Aim: The aim of this study was to test the hypothesis that singleton late preterm infants (34 0/7 to 36 6/7 weeks of gestation) compared with full‐term infants have a higher incidence of short‐term morbidity and stay longer in hospital. Methods: In this retrospective, multicentre study, electronic data of children born at five hospitals in Switzerland were recorded. Short‐term outcome of late preterm infants was compared with a control group of full‐term infants (39 0/7 to 40 6/7 weeks of gestation). Multiple gestations, pregnancies complicated by foetal malformations, maternal consumption of illicit drugs and infants with incomplete documentation were excluded. The results were corrected for gender imbalance. Results: Data from 530 late preterm and 1686 full‐term infants were analysed. Compared with full‐term infants, late preterm infants had a significant higher morbidity: respiratory distress (34.7% vs. 4.6%), hyperbilirubinaemia (47.7% vs. 3.4%), hypoglycaemia (14.3% vs. 0.6%), hypothermia (2.5% vs. 0.6%) and duration of hospitalization (mean, 9.9 days vs. 5.2 days). The risk to develop at least one complication was 7.6 (95% CI: 6.2–9.6) times higher among late preterm infants (70.8%) than among full‐term infants (9.3%). Conclusion: Singleton late preterm infants show considerably higher rate of medical complications and prolonged hospital stay compared with matched full‐term infants and therefore need more medical and financial resources.
