This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The purpose of this study is to provide a registry of baseline and outcome data for very low birth weight infants, based on data collected in a uniform manner from neonatal intensive care units (NICUs) at institutions participating in the NICHD Neonatal Research Network. These data represent a number of major tertiary care academic centers, whose patients exemplify the range of neonatal morbidity. These data will be used to characterize the infants admitted to the units, to examine the relationships between certain entry characteristics and outcome, to measure trends in incidence of various disease entities, and to provide the basis of hypothesis formulation for future multicenter studies. Baseline and outcome data will be collected on all liveborn infants with birth weight from 401 to 1500 grams who are admitted to the NICUs within 14 days of birth or infants with a heart rate above zero at birth. These data will be obtained by review of the mothers' and babies' charts. The data forms for the survey have been named 'generic data forms' in recognition of the fact that the information collected is of universal interest and not specific to a particular disease or treatment. They provide a descriptive summary of the babies' background, perinatal and neonatal experience. Baseline data will be obtained soon after admission to the NICU and the outcome data will be obtained at the time of discharge from the NICU.
