Factors that influence the choice for neonatal resuscitation in periviable deliveries

Background Periviable preterm birth, defined as delivery between 20+0/7 to 25+6/7 weeks, represents less than 1% of all births but contributes to up to 40% of all infant deaths. Scenarios with high risks of morbidity and mortality to the maternal-neonatal dyad may result in periviable preterm delivery. These situations require shared decision making between healthcare teams and families to decide whether maternal and neonatal patients are candidates for obstetric interventions and neonatal resuscitation at delivery, respectively, and to determine the optimal mode of delivery at the cusp of fetal viability. Objective The primary objective is to describe the influence of patient demographics (i.e. maternal race) and societal factors (i.e. maternal religion) on the decision between neonatal resuscitation and comfort care in periviable deliveries. Our secondary goals are: 1. to quantify the use of obstetric interventions (antenatal steroids for fetal lung maturity, magnesium sulfate for fetal neuroprotection, tocolytics and GBS prophylaxis) at the threshold of viability and 2. to establish whether planned neonatal resuscitation versus comfort care influenced the choice of cesarean versus vaginal delivery. Methods This project is a retrospective cohort study; electronic medical records were queried for data at Ascension St. Vincent Women's Hospital of mothers and neonates delivered at 22 0/7 to 24 6/7 from January 1, 2016 to July 31, 2020. Study patients were separated to compare outcomes between those that received neonatal resuscitation and those for whom comfort care was provided at 22, 23, and 24 weeks gestational age. Results were further stratified by obstetric interventions, mode of delivery, and maternal race and maternal religion with statistical analysis utilizing Fisher's Exact Test. Results Of the 111 patient charts originally identified, 73 patients met inclusion criteria. For those patients that opted for obstetric interventions, the most likely intervention was antenatal steroids (86%), followed by magnesium for fetal neuroprotection (63%) and tocolytics (63%), with the least likely intervention being Group Beta Streptococcus antibiotic prophylaxis (43%). The overall cesarean delivery rate was 53%. Cesarean delivery was selected with increasing gestational age: 9.1%, 52%, and 67% at 22, 23, and 24 weeks respectively. While there was no significant difference in those that opted for comfort care versus neonatal resuscitation at 22 weeks, the majority of patients at 23 and 24 weeks overwhelmingly opted for resuscitation; 5 infants (45%) were resuscitated at 22 weeks, 24 infants (96%) at 23 weeks, and 36 infants (97%) at 24 weeks. Planned neonatal resuscitation increased by gestational age. Patients opting for comfort care were more likely to deliver vaginally (87%) versus those that opted for resuscitation (41%), (Fisher's Exact Test, p=0.02), with the most common diagnoses documented for cesarean delivery being malpresentation followed by fetal distress. As for the influence of maternal race, African American patients opted for resuscitation 100% of the time, regardless of gestational age, in comparison to Caucasian (87%) and "other" (62%) counterparts. As for maternal religion, there was no significant difference between patients that self-identified as Christian, Roman Catholic, Unaffiliated or Other and their decision for neonatal resuscitation at 22 weeks. However, at 23 and 24 weeks, the only patients to opt in favor of comfort care were patients that were Unaffiliated with an organized religion. Overall, our infant survival rates were 7.6%, 44%, 63%, at 22, 23, and 24 weeks respectively, with an overall survival rate of 41%. Conclusion While the decision to resuscitate periviable preterm infants is multifactorial, demographic and societal factors influence the decision for planned resuscitation for this vulnerable patient population. Planned neonatal resuscitation rates were higher among patients identified as African American than other demographics included in this study. Patients not affiliated with an organized religion are less likely to opt for resuscitation at later gestational ages. Regardless ofplans for resuscitation, the majority of patients received obstetric interventions including antenatal steroids and cesarean delivery. These findings may be used by clinicians for shared decision making during future antenatal counseling sessions.

