Abstract
INTRODUCTION Achieving the Sustainable Development Goals to reduce maternal and neonatal mortality rates will require the expansion and strengthening of quality maternal health services. Midwife-led birth centres (MLBCs) are an alternative to hospital-based care for low-risk pregnancies where the lead professional at the time of birth is a trained midwife. These have been used in many countries to improve birth outcomes. METHODS The cost analysis used primary data collection from four MLBCs in Bangladesh, Pakistan and Uganda (n=12 MLBC sites). Modelled cost-effectiveness analysis was conducted to compare the incremental cost-effectiveness ratio (ICER), measured as incremental cost per disability-adjusted life-year (DALY) averted, of MLBCs to standard care in each country. Results were presented in 2022 US dollars. RESULTS Cost per birth in MLBCs varied greatly within and between countries, from US$21 per birth at site 3, Bangladesh to US$2374 at site 2, Uganda. Midwife salary and facility operation costs were the primary drivers of costs in most MLBCs. Six of the 12 MLBCs produced better health outcomes at a lower cost (dominated) compared with standard care; and three produced better health outcomes at a higher cost compared with standard care, with ICERs ranging from US$571/DALY averted to US$55 942/DALY averted. CONCLUSION MLBCs appear to be able to produce better health outcomes at lower cost or be highly cost-effective compared with standard care. Costs do vary across sites and settings, and so further exploration of costs and cost-effectiveness as a part of implementation and establishment activities should be a priority.

Satisfaction and Dissatisfaction With Pain Relief and Birth Experience Among Induced and Spontaneous-onset Labours Ending in Vaginal Birth: A Prospective Cohort Study. Eur J Obstet Gynecol Reprod Biol X 2023; 18:100185. [PMID: 37035413 PMCID: PMC10073637 DOI: 10.1016/j.eurox.2023.100185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 02/10/2023] [Accepted: 03/15/2023] [Indexed: 03/18/2023] Open
Abstract
Objective To assess pain relief and overall birth experience in induced vs. spontaneous-onset labours and to clarify variables among induced parturients determining satisfaction and dissatisfaction. Study design A prospective study of 2042 women. 575 women with induced and 1467 with spontaneous-onset labour answered multiple questions in a questionnaire regarding the experience of birth giving. Satisfaction was numerically assessed via a visual analogue scale (VAS 0-10). Results Induction of labour (IOL) did not worsen the average experience of pain relief, but the proportion of women dissatisfied with pain relief was slightly higher after IOL compared with spontaneous-onset labour (SOL). IOL was associated with lower satisfaction with overall birth experience compared with SOL (VAS 8.0 vs. 8.4; p < 0.001). Among IOL parturients incorrect timing of pain relief was strongly associated with dissatisfaction with pain relief, as were deficient information and induction with misoprostol. Epidural blockade was the most important factor preventing dissatisfaction with pain relief. Unsatisfactory overall experience of birth was associated with deficient pain relief, its incorrect timing or deficient information, as well as vacuum extraction as the mode of delivery. Conclusions Induction of labour is a risk factor of dissatisfaction regarding pain relief and overall birth experience. The strongest impact on dissatisfaction among induced parturients concerning pain relief was delayed timing of effective labour analgesia. Poor pain relief, its incorrect timing and deficient information on pain relief were strong predictive factors of dissatisfaction with the overall birth experience.

Abstract
OBJECTIVES Delay in the induction of labour (IOL) process is associated with poor patient experience and adverse perinatal outcome. Our objective was to identify factors associated with delay in the IOL process and develop interventions to reduce delay. DESIGN AND SETTINGS We performed a retrospective cohort study of maternity unit workload in a large UK district general hospital. Electronic hospital records were used to quantify delay in the IOL process and linear regression analysis was performed to assess significant associations between delay and potential causative factors. A novel computer maternity unit simulation model, MUMSIM (Maternity Unit Management SIMulation), was developed using real-world data and interventions were tested to identify those associated with a reduction in delay. PARTICIPANTS All women giving birth at Stoke Mandeville Hospital, Buckinghamshire National Health Service (NHS) Trust in 2018 (n=4932). PRIMARY OUTCOME MEASURE Delay in the IOL process of more than 12 hours. RESULTS The retrospective analysis of real-world maternity unit workload showed 30% of women had IOL and of these, 33% were delayed >12 hours with 20% delayed >24 hours, 10% delayed >48 hours and 1.3% delayed >72 hours. Delay was significantly associated with the total number of labouring women (p=0.008) and the number of booked IOL (p=0.009) but not emergency IOL, spontaneously labouring women or staffing shortfall. The MUMSIM computer simulation predicted that changing from slow release 24-hour prostaglandin to 6-hour prostaglandin for primiparous women would reduce delay by 4% (p<0.0001) and that additional staffing interventions could significantly reduce delay up to 17.9% (p<0.0001). CONCLUSIONS Planned obstetric workload of booked IOL is associated with delay rather than the unpredictable workload of women in spontaneous labour or emergency IOL. We present a novel maternity unit computer simulation model, MUMSIM, which allows prediction of the impact of interventions to reduce delay.

Abstract
BACKGROUND In many well-resourced countries, rising rates of intervention are being observed during pregnancy, labour and childbirth with induction of labour (IOL) fast becoming one of the most common. In Australia, the rate of induction of labour has increased by over 30% since 2007, and today one in three women have their labours induced. We do not however have a good understanding of the contribution of specific obstetric populations to this trend. METHODS We examine the contribution of specific obstetric populations to induction of labour over a six-year period at one tertiary maternity service, using the Nippita classification system. Average Annual Percentage Changes (AAPC) were calculated along with 95% confidence intervals and P values set at 0.05. RESULTS The overall rate of induction of labour increased from 21.3% in 2012 to 30.9% in 2017, representing an Average Annual Percent Change of 8.1, P<0.0001 (95% CI 7-9.6). The greatest AAPC was seen in group 5 (parous, no previous caesarean section, 39-40 weeks, single cephalic), followed by group 2 (nulliparous, 39-40 weeks, single cephalic) and 1 (nulliparous, 37-38 weeks, single cephalic). CONCLUSIONS The use of the Nippita classification system allowed for standardised comparison across timepoints, facilitating identification of the subpopulations driving changes in rates of induction of labour. Rates of induction of labour saw a year on year increase which in this maternity service, it is not being driven by post-dates pregnancies. Further work is required to understand the role of other potential contributors such as diabetes.

