A ten-year study of midwife-led care at an Austrian tertiary care center: a retrospective analysis with special consideration of perineal trauma

Differences in rates of severe perineal trauma between midwife-led and obstetrician-led care in the Netherlands: A nationwide cohort study

Objective

To investigate trends and rates of severe perineal trauma (SPT), also known as obstetric anal sphincter injury (OASI), between midwife-led and obstetrician-led care in the Netherlands, and factors associated with SPT.

Methods

This nationwide cohort study included registry data from 2000 to 2019 (n = 2,169,950) of spontaneous vaginal births of term, live, cephalic, single infants, without a (previous) caesarean section or assisted vaginal birth.First, trends of SPT and episiotomy were shown. Second, differences in SPT rates between midwife- and obstetrician-led care were assessed. Third, associations of care factors with SPT were examined. Multivariable logistic regression analyses were used to determine which factors were important in the associations. All outcomes were stratified for parity.

Results

Over time, the SPT incidence increased mainly in midwife-led care and episiotomy rates decreased. Compared to midwife-led care, SPT rates were lower in obstetrician-led care among primiparous women (aOR 0.78; 99 % CI 0.74-0.81) and comparable among multiparous women (aOR 1.04; 99 % CI 0.99-1.10). Among women without epidural analgesia, these differences were smaller for primiparous women (aOR 0.88; 99 % CI 0.84-0.92), but the SPT rate was higher in obstetrician-led care among multiparous women (aOR 1.09; 99 % CI 1.03-1.15). Among women without shoulder dystocia, induction, augmentation, and pain medication, SPT rates were comparable among primiparous women, but higher among multiparous women in obstetrician-led care. In midwife-led care, SPT occurred more often among hospital versus home births. In obstetrician-led care, lower SPT incidences were found among births with epidural analgesia and for multiparous women with induction or augmentation.

Conclusions

Iinduction, augmentation, and epidural analgesia in obstetrician-led care may be an explanatory factor for the higher incidence of SPT among primiparous women in midwife-led care. More research is needed to explain differences in SPT rates and to understand how SPT can be prevented, while maintaining a high intact perineum rate.

Lithuanian midwives' attitudes and actions during low-risk birth

INTRODUCTION

This study sheds light on the attitudes and practices of Lithuanian midwives during low-risk births. The aim is to reveal how autonomous work is incorporated into daily routines, how care is oriented towards the mother, and how care is delivered before and during interventions. It highlights midwives' views on both their own and their colleagues' actions during labor, what is aimed for and what outcome is expected.

METHODS

A qualitative research method was chosen. Midwives were interviewed individually in February and April 2022 by random sampling and semi-structured interviews, after the purpose of the survey was explained and their consent was given to use the information only for scientific work purposes. Midwives were recruited through social networks, sharing information about the study and its nature. All data were coded and analyzed in aggregate form. Ten midwives working in the labor ward participated in the study.

RESULTS

From the midwives' point of view, every birth and its experience are unique. Midwives work together with mothers to achieve the common goal of a positive birth experience. Communication with the mother and her family, good rapport, clear information and informed decision-making are key aspects for midwives during labor. The midwife's actions must be reasonable and purposeful, with a preference for non-medicated methods of pain and stress relief.

CONCLUSIONS

A low-risk birth that is within the competence of midwives is one in which there is a low likelihood of medical interventions. Midwives are encouraged to minimize the use of interventions and to provide high quality delivery care.

Birth during off-hours: Impact of time of birth, staff´s seniority, and unit volume on maternal adverse outcomes-a population-based cross-sectional study of 87 065 deliveries

BACKGROUND

The aim of this study was to investigate whether time of birth, unit volume, and staff seniority impact the incidence of maternal complications in deliveries ≥34 + 0 gestational weeks.

METHODS

We conducted a population-based cross-sectional study of 87 065 deliveries occurring between 2004 and 2015 in ten public hospitals in Styria, Austria. A composite adverse maternal outcome measure of uterine atony, postpartum hysterectomy, postpartum bleeding, impaired wound healing, postpartum infections requiring antibiotic treatment, sepsis, or maternal death was used to compare outcomes by time of birth, unit volume, and staff seniority. Based on delivery data, generalized estimating equations (GEEs) were used to calculate the risk of maternal adverse outcomes.