Continuous care during labor by maternity care assistants in the Netherlands vs care-as-usual: a randomized controlled trial

Continuous support during labor has many benefits, including lower use of obstetrical interventions. However, implementation remains limited. Insights into birth outcomes as well as peripartum costs are essential to assess whether continuous care by a maternity care assistant is a potentially (cost) effective program to provide for all women. Continuous care during labor, provided by maternity care assistants, will reduce the use of epidural analgesia and peripartum costs due to a reduction in interventions. A randomized controlled trial, comparing continuous support during labor (intervention group) to care-as-usual (control group) with pre-specified intention-to-treat and per-protocol analyses. The primary outcome was epidural analgesia use. Secondary outcomes were use of other analgesia, referrals from midwife- to obstetrician-led care, modes of birth, hospital stay, sense of control (evaluated with the Labor Agentry Scale), maternal and neonatal adverse outcomes and peripartum costs. Data were collected using questionnaires. Anticipating incomplete adherence to providing continuous care, both intention-to-treat and per-protocol analyses were planned. Peripartum costs were estimated using a healthcare perspective. Mean costs per woman and cost differences between the intervention and control group were calculated. The population consisted of 1076 women with 54 exclusions and 30 discontinuations, leaving 992 women to be analyzed (515 continuous care and 477 care-as-usual). Intention-to-treat analyses showed statistically non-significant differences between the intervention and control group for epidural use (RR 0.88, 95%-CI 0.74 to 1.04, p=0.14) and peripartum costs (mean difference € 185.83, 95%-CI -€ 204.22 to € 624.54). Per-protocol analyses showed statistically significant decreases in epidural analgesia (RR 0.64, 95%-CI 0.48 to 0.84, p=0.001), other analgesia (RR 0.59, 95%-CI 0.37 to 0.94, p=0.02), cesarean sections (RR 0.53, 95%-CI 0.29 to 0.95, p=0.03) and increase in spontaneous vaginal births (RR 1.09, 95%-CI 1.01 to 1.18, p=0.001) in the intervention group, but difference in total peripartum costs remained statistically non-significant (mean difference € 246.55, 95%-CI -€ 539.14 to € 13.50). If the provision of continuous care given by maternity care assistants during labor can be secured, continuous care leads to more vaginal births and less epidural use, pain medication and cesarean sections, while not leading to a difference in peripartum costs compared to care-as-usual.

Busy day effect on the use of obstetrical interventions and epidural analgesia during labour: a cross-sectional register study of 601 247 deliveries

BackgroundDaily delivery volume might affect the quality of obstetric care. We explored the busy day effect on selected obstetrical interventions and epidural analgesia performed during labour in different sized delivery hospitals and on the Finnish obstetric ecosystem.MethodsWe conducted a cross-sectional study on Finnish Medical Birth Register data of singleton pregnancies (N = 601,247) from 26 delivery hospitals from 2006 to 2016. Delivery hospitals were stratified by annual delivery volume: C (category) 1: < 1000, C2: 1000–1999, C3: 2000–2999, C4: ≥3000, and C5: university hospitals. The exposure variables were defined as quiet, optimal, and busy days determined based on daily delivery volume distribution in each hospital category. Quiet and busy days included approximately 10% of the lowest and highest delivery volume days, while the rest were defined as optimal. Outcome measures were unplanned caesarean section (CS), instrumental delivery, induction of labour, and epidural analgesia. We compared the incidence of outcomes in quiet vs. optimal, busy vs. optimal, and busy vs. quiet days using logistic regression. The statistical significance level was set at 99% to reduce the likelihood of significant spurious findings.ResultsIn the total population, the incidence of instrumental delivery was 8% (99% CI 2–15%) lower on quiet than on optimal days. In smaller hospitals (C1 and C2), unplanned caesarean sections were performed up to one-third less frequently on busy than optimal and quiet days. More (27%, 99% CI 12–44%) instrumental deliveries were performed in higher delivery volume hospitals (C4) on busy than quiet days. In C1-C3, deliveries were induced (12–35%) less often and in C5 (37%, 99% CI 28–45%) more often on busy than optimal delivery days. More (59–61%) epidural analgesia was performed on busy than optimal and quiet days in C4 and 8% less in C2 hospitals.ConclusionsPooled analysis showed that busyness had no effect on outcomes at the obstetric ecosystem level, but 10% fewer instrumental deliveries were performed in quiet than on busy days overall. Furthermore, dissecting the data shows that small hospitals perform less, and large non-tertiary hospitals perform more interventions during busy days.

