Women's experiences of induction of labour: Qualitative systematic review and thematic synthesis

Patient experience in prostaglandins-induced cervical ripening: A comparative study using a standardized questionnaire

OBJECTIVE

Cervical ripening for induction of labor is often associated with negative patient experience. The debate over the most effective cervical ripening method persist, with a significant gap in research specifically addressing patient satisfaction. Our study aims to compare patient experience with two induction methods, slow-release intravaginal dinoprostone device and orally administered misoprostol.

METHOD

We conducted a before-and-after comparative study at a university tertiary hospital, including all patients undergoing cervical ripening with a Bishop score of 3 or lower. Our study compared two separate two-month periods, where the methods for cervical ripening differed. The first period employed an intravaginal dinoprostone slow-release device, while the second period used oral misoprostol. The primary outcome was patient experience, assessed using the EXIT questionnaire, a standardized and validated self-reported measure. Secondary outcomes were efficacy and safety outcomes.

RESULTS

A total of 165 patients were included, 81 induced with dinoprostone and 84 induced with misoprostol. The EXIT questionnaire completion rate was 67.9 % (n = 55) in the dinoprostone group and 76.1 % (n = 64) in the misoprostol group (p = 0.23). Patients induced with misoprostol reported higher levels of satisfaction compared to those induced with dinoprostone, which can be attributed to reduced discomfort associated with the induction process (mean satisfaction score 2.26 ± 0.98 versus 2.80 ± 0.85 on a 1 to 5 likert-scale, p-value < 0.01). Adverse effects were reported less frequently with misoprostol compared to dinoprostone (20.2 % vs 48.1 %, p-value < 0.01). Time between cervical ripening and delivery was shorter in the misoprostol group (27.0 ± 10.2 h vs 32.5 ± 10.0, p < 0.01). There were no difference in mode of delivery or other obstetrical and neonatal outcomes.

CONCLUSION

For women undergoing cervical ripening, oral misoprostol appears to be a less invasive method for labor induction, associated with higher levels of satisfaction and reduced discomfort compared to the intravaginal dinoprostone slow-release device.

Women's Experiences of Mechanical Balloon Catheter Induction With Self-Traction

OBJECTIVE

To explore women's experiences of mechanical labor induction using a balloon catheter with self-traction.

DESIGN

Descriptive qualitative.

SETTING

Birth unit of an urban hospital in Quebec, Canada.

PARTICIPANTS

Fourteen women who experienced labor induction with a balloon catheter using self-traction.

METHODS

We conducted individual structured interviews between May 2022 and January 2023 to collect data that we subsequently analyzed using the manifest content analysis approach of Graneheim et al. We adhered to the Consolidated Criteria for Reporting Qualitative Research (COREQ).

RESULTS

We identified five categories: Expectations, Pain or Comfort Experienced, Emotions Felt, Support From Nursing Staff, and Appreciation of the Procedure. The participants anticipated rapid, effective induction, expressed concerns about potential discomfort, and appreciated control of their experiences. We found a generally positive trend in terms of appreciation for all categories.

CONCLUSION

The positive experiences of participants underline the promising potential of the balloon catheter method of labor induction with self-traction. Given the continuing growth in labor induction rates, it becomes necessary to continue efforts to offer services specifically geared to women's needs. Offering an additional option such as self-traction is a step in this direction.

Barriers and facilitators for physical activity in people living with chronic pain: a systematic review and combined analysis

ABSTRACT

Chronic pain is a prevalent and complex health issue associated with physical, emotional, and social consequences. Management of pain is multifactorial and challenging; however, physical activity (PA) has consistently been shown to be beneficial. Despite this, PA levels among people with chronic pain are low. This study aimed to identify facilitators and barriers to PA among adults with chronic pain and analyse these using the structure of a validated behaviour change model: the capability, opportunity, and motivation behaviour change model (COM-B). We performed a systematic review of 6 databases and subsequent combined analysis including peer-reviewed primary research published in English up to November 15, 2023. Search terms consisted of 3 components: pain, PA, and facilitators/barriers. Quality appraisal of studies was conducted using appropriate tools. The systematic search yielded 40 eligible studies with a total of 2164 participants. The studies represented various chronic pain conditions, locations, and study designs. The key barriers to engagement in PA were the impact of pain severity, comorbidities, lack of knowledge about PA benefits, and time constraints. Key facilitators were a personalised approach, social support, and awareness of the benefits. The findings were categorised according to the COM-B model, allowing for the identification of modifiable factors. Person-centred approaches, education, and accessible environments were identified as important aspects to consider for successful PA promotion among people with chronic pain. Utilising the factors identified in the COM-B model is crucial for successful future interventions to increasing PA uptake and adherence in this population.

Outpatient labor induction-Exploring future potential by assessing eligibility in a historical cohort

INTRODUCTION

Labor induction rates have increased over the last decades, and in many high-income countries, more than one in four labors are induced. Outpatient management of labor induction has been suggested in low-risk pregnancies to improve women's birth experiences while also promoting a more efficient use of healthcare resources. The primary aim of this paper was to assess the proportion of women in a historical cohort that would have been eligible for outpatient labor induction with oral misoprostol. Second, we wanted to report safety outcomes and assess efficacy outcomes for mothers and infants in pregnancies that met the criteria for outpatient care.

MATERIAL AND METHODS

Criteria for outpatient labor induction with oral misoprostol were applied to a historical cohort of women with induction of labor at two Norwegian tertiary hospitals in the period January 1, through July 31, 2021. The criteria included low-risk women with an unscarred uterus expecting a healthy, singleton baby in cephalic position at term. The primary outcome was the proportion of women eligible for outpatient labor induction. Secondary outcomes included reasons for ineligibility and, for eligible women, safety and efficacy outcomes.

RESULTS

Overall, 29.7% of the 1320 women who underwent labor induction in a singleton term pregnancy met the criteria for outpatient labor induction. We identified two serious adverse events that potentially could have occurred outside the hospital if the women had received outpatient care. The mean duration from initiation of labor induction to administration of the last misoprostol was 22.4 h. One in 14 multiparous women gave birth within 3 h after the last misoprostol dose.

CONCLUSIONS

In this historical cohort, three in ten women met the criteria for outpatient management of labor induction with oral misoprostol. Serious adverse events were rare. The average time span from the initiation of labor induction to the last misoprostol was nearly 24 h. This suggests a potential for low-risk women with an induced labor to spend a substantial period of time at home before labor onset. However, larger studies testing or evaluating labor induction with oral misoprostol as an outpatient procedure are needed to draw conclusions.

Swedish maternity care professionals' perception of labor induction

BACKGROUND

Sweden recently adopted new labor induction guidelines lowering the threshold for post-term pregnancies to 41+ weeks. Despite evidence-based foundation, these guidelines stirred controversy among maternity care professionals, who voiced concerns about potential risks and unintended consequences, such as a rising Caesarean section rate. Midwives also highlighted potential impacts on their roles, workload, and working environment; implications that could affect obstetricians and gynecologists as well. Investigating Swedish maternity care professionals' views on labor induction could benefit policymakers, managers, and birthing women alike.

AIM

The aim of this study was to describe and compare midwives to obstetricians/gynecologists, with regards to their views on labor induction, and how this relates to other work-related variables such as overall job satisfaction, clinical experience, gender, age, personality, and workload.

METHODS

Swedish midwives (N = 207, 99 % women, M = 45.2 years), and obstetricians/gynecologists (N = 240, 83 % women, M = 44.3 years) responded to an online questionnaire reflecting aspects of maternity care work. The data was analyzed using Welch's t-test and Pearson's correlation analysis.

RESULTS

A large difference was observed in labor induction views between midwives and obstetricians/gynecologists (d = 1.39), as well as lower job satisfaction with midwives (d = -0.26). Overall job satisfaction further correlated negatively with views on labor induction (r = -0.30).

CONCLUSIONS

Labor inductions might pose challenges to midwives and could bring to light underlying tensions between obstetricians/gynecologists and midwives. Given the modest response rate of the study, we cautiously suggest that while the development of new maternity care guidelines should be grounded in evidence, they should also embrace concerns and insights from a diversity of professional perspectives.

Facilitating positive birth experience when preferences are not met: A qualitative analysis

INTRODUCTION

High-quality health systems rely on care that centers on patient preferences. Realization of patient preferences can improve the birth experience. However, in the dynamic setting of birth, birth preferences can diverge from what is medically indicated. Through studying women and birthing peoples' experiences of unplanned labor procedures, we aimed to identify ways in which practitioners can support women and birthing people through unexpected or unwanted aspects of their delivery. Specifically, we focused on labor induction.

METHODS

In one large US academic center, women and birthing people participated in prenatal and postpartum surveys regarding their desires, expectations, and experiences of labor induction. From April to November 2021, participants were eligible if they showed discordance between having labor induction and whether it was initially wanted or expected. Interviews focused on attitudes toward birth preferences and outcomes, with attention to discordances. We analyzed interviews through a modified grounded theory approach.

