Trends in hospitalization of preterm infants with intraventricular hemorrhage and hydrocephalus in the United States, 2000-2010

ObjectiveEven with improved prenatal and neonatal care, intraventricular hemorrhage (IVH) occurs in approximately 25-30% of preterm infants, and a subset of these patients develop hydrocephalus.We aim to describe current trends in hospitalization of preterm infants with IVH and post-hemorrhagic hydrocephalus (PHH) using the Nationwide Inpatient Sample (NIS) and Kids Inpatient Database (KID). MethodsThe KID and NIS databases were combined to generate data for the years 2000 -2010.All neonatal discharges with ICD9-CM codes for preterm birth with IVH alone or with IVH and hydrocephalus were included.
