RESUMEN

INTRODUCTION: while pregnancy is a very beautiful and memorable experience for most women, some women may experience apathy towards childbirth and have feelings of fear and anxiety (tocophobia). Tocophobia can be far reaching with adverse physiologic and emotional consequences for mothers, infants and families. This study therefore explored tocophobia experiences among primigravid women and explored its influence on birth choices among antenatal women. METHODS: the study employed a qualitative exploratory research design. Participants who were primigravida (women who had never experienced childbirth), were selected using purposive sampling technique on antenatal clinic days. Data was obtained using semi-structured interview questions. Data was analyzed using content analysis approach and thematic categorization. RESULTS: results showed that few of the women experienced tocophobia and these fears were not strong enough to make them opt for caesarian section. Reasons attributed to tocophobia experience among the participants included "horror stories" told in the neighborhood, "past experiences" of close acquaintance and "entertainment videos" broadcast. Furthermore, all the participants preferred to have vaginal delivery. CONCLUSION: few of the primigravid women in Ekiti State, Nigeria, experience tocophobia and this experience does not influence their choice of delivery option, as all participant´s preferred vaginal delivery to caesarian section. It is important for midwives to be aware of their role in counselling and identifying women with tocophobia in order to promote good and safe transition from pregnancy to motherhood.

RESUMEN

OBJECTIVE: To describe rates of maternal and perinatal birth outcomes for community births and to compare outcomes by planned place of birth (home vs state-licensed, freestanding birth center) in a Washington State birth cohort, where midwifery practice and integration mirrors international settings. METHODS: We conducted a retrospective cohort study including all births attended by members of a statewide midwifery professional association that were within professional association guidelines and met eligibility criteria for planned birth center birth (term gestation, singleton, vertex fetus with no known fluid abnormalities at term, no prior cesarean birth, no hypertensive disorders, no prepregnancy diabetes), from January 1, 2015 through June 30, 2020. Outcome rates were calculated for all planned community births in the cohort. Estimated relative risks were calculated comparing delivery and perinatal outcomes for planned births at home to state-licensed birth centers, adjusted for parity and other confounders. RESULTS: The study population included 10,609 births: 40.9% planned home and 59.1% planned birth center births. Intrapartum transfers to hospital were more frequent among nulliparous individuals (30.5%; 95% CI 29.2-31.9) than multiparous individuals (4.2%; 95% CI 3.6-4.6). The cesarean delivery rate was 11.4% (95% CI 10.2-12.3) in nulliparous individuals and 0.87% (95% CI 0.7-1.1) in multiparous individuals. The perinatal mortality rate after the onset of labor (intrapartum and neonatal deaths through 7 days) was 0.57 (95% CI 0.19-1.04) per 1,000 births. Rates for other adverse outcomes were also low. Compared with planned birth center births, planned home births had similar risks in crude and adjusted analyses. CONCLUSION: Rates of adverse outcomes for this cohort in a U.S. state with well-established and integrated community midwifery were low overall. Birth outcomes were similar for births planned at home or at a state-licensed, freestanding birth center.