RESULTS

Of 22 participants, our sample was predominantly white (91%). Participants in this sample reported discordance between wanting and experiencing (73%) and/or expecting and experiencing (54%) an induction. We identified two themes: "Discordance without mitigation is perceived as a negative experience" and "Practitioner interaction can buffer against negative experience" which includes three ways in which participants prefer support in instances of discordance: preparation, communication, and care and comfort. These methods of support foster patient autonomy and can lead to positive patient experiences.

CONCLUSIONS

While medical systems should work to support patient preferences, our results suggest that patients can still have positive birth experiences, even when preferences are not fulfilled. Early practitioner preparation, positive communication, and responsive care and comfort may help to improve patient birth experience when challenges arise.

Diabetes in pregnancy: Women's views of care in a multi-ethnic, low socioeconomic population with midwifery continuity-of-care

BACKGROUND

Diabetes in pregnancy is diagnosed in 6% of pregnancies annually in Aotearoa-New Zealand, disproportionately affecting multi-ethnic, low socio-economic women. Little is known about the care experience of this population within the model of midwifery continuity-of-care, including views of telehealth care.

AIM

Increase understanding of the experience of diabetes in pregnancy care, including telehealth, among multi-ethnic, low socio-economic women receiving midwifery continuity-of-care.

METHODS

Qualitative interview study with primarily indigenous and migrant women who had diabetes in pregnancy and gave birth 6-18 months previously. Interviewers were matched with participants by ethnicity. Transcripts were analysed using Framework analysis.

RESULTS

Participants were 19 women (5 Māori, 5 Pacific Peoples, 5 Asian, 4 European). Data analysis revealed three key themes: 1) 'shock, shame, and adjustment' to the diagnosis 2) 'learning to manage diabetes in pregnancy' and 3) 'preparation for birth and beyond' to the postpartum period.

DISCUSSION

Receiving the diagnosis of diabetes in pregnancy was a shock. Managing diabetes during pregnancy was particularly challenging for indigenous and migrant women, who wished for better access to culturally appropriate dietary and lifestyle information. Women appreciated having options of telehealth and face-to-face consultations. Preparation for birth and postpartum diabetes follow-up were areas requiring significant improvement. Challenges were mitigated through care from a consistent diabetes specialist midwife and community-based midwifery continuity-of-care.

CONCLUSION

Midwives were the backbone of diabetes in pregnancy care for this multi-ethnic, low socio-economic population. Care could be improved with more culturally appropriate diet and lifestyle information, better birth preparation, and expanded postpartum diabetes support.

Key dimensions of women's and their partners' experiences of childbirth: A systematic review of reviews of qualitative studies

BACKGROUND

The World Health Organization 2018 intrapartum guideline for a positive birth experience emphasized the importance of maternal emotional and psychological well-being during pregnancy and the need for safe childbirth. Today, in many countries birth is safe, yet many women report negative and traumatic birth experiences, with adverse effects on their and their families' well-being. Many reviews have attempted to understand the complexity of women's and their partners' birth experience; however, it remains unclear what the key dimensions of the birth experience are.

OBJECTIVE

To synthesize the information from reviews of qualitative studies on the experience of childbirth in order to identify key dimensions of women's and their partners' childbirth experience.

METHODS

Systematic database searches yielded 40 reviews, focusing either on general samples or on specific modes of birth or populations, altogether covering primary studies from over 35,000 women (and >1000 partners) in 81 countries. We appraised the reviews' quality, extracted data and analysed it using thematic analysis.

FINDINGS

Four key dimensions of women's and partners' birth experience (covering ten subthemes), were identified: 1) Perceptions, including attitudes and beliefs; 2) Physical aspects, including birth environment and pain; 3) Emotional challenges; and 4) Relationships, with birth companions and interactions with healthcare professionals. In contrast with the comprehensive picture that arises from our synthesis, most reviews attended to only one or two of these dimensions.

CONCLUSIONS

The identified key dimensions bring to light the complexity and multidimensionality of the birth experience. Within each dimension, pathways leading towards negative and traumatic birth experiences as well as pathways leading to positive experiences become tangible. Identifying key dimensions of the birth experience may help inform education and research in the field of birth experiences and gives guidance to practitioners and policy makers on how to promote positive birth experiences for women and their partners.

The role of acupuncture in the present approach to labor induction: a systematic review and meta-analysis

OBJECTIVE

This study aimed to evaluate the bibliographic references available on the contribution of acupuncture as a strategy to avoid labor induction and the methodology used; and explore the characteristics of the population and the results of the intervention in order to direct the design of future studies.

DATA SOURCE

A systematic search for publications between January 2000 and September 2023 of the CENTRAL, PubMed, CINAHL, SCOPUS, ClinicalTrials.gov, and EUDRACT databases was performed.

STUDY ELIGIBILITY CRITERIA

We included randomized clinical trials of pregnant women who underwent acupuncture before labor induction with a filiform needle or acupressure, including at least 1 of the following outcomes: spontaneous labor rate, time from procedure to delivery, and cesarean delivery rate. Articles published in English or German language were included.

METHODS

Whenever possible, a meta-analysis using RevMan software was performed using a random effects model with the I2 statistic because important heterogeneity in the different acupuncture treatments was expected. When enough data were available, the effect of the participants' characteristics on the results of the interventions were explored using the following subgroups: 1-Age (≥35 vs <35 years), and 2- body mass index (≥30 vs <30 kg/m2). When a meta-analysis was not possible, a narrative synthesis of the results was performed. The quality of the evidence was assessed using GRADE.

RESULTS

Seventeen studies including 3262 women fulfilled our inclusion criteria. The meta-analysis showed no statistically significant differences between groups for outcomes (relative risk, 1.00; 95% confidence interval, 0.91-1.10; I2, 11%) comparing acupuncture vs sham acupuncture. However, there was a statistically significant increase in the spontaneous onset of labor rate favoring acupuncture vs no acupuncture (relative risk, 1.12; 95% confidence interval, 1.03-1.23; I2, 25%). Regarding the age analysis, no differences between groups were observed in the spontaneous labor rate and cesarean delivery rate for acupuncture vs sham and acupuncture vs no acupuncture comparisons (difference between groups, P>.05).

CONCLUSION

This study suggests that acupuncture may be beneficial in reducing the rate of induction of labor; however, well-designed randomized controlled trials are necessary. Maternal age ≥35 years and a high body mass index were underrepresented, and the findings may not be representative of the current population in our context.

Perceptions of healthcare professionals regarding labour induction and augmentation: A qualitative systematic review

BACKGROUND

Labour induction and augmentation procedures are commonly used in maternity units with or without medical indications. Research shows that healthcare professionals play a significant role in women's childbirth decisions.

AIM

To consolidate healthcare professionals' perceptions about labour induction and augmentation.

METHODS

Seven electronic databases were searched from their inception dates till January 2023: PubMed, Embase, CINAHL, PsycINFO, Web of Science, Scopus, ProQuest Dissertations, and Theses Global. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis and Sandelowski and Barroso's guidelines guided this review. Included studies' quality was appraised by the Critical Appraisal Skills Program tool. Data were thematically synthesised. Review findings were assessed using the Grading of Recommendations Assessment, Development, and Evaluation-Confidence in the Evidence from Reviews of Qualitative research approach.

FINDINGS

Three main themes were identified from the 17 included studies: 1) Making sense of the phenomenon, 2) Two sides of the coin, and 3) The enlightened path ahead.

DISCUSSION

Healthcare professionals' labour induction and augmentation decisions were affected by personal (knowledge and moral philosophies), and external factors (women, community members, colleagues, and healthcare institutions). Some clinicians were unfamiliar with the proper labour induction/augmentation procedures, while others were worried about their decisions and outcomes.

CONCLUSION

Suggestions for improvement include conducting labour induction/augmentation training for clinicians, having sufficient resources in facilities, and developing appropriate labour induction/augmentation clinical guidelines. Women and their partners, community members, and traditional healers could benefit from receiving labour induction/augmentation education. To improve health outcomes, healthcare professionals could deliver woman-centred care and collaborate.

From "disappointing" to "fantastic": Women's experiences with labor induction in a U.S. tertiary hospital

OBJECTIVE

The series of interventions that comprise labor induction shape patient experiences; however, patient perceptions are not always considered when structuring the process of care. Through qualitative interviews, we elucidated women's expectations and experiences regarding labor induction.

METHODS

Labor induction patients were recruited from a United States tertiary care hospital's postpartum mother-baby unit and invited to participate in semi-structured qualitative interviews. Interview questions included expectations and experiences of the labor induction process, side effects and health outcomes of concern, reflections on personal tolerance of different interventions, and thoughts about an ideal process.

RESULTS

Between April and September 2018, 36 women were interviewed. The labor induction process involved a wide range of experiences; when asked to characterize labor induction in one word, responses ranged from horrible, frustrating, and terrifying to simple, fast, and smooth. Inductions were often described as longer than what was expected. The most polarizing induction method was the Foley balloon catheter. Women's concerns regarding side effects largely centered on the health of their baby, and an ideal induction involved fewer interventions.