Abstract
BACKGROUND How the application of evidence to planned birth practices, induction of labour (IOL) and prelabour caesarean (CS), differs between Australian maternity units remains poorly understood. Perceptions of readiness for practice change and resources to implement change in individual units are also unclear. AIM To identify inter-hospital and inter-professional variations in relation to current planned birth practices and readiness for change, reported by clinicians in 7 maternity units. METHOD Custom-created survey of maternity staff at 7 Sydney hospitals, with questions about women's engagement with decision making, indications for planned birth, timing of birth and readiness for change. Responses from midwives and medical staff, and from each hospital, were compared. FINDINGS Of 245 completed surveys (27% response rate), 78% were midwives and 22% medical staff. Substantial inter-hospital variation was noted for stated planned birth indication, timing, women's involvement in decision-making practices, as well as in staff perceptions of their unit's readiness for change. Overall, 48% (range 31-64%) and 64% (range 39-89%) agreed on a need to change their unit's caesarean and induction practices respectively. The three units where greatest need for change was perceived also had least readiness for change in terms of leadership, culture, and resources. Regarding inter-disciplinary variation, medical staff were more likely than midwifery staff to believe women were appropriately informed and less likely to believe unit practice change was required. CONCLUSION Planned birth practices and change readiness varied between participating hospitals and professional groups. Hospitals with greatest perceived need for change perceived least resources to implement such change.

Abstract
OBJECTIVE Variation in practice in relation to indications and timing for both induction of labour (IOL) and planned caesarean section (CS) clearly exists. However, the extent of this variation, and how this variation is explained by clinicians remains unclear. The aim of this study was to map the variation in IOL and planned CS at eight Australian hospitals, and understand why variation occurs from the perspective of clinicians at these hospitals. Our ultimate aim was to identify opportunities for improvement as evidenced by hospital data, clinician experiences, and feedback. DESIGN A two-phased mixed method study using sequential explanatory study design. The first phase consisted of an analysis of routinely collected patient data to map variation between hospitals. The second phase consisted of focus groups with clinicians to gain their perspectives on the reasons for variation. SETTING AND PARTICIPANTS Patient data consisted of routine data from 19,073 women giving birth at eight Sydney hospitals between November 2017 and October 2018. Focus groups were attended by a total of 61 medical staff and 121 midwives. RESULTS Hospital data analysis found substantial variation, before and after adjustment for case-mix, in rates of both IOL (adjusted rates 27.6%-42%) and planned CS (adjusted rate 15.4%-22.6%). Planned CS by gestation also showed variation, although after restricting analysis to term (≥37 weeks gestation) births, variation was reduced. At focus groups, five main themes explaining variation emerged: local guidelines, policies and procedures (inconsistency and ambiguity); uncertainty of the evidence/what is best practice (contradictory research and different interpretations of evidence); clinician preferences, beliefs and values; the culture of the unit; and organisational influences (access to specialised clinics, theatre time). KEY CONCLUSIONS Considerable variation in IOL and planned CS, even after case-mix adjustment, was found in this sample of Australian hospitals. Engagement with hospital clinicians identified likely sources of this variation and enabled clinicians at each hospital to consider appropriate local responses to address variation, such as more detailed review of their planned birth cases. IMPLICATIONS FOR PRACTICE At a macro level, measures to reduce unwarranted variation should initially focus on consistent national guidelines, while supporting equitable access to operating theatres for optimal CS timing, and shared decision-making training to reduce influence of clinician preference.

Abstract
AIM This study aimed to investigate the effects of the interventions in the delivery room on the delivery process and the newborn health. METHOD The analytical-cross-sectional study was carried out with 354 puerperal women who gave birth in hospital between December 2016 and June 2017 in a public hospital. The data were collected by the data collection form developed by the researchers. Data analysis was done by using descriptive statistics and chi-square test in SPSS 21.00 program. RESULTS The interventions were determined in continuous electro fetal monitoring (80.5%), oxytocin induction (79.9%), restriction of free movement (56.8%), amniotomy (49.7%), enema (44.1%), and movement restriction (56.8%). The intervention period of the second phase of delivery was longer and the rate of cesarean section was higher, and the need for NICU, suction difficulty, 5th APGAR score less than 7, trauma development, difficulty in suction, and higher trauma rates were found in infants. It was determined that the rate of oxygen need in puerperals admitted to the delivery room with cervical dilatation below five cm, vacuum and episiotomy applications in those who underwent amniotomy, and vacuum application rates in those undergoing oxytocin inductions were found to be high. In addition, the rate of fundal compression and episiotomy was significantly higher in patients who used continuous electro fetal monitoring, fundal compression and vacuum rate in patients who were administered analgesic drugs, and episiotomy rates in patients using analgesic drugs. CONCLUSION It has been concluded that interventions in the first phase of labor negatively affect the delivery process and neonatal health and increase the need for intervention in the second phase.

Abstract
BACKGROUND Concerns have been raised that synthetic oxytocin, a widely used obstetric tool for labor induction and augmentation, may have deleterious effects on the neuropsychological development of children. Few studies have examined the relationship between oxytocin-stimulated labor and emotional disorders. METHODS We conducted a nationwide register-based cohort study including 677,629 singletons born in Denmark in the years 2000 to 2012 and followed through 2016 (median age = 10.6 years). Data on oxytocin-stimulation were obtained from the Danish Medical Birth Register. Cases of emotional disorders - anxiety, obsessive-compulsive disorder, mood or traumatic stress disorders or a redeemed prescription for a selective serotonin reuptake inhibitor - were identified using Danish patient and prescription registries. RESULTS Oxytocin was used to stimulate 31% of births, and oxytocin-stimulated labor was not associated with childhood emotional disorders (HR = 1.05, 95% CI 0.99, 1.11) after adjustment for maternal history of psychopathology, antidepressants during pregnancy, cohabitation status, highest educational attainment, smoking status during pregnancy, birth year, and indications for labor stimulation. The crude cox model was also small and close to unity (HR = 1.09, 95% CI 1.03, 1.15). LIMITATIONS About 50% of our population had reached the age of 10 years, but the outcome included disorders with later average debut ages. Oxytocin dosage levels are not recorded in the registers. CONCLUSIONS Our small effect size estimates suggest that perinatal synthetic oxytocin does not contribute to the development of emotional disorders. Current evidence does not warrant revision of guidelines for the use of oxytocin in obstetrics.

