SURVEY OF MORBIDITY AND MORTALITY AMONG VERY LOW BIRTH WEIGH

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 这项研究的目的是提供极低出生体重儿(1501克)的基线和结局数据登记，其基础是以统一的方式从参与NICHD新生儿研究网络的机构的新生儿重症监护病房(NICU)收集的数据。该数据库将被用来描述进入参与NICU的婴儿的特征，检查某些进入特征和结果之间的关系，衡量各种疾病实体的发病率趋势，并为未来多中心研究的假设制定提供基础。 将收集所有出生体重在401至1500克之间、在出生后14天内进入参与NICU的活产婴儿或在产房死亡的出生时心率正常的婴儿的基线和结局数据。这些数据将通过查看母亲和婴儿的图表获得。这只是一项图表回顾研究，不涉及任何程序或干预。

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 (1501 grams), based on data collected in a uniform manner from neonatal intensive care units (NICUs) at institutions participating in the NICHD Neonatal Research Network. The data base will be used to characterize the infants admitted to the participating NICUs, to examine the relationships between certain entry characteristics and outcome, to measure trends in incidence of various disease entities, and to provide the basis for hypothesis formulation for future multi-center 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 participating NICUs within 14 days of birth or infants with a heart rate at birth who died in the delivery room. These data will be obtained by review of the mother's and baby's charts. This is a chart review study only, no procedures or interventions are involved.