RESULTS

Maternal adverse events occurred in 1.33% of deliveries. Incidence of maternal adverse events was highest for units with >1000 deliveries (adjusted OR 1.40; CI 95%: 1.16-1.69) and higher for perinatal centers (adjusted OR 1.35; CI 95%: 1.15-1.57) compared with reference units (500-1000 deliveries/year). Delivery during the daytime compared with the afternoon and nighttime did not affect the incidence of maternal complications (P = 0.765 and P = 0.136, respectively). Compared with resident-guided deliveries, the odds ratio for an adverse event was the same when a consultant attended the delivery (adjusted OR 1.13; CI 95%: 0.98-1.30) but lower in deliveries managed by midwives only (adjusted OR 0.21; CI 95%: 0.07-0.64).

CONCLUSION

Procedures performed during the night shift were not associated with increased complication rates. Delivery volume and high-volume centers were associated with the highest risk of maternal complications, and units with 500-1000 deliveries per year were the lowest. With increasing odds of pregnancy risks, these results change, and delivering in a high-volume center becomes at least as safe as delivering in a smaller unit.

Spontaneous Perineal Trauma during Non-Operative Childbirth—Retrospective Analysis of Perineal Laceration Risk Factors

Childbirth-related perineal trauma (CRPT) is defined as damage to the skin, muscles of the perineum, as well as to the anal sphincter complex and anal epithelium. The aim of the study was to analyze the risk factors for spontaneous injuries to the soft tissues of the birth canal during non-operative delivery. This was a single-center retrospective case-control study. The study included the analysis of two groups, the study group featured 7238 patients with spontaneous perineal laceration (any degree of perineal laceration) and the control group featured patients without perineal laceration with 7879 cases. The analysis of single-factor logistic regression showed that the factors related to perineal laceration during childbirth are the age of the patients giving birth (p = 0.000), the BMI before delivery (p = 0.000), the number of pregnancies (p = 0.000) and deliveries (p = 0.000), diagnosed gestational diabetes (p = 0.046), home birth (p = 0.000), vaginal birth after cesarean (VBAC) (p = 0.001), the use of oxytocin in the second stage of childbirth (p = 0.041), the duration of the second stage of childbirth (p = 0.000), body weight (p = 0.000), and the circumference of the newborn head (p = 0.000). Independent factors that increase the risk of perineal laceration during childbirth are an older age of the woman giving birth, a history of cesarean section, a higher birth weight of the newborn, and factors that reduce the risk of spontaneous perineal trauma are a higher number of deliveries and home birth.

Effects of Cognitive Nursing Combined with Continuous Nursing on Postpartum Mental State and Rehabilitation

Purpose

This study is aimed at exploring the effects of cognitive nursing combined with continuous nursing on postpartum mental state and rehabilitation.

Methods

Totally, 124 puerperas admitted to our hospital from January 2019 to January 2020 were selected and divided into a research group and a control group according to different nursing methods, with 62 cases in each group. The control group received routine care, while the research group received cognitive nursing combined with continuous nursing on this basis. The mental state, rehabilitation indicators, quality of life, incidence of complications, and nursing satisfaction were compared between the two groups after intervention.

Results

Before nursing, there was no statistically significant difference in the SAS and SDS scores between the two groups (P > 0.05); after intervention, the SAS and SDS scores of the two groups were significantly reduced, and those of the research group were lower than those of the control group (P < 0.05). After intervention, the time of the first breastfeeding, duration of lochia rubra, length of hospital stay, and score of uterine contraction pain of the research group were lower than those of the control group (P < 0.05); the psychological function, physical function, material life, and social function scores of the research group were higher than those of the control group (P < 0.05); the incidence of complications in the research group was 4.84%, lower than 20.97% in the control group (P < 0.05); the nursing satisfaction of the research group was 96.77%, which was significantly higher than 83.87% in the control group (P < 0.05).

Conclusions

Cognitive nursing combined with continuous nursing can effectively improve the mental state, shorten the length of hospital stay, increase the perceived well-being, and promote the physical rehabilitation in puerperas, which is worth promoting in clinical practice.