Exploring unwarranted clinical variation: The attitudes of midwives and obstetric medical staff regarding induction of labour and planned caesarean section. Women Birth 2020; 34:352-361.

Abstract
BACKGROUND Unexplained clinical variation is a major issue in planned birth i.e. induction of labour and planned caesarean section. AIM To map attitudes and knowledge of maternity care professionals regarding indications for planned birth, and assess inter-professional (midwifery versus medical) and intra-professional variation. METHODS A custom-created survey of medical and midwifery staff at eight Sydney hospitals. Staff were asked to rate their level of agreement with 45 "evidence-based" statements regarding caesareans and inductions on a five-point Likert scale. Responses were grouped by profession, and comparisons made of inter- and intra-professional responses. FINDINGS Total 275 respondents, 78% midwifery and 21% medical. Considerable inter- and intra-professional variation was noted, with midwives generally less likely to consider any of the planned birth indications "valid" compared to medical staff. Indications for induction with most variation in midwifery responses included maternal characteristics (age≥40, obesity, ethnicity) and fetal macrosomia; and for medical personnel in-vitro fertilisation, maternal request, and routine induction at 39 weeks gestation. Indications for caesarean with most variation in midwifery responses included previous lower segment caesarean section, previous shoulder dystocia, and uncomplicated breech; and for medical personnel uncomplicated dichorionic twins. Indications with most inter-professional variation were induction at 41+ weeks versus 42+ weeks and cesarean for previous lower segment caesarean section. DISCUSSION Both inter- and intra-professional variation in what were considered valid indications reflected inconsistency in underlying evidence and/or guidelines. CONCLUSION Greater focus on interdisciplinary education and consensus, as well as on shared decision-making with women, may be helpful in resolving these tensions.

Abstract
Background Labour induction is a childbirth intervention experienced by a growing number of women globally each year. While the maternal and socioeconomic indicators of labour induction are well documented in countries like the United States, considerably less research has been done into which women have a higher likelihood of labour induction in the United Kingdom. This paper explores the relationship between labour induction and maternal demographic, socioeconomic, and health indicators by parity in the United Kingdom. Method Logistic regression analyses were conducted using the first sweep of the Millennium Cohort Study, including a wide range of socioeconomic factors such as maternal educational attainment, marital status, and electoral ward deprivation, in addition to maternal and infant health indicators. Results In fully adjusted models, nulliparous and multiparous women with fewer educational qualifications and those living in disadvantaged places had a greater likelihood of labour induction than women with higher qualifications and women in advantaged electoral wards. Conclusions This paper highlights which UK women are at higher risk of labour induction and how this risk varies by socioeconomic status, demonstrating that less advantaged women are more likely to experience labour induction. This evidence could help health care professionals identify which patients may be at higher risk of childbirth intervention.

Abstract
Background: Twin pregnancy is associated with a threefold increase in perinatal death compared to singletons. The objective of this study was to determine the risk of perinatal death in twins by week of gestation and to quantify the effect of known risk factors. Methods: A cohort analysis was performed using data from the Aberdeen Maternity and Neonatal Databank (AMND). The exposure was gestational age at delivery and the primary outcome was perinatal death. Adjusted hazard ratios (aHRs) for perinatal death according to gestational age at delivery were determined by multivariate Cox proportional hazards regression modelling with robust standard errors to account for clustering in the twin infants. Confounders and risk factors quantified and adjusted for in the model included maternal age, smoking, parity, marital status and year of birth. Kaplan-Meier time to event analysis was used to determine the differences in survival according to chorionicity and assisted reproduction technologies (ART) conception status. Results: The population comprised of 7,420 twin babies born between 1950 and 2013 in the Grampian area of Northern Scotland. There were 272 stillbirths in the cohort (3.67%) and 273 neonatal deaths (3.68%). Compared to delivery at 37-38 weeks, delivery before 37 weeks was associated with a 2-fold increase in perinatal death. Monochorionic twins had a 2-fold increase in perinatal death compared to dichorionic twins (aHR 2.15, 95% CI 1.60-2.90). Twins conceived by ART did not have a greater risk of perinatal death compared to those naturally conceived (aHR 1.21, 95% CI 0.87-1.68) Conclusion: This study suggests that delivery of twins at 37-38 weeks is associated with the lowest risk of perinatal death.

Induction of labour indications and timing: A systematic analysis of clinical guidelines. Women Birth 2019; 33:219-230. [PMID: 31285166 DOI: 10.1016/j.wombi.2019.06.004] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 06/04/2019] [Accepted: 06/05/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND There is widespread and some unexplained variation in induction of labour rates between hospitals. Some practice variation may stem from variability in clinical guidelines. This review aimed to identify to what extent induction of labour guidelines provide consistent recommendations in relation to reasons for, and timing of, induction of labour and ascertain whether inconsistencies can be explained by variability guideline quality. METHOD We conducted a systematic search of national and international English-language guidelines published between 2008 and 2018. General induction of labour guidelines and condition-specific guidelines containing induction of labour recommendations were searched. Guidelines were reviewed and extracted independently by two reviewers. Guideline quality was assessed using the Appraisal of Guidelines for Research and Evaluation II Instrument. FINDINGS Forty nine guidelines of varying quality were included. Indications where guidelines had mostly consistent advice included prolonged pregnancy (induction between 41 and 42 weeks), preterm premature rupture of membranes, and term preeclampsia (induction when preeclampsia diagnosed ≥37 weeks). Guidelines were also consistent in agreeing on decreased fetal movements and oligohydramnios as valid indications for induction, although timing recommendations were absent or inconsistent. Common indications where there was little consensus on validity and/or timing of induction included gestational diabetes, fetal macrosomia, elevated maternal body mass index, and twin pregnancy. CONCLUSION Substantial variation in clinical practice guidelines for indications for induction exists. As guidelines rated of similar quality presented conflicting recommendations, guideline variability was not explained by guideline quality. Guideline variability may partly account for unexplained variation in induction of labour rates.

Induction of labour: Experiences of care and decision-making of women and clinicians. Women Birth 2019; 33:e1-e14.