CONCLUSIONS

Experiences with labor induction vary greatly and are related to expectations. The way interventions are introduced influences women's perceptions of control and their ultimate level of contentment with the birthing process. Attention to experiences and preferences has the potential to improve quality of care through communication, shared decision-making, and education.

Women's experiences and views of outpatient and inpatient induction of labor with oral misoprostol: A secondary qualitative study

INTRODUCTION

As labor induction rates continue to increase, so has the interest in performing induction in an outpatient setting for pregnancies defined as low-risk. Twenty women participated in the pilot study of a Randomized Controlled Trial (RCT) comparing inpatient and outpatient labor induction with oral misoprostol. This study aimed to explore women's experiences of outpatient induction of labor and their views on this as an alternative method to inpatient labor induction.

METHODS

Semi-structured interviews were conducted, from November 2021 to January 2022 with eight women randomized to outpatient induction and four women randomized to inpatient induction. Verbatim transcribed interviews were analyzed using Graneheim and Lundman's content analysis.

RESULTS

Three main categories emerged: the required framework around outpatient labor induction, what felt better at home and what felt safer at the hospital. To feel secure at home, women needed sufficient information, close follow-up while at home, and an easy-to-administer induction method. Outpatient labor induction gave women the opportunity of constant support from the partner and increased freedom of movement and self-expression. Some expressed relief over being randomized to inpatient labor induction, because of easy access to health providers, fetal monitoring, and not risking giving birth before arrival to the hospital. Women stressed the importance of being given a choice.

CONCLUSIONS

Outpatient labor induction contributed to a positive birth experience and should be considered as an alternative for women with low-risk pregnancies. Shared decision-making, including the opportunity for women to change their mind, is essential as induction and early labor affects women's whole childbirth experience.

Predictors of maternal satisfaction with labor induction: A prospective observational cohort study

OBJECTIVE

To identify independent predictors of maternal satisfaction with labor induction.

METHOD

In this prospective observational cohort study, 769 women prior to their labor induction had sleep and psychological well-being assessed using Pittsburgh Sleep Quality Index and Depression, Anxiety and Stress Scales. Women were asked about the adequacy of labor induction information provided and their involvement and time pressure felt in the decision-making for their labor induction. Maternal characteristics, induction and intrapartum care measures, and labor and neonatal outcomes were also assessed. Prior to discharge, women rated their satisfaction with their birth experience.

RESULTS

A total of 34 variables were considered for bivariate analysis, with 15 found to have P < 0.05. Following adjusted analysis, 10 independent predictors of maternal satisfaction were identified: maternal education, previous cesarean delivery, maternal involvement, information provided, and decision-making time pressure regarding labor induction, amniotomy, induction to delivery interval, mode of delivery, postpartum hemorrhage, and neonatal admission. Maternal satisfaction was not associated with sleep, depression, anxiety, or stress.

CONCLUSION

The identification of independent predictors of maternal satisfaction allows for patient selection, targeting of specific preinduction and intrapartum care, and focus on induction methods that can reduce induction to delivery interval, cesarean birth, and delivery blood loss to maximize women's satisfaction with labor induction.

Exposing the Role of Labor and Delivery Nurses as Active Bystanders in Preventing or Perpetuating Obstetric Violence

Obstetric violence is an issue of global scope and magnitude. Its widespread and continued presence indicates cultural tolerance enabled by policies and procedures that uphold paternalism. Labor and delivery nurses are the health care professionals who spend the most time at the point of care during birth, and their role must be examined. As active bystanders, labor and delivery nurses are uniquely positioned to prevent or perpetuate obstetric violence during labor and birth. Reflection on the nurse role is necessary to provide optimal care, enhance relationships with patients, and continue to evolve as a professional discipline. Perinatal nurses must lead the change to trauma-informed care practices to mitigate obstetric violence and reduce birth trauma.

Primary postpartum haemorrhage and longer-term physical, psychological, and psychosocial health outcomes for women and their partners in high income countries: A mixed-methods systematic review

OBJECTIVES

Most research about outcomes following postpartum haemorrhage (PPH) has focused on immediate outcomes. There are fewer studies investigating longer-term maternal morbidity following PPH, resulting in a significant knowledge gap. This review aimed to synthesize the evidence about the longer-term physical and psychological consequences of primary PPH for women and their partners from high income settings.

METHODS

The review was registered with PROSPERO and five electronic databases were searched. Studies were independently screened against the eligibility criteria by two reviewers and data were extracted from both quantitative and qualitative studies that reported non-immediate health outcomes of primary PPH.

RESULTS

Data were included from 24 studies, of which 16 were quantitative, five were qualitative and three used mixed-methods. The included studies were of mixed methodological quality. Of the nine studies reporting outcomes beyond five years after birth, only two quantitative studies and one qualitative study had a follow-up period longer than ten years. Seven studies reported outcomes or experiences for partners. The evidence indicated that women with PPH were more likely to have persistent physical and psychological health problems after birth compared with women who did not have a PPH. These problems, including PTSD symptoms and cardiovascular disease, may be severe and extend for many years after birth and were more pronounced after a severe PPH, as indicated by a blood transfusion or hysterectomy. There was limited evidence about outcomes for partners after PPH, but conflicting evidence of association between PTSD and PPH among partners who witnessed PPH.

CONCLUSION

This review explored existing evidence about longer-term physical and psychological health outcomes among women who had a primary PPH in high income countries, and their partners. While the evidence about health outcomes beyond five years after PPH is limited, our findings indicate that women can experience long lasting negative impacts after primary PPH, including PTSD symptoms and cardiovascular disease, extending for many years after birth.

Regional practice variation in induction of labor in the Netherlands: Does it matter? A multilevel analysis of the association between induction rates and perinatal and maternal outcomes

BACKGROUND

Practice variation in healthcare is a complex issue. We focused on practice variation in induction of labor between maternity care networks in the Netherlands. These collaborations of hospitals and midwifery practices are jointly responsible for providing high-quality maternity care. We explored the association between induction rates and maternal and perinatal outcomes.

METHODS

In a retrospective population-based cohort study, we included records of 184,422 women who had a singleton, vertex birth of their first child after a gestation of at least 37 weeks in the years 2016-2018. We calculated induction rates for each maternity care network. We divided networks in induction rate categories: lowest (Q1), moderate (Q2-3) and highest quartile (Q4). We explored the association of these categories with unplanned caesarean sections, unfavorable maternal outcomes and adverse perinatal outcomes using descriptive statistics and multilevel logistic regression analysis corrected for population characteristics.

FINDINGS

The induction rate ranged from 14.3% to 41.1% (mean 24.4%, SD 5.3). Women in Q1 had fewer unplanned caesarean sections (Q1: 10.2%, Q2-3: 12.1%; Q4: 12.8%), less unfavorable maternal outcomes (Q1: 33.8%; Q2-3: 35.7%; Q4: 36.3%) and less adverse perinatal outcomes (Q1: 1.0%; Q2-3: 1.1%; Q4: 1.3%). The multilevel analysis showed a lower unplanned caesarean section rate in Q1 in comparison with reference category Q2-3 (OR 0.83; p = .009). The unplanned caesarean section rate in Q4 was similar to the reference category. No significant associations with unfavorable maternal or adverse perinatal outcomes were observed.

CONCLUSION

Practice variation in labor induction is high in Dutch maternity care networks, with limited association with maternal outcomes and no association with perinatal outcomes. Networks with low induction rates had lower unplanned caesarean section rates compared to networks with moderate rates. Further in-depth research is necessary to understand the mechanisms that contribute to practice variation and the observed association with unplanned caesarean sections.

Pregnant persons and birth partners' experiences of shared decision-making during pregnancy and childbirth: An umbrella review

OBJECTIVES

This umbrella review aimed to summarize evidence on pregnant persons and/or their birth partners' experiences and expectations of SDM during pregnancy and childbirth.

METHODS

We searched eight databases from 2011 to 2023. Quantitative, qualitative and mixed methods systematic reviews were included in this review.

RESULTS

We have identified 26 reviews that report on 622 primary studies involving over 213,000 pregnant persons and 22,000 birth partners, examining a broad range of decision-making scenarios in maternity care. The three-talk model was used to categorise the themes which include communication, weighing options, and making a decision. Multiple reviews have reported that pregnant persons and birth partners have mixed experiences in several decision-making scenarios, with insufficient information and inadequate consideration or answers to their questions being common issues. Pregnant persons and birth partners prefer clear explanations, simple communication, and involvement in decision-making. Exclusion from the decision-making during pregnancy and childbirth may lead to negative experiences, whilst involvement improves satisfaction, reduces distress and fosters empowerment.

CONCLUSIONS

The review highlights the importance of promoting SDM in maternity care, as it is fundamental to promoting maternal, newborn, and family well-being.

PRACTICE IMPLICATIONS

Health systems should redesign antenatal classes and train healthcare providers to enhance communication skills and encourage informed decision-making by pregnant persons and birth partners.

