-sectional designs, and most originated from Iran, Jordan, and Palestine. Diversity was found in midwifery education, practice and regulation across the MENA countries. Midwives from different nations had uneven levels of proficiency, scope of practice, and education. Midwifery curricula were aligned with ICM competencies in some countries. Most countries had midwifery associations and were members of ICM. Some countries had regulations recognising midwifery as an autonomous profession.

CONCLUSION

Midwifery practice, education and regulation in MENA countries were not always comparable with ICM standards, although some progress was evident.

Understanding the perspectives and values of midwives, obstetricians and obstetric registrars regarding episiotomy: qualitative interview study

OBJECTIVES

Insight into perspectives and values of care providers on episiotomy can be a first step towards reducing variation in its use. We aimed to gain insight into these perspectives and values.

SETTING

Maternity care in the Netherlands.

PARTICIPANTS

Midwives, obstetricians and obstetric registrars working in primary, secondary or tertiary care, purposively sampled, based on their perceived episiotomy rate and/or region of work.

PRIMARY AND SECONDARY OUTCOME MEASURES

Perspectives and values of care providers which were explored using semistructured in-depth interviews.

RESULTS

The following four themes were identified, using the evidence-based practice-model of Satterfield et al as a framework: 'Care providers' vision on childbirth', 'Discrepancy between restrictive perspective and daily practice', 'Clinical expertise versus literature-based practice' and 'Involvement of women in the decision'. Perspectives, values and practices regarding episiotomy were strongly influenced by care providers' underlying visions on childbirth. Although care providers often emphasised the importance of restrictive episiotomy policy, a discrepancy was found between this vision and the large number of varying indications for episiotomy. Although on one hand care providers cited evidence to support their practice, on the other hand, many based their decision-making to a larger extent on clinical experience. Although most care providers considered women's autonomy to be important, at the moment of deciding on episiotomy, the involvement of women in the decision was perceived as minimal, and real informed consent generally did not take place, neither during labour, nor prenatally. Many care providers belittled episiotomy in their language.

CONCLUSIONS

Care providers' underlying vision on episiotomy and childbirth was an important contributor to the large variations in episiotomy usage. Their clinical expertise was a more important component in decision-making on episiotomy than the literature. Women were minimally involved in the decision for performing episiotomy. More research is required to achieve consensus on indications for episiotomy.

Birth-Related Perineal Trauma in Low- and Middle-Income Countries: A Systematic Review and Meta-analysis

Introduction Birth-related perineal trauma (BPT) is a common consequence of vaginal births. When poorly managed, BPT can result in increased morbidity and mortality due to infections, haemorrhage, and incontinence. This review aims to collect data on rates of BPT in low- and middle-income countries (LMICs), through a systematic review and meta-analysis. Methods The following databases were searched: Medline, Embase, Latin American and Caribbean Health Sciences Literature (LILACs), and the World Health Organization (WHO) regional databases, from 2004 to 2016. Cross-sectional data on the proportion of vaginal births that resulted in episiotomy, second degree tears or obstetric anal sphincter injuries (OASI) were extracted from studies carried out in LMICs by two independent reviewers. Estimates were meta-analysed using a random effects model; results were presented by type of BPT, parity, and mode of birth. Results Of the 1182 citations reviewed, 74 studies providing data on 334,054 births in 41 countries were included. Five studies reported outcomes of births in the community. In LMICs, the overall rates of BPT were 46% (95% CI 36–55%), 24% (95% CI 17–32%), and 1.4% (95% CI 1.2–1.7%) for episiotomies, second degree tears, and OASI, respectively. Studies were highly heterogeneous with respect to study design and population. The overall reporting quality was inadequate. Discussion Compared to high-income settings, episiotomy rates are high in LMIC medical facilities. There is an urgent need to improve reporting of BPT in LMICs particularly with regards to births taking in community settings.

Socio-historical evolution of the episiotomy practice: A literature review

Episiotomy is an enlargement of the vaginal orifice made by a surgical incision of the perineum. This review aimed to provide a socio-historical retrospective on the practice or episiotomy. Using the criteria from the PRISMA guidelines, the authors conducted a literature review, browsing twenty databases and several papers available in the gray literature. Sixty-four articles, seven reports, and fifteen books were selected. Through this study, four eras with different approaches to episiotomy practice could be identified: 1792-1920, 1920-1980, 1980-1996, and 1996-2018. This review shows that institutionalization and medicalization of birth lead to a systematic practice of episiotomy in many westernized countries until 1996. Lay questioning and evidence-based medicine may have reversed this trend into a restrictive practice. After making an inventory of the factors associated with the evolution of change in the rate of episiotomies, the review finally revealed that evolution of the practice of episiotomy has also been influenced by ideological, political, and social factors.