Abstract
BACKGROUND There has been a rise in induction of labour over recent decades. There is some tension in the literature in relation to when induction is warranted and when not, with variability between guidelines and practice. Given these tensions, the importance of shared decision-making between clinicians and women is increasingly highlighted as paramount, but it remains unclear to what extent this occurs in routine care. METHOD Using a scoping review methodology, quantitative and qualitative evidence were considered to answer the research question "What are the views, preferences and experiences of women and clinicians in relation to induction of labour more broadly, and practices of decision-making specifically?" To identify studies, the databases PubMed, Maternity and Infant Care, CINAHL and EMBASE were searched from 2008 to 2018, and reference lists of included studies were examined. FINDINGS 20 papers met inclusion criteria, in relation to (a) women's preferences, experiences and satisfaction with IOL; (b) women's experience of shared-decision making in relation to induction; (c) interventions that improve shared decision-making and (d) factors that influence decision-making from the perspective of clinicians. Synthesis of the included studies indicates that decision-making in relation to induction of labour is largely informed by medical considerations. Women are not routinely engaged in the decision making process with expectations and preferences largely unmet. CONCLUSION There is a need to develop strategies such as decision aids, the redesign of antenatal classes, and clinician communication training to improve the quality of information available to women and their capacity for informed decision-making.

Abstract
Propensity score matching (PSM) and propensity score weighting (PSW) are popular tools to estimate causal effects in observational studies. We address two open issues: how to estimate propensity scores and assess covariate balance. Using simulations, we compare the performance of PSM and PSW based on logistic regression and machine learning algorithms (CART; Bagging; Boosting; Random Forest; Neural Networks; naive Bayes). Additionally, we consider several measures of covariate balance (Absolute Standardized Average Mean (ASAM) with and without interactions; measures based on the quantile-quantile plots; ratio between variances of propensity scores; area under the curve (AUC)) and assess their ability in predicting the bias of PSM and PSW estimators. We also investigate the importance of tuning of machine learning parameters in the context of propensity score methods. Two simulation designs are employed. In the first, the generating processes are inspired to birth register data used to assess the effect of labor induction on the occurrence of caesarean section. The second exploits more general generating mechanisms. Overall, among the different techniques, random forests performed the best, especially in PSW. Logistic regression and neural networks also showed an excellent performance similar to that of random forests. As for covariate balance, the simplest and commonly used metric, the ASAM, showed a strong correlation with the bias of causal effects estimators. Our findings suggest that researchers should aim at obtaining an ASAM lower than 10% for as many variables as possible. In the empirical study we found that labor induction had a small and not statistically significant impact on caesarean section.

Abstract
Uterine tachysystole (TS) is a potentially significant intrapartum complication seen most commonly in induced or augmented labors but may also occur in women with spontaneous labor. When it occurs, maternal and perinatal complications can arise if not identified and managed promptly by obstetric care providers. Over recent years, new definitions of the condition have facilitated further research into the field, which has been synthesized to inform clinical management guidelines and protocols. We propose a set of recommendations pertaining to TS in line with contemporary evidence and obstetric practice.

Abstract
Being pregnant beyond one’s estimated due date is a relatively common experience and requires complex decisions about whether to induce labour or wait for spontaneous onset. We report a qualitative study undertaken in the UK in 2016. We interviewed fifteen women and eleven more took part in an online focus group. Using thematic analysis, resistance to the medicalisation of prolonged pregnancy was identified as a strong theme. Drawing on the work of Armstrong and Murphy, we identify both conceptual and behavioural resistance in the accounts of women who accepted, delayed or declined induction of labour. Experiential knowledge played a key role in resistance, but women found this was devalued. Some healthcare staff used risk discourse to pressure women to comply with induction protocols but were unwilling to engage in discussion. The social context provided further pressure to produce a baby ‘on time’, with induction normalised as the way to manage prolonged pregnancy. Online spaces provided additional information and support for women to question the medicalisation of prolonged pregnancy. We end by considering the implications for policies of choice and agency in maternity care as well as the need for additional social support for women who are ‘overdue’.

Abstract
BACKGROUND In response to rising rates of medical intervention in birth, there has been increased international interest in promoting normal birth (without induction of labour, epidural/spinal/general anaesthesia, episiotomy, forceps/vacuum, or caesarean section). However, there is limited evidence for how best to achieve increased rates of normal birth. In this study we examined the role of modifiable and non-modifiable factors in experiencing a normal birth using retrospective, self-reported data. METHODS Women who gave birth over a four-month period in Queensland, Australia, were invited to complete a questionnaire about their preferences for and experiences of pregnancy, labour, birth, and postnatal care. Responses (N = 5840) were analysed using multiple logistic regression models to identify associations with four aspects of normal birth: onset of labour, use of anaesthesia, mode of birth, and use of episiotomy. The probability of normal birth was then estimated by combining these models. RESULTS Overall, 28.7% of women experienced a normal birth. Probability of a normal birth was reduced for women who were primiparous, had a history of caesarean, had a multiple pregnancy, were older, had a more advanced gestational age, experienced pregnancy-related health conditions (gestational diabetes, low-lying placenta, high blood pressure), had continuous electronic fetal monitoring during labour, and knew only some of their care providers for labour and birth. Women had a higher probability of normal birth if they lived outside major metropolitan areas, did not receive private obstetric care, had freedom of movement throughout labour, received continuity of care in labour and birth, did not have an augmented labour, or gave birth in a non-supine position. CONCLUSIONS Our findings highlight several relevant modifiable factors including mobility, monitoring, and care provision during labour and birth, for increasing normal birth opportunity. An important step forward in promoting normal birth is increasing awareness of such relationships through patient involvement in informed decision-making and implementation of this evidence in care guidelines.

