Abstract

OBJECTIVES

The authors evaluated the cost-effectiveness of a community-level HIV prevention intervention that used peer leaders to endorse risk reduction among gay men.

METHODS

A mathematical model of HIV transmission was used to translate reported changes in sexual behavior into an estimate of the number of HIV infections averted.

RESULTS

The intervention cost $17,150, or about $65,000 per infection averted, and was therefore cost-saving, even under very conservative modeling assumptions.

CONCLUSIONS

For this intervention, the cost of HIV prevention was more than offset by savings in averted future medical care costs. Community-level interventions to prevent HIV transmission that use existing social networks can be highly cost-effective.

摘要

目的

作者评估了一项社区层面的艾滋病毒预防干预措施的成本效益,该干预措施利用同伴领袖来倡导男同性恋者降低风险。

方法

使用艾滋病毒传播的数学模型,将报告的性行为变化转化为对避免的艾滋病毒感染数量的估计。

结果

该干预措施花费了17,150美元,即每避免一例感染约65,000美元,因此即使在非常保守的模型假设下也是节省成本的。

结论

对于这项干预措施,艾滋病毒预防的成本被未来避免的医疗护理成本节省所抵消。利用现有社会网络预防艾滋病毒传播的社区层面干预措施可能具有很高的成本效益。
