ADDRESSING TB CONTROL AND LUNG HEALTH ACTIVITIES THROUGH THE VIETNAM NATIONAL LUN

描述(申请人提供)：结核病(TB)是艾滋病毒携带者(PLHIV)的主要死因，建议对所有PLHIV感染者进行结核病筛查。通过在越南、泰国和柬埔寨进行的三个国家的“ID-TB/HIV研究”，确定了一种基于证据的结核病筛查和诊断方法。根据ID-TB/HIV研究得出的结核病筛查算法目前正在越南的两个城市实施和评估，作为CDC确定为非研究的一次性筛查的方案实施和评估。ID-TB/HIV研究没有解决的一个悬而未决的问题是，当随着时间的推移重复使用ID-TB/HIV算法在PLHIV中筛查结核病时，会产生什么效果。这项研究将通过随着时间的推移重复应用算法来评估这个问题，这些参与者同意将基线筛选作为方案评估的一部分。

DESCRIPTION (provided by applicant): Tuberculosis (TB) is a leading cause of death among persons living with HIV (PLHIV), and screening for TB in all PLHIV is recommended. An evidence-based approach to TB screening and diagnosis was identified through the three-country "ID-TB/HIV study" conducted in Vietnam, Thailand and Cambodia. The TB screening algorithm derived from the ID-TB/HIV study is now being implemented and evaluated in two cities in Vietnam as a programmatic implementation and evaluation of one-time screening, determined to be non-research by CDC. An outstanding question not addressed by the ID-TB/HIV study is the yield of using the ID-TB/HIV algorithm when used repeatedly over time to screen for TB among PLHIV. This study will assess that question by applying the algorithm repeatedly over time for consenting participants who have had baseline screening as part of the programmatic evaluation.