Mindful awareness as a mechanism of change for natural childbirth in pregnant women with high fear of childbirth: a randomised controlled trial

BackgroundMindfulness-Based Childbirth and Parenting (MBCP) is effective in increasing natural childbirth in pregnant women with high fear of childbirth (FOC) as compared to enhanced care as usual (ECAU). We aimed to examine through which pathway of action MBCP reaches this effect, based on a model of approaching or avoiding the challenges related to childbirth.MethodsOne hundred eleven pregnant women with high FOC were measured pre- and post-intervention on FOC (emotion pathway), catastrophic beliefs about labour pain (cognition pathway) and mindful awareness (attention pathway). A multiple mediation model was used to examine through which pathway the mechanism of change operated in relation to approach (i.e., natural childbirth) versus avoidance (i.e., self-requested caesarean section).ResultsIt was found that greater mindful awareness (18% R2 = 0.18, F[1107] = 22.77, p < 0.0001) was the only significant mechanism of change operating through the attentional pathway leading to natural childbirth. More specifically, nonreactivity to inner experience (a facet of mindful awareness) showed to be the strongest mechanism of change. More extensive meditation practice was positively associated with natural childbirth; however, the number of completed MBCP sessions was not associated with the outcome.ConclusionsAn increase in mindful awareness was the strongest mechanism of change for better adaptation to the challenges of childbirth. Decreases in neither FOC nor catastrophic beliefs about labour pain were identified as mechanisms of change. Additionally, the more one meditated, the more one was inclined towards a natural childbirth. MBCP enhances adaptation to the challenges of childbirth and less use of obstetric interventions in the presence of high FOC.Trial registrationThe Netherlands Trial Register (NTR; 4302).

Neonatal outcomes associated with obstetric interventions performed during labor in nulliparous women

Objective: to analyze neonatal outcomes associated with obstetric interventions performed during labor in low-risk nulliparous women. Methods: a cross-sectional observational study of 534 low-risk nulliparous women. Results: interruption of skin-to-skin contact after delivery was shown to be associated with obstetric interventions such as cardiotocography at admission, oxytocin in labor, amniotomy, and episiotomy. The need for positive pressure ventilation and oxygen therapy was associated with the encouragement of the Valsalva maneuver; the performance of this maneuver was also associated with interventions such as amniotomy, episiotomy and directed pulling. Conclusion: the study showed that the use of obstetric interventions during labor in low-risk women is associated with unfavorable neonatal outcomes that lead to the need for further interventions after delivery.

Intention to treat: obstetrical management at the threshold of viability

Despite medical advances in the care of extremely preterm neonates and growing acceptance of resuscitation at 23 and even 22 weeks gestation, controversy remains concerning the use of antepartum obstetric intervention s that are intended to improve outcomes in the setting of anticipated extremely preterm birth. In the absence of demonstrated benefit at <23 weeks gestation and with uncertain benefit at 23 weeks gestation, previous obstetric committee opinions have advised against their use at these gestational ages. The purpose of this study was to review the use of obstetric intervention s at the threshold of viability based on neonatal resuscitation plan and to review the odds of survival to neonatal intensive care unit discharge based on use of obstetric intervention s with adjustment for neonatal factors. This retrospective study of 6 study centers reviewed pregnant patients who were admitted between 22+0/7 and 24+6/7 weeks gestation facing delivery from 2011-2015. Patients with known anomalies or missing data were excluded. Records were reviewed for demographics, resuscitation plan, and obstetric intervention s. Mode of delivery, delivery room care, and final infant dispositions were recorded. Multiple gestations were included as 1 pregnancy in regard to the use of obstetric intervention s and were excluded from survival analysis. Four hundred seventy-eight mothers met the inclusion criteria. When resuscitation was planned, mothers were more likely to receive all conventional obstetric intervention s (antenatal steroids, magnesium sulfate for neuroprotection, tocolytics, and Group Beta Streptococcus prophylaxis), regardless of gestational age at admission, and were more likely to be delivered by cesarean section (P<.05). Analyzed as a group, when antenatal steroids, magnesium sulfate, tocolytics and Group Beta Streptococcus prophylaxis were administered, the odds of survival to neonatal intensive care unit discharge increased for newborn infants who were born at 22 (odds ratio, 11.33; 95% confidence interval, 1.405-91.4) and 23 weeks gestation (odds ratio, 15.5; 95% confidence interval, 3.747-64.11; P<.05). In singletons, the odds of survival to neonatal intensive care unit discharge was not improved by cesarean delivery vs vaginal delivery, even after adjustment for the use of additional interventions, weight, gender, and gestational age (odds ratio, 1.0; 95% confidence interval, 0.59-1.8; P=.912). In this study, when postnatal resuscitation was planned at 22 and 23 weeks gestation, women were more likely to receive antenatal steroids, magnesium sulfate, and antibiotics; provision of this bundle imparted survival benefit at 23 weeks gestation but could not be demonstrated at 22 weeks gestation because of the small sample size. These findings support of neonate-oriented obstetric interventions in the setting of delivery at 23 weeks gestation when resuscitation is planned and further exploration of optimal obstetric care when resuscitation of infants who were born at 22 weeks gestation is anticipated.

