DESCRIPTION (provided by applicant): Blacks bear a disproportionate burden of asthma morbidity and mortality. In its 2005 report on ethnic disparities in health care, AHRQ identified hospital admissions for asthma as the second largest disparity in quality of health care for Blacks versus Whites. The BELT study (Blacks and Exacerbations on LABA vs. Tiotropium; 1R01HS019408- 01) was funded through AHRQ to compare the effectiveness of long-acting beta agonists (LABA)/inhaled corticosteroids (ICS) vs. Tiotropium/ICS in delaying the time to exacerbation in Black patients with asthma. This study enrolled >1000 subjects at 18 sites across the United States and followed them for at least 6 months and up to 18 months, while collecting robust asthma outcome data. To extend the usefulness and sustainability of the BELT study cohort dataset, the PESBART study is proposed. The objective of this proposal is to collect geographic environmental and stress data and to utilize a stakeholder engagement process over an 18-month period to develop new comparative effectiveness research questions and to enhance the current data infrastructure as relevant to the BELT cohort. The specific aims of this project are to: 1) increase the utility of the BELT data infrastructure by collecting geographic information on the environmental and stress exposures that may be associated with asthma outcomes; 2) preprocess the genotype data generated on a majority of BELT subjects in preparation for subsequent genetic analyses; 3) enhance sustainability and relevance of the BELT data infrastructure by involving a team of stakeholders with expertise in areas of environmental epidemiology, population genetics, clinical practice and patient advocacy; and 4) perform a Pilot study that will assess the completeness and accuracy of the geographic data elements and its ability to answer the research questions proposed by the PESBART Stakeholders. Understanding the interaction of environmental exposure, stress, and genetic determinants in contributing to asthma severity are important to individuals making decisions about where to live, policy makers in making decisions about locations for housing developments and other urban planning issues, and physicians interested in utilizing personalized treatment paradigms.

描述（由申请人提供）：黑人承担哮喘发病率和死亡率的不成比例负担。 AHRQ在2005年有关医疗保健种族差异的报告中，确定哮喘的住院是黑人与白人医疗保健质量的第二大差异。 The BELT study (Blacks and Exacerbations on LABA vs. Tiotropium; 1R01HS019408- 01) was funded through AHRQ to compare the effectiveness of long-acting beta agonists (LABA)/inhaled corticosteroids (ICS) vs. Tiotropium/ICS in delaying the time to exacerbation in Black patients with asthma.这项研究在整个美国的18个地点招收了> 1000名受试者，并关注了至少6个月和长达18个月，同时收集了强大的哮喘结果数据。为了扩展皮带研究队列数据集的有用性和可持续性，提出了Pesbart研究。该提案的目的是收集地理环境和压力数据，并在18个月的时间内利用利益相关者参与过程来制定新的比较有效性研究问题，并增强与Belt COHORT相关的当前数据基础架构。该项目的具体目的是：1）通过收集有关可能与哮喘结果相关的环境和压力暴露的地理信息来增加皮带数据基础设施的实用性； 2）预处理大多数皮带受试者生成的基因型数据为随后的遗传分析做准备； 3）通过在环境流行病学，人群遗传学，临床实践和患者倡导方面参与具有专业知识的利益相关者团队来提高皮带数据基础设施的可持续性和相关性； 4）进行试点研究，该研究将评估地理数据元素的完整性和准确性及其回答Pesbart利益相关者提出的研究问题的能力。了解环境暴露，压力和遗传决定因素在促成哮喘严重程度方面的相互作用对于做出决定居住地的个人，政策制定者在做出有关住房发展和其他城市规划问题的决策方面以及有兴趣利用个性化治疗范式的医生很重要。
