Objective: This study was conducted to determine if early postnatal discharge (EDC; < or =48 hours) in well newborns had an effect on the rate of hospital readmission within the first week after hospital discharge when compared to infants who remained >48 hours after birth (later discharge, LDC).
Study design: This was a retrospective medical chart review. Charts of infants born between January 1994 and December 1998, discharged as "well newborns" and treated subsequently at a primary children's hospital within 7 days of neonatal discharge, were reviewed. Infants were categorized by length of neonatal hospital stay, level of medical intervention (emergency department treatment or hospital admission), and final diagnosis.
Results: There was a significant increase in hospital readmission rate for LDC infants when compared to EDC infants. When considering jaundice alone as an admitting diagnosis, EDC infants were admitted at a higher rate than LDC infants and with higher serum bilirubin concentrations. Readmitted, jaundiced infants had been almost always breast-fed.
Conclusion: Overall, EDC of well newborns appears to be a safe and reasonable practice. However, the risk for severe jaundice is an unresolved issue that requires a discharge strategy and early follow-up to prevent serious morbidity.
