SCRN Chart Abstraction Prenatal Invasive Diagnostics Dataset in Stillbirth Collaborative Research Network Study

Data on whether prenatal invasive diagnostic procedures performed, timing, indication and results of procedure performed (Prenatal Invasive Diagnostic Procedures Form 04I)
Study Description
Population-based case–control study of the causes and extent of stillbirth (SB) in the United States. Participants were recruited at delivery between March 2006 and September 2008 from 59 urban and rural hospitals in 5 geographic areas. All women with SB and a representative sample of women with live births, oversampled for those delivering at <32 weeks gestation and those of African descent delivering at =32 weeks gestation, were approached for enrollment. Pregnancy terminations were excluded. The study included maternal interview, chart abstraction, placental exam, and postmortem (SB only). Data collection focused on surveillance and epidemiology, maternal disease, immunology and infections, placental pathology, and genetics. A subset of SCRN participants consented to re-contact which examined subsequent pregnancies and pregnancy complications, grief resolution, and whether life-course stresses and environmental factors were associated with an increased risk of SB. Biospecimens are available. Women who delivered a stillbirth or live birth and consented to participate in the Stillbirth Collaborative Research Network Study and their babies

本数据集涵盖产前侵入性诊断操作（Prenatal Invasive Diagnostic Procedures）的实施情况、操作时机、指征及操作结果（产前侵入性诊断操作表格04I）。
研究描述
本研究为美国地区针对死产（stillbirth, SB）的病因与严重程度开展的人群为基础的病例对照研究。研究于2006年3月至2008年9月期间，从5个地理区域的59家城乡医院的分娩环节招募参与者：所有死产产妇以及活产产妇的代表性样本，其中针对妊娠<32周分娩者与妊娠≥32周分娩的非裔产妇进行了过度抽样，所有符合条件的对象均被邀请参与本研究。妊娠终止者被排除出研究范围。
研究内容包含产妇访谈、病历摘录、胎盘检查以及尸检（仅针对死产病例）。数据采集聚焦于监测与流行病学、产妇疾病、免疫学与感染学、胎盘病理学以及遗传学领域。
死产协作研究网络（Stillbirth Collaborative Research Network, SCRN）的部分参与者同意接受再次随访，该随访评估了后续妊娠与妊娠并发症、悲伤情绪缓解情况，以及生命历程应激与环境因素是否与死产风险升高相关。
本研究留存有生物样本。
研究对象为同意参与死产协作研究网络研究的死产或活产产妇及其新生儿。
