项目摘要
DESCRIPTION (provided by applicant): Because effective antiretroviral therapy substantially reduces viral load, hence the likelihood of transmission, the ultimate goal of the cascade--helping persons living with HIV (PLWH) reach undetectable viral load status--is crucial if we are to reduce forward transmission of the virus to negligible levels and, at the same time, ensure that PLWH live long and productive lives. Importantly, behavioral interventions are needed to complement and ensure the success of their biomedical counterparts at every step along the treatment cascade, whether to help a person living with HIV advance from one state of the cascade to another or to remain at the same cascade state. This application is motivated by the critical need for a uniform methodology for estimating the HIV prevention effectiveness of interventions along the HIV treatment cascade. No such methodology currently exists. HIV prevention effectiveness estimates, along with other health benefit estimates, are needed to estimate the cost-effectiveness of these interventions, and thereby to help public health decision makers select the most economically-efficient intervention for a particular purpose (e.g., linking new-diagnosed persons to care) or to choose between interventions at different stages along the cascade. We propose to refine and extend to treatment cascade interventions an existing method--based on HIV transmission rates--for estimating the number of sexually-transmitted HIV infections averted by preventive interventions, which is a necessary first step toward evaluating the cost-effectiveness of treatment cascade interventions. Uniformity is the key to making cost-effectiveness information meaningful. Only when uniform methods are used to evaluate the effectiveness of disparate interventions can the results of these analyses be compared. We believe a uniform methodology for assessing the HIV prevention effectiveness of cascade- related interventions can be developed using the concept of HIV transmission rates. Each stage of the treatment cascade is associated with a particular HIV transmission rate. The difference in transmission rates from one stage of the cascade to the next one indicates the number of HIV infections prevented, per unit time, by an intervention that helps a person living with HIV advance from the former to the latter cascade stage. The Specific Aims of the proposed research project are: (1) To conduct a thorough search of the published and grey literatures to obtain current information needed to estimate the proportionate reduction in risk associated with the transition from one state of the cascade to another; (2) Based on the empirical evidence obtained in Aim 1, to estimate the average transmission rates for stages along the HIV treatment cascade, along with plausible ranges; and (3) To assess the cost-effectiveness of two cascade interventions of demonstrated effectiveness.
描述(由申请人提供):由于有效的抗逆转录病毒疗法大大降低了病毒载量,从而降低了传播的可能性,如果我们要将病毒的前向传播减少到可以忽略的水平,同时确保艾滋病毒感染者(PLWH)长寿和富有成效的生活,级联的最终目标-帮助艾滋病毒感染者(PLWH)达到不可检测的病毒载量状态-至关重要。重要的是,行为干预是必要的,以补充和确保其生物医学同行在治疗级联的每一个步骤沿着的成功,无论是帮助艾滋病毒感染者从级联的一个状态前进到另一个状态,还是保持在同一级联状态。 这一应用的动机是迫切需要一种统一的方法来估计艾滋病毒预防干预措施的有效性沿着艾滋病毒治疗级联。目前没有这种方法。艾滋病毒预防效果估计,沿着其他健康效益估计,需要估计这些干预措施的成本效益,从而帮助公共卫生决策者为特定目的选择最经济有效的干预措施(例如,将新诊断的人与护理联系起来)或在级联过程的沿着不同阶段选择干预措施。我们建议完善和扩大现有的方法-基于艾滋病毒传播率-用于估计预防性干预措施避免的性传播艾滋病毒感染的数量,这是评估治疗级联干预措施的成本效益的必要的第一步。 一致性是使成本效益信息有意义的关键。只有当统一的方法被用来评估不同干预措施的有效性时,这些分析的结果才能被比较。我们认为,利用艾滋病毒传播率的概念,可以制定一种评估级联相关干预措施预防艾滋病毒有效性的统一方法。治疗级联的每个阶段都与特定的艾滋病毒传播率有关。从级联的一个阶段到下一个阶段的传播率差异表明,通过帮助艾滋病毒感染者从前一个级联阶段进入后一个级联阶段的干预措施,单位时间内预防的艾滋病毒感染人数。 建议研究项目的具体目标是:(1)对已发表的和灰色的文献进行彻底的检索,以获得估计从级联的一种状态过渡到另一种状态的风险降低比例所需的最新信息;(2)根据目标1中获得的经验证据,估计艾滋病毒治疗级联过程中沿着各阶段的平均传播率,沿着合理的范围;(3)评估两个级联干预措施的成本效益证明的有效性。
