Abstract
PURPOSE
We aimed to describe the differences in clinical characteristics that affect readmission between late and moderate preterm or full-term infants.
METHODS
Medical records were reviewed for 881 patients with gestational ages of ≥31⁺⁰ weeks who were born at Inje University Sanggye Paik Hospital between1 January 2013 and 20 September 2015. The patients were categorized into three subgroups as follows moderate preterm infants: those born at 31-33 weeks' gestation (n=73), late preterm infants: those born at 34–36 weeks' gestation (n=169),and full-term infants: those born at ≥37 weeks' gestation (n=639). We compared the late and moderate preterm or full-term infants in terms of clinical characteristics that affect readmission.
RESULTS
The readmission rate was 18.9% in the late preterm infants, 21.9% in the moderate preterm infants, and 16.7% in the full-term infants. The independent risk factors of readmission were gestational age in the late preterm infants, positive pressure ventilation at birth in the moderate preterm infants, and air-leak syndrome in the full-term infants. In addition, antenatal care at the first trimester of pregnancy was an independent protective factor against readmission in the full-term infants.
CONCLUSION
Our results suggest that gestational age may affect the readmission rate of late preterm infants.
