Objective: To develop and validate a clinical prediction model for outcomes at 5 years of age for children born extremely preterm and receiving active perinatal management. Design: The EPIPAGE‐2 national prospective cohort. Setting: France, 2011. Population: Live‐born neonates between 24+0 and 26+6 weeks of gestation who received active perinatal management (i.e. birth in a tertiary‐level hospital, with antenatal steroids and resuscitation at birth). Methods: A prediction model using logistic modelling, including gestational age, small‐for gestational‐age (SGA) status and sex, was developed. Model performance was assessed through calibration and discrimination, with bootstrap internal validation. Main outcome measures: Survival without moderate or severe neurodevelopmental disability (NDD) at 5 years. Results: Among the 557 neonates included, 401 (72%) survived to 5 years, of which 59% survived without NDD (95% CI 54% to 63%). Predicted rates of survival without NDD ranged from 45% (95% CI 33% to 57%), to 56% (95% CI 49% to 64%) to 64% (95% CI 57% to 70%) for neonates born at 24, 25 and 26 weeks of gestation, respectively. Predicted rates of survival without NDD were 47% (95% CI 18% to 76%) and 62% (95% CI 49% to 76%) for SGA and non‐SGA children, respectively. The model showed good calibration (calibration slope 0.85, 95% CI 0.54 to 1.16; calibration‐in‐the‐large −0.0123, 95% CI −0.25 to 0.23) and modest discrimination (C‐index 0.59, 95% CI 0.53 to 0.65). Conclusions: A simple prediction model using three factors easily known antenatally may help doctors and families in their decision‐making for extremely preterm neonates receiving active perinatal management.

Aim: To describe the circumstances, causes and timing of death in extremely preterm infants. Methods: We included from the EPIPAGE‐2 study infants born at 24–26 weeks in 2011 admitted to neonatal intensive care units (NICU). Vital status and circumstances of death were used to define three groups of infants: alive at discharge, death with or without withholding or withdrawing life‐sustaining treatment (WWLST). The main cause of death was classified as respiratory disease, necrotizing enterocolitis, infection, central nervous system (CNS) injury, other or unknown. Results: Among 768 infants admitted to NICU, 224 died among which 89 died without WWLST and 135 with WWLST. The main causes of death were respiratory disease (38%), CNS injury (30%) and infection (12%). Among the infants who died with WWLST, CNS injury was the main cause of death (47%), whereas respiratory disease (56%) and infection (20%) were the main causes in case of death without WWLST. Half (51%) of all deaths occurred within the first 7 days of life, and 35% occurred within 8 and 28 days. Conclusion: The death of extremely preterm infants in NICU is a complex phenomenon in which the circumstances and causes of death are intertwined. [ABSTRACT FROM AUTHOR]

Objective: Our main objective was to examine if parental prenatal preferences predict delivery-room management of extremely preterm periviable infants. The secondary objectives were to describe parental involvement and the content of prenatal counseling given to parents for this prenatal decision. Design: Prospective study of neonates liveborn between 22 and 26 weeks of gestation in France in 2011 among the neonates included in the EPIPAGE-2 study Setting: 18 centers participating in the “Extreme Prematurity Group” substudy of the EPIPAGE-2 study. Patients: 302 neonates liveborn between 22–26 weeks among which 113 with known parental preferences while parental preferences were unknown or unavailable for 186 and delivery room management was missing for 3. Results: Data on prenatal counseling and parental preferences were collected by a questionnaire completed by professionals who cared for the baby at birth; delivery room (DR) management, classified as stabilization or initiation of resuscitation (SIR) vs comfort care (CC). The 113 neonates studied had a mean (SD) gestational age of 24 (0.1) weeks. Parents of neonates in the CC group preferred SIR less frequently than those with neonates in the SIR group (16% vs 88%, p < .001). After multivariate analysis, preference for SIR was an independent factor associated with this management. Professionals qualified decisions as shared (81%), exclusively medical (16%) or parental (3%). Information was described as medical with no personal opinion (71%), complete (75%) and generally pessimistic (54%). Conclusion: Parental involvement in prenatal decision-making did not reach satisfying rates in the studied setting. When available, prenatal parental preference was a determining factor for DR management of extremely preterm neonates. Potential biases in the content of prenatal counselling given to parents need to be evaluated. [ABSTRACT FROM AUTHOR]

Objective: To assess whether planned route of delivery is associated with perinatal and 2-year outcomes for preterm breech singletons.Design: Prospective nationwide population-based EPIPAGE-2 cohort study.Setting: France, 2011.Sample: Three hundred and ninety women with breech singletons born at 26-34 weeks of gestation after preterm labour or preterm prelabour rupture of membranes.Methods: Propensity-score analysis.Main Outcome Measures: Survival at discharge, survival at discharge without severe morbidity, and survival at 2 years of corrected age without neurosensory impairment.Results: Vaginal and caesarean deliveries were planned in 143 and 247 women, respectively. Neonates with planned vaginal delivery and planned caesarean delivery did not differ in survival (93.0 versus 95.7%, P = 0.14), survival at discharge without severe morbidity (90.4 versus 89.9%, P = 0.85), or survival at 2 years without neurosensory impairment (86.6 versus 91.6%, P = 0.11). After applying propensity scores and assigning inverse probability of treatment weighting, as compared with planned vaginal delivery, planned caesarean delivery was not associated with improved survival (odds ratio, OR 1.31; 95% confidence interval, 95% CI 0.67-2.59), survival without severe morbidity (OR 0.75, 95% CI 0.45-1.27), or survival at 2 years without neurosensory impairment (OR 1.04, 95% CI 0.60-1.80). Results were similar after matching on propensity score.Conclusions: No association between planned caesarean delivery and improved outcomes for preterm breech singletons born at 26-34 weeks of gestation after preterm labour or preterm prelabour rupture of membranes was found. The route of delivery should be discussed with women, balancing neonatal outcomes with the higher risks of maternal morbidity associated with caesarean section performed at low gestational age.

