Using Robson's Ten-Group Classification System for comparing caesarean section rates in Europe: an analysis of routine data from the Euro-Peristat study.

OBJECTIVE: Robson's Ten Group Classification System (TGCS) creates clinically relevant sub-groups for monitoring caesarean birth rates. This study assesses whether this classification can be derived from routine data in Europe and uses it to analyse national caesarean rates. DESIGN: Observational study using routine data. SETTING: Twenty-seven EU member states plus Iceland, Norway, Switzerland and the UK. POPULATION: All births at ≥22 weeks of gestational age in 2015. METHODS: National statistical offices and medical birth registers derived numbers of caesarean births in TGCS groups. MAIN OUTCOME MEASURES: Overall caesarean rate, prevalence and caesarean rates in each of the TGCS groups. RESULTS: Of 31 countries, 18 were able to provide data on the TGCS groups, with UK data available only from Northern Ireland. Caesarean birth rates ranged from 16.1 to 56.9%. Countries providing TGCS data had lower caesarean rates than countries without data (25.8% versus 32.9%, P = 0.04). Countries with higher caesarean rates tended to have higher rates in all TGCS groups. Substantial heterogeneity was observed, however, especially for groups 5 (previous caesarean section), 6, 7 (nulliparous/multiparous breech) and 10 (singleton cephalic preterm). The differences in percentages of abnormal lies, group 9, illustrate potential misclassification arising from unstandardised definitions. CONCLUSIONS: Although further validation of data quality is needed, using TGCS in Europe provides valuable comparator and baseline data for benchmarking and surveillance. Higher caesarean rates in countries unable to construct the TGCS suggest that effective routine information systems may be an indicator of a country's investment in implementing evidence-based caesarean policies. TWEETABLE ABSTRACT: Many European countries can provide Robson's Ten-Group Classification to improve caesarean rate comparisons.

Neurodevelopment at 2 years and umbilical artery Doppler in cases of very preterm birth after prenatal hypertensive disorder or suspected fetal growth restriction: EPIPAGE-2 prospective population-based cohort study.

OBJECTIVE: To investigate the association between absent or reversed end-diastolic flow (ARED) on umbilical artery Doppler ultrasound and poor neurological outcome at 2 years of age after very preterm birth associated with suspected fetal growth restriction (FGR) or maternal hypertensive disorders. METHODS: The study population comprised all very preterm (22-31 completed weeks) singleton pregnancies delivered because of suspected FGR and/or maternal hypertensive disorders that had umbilical artery Doppler and 2-year follow-up available included in EPIPAGE-2, a prospective, nationwide, population-based cohort of preterm births in France in 2011. Univariate and two-level multivariable logistic regression analyses were used to assess the association of ARED in the umbilical artery, as compared with normal or reduced end-diastolic flow, with severe or moderate neuromotor and/or sensory disability and with an Ages and Stages Questionnaire (ASQ) score below a threshold. This was defined as a score more than 2 SD below the mean in any of the five domains, at age 2, adjusting for gestational age at delivery. ASQ is used to identify children at risk of developmental delay requiring reinforced follow-up and further evaluation. Descriptive statistics and bivariate tests were weighted according to the duration of the inclusion periods. RESULTS: The analysis included 484 children followed up at 2 years of age, for whom prenatal umbilical artery Doppler ultrasound was available. Among them, 8/484 (1.6%) had severe or moderate neuromotor and/or sensory disability, and 156/342 (45.4%) had an ASQ score below the threshold. Compared with normal or reduced end-diastolic flow in the umbilical artery (n = 305), ARED (n = 179) was associated with severe or moderate neuromotor and/or sensory disability (adjusted odds ratio (OR), 11.3; 95% CI, 1.4-93.2) but not with an ASQ score below the threshold (adjusted OR, 1.2; 95% CI, 0.8-1.9). CONCLUSION: Among children delivered before 32 weeks of gestation due to suspected FGR and/or maternal hypertensive disorder who survived until 2 years of age, prenatal ARED in the umbilical artery was associated with a higher incidence of severe or moderate neuromotor and/or sensory disability.

Delivery room management of extremely preterm infants: the EPIPAGE-2 study.

