DESCRIPTION (provided by applicant): This K99/R00 Award will provide the training in health services research and clinical obstetric practice needed to develop the candidate into an independent interdisciplinary researcher focusing on reproductive health disparities. The rate of cesarean delivery has reached epidemic proportions in the U.S. Overweight and obese women are at increased risk of cesarean, as well as short-term and long-term morbidities subsequent to cesarean delivery. However, very little is known about how to optimally provide obstetric care to overweight/obese women, to maximize their chance of successfully achieving a vaginal delivery. Patient- and systems-level factors are important determinants of mode of delivery. There are racial/ethnic disparities in cesarean delivery, and the relative contribution of obesity and race i unknown. Additionally, very little is known about the effect of busy (high-volume) days in Labor & Delivery on cesarean delivery rates. This project aims to disentangle the effects of obesity and race/ethnicity, and establish the impact of daily obstetric volume, on cesarean delivery. The proposed K99/R00 study will use a large administrative dataset containing a diverse population of births (California) to tease out the impact of obesity and race/ethnicity on mode of delivery, exploring the possibility of effect modification. Interaction of this type has been observed for obesity and race effects on other obstetric outcomes. The K99 phase will allow the candidate to develop a metric of daily obstetric volume, or how busy a Labor & Delivery unit is on a given day. In the R00 phase, the candidate will analyze the impact of high-volume days on the nulliparous, term, singleton, vertex cesarean delivery rate. Analyses will also be conducted within the overweight/obese populations and among subgroups of racial minority women, to see if altered processes of obstetric care affect their outcomes differentially. These innovative analyses and methodologies will provide much-needed information on non-medical predictors of cesarean delivery among women at the greatest risk of adverse pregnancy outcomes. Oregon Health and Science University is the ideal setting to conduct this training and research, because of its leadership in clinical obstetrics, obstetric outcomes research, and health services research. The candidate will also leverage the resources at the Oregon Clinical and Translational Research Institute to foster professional development and facilitate the transition to research independence.

描述(由申请者提供)：K99/R00奖将提供所需的卫生服务研究和产科临床实践方面的培训，以将候选人发展为专注于生殖健康差距的独立跨学科研究人员。在美国，剖腹产率已经达到流行的比例。超重和肥胖的妇女剖腹产的风险增加，剖腹产后的短期和长期发病率也增加。然而，关于如何以最佳方式为超重/肥胖妇女提供产科护理，以最大限度地增加她们成功实现阴道分娩的机会，人们知之甚少。患者和系统层面的因素是决定分娩方式的重要因素。在剖腹产方面存在种族/民族差异，肥胖症和种族的相对贡献尚不清楚。此外，人们对分娩高峰期对剖宫产率的影响知之甚少。该项目旨在理清肥胖和种族/民族的影响，并确定每日产科产量对剖腹产的影响。拟议的K99/R00研究将使用一个包含不同出生人口(加利福尼亚州)的大型管理数据集，梳理出肥胖和种族/民族对分娩方式的影响，探索影响修改的可能性。在肥胖和种族对其他产科结果的影响方面，已经观察到这种类型的交互作用。K99阶段将允许应聘者制定每天产科产量的衡量标准，或分娩单位在给定日期的忙碌程度。在R00阶段，候选人将分析大流量天数对未分娩、足月、单身、顶点剖宫产率的影响。还将在超重/肥胖人口和少数族裔妇女亚群中进行分析，以了解产科护理过程的改变是否会对她们的结果产生不同的影响。这些创新的分析和方法将提供急需的信息，说明在妊娠结局不良风险最大的妇女中剖腹产的非医学预测因素。俄勒冈健康与科学大学是进行这种培训和研究的理想场所，因为它在临床产科、产科结果研究和卫生服务研究方面处于领先地位。候选人还将利用俄勒冈州临床和翻译研究所的资源来促进专业发展并促进向研究独立性的过渡。