Impact of Provider Payment Structure on Obstetric Interventions and Outcomes: A Difference-in-Differences Analysis.

Traditionally, Canadian physicians provide care on a fee-for-service (FFS) basis; however, this model has been criticized as it incentivizes quantity of care over quality of care. Consequently, all Canadian provinces and territories have implemented some form of alternative payment plan. Evaluation of the impact of these policy changes, however, has typically focused on family physicians as opposed to specialists. On January 1, 2004, obstetricians at the Medicine Hat Regional Hospital (MHRH) transitioned from FFS to salary. A difference-in-differences analysis was used to examine the impact of changes in obstetrician payment structure on the use of obstetric interventions and neonatal outcomes controlling for temporal trends at MHRH (intervention group) and the Chinook Regional Hospital (CRH; comparison group) from 2002 to 2005. Between the pre-intervention period (2002-2003) and the post-intervention period (2004-2005), the rate of cesarean delivery increased significantly at both sites. Following adjustment for time of day, day of week, and antepartum risk score, the difference-in-difference estimator demonstrated a 5.8% (95% CI 1.5-10.0) increase in cesarean deliveries performed by obstetricians at MHRH compared with cesarean deliveries done at CRH after accounting for baseline differences and temporal trends. No significant differences were observed for family physicians. No significant differences were observed for other obstetric interventions or neonatal outcomes. Under an FFS model, obstetricians are incentivized to cesarean delivery due to the increased reimbursement rate; however, the increase in cesarean deliveries at MHRH following the transition to a salary model was unexpected. This finding suggests that, in Canada, financial incentives are not a factor that explains the increasing rate of cesarean delivery.

Evidence of Overuse? Patterns of obstetric interventions during labour and birth among Australian mothers

There is global concern for the overuse of obstetric interventions during labour and birth among some population groups. Concern is due to increasing rates of morbidity and mortality associated with caesarean section. The aim of this study is to characterise the use of obstetric intervention among Australian mothers. The association between socio-demographic characteristics and birth type were compared, and logistic regression was undertaken to assess the likelihood of receiving obstetric intervention. Non-indigenous, urban and wealthier mothers had higher rates of all obstetric interventions, not attributable to medical or lifestyle risk factors.

Evidence of overuse? Patterns of obstetric interventions during labour and birth among Australian mothers

BackgroundThere is global concern for the overuse of obstetric interventions during labour and birth. Of particular concern is the increasing amount of mothers and babies experiencing morbidity and mortality associated with caesarean section compared to vaginal birth. In high-income settings, emerging evidence suggests that overuse of obstetric intervention is more prevalent among wealthier mothers with no medical need of it. In Australia, the rates of caesarean section and other obstetric interventions are rising. These rising rates of intervention have been mirrored by a decreasing rate of unassisted non-instrumental vaginal deliveries. In the context of rising global concern about rising caesarean section rates and the known health effects of caesarean section on mothers and children, we aim to better characterise the use of obstetric intervention in the state of Queensland, Australia by examining the characteristics of mothers receiving obstetric intervention. Identifying whether there is overuse of obstetric interventions within a population is critical to improving the quality, value and appropriateness of maternity care.MethodsThe association between demographic characteristics (at birth) and birth delivery type were compared with chi-square. The percentage of mothers based on their socioeconomic characteristics were reported and differences in percentages of obstetric interventions were compared. Multivariate analysis was undertaken using multiple logistic regression to assess the likelihood of receiving obstetric intervention and having a vaginal (non-instrumental) delivery after accounting for key clinical characteristics.ResultsIndigenous mothers, mothers in major cities and mothers in the wealthiest quintile all had higher percentages of all obstetric interventions and had the lowest percentages of unassisted (non-instrumental) vaginal births. These differences remained even after adjusting for other key sociodemographic and clinical characteristics.ConclusionsDifferences in obstetric practice exist between economic, ethnic and geographical groups of mothers that are not attributable to medical or lifestyle risk factors. These differences may reflect health system, organisational and structural conditions and therefore, a better understanding of the non-clinical factors that influence the supply and demand of obstetric interventions is required.

Creating Guardians of Physiologic Birth: The Development of an Educational Initiative for Student Midwives in the Netherlands.

