Low mortality and short-term morbidity in very preterm infants in Austria 2011-2016.

AIM: The current study determined survival, short-term neonatal morbidity and predictors for death or adverse outcome of very preterm infants in Austria. METHODS: This population-based cohort study included 5197 very preterm infants (53.3% boys) born between 2011 and 2016 recruited from the Austrian Preterm Outcome Registry. Main outcome measures were gestational age-related mortality and major short-term morbidities. RESULTS: Overall, survival rate of all live-born infants included was 91.6% and ranged from 47.1% and 73.4% among those born at 23 and 24 weeks of gestation to 84.9% and 88.2% among infants born at 25 and 26 weeks to more than 90.0% among those with a gestational age of 27 weeks or more. The overall prevalence of chronic lung disease, necrotising enterocolitis requiring surgery, intraventricular haemorrhage Grades 3-4, and retinopathy of prematurity Grades 3-5 was 10.0%, 2.1%, 5.5%, and 3.6%, respectively. Low gestational age, low birth weight, missing or incomplete course of antenatal steroids, male sex, and multiple births were significant risk predictors for death or adverse short-term outcome. CONCLUSION: In this national cohort study, overall survival rates were high and short-term morbidity rate was low.

Short-term morbidities in moderate and late preterm infants.

OBJECTIVE: To determine (1) the association between neonatal morbidity and gestational age and (2) the impact of pre-existing maternal medical conditions, pregnancy and birth complications on neonatal outcome in moderate and late preterm infants (32-36 completed weeks). METHODS: Retrospective single-centre cohort study including all moderate and late preterm infants without congenital anomalies born at the Children's and Maternity Hospital Linz, Austria, between January 2007 and June 2010. Stepwise regression analysis was used to determine significant associations between morbidities, maternal and perinatal complications and the gestational age. RESULTS: Of 870 infants included the incidence of neonatal morbidities increased from 24% at 36 weeks to 43% at 35 weeks', 55% at 34 weeks', 75% at 33 weeks' and 93% at 32 weeks' gestation. Infants at 32 weeks had a 4-fold (RR: 3.88; 95% CI: 1.87-8.06) increased risk compared with those at 36 weeks, and infants of 32 weeks were 16 times (RR: 16.01; 95% CI: 9.82-26.09) more likely to be admitted to the NICU than infants of 36 weeks'. Hyperbilirubinemia (29%) and respiratory morbidity (14.3%) were the most common neonatal diagnoses. Intrauterine growth restriction, preeclampsia, preterm premature rupture of the membranes, lack of antenatal steroid administration, antepartum hemorrhage, multiple pregnancy and male gender were all associated with any kind of neonatal morbidity, admission rate to the NICU and length of hospital stay (p<0.05). CONCLUSION: Nearly half of all infants suffered from any morbidity, and several risk factors were identified being significantly associated with NICU admission rate and length of hospitalization.

[Medical prescriptions to premature and newborn infants in an Austrian neonatal intensive care unit]. / Verschreibepraxis von Arzneimitteln bei Früh- und Neugeborenen auf einer österreichischen neonatologischen Intensivstation.

BACKGROUND: In December 2006, the European Commission issued the Regulation 1901/2006 with the aim to improve the development of medicines for children, because currently many of the pediatric drugs are used outside their authorization. The aim of the present study was to establish a status quo of the medical prescriptions to patients admitted to a neonatal intensive care unit. METHOD: The records of all patients admitted during a three-month period were analyzed retrospectively. Study endpoints were all prescribed medications, including dosage, route and form of administration. Medications were categorized in three groups: licenced, unlicenced and off-label medications. RESULTS: A total of 81 patients with a total of 84 admissions (3 re-admissions) had a median length of stay of 6 days (range: 1-101 days) in the intensive care unit. Of the 84 admissions, 20 were attributable to heart surgery conditions and 11 to extremely low birth weight (less than 1 000 g). A total of 748 prescriptions of 82 different medications were registered with an average of 6 (range: 1-38) different drugs per stay. 364 prescriptions (49%) were licenced, 250 (34%) were off-label, and 134 (18%) were unlicenced. During 77% of all 84 admissions, we used at least one off-label or unlicenced drug. CONCLUSION: The data of our study demonstrate that the availability of licenced drugs for neonates is greatly limited. The results are consistent with studies in other European countries. This study underlines once more the need of adequate testing of medicines in children to assess their safety and efficacy. Whether the new European regulation will achieve this goal remains to be seen.