A comparison between midwifery and obstetric care at birth in Spain: Across-sectional study of perinatal outcomes

BACKGROUND

The organizational structure of maternity services determines the choice of which professionals provide care during pregnancy, birth, and the postnatal period, and it influences the kind of care they deliver and the level of continuity of care offered. There is considerable evidence that demonstrates a relationship between how care is provided and the maternal and neonatal health outcomes. Registered midwives and obstetricians provide maternity care across Spain. To date, no studies have assessed whether maternity outcomes differ between these two groups.

OBJECTIVE

The aim of this study was to examine the association between the care received (midwifery care versus obstetric care) and the maternal and neonatal outcomes in women with normal, low- and medium-risk pregnancies in Spain from 2016 to 2019.

DESIGN

A prospective, multicentre, cross-sectional study was carried out as part of COST Action IS1405 at 44 public hospitals in Spain in the years 2016-2019. The protocol can be accessed through the registry ISRCTN14062994. The sample size of this study was 11,537 women. The primary outcome was mode of birth. The secondary outcomes included augmentation with oxytocin, use of epidural analgesia, women's position at birth, perineal integrity, third stage of labour management, maternal and neonatal admission to intensive care, Apgar score, neonatal resuscitation, and early initiation of breastfeeding. Chi-square tests for categorical variables and independent sample t-test for continuous variables to assess differences between the midwifery and obstetric groups were calculated. Odds ratio with intervals of confidence at 95% were calculated for obstetric interventions and perinatal outcomes. A multivariate logistic regression model was applied in order to examine the effect of type of healthcare provider on perinatal outcomes. These models were adjusted for care provider, type of onset of labour, use of anaesthesia, pregnancy risk, maternal age, parity, and gestational age at birth.

RESULTS

Midwifery care was associated with lower rates of operative births and severe perineal damage and had no higher adverse outcomes. No statistically significant differences were observed in the use of other obstetric interventions between the two groups.

CONCLUSIONS

The findings of this study should encourage a shift in the current maternity care system towards a greater integration of midwifery-led services in order to achieve optimal birth outcomes for women and newborns.

Obstetrician involvement in planned midwife-led births: a cohort study in an obstetric department of a University Hospital in Switzerland

Background

Healthy women with low risk singleton pregnancies are offered a midwife-led birth model at our department. Exclusion criteria for midwife-led births include a range of abnormalities in medical history and during the course of pregnancy. In case of complications before, during or after labor and birth, an obstetrician is involved. The purpose of this study was 1) to evaluate the frequency of and reasons for secondary obstetrician involvement in planned midwife-led births and 2) to assess the maternal and neonatal outcome.

Methods

We analyzed a cohort of planned midwife-led births during a 14 years period (2006-2019). Evaluation included a comparison between midwife-led births with or without secondary obstetrician involvement, regarding maternal characteristics, birth mode, and maternal and neonatal outcome. Statistical analysis was performed by unpaired t-tests and Chi-square tests.

Results

In total, there were 532 intended midwife-led births between 2006 and 2019 (2.6% of all births during this time-period at the department). Among these, 302 (57%) women had spontaneous vaginal births as midwife-led births. In the remaining 230 (43%) births, obstetricians were involved: 62% of women with obstetrician involvement had spontaneous vaginal births, 25% instrumental vaginal births and 13% caesarean sections. Overall, the caesarean section rate was 5.6% in the whole cohort of women with intended midwife-led births. Reasons for obstetrician involvement primarily included necessity for labor induction, abnormal fetal heart rate monitoring, thick meconium-stained amniotic fluid, prolonged first or second stage of labor, desire for epidural analgesia, obstetrical anal sphincter injuries, retention of placenta and postpartum hemorrhage. There was a significantly higher rate of primiparous women in the group with obstetrician involvement. Arterial umbilical cord pH < 7.10 occurred significantly more often in the group with obstetrician involvement, while 5′ Apgar score < 7 did not differ significantly. The overall transfer rate of newborns to neonatal intensive care unit was low (1.3%).

Conclusion

A midwife-led birth in our setting is a safe alternative to a primarily obstetrician-led birth, provided that selection criteria are being followed and prompt obstetrician involvement is available in case of abnormal course of labor and birth or postpartum complications.

