Background: Current American Academy of Pediatrics guidelines recommend discharge at physiologic maturity regardless of weight; however, our institution's neonatal ICU policy requires a minimum weight of 1800 g for discharge even when infant is physiologically mature. So, we wanted to determine if discharge at physiologic maturity (PM), based on national guidelines, would decrease hospital days (HD).
Methods: We reviewed 129 infants with birthweight 1300g- 1800 g. Data were analyzed by paired t-test/ Wilcoxon-rank-sum test.
Results: Age at discharge vs. age at PM was 0.55d per infant higher (P-value 0.033) resulting in 71 total HD. For SGA babies, this difference was 1.47d vs 0.19d in non-SGA babies (P- value 0.0243) and this difference was an average of 2.63d (P-value < 0.001) for those who reached PM < 1800 g, contributing to 50 of 71 HD potentially saved.
Conclusion: There was a 0.55-2.6-day difference between age at discharge and age at PM, greater in SGA infants and infants who reached PM prior to 1800 g. There might be an opportunity to send infants home earlier to their families if there is no minimum weight required.