Women want positive birth experiences with high quality maternity care that is neither too much, too soon, nor too little, too late. Research confirms the effectiveness of midwifery care, and the midwifery approach to birth as physiologic may counter the upward trend of the unnecessary medicalization of birth. The role of guardian of physiologic birth is seen as central to midwifery practice; however, medical hegemony has led to the subordination of midwives, which inhibits them in fulfilling the role as guardian of physiologic birth. Learning to become powerful advocates of physiologic birth creates midwives able to speak up for effective, evidence-based maternity care and challenge the unnecessary use of obstetric intervention. Midwifery education has a role to fulfil in molding midwives who are able to assume this role. This brief report describes the development of an educational prototype aimed at increasing student midwife agency as an advocate of physiologic birth. This was done using rapid prototyping (RP) methodology, in which important stakeholders gave input and feedback during the educational design and development process. Input from stakeholders led to the inclusion of persuasive communication strategies and discussion and debate as teaching methodologies in order to increase student midwife agency to argue for physiologic birth. Reflective evidence-based practice, using the Optimality Index-Netherlands, allowed students to reflect on their practice while providing a framework for discussion. Working with the RP methodology allowed for the development of a prototype that reflected the needs of midwifery stakeholders and was mindful of material and human resources.

Barriers and enablers in the implementation of a program to reduce cesarean deliveries

Conducting audits, implementing best practices and giving feedback to the professionals have shown considerable promise in reducing rates of cesarean delivery and mother-child morbidity. The purpose of the study is two-fold: a) to identify the factors that facilitate change in current practices and thus reduce the use of obstetric interventions, and b) to better understand the barriers to such changes. To reach these objectives, the study analyzed the experiences of professionals participating in a program to reduce cesarean rates in 20 hospitals in Andalusia (Spain). A qualitative exploratory study was conducted. Participants were 14 ob-gyns and 14 nurse-midwives who work for Spain’s National Healthcare System and have been involved in the program. To gather information, in-depth individual interviews were used. The interview was designed to examine factors affecting the quality of care, such as issues related to policy/management, hospitals, practitioners and patients. The barriers identified include: 1) At the policy/management level: limited influence of institutional policy and the scant political commitment perceived. 2) At the organizational level: separation of the hierarchical structure of doctors from that of nurse-midwives, few positive incentives and the strong threat of sanctions for malpractice, inappropriate reorganization of midwife/obgyns competences. 3) At the healthcare staff and facility level: reluctance to change accentuated by years of professional practice. 4) Physical resources: obsolete delivery rooms with a medical look. 5) At the professional level: medical and legal pressure, cesarean delivery considered safe in the event of a legal claim, low motivation due to decline in working conditions, convenience-based practices. 6) Woman giving birth and her family: fear of pain, impatience while waiting for process to occur, misinformation. The enablers include: 1) At the organizational level: good coordination with pediatrics and emergency departments, 2) Training: skills updates for a less-interventionist approach, increased awareness, 3) Health professionals: satisfaction for a job well done, recognition by patients. 4) Woman giving birth: information circuits for patients and their families, trust in health professionals. The results can contribute to the design of more effective knowledge translation interventions to reduce cesarean sections, based on overcoming obstacles, reinforcing enabling factors and attempting to (re)define the boundaries between research and practice.

Are freestanding midwifery units a safe alternative to obstetric units for low-risk, primiparous childbirth? An analysis of effect differences by parity in a matched cohort study

BackgroundIntrapartum complications and the use of obstetric interventions are more common in primiparous childbirth than in multiparous childbirth, leading to concern about out of hospital birth for primiparous women. The purpose of this study was to determine whether the effect of birthplace on perinatal and maternal morbidity and the use of obstetric interventions differed by parity among low-risk women intending to give birth in a freestanding midwifery unit or in an obstetric unit in the North Denmark Region.MethodsThe study is a secondary analysis of data from a matched cohort study including 839 low-risk women intending birth in a freestanding midwifery unit (primary participants) and 839 low-risk women intending birth in an obstetric unit (individually matched control group). Analysis was by intention-to-treat. Conditional logistic regression analysis was applied to compute odds ratios and effect ratios with 95% confidence intervals for matched pairs stratified by parity.ResultsOn no outcome did the effect of birthplace differ significantly between primiparous and multiparous women. Compared with their counterparts intending birth in an obstetric unit, both primiparous and multiparous women intending birth in a freestanding midwifery unit were significantly more likely to have an uncomplicated, spontaneous birth with good outcomes for mother and infant and less likely to require caesarean section, instrumental delivery, augmented labour or epidural analgesia (although for caesarean section this trend did not attain statistical significance for multiparous women). Perinatal outcomes were comparable between the two birth settings irrespective of parity. Compared to multiparas, transfer rates were substantially higher for primiparas, but fell over time while rates for multiparas remained stable.ConclusionsFreestanding midwifery units appear to confer significant advantages over obstetric units to both primiparous and multiparous mothers, while their infants are equally safe in both settings. Our findings thus support the provision of care in freestanding midwifery units as an alternative to care in obstetric units for all low-risk women regardless of parity. In view of the global rise in caesarean section rates, we consider it an important finding that freestanding midwifery units show potential for reducing first-birth caesarean.

