DESCRIPTION (provided by applicant): This patient-oriented mentored career development award proposal is designed to support the transition of Dr. Tellen D. Bennett into an independent clinician-scientist and national leader in quantitative comparative effectiveness research. Dr. Bennett is an Assistant Professor of Pediatric Critical Care at the University of Utah. He has prior training in epidemiology and comparative effectiveness research methods, and his research is focused on improving outcomes in children with traumatic brain injury (TBI). This proposal will allow Dr. Bennett to develop skills in probabilistic database linkage, prospective cohort studies, propensity methods, multiple imputations, and mixed models. Drs. Mike Dean and Heather Keenan, Dr. Bennett's co- mentors, have extensive expertise in clinical trials, injury research, epidemiology, and large databases. His multidisciplinary advisory committee is made up of national leaders in pediatric trauma and traumatic brain injury, neurosurgery, the Pediatric Health Information System (PHIS) and National Trauma Data Bank (NTDB) databases, probabilistic linkage, and the statistics of comparative effectiveness research methods. Dr. Bennett's over-arching career goal is to improve the outcomes of children with severe TBI and other injuries using comparative effectiveness research methods. His short-term career goal is to become a national expert in pediatric TBI research and quantitative comparative effectiveness methods. Dr. Bennett's long-term career goal is to be an independent clinician-scientist who will: 1) Improve outcomes in children with TBI by analyzing the effect of interventions (intracranial pressure (ICP) monitoring, osmolar therapy, and others) in the linked dataset developed and validated in this proposal, 2) Collaborate with trauma surgeons and others to expand the PHIS-NTDB linkage to perform comparative effectiveness analyses of interventions in children with other injuries, and 3) Participate in multi-center cohort studies an trials conducted through pediatric research networks. The Division of Pediatric Critical Care and the Department of Pediatrics at the University of Utah have a culture of collaborative research that bridges barriers and enables physician scientists to work with local institutions such as Intermountain Healthcare (IHC) and national organizations such as the American College of Surgeons (ACS) and the Children's Hospital Association (CHA, formerly CHCA). The University of Utah and the Department of Pediatrics have outstanding resources for the early development and mentorship of junior investigators, including the NIH-funded Center for Clinical and Translational Science (CCTS) and the NIH- funded training program in Translational and Comparative Effectiveness Research (TCER, Dr. Bennett is a funded Mentored Scholar and currently has 75% protected time). The Division of Pediatric Critical Care maintains a robust computing infrastructure and statistical and information technology staff in order to provide data management, logistical support, and analyses for several large pediatric research networks. All of these resources contribute to the research environment and are available to ensure Dr. Bennett's continued success. Research: TBI causes substantial death and disability in children. The available evidence to support acute interventions in children with severe TBI (Glasgow Coma Scale d 8) is limited. This proposal aims to link and validate two national databases with complementary clinical information, and then conduct a comparative effectiveness analysis of intracranial pressure monitoring in children with severe TBI. Elevated ICP frequently results from severe TBI and worsens patient outcome by causing additional brain injury. ICP monitoring is used to detect elevated ICP and to guide treatment of severe TBI. Treatment of elevated ICP is known to improve outcomes in adults; however, the risk/benefit ratio of ICP monitoring in children is less clear. In spite of this, expert opinion recommends ICP monitoring in children with severe TBI, making a clinical trial of ICP monitoring unlikely. Therefore, observational methods are the best available techniques to assess the effectiveness of ICP monitoring in children. Aim 1 is to use probabilistic linkage techniques to link the PHIS and the NTDB databases and to validate the accuracy of that linkage using retrospective data from one hospital. Aim 2 is to validate the accuracy of database codes in the linked dataset and a proxy poor functional outcome, survival with tracheostomy and gastrostomy, by conducting a three-year prospective cohort study at a single, high volume, pediatric trauma center. Aim 3 is to test the hypothesis that intracranial pressure (ICP) monitoring is associated with a lower likelihood of hospital mortality or poor functional outcome in children with severe TBI. The PIs will validate the result of Aim 3 by repeating the dataset linkage and the comparative effectiveness analysis four years later. Completion of these studies and his training aims will allow Dr. Bennett to generate invaluable information to guide the acute care of children with TBI and to become an independent investigator and national leader in pediatric TBI research and comparative effectiveness research methods.

描述（由申请人提供）：这个以患者为导向的指导职业发展奖提案旨在支持telen D. Bennett博士向独立临床科学家和定量比较有效性研究的国家领导者的过渡。贝内特博士是犹他大学儿科重症监护助理教授。他之前接受过流行病学和比较有效性研究方法方面的培训，他的研究重点是改善创伤性脑损伤（TBI）儿童的预后。该提案将允许Bennett博士发展概率数据库链接、前瞻性队列研究、倾向方法、多重imputation和混合模型方面的技能。Drs。Mike Dean和Heather Keenan， Bennett博士的共同导师，在临床试验，损伤研究，流行病学和大型数据库方面拥有广泛的专业知识。他的多学科咨询委员会由儿科创伤和创伤性脑损伤、神经外科、儿科卫生信息系统（PHIS）和国家创伤数据库（NTDB）数据库、概率联系和比较有效性研究方法统计方面的国家领导人组成。贝内特博士的首要职业目标是用比较有效的研究方法改善患有严重脑外伤和其他损伤的儿童的预后。他的短期职业目标是成为儿科TBI研究和定量比较有效性方法的全国专家。贝内特博士的长期职业目标是成为一名独立的临床科学家，他将：1)通过分析本建议开发并验证的关联数据集中干预措施（颅内压（ICP）监测、渗透压治疗等）的效果，改善TBI儿童的结局；2)与创伤外科医生等合作，扩大PHIS-NTDB链接，对其他损伤儿童的干预措施进行比较有效性分析；3)参与多中心队列研究和通过儿科研究网络进行的试验。犹他大学儿科重症监护室和儿科部门具有合作研究的文化，可以消除障碍，使医生科学家能够与当地机构（如山间医疗保健（IHC））和国家组织（如美国外科医生学会（ACS）和儿童医院协会（CHA，以前的CHCA））合作。犹他大学和儿科部门拥有优秀的资源，可以为初级研究人员提供早期发展和指导，包括美国国立卫生研究院资助的临床和转化科学中心（CCTS）和美国国立卫生研究院资助的转化和比较有效性研究培训计划（TCER， Bennett博士是资助的导师学者，目前有75%的保护时间）。儿科重症护理司拥有强大的计算基础设施以及统计和信息技术人员，以便为几个大型儿科研究网络提供数据管理、后勤支持和分析。所有这些资源都有助于研究环境，并可确保贝内特博士的持续成功。研究：脑外伤导致大量儿童死亡和残疾。支持急性干预治疗严重TBI儿童（格拉斯哥昏迷量表d 8）的现有证据有限。本提案旨在连接和验证两个具有互补临床信息的国家数据库，然后对重型颅脑损伤儿童颅内压监测进行比较效果分析。颅内压升高通常由严重的脑外伤引起，并通过引起额外的脑损伤而使患者预后恶化。ICP监测用于检测ICP升高并指导严重TBI的治疗。已知治疗ICP升高可改善成人的预后；然而，儿童ICP监测的风险/收益比尚不清楚。尽管如此，专家意见建议监测ICP的儿童患有