Predictive Value of Cervical Shear Wave Elastography in the Induction of Labor in Late-Term Pregnancy Nulliparous Women: Preliminary Results

The prediction of induction of labor continues to be a paradigm nowadays. Bishop Score is the traditional widely spread method but with a low reliability. Ultrasound cervical assessment has been proposed as an instrument of measurement. Shear wave elastography (SWE) should be a promising tool in the prediction of the success of labor induction in nulliparous late-term pregnancies. Ninety-two women with nulliparous late-term pregnancies who were going to be induced were included in the study. A shear wave measurement of the cervix divided into six regions (inner, middle and outer in both cervical lips), cervical length and fetal biometry was performed by blinded investigators prior to routine hand cervical assessment (Bishop Score (BS)) and induction of labor. The primary outcome was success of induction. Sixty-three women achieved labor. Nine women did not, and they underwent a cesarean section due to failure to induce labor. SWE was significantly higher in the inner part of the posterior cervix (p < 0.0001). SWE showed an area under the curve (AUC): 0.809 (0.677-0.941) in the inner posterior part. For CL, AUC was 0.816 (0.692-0.984). BS AUC was 0.467 (0.283-0.651). The ICC of inter-observer reproducibility was ≥0.83 in each region of interest (ROI). The cervix elastic gradient seems to be confirmed. The inner part of the posterior cervical lip is the most reliable region to predict induction of labor results in SWE terms. In addition, cervical length seems to be one of the most important procedures in the prediction of induction. Both methods combined could replace the Bishop Score.

Experience of induction of labour: a cross-sectional postnatal survey of women at UK maternity units

OBJECTIVES

This study explored women's views and experiences of key elements of the induction of labour (IOL) process, including at home or in hospital cervical ripening (CR).

DESIGN

A questionnaire-based postnatal survey undertaken as part of the CHOICE Study process evaluation. The questionnaire was administered online and included fixed response and free-text options.

SETTING

National Health Service maternity units in the UK.

PARTICIPANTS

309 women who had an IOL.

OUTCOME MEASURES

The primary outcome measure was experience of IOL. Few women returned home during CR, meaning that statistical comparison between those who experienced home-based and hospital-based CR was not possible. Findings are reported as descriptive statistics with content analysis of women's comments providing context.

RESULTS

Information to support choice and understand what to expect about IOL is often inadequate or unavailable. Having IOL can create anxiety and remove options for birth that women had hoped would enhance their experience. Although it can provide a more comfortable environment, home CR is not always an acceptable solution. Women described maternity care negatively impacted by staffing shortages; delays to care sometimes led to unsafe situations. Women who had a positive experience of IOL described supportive interaction with staff as a significant contribution to that.

CONCLUSIONS

Women do not experience IOL as a benign and consequence free intervention. There is urgent need for research to better target IOL and optimise safety and experience for women and their babies. Relatively few women were offered CR at home and further research is needed on this experience.

Women’s experiences with unexpected induction of labor: A qualitative study

INTRODUCTION

Induction of labor is the most common intervention in modern obstetrics and is a growing phenomenon worldwide. Research on women’s experiences with the induction of labor is scarce, especially on being unexpectedly induced. The purpose of this study is to explore women’s experiences with unexpected induction of labor.

METHODS

We conducted a qualitative study including 11 women who had undergone an unexpected induction of labor within the last three years. Semi-structured interviews were conducted in the period February–March 2022. Data were analyzed using systematic text condensation (STC).

RESULTS

The analysis led to four result categories. The decision to induce labor came as a surprise to the women, both for better and for worse. Information was not automatically provided and was often obtained through the women’s own efforts. Consent to the induction mainly took the form of a decision by healthcare personnel, and the birth was a positive experience during which the woman felt looked after and reassured.

CONCLUSIONS

The women were very surprised when told they had to be induced and were unprepared for the situation. They received insufficient information, and several experienced stress from the time of induction up until they gave birth. Despite this, the women were satisfied with the positive birth experience, and they emphasized the importance of being looked after by empathetic midwives during childbirth.

Obstetric Violence among Pregnant Jordanian Women: An Observational Study between the Private and Public Hospitals in Jordan

BACKGROUND

Obstetric Violence (OV) is a public health matter that affects women and their children with an incidence rate between 18.3-75.1% globally. The delivery institution of public and private sectors represents a potential factor contributing to OV. This study aimed to assess OV existence among sample of pregnant Jordanian women and its risk factors domains between public and private hospitals.

METHODOLOGY

This is a case-control study including 259 recently delivered mothers from Al-Karak Public and Educational Hospital and The Islamic Private Hospital. A designated questionnaire including demographic variables and OV domains was used for data collection.

RESULTS

A significant difference was seen between patients delivering in the public sector compared to patients delivering the private sector in education level, occupation, monthly income, delivery supervision and overall satisfaction. Patients delivering in the private sector showed a significantly less physical abuse by the medical staff compared to patients delivering in the public sector, and patients delivering in a private room also showed a significantly less OV and risk of physical abuse compared to patients delivering in shared room. In public settings, medications information was lesser versus the private ones, additionally, there is significant association between performing episiotomy, physical abuse by staff and the delivery in shared rooms in private settings.

CONCLUSION

This study showed that OV was less susceptible during childbirth in private settings compared to public settings. Educational status, low monthly income, occupation are risk factors for OV; also, features of disrespect and abuse like obtaining consent for episiotomy performance, delivery provision updates, care perception based on payment ability and medication information were reported.

Pharmacological Interventions in Labor and Delivery

While there is not a wide range of pregnancy-specific drugs, there are some very specific high-risk areas of obstetric care for which unique pharmacological approaches have been established. In preterm birth, labor induction and augmentation, and the management of postpartum hemorrhage, these pharmacological approaches have become the bedrock in managing some of the most common and problematic areas of antenatal and intrapartum care. In this review, we summarize the existing established and emerging evidence that supports and broadens these pharmacological approaches to obstetric management and its impact on clinical practice. It is clear that existing therapeutics are limited. They have largely been developed from our knowledge of the physiology of the myometrium and act on hormonal receptors and their signaling pathways or on ion channels influencing excitability. Newer drugs in development are mostly refinements of these two approaches, but novel agents from plants and improved formulations are also discussed.

Clinicians' perspectives and experiences of providing cervical ripening at home or in-hospital in the United Kingdom

Induction of labour, or starting labour artificially, is offered when the risks of continuing pregnancy are believed to outweigh the risks of the baby being born. In the United Kingdom, cervical ripening is recommended as the first stage of induction. Increasingly, maternity services are offering this outpatient or 'at home', despite limited evidence on its acceptability and how different approaches to cervical ripening work in practice. There is also a paucity of literature on clinicians' experiences of providing induction care in general, despite their central role in developing local guidelines and delivering this care. This paper explores induction, specifically cervical ripening and the option to return home during that process, from the perspective of midwives, obstetricians and other maternity staff. As part of a process evaluation involving five case studies undertaken in British maternity services, interviews and focus groups were conducted with clinicians who provide induction of labour care. The thematic findings were generated through in-depth analysis and are grouped to reflect key points within the process of cervical ripening care: 'Implementing home cervical ripening', 'Putting local policy into practice', 'Giving information about induction' and 'Providing cervical ripening'. A range of practices and views regarding induction were recorded, showing how the integration of home cervical ripening is not always straightforward. Findings demonstrate that providing induction of labour care is complex and represents a significant workload. Home cervical ripening was seen as a solution to managing this workload; however, findings highlighted ways in which this expectation might not be borne out in practice. More comprehensive research is needed on workload impacts and possible lateral effects within other areas of maternity services.

Labor induction information leaflets—Do women receive evidence-based information about the benefits and harms of labor induction?

Objectives

To determine the extent to which a sample of NHS labor induction leaflets reflects evidence on labor induction.

Setting

Audit of labor induction patient information leaflets—local from WILL trial (When to Induce Labor to Limit risk in pregnancy hypertension) internal pilot sites or national-level available online.

Methods

Descriptive analysis [n = 21 leaflets, 19 (one shared) in 20 WILL internal pilot sites and 2 NHS online] according to NHS “Protocol on the Production of Patient Information” criteria: general information (including indications), why and how induction is offered (including success and alternatives), and potential benefits and harms.

Results

All leaflets described an induction indication. Most leaflets (n = 18) mentioned induction location and 16 the potential for delays due to delivery suite workloads and competing clinical priorities. While 19 leaflets discussed membrane sweeping (17 as an induction alternative), only 4 leaflets mentioned balloon catheter as another mechanical method. Induction success (onset of active labor) was presented by a minority of leaflets (n = 7, 33%), as “frequent” or in the “majority”, with “rare” or “occasional” failures. Benefits, harms and outcomes following induction were not compared with expectant care, but rather with spontaneous labor, such as for pain (n = 14, with nine stating more pain with induction). Potential benefits of induction were seldom described [n = 7; including avoiding stillbirth (n = 4)], but deemed to be likely. No leaflet stated vaginal birth was more likely following induction, but most stated Cesarean was not increased (n = 12); one leaflet stated that Cesarean risks were increased following induction. Women's satisfaction was rarely presented (n = 2).

Conclusion

Information provided to pregnant women regarding labor induction could be improved to better reflect women's choice between induction and expectant care, and the evidence upon which treatment recommendations are based. A multiple stakeholder-involved and evidence-informed process to update guidance is required.

