Research Summary Vesicoureteral reflux (VUR), or the reversed flow of urine from the bladder back up into the kidney, is a common pediatric condition, which is present in up to 10% of all children in the United States. In the setting of urinary tract infection, VUR can be present in up to 50% of otherwise healthy children. In these children, VUR increases the risk of renal scarring, hypertension, proteinuria, and, in extreme cases, end-stage renal disease. Although it is clear that VUR-related, long-term renal problems have a significant impact on affected children, there are children who suffer no VUR-related consequences whatsoever. Unfortunately, VUR research has to date been unable to identify which children are most at risk of VUR-related renal damage. This lack of risk stratification has led to tremendous variation in VUR management: some physicians treat VUR with surgery, others with endoscopy, and others with long-term antibiotics. It remains unclear which of these approaches works best for which children. My long-term career goal is to improve the health of children with VUR and other urological conditions by the application of health services research methods. As a pediatric urologist and a health services researcher, I am in the process of establishing an independent research career in a field where health services research has not yet reached its full potential. Pediatric urology is a subspecialty in the midst of a fundamental shift in its approach to clinical research. My predecessors laid the foundations for urologic research based primarily on their personal clinical and surgical experience; my peers have begun to shift to research based on large-scale observational studies and randomized trials. I plan to contribute to this transformation by introducing comparative effectiveness methodology to the field. My short-term goals are: (1) To further develop my knowledge of techniques and methodologies for comparative-effectiveness research using tools such as observational and administrative databases; (2) to learn and apply the techniques of decision analysis in order to guide clinical decision-making in children with VUR and to support guideline development for VUR treatments; and (3) to develop the foundation for future clinical research of VUR and for future independent funding proposals for this research. To facilitate these goals, I will use the strengths of comparative-effectiveness research to determine which children with VUR will benefit most from which treatment. In Aim 1a, we will use a national database to define the incidence of critical clinical outcomes, such as the incidence of urinary infections after VUR treatment. In Aim 1b, we will validate those findings in a second national database to ensure that our findings are broadly applicable to children with varying disease severity and socioeconomic backgrounds. In Aim 2, we will survey community members to determine patient- and community-based VUR treatment preferences. In the long term, these projects will form the basis for a subsequent R01 application focused on VUR. In the next 5 years I will develop the research expertise and infrastructure to support an active clinical and health services research program, and I will focus that expertise and infrastructure on the most common and most clinically significant conditions in pediatric urology.

研究总结 膀胱输尿管反流(VUR)，或尿液从膀胱反向流入肾脏，是一种 常见的儿科疾病，在美国高达10%的儿童中存在这种情况。在环境中 由于尿路感染，VUR可出现在高达50%的其他健康儿童中。在这些儿童中，VUR 增加肾脏疤痕、高血压、蛋白尿的风险，在极端情况下，还会增加终末期肾脏疾病的风险。 尽管很明显，与输尿管返流相关的长期肾脏问题对受影响的儿童有重大影响， 有一些儿童没有遭受任何与VUR相关的后果。不幸的是，VUR研究不得不 Date无法确定哪些儿童最有可能受到VUR相关的肾脏损害。这种风险的缺乏 分层导致了VUR管理的巨大变化：一些医生通过手术治疗VUR， 其他人使用内窥镜检查，其他人使用长期抗生素。目前还不清楚这些方法中的哪种 对哪种孩子最有效。 我的长期职业目标是改善患有VUR和其他泌尿系统疾病的儿童的健康状况 卫生服务研究方法的应用。作为一名儿科泌尿科医生和卫生服务研究人员，我 我正在卫生服务研究领域建立独立的研究生涯 还没有充分发挥其潜力。儿科泌尿科是正在发生根本性转变的一个子专业。 临床研究的方法。我的前辈们奠定了泌尿学研究的基础，主要基于 他们的个人临床和手术经验；我的同行已经开始转向基于大规模 观察性研究和随机试验。我计划通过以下方式为这一转变做出贡献： 实地比较有效性方法论。 我的短期目标是：(1)进一步发展我的技术和方法论知识 使用观察和行政数据库等工具进行有效性比较研究；(2) 学习和应用决策分析技术指导儿童精神分裂症临床决策 以及(3)为未来发展奠定基础。 VUR的临床研究和这项研究的未来独立资助建议。 为了促进这些目标，我将利用比较有效性研究的优势来确定 哪些VUR儿童将从哪种治疗中受益最多。在目标1a中，我们将使用一个国家数据库 确定关键临床结局的发生率，例如VUR后尿路感染的发生率 治疗。在目标1b中，我们将在第二个国家数据库中验证这些发现，以确保我们的发现 广泛适用于具有不同疾病严重程度和社会经济背景的儿童。在目标2中，我们 将对社区成员进行调查，以确定患者和社区为基础的VUR治疗偏好。 从长远来看，这些项目将为随后的以VUR为重点的R01应用奠定基础。在……里面 在接下来的5年里，我将发展研究专业知识和基础设施，以支持积极的临床和健康 服务研究计划，我将把专业知识和基础设施集中在最常见和最 儿科泌尿科的临床重要病症。
