Advantages and limitations of using national administrative data on obstetric blood transfusions to estimate the frequency of obstetric hemorrhages

International audience; BACKGROUND: Obstetric hemorrhages are a frequent cause of maternal death all over the world, but are not routinely monitored. Health systems administrative databases could be used for this purpose, but data quality needs to be assessed. OBJECTIVES: Using blood transfusion data recorded in administrative databases to estimate the frequency of obstetric hemorrhages. Research design A population-based study. Subjects Validation sub-sample: all mothers who gave birth in a French region in 2006-07 (35 123 pregnancies). Main study: all mothers who gave birth in France in 2006-07 (1 629 537 pregnancies). METHOD: Linkage and comparison of administrative data on blood transfu…

Total plasma protein in very preterm babies: prognostic value and comparison with illness severity scores

International audience; OBJECTIVE: We aimed to investigate the predictive value for severe adverse outcome of plasma protein measurements on day one of life in very preterm infants and to compare total plasma protein levels with the validated illness severity scores CRIB, CRIB-II, SNAP-II and SNAPPE-II, regarding their predictive ability for severe adverse outcome. METHODS: We analyzed a cohort of infants born at 24-31 weeks gestation, admitted to the tertiary intensive care unit of a university hospital over 10.5 years. The outcome measure was "severe adverse outcome" defined as death before discharge or severe neurological injury on cranial ultrasound. The adjusted odd ratio (aOR) and 95%…

Similarly increased congenital anomaly rates after intrauterine insemination and IVF technologies: a retrospective cohort study

International audience; BACKGROUND: While intrauterine insemination (IUI), a simple, inexpensive and non-invasive technique, is the most used assisted reproduction technology (ART) worldwide, the risk of major birth defects following IUI is paradoxically not well documented. METHODS: Retrospective cohort study performed in Burgundy, France, over a 9-year period which consisted of the cross analysis of two prospective databases, the Burgundy perinatal network database and the database of the assisted conception units in Burgundy. A total of 1348 ART singletons [in vitro fertilization technologies (IVFT): n= 903; IUI: n= 445] matched with 4044 infants conceived naturally, 552 ART twins (IVFT:…

Paediatric intensive care admissions for respiratory syncytial virus bronchiolitis in France: results of a retrospective survey and evaluation of the validity of a medical information system programme

SUMMARYThe purpose of this study was to describe the characteristics of patients with bronchiolitis admitted to a paediatric intensive care unit (PICU), and to evaluate a national registry of hospitalizations (Programme de Médicalisation des Systèmes d'Information; PMSI) as a potential source of epidemiological data. Of the 49 French PICUs invited to take part in a retrospective survey of children aged <2 years who were hospitalized during the 2005–2006 epidemic season, 24 agreed to participate. Overall, 467 children were enrolled: 75% were aged <2 months, 76% had positive respiratory syncytial virus (RSV) tests, 34·9% required non-invasive ventilation, 36·6% were mechanically ventila…

Hypoproteinemia on the first day of life and adverse outcome in very preterm infants admitted to the neonatal intensive care unit

International audience; OBJECTIVE: We aimed to investigate the relationship between day-1 hypoproteinemia and severe adverse outcome (SAO) in very preterm infants admitted to the neonatal intensive care unit (NICU). STUDY DESIGN: Retrospective study of all patients born from 24 to 31 weeks gestation and cared for in our NICU over an 8-year period. Infants were excluded if the serum protein value on the first day of life was not available. RESULT: A total of 913 patients were included. In all, 14.6% presented with SAO (death or severe neurological injury on cranial ultrasound). Hypoproteinemia (total protein level \textless40 g l(-1)) on day 1 of life occurred in 19.5 % of all patients. The …

Routine Probiotic Use in Very Preterm Infants: Retrospective Comparison of Two Cohorts

International audience; OBJECTIVE: Evidence supports the efficacy of probiotics in reducing necrotizing enterocolitis (NEC) in very low-birth-weight infants, although concerns remain with regard to their routine use. Since 2008 in our neonatal intensive care unit, a low dose of probiotics (unique strain) is administered as standard of care in all preterm babies born at 24 to 31 weeks' gestation. This study reports outcomes in infants receiving probiotic cohort (PC) compared with the historical cohort. DESIGN: Treatment with Lactobacillus rhamnosus Lcr35 (Lcr Restituo) (2 × 108 colony-forming units/12 h) was started early after birth and intention to treat was up to 36 weeks' gestation. The …

Economic analysis of the costs associated with prematurity from a literature review

International audience; Abstract : Objectives : To analyse published cost-of-illness studies that had assessed the cost of prematurity according to gestational age at birth. Methods : A review of the literature was carried out in March 2011 using the following databases: Medline, ScienceDirect, The Cochrane Library, Econlit and Business Source Premier, and a French Public-Health database. Key-word sequences related to ‘prematurity’ and ‘costs’ were considered. Studies that assessed costs according to the gestational age (GA) at the premature birth (<37 weeks of gestation) in industrialized countries and during the last two decades were included. Variations in the reported costs were anal…

Using Discharge Abstracts to Evaluate a Regional Perinatal Network: Assessment of the Linkage Procedure of Anonymous Data

To assess the Burgundy perinatal network (18 obstetrical units; 18 500 births per year), discharge abstracts and additional data were collected for all mothers and newborns. In accordance with French law, data were rendered anonymous before statistical analysis, and were linked to patients using a specific procedure. This procedure allowed data concerning each mother to be linked to those for her newborn(s). This study showed that all mothers and newborns were included in the regional database; the data for all mothers were linked to those for their infant(s) in all cases. Additional data (gestational age) were obtained for 99.9% of newborns.

Very preterm birth: who has access to antenatal corticosteroid therapy?

International audience; We describe the administration of antenatal corticosteroid therapy (ACT) for liveborn very preterm neonates in a population-based study. A total of 790 very preterm neonates (between 24 and 31 full weeks of gestation) were included in this regionally defined population of very preterm neonates in France. The main outcome measure was non-access to ACT. Data were analysed using logistic and polytomous models to control for neonatal and sociodemographic characteristics, mechanisms of very preterm birth and neonatal network organisation. As compared with level III, births in levels I-II maternity units were closely related to non-access to ACT (60.1% vs. 8.8%), but not t…

Les écarts entre la durée moyenne de séjour (DMS) observée au CHU de Dijon pour les hospitalisations des enfants de moins de 1000g sont-ils le fait d’une prise en charge trop longue ou d’une hétérogénéité des Groupes homogènes de malades (GHM) ?

Comparison of the ability of alternative birthweight and fetal weight standards to identify preterm newborns at increased risk of perinatal death

Objective To compare prediction of perinatal deaths among preterm infants based on fetal weight standards versus a new subpopulation-based birthweight standard. Design Population-based cohort study. Setting France. Population A total of 9100 preterm singletons, born between 24 and 36 weeks of gestation in 2000–09, in Burgundy (France). Methods We first classified all newborns as either small for gestational age (SGA) or not, based on alternative fetal weight or birthweight standards, including a new birthweight standard that excludes infants born to mothers with disease related to the weight of a fetus. Based on discrepancies between the different classifications, we then divided the newbor…
