Perinatal and social factors predicting caesarean birth in a 2004 Australian birth cohort

Background

The proportion of babies born by caesarean section in Australia has almost doubled over the last 25 years. Factors known to contribute to caesarean such as higher maternal age, mothers being overweight or obese, or having had a previous caesarean do not completely account for the increased rate and it is clear that other influences exist.

Spontaneous vaginal birth following induction with intravenous oxytocin: Three oxytocic regimes to minimise blood loss post birth

BackgroundNo evidence was identified in relation to the downward titration/cessation of intravenous oxytocin post spontaneous vaginal birth, in the absence of postpartum haemorrhage (PPH); suggesting clinicians’ management is based on personal preference in the absence of evidence.AimTo determine the proportion of induced women with a spontaneous vaginal birth and PPH, when intravenous oxytocin was utilised intrapartum and ceased 15, 30 or 60 minutes post birth.MethodsThis three armed pilot randomised controlled trial, was undertaken on the Birth Suite of an Australian tertiary obstetric hospital. Incidence of PPH was assessed using univariable and adjusted logistic regression, which compared the effect of titrating intravenous oxytocin post birth on the likelihood of PPH, relative to the 15 minute titration group.FindingsPostpartum haemorrhage occurred in 26% (30 of 115), 20% (23 of 116), and 22% (30 of 134) of women randomised to a 15, 30 and 60 minute titration time post birth, with no statistically significant differences between groups.ConclusionThere was no difference in the incidence of PPH between the three groups. Therefore, we question the benefit of delaying cessation of intravenous oxytocin for 60 minutes post birth. Further investigation in this cohort is recommended, to compare the incidence of PPH when intravenous oxytocin is ceased either immediately, or 30 minutes post birth. This research is warranted, as an evidence-based framework is lacking, to guide midwives globally in relation to their management of intravenous oxytocin post an induced spontaneous vaginal birth, in the absence of PPH.

Background

Perinatal mortality remains a major international problem responsible for nearly six million stillbirths and neonatal deaths.

Risk factors for severe perineal trauma during vaginal childbirth: A Western Australian retrospective cohort study

AimTo determine rates and risk factors for third and fourth degree perineal tears (severe perineal trauma) in a Western Australian context.Design and settingA retrospective hospital-based cohort study was performed using computerised data for 10,408 singleton vaginal deliveries from 28 weeks gestation.MethodsWomen with severe perineal trauma were compared to those without. Logistic regression analysis, stratified by parity, was used to assess demographic and obstetric factors associated with perineal trauma.ResultsSevere perineal trauma incidence was 3% (338/10408), 5.4% (239/4405) for primiparas and 1.7% (99/5990) for multiparas (p < 0.001). Adjusted risk factors associated with trauma and common across parity included Asian or Indian ethnicity, shoulder dystocia and assisted delivery. Epidural analgesia (OR 0.72, 95% CI 0.54–0.96), preterm birth (OR 0.40, 95% CI 0.23–0.72) and episiotomy (OR 0.54, 95% CI 0.39–0.74) were protective in primiparas, while episiotomy was associated with increased risk in multiparas (OR 2.01, 95% CI 1.18–3.45). Additional factors among primiparas were occipito posterior (OP) delivery (OR 3.35, 95% CI 1.75–6.41) and prolonged second stage (OR 1.98, 95% CI 1.46–2.68), and among multiparas included gestational diabetes (OR 1.78, 95% CI 1.04–3.03) and birth weight >4000 g (OR 1.86, 95% CI 1.10–3.15).ConclusionParity differences in risk factors such as episiotomy, infant weight, OP delivery, gestational diabetes and prolonged second stage warrant investigation into clinical management. Although rates differ internationally, and replication evidence has confirmed consistency for certain demographic and obstetric factors, the development of internationally endorsed clinical guidelines and further research around interventions to protect the perineum are recommended.     

Oral,systemic and socioeconomic factors associated with preterm birth

Background

The rates of preterm births have been increasing worldwide. Complications related to preterm births are associated with increased costs of care, and have a direct impact on the health system of the countries. Therefore, it is important to address factors associated with preterm birth in order to provide prevention strategies.

Prevalence and risk factors for postnatal depression in Sabah,Malaysia: A cohort study

BackgroundPostnatal depression can have serious consequences for both the mother and infant. However, epidemiological data required to implement appropriate early prevention are still lacking in Malaysia.AimTo investigate the prevalence of postnatal depression within six months postpartum and associated risk factors among women in Sabah, Malaysia.MethodsA prospective cohort study of 2072 women was conducted in Sabah during 2009–2010. Participants were recruited at 36–38 weeks of gestation and followed up at 1, 3 and 6 months postpartum. The presence of depressive symptoms was assessed using the validated Malay version of the Edinburgh Postnatal Depression Scale. Logistic regression analyses were performed to ascertain risk factors associated with postnatal depression.FindingsOverall, 14.3% of mothers (95% confidence interval (CI) 12.5–16.2%) had experienced depression within the first six months postpartum. Women depressed during pregnancy (odds ratio (OR) 3.71, 95% CI 2.46–5.60) and those with consistent worries about the newborn (OR 1.68, 95% CI 1.16–2.42) were more likely to suffer from depression after childbirth. Women whose husband assisted with infant care (OR 0.43, 95% CI 0.20–0.97) and mothers who were satisfied with their marital relationship (OR 0.27, 95% CI 0.09–0.81) appeared to incur a reduced risk of postnatal depression.ConclusionA substantial proportion of mothers suffered from postnatal depression in Sabah, Malaysia. Screening and intervention programmes targeting vulnerable subgroups of women during antenatal and early postpartum periods are recommended to deal with the problem.     