Abstract
The last half century has seen significant changes to Maternity services in England. Though rates of maternal and infant mortality have fallen to very low levels, this has been achieved largely through hospital admission. It has been argued that maternity services may have become over-medicalised and service users have expressed a preference for more personalised care. NHS England's national strategy sets out a vision for a modern maternity service that continues to deliver safe care whilst also adopting the principles of personalisation. Therefore, there is a need to develop maternity services that balance safety with personal choice. To address this challenge, a maternity unit in North East England considered improving their service through refurbishment or building new facilities. Using a design process known as the production preparation process (or 3P), the Lean principles of understanding user value, mapping value-streams, creating flow, developing pull processes and continuous improvement were applied to the design of a new maternity department. Multiple stakeholders were engaged in the design through participation in a time-out (3P) workshop in which an innovative pathway and facility for maternity services were co-designed. The team created a hybrid model that they described as “wrap around care” in which the Lean concept of pull was applied to create a service and facility design in which expectant mothers were put at the centre of care with clinicians, skills, equipment and supplies drawn towards them in line with acuity changes as needed. Applying the Lean principles using the 3P method helped stakeholders to create an innovative design in line with the aspirations and objectives of the National Maternity Review. The case provides a practical example of stakeholders applying the Lean principles to maternity services and demonstrates the potential applicability of the Lean 3P approach to design healthcare services in line with policy requirements.

Abstract
BACKGROUND In developed countries, rates of induction of labour (IOL) have increased and vary between hospitals. We aimed to identify whether national variations could be explained by sociodemographic, clinical and organisational differences. METHODS Two national databases in Ireland that routinely collect clinical and administrative data, the National Perinatal Reporting System and the Hospital Inpatient Enquiry Scheme, were used to analyse data for all women with singleton births weighing ≥500 g in 2009. We used logistic multilevel models to examine variation between hospitals, and to determine how much variation was due to individual level sociodemographic, clinical and organisational variables. Analyses were stratified for nulliparas, multiparas without prior caesarean section (CS) and multiparas with prior CS. RESULTS Of 69 304 eligible births, the rate of IOL nationally was 25.0% (range 14.5-33.2%).In nulliparas, the mean rate was 30.9% (range 18.6-45.7%). The rate was 24.8% (13.5-33.3%) and 3.8% (0.0-10.2%) for multiparas without and with prior CS, respectively. In nulliparas and multiparas without prior CS IOL was predicted by maternal birth in Ireland, increasing birthweight, antepartum complications, giving birth on a weekday and the model of obstetric care. Even after adjusting for known sociodemographic and clinical variables, variation between hospitals remained. CONCLUSION We found that clinical, sociodemographic and organisational factors all contributed to variation. However, unexplained variation persisted possibly due to organisational factors such as hospital-specific policies on IOL. The results indicate that the prevalence of antenatal complications, changing immigration patterns and policies on IOL after previous CS are factors likely to influence future IOL rates.

Abstract
BackgroundStudies of maternal mortality have been shown to result in important improvements to women’s health. It is now recognised that in countries such as the UK, where maternal deaths are rare, the study of near-miss severe maternal morbidity provides additional information to aid disease prevention, treatment and service provision.ObjectivesTo (1) estimate the incidence of specific near-miss morbidities; (2) assess the contribution of existing risk factors to incidence; (3) describe different interventions and their impact on outcomes and costs; (4) identify any groups in which outcomes differ; (5) investigate factors associated with maternal death; (6) compare an external confidential enquiry or a local review approach for investigating quality of care for affected women; and (7) assess the longer-term impacts.MethodsMixed quantitative and qualitative methods including primary national observational studies, database analyses, surveys and case studies overseen by a user advisory group.SettingMaternity units in all four countries of the UK.ParticipantsWomen with near-miss maternal morbidities, their partners and comparison women without severe morbidity.Main outcome measuresThe incidence, risk factors, management and outcomes of uterine rupture, placenta accreta, haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome, severe sepsis, amniotic fluid embolism and pregnancy at advanced maternal age (≥ 48 years at completion of pregnancy); factors associated with progression from severe morbidity to death; associations between severe maternal morbidity and ethnicity and socioeconomic status; lessons for care identified by local and external review; economic evaluation of interventions for management of postpartum haemorrhage (PPH); women’s experiences of near-miss maternal morbidity; long-term outcomes; and models of maternity care commissioned through experience-led and standard approaches.ResultsWomen and their partners reported long-term impacts of near-miss maternal morbidities on their physical and mental health. Older maternal age and caesarean delivery are associated with severe maternal morbidity in both current and future pregnancies. Antibiotic prescription for pregnant or postpartum women with suspected infection does not necessarily prevent progression to severe sepsis, which may be rapidly progressive. Delay in delivery, of up to 48 hours, may be safely undertaken in women with HELLP syndrome in whom there is no fetal compromise. Uterine compression sutures are a cost-effective second-line therapy for PPH. Medical comorbidities are associated with a fivefold increase in the odds of maternal death from direct pregnancy complications. External reviews identified more specific clinical messages for care than local reviews. Experience-led commissioning may be used as a way to commission maternity services.LimitationsThis programme used observational studies, some with limited sample size, and the possibility of uncontrolled confounding cannot be excluded.ConclusionsImplementation of the findings of this research could prevent both future severe pregnancy complications as well as improving the outcome of pregnancy for women. One of the clearest findings relates to the population of women with other medical and mental health problems in pregnancy and their risk of severe morbidity. Further research into models of pre-pregnancy, pregnancy and postnatal care is clearly needed.FundingThe National Institute for Health Research Programme Grants for Applied Research programme.

A retrospective population-based study of induction of labour trends and associated factors among aboriginal and non-aboriginal mothers in the northern territory between 2001 and 2012. BMC Pregnancy Childbirth 2016; 16:126. [PMID: 27245447 PMCID: PMC4888469 DOI: 10.1186/s12884-016-0899-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2015] [Accepted: 05/10/2016] [Indexed: 11/10/2022] Open
Abstract
Background Induction of labour (IOL) has become more common among many populations, but the trends and drivers of IOL in the Northern Territory (NT) of Australia are not known. This study investigated trends in IOL and associated factors among NT Aboriginal and non-Aboriginal mothers between 2001 and 2012. Methods A retrospective analysis of all NT resident women who birthed in the NT between 2001 and 2012 at ≥32 weeks gestation. Demographic, medical and obstetric data were obtained from the NT Midwives’ Collection. The prevalence of IOL was calculated by Aboriginal status and parity of the mother and year of birth. The prevalence of each main indication for induction among women was compared for 2001–2003 and 2010–2012. Linear and logistic regression was used to test for association between predictive factors and IOL in bivariate and multivariate analysis, separately for Aboriginal and non-Aboriginal mothers. Results A total of 42,765 eligible births between 2001 and 2012 were included. IOL was less common for Aboriginal than non-Aboriginal mothers in 2001 (18.0 % and 25.1 %, respectively), but increased to be similar to non-Aboriginal mothers in 2012 (22.6 % and 24.8 %, respectively). Aboriginal primiparous mothers demonstrated the greatest increase in IOL. The most common indication for IOL for both groups was post-dates, which changed little over time. Medical and obstetric complications were more common for Aboriginal mothers except late-term pregnancy. Prevalence of diabetes in pregnancy increased considerably among both Aboriginal and non-Aboriginal mothers, but was responsible for only a small proportion of IOLs. Increasing prevalence of risk factors did not explain the increased IOL prevalence for Aboriginal mothers. Conclusions IOL is now as common for Aboriginal as non-Aboriginal mothers, though their demographic, medical and obstetric profiles are markedly different. Medical indications did not explain the recent increase in IOL among Aboriginal mothers; changes in maternal or clinical decision-making may have been involved.

