Abstract [en]

AimThe aim of this study was to investigate differences in mortality up to 1year of age in extremely preterm infants (before 27weeks) born in seven Swedish healthcare regions. MethodsNational prospective observational study of consecutively born, extremely preterm infants in Sweden 2004-2007. Mortality was compared between regions. Crude and adjusted odds ratios and 95% CI were calculated. ResultsAmong 844 foetuses alive at mothers admission for delivery, regional differences were identified in perinatal mortality for the total group (22-26weeks) and in the stillbirth and perinatal and 365-day mortality rates for the subgroup born at 22-24weeks. Among 707 infants born alive, regional differences were found both in mortality before 12h and in the 365-day mortality rate for the subgroup (22-24weeks) and for the total group (22-26weeks). The mortality rates were consistently lower in two healthcare regions. There were no differences in the 365-day mortality rate for infants alive at 12h or for infants born at 25weeks. Neonatal morbidity rates among survivors were not higher in regions with better survival rates. Perinatal practices varied between regions. ConclusionMortality rates in extremely preterm infants varied considerably between Swedish healthcare regions in the first year after birth, particularly between the most immature infants.
