As a result of shorter postpartum hospital stays, many medical concerns, which traditionally have been managed in newborn nurseries, are presenting to the pediatric emergency department (PED). We undertook a study to determine the profile of early neonatal visits to the FED. In addition, we examined the influence of maternal factors and length of postpartum hospital stay on FED visits. Methods: We conducted a retrospective chart review of all neonates less than or equal to 8 days of age who presented to the FED between June 1990 and May 1995. Data gathered from neonatal and corresponding maternal charts included neonatal and maternal demographics, prenatal instruction, length of postpartum stay, source of referral, age at presentation, presenting complaint, diagnosis, disposition, and course in hospital, if admitted. Results: A total of 559 neonatal visits were identified. Neonatal use of the FED increased 245% compared to an overall increase in FED use of 8.7% during the study period. Jaundice, difficulty breathing, feeding problems, and irritability mere the most common presenting complaints while the most frequent diagnoses were normal physiology, jaundice, feeding problems, and query sepsis. Our overall admission rate was 33%. Self-referred patients were at a significantly lower risk of serious illness (16% admitted vs 49% of consult patients). The self-referral rate increased with maternal age less than 21, single marital status, no prenatal classes, and primiparity. The length of postpartum hospital stay was identified in 389 neonates (55 early discharge (ED) and 334 non-early discharge (NED). The ED group had a significant increase in annual FED utilization compared to the NED group changing from 2% of the total population in study year 1 to over 31% in the final year. The ED and NED groups did not differ significantly with respect to the majority of chief complaints, frequency of FED diagnoses, admission rates, or maternal characteristics. Conclusions: Use of the FED by neonates less than or equal to 8 days of age increased significantly over the study period. The majority of neonates presented by self-referral and were discharged with advice only. Mothers who were young, single, primiparous, or who had not attended prenatal classes presented with neonates who were less seriously ill. Although ED neonates represent an enlarging subset of FED visitors, they do not appear to differ significantly from NED neonates with respect to FED complaints, diagnoses, and disposition.