Back to normal: A retrospective, cross-sectional study of the multi-factorial determinants of normal birth in Queensland, Australia. Midwifery 2015; 31:818-27. [PMID: 25921954 DOI: 10.1016/j.midw.2015.04.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2014] [Revised: 02/24/2015] [Accepted: 04/07/2015] [Indexed: 11/21/2022]
Abstract
BACKGROUND currently, care providers and policy-makers internationally are working to promote normal birth. In Australia, such initiatives are being implemented without any evidence of the prevalence or determinants of normal birth as a multidimensional construct. This study aimed to better understand the determinants of normal birth (defined as without induction of labour, epidural/spinal/general anaesthesia, forceps/vacuum, caesarean birth, or episiotomy) using secondary analyses of data from a population survey of women in Queensland, Australia. METHODS women who birthed in Queensland during a two-week period in 2009 were mailed a survey approximately three months after birth. Women (n=772) provided retrospective data on their pregnancy, labour and birth preferences and experiences, socio-demographic characteristics, and reproductive history. A series of logistic regressions were conducted to determine factors associated with having labour, having a vaginal birth, and having a normal birth. FINDINGS overall, 81.9% of women had labour, 66.4% had a vaginal birth, and 29.6% had a normal birth. After adjusting for other significant factors, women had significantly higher odds of having labour if they birthed in a public hospital and had a pre-existing preference for a vaginal birth. Of women who had labour, 80.8% had a vaginal birth. Women who had labour had significantly higher odds of having a vaginal birth if they attended antenatal classes, did not have continuous fetal monitoring, felt able to 'take their time' in labour, and had a pre-existing preference for a vaginal birth. Of women who had a vaginal birth, 44.7% had a normal birth. Women who had a vaginal birth had significantly higher odds of having a normal birth if they birthed in a public hospital, birthed outside regular business hours, had mobility in labour, did not have continuous fetal monitoring, and were non-supine during birth. CONCLUSIONS these findings provide a strong foundation on which to base resources aimed at increasing informed decision-making for maternity care consumers, providers, and policy-makers alike. Research to evaluate the impact of modifying key clinical practices (e.g., supporting women׳s mobility during labour, facilitating non-supine positioning during birth) on the likelihood of a normal birth is an important next step.

Abstract
OBJECTIVE to evaluate a change of guideline for earlier induction of labour in post term pregnancies and its possible impact on selected birth interventions and outcome of the newborn. DESIGN a historical cohort study. SETTINGS Department of Obstetrics at Aarhus University Hospital in Denmark. PARTICIPANTS 18,247 women giving birth between 1 January 2009 and 12 December 2012. METHODS to compare induction of labour in two consecutive time periods before and after implementation of a new guideline on induction of labour (42 weeks versus 41 weeks plus five days gestational age) in post term pregnancy. t-Test and χ(2) were used to calculate means of gestational age and relative risk (RR) of selected birth and newborn outcomes. Stratification by Mantel-Haenszel-analysis was used to adjust for possible confounders. Robson׳s classification system 'Ten Group Classification System' was used to create comparable groups within the performed analysis. FINDINGS a difference in means of three gestational days after implementation of the new guideline on earlier induction of labour was found together with an overall unadjusted decrease in emergency caesarean section rate of 30% (RR 0.70, 95% CI; 0.54-0.91). Stratified analysis on parity showed a reduction in emergency caesarean section but only in nulliparous women (RR 0.78, 95% CI; 0.66-0.92), whereas the analysis in multiparous women showed a non-statistically significant increased risk of emergency caesarean section (RR 1.39, 95% CI; 0.89-2.18). No differences were found in assisted vaginal childbirths and outcome in newborns concerning Apgar score, pH and standard base excess in women induced in 42 weeks versus 41 weeks plus five days gestational age. CONCLUSION the findings of this study suggest that earlier induction of labour due to post term pregnancy has a positive influence, but only in nulliparous women, by lowering the risk of emergency caesarean section evidently without increasing the risk on adverse outcome in newborns.

Abstract
Labor induction and cervical ripening are widely utilized and new methods are constantly being investigated. Prostaglandins have been shown to be effective labor induction agents and, in particular, were compared with other prostaglandin preparations; vaginal misoprostol used off-label was associated with reduced failure to achieve vaginal delivery. The challenge is to provide this medication with the correct dosing for this indication and with the ability to discontinue the medication if needed, all while ensuring essential maternal and neonatal safety. The misoprostol vaginal insert initiates cervical ripening using a delivery system that controls misoprostol release and can be rapidly removed. This article reviews the development, safety and efficacy of the misoprostol vaginal insert for induction of labor and cervical ripening, and will focus on vaginally administered prostaglandins.

Abstract
BACKGROUND Induction of labour using pharmacological and mechanical methods can increase complications. Complementary and alternative medicine methods including hypnosis may have the potential to provide a safe alternative option for the induction of labour. However, the effectiveness of hypnosis for inducing labour has not yet been fully evaluated. OBJECTIVES To assess the effect of hypnosis for induction of labour compared with no intervention or any other interventions. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2014), handsearched relevant conference proceedings, contacted key personnel and organisations in the field for published and unpublished references. SELECTION CRITERIA All published and unpublished randomised controlled trials (RCTs) and cluster-RCTs of acceptable quality comparing hypnosis with no intervention or any other interventions, in which the primary outcome is to assess whether labour was induced. DATA COLLECTION AND ANALYSIS Two review authors assessed the one trial report that was identified (but was subsequently excluded). MAIN RESULTS No RCTs or cluster-RCTs were identified from the search strategy. AUTHORS' CONCLUSIONS There was no evidence available from RCTs to assess the effect of hypnosis for induction of labour. Evidence from RCTs is required to evaluate the effectiveness and safety of this intervention for labour induction. As hypnosis may delay standard care (in case standard care is withheld during hypnosis), its use in induction of labour should be considered on a case-by-case basis.Future RCTs are required to examine the effectiveness and safety of hypnotic relaxation for induction of labour among pregnant women who have anxiety above a certain level. The length and timing of the intervention, as well as the staff training required, should be taken into consideration. Moreover, the views and experiences of women and staff should also be included in future RCTs.

