The objective of this study was to examine supervised injecting facility (SIF) use among a cohort of 395 HIV-positive injection drug users (IDUs) in Vancouver, Canada. The correlates of SIF use were identified using generalized estimating equation analyses. In multivariate analyses, frequent SIF use was associated with homelessness (adjusted odds ratio [AOR] = 1.90), daily heroin injection (AOR = 1.56), and daily cocaine injection (AOR = 1.59). The reasons given for not using the SIF included a preference for injecting at home and already having a safe place to inject. The SIF services most commonly used were needle exchange and nursing services. The SIF appears to have attracted a high-risk subpopulation of HIV-positive IDUs; this coverage perhaps could be extended with the addition of HIV-specific services such as disease monitoring and the provision of antiretroviral therapy.
本研究的目的是调查加拿大温哥华395名艾滋病毒阳性注射吸毒者（IDU）队列中监督注射设施（SIF）的使用情况。使用广义估计方程分析确定SIF使用的相关因素。在多变量分析中，频繁使用SIF与无家可归（调整优势比[AOR]=1.90）、每日注射海洛因（AOR=1.56）和每日注射可卡因（AOR=1.59）有关。不使用SIF的原因包括更喜欢在家注射以及已经有一个安全的注射场所。最常用的SIF服务是针头交换和护理服务。SIF似乎吸引了艾滋病毒阳性IDU的高危亚人群；通过增加艾滋病毒特异性服务，如疾病监测和提供抗逆转录病毒疗法，这种覆盖范围或许可以扩大。