The prevalence and incidence of HIV among injection drug users: A five year panel study

Six hundred and one injection drug users (IDUs) who attended drug treatment programs in Miami, Florida, were enrolled in a panel study to determine the prevalence and incidence of human immunodeficiency virus (HIV) and associated risk factors. A structured questionnaire which elicited injection and sexual behaviors was administered and blood was obtained by venipduncture. All participants were reassessed at six month intervals for 5 years. The baseline prevalence of HIV was 16.3%. African–Americans had a prevalence of HIV (37.1%) that was significantly higher than that of non-Hispanic whites (7.6%); the prevalence of HIV among Hispanics was 27.2%. Persons who were more than thirty years of age were more likely to test HIV positive (17.8%) than were younger participants (9.7%). The annual incidence per 1000 person-years of exposure for the 503 initially seronegative participants was consistently low for each year of the study. The 5 year incidence was 4.1 per 1000 person years; 7.5 for men and 1.7 for women, 7.5 for African–Americans and 3.8 for non-Hispanic whites. No Hispanic participants seroconverted. Multivariate logistic techniques were used to identify the independent risk factors for HIV prevalence. Earlier injection, ethnicity, and income were independently associated with HIV serostatus. A history of a sexually transmitted disease was marginally associated with HIV prevalence. Low incidence probably is a function of the reduction of risk behavior that occurred over the course of the study and the stage of the epidemic.     

Feasibility,acceptability and sustainability of postpartum contraceptive implant provision by midwives in NSW public hospitals

BackgroundRepeat pregnancy in the first year after a birth is common. Many of these conceptions are unintended and may be prevented by providing access to contraception in the immediate postpartum period. Midwives in the hospital setting could potentially play a greater role in improving postnatal contraception information and provision.AimWe sought to implement and examine the success of a program training hospital-based midwives in immediate postpartum implant insertion.MethodsThis mixed methods study in two hospitals in New South Wales sought to explore the feasibility, acceptability and sustainability of a program that provided competency-based implant insertion training for midwives. The study documented training completion, implant insertion numbers and experience, and conducted end of study interviews with midwives and stakeholders.FindingsTwenty-seven midwives undertook training and inserted 265 implants during the study period. Interviews with 13 midwives and 11 stakeholders concluded the program to be feasible and acceptable with midwives reporting high satisfaction from their involvement. All interviewees felt that midwives were well placed to insert implants, and reported that challenges around workload and opportunities for practice were generally manageable. It was recognised that sustainability of the program would require supportive policy and regular insertion opportunities.ConclusionsMidwives successfully upskilled in implant insertions and there was widespread support for the program with expectations it would be sustained. Provision of contraceptive information and implant insertion by midwives in the immediate postpartum period is likely to increase contraceptive choice and access for women and contribute to reducing rapid repeat pregnancies.     

Cessation of breastfeeding in association with oxytocin administration and type of birth. A prospective cohort study

Background

Some studies have suggested an association between synthetic oxytocin administration and type of birth with the initiation and consolidation of breastfeeding.

Contraception provision in the postpartum period: Knowledge,views and practices of midwives

BackgroundWomen are susceptible to unintended pregnancies in the first year after giving birth, particularly as consideration of contraception may be a low priority during this time. Discussing and providing contraception before women leave hospital after giving birth may prevent rapid repeat pregnancy and its associated risks. Midwives are well placed to assist with contraceptive decision-making and provision; however, this is not routinely undertaken by midwives in the Australian hospital setting and little is known regarding their views and experiences in relation to contraception.MethodsAn anonymous survey was conducted with midwives at two urban hospitals in New South Wales to better understand their contraceptive knowledge, views and practices regarding midwifery-led contraception provision in the postpartum period.FindingsThe survey was completed by 128 midwives. Most agreed that information about contraception provided in the postpartum period is valuable to women, although their knowledge about different methods was variable. The majority (88%) believed that midwives have a role in providing contraceptive information, and 79% reported currently providing contraceptive counselling. However, only 14% had received formal training in this area.ConclusionFindings demonstrate that most midwives provide some contraception information and believe this is an important part of a midwife’s role. Yet most have not undertaken formal training in contraception. Additional research is needed to explore the content and quality of midwives’ contraception discussions with women. Training midwives in contraceptive counselling would ensure women receive accurate information about available options. Upskilling midwives in contraception provision may increase postpartum uptake and reduce rapid repeat pregnancies.     