Survival rates of infants born before 25 weeks of gestation are low in France and have not improved over the past decade. Active perinatal care increases these infants' likelihood of survival.Objective: Our aim was to identify factors associated with active antenatal care, which is the first step of proactive perinatal care in extremely preterm births.Methods: The population included 1020 singleton births between 220/6 and 260/6 weeks of gestation enrolled in the Etude Epidémiologique sur les Petits Ages Gestationnels 2 study, a French national population-based cohort of very preterm infants born in 2011. The main outcome was 'active antenatal care' defined as the administration of either corticosteroids or magnesium sulfate or delivery by caesarean section for fetal rescue. A multivariable analysis was performed using a two-level multilevel model taking into account the maternity unit of delivery to estimate the adjusted ORs (aORs) of receiving active antenatal care associated with maternal, obstetric and place of birth characteristics.Results: Among the population of extremely preterm births, 42% received active antenatal care. After standardisation for gestational age, regional rates of active antenatal care varied between 22% (95% CI 5% to 38%) and 61% (95% CI 44% to 78%). Despite adjustment for individual and organisational characteristics, active antenatal care varied significantly between maternity units (p=0.03). Rates of active antenatal care increased with gestational age with an aOR of 6.46 (95% CI 3.40 to 12.27) and 10.09 (95% CI 5.26 to 19.36) for infants born at 25 and 26 weeks' gestation compared with those born at 24 weeks. No other individual characteristic was associated with active antenatal care.Conclusion: Even after standardisation for gestational age, active antenatal care in France for extremely preterm births varies widely with place of birth. The dependence of life and death decisions on place of birth raises serious ethical questions. [ABSTRACT FROM AUTHOR]

Background: Clinical guidelines do not recommend maintenance tocolysis for the management of preterm labour. The French national survey EVAPRIMA revealed it was administered to more than 50% of women hospitalised for preterm labour. Our aim was to identify the individual and organisational determinants associated with maintenance tocolysis. Methods: The study was a secondary analysis of the prospective population-based EVAPRIMA study database. Population study included every women hospitalised for preterm labour and at risk of receiving maintenance tocolysis, over a one month period, in 99 randomly selected French maternity units. Main outcome was the prescription of maintenance tocolysis. The association between maintenance tocolysis and individual (maternal or obstetrical) and organisational determinants were evaluated with multilevel analysis. Results: Of the 531 women included, 68.9% (95% CI 0.65-0.73) received maintenance tocolysis. The only individual factor associated with maintenance tocolysis was gestational age at admission; the rate of maintenance tocolysis was higher among women hospitalised before 32 weeks of gestation. The significantly different rates between maternity units demonstrated the existence of a maternity unit effect. Maintenance tocolysis was also associated with organisational determinants and was more frequent in level 1 (ORa = 6.54[2.21-19.40]) and level 2 maternity units (ORa = 3.68[1.28-10.59]), in units with less than 1500 deliveries/year (ORa = 5.27[4.43-19.44]), and in specific areas of France. Conclusion: A maternity unit effect, explained partly by the organisational characteristics of the units, plays a major role in the practice of maintenance tocolysis. Widespread dissemination of these results might improve adherence to clinical guidelines. [ABSTRACT FROM AUTHOR]

Background: Emerging evidence suggests intensity of perinatal care influences survival for extremely preterm babies. We evaluated the effect of differences in perinatal care intensity between centres on sensorimotor morbidity at 2 years of age. We hypothesised that hospitals with a higher intensity of perinatal care would have improved survival without increased disability.Methods: Foetuses alive at maternal admission to a level 3 hospital in France in 2011, subsequently delivered between 22 and 26 weeks gestational age (GA) and included in the EPIPAGE-2 national prospective observational cohort study formed the baseline population. Level of intensity of perinatal care was assigned according to hospital of birth, categorised into three groups using 'perinatal intensity' ratios (ratio of 24-25 weeks GA babies admitted to neonatal intensive care to foetuses of the same GA alive at maternal admission to hospital). Multiple imputation was used to account for missing data; hierarchical logistic regression accounting for births nested within centres was then performed.Results: One thousand one hundred twelve foetuses were included; 473 survived to 2 years of age (126 of 358 in low-intensity, 140 of 380 in medium-intensity and 207 of 374 in high-intensity hospitals). There were no differences in disability (adjusted odds ratios 0.93 (95% CI 0.28 to 3.04) and 1.04 (95% CI 0.34 to 3.14) in medium- and high- compared to low-intensity hospitals, respectively). Compared to low-intensity hospitals, survival without sensorimotor disability was increased in the population of foetuses alive at maternal admission to hospital and in live-born babies, but there were no differences when considering only babies admitted to NICU or survivors.Conclusions: No difference in sensorimotor outcome for survivors of extremely preterm birth at 2 years of age was found according to the intensity of perinatal care provision. Active management of periviable births was associated with increased survival without sensorimotor disability. [ABSTRACT FROM AUTHOR]