RESUMEN

BACKGROUND: Many women experience fear of childbirth (FOC). While fears about childbirth may be normal during pregnancy, some women experience high to severe FOC. At the extreme end of the fear spectrum is tocophobia, which is considered a specific condition that may cause distress, affect well-being during pregnancy and impede the transition to parenthood. Various interventions have been trialled, which support women to reduce and manage high to severe FOC, including tocophobia. OBJECTIVES: To investigate the effectiveness of non-pharmacological interventions for reducing fear of childbirth (FOC) compared with standard maternity care in pregnant women with high to severe FOC, including tocophobia. SEARCH METHODS: In July 2020, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), and reference lists of retrieved studies. We contacted researchers of trials which were registered and appeared to be ongoing. SELECTION CRITERIA: We included randomised clinical trials which recruited pregnant women with high or severe FOC (as defined by the individual trial), for treatment intended to reduce FOC. Two review authors independently screened and selected titles and abstracts for inclusion. We excluded quasi-randomised and cross-over trials. DATA COLLECTION AND ANALYSIS: We used standard methodological approaches as recommended by Cochrane. Two review authors independently extracted data and assessed the studies for risk of bias. A third review author checked the data analysis for accuracy. We used GRADE to assess the certainty of the evidence. The primary outcome was a reduction in FOC. Secondary outcomes were caesarean section, depression, birth preference for caesarean section or spontaneous vaginal delivery, and epidural use. MAIN RESULTS: We included seven trials with a total of 1357 participants. The interventions included psychoeducation, cognitive behavioural therapy, group discussion, peer education and art therapy. We judged four studies as high or unclear risk of bias in terms of allocation concealment; we judged three studies as high risk in terms of incomplete outcome data; and in all studies, there was a high risk of bias due to lack of blinding. We downgraded the certainty of the evidence due to concerns about risk of bias, imprecision and inconsistency. None of the studies reported data about women's anxiety. Participating in non-pharmacological interventions may reduce levels of fear of childbirth, as measured by the Wijma Delivery Expectancy Questionnaire (W-DEQ), but the reduction may not be clinically meaningful (mean difference (MD) -7.08, 95% confidence interval (CI) -12.19 to -1.97; 7 studies, 828 women; low-certainty evidence). The W-DEQ tool is scored from 0 to 165 (higher score = greater fear). Non-pharmacological interventions probably reduce the number of women having a caesarean section (RR 0.70, 95% CI 0.55 to 0.89; 5 studies, 557 women; moderate-certainty evidence). There may be little to no difference between non-pharmacological interventions and usual care in depression scores measured with the Edinburgh Postnatal Depression Scale (EPDS) (MD 0.09, 95% CI -1.23 to 1.40; 2 studies, 399 women; low-certainty evidence). The EPDS tool is scored from 0 to 30 (higher score = greater depression). Non-pharmacological interventions probably lead to fewer women preferring a caesarean section (RR 0.37, 95% CI 0.15 to 0.89; 3 studies, 276 women; moderate-certainty evidence).  Non-pharmacological interventions may increase epidural use compared with usual care, but the 95% CI includes the possibility of a slight reduction in epidural use (RR 1.21, 95% CI 0.98 to 1.48; 2 studies, 380 women; low-certainty evidence). AUTHORS' CONCLUSIONS: The effect of non-pharmacological interventions for women with high to severe fear of childbirth in terms of reducing fear is uncertain. Fear of childbirth, as measured by W-DEQ, may be reduced but it is not certain if this represents a meaningful clinical reduction of fear. There may be little or no difference in depression, but there may be a reduction in caesarean section delivery. Future trials should recruit adequate numbers of women and measure birth satisfaction and anxiety.

RESUMEN

Abstract Objectives: describe mothers, pregnancies and newborns' characteristics according to the type of childbirth history and to analyze repeated cesarean section (RCS) and vaginal delivery after cesarean section (VBACS), in São Paulo State in 2012. Methods: data are from the Sistema de Informações sobre Nascidos Vivos (Live Birth Information Systems). To find the RCS's group, the current type of childbirth equal to cesarean section was selected and from these all the previous cesareans. To identify the VBACS's group all live birth with current vaginal delivery were selected and from these all previous cesareans. Mothers with a history of RCS and VBACS were analyzed according to the characteristics of the pregnancy, newborn and the childbirth hospital. Results: 273,329 mothers of live birth with at least one previous child were studied. 43% of these were born of RCS and 7.4% of VBACS. Mothers who underwent RCS are older and higher educated and their newborns presented a lower incidence of low birth weight. Early term was the most frequent rating for gestational age born of RCS. Live births were of VBACS and had greater proportions of late term. The RCS was more common in hospitals not affiliated with the Sistema Único de Saúde (SUS) (Public Health System) (44.1%). Conclusion: the high RCS's rates, especially in the private sector, highlight the necessity of improvements in childbirth care model in São Paulo.


Resumo Objetivos: descrever características das mães, da gestação e do recém-nascido, segundo histórico de tipo de parto, analisando repetição de cesárea (RC) e parto vaginal após cesárea (PVAC), no Estado de São Paulo, em 2012. Métodos: os dados são provenientes do Sistema de Informações sobre Nascidos Vivos. Para encontrar o conjunto RC, selecionou-se o tipo de parto atual igual a cesárea e destes buscou-se todos com cesárea anterior. Para identificar o grupo PVAC, selecionou-se os recém-nascido com parto atual vaginal e destes buscou-se todos com cesárea anterior. Foram analisadas mães com história de RC e PVAC, segundo características da gestação, do recémnascido e hospital do parto. Resultados: estudou-se 273.329 nascidos vivos de mães com pelo menos um filho anterior. Destes, 43% nasceram por RC e 7,4% por PVAC. As mães que realizaram RC são mais velhas e mais escolarizadas, seus recém-nascidos apresentaram menor proporção de baixo peso ao nascer. Termo precoce foi a mais frequente idade gestacional dos que nasceram por RC. Os recém-nascidos por PVAC apresentaram maiores proporções de termo tardio. RC foi mais frequente nos hospitais sem vínculo com o Sistema Único de Saúde (44,1%). Conclusão: as altas taxas de RC, principalmente no setor privado, evidenciam necessidade de melhoras no modelo de atenção ao parto em São Paulo.