Beyond the "information deficit model" - understanding vaccine-hesitant attitudes of midwives in Austria: a qualitative study

BACKGROUND

Healthcare workers are considered key stakeholders in efforts to address vaccine hesitancy. Midwives' influence in advising expectant parents on early-childhood vaccinations is unquestioned, yet they remain an understudied group. The literature on midwives' attitudes towards vaccinations is also inconclusive. We therefore conducted an explorative qualitative study on midwives' vaccine-hesitant attitudes towards MMR (measles-mumps-rubella) vaccinations in Austria.

METHODS

We conducted 12 in-depth interviews on their knowledge, concerns, and beliefs with midwives who self-identified as hesitant or resistant towards early-childhood MMR vaccinations. We analyzed the data using a grounded theory approach to distill common themes and meanings.

RESULTS

Healthcare workers' stewardship to address vaccine hesitancy is commonly framed in terms of the "information deficit model": disseminate the right information and remedy publics' information deficits. Our findings suggest that this approach is too simplistic: Midwives' professional self-understanding, their notions of "good care" and "good parenthood" inflect how they engage with vaccine information and how they address it to their clients. Midwives' model of care prioritized good counseling rather than sharing scientific information in a "right the wrong"-manner. They saw themselves as critical consumers of that information and as promoting "empowered patients" who were free, and affluent enough, to make their own choices about vaccinations. In so doing, they also often promoted traditional notions of motherhood.

CONCLUSIONS

Research shows that, for parents, vaccine decision-making builds on trust and dialogue with healthcare professionals and is more than a technical issue. In order to foster these interactions, understanding healthcare professionals' means of engaging with information is key to understanding how they engage with their constituents. Healthcare workers are more than neutral resources; their daily praxis influenced by their professional standing in the healthcare system. Similarly, healthcare professionals' views on vaccinations cannot be remedied with more information either. Building better and more diverse curricula for different groups of healthcare workers must attend to their respective roles, ethics of care, and professional beliefs. Taken together, better models for addressing vaccine hesitancy can only be developed by espousing a multi-faceted view of decision-making processes and interactions of healthcare workers with constituents.

Factors associated with the performance of episiotomy

OBJECTIVE

To analyze the factors associated with the performance of episiotomy.

METHODS

Cross-sectional study, developed with data from the research "Born in Belo Horizonte: Labor and birth survey, "conducted with 577 women who had their children via vaginal birth. In order to verify the magnitude of the association between episiotomy and its possible determinants, logistic regression models were constructed to estimate the odds ratio.

RESULTS

Episiotomy was performed in 26.34% of women, and 59.21% knew they had been subjected to it. We observed that younger women, primiparous women, women assisted by a professional other than the obstetric nurse and women who had their babies in a private hospital have an increased chance of being submitted to this procedure.

CONCLUSION

Considering the rates of episiotomy, this study highlights the need for the absolute contraindication to indiscriminate performing it.

'No Austrian Mother Does This to Sleep Without a Baby!' Postnatal Acculturative Stress and 'Doing the Month' Among East Asian Women in Austria: Revisiting Acculturation Theories From a Qualitative Perspective

Acculturative stress is a phenomenon describing negative emotions experienced by immigrants in their socio-cultural and psychological adaptation process to the host society’s dominant culture and its population. Acculturative stress is assumed to be one the reasons for higher prevalence of postnatal depression among immigrant women compared to non-immigrant women. Theories and models of acculturation and coping strategies suggest that certain cultural orientations or behaviors could mitigate acculturative stress and postnatal depression. Nevertheless, quantitative studies applying these theories have so far revealed inconsistent results. Given this background, we ask: what can a qualitative study of immigrant women’s postnatal experiences tell us about the interrelationships between immigrant mothers’ acculturation behaviors or cultural orientations, and maternal psychological health? Particularly, we explore the postnatal experiences of Chinese and Japanese women who gave birth in Austria, focusing on their experiences and behaviors influenced by their heritage culture’s postnatal practices (zuò yuè zi and satogaeri). Theoretically, we apply Berry’s acculturation model through a focus on what we call ‘Postnatal Acculturative Stress’ (PAS). By doing so, we identify factors that prevent or mitigate PAS. Another aim of this article is to critically reassess Berry’s model in the context of postnatal care and maternal psychological health. Data were analyzed using a combination of deductive and inductive method through the application of directed content analysis and phenomenological approach. Women’s postnatal experiences were summarized as an ‘unexpected solitary struggle in the midst of dual identity change’ in four specific domains: postnatal rest and diet, social support, feelings toward significant others and identity. Preventive and mitigating factors against PAS included trust (in self and one’s health beliefs) and mutual respectful relationships with and between the significant others. The application of Berry’s acculturation model provided a useful framework of analysis. Nevertheless, the multifarious complexity involved in the process of acculturation as well as different power dynamics in the family and healthcare settings makes it difficult to draw causal relationships between certain acculturation behaviors or cultural orientations with specific health outcomes. Health professionals should be aware of the complex psychosocial processes, contexts as well as social environment that shape immigrants’ acculturative behaviors.