Using the WHO-INTEGRATE evidence-to-decision framework to develop recommendations for induction of labour

BACKGROUND

In 2019, WHO prioritized updating recommendations relating to three labour induction topics: labour induction at or beyond term, mechanical methods for labour induction, and outpatient labour induction. As part of this process, we aimed to review the evidence addressing factors beyond clinical effectiveness (values, human rights and sociocultural acceptability, health equity, and economic and feasibility considerations) to inform WHO Guideline Development Group decision-making using the WHO-INTEGRATE evidence-to-decision framework, and to reflect on how methods for identifying, synthesizing and integrating this evidence could be improved.

METHODS

We adapted the framework to consider the key criteria and sub-criteria relevant to our intervention. We searched for qualitative and other evidence across a variety of sources and mapped the eligible evidence to country income setting and perspective. Eligibility assessment and quality appraisal of qualitative evidence syntheses was undertaken using a two-step process informed by the ENTREQ statement. We adopted an iterative approach to interpret the evidence and provided both summary and detailed findings to the decision-makers. We also undertook a review to reflect on opportunities to improve the process of applying the framework and identifying the evidence.

RESULTS

Using the WHO-INTEGRATE framework allowed us to explore health rights and equity in a systematic and transparent way. We identified a lack of qualitative and other evidence from low- and middle-income settings and in populations that are most impacted by structural inequities or traditionally excluded from research. Our process review highlighted opportunities for future improvement, including adopting more systematic evidence mapping methods and working with social science researchers to strengthen theoretical understanding, methods and interpretation of the evidence.

CONCLUSIONS

Using the WHO-INTEGRATE evidence-to-decision framework to inform decision-making in a global guideline for induction of labour, we identified both challenges and opportunities relating to the lack of evidence in populations and settings of need and interest; the theoretical approach informing the development and application of WHO-INTEGRATE; and interpretation of the evidence. We hope these insights will be useful for primary researchers as well as the evidence synthesis and health decision-making communities, and ultimately contribute to a reduction in health inequities.

Impact of Mental Health First Aid Training Courses on Patients’ Mental Health

Background

With the prevalence of mental issues worldwide, more and more people are suffering from psychological torture. Mental Health Gap Action Program (mhGAP) has been introduced to improve the life quality of humans.

Objectives

To explore and synthesize evidence of participants' experience of mental health first aid (MHFA) training course.

Method

Peer-reviewed qualitative evidence was systematically reviewed and thematically synthesized. Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medical Literature Analysis and Retrieval System Online (MEDLINE), Psychological Information (PsycINFO), PubMed, Psych ARTICLES, Web of Science, Joanna Briggs Institute (JBI), and National Institute for Health and Care Excellence (NICE) databases were searched for the inception of the present study. The study's quality was appraised using the Critical Appraisal Checklist for Qualitative Research of Joanna Briggs Institute (JBI) appraisal tool. All the participants who have attended the MHFA training course (excluding instructors) setting were included.

Results

Six papers published between 2005 and 2019 were included for thematic synthesis. The review indicated that MHFA had been a positive experience for participants.

Conclusions

MHFA courses can provide participants with professional knowledge of mental health counseling and improve their knowledge, practice, and attitudes towards their patients. Professional MHFA training courses should therefore be popularized and promoted among other populations.

Maternal characteristics as indications for routine induction of labor: A nationwide retrospective cohort study

BACKGROUND

Maternal characteristics, such as parity and age, are increasingly considered indications for routine induction of labor of otherwise healthy women to prevent fetal and neonatal mortality. To fully balance the risks and benefits of induction of labor, we examined the association of additional relevant maternal characteristics and gestational age with fetal and neonatal mortality.

METHODS

We conducted a nationwide retrospective cohort study among a healthy Dutch population consisting of all singleton pregnancies in midwife-led care after 37 weeks of gestation in the period 2000-2018. We examined the association of maternal ethnicity, age, parity, and socioeconomic status with fetal and neonatal mortality, stratified by gestational age. The association of single characteristics was examined using descriptive statistics, and univariable and multivariable logistics regression analyses. The associations of multiple characteristics were examined using inter-categorical analyses and using interaction terms in the multivariable logistic regression analyses.

RESULTS

The results showed that ethnicity, age, parity, socioeconomic status, and gestational age did not act as single determinant of fetal and neonatal mortality. The probability of fetal and neonatal mortality differed among subgroups of women depending on which determinants were considered and the number of determinants included.

CONCLUSIONS

Decision-making about induction of labor to prevent fetal and neonatal mortality based on a single determinant may lead to overuse or underuse of IOL. A value-based health care strategy, addressing social inequity, and investing in better screening and diagnostic methods that employ an individualized and multi-determinant approach may be more effective at preventing fetal and neonatal mortality.

Evaluating misoprostol and mechanical methods for induction of labour: Scientific Impact Paper No. 68 April 2022

Increasingly, births around the world are started artificially using medications or other methods. This process is known as induction of labour. As it becomes more common, methods are needed to meet the different clinical needs and birth preferences of women. Induction of labour typically includes a combination of the medication dinoprostone inserted into the vagina, artificial rupture of membranes ('releasing the waters'), and synthetic oxytocin (hormone given via a drip). This paper reviews some of the methods less commonly used for induction in the UK, namely a drug called misoprostol, which can be given orally or vaginally, and 'mechanical' methods, where labour is started by stretching the cervix (neck of the womb), most commonly with a soft silicone tube with a balloon near the tip, filled with water. Low-dose oral misoprostol tablets are now commercially available in the UK. Other methods for labour induction are not reviewed in detail in this paper. The evidence suggests mechanical induction of labour (using a balloon catheter) and misoprostol are both at least as safe and effective as using the standard drug, dinoprostone. There is evidence to suggest a balloon catheter may reduce the chance of serious negative outcomes for babies when compared with dinoprostone, and that giving low-dose oral misoprostol results in fewer caesarean births. Where possible and after informed consent, the method of induction of labour should be personalised to suit the individual woman, her clinical condition, and the setting in which she is giving birth. Local contexts and resources also need to be taken into account. To date, research into women's perspectives and experiences of induction of labour have been significantly lacking.

Outcomes of induction versus spontaneous onset of labour at 40 and 41 GW: findings from a prospective database, Sri Lanka

Objectives

The World Health Organization recommends induction of labour (IOL) for low risk pregnancy from 41 + 0 gestational weeks (GW). Nevertheless, in Sri Lanka IOL at 40 GW is a common practice. This study compares maternal/newborn outcomes after IOL at 40 GW (IOL40) or 41 GW (IOL41) versus spontaneous onset of labour (SOL).

Methods

Data were extracted from the routine prospective individual patient database of the Soysa Teaching Hospital for Women, Colombo. IOL and SOL groups were compared using logistic regression.

Results

Of 13,670 deliveries, 2359 (17.4%) were singleton and low risk at 40 or 41 GW. Of these, 456 (19.3%) women underwent IOL40, 318 (13.5%) IOL41, and 1585 (67.2%) SOL. Both IOL40 and IOL41 were associated with an increased risk of any maternal/newborn negative outcomes (OR = 2.21, 95%CI = 1.75–2.77, p < 0.001 and OR = 1.91, 95%CI = 1.47–2.48, p < 0.001 respectively), maternal complications (OR = 2.18, 95%CI = 1.71–2.77, p < 0.001 and OR = 2.34, 95%CI = 1.78–3.07, p < 0.001 respectively) and caesarean section (OR = 2.75, 95%CI = 2.07–3.65, p < 0.001 and OR = 3.01, 95%CI = 2.21–4.12, p < 0.001 respectively). Results did not change in secondary and sensitivity analyses.

Conclusions

Both IOL groups were associated with higher risk of negative outcomes compared to SOL. Findings, potentially explained by selection bias, local IOL protocols and CS practices, are valuable for Sri Lanka, particularly given contradictory findings from other settings.

Elective Induction of Labor or Expectant Management: Outcomes Among Nulliparous Women with Uncomplicated Pregnancies

INTRODUCTION

Cesarean birth rates among women who are nulliparous with uncomplicated full-term pregnancies have been shown to decrease if labor is electively induced. The purpose of this study was to compare the cesarean birth rate for women with pregnancies at 39.0 weeks' gestation or later admitted for spontaneous labor or medically indicated induction of labor (IOL) with that of women receiving elective IOL at term.

METHODS

A retrospective cohort study was conducted by searching electronic health records of all nulliparous women with uncomplicated pregnancies who gave birth between January 2018 through February 2020 at one academic medical center. Select maternal demographic data and approach to labor management were the primary variables analyzed in determining the odds of cesarean birth.