RESUMEN

OBJECTIVE: China has a high cesarean delivery (CD) and low labor epidural analgesia (LEA) rate. This online survey was conducted to explore the reasons behind this phenomenon and potential solutions. METHODS: A voluntary, anonymous survey was distributed via both WeChat and professional websites for 4 months amongst groups of Chinese perinatal professionals. Data was collected and analyzed using a Chi-square test and presented as percentages of respondents. RESULTS: 1412 respondents were recorded (43% anesthesiologists, 35% obstetricians, 15.5% midwives or labor and delivery nurses, and 6.5% others), and 1320 respondents were care providers. It was found that 82.7% (1092/1320) of the provider respondents used CD per patient request in fear of lawsuits or yinao/yibao and 63.4% (837/1320) used CD for respecting superstitious culture. The number one reason (noted by 60.2% (795/1320) of all the three specialties) for low LEA use was lack of anesthesia manpower without statistical difference among specialties. The most recommended solution was increasing the anesthesia workforce, proposed by 79.8% (1053/1320) of the three specialties. However, the top solution provided by the two non-anesthesia specialties is different from the one proposed by anesthesiologists. The later (83%, 504/606) suggested increasing the incentive to provide the service is more effective. The answers to questions related to medical knowledge about CD and LEA, and unwillingness of anesthesiologists, parturients and their family members to LEA were similar for the most part, while the opinions regarding low LEA use related to poor experiences and unwillingness of obstetricians and hospital administrators were significantly divided among the three specialties. In the providers' point of view, the unwillingness to LEA from parturient's family members was the most salient (26.1%, 345/1320), which is more than all care providers, hospital administrators, and parturients themselves (16.8%, 222/1320). CONCLUSION: The reasons for high CD rate and low LEA use are multifactorial. The sociological issues (fear of yinao/yibao and superstitious culture) were the top two contributing factors for the high CD rate in China, while lack of anesthesia manpower was the top response for the low LEA use, which contributes to its being the most recommended solution overall from the three specialties. An incentive approach to providers is a short-term solution while training more perinatal care providers (especially among anesthesiologists and midwives), improving billing systems, and reforming legal systems are 3 systemic approaches to tackling this problem in the long-term.

RESUMEN

BACKGROUND: Social factors associated with poor childbirth outcomes and experiences of maternity care include minority ethnicity, poverty, young motherhood, homelessness, difficulty speaking or understanding English, migrant or refugee status, domestic violence, mental illness and substance abuse. It is not known what specific aspects of maternity care work to improve the maternal and neonatal outcomes for these under-served, complex populations. METHODS: This study aimed to compare maternal and neonatal clinical birth outcomes for women with social risk factors accessing different models of maternity care. Quantitative data on pregnancy and birth outcome measures for 1000 women accessing standard care, group practice and specialist models of care at two large, inner-city maternity services were prospectively collected and analysed using multinominal regression. The level of continuity of care and place of antenatal care were used as independent variables to explore these potentially influential aspects of care. Outcomes adjusted for women's social and medical risk factors and the service attended. RESULTS: Women who received standard maternity care were significantly less likely to use water for pain relief in labour (RR 0.11, CI 0.02-0.62) and have skin to skin contact with their baby shortly after birth (RR 0.34, CI 0.14-0.80) compared to the specialist model of care. Antenatal care based in the hospital setting was associated with a significant increase in preterm birth (RR 2.38, CI 1.32-4.27) and low birth weight (RR 2.31, CI 1.24-4.32), and a decrease in induction of labour (RR 0.65, CI 0.45-0.95) compared to community-based antenatal care, this was despite women's medical risk factors. A subgroup analysis found that preterm birth was increased further for women with the highest level of social risk accessing hospital-based antenatal care (RR 3.11, CI1.49-6.50), demonstrating the protective nature of community-based antenatal care. CONCLUSIONS: This research highlights how community-based antenatal care, with a focus on continuity of carer reduced health inequalities and improved maternal and neonatal clinical outcomes for women with social risk factors. The findings support the current policy drive to increase continuity of midwife-led care, whilst adding that community-based care may further improve outcomes for women at increased risk of health inequalities. The relationship between community-based models of care and neonatal outcomes require further testing in future research. The identification of specific mechanisms such as help-seeking and reduced anxiety, to explain these findings are explored in a wider evaluation.