Statistical trends of episiotomy around the world: Comparative systematic review of changing practices

The authors' purpose for this article is to identify, review and interpret all publications about the episiotomy rates worldwide. Based on the criteria from the PRISMA guidelines, twenty databases were scrutinized. All studies which include national statistics related to episiotomy were selected, as well as studies presenting estimated data. Sixty-one papers were selected with publication dates between 1995 and 2016. A static and dynamic analysis of all the results was carried out. The assumption for the decline in the number of episiotomies is discussed and confirmed, recalling that nowadays high rates of episiotomy remain in less industrialized countries and East Asia. Finally, our analysis aims to investigate the potential determinants which influence apparent statistical disparities.

Evaluation of training programme uptake in an attempt to reduce obstetric anal sphincter injuries: the SUPPORT programme

INTRODUCTION AND HYPOTHESIS

The objective was to assess the feedback from a quality improvement training programme to reduce obstetric anal sphincter injuries (OASIS).

METHODS

Training sessions were organised that included evidence-based information on OASIS risk factors and training on models to measure perineal body length (PBL), perform episiotomies with standard and 60° fixed angle scissors (EPISCISSORS-60®), and measure post-delivery episiotomy suture angles with protractor transparencies. Feedback forms using a Likert scale (1-4) were completed and analysed. The setting was an evidence-based quality improvement programme (Strategy for Using Practical aids for Prevention of OASIS, Recording episiotomies and clinician Training [SUPPORT]) at two National Health Service (NHS) Hospitals in the UK. The participants were midwives and doctors attending the SUPPORT training programme RESULTS: All of the participants (100 %) would recommend the training programme to a friend or colleague. 92 % felt that the training session improved their knowledge of the impact of PBL and perineal distension and their knowledge of the relationship between episiotomy angle and OASIS "a lot" or "somewhat".

CONCLUSION

Based on this feedback, we recommend the addition of the knowledge content of the SUPPORT programme to other centres providing perineal assessment and repair courses.

[From the impact of French guidelines to reduce episiotomy's rate]

OBJECTIVES

Following the publication of the French Guidelines on episiotomy in 2005 by the French National College of Gynaecologists and Obstetricians (CNGOF), our unit decided to adopt a restrictive politics to replace the former liberal one. The goal of this study was to evaluate the impact of this modification of trend in the Unit of Gynaecology and Obstetrics of the teaching hospital from Caen. This was the start point of an internal audit with the objective of an enhancement of the care during delivery.

PATIENTS AND METHODS

It was a retrospective study concerning the period going from January, 2004 till December, 2009, measuring the impact of the guidelines on the episiotomy rates and perineal tears. The totality of the population of the women naturally delivered at a term superior or equal to 37 weeks of gestation and a cephalic presentation was included. To modify the practices, after diffusion of the guidelines by some obstetrical leaders, we imposed to notify the indication of the episiotomy in the computerized obstetrical files. Moreover, we published monthly screenboards with all the detailed results to all the practioners acting in the delivery room (obstetricians, midwives).

RESULTS

Between 2004 and 2009, we observed a dramatic decline of the episiotomy rates from 55.7 to 13.3%. This trend was the same for primiparae and multiparae, as wall as for spontaneous or assisted delivery (mostly vacuum extraction in our unit). We noticed a slight increased in minor perineal tears without functional consequences. There was no statistically significant difference between severe perineal tear (1.3% vs. 1.1%). By contrary, the rate of intact perineum significantly raised (17.6% vs. 21.7%, p<0.001), especially in vacuum extractions.

DISCUSSION

Our results are in accordance with those of the national guidelines. However, our rate does not decrease in 2007 and 2008 (20%), contrary to some results obtained in the literature. Some reports mentioned the weak impact of the publication of national guidelines to modify the usual practice. However, we believe that retro-information to practitioners has a real impact on their daily current practice. Hence we insisted again on the importance of these national guidelines at the end of 2008 and we could demonstrate a real decline of the rate of episiotomy. Our efforts have to be continued, especially for instrumental delivery.

Mensuração e características da dor perineal em primíparas submetidas à episiotomia

OBJETIVO: Mensurar e caracterizar a percepção dolorosa das puérperas primíparas submetidas à episiotomia. MÉTODOS: Trata-se de uma pesquisa descritiva com abordagem quantitativa, realizada com 40 puérperas primíparas submetidas ao parto normal com episiotomia. Para mensuração da dor foi utilizada a escala de categoria numérica e para caracterização a versão brasileira do questionário McGill - Br-MPQ. RESULTADOS: Os valores encontrados na avaliação da dor foram de média 4,2 e os descritores que melhor caracterizaram a dor foram: dolorida; que repuxa; incômoda; chata; ardida; pica como uma agulhada; latejante; em pressão. CONCLUSÃO: A intensidade da dor perineal foi considerada como moderada pelas puérperas. Na caracterização da queixa dolorosa os descritores mais citados foram da dimensão sensorial. Este estudo possibilitou observar a necessidade do reconhecimento dos aspectos qualitativos e quantitativos da dor na prática clinica obstétrica.