Impact of obstetric interventions on condition at birth in extremely preterm babies: evidence from a national cohort study.

BackgroundTo investigate perinatal decision-making and the use of obstetric interventions, we examined the effects of antenatal steroids, tocolysis, and delivery mode on birth in a good condition (defined as presence of an infant heart rate >100 at five minutes of age) and delivery-room (DR) death in extremely preterm deliveries.MethodsProspective cohort of all singleton births in England in 2006 at 22–26 weeks of gestation where the fetus was alive at the start of labour monitoring or decision to perform caesarean section. Odds ratios adjusted for potential confounders (aOR) were calculated using logistic regression.ResultsOne thousand seven hundred twenty two singleton pregnancies were included. 1231 women received antenatal steroids, 437 tocolysis and 356 delivered by Caesarean section. In babies born vaginally, aOR between a partial course of steroids and improved condition at birth was 1.84, 95% CI: 1.20 to 2.82 and, for a complete course, 1.63, 95% CI: 1.08 to 2.47; for DR death, aORs were 0.34 (0.21 to 0.55) and 0.41 (0.26 to 0.64) for partial and complete courses of steroids. No association was seen for steroid use in babies delivered by Caesarean section. Tocolysis was associated with improved condition at birth (aOR 1.45, 95% CI: 1.05 to 2.0) and lower odds of death (aOR 0.48, 95% CI: 0.32 to 0.73). In women without spontaneous labour, Caesarean delivery at ≤24 and 25 weeks was associated with improved condition at birth ((aORs 12.67 (2.79 to 57.60) and 4.94 (1.44 to 16.90), respectively) and lower odds of DR death (aORs 0.03 (0.01 to 0.21) and 0.13 (0.03 to 0.55)). There were no differences at 26 weeks gestation or in women with spontaneous labour.ConclusionsAntenatal steroids are strongly associated with improved outcomes in babies born vaginally. Tocolysis was associated with improvements in all analyses. Effects persisted after adjustment for perinatal decision-making. However, associations between delivery mode and birth outcomes may be attributable to case selection.Electronic supplementary materialThe online version of this article (doi:10.1186/s12884-016-1154-y) contains supplementary material, which is available to authorized users.

Safety of labour and delivery following closures of obstetric services in small community hospitals.

In recent decades, many smaller hospitals in British Columbia, Canada, have stopped providing planned obstetric services. We examined the effect of these service closures on the labour and delivery outcomes of pregnant women living in affected communities. We used maternal postal codes to identify delivery records (1998-2014) of women residing in a community affected by service closure. The records were obtained from the British Columbia Perinatal Data Registry. We examined the effect of the closures using a within-communities fixed-effects framework and included similar-sized communities without service closures to control for underlying time trends. The primary outcome was a previously published composite measure of labour and delivery safety, the Adverse Outcome Index, which includes adverse events such as birth injury and unanticipated operative procedures, and includes weights for severity of adverse events. Secondary outcomes included maternal or newborn transfer, and use of obstetric interventions. We found little evidence that closure of planned obstetric services affected the risk of composite adverse maternal-newborn outcome (-0.4 excess adverse events per 100 deliveries, 95% confidence interval [CI] -2.0 to 1.1), or most other secondary outcomes. The severity of composite outcome events decreased following the closures (rate ratio 0.58, 95% CI 0.36 to 0.89). Closures were associated with increases in use of epidural analgesia (3.4 excess events per 100 deliveries, 95% CI 0.4 to 6.3) and length of antepartum stay (0.6 h, 95% CI 0.1 to 1.0 h). Closure of planned obstetric services in low-volume hospitals was not associated with an increase or decrease in frequency of adverse events during labour and delivery.

Labor and birth care by nurse with midwifery skills in Brazil.

