使用应答者驱动抽样（RDS），我们收集了截至2007年10月1日在美国境外进行的128项HIV监测研究的数据。我们检查了不良研究结果的预测因素，审查了在国际环境中进行RDS的操作，设计和分析挑战，并提供了改进HIV监测的建议。我们使用平均样本量比率（招募/计算样本量）的差异作为结果变量，探讨了研究结果不佳的因素。92%的研究报告了计算和招募的样本量。与其他风险群体相比，对注射吸毒者的研究具有较高的样本量比率。研究挑战包括适当定义合格标准，构建社会网络规模问题，选择设计效果和进行统计分析。随着RDS越来越多地用于HIV监测，重要的是要从过去的实践，理论和分析挑战中学习，以最大限度地利用这种方法。
Using respondent-driven sampling (RDS), we gathered data from 128 HIV surveillance studies conducted outside the United States through October 1, 2007. We examined predictors of poor study outcomes, reviewed operational, design and analytical challenges associated with conducting RDS in international settings and offer recommendations to improve HIV surveillance. We explored factors for poor study outcomes using differences in mean sample size ratios (recruited/calculated sample size) as the outcome variable. Ninety-two percent of studies reported both calculated and recruited sample sizes. Studies of injecting drug users had a higher sample size ratio compared with other risk groups. Study challenges included appropriately defining eligibility criteria, structuring social network size questions, selecting design effects and conducting statistical analysis. As RDS is increasingly used for HIV surveillance, it is important to learn from past practical, theoretical and analytical challenges to maximize the utility of this method.