Maternal and neonatal outcome of births planned in alongside midwifery units: a cohort study from a tertiary center in Germany

Background

For healthy women entering birth after uneventful pregnancy, midwife-led models of care have the potential to reduce interventions and increase the vaginal birth rate. In Germany, 98.4% of women are giving birth in consultant-led obstetric units. Alongside midwifery units (AMU) have been established in 2003. We compared the outcome of women registered for planned birth in the AMU at our hospital with a matched group of low-risk women who gave birth in standard obstetric care during the same period of time.

Methods

We used a retrospective cohort study design. The study group consisted of all women admitted to labor ward who had registered for birth in AMU from 2010 to 2017. For the control group, low-risk women were selected; additionally, matching was performed for parity. Mode of birth was chosen as primary outcome parameter for the mother. For the neonate, a composite primary outcome (5-min Apgar < 7 or umbilical cord arterial pH < 7.10 or transfer to specialist neonatal care) was defined. Secondary outcomes included epidural anesthesia, duration of the second stage of labor, episiotomy, obstetric injury, and postpartum hemorrhage. Non-inferiority was assessed, and multiple logistic regression analysis was performed.

Results

Six hundred twelve women were admitted for labor in AMU, the control group consisted of 612 women giving birth in standard obstetric care. Women in the study group were on average older and had a higher body mass index (BMI); birthweight was on average 95 g higher. Non-inferiority could be established for the primary outcome parameters. Epidural anesthesia and episiotomy rates were lower, and the mean duration of the second stage of labor was shorter in the study group; second-degree perineal tears were less common, higher-order obstetric lacerations occurred more frequently.

Overall, 50.3% of women were transferred to standard obstetric care. Regression analysis revealed effects of parity, age and birthweight on the chance of transfer.

Conclusion

Compared to births in our consultant-led obstetric unit, the outcome of births planned in the AMU was not inferior, and intervention rates were lower. Our results support the integration of AMU as a complementary model of care for low-risk women.

Are women attending a midwifery-led birthing center at increased risk of anal sphincter injury?

INTRODUCTION AND HYPOTHESIS

In recent years there has been renewed interest in midwifery-led care for women, with studies reporting similar neonatal outcomes despite lower rates of intervention in midwifery-led birthing centers. Research into obstetric anal sphincter injuries (OASI) in these birthing centers is scarce. The objective of this study was to compare the rate of OASI after spontaneous vaginal delivery in nulliparous women in consultant or midwifery-led units over a ten-year period.

METHODS

All spontaneous vaginal deliveries in nulliparous women from 2008 to 2017 were analyzed in a single-center retrospective study. Women who had neuraxial analgesia were excluded. The primary endpoint was OASI. Labor characteristics in both groups were compared, and a multiple regression model was created.

RESULTS

During the study period, there were 3260 spontaneous vaginal deliveries in nulliparous women; 75.7% (2467/3260) delivered in the consultant-led unit and 24.3% (793/3260) in the midwifery-led unit (MLU). Women delivering in the MLU had a greater risk of anal sphincter injury than those delivering in the CLU (4.9% [39/793] vs 2.5% [62/2467], OR 2.01, 95% CI 1.32 - 3.01). Significant risk factors that increased the risk of OASI on regression analysis were birthweight and delivery in the midwifery-led unit.

CONCLUSIONS

Women delivering in the midwifery-led unit appear to be at double the risk of OASI when compared to those delivering in the consultant-led unit. These results are in contrast to previous studies in midwifery-led centers. This difference may be site-specific and further research is required before these results form part of patient counseling.