BackgroundThe participation of nurses and midwives in vaginal birth care is limited in Brazil, and there are no national data regarding their involvement. The goal was to describe the participation of nurses and nurse-midwives in childbirth care in Brazil in the years 2011 and 2012, and to analyze the association between hospitals with nurses and nurse-midwives in labor and birth care and the use of good practices, and their influence in the reduction of unnecessary interventions, including cesarean sections.MethodsBirth in Brazil is a national, population-based study consisting of 23,894 postpartum women, carried out in the period between February 2011 and October 2012, in 266 healthcare settings. The study included all vaginal births involving physicians or nurses/nurse-midwives. A logistic regression model was used to examine the association between the implementation of good practices and suitable interventions during labor and birth, and whether care was a physician or a nurse/nurse-midwife led care. We developed another model to assess the association between the use of obstetric interventions during labor and birth to the personnel responsible for the care of the patient, comparing hospitals with decisions revolving exclusively around a physician to those that also included nurses/nurse-midwives as responsible for vaginal births.Results16.2 % of vaginal births were assisted by a nurse/nurse-midwife. Good practices were significantly more frequent in those births assisted by nurses/nurse-midwives (ad lib. diet, mobility during labor, non-pharmacological means of pain relief, and use of a partograph), while some interventions were less frequently used (anesthesia, lithotomy position, uterine fundal pressure and episiotomy). In maternity wards that included a nurse/nurse-midwife in labour and birth care, the incidence of cesarean section was lower.ConclusionsThe results of this study illustrate the potential benefit of collaborative work between physicians and nurses/nurse-midwives in labor and birth care. The adoption of good practices in managing labor and birth could be the first step toward more effective obstetric and midwifery care in Brazil. It may be easier to introduce new approaches rather than to eliminate old ones, which may explain why the reduction of unnecessary interventions during labor and birth was less pronounced than the adoption of new practices.Electronic supplementary materialThe online version of this article (doi:10.1186/s12978-016-0236-7) contains supplementary material, which is available to authorized users.

Labor and Birth Care Satisfaction Associated With Medical Interventions and Accompaniment During Labor Among Chilean Women.

Satisfaction with care during labor and birth has been associated with various obstetric variables. The purpose of this study was to determine which labor and birth procedures are significant predictors of maternal patient satisfaction in a large cross-sectional sample. An observational, cross-sectional study of 1660 women giving birth in Chilean public hospital facilities was conducted from 2012 to 2013. Data were collected from 9 different hospitals in 8 regions of Chile using 2 instruments, including the American College of Nurse-Midwives Intrapartum Care Data Set and a locally validated measure of maternal well-being. Women were eligible if they arrived at the labor and delivery unit during early labor (2-3 centimeters dilated) and spent at least 4 hours in labor at the facility. In the current analysis, odds ratios were calculated using ordinal logistic regression for association with a less optimal well-being score (possible outcome values were optimal, adequate, and minimal). Odds ratios were adjusted for age, education, single status, and parity (nulliparous vs multiparous). Stepwise regression was used to identify the procedural factors that were significantly associated with labor and birth care satisfaction. Factors significantly associated with lower satisfaction were cesarean birth (odds ratio [OR], 1.4; 95% confidence interval [CI], 1.1-1.7), pharmacologic pain management (OR, 1.3; 95% CI, 1.02-1.7), continuous fetal heart rate monitoring (OR. 1.4; 95% CI, 1.2-1.8), and episiotomy (OR, 1.4; 95% CI, 1.1-1.7). Nulliparity was also associated with minimal maternal satisfaction (OR, 1.3; 95% CI, 1.0-1.5). Greater satisfaction was associated with accompaniment by a companion of choice during labor (OR, 0.49: 95% CI, 0.40-0.60). This study is one of the first to provide empirical evidence that maternal patient satisfaction is negatively affected by many common obstetric procedures in the Latin American context. These findings are consistent with World Health Organization recommendations regarding judicious and necessary, rather than routine, use of obstetric interventions.

Use of the Robson classification to assess caesarean section trends in 21 countries: a secondary analysis of two WHO multicountry surveys.