RESUMEN

BACKGROUND: Yoga can reduce the risk of preterm delivery, cesarean section (CS), and fetal death. The aim of the present study was to investigate the effects of Yoga on pregnancy, delivery, and neonatal outcomes. METHODS: This was a clinical trial study and using the random sampling without replacement 70 pregnant women entered Hatha Yoga and control groups according to the color of the ball they took from a bag containing two balls (blue or red). The data collection tool was a questionnaire pregnancy, delivery, and neonatal outcomes. The intervention in this study included pregnancy Hatha Yoga exercises that first session of pregnancy Yoga started from the 26th week and samples attended the last session in the 37th week. They exercised Yoga twice a week (each session lasting 75 min) in a Yoga specialized sports club. The control group received the routine prenatal care that all pregnant women receive. RESULTS: The results showed that yoga reduced the induction of labor, the episiotomy rupture, duration of labor, also had a significant effect on normal birth weight and delivery at the appropriate gestational age. There were significant differences between the first and second Apgar scores of the infants. CONCLUSION: The results of the present study showed that Yoga can improve the outcomes of pregnancy and childbirth. They can be used as part of the care protocol along with childbirth preparation classes to reduce the complications of pregnancy and childbirth. TRIAL REGISTRATION: IRCT20180623040197N2 (2019-02-11).

RESUMEN

ABSTRACT: The objective of this study was to evaluate the risk factors, pathogenic bacteria and drug sensitivity of maternal sepsis, and provide evidence for clinical prevention and treatment.A retrospective investigation of pregnant women with full-term maternal sepsis was performed to analyze the risk factors, pathogenic bacteria, and drug sensitivity of maternal sepsis.Univariate analysis showed that temperature, serum procalcitonin (PCT) and C-reactive protein (CRP) at admission, white blood cell count (WBC), PCT, CRP and neutrophilic granulocyte percentage (N%) during fever, premature rupture of membranes (PROM), antibiotic use within 1 week, mode of production, onset and duration of fever, between groups were statistically significant (P < .05). Logistic regression analysis showed that cesarean section was an independent risk factor for sepsis (OR = 11.839, 95%CI: 3.121-44.906). Apparent increase was found in body temperature (OR = 3.664, 95%CI: 1.722-7.795), duration of fever (OR = 1.953, 95%CI: 1.242-3.071), and PCT (OR = 1.080, 95%CI: 1.002-1.163). Also, increasing neutrophil ratio (OR = 1.180, 95%CI: 1.073-1.297) indicated a high possibility of maternal sepsis. The organism Escherichia coli (E. coli) was the most common pathogenic bacteria in the positive blood culture group (90%), and the sensitivity to carbapenems (meropenem and imipenem/cilastatin) was 100%, that to piperacillin-tazobactam and amoxicillin sulbactam was over 90%, and that to ceftazidime was 95%.Cesarean section was an independent risk factor for maternal sepsis in term pregnant women with positive blood culture. Besides, the E. coli was the most common pathogenic bacteria in the positive blood culture group. Antibiotics should be used in time and reasonably when the temperature was significantly increased with elevated PCT and N% after a cesarean section.

