DESCRIPTION (provided by applicant): This four-year K01 award application is to provide intensive multi-disciplinary training and career development guidance for Dr. Yu-Hsiang Hsieh, PhD, an Assistant Professor in Emergency Medicine at the Johns Hopkins University, leading to his becoming an independent investigator. Under the guidance of world renowned, NIH-funded, experienced mentors, Drs. Richard Rothman, Joshua Epstein, and David Holtgrave, Dr. Hsieh will gain a set of complementary inter-disciplinary skills which will allow him to pursue research with a focus on devising and evaluating public health interventions for infectious diseases seen in acute care settings. The applicant will receive mentoring in: public health aspects of emergency medicine; infectious disease computational mathematical modeling; and cost-effectiveness analysis. The rationale for the work, evaluation of HIV screening strategies, comes from the fact that HIV incidence has remained unchanged in the U.S. over the past decade, with one in five infected remaining unaware of their serostatus. One of the cornerstones recently advanced by the CDC for controlling the epidemic is widespread screening in emergency department (ED) settings. While, increasing numbers of EDs across the U.S. have developed strategies to adapt HIV testing into routine practice, there have been no efforts to systematically address how effective ED-based HIV testing has been (relative to no ED-based testing), or, which of several testing strategies is optimal with regard to identifying the largest number of unrecognized cases, and decreasing community HIV transmission. A relatively new and innovative method of computational modeling, agent-based modeling (ABM), offers a potential means for handling the complexity of temporal dynamics of HIV epidemiology and human behaviors associated with availability of ED-based HIV testing services, and represents a promising approach for overcoming many of the shortcoming of conventional study designs. The goal of this research project is to: 1) derive a computational model for measuring the impact of ED HIV testing programs on the HIV epidemic in Baltimore, Maryland, using ABM methods; 2) validate the derived ABM model; and 3) assess relative cost- effectiveness of ED HIV testing programs based on findings from the validated ABM model. The results of this study will provide new insights regarding current approaches to ED-based HIV testing programs and provide important cost-effectiveness data to inform local and national HIV testing strategies. The K01 award will provide Dr. Hsieh an intensive and directed mentored research experience in two new disciplines for him - infectious disease computational mathematical modeling, particularly ABM, and cost-effectiveness analysis. He will also receive needed training in the responsible conduct of research as well as longitudinal career guidance from an experience team. Together these experiences will equip him with the essential training and mentorship necessary to become an outstanding interdisciplinary independent public health investigator, who will build a research program focused on the study of infectious diseases in emergent, and acute care venues.

简介（由申请人提供）：这项为期四年的K01奖申请，旨在为约翰霍普金斯大学急诊医学助理教授谢玉祥博士提供密集的多学科培训和职业发展指导，使他成为一名独立的研究者。在世界知名、nih资助、经验丰富的导师的指导下，Richard Rothman， Joshua Epstein和David Holtgrave，谢博士将获得一系列互补的跨学科技能，这将使他能够专注于设计和评估急性护理环境中传染病的公共卫生干预措施的研究。申请人将获得以下方面的指导：急诊医学的公共卫生方面；传染病计算数学建模；以及成本效益分析。这项工作的基本原理，评估艾滋病毒筛查策略，来自这样一个事实，即在过去的十年里，美国的艾滋病毒发病率保持不变，五分之一的感染者仍然不知道自己的血清状态。疾病预防控制中心最近提出的控制流行病的基石之一是在急诊科（ED）环境中进行广泛筛查。尽管美国越来越多的急诊医生已经制定了将艾滋病毒检测纳入常规实践的策略，但还没有系统性的努力
