介绍。一项以社区为基础的干预计划发现，高风险目标人群与周围社区相互作用，成为毒品和卖淫的来源，形成了一种衡量每个群体健康状况相互依赖的方法。干预措施收集了目标人群中有关性行为和吸毒行为的大量数据。动态隔室模型估计干预的流行病学影响，这是比较干预成本和终生艾滋病毒治疗成本的经济评估的基础。大约2/3的新感染发生在周边社区。干预措施在周边社区的溢出效益足以使干预措施第一年节省成本-节省约53.4万美元。进行干预不仅对风险群体，而且对其所在的整个社区都有健康效益和成本节约。量化溢出效应对于试图分配稀缺公共卫生资源的政策制定者至关重要。
Introduction. A community-based intervention program found that the high-risk target population interacts with its surrounding community as a source of drugs and prostitution, creating a measure of co-dependence in the health status of each group.Methodology. The intervention collected extensive data on sexual and drug use practices in the target population. A dynamic compartment model estimates the epidemiological impact of the intervention, which serves as the basis for the economic assessment comparing intervention costs and lifetime HIV treatment costs.Results. Approximately 2/3 of the new infections arise in the surrounding community. Intervention spillover benefits in the surrounding community are sufficient to make the intervention cost-saving in the first year—a savings of ∼$534,000.Conclusions. Conducting the intervention results in health benefits and cost-savings not only for the risk group, but for the entire community in which it resides. Quantifying the spillovers is vital to policymakers attempting to allocate scarce public health resources.