RESUMEN

BACKGROUND: Pregnancy associated cancer (PAC) may lead to adverse obstetric and neonatal outcomes. This study aims to assess the association between PACs and adverse perinatal outcomes [i.e. labor induction, iatrogenic delivery, preterm birth, small for gestational age (SGA) newborn, low Apgar score, major malformations, perinatal mortality] in Lombardy, Northern Italy. METHODS: This population-based historic cohort study used the certificate of delivery assistance and the regional healthcare utilization databases of Lombardy Region to identify beneficiaries of National Health Service who delivered between 2008 and 2017. PACs were defined through oncological ICD-9-CM codes reported in the hospital discharge forms. Each woman with PAC was matched to four women randomly selected from those cancer-free (1:4). Log-binomial regression models were fitted to estimate crude and adjusted prevalence ratio (aPR) and the corresponding 95% confidence interval (CI) of each perinatal outcome among PAC and cancer-free women. RESULTS: Out of the 657,968 deliveries, 831 PACs were identified (1.26 per 1000). PAC diagnosed during pregnancy was positively associated with labor induction or planned delivery (aPR=1.80, 95% CI: 1.57-2.07), cesarean section (aPR=1.78, 95% CI: 1.49-2.11) and premature birth (aPR=6.34, 95% CI: 4.59-8.75). No association with obstetric outcomes was found among PAC diagnosed in the post-pregnancy. No association of PAC, neither during pregnancy nor in post-pregnancy was found for SGA (aPR=0.71, 95% CI: 0.36-1.35 and aPR=1.04, 95% CI: 0.78-1.39, respectively), but newborn among PAC women had a lower birth weight (p-value< 0.001). Newborns of women with PAC diagnosed during pregnancy had a higher risk of borderline significance of a low Apgar score (aPR=2.65, 95% CI: 0.96-7.33) as compared to cancer-free women. CONCLUSION: PAC, especially when diagnosed during pregnancy, is associated with iatrogenic preterm delivery, compromising some neonatal heath indicators.

RESUMEN

The use of probiotic microorganisms in clinical practice has increased in recent years and a significant number of pregnant women are regular consumers of these products. However, probiotics might modulate the immune system, and whether or not this modulation is beneficial for perinatal outcomes is unclear. We performed a systematic review and meta-analysis to evaluate the reporting of perinatal outcomes in randomized controlled trials including women supplemented with probiotic microorganisms during pregnancy. We also analyzed the effects that the administration of probiotic microorganisms exerts on perinatal outcomes. In the review, 46 papers were included and 25 were meta-analyzed. Reporting of perinatal outcomes was highly inconsistent across the studies. Only birth weight, cesarean section, and weeks of gestation were reported in more than 50% of the studies. Random effects meta-analysis results showed that the administration of probiotic microorganisms during pregnancy did not have any a positive or negative impact on the perinatal outcomes evaluated. Subgroup analysis results at the strain level were not significantly different from main analysis results. The administration of probiotic microorganisms does not appear to influence perinatal outcomes. Nonetheless, future probiotic studies conducted in pregnant women should report probiotic strains and perinatal outcomes in order to shed light upon probiotics' effects on pregnancy outcomes.

RESUMEN

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.

RESUMEN

INTRODUCTION: Current US guidelines for the care of women with obesity generalize obesity-related risks to all women regardless of overall health status and assume that birth will occur in hospitals. Perinatal outcomes for women with obesity in US freestanding birth centers need documentation. METHODS: Pregnancies recorded in the American Association of Birth Centers Perinatal Data Registry were analyzed (n = 4,455) to form 2 groups of primiparous women (n = 964; 1:1 matching of women with normal body mass indices [BMIs] and women with obese BMIs [>30]), using propensity score matching to address the imbalance of potential confounders. Groups were compared on a range of outcomes. Differences between groups were evaluated using χ2 test for categorical variables and Student's t test for continuous variables. Paired t test and McNemar's test evaluated the differences among the matched pairs. RESULTS: The majority of women with obese BMIs experienced uncomplicated perinatal courses and vaginal births. There were no significant differences in antenatal complications, proportion of prolonged pregnancy, prolonged first and second stage labor, rupture of membranes longer than 24 hours, postpartum hemorrhage, or newborn outcomes between women with obese BMIs and normal BMIs. Among all women with intrapartum referrals or transfers (25.3%), the primary indications were prolonged first stage or second stage (55.4%), inadequate pain relief (14.8%), client choice or psychological issue (7.0%), and meconium (5.3%). Primiparous women with obesity who started labor at a birth center had a 30.7% transfer rate and an 11.1% cesarean birth rate. DISCUSSION: Women with obese BMIs without medical comorbidity can receive safe and effective midwifery care at freestanding birth centers while anticipating a low risk for cesarean birth. The risks of potential, obesity-related perinatal complications should be discussed with women when choosing place of birth; however, pregnancy complicated by obesity must be viewed holistically, not simply through the lens of obesity.

