项目摘要
PROJECT SUMMARY
Antibiotic resistance is a significant threat to human health. Human therapeutic antibiotic use, the majority of
which occurs in outpatient settings for non-severe infections, is a major, modifiable driver of resistance. Acute
respiratory infections (ARIs) account for large proportions of outpatient antibiotic use and vaccines have been
recognized as important mechanisms to combat antibiotic use and resistance, especially for ARIs. However,
uncertainties remain in understanding the contributions of common respiratory pathogens to outpatient antibiotic
use and quantifying the full potential of vaccines to reduce antibiotic use, impeding informed policymaking and
priority-setting for vaccine research and development. The proposed research addresses these gaps in the
context of both existing and pipeline vaccines for three common respiratory pathogens in children: Streptococcus
pneumonaie, influenza virus, and respiratory syncytial virus (RSV). The objective of this proposed work is to
estimate impacts of both existing and potential vaccine strategies on outpatient antibiotic prescriptions for ARIs
in children. More specifically, the research focuses on the following aims: 1) estimate the attributable fractions
of ARI-associated pediatric outpatient antibiotic use due to vaccine-preventable respiratory pathogens; 2)
evaluate the impact of pneumococcal vaccination strategies on outpatient antibiotic use for ARIs in children; and
3) evaluate the impact of viral (influenza, RSV) vaccination strategies on outpatient antibiotic use for ARIs in
children. This project focuses specifically on ARIs in children as they are both major drivers of outpatient antibiotic
use and targets of existing and pipeline vaccines. The work will leverage multiple, complementary, large-scale
data sources including both claims data (Optum Clinformatics, IBM MarketScan) and nationally-representative
outpatient medical surveys (National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical
Care Survey), each with millions of pediatric ARI visits and outpatient antibiotic prescriptions per year, to address
these aims. The breadth of data and statistical and epidemiologic methods used in this proposed research will
enable a novel and comprehensive understanding of the potential for vaccines to reduce outpatient antibiotic
use for ARIs in children. This work will inform urgently-needed antibiotic resistance mitigation strategies and
priority setting and decision-making for vaccine research/development and policy. The proposed methods will
further provide a novel framework for evaluating current and future vaccines as outpatient infections and
antibiotic use are not commonly considered endpoints, despite their substantial burden. This research will be
enhanced by and complementary to my proposed training plan, which emphasizes development and experience
in epidemiologic and statistical methods, big data methods and applications, subject matter expertise, and
additional skills necessary for me to become an independent investigator. UC Berkeley, particularly the School
of Public Health, provides extensive resources and support to enable me to successfully complete the proposed
fellowship and fulfill my long-term goal of becoming a research-oriented infectious disease epidemiologist.
项目总结
抗生素耐药性是对人类健康的重大威胁。人类治疗性抗生素的使用,大多数
它发生在非严重感染的门诊环境中,是耐药性的主要、可改变的驱动因素。急性
呼吸道感染(ARI)占门诊抗生素使用的很大比例,疫苗已被
被认为是对抗抗生素使用和耐药性的重要机制,特别是对ARIS。然而,
在了解常见呼吸道病原体对门诊抗生素的贡献方面仍存在不确定性
使用和量化疫苗的全部潜力,以减少抗生素的使用,阻碍知情的决策和
确定疫苗研究和开发的优先事项。拟议的研究解决了这些差距,
儿童三种常见呼吸道病原体:链球菌的现有疫苗和正在研制的疫苗的背景
肺炎、流感病毒和呼吸道合胞病毒(RSV)。这项拟议工作的目标是
评估现有和潜在疫苗策略对急性呼吸窘迫综合征门诊抗生素处方的影响
在孩子们身上。更具体地说,本研究主要集中在以下几个方面:1)估计归因分数
疫苗可预防的呼吸道病原体导致的急性呼吸道感染相关儿科门诊抗生素使用情况;2)
评估肺炎球菌疫苗接种策略对儿童ARIS门诊抗生素使用的影响;以及
3)评估病毒(流感、RSV)疫苗接种策略对ARIS门诊抗生素使用的影响
孩子们。该项目特别关注儿童ARI,因为他们都是门诊抗生素的主要驱动力。
现有和正在研制的疫苗的用途和目标。这项工作将利用多个、互补、大规模的
数据来源包括索赔数据(Optom Clinformatics、IBM MarketScan)和全国代表性数据
门诊医疗调查(全国门诊医疗调查和国家医院门诊医疗调查
护理调查),每个人每年都有数百万次儿科ARI就诊和门诊抗生素处方,以解决
这些目标。这项拟议研究中使用的数据广度以及统计和流行病学方法将
能够对疫苗减少门诊抗生素的潜力有一个新的和全面的了解
在儿童中使用ARIS。这项工作将为迫切需要的抗生素耐药性缓解战略和
疫苗研发和政策的优先事项确定和决策。建议的方法将
进一步为评估当前和未来的疫苗作为门诊感染提供新的框架和
抗生素的使用通常不被认为是终点,尽管它们有很大的负担。这项研究将是
加强和补充我提出的培训计划,该计划强调发展和经验
在流行病学和统计学方法、大数据方法和应用、主题专门知识以及
成为一名独立调查员所需的其他技能。加州大学伯克利分校,特别是学校
公共卫生部,提供广泛的资源和支持,使我能够成功完成建议的
并实现我成为一名研究型传染病流行病学家的长期目标。