Intrapartum and neonatal mortality in low-risk term women in midwife-led care and obstetrician-led care at the onset of labor: A national matched cohort study

INTRODUCTION

Midwife-led models of care have been the subject of debate for many years. We conducted a study to compare intrapartum and neonatal mortality rates in midwife-led (primary) vs obstetrician-led (secondary) care at the onset of labor in low-risk term women.

MATERIAL AND METHODS

We performed an unmatched and a propensity score matched cohort study using data from the national perinatal audit registry (PAN) and from the national perinatal registry (PERINED) of the Netherlands. We included women with singleton pregnancies (without congenital anomalies or antepartum fetal death) who gave birth at term between 2010 and 2012. We excluded the following major risk factors: non-vertex position of the fetus, previous cesarean birth, hypertension, diabetes mellitus, prolonged rupture of membranes (≥24 hours), vaginal bleeding in the second half of pregnancy, nonspontaneous start of labor and post-term pregnancy (≥42 weeks). The primary outcome was intrapartum or neonatal mortality up to 28 days after birth. Secondary outcome measures were mode of delivery and a 5-minute Apgar score <7.

RESULTS

We included 259 211 women. There were 100/206 642 (0.48‰) intrapartum and neonatal deaths in the midwife group and 23/52 569 (0.44‰) in the obstetrician group (odds ratio [OR] 1.11, 95% CI 0.70-1.74). Propensity score matched analysis showed mortality rates of 0.49‰ (26/52 569) among women in midwife-led care and 0.44‰ (23/52 569) for women in obstetrician-led care (OR 1.13, 95% CI 0.65-1.98). In the midwife group there were significantly lower rates of vaginal instrumental deliveries (8.4% vs 13.0%; matched OR 0.65, 95% CI 0.62-0.67) and intrapartum cesarean sections (2.6% vs 8.2%; matched OR 0.32, 95% CI 0.30-0.34), and fewer neonates with low Apgar scores (<7 after 5 minutes) (0.69% vs 1.11%; matched OR 0.61, 95% CI 0.53-0.69).

CONCLUSIONS

Among low-risk term women, there were comparable intrapartum and neonatal mortality rates for women starting labor in midwife-led vs obstetrician-led care, with lower intervention rates and fewer low Apgar scores in the midwife group.

Utility of the 5-Minute Apgar Score as a Research Endpoint

Although Apgar scores are commonly used as proxy outcomes, little evidence exists in support of the most common cutpoints (<7, <4). We used 2 data sets to explore this issue: one contained planned community births from across the United States (n = 52,877; 2012-2016), and the other contained hospital births from California (n = 428,877; 2010). We treated 5-minute Apgars as clinical "tests," compared against 18 known outcomes; we calculated sensitivity, specificity, positive and negative predictive values, and the area under the receiver operating characteristic curve for each. We used 3 different criteria to determine optimal cutpoints. Results were very consistent across data sets, outcomes, and all subgroups: The cutpoint that maximizes the trade-off between sensitivity and specificity is universally <9. However, extremely low positive predictive values for all outcomes at <9 indicate more misclassification than is acceptable for research. The areas under the receiver operating characteristic curves (which treat Apgars as quasicontinuous) were generally indicative of adequate discrimination between infants destined to experience poor outcomes and those not; comparing median Apgars between groups might be an analytical alternative to dichotomizing. Nonetheless, because Apgar scores are not clearly on any causal pathway of interest, we discourage researchers from using them unless the motivation for doing so is clear.

Induction of labour at 41 weeks versus expectant management until 42 weeks (INDEX): multicentre, randomised non-inferiority trial

OBJECTIVE

To compare induction of labour at 41 weeks with expectant management until 42 weeks in low risk women.

DESIGN

Open label, randomised controlled non-inferiority trial.

SETTING

123 primary care midwifery practices and 45 hospitals (secondary care) in the Netherlands, 2012-16.

PARTICIPANTS

1801 low risk women with an uncomplicated singleton pregnancy: randomised to induction (n=900) or to expectant management until 42 weeks (n=901).

INTERVENTIONS

Induction at 41 weeks or expectant management until 42 weeks with induction if necessary.