RESUMEN

OBJECTIVES: It is important to understand relationships of gestational weight gain with adverse pregnancy outcomes in women with chronic hypertension, given their high baseline risk of adverse outcomes. We assessed associations of gestational weight gain with adverse pregnancy outcomes in women with chronic hypertension by pre-pregnancy body mass index categories. STUDY DESIGN: We identified 14,369 women with chronic hypertension using electronic health records from 3 integrated health care delivery systems (2005-2014). Gestational weight gain-for-gestational age charts were used to calculate gestational weight gain z-scores, which account for gestational age. Modified Poisson regression models using generalized estimating equations were used to calculate relative risks and 95% confidence intervals, adjusted for sociodemographic and medical characteristics. MAIN OUTCOME MEASUREMENTS: Preeclampsia, preterm delivery, cesarean delivery, neonatal intensive care unit admission, birthweight (extracted from the electronic health record). RESULTS: In women with normal weight or overweight, low gestational weight gain (z-score < -1) was associated with 27-28% greater risk of preterm delivery and 48-82% greater risk of small-for-gestational age birthweight, while high gestational weight gain (z-score > 1) was associated with 40-90% greater risk of preeclampsia and 59-113% greater risk of large-for-gestational age birthweight. In women with obesity, low gestational weight gain was associated with 27-54% lower risk of several adverse pregnancy outcomes, including preeclampsia and cesarean delivery. CONCLUSIONS: In women with chronic hypertension and normal weight or overweight, moderate gestational weight gain may confer the lowest risk of adverse outcomes. In women with chronic hypertension and obesity, low gestational weight gain may be necessary for the lowest risk of adverse pregnancy outcomes.

RESUMEN

BACKGROUND: The aim of this study was to compare rates of induction and subsequent caesarean delivery among nulliparous women with private versus publicly funded health care at a single institution. This is a retrospective cohort study using the electronic booking and delivery records of nulliparous women with singleton pregnancies who delivered between 2010 and 2015 in an Irish Tertiary Maternity Hospital (approx. 9000 deliveries per annum). METHODS: Data were extracted from the National Maternity Hospital (NMH), Dublin, Patient Administration System (PAS) on all nulliparous women who delivered a liveborn infant at ≥37 weeks gestation during the 6-year period. At NMH, all women in spontaneous labour are managed according to a standardised intrapartum protocol. Twenty-two thousand two hundred thirty-two women met the inclusion criteria. Of these, 2520 (12.8%) were private patients; the remainder (19,712; 87.2%) were public. Mode of and gestational age at delivery, rates of and indications for induction of labour, rates of pre-labour caesarean section, and maternal and neonatal outcomes were examined. Rates of labour intervention and subsequent maternal and neonatal outcomes were compared between those with and without private health cover. RESULTS: Women attending privately were more than twice as likely to have a pre-labour caesarean section (12.7% vs. 6.5%, RR = 2.0, [CI 1.8-2.2])); this finding persisted following adjustment for differences in maternal age and body mass index (BMI) (adjusted relative risk 1.74, [CI 1.5-2.0]). Women with private cover were also more likely to have induction of labour and significantly less likely to labour spontaneously. Women who attended privately were significantly more likely to have an operative vaginal delivery, whether labour commenced spontaneously or was induced. CONCLUSIONS: These findings demonstrate significant differences in rates of obstetric intervention between those with private and public health cover. This division is unlikely to be explained by differences in clinical risk factors as no significant difference in outcomes following spontaneous onset of labour were noted. Further research is required to determine the roots of the disparity between private and public decision-making. This should focus on the relative contributions of both mothers and maternity care professionals in clinical decision making, and the potential implications of these choices.

RESUMEN

BACKGROUND: The decision to initiate pharmacotherapy is integral in the care for pregnant women with gestational diabetes mellitus (GDM). We sought to compare pregnancy outcomes between two threshold percentages of elevated glucose values prior to initiation of pharmacotherapy for GDM. We hypothesized that a lower threshold at pharmacotherapy initiation will be associated with lower rates of adverse perinatal outcomes. METHODS: This was a retrospective cohort study of women with GDM delivering in a single tertiary care center. Pregnancy outcomes were compared using bivariable and multivariable analyses between women who started pharmacotherapy (insulin or oral hypoglycemic agent) after a failed trial of dietary modifications at two different ranges of elevated capillary blood glucose (CBG) values: Group 1 when 20-39% CBG values were above goal; Group 2 when ≥40% CBG values were above goal. The primary outcome was a composite GDM-associated neonatal adverse outcome that included: macrosomia, large for gestational age (LGA), shoulder dystocia, hypoglycemia, hyperbilirubinemia requiring phototherapy, respiratory distress syndrome, stillbirth, and neonatal demise. Secondary outcomes included cesarean delivery, preterm birth (< 37 weeks), neonatal intensive care unit (NICU) admission, and small for gestational age (SGA). RESULTS: A total of 417 women were included in the study. In univariable analysis, the composite neonatal outcome was statistically significantly higher in Group 2 compared to Group 1 (47.9% vs. 31.4%, p = 0.001). In addition, rates of preterm birth (15.7% vs 7.4%, p = 0.011), NICU admission (11.7% vs 4.0%, p = 0.006), and LGA (21.2% vs 9.1% p = 0.001) were higher in Group 2. In contrast, higher rates of SGA were noted in Group 1 (8.0% vs. 2.9%, p = 0.019). There was no difference in cesarean section rates. These findings persisted in multivariable analysis after adjusting for confounding factors (composite neonatal outcome aOR = 0.50, 95%CI [0.31-0.78]). CONCLUSIONS: Initiation of pharmacotherapy for GDM when 20-39% of CBG values are above goal, compared to ≥40%, was associated with decreased rates of adverse neonatal outcomes attributable to GDM. This was accompanied by higher rates of SGA among women receiving pharmacotherapy at the lower threshold. Additional studies are required to identify the optimal threshold of abnormal CBG values to initiate pharmacotherapy for GDM.