A retrospective comparison of water birth and conventional vaginal birth among women deemed to be low risk in a secondary level hospital in Australia

BackgroundWater birth involves the complete birth of the baby under warm water. There is a lack of consensus regarding the safety of water birth.AimThis study aimed to describe the maternal and neonatal outcomes associated with water birth among labouring women deemed at low risk for obstetric complications and compare these outcomes against women of similar risk who had a standard land birth.MethodA retrospective audit and comparison of women giving birth in water with a matched cohort who birthed on land at Bankstown hospital over a 10 year period (2000–2009).ResultsIn total 438 childbearing women were selected for this study (N = 219 in each arm). Primigravida women represented 42% of the study population. There was no significant difference in mean duration of both first and second stages of labour or postpartum blood loss between the two birth groups. There were no episiotomies performed in the water birth arm which was significantly different to the comparison group (N = 33, p < 0.001). There were more babies in the water birth group with an Apgar score of 7 or less at 1 min (compared to land births). However, at 5 min there was no difference in Apgar scores between the groups. Three of eight special care nursery admissions in the water birth group were related to feeding difficulties.ConclusionThis is the largest study on water birth in an Australian setting. Despite the limitations of a retrospective audit the findings make a contribution to the growing body of knowledge on water birth.     

Impact of COVID-19 on breastfeeding intention and behaviour among postpartum women in five countries

BackgroundStudies regarding the impact of COVID-19 on breastfeeding have mostly used single- country samples or a qualitative design.AimThe objective of this study was to examine breastfeeding intention during pregnancy and breastfeeding behaviour among postpartum women in five countries during the COVID-19 pandemic and the associated factors.MethodsAn online questionnaire survey was conducted in Thailand, the United Kingdom, South Korea, Taiwan, and Brazil from July through November 2021. The study participants included 3253 mothers within six months of birth.FindingsAbout 90% of participants intended to breastfeed during pregnancy and 85.7% reported breastfeeding in the past 24 h. More than half reported their breastfeeding duration being as planned or longer despite COVID-19. Multivariate logistic regression models showed that being multiparous, ever tested COVID-19 positive, and having positive breastfeeding beliefs were associated with increased odds for intention to breastfeed during pregnancy. Lower maternal educational level, being primiparous, ever tested COVID-19 positive, and experiencing food insecurity were associated with decreased odds for breastfeeding duration being as planned or longer. Vaginal birth, currently working or on maternity leave, breastfeeding beliefs, breastfeeding support from spouse/partner/friend/relative, online support groups, and in-person or telephone contact with healthcare professionals were associated with increased odds for breastfeeding duration being as planned or longer.ConclusionBreastfeeding intention and behaviour remained high during the COVID-19 pandemic. Online support groups and telephone contact with health professionals were effective during the pandemic.     

Midwifery continuity of care and vaginal birth after caesarean section: A randomised controlled trial

Problem and backgroundCaesarean section (CS) rates in Australia and many countries worldwide are high and increasing, with elective repeat caesarean section a significant contributor.AimTo determine whether midwifery continuity of care for women with a previous CS increases the proportion of women who plan to attempt a vaginal birth in their current pregnancy.MethodsA randomised controlled design was undertaken. Women who met the inclusion criteria were randomised to one of two groups; the Community Midwifery Program (CMP) (continuity across the full spectrum — antenatal, intrapartum and postpartum) (n = 110) and the Midwifery Antenatal Care (MAC) Program (antenatal continuity of care) (n = 111) using a remote randomisation service. Analysis was undertaken on an intention to treat basis. The primary outcome measure was the rate of attempted vaginal birth after caesarean section and secondary outcomes included composite measures of maternal and neonatal wellbeing.FindingsThe model of care did not significantly impact planned vaginal birth at 36 weeks (CMP 66.7% vs MAC 57.3%) or success rate (CMP 27.8% vs MAC 32.7%). The rate of maternal and neonatal complications was similar between the groups.ConclusionModel of care did not significantly impact the proportion of women attempting VBAC in this study. The similarity in the number of midwives seen antenatally and during labour and birth suggests that these models of care had more similarities than differences and that the model of continuity could be described as informational continuity. Future research should focus on the impact of relationship based continuity of care.     

Relationship between the degree of perineal trauma at vaginal birth and change in haemoglobin concentration

Background

Postpartum anaemia is a problem with high prevalence that significantly affects maternal recovery. Among the causal factors is perineal trauma. However, it is still not known what degree of perineal trauma produces a greater reduction of haemoglobin.

A critical analysis of Australian policies and guidelines for water immersion during labour and birth

Background

Accessibility of water immersion for labour and/or birth is often dependent on the care provider and also the policies/guidelines that underpin practice. With little high quality research about the safety and practicality of water immersion, particularly for birth, policies/guidelines informing the practice may lack the evidence necessary to ensure practitioner confidence surrounding the option thereby limiting accessibility and women’s autonomy.