RESULTS

A total of 1528 women were included in this study. Among these, 158 received elective IOL, and 1370 did not. The cesarean birth rates (31.0% vs 23.9%, elective induction of labor vs expectant management, respectively, P = .048), neonatal intensive care admissions (9.5% vs 7.6%, P = .41), and Apgar scores were similar among women in both management groups, respectively (P = .08). Accounting for other potential risk factors, the odds of having cesarean birth were not statistically different between management groups (adjusted odds ratio, 0.73; 95% CI, 0.5-1.1; P = .09). There were 2 fetal deaths among women whose labor was not electively induced. In the total cohort, women who were older, who had higher body mass index (BMI), and who identified as non-Hispanic Black had an increased odds of experiencing a cesarean birth. The associations between women in management groups and cesarean birth were not modified by age, BMI, race, or ethnicity (P = .33, .67, and .87, respectively).

DISCUSSION

Elective IOL was not associated with lower cesarean rates in this study. Further research is needed before implementing clinical practice changes that encourage more use of IOL.

How is patient-centred care conceptualized in obstetrical health? comparison of themes from concept analyses in obstetrical health- and patient-centred care

Background

Due to gender inequities that exist for women of childbearing age, there exists a need to deliver care tailored to their needs and preferences. Patient‐centred care (PCC) can be used to meet these needs. This review aims to compare patient care delivery between PCC and obstetrical care. This can help us address how PCC should be delivered to women before, during and after pregnancy versus how it is delivered to patients regardless of sex.

Methods

A review of literature was conducted on MEDLINE, EMBASE, CINAHL and SCOPUS for English PCC and high‐quality perinatal reviews published between 2010 and 2021. The data were analysed using a modified Walker and Avant framework.

Results

A total of 2138 unique studies were identified, with 11 PCC and 9 high‐quality obstetrical care studies included. Common defining features between PCC and obstetrical care include respect and dignity, informed decision‐making, therapeutic alliance, effective communication, social relationships and autonomy. PCC‐specific features were holistic care, empowerment, individualized care, coordinated care and empathy. Unique high‐quality obstetrical care themes included continuity of care, privacy and confidentiality, provider education and status, physical environment and equitable maternal care.

Conclusions

There are shared defining attributes between PCC and obstetrical care, including respect and dignity, informed decision‐making, the therapeutic alliance, effective communication, social relationships and autonomy. However, there remain unique defining attributes for high‐quality obstetrical care and PCC. This highlights the need for a unique approach to obstetrical care. More research on care for different physiological conditions in women is needed to address patient care that addresses different parts of the lifespan and develop frameworks that can influence health policy, patient care and health system evaluation.

Patient or Public Contribution

This study was one part of a larger, multicomponent study of how to implement PCC for women across the lifespan. While we did not specifically consult or involve women in this dual concept analysis, our larger study (content analysis of clinical guidelines and government policies, qualitative interviews with women and clinicians, Delphi study to prioritize consensus recommendations for achieving PCC for women) was guided by the experiences and input of a 50+ women advisory panel.

Oral misoprostol tablets (25 µg) for induction of labor: a targeted literature review and cost analysis

BACKGROUND

Various methods exist for the induction of labor (IOL), and there is limited consensus as to optimal methods. Off-label misoprostol is recommended by the World Health Organization (WHO) for IOL but preparing it into doses suitable for IOL lacks precision, with potential adverse outcomes if dosing is inaccurate. This study explores potential outcomes and costs associated with increased uptake of a low-dose (25 µg) oral misoprostol formulation (Angusta; Norgine BV, Amsterdam) approved for IOL, in France, Belgium, and the Netherlands.

METHODS

A literature review was undertaken to derive probabilities of delivery outcomes (vaginal, instrumental, and cesarean sections) for IOL methods, from published meta-analyses. Outcomes for oral misoprostol tablets (25 µg) were unavailable in the meta-analyses, so were estimated using data from two published retrospective cohort studies. A model was developed to predict the frequency of IOL outcomes and associated costs at the national level, across multiple scenarios. Scenarios were tested using a moderate, medium, and high increase in oral misoprostol tablet (25 µg) uptake. Market shares, costs, and induction rates were defined for each country using multiple data sources.

RESULTS

Increased uptake of oral misoprostol tablets (25 µg) was estimated to be associated with a slightly increased rate of routine vaginal deliveries, and concurrent decreases in instrumental vaginal deliveries and cesarean sections. Since routine vaginal deliveries are less costly than other delivery outcomes, increased uptake of oral misoprostol tablets (25 µg) within the IOL market has the potential to be cost-saving. These trends were predicted using 25 µg oral misoprostol tablet outcomes informed by both retrospective studies.

CONCLUSION

Preliminary outcomes suggest that oral misoprostol tablets at 25 µg per dose may improve outcomes in IOL and be cost-saving. Further study is required to validate these findings and assess the comparative efficacy of IOL methods, including oral misoprostol tablets (25 µg).

Attitudes of pregnant women and healthcare professionals to labour induction and obtaining consent for labour induction

Induction of labour is experienced by up to one third of women and can be a negative experience, in relation to both the decision about whether to have an induction of labour (IoL) and the experience of the process of IoL. This paper reviews the limited evidence of women's views on and experiences of: information provision; shared decision-making; preferences for method and location of IoL; indications for IoL; pain management; and effective communication and support. Healthcare professionals' views are reviewed, but are underrepresented, and further research is needed to understand experiences of gaining consent for IoL. Systematic review evidence is drawn on where possible, but reviews often found small numbers of papers for inclusion, and provide insights rather than conclusive evidence. Future research would benefit from using validated measures to assess the experience of IoL.

Prediction and prevention of stillbirth: dream or reality

PURPOSE OF REVIEW

Stillbirth has a high global prevalence and has not improved despite other advances in maternal and perinatal outcomes in the last 20 years. The global applicability of research is challenged by the fact that most evidence originates from high-income countries, whereas the burden is greatest in low- and middle-income countries. Robust universally applicable evidence is therefore desired to address this problem.

RECENT FINDINGS

Good quality evidence has identified key risk factors for stillbirth. However, an effective universally applicable model is yet to be developed. Published prediction models lack internal or external validation, suffer from the risk of bias or cannot be applied to different populations. Term induction of labour suggests good clinical outcomes with no increase in obstetric interventions but must be considered within the context of the healthcare system's feasibility, cost-effectiveness and the experiences of women.

SUMMARY

The most realistic focus to reduce stillbirth is placental insufficiency. Globally, the greatest benefit will come from treating those with the highest risk of disease, such as those in low and middle-income countries. Further high-quality trials need to be conducted in these settings as a priority.

Outpatient labour induction

The inexorable rise in induction rates over the past two decades, in parallel with increasing medical costs and pressure to reduce length of stay, has led to marked logistic difficulties for health care workers, managers and planners. Maternity services are being overwhelmed by the need to allocate staff and delivery suite space for the scheduling and undertaking of induction processes, rather than focussing care for women in spontaneous labour. Induction of labour according to the majority of current protocols and guidelines necessitates increased length of stay and relatively aggressive use of oxytocin (to reduce the time expended in the labour ward from artificial rupture of membranes (AROM) to establishment of labour). This increased oxytocin usage requires increased use of continuous electronic foetal monitoring, and may also increase epidural usage, further increasing the complexity of labour for the woman and her health care workers. Outpatient care after cervical priming and even outpatient care after AROM may help to ease these pressures and may reduce the medicalisation of the birth experience when induction is indicated, with a potential to reduce oxytocin use and associated interventions. If the period between cervical priming to AROM is managed as outpatient care, then the woman may be able to find better psychological and social support at home, as well as maintain autonomy and get better rest prior to the onset of labour. Inpatient AROM could also be followed by outpatient care until the pregnant person returns to the hospital, either in spontaneous labour, or for initiation of syntocinon after 12-18 h. High-quality research has already demonstrated that outpatient care for cervical ripening is acceptable to mothers and caregivers, has economic benefits and has an acceptable safety profile in appropriately selected low-risk inductions.

Risk of caesarean delivery in labour induction: a systematic review and external validation of predictive models

BACKGROUND

Despite the existence of numerous published models predicting the risk of caesarean delivery in women undergoing induction of labour (IOL), validated models are scarce.

OBJECTIVES

To systematically review and externally assess the predictive capacity of caesarean delivery risk models in women undergoing IOL.

SEARCH STRATEGY

Studies published up to 15 January 2021 were identified through PubMed, CINAHL, Scopus and ClinicalTrials.gov, without temporal or language restrictions.

SELECTION CRITERIA

Studies describing the derivation of new models for predicting the risk of caesarean delivery in labour induction.

DATA COLLECTION AND ANALYSIS

Three authors independently screened the articles and assessed the risk of bias (ROB) according to the prediction model risk of bias assessment tool (PROBAST). External validation was performed in a prospective cohort of 468 pregnancies undergoing IOL from February 2019 to August 2020. The predictive capacity of the models was assessed by creating areas under the receiver operating characteristic curve (AUCs), calibration plots and decision curve analysis (DCA).

MAIN RESULTS

Fifteen studies met the eligibility criteria; 12 predictive models were validated. The quality of most of the included studies was not adequate. The AUC of the models varied from 0.520 to 0.773. The three models with the best discriminative capacity were those of Levine et al. (AUC 0.773, 95% CI 0.720-0.827), Hernández et al. (AUC 0.762, 95% CI 0.715-0.809) and Rossi et al. (AUC 0.752, 95% CI 0.707-0.797).