RESUMEN

Hypertensive disorders of pregnancy account for approximately 22% of all maternal deaths in Latin America and the Caribbean. Pharmacotherapies play an important role in preventing and reducing the occurrence of adverse outcomes. However, the patterns of medications used for treating women with hypertensive disorders of pregnancy (HDP) living in this country is unclear. A population-based birth cohort study including 4262 women was conducted to describe the pattern of use of cardiovascular agents and acetylsalicylic acid between women with and without HDP in the 2015 Pelotas (Brazil) Birth Cohort. The prevalence of maternal and perinatal outcomes in this population was also assessed. HDP were classified according to Ministry of Health recommendations. Medications were defined using the Anatomical Therapeutic Chemical Classification System and the substance name. In this cohort, 1336 (31.3%) of women had HDP. Gestational hypertension was present in 636 (47.6%) women, 409 (30.6%) had chronic hypertension, 191 (14.3%) pre-eclampsia, and 89 (6.7%) pre-eclampsia superimposed on chronic hypertension. Approximately 70% of women with HDP reported not using any cardiovascular medications. Methyldopa in monotherapy was the most frequent treatment (16%), regardless of the type of HDP. Omega-3 was the medication most frequently reported by women without HDP. Preterm delivery, caesarean section, low birth weight, and neonatal intensive care admissions were more prevalent in women with HDP. Patterns of use of methyldopa were in-line with the Brazilian guidelines as the first-line therapy for HDP. However, the large number of women with HDP not using medications to manage HDP requires further investigation.

RESUMEN

BACKGROUND: Maternal perception of decreased fetal movements is commonly used to assess fetal well-being. However, there are different opinions on whether healthcare professionals should encourage maternal observation of fetal movements, as researchers claim that raising awareness increases unnecessary interventions, without improving perinatal health. We aimed to investigate whether cesarean sections and labor induction increase by raising women's awareness of fetal movements through Mindfetalness. Further, we aimed to study perinatal health after implementing Mindfetalness in maternity care. METHODS: In a cluster randomized controlled trial, 67 maternity clinics were allocated to Mindfetalness or routine care. In the Mindfetalness group, midwives distributed a leaflet telling the women to focus on the character, strength and frequency of the fetal movements without counting each movement. The instruction was to do so for 15 min daily when the fetus was awake, from gestational week 28 until birth. In this sub-group analysis, we targeted women born in Sweden giving birth from 32 weeks' gestation. We applied the intention-to-treat principle. RESULTS: The Mindfetalness group included 13,029 women and the Routine-care group 13,456 women. Women randomized to Mindfetalness had less cesarean sections (18.4% vs. 20.0%, RR 0.92, CI 0.87-0.97) and labor inductions (19.2% vs. 20.3%, RR 0.95, CI 0.90-0.99) compared to the women in the Routine-care group. Less babies were born small for gestational age (8.5% vs. 9.3%, RR 0.91, CI 0.85-0.99) in the Mindfetalness group. Women in the Mindfetalness group contacted healthcare due to decreased fetal movements to a higher extent than women in the Routine care group (7.8% vs. 4.3%, RR 1.79, CI 1.62-1.97). The differences remain after adjustment for potential confounders. CONCLUSIONS: Raising awareness about fetal movements through Mindfetalness decreased the rate of cesarean sections, labor inductions and small-for-gestational age babies.

