Pregnant women at increased risk of adverse perinatal outcomes: A combination of less healthy behaviors and adverse psychosocial and socio-economic circumstances.

Smoking during pregnancy is associated with a multitude of health behaviors and with the psychosocial and socio-economic circumstances of pregnant women. Limited research has so far been conducted on the clustering of these characteristics and on their effect on pregnancy outcomes. This study aimed to identify different groups of pregnant women based on their behavioral, psychosocial and socio-economic characteristics and their pregnancy outcomes. In total, 2455 women who were 12 weeks pregnant completed a questionnaire on smoking behavior, health behaviors and psychosocial and socio-economic characteristics. Neonatal and maternal outcomes were extracted from the Dutch perinatal registration. Subgroups were identified with latent class analysis and adverse pregnancy outcomes were compared between subgroups with logistic regression. Women were classified into four latent classes. Two classes represented the healthy higher-educated pregnant women who did not smoke: one group of multigravida women and one of primigravida women, also characterized by less pregnancy-specific knowledge and more pregnancy-related stress. The remaining women were grouped into two less healthy groups. One group frequently quit smoking, reported less healthy eating, less physical activity and comparable stress levels as the healthy higher-educated groups. The last group contained the most smokers, had the highest scores on psychosocial and pregnancy-related stress and the most adverse socio-economic circumstances. This group had an increased risk of adverse maternal outcomes, in particular developing diabetes during pregnancy. A comprehensive and integrated approach is needed to improve outcomes in pregnancies with a combination of adverse health, psychosocial, and socio-economic conditions.

Patients' and professionals' barriers and facilitators to external cephalic version for breech presentation at term, a qualitative analysis in the Netherlands.

OBJECTIVE: external cephalic version (ECV) is a relatively simple and safe manoeuvre and a proven effective approach in the reduction of breech presentation at term. There is professional consensus that ECV should be offered to all women with a fetus in breech presentation, but only up to 70% of women eligible for ECV undergo an ECV attempt. The aim of the study was to identify barriers and facilitators for ECV among professionals and women with a breech presentation at term. DESIGN: qualitative study with semi-structured interviews. SETTING: Dutch hospitals. PARTICIPANTS: pregnant women with a breech presentation who had decided on ECV, and midwives and gynaecologists treating women with a breech presentation. MEASUREMENTS: on the basis of national guidelines and expert opinions, we developed topic lists to guide the interviews and discuss barriers and facilitators in order to decide on ECV (pregnant women) or advice on ECV (midwives and gynaecologists). FINDINGS: among pregnant women the main barriers were fear, the preference to have a planned caesarean section (CS), incomplete information and having witnessed birth complications within the family or among friends. The main facilitators were the wish for a home birth, the wish for a vaginal delivery and confidence of the safety of ECV. Among professionals the main barriers were a lack of knowledge to fully inform and counsel patients on ECV, and the inability to counsel women who preferred a primary CS. The main facilitator was an unambiguous policy on (counselling for) ECV within the region. CONCLUSION: we identified several barriers and facilitators possibly explaining the suboptimal implementation of ECV for breech presentation in the Netherlands. This knowledge should be taken into account in designing implementation strategies for ECV to improve the uptake of ECV by professionals and patients.

A trend analysis in referrals during pregnancy and labour in Dutch midwifery care 1988-2004.

OBJECTIVE: To assess the trends and patterns of referral from midwives to obstetricians within the Dutch maternity care system from 1988 to 2004, and the differences in referral patterns between nulliparous and parous women. DESIGN: A descriptive study. SETTING: The Dutch midwifery database (LVR1), which monitored 74% (1988) to 94% (2004) of all midwifery care in the Netherlands between 1988 and 2004. POPULATION: A total of 1 977 006 pregnancies, attended by a primary care level midwife. METHODS: The indications for referral from midwifery to obstetric care were classified into fifteen groups (eight antepartum, six intrapartum and one postpartum). The trends in referrals of these indications were analysed by general linear models. MAIN OUTCOME MEASURES: Trends in the percentage of antepartum, intrapartum and postpartum referrals from midwifery care to obstetric care; trends in the specific indications for referral; contribution of different groups of the indications to the trend. RESULTS: From 1988 to 2004 an increase of 14.5% (from 36.9 to 51.4%) occurred in referrals from primary midwifery care to secondary obstetric care either during pregnancy, childbirth or in the postpartum period. The timing of the referrals was as follows: antepartum +9.0%, intrapartum +5.2% and postpartum +0.3%. In parous women, the increase in referrals was greater (+16.6%) than in nulliparous women (+12.3%) (P = 0.001). The commonest indications for referrals in nulliparous women were anticipated or evident complications due to 'failure to progress in the first or second stage' and 'fetal distress'. Parous women were most commonly referred for anticipated or evident complications due to 'medical history' and 'fetal distress'. In nulliparous women, 52% of the increase in referrals was related to the need of pain relief and occurrence of meconium-stained amniotic fluid; in parous women, 54% of the increase in referrals was related to the general medical and obstetrical history of the women, particularly previous caesarean section, and the occurrence of meconium-stained amniotic fluid. CONCLUSIONS: During a 17-year period, there was a continuous increase in the referral rate from midwives to obstetricians. Previous caesarean section, requirement for pain relief and the presence of meconium-stained amniotic fluid were the main contributors to the changes in referral rates. Primary prevention of caesarean section and antenatal preparation for childbirth are important interventions in the maintenance of primary obstetric care for low-risk pregnant women.

Cost-effectiveness of different treatment strategies with intrapartum antibiotic prophylaxis to prevent early-onset group B streptococcal disease.

OBJECTIVE: To estimate the costs and effects of different treatment strategies with intrapartum antibiotic prophylaxis to prevent early-onset group B streptococcal (GBS) disease in the Netherlands. The treatment strategies include a risk-based strategy, a screening-based strategy, a combined screening/risk-based strategy and the current Dutch guideline. DESIGN: Cost-effectiveness analysis based on decision model. SETTING: Obstetric care system in the Netherlands. POPULATION/SAMPLE: Hypothetical cohort of 200,000 neonates. METHODS: A decision analysis model was used to compare the costs and effects of different treatment strategies with no treatment. Baseline estimates were derived from literature and a survey among parents of children affected by GBS disease. The analysis was performed from a societal perspective, and costs and effects were discounted at a percentage of 3%. Main outcome measures Cost per quality adjusted of life-year (QALY). RESULT: The risk-based strategy will prevent 352 cases of early-onset GBS for 5.0 million Euros, indicating a cost-effectiveness ratio of 7600 Euros per QALY gained. The combined screening risk-based strategy has comparable results. The current Dutch guideline resulted in lower effects for higher costs. The screening-based strategy shows the highest reduction in cases of early-onset GBS, however, at a cost-effectiveness ratio of 59,300 Euros per QALY gained. Introducing the polymerase chain reaction (PCR) test may lead to a more favourable cost-effectiveness ratio. CONCLUSION: In the Dutch system, the combined screening/risk-based strategy and the risk-based strategy have reasonable cost-effectiveness ratios. If it becomes feasible to add the PCR test, the cost-effectiveness of the combined screening/risk-based strategy may even be more favourable.