CONCLUSIONS

Predictive capacity and methodological quality were limited; therefore, we cannot currently recommend the use of any of the models for decision making in clinical practice.

TWEETABLE ABSTRACT

Predictive models that predict the risk of cesarean section in labor inductions are currently not applicable.

An educational video's impact on the induction of labor experience: a randomized controlled trial

BACKGROUND

Induction of labor is a common obstetrical intervention; much research focuses on medical indications, clinical outcomes, and induction agents. Little research has been conducted evaluating the patients' understanding of and satisfaction with induction of labor. Video-based educational tools have been validated as a practical and efficient counseling method by previous studies.

OBJECTIVE

This study aimed to evaluate whether an educational video enhances the patients' knowledge about induction of labor and improves satisfaction with the induction of labor process.

STUDY DESIGN

This was a single-center study in which women undergoing a scheduled induction of labor were randomized to either the control or intervention group. The control group was given a knowledge questionnaire about induction of labor before meeting their provider (midwife or obstetrician) on the day of scheduled induction of labor. The intervention group was shown a 3-minute educational video about induction of labor before administration of the knowledge questionnaire. Both groups, 24 to 48 hours after delivery, were asked to fill out a second questionnaire about satisfaction with the induction of labor process. Moreover, the video intervention group was asked to evaluate the video in the second questionnaire. Both knowledge and satisfaction questionnaires were compared between the control and intervention groups.

RESULTS

From October 2019 to February 2020, 145 women scheduled for induction of labor were eligible and approached for the study. Of the 145 participants, 129 consented and 119 completed the entire study. Moreover, 64 participants were randomized into the control group and 55 into the intervention group. Compared with patients in the control group, the patients who watched the educational video in the intervention group had significantly improved baseline knowledge about induction of labor (P<.001). Knowledge scores remained significantly higher in the intervention group when considering participants who had a previous induction of labor (parity, P<.001; nulliparity, P<.001; multiparity, P<.001). In addition, satisfaction with the induction of labor process among participants in the intervention group was significantly higher than those in the control group (P<.001). Moreover, this held true in those who had a cesarean delivery or had a history of a previous induction of labor (P<.003 and P<.001, respectively).

CONCLUSION

A brief educational video about induction of labor improved the patients' knowledge about the induction of labor process and their overall satisfaction with their delivery experience. Video-based education can play an innovative and important role in patient knowledge and satisfaction with the induction of labor process.

Methods of induction of labor and women's experience: a population-based cohort study with mediation analyses

BACKGROUND

Negative childbirth experience may affect mother wellbeing and health. However, it is rarely evaluated in studies comparing methods of induction of labor (IoL).

AIM

To compare women's experience of IoL according to the method, considering the mediating role of interventions and complications of delivery.

METHODS

We used data from the MEDIP prospective population-based cohort, including all women with IoL during one month in seven French perinatal networks. The experience of IoL, assessed at 2 months postpartum, was first compared between cervical ripening and oxytocin, and secondarily between different cervical ripening methods. Mediation analyses were used to measure the direct and indirect effects of cervical ripening on maternal experience, through delivery with interventions or complications.

FINDINGS

The response rate was 47.8% (n = 1453/3042). Compared with oxytocin (n = 541), cervical ripening (n = 910) was associated less often with feelings that labor went 'as expected' (adjusted risk ratio for the direct effect 0.78, 95%CI [0.70-0.88]), length of labor was 'acceptable' (0.76[0.71-0.82]), 'vaginal discomfort' was absent (0.77[0.69-0.85]) and with lower global satisfaction (0.90[0.84-0.96]). Interventions and complications mediated between 6 and 35% of the total effect of cervical ripening on maternal experience. Compared to the dinoprostone insert, maternal experience was not significantly different with the other prostaglandins. The balloon catheter was associated with less pain.

DISCUSSION

Cervical ripening was associated with a less positive experience of childbirth, whatever the method, only partly explained by interventions and complications of delivery.

CONCLUSION

Counselling and support of women requiring cervical ripening might be enhanced to improve the experience of IoL.

Changes in local protocols on inpatient cervical priming and introduction of outpatient priming: A nationwide survey in the Netherlands

OBJECTIVE

The aims of this study are to assess (changes in) local procedures for inpatient cervical priming as part of induction of labor and to identify the implementation of outpatient cervical priming in the Netherlands.

METHODS

This survey study was conducted from October 2019 until January 2020; obstetricians of all 72 hospitals with a maternity unit in the Netherlands received a questionnaire. The questionnaire consisted of three parts: basic hospital data, local protocol on methods of inpatient induction of labor (IPI), local protocol for outpatient induction of labor (OPI).

RESULTS

A response was received from 66/72 hospitals, giving a response rate of 92%. For IPI the most preferred method was a Foley catheter (87.9%), 27.6% protocols switched to prostaglandins after day 1 if the cervix was not ripe yet. A prostaglandin gel or pessary was not the preferred method on day 1 but only used after 24 h in 5 hospitals (7.6%). OPI was offered in 53% (35/66 hospitals), all using a Foley catheter.

CONCLUSION

In the Netherlands, local protocols for IPI have shifted towards the use of a Foley catheter. More than half of the hospitals offer OPI. As safety and efficacy data of OPI are lacking, research on this topic is urgently warranted.

Intrapartum interventions and outcomes for women and children following induction of labour at term in uncomplicated pregnancies: a 16-year population-based linked data study

OBJECTIVES

We compared intrapartum interventions and outcomes for mothers, neonates and children up to 16 years, for induction of labour (IOL) versus spontaneous labour onset in uncomplicated term pregnancies with live births.

DESIGN

We used population linked data from New South Wales, Australia (2001-2016) for healthy women giving birth at 37+0 to 41+6 weeks. Descriptive statistics and logistic regression were performed for intrapartum interventions, postnatal maternal and neonatal outcomes, and long-term child outcomes adjusted for maternal age, country of birth, socioeconomic status, parity and gestational age.

RESULTS

Of 474 652 included births, 69 397 (15%) had an IOL for non-medical reasons. Primiparous women with IOL versus spontaneous onset differed significantly for: spontaneous vaginal birth (42.7% vs 62.3%), instrumental birth (28.0% vs 23.9%%), intrapartum caesarean section (29.3% vs 13.8%), epidural (71.0% vs 41.3%), episiotomy (41.2% vs 30.5%) and postpartum haemorrhage (2.4% vs 1.5%). There was a similar trend in outcomes for multiparous women, except for caesarean section which was lower (5.3% vs 6.2%). For both groups, third and fourth degree perineal tears were lower overall in the IOL group: primiparous women (4.2% vs 4.9%), multiparous women (0.7% vs 1.2%), though overall vaginal repair was higher (89.3% vs 84.3%). Following induction, incidences of neonatal birth trauma, resuscitation and respiratory disorders were higher, as were admissions to hospital for infections (ear, nose, throat, respiratory and sepsis) up to 16 years. There was no difference in hospitalisation for asthma or eczema, or for neonatal death (0.06% vs 0.08%), or in total deaths up to 16 years.

CONCLUSION

IOL for non-medical reasons was associated with higher birth interventions, particularly in primiparous women, and more adverse maternal, neonatal and child outcomes for most variables assessed. The size of effect varied by parity and gestational age, making these important considerations when informing women about the risks and benefits of IOL.

How is high quality research evidence used in everyday decisions about induction of labour between pregnant women and maternity care professionals? An exploratory study

OBJECTIVE

To explore the use of high quality research evidence in women's and maternity care professionals' decisions about induction of labour (IOL).

METHODS

A qualitative study underpinned by a social constructionist framework, using semi-structured interviews and generative thematic analysis.

SETTING

A large tertiary referral maternity unit in northern England in 2013/14.

PARTICIPANTS

22 randomly selected health care professionals involved in maternity care (midwives, obstetricians, maternity service managers), and 16 postnatal women, 3-8 weeks post-delivery, who were offered IOL in their most recent pregnancy.

FINDINGS

Three themes were identified in the data; (1) the value of different forms of knowledge, (2) accessing and sharing knowledge, and (3) constrained pathways and default choices. Findings echo other evidence in suggesting that women do not feel informed about IOL or that they have choices about the procedure. This study illuminates potential explanatory factors by considering the complex context within which IOL is discussed and offered (e.g. presentation of IOL as routine rather than a choice, care pathways that make declining IOL appear undesirable, blanket use of clinical guidelines without consideration of individual circumstances and preferences).

KEY CONCLUSIONS

This study suggests that organisational, social, and professional factors conspire towards a culture where (a) IOL has become understood as a routine part of maternity care rather than an intervention to make an informed choice about, (b) several factors contribute to demotivate women and health care practitioners from seeking to understand the evidence base regarding induction, and (c) health care professionals can find themselves ill-equipped to discuss the relative risks and benefits of IOL and its alternatives.

