Abstract
Objective
To compare the length of stay (LOS) against the expected date of delivery (EDD) and to describe mortality and LOS outcomes by gestational age (GA) categories over the years.
Study design
Healthcare Cost and Utilization Project Kids’ Inpatient database discharge records for years 2003, 2006, 2009, 2012, and 2016 were analyzed. For premature infants after inclusion–exclusion, actual, and calculated LOS were compared. Mortality and LOS outcomes were analyzed by GA and years.
Results
The majority (99%) of infants >28 weeks were discharged by EDD while, for neonate ≤28 weeks, about three-quarters (75%) of infants were discharged by calculated EDD. LOS is increasing while mortality is decreasing by GA categories in recent years.
Conclusions
This is the largest study of mortality and LOS in the United States. Our study provides evidence-based numbers comparing actual LOS against EDD, which can be used in perinatal settings to counsel parents.