Abstract
PURPOSE To assess the main neonatal morbidity results in relation to induced labour indications. METHODS Historical groups from a total of 3,817 deliveries over a three year period (2009, 2010 and 2011) in "Mancha-Centro" Hospital (Alcázar de San Juan) formed the study group. All programmed and non-avoidable caesarean sections and pregnancies under 35 weeks were excluded. The main variable result was a neonatal morbidity variable made up of the Apgar score after 5 min, pH of umbilical artery <7.10 and the neonatal need for resuscitation type III-V. Multivariate analysis was used to control confounding variables. RESULTS The incidence of induced labour was 22.6 % (862). The highest indication was premature rupture of membranes for more than 12 h 22.8 % (190), poorly controlled diabetes 22.6 % (189) and oligoamnios 16.2 % (135). The rate of pH lower than 7.10 was 2.8 % (22), the rate of the Apgar score lower than 7 after 5 min was 0.2 % (2) and the neonatal need for resuscitation type III-IV was 5.7 % (48) for induced labour. The relation between induced labour and neonatal morbidity indicators were not statistically significant. 10.1 % (4) of induced labour for suspected intrauterine growth restriction and 8.6 % (10) of postterm pregnancies required neonatal resuscitation type III-IV. DISCUSSION No relation was found between induced labour and the neonatal morbidity indicators. The highest neonatal risk indicator is when a intrauterine growth restriction, hypertensión/preeclampsia or a postterm pregnancy is suspected.

Abstract
OBJECTIVES To determine the incidence of uterine tachysystole (UT) and its association with neonatal depression or metabolic acidemia (DEP). METHODS This retrospective study comprised all 6234 women at ≥ 37 weeks' gestation who were monitored during the last 4 hours of tracings before birth in an academic community hospital. DEP was defined by an umbilical artery base deficit value ≥ 10 mmol/L or a 5-minute Apgar ≤ 6 and included 77 births. UT was defined by >15 contractions in 30 minutes. RESULTS The overall incidence of UT was 18.3% (1139/6234). In 4.2% (260/6234) UT persisted for >60 min. The rate of UT was similar in births with DEP (14.3%, 11/77) compared to those without DEP (18.3%, 1128/6157; p=0.45). In births with UT, only 1.0% (11/1139) developed DEP. The DEP group had more decelerations at almost every level of contractions and a higher cesarean rate of 49.4% (38/77) compared to 24.0% (1468/6124); p=<0.001 in the group without DEP. CONCLUSIONS UT was common, occasionally prolonged and almost always benign. Fetuses with DEP had no more UT than those without DEP. Many babies with DEP declared their vulnerability with decelerations at contraction rates below UT levels and the great majority of them never experienced UT.

Abstract
Objective. To determine the risks of induced term delivery to the mother and neonate at different gestational ages in the absence of obstetric indications. Study Design. All deliveries in New South Wales (NSW) between 1998 and 2008 were reviewed from the MDC. Uncomplicated pregnancies which were induced for non-obstetric reasons after 37 completed weeks were reviewed. This was a retrospective, historical cohort study, and both maternal and neonatal outcomes were analysed and compared between different gestational age groups. Results. An analysis of the data shows that induction of labour after 37 completed weeks exposes the fetus and mother to different levels of risk at different gestations. Conclusion. In an uncomplicated pregnancy, induction of labour is associated with the highest rate of neonatal complication at 37 weeks as compared with rates at later gestations. With each ensuing week, the neonatal outcome improves. At 40 weeks the likelihood of neonatal intensive care admission, low Apgar scores, and perinatal death rate is at its lowest, and then there is a slight but not significant rise after 41 weeks. The likelihood of caesarean section is the lowest when inductions are carried out at 39 weeks and is the highest at 41 weeks and over.

Abstract
OBJECTIVE childbearing women and their midwives differ in their diagnoses of the onset of labour. The symptoms women use to describe the onset of labour are associated with the process of labour. Perinatal factors and women's attitudes may be associated with the administration of epidural analgesia. Our study aimed to assess the correlation between women's perception of the onset of labour and the frequency and timing of epidural analgesia during labour. DESIGN prospective cohort study. SETTING 41 maternity units in Lower Saxony, Germany. PARTICIPANTS 549 nulliparae (as defined in the "Methods" section) and 490 multiparae giving birth between April and October 2005. Women were included after 34 completed weeks of gestation with a singleton in vertex presentation and planned vaginal birth. MEASUREMENTS the association between women's symptoms at the onset of labour and the administration of epidural analgesia - frequency, timing in relation to onset of labour and cervical dilatation - was assessed. The analysis was performed by Kaplan-Meiers estimation, logistic regression and Cox regression. FINDINGS a total of 174 nulliparae and 49 multiparae received epidural analgesia during labour. Nulliparae received it at a median time of 5.47hrs (range: 0.25-51.17hrs) after onset of labour, at a median cervical dilatation of 3.3cm (range: 1.0-10.0cm). In multiparae, epidural analgesia was applied at a median time of 3.79hrs (range: 0.42-28.55hrs) after onset of labour; the median cervical dilatation was 3.0cm (range: 1.0-8.0cm). Women who were admitted with advanced cervical dilatation received epidural analgesia less often. Women who defined their onset of labour earlier than it was diagnosed by their midwives received epidural analgesia earlier. Gastrointestinal symptoms and irregular pain at the onset of labour were associated with later administration of epidural analgesia. Induction of labour was associated with a reduced interval from the onset of labour to epidural analgesia. KEY CONCLUSIONS women's self-diagnosis of the onset of labour and their perception of their labour duration when meeting their midwives has some impact on their admission to the labour ward and the timing of epidural analgesia. IMPLICATIONS FOR PRACTICE consideration of women's own perceptions and expectations regarding the onset and process of labour is necessary for individual care during labour.