IMPLICATIONS FOR PRACTICE

It is important that IOL is recognised as an optional intervention and is not presented to women as a routine part of maternity care. When IOL is offered it should be accompanied by an evidence informed discussion about the options available to support informed decision making. Health care professionals should be supported to understand the evidence base and our findings suggest that any attempt to facilitate this needs to acknowledge and tackle complex organisational, social and professional influences that contribute to current care practices.

Informal coercion during childbirth: risk factors and prevalence estimates from a nationwide survey of women in Switzerland

BACKGROUND

In many countries, the increase in facility births is accompanied by a high rate of obstetric interventions. Lower birthrates or elevated risk factors such as women's higher age at childbirth and an increased need for control and security cannot entirely explain this rise in obstetric interventions. Another possible factor is that women are coerced to agree to interventions, but the prevalence of coercive interventions in Switzerland is unknown.

METHODS

In a nationwide cross-sectional online survey, we assessed the prevalence of informal coercion during childbirth, women's satisfaction with childbirth, and the prevalence of women at risk of postpartum depression. Women aged 18 years or older who had given birth in Switzerland within the previous 12 months were recruited online through Facebook ads or through various offline channels. We used multivariable logistic regression to estimate the risk ratios associated with multiple individual and contextual factors.

RESULTS

In total, 6054 women completed the questionnaire (a dropout rate of 16.2%). An estimated 26.7% of women experienced some form of informal coercion during childbirth. As compared to vaginal delivery, cesarean section (CS) and instrumental vaginal birth were associated with an increased risk of informal coercion (planned CS risk ratio [RR]: 1.52, 95% confidence interval [1.18,1.96]; unplanned CS RR: 1.92 [1.61,2.28]; emergency CS RR: 2.10 [1.71,2.58]; instrumental vaginal birth RR: 2.17 [1.85,2.55]). Additionally, migrant women (RR: 1.45 [1.26,1.66]) and women for whom a self-determined vaginal birth was more important (RR: 1.15 [1.06,1.24]) more often reported informal coercion. Emergency cesarean section (RR: 1.32 [1.08,1.62]), being transferred to hospital (RR: 1.33 [1.11,1.60]), and experiencing informal coercion (RR: 1.35 [1.19,1.54]) were all associated with a higher risk of postpartum depression. Finally, women who had a non-instrumental vaginal birth reported higher satisfaction with childbirth while women who experienced informal coercion reported lower satisfaction.

CONCLUSIONS

One in four women experience informal coercion during childbirth, and this experience is associated with a higher risk of postpartum depression and lower satisfaction with childbirth. To prevent traumatic after-effects, health care professionals should make every effort to prevent informal coercion and to ensure sensitive aftercare for all new mothers.

Cervical ripening at home or in-hospital-prospective cohort study and process evaluation (CHOICE) study: a protocol

INTRODUCTION

The aim of the cervical ripening at home or in-hospital-prospective cohort study and process evaluation (CHOICE) study is to compare home versus in-hospital cervical ripening to determine whether home cervical ripening is safe (for the primary outcome of neonatal unit (NNU) admission), acceptable to women and cost-effective from the perspective of both women and the National Health Service (NHS).

METHODS AND ANALYSIS

We will perform a prospective multicentre observational cohort study with an internal pilot phase. We will obtain data from electronic health records from at least 14 maternity units offering only in-hospital cervical ripening and 12 offering dinoprostone home cervical ripening. We will also conduct a cost-effectiveness analysis and a mixed methods study to evaluate processes and women/partner experiences. Our primary sample size is 8533 women with singleton pregnancies undergoing induction of labour (IOL) at 39+0 weeks' gestation or more. To achieve this and contextualise our findings, we will collect data relating to a cohort of approximately 41 000 women undergoing IOL after 37 weeks. We will use mixed effects logistic regression for the non-inferiority comparison of NNU admission and propensity score matched adjustment to control for treatment indication bias. The economic analysis will be undertaken from the perspective of the NHS and Personal Social Services (PSS) and the pregnant woman. It will include a within-study cost-effectiveness analysis and a lifetime cost-utility analysis to account for any long-term impacts of the cervical ripening strategies. Outcomes will be reported as incremental cost per NNU admission avoided and incremental cost per quality adjusted life year gained.

RESEARCH ETHICS APPROVAL AND DISSEMINATION

CHOICE has been funded and approved by the National Institute of Healthcare Research Health Technology and Assessment, and the results will be disseminated via publication in peer-reviewed journals.

Induction of labour during the COVID-19 pandemic: a national survey of impact on practice in the UK

BACKGROUND

Induction of labour (IOL) is one of the most commonly performed interventions in maternity care, with outpatient cervical ripening increasingly offered as an option for women undergoing IOL. The COVID-19 pandemic has changed the context of practice and the option of returning home for cervical ripening may now assume greater significance. This work aimed to examine whether and how the COVID-19 pandemic has changed practice around IOL in the UK.

METHOD

We used an online questionnaire to survey senior obstetricians and midwives at all 156 UK NHS Trusts and Boards that currently offer maternity services. Responses were analysed to produce descriptive statistics, with free text responses analysed using a conventional content analysis approach.

FINDINGS

Responses were received from 92 of 156 UK Trusts and Boards, a 59% response rate. Many Trusts and Boards reported no change to their IOL practice, however 23% reported change in methods used for cervical ripening; 28% a change in criteria for home cervical ripening; 28% stated that more women were returning home during cervical ripening; and 24% noted changes to women's response to recommendations for IOL. Much of the change was reported as happening in response to attempts to minimise hospital attendance and restrictions on birth partners accompanying women.

CONCLUSIONS

The pandemic has changed practice around induction of labour, although this varied significantly between NHS Trusts and Boards. There is a lack of formal evidence to support decision-making around outpatient cervical ripening: the basis on which changes were implemented and what evidence was used to inform decisions is not clear.

Induction of labor using balloon catheter as an outpatient versus prostaglandin as an inpatient: A cost-effectiveness analysis

OBJECTIVE

The aim of this work was to assess the cost-effectiveness of induction of labor with outpatient balloon catheter cervical priming versus inpatient prostaglandin vaginal gel or tape.

STUDY DESIGN

Economic evaluation alongside a multi-centre, randomized controlled trial at eight Australian maternity hospitals. The trial reported on 448 women with live singleton term pregnancies, undergoing induction of labor for low-risk indications between September 2015 and October 2018. An economic decision tree model was designed from a health services perspective from time of induction of labor to hospital discharge. Sensitivity and subgroup analyses were performed to test the robustness of model outcomes. We estimated resource use, collected data on health outcomes (using EQ-5D-3 L questionnaire) and reported cost (Australian Dollars) per quality-adjusted life year gained, incremental cost-effect ratio and net monetary benefit.

RESULTS

Deterministic analysis showed lower mean costs ($7294 versus $7585) in the outpatient-balloon (n = 205) compared to the inpatient-prostaglandin group (n = 243), with similar health outcomes (0.75 vs 0.74 quality-adjusted life years gained) and overall higher net monetary benefit ($30,054 vs $29,338). In probabilistic analyses outpatient-balloon induction of labor was cost-effective in 55.3 % of all simulations and 59.1 % for women with favourable cervix (modified Bishop score >3) and 64.5 % for nulliparous women.

CONCLUSIONS

Outpatient-balloon induction of labor may be cost-saving compared to inpatient induction of labor with prostaglandin and is most likely to be cost-effective for nulliparous women, but more research is warranted in other settings to explore the generalisability of results.

A systematic review of supportive interventions to promote women's comfort and well-being during induction of labour

AIMS

To evaluate the effectiveness of non-pharmacological non-invasive supportive interventions for impacts on women's comfort and well-being during induction of labour.

DESIGN

A quantitative systematic review without meta-analysis.

DATA SOURCES

Databases were searched for primary research published in English between 2000-2019: AMED, CINAHL, Medline, Maternity and Infant Care database, PsycINFO, and ProQuest. The quality of studies was evaluated using JBI levels of evidence and established critical appraisal tools. Studies describing measures of comfort, coping, and well-being for women during induction of labour were included.

RESULTS

Two articles met the criteria for inclusion. There is limited evidence to suggest that women having outpatient cervical priming were more satisfied with their experience than women having inpatient cervical priming and that outpatient cervical priming did not increase women's anxiety. A specifically designed information brochure explaining the induction process improved women's knowledge and understanding.

REVIEW METHODS

The quantitative systematic review followed the Centre for Reviews and Dissemination guidelines and Cochrane Effective Practice and Organisation of Care guidance. Quality appraisal was conducted using JBI levels of evidence, Cochrane Risk of Bias, and other established tools. A narrative description of the quantitative data was undertaken. There was insufficient evidence to perform a narrative synthesis or meta-analysis due to the nature of the study designs and insufficient outcome data.

CONCLUSIONS

Globally, the number of women having an induction of labour is increasing and there is a lack of evidence on the effectiveness of supportive interventions. Components of supportive care for women having induction of labour require urgent evaluation. Measurement tools which capture the complexity of supportive care for women having induction of labour need to be developed and validated.

IMPACT

This is the first review to evaluate non-pharmacological, non-invasive supportive interventions for women having induction of labour. The findings of this review identify the urgent need to develop an evidence base for effective supportive.