Rates of caesarean section surgery are rising worldwide, but the determinants of this increase, especially in low-income and middle-income countries, are controversial. In this study, we aimed to analyse the contribution of specific obstetric populations to changes in caesarean section rates, by using the Robson classification in two WHO multicountry surveys of deliveries in health-care facilities. The Robson system classifies all deliveries into one of ten groups on the basis of five parameters: obstetric history, onset of labour, fetal lie, number of neonates, and gestational age. We studied deliveries in 287 facilities in 21 countries that were included in both the WHO Global Survey of Maternal and Perinatal Health (WHOGS; 2004-08) and the WHO Multi-Country Survey of Maternal and Newborn Health (WHOMCS; 2010-11). We used the data from these surveys to establish the average annual percentage change (AAPC) in caesarean section rates per country. Countries were stratified according to Human Development Index (HDI) group (very high/high, medium, or low) and the Robson criteria were applied to both datasets. We report the relative size of each Robson group, the caesarean section rate in each Robson group, and the absolute and relative contributions made by each to the overall caesarean section rate. The caesarean section rate increased overall between the two surveys (from 26.4% in the WHOGS to 31.2% in the WHOMCS, p=0.003) and in all countries except Japan. Use of obstetric interventions (induction, prelabour caesarean section, and overall caesarean section) increased over time. Caesarean section rates increased across most Robson groups in all HDI categories. Use of induction and prelabour caesarean section increased in very high/high and low HDI countries, and the caesarean section rate after induction in multiparous women increased significantly across all HDI groups. The proportion of women who had previously had a caesarean section increased in moderate and low HDI countries, as did the caesarean section rate in these women. Use of the Robson criteria allows standardised comparisons of data across countries and timepoints and identifies the subpopulations driving changes in caesarean section rates. Women who have previously had a caesarean section are an increasingly important determinant of overall caesarean section rates in countries with a moderate or low HDI. Strategies to reduce the frequency of the procedure should include avoidance of medically unnecessary primary caesarean section. Improved case selection for induction and prelabour caesarean section could also reduce caesarean section rates. None.

Variation in referrals to secondary obstetrician-led care among primary midwifery care practices in the Netherlands: a nationwide cohort study.

BackgroundThe primary aim of this study was to describe the variation in intrapartum referral rates in midwifery practices in the Netherlands. Secondly, we wanted to explore the association between the practice referral rate and a woman’s chance of an instrumental birth (caesarean section or vaginal instrumental birth).MethodsWe performed an observational study, using the Dutch national perinatal database. Low risk births in all primary care midwifery practices over the period 2008–2010 were selected. Intrapartum referral rates were calculated. The referral rate among nulliparous women was used to divide the practices in three tertile groups. In a multilevel logistic regression analysis the association between the referral rate and the chance of an instrumental birth was examined.ResultsThe intrapartum referral rate varied from 9.7 to 63.7 percent (mean 37.8; SD 7.0), and for nulliparous women from 13.8 to 78.1 percent (mean 56.8; SD 8.4). The variation occurred predominantly in non-urgent referrals in the first stage of labour. In the practices in the lowest tertile group more nulliparous women had a spontaneous vaginal birth compared to the middle and highest tertile group (T1: 77.3%, T2:73.5%, T3: 72.0%). For multiparous women the spontaneous vaginal birth rate was 97%. Compared to the lowest tertile group the odds ratios for nulliparous women for an instrumental birth were 1.22 (CI 1.16-1.31) and 1.33 (CI 1.25-1.41) in the middle and high tertile groups. This association was no longer significant after controlling for obstetric interventions (pain relief or augmentation).ConclusionsThe wide variation between referral rates may not be explained by medical factors or client characteristics alone. A high intrapartum referral rate in a midwifery practice is associated with an increased chance of an instrumental birth for nulliparous women, which is mediated by the increased use of obstetric interventions. Midwives should critically evaluate their referral behaviour. A high referral rate may indicate that more interventions are applied than necessary. This may lead to a lower chance of a spontaneous vaginal birth and a higher risk on a PPH. However, a low referral rate should not be achieved at the cost of perinatal safety.

Obstetric Variation, Intervention, and Outcomes: Doing More but Accomplishing Less

Obstetric interventions, particularly induction of labor and cesarean section, are done more and more commonly, although there is a wide variation between hospitals and practitioners in specific rates. This degree of variation implies imprecision and uncertainty about diagnoses and indicated management. Although the net result of this variation has been a "more is better" approach leading to increasing use of obstetric interventions, little evidence of commensurate improvements in outcome is available. A combined package of using currently available evidence, formulating best practices, instituting regular review and feedback to hospitals and practitioners about intervention rates, and a public health approach to educate women has the potential to achieve an acceptable balance between when intervention in the labor and delivery process is warranted and when it is unnecessary.

Is There an Increase of Postpartum Hemorrhage, and Is Severe Hemorrhage Associated With More Frequent Use of Obstetric Interventions?

ABSTRACTPostpartum hemorrhage is a major complication associated with pregnancy and delivery and is a leading cause of maternal morbidity and mortality. A number of recent studies have reported an increasing incidence of severe postpartum hemorrhage. It has been suggested that the increased frequenc