Abstract
OBJECTIVE To characterize the response to labor induction with prostaglandin E2 (PGE2) and to identify risk factors for induction failure. METHODS A prospective controlled study of women admitted for labor induction with PGE2. Maternal characteristics, Bishop score and sonographic cervical length were documented at admission. The change in cervical characteristics and the emergence of uterine contractions following each application of PGE2 were analyzed. RESULTS Of the 88 women who were included in the study, 19 (21.6%) failed to response to PGE2. The following factors were independently associated with induction failure: nulliparity (odds ratio [OR] = 5.9, 95% confidence interval (CI): 1.2-30.2), pre-pregnancy body mass index >25 kg/m2 (OR = 5.4, 95% CI: 1.1-26.5), Bishop score <4 (OR = 2.3, 95% CI: 1.05-14.4), cervical length <25 mm (OR = 0.2, 95% CI: 0.1-0.8) and the development of uterine contractions in response to the first application of PGE2 (OR = 0.4, 95% CI: 0.1-0.93). Overall, most women required only one (60.9%) or two (85.5%) applications of PGE2 to achieve successful induction. The number of applications of PGE2 required to achieve successful induction was related to parity and cervical status at presentation. CONCLUSIONS Overall, most women who eventually respond to PGE2 do so following the first two applications of PGE2, and the contribution of subsequent applications is relatively small and related to cervical status at admission.

Abstract
OBJECTIVE To describe the risk of maternal sepsis associated with obesity and other understudied risk factors such as operative vaginal delivery. DESIGN Population-based, case-control study. SETTING North NHS region of Scotland. POPULATION All cases of pregnant, intrapartum and postpartum women with International Classification of Disease-9 codes for sepsis or severe sepsis recorded in the Aberdeen Maternal and Neonatal Databank (AMND) from 1986 to 2009. Four controls per case selected from the AMND were frequency matched on year-of-delivery. METHODS Cases and controls were compared; significant variables from univariable regression were adjusted in a multivariable logistic regression model. MAIN OUTCOME MEASURES Dependent variables were uncomplicated sepsis or severe ('near-miss') sepsis. Independent variables were demographic, medical and clinical delivery characteristics. Unadjusted and adjusted odds ratios (OR) with 95% confidence intervals (95% CI) are reported. RESULTS Controlling for mode of delivery and demographic and clinical factors, obese women had twice the odds of uncomplicated sepsis (OR 2.12; 95% CI 1.14-3.89) compared with women of normal weight. Age <25 years (OR 5.15; 95% CI 2.43-10.90) and operative vaginal delivery (OR 2.20; 95% CI 1.02-4.87) were also significant predictors of sepsis. Known risk factors for maternal sepsis were also significant in this study (OR for uncomplicated and severe sepsis respectively): multiparity (OR 6.29, 12.04), anaemia (OR 3.43, 18.49), labour induction (OR 3.92 severe only), caesarean section (OR 3.23, 13.35), and preterm birth (OR 2.46 uncomplicated only). CONCLUSIONS Obesity, operative vaginal delivery and age <25 years are significant risk factors for sepsis and should be considered in clinical obstetric care.

Abstract
AIM To determine induction trends and delivery, maternal and neonatal health outcomes by gestational age following induction at term for women having a first baby. METHODS Linked birth and hospital data were used to examine the rates of adverse maternal and neonatal health outcomes for the period 2001-2007, among the 212,389 nullipara with singleton cephalic-presenting fetuses delivering between 37(0) and 41(6) weeks of gestation. Rates of caesarean delivery, neonatal transfers and overall severe neonatal and maternal adverse outcomes were determined by gestational age. RESULTS Between 1990 and 2008, nulliparous term inductions as a proportion of all births increased from 5518 (6.8%) to 11,166 (12.5%). More than 60% of these inductions are performed before 41 weeks. Among induced nullipara, 30.4% delivered by caesarean section. Adverse neonatal outcomes and transfer rates were lowest at 39-40 weeks (overall 2.1 and 0.5%, respectively), regardless of labour onset. Maternal morbidity increased at 40 weeks (from 1.1 to 1.3%) for women in spontaneous labour, was relatively stable in those undergoing induction of labour between 37 and 40 weeks (1.8%) and decreased with gestational age until 40 weeks in those undergoing a prelabour caesarean delivery (from 3.1 to 0.8%). CONCLUSION NSW has high rates of both induction and caesarean section following induction. This study highlights the changes to clinical practice that may help reduce the rate of caesarean births in nullipara.

Abstract
OBJECTIVE Multiple observational studies have emphasized the increased risk of elective induction versus spontaneous labor. We estimated the risks of elective induction before 39 weeks compared to expectant management. METHODS Using a single institution's delivery data (1996-2004), we identified women with uncomplicated term gestations who underwent elective induction before 39 weeks (Early Induction Group). A comparison group of women eligible for elective induction before 39 weeks but who were managed expectantly was created by identifying the remaining deliveries ≥ 39 weeks and excluding women with "established" pregnancy complications such as diabetes or heart disease (Expectant Management Group), but retaining women with complications that may have developed while waiting, e.g. gestational hypertension or abruption. RESULTS Pregnancies in the Early Induction Group were generally not at increased risk for morbidity when compared to the entire Expectant Management Group, in whom 49% developed pregnancy complications or went postdates. These pregnancies had poorer maternal and neonatal outcomes when compared to patients who remained uncomplicated with spontaneous labor onset, thus reducing the overall benefit of expectant management. CONCLUSIONS Failure to account for the large proportion of women who develop late pregnancy complications can falsely elevate the estimated risk of elective induction prior to 39 weeks.

Abstract
A recent systematic review found no "good quality evidence" that elective induction of labor confers substantial benefits to either mothers or babies, but concluded that elective induction is associated with a decreased risk of "cesarean delivery." Admittedly, elective induction was qualified as "at 41 weeks of gestation and beyond" with 42 weeks being proclaimed as the cutoff point between "elective" and "medically indicated." Major predictors of the success of any induction and the subsequent mode of delivery, such as parity and cervical status, were not taken into account. Crucial boundaries between what is elective and what is selective, what is medically indicated and what is not, and what is maternal request or persuasive coercion, remain as vague as ever.