PRIMARY OUTCOME MEASURES

Primary outcome was a composite of perinatal mortality and neonatal morbidity (Apgar score <7 at five minutes, arterial pH <7.05, meconium aspiration syndrome, plexus brachialis injury, intracranial haemorrhage, and admission to a neonatal intensive care unit (NICU). Secondary outcomes included maternal outcomes and mode of delivery. The null hypothesis that expectant management is inferior to induction was tested with a non-inferiority margin of 2%.

RESULTS

Median gestational age at delivery was 41 weeks+0 days (interquartile range 41 weeks+0 days-41 weeks+1 day) for the induction group and 41 weeks+2 days (41 weeks+0 days-41 weeks+5 days) for the expectant management group. The primary outcome was analysed for both the intention-to-treat population and the per protocol population. In the induction group, 15/900 (1.7%) women had an adverse perinatal outcome versus 28/901 (3.1%) in the expectant management group (absolute risk difference -1.4%, 95% confidence interval -2.9% to 0.0%, P=0.22 for non-inferiority). 11 (1.2%) infants in the induction group and 23 (2.6%) in the expectant management group had an Apgar score <7 at five minutes (relative risk (RR) 0.48, 95% CI 0.23 to 0.98). No infants in the induction group and three (0.3%) in the expectant management group had an Apgar score <4 at five minutes. One fetal death (0.1%) occurred in the induction group and two (0.2%) in the expectant management group. No neonatal deaths occurred. 3 (0.3%) neonates in the induction group versus 8 (0.9%) in the expectant management group were admitted to an NICU (RR 0.38, 95% CI 0.10 to 1.41). No significant difference was found in composite adverse maternal outcomes (induction n=122 (13.6%) v expectant management n=102 (11.3%)) or in caesarean section rate (both groups n=97 (10.8%)).

CONCLUSIONS

This study could not show non-inferiority of expectant management compared with induction of labour in women with uncomplicated pregnancies at 41 weeks; instead a significant difference of 1.4% was found for risk of adverse perinatal outcomes in favour of induction, although the chances of a good perinatal outcome were high with both strategies and the incidence of perinatal mortality, Apgar score <4 at five minutes, and NICU admission low.

Associations with perineal trauma during childbirth at home and in health facilities in indigenous municipalities in southern Mexico: a cross-sectional cluster survey

BACKGROUND

Episiotomy and perineal tears remain common in vaginal deliveries. This study estimated the frequency of and factors associated with perineal tears, episiotomies, and postnatal infections among women in two predominantly indigenous municipalities in southern Mexico, where traditional midwives play an important role in women's health.

METHODS

A cross-sectional study contacted women who gave birth in the previous three years. An administered questionnaire asked about place of delivery, birthing position, birth attendant, episiotomy, perineal tears, and wound infection after delivery. Cluster adjusted bivariate and then multivariate analysis examined factors potentially associated with self-reported perineal trauma (episiotomy and/or perineal tear). Key informant interviews sought insights into some of the findings.

RESULTS

Among women with a vaginal delivery, 71% (876/1238) of indigenous women and 18% (36/197) of non-indigenous women delivered at home. Some 17% (247/1416) of women overall, and 33% (171/525) of those delivering in a health facility, reported an episiotomy during delivery. Among 171 women reporting an episiotomy in a health facility, 30% (52) also reported a perineal tear. Overall, 13% (190/1412) of women reported they had a perineal tear during delivery, 17% (86/515) of those delivering in a health facility and 12% (104/897) of those delivering at home. A quarter of the women had self-reported perineal trauma during their last delivery, 38% (196/511) of those delivering in a health facility and 18% (160/893) of those delivering at home. In bivariate analysis, indigenous ethnicity, home delivery, upright posture in labour, and delivery by a traditional midwife were associated with a lower risk of perineal trauma, while primiparas had a higher risk. In the final multivariate model, delivery by a traditional midwife was protective (ORa 0.41, 95%CIca 0.32-0.54) and primiparity was a risk factor (ORa 2.01, 95%CIca 1.5-2.68) for perineal trauma. Women suggested that fear of bad treatment and being cut made them unwilling to deliver in health facilities.

CONCLUSIONS

The rate of perineal trauma among women giving birth in indigenous communities could be reduced by efforts to decrease the use of episiotomies in health facilities, and by opening a dialogue with traditional midwives to increase their interaction with formal health services.