RESUMEN

BACKGROUND: Vaginal birth after caesarean (VBAC) is a safe mode of birth for most women but internationally VBAC rates remain low. In Australia women planning a VBAC may experience different models of care including continuity of care (CoC). There are a limited number of studies exploring the impact and influence of CoC on women's experiences of planning a VBAC. Continuity of care (CoC) with a midwife has been found to increase spontaneous vaginal birth and decrease some interventions. Women planning a VBAC prefer and benefit from CoC with a known care provider. This study aimed to explore the influence, and impact, of continuity of care on women's experiences when planning a VBAC in Australia. METHODS: The Australian VBAC survey was designed and distributed via social media. Outcomes and experiences of women who had planned a VBAC in the past 5 years were compared by model of care. Standard fragmented maternity care was compared to continuity of care with a midwife or doctor. RESULTS: In total, 490 women completed the survey and respondents came from every State and Territory in Australia. Women who had CoC with a midwife were more likely to feel in control of their decision making and feel their health care provider positively supported their decision to have a VBAC. Women who had CoC with a midwife were more likely to have been active in labour, experience water immersion and have an upright birthing position. Women who received fragmented care experienced lower autonomy and lower respect compared to CoC. CONCLUSION: This study recruited a non-probability based, self-selected, sample of women using social media. Women found having a VBAC less traumatic than their previous caesarean and women planning a VBAC benefited from CoC models, particularly midwifery continuity of care. Women seeking VBAC are often excluded from these models as they are considered to have risk factors. There needs to be a focus on increasing shared belief and confidence in VBAC across professions and an expansion of midwifery led continuity of care models for women seeking a VBAC.

RESUMEN

OBJECTIVE: We aimed to evaluate the contents of the neonatal discharge summary (NDS), an important communication tool that should contain evidence-based information. METHODS: A quali-quantitative study of NDSs delivered from 29 hospitals of Lazio (Italy) in 2014 and 2017 was conducted. We used content analysis to assess the written information and logistic regression to estimate the association between outcomes (compliance with the International Code, health messages, and information on neonatal screenings) and some hospital's characteristics. RESULTS: NDSs conforming to International Code were associated with low rate of C-section (p < 0.05). Hospitals belonging to Local Health Authorities (p < 0.05) and with a lower prevalence of C-section (p < 0.05) had a greater attitude to promote infant health. The year of collection was associated with information on neonatal screenings (p < 0.05). CONCLUSIONS: An effort is required by hospitals to reduce their level of medicalization, in clinical practice and prescriptive attitudes, which affects the NDSs delivered to parents.

RESUMEN

OBJECTIVE: To evaluate the difference in odds of cesarean delivery in term, singleton, vertex pregnancies between the midwife and obstetrician-led services at the same rural tertiary care center. METHODS: A retrospective cohort study of term, singleton, and vertex deliveries in patients without a history of cesarean delivery was performed. Patients self-selected a delivery service. The primary outcome was the odds of cesarean delivery between midwife and obstetrician-led services. After propensity score matching, logistic regression was performed on the matched sample to assess the adjusted odds of cesarean delivery. RESULTS: From January 2015 to December 2017, 1,787 (80.2% of total) deliveries were analyzed with management of 956 (53.5%) by the midwife service and 831 (46.5%) by the obstetrician-led service. The rate of cesarean delivery was 20.7% (n=172) in the obstetrician-led service and 13.1% (n=125) in the midwife service. In the matched sample, the odds of cesarean delivery were lower in the midwife service compared with the obstetrician-led service in unadjusted and adjusted analyses (odds ratio [OR] 0.62, 95% CI 0.47-0.81; adjusted odds ratio [aOR] 0.58, 95% CI 0.44-0.80). Older maternal age (OR 1.02, 95% CI 1.00-1.06; aOR 1.07, 95% CI 1.04-1.10) and higher delivery body mass index (OR 1.06, 95% CI 1.04-1.08; aOR 1.07, 95% CI 1.04-1.09) were associated with higher odds of cesarean delivery. Increased parity was associated with decreased odds of cesarean delivery (OR 0.41, 95% CI 0.31-0.55; aOR 0.35, 95% CI 0.26-0.48). There were no differences in neonatal outcomes. CONCLUSION: At a single rural tertiary care center, patients on the midwife service have significantly lower adjusted odds of cesarean delivery than patients on the obstetrician-led service.