OBJECTIVE: To analyse the delivery room management of babies born between 22 and 26 weeks of completed gestational age and to identify the factors associated with the withholding or withdrawal of intensive care. STUDY DESIGN: Population-based cohort study. PATIENTS AND METHODS: Our study population comprised 2145 births between 22 and 26 completed weeks enrolled in the EPIPAGE-2 study, a French cohort of very preterm infants born in 2011. The primary outcome measure was withholding or withdrawal of intensive care in the delivery room. RESULTS: Among infants born alive at 22-23 weeks, intensive care was withheld or withdrawn for >90%. At 24 weeks, resuscitative measures were withheld or withdrawn for 38%, at 25 weeks for 8% and at 26 weeks for 3%. Other factors besides gestational age at birth associated with this withholding or withdrawal for infants born at 24-26 weeks were birth weight <600 g, emergency delivery (within 24 h of the mother's admission) and singleton pregnancy. Although rates of withholding or withdrawal of intensive care varied substantially between maternity units (from 0% to 100%), the variability was primarily explained by differences in distributions of gestational age at birth. CONCLUSIONS: Although gestational age is only one factor predicting survival of preterm infants, practices in France appear to be based primarily on this factor, which thus has direct effects on the survival of extremely preterm infants. The ethical implications of basing life and death decisions only on gestational age before 25 weeks require further examination.

[Maternal factors influencing breastfeeding on a neonatal intensive care unit]. / Impacts des facteurs maternels sur l'allaitement maternel en réanimation néonatale.

OBJECTIVE: Admission at birth to a Neonatal Intensive Care Unit (NICU) complicates breastfeeding especially for preterm babies despite hospital staff trained to encourage breastfeeding. The aim of this study was to find factors related to the mother, the pregnancy or the neonate influencing breastfeeding rate on a NICU. PATIENTS AND METHODS: This was a retrospective study including neonatal admissions to the NICU at Antoine-Béclère University Hospital from 1st May 2009 to 30th April 2010. Data was collected from medical notes. The breastfeeding rate (at initiation and at discharge) was analysed with regards to maternal age, method of procreation, type of pregnancy (single or multiple), parity, mode of delivery (vaginal delivery or C-section), birthweight, gestational age and intra-uterine growth restriction (IUGR). RESULTS: The study was based on 460 neonates having complete documentation. The average maternal age was 32 years. Premature infants represented 74.8% of the population (median gestational age=34 weeks) of which 57% were less than 33 weeks (42.6% of all infants, n=196). The median birthweight was 1900 g with 17.6% of IUGR infants. Breastfeeding rate at initiation was 58.7 and 43.9% at discharge (mean admission days: 17.1 [0-180], median=8 days). For infants born of multiple pregnancies (24.3% of the population) 51.6% were born of medically assisted pregnancies (MAP) and 17.6% of spontaneous pregnancies. Breastfeeding rate among these infants was 57.1% at initiation and 45.5% at discharge. It was higher in infants born of MAP at initiation (70.3% versus 55.8% for spontaneous pregnancies, P<0.05) and at discharge (49.5% versus 42.5% for spontaneous pregnancies). For these infants, average maternal age was higher for breastfed infants (33.9 versus 32.1 years for the formula-fed, P<0.05). Breastfeeding rate in infants born to primipares was higher at initiation (64.9% versus 53.6% for multipares, P<0.05) and at discharge (48.5% versus 40.8% for multipares, P<0.05). The rate of infants breastfed was influenced neither by maternal age alone (31.8 ± 5.6 versus 31.4 ± 5.7 years for formula-fed), nor by type of delivery (56.7% for infants born by C-section versus 62.5% for infants born by vaginal delivery), nor gestational age (33.2 ± 4.3 weeks for breastfed, versus 33.4 ± 4.2 weeks for formula-fed infants), nor birthweight (2060 ± 978 g for breastfed versus 2055 ± 909 g for formula-fed infants), nor IUGR (58% versus 58.8% for eutrophes). DISCUSSION: Our maternal population was different as 16.7% of deliveries were accounted for by MAP, superior to the French average (<10%). We describe for the first time MAP as a positive influencing factor on breastfeeding rates in newborns admitted to a NICU. A better breastfeeding information policy during pregnancy, higher maternal age and increased multiple pregnancies would explain a higher breastfeeding rate among the women who had MAP. An impact of increasing maternal age was found on the rate of breastfed infants born of MAP. Primiparity was also a contributing factor for breastfeeding. Professional formation for all hospital staff concerned would be essential to give out clear and consistent information to families and to encourage support and intimacy throughout hospitalisation as well as at discharge.
