This paper details a statistical method for evaluating needle exchange programmes. The approach relies only on needle exchange operations data and the results of HIV tests conducted on needles. We develop statistical models describing the needle infection process and how needle exchange interrupts this process. The method is illustrated using 20 months of data collected in conjunction with the evaluation of New Haven, Connecticut's needle exchange programme, and the results suggest that needle-borne HIV transmission among participating clients has been reduced by at least 33 per cent.
本文详细介绍了一种评估针头交换项目的统计方法。该方法仅依赖于针头交换操作数据以及对针头进行的艾滋病毒检测结果。我们开发了描述针头感染过程以及针头交换如何中断这一过程的统计模型。使用与康涅狄格州纽黑文市针头交换项目评估相关联收集的20个月数据对该方法进行了说明，结果表明参与项目的客户之间通过针头传播的艾滋病毒感染至少减少了33%。
